Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of railway freight car 120 valve module, and particularly relates to a process equipment for modular assembly of existing railway freight car 120 valve module. BACKGROUND

[0002] At present, the process equipment for modular assembly of railway freight car 120 valve has the following shortcomings:

[0003] 1) The first installation method for the main module assembly of 120 valve is that the trolley is transported to the bottom of the car, and then the valve, the intermediate body, the double-chamber air cylinder, the auxiliary air cylinder and other components are manually lifted and adjusted for installation, and finally the brake pipe system between the components is installed. The whole process is time-consuming and laborious, and the installation period is long. Moreover, due to the cumulative error between the components, the components are prone to be assembled with great force, the labor intensity is large, the production efficiency is low, and the second installation method is that the whole is manually carried and lifted for installation after being assembled on the ground. Since the valves and air cylinders are not positioned during assembly, they are in a free state, which causes the relative position of the installation surface to be inconsistent with the positioning surface of the moving platform, and even the installation hole is misaligned, which causes the components to be assembled with great force and affects the assembly quality of the brake system.

[0004] 2) The assembly of the derailment valve module in the railway freight car 120 valve is that the workers pre-assemble the derailment valve on the platform and then manually carry it to the corresponding installation position at the bottom of the vehicle for installation. The existing installation platform is only a flat plate on which the derailment valve is placed, and the end components of the derailment valve cannot be fixed left and right. Moreover, the manual carrying after installation is time-consuming and laborious, and the workload of the workers is heavy.

[0005] 3) The assembly of the main pipe module in the railway freight car 120 valve is that the workers pre-assemble the main pipe module on the platform and then manually carry it to the corresponding installation position at the bottom of the vehicle for installation. The existing main pipe module installation platform is only a flat plate on which the main pipe module is placed, and the straight pipe of the main pipe module cannot be fixed left and right. Therefore, when the angle plug door is tightened and installed at the end of the straight pipe, it is inconvenient to operate, and one worker needs to hold the straight pipe and the other worker needs to tighten the angle plug door, which increases the labor cost.

[0006] 4) The pipe transportation of the railway freight car air brake system is manually pushed by ordinary trolleys from the warehouse to the workshop or from the workshop to the bottom of the vehicle. Since the pipes are many and heavy, only the trolleys are used to repeatedly transport and install the pipes, which is time-consuming and laborious. Moreover, since the front side of the trolley is provided with a baffle, the pipe ends are prone to be knocked during the back-and-forth transportation, which causes the pipe butt joint installation to fail. SUMMARY

[0007] The present application aims to provide a railway freight car 120 valve modular assembly process equipment, which is convenient to install, saves time and labor, solves the problem that the current 120 valve module assembly is transported to the bottom of the car by a trolley and then installed manually by lifting individual components, which leads to strong assembly of components, high labor intensity and low production efficiency, solves the problem that the existing derailment valve installation platform is a whole flat plate on which the derailment valve is placed and which cannot fix the end components of the derailment valve left and right, leading to inconvenient installation, and solves the problem that manual handling of the assembled derailment valve module leads to time-consuming and labor-intensive, and solves the problem that the existing main pipe module installation platform cannot fix the straight pipe of the main pipe module left and right, leading to inconvenient operation when tightening and installing the corner cock door at the end of the main pipe.
