Casting and retreating device for press plate

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 pressplate, 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 press plate ejector. Background technique [0002] The protection pressure plate is a component that is used in a large number and often needs to be operated in the substation. It often needs to be put in or out according to the state of the main equipment. The so-called protection pressure plate is put into use. The operation of tightening the upper nut and the lower nut. The so-called withdrawal of the protection pressure plate refers to the operation of first loosening the upper nut and 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hand, which has the following disadvantages: because a large number of protection pressure plates need to be put in or withdrawn for each operation, it is time-consuming and laborious; the force used by the operator is different, and the protection pressure plate needs to be The phenomenon that it...
