Description

Mobile cantilevered platform

technical field

The invention relates to the technical field of building construction, in particular to a mobile suspension platform.

Background technique

At present, with the development of society, there are more and more shapes of various special-shaped building structures with curved surfaces. When the construction work is carried out in the overhanging area, for example, the curtain wall decoration of the outer wall or the gluing work after the curtain wall decoration, etc., if Cantilevered scaffolding is used, which is difficult to erect, low in safety, poor in flexibility, and cannot be moved as a whole. It needs to be erected and dismantled repeatedly, which is labor-intensive and time-consuming. A large number of scaffolds are required to provide sufficient working surfaces to meet the needs of flow-through construction in different processes. Not only is a lot of labor wasted, but also high scaffolding rental fees are generated, and the cost is high.

In the prior art, there is also a form of cantilevered platform frame to replace the traditional scaffolding. For example, the invention patent with the publication number CN109763423A discloses an adjustable split-type mobile hanging basket and an operation method for bridge maintenance. It includes two supporting beams, a counterweight platform, a construction operation platform, a walking device and a hanger. When the invention is used in actual engineering, the walking counterweight platform with locking function is placed on the inner side of the bridge guardrail and separated from the guardrail. A certain distance is used to make the counterweight block provide a greater moment, and the construction operation platform on the other side is suspended outside the guardrail, and the guardrail is used as the fulcrum of the two supporting beams. According to different bridge types and guardrail sizes, the hanging The basket supporting beam can be stretched horizontally, and the hanger can be stretched vertically to meet the needs of construction operations. By pushing the walking counterweight platform, the hanging basket can be moved to the position where maintenance is required, and the walking basket can be moved by the split pin fixed on the walking wheel cover. The guardrail and the lower flange can be maintained and overhauled on the operating platform by locking the wheels. However, this invention needs to place a counterweight platform inside the bridge guardrail to increase the self-weight of the mobile hanging basket to prevent the mobile hanging basket from turning over, but because the counterweight platform is heavier, the self-weight of the mobile hanging basket is naturally increased, so that the mobile hanging basket moves It is inconvenient, and increasing the counterweight also increases the cost, so how to find a cantilever platform that can be quickly and easily fixed is particularly important.

Contents of the invention

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide a mobile cantilevered platform, which can reduce the difficulty of installing and fixing the cantilevered platform, and is convenient for assembly, disassembly and transfer.

The multiple longitudinal beams are parallel to each other and multiple The two ends of the longitudinal beam are respectively welded on the two beams; the upper ends of the two rear columns are welded with vertical hollow screws, the screw is provided with internal threads, the screw is covered with a push rod, and the outer wall of the push rod is processed with external threads. The internal threaded hole of the rod and the screw rod is threadedly matched, so that the upper end of the push rod can lean against the bottom of the superstructure floor.

When the mobile cantilevered platform is in use, place the stand on the floor of the building, move the cantilevered platform to the required construction work position, and make the cantilevered working frame protrude from the cantilever outside the building. Pick the working area, and then turn the ejector rod clockwise or counterclockwise so that the ejector rod rotates along the internal thread of the screw rod. While the ejector rod is rotating, the ejector rod moves upwards. When the upper end of the ejector rod moves upwards and rests against the superstructure When the bottom of the floor is at the bottom of the floor, the cantilevered platform is fixed on the floor of the building as a whole. Since the ejector rod is completely in contact with the floor, the cantilevered platform will not overturn.
