Description

Technical Field

[0001] The utility model relates to the technical field of quay crane brake maintenance, in particular to a quay crane brake push rod bearing disassembly device. Background Art

[0002] High-speed brakes are the primary braking device used during the operation of various quay crane mechanisms. They provide the dominant braking function within the crane's key moving mechanisms and guarantee safe operation. Their importance and frequent use during quay crane operations inevitably lead to varying degrees of wear and damage. Disassembly of high-speed brakes is particularly difficult due to their multi-layered internal structure. The bearings within the push rods, in particular, lack suitable disassembly equipment due to their specialized mounting requirements, making maintenance inefficient and labor-intensive.

[0003] In the common repair of high-speed brake pushrods for quay cranes, the brake pushrod bearings are primarily disassembled using spacers or extension blocks. External force is applied to the bearings, which then vibrate and dislodge them. This percussive vibration process can easily cause secondary damage to critical components such as the pushrod shaft and rotor, rendering the entire pushrod useless. The disassembly process is time-consuming and labor-intensive. Unsuccessful removal of a single bearing can take over an hour, requiring two people to apply intermittent force. Utility Model Content
