Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] attached figure 1 It is the overall schematic diagram of the spreader. The spreader is composed of an earring bolt 1, a support sleeve 2, a ferrule 8, a pull rod 6, and a pair of claws 11. Since the pull rod 6 is inside the support sleeve 2 by figure 1 cannot be seen in.

[0018] Below in conjunction with other drawings, the components of the spreader will be described one by one.

[0019] attached figure 2 is the perspective view of the support sleeve, by figure 2 It can be seen that the support sleeve 2 is a cylindrical tube, which is formed by figure 2 It can also be seen that the inner wall of the tube above the cylindrical tube of the support sleeve 2 is provided with an internal pipe thread 3 on the upper part of the support sleeve.

[0020] attached image 3 It is a perspective view of the support sleeve. From this figure, it can ...

Abstract

The invention relates to a hanger. For solving the technical problems of steel deformation, scratch and unhooking when the conventional round steel is hoisted, the invention adopts the technical scheme that: the hanger for hoisting the round steel comprises a lug ring connected with a hook; the hanger also comprises a supporting sleeve, a clamping sleeve, a pull rod and a pair of clamping jaws; and after combination, the clamping sleeve can control closing of the clamping jaws, so that the effect of grabbing the round steel by the clamping jaws is achieved. The hanger has the advantages of simplicity in structure, low manufacturing cost, convenience for operation and hoisting reliability.

Description

technical field [0001] The invention relates to a sling, in particular to a sling used for hoisting round steel. Background technique [0002] The factory needs to use round steel for processing when producing shaft products. At present, the lifting of round steel is mainly carried out in two ways. One is to directly block the round steel with the hook for lifting and shifting, and the other is to use the cooperation of the hook and the wire rope. Bundle round steel for lifting and shifting. Both methods will cause deformation and surface scratches of the round steel, especially for the hoisting of the processed large shaft, and the above-mentioned situation is not allowed, and the above-mentioned hoisting methods are likely to cause the round steel to decouple, which brings great safety hazards . Contents of the invention [0003] The object of the present invention is to provide a spreader for hoisting round steel, so as to overcome the technical problems of deform...
