Concrete pier spraying curing device

Abstract

The invention relates to the field of pier curing, in particular to a concrete pier spraying curing device. The concrete pier spraying curing device includes a lifting truss, a top supporting frame and a winch, wherein the lifting truss is arranged around a pier, the top supporting frame is provided with a pulley block, the winch is fixedly arranged on the top supporting frame, and the winch controls the lifting truss to ascend and descend by retracting and releasing steel cables; a plurality of sliding blocks capable of moving horizontally left and right are uniformly distributed on the lifting truss, and the sliding blocks are provided with atomizing sprayers, and the atomizing sprayers are connected with a water supply system; the lifting truss is provided with a plurality of supportingwheels, the supporting wheels are in contact with the pier, and the supporting wheels rotate under the frictional action of the side wall of the pier during the ascending and descending process of the lifting truss; and the lifting truss is provided with a transverse movement transmission mechanism, and when the supporting wheels rotate, the sliding blocks are driven to reciprocate horizontally through the transverse movement transmission mechanism. According to the concrete pier spraying curing device, the spraying area of the nozzle is greatly increased, the spraying effect is better, watersources are saved, maintenance is easy, and the advantage of low cost is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge pier maintenance, in particular to a spray maintenance device for concrete bridge piers. Background technique [0002] The intermediate supporting structures of multi-span bridges are called piers. Bridge piers are divided into solid piers, column piers, and bent piers. According to the plane shape, it can be divided into rectangular piers, pointed piers, round piers, etc. The materials of building piers can be wood, stone, concrete, reinforced concrete, steel and so on. Bridge piers are divided into two categories: gravity piers and light piers. Among them, gravity piers are generally concrete structures. After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydra...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, it is a common way to spray the bridge pier with a hoisted nozzle, which has the advantages of simple installation and high degree of automation, but also has many disadvantages, such as: 1. The spraying is not uniform, and the nozzle sprays directly There is more water in the place, and the place where the nozzle can't spray is relatively dry. If the density of the nozzle is increased, a large amount of water is needed, especially in the place where water is scarce; 2. The sprayed water will form "Runoff" flows down the pier body of the pier. Although it can be recycled, there is still a large waste of resources. The water sprayed out is not well utilized for the maintenance of the pier; 3. In the environment of hot weather and dry air In the middle, the moisture is increased too fast, and the water resource consumption is large
