Abstract

The invention discloses quick dismounting and mounting equipment for an expansion joint of a ball valve. The quick dismounting and mounting equipment comprises a vehicle frame (1), wherein moving wheels (2) are arranged at the bottom of the vehicle frame (1); supporting blocks (3) are correspondingly arranged at the front and rear ends of the upper part of the vehicle frame (1); a lifting air cylinder (4) is arranged between the two supporting blocks (3); a supporting frame (5) is arranged at the extending end of the lifting air cylinder (4); an arc-shaped plate (6) is arranged at the upper end of the supporting frame (5); a plurality of grooves are formed in the inner wall of the arc-shaped plate (6); magnets (7) are arranged in all the grooves; a bolt dismounting and mounting mechanism (8) is arranged at the left end of the vehicle frame (1); and an expansion joint fixing mechanism (9) is arranged at the right end of the vehicle frame (1). The quick dismounting and mounting equipmentdisclosed by the invention has the characteristics that the operation difficulty can be lowered, the labor intensity of workers can be reduced, and the dismounting efficiency can be improved.

Description

technical field [0001] The invention relates to a dismantling device for an expansion joint, in particular to a quick disassembly and assembly device for a ball valve expansion joint. Background technique [0002] When performing maintenance on the sealing performance of the ball valve, it is necessary to remove the expansion joint and move it to a maintenance site that does not hinder the removal of the working seal of the ball valve. Since the expansion joint and the ball valve are connected by multiple bolts, it is necessary to use a guide chain to fix the expansion joint during the dismantling operation, and then manually remove the bolts. Due to the large number of bolts, the labor intensity of the workers is relatively high. In the process of transporting the expansion joint, the track is first laid with square wood, and then the guide chain is hung on the two lifting points set above. The force is on the expansion joint, and then the expansion joint is laid on the squ...
