Description

Technical Field

[0001] The invention belongs to the field of rail assembly, and in particular relates to a sleeper swinging device for rail production. Background Art

[0002] During the assembly process of the rail track, the gantry crane and the lifting equipment first need to lift the sleepers from the finished sleeper placement area to the fastener placement area, then place the fasteners and pads on the sleepers, and then the gantry crane and the lifting equipment need to send the sleepers to the assembly area for assembly with the rails.

[0003] During the process of lifting the sleepers with the help of gantry crane and lifting equipment, each lifting requires multiple workers to operate the lifting equipment to clamp the sleepers, and then operate the lifting equipment again to separate the sleepers after lifting the sleepers to the work station. This is not only troublesome to operate, but also increases the workload of workers.

[0004] In addition, when the gantry crane lifts the sleepers to the work station, workers are required to guide the sleepers so that they can be placed in the appropriate position. There are certain risks in the gantry crane lifting the sleepers in mid-air and the workers guiding the sleepers to fall.

[0005] In summary, we propose a sleeper swing device for rail production to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and examples.

[0035] See also Figure 1-6 The present invention provides a technical solution for a sleeper device for rail production:

[0036] Example 1:

[0037] according to Figure 1-5 As shown, it includes a support platform 1, a sleeper load-bearing adjustment mechanism, N groups of conveying mechanisms and M groups of lifting components.

[0038] N groups of conveying mechanisms are arranged below the support platform 1. In this embodiment, there are two groups of conveying mechanisms. The conveying mechanisms include a chain conveyor 5 and mounting seats 8 located on both sides of the chain conveyor 5. The cross-section of the mounting seat 8 is L-shaped. The side of the mounting seat 8 facing away from the chain conveyor 5 is fixedly connected with a rib 9 to increase the structural strength of the mounting seat 8.

[0039] The chain conveyor 5 is installed between two mounting seats 8. A plurality of connecting components 10 are installed between the chain plates of the chain conveyor 5 and the support platform 1. The plate conveyor 5 drives the movement of the support platform 1 through the connecting components 10, and then sends the sleepers into the fastener placement area or assembly area.

[0040] A plurality of supporting legs 62 are fixedly mounted on the bottom of the mounting base 8 , and two crossbeams 61 are mounted between two adjacent supporting legs 62 .

[0041] The sleeper load-bearing adjustment mechanism includes a driving assembly, two connecting beams 21, two load-bearing beams 22 and N push plates 29. The connecting beam 21 is fixedly installed between the two load-bearing beams 22. N guide beams 28 are fixedly connected between the two connecting beams 21. The load-bearing beams 22 and the guide beams 28 support the sleepers. A sliding hole is opened in the push plate 29, so that the push plate 29 is mounted on the guide beam 28 and can slide axially along the guide beam 28.

[0042] The driving assembly includes a threaded rod 25 and a driving motor 23. Bearings are respectively installed at both ends of the threaded rod 25. The two bearings are respectively installed in the two connecting beams 21. The driving motor 23 is installed on the outer side of any connecting beam 21. Its output shaft is fixedly connected to the threaded rod 25. A nut 26 is threadedly connected to the threaded rod 25. Connecting plates 27 are respectively fixedly connected on both sides of the nut 26. The connecting plates 27 are fixedly connected to the push plates 29. The driving motor 23 drives the threaded rod 25 to rotate in the forward direction. During the rotation, the threaded rod 25 drives the push plates 29 to move through the nuts 26 and the connecting plates 27. The two push plates 29 push the sleepers to move on the two load-bearing beams 22, and then adjust the position of the sleepers so that the sleepers are placed in the appropriate position, so that workers do not need to manually adjust the position of the sleepers, thereby reducing the workload of workers.

[0043] M groups of lifting components are installed on the support platform 1. In this embodiment, the lifting components are electric push rods 23. Of course, oil cylinders or air cylinders can also be used. The electric push rods 23 are fixedly installed at the bottom of the support platform 1. The telescopic ends thereof pass through the through holes opened in the support platform 1 and are fixedly connected to the bottom of the load-bearing beam 22. The synchronous telescopic movement of the four electric push rods 23 is enough to drive the two load-bearing beams 22 to move up and down, thereby adjusting the height of the load-bearing beams 22.

[0044] A power storage control box 4 is installed at the bottom of the support platform 1. The power storage control box 4 is electrically connected to the electric push rod 2 3. The power storage control box 4 provides the required power for the electric push rod 2 3 and controls the extension and retraction of the electric push rod 2 3.

[0045] It also includes two groups of sleeper swinging frames, which are located on both sides of the chain conveyor 5. The sleeper swinging frames include a bearing platform 74 and multiple hydraulic cylinders 72. A support frame 71 is installed at the bottom of the bearing platform 74. The two ends of the sleeper are respectively placed on the bearing platforms 74 on both sides, and the sleepers are supported by the bearing platforms 74. Multiple hydraulic cylinders 72 are installed on the top of the bearing platforms 74 from front to back. The telescopic ends of the multiple hydraulic cylinders 72 are installed with the same aligning plate 73. Through the synchronous extension of the multiple hydraulic cylinders 72, the aligning plates 73 on both sides are brought close to each other, and the two ends of the multiple sleepers are aligned and centered to facilitate the subsequent assembly of the rail row.

[0046] In specific use, the sleeper swinging device for rail production of the present invention first places the finished sleeper on the two load beams 22 by means of a lifting device or a forklift, then controls the operation of the drive motor 23, which drives the threaded rod 25 to rotate in the forward direction. During the rotation process, the threaded rod 25 drives the push plate 29 to move through the nut 26 and the connecting plate 27. The two push plates 29 push the sleeper to move on the two load beams 22, and then adjust the position of the sleeper to place the sleeper in a suitable position.

[0047] Then, the driving motor 23 is controlled again to rotate the threaded rod 25 in the reverse direction, and the push plate 29 is reset. Then, the above steps are repeated to place the subsequent sleepers on the two load beams 22.

[0048] After the multiple sleepers are placed, the two sets of chain conveyors 5 are controlled to work synchronously. The chain conveyors 5 drive the support platform 1, the two load beams 22 and the multiple sleepers through the connecting components 10 to move the sleepers into the fastener placement area or assembly area.

[0049] After the sleepers are transported to the appropriate location, the four sets of electric push rods 23 are controlled by the battery control box 4 to synchronously retract, so that the two load beams 22 are lowered and the multiple sleepers are placed on the load platforms 74 on both sides;

[0050] Finally, after multiple sleepers are placed in order on the supporting platforms 74 on both sides, the multiple hydraulic cylinders 72 are controlled to extend synchronously so that the aligning plates 73 on both sides are close to each other, and the two ends of the multiple sleepers are aligned and centered to facilitate the subsequent assembly of the rail row.

[0051] Example 2:

[0052] Based on the first embodiment, Figure 1 and Figure 3 As shown, it also includes N groups of pulleys 11 installed at the bottom of the support platform 1. The pulleys 11 are in contact with the top of the mounting seat 8. The support platform 1 is supported by the pulleys 11 to reduce the weight borne by the chain conveyor 5 and protect the chain conveyor 5. At the same time, under the action of the pulleys 11, the safety and stability of the sleepers during transportation can be guaranteed.

[0053] Example 3:

[0054] Based on the first embodiment, Figure 1 、 Figure 5 and Figure 6 As shown, it also includes multiple electric push rods 24 and a common seat 211 arranged in the load-bearing beam 22. The multiple electric push rods 24 are respectively fixedly installed at the bottom of the load-bearing beam 22, and their telescopic ends pass through the bottom wall of the load-bearing beam 22 and are fixedly connected to the common seat 211. The extension and retraction of the electric push rods 24 adjusts the height of the common seat 211. The electric push rods 24 are electrically connected to the power storage control box 4.

[0055] A plurality of support wheels 210 are installed on the top of the common seat 211 in sequence from front to back. The support wheel 210 is arranged in a rectangular hole on the top of the load-bearing beam 22. After the position of the sleeper is adjusted, the support wheel 210 can be stored in the rectangular hole, and the sleeper can be slowly lowered onto the load-bearing beam 22 and the guide beam 28 to ensure the stability of the sleeper during transportation. When the upper end of the support wheel 210 protrudes from the rectangular hole, it contacts the bottom of the sleeper, and the driving assembly drives the two push plates 29 to move. The push plates 29 push the sleeper on the support wheel 210 to move during the movement, and then under the action of the support wheel 210, the friction between the sleeper and the load-bearing beam 22 is reduced, making the sleeper easy to move.
