Abstract

The invention relates to the field of pipe jacking machines, in particular to an open type pipe jacking machine slotting tool baffle control method, which comprises a shield body, slotting tools, baffles, slotting tool oil cylinders, a slag car and a slag car weighing system, the shield body is provided with a controller, the upper half part of the shield body is respectively provided with at least 10 groups of slotting tools and 8 groups of baffles, the slotting tool comprises a slotting tool main body and a slotting tool cutter, the slotting tool cutter is welded to the slotting tool main body, the actions of the slotting tool and the baffle and the propelling action of a tank body of the shield body are achieved, and a closed-loop feedback automatic control process is formed; the actions of the slotting tool and the baffle are combined to form an organic whole, and interlocking control is carried out; by designing a slotting tool protection system and a baffle protection system, mechanical structures and hydraulic systems of the slotting tool and the baffle can be protected when the slotting tool and the baffle act and are stuck.

Description

technical field [0001] The invention relates to the field of pipe jacking machines, in particular to a method for controlling a slotting knife baffle of an open pipe jacking machine. Background technique [0002] The open pipe jacking machine is a combination of the pipe jacking method and the underground excavation method. The main drive and cutter head are not configured in the front shield of the main engine system, but rely on equipment such as mechanical buckets or cantilever roadheaders in the front shield. The stratum can be excavated flexibly under the support of the body. [0003] The actions of the plunger and the baffle are controlled by the oil cylinder. The current scheme still adopts manual control alone. Each action cylinder is set with a manual reversing valve, and the excavation situation is judged manually, and then the plunger and the block are manually controlled. action of the board. The control method is relatively backward, unable to interlock with o...
