Turning-over method, structure and device for large-scale equipment

Abstract

The invention discloses a turning-over method, a turning-over structure and a turning-over device for large-scale equipment. The turning-over structure comprises rotating shafts and the turning-over device, wherein the rotating shafts are arranged on the two sides of the large-scale equipment; the turning-over device is arranged at the bottom of a shield body and is used for supporting the rotating shafts; the turning-over device comprises two supports which are positioned below the rotating shafts on the two sides of the large-scale equipment; U-shaped bases are arranged on the tops of the two supports; the two U-shaped bases are coaxial, are matched with the rotating shafts on the two sides of the large-scale equipment and are used for supporting the two rotating shafts; and the rotating shafts can rotate on the two supports. The large-scale equipment is turned over by the following steps of: placing the rotating shafts on the two sides of the large-scale equipment on the U-shaped bases on the two sides of the turning-over device; lifting one side of the large-scale equipment slightly by using a crane; putting down the large-scale equipment after taking a supporting rod out of the bottom; lifting the other side of the large-scale equipment by using the crane; putting down the large-scale equipment again after taking the supporting rod out, so that the bottom of the equipment is hung in the air, is placed on the U-shaped bases on the two sides of the turning-over device through the rotating shafts on the two sides of the large-scale equipment, and is supported by the two supports of the turning-over device; and rotating the large-scale equipment around the rotating shafts so as to turn over the large-scale equipment. The large-scale equipment is turned over conveniently and quickly.

Description

technical field [0001] The invention relates to a method for turning over large equipment, and a structure and device for turning over large equipment. Background technique [0002] Due to the needs of assembly or work, large-scale equipment sometimes needs to be turned over. However, due to its huge size and weight, turning over is very difficult. Usually, a large crane is required for operation, which not only requires a large operating space, but also takes a long time, and there is a certain degree of danger in the operation. For example, as a shield machine used in the construction of underground tunnels as a large-scale equipment, during the assembly process, many parts (such as: the rings of the shield body, hinged cylinders, propulsion cylinders, etc.) need to be installed in the vertical state of the shield body. For assembly, the shield body is placed in a vertical state, and the bottom is supported by supporting rods. After these devices are installed, the shiel...
