Description

Technical Field

[0001] This utility model relates to the field of railway deceleration jacking technology, and in particular to a railway deceleration jacking puller. Background Technology

[0002] Railway speed reducers are the core equipment for controlling the shunting speed of vehicles in railway marshalling yards. They need to be inspected or replaced regularly, and the removal of the speed reducers is a key part of the maintenance process.

[0003] However, in the existing technology, existing deceleration tops have various specifications due to vehicle models and line requirements (such as differences in external dimensions and installation angles). However, the fixed clamping structure of traditional deceleration top pullers cannot flexibly adjust the spacing and angle to match different deceleration tops, resulting in a narrow range of application for a single tool and increased operation and maintenance costs. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a railway deceleration jack puller, which solves the problem that the existing deceleration jacks have various specifications (such as differences in shape and installation angle) due to the needs of different train models and lines. However, the fixed clamping structure of the traditional puller cannot flexibly adjust the spacing and angle to match different deceleration jacks, resulting in a narrow range of application for a single tool and increased operation and maintenance costs.

[0005] The technical solution of this utility model is as follows: A railway deceleration jacking device includes two connecting frames. Adjustment holes are equidistantly provided on the outer sides of each connecting frame. A rotating shaft is slidably connected inside each adjustment hole. Two connecting rods are rotatably connected between corresponding rotating shafts. A first handle is provided in a groove close to the two connecting frames. A first connecting rod is rotatably connected to the top of the first handle. The end of the first connecting rod away from the first handle is rotatably connected to the corresponding connecting frame. A second connecting rod is rotatably connected to the inner wall of the first connecting rod at one end of the connecting frame. A second handle is rotatably connected between the ends of the two second connecting rods away from the first connecting rod. A clamping block is fixedly connected to the side of the connecting frames close to each other and below the connecting rods.

[0006] Through the above technical solutions, the design of the adjustment hole, rotating shaft and connecting rod makes the puller adaptable to different specifications of deceleration pullers, enhancing the versatility of the device; the lever linkage structure composed of the connecting rod, the first handle and the second handle effectively reduces the force required for pull-out operation and improves operating efficiency; the multi-part hinged cooperation method ensures the stability of the clamping and pull-out process and extends the service life of the device.

[0007] In a preferred embodiment, two connecting blocks are fixedly connected between the two connecting rods, and springs are fixedly connected between the bottom of the first handle and the connecting blocks.

[0008] Through the above technical solution, the spring can be reset by the first handle after use; the connecting block enhances the integrity of the connecting rod structure and improves the device's resistance to deformation by connecting the two connecting rods.

[0009] In a preferred embodiment, rubber pads are fixedly connected to the adjacent sides of the two clamping blocks.

[0010] Through the above technical solution, the use of rubber pads avoids direct contact between metal parts and deceleration tops, effectively preventing scratches and deformation on the surface of deceleration tops and protecting the workpiece; at the same time, the increased friction makes clamping more stable and reliable, preventing the workpiece from slipping during the pulling process and enhancing operational safety.

[0011] In a preferred embodiment, nuts are threaded onto both ends of the rotating shaft and on the outer side of the connecting frame.

[0012] Through the above technical solution, the locking effect of the nut on the rotating shaft prevents the device structure from loosening during operation and ensures the accuracy of the lifting operation; at the same time, the pre-adjustment of the rotating shaft position is adapted to different working conditions, and after debugging, it is locked by the nut, which has the advantage of convenient installation.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the coordinated design of the adjusting hole, rotating shaft, and connecting rod allows the puller to adapt to different specifications of deceleration jacks, enhancing the device's versatility. The lever linkage structure formed by the connecting rod, the first handle, and the second handle effectively reduces the force required for pull-out operations, improving operational efficiency. The multi-part hinged connection ensures stability during clamping and pull-out processes, extending the device's service life. The spring allows the first handle to reset after use. The connecting block's connection to the two connecting rods enhances the overall integrity of the connecting rod structure, improving the device's resistance to deformation. The use of rubber pads avoids direct contact between metal parts and the deceleration jack, effectively preventing scratches and deformation on the deceleration jack surface and protecting the workpiece. Simultaneously, the increased friction makes clamping more stable and reliable, preventing the workpiece from slipping during pull-out and enhancing operational safety. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a technical solution: it includes two connecting frames 1, each with an adjustment hole 4 equidistantly opened on its outer side. A rotating shaft 5 is slidably connected inside each adjustment hole 4. Two connecting rods 6 are rotatably connected between the two rotating shafts 5. A first handle 9 is provided in the groove of the two connecting frames 1 that are close to each other. A first connecting rod 10 is rotatably connected to the top of the first handle 9. The end of the first connecting rod 10 away from the first handle 9 is rotatably connected to the corresponding connecting frame 1. A second connecting rod 11 is rotatably connected to the inner wall of the first connecting rod 10 and located at one end of the connecting frame 1. A second handle 12 is rotatably connected between the ends of the two second connecting rods 11 that are away from the first connecting rod 10. A clamping block 2 is fixedly connected to the side of the connecting frame 1 that is close to each other and located below the connecting rod 6.

[0022] In this embodiment, when force is applied to the second handle 12, the first connecting rod 10 is driven to rotate through the second connecting rod 11, causing the first handle 9 to reciprocate within the groove of the connecting frame 1. At the same time, the rotating shaft 5 slides within the adjusting hole 4 and cooperates with the rotation of the connecting rod 6 to adjust the distance and tilt angle between the two connecting frames 1, ensuring that the clamping block 2 is aligned with the railway deceleration top. The tilt angle of the connecting frame 1 must meet the structural dimensions such as the groove depth and the length of the first connecting rod, so that when the first connecting rod 10 rotates to its limit position, the first handle 9 is still not dislodged from the maximum tilt angle of the groove, thus ensuring that the first handle 9 is always contained within the groove.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, two connecting blocks 7 are fixedly connected between the two connecting rods 6, and springs 8 are fixedly connected between the bottom of the first handle 9 and the connecting blocks 7.

[0024] In this embodiment, when the first handle 9 moves up and down, the connecting block 7 moves with the connecting rod 6, causing the spring 8 to be compressed or stretched between the connecting block 7 and the first handle 9, thereby providing elastic restoring force, assisting the component to reset and buffering the impact during operation.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, rubber pads 3 are fixedly connected to the sides of the two clamping blocks 2 that are close to each other.

[0026] In this embodiment, when the clamping block 2 clamps the railway deceleration top, the rubber pad 3 increases the contact area with the deceleration top through its own elastic deformation, while providing friction and buffering the clamping force, so as to prevent the surface of the deceleration top from being directly squeezed by the metal parts.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, nuts are threaded onto both ends of the rotating shaft 5, which are located on the outside of the connecting frame 1.

[0028] In this embodiment, after the rotating shaft 5 is installed in the adjustment hole 4, the position of the rotating shaft 5 is locked by tightening the nuts at both ends to prevent it from sliding during operation, thereby ensuring that the angle and spacing of the connecting frame 1 remain stable.

[0029] Working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, when force is applied to the second handle 12, the first connecting rod 10 is driven to rotate through the second connecting rod 11, causing the first handle 9 to reciprocate within the groove of the connecting frame 1. Simultaneously, the rotating shaft 5 slides within the adjusting hole 4 and cooperates with the rotation of the connecting rod 6 to adjust the distance and tilt angle of the two connecting frames 1, ensuring that the clamping block 2 is aligned with the railway deceleration top. The tilt angle of the connecting frame 1 must meet the structural dimensions such as the groove depth and the length of the first connecting rod, so that when the first connecting rod 10 rotates to its limit position, the first handle 9 is still not dislodged from the groove at the maximum tilt angle, ensuring that the first handle 9 is always contained within the groove. When the first handle 9 moves up and down, the connecting block 7 moves with the connecting rod 6, causing the spring 8 to be compressed or stretched between the connecting block 7 and the first handle 9, thereby providing elastic restoring force, assisting the component in resetting and buffering the impact during operation. When the clamping block 2 clamps the railway deceleration top, the rubber pad 3 increases the contact area with the deceleration top through its own elastic deformation, while providing friction and buffering the clamping force, preventing the surface of the deceleration top from being directly squeezed by the metal component.
