Embodiment 1

[0031] see figure 1 with figure 2 , a mobile trolley overhaul device, comprising a track 1 and a mobile trolley 2 that can move longitudinally along the track 1, the mobile trolley 2 is dragged by a running mechanism provided on it, and the mobile trolley 2 includes a mobile The frame body 201, the mobile frame frame 202, the bracket 203 and the mobile frame drive mechanism 204, the mobile frame frame 202 is arranged on the bottom of the mobile frame body 201, and the bracket 203 is installed on the mobile frame. The inside of the bottom end of the frame 202 is used to hold up the maintenance vehicle. The bracket 203 is a telescopic screw nut. The nut can drive the supporting head 203 to perform lateral telescopic movement, and by adjusting the telescopic lead screw nut, the lifting requirements of vehicles of different widths can be met. The support head 203 and the mobile frame carrying frame 202 are movably installed on the inner side of the mobile frame body 201, and th...

Embodiment 2

[0041] The structure and composition of the overhaul device in embodiment 2 are basically the same as those in embodiment 1, and the difference is that the platform elevating and lifting device 3022 is a connecting rod, and the upper end of the connecting rod is connected to the lifting platform of the platform. The guide device 3021 is connected, and the lower end of the connecting rod is connected with the carrying frame 202 of the mobile trolley. Using the connecting rod, the platform 301 and the carrying frame 202 of the mobile trolley can be lifted and lowered at the same time.

Abstract

The invention relates to a movable vehicle lifting type maintenance device for railways. The movable vehicle lifting type maintenance device comprises a rail and a movable vehicle lifting jack which can move longitudinally along the rail, wherein the movable vehicle lifting jack comprises a movable vehicle lifting frame body, a movable vehicle lifting bearing framework, a supporting head and a movable vehicle lifting driving mechanism, the movable vehicle lifting bearing framework is arranged on the bottom of the movable vehicle lifting frame body, the supporting head is installed on the inner side of the bottom end of the movable vehicle lifting bearing framework, and the movable vehicle lifting driving mechanism is used for driving the movable vehicle lifting bearing framework and the supporting head to rise and fall along the movable vehicle lifting frame body. The movable vehicle lifting type maintenance device further comprises a lifting maintenance platform, wherein the lifting maintenance platform comprises a platform body, a platform lifting device, a platform longitudinal stretching device and a platform transverse stretching device. According to the movable vehicle lifting type maintenance device, lifting, longitudinal stretching and transverse stretching of the platform can be controlled for operation, and maintenance and replacement of electrical devices on the bottom and the top of a vehicle can be achieved at the same time on the same station.

Description

technical field [0001] The invention relates to a maintenance equipment for railway locomotives, in particular to a maintenance device for railway mobile carriages. Background technique [0002] Commonly used equipment for disassembly and maintenance of railway vehicle bogies and parts includes mobile cranes, pit (fixed) cranes and fixed maintenance platforms. [0003] The pit-type car crane is used for the maintenance of EMUs, high-speed trains, high-power locomotives or urban rail vehicles that do not disintegrate the entire train, including the replacement of vehicle bogies, the maintenance of electrical facilities under the car body and electrical facilities on the roof and replacement work. Chinese Patent No. CN102718172 discloses a lifting unit for a compatible pit-type locomotive body. When the lifting unit is used for lifting the vehicle, the whole train is first synchronously lifted to a certain height by the bogie lifting unit, and then Remove the bogie, and then...
