Prefabricated beam hanger based on bridge

Abstract

The invention discloses a prefabricated beam hanger based on a bridge. The hanger comprises an outer frame, the left side of the outer frame is fixedly connected with a first motor, one end of an output shaft of the first motor penetrates through the outer frame and extends into the outer frame, and a screw rod is fixedly connected to the end, located in the outer frame, of the output shaft of the first motor; the two sides of the surface of the screw rod are both in threaded connection with a movable block, the bottom of each movable block is fixedly connected with a vertical rod, and the bottom of each vertical rod penetrates through the outer frame and extends to the outside of the outer frame. The invention relates to the technical field of prefabricated beam hangers. The prefabricated beam hanger based on the bridge achieves the purpose of adjusting the distance so that the hanger can conveniently adapt to prefabricated beams of different types and can be conveniently used by people, the application range of the hanger is enlarged, and the hanger can rotate; the direction of each prefabricated beam is convenient to adjust, the prefabricated beams are convenient to install, the burden of workers is reduced, the prefabricated beams are convenient to move, the prefabricated beams can be moved to proper positions, and the practicability of the hanger is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated beam spreaders, in particular to a bridge-based prefabricated beam spreader. Background technique [0002] The English name of the spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used spreaders for lifting the finished items are hooks and slings. Others include rings, lifting suction cups, clamps and forks. Widely used in the hoisting and hoisting industry. Special slings such as hooks, wire ropes, and chains are commonly used in the spreader. Lifting suction cups, clamps and forks can be used as special spreaders on the crane for a long time, and can also be used as The replaceable auxiliary spreader is hung on the hook for temporary use. It is often used in multi-cargo warehouses and yards to improve work efficiency. The spreader for grabbing bulk materials is generally a grab bucket with jaws that can be opened and closed. The electrom...
