Multi-point lifting appliance

Abstract

The invention discloses a multi-point lifting appliance which comprises a main beam, auxiliary beams, trapezoidal blocks, thread grooves, screw rods, lifting hooks, a lifting seat and thread holes. The lifting seat is welded to the middle of the main beam, and a dovetail groove extending inwards is formed in the lower end face of the main beam. The trapezoidal blocks are fixedly connected to the middles of the upper end faces of the auxiliary beams, and the auxiliary beams are connected with the lower end face of the main beam through the trapezoidal blocks. The thread grooves are longitudinally formed in the trapezoidal blocks, and the screw rods penetrate through the upper end face of the main beam to be in threaded fit with the threaded grooves in the trapezoidal blocks and are fixed through nuts. Threaded parts are arranged on the upper portions of the lifting hooks, and through holes are formed in the left sides and the right sides of the auxiliary beams. The number of the lifting hooks is two, and the lifting hooks are connected to the two ends of the auxiliary beams through nuts. The thread holes are formed in the front end and the rear end of the main beam. The multi-point lifting appliance has the advantages of being novel in structure and high in efficiency.

Description

Technical field [0001] The present invention involves a multi -dot -type paddy, which is used in the field of lifting crane technology. Background technique [0002] With the rapid development of society, the crane is widely used, and the crane crane is an important part of the crane to make a hanging machine. With the different material shape, size, and weight, the structure of the crane crane is also different; the general lifting hanging suspension suspensionGe is composed of a ring that is set by the beams and the ends of the beams. Such a piano can only perform some simple lifting work. For some large -volume and light weight materials, it will be more troublesome to operate with such pingsons.Due to the characteristics of such materials, a patch can be used for multiple workpieces that can be carried out at one time. Invention content [0003] In order to solve the defects of existing technical solutions, the present invention has disclosed a multi -point piano, which has ...

Problems solved by technology

[0002] With the rapid development of society, cranes are widely used. Crane spreaders are an important part of hoisting with cranes. With different shapes, sizes and weights of materials, the structures of crane spreaders are also different; The lifting tools are composed of beams and lifting rings arranged at both ends of the beams. This kind of lifting equipment can only carry out some simple lifting work. For some materials with large volume and light weight, it will be more troublesome to use this type of lifting equipment. , due to the characteristics of this type of material, you can choose a spreader that can lift multiple workpieces at one time
