Pin unlocking device used for separating reinforcing mesh cage from steel chisels

Abstract

The invention discloses a pin unlocking device used for separating a reinforcing mesh cage from steel chisels, and belongs to the field of aerated concrete product production-manufacturing. The pin unlocking device comprises a supporting frame, a lifting frame, a horizontal supporting frame, an unlocking support and an unlocking pin support. The lifting frame can be driven by first driving devices to rise and fall on the supporting frame. The horizontal supporting frame is slidably connected to the lifting frame. The unlocking support is connected to the horizontal supporting frame. The sliding direction of the unlocking support relative to the horizontal supporting frame is perpendicular to the sliding direction of the horizontal supporting frame relative to the lifting frame in the horizontal direction. The unlocking support is provided with a plurality of positioning pins used for being connected with positioning holes in the reinforcing mesh cage in an inserted mode. The unlocking pin support is slidably connected to the unlocking support and is driven to slide by a second driving device, so that that all unlocking pins on the unlocking pin support apply acting force to the corresponding steel chisels, so as to enable the steel chisels to be separated from the reinforcing mesh cage. According to the pin unlocking device, the stability and precision of unlocking between the steel chisels and the reinforcing mesh cage can be improved, and the situation that the quality of aerated concrete products is lowered due to an unlocking operation is avoided.

Description

technical field [0001] The invention belongs to the field of production and manufacture of air-entrained concrete products, and in particular relates to a needle unlocking device for separating steel mesh cages and steel drills for the production of air-entrained concrete slabs. Background technique [0002] In order to ensure the strength of the aerated concrete slab and to facilitate transportation and installation, it is necessary to bury a reinforced mesh cage during its production and manufacturing process. The steel drill of the steel mesh cage hanger carries the steel mesh cage and puts it into the fermented liquid concrete in the mold. After the fermentation time is sufficient, the steel drill and the steel mesh cage need to be separated so that the steel mesh cage hanger can rotate again to participate in the subsequent green body The production, the process of breaking away is unlocking. During the process of unlocking the steel braze and steel mesh cage, the body...

Problems solved by technology

The unlocking device on domestic cranes drives a push rod to move through the connecting rod structure, and pushes the top of the entire row of steel drills to make the steel drills rotate and separate from the steel mesh cage. When the entire steel mesh cage hanger is lifted, the steel drills are released from the steel mesh. cage, due to the large number of steel drills in each row and the long length of the push rod, the push rod will be deformed when pushing the steel drill, and the stability is poor. body damage
