Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to the maintenance construction of bridge piers. Specifically, it is a vertically movable bridge pier maintenance spraying system. Background Art

[0002] If the maintenance period of the bridge pier is not in place, it will cause uneven strength of the pier bodies adjacent to each other. Manual maintenance is dangerous and difficult, resulting in inconsistent construction progress and affecting the progress of the next process.

[0003] In the past, during the maintenance construction of bridge piers, it was necessary for workers to stand on the top of the pier and spray the maintenance liquid from above. Commonly, water was poured from the top using a water pipe. This construction method has a slow construction speed, and there are no safety measures for workers on the top of the pier, posing a safety hazard of falling from a height. For relatively high bridge piers, the pressure of the water pipe is insufficient and the water flow is small, which will waste a large amount of maintenance liquid, and the maintenance time is also relatively long. There will also be maintenance dead corners locally, and the pier body cannot be fully covered. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and provide a vertically movable bridge pier maintenance spraying system.

[0005] The utility model is realized by the following technical solutions:

[0006] A vertically movable bridge pier maintenance spraying system includes a lifting platform, a spraying platform, and a maintenance liquid tank.

[0007] The lifting platform includes a cross-shaped steel frame. Two reduction motors are installed on the cross-shaped steel frame. Two steel wire ropes are wound around the output end of each reduction motor. Anti-derailment pulleys are respectively arranged at the four corners of the cross-shaped steel frame. A pressure lift pump is installed on the cross-shaped steel frame.

[0008] The spraying platform includes a square pipe frame. A plurality of atomizing nozzles are evenly arranged on each side pipe edge of the square pipe frame. The spraying direction of the atomizing nozzles faces the center position of the square pipe frame. Suspension rings are respectively fixed at the four corners of the square pipe frame. A liquid inlet joint is arranged on any one side pipe edge of the square pipe frame.

[0009] A high-pressure water pump is arranged in the maintenance liquid tank.

[0010] The four steel wire ropes of the two reduction motors respectively bypass the corresponding four anti-derailment pulleys and are connected and fixed to the corresponding four suspension rings on the square pipe frame. One port of the pressure lift pump is connected to the liquid inlet joint on the square pipe frame through a threaded hose, and the other port of the pressure lift pump is connected to the high-pressure water pump in the maintenance liquid tank through a galvanized steel pipe.

[0011] As a preferred technical solution, the square pipe rack includes an outer square pipe rack and an inner square pipe rack. Each side pipe edge of the outer square pipe rack is connected and communicated with each side pipe edge of the inner square pipe rack through a plurality of uniformly arranged connecting pipes. Atomizing nozzles are arranged on each side pipe edge of the inner square pipe rack. Suspension rings are arranged at the four corners of the outer square pipe rack. A liquid inlet joint is arranged on any one side pipe edge of the outer square pipe rack.

[0012] As a preferred technical solution, each side pipe edge of the outer square pipe rack is connected and communicated with each side pipe edge of the inner square pipe rack through four uniformly arranged connecting pipes. Three atomizing nozzles are uniformly arranged on each side pipe edge of the inner square pipe rack.

[0013] As a preferred technical solution, the other port of the pressure boosting pump is connected with a riser connecting pipe, and the riser connecting pipe is connected with a galvanized steel pipe.

[0014] As a preferred technical solution, hoisting rings are respectively arranged at the four corners of the cross-shaped steel frame.

[0015] The utility model is scientifically designed, reasonably structured, simple to operate and convenient to use, effectively solving the problems such as inadequate maintenance of bridge piers, inability to maintain the upper part of high bridge piers, difficulty in ensuring the maintenance period, and potential safety hazards of falling from height. The atomizing nozzles of the utility model can move up and down as a whole, so as to spray the bridge pier without dead angle, having the advantages of high working efficiency and in-place maintenance. Compared with the existing traditional maintenance measures, the utility model can quickly and evenly maintain the pier body, with a high degree of mechanization and a fast maintenance spraying speed, not only improving the construction speed, but also reducing the potential safety hazards during construction, reducing the cost of manual maintenance, and having high practicability, and can be widely used in the maintenance construction of various bridge piers.
