Special simple fixing device for crane and application method thereof

Abstract

The invention relates to a special simple fixing device for a crane. The device comprises a first telescopic rod. The first telescopic rod is connected to a fixed part, the fixed part is connected toan angle adjustor, the other end of the fixed part is connected to a hydraulic oil cylinder, two sides of the hydraulic oil cylinder are fixed through supporting rods, the other ends of the supportingrods are fixed to the first telescopic rod, the hydraulic oil cylinder is connected to a second telescopic rod, a reel device is connected to the top of the second telescopic rod through a reinforcing plate, the reel device comprises a reel, the reel is fixed in a protecting hood through a supporting rack, limiting blocks are arranged at two ends of the reel, a speed stabilizer is arranged on thelimiting blocks, the limiting blocks are connected to a baffle plate, the baffle plate is connected to a pendant chain, the bottom of the pendant chain is connected to a lifting hook, the lifting hook comprises a hook body, the radian of the hook body is 150 degrees, a first round ring is welded to the hook body, the first round ring is vertically connected to a second round ring, and the tops ofthe first round ring and the second round ring are connected to a connecting part. The lifting hook is large in designed supporting capacity, high in anti-pressure ability and uniform in force distribution, the service life is prolonged, the stability and safety performance are improved, and the precision and work efficiency are improved.

Description

technical field [0001] The invention specifically relates to a special simple fixing device for a hoist and a using method thereof. Background technique [0002] The hoist is a common piece of equipment in modern life. Its fixing device is particularly important. It not only fixes the object, but also poses a great challenge to its support. The commonly used fixing device has a speed at both ends during the winding process of the hoisting chain. Inconsistencies, the design of the hook also has certain irrationality, prompting it to have a great potential safety hazard, while reducing work efficiency. Contents of the invention [0003] The object of the present invention is a special simple fixing device for a hoist and its use method, so as to solve the existing technical problems. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a special simple fixing device for a hoist, including a first telescopic rod, th...
