Abstract

The invention provides a friction type overload automatic disengaging sling. The danger that the heavy object falls after being hoisted is avoided. According to the solved technical scheme, the friction type overload automatic disengaging sling comprises a supporting frame, and a clamping device is arranged at the upper portion in the supporting frame and is composed of two clamping blocks. Each clamping block comprises an arc block, wherein the outer circle of the arc block is connected with a horizontal plate, a first connecting rod and a first pin shaft are arranged below the horizontal plate, the first connecting rod is arranged on the first pin shaft in a sleeving manner through a sliding groove, a baffle is arranged on the outer side of the first connecting rod, a strong spring is connected between the first connecting rod and the baffle, the upper end of the first connecting rod is hinged to the horizontal plate, and a limiting step is arranged in the supporting frame. A U-shaped frame is arranged under the clamping device and comprises a left vertical plate and a right vertical plate, a tension spring is connected between the inner side walls of the two baffles, and the friction force to the U-shaped frame from the left baffle and the right baffle under the action of the tension spring is larger than the gravity of the U-shaped frame, and adjusting screws are fixed to the left side and the right side of the supporting frame correspondingly. The friction type overload automatic disengaging sling is ingenious in concept and safe in usage.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a friction type overload automatic shedding sling. Background technique [0002] During the hoisting process of the crane, the thickness of the wire rope is very important, which is directly related to the safety of the hoisted object and the operator. During the hoisting process of the crane, in most cases, the hoisting is to hang the heavy object through the hook under the crane. Wire rope for lifting. [0003] Due to the fact that there are many thicknesses and specifications of steel wire ropes in each workshop, most operators choose steel wire ropes according to the rough estimation of the weight of the heavy objects when lifting, which may lead to inaccurate estimates when lifting. When the object is too heavy, the weight of the heavy object is greater than the lifting capacity of the steel wire rope. At this time, when the steel wire rope is used for hoisting, it is easy...
