A shield machine single hob tool changing manipulator

Abstract

A single-hob tool-changing manipulator for a shield machine belongs to the technical field of tunnel excavation construction equipment maintenance. The tool-changing manipulator can be used in conjunction with the telescopic mechanism to replace manual tool-changing operations to improve the tool-changing efficiency of the shield machine, protect the personal safety of construction personnel, and speed up the progress of tunnel excavation projects. The invention includes a shell, which is provided with a bolt disassembly and assembly module, a trapezoidal wedge disassembly and assembly module, a square wedge disassembly and assembly module, an axial rotation module and a hob disassembly and assembly fixing module; the trapezoidal wedge disassembly and assembly module The module includes a second fixed flange, which is fixed on the housing, and a first electromagnet is fixed on the second fixed flange; the square wedge disassembly and assembly module includes a disassembly and assembly telescopic part and a disassembly and assembly rotating part. part; the hob disassembly and fixation module includes a third hydraulic cylinder, the third hydraulic cylinder is fixed on the housing, and the piston rod of the third hydraulic cylinder is connected to the bolt fixed block.

Description

technical field [0001] The invention belongs to the technical field of tunnel excavation construction equipment maintenance, and relates to a shield machine tool changing manipulator, in particular to a shield machine single hob tool changing manipulator. Background technique [0002] The commonly used tool change methods of the shield machine are normal pressure tool change and under pressure tool change. The single hob tool change of the mud-water balance shield machine involved in the present invention is currently using manual tool change under pressure. During the tool change operation, construction workers need to enter the mud tank under pressure to check and replace the tool. This operation is not only difficult to construct, low in work efficiency, but also has a high risk factor, which is very prone to safety accidents. Under normal circumstances, construction personnel need to wear diving suits and corresponding protective measures before entering the cabin to wor...

Problems solved by technology

During the operation, when the cutter head needs to be rotated, all construction personnel must evacuate. At the same time, in order to avoid the intrusion of toxic gases, it is necessary to conduct air quality inspections at regular intervals, and construction personnel cannot continuously conduct inspections in the cabin for a long time. Tool change

[0003] During the entire tunnel construction process, multiple tool changes are required. Each tool change is cumbersome and time-consuming, which has a great impact on the overall construction progress. Therefore, designing and manufacturing a tool changing robot that can replace manual tool changing operations is of great importance. The personal safety of construction personnel, the efficiency of tool change operations and the progress of tunnel excavation will all be effectively improved
