[0002] In the sintering production process, the dust collector is the important equipment of guaranteeing the clean production environment, reducing the pollutant emission. Among them, the cloth bag dust collector is widely applied because of its high efficiency, stable dust removal performance. However, the high temperature environment in the sintering process constitutes the severe challenge to the normal operation of the cloth bag dust collector, especially the assembly of cloth bag and bag cage.

[0003] Because of the high temperature gas generated in the sintering process, the cloth bag is prone to deformation after being heated for a long time, and in addition to the characteristics of the cloth bag material, most cloth bags will be adhered to the bag cage. This adhesion phenomenon not only affects the dust removal effect of the cloth bag, but also greatly increases the difficulty of cloth bag replacement. In the daily maintenance of the cloth bag dust collector, the replacement of the cloth bag is a frequent and necessary work, but the existing replacement mode has many inconveniences.

[0004] Firstly, the road space around the dust collector is limited, and it is inconvenient for large cranes to occupy for a long time. Crane operation not only needs spacious space, but also may cause safety hazards to the surrounding production equipment and personnel in the use process. Secondly, the warehouse top structure of the dust collector is usually not suitable for installing fixed hoisting equipment, which further restricts the flexibility and efficiency of cloth bag replacement.

[0005] Under this condition, the replacement of the cloth bag mainly depends on manpower, not only the labor intensity is large, but also the working hours investment is considerable. The workers need to manually disassemble and install the cloth bag and bag cage in the limited space, which not only is inefficient, but also has certain safety risks.

[0006] Therefore, it is urgent to need a hoisting device which can adapt to the special working environment of the sintering cloth bag dust collector, replace the cloth bag and bag cage quickly and safely, improve the maintenance efficiency, and reduce the labor intensity and safety risk.
