Technical Field

The utility model belongs to the technical field of mobile contact networks, and particularly relates to a stand column lifting and inclining driving device and a lifting hidden type mobile contact network.

Background

In recent years, the operation links of shunting vehicles are reduced, and the loading and unloading line is constructed according to a through design so as to realize straight-in and straight-out. However, in the electrified section, most loading and unloading lines with aligned in-out conditions are coal trains loaded in open top boxes, when the coal trains are loaded and unloaded by adopting a front crane, the front crane under a fixed contact net cannot work, only a shunting mode that the trains are aligned and connected to a departure line and then are transferred to the loading and unloading line by an internal combustion shunting machine is adopted, the straight-in and straight-out cannot be really realized, the mechanical power is seriously wasted, and shunting personnel (at least 6 persons in each station) are required to be equipped for the work, so the efficiency is low. At present, a foreign mobile contact system adopts a rigid form, and the rigid mobile contact system is only suitable for being used in a warehouse due to rigid suspension, weather, temperature difference and the like, and has high manufacturing cost, large maintenance amount and high failure rate; the domestic movable contact net has two types of rigidity and flexibility, the flexible movable contact net is in a state of withdrawing and releasing a carrier cable and a contact line, and the flexible movable contact net is close to the contact net on the existing line in structure, so that the flexible movable contact net is convenient to maintain, low in manufacturing cost, low in failure rate and easy to maintain; the defects are that the carrier cable and the contact line are often close to the vehicle body due to construction and thermal expansion and cold contraction, and the influence on loading and unloading is huge when large goods or gantry cranes are used for operation.

The freight loading and unloading station of the electrified railway adopts a mobile contact network to provide electric drive for the freight train, and when the mobile contact network is positioned at a working position, namely the contact line is positioned above a rail, the freight train can be driven in or driven out; after the train enters the station, the contact line is moved to the side of the railway by moving the contact line, and the space above the railway is allowed to carry out loading and unloading or overhauling operation. The existing mobile contact net swings at the side of a railway, a left stand column and a right stand column are positioned at one side of the railway, the distance between a cantilever swinging to the side of the railway and the upper part of a railway center is about 3 to 4 meters, the stand column of the mobile contact net is closer to the railway, when a freight train carries out hoisting operation, the safe distance between the operation process of hoisting equipment and the cantilever needs to be considered, a catenary cable and a contact wire are easily touched, potential safety hazards exist, and in the hoisting operation, the vertical stand column is blocked at one side of the railway, and the gantry crane loading and unloading operation is not convenient. Because the upright column and the cantilever are positioned at high positions, the vertical upright column is blocked at one side of a railway during hoisting operation, so that the gantry crane is inconvenient to assemble and disassemble. The efficiency and safety of freight handling operation are seriously affected, and the lifting contact net needs to be researched urgently to realize that the contact net is lifted to the position below the bottom of a car body after being transversely moved.

The other end of the pushing piece 10 directly or indirectly acts on the pull rope 12; in the process that the pull rope 12 moves to drive the other end of the pushing piece 10 to be far away from the upright post 1, the upright post 1 gradually tilts; in the process that the pull rope 12 moves to drive the other end of the pushing piece 10 to approach the upright post 1, the upright post 1 is gradually vertical.

In order to ensure the smoothness of movement, a moving mechanism 13 is further arranged in the embodiment, and the other end of the pushing member 10 directly or indirectly acts on the moving mechanism 13; in the process that the pull rope 12 moves to drive the moving mechanism 13 to be far away from the upright post 1, the upright post 1 gradually tilts; in the process that the pull rope 12 moves to drive the moving mechanism 13 to be close to the upright post 1, the upright post 1 is gradually vertical. A sliding dolly is one embodiment of the moving mechanism 13.

In order to ensure smooth and smooth movement of the moving mechanism 13, in this embodiment, a sliding rail 14 is further provided, the moving mechanism 13 is disposed on the sliding rail 14, and the movement of the pulling rope drives the moving mechanism 13 to move on the sliding rail 14.

As a preferred embodiment with important characteristics, if the pull cord is fixed directly or indirectly to the other end of the pushing member 10, there may be a drawback that when one of the pushing members 10 is in place and the other pushing member 10 is not in place, the column 1 in the whole mobile catenary will topple or not be in place vertically.

Considering that a pull rope needs to push a plurality of upright posts 1 to ascend and descend, the other end of the pushing piece 10 corresponding to each upright post 1 needs to be directly or indirectly fixed on the pull rope. The whole pulling effect is influenced by the clamping stagnation phenomenon at a certain point position.

In order to solve this problem, a force transmission mechanism 15 is provided, and the force transmission mechanism 15 is used for transmitting the pulling force of the movement of the pulling rope to the moving mechanism 13 to drive the moving mechanism 13 to move. The elastic pushing piece 10 is used for force transmission, and even if clamping stagnation occurs at a certain point, the pull rope can be further pulled, so that the lifting of the middle upright post 1 of the overall mobile contact network is not influenced.

The force transmission mechanism 15 includes an elastic pushing member, one end of the elastic pushing member is disposed on the pulling rope, the pulling rope moves to push or pull the elastic pushing member, and the formed pushing force or pulling force acts on the moving mechanism 13 directly or indirectly through the elastic pushing member. The applicant of the force transmission mechanism 15 has filed an application for additional protection, which will not be described in detail herein.

As a preferred embodiment, the device further comprises a sleeve 16, the sleeve is arranged on the moving mechanism 13, the pulling rope is arranged in the sleeve 16 in a penetrating manner, one end of the elastic pushing member is arranged on the pulling rope, a stopper for bearing the acting force of the other end of the elastic pushing member is arranged in the sleeve 16, the pulling rope moves to push or pull the elastic pushing member, and the formed pushing force or pulling force acts on the sleeve 16 directly or indirectly through the elastic pushing member.

As a preferred embodiment, the elastic pushing member in this embodiment may be a spring. The number of the springs can be one or two.

As shown in fig. 7, for example: two springs are arranged in the sleeve 16, and the pull rope is supposed to move towards the left side to push the spring 17 on the left side of the sleeve 16 to compress, the compressed spring transmits force to the sleeve 16, and the sleeve is fixed on a moving structure, so that the other end of the pushing piece 10 connected with the upright post 1 is driven to move towards the left to lift the upright post 1;

in a similar way, the pull rope moves towards the right side, the spring 18 on the right side of the sleeve 16 is pushed to be compressed, the compressed spring transmits force to the sleeve 16, and the sleeve is fixed on the moving structure, so that the other end of the pushing piece 10 connected with the upright post 1 is driven to move rightwards, and the upright post 1 is lowered. The arrangement of the spring is merely an illustration and is not intended to limit the claims.

As shown in fig. 6, in order to solve the problem of movement of the pulling rope, the driving structure 11 provided in the present embodiment includes a first driving unit 111 and a second driving unit 112; the first driving unit 111 and the second driving unit 112 respectively directly or indirectly act on both ends of the rope to drive the rope to move. In this embodiment, the first driving unit 111 is a dragging motor, and the second driving unit 112 is a weight; or both the first driving unit 111 and the second driving unit 112 are drag motors. The movement of the pull rope is driven by the combined action of the first and second driving units, and the pull rope moves through one end of the pushing piece 10 which directly or indirectly acts force through the force transmission mechanism 15, so that the pushing movement is realized, and the upright post 1 is pushed or pulled to change the state.

It should be noted that the present embodiment provides a force acting on the long arm of the upright 1, but of course the above-mentioned manner of pulling the pushing member 10 by the pulling rope may also act on the short arm.

Of course, it is to be particularly emphasized here that the second body part 6 is an optional component, without a second body part, and that this solution drive is fully possible. The driving scheme with the second body portion 6 is more stable, and the rising and falling of the upright post 1 are more stable by changing the structural form of the upright post 1 in the embodiment. The first body portion 5, the pivot point, and the second body portion 6 in the present embodiment may be understood as a lever structure; in the absence of the second body portion 6, during the tilting or vertical movement of the upright 1, there is a variation in the centre of gravity of the upright 1, the weight of which is either gradually increasing or gradually decreasing; the sudden weight of this part needs to be borne by an external drive mechanism, but in the case of pulling the entire upright 1 with a pull rope or pulling the pushing member 10 with a pull rope, the sudden weight return causes an additional workload on the pull rope.

It is further described that, in the process of dumping the upright post 1 in the related art, the gravity center of the upright post 1 changes suddenly, and the gravity of the upright post 1 acting on the push-pull device increases gradually from zero in the process of dumping, which causes the push-pull device to bear the sudden work load. On the other hand, the upright post 1 is used for driving the carrier cable and/or the contact line to lift, which causes the toppling process of the upright post 1 to be unstable.

To this end, a preferred embodiment is provided wherein a second body portion 6 may be added, the second body portion 6 being either integrally formed with the first body portion 5 or removably attached thereto. The second body portion 6 acts primarily to balance the lever and reduce sudden changes in the weight of the column 1 as it topples or is erected.

Through the adjustment of the mechanical structure form of the upright post 1, the workload of the push-pull device caused by the sudden change of the gravity center in the process of toppling or erecting the upright post 1 is reduced. The problem of unstable driving caused by sudden load change is avoided. The net effect is that the column 1 can be tilted or erected with a small external driving force.

As shown in fig. 8, of course, for further adaptation, a counterweight structure 19 is also provided in this embodiment, said counterweight structure 19 being provided directly or indirectly on the second body portion 6 of the upright 1. The weight structure 19 may be integrated with the second body portion 6, or the weight structure 19 may be suspended from the second body portion 6 by a rope, and the weight structure 19 may be composed of detachable weight blocks.

Again, it should be expanded that, in the present embodiment, a counterweight structure 19 is further included, and the counterweight structure 19 is directly or indirectly disposed on the second body portion 6 of the upright 1. One way is to add weight to the second body portion 6 as a counterweight structure 19; the other way is to hang a weight on the basis of the first way or on the second body part 6. The aim is that the situation of sudden change of the original gravity strength is overcome through the matching of the counterweight structure 19 and the rotating fulcrum structure 3 in the process of toppling the upright post 1, and the lifting is more stable; meanwhile, the vertical column 1 can be driven to lift only by a small force by adopting the lever structure. Therefore, one driving motor (winch) can drive more columns 1, and the column 1 lifting and inclining driving device provided by the utility model can be used for a long-distance moving contact net.

It should be added that the driving mechanism in this embodiment includes a first driving unit 111 and a second driving unit 112; the first driving unit 111 and the second driving unit 112 respectively directly or indirectly act on both ends of the rope to drive the rope to move.

Further, in the first scheme, the first driving unit 111 is a dragging motor, and the second driving unit 112 is a weight. In the second scheme, the first driving unit and the second driving unit are both dragging motors; one motor rotates forwards and the other motor rotates backwards to drive the pull rope to move. It is not the point of protection of the present invention as to how the cantilever turns the messenger and contact line over or to the side of the railway. The feasible mode is that a motor is used at one end of the movable contact net, a balance weight is used at the other end of the movable contact net, and the wrist arm is driven to rotate above the railway or to the side of the railway in a matching mode of the motor and the balance weight.

In the prior art, the cantilever support structure 20 is rotatably mounted on the upright 1, and the cantilever support structure 20 swings to the upper side of the railway (working position) or swings to the side of the railway (non-working position). In the present invention, the column 1 is required to be tipped. The pouring benefits are: drive whole removal contact and descend to ground, give out the top space, be favorable to goods handling, provide great goods handling space, reduce original goods handling in-process hoisting equipment simultaneously and touch the removal contact net, for example touch the contact wire, the damage is caused to cantilever structure etc.. There is a great advantage in dumping the column 1. However, no specific implementation scheme is provided in the prior art, so the utility model provides a novel hidden mobile overhead line system,

the biggest problem in the prior art is that the wrist-arm structure is required to be inclined at a corresponding angle in the process of inclining the upright post 1. Therefore, the most important problems to be solved are: during the process of the column 1 falling, the wrist-arm structure is relatively kept not to rotate, so that the carrier cable and/or the contact line are basically kept parallel to the ground during the process of ascending or descending. For this purpose, a new structure is needed, such as the first shaft 21 added in the present invention, and the first shaft 21 is arranged on the upright 1. In the process that the upright post 1 is inclined, the upright post 1 is rotatably connected with the first shaft 21, the tension of the catenary and the contact line acts on the cantilever support structure 20, which is equivalent to providing balance tension for the cantilever support structure 20 from two ends, the root part of the cantilever support structure 20 is directly or indirectly arranged on the first shaft 21, and the upright post 1 is rotatably connected with the first shaft 21, so that the cantilever support structure 20 cannot incline in the process that the upright post 1 is inclined or vertical.

The utility model can effectively overcome the defects of the prior art, and the upright post is rotationally connected with the first shaft 21 in the process of tilting or erecting the wrist-arm supporting structure 20, so that the upright post can be conveniently tilted or erected, the first shaft 21 per se is not rotated in the process, and all the wrist-arm supporting structures can be kept not to rotate; all the upright posts ascend or descend to drive the carrier cable and/or the contact line to ascend or descend. When the upright post in the movable contact net is inclined or vertical, the working position/non-working position switching driving mechanism of the electric conductor always provides tension for the electric conductor, and the electric conductor with the tension can pull or drag the cantilever supporting structure from another angle. The most important is that the electric conductor can provide electric energy for the freight train when in a working position, and the pantograph can be lifted up to take electricity. When the electric conductor is in a non-working position, even if the wrist arm supporting structure shakes, the influence cannot be caused and can be ignored. In the embodiment, the carrier cable 25 and the contact line 26 keep relatively constant tension; the contact line 26 and the carrier cable 25 cannot be bent due to the turnover of the wrist arm in the movement process; because of the scheme provided by the implementation, the wrist-arm supporting structure cannot be overturned. The situation that the original wrist supporting structure is pulled and deformed is overcome; the contact line 26 of the carrier cable 25 can also be lifted or lowered in a manner of being parallel to the ground; the driving is reliable, the operation is more stable, the stability of the system operation is improved, and the safety guarantee is provided for cargo handling.

By adopting the utility model, the defects of the prior art can be effectively overcome, and the carrier cable and the contact line keep relatively constant tension in the process of toppling or erecting the cantilever support structure 20; the contact line and the carrier cable are not bent in the movement process; the wrist-arm structure has no tensile deformation; the catenary contact line can also be raised or lowered relative to a parallel ground.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and those skilled in the art will include within their scope variations, modifications, substitutions and alterations.
