Problems solved by technology

The traditional operation method is to directly tighten or loosen the upper and lower nuts by hand, which has the following disadvantages: because a large number of protective pressure plates need to be put in or out for each operation, it is time-consuming and laborious; The phenomenon of looseness when withdrawing; when the protective pressure plate is put in, the upper and lower nuts must be tightened, and it is easy to miss the nut and cause poor contact

Abstract

The invention relates to a casting and retreating device for a press plate, comprising a shell in which a transmission gear, an upper gear and a lower gear are arranged, wherein the upper gear and the lower gear are engaged with the transmission gear, the outer end of a shaft of the transmission gear is provided with a turning handle, the inner ends of shafts of the upper gear and the lower gear are respectively provided with an upper sleeve and a lower sleeve, the distance between the upper sleeve and the lower sleeve is equal to the distance between an upper nut and a lower nut of the press plate, the upper sleeve and the lower sleeve are provided with wedge-shaped holes which are large at the outside and small at the inside, and convex teeth extending along the depth direction of each hole are arranged on the inner wall of each hole. The casting and retreating device for protecting the press plate is convenient to carry and flexible and reliable to operate when in use.

Description

technical field [0001] The invention relates to a pressing plate throwing and retreating device. Background technique [0002] The protective pressure plate is a component used in a large number of substations and often needs to be operated. It often needs to be put in or out according to the state of the main equipment. The operation of tightening the upper nut and the lower nut. The withdrawal of the so-called protection pressure plate refers to the operation of first loosening the upper nut and the lower nut, and then opening the connecting piece. The traditional operation method is to directly tighten or loosen the upper and lower nuts by hand, which has the following disadvantages: because a large number of protective pressure plates need to be put in or out for each operation, it is time-consuming and laborious; The phenomenon of looseness when withdrawing; when the protective pressure plate is put in, the upper and lower nuts must be tightened, and it is easy to mis...
