Description

Technical Field

[0001] This utility model relates to the field of grouting technology, and in particular to a tunnel fissure grouting device. Background Technology

[0002] Grouting is a technique used in underground engineering to seal cracks, holes, or pipes, and is widely used in tunnels, foundation pits, coal mines, and other engineering fields. In tunnel fissure grouting, grouting holes are drilled at the grouting location, grouting pipes are inserted, and connected to grouting hoses. Since the grouting holes may be located on the sides or at the tunnel arch, scaffolding or supports are needed to support the grouting hoses during actual operation to prevent them from falling. However, the erection and dismantling of these scaffolding or supports are complex, and the dimensions and shapes of the scaffolding or supports corresponding to the tunnel's inner walls and arch are completely different, making the erection process cumbersome and inefficient.

[0003] Therefore, there is an urgent need to develop a tunnel fissure grouting device that is simple in structure and reliable in grouting. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a tunnel fissure grouting device. The technical solution adopted by this utility model is as follows:

[0005] A tunnel fissure grouting device, placed inside a tunnel and receiving grouting fluid, includes a grouting pump assembly, a grouting delivery pipe support assembly, and a grouting pipe arranged sequentially along the grouting direction. The grouting pump assembly receives the grouting fluid. The grouting pump assembly includes a first traveling trolley, a grouting pump mounted on the first traveling trolley, a receiving hopper connected to the grouting pump and receiving the grouting fluid, a grouting motor connected to the grouting pump, and a grouting delivery pipe connecting the grouting pump and the grouting pipe. The grouting delivery pipe support assembly clamps and supports the grouting delivery pipe.

[0006] The grouting delivery pipe support assembly includes a trailer vehicle, a lower telescopic support frame assembly fixed on the trailer vehicle, a multi-position electric rotary table mounted on the lower telescopic support frame assembly, and an upper telescopic support frame assembly mounted on the multi-position electric rotary table. The multi-position electric rotary table drives the grouting delivery pipe or grouting pipe toward the inner wall or arch of the tunnel. The front end of the upper telescopic support frame assembly clamps the grouting delivery pipe or grouting pipe. The lower telescopic support frame assembly and the upper telescopic support frame assembly drive the grouting delivery pipe closer to the inner wall or arch of the tunnel.

[0007] Furthermore, several telescopic support feet are provided on both sides of the trailer vehicle.

[0008] Furthermore, the lower telescopic support frame assembly includes a lower rectangular base frame mounted on the trailer, a lower mounting plate mounted on the lower rectangular base frame, two first longitudinal slide rods fixed to the lower mounting plate, a first upper crossbeam mounted on the top of the two first longitudinal slide rods, a first lead screw rotatably sleeved on the first upper crossbeam and the lower mounting plate and positioned between the two first longitudinal slide rods, several first slider seats slidably sleeved on the first longitudinal slide rods, a first lead screw nut seat threadedly connected to the first lead screw, a first longitudinal sliding plate fixedly connected to the first slider seat and the first lead screw nut seat, and a first lead screw motor mounted on the lower rectangular base frame and connected to the first lead screw; the first lead screw motor drives the first longitudinal sliding plate to slide along the direction of the first longitudinal slide rod; the multi-station electric rotary disk is fixed on the first longitudinal sliding plate.

[0009] Furthermore, two reinforcing longitudinal beams are provided between the lower rectangular underframe and the trailer vehicle.

[0033] like Figures 1 to 8 As shown, this embodiment provides a tunnel fissure grouting device, which is placed inside the tunnel and receives grouting fluid. Grouting holes are opened in the area to be grouted, and grouting pipes (or specific grouting anchors) are inserted. Here, taking a grouting anchor as an example, it is fixedly installed inside the grouting hole. Here, the grouting delivery pipe 15 is clamped by the grouting delivery pipe support assembly 2, and its orientation towards the grouting anchor is adjusted to allow for grouting connection.

[0034] Here, the tunnel fissure grouting device includes a grouting pump assembly 1, a grouting delivery pipe support assembly 2, and a grouting pipe 3 (grouting anchor) arranged sequentially along the grouting direction. The grouting pump assembly 1 receives grouting fluid from the grouting tanker. The grouting pump assembly 1 includes a first traveling trolley 11, a grouting pump 13 mounted on the first traveling trolley 11, a receiving hopper 12 connected to the grouting pump 13 and receiving the grouting fluid, a grouting motor 14 connected to the grouting pump 13, and a grouting delivery pipe 15 connecting the grouting pump 13 and the grouting pipe 3. The grouting delivery pipe support assembly 2 clamps and supports the grouting delivery pipe 15.

[0035] In this embodiment, the grouting delivery pipe support assembly 2 includes a trailer vehicle 21, several telescopic support feet 22 respectively disposed on both sides of the trailer vehicle 21, a lower telescopic support frame assembly 23 fixed on the trailer vehicle 21, a multi-position electric rotary table 24 disposed on the lower telescopic support frame assembly 23, and an upper telescopic support frame assembly 25 disposed on the multi-position electric rotary table 24. The multi-position electric rotary table 24 drives the grouting delivery pipe 15 towards the inner wall or arch of the tunnel, i.e., towards the location of the grouting anchor rod, which may be located on the inner wall or the arch of the tunnel. Here, the front end of the upper telescopic support frame assembly 25 clamps the grouting delivery pipe 15, and the lower telescopic support frame assembly 23 and the upper telescopic support frame assembly 25 drive the grouting delivery pipe 15 closer to the grouting anchor rod for grouting connection. The grouting delivery pipe 15 and the grouting anchor rod are connected using a conventional flange connection.

[0036] In this embodiment, the lower telescopic support frame assembly 23 includes a lower rectangular base frame 2301 mounted on the trailer 21, two reinforcing longitudinal beams 2302 positioned between the lower rectangular base frame 2301 and the trailer 21, a lower mounting plate 2303 mounted on the lower rectangular base frame 2301, two first longitudinal sliding rods 2304 fixed to the lower mounting plate 2303, and a first upper crossbeam 2305 positioned at the top of the two first longitudinal sliding rods 2304. The lower telescopic support frame assembly 23 is rotatably sleeved on the first upper crossbeam 2305 and the lower... A first lead screw 2306 is mounted on the mounting plate 2303 and positioned between two first longitudinal slide bars 2304; several first slider seats 2307 are slidably sleeved on the first longitudinal slide bars 2304; a first lead screw nut seat 2308 is threadedly connected to the first lead screw 2306; a first longitudinal slide plate 2309 is fixedly connected to the first slider seats 2307 and the first lead screw nut seat 2308; and a first lead screw motor 2310 is mounted on the lower rectangular base 2301 and connected to the first lead screw 2306. The first lead screw motor 2310 drives the first longitudinal slide plate 2309 to slide along the direction of the first longitudinal slide bars 2304. Additionally, a multi-station electric rotary disk 24 is fixed to the first longitudinal slide plate 2309 and drives the support plate 2501 to adjust its position. Figure 1 For example, when it is necessary to connect the grouting anchor rods at the top of the tunnel arch, the multi-position electric rotary table 24 is rotated clockwise so that the grouting delivery pipe 15 faces the grouting anchor rod to be connected. Then, the lower telescopic support frame assembly 23 and the telescopic support frame assembly 25 are used to adjust the grouting delivery pipe 15 so that the grouting delivery pipe 15 is close to the grouting anchor rod, and then the connection can be made.

[0037] The telescopic support frame assembly 25 includes a support plate 2501 mounted on a multi-station electric rotary disk 24, a second slider seat 2502 and a second lead screw nut seat 2503 mounted on the support plate 2501, a second slide rod 2504 sleeved on the second slider seat 2502, a second lead screw 2505 threadedly connected to the second lead screw nut seat 2503, a rear linkage frame 2506 mounted at the rear end of the second slide rod 2504, a second lead screw motor 2507 fixed on the rear linkage frame 2506 and connected to the second lead screw 2505, a front crossbeam 2508 mounted at the front end of the second slide rod 2504, and a saddle clamp 2509 mounted on the front crossbeam 2508 and clamping the grouting delivery pipe 15 or the grouting pipe 3. The saddle clamp 2509 includes a lower saddle seat 25091 and a U-shaped frame 25092 fixed on the front crossbeam 2508, an upper saddle seat 25093 disposed inside the U-shaped frame 25092 and opposite to the lower saddle seat 25091, and an adjusting screw 25094 threadedly connected to the U-shaped frame 25092 and connected to the upper saddle seat 25093. Here, the front end of the grouting delivery pipe 15 is placed between the upper saddle seat 25093 and the lower saddle seat 25091. The upper saddle seat 25093 is adjusted using the adjusting screw 25094 so that it moves closer to the lower saddle seat 25091, thus clamping the grouting delivery pipe 15 between the upper saddle seat 25093 and the lower saddle seat 25091.

[0038] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
