[0026] The solution of this embodiment provides a support device for railway freight car maintenance, including a carriage 1, a hanging plate 5, an auxiliary member, and a support mechanism 3. A wheel body 2 capable of moving the carriage 1 is provided at the lower part of the carriage 1; the support mechanism 3 is provided at the lower part of the carriage 1 and is located between the wheel bodies 2. Among them, the support mechanism 3 is symmetrically arranged left and right, and at least two support mechanisms 3 are provided. The carriage 1 is lifted by the support mechanism 3; the support mechanism 3 includes a first fixed seat 301 and a hydraulic jack 303. The first fixed seat 301 and the hydraulic jack 303 are hinged by a connecting block 302, so that the hydraulic jack 303 can be perpendicular to the ground under its own gravity. The end of the telescopic rod 304 of the hydraulic jack 303 is hinged with a top seat 305, and the force is received by contacting the ground through the top seat 305; the auxiliary member is provided on one side of the hydraulic jack 303 and is hinged to the side surface of the hydraulic jack 303; the hanging plate 5 is fixedly provided at the lower part of the carriage 1 and is fixed on the side close to the auxiliary member. The cross section of the hanging plate 5 is in an "L" shape.
[0027] It should be further noted that the auxiliary member includes a fixing piece 306 and a second fixing seat 308. The fixing piece 306 and the second fixing seat 308 are both arranged on the side surface of the hydraulic jack 303. A preset distance is provided between the fixing piece 306 and the second fixing seat 308, and the fixing piece 306 is arranged on one side of the second fixing seat 308. The auxiliary member further includes an auxiliary piece 309. One end of the auxiliary piece 309 is hinged to the second fixing seat 308, and the middle part of the auxiliary piece 309 is connected to the fixing piece 306 through a spring 307. The auxiliary piece 309 is pulled towards the hydraulic jack 303 by the pulling force of the spring 307, so as to cooperate with the hanging plate 5 for fixing.
[0028] It should be further noted that the auxiliary member includes a first hole 3091 and a second hole 3092. The first hole 3091 is arranged in the middle part of the auxiliary piece 309. One end of the spring 307 is fixed to the first hole 3091, and the second hole 3092 is arranged at the end of the auxiliary piece 309. The second hole 3092 can be used to fix the entire support mechanism 3 through bolts.
[0029] It should be further noted that a card slot for being stuck on the hanging plate 5 is arranged on one side of the auxiliary member close to the first hole 3091. An arc surface is arranged between the card slot and the first hole 3091. The arrangement of the arc surface facilitates the buckling of the auxiliary piece 309 and the hanging plate 5.
[0030] Working principle of the present utility model:
[0031] During use, in the present utility model, a plurality of suspended hydraulic jacks 303 are arranged at the lower part of the carriage 1. An auxiliary member is arranged on one side of the hydraulic jack 303. The auxiliary piece 309 that can retract the suspended hydraulic jack 303 is facilitated to use through the auxiliary member. At the same time, a scraping plate is arranged on one side of the auxiliary piece 309. Through the card slot of the auxiliary piece 309, when it is necessary to lower the hydraulic jack 303, only one end of the auxiliary piece 309 needs to be pulled, so that the hydraulic jack 303 naturally drops. Then, the hydraulic jack 303 is driven to jack up the carriage 1 for maintenance. After use, only the end of the retraction of the auxiliary piece 309 or the hydraulic jack 303 needs to be pulled again, so that the card slot of the auxiliary piece 309 can be stuck on the scraping plate. Through the pulling force of the spring 307 and the gravity of the entire hydraulic jack 303, the hydraulic jack 303 can be firmly fixed. At the same time, an arc surface is arranged between the card slot and the first hole 3091. Through the arc surface, it is convenient for the hook of the auxiliary piece 309 to be better stuck on the scraping plate, so as to achieve the effects of convenient storage and convenient use.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
