Description

Lifting device for assembled decoration suspended ceiling and application method thereof Technical Field The invention relates to the technical field of devices for decoration, in particular to a lifting device for an assembled decoration suspended ceiling and a use method thereof. Background In the field of modern construction, assembly type decoration is widely applied because of the advantages of high efficiency, environmental protection, controllable quality and the like, and as the suspended ceiling working surface is generally higher, how to safely and efficiently lift a large-size suspended ceiling plate to a designed elevation and accurately position and fix the suspended ceiling plate is a challenge faced in the construction process. At present, the common lifting device on the market mainly comprises a movable base and a lifting table capable of vertically lifting on the movable base, so that the problem of vertical conveying of the suspended ceiling plate is solved. Meanwhile, when the large-size whole plate suspended ceiling is lifted, the whole-process level of the whole plate needs to be ensured, the existing device lacks an adjusting mechanism, the inclination and the blockage and the exceeding of the positioning deviation are easy to cause in the lifting process of the whole plate, and the integrated requirements of stable lifting, flexible displacement, accurate fine adjustment and safe positioning of the large-size whole plate are difficult to be met. For example, chinese patent publication No. CN118564021B discloses a lifting system for assembled decoration suspended ceiling, which drives a suspended ceiling plate to be attached to a base plate through a lifting seat, and controls a servo motor to drive a screw rod to rotate, so that symmetrical moving blocks arranged on two sides of the surface of the screw rod relatively move, and when the moving blocks move, a step plate is driven to horizontally move, a pneumatic gun on the surface of the step plate automatically fixes the periphery of the suspended ceiling plate, and the injection direction of a fixing needle is completely and vertically injected from the bottom of the suspended ceiling plate uniformly, so that the fixing strength of the suspended ceiling plate is improved, four sides of the suspended ceiling plate can be simultaneously fixed, and the labor intensity of operators is greatly reduced. Although the proposal can lift and automatically fix the suspended ceiling plate, the suspended ceiling plate is lack of adjustment on the levelness of the suspended ceiling plate and is easy to interfere with a wall body in a narrow passage.
