The design that the two guide blocks of the road pier annular shell are respectively arranged in the two guide grooves in a sliding fit mode ensures that the road pier annular shell can stably slide in the road pier base barrel.
Push pedal, bull stick, slider, swing guide, swing board, first ring gear, first planetary gear, first sun gear, first pivot, disc, second ring gear, second planetary gear, second sun gear, the design of threaded rod lie in: when the push plate is under the action of external force, the push plate drives the first gear ring to rotate through the rotating rod, the sliding block, the swing guide rail and the swing plate, the first gear ring drives the first sun gear to rotate through the first planetary gear, the first sun gear drives the disc to rotate through the first rotating shaft, the disc drives the second gear ring to rotate, the second gear ring drives the second sun gear to rotate through the second planetary gear, and the second sun gear drives the threaded rod to rotate. The second sun gear is rotated after a series of transmissions from the first gear ring, so that the second sun gear can rotate for multiple circles when the first gear ring rotates for a certain angle, and the threaded rod can have larger axial displacement under the threaded fit with the threaded ring sleeve.
According to the invention, the threaded rod can drive the ring disc to rotate in the cutting sleeve, and the threaded rod can move up and down and can also move up and down in the road pier base cylinder through the ring disc, the cutting sleeve and the fourth supporting plate with the road pier annular shell. The fourth supporting plate drives the second planetary gear to move up and down through the second fixed shaft; the road pier ring type shell can drive the second gear ring to move up and down through the second supporting plate and the second fixing ring; the road pier ring type shell can drive the first planetary gear to move up and down through the third supporting plate and the first fixed shaft; the road pier ring type shell can drive the first gear ring to move up and down through the first supporting plate and the first fixing ring; the first gear ring can drive the swing guide rail to move up and down through the swing plate. In a word, the cutting sleeve, the fourth supporting plate, the second fixed shaft, the second planetary gear, the second sun gear, the second gear ring, the disk, the second fixing ring, the second supporting plate, the third supporting plate, the first rotating shaft, the first fixed shaft, the first sun gear, the first supporting plate, the first fixing ring and the first planetary gear form a ring-shaped in-shell mechanism whole body, and when the threaded rod drives the ring plate to move up and down, the ring-shaped in-shell mechanism whole body and the road pier ring-shaped shell move up and down together.
For the spring, when the road pier annular shell moves towards the bottom of the road pier base cylinder, the spring is compressed; under the reset force of the spring, the spring can enable the road pier annular shell to extend out of the road pier base barrel.
The arc that swing guide and a pier base section of thick bamboo were received groove matched with effect is: when the road pier annular shell moves downwards to a position close to the bottom of the road pier base cylinder, the arc-shaped swinging swing guide rail can enter the arc-shaped accommodating groove, and the small-amplitude swinging of the swing guide rail in the arc-shaped accommodating groove continues to enable the road pier annular shell to move downwards until the road pier annular shell cannot move downwards any more. In addition, when the road pier annular shell extends out of the road pier base cylinder, the swing guide rail positioned in the arc-shaped accommodating groove can also come out of the arc-shaped accommodating groove.
The external thread on the threaded rod has a large pitch, the internal thread in the threaded ring sleeve has a large pitch, and the radian of the arc swinging groove is between 2 pi/3 and pi; the design is that when the swing guide rail drives the swing plate to do arc-shaped swing around the road pier annular shell in the arc-shaped swing groove, the swing plate swings in an arc shape from 2 pi/3 to pi, so that the threaded rod can be greatly stretched in the road pier base cylinder through the ring disc, the clamping sleeve and the fourth supporting plate under the threaded matching of the threaded rod and the threaded ring sleeve. In addition, the external thread on the threaded rod has a large pitch, and the internal thread in the threaded ring sleeve has a large pitch, so that the threaded rod can move upwards in a rotating mode along with the road pier ring shell in the process that the road pier ring shell extends out of the road pier base barrel.
The two road piers are matched for use, and the road pier base cylinders of the two road piers are required to be placed in two road foundation pits which are symmetrically distributed on a road surface. The central connecting line of the two road pier base cylinders is an A line; when the push plate is not pushed by external force, the push plate is in a vertical state; the angle formed by the axis of the rotating rod and the line A is 60 degrees; at the moment, the spring is not compressed, and the amount of the road pier annular shell extending out of the road pier base barrel reaches the maximum. When the push plate is in a vertical state, the swinging block on the rotating rod is in contact with the side groove surface of the arc-shaped sliding groove in the sliding block.
For convenience of description of the working process of the road pier of the invention, it is assumed that the maximum amount of the road pier ring-shaped shell extending out of the road pier base cylinder is 400 mm, the diameters of the inner tooth surfaces of the first gear ring and the second gear ring are the same, the diameters of the first sun gear and the second sun gear are the same, and the diameter of the first gear ring is 3 times of the diameter of the first sun gear. Then when the first ring gear rotates 60 degrees, the second sun gear will rotate 540 degrees, i.e., 3 revolutions; the second sun wheel drives the threaded rod to rotate for 3 circles, the threaded rod moves downwards for 200 millimeters under the threaded fit of the threaded rod and the threaded ring sleeve, and the threaded rod drives the whole mechanism in the annular shell and the road pier annular shell to move downwards for 200 millimeters together.
When the vehicle width is greater than the distance between two road blocks, the vehicle cannot pass through the road blocks.
Next, the car width is taken as an example to be smaller than the distance between two road blocks.
When the automobile passes between the two road piers, when the automobile is not contacted with any one push plate, any one road pier does not act.
When the car passes between two road blocks, when car and push pedal contact just promoted the push pedal to a push pedal is promoted to the car, a road block work is as an example: when the push plate in a vertical state is pushed by an automobile to move towards the side groove surface of the swing block contacted with the sliding block, the swing block is limited by the side groove surface of the arc-shaped sliding groove, and the push plate drives the swing guide rail to do arc-shaped swing through the rotating rod and the guide block; when the automobile pushes the push plate to swing to be collinear with the line A, the push plate drives the first gear ring to rotate for 60 degrees through the rotating rod, the sliding block, the swing guide rail and the swing plate, and the first gear ring drives the second sun gear to rotate for 540 degrees, namely 3 circles, through the first planetary gear, the first sun gear, the first rotating shaft, the disk, the second gear ring and the second planetary gear; the second sun wheel drives the threaded rod to rotate for 3 circles, the threaded rod moves downwards by 200 mm under the threaded fit of the threaded rod and the threaded ring sleeve, the threaded rod drives the whole mechanism in the annular shell and the road pier annular shell to move downwards by 200 mm together, and the spring is compressed. After the road pier ring-shaped shell descends by 200 mm, the top cover is lower than the chassis of the automobile. After the push plate is pushed by the automobile, the circular shell of the road pier descends, so that when a driver with unskilled driving technique drives the automobile to pass through the road pier, the automobile is likely to collide with the road pier; the descending of the road pier annular shell and the top cover enables the automobile and the road pier to avoid collision, and the automobile and the road pier are protected; although the road pier ring-shaped shell and the top cover may collide with the chassis of the automobile, the body shell of the automobile is prevented from being scratched; the core parts of the chassis are not easy to damage due to the slight collision of the automobile chassis, so the automobile chassis does not need to be repaired in time after the slight collision is generated between the automobile chassis and the road pier annular shell and the top cover, but the integral attractiveness of the automobile is seriously influenced after the automobile body shell is scratched, and the automobile body shell needs to be repaired in time; in conclusion, the descending of the road pier ring-shaped shell and the top cover avoids the possibility that the body shell of the automobile is scratched, thereby reducing the possibility that the automobile needs to be repaired in time.
After the car passes through the road pier, under the restoring force of spring, the spring can make road pier ring type shell move and restore to the throne, and the threaded rod upwards moves and reverse rotation, and then the bull stick can resume original angle.
When two road piers temporarily need not to intercept the car of different car widths, at first the staff makes the push pedal swing to horizontal position, and the staff passes through swing push pedal and bull stick afterwards for the rotatory great angle of first ring gear, the second sun gear drives the rotatory many circles of threaded rod, under the screw-thread fit of threaded rod and thread ring cover, the threaded rod drives the whole and road pier ring type shell of ring type shell internal organ and moves down to road pier base section of thick bamboo barrel bottom together, and the spring is compressed, the upper cover face and the road surface coplane of top cap this moment. In the swinging process of the push plate and the rotating rod, the guide rail generates arc-shaped swinging, when the road pier annular shell moves downwards to a position close to the bottom of the road pier base barrel, the swinging guide rail of the arc-shaped swinging can enter the arc-shaped accommodating groove, and the small-amplitude swinging of the swinging guide rail in the arc-shaped accommodating groove continuously enables the road pier annular shell to move downwards until the road pier annular shell can not move downwards any more. When the upper cover surface of the top cover is coplanar with the road surface, the sliding block is positioned at the top of the swing guide rail, so that the horizontal push plate can be placed on the horizontal road surface.
And then, the top cover is pressed by the staff through the heavy iron plate, so that the road pier annular shell is prevented from extending out of the road pier base cylinder. When the road pier ring-shaped shell needs to extend out of the road pier base barrel, a worker moves away the heavy iron plate, the spring can enable the road pier ring-shaped shell to move and reset under the reset force of the spring, the threaded rod moves upwards and rotates reversely, and then the rotating rod can restore to the original angle.
Compared with the traditional road pier technology, the transmission relation between the first gear ring and the second sun gear can ensure that the second sun gear can drive the threaded rod to rotate for multiple circles under the condition that the first gear ring rotates for a certain angle, so that the threaded rod can axially move up and down greatly, and the requirement of greatly reducing the road pier annular shell is met. After the push plate is pushed by the automobile, the road pier annular shell and the top cover can descend, so that the collision between the automobile and the road pier is avoided, and the automobile and the road pier are protected. In addition, the road pier is not required to be used, and the road pier annular shell and the top cover can be pressed into the road pier base barrel. The invention has simple structure and better use effect.

According to the invention, the threaded rod 5 can drive the ring disc 17 to rotate in the cutting sleeve 18, and the threaded rod 5 can move up and down and can also drive the road pier annular shell 2 to move up and down in the road pier base barrel 1 through the ring disc 17, the cutting sleeve 18 and the fourth supporting plate 19. The fourth supporting plate 19 drives the second planetary gear 31 to move up and down through the second fixed shaft 32; the pier ring-shaped shell 2 can drive the second gear ring 30 to move up and down through the second supporting plate 29 and the second fixing ring 28; the road pier annular shell 2 can drive the first planetary gear 23 to move up and down through the third support plate 20 and the first fixed shaft 24; the pier ring-shaped shell 2 can drive the first gear ring 13 to move up and down through the first supporting plate 21 and the first fixing ring 22; the first gear ring 13 can drive the swing guide rail 6 to move up and down through the swing plate 12. In a word, the cutting sleeve 18, the fourth supporting plate 19, the second fixed shaft 32, the second planetary gear 31, the second sun gear 33, the second gear ring 30, the disk 34, the second fixed ring 28, the second supporting plate 29, the third supporting plate 20, the first rotating shaft 25, the first fixed shaft 24, the first sun gear 27, the first supporting plate 21, the first fixed ring 22 and the first planetary gear 23 form a ring-shaped in-shell mechanism whole body, and when the threaded rod 5 drives the ring disc 17 to move up and down, the ring-shaped in-shell mechanism whole body moves up and down together with the pier ring-shaped shell 2.
For the spring 8, when the road pier annular shell 2 moves towards the bottom of the road pier base barrel 1, the spring 8 is compressed; under the restoring force of the spring 8, the spring 8 can extend the road block annular shell 2 out of the road block base cylinder 1.
The arc that swing guide 6 and pier base section of thick bamboo 1 were gone up and is accomodate groove 61 matched with effect is: when the road pier annular shell 2 moves downwards to a position close to the bottom of the road pier base barrel 1, the arc-shaped swinging swing guide rail 6 can enter the arc-shaped accommodating groove 61, and the small-amplitude swinging of the swing guide rail 6 in the arc-shaped accommodating groove 61 continues to enable the road pier annular shell 2 to move downwards until the road pier annular shell 2 cannot move downwards any more. In addition, when the road pier ring-shaped casing 2 is extended from the road pier base cylinder 1, the swing guide 6 positioned in the arc-shaped receiving groove 61 can also come out from the arc-shaped receiving groove 61.
The external thread on the threaded rod 5 has a large pitch, the internal thread in the threaded ring sleeve 15 has a large pitch, and the radian of the arc swinging groove 14 is between 2 pi/3 and pi; the design is that when the swing guide rail 6 drives the swing plate 12 to do arc swing around the road pier annular shell 2 in the arc swing groove 14, the swing plate 12 swings in an arc shape from 2 pi/3 to pi, so that the threaded rod 5 can be matched with the thread of the thread ring sleeve 15, and the threaded rod 5 can drive the road pier annular shell 2 to greatly extend and retract in the road pier base barrel 1 through the ring disc 17, the clamping sleeve 18 and the fourth support plate 19. In addition, the external thread on the threaded rod 5 has a large pitch, and the internal thread in the threaded ring sleeve 15 has a large pitch, so that the threaded rod 5 can move upwards in a rotating manner along with the road pier ring shell 2 in the process that the road pier ring shell 2 extends out of the road pier base barrel 1.
The specific implementation mode is as follows: as shown in fig. 19, two road piers are needed to be used in cooperation, and the road pier base cylinders 1 of the two road piers need to be placed in two road foundation pits which are symmetrically distributed on the road surface. The central connecting line of the two road pier base cylinders 1 is A line; when the push plate 3 is not pushed by external force, the push plate 3 is in a vertical state; the angle formed by the axis of the rotating rod 36 and the line A is 60 degrees; at this time, the spring 8 is not compressed, and the amount of the road pier annular shell 2 extending out of the road pier base barrel 1 reaches the maximum. When the push plate 3 is in a vertical state, the swing block 38 on the rotating rod 36 is in contact with the side groove surface of the arc-shaped sliding groove 37 in the sliding block 35.
For convenience of describing the working process of the road block of the present invention, it is assumed that the maximum amount of the road block annular shell 2 protruding out of the road block base cylinder 1 is 400 mm, the diameters of the inner tooth surfaces of the first and second gear rings 13 and 30 are the same, the diameters of the first and second sun gears 27 and 33 are the same, and the diameter of the first gear ring 13 is 3 times the diameter of the first sun gear 27. Then when the first ring gear 13 rotates 60 degrees, the second sun gear 33 will rotate 540 degrees, i.e., 3 revolutions; the second sun gear 33 drives the threaded rod 5 to rotate for 3 circles, under the threaded fit of the threaded rod 5 and the threaded ring sleeve 15, the threaded rod 5 moves downwards for 200 millimeters, and the threaded rod 5 drives the annular shell inner mechanism and the road pier annular shell 2 to move downwards for 200 millimeters together.
When the vehicle width is greater than the distance between two road blocks, the vehicle cannot pass through the road blocks.
Next, the car width is taken as an example to be smaller than the distance between two road blocks.
When the automobile passes between the two road piers, when the automobile is not contacted with any one push plate 3, any one road pier does not act.
When the car passes between two road blocks, the car contacts with push pedal 3 and when promoting push pedal 3 to push pedal 3 is promoted to the car to a road block worker is as an example: when the push plate 3 in a vertical state is pushed by an automobile to move towards the side groove surface of the swing block 38 contacted with the slide block 35, the swing block 38 is limited by the side groove surface of the arc-shaped sliding groove 37, and the push plate 3 drives the swing guide rail 6 to do arc-shaped swing through the rotating rod 36 and the guide block 9; when the automobile pushes the push plate 3 to swing to be collinear with the line A, the push plate 3 drives the first gear ring 13 to rotate for 60 degrees through the rotating rod 36, the sliding block 35, the swing guide rail 6 and the swing plate 12, and the first gear ring 13 drives the second sun gear 33 to rotate for 540 degrees through the first planetary gear 23, the first sun gear 27, the first rotating shaft 25, the disc 34, the second gear ring 30 and the second planetary gear 31, namely 3 circles; the second sun gear 33 drives the threaded rod 5 to rotate for 3 circles, under the threaded fit of the threaded rod 5 and the threaded ring sleeve 15, the threaded rod 5 moves downwards for 200 millimeters, the threaded rod 5 drives the annular shell inner mechanism whole and the road pier annular shell 2 to move downwards for 200 millimeters together, and the spring 8 is compressed. After the road pier ring-shaped shell 2 descends by 200 mm, the top cover 4 is lower than the chassis of the automobile. After the push plate 3 is pushed by the automobile, the road pier annular shell 2 descends, and the design is that when a driver with unskilled driving technique drives the automobile to pass through the road pier, the automobile may collide with the road pier; the descending of the road pier annular shell 2 and the top cover 4 enables the automobile and the road pier to avoid collision, and the automobile and the road pier are protected; although the road pier ring-shaped shell 2 and the roof 4 may collide with the chassis of the automobile, the body shell of the automobile is prevented from being scratched; the core parts of the chassis are not easy to damage due to the slight collision of the automobile chassis, so the automobile chassis does not need to be repaired in time after the slight collision is generated between the automobile chassis and the road pier annular shell 2 and the top cover 4, but the integral attractiveness of the automobile is seriously influenced after the automobile body shell is scratched, and the automobile body shell needs to be repaired in time; in conclusion, the descending of the road pier ring type shell 2 and the top cover 4 avoids the possibility that the body shell of the automobile is scratched, thereby reducing the possibility that the automobile needs to be repaired in time.
After the automobile passes through the road pier, under the reset force of the spring 8, the spring 8 can enable the road pier ring-shaped shell 2 to move and reset, the threaded rod 5 moves upwards and rotates reversely, and then the rotating rod 36 can restore to the original angle.
When two road piers temporarily do not need to intercept automobiles with different car widths, firstly, a worker enables the push plate 3 to swing to a horizontal position, then the worker enables the first gear ring 13 to rotate by a larger angle through swinging the push plate 3 and the rotating rod 36, the second sun gear 33 drives the threaded rod 5 to rotate for a plurality of circles, under the threaded fit of the threaded rod 5 and the threaded ring sleeve 15, the threaded rod 5 drives the annular shell inner mechanism to integrally move downwards to the bottom of the road pier base barrel 1 together with the road pier annular shell 2, the spring 8 is compressed, and the upper cover surface of the top cover 4 is coplanar with the road surface at the moment. In the swinging process of the push plate 3 and the rotating rod 36, the guide rails generate arc-shaped swinging, when the road pier annular shell 2 moves downwards to a position close to the bottom of the road pier base barrel 1, the swinging guide rails 6 of the arc-shaped swinging can enter the arc-shaped accommodating grooves 61, and the small-amplitude swinging of the swinging guide rails 6 in the arc-shaped accommodating grooves 61 continues to enable the road pier annular shell 2 to move downwards until the road pier annular shell 2 cannot move downwards any more. When the upper surface of the top cover 4 is flush with the road surface, the slide block 35 is positioned on the top of the swing rail 6, so that the push plate 3 in a horizontal state can be placed on the horizontal road surface.
Then, the worker presses the top cover 4 with a heavy iron plate to prevent the road pier ring-shaped case 2 from protruding from the road pier base cylinder 1. When the road pier ring-shaped shell 2 needs to extend out of the road pier base barrel 1, a worker removes the heavy iron plate, the spring 8 can enable the road pier ring-shaped shell 2 to move and reset under the reset force of the spring 8, the threaded rod 5 moves upwards and rotates reversely, and then the rotating rod 36 can restore to the original angle.
In conclusion, the invention has the main beneficial effects that: the transmission relation between the first gear ring 13 and the second sun gear 33 can enable the second sun gear 33 to drive the threaded rod 5 to rotate for multiple circles under the condition that the first gear ring 13 rotates for a certain angle, so that the threaded rod 5 can axially move up and down greatly, and the requirement of greatly reducing the road pier ring-shaped shell 2 is met. After the push plate 3 is pushed by the automobile, the road pier annular shell 2 and the top cover 4 can descend, so that the collision between the automobile and the road pier is avoided, and the automobile and the road pier are protected. In addition, the road pier is not required to be used, and the road pier annular shell 2 and the top cover 4 can be pressed into the road pier base cylinder 1. The invention has simple structure and better use effect.
