Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grouting for tunnel and bridge construction, and more specifically, to a grouting device for tunnel and bridge construction. Background Art
[0002] There are some technical problems in the existing grouting devices used in tunnel and bridge construction. First, the existing discharge port structure design is relatively simple and the size of the discharge port is small, which leads to easy blockage during actual use. The blockage not only affects the continuity of the grouting operation, but may also require shutdown for cleaning, thereby reducing construction efficiency.
[0003] Secondly, the existing grouting devices usually need to frequently connect and release the pipes during the construction process. However, due to the relatively simple structural design in the prior art, it is often impossible to achieve rapid connection and release between the pipes, which results in a long connection and release operation and increases the complexity and labor intensity of the construction.
[0004] In addition, although some existing grouting devices can achieve quick connection of pipes, such quick connection often comes at the expense of the sealing performance of the pipe joints. Insufficient sealing performance of the joints may cause slurry leakage, which not only wastes materials but also may affect the strength and stability of the structure. Utility Model Content

[0032] A threaded sleeve 17 is provided on one side of the guide sleeve 5. The threaded sleeve 17 is detachably mounted on the outside of the connecting sleeve through threads.
[0033] An anti-slip strip 18 is disposed on the outer side of the guide sleeve 5 , and a plurality of anti-slip strips 18 are fixedly connected to the outer side of the guide sleeve 5 .
[0034] In this embodiment, before using the device for grouting operation, it is necessary to first connect the corresponding pipeline and the delivery pipe 11 set on one side of the discharge pipe 3, first push the guide sleeve 5 upward, the setting of the anti-slip strip 18 can increase the friction force of the outer surface of the guide sleeve 5, and then the guide sleeve 5 will cooperate with the fixed plate 14 to squeeze the push spring 12, and at the same time the guide sleeve 5 will drive the guide rod 8 and the guide groove 9 to move.

[0035] See also Figure 1-3 As an implementation method of the dredging device: the dredging device includes a fixed frame 19, a connecting block 20, a movable frame 21, a connecting frame 22, a connecting rod 23 and a sealing block 24. The fixed frame 19 is fixedly installed on the inner side of the base 1, and the movable frame 21 is movably installed on one side of the fixed frame 19. One end of the connecting block 20 is movably connected to the movable frame 21, and the other end of the connecting block 20 is movably connected to the connecting frame 22. The top of the connecting frame 22 is connected to the sealing block 24 through the connecting rod 23.
[0036] A top block 25 is provided in the discharge pipe 3 , and the top block 25 is fixedly connected to the top of the sealing block 24 .
[0037] A slide bar 26 is provided on one side of the fixing frame 19, and the connecting frame 22 and the slide bar 26 are connected in a sliding manner.

[0040] More specifically, when a blockage occurs inside the discharge pipe 3, the motor 27 is turned on. The motor 27 drives the movable frame 21 to rotate after passing through the reduction seat of the reducer 28. Since the two ends of the connecting block 20 are movably connected to the movable frame 21 and the connecting frame 22 respectively, and the slide bar 26 limits the connecting block 20, when the movable frame 21 rotates, it will drive the connecting block 20 to move, and then the connecting block 20 will drive the connecting frame 22 to slide up and down along the slide bar 26, and then the connecting frame 22 will drive the sealing block 24 and the top block 25 to slide up and down in the feed pipe through the connecting rod 23, so that the top block 25 can clear the discharge pipe 3.
[0041] In summary, when the overall equipment is in use or running: before using the equipment for grouting operation, it is necessary to first connect the corresponding pipeline and the conveying pipe 11 set on one side of the discharge pipe 3, first push the guide sleeve 5 upward, the setting of the anti-slip strip 18 can increase the friction force of the outer surface of the guide sleeve 5, and then the guide sleeve 5 will cooperate with the fixed plate 14 to squeeze the push spring 12, and at the same time the guide sleeve 5 will drive the guide rod 8 and the guide groove 9 to move. Due to the special structural design of the guide rod 8 and the guide groove 9, when the guide rod 8 and the guide frame 7 follow the guide sleeve 5 to slide, they will drive the guide frame 7 to move outward, so that the guide frame 7 drives the plug-in rod 10 to move outward. When the push spring 12 is squeezed to the limit, one end of the plug-in rod 10 is pressed against the inner wall of the conveying pipe 11. Flush, then the delivery pipe 11 is fitted onto the outside of the corresponding connecting pipe 4, and then the guide sleeve 5 is loosened, the push spring 12 will push the guide sleeve 5 to reset, and then the guide sleeve 5 will drive the guide rod 8 and the guide groove 9 to reset, so that the plug guide frame 7 and the plug rod 10 are reset, and then one end of the plug rod 10 will be inserted into the plug groove 6 to achieve a quick connection between the connecting pipe 4 and the delivery pipe 11. At this time, the push spring 12 has not been fully reset, and then the push spring 12 will be fully reset and push the guide sleeve 5 against the threaded sleeve 17, so that the plug rod 10 drives the connecting pipe 4 to move inward through the plug groove 6, and then the multiple sealing plates 15 arranged on the outside of the connecting pipe 4 will be engaged with the corresponding sealing grooves 16, thereby ensuring a high degree of sealing at the pipeline connection.
[0042] When the discharge pipe 3 is blocked, the motor 27 is turned on. After passing through the reduction seat of the reducer 28, the motor 27 drives the movable frame 21 to rotate. Since the two ends of the connecting block 20 are movably connected to the movable frame 21 and the connecting frame 22 respectively, and the sliding rod 26 limits the connecting block 20, when the movable frame 21 rotates, it will drive the connecting block 20 to move, and then the connecting block 20 will drive the connecting frame 22 to slide up and down along the sliding rod 26, and then the connecting frame 22 will drive the sealing block 24 and the top block 25 to slide up and down in the feed pipe through the connecting rod 23, so that the top block 25 can clear the discharge pipe 3.
[0043] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
