Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Example one
Referring to fig. 1 to 3, the present invention discloses a supporting device for a forklift, including:
the fixed supporting leg 100 includes a fixed supporting portion 110 parallel to a horizontal plane and a sliding rail 120 vertically and fixedly connected to the fixed supporting portion 110, the fixed supporting portion 110 includes two fixed supporting rods 111 parallel to each other and perpendicular to the sliding rail 120, the sliding rail 120 includes a first sliding rail 121 and a second sliding rail 122, and the second sliding rail 122 can slide along the first sliding rail 121; the first slide rail 121 comprises two first guide rails parallel to each other, and the second slide rail 122 comprises two second guide rails parallel to each other;
the sliding support leg 200 is slidably connected to the second slide rail 122, the sliding support leg 200 includes a sliding support portion 220 and a sliding portion 210 vertically fixedly connected to the sliding support portion 220, the sliding portion 210 is slidably connected to the second slide rail 122, and the sliding support portion 220 includes two sliding support rods 221 parallel to each other and perpendicular to the slide rail 120; the sliding support part 220 and the fixed support part 110 are located on the same side of the slide rail 120;
the hydraulic rod 300 is disposed between the two first guide rails and is parallel to the first guide rails, and the hydraulic rod 300 stretches and retracts to drive the second slide rail 122 to slide along the first slide rail 121.
When viewed from the side, the whole fixed supporting leg 100 is L-shaped, i.e. the fixed supporting portion 110 is perpendicular to the sliding rail 120; the slide rail 120 is divided into a first slide rail 121 and a second slide rail 122, and the second slide rail 122 slides along the first slide rail 121, and the sliding support foot 200 can slide along the second slide rail 122. That is, in the present embodiment, there are two segments slidably disposed, and the hydraulic rod 300 is pressed against the second slide rail 122, so that the second slide rail 122 slides along the first slide rail 121; meanwhile, the hydraulic rod 300 can also drive the sliding support leg 200 to slide along the second slide rail 122. Therefore, in the embodiment, two displacement stages are provided, so that the height of the sliding support foot 200 can be further increased, and meanwhile, compared with the case where only one displacement stage is provided, the structural strength is higher.
A rotatable rotating block 520 is respectively arranged at the preset height of the two first guide rails; a bump 510 is respectively fixed at the bottom ends of the two second guide rails; when the second sliding rail 122 slides upwards and the protrusion 510 slides to a predetermined height, the protrusion 510 contacts with the rotation block 520 and drives the rotation block 520 to rotate until the protrusion 510 is separated from the rotation block 520, and when the second sliding rail 122 slides downwards and the protrusion 510 slides to the predetermined height, the protrusion 510 contacts with the rotation block 520 and drives the rotation block 520 to rotate in the other direction until the protrusion 510 is separated from the rotation block 520.
As shown in fig. 1 and fig. 3, as the second slide rail 122 slides along the first slide rail 121, when the protrusion 510 passes through a predetermined height, the rotation block 520 is driven to rotate by a small angle, and the rotation angle can be adjusted as required; when the protrusion 510 slides from bottom to top, the rotation block 520 is driven to rotate counterclockwise (or clockwise), and when the protrusion 510 slides from top to bottom, the rotation block 520 is driven to rotate clockwise (or counterclockwise).
A fixed sleeve 540 is fixed at the bottom end of each of the two first guide rails, a wheel 560 is connected to the lower end of each fixed sleeve 540, a lifting rod 550 penetrates through the fixed sleeve 540, the lifting rod 550 can slide up and down relative to the slide rail 120, and the lifting rod 550 can lift or lower the slide rail 120 relative to the up-and-down movement of the slide rail 120.
Further, the wheel 560 is disposed at the bottom end of the first sliding rail 121, and in normal operation, the wheel 560 is lifted off the ground, and as the rotating block 520 rotates, when the wheel 560 descends to contact with a working surface (e.g., the ground), the first sliding rail 121 continues to apply a downward force to the wheel 560, which is equivalent to an upward force to the first sliding rail 121, and the direction of the force is opposite to that of the upward force. It can thus be derived: since the vertical height of the lifting rod 550 to the ground is not changed, when the lifting rod 550 moves up and down relative to the slide rail 120, the first slide rail 121 is actually lowered or raised relative to the ground.
A hinge rod 530 is further arranged between the rotating block 520 and the lifting rod 550, one end of the hinge rod 530 is hinged with the rotating block 520, and the other end of the hinge rod 530 is hinged with the lifting rod 550; when the rotating block 520 rotates, the lifting rod 550 may be driven to move up and down relative to the sliding rail 120 to lift or lower the sliding rail 120.
Still further, the purpose of the hinge lever 530 is to: the torque on the rotating block 520 is converted to a torque on the lifting rod 550 in a straight line.
The specific implementation steps and principles of the above embodiment are as follows: when the second slide rail 122 drives the protrusion 510 to ascend or descend to a preset height, the rotation block 520 may be driven to rotate clockwise or counterclockwise, so that the hinge rod 530 drives the lifting rod 550 to move downward or upward relative to the first slide rail 121, thereby realizing that the first slide rail 121 is lifted or lowered relative to the ground, and the first slide rail 121 drives the whole supporting leg device to further drive the chassis of the forklift to be lifted or lowered relative to the ground.
The advantages of such an arrangement are: when the forklift passes through a certain turning slope or a road with a larger slope, the wheels 560 can be contacted with the ground, and the possibility of rollover of the forklift can be greatly reduced by the stress of the wheels 560; when the forklift passes through some rugged road surfaces, the whole forklift can be lifted by applying a downward force to the wheels 560, so that the ground clearance of the chassis is higher, the chassis is not scratched or blocked by the rugged road surfaces when passing through the ground clearance, and the passing performance of the forklift is improved.
When it is pointed out that, the preset height can be calibrated and set differently according to different requirements.
Two limiting columns 570 are arranged on the first guide rails, and the two limiting columns 570 are used for limiting the rotation of the rotating block 520 in two opposite directions respectively.
As shown in fig. 3, the limiting column 570 is provided to limit the rotation of the rotation block 520, and it is easy to derive: when the rotating block 520 abuts against the two limiting posts 570, the hinge rod 530 is located at different sides of the axis where the lifting rod 550 is located; that is, when the rotating block 520 abuts against any one of the limiting posts 570, the hinge rod 530 tightly abuts against the rotating block 520 and the limiting post 570 under the gravity of the whole device, and the state of the device is not changed without human intervention.
One end of each fixed support rod 111, which is far away from the slide rail 120, is provided with a wheel set 112, and the wheel set 112 protrudes out of the surface of the fixed support rod 111; one end of each of the sliding support rods 221, which is far away from the slide rail 120, is provided with a through hole 222 for allowing the wheel set 112.
The sliding support 220 is fixedly connected with two sliding blocks 211, a plurality of pulleys 213 are arranged between each sliding block 211 and one of the second sliding rails 122, and the sliding blocks 211 can slide along the second sliding rails 122.
At least one reinforcing block 212 is arranged between the two sliding blocks 211, and the reinforcing block 212 is perpendicular to the sliding blocks 211 and the sliding support part 220.
The sliding support further comprises a control assembly 400, which is disposed at the bottom end of the sliding rail 120 and at a side far away from the fixed support portion 110, wherein the control assembly 400 is used for controlling the sliding of the second sliding rail 122 relative to the first sliding rail 121 and the sliding of the sliding support foot 200 relative to the second sliding rail 122.
Example two
This embodiment is substantially the same as the first embodiment, with the following differences:
by utilizing the structural characteristics that the lifting rod 550 moves up and down along with the rotation of the rotating block 520, the lifting rod 550 can be used as a brake rod, the wheel 560 is always in contact with the ground, the wheel 560 is fixedly connected with the slide rail 120, and the lifting rod 550 can be abutted against the surface of the wheel 560 through the fixed sleeve 540.
Specifically, when the lifting rod 550 moves downward, the lower end of the lifting rod 550 abuts against the surface of the wheel 560, so that the wheel 560 can be locked, and when the lifting rod 550 moves upward, the lower end of the lifting rod 550 disengages from the surface of the wheel 560, so that the wheel 560 can be unlocked.
Those skilled in the art can think that the lower end of the lifting rod 550 is additionally provided with a wear-resistant material and a material with a large friction coefficient (such as brake shoe, etc.), so that the braking effect is better, and the modifications are within the protection scope of the present embodiment.
The purpose of this is to standardize the use of the fork truck: that is, when the height of the second slide rail 122 rises to a certain height, the center of gravity thereof is high, and if the second slide rail continues to move, accidents such as rollover easily occur. Therefore, for safety, a structure such as a rotating block 520 may be provided at a preset safety height, and when the second slide rail 122 is raised to exceed the safety height, the wheel 560 is locked, and when the second slide rail 122 is lowered to be within the safety height, the wheel 560 is unlocked. The safety of the use of the device is ensured, and the occurrence of accidents is avoided.
When it is pointed out that, the safety height or the preset height can be calibrated and set differently according to different requirements.
EXAMPLE III
This embodiment is substantially the same as the first embodiment, with the following differences:
the alarm is arranged at the preset height, when the second sliding rail 122 rises to the preset height, the alarm can be alarmed through the rotating block 520, an operator is reminded that the second sliding rail 122 exceeds the safe height, and when the second sliding rail 122 falls to the safe height range, the alarm can be relieved.
The advantages of such an arrangement are: the lifting height of the operator can be reminded whether to be within the safe height range, so that the operation safety is ensured, and the occurrence of accidents is reduced.
When it is pointed out that, the safety height or the preset height can be calibrated and set differently according to different requirements.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
