Description

Technical Field

[0001] This utility model belongs to the field of railway construction technology, specifically relating to lifting equipment used in railway construction. Background Technology

[0002] Rail transport is a mode of land transportation that uses locomotives to pull trains along two parallel rails. Traditionally, it uses steel wheels, but in a broader sense, rail transport also includes non-steel wheeled modes such as maglev trains, cable cars, and ropeways, also known as rail transport. Rails provide an extremely smooth and hard medium on which train wheels roll with minimal friction, making it more comfortable for passengers and saving energy. If properly configured, rail transport can save 50-70% more energy than road transport when carrying the same weight. Furthermore, rails evenly distribute the weight of the train, significantly increasing its carrying capacity.

[0003] During railway construction, there are sometimes procedures involving the lifting and transfer of heavy objects. For example, when transporting materials placed on sleepers between two railway sections, the objects on the sleepers need to be transferred to a rail flatbed trolley, and then the rail flatbed trolley travels along the rails to the target section to complete the transfer.

[0004] However, when dealing with heavy items, the items on the sleepers need to be lifted manually or mechanically to the height of the trolley and then moved onto the trolley, which is cumbersome and inefficient. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a lifting device for railway construction, which solves the problems of cumbersome operation and low efficiency when transferring materials on sleepers using existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The bottom surface of the groove of each roller is always in contact with the top surface of the rail. The hand-cranked lifting structure is fixedly mounted on the base plate and has a handle and a lifting end. When the handle is turned, the lifting end rises.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown, the lifting equipment used in railway construction includes:

[0034] Two lifting mechanisms are provided; one lifting mechanism is movably mounted on a rail. The lifting mechanism includes a base plate 1, a set of rollers 12, and a hand-cranked lifting structure. The set of rollers 12 includes two rollers 12. The set of rollers 12 are rotatably mounted on the bottom surface of the base plate 1. Each roller 12 has a groove that is connected end to end on its wheel surface. The bottom surface of the groove of each roller 12 is always in contact with the top surface of the rail. The hand-cranked lifting structure is fixedly mounted on the base plate 1. The hand-cranked lifting structure has a handle 4 and a lifting end. When the handle 4 is rotated, the lifting end rises.

[0035] Load-bearing rod 8; both ends of the load-bearing rod 8 are connected to the lifting ends of the two lifting mechanisms respectively;

[0036] The hoisting rope 9 is fixedly connected to the load-bearing rod 8 at one end, and the other end of the hoisting rope 9 is used to tie the object to be lifted.

[0037] In this embodiment, the lifting device of this application can move on the rail via rollers 12. This application is provided with a lifting mechanism and a load-bearing rod 8. The hoisting rope 9 is tied to the object to be transferred on the sleeper. When the handles 4 of the lifting mechanism on both sides of the load-bearing rod 8 are rotated, the two lifting ends rise, and the load-bearing rod 8 also rises. At this time, the hoisting rope 9 on the load-bearing rod 8 pulls up the object to be lifted on the sleeper, completing the lifting operation. Then, the application can be driven to the target railway section to complete the material transfer operation on the sleeper.

[0038] Using this application, the material on the sleeper only needs to be slightly lifted off the sleeper surface for transportation. There is no need to lift the material to the height of the rail trolley and transfer it. The operation is simple, saves working time, and improves work efficiency.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 As shown, a lifting mechanism includes:

[0041] Fixed rod 2; the bottom end of fixed rod 2 is fixedly installed on base plate 1;

[0042] First rotating shaft 3; the first end of the first rotating shaft 3 is fixedly installed on the top of the fixed rod 2;

[0043] Connecting plate 5; A first through hole is provided in the middle section of the connecting plate 5. The connecting plate 5 is rotatably mounted on the second end of the first rotating shaft 3 through the first through hole. The handle 4 is fixedly connected to one end of the connecting rod.

[0044] Two second rotating shafts; the first ends of both second rotating shafts are fixedly installed on both ends of the connecting plate 5;

[0045] Two locking blocks 10; the locking blocks 10 are arc-shaped, and each of the first ends of the two locking blocks 10 is provided with a second through hole. The two locking blocks 10 are rotatably mounted on the two second rotating shafts through their own second through holes.

[0046] Slide 11; Slide 11 is vertically installed on base plate 1, the bottom end of slide 11 is fixedly connected to the top surface of base plate 1, and the slotted surface of slide 11 points towards fixed rod 2;

[0047] Rack; The rack has a double-layer structure. The first layer 7 of the rack is slidably set in the slide groove 11, and the second layer 6 of the rack is set outside the slide groove 11. Both sides of the second layer 6 of the rack are provided with multiple vertically arranged oblique teeth pointing towards the ground.

[0048] The elastic element has two ends respectively set on the two locking blocks 10. The elastic element continuously applies a pulling force to the two locking blocks 10. The pulling force on each locking block 10 is directed towards the other locking block 10. In the initial state, the second end of one locking block 10 is pressed into contact with two oblique teeth on one side of the second layer of the rack through the elastic element.

[0049] In this embodiment, when the handle 4 is pressed, the handle 4 drives the connecting plate 5 to rotate along the first rotating shaft 3. Let the end near the handle 4 be the first end of the connecting plate 5 and the other end be the second end. At this time, the first end of the connecting plate 5 moves downward and the second end of the connecting plate 5 moves upward. At the same time, the second end of the locking block 10 at the first end of the connecting plate 5 is pressed into contact with the inclined surface of a helical tooth. Since the first end of the locking block 10 is rotatable, the second end of the locking block 10 near the handle 4 slides outward along the inclined surface under pressure. After it is released from the pressure with the helical tooth, it falls into the gap between the next helical tooth and the helical tooth through the pulling force of the elastic element. At the same time, the second end of the locking block 10 at the second end of the connecting plate 5 rises with the connecting plate 5 and pushes the rack upward, and then lifts the handle 4. At this time, the locking block 10 at the second end of the connecting plate 5 and the locking block 10 at the first end of the connecting plate 5 exchange working processes. By repeating the above steps, the material on the sleeper can be gradually lifted, and the lifting height is controllable.

[0050] Example 3

[0051] The difference between this embodiment and Embodiment 2 is that, as Figure 2 As shown, the elastic element includes:

[0052] Two mounting rods 13; the two mounting rods 13 are respectively fixedly installed on the two clips 10;

[0053] Tension spring 14; both ends of tension spring 14 are fixedly connected to two mounting rods 13 respectively.

[0054] Example 4

[0055] The difference between this embodiment and Embodiment 2 is that, as Figure 1 As shown, the two ends of the load-bearing rod 8 are respectively hinged to the top of the first layer 7 of the two racks. After hinge, the load-bearing rod 8 can rotate at a certain angle in the vertical direction.

[0056] In this embodiment, to avoid the phenomenon of the lifting mechanism getting stuck and the load-bearing rod 8 bending due to inconsistent lifting speeds of the two lifting mechanisms, the two ends of the load-bearing rod 8 are connected to the top of the first layer 7 of the two racks in a hinged manner.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
