AI Technical Summary
The installation and removal of existing hydraulic hoses inside the boom are time-consuming and labor-intensive, especially when both ends are inside the boom and need to be fixed with bolts, which makes maintenance inconvenient.
A hydraulic hose connection mechanism for boom is designed, including a connecting bracket, first and second hoses, rigid pipe assembly and rigid pipe support. Limiting is achieved by the cooperation of the insert plate and the slot, and the top plate contacts the rigid pipe support for fixation, avoiding bolt fixation.
It enables rapid installation and removal of hydraulic hoses, simplifies the operation process, and improves maintenance efficiency.
