Crane hook

Abstract

The invention discloses a crane hook, which comprises a cross bar, a trapezoid embossment, an anti-skid buckle, and a support plate, two ends of the cross bar are both provided with a fixed block; a cross shape swing rod is connected to the middle of the cross bar through a hinge chain; the lower end of the vertical part of the swing rod is connected to a hook; a blind hole is arranged in each fixed block; the internal wall of the lower side of each blind hole is provided with a roller; two ends of the horizontal part of the swing rod are both provided with a groove; two ends of the horizontal part of the swing rod are connected to the bottoms of blind holes through springs respectively; the hook is provided with a hole, a push-pull type electromagnet is arranged in the hole, one end of the push-pull type electromagnet is provided with a push-pull rod, the other end of the push-pull type electromagnet is connected to a remote controller through a wire, and the other end of the push-pull rod is connected to the lower part of the anti-skid buckle. The crane hook has the advantages that the structure is simple; when a weight is hooked on the hook, the weight can be easily separated from the hook by slightly pressing the button of the remote controller to open the anti-skid buckle; the weight does not need to be moved by human, and great convenience is generated.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a crane hook. Background technique [0002] The gantry crane is a kind of deformation of the bridge crane, which is mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can walk directly on the ground track. The two ends of the main beam can have outrigger cantilever beams; the gantry crane has high site utilization rate and large operating range. , wide adaptability, and strong versatility, it is widely used in port freight yards. The gantry crane is a kind of gantry crane. The gantry crane is a kind of equipment commonly used in oil fields. It drives the running wheels to rotate through the driving device, so as to realize the movement of the whole gantry crane on the rail. The existing gantry crane mobile device is mainly driven by a cha...

AI Technical Summary

Problems solved by technology

The existing gantry crane mobile device is mainly driven by a chain, and the chain transmits the power of the driving device to each running wheel, driving the running wheel to rotate, thereby realizing the movement of the lifting object; but at the same time, this structure still has certain defects, the problem is that , when the load is just lifted, the load will shake in the horizontal direction, which reduces the safety factor in the operating environment
