Description

Technical Field

[0001] This application relates to the technical field of railway sleepers, and in particular to a railway sleeper suspension device. Background Technology

[0002] When replacing damaged railway sleepers located at the bottom of the rails, the stone debris at the bottom of the sleeper needs to be dug out to facilitate the removal of the damaged sleeper due to the anchor bolts on the sleeper. When inserting the new sleeper, there will be a gap between it and the bottom of the existing rail. The sleeper needs to be lifted to make it fit tightly against the rail. Then, the connecting parts between the sleeper and the rail are installed, the nuts are put on, and the screws are tightened.

[0003] Currently, after new sleepers are installed, they are usually pried up with crowbars to raise both ends and make them fit snugly against the bottom of the rail. However, when the gap between the new sleeper and the bottom of the rail is large, it is necessary to raise it multiple times. Moreover, the use of crowbars is affected by the limited space on both sides of the railway, which is not conducive to the safety and efficiency of construction operations. Therefore, there is still room for improvement. Utility Model Content

[0004] To reduce the construction difficulty of repeatedly raising the sleepers when installing new sleepers to the bottom of the rails due to the large gap, and to avoid the problem of site restrictions, thereby improving the safety and construction efficiency of sleeper replacement, this application provides a railway sleeper suspension device.

[0005] The railway sleeper suspension device provided in this application adopts the following technical solution: A railway sleeper suspension device includes a support member positioned on a rail, a clamp connected to the sleeper, and a long rod; vertical bolts are pre-fixed on the sleeper on corresponding sides of the rail, the clamp is clamped and fixed on one of the vertical bolts, the long rod is positioned on the support member, one end of the long rod is connected to the clamp, and the other end extends along the length of the sleeper; rail fasteners for positioning the rail are installed on the vertical bolts.

[0006] By adopting the above technical solution, when replacing sleepers, the vertical bolts fixed to the new sleepers are clamped with lifting clamps. Then, using the lever principle and the support members on the existing rails as fulcrums, the end of the long rod away from the vertical bolts is pressed down, which can achieve the purpose of lifting the sleeper so that it is close to the bottom of the rail. Finally, the rail fasteners are fixed to complete the installation. This reduces the construction difficulty of repeatedly raising the sleepers when installing new sleepers to the bottom of the rails due to the large gap, and avoids the problem of site restrictions. The operation is simple, saves labor costs, and improves the safety and construction efficiency of sleeper replacement.

[0007] Preferably, the support includes a rail head clamp, a support frame, a support sleeve, and a crossbar. The rail head clamp is held in place by the rail head. The support frame is positioned opposite to and fixed to the upper part of the rail head clamp. The support sleeve is fixed to the corresponding support frame. The crossbar passes through and is rotatably connected to the corresponding support sleeve. The long rod is positioned on the crossbar.

[0008] By adopting the above technical solution, the rail head clamp is clamped and positioned on the rail, and the crossbar is supported by the support frame and support sleeve. The long rod is positioned on the crossbar, providing a positioning fulcrum for the long rod, so that the long rod can rotate using the existing rail as a fulcrum. When the end of the long rod away from the clamp is pressed down, the other end of the long rod can drive the clamp to lift, thereby raising the sleeper to be close to the bottom of the rail.

[0009] Preferably, the long rod is provided with a plurality of slots spaced apart along its length, and the crossbar is positioned at the slots.

[0010] By adopting the above technical solution, the relative positions of the long rod and the crossbar are adjusted by using the spaced slots opened on the long rod, so as to adjust the correct position between the bottom of the sleeper and the rail, that is, to ensure that the bottom of the rail is between the two opposing bolts on the sleeper.

[0011] Preferably, the lifting clamp is connected to the long rod via a connecting structure.

[0012] Preferably, the connection structure includes a movable sleeve, a connecting plate, and a pin. The movable sleeve is threaded onto a long rod, the connecting plate is fixed to the lifting clamp, and the bottom of the movable sleeve has a receiving groove for the connecting plate to be inserted. The pin is inserted and fixed at the corresponding positions of the movable sleeve and the connecting plate.

[0013] By adopting the above technical solution, the connecting plate and the pin are used to connect the lifting clamp and the movable sleeve rod. The movable sleeve rod is threaded to the long rod to connect the lifting clamp and the long rod, so as to use the lever principle to drive the lifting clamp and the vertical bolt to lift the sleeper tightly against the bottom of the rail.

[0014] Preferably, the lifting clamp is configured as a scissor type structure, with a scissor arm rotatably connected to the lifting clamp.

[0015] By adopting the above technical solution, when the scissor-type clamp holds an object, the clamping force automatically increases as the scissor arm retracts, achieving a self-locking effect of "the tighter it is, the more it is lifted". Moreover, after the scissor structure is closed in place, it can naturally form a geometric self-locking state, thereby effectively preventing the vertical bolt from slipping during the lifting process, maintaining stable clamping of the vertical bolt, and improving operational safety.

[0016] In summary, this application includes at least one of the following beneficial technical effects: When replacing railway sleepers, the vertical bolts fixed to the new sleeper are clamped with lifting clamps. Then, using the lever principle and the support members on the existing rail as fulcrums, the end of the long rod away from the vertical bolt is pressed down, which lifts the sleeper so that it is close to the bottom of the rail. Finally, the rail fasteners are fixed to complete the installation. This reduces the construction difficulty of repeatedly raising the sleeper when installing a new sleeper to the bottom of the rail due to the large gap, and avoids the problem of site restrictions. The operation is simple, saves labor costs, and improves the safety and construction efficiency of replacing sleepers. The rail head clamp is positioned on the rail. The crossbar is supported by the support frame and support sleeve. The long rod is positioned on the crossbar, providing a positioning fulcrum for the long rod. The long rod can rotate using the existing rail as a fulcrum. When the end of the long rod away from the clamp is pressed down, the other end of the long rod can drive the clamp to lift, thereby lifting the sleeper to be close to the bottom of the rail. The relative positions of the long rod and the crossbar are adjusted by using the spaced slots on the long rod to adjust the correct position between the sleeper and the bottom of the rail, that is, to ensure that the bottom of the rail is between the two opposing bolts on the sleeper. When a scissor-type lifting clamp holds an object, the clamping force automatically increases as the scissor arm retracts, achieving a self-locking effect of "the tighter the clamping, the tighter it becomes." Furthermore, the scissor structure can naturally form a geometric self-locking state after closing in place, thereby effectively preventing the vertical bolt from slipping during the lifting process, maintaining stable clamping of the vertical bolt, and improving operational safety.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This application discloses a railway sleeper suspension device, referring to... Figure 1The system includes a support member 2 positioned on the rail 1, a clamp 4 connected to the sleeper 3, and a long rod 5. The long rod 5 is positioned on the support member 2, with one end connected to the clamp 4 and the other end extending along the length of the sleeper 3. When replacing the sleeper 3, the position of the long rod 5 on the support member 2 is used as the fulcrum, that is, the existing rail 1 is used as the support point. The end of the long rod 5 away from the clamp 4 is pressed down, and the clamp 4 drives the new sleeper 3 to be lifted, so that the sleeper 3 is close to the bottom of the rail 1.

[0021] Reference Figure 1 , 2 The sleeper 3 has pre-fixed vertical bolts 31 on both sides of the rail 1. The lifting clamp 4 is a scissor-type structure with a scissor arm 41 rotatably connected to it. The lifting clamp 4 clamps and fixes the nut of the vertical bolt 31 on the outer side of the sleeper 3 near the rail 1. When the lifting clamp 4 clamps an object, the clamping force automatically increases as the scissor arm 41 retracts, achieving a self-locking effect of "the more it is lifted, the tighter it becomes". Moreover, after the scissor structure is closed in place, it can naturally form a geometric self-locking state, thereby effectively preventing the vertical bolt 31 from slipping during the lifting process, maintaining stable clamping of the vertical bolt 31, and improving the safety of operation.

[0022] Reference Figure 1 , 2 The lifting clamp 4 is connected to the long rod 5 via a connecting structure 6. The connecting structure 6 includes a movable sleeve 61, a connecting plate 62, and a pin 63. The movable sleeve 61 is threaded onto the long rod 5, and the connecting plate 62 is fixed to the upper part of the lifting clamp 4. The bottom of the movable sleeve 61 has a receiving groove 611 for the connecting plate 62 to be inserted. The pin 63 is inserted and fixed at the corresponding positions of the movable sleeve 61 and the connecting plate 62. The connecting plate 62 and the pin 63 connect the lifting clamp 4 to the movable sleeve 61. The movable sleeve 61 is then connected to the long rod 5 so that the lifting clamp 4 and the vertical bolt 31 can be lifted by using the lever principle through the long rod 5, so as to make the sleeper 3 fit tightly against the bottom of the rail 1.

[0023] Reference Figure 1 , 3 The support component 2 includes a rail head clamp 21, a support frame 22, a support sleeve 23, and a crossbar 24. The rail head clamp 21 is clamped to the rail head of the rail 1. The support frame 22 is arranged opposite to and fixed to the upper part of the rail head clamp 21 in a direction perpendicular to the extension of the long rod 5. The support sleeve 23 is fixed above the corresponding support frame 22. The crossbar 24 passes through the corresponding support sleeve 23, and the two end side walls of the crossbar 24 are respectively fixed with rotating rings that are rotatably connected to the corresponding support sleeve 23. The long rod 5 is positioned on the crossbar 24. The rail head clamp 21 is clamped and positioned on the rail 1. The support frame 22 and the support sleeve 23 support the crossbar 24. The long rod 5 is positioned on the crossbar 24, providing a positioning fulcrum for the long rod 5, so that the long rod 5 can rotate using the existing rail 1 as a fulcrum. The sleeper 3 is lifted to be close to the bottom of the rail 1 using the lever principle.

[0024] Reference Figure 1 , 3 The bottom of the long rod 5 is provided with several slots 51 spaced apart along the length direction. The crossbar 24 is positioned at the slots 51. The relative position of the long rod 5 and the crossbar 24 can be adjusted to adjust the correct position between the bottom of the sleeper 3 and the rail 1, that is, to ensure that the bottom of the rail 1 is between the two opposing bolts 31 on the sleeper 3.

[0025] Reference Figure 1 The rail fastener 7 for positioning rail 1 is installed on the vertical bolt 31. When the end of the long rod 5 away from the vertical bolt 31 is pressed down, the other end of the long rod 5 drives the lifting clamp 4 and the vertical bolt 31 to lift up until the bottom of the rail 1 is tightly against the sleeper 3. Then, the new sleeper 3 is positioned on the rail 1 by installing the rail fastener 7 on both sides of the rail 1. The two opposite rails 1 are fixed in the same way, thus fixing the railway track frame.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
