A turnover plug device applied to a safe and labor-saving cover plate comprises a plug and a plug library, the plug comprises a tongue and a clamping plate, the clamping plate is U-shaped, a U-shaped clamping groove is formed between an upper plate and a lower plate of the clamping plate, the U-shaped closed end of the clamping plate is fixedly connected with a mounting plate, and the tongue is hinged to the open end of the upper plate through a pin shaft; the insertion library comprises an insertion library plate, a shaft and a baffle plate, the baffle plate with the upper plane lower than the upper plane of the insertion library plate is welded at the opening of the front side surface of the insertion library plate, the shaft is welded on the inner wall of the upper part of the insertion library plate, and a slope-shaped guide plate in the same direction as the shaft is arranged in the lower part of the insertion library plate. The device is simple in structure and easy to produce and machine, the production cost is reduced, the work amount and labor investment are reduced, and good social and economic benefits are achieved.
Description
technical field [0001] The invention relates to a plug, in particular to a flipping plug device installed on a cover plate of a slot opening of a dam crest gate and applied to a safe and labor-saving cover plate. Background technique [0002] In the use of various safety and labor-saving cover plates for medium and large hanging objects, when the cover plate is opened, the gate cannot be lifted out due to the insufficient lifting height of the door operator, so it is often necessary to remove or lay down the guardrail on one side , to ensure that the gate can be lifted out smoothly. In order to place the safety guardrail, the plug under each safety guardrail needs to be made into a flip plug. The conventional flip plug is directly cut from a steel plate with a thickness of 40mm, and is processed by a planer, milling machine, drilling machine and other machine tools, and finally formed. Due to structural deficiencies, this flip plug has a large volume and heavy weight, and i...
