Description

Technical Field

[0001] This utility model belongs to the field of rail transportation technology, specifically relating to a rail transportation anti-slip device. Background Technology

[0002] Utility model patent CN221737815U discloses a track transport anti-track movement device, including a locking screw, a locking seat, and a locking pressure iron. The lower part of the locking screw has a cuboid locking screw base. The upper plate of the locking seat has a strip-shaped square hole, the length and width of which are greater than the length and width of the locking screw base, while the width of the strip-shaped square hole is less than the length of the locking screw base. The bottom of the upper plate of the locking seat has two slots, symmetrically arranged opposite the strip-shaped square hole, with the length direction of the slots perpendicular to the strip-shaped square hole. The locking screw base is movably embedded in the two slots. After the locking screw passes through the gap between the two tracks and the locking pressure iron, it is locked with a nut. The locking pressure iron overlaps the upper surfaces of the two tracks, and the bottom surfaces of the two tracks contact the upper surface of the locking seat. The distance between the lower ends of the two slots and the inner surface of the lower plate of the locking seat is greater than the height of the locking screw base. This utility model reduces the probability of track movement caused by screw loosening, improves fastening reliability, enhances transport safety, and facilitates loading and unloading.

[0003] However, the above-mentioned mechanism has the following problems: the nut is only prevented from slipping by a double nut structure with a rubber pad. This method can still cause the nut to loosen by self-spinning when it is vibrated; in addition, the track lacks left and right limiters, which makes the track prone to inward translation and sliding relative to the anti-slip device, affecting the safety of transportation. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a track transport anti-slip device, which solves the problems that the nut of the track transport anti-slip device will spin loose when subjected to vibration, and that the track is prone to translational slippage relative to the anti-slip device, affecting the safety of transport.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a track transport anti-slip device, comprising a base, wherein the side of the base is provided with a bolt head groove and a rod groove for a sliding insert screw, the screw being threadedly connected to a nut in a self-locking assembly, the nut being slidably installed inside a nut sleeve, and a spring washer being installed between the nut and the nut sleeve, wherein the upper end face teeth formed on the bottom surface of the nut sleeve are engaged with the lower end face teeth, the lower end face teeth being installed on the top surface of a pressure plate, the pressure plate and the base being respectively clamped on the upper and lower sides of a rail, one side of the upper flange of the rail abutting against the flange of the connecting pressure plate, and the other side of the lower flange of the rail abutting against a connecting limiting baffle, the limiting baffle being installed on the base.

[0006] The beneficial effects of this utility model are as follows: the limiting baffle, together with the flange of the pressure plate, limits the two sides of the rail to prevent the rail from sliding between the base and the pressure plate; the design of the spring washer in the self-locking assembly with the end face teeth effectively prevents the nut from rotating and loosening due to vibration.

[0007] To prevent the screw from rotating on the base;

[0008] As a further improvement to the above technical solution: the base is composed of a lower base plate and an upper base plate welded together, the bolt head groove and the rod groove are respectively opened on the lower base plate and the upper base plate, the two opposite sides of the head end of the screw slide against the inner wall of the bolt head groove, and the side of the rod is slidably connected to the inner wall of the rod groove.

[0009] The beneficial effects of this improvement are: the bolt head groove and the rod groove provide a limiting function, allowing the screw to be easily installed on the base. Combined with the use of the self-locking component and the pressure plate, the rail is securely locked, preventing the rail from shifting during transportation.

[0010] To further improve the stability of the connection between the pressure plate and the base;

[0011] As a further improvement to the above technical solution: the number of screws is not less than two.

[0012] The beneficial effects of this improvement are: two or more screws can limit the angle between the base and the pressure plate, further improving the stability of the base and pressure plate in clamping the rail.

[0013] To facilitate the installation of the nut sleeve;

[0014] As a further improvement to the above technical solution: the nut sleeve is provided with a through hole for a suitable connecting screw.

[0015] The beneficial effects of this improvement are: the nut sleeve can be slidably fitted onto the outside of the screw, enabling convenient installation and removal.

[0016] In order for the spring washer to effectively support the nut;

[0017] As a further improvement to the above technical solution: the diameter of the through hole for the connecting screw on the nut sleeve is not greater than the inner diameter of the spring washer.

[0018] The beneficial effect of this improvement is that the spring washer can generate elastic deformation to support the nut sleeve to be firmly pressed on the lower end face teeth, thereby locking the rotation angle of the nut.

[0019] To ensure that the nut sleeve drives the nut to rotate stably;

[0020] As a further improvement to the above technical solution: the top surface of the nut sleeve is provided with a regular hexagonal groove structure adapted to install the nut.

[0021] The beneficial effect of this improvement is that after the nut is filled inside the nut sleeve, it can rotate stably and synchronously with the nut sleeve.

[0022] For easy rotation of the nut sleeve;

[0023] As a further improvement to the above technical solution: the nut sleeve has a regular hexagonal prism structure.

[0024] The beneficial effect of this improvement is that the nut sleeve itself can be used as a large nut, making it convenient for operators to turn the nut sleeve with a wrench.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 5: A rail transport anti-slip device includes a base 1. The side of the base 1 has a bolt head groove 14 and a rod groove 15 for a sliding insert screw 3. The screw 3 is threadedly connected to a nut 41 in a self-locking assembly 4. The nut 41 is slidably installed inside a nut sleeve 42, and a spring washer 44 is installed between the nut 41 and the nut sleeve 42. The upper end face teeth 421 formed on the bottom surface of the nut sleeve 42 mesh with the lower end face teeth 43. The lower end face teeth 43 are installed on the top surface of a pressure plate 2. The pressure plate 2 and the base 1 are respectively clamped on the upper and lower sides of a rail 5. One side of the upper flange of the rail 5 is attached to the pressure plate 2. The flange of the rail 5 is connected to the limiting baffle 13 on the other side of the lower flange. The limiting baffle 13 is installed on the base 1. The limiting baffle 13, together with the flange of the pressure plate 2, limits the two sides of the rail 5 to prevent the rail 5 from sliding between the base 1 and the pressure plate 2. The design of the spring washer 44 in the self-locking assembly 4 with the end face teeth effectively prevents the nut 41 from rotating and loosening due to vibration. The base 1 is composed of a lower base plate 11 and an upper base plate 12 welded together. The bolt head groove 14 and the rod groove 15 are respectively opened on the lower base plate 11 and the upper base plate 12. The two opposite sides of the head end of the screw 3 slide against the bolt head groove. The inner wall of the bolt head groove 14 and the inner wall of the rod groove 15 of the bolt head groove 14 and the rod groove 15 provide a limiting function, so that the bolt 3 can be easily installed on the base 1. With the use of the self-locking component 4 and the pressure plate 2, the rail 5 is securely locked to prevent the rail 5 from moving during transportation. There are no less than two bolts 3. Two or more bolts 3 can limit the angle between the base 1 and the pressure plate 2, further improving the stability of the base 1 and the pressure plate 2 in clamping the rail 5. The nut sleeve 42 has a through hole that is suitable for connecting the bolt 3. The nut sleeve 42 can be slidably fitted on the outside of the bolt 3. The nut sleeve 42 is designed for convenient installation and removal. The diameter of the through hole for the connecting screw 3 on the nut sleeve 42 is no larger than the inner diameter of the spring washer 44. The spring washer 44 can generate elastic deformation to support the nut sleeve 42 to be firmly pressed against the lower end face teeth 43, thereby locking the rotation angle of the nut 41. The top surface of the nut sleeve 42 is provided with a regular hexagonal recess structure adapted to install the nut 41. After the nut 41 is filled into the inner side of the nut sleeve 42, it can rotate stably and synchronously with the nut sleeve 42. The nut sleeve 42 has a regular hexagonal prism structure and can itself be used as a large nut, allowing the operator to easily rotate the nut sleeve 42 with a wrench.

[0035] The working principle of this technical solution is as follows: Two steel rails 5 are installed side by side, with one side of the lower flange of each rail 5 abutting the side of the limiting baffle 13. Then, the screw 3 is slidably inserted into the bolt head groove 14 and the rod groove 15 from one side of the base 1, so that the two opposite sides of the screw 3 head slide against the inner wall of the bolt head groove 14. Then, the pressure plate 2 is installed on top of the two steel rails 5, so that the sides of the rails 5 slide against the inner wall of the flange of the pressure plate 2, and the rod of the screw 3 passes through the inner hole of the lower end face tooth 43. Then, the operator inserts the spring washer 4. 4. Slide the nut 41 into the nut sleeve 42, hold the nut sleeve 42 and rotate the nut 41 on the screw 3. This causes the nut 41 to move the spring washer 44 and the nut sleeve 42 downwards. When the upper end face tooth 421 and the lower end face tooth 43 engage with each other, the continuously rotating nut 41 compresses the spring washer 44, causing the spring washer 44 to undergo elastic deformation. At the same time, the nut sleeve 42 moves up and down rapidly and repeatedly during the process of the upper end face tooth 421 engaging and disengaging with the lower end face tooth 43, causing the spring washer 44 to deform repeatedly until the nut 41 is tightened to a suitable level.
