Description

Rotatable film health preserving device of high pier stud mound top of bridge

Technical Field

The utility model relates to a bridge pier stud construction technology specifically is a rotatable formula film health preserving device in high pier stud mound top of bridge.

Background

In the construction of bridge pier stud, along with the continuous promotion of pier stud height, carry out the film health preserving to high pier stud and be especially important. Under the prior art, the film curing of high pier columns is generally carried out by matching a truck crane with an operation mode of manually laying a film. Practice shows that the film health preserving technology has the following problems due to the limitation of the principle of the film health preserving technology: firstly, the film curing technology needs to occupy the truck crane for a long time, so that the occupancy rate of the truck crane is too high. Secondly, the film curing technology requires curing personnel to walk back and forth on the pier top of the high pier stud, so that the operation safety is poor. Thirdly, the film curing technology is difficult to ensure the uniformity of film laying, thereby causing poor curing effect. Therefore, a brand-new film curing device is needed to be invented to solve the problems of too high occupancy rate of a truck crane, poor operation safety and poor curing effect caused by the existing high pier column film curing technology.

Disclosure of Invention

The utility model discloses a solve present high pier stud film health preserving technique and lead to the occupancy of mobile crane too high, the operation security is poor, the not good problem of health preserving effect, provide a rotatable formula film health preserving device in high pier stud mound top of bridge.

The utility model discloses an adopt following technical scheme to realize:

a rotatable film health preserving device for a pier top of a high pier column of a bridge comprises a rope winding shaft, a crank, a bearing, an inclined stay bar, a rope penetrating pipe, a steel wire rope, a plastic winding film and a balancing weight; wherein the rope winding shaft is vertically arranged; the crank is fixedly connected to the center of the lower end face of the rope winding shaft; the number of the bearings is two; the inner ring of the first bearing is fixedly assembled at the upper end of the side surface of the rope winding shaft; the inner ring of the second bearing is fixedly assembled at the lower end of the side surface of the rope winding shaft; the number of the inclined supporting rods is three; the upper end surfaces of the three inclined supporting rods are fixed with the lower end surface of the outer ring of the second bearing, and the three inclined supporting rods are arranged around the axis of the second bearing at equal intervals; the rope threading pipe is horizontally arranged and is vertically fixed at the upper part of the side surface of the rope rolling shaft; the edge of the inner end pipe orifice of the rope threading pipe is provided with a rope threading notch in a through way; the steel wire rope is wound on the side surface of the rope winding shaft, and the leading-out part of the steel wire rope sequentially passes through the rope threading notch and the rope threading pipe and then falls downwards; the plastic rolling film is sleeved at the lower part of the leading-out part of the steel wire rope; the balancing weight is hung at the lower end of the leading-out part of the steel wire rope.

When the device is used, the lower end faces of the three inclined support rods are fixed with the pier top of the high pier stud. The specific using process is as follows: health preserving personnel stand at the mound top of high pier stud to slowly rotate the crank, the crank drives the serving and carries out slow rotation, and the serving drives the stringing pipe and carries out slow rotation, and the stringing pipe drives plastics rolling up film and balancing weight through wire rope and carries out slow rotation around high pier stud together. Based on the slow rotation of the plastic roll film, the leading-out part of the plastic roll film can be wound and laid on the outer surface of the high pier stud, so that the high pier stud is subjected to film curing.

Based on above-mentioned process, compare with current high pier stud film health preserving technique, a rotatable formula film health preserving device in high pier stud pier top of bridge through adopting brand-new structure, realized carrying out the film health preserving to high pier stud, possessed following advantage from this: one of the two, the utility model discloses need not to use the truck crane, effectively reduced the occupancy of truck crane from this. And secondly, the utility model discloses need not the health preserving personnel and make a round trip to walk at the mound top of high pier stud, effectively improved the operation security from this. Thirdly, the utility model discloses fully guarantee the homogeneity that the film laid, make the health preserving effect better from this.

Further, the rope threading pipe is a telescopic stainless steel pipe. During the use, through the length to the stringing pipe regulation that stretches out and draws back, can make the utility model is suitable for a high pier stud of different diameters.

The utility model discloses rational in infrastructure, design benefit have effectively solved current high pier stud film health preserving technique and have leaded to the occupancy of mobile crane too high, the operation security is poor, the not good problem of health preserving effect, are applicable to the high pier stud health preserving of bridge.
