Description

Technical Field

[0001] This utility model relates to a hydraulic cylinder rail clamping component, specifically to a synchronous hydraulic cylinder rail clamping device. Background Technology

[0002] Synchronous hydraulic cylinder rail clamping device is a mechanical device used to clamp rails. It is widely used in the construction field, especially in the jacking and sliding construction of large space frame and truss structures. The device is controlled by a hydraulic system and uses two rail clamping units and synchronous hydraulic cylinders set on both sides of the rail to achieve stable clamping and loosening of the rail, thereby ensuring the safety and reliability of the equipment running on the rail.

[0003] In the prior art, 202020709716.X discloses a rail clamp. This utility model discloses a rail clamp, belonging to rail connection equipment. The rail clamp includes a horizontal arm, a rail clamping arm, a telescopic shaft, rollers, and an opening and closing cylinder. One end of the horizontal arm is detachably fixed to the engineering equipment by a mounting component, and the other end of the horizontal arm is suspended. There are two rail clamping arms, which are swayably mounted on the horizontal arm by a mounting shaft. A rotating shaft seat is provided at the outer end of the rail clamping arm. The telescopic shaft is mounted on the rotating shaft seat by a thread and its position is adjustable. The rollers are rotatably disposed at the end of the telescopic shaft. The opening and closing cylinder is installed between the two rail clamping arms to drive the opening and closing of the rail clamping arms. By controlling the extension and retraction of the opening and closing cylinder, the rail clamp can be automatically opened and closed, and the rollers are slidably connected to the rail.

[0004] The rail clamps proposed in the prior art adopt a new driving method and layout scheme, which reduces the overall size and is suitable for automated control. They have the advantages of strong clamping and reliable operation. However, they cannot rely on the hydraulic system to control and clamp the rail, resulting in insufficient clamping stability and inability to perform stable clamping. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a synchronous hydraulic cylinder rail clamping device.

[0006] This utility model is achieved using the following technical solution: a synchronous hydraulic cylinder rail clamping device, comprising a rail clamping component, which is a rail clamping box. The rail clamping component is a rail clamping module, and an assembly plate is provided on the rail clamping module. Connecting bolts are provided on the assembly plate, and a traction rod is fixed to the assembly plate by the connecting bolts. A synchronous hydraulic cylinder for controlling the extension and retraction of the traction rod is provided on the traction rod. A limiting component, a limiting baffle, is provided in the rail clamping box. The rail clamping module uses rail clamping wedges, and wear-resistant gaskets are provided on the rail clamping wedges.

[0007] The limiting baffles are distributed inside the rail clamping box, and the limiting baffles are provided with movable areas. The traction rod is provided with sub-baffles, and the sub-baffles move within the movable areas of the limiting baffles.

[0008] The rail clamp box is provided with a positioning component, which is a positioning plate. The positioning plate has an assembly hole, and an assembly bolt is installed in the assembly hole.

[0011] Compared to existing technologies, this invention allows the track to be placed along the clamping space inside the clamping box when track clamping is required. Then, relying on the cooperation between the synchronous hydraulic cylinder and the clamping wedge on the clamping box, the track is effectively clamped by the clamping wedge, further ensuring the clamping effect and meeting the requirements for track clamping stability. A limit baffle is set inside the clamping box, which can control the extension and retraction length of the synchronous hydraulic cylinder during clamping, preventing the outer surface of the track from being subjected to excessive squeezing force, and allowing for good control of the clamping distance and force.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] A synchronous hydraulic cylinder rail clamping device includes a rail clamping component, which is a rail clamping box 1. The rail clamping component is housed within the rail clamping box 1 and is a rail clamping module. An assembly plate 3 is mounted on the rail clamping module, and connecting bolts 2 are mounted on the assembly plate 3. A traction rod 4 is fixed to the assembly plate 3 by the connecting bolts. A synchronous hydraulic cylinder 5 for controlling the extension and retraction of the traction rod 4 is mounted on the traction rod 4. A limiting component, a limiting baffle 6, is provided within the rail clamping box 1. The rail clamping module uses rail clamping wedges 7, and wear-resistant gaskets 8 are mounted on the rail clamping wedges 7.

[0018] To ensure more stable rail clamping, a rail clamping box 1 is used. The clamping box 1 provides excellent rail clamping. A clamping space is provided within the clamping box 1, through which the rail passes. The synchronous hydraulic cylinder 5 and the rail clamping wedge 7 on the clamping box 1 work together. Under the action of the synchronous hydraulic cylinder 5, the rail clamping wedge 7 is pushed to clamp the rail, making rail clamping more convenient and stable. Simultaneously, to restrict the movement of the traction rod 4 on the synchronous hydraulic cylinder 5 and prevent excessive traction length, the force applied to the rail clamping wedge 7 is more... The high height of the track can cause damage due to external forces. Therefore, a limit baffle 6 is installed inside the rail clamping box 1. The limit baffle 6 is distributed inside the rail clamping box 1 and has an movable area. A sub-baffle 9 is installed on the traction rod 4. The sub-baffle 9 moves within the movable area on the limit baffle 6. This prevents the traction rod 4 from applying excessive force and avoids excessive stress on the outer surface of the track. A positioning component, namely a positioning plate 10, is installed outside the rail clamping box 1. The positioning plate 10 has an assembly hole and an assembly bolt is installed in the assembly hole.

[0019] A cover plate 11 is provided on the rail clamping box 1. The cover plate 11 and the rail clamping box 1 are fixed together by bolts. A breathable mesh plate 12 is provided on the cover plate 11. The breathable mesh plate can effectively dissipate heat, which further enhances the air permeability of the rail clamping box. An assembly part is provided between the rail clamping wedge 7 and the traction rod 4. The assembly part is an assembly gasket 13. The assembly gasket 13 is a flexible sealing gasket. The sealing gasket 13 can better seal the rail clamping wedge 7 and the traction rod 4, which is more conducive to the sealing of the assembly between the rail clamping wedge 7 and the traction rod 4, and meets the working requirement of the rail clamping wedge 7 being firmly fixed.

[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
