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

Abstract

The invention discloses a single-hobbing-cutter changing manipulator of a shield tunneling machine and belongs to the technical field of maintenance of tunneling construction equipment. The single-hobbing-cutter changing manipulator can be used in cooperation with a telescopic mechanism to replace the manual cutter changing operation, thereby improving the cutter changing efficiency of the shield tunneling machine, ensuring personnel safety of constructors and accelerating the progress of the tunneling engineering. The single-hobbing-cutter changing manipulator comprises a shell, wherein the shell is provided with a bolt assembling and disassembling module, a trapezoidal wedge assembling and disassembling module, a square wedge assembling and disassembling module, an axial rotary module and a hobbing cutter assembling and disassembling fixing module; the trapezoidal wedge assembling and disassembling module comprises a second fixing flange fixed to the shell, and a first electromagnet is fixed to the second fixing flange; the square wedge assembling and disassembling module comprises an assembling and disassembling telescopic part and an assembling and disassembling rotary part; and the hobbing cutter assembling and disassembling fixing module comprises a third hydraulic cylinder fixed to the shell, and a piston rod of the third hydraulic cylinder is connected with a bolt fixing clamping position 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...
