Electric power system draining pump lifting auxiliary device

Abstract

The invention discloses an electric power system draining pump lifting auxiliary device which comprises idler wheels arranged on a base. A rotary shaft is arranged above the base in a rotary mode through a support, rollers are fixedly and coaxially arranged on the rotary shaft, traction ropes used for connecting draining pumps winds the rollers, a through hole is formed in the base, a baffle is arranged on the base, a pump box used for containing the draining pumps is arranged in the middle of the baffle, the pump box is clamped in the through hole, a rocking handle is fixedly arranged at the end portion of the rotary shaft, a positioning disc is fixedly and coaxially arranged on the rotary shaft, and a locking piece is arranged between the positioning disc and the support. Supporting rods only capable of swinging at the bottom of the base are hinged to the two ends of the bottom of the base respectively, a limiting block matched with the end portion of the base in a supporting mode to support the idler wheels to leave the ground is fixedly arranged at the hinged end of each supporting rod, series installing holes aligned with one another are formed in the supporting rods, and series installing rods enabling the supporting rods to be fixedly installed below the supporting rods in a series mode are arranged in the series holes in an inserted mode. The electric power system draining pump lifting auxiliary device is reasonable in structure, stable in lifting, simple to operate, fast in transferring, beneficial to improving working efficiency and particularly suitable for being used during emergency rescuing and drainage, and saves time and effort.

Description

technical field [0001] The invention relates to a lifting auxiliary device for a drainage pump in a power system. Background technique [0002] The focus of the substation's flood control work is to ensure the safety of the substation during the flood season, and to meet the requirement that the substation and its production and living facilities will not be flooded when encountering heavy rain or flood exceeding the design standard. Special attention should be paid to substations with low terrain and substations with flooding experience. In the process of flood control, ensuring the normal and effective drainage work is one of the key points of substation flood control work. [0003] Since there is no special auxiliary equipment for lifting the drainage pump in the power system, at present, the method of manually lifting the drainage pump is used to enter and exit the drainage well, that is, the top of the drainage pump is tied with a rope, and the flood control personnel g...

AI Technical Summary

Problems solved by technology

While this method is simple and practical, it has brought many problems, such as seriously consuming the physical strength of the flood control personnel, taking up too many human resources and causing tension in the flood control personnel, improper force causing the drainage pump to swing and hit the well wall to damage the drainage pump, and because all It is a manual operation, so it is easy to be squeezed by the water pump or scratch the skin by the rope when lowering or raising the water pump

In addition, when transferring the drainage pump, at least two people are required to lift it, which is time-consuming and laborious, and reduces the drainage efficiency. This defect is more obvious during emergency flood control
