Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a high-strength mortar spraying equipment for manhole repair. Background Technology

[0002] High-strength mortar spraying equipment for manhole repair is mainly used for the repair of manholes in urban infrastructure. As manhole structures age or become damaged, traditional repair methods are often time-consuming, labor-intensive, and have limited effectiveness. High-strength mortar spraying technology can quickly and evenly cover the damaged area, providing excellent repair results and improving durability. It is widely used in urban pipeline, sewage treatment, and other projects.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing high-strength mortar spraying equipment for manhole repair cannot adapt to the needs of different spraying work because the nozzle angle cannot be adjusted. Different manholes may have different structural characteristics and defect locations. The fixed-angle nozzle may not be able to flexibly adapt to various situations, making it difficult to spray certain areas, thus affecting the repair effect. Operators may need to spend more time and effort to adjust the position of the equipment or take other measures to ensure uniform spraying, which increases the difficulty and time cost of construction. Because the nozzle angle is not adjustable, it may lead to uneven spraying thickness, resulting in problems such as missed coating and recoating, which in turn affects the quality and service life of the repaired manhole.

[0004] Therefore, this utility model proposes a high-strength mortar spraying equipment for manhole repair to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength mortar spraying device for manhole repair.

[0016] Furthermore, the support frame is provided with a fixing component, which includes a support leg fixed to the support frame near the bottom side.

[0017] The beneficial effects of adopting the above-mentioned further solutions are: the fixed components on the support frame, especially the support legs, are mainly used to improve the stability of the support frame and prevent the equipment from tilting or becoming unstable. The support legs increase the load-bearing capacity of the support frame by transferring gravity to the ground.

[0018] Furthermore, a base plate is fixedly connected to the bottom of the support leg.

The spraying assembly 2 is fixed inside the outer casing 21 at the bottom of the support rod 1. A support base 22 is fixed inside the outer casing 21, and a rotating ring 23 is rotatably connected to the support base 22. Driven by the first drive motor 24, its output end drives the first rotating block 25 to rotate. The first rotating block 25 further transmits the rotational motion through a rotatable connection to the second rotating block 26. The second rotating block 26 is connected to the rotating ring 23, and its rotation drives the rotating ring 23 to rotate, thereby realizing the adjustment of the spraying direction. The second drive motor 212 is fixed on the second rotating block 26 and drives the second rotating block 26 through its output end. A movable support plate 27 has a nozzle 28 fixed at its bottom. The nozzle 28 is connected to a hose 29, through which a delivery pump 210 delivers paint.

The nozzle 28 is connected to a hose 29, and the hose 29 is supplied with paint by a delivery pump 210. In this way, the paint is stably supplied by the delivery pump 210, and the mortar in the storage tank 211 is evenly sprayed onto the inner wall of the well by rotation. The angle of the nozzle 28 is adjusted to adapt to different spraying needs, so that the mortar can be evenly sprayed onto the inner wall of the well. The positioning component 3 is set on the support rod 1, near the top of the spraying component 2. A limit ring 32 is installed on one side of the support frame 31. The inner wall of the limit ring 32 is rotatably connected to the roller 33. The roller 33 limits the movement range of the support rod 1. The limit rod 34 is fixed with a first limit block 35 and a second limit block 36.
