Abstract

The invention provides a cutter cylinder blocking resistance device which comprises a cutter cylinder. A washing ring groove located in the side part of the cutter cylinder is formed in the front endof the cutter cylinder, the part, located at the front end of the washing ring groove, of the cutter cylinder is lower than the part, located at the rear end of the washing ring groove, of the cuttercylinder, and a new washing channel extends to the position of the washing ring groove. The cutter cylinder blocking resistance device has the advantages that (1) targeted washing to the cutter cylinder can be achieved, and blocking and scratching of the cutter cylinder are effectively prevented; and (2) abnormal damage of the cutter cylinder can be reduced, and the cutter changing efficiency andcutter changing safety are improved.

Description

technical field [0001] The invention relates to tunnel boring equipment, in particular to a cutter barrel anti-jamming device. Background technique [0002] In the last ten or twenty years, shield tunnels are moving towards the direction of large diameter and large buried depth. Large-diameter mud-water balance shield technology has been applied more and more in engineering, but it still faces many difficulties when tunneling through ultra-high water pressure and complex strata. As the core component of the shield machine, the cutterhead tool is directly responsible for the excavation of the rock formation, and the underground rock formation has uneven hardness, boulders, boulders, caves, high-strength rocks and even pile foundations, etc., and the tools are worn, abnormally damaged and loosened. The probability is very high. For a cutter head with a diameter of about 15m in a composite stratum, it may be necessary to check and replace the cutter more than 50 times for 1 km...
