Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining facilities technology, specifically to a mobile nozzle for a mining wet spraying trolley. Background Technology
[0002] Currently, wet shotcrete trolleys are increasingly being used in underground shotcrete support operations. The trolley's shotcrete pipes and nozzles are fixed to a robotic arm, and shotcreting can only be extended to the work face via remote control. Due to the limited space in underground metal mines, wet shotcrete trolleys cannot reach some confined areas. Areas inaccessible by wet shotcrete operations are often still handled by dry shotcrete, which not only increases the labor intensity of workers, worsens the working environment, and reduces production efficiency, but also results in substandard shotcrete quality. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a mobile nozzle for a mine wet spraying trolley, which solves the problem that the spraying pipes on the wet spraying trolley cannot extend to the working face, resulting in the only option for dry spraying, which leads to high labor intensity for workers, poor working environment, low production efficiency, and substandard spraying quality.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A mobile nozzle for a mining wet spraying trolley, characterized in that it includes a detachable conversion joint, a detachable diverter, and a connecting clamp. The detachable conversion joint is connected to the slurry outlet of the conveying pipe via the connecting clamp. The detachable diverter is sleeved on the detachable conversion joint. The detachable diverter is sleeved with the spraying pipe. The connection between the detachable diverter and the spraying pipe is via the connecting clamp.
[0006] The connecting clamp consists of a right clamp and a left clamp. The right clamp and the left clamp are hinged at one end, and the other end of the left clamp is provided with a safety buckle. The end of the safety buckle is provided with a handle.
[0007] The beneficial effects of this utility model are:
[0008] (1) When this utility model is used in a narrow area, the fixed nozzle of the wet spraying trolley is transformed into a mobile nozzle by a detachable conversion joint and a detachable diverter, which improves the quality of spraying. The length of the spraying pipe is selected according to the on-site operation distance, so that the wet spraying operation covers all areas of the underground metal mine. The original fixed nozzle remains unchanged during normal use.
[0009] (2) The connecting clamp of this utility model is divided into a right clamp and a left clamp. The left and right clamps are hinged at one end, and the other end of the left clamp is provided with a safety buckle. The end of the safety buckle is provided with a handle. When using the connecting clamp, after the left and right clamps are fixed, the safety buckle is locked and the handle is close to the right clamp. When removing, the handle is turned to release the safety buckle from locking, which effectively fixes the interface and improves production efficiency. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes a detachable conversion joint 1, a detachable diverter 2, and a connecting clamp 3. The detachable conversion joint 1 is connected to the slurry outlet of the conveying pipe through the connecting clamp 3. The detachable diverter 2 is sleeved on the detachable conversion joint 1. The detachable diverter 2 is sleeved on the slurry spraying pipe 4. The connection between the detachable diverter 2 and the slurry spraying pipe 4 is connected through the connecting clamp 3.
[0018] like Figure 3 As shown, the connecting clamp 3 is divided into a right clamp 3-1 and a left clamp 3-2. The right clamp 3-1 and the left clamp 3-2 are hinged at one end, and the other end of the left clamp 3-2 is provided with a safety buckle 3-3. The end of the safety buckle 3-3 is provided with a handle 3-4.
[0019] When using this utility model in a confined area, first disconnect the original vehicle's spraying material delivery pipe from the nozzle 5, and disconnect the two hoses on the original vehicle's distributor. Then connect the detachable adapter 1 to the detachable distributor 2. Next, connect the detachable adapter 1 end of this connector to the original vehicle's material delivery pipe using the large connecting clamp 3. Connect the other end of this connector to the spraying pipe 4 using the small connecting clamp 3. Finally, connect the nozzle 5 and the spraying pipe 4 with bolts. The length of the spraying pipe 4 is selected according to the on-site working distance to achieve the purpose of a movable nozzle 5. The entire disassembly and installation process is convenient to operate.
[0020] When using the connecting clamp 3, the right clamp 3-1 and the left clamp 3-2 are engaged at the interface, locking the safety buckle 3-3 at the other end of the left clamp 3-2. The handle 3-4 is close to the right clamp 3-1. When removing, turn the handle 3-4 to release the locking of the safety buckle 3-3, thereby removing the connecting clamp 3.
[0021] This method reduces the labor intensity of workers, improves the working environment, increases production efficiency, and also increases the strength of the support structure.
[0022] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
