A hoisting system and hoisting method for hoisting tall anaerobic tanks with low-slung group of suspenders

Abstract

The invention provides a hoisting system and method for hoisting a high and large anaerobic jar body through a low davit group. The hoisting system comprises an anaerobic jar foundation, wall boards, davits, davit lugs, wall board lugs and electric chain blocks. The tops of the davits are provided with lifting lug mounting slots vertically in a cut mode. The davit lugs are inserted into the lifting lug mounting slots. The davit lugs are provided with davit lug holes. The wall board lugs are provided with wall board lug holes. The electric chain blocks and the davits are identical in number. The electric chain blocks are hung between the davits and the wall boards. One end of each electric chain block penetrates through the corresponding davit lug hole, and the other end of each electric chain block penetrates through the corresponding wall board lug hole. According to the hoisting method, an inverted hoisting manner is adopted. The hoisting system meeting the hoisting security specifications and regulations is adopted to conduct inverted construction. The hoisting system is convenient, fast and safe to use. It can be effectively guaranteed that the jar body is stably lifted up by lifting the jar body just by the height of a circle of the wall boards every time. The cost is lowered. The construction cycle is shortened. The environment is protected. Green construction and almost zero emission are realized. The construction quality is improved. Welding operations are all conducted on the ground.

Description

technical field [0001] The invention relates to a hoisting system for a tall anaerobic tank body and a hoisting construction method thereof. Background technique [0002] The anaerobic tank is an efficient multi-stage internal circulation anaerobic reaction tank, which has the characteristics of less land occupation, high organic load, stronger impact resistance, more stable performance, and simpler operation and management. The existing tall anaerobic tank has a large diameter, a large height, a heavy overall weight, and great difficulty in construction. The conventional construction method is to use segmented production, and finally use large-scale hoisting machinery to hoist from the bottom layer by layer and install the construction method. This construction method has a long cycle, increased probability of high-altitude operations, increased safety risks for operators, increased investment in high-altitude operations, high production costs for required production sites...
