Abstract
Description
Technical Field
[0001] The invention relates to the technical field of spraying equipment, in particular to a concrete pipe segment spraying device. Background Art
[0002] Concrete segments, also known as reinforced concrete segments, are the basic units of tunnel prefabricated lining rings made of reinforced concrete as the main raw material. They have high strength, good durability, easy processing and low cost. There are mainly reinforced concrete segments, steel fiber concrete segments, etc. Among them, reinforced concrete segments are the most commonly used type.
[0003] Among them, the spraying equipment used for concrete segments is a type of equipment for spraying and curing precast concrete segments. Generally, a power drive device drives the nozzle or spray pipe to move up and down along a track or bracket. At the same time, a water pump pressurizes the water in the water tank and transports it to the nozzle. The nozzle sprays the water evenly on the surface of the pier. During the lifting process, the nozzle continues to spray water, thereby achieving comprehensive and uniform spraying of the piers at different heights.
[0004] Existing equipment for lifting spray maintenance of bridge piers generally drives a chain or wire rope through a motor to move a frame equipped with a sprinkler up and down along a track outside the pier. During the movement, the sprinkler sprays water to maintain the pier. However, during the maintenance process, due to the irregular shape of the pier, the angle of the sprinkler, the water pressure and other factors, there is no good guarantee for uniform spraying on the entire pier surface, especially for the concave and convex surface at the middle joint of the pier, where water may not be sprayed in place on both sides of the concave surface. Summary of the invention

[0017] Preferably, the rotation of the roller drives the rotating rod to rotate, and then the multiple sets of first spur gears drive the large gear to rotate, so as to transmit power and reduce energy consumption.
[0018] The present invention is further configured such that the large gear is located in the housing, and a second spur gear is sleeved on the inner wall of the large gear, and a first spur gear is also disposed at the other end of the second spur gear.
