Problems solved by technology

The repair of large shafts is more troublesome. After dismantling and transferring to the manufacturing factory for repair, the processing quality can be guaranteed to the greatest extent, but the resulting disassembly, transfer and installation work takes a long time and the cost is extremely high. Sometimes due to the constraints of objective factors not even enforceable
On-site repairs are traditionally done manually, the quality requirements are difficult to control, and the cost and construction period are long.
At the same time, the on-site conditions may be more complicated, and complete sets of equipment and special devices that can adapt to various on-site conditions are required.

Abstract

The invention discloses a repairing device for a shaft end of a large gear shaft; the repairing device comprises a bearing platform, a locking device and a transmission device, wherein the bearing platform comprises a chassis as well as wheels and hydraulic support legs, and the wheels and the hydraulic support legs are arranged below the chassis; the transmission device is arranged on the upper surface of the chassis; the locking device comprises a top frame, one end of the top frame is detachably and fixedly arranged on the bearing platform or detachably and fixedly arranged at the top of atransmission gear box of a transmission arranged on the chassis, and the other end of the top frame is detachably fixed on an action object; and the transmission device comprises a motor and a changespeed gear box which are arranged on the bearing platform as well as a processing element rotating shaft driven by the motor and the change speed gear box, and the processing element rotating shaft isprovided with a shaft end processing device. Without returning to the factory and transshipment, the repairing efficiency is improved, the repairing cycle is shortened and cost is reduced; and compared with manual repair, improvement of the repairing quality and quality consistency can be guaranteed to a certain extent.

Description

technical field [0001] The invention relates to the field of repairing large shaft parts. Background technique [0002] Large-scale shaft parts such as mining equipment, super-large equipment shafts, steam turbine and generator rotors, and marine crankshafts are getting larger and larger. Due to the influence of the use environment, shaft ends or gears are easily damaged. Whether it is to replace gears or shaft ends If it breaks down, it needs to be repaired. The repair of large shafts is more troublesome. After dismantling and transferring to the manufacturing factory for repair, the processing quality can be guaranteed to the greatest extent, but the resulting disassembly, transfer and installation work takes a long time and the cost is extremely high. Sometimes due to the constraints of objective factors Not even enforceable. On-site repairs are traditionally done manually, which makes it difficult to control the quality requirements, and the cost and construction perio...
