Problems solved by technology

[0002] In the prior art, when a crane lifts cylindrical materials, an electromagnet spreader is used: for example, when lifting a steel cage, due to the existence of an air gap, the suction force may not be enough to lift the material; the use of a self-weight clamp spreader: the size is correct 1. There are strict requirements on weight, such as a lot of materials in the factory building, and there are many types of spreaders, which will increase the cost; using hooks to assist wire ropes or lifting belts for lifting: waste of labor costs and low degree of automation

Abstract

The invention discloses a lifting appliance for specially lifting cylindrical materials and a crane thereof. The lifting appliance comprises a lifting appliance beam, a driving device and a pluralityof lifting appliance components, wherein the driving device is arranged on the lifting appliance beam, and the lifting appliance component is arranged on the driving device; the driving device comprises two parallel cross beams, two cross beam support parts which are perpendicular to the cross beams and a driving mechanism which is used for driving the cross beams to move; and the driving mechanism adopts a slider-crank mechanism. According to the lifting appliance, an oil cylinder or a motor reducing gear is used as motive power; the slider-crank mechanism is used for driving the lifting appliance to open and close; a sliding block in a crank block is designed in the form of a beam as required, and a plurality of lifting appliance bodies can be arranged on the beam, so that materials withvarious lengths can be lifted; and clamping blocks on the lifting appliance bodies are designed in the form of an arc, and the arc is designed according to the maximum diameter of the lifted materials and is installed on a fixture, so that all materials of which the diameter is less than the diameter of the arc of the clamping blocks can be lifted.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a hoisting tool and a crane specially used for hoisting cylindrical materials. Background technique [0002] In the prior art, when a crane lifts cylindrical materials, an electromagnet spreader is used: for example, when lifting a steel cage, due to the existence of an air gap, the suction force may not be enough to lift the material; the use of a self-weight clamp spreader: the size is correct 1. There are strict requirements on weight. For example, there are many materials in the factory building, and there are many types of spreaders, which will increase the cost; using hooks to assist wire ropes or lifting belts for lifting: waste of labor costs and low degree of automation. Contents of the invention [0003] In order to overcome the defects of the prior art, the invention provides a hoisting device and a crane specially used for hoisting cylindrical materials. [0004...
