Description

Technical Field

[0001] This utility model relates to the field of railway track slab construction technology, and in particular to a construction hoist for railway track slabs. Background Technology

[0002] Railway track slabs are structural components used to support railway tracks, typically made of concrete or steel. With the development of railway transportation, especially the rapid construction of high-speed railways and urban rail transit, the demand for railway track slab construction is increasing. As a crucial component of railway tracks, the installation accuracy and construction efficiency of railway track slabs directly affect the safety and operational efficiency of the railway. Lifting is required during construction; therefore, a construction lifting tool for railway track slabs is needed.

[0003] Traditional construction lifting equipment is usually designed for specific specifications of track slabs. This means that when lifting track slabs of different specifications, the construction team must change different lifting equipment, which increases the overall construction cost. Moreover, frequent equipment changes on the construction site affect the continuity and efficiency of construction. During the construction of track slabs, it is sometimes necessary to adjust the angle of the track slabs to ensure their installation accuracy. However, traditional construction lifting equipment usually does not have the function of adjusting the angle of the track slabs, making it difficult to ensure the correct positioning of the track slabs. This may lead to improper installation of the track slabs and affect the subsequent laying of the track. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction hoisting tool for railway track slabs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction hoist for railway track slabs includes a rectangular frame. Rollers are installed at the four corners of the bottom of the rectangular frame. A connecting plate is provided at the top of the rectangular frame. Lifting mechanisms for raising and lowering the connecting plate are provided at both ends of the top of the rectangular frame. A rotating shaft is passed through the top of the connecting plate. A disc is fixed to the bottom end of the rotating shaft. A rotating mechanism for rotating the rotating shaft is provided at the top of the connecting plate. Two L-shaped plates are provided at the bottom of the disc. A first moving mechanism for moving the two L-shaped plates is provided at the bottom of the disc. Through holes are formed on the sidewalls of both L-shaped plates, and stops are provided on the sidewalls of both through holes. The L-shaped plate is equipped with a second moving mechanism at its top for moving two stops. During use, the distance between the two L-shaped plates is adjusted by the first moving mechanism, and the two stops are moved by the two second moving mechanisms. This allows for clamping and fixing of track plates of different specifications without the need to change equipment, reducing construction costs and improving construction flexibility. The rotating mechanism drives the disc to rotate, which in turn drives the two L-shaped plates to rotate, allowing for adjustment of the installation angle of the track plate. This ensures precise alignment between the track plate and the installation position, thereby improving installation accuracy and preventing subsequent track laying from being affected.

[0007] Preferably, the lifting mechanism includes a mounting plate fixed to the outer wall of one end of a rectangular frame. A connecting seat is fixed to the top of the mounting plate. A sliding groove is formed on the inner side wall of the connecting seat. A lead screw is provided inside the sliding groove. A first lead screw nut is slidably connected to the side wall of the sliding groove. The first lead screw nut is sleeved on the side wall of the lead screw and is adapted to the lead screw. The first lead screw nut is fixed to one end of the connecting plate. A first motor is fixed to the top of the connecting seat. The output shaft of the first motor is fixed to the lead screw. The two first motors drive the two lead screws to rotate simultaneously. The two first lead screw nuts drive the connecting plate to move downward. The downward movement of the connecting plate drives the disc to move downward, which in turn drives the two L-shaped plates to move downward.

[0008] Preferably, the first moving mechanism includes two second support plates, the inner walls of which are rotatably connected to the same bidirectional lead screw, and the inner walls of which are fixed to the same sliding rod. Two second lead screw nuts are symmetrically sleeved on the sidewalls of the bidirectional lead screw, both of which are adapted to the bidirectional lead screw and slidably connected to the sliding rod. The two second lead screw nuts are respectively fixed to two L-shaped plates. A third motor is fixed to the outer wall of one of the second support plates, and the output shaft of the third motor is fixed to the bidirectional lead screw. The second moving mechanism includes two third support plates, both of which are rotatably connected to the same bidirectional lead screw. Fixed to the top of one of the L-shaped plates, the two third support plates have the same L-shaped plate running through their side walls, and the output end of the hydraulic push rod and the stop block are fixed. The third motor drives the bidirectional lead screw to rotate, and the sliding rod makes the two second lead screw nuts move closer or further apart, thereby causing the two L-shaped plates to move closer or further apart. By adjusting the distance between the two L-shaped plates, track plates of different specifications can be clamped and fixed without changing equipment, reducing construction costs, saving time, and improving work efficiency. The two hydraulic push rods drive the two stops to move closer together until both are located at the bottom of the track plate, thus completing the fixing of the track plate.

[0009] Preferably, the rotating mechanism includes a worm gear, which is sleeved on the side wall of the other end of the rotating shaft. Two first support plates are symmetrically fixed to the top of the connecting plate. The inner side walls of the two first support plates are rotatably connected to the same worm, and the worm and the worm gear mesh. A second motor is fixed to the outer side wall of one of the first support plates, and the output shaft of the second motor is fixed to the worm. The second motor drives the worm to rotate, which in turn drives the rotating shaft to rotate, thereby driving the disc to rotate. This allows for angle adjustment of the track plate. After adjustment, two hydraulic push rods are driven to move two stops in the opposite direction, causing the two stops to disengage from the track plate. At this point, the track plate falls precisely into the installation position.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, this device adjusts the distance between the two L-shaped plates through the first moving mechanism, and in conjunction with the two second moving mechanisms, drives the two stops to move, thereby clamping and fixing track plates of different specifications without the need to replace equipment, reducing construction costs and improving construction flexibility.

[0012] 2. The rotating mechanism drives the disc to rotate, which in turn drives the two L-shaped plates to rotate. This allows for adjustment of the installation angle of the track plates, ensuring precise alignment between the track plates and the installation position. This improves installation accuracy and prevents subsequent track laying from being affected. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 - Figure 5A construction hoist for railway track slabs includes a rectangular frame 1, with rollers 2 installed at the four corners of the bottom of the rectangular frame 1. A connecting plate 6 is provided at the top of the rectangular frame 1, and lifting mechanisms for raising and lowering the connecting plate 6 are provided at both ends of the top of the rectangular frame 1. A rotating shaft 14 is provided through the top of the connecting plate 6, and a disc 7 is fixed at the bottom end of the rotating shaft 14. A rotating mechanism for rotating the rotating shaft 14 is provided at the top of the connecting plate 6. Two L-shaped plates 21 are provided at the bottom of the disc 7, and a first moving mechanism for moving the two L-shaped plates 21 is provided at the bottom of the disc 7. Through holes 22 are provided on the side walls of the two L-shaped plates 21, and stops 25 are provided on the side walls of the two through holes 22. Each L-shaped plate 21 has a second moving mechanism at its top for moving two stops 25. During use, the distance between the two L-shaped plates 21 is adjusted by the first moving mechanism, and the two stops 25 are moved by the two second moving mechanisms. This allows for clamping and fixing of track plates of different specifications without the need to change equipment, reducing construction costs and improving construction flexibility. The rotating mechanism drives the disc 7 to rotate, which in turn drives the two L-shaped plates 21 to rotate. This allows for adjustment of the installation angle of the track plate, ensuring precise alignment between the track plate and the installation position, thereby improving installation accuracy and preventing subsequent track laying from being affected.

[0021] Furthermore, the lifting mechanism includes a mounting plate 3, which is fixed to the outer wall of one end of the rectangular frame 1. A connecting seat 4 is fixed to the top of the mounting plate 3. A sliding groove 8 is provided on the inner side wall of the connecting seat 4. A lead screw 9 is provided inside the sliding groove 8. A first lead screw nut 10 is slidably connected to the side wall of the sliding groove 8. The first lead screw nut 10 is sleeved on the side wall of the lead screw 9 and is adapted to the lead screw 9. The first lead screw nut 10 is fixed to one end of the connecting plate 6. A first motor 5 is fixed to the top of the connecting seat 4. The output shaft of the first motor 5 is fixed to the lead screw 9. The two first motors 5 drive the two lead screws 9 to rotate simultaneously. The two first lead screw nuts 10 drive the connecting plate 6 to move downward. The downward movement of the connecting plate 6 drives the disc 7 to move downward, which in turn drives the two L-shaped plates 21 to move downward.

[0022] Furthermore, the first moving mechanism includes two second support plates 16, with the same bidirectional lead screw 17 rotatably connected to the inner walls of the two second support plates 16. The same slide rod 18 is fixed to the inner walls of the two second support plates 16. Two second lead screw nuts 20 are symmetrically sleeved on the side walls of the bidirectional lead screw 17, both of which are adapted to the bidirectional lead screw 17 and slidably connected to the slide rod 18. The two second lead screw nuts 20 are respectively fixed to two L-shaped plates 21. A third motor 19 is fixed to the outer wall of one of the second support plates 16, and the output shaft of the third motor 19 is fixed to the bidirectional lead screw 17. The second moving mechanism includes two third support plates 23, both of which are fixed to the inner walls of the two support plates 16. The same L-shaped plate 21 is fixed at the top of one of the L-shaped plates 21. The side walls of the two third support plates 23 are connected to the same L-shaped plate 21, and the output end of the hydraulic push rod 24 and the stop block 25 are fixed. The third motor 19 drives the bidirectional lead screw 17 to rotate. With the help of the slide rod 18, the two second lead screw nuts 20 move closer or further away from each other, thereby driving the two L-shaped plates 21 to move closer or further away from each other. By adjusting the distance between the two L-shaped plates 21, track plates of different specifications can be clamped and fixed without changing equipment, reducing construction costs, saving time and improving work efficiency. The two hydraulic push rods 24 drive the two stop blocks 25 to move closer to each other until both are located at the bottom of the track plate, thus completing the fixing of the track plate.

[0023] Furthermore, the rotating mechanism includes a worm gear 15, which is sleeved on the side wall of the other end of the rotating shaft 14. Two first support plates 11 are symmetrically fixed on the top of the connecting plate 6. The inner side walls of the two first support plates 11 are rotatably connected to the same worm 12, and the worm 12 meshes with the worm gear 15. A second motor 13 is fixed on the outer side wall of one of the first support plates 11, and the output shaft of the second motor 13 is fixed to the worm 12. The second motor 13 drives the worm 12 to rotate, which in turn drives the rotating shaft 14 to rotate, thereby driving the disc 7 to rotate. This allows for angle adjustment of the track plate. After adjustment, the two hydraulic push rods 24 are driven to move the two stops 25 in the opposite direction, causing the two stops 25 to disengage from the track plate. At this time, the track plate falls precisely into the installation position.

[0024] Working Principle: During use, the rectangular frame 1 is first moved above the track plate. The distance between the two L-shaped plates 21 is adjusted according to the size of the track plate. During adjustment, the power switch of the third motor 19 is turned on, driving the third motor 19 to rotate the bidirectional lead screw 17. This, in conjunction with the slide rod 18, causes the two second lead screw nuts 20 to move closer or further apart, thereby moving the two L-shaped plates 21 closer or further apart. By adjusting the distance between the two L-shaped plates 21, track plates of different specifications can be clamped and fixed without changing equipment, reducing construction costs, saving time, and improving work efficiency. After adjustment, the power switches of the two first motors 5 are simultaneously turned on, driving the two first motors 5 to rotate the two lead screws 9 simultaneously. This, in conjunction with the two first lead screw nuts 10, moves the connecting plate 6 downwards. The downward movement of the connecting plate 6 moves the disc 7 downwards, thereby moving the two L-shaped plates 21 downwards until... The bottom of the track slab and the tops of the two stops 25 are flush. At this time, both ends of the track slab are in close contact with the inner walls of the two L-shaped plates 21. Then, the two hydraulic push rods 24 are driven to move the two stops 25 closer to each other until both are at the bottom of the track slab, thus fixing the track slab. Then, the rectangular frame 1 is moved to transport the track slab to the construction position. The connecting plate 6 is moved downward so that the bottom of the two L-shaped plates 21 is in contact with the ground beforehand. This can limit the ends of the track slab and prevent positional deviation. The power switch of the second motor 13 is turned on, and the second motor 13 drives the worm gear 12 to rotate. In conjunction with the worm wheel 15, the rotating shaft 14 is rotated, which in turn drives the disc 7 to rotate. The angle of the track slab can be adjusted. After the adjustment is completed, the two hydraulic push rods 24 are driven to move the two stops 25 in the opposite direction, so that the two stops 25 are disengaged from the track slab. At this time, the track slab is accurately placed in the installation position.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
