Problems solved by technology

This method also has a destructive effect on the civil structure. Secondly, if the force is not uniform during the lifting process, the structure of the air duct will be damaged to a certain extent, and the phenomenon of air duct detachment often occurs. The use of hoisting to install the air duct requires more hoisting. Operators are required to operate, and the requirements for the level of operators are relatively high
Therefore, the current air duct installation has low work efficiency and high risk factor because there is no special device

Abstract

The invention discloses a special device for installing an air hose. The device comprises two lifters in same specification. Each lifter comprises a base, an expansion bracket movably connected to the base, and a plunger cylinder arranged on the base. The upper end of the plunger cylinder is connected with a connecting pin of the expansion bracket, a supporting table is fixedly arranged at the top of the expansion bracket of the lifter, baffles are fixedly connected to both sides of the supporting table, and a fine adjustment device is arranged on the upper surface of the supporting table. According to the special device for installing the air hose provided by the invention, the air hose and a civil structure are not damaged, so that the device is high in safety and agile to install, and can be installed by extremely few installation persons, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to ventilation system engineering, in particular to a special device for installing air ducts. Background technique [0002] Ducts are the piping systems used to transport and distribute air. At present, the installation of the air duct usually adopts the method of hoisting. Firstly, the hoisting rings must be installed at both ends of the air duct, and then the hoisting chains should be hung on the hoisting rings. The air duct is lifted. This method also has a destructive effect on the civil structure. Secondly, if the force is not uniform during the lifting process, the structure of the air duct will be damaged to a certain extent, and the phenomenon of air duct detachment often occurs. The use of hoisting to install the air duct requires more hoisting. Personnel are required to operate, and the requirements for the level of operators are relatively high. Therefore, the current air duct installation has low work efficiency ...
