I-shaped lifting equipment for box balance lifting

Abstract

The invention discloses an I-shaped hoisting device used for the balanced lifting of a box body. The I-shaped hoisting device mainly comprises a main beam, two support beams, hooking assemblies and a hoisting beam, wherein the middle parts of the two support beams are installed on the two ends of the main beam, the hooking assemblies are installed at four end parts of the two support beams and are correspondingly matched with hosted box body hangers, and the hoisting beam is fixedly arranged in the middle of the main beam. Two hooking holes are designed between the hoisting beam and the main beam, one of the two support beams installed at the two end parts of the main beam is fixed, and the other one support beam is movable, the movable support beam is installed on the end part of the main beam in rotating manner relative to a pin shaft assembly fixed on the main beam. Compared with the I-shaped hoisting device in the prior art, the I-shaped hoisting device disclosed by the invention has the advantages that torsion and bending moment in the horizontal plane direction, which are applied on the support beams and the main beam and caused by the uneven loaded article distribution can be fundamentally eliminated, the enough anti-twisting strength of the hoisting device can be ensured, and the volume and the weight of the hoisting device can be lowered greatly.

Description

technical field [0001] The invention relates to a box body lifting equipment, more specifically, relates to an I-shaped lifting equipment used for balanced lifting of a box body. Background technique [0002] During the hoisting process of the box loaded with loads, when the loads in the box have special requirements, such as maintaining balance, or not deforming, bruising, etc., it is necessary to use the balance beam lifting equipment for hoisting. Balance beam lifting equipment is mainly composed of rigid balance beam and flexible hook connection components (sling, shackle and hook, etc.). It avoids loads being subjected to compound forces and moments during the lifting process, and also has the advantages of shortening the length of the sling, lowering the lifting height, and shortening the time for loading and unloading heavy objects. [0003] In the prior art balance beam lifting equipment, the balance beam is mostly made of I-shaped steel and channel steel. The desig...

Problems solved by technology

[0006] Aiming at the deficiencies in the box balance lifting equipment in the prior art, the purpose of the present invention is to provide a new structure of I-shaped lifting equipment for box balance lifting to solve the problem of the I-shaped lifting equipment in the prior art. There is a problem that when the distribution of the loads in the box is uneven, the supporting beam and the main beam bear the torque and the bending moment in the horizontal plane direction, which leads to the problem that the whole lifting equipment is bulky and the weight is greatly increased.
