Grouting manipulator

Abstract

The invention relates to a grouting manipulator. The grouting manipulator comprises a chassis, a revolving mechanism, an arm support, a spray head device, a hydraulic system and an electric system, wherein the revolving mechanism, the hydraulic system and the electric system are arranged on the chassis; the arm support is hinged to the revolving mechanism, and can be driven to rotate relative to the chassis by using the revolving mechanism; the spray head device is arranged at the front end of the arm support, and is connected with a concrete conveying pipe, a compressed air conveying pipe and a setting accelerator conveying pipe of a wet sprayer; the electric system and the hydraulic system are used for controlling the actions of the arm support and the spray head device. By adopting the grouting manipulator, efficient matching with the wet sprayer is realized, operating personnel can carry out grouting work conveniently, the spray height and position can be adjusted conveniently, heavy labor work of manual holding of a spray head is liberated, the spray range is enlarged, and the construction quality is improved. Compared with a large-sized grouting vehicle, the grouting manipulator has the advantages of simple structure, small size, lower cost, suitability for construction of certain medium and small-section tunnels, and more extensive application occasions.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a spraying manipulator. Background technique [0002] At present, concrete spraying construction technology is divided into two types: dry spraying method and wet spraying method. However, dry spray technology has disadvantages such as high rebound rate, large dust, unguaranteed spray intensity and serious health hazards to operators, and is gradually being replaced by wet spray technology. Wet spraying technology refers to the use of compressed air to transport the ready-mixed concrete mixture to the nozzle through the pipeline, form a bundle after being mixed with an accelerator, and spray it at a high speed to the sprayed surface to condense and harden, thereby forming a concrete support layer. [0003] In the concrete spraying process, in most cases, the manual spraying method is still used, that is, the operator holds the spray head and the delivery hose to spray the co...

Problems solved by technology

[0003] In the concrete spraying process, in most cases, the manual spraying method is still used, that is, the operator holds the spray head and the delivery hose to spray the construction work surface, but this method is difficult to control the spraying quality of the concrete, and the concrete is easy to rebound and collapse. fall, resulting in poor construction quality, low construction efficiency, and high labor intensity for workers

Workers can also use the spraying bracket of the wet spraying machine to assist spraying. This method reduces the labor intensity of workers to a certain extent, but it is still necessary for workers to operate the spray head and adjust the spraying height during the construction process, and the construction quality is still difficult to be guaranteed.

In addition, during the construction process, the operator is relatively close to the construction surface, and is vulnerable to injury to the operator due to the rebound of the falling material on the construction surface.

[0004] In addition to manual spraying, large-scale spraying vehicles can also be used for construction in engineering, which costs a lot of money and is easily limited by the construction space, so it is not suitable for construction in small and medium-sized tunnels

On the other hand, since the spraying truck itself has a complete pumping system, some existing spraying equipment will be idle, wasting the existing resources
