Description

Hoisting device for three-way pipeline Technical Field The utility model relates to a lifting device, in particular to a lifting device for a three-way pipeline. Background In a central air conditioning system, a three-way pipeline is used as a key component for realizing air flow distribution, and the performance quality of the three-way pipeline directly influences the operation efficiency and the use effect of the whole air conditioning system. Currently, existing central air conditioning tee pipes are usually installed by fixing them on brackets or hoisting them by using hanging rods. Specifically, the tee bracket is firstly installed, the tee bracket and the wall surface are nailed and fixed together by using screws, then the air pipe is connected to the tee bracket, and if necessary, the tee bracket and the wall surface are connected by using a retaining ring or a sealing material. When the lifting rod is used for lifting the inner machine, the three-way pipeline is fixed by arranging the lifting clamp at a proper position, so that the stability and the position accuracy of the three-way pipeline are ensured. As described above, the existing hoisting mode has relatively poor adaptability to different structures and spaces, is limited by factors such as wall structures, space heights and the like, and cannot adjust the heights of the three-way pipelines at any time. Disclosure of utility model The utility model mainly aims to provide a hoisting device for a three-way pipeline, so that the hoisting device is better suitable for different floor heights and has stronger adaptability. In order to achieve the above purpose, the utility model provides a hoisting device for a three-way pipeline, which comprises a plurality of expansion bolts, a hoisting plate and a hoisting frame, wherein the expansion bolts are uniformly distributed on two sides of the hoisting plate, the expansion bolts on two sides of the hoisting plate are arranged at intervals, extrusion supporting pieces are arranged at the bottoms of the expansion bolts, the extrusion supporting pieces jointly extrude the hoisting plate on the top of a floor, the extrusion supporting pieces can rotate relative to screw rods of the expansion bolts, and the hoisting frame is detachably arranged below the hoisting plate. Preferably, the hanger comprises two hanger rods, a U-shaped frame and a cover plate, external threads are respectively arranged at two ends of the hanger rods, the top ends of the hanger rods are in threaded connection with the hanger plates, the cover plate is buckled at the opening end of the U-shaped frame, the hanger rods fix the cover plate and the U-shaped frame together, the cover plate and the U-shaped frame form a square frame, and the square frame is sleeved outside the three-way pipeline. Preferably, the expansion bolt comprises an expansion sleeve, a screw rod, a screw cap, an extrusion gasket and an extrusion supporting plate, one end of the screw rod is fixedly connected with the screw cap, the other end of the screw rod is screwed into the expansion sleeve, the extrusion supporting plate is positioned above the extrusion gasket, and the extrusion gasket is positioned between the extrusion supporting plate and the screw cap. Further preferably, the extrusion support plate is in a fan ring shape, a perforation is arranged near the large arc end of the extrusion support plate, and the extrusion support plate is rotationally connected with the screw rod through the perforation. The beneficial effects of the utility model are as follows: 1. distributed expansion bolt + spacing arrangement design The lifting device supports the lifting plate through the expansion bolts which are uniformly distributed on the two sides and are arranged at intervals, compared with the traditional single-point suspension or single-side fixation, the lifting device is more uniform in stress, improves the vibration load when bearing the pipeline to run, and avoids loosening or falling risks caused by long-term use. 2. The adaptability is strong: The length of the hanging bracket is adjusted, so that the hanging bracket can be better adapted to different floor heights and sizes and weights of three-way pipelines, and has strong adaptability.
