Rapid replacement device for various tool bits of tunnel shield tunneling machine

Abstract

The invention discloses a rapid replacement device for various tool bits of a tunnel shield tunneling machine. The device comprises a shield tunneling machine body, a hanging beam, a pair of telescopic slings and a pair of auxiliary slings, the hanging beam is installed on the top side of the shield tunneling machine body, and the pair of telescopic slings are installed on the two sides of the end of the hanging beam; and the pair of auxiliary slings are installed at the end of the hanging beam and located on the two sides of the pair of telescopic slings, and a pair of rotary dismounting structures are arranged at the ends of the pair of auxiliary slings. The rapid replacement device for various tool bits of the tunnel shield tunneling machine has the beneficial effects that the structure is simple, the operation is convenient, two sets of hoisting equipment are arranged, old tool bits and new tool bits can be synchronously put down to a replacement station, the rotary dismounting structures are hoisted through the auxiliary slings, bolts for fixing the old tool bits are rotationally dismounted through the rotary dismounting structures, the dismounting process is greatly facilitated, dismounting personnel do not need to use too much strength, the operation is easier, and rapid, and the replacement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shield machine maintenance, in particular to a quick replacement device for various cutter heads of a tunnel shield machine. Background technique [0002] The shield machine is an important excavation equipment in a series of engineering constructions such as tunnels and pipelines. The shield machine plays an important role in breaking the cutter head during the work process. As the most vulnerable part to wear and tear, it needs to be replaced and repaired regularly. Repair, at the present stage, during the replacement process of the tunnel shield machine, most of the removed shield cutter bodies are transferred by hoisting equipment, but the position of the fixed shield cutter head still needs to be removed manually, so the replacement of the shield cutter head is very important. Workers at this stage are very tired. In view of this, this case has been produced after in-depth research on the above-menti...

[0002] The shield machine is an important excavation equipment in a series of engineering constructions such as tunnels and pipelines. The shield machine plays an important role in breaking the cutter head during the work process. As the most vulnerable part to wear and tear, it needs to be replaced and repaired regularly. Repair, at the present stage, during the replacement process of the tunnel shield machine, most of the dismantled shield cutter bodies are transferred by hoisting equipment, but the position of the fixed shield cutter head still needs to be removed manually, so replacing the shield cutter head is very important. Workers at this stage are very tired. In view of this, in-depth research on the above-mentioned issues led to this case.
