Automatic segmental box girder bottom die steel plate hoisting system

Abstract

The invention provides an automatic segmental box girder bottom die steel plate hoisting system. The system comprises a bottom die steel plate, a hoisting connecting base, a first puller bolt, a silica gel ring, a first telescopic rod, a second telescopic rod, a telescopic measuring rod structure, a clamping locking base structure, a rotatable protection base structure, a slidable hoisting base structure, a sliding pipe, an auxiliary base, an inserting rod, an auxiliary rope and an auxiliary hoisting ring. The first puller bolt penetrates through the middle of the left side and the right sideof the upper end of the hoisting connecting base correspondingly in threaded connection. The silica gel ring is in bolted connection with the left side and the right side of the hoisting connecting base respectively. Through the arrangement of a first connecting base, a fixing pipe, a third telescopic rod, a corresponding rod, the first telescopic rod and the second telescopic rod, it is facilitated that corresponding rods correspond to the two ends of the bottom die steel plate in the using process, then scale marks carved at the upper end of the third telescopic rod are observed, and the bottom die steel plate is prevented from inclining in the hoisting process.

Description

technical field [0001] The invention belongs to the technical field of steel plate hoisting equipment, in particular to an automatic section box girder bottom form steel plate hoisting system. Background technique [0002] The steel plate is a flat-shaped steel material that is poured with molten steel and pressed after cooling. After the steel plate is produced, it needs to be transported to other locations for additional processing. Since the steel plate is a wide and thin workpiece, manual processing is required. It will be more laborious to move it, and it may scratch people's hands. Now when the steel plate is hoisted and moved, the steel wire rope is used to bind the steel plate, and then the steel plate is hoisted on the steel wire rope with a hook hook. To facilitate hoisting, people have designed hoisting equipment. [0003] However, the existing hoisting equipment still exists in the process of use, which is easy to hang and affect the hoisting work. Making adjus...
