Description

Technical Field

[0001] The utility model relates to the field of tunnel repair equipment, in particular to a tunnel wall crack filling device which is convenient to use. Background Technique

[0002] Tunnel pipes usually refer to the wall structures that form the inner perimeter of a tunnel. The main functions of the tunnel wall include supporting the rock and soil inside the tunnel, preventing collapse and deformation, and also playing roles such as waterproofing, sound insulation, and fire prevention. After the inner wall of the tunnel is built, due to various factors, wall cracks may occur and need to be repaired in a timely manner. Conventional repair equipment uses a grouting machine to fill the leaking and cracked areas.

[0003] After the grouting machine is used, in order to avoid blockage of the pipeline and the grouting machine, a cleaning agent needs to be used to clean the grouting machine and the pipeline. The existing cleaning method is to inject the cleaning liquid into the storage barrel, and then use the grouting machine to pump the cleaning liquid in the storage barrel into the grouting pipe. The other end of the grouting pipe is placed in the cleaning barrel, and the cleaning liquid in the storage barrel is circulated to achieve the purpose of cleaning. However, this method has the following defects when in use: when the grouting pipe is placed in the cleaning barrel, the cleaning liquid sprayed by the grouting pipe is prone to splashing, and the barrel wall of the storage barrel cannot be evenly cleaned, which is prone to residual slurry on the barrel wall. In view of the above defects, for this reason, we propose a tunnel wall crack filling device which is convenient to use. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a tunnel wall crack filling device which is convenient to use.

[0007] A feeding structure, the feeding structure includes a suction shell fixedly installed on the lower surface of the chassis, a diaphragm fixedly installed on the inner wall of the suction shell, and a feeding pipe, a discharging pipe and an air inlet pipe respectively fixedly installed on the right end of the suction shell;

[0008] A stirring structure, the stirring structure includes a protective cover, a connecting pipe rotatably installed at the lower end of the protective cover, and a stirring blade fixedly installed on the surface of the connecting pipe;

[0009] A cleaning structure, the cleaning structure is arranged on the surface of the connecting pipe and is used for cleaning the storage barrel, and it includes water outlet holes equidistantly opened on the surface of the connecting pipe, and an adapter pipe rotatably installed at the upper end of the connecting pipe;

[0016] Preferably, the other end of the feed pipe communicates with the interior of the storage barrel.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By arranging a cleaning structure and a driving structure, connect the external grouting pipe to the discharge pipe, then cover the protective cover on the storage barrel. At this time, the cross-shaped limiting block will be inserted into the limiting groove. When the driving structure drives the crank to rotate, the crank will drive the connecting shaft and the connecting pipe to rotate synchronously. At the same time, the rotation of the crank will also drive the diaphragm to move left and right. The left and right movement of the diaphragm will suck the cleaning liquid in the storage barrel into the suction shell and discharge it along the discharge pipe. Then insert the external grouting pipe into the connecting pipe, so that the feeding structure can pump the cleaning liquid in the storage barrel into the external grouting pipe and spray it into the storage barrel through the external grouting pipe for circulation. At the same time, the driving structure will synchronously drive the connecting pipe to rotate, so that the cleaning liquid sprayed by the external grouting pipe is ejected along the water outlet holes. The rotating connecting pipe cooperates with the water outlet holes to evenly eject the cleaning liquid to impact the storage barrel, so as to evenly wash the slurry on the inner wall of the storage barrel, avoid the problem of slurry residue, and the protective cover can prevent the cleaning liquid from splashing.

[0019] 2. By setting up a feeding structure, during grouting, the stop valve on the surface of the feed pipe is opened, and the stop valve on the surface of the air inlet pipe is closed. When the crank rotates, the crank will pull the connecting rod to drive the diaphragm to move back and forth left and right. When the diaphragm moves to the left, suction will be generated in the suction shell, so that the slurry in the storage barrel can be sucked into the suction shell. When the diaphragm moves to the right, the slurry in the suction shell will be discharged into the external grouting pipe along the discharge pipe, so that grouting operation can be carried out, and the stop valve on the surface of the air inlet pipe is opened, and the stop valve on the surface of the feed pipe is closed. Then the stirring structure is installed in the storage barrel. When the crank rotates, the crank will drive the stirring structure to rotate, so that the slurry can be stirred to make it uniform. At the same time, when the diaphragm moves to the left, the air inlet pipe can suck external air into the suction shell to prevent the slurry in the storage barrel that is not stirred uniformly from entering the suction shell.

[0028] See also Figure 1, the base includes a chassis 1 and a slurry storage cylinder 2 fixedly installed on the upper surface of the chassis 1. The slurry storage cylinder 2 can store slurry.

[0029] Refer to Figure 2 , the feeding structure includes a suction housing 3 fixedly installed on the lower surface of the chassis 1, a diaphragm 4 fixedly installed on the inner wall of the suction housing 3, and a feed pipe 5, a discharge pipe 6, and an air inlet pipe 7 respectively fixedly installed at the right end of the suction housing 3. The other end of the feed pipe 5 communicates with the interior of the slurry storage cylinder 2. Shut-off valves 17 are provided on the surfaces of both the feed pipe 5 and the air inlet pipe 7. Check valves 21 are provided on the surfaces of the feed pipe 5, the air inlet pipe 7, and the discharge pipe 6. The check valve 21 on the surface of the feed pipe 5 can prevent the slurry in the suction housing 3 from entering the slurry storage cylinder 2. The check valve 21 on the surface of the discharge pipe 6 can prevent the slurry in the discharge pipe 6 from flowing back into the suction housing 3. The check valve 21 on the surface of the air inlet pipe 7 can prevent the air in the suction housing 3 from being discharged into the air inlet pipe 7.

[0030] Refer to Figure 1 and Figure 4 , the stirring structure includes a protective cover 18, a connecting pipe 8 rotatably installed at the lower end of the protective cover 18, and a stirring blade 9 fixedly installed on the surface of the connecting pipe 8. External threads are provided on the surface of the slurry storage cylinder 2, and internal threads adapted to the external threads are provided on the inner wall of the protective cover 18. The protective cover 18 can be threadedly connected to the slurry storage cylinder 2 to block the upper opening of the slurry storage cylinder 2.

[0031] Refer to Figure 3 , the driving structure includes a support frame 10 fixedly installed on the lower surface of the chassis 1, a motor 11 fixedly installed on the inner wall of the support frame 10, a crank 12 fixedly installed on the output end of the motor 11, a connecting rod 13 hinged to the inner wall of the crank 12, and a connecting shaft 14 fixedly installed at the upper end of the crank 12. One end of the connecting rod 13 away from the crank 12 is hinged to the left end of the diaphragm 4. The driving motor 11 can drive the crank 12 to rotate. When the crank 12 rotates, it will drive the connecting rod 13 to pull the diaphragm 4 to move left and right, and at the same time drive the connecting shaft 14 to rotate.

[0032] During grouting, first connect the external grouting pipe to the discharge pipe 6, then open the shut-off valve 17 on the surface of the feed pipe 5 and close the shut-off valve 17 on the surface of the air inlet pipe 7. When the crank 12 rotates, at this time the crank 12 will pull the connecting rod 13 to drive the diaphragm 4 to reciprocate left and right. When the diaphragm 4 moves to the left, at this time a suction force will be generated in the suction housing 3, so that the slurry in the slurry storage cylinder 2 can be sucked into the suction housing 3. When the diaphragm 4 moves to the right, at this time the slurry in the suction housing 3 will be discharged into the external grouting pipe along the discharge pipe 6, so that the grouting operation can be carried out.

[0033] Refer to Figure 1 and Figure 4, a cleaning structure is arranged on the surface of the connecting pipe 8 for cleaning the material storage cylinder 2, which includes water outlet holes 19 equidistantly opened on the surface of the connecting pipe 8, and a connecting pipe 20 rotatably installed at the upper end of the connecting pipe 8, and the external grouting pipe is allowed to be inserted into the connecting pipe 20.

And a limiting groove adapted to the cross-shaped limiting block 16 is opened at the bottom of the sleeve 15. When the protective cover 18 is covered on the material storage cylinder 2, at this time, the cross-shaped limiting block 16 will be inserted into the limiting groove, so that the connecting shaft 14 and the sleeve 15 can be assembled into one body.

[0035] When the driving structure drives the crank 12 to rotate, at this time, the crank 12 will drive the connecting shaft 14 and the connecting pipe 8 to rotate synchronously. At the same time, the rotation of the crank 12 will also drive the diaphragm 4 to move left and right. The left and right movement of the diaphragm 4 will suck the cleaning liquid in the material storage cylinder 2 into the suction shell 3 and discharge it along the discharge pipe 6. Then, the external grouting pipe is inserted into the connecting pipe 20, so that the cleaning liquid in the material storage cylinder 2 can be pumped into the external grouting pipe by the feeding structure and sprayed into the material storage cylinder 2 for circulation by the external grouting pipe. At the same time, the driving structure will synchronously drive the connecting pipe 8 to rotate, so that the cleaning liquid sprayed by the external grouting pipe is sprayed out along the water outlet holes 19. The rotating connecting pipe 8 is used in cooperation with the water outlet holes 19 to evenly spray the cleaning liquid to impact the material storage cylinder 2, so that the slurry on the inner wall of the material storage cylinder 2 can be evenly washed, avoiding the problem of slurry residue, and the protective cover 18 can prevent the cleaning liquid from splashing.

[0036] Open the stop valve 17 on the surface of the air inlet pipe 7 and close the stop valve 17 on the surface of the feed pipe 5. Then, install the stirring structure in the material storage cylinder 2. When the crank 12 rotates, the crank 12 will drive the stirring structure to rotate, so that the slurry can be stirred to make it uniform. At the same time, when the diaphragm 4 moves to the left, the air inlet pipe 7 can suck external air into the suction shell 3 to prevent the slurry in the material storage cylinder 2 that has not been evenly stirred from entering the suction shell 3.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered within the protection scope of the present invention.
