Description

Technical Field

[0001] The utility model relates to the field of tunnels, and more specifically, to a tunnel repair and filling device. Background Art

[0002] A tunnel is an engineering structure buried in the ground and is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. The structure of a tunnel includes two parts: the main building and the auxiliary equipment. The main building consists of the tunnel body and the portal, and the auxiliary equipment includes refuge bays, fire protection facilities, emergency communication, and waterproof and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] Currently, during the maintenance of tunnels, there may be cases of hollowing and cracking in some areas. Therefore, during the repair process, a syringe gun is used to fill the hollow areas with mud to achieve tunnel repair. However, most of the nozzles of common syringe guns are fixedly arranged, and in actual injection processes, they may not be able to contact the area to be injected in special spatial structures, resulting in inconvenient injection operations. Therefore, we have made improvements and proposed a tunnel repair and filling device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tunnel repair and filling device, which solves the problem that the nozzle of the existing tunnel repair and filling device is inconvenient to use in some special filling environments.

[0015] As a preferred technical solution of the present application, the cross-section of the outer end of the second hard tube is trapezoidal, and the shape of a side wall of the connecting cavity is adapted to the cross-section shape of the outer end of the second hard tube.

[0016] As a preferred technical solution of the present application, the guide assembly includes a handle connected to the surface of the tail, a support rod connected to the middle of the handle, and a universal ball connected to one end of the support rod;

[0017] Wherein, the support rod is movably connected to a telescopic piece connected to the gun seat through a universal ball.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0038] As Figures 1-5 shown, this embodiment provides a tunnel repair filling device, including a gun body 1 and a gun seat 2. The gun body 1 and the gun seat 2 are connected end to end. A groove 11 is formed inside the gun body 1 for placing the filling pipe 12 therein. A delivery pipe 13 is provided on one side of the gun body 1 away from the gun seat 2 for connecting and assembling with the filling pipe 12;

[0039] One end of the delivery pipe 13 is connected with a filling component 3 for outputting and filling tunnel repair materials. Among them, a guiding component 4 is provided on one side of the filling component 3 for connecting with the gun seat 2 to realize the adjustment of the filling angle of the filling component 3;

[0040] The filling component 3 includes a first rigid pipe 31 and a second rigid pipe 32. A corrugated hose 33 is connected between the first rigid pipe 31 and the second rigid pipe 32. One end of the first rigid pipe 31 is connected to the corresponding delivery pipe 13, and one end of the second rigid pipe 32 is connected to a filling nozzle 34;

[0041] Due to the function of the corrugated hose 33, the angle between the first rigid pipe 31 and the second rigid pipe 32 can be freely adjusted to meet the requirement that the filling nozzle 34 can swing freely to adjust the filling while keeping the gun body 1 stationary during special filling operations.

[0042] The filling nozzle 34 includes a nozzle part 340 and a tail part 341. A connection cavity 342 is provided inside the tail part 341, and one end of the second rigid pipe 32 is slidably arranged inside the connection cavity 342;

[0043] The outer end cross-section of the second rigid pipe 32 is trapezoidal, and the shape of one side wall of the connection cavity 342 is adapted to the outer end cross-section shape of the second rigid pipe 32;

[0044] As Figure 4 shown, at this time, a part of the second rigid pipe 32 is exposed outside, and the corrugated hose 33 connected thereto is completely exposed outside. At this time, when the guiding component 4 acts on the nozzle part 340, the filling position of the nozzle part 340 can be freely adjusted. When traditional fixed-point filling needs to be realized, the guiding component 4 can be slid to move the nozzle part 340 thereon, so that the second rigid pipe 32 and the corrugated hose 33 both move inside the connection cavity 342. Through the rigid connection between the tail part 341 and the first rigid pipe 31, it is ensured that the center of the nozzle part 340 and the filling pipe 12 are on the same straight line, meeting the requirement that the operator can rotate adaptively according to different situations during the tunnel repair process, and increasing the applicable range of the equipment;

[0045] The guiding component 4 includes a grip 41 connected to the surface of the tail part 341, a support rod 42 connected to the middle of the grip 41, and a universal ball 43 connected to one end of the support rod 42;

[0046] Among them, the support rod 42 is movably connected through the universal ball 43 to a telescopic member connected to the gun base 2;

[0047] The telescopic member includes a universal seat 44 that movably wraps the surface of the universal ball 43, an inner rod 45 connected to the surface of the universal seat 44, and an outer rod 46 that is slidably sleeved on the surface of the inner rod 45;

[0048] One end of the outer rod 46 is fixedly connected to the gun seat 2. The universal ball 43 can rotate inside the universal seat 44 without falling off. When the tunnel repair equipment needs to perform repair operations at a fixed point, the moving grip 41 is moved to drive the mouth part 340 to move the second rigid pipe 32 and the corrugated hose 33 inside the connection cavity 342. Through the rigid connection between the first rigid pipe 31 and the tail part 341, fixed-point filling of the mouth part 340 is formed.

[0049] In special cases where the filling pipe 12 needs to be fixed at a point to perform universal adjustment filling of the mouth part 340, the moving grip 41 is moved to expose the second rigid pipe 32 and the corrugated hose 33 inside the connection cavity 342 to the outside. At this time, relative movement can occur between the second rigid pipe 32 and the first rigid pipe 31, and the mouth part 340 can be controlled by the grip 41 to perform filling in different areas to meet the actual repair needs inside the tunnel, increasing the scope of use of the equipment.

[0050] A piston handle 120 is provided inside the filling pipe 12. One end of the piston handle 120 penetrates through the gun seat 2 and is fixed with a push handle 121. The material to be filled is injected into the filling pipe 12, and then the piston handle 120 is moved inside the filling pipe 12. By pushing the push handle 121 from the outside, the piston handle 120 is pushed to move inside the filling pipe 12, so that the material inside it flows out through the delivery pipe 13 and the filling assembly 3, realizing the filling of the repair area inside the tunnel.

[0051] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered within the scope of the claims of the present invention.
