A knife seat device

Abstract

The invention discloses a cutter holder device, which comprises: a hob holder for supporting both ends of a hob cutter shaft, a pressing device arranged on the hob holder and used for locking the end of the hob cutter shaft , the pressing device includes a pressing piece for pressing the end of the hob cutter shaft, a fastener connected with the pressing piece and used to drive the pressing piece to move through its own circumferential rotation, and the pressing piece can be relatively The movement of the hob knife seat is limited. When the fastener is tightened, the pressing piece presses the end of the hob knife shaft. When the fastener is loosened, the pressing piece releases the pressure on the hob knife shaft. end pressure. By using the tool seat device provided by the invention, the robotization of the tool changing operation of the cutter head tool of the shield machine can be realized, and it can be widely used.

Description

technical field [0001] The invention relates to the technical field of shield machine engineering, and more specifically, relates to a tool seat device. Background technique [0002] The shield machine is a special construction machine for tunneling. It has the functions of excavating soil, transporting muck, and lining pipelines. It has been widely used in tunnel projects such as subways, railways, highways, coal mines, and water conservancy and hydropower. [0003] In the prior art, the tool change form of the cutter head of the shield machine is mainly manual tool change. However, the single tool change time is as long as more than ten days, and the tool change cost is tens of millions. Moreover, the tool change There is a great potential safety hazard in the process of personnel transfer. [0004] In a small number of tunnels with extremely simple geological conditions, the engineering application of using robots to change the cutter head of the shield machine has begun...

[0003] In the prior art, the tool change form of the cutter head of the shield machine is mainly manual tool change. However, the single tool change time is as long as more than ten days, and the tool change cost is tens of millions. Moreover, the tool change There is a great potential safety hazard in the process of personnel transfer

[0004] In a small number of tunnels with extremely simple geological conditions, the engineering application of using robots to change the cutter head of the shield machine has begun, mainly through the fixed connection of the lug and the slot on the tool holder for force transmission. , the tool holder usually cannot withstand large load impact, and its structure is complex and the manufacturing cost is high. Therefore, it cannot be widely used in other geological conditions, which leads to the stagnation of the progress of the robotization of the tool change operation of the shield machine cutter head tool Not moving forward
