Description

Technical Field

[0001] This utility model relates to the field of rail fastening technology, specifically a rail bolt fastening device applicable to various situations. Background Technology

[0002] The core purpose of rail bolt tightening is to ensure the reliability of the connections between various rail components, maintain the stability, safety, and durability of the rail structure, and thus ensure the safe, smooth, and efficient operation of trains. The rail is tightly connected to components such as rail clamps (used for joint connections) and fasteners (used for fixing rails and sleepers) through bolts, forming a complete track stress system.

[0003] An internal combustion engine driven fastener is a portable fastening tool powered by an internal combustion engine. It is mainly used in scenarios requiring high strength and high torque for bolt fastening or disassembly.

[0004] However, when using internal combustion engine drive fasteners, due to the large space occupied by some of their structures, when tightening or disassembling bolts in narrow environments, the socket wrench may not be able to reach the bolt surface, and other tools must be used for assistance.

[0005] While internal combustion engine-driven fasteners do have the advantages of high strength and high torque, their connection stability cannot be guaranteed when dealing with rusted or heavily worn bolts (generally during disassembly). Furthermore, when operating at high torque and unable to fully engage, the bolts can cause severe wear on the inside of the socket wrench during rapid rotation, resulting in unnecessary losses.

[0006] Based on this, the present invention provides a rail bolt fastening device applicable to various situations to solve the above problems. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides a rail bolt fastening device applicable to various situations. This utility model has an ingenious structure and focuses on practicality, effectively solving the technical problems of inconvenience in operation in narrow environments and the ability to process rusted or heavily worn bolts.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A rail bolt fastening device applicable to various situations includes an internal combustion engine and a coupling mounted on the internal combustion engine. A mounting bracket is fixedly mounted at the bottom of the coupling, and a drive rod is disposed inside the mounting bracket. A limit sleeve is rotatably connected to the drive rod, and a first spring is fixedly mounted between the limit sleeve and the mounting bracket. A movable tooth is fixedly mounted on the surface of the drive rod, and a fixed tooth that meshes with the movable tooth is fixedly mounted inside the mounting bracket.

An adjusting bracket is fixedly mounted at the bottom of the support sleeve, and a sleeve wrench is provided at the end of the adjusting bracket.

[0010] Preferably, the mounting bracket has a limiting groove inside, and a limiting slider fixedly installed on one side of the limiting sleeve is slidably connected inside the limiting groove.

[0011] Preferably, the connecting frame has a first limiting rod that is fixedly connected to the inside of the mounting frame.

[0012] Preferably, a second drive screw is rotatably connected to the inner side of the adjusting frame, a second screw support is threaded onto the surface of the second drive screw, a push frame is fixedly installed on one side of the second screw support, and a slanted push block is overlapped on the inner side of the push frame. There are two slanted push blocks, which are axially symmetrically arranged. A limit frame is welded to one side of the slanted push block, and a clamping plate that slides inside a socket wrench is fixedly installed on one side of the limit frame. The surface of the clamping plate is provided with clamping pins, and a connecting sleeve is welded to the clamping plate. A second spring is fixedly installed between the connecting sleeve and the adjusting frame.

[0013] Preferably, a fixed screw is welded to one end of the second drive screw, a second knob is welded to one end of the fixed screw, and a fastening nut is threaded onto the surface of the fixed screw.

[0014] Preferably, the inner side of the second lead screw frame is slidably connected to a second limiting rod that is fixedly connected to the inner side of the adjusting frame.

[0015] Preferably, the adjustment frame has a support groove inside, and the clamping plate is slidably connected inside the support groove.

[0016] Preferably, a connecting rod is fixedly installed on the inner side of the adjustment frame, and a connecting sleeve is slidably connected to the connecting rod.

[0017] Preferably, a first handrail is fixedly installed on the surface of the internal combustion engine, and a controller is provided on the first handrail; a second handrail is fixedly installed on the surface of the coupling.

[0018] This utility model has the following technical advantages.

[0019] 1. This utility model allows the moving teeth to disengage from the fixed teeth by pushing the first knob inward. Then, by rotating the first knob, the drive rod and the first drive screw rotate, thereby moving the first screw frame, connecting frame, adjusting frame, and socket wrench.

When facing rusty or worn bolts, it can fit more stably, ensuring the stability and efficiency of subsequent bolt processing. By setting a fastening nut, the second drive lead screw can be locked and protected, ensuring the stability of the work after adjustment. Attached Figure Description

[0031] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0032] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] This utility model relates to a rail bolt fastening device applicable to various situations, comprising an internal combustion engine 2 and a coupling 3 mounted on the internal combustion engine 2. The coupling 3 is an eccentric coupling, and a mounting frame 5 is fixedly mounted on the bottom of the coupling 3. The mounting frame 5 provides reasonable installation space and also helps to protect part of the structure. A drive rod 12 is provided inside the mounting frame 5. The drive rod 12 consists of a smooth shaft and a protrusion that mates with the inside of a limiting sleeve 16, so that the drive rod 12 and the limiting sleeve 16 can only rotate relative to each other and cannot slide relative to each other. A limiting sleeve 16 is rotatably connected to the drive rod 12. A first spring 13 is provided between the limiting sleeve 16 and the mounting bracket 5, and is sleeved on the drive rod 12. The first spring 13 can elastically limit the limiting sleeve 16 and the drive rod 12. A moving tooth 18 is fixedly installed on the surface of the drive rod 12. A fixed tooth 17 that can mesh with the moving tooth 18 is fixedly installed on the inner side of the mounting bracket 5. The fixed tooth 17 is a residual tooth, which can mesh and limit the moving tooth 18. A first knob 11 is welded to one end of the drive rod 12. Placed outside the mounting bracket 5, the first knob 11 can drive the drive rod 12. A first drive screw 19 is fixedly mounted on the other end of the drive rod 12. The other end of the first drive screw 19 is movably positioned so as not to contact the upper wall of the mounting bracket 5, allowing the first drive screw 19 to slide and rotate. A first screw holder 20 is threaded onto the surface of the first drive screw 19. A connecting bracket 8 is fixedly mounted on one side of the first screw holder 20. A guide bracket 9 is fixedly mounted on the output shaft end of the eccentric coupling 3. The surface of the guide bracket 9 is machined with multiple teeth. A support sleeve 36 is rotatably connected to the guide frame 9 and slidably connected inside it. The support sleeve 36 is a metal sleeve and has a groove machined inside it that matches the multi-toothed surface of the guide frame 9. An adjustment frame 10 is fixedly installed at the bottom of the support sleeve 36. A sleeve wrench 6 is provided at the end of the adjustment frame 10. A limit groove 14 is opened inside the mounting frame 5. A limit slider 15 is slidably connected inside the limit groove 14 and fixedly installed on one side of the limit sleeve 16. A first limit rod 7 is slidably connected inside the connecting frame 8 and fixedly connected to the inside of the mounting frame 5.

[0034] In this embodiment, when tightening or removing bolts on the rail, the first handrail 1 and the second handrail 4 can be held directly to control the internal combustion engine 2, which drives the guide frame 9 connected to the output end of the coupling 3 to rotate. This, in turn, drives the support sleeve 36, the adjusting frame 10, and the socket wrench 6 to rotate. The socket wrench 6 can be used to directly tighten or remove the bolts. When the bolt being processed is in a relatively narrow environment, the first knob 11 can be pushed inward to disengage the moving gear 18 from the fixed gear 17. Then, by rotating the first knob 11, the drive rod 12 and... The first drive screw 19 rotates, thereby driving the first screw frame 20, connecting frame 8, support sleeve 36, adjusting frame 10 and socket wrench 6 to move. The extension length of socket wrench 6 is adjusted and controlled according to the actual environment of bolt processing. After adjusting the extension length of socket wrench 6, the first knob 11 is released. At this time, with the help of the elastic force of the first spring 13, the limiting sleeve 16, drive rod 12 and moving gear 18 are driven to reset, so that the moving gear 18 engages and is fixed with the fixed gear 17. Then the bolt can be processed through the above operation steps.

[0035] As an example, a second drive screw 25 is rotatably connected to the inner side of the adjusting frame 10. The second drive screw 25 is composed of a structure with smooth rods at both ends and a threaded groove in the middle. A second screw frame 21 is threadedly connected to the surface of the second drive screw 25. A push frame 23 is fixedly installed on one side of the second screw frame 21. The push frame 23 is a hollow rectangle and can push and limit the inclined groove push block 24. Two inclined groove push blocks 24 are overlapped on the inner side of the push frame 23. The two inclined groove push blocks 24 are arranged symmetrically between each other. A limit frame 27 is welded to one side of the inclined groove push block 24. The limit frame 27 is U-shaped. A clamping plate 31 that slides in the socket wrench 6 is fixedly installed on the lower side of the limit frame 27. The surface of the clamping plate 31 is provided with clamping pins 32. There are several clamping pins 32. The clamping plate 31 and the clamping pins 32 can clamp the bolts and form a strong engagement on the surface of rusted or worn bolts. To improve and ensure disassembly stability, connecting sleeves 29 are welded to both ends of the clamping plate 31. A second spring 30 is fixedly installed between the connecting sleeve 29 and the adjusting frame 10. A fixing screw 35 is welded to one end of the second drive screw 25, and a second knob 26 is welded to the other end of the fixing screw 35. The second knob 26 can easily drive and control the second drive screw 25. A fastening nut 34 is threaded onto the surface of the fixing screw 35. The fastening nut 34 cooperates with the fixing screw 35 to stably lock the second drive screw 25, improving the stability of the second drive screw 25 when no drive is needed. A second limiting rod 22 is slidably connected to the inner side of the second screw frame 21 and fixedly connected to the inner side of the adjusting frame 10. A support groove 33 is opened inside the adjusting frame 10, and the clamping plate 31 is slidably connected inside the support groove 33. A connecting rod 28 is fixedly installed inside the adjusting frame 10, and the connecting sleeve 29 is slidably connected to the connecting rod 28.

[0036] In this embodiment, when disassembling rusted bolts or bolts with severe surface wear, the socket wrench 6 can be placed on the surface of the bolt to be treated. Then, the second knob 26 is turned to drive the second drive screw 25 to rotate, thereby driving the second screw frame 21 and the push frame 23 to move. The push frame 23 gradually pushes the inclined groove push block 24 and the limit frame 27 to move inward. During the inward movement of the limit frame 27, the clamping plate 31 will gradually move inward. The gradually moving clamping plate 31 clamps the bolt surface with the help of the clamping pin 32. After clamping, the fastening nut 34 is rotated so that the fastening nut 34 abuts against one side of the adjusting frame 10 to lock and protect the second drive screw 25. Finally, the guide frame 9, the connecting frame 8, the adjusting frame 10 and the socket wrench 6 are driven to rotate to treat the bolt.

[0037] As an example, a first handrail 1 is fixedly mounted on the surface of the internal combustion engine 2, and a controller is provided on the first handrail 1. A second handrail 4 is fixedly mounted on the surface of the coupling 3.

[0038] Working principle:

[0039] S1. When tightening or loosening bolts, first select a different socket wrench 6 according to the bolt size, and then snap the socket wrench 6 into the adjusting bracket 10. After snapping the socket wrench 6 into place, put the socket wrench 6 onto the bolt surface. Then control the internal combustion engine 2 to drive the guide bracket 9 connected to the output end of the coupling 3 to rotate, thereby driving the connecting bracket 8, adjusting bracket 10 and socket wrench 6 to rotate, and use the rotating socket wrench 6 to process the bolt.

[0040] S2. During the bolt processing, the environment of the rail laying may prevent the device from connecting with the bolt, such as when the bolt is in a deep gap. In this case, the internal combustion engine 2 can be turned off first, and the first knob 11 can be pushed inward to move the moving gear 18 away from the fixed gear 17. Then, by rotating the first knob 11, the drive rod 12 and the first drive screw 19 can be rotated, thereby moving the first screw frame 20, the connecting frame 8, the adjusting frame 10, and the socket wrench 6. The extension length of the socket wrench 6 can be adjusted and controlled according to the actual bolt processing environment. After adjusting the extension length of the socket wrench 6, the pressing action can be released. At this time, the limit sleeve 16 will drive the drive rod 12 and the moving gear 18 to reset. After the moving gear 18 is reset, it can cooperate with the fixed gear 17 to lock. After locking the drive rod 12 and the first drive screw 19, the socket wrench 6 can be put on the bolt, and the bolt can be processed through the steps in S1.

[0041] S3. When disassembling bolts, the socket wrench 6 can be directly placed on the bolt surface and the bolt can be disassembled through the above steps. When dealing with rusty or severely worn bolts, the socket wrench 6 can be placed on the bolt surface first, and then the second knob 26 can be turned to drive the second drive screw 25 to rotate, thereby driving the second screw bracket 21 and the push bracket 23 to move. The push bracket 23 gradually pushes the inclined groove push block 24 and the limit bracket 27 to move inward. During the inward movement of the limit bracket 27, it will drive... The clamping plate 31 gradually moves inward, and the clamping plate 31 moves inward, causing the clamping pin 32 to follow. The clamping pin 32 gradually engages with the surface or interior of the bolt, and after engaging, the fastening nut 34 is rotated so that the fastening nut 34 overlaps with the surface of the adjusting frame 10. At this time, the second drive screw 25 is locked, thereby locking the second screw frame 21, the push frame 23, the inclined groove push block 24 and the limit frame 27. After locking, the bolt can be disassembled through the above operation steps.

[0042] This utility model has the following technical advantages.

[0043] 1. This utility model allows the moving teeth to disengage from the fixed teeth by pushing the first knob inward. Then, by rotating the first knob, the drive rod and the first drive screw rotate, thereby moving the first screw frame, connecting frame, adjusting frame, and socket wrench. The length of the socket wrench can be adjusted according to the actual environment for bolt processing. By controlling the extension length of the socket wrench, the equipment can tighten or loosen bolts installed in narrow environments. By setting the first spring, the position of the moving teeth can be restricted. Together with the fixed teeth, the moving teeth, drive rod, and first screw frame can be locked, ensuring the stability of the socket wrench after adjustment.

[0044] 2. By rotating the second knob, this utility model can drive the second lead screw frame and the push frame to move. The push frame gradually pushes the inclined groove push block and the limit frame to move inward. During the inward movement of the limit frame, it will drive the clamping plate to move inward. The gradually moving clamping plate will engage with the bolt surface with the help of the clamping pin. When facing rusty or worn bolts, it can fit more stably, ensuring the stability and efficiency of subsequent bolt processing. By setting a fastening nut, the second drive lead screw can be locked and protected, ensuring the stability of the work after adjustment.
