Description

General crashproof technology platform truck of railway freight car Technical Field The invention belongs to railway wagon manufacturing auxiliary equipment, and particularly relates to a general anti-collision process trolley for a railway wagon. Background In order to avoid damage and pollution of the bogie in the subsequent processes of vehicle sandblasting and paint coating, the conventional railway wagon generally adopts a process that the railway wagon falls on a process trolley, and the railway wagon is transferred to the processes of vehicle sandblasting and paint coating in a traction or manual pushing mode, and is replaced by the bogie for brake hook slow assembly after the operation is completed. Meanwhile, as the car body steel structure procedure does not assemble the car coupler yet, in order to avoid car body damage caused by collision during the work of the transfer procedure and the sand blasting and painting stations after the car body falls down the process trolley, an anti-collision device is usually additionally arranged on the impact seats at the two ends of the car body underframe. As shown in fig. 1, the problem of using an existing process trolley and a collision avoidance device to tamper a vehicle is that: a. The existing process trolley is generally formed by modifying a scrapped cast steel three-piece bogie, and adopts a fixed center plate and a side bearing supporting structure. In order to ensure enough working space for the procedures of blasting the car body and painting the car, the car body is usually raised to a proper height (the height is too low, no enough working space exists, the height is too high, and the operation is inconvenient and unsafe) by adopting a mode of welding a supporting device on a side frame of a process trolley. Because of different types of railway wagons, the external dimensions of the railway wagons and the heights of the bottoms of the railway wagons from the ground are different, the heightened process trolley has no universality, and the supporting device needs to be frequently switched and modified, so that the railway wagons are labor-consuming and time-consuming, have long preparation period and increase the use cost. B. the existing technological trolley is borne by a center panel and is about 2 meters away from the end of the vehicle. In order to prevent the collision of vehicles in the vehicle sequence process, anti-collision devices are additionally arranged at two ends of the vehicle body. The anti-collision device belongs to a special tool, firstly, a large number of anti-collision devices are required to be manufactured when vehicles from a steel structure of the vehicle body to the procedures of sand blasting and painting of the vehicle body are in a lot, so that the manufacturing cost is increased, secondly, the anti-collision device is taken down when the vehicle is assembled with a coupler and is then pounded back to the steel structure of the vehicle body for reuse, so that the logistics pounding cost is increased, thirdly, the impact seats of different vehicle types are different in structure, the additionally arranged anti-collision device is required to be designed according to the vehicle types, the universality is not achieved, fourthly, a large number of anti-collision devices are required to be stored and managed in a special place, so that the management cost is increased, and thirdly, the anti-collision device is deformed due to collision after long-term use, so that the maintenance cost is increased, and if the anti-collision device is not maintained in time, the normal transfer of the vehicle is affected, so that the safety quality risk is caused. Disclosure of Invention The invention aims to provide a universal anti-collision process trolley for a railway wagon, which solves the problems of non-universality and inconvenience of the existing process trolley. The aim of the invention is achieved by the following technical scheme: the utility model provides a general crashproof technology platform truck of railway freight car, includes general platform truck body, and general platform truck body bears in the middle beam inner chamber of railway freight car, bears between the front and back slave board seat of middle beam, and the outer end of general platform truck body installs buffer crashproof device additional; the universal trolley body comprises a positioning cushion block, an adjusting cushion block, a mounting seat and a travelling trolley, the positioning cushion block bears the railway wagon, the positioning cushion block is detachably mounted on the adjusting cushion block, the adjusting cushion block is detachably mounted on the mounting seat, the mounting seat is fixed on the travelling trolley, and the buffering anti-collision device is mounted on the travelling trolley. Furthermore, the positioning cushion block is formed by welding a bottom plate and a positioning block, the bottom plate and the adjusti
