Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic manipulators, and more specifically, particularly relates to a suspended hydraulic manipulator. Background Technique

[0002] A manipulator is an automatic mechanical device, and its main function is to operate tools and workpieces. Currently, manipulators can be divided into hydraulic manipulators, pneumatic manipulators, and electric manipulators. When some hydraulic manipulators are in use, they are usually suspended on a moving frame.

[0003] When a traditional suspended hydraulic manipulator is in use, since the hydraulic cylinder on the suspended hydraulic manipulator is prone to heat up after long-term use, the service life of the hydraulic cylinder will be reduced. Moreover, when the traditional suspended hydraulic manipulator is disassembled and repaired from the moving frame, since the manipulator and the moving frame are connected by a large number of bolts, tools are required for disassembly during disassembly, thereby reducing the convenience of the suspended hydraulic manipulator during disassembly and repair.
