Description

Technical Field

[0001] This utility model relates to the field of track fastener disassembly technology, specifically a quick disassembly device for railway track fasteners. Background Technology

[0002] During railway line construction, the dismantling of track fasteners usually requires the cooperation of a large number of personnel. Railway fasteners are mainly fixed by a structure that connects nuts and pre-embedded screws, so the main task during dismantling is to remove the nuts.

[0003] In the prior art, Chinese utility model patent CN221871860U discloses a "tool for disassembling track fastener nuts," comprising: a sleeve and a tube. The lower end of the sleeve has a connecting hole, and the upper end of the sleeve is coaxially provided with a connecting head. There is a gap between the connecting head and the sleeve, and the gap size is greater than the thickness of the nut. The connecting head and the sleeve are connected by a pair of connecting parts. A locking pin is provided through the side wall of the middle section of the sleeve, and the locking pin is movable perpendicular to the axis of the sleeve.

[0004] Although some quick-release devices for track fasteners already exist on the market, which can effectively collect the nuts while removing them, in actual use, operators still need to manually remove the nuts from inside the sleeve after each removal. This process not only increases the complexity of the operation but also significantly reduces work efficiency. Therefore, we propose a quick-release device for railway track fasteners. Utility Model Content

[0005] One of the technical problems to be solved in this application is: how to design a quick-release device for railway track fasteners that can store disassembled nuts.

[0006] To solve the above-mentioned technical problems, this application provides a quick-release device for railway track fasteners, including a collection cylinder, a connecting pipe on one side of the collection cylinder, and a cover door connected to the other side of the collection cylinder by a hinge, and an avoidance hole is provided on the connecting pipe;

[0007] A connecting plate, wherein the connecting plate is disposed inside the collecting cylinder;

[0008] Nut hole, which is formed in the connecting plate, is used for inserting a nut;

[0009] A push-out hole is provided on one side of the connecting plate for one end of a bolt to pass through, and the push-out hole communicates with the nut hole;

[0010] A pusher assembly, which is disposed on the connecting plate, is used to push the disassembled nut.

[0011] In some embodiments, the feeding assembly includes a pair of fixed rods fixed to the connecting plate, a movable piece slidably connected to the pair of fixed rods, a fixed piece provided at one end of the pair of fixed rods, a fixed plate provided on the movable piece for passing through the feeding hole and the nut hole, and a return spring sleeved on the outer wall of each pair of fixed rods, one end of the return spring abutting against the movable piece, and the other end of the return spring abutting against the fixed piece.

[0012] In some embodiments, the inner diameter of the pusher hole is smaller than the inner diameter of the nut hole.

[0013] In some embodiments, the length of the fixing plate is greater than the depth of the nut hole.

[0014] In some embodiments, the diameter of the fixing plate is slightly smaller than the inner diameter of the push hole.

[0015] In some embodiments, the outer wall of the collection cylinder is provided with anti-slip texture.

[0016] In some embodiments, the outer wall of the cover is provided with a handle, and the outer wall of the collection tube has two viewing windows.

[0017] This utility model has at least the following beneficial effects:

[0018] 1. The pusher assembly, including a fixed rod, a fixed plate, a moving plate, a fixed plate, and a return spring, allows the nut to smoothly enter the nut hole when it is being disassembled. When the nut is completely removed from the bolt, the return spring pushes the nut in the nut hole into the collection cylinder, thus achieving automatic collection and storage of the nut.

[0019] 2. The anti-slip texture, handle, and viewing window enhance the stability and ease of operation, allowing operators to visually observe the storage status of nuts inside the collection cylinder and promptly clean them, thus avoiding the problem of insufficient internal space due to an excessive number of nuts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-5 This utility model provides a technical solution: a quick disassembly device for railway track fasteners, including a collection cylinder 1, a connecting pipe 4 on one side of the collection cylinder 1, a cover 2 connected to the other side of the collection cylinder 1 by a hinge, and an avoidance hole 5 on the connecting pipe 4.

[0030] Connecting plate 6 is disposed inside the collecting cylinder 1;

[0031] Nut hole 7 is provided on the connecting plate 6 for inserting a nut;

[0032] Push hole 9 is provided on one side of connecting plate 6 for one end of bolt to pass through, and push hole 9 is connected to nut hole 7;

[0033] The pusher assembly 100 is mounted on the connecting plate 6 and is used to push the disassembled nut.

[0034] The pusher assembly 100 includes a pair of fixed rods 101 fixed on the connecting plate 6. A movable piece 103 is slidably connected to the pair of fixed rods 101. A fixed piece 102 is provided at one end of the pair of fixed rods 101. A fixed plate 104 for passing through the pusher hole 9 and the nut hole 7 is provided on the movable piece 103. A return spring 105 is sleeved on the outer wall of the pair of fixed rods 101. One end of the return spring 105 abuts against the movable piece 103, and the other end of the return spring 105 abuts against the fixed piece 102.

[0035] The inner diameter of the push hole 9 is smaller than the inner diameter of the nut hole 7, so that one end of the nut can abut against one side of the push hole 9, preventing the nut from passing through the nut hole 7;

[0036] The length of the fixing plate 104 is greater than the depth of the nut hole 7, so that the fixing plate 104 can push the nut out of the nut hole 7;

[0037] The diameter of the fixing plate 104 is slightly smaller than the inner diameter of the push hole 9, so that the fixing plate 104 can slide smoothly in the push hole 9, while ensuring stable pushing of the nut.

[0038] The outer wall of the collection cylinder 1 is provided with anti-slip texture to increase stability during operation, prevent hand slippage, and improve operational safety;

[0039] When it is necessary to remove the nut mounted on the bolt, first, pass the clearance hole 5 on the connecting pipe 4 through one end of the bolt until one end of the bolt abuts against the fixing plate 104. Then push the collecting cylinder 1. At this time, one end of the bolt will push the fixing plate 104 to move. The fixing plate 104 drives the moving piece 103 to slide on the fixing rod 101. The moving piece 103 compresses the return spring 105 until the nut is completely inserted into the nut hole 7. At this time, rotate the collecting cylinder 1 to loosen the nut on the bolt. The nut will then move along the length of the bolt, and at the same time... With the nut located inside the nut hole 7, the collecting cylinder 1 will also move along the length of the bolt. When the nut is completely removed from the bolt, the return spring 105 pushes the moving plate 103 to return to its original position due to its own elastic force. The moving plate 103 drives the fixed plate 104 to move. The fixed plate 104 pushes the nut in the nut hole 7 into and stores it in the collecting cylinder 1, completing the removal and collection of the nut. Since one end of the bolt passes through the relief hole 5, the nut will not move to the position of the relief hole 5 when the fixed plate 104 pushes the nut, thus preventing the nut from sliding out of the relief hole 5.

[0040] After removing too many nuts, the operator can easily remove the nuts from the collection cylinder 1 by opening the cover door 2, which greatly improves work efficiency and reduces the complexity of operation.

[0041] Example 2

[0042] Please see Figure 6 This utility model provides a technical solution:

[0043] Unlike Example 1;

[0044] The outer wall of the cover 2 is equipped with a handle 3, and the outer wall of the collection cylinder 1 is provided with two viewing windows 20. The handle 3 makes it easy for the operator to open or close the cover 2, improving the convenience of operation. The viewing windows 20 allow the operator to directly observe the storage of nuts inside the collection cylinder 1, so as to clean the nuts in time and avoid the problem of insufficient internal space of the collection cylinder 1 due to too many nuts.
