Abstract

The invention discloses a lifting method for large-scale tower equipment, comprising the following steps of: 1) welding two connecting lifting lug plates and a bottom lifting lug plate on the base of the equipment, wherein the two connecting lifting lug plates are respectively arranged at two sides of the base of the equipment, and the bottom lifting lug plate is arranged between the two connecting lifting lug plates; a pipe clamp lifting structure is fixed at the top of the equipment and comprises a pipe clamp fastened on an equipment tower cylinder, and the pipe clamp is connected with two top lifting lug plates by a ring plate; the two top lifting lug plates are respectively arranged at two sides of the equipment tower cylinder, are in parallel with the equipment tower cylinder, and are respectively opposite to the two connecting lifting lug plates; and tensioning steel wire ropes are arranged between the connecting lifting lug plates and the top lifting lug plates, which are opposite to each other; 2) horizontally lifting equipment by two lifters; 3) lifting the top of the equipment by one lifter; and 4) lifting the equipment to a preset position. The method is safer, more efficient, and more convenient to operate, and the lifting auxiliary materials and the preset time and cost can be saved, so that the lifting method has high economical efficiency and practical applicability.

Description

technical field [0001] The invention relates to a hoisting method, in particular to a hoisting method of large-scale tower equipment. Background technique [0002] Large-scale tower equipment is one of the main equipment for onshore terminals, such as regeneration towers, desulfurization towers, scrubbers, and deethanizers. The outstanding features of these equipment are tall towers, thin walls, and low tower strength. Manufactured and hoisted in place on site. Due to the particularity of these large-scale tower equipment, accurate and safe hoisting scheme is a difficult problem in design. [0003] At present, the common hoisting method for large-scale tower equipment is to make a hoisting auxiliary reinforcement frame to strengthen the tower body, and at the same time use 4 sets of hoops to hold the tower body tightly, connect and fix the hoops with the hoisting reinforcement frame, and set the hoisting point on the top of the tower. Hanging on the frame. This method can...
