A telescopic spreader

Abstract

The invention discloses a telescopic hanger, which comprises a top box body. The top box body is provided with symmetrical inner cavities for placing steel cables. Between the inner cavities for placing steel cables, there is a middle box located in the top box body. The inner cavity, the lower end wall of the middle inner cavity is connected with a symmetrical penetrating inner cavity, the penetrating inner cavity is arranged vertically, the lower side of the top box is provided with a bottom box, and the two sides of the bottom box are A symmetrical side fixing block is fixed on the side end surface, and a box body is provided for sliding clamping in the bottom box body. The inside of the box body is a hollow structure, and a symmetrical transmission inner cavity is arranged in the box body. A number of unwinding devices are provided in the inner cavity and the middle inner cavity, and the unwinding device is provided with a penetrating inner cavity. The equipment can respectively make the bottom box body and the box body telescopically lift, and use the two-stage bottom box The body and the box body can use the matching hook and the hanging hook to hang articles respectively, and have good firmness.

Description

technical field [0001] The invention relates to the technical field of spreader equipment, in particular to a telescopic spreader. Background technique [0002] Existing slings often adopt a single lifting method, using a single sling to hoist objects, which depends to a large extent on the length of the suspension rope of the sling and the height of the sling. More problems, such as: Chinese patent publication number is CN209081241U, the name is self-adjusting length large steel cage hoisting auxiliary device and hoisting system, the announcement date is 20190709, when the sling is hoisted for objects on different height floors, only The efficient hoisting of objects on different floors can be achieved by using a single sling for multiple repeated hoisting, which increases the work intensity of personnel and equipment to a large extent, making the equipment inefficient when it is working, and because In actual work, many times of repeated work increases the aging times of ...

Problems solved by technology

[0002] Existing slings often adopt a single lifting method, using a single sling to hoist objects, which depends to a large extent on the length of the suspension rope of the sling and the height of the sling. More problems, such as: Chinese patent publication number is CN209081241U, the name is self-adjusting length large steel cage hoisting auxiliary device and hoisting system, the announcement date is 20190709, when the sling is hoisted for objects on different height floors, only The efficient hoisting of objects on different floors can be achieved by using a single sling for multiple repeated hoisting, which increases the work intensity of personnel and equipment to a large extent, making the equipment inefficient when it is working, and because In actual work, many times of repeated work increases the aging times of the steel ropes and spreaders, which increases the frequency of replacement of the internal structural parts of the equipment. If the steel ropes and spreaders are not replaced, it also causes a risk factor during the working process of the equipment. , which endangers the safety of people and property near the hoisting area
