Overall hoisting device and method

Abstract

The invention discloses an integral hoisting device and method. The device comprises two towers, a U-shaped beam,a hydraulic jacking system, a connection beam and a tail crane, wherein rails in the perpendicular direction are arranged along the towers; the two towers are separated from each other, and the heights of the towers are lower than that of equipment to be hoisted; the equipment to be hoisted comprises a main hoisting lug arranged at the periphery of the upper part and a tail hoisting lug arranged at the periphery of the bottom; the U-shaped beam is arranged between the two towers, and can move up and down along the rails under driving of the hydraulic jacking system; the U-shaped beam is provided with a hoisting ring; the hoisting ring is connected to the main hoisting lug; the hydraulic jacking system can crawl along the rails to drive the U-shaped beam to move up and down along the rails; the connection beam is arranged between the tops of the two towers, and can be in a closed state or a non-closed state; in the closed state, the connection beam is connected with the tops of the two towers; in the non-closed state, the connection beam is separated from any one of the two towers; a tail hoisting appliance of the tail crane is connected to the tail hoisting lug of the equipment to be hoisted.

Description

technical field [0001] The invention relates to a hoisting device and method, in particular, the invention relates to an overall hoisting device and method using a U-shaped beam mode. Background technique [0002] With the rapid development of the national energy and chemical industries, the energy level of domestic oil refining and ethylene plants has become larger and larger in the past two years, and the large equipment has become higher and heavier. Usually, large-scale equipment is hoisted in sections, using large-tonnage crawler cranes, which increases the high-altitude butt welding work, which has a high risk factor, difficult construction, long hoisting time, and high dispatch costs for large-tonnage crawler cranes. The height of the traditional tower must be higher than the height of the equipment. When hoisting super-long equipment, the height of the tower also needs to be very high. At the same time, the energy level of the tail-sliding crane is also relatively hi...

AI Technical Summary

Problems solved by technology

For hydraulic lifting, with the use of steel strands, steel embroidery will be generated, which will directly affect the locking effect of the clips, and at the same time affect the quality of the clips, and even need to replace the clips during hoisting, so the equipment cannot be lifted continuously
