Description

Technical Field

[0001] The utility model is applied to the disassembly and assembly of water pumps and motors during the maintenance of water supply equipment. It is a mechanical lifting fixture and relates to the field of fixtures. Background Technique

[0002] During the hoisting process of deep well pumps and motors, considering the lengths of pipelines and cables, usually for each hoisted pipeline (each 3 meters, with a net weight of about 0.4 tons per operation cycle and the maximum output of the crane reaching about 20 tons), such repeated operations are carried out until the hoisting is completed. Since the crane can only provide hoisting tools such as U-shaped rings and steel wires, and only the flange of the pipeline can bear force, while the U-shaped ring and steel wire cannot fix the pipeline flange well. During the hoisting operation, the two most critical links are load-bearing and fixing against detachment. Usually, these two links are related. In the current hoisting operation of deep well pumps, generally, a disc-shaped fixture is first used to support the flange on the wellhead, then bolts are used to fix the flange on two semi-circular lifting tools, and finally the hoisting is completed through the semi-circular lifting tools. In this process, bolts are used for fixing and the semi-circular lifting tools bear the load, resulting in low hoisting efficiency and cumbersome procedures, which become the difficulties in the hoisting operation of deep well pumps and motors.

By moving the position of the rectangular structure, the size of the flange installation groove is matched with the flange of the deep well pump pipe, and the fastener is used to fasten the triangle structure and the rectangular structure during hoisting.

[0005] Preferably, a groove is arranged under the bottom edge of the triangle structure, and a protrusion is arranged above the rectangular structure. The protrusion is placed in the groove to form a sliding connection method; according to the structural dimensions of different well pump pipe flanges, through holes are arranged on the protrusion and the bottom edge of the triangle structure, and after moving in place, fastening is achieved by the fastener passing through the through holes.
