[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0025] A manual adjustment device for a railway parking brake cylinder provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] Combination Figure 1-3 As shown, the utility model provides a manual adjustment device for a railway parking brake cylinder, comprising a brake module 100 and a labor-saving module 200, wherein the brake module 100 comprises a parking cable 110, a cable sleeve 120 sleeved on one end of the parking cable 110, a hose 130 movably sleeved on the outside of the parking cable 110, a plurality of connectors 140 enclosed on one end of the hose 130, and two locking sleeves 150 sleeved on the outside of the hose 130;

[0028] The labor-saving module 200 includes a transverse plate 210 connected between two locking sleeves 150, a support plate 220 connected to the top of the transverse plate 210, a pull rope 230 connected to the support plate 220, a fixed pulley 240 attached to the bottom of the pull rope 230, a support frame 280 movably sleeved on the bottom of the fixed pulley 240 and connected to the transverse plate 210, a movable pulley 250 attached to the top of the pull rope 230, a hook 260 provided at the bottom of the pull rope 230 and movably connected to the movable pulley 250, and a rope body 270 connected between the rope loop 120 and the hook 260.

[0029] Furthermore, a plurality of connectors 140 are arranged in a ring shape at equal intervals, and a plurality of threaded holes are formed on the connector 140 , through which the hose 130 can be firmly connected to the external brake cylinder.

[0030] Furthermore, the cross plate 210 and the support plate 220 are made of the same material. The support plate 220 is perpendicular to the cross plate 210 and is made of the same material, which reduces the difficulty of material selection when manufacturing the cross plate 210 and the support plate 220.

[0031] Furthermore, the pull rope 230 is arranged on the top of the rope body 270, and both are made of metal material. The pull rope 230 and the rope body 270 made of metal material reduce the probability of the two being broken.

[0032] Furthermore, the support frame 280 is configured to be H-shaped, and the rope body 270 transversely passes through the bottom of the support frame 280 . This shape design can limit the guidance of the rope body 270 and prevent the rope body 270 from deviating.

[0033] Embodiment 2:

[0034] Combination Figure 1 and Figure 3 As shown, on the basis of the first embodiment, the parking cable 110 is made of a plurality of steel wires bundled together, and two adjacent steel wires are bonded to each other. This structural design can reduce the probability of the parking cable 110 breaking during use.

[0035] Embodiment three:

[0036] Combination Figure 1-2 As shown, in the above embodiment, a plurality of annular grooves are provided on the outside of the hose 130 , and the plurality of annular grooves are arranged in a row at equal intervals. The annular grooves can improve the heat dissipation of frictional heat when the parking cable 110 rubs against the hose 130 .

[0037] The working principle and use process of the utility model are as follows: when the device is put into actual use, the parking cable 110 is connected to the external brake cylinder through the threaded hole on the locking sleeve 150. Then, during manual braking, the user pulls the pull rope 230, and then the fixed pulley 240 and the movable pulley 250 cooperate to reduce the pulling force of the rope body 270 and the parking cable 110, thereby relieving the parking brake.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate 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 claims and their equivalents.
