Abstract

The invention discloses a clamp for repairing a shield tunneling machine sealing runway through laser cladding and a using method thereof. The clamp comprises a chassis, hydraulic oil cylinders, pushing pieces and an adjusting mechanism, wherein three flange guide rails forming 120-degree included angles are arranged at the position, close to the outer circle, of the front face of the chassis; anda slide groove is formed in the position close to the circle center above each flange guide rail; a hydraulic oil cylinder and a pushing piece are arranged at the bottom of each slide groove. In theclamp repairing shield tunneling machine sealing runway through laser cladding, a vertical clamping mode is adopted, so that the working space is reduced, the cladding head is vertically opposite to apart to be repaired, a light spot can keep constant in the shape and size, and the improvement of the energy utilization rate and the repairing efficiency are facilitated; a pushing device is drivenby the hydraulic oil cylinders, so that the rotation stability is ensured; the adjusting mechanism is adopted to adjust a contact position of each pushing piece and the inner ring of the sealing runway, elastic protruding materials are adopted at the contact position of each pushing piece to increase static friction force, and synchronous rotation of a pushing rod and a workpiece is achieved.

Description

technical field [0001] The invention relates to a jig for laser cladding and repairing a sealed runway of a shield machine and a use method thereof, and relates to the technical field of remanufacturing and repairing. Background technique [0002] When the shield machine is excavating in the tunnel, the main bearing seal runway and the lip seal ring rotate and rub against each other. Due to the harsh construction conditions, it is inevitable that hard particles will infiltrate the main bearing sealing system, and wear grooves often appear on the grinding surface. When the groove When it reaches a certain depth, the main bearing seal runway and the lip seal ring cannot be in close contact, the main bearing seal will fail, and the entire shield machine will not be able to continue to serve. The cost of replacing the sealed runway of the shield machine is high. In view of its single damage form, remanufacturing and repairing is one of the important ways to maintain its value an...
