Lifting device and lifting method for movable positive plates for electrostatic precipitation

Abstract

The invention discloses a lifting device and lifting method for movable positive plates for electrostatic precipitation. The lifting device comprises two double-hook lifting appliances, wherein each double-hook lifting appliance comprises a lifting cross beam, two lifting lugs are symmetrically arranged at the bottoms of two ends of the lifting cross beam, steel wire ropes are hung on the two lifting lugs, and the bottom ends of the steel wire ropes are connected with double-hook hooks respectively. According to the invention, after being combined into a whole, the movable positive plates are integrally lifted by the double-hook lifting appliances, so that the number of construction personnel and the difficulty of high-altitude operation are reduced, the problems that negative barbed wires are damaged easily and personnel and equipment hurt each other easily when the movable positive plates are lifted in place one by one are avoided, the construction cost is greatly saved, and the construction efficiency is improved. Therefore, the lifting device and the lifting method are conductive to achieving expected goals in safety, construction period, cost and efficiency and are suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of hoisting and construction of a mobile pole plate of an electric dust collector and similar chain-suspended equipment, in particular to a hoisting device and a hoisting method for a mobile anode plate of an electric dust collector. Background technique [0002] The mobile electrode type electrostatic precipitator is a new type of environmental protection equipment in recent years. In the existing technology, the lifting method of the mobile anode plate is usually: first hang the chains on both sides on the drive sprocket, and then install the mobile anode plate in a single piece to the chain. According to this hoisting method, the following problems will occur: [0003] 1. Due to the large number of mobile anode plates, the tower crane is used for repeated hoisting times, and the investment in mechanical shifts is large; and the cathode barbed wire has been installed in place. If the tower crane is used fo...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the large number of mobile anode plates, the tower crane is used for repeated hoisting times, and the investment in mechanical shifts is large; and the cathode barbed wire has been installed in place. If the tower crane is used for hoisting, the pole plate is easy to shake when it is in place. Stable, easy to damage the cathode burr wire

[0004] 2. If the mobile anode plate is hoisted in place manually, the construction personnel need to stand around the prickly wire, and personnel must cooperate with the anode plate to hoist in place, which not only increases the number of labor and the difficulty of high-altitude operations, but also easily causes the interaction between personnel and equipment. harm

[0005] 3. If the mobile anode plate is tied down with a brown rope, the workload will be heavy, and the personnel will need to climb and install it in layers, which will affect the construction efficiency; personnel standing around the pierce line will easily cause personal injury accidents

[0006] 4. The mobile pole plate after hoisting needs to connect the chain into a ring in time, which affects the construction efficiency; if it is not connected into a ring in time, the chain is likely to slide on the sprocket, which is likely to cause serious consequences of machine crash and death
