Lifting device for thin-wall tower equipment

Abstract

The invention discloses a lifting device for thin-wall tower equipment. The lifting device comprises a lifting appliance and a rope tool, wherein the lifting appliance comprises a hook; the rope toolcomprises a plurality of lifting lugs which are fixedly arranged on thin-wall tower equipment and a balance beam with a plurality of lifting parts; the lifting lugs are linked with the balance beam through first steel wire ropes which pass through the lifting parts; the balance beam is arranged on the hook in a lifting manner through a second steel wire rope; the balance beam comprises a transverse beam plate and a vertical beam plate; the transverse beam plate and the vertical beam plate are arranged in a cross manner; a first lifting part and a second lifting part are respectively arrangedat both ends of the transverse beam plate; a third lifting part and a fourth lifting part are respectively arranged at both ends of the vertical beam plate; the first lifting part and the second lifting part are arranged in a non-collinear manner; the third lifting part and the fourth lifting part are arranged in the non-collinear manner. By adopting the lifting device, deformation of a thin-wallcylinder in lifting operation can be effectively avoided, the stress can be uniformly dispersed, lifting stability can be ensured, and potential safety hazard can be reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting devices. More particularly, the present invention relates to hoisting arrangements for thin-walled tower installations. Background technique [0002] With the rapid development of the petrochemical industry, the application of thin-walled and slender equipment is increasing, and the demand for the overall hoisting of thin-walled and slender equipment is also increasing, and the hoisting technology, equipment, safety, and Operation, construction period, etc. put forward higher and higher requirements. The traditional relatively large stainless steel thin-wall tower hoisting equipment mainly adopts two methods: one is to adopt segmental hoisting or vertical assembly, which has a long construction period, many high-altitude operations, high labor intensity, and many safety risks; The overall lifting of the lifting lugs, the local stress of the equipment and the large deflection during horizontal l...

AI Technical Summary

Problems solved by technology

The traditional relatively large stainless steel thin-wall tower hoisting equipment mainly adopts two methods: one is to adopt segmental hoisting or vertical assembly, which has a long construction period, many high-altitude operations, high labor intensity, and many safety risks; The lifting lugs are hoisted as a whole, the local stress of the equipment and the large deflection during horizontal lifting may easily cause plastic deformation of the thin-walled equipment, and even cause partial detachment or cracking of the equipment, which does not meet the requirements for safe hoisting and protection of finished products

In summary, the safety and reliability of traditional hoisting equipment for hoisting thin-walled tower equipment is poor
