Automatic film covering device for cylindrical pier

Abstract

The invention discloses an automatic film covering device for a cylindrical pier. The device comprises a film covering device chamber, a plastic adjusting chamber is arranged on the left wall face ofan inner cavity of the film covering device chamber, a plastic pushing telescopic rod is arranged on the left wall face of an inner cavity of the plastic adjusting chamber, a plastic pushing block isarranged on the right end face of the plastic pushing telescopic rod, and the left wall of the inner cavity of the plastic adjusting chamber is provided with a plastic adjustment motor. According to the film covering device, film covering can be conducted on the bridge pier from bottom to top, and the bridge pier film covering device is provided with a power system, so that movement can be conducted without an external power traction device, and large equipment such as a crane does not need to be used, and equipment investment is reduced; the size of the center ring can be adjusted according to the size of the pier so as to adapt to more piers, multiple pieces of plastic can be carried during film covering so as to replace the plastic in the film covering process, and thus the film covering time is saved; and air is blown to the plastic in the film covering process, so that the plastic can evenly cover the pier, and bubbles are reduced, and plastic on the upper portion of the pier canbe pressed after film covering is completed.

[0002] After the bridge pier is poured and the formwork is removed, the internal concrete will undergo hydration and exothermic reaction. In order to prevent the moisture in the pier from evaporating too quickly and causing the concrete to form cracks, it is necessary to wrap a layer of plastic film on the outside of the pier. The winding film generally requires winding from top to bottom. , that is, the lower layer is laminated to the upper layer, which can prevent the precipitated water from flowing out from the film gap. At present, when covering high bridge piers, a crane is required to lift the film roll through a rope, and a worker is transported by a crane or a ladder To the top of the bridge pier, the worker fixes the film head on the bridge pier, and then the crane gradually lowers the film roll, and at the same time, the worker shakes the rope to make the film roll around the bridge pier, so as to realize the film covering of the bridge pier. This method requires the use of a crane Large-scale equipment such as large-scale equipment requires a large investment in equipment. When laminating bridge piers in batches, the switching speed of equipment between bridge piers is full, which greatly affects the construction efficiency. At the same time, workers need to climb to the top of the bridge piers, which increases the construction risk. It is not ideal, the film is not tight and uneven, and there are some film covering devices at present, but it is difficult to automatically fix the film head on the upper end of the pier. For the upward winding method, even after the film covering is completed, the fixing effect of the film head at the upper end is not ideal. In view of the above shortcomings, the present invention improves
