Problems solved by technology

One end face of each box girder used in high-speed railways needs to be painted with polyurethane waterproof coating for an area of ​​7.7 square meters. The standard requires a coating thickness of 4mm to 5mm. Generally, it needs to be painted about 8 times. Therefore, the two ends of each box girder need to be brushed in total. 16 times of polyurethane waterproof coating, 123 square meters, heavy workload, and low construction efficiency; in addition, high temperature construction, cleaning agent volatilization, and high-altitude operations also caused hazards to the health of personnel

Abstract

The invention discloses a box girder end face spraying device and a spraying method. The device includes a traveling mechanism, a feeding mechanism, a lifting level adjusting mechanism, a nozzle mechanism and a control module. The traveling mechanism includes a vehicle body and a crawler walking mechanism, and a lifting level adjusting mechanism It includes a lifting mechanism and a horizontal sliding mechanism, the horizontal sliding mechanism is provided with a telescopic and rotating mechanism, the telescopic and rotating mechanism includes an electric push rod and a rotating head, and the spray head mechanism is installed on the rotating head; the method includes the following steps: a. 1. Division of the end face of the box girder; 2. Spraying of the end face area of ​​the first box girder; 3. Spraying of the end face area of ​​the second box girder; 4. Spraying of the end face area of ​​the third box girder; The next spraying of the beam end face, until the spraying of the box girder end face is completed. The invention has reasonable design, can quickly complete the spraying of the waterproof coating, and improves the construction efficiency, spraying quality and personnel safety.

Description

A kind of box girder end face spraying device and spraying method technical field The invention belongs to the technical field of box girder end face spraying, particularly relate to a kind of box girder end face spraying device and spraying method. Law. Background technique In the construction of high-speed railway and expressway, a large number of box girder structures are adopted, and the box girder that is prefabricated in the beam field is sprayed on the end face. Applying polyurethane waterproof coating to form a waterproof layer is an indispensable process. This layer of waterproof material is the protection of the box girder tension cable layer, relying on a protective layer to resist rust damage. At present, the spraying of the waterproof layer of the end face of the box girder is completely by manual operation, that is, firstly by artificial preparation of two-component polyurethane Ester waterproof coating, and then use hand tools such as rollers, brush...
