AI Technical Summary
When replacing a faulty disc brake caliper in a subway car, the bogie needs to be lowered before disassembly and reassembly. This involves a lot of equipment and is complicated to operate, posing safety risks and affecting work efficiency.
A brake caliper disassembly and assembly auxiliary device was designed, including a base, a first support component, and a second support component. The device supports the brake caliper by means of bolts and the bottom of the push rod, and uses a lifting platform trolley for support and lifting to achieve the disassembly and assembly of the brake caliper.
The installation and removal of brake calipers are completed within the maintenance lane, avoiding the safety risks associated with shunting engineering vehicles and operating the gantry crane, thus improving operational efficiency and saving labor costs.
