DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a hydraulic shock absorber for railway track, comprising a bracket 1 and a disassembly mechanism 2, wherein the disassembly mechanism 2 is arranged on one side of the surface of the bracket 1, and the installation mechanism 3 is arranged on one end of the bracket 1;

[0022] The disassembly mechanism 2 includes a first mounting groove 201, a thread groove 202, a second mounting groove 203, a shock absorber body 204, a sub-gear 205, a main gear 206, a limiting groove 207, a rotating shaft 208, a limiting block 209 and a protective pad 210. The first mounting groove 201 is provided on one side of the surface of the bracket 1, the thread groove 202 is provided on one end of the bracket 1, the second mounting groove 203 is provided on one side of the surface of the bracket 1, the shock absorber body 204 is connected to the internal thread of the thread groove 202, the sub-gear 205 is installed on one side of the surface of the second mounting groove 203, the main gear 206 is installed inside the second mounting groove 203, the limiting groove 207 is provided on one side of the surface of the shock absorber body 204, one end of the main gear 206 is fixedly connected to the rotating shaft 208, and the surface of the rotating shaft 208 is engaged with the limiting block 210. 09, a protective pad 210 is installed on the other side of the limit block 209. Through the arrangement of the first installation groove 201, the threaded groove 202, the second installation groove 203, the shock absorber body 204, the secondary gear 205, the main gear 206, the limit groove 207, the rotating shaft 208, the limit block 209 and the protective pad 210, when in use, when it is necessary to inspect and replace the hydraulic shock absorber, rotate the limit block 209, screw the limit block 209 and the protective pad 210 thereon out of the limit groove 207, when the limit block 209 and the protective pad 210 are completely screwed out of the limit groove 207, rotate the handle on the shock absorber body 204, and then turn the shock absorber body 204 out of the threaded groove 202, when the shock absorber body 204 is completely turned out of the threaded groove 202, take out the shock absorber body 204, and then start the inspection and maintenance work.

[0023] Furthermore, the positions of the first mounting groove 201 and the threaded groove 202 are relatively straight, and one end of the shock absorber body 204 is embedded in the first mounting groove 201. Through the setting of the first mounting groove 201 and the threaded groove 202, the first mounting groove 201 can fix the top of the shock absorber body 204, thereby preventing the lateral force during operation from affecting the normal use of the shock absorber body 204. The threaded groove 202 fixes the shock absorber body 204 on the bracket 1, thereby ensuring the normal operation of the upper shock absorbing mechanism.

[0024] Furthermore, eight groups of sub-gears 205 are provided, and the sub-gears 205 are meshed with the main gears 206. Through the setting of the sub-gears 205 and the main gears 206, during the operation of the shock absorber body 204, the rotating shaft 208 drives the main gear 206 to rotate, and the main gear 206 drives multiple groups of sub-gears 205 to rotate, thereby limiting the rotation speed of the rotating shaft 208 and the limit block 209, providing a second layer of protection for fixing the shock absorber body 204, and preventing the limit block 209 from rotating out of the limit groove 207, thereby affecting the normal operation of the shock absorber body 204.

[0025] Furthermore, one end of the limit block 209 is embedded in the limit groove 207, and one end of the protection pad 210 is embedded in the limit groove 207. Through the setting of the protection pad 210, during the operation of the shock absorber body 204, the protection pad 210 can provide effective protection for the limit block 209 to prevent the force on the shock absorber body 204 from crushing the limit block 209. At the same time, the protection pad 210 and the limit groove 207 have a relatively large friction coefficient, thereby limiting the rotation speed of the limit block 209, providing a third layer of protection for fixing the shock absorber body 204, and preventing the shock absorber body 204 from detaching from the bracket 1.

[0026] Furthermore, the second mounting groove 203 passes through one side of the bracket 1, and one end of the rotating shaft 208 is embedded in the second mounting groove 203. Through the setting of the rotating shaft 208, one end of the rotating shaft 208 is connected to the main gear 206, and the other end is connected to the limit block 209. Then, through the rotation of the sub-gear 205 and the main gear 206, the rotation speed of the limit block 209 is effectively limited, thereby preventing the shock absorber body 204 from falling off.

[0027] Furthermore, the mounting mechanism 3 includes a fixing plate 301, a connecting hole 302, a shock absorbing block 303, a protective plate 304 and a bolt 305. The surface of the bracket 1 is connected to the fixing plate 301, a connecting hole 302 is provided on one side of the surface of the fixing plate 301, a shock absorbing block 303 is installed at one end of the fixing plate 301, a protective plate 304 is attached to one end of the fixing plate 301, and a bolt 305 is embedded inside the connecting hole 302. Through the arrangement of the fixing plate 301, the connecting hole 302, the shock absorbing block 303, the protective plate 304 and the bolt 305, when in use, first put the bracket 1 into a suitable installation position, then insert the bolt 305 into the connecting hole 302 and the protective plate 304, and then tighten the bolt 305 to fix the bracket 1.

[0028] Furthermore, two groups of shock-absorbing blocks 303 are provided, and one end of the shock-absorbing block 303 is embedded in the inside of the protective plate 304. Through the setting of the shock-absorbing block 303, during the long-term operation of the train, the shock-absorbing block 303 can reduce the energy generated by shock, impact or vibration during the movement of the train, and can absorb and disperse the energy from external forces, thereby reducing the vibration and impact of the bracket 1, and ensuring the normal operation of the shock absorber body 204.

[0029] Working principle: first, place the bracket 1 in a suitable installation position, then insert the bolt 305 into the connecting hole 302 and the protective plate 304, and then tighten the bolt 305 to fix the bracket 1. When the hydraulic shock absorber needs to be inspected and replaced, turn the limit block 209, and screw the limit block 209 and the protective pad 210 thereon out of the limit groove 207. When the limit block 209 and the protective pad 210 are completely screwed out of the limit groove 207, turn the handle on the shock absorber body 204 to turn the shock absorber body 204 out of the threaded groove 202. When the shock absorber body 204 is completely turned out of the threaded groove 202, take out the shock absorber body 204 and start inspection and maintenance work.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
