Document Type and Number:
WIPO Patent Application WO/2023/202088
Kind Code:
A1
Abstract:
A mud cake formation prevention steel plate for a shield cutter head, and a simulation test table and test method for characteristic testing thereof. The steel plate is installed on a shield cutter head, is snap-fitted to a rake face (1) of a cutting bit on a cutter head, is consistent with the rake face (1) of the cutting bit on the cutter head in shape, position and size, and is connected to the rake face (1) by means of a bolt; the steel plate is made of one of molybdenum-vanadium alloy and Q235/Q245, and the smoothness of the upper surface thereof is less than 0.1. Equivalently, a layer of tempered film beneficial to mud sliding is additionally arranged on the cutting bit, and the tempered film has a set of detection platform so as to be adjusted and replaced in real time under different working conditions. Information of a cutting face can be quickly obtained, and the problem in the prior art that mud cake formation on a shield cutter head affects the outflow of mud, and thus affects the overall working state is solved.
