A wear repair system for the sealing position of the drive shell of the shield machine

Abstract

The invention provides a sealing position abrasion repairing system for a shield machine driving shell. The sealing position abrasion repairing system comprises a fixed disc, a rotary disc, a rotating shaft, a driving device, a detecting device, a welding repairing device, a polishing device, a first conveying device, a second conveying device and a control device. The detecting device is used for detecting the sealing position abrasion condition of a shield machine driving shell in a blanking area and conveying a detection signal to the control device; the welding repairing device is used for conducting welding repairing on the sealing position of the shield machine driving shell in the blanking area; the polishing device is used for polishing the sealing position, obtained after welding repairing, of the shield machine driving shell in the blanking area; the first conveying device is used for conveying the to-be-detected shield machine driving shell into the blanking area of the rotary disc; the second conveying device is used for conveying out the repaired shield machine shell; and the control device is connected with the detecting device, the driving device, a movable door, the welding repairing device and the polishing device. By means of the sealing position abrasion repairing system, the welding repairing technology is used for repairing a workpiece, and high-precision repairing of the workpiece is achieved.

Description

technical field [0001] The invention relates to the technical field of component repair, in particular to a wear repair system for the sealing position of the drive shell of a shield machine. Background technique [0002] In industrial production, during the operation of various mechanical equipment, due to poor maintenance or other reasons, various forms of damage will occur, such as wear, strain, breakage, cracking, corrosion, etc., resulting in reduced equipment accuracy and performance. Affect product quality and must be repaired. If it is inconvenient to repair, the parts have to be replaced, or the machine is scrapped, which brings great losses to the production and operation of the enterprise. The shield machine has become the main construction equipment in the construction of urban rail transit. The drive shell of the shield machine is outside the main drive of the shield machine. On the one hand, it plays a supporting role, and on the other hand, it prevents impuri...

AI Technical Summary

Problems solved by technology

When the drive shell of the shield machine is in use, the sealing position of the drive shell is prone to shutdown due to severe wear and tear. At present, the method of inserting the sleeve is selected for repair. The worn part is ground to the deepest wear, and a steel sleeve is made according to the missing size, and it is installed together. However, there are deficiencies in this scheme: destroying the original structure and making up for it with inserts will reduce the structural strength and bearing capacity of the part
