An air-conditioning unit chassis that is convenient for hoisting

Abstract

The invention discloses an air conditioning unit chassis convenient to hoist. The air conditioning unit chassis structurally comprises an expansion bolt, a wire rope, a horizontal strip, lifting devices, a central air conditioner bearing chassis, a fixing hole, a locking strut, a spring take-up device, a lifting operation pull rope, a descending operation pull rope and a pull handle. According tothe air conditioning unit chassis convenient to hoist, the lifting devices are arranged at the four corners of the top of the central air conditioner bearing chassis, and the lifting devices are locked and fixed to the central air conditioner bearing chassis; the central air conditioner bearing chassis is hoisted on a ceiling through the wire rope and the expansion bolt at first, then the liftingdevices are controlled through the lifting operation pull rope and the descending operation pull rope, and therefore the height of the central air conditioner bearing chassis is increased and reduced;when the central air conditioner bearing chassis descends to a certain position, a central air conditioner is mounted, the frequency of vertical climbing and carrying of mounting personnel can be reduced, and meanwhile later maintenance and replacement of the central air conditioner are convenient.

Description

technical field [0001] The invention relates to an air-conditioning unit chassis which is convenient for hoisting, and belongs to the field of air-conditioning unit chassis. Background technique [0002] Central air-conditioning units are widely used in various large buildings because of their environmental protection, energy saving, excellent performance, stability and reliability. However, the central air conditioner has a disadvantage that its unit is bulky and heavy, and its safety and stability are the primary considerations during installation. At present, the air-conditioning unit is installed on the chassis. The chassis is generally composed of longitudinal supports, transverse supports and uprights. The longitudinal supports are placed in parallel. When hoisting the complete machine, generally the steel ropes are bound on the chassis first, and then the steel ropes are hung with hoisting equipment to lift the whole air-conditioning unit. However, due to the bulky ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide an air-conditioning unit chassis that is easy to hoist, so as to solve the problem that the hoisting of the air-conditioning unit chassis that is easy to hoist to the central air conditioner is relatively difficult, the labor force is large, and many safety factors need to be considered during the hoisting process. There are certain difficulties in the later maintenance and replacement of central air conditioners
