Hob Disassembly Mechanism Applicable to Shield Tool Changer Robot

Abstract

The invention provides a hobbing cutter dismounting and mounting mechanism suitable for a shield tool changing robot. The mechanism comprises a cutter shaft mounting base, a cutter shaft of a hobbingcutter and the cutter shaft mounting base are fixedly connected, the cutter shaft mounting base is detachably connected with a cutter box on a shield tunneling machine cutter disc, a locking part is mounted on the cutter shaft mounting base, a middle sliding block and side sliding blocks are mainly included, vertical moving is achieved through the middle sliding block, the side sliding blocks aredriven to horizontally move, locking and loosening processes of the cutter shaft mounting base and the hobbing cuter and an inner cutter box can be finished, limited inner space of the cutter box andthe hobbing cutter heavy load characteristics can be considered at the same time, the hobbing cutter dismounting and mounting mechanism which is compact and reliable is provided, through cooperation of the cutter shaft mounting base, the middle sliding block and the side sliding blocks, the reliable connection and safe dismounting and mounting of the hobbing cutter and the cutter box can be achieved, manual tool replacing work is replaced, the tool replacing frequency is improved, and the shield construction risks are reduced.

Description

technical field [0001] The invention relates to the field of shield tunneling equipment, in particular to a hob disassembly mechanism suitable for a tool changing robot in shield tunnel engineering. Background technique [0002] The shield machine is a special construction machine for tunneling, and has broad application prospects in the construction of tunnels such as subways, railways, highways, and municipalities. The hob is the core component of the shield machine. The complex and changeable geological conditions lead to serious failure of the hob. If it is not replaced in time, it will increase the overall energy consumption of the shield machine and delay the construction period. Therefore, tool change is an inevitable process in the shield tunneling process. At present, some shield constructions at home and abroad still use manual tool change, which is difficult, technically demanding, time-consuming, and risky in high-pressure and narrow working spaces. "Machine re...

Problems solved by technology

At present, some shield constructions at home and abroad still use manual tool change, which is difficult, technically demanding, time-consuming, and risky in high-pressure and narrow working spaces. "Machine replaces man" tool change operation, and the premise of the tool change robot to realize the automatic replacement of the hob is to have a hob disassembly mechanism for disassembling and assembling the hob

[0003] Due to the large volume and weight of the hob, the path of disassembly and assembly is relatively complicated, which puts forward a higher requirement for the disassembly mechanism of the hob. The automation degree and carrying capacity of the existing hob disassembly mechanism are limited. It is necessary to develop a hob disassembly and assembly mechanism that is suitable for the harsh working environment of the shield machine, has a large bearing capacity, and has high replacement efficiency
