Abstract

The invention discloses a tearing knife replacing manipulator which solves the problems that potential safety hazards exist and labor time is consumed when tearing knives are replaced in the prior art. The tearing knife replacing manipulator comprises a fixed base, a rotary arm and a manipulator palm which are sequentially connected; the fixed base is arranged on a horizontal moving track inside ashield tunneling machine chamber in a sliding mode; the rotary arm comprises three mechanical arms which are sequentially connected and can rotate relatively; the free end of the rotary arm is connected with the manipulator palm which can rotate around the axis of the manipulator palm; a hexagon hole matched with a fixing nut of a tearing knife is formed in the axial direction of the manipulatorpalm; and the outer end portion of the hexagon hole is provided with a telescopic clamping jaw which can stretch and retract in the radial direction of the hexagon hole. The invention further discloses a control method of the tearing knife replacing manipulator. The tearing knife replacing manipulator is simple in structure and convenient to produce and manufacture, the production cost is reduced,the design structure is ingenious, the tearing knife can be rapidly and remotely controlled and replaced, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tearing knife replacement, in particular to a tearing knife replacement manipulator and a control method thereof. Background technique [0002] In the field of underground engineering, the application of shield tunneling method is more and more extensive. With the maturity of shield technology, the shield tunnel excavation area presents a trend of high buried depth and high water pressure, so the improvement of construction efficiency is an important research topic. In the process of underground construction of the shield machine, the tearing knife is the main excavation functional part. Once the tearing knife is damaged, the tunnel excavation cannot be continued and must be shut down for maintenance. The structure of the tearing knife in the prior art is complex. , the replacement is very difficult, so the replacement time of the existing tearing knife seriously affects the construction efficiency of th...
