Description

Technical field:

[0001] The present invention belongs to the technical field of railway freight car production, and in particular to the technical field of railway freight car whole vehicle painting, and specifically, is a bearing process trolley device for a railway freight car whole vehicle automatic painting line. Background technology:

[0002] There are two main types of vehicle spraying lines in the existing railway industry: single-station layout for single-in and single-out operation and multi-station layout for flow operation. Both methods use a simple trolley to carry the vehicle, and at the same time, platforms are set up on both sides of the vehicle to realize the painting of the vehicle body or internal paint. The vehicle is pulled by a winch or pushed by a tamping dock in the station to achieve vehicle entry and exit. The vehicle-carrying process trolleys used in these two methods are fixed center plate and side bearing support structures. The center plate support cannot be quickly adjusted in the height direction, and the side bearing support cannot be quickly adjusted in the height and width directions. Both require frequent switching and modification of the support device, which is time-consuming and labor-intensive, and increases the cost of use. In addition, there is no interface device that can be connected to the transmission device and the docking device in the automated vehicle painting line, and it cannot ensure that the vehicle can move smoothly and without collision during the transmission process. Because the wear of the vehicle-carrying process trolley wheels is inconsistent and inconsistent in the height direction, it is easy to cause the robot to collide with the side wall when spraying the vehicle. Therefore, it is necessary to design a new vehicle-carrying device for the body carrying and transmission of the vehicle automated spraying production line. Summary of the invention:
