Problems solved by technology

However, it is difficult for the existing clamper to place the hob stably in the knife seat. After the clamper releases the hob, the hob is very easy to roll in the knife seat, resulting in confusion in the swing sequence of the hob, and there is a problem of misinstalling the hob. risk, relatively low reliability

Abstract

The invention discloses a tool changing device for replacing the hob of a shield machine. Two locking tool holders are respectively fixed on both sides of the hob. The clamper includes a clamping claw and a driving assembly, and the clamping claw is used for clamping the lock. The knife holder, the driving assembly is connected with the clamping claw, and the driving assembly drives each locking knife holder to expand in the knife storage groove, so that the locking knife holder and the knife storage groove are matched, so that the hob is stably locked by the locking knife holder In the knife storage slot, it prevents the hob from rolling freely, avoids installing wrong hobs, reduces the risk of misoperation, and improves reliability accordingly. Therefore, the reliability of the tool changer for changing the hob of the shield machine provided by the present invention is improved.

Description

technical field [0001] The invention relates to the technical field of shield machine tool change, in particular to a tool change device for replacing a shield machine hob. Background technique [0002] Shield machines are widely used in major engineering fields such as urban subways, highway tunnels, and water conservancy projects. The hobs installed on the cutter head are usually worn out and need to be replaced frequently. In view of the fact that the shield machine is usually constructed under harsh working conditions such as large burial depth and high water pressure, there are great safety hazards, and construction personnel need to use the tool changer to replace the hob regularly. [0003] However, the existing tool changing device includes a mechanical arm and a clamper, and the clamper is installed at the end of the mechanical arm so that the mechanical arm drives the clamper to clamp the hob. However, it is difficult for the existing clamper to place the hob stab...
