Abstract
Description
Technical Field
[0001] This utility model relates to the field of road and bridge construction technology, and specifically to a grouting device for road and bridge construction. Background Technology
[0002] Roads and bridges generally consist of several major parts, including roadbed, pavement, bridges, tunnels, and traffic engineering facilities. Grouting in construction engineering involves injecting a solidifiable grout into cracks or pores in rock and soil foundations using appropriate methods, improving their physical and mechanical properties through replacement, filling, and compression. Concrete grouting is required during bridge construction.
[0003] For example, the utility model patent with publication number CN218314328U discloses a concrete grouting device for bridge construction. By setting up a cleaning component, the inner wall of the tank can be easily cleaned with the cooperation of a scraper and multiple sets of water spray heads.
[0004] In the aforementioned patent, although the scraper structure is used to remove slurry from the inner wall of the tank, the scraper is fixed to the mixing device and is in contact with the tank wall for a long time. The scraper is constantly rubbing against the tank wall as the mixing device rotates. Therefore, the wear-resistant scraper will still reduce its durability. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a grouting device for road and bridge construction, so as to solve the technical problem of low durability of the scraper used for scraping grout in the prior art.
[0006] This utility model is achieved through the following technical solution:

An adjusting structure is provided on the rotating disk, and a stirring motor is fixedly mounted on the rotating disk. The output end of the stirring motor is connected to the adjusting structure. A pair of stirring components are provided on the adjusting structure. The stirring components pass through the rotating disk and extend into the grout tank. A scraping component is provided on the stirring components, and the scraping component is in movable contact with the inner wall of the grout tank. A balancing structure is provided on the pair of stirring components and the grout tank.
[0008] Furthermore, the adjusting structure includes a concave box, a bidirectional lead screw is rotatably connected inside the concave box, a pair of slides are threaded onto the bidirectional lead screw, the slides are slidably connected inside the concave box, the concave box is fixedly connected to the top of the rotating disk, and rotating tool heads are fixedly connected to both ends of the bidirectional lead screw.
[0009] Furthermore, a bracket is fixedly connected to the stirring motor and the tank lid, and the output end of the stirring motor is fixedly connected to the concave box via a coupling.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0029] Please see Figure 1-6 This utility model provides a technical solution: a grouting device for road and bridge construction, which is used for municipal road and bridge construction and can be mounted on an existing vehicle body. It includes a grout tank 1 with a columnar and conical structure arranged from top to bottom. The top of the grout tank 1 is fixedly connected to a grout discharge pipe 3, and the top of the grout tank 1 is bolted to a tank cover 2.
[0030] One end of the grout discharge pipe 3 can be connected to a grout pump to extract the grout stored in the grout tank 1. In this way, the grout pump can lead the grout to the bridge construction location. The grout discharge pipe 3 is set in a Y-shaped structure, which can increase the grout throughput. The connection between the tank cover 2 and the grout tank 1 by bolts can easily open the grout tank 1, and at the same time, it is convenient for the structure set on the tank cover 2 to be installed on the grout tank 1.
[0031] In this embodiment: a rotating disk 4 is rotatably connected to the can lid 2, and an adjusting structure 5 is provided on the rotating disk 4. The adjusting structure 5 includes a concave box 51, and a bidirectional lead screw 52 is rotatably connected inside the concave box 51. A pair of slide seats 53 are threadedly connected to the bidirectional lead screw 52. The slide seats 53 are slidably connected inside the concave box 51. The concave box 51 is fixedly connected to the top of the rotating disk 4, and rotating tool heads 11 are fixedly connected to both ends of the bidirectional lead screw 52.
[0032] The rotating disk 4 provides rotational support for the adjustable distance structure 5 on the can lid 2. The slide block 53 is designed with a cross-shaped structure. The concave box 51 is provided with a sliding groove that matches the slide block 53. When the slide block slides inside the sliding groove, the outer surface of the slide block abuts against the inner surface of the sliding groove. This allows the force generated by the slide block abutting against the sliding groove when the bidirectional screw rotates to drive the relative displacement of the slide block. This avoids the slide block being too small or unable to abut against the sliding groove, which would cause the slide block to rotate with the bidirectional screw and thus prevent relative displacement. In this way, the bidirectional screw 52 can ensure the stability of the sliding of the slide block 53 while ensuring the strength of the force. When the adjustable distance structure 5 is in use, the rotating tool head 11 is controlled by a hardware tool. The rotation of the bidirectional screw 52 can drive the pair of slide blocks 53 on it to slide closer or further apart in the concave box 51.
[0033] In this embodiment: a stirring motor 6 is fixedly mounted on the rotating disk 4, the output end of the stirring motor 6 is connected to the adjustable structure 5, a bracket 12 is fixedly connected to the stirring motor 6 and the tank cover 2, and the output end of the stirring motor 6 is fixedly connected to the concave box 51 through a coupling.
[0034] The stirring motor 6 is model Y180M-4 with a power of 18.5kW. By starting the stirring motor 6, it can drive the adjusting structure 5 and the rotating disk 4 to rotate, so that the position of the adjusting structure 5 can transmit power to the stirring facilities in the slurry tank 1.
[0035] In this embodiment: A pair of stirring components 7 are provided on the adjusting structure 5. The stirring components 7 pass through the rotating disk 4 and extend into the slurry tank 1. The stirring components 7 include a transmission rod 71, which is fixedly connected to the slide 53. The outer surface of the transmission rod 71 is fixedly connected to the stirring blade 72. A transverse groove is provided on the rotating disk 4. The transmission rod 71 passes through the transverse groove on the rotating disk 4 and extends into the slurry tank 1.
[0036] Since the transmission rod 71 passes through the transverse groove and is connected to the slide 53, when a pair of slides 53 move relative to each other through the bidirectional screw 52, they can drive a pair of transmission rods 71 to adjust the distance between them. The stirring power provided by the stirring motor 6 can drive the stirring blades 72 on the transmission rod 71 to stir the slurry in the slurry tank 1.
[0037] In this embodiment: A scraping assembly 8 is provided on the stirring assembly 7. The scraping assembly 8 is in contact with the inner wall of the slurry tank 1. The scraping assembly 8 includes a first wear-resistant scraper 81 and a second wear-resistant scraper 82. The first wear-resistant scraper 81 and the second wear-resistant scraper 82 are in contact with the cylindrical inner wall and the conical inner wall of the slurry tank 1, respectively. A fixing rod 13 is fixedly connected to both the first wear-resistant scraper 81 and the second wear-resistant scraper 82. The fixing rod 13 is fixedly connected to the transmission rod 71.
[0038] Since the first wear-resistant scraper 81 and the second wear-resistant scraper 82 are fixed to the transmission rod 71 by the corresponding fixing rod 13, when the transmission rod 71 rotates, it can drive the first wear-resistant scraper 81 and the second wear-resistant scraper 82 to rotate in a ring inside the slurry tank 1. When the first wear-resistant scraper 81 and the second wear-resistant scraper 82 come into contact with the inner wall of the slurry tank 1, the first wear-resistant scraper 81 and the second wear-resistant scraper 82 can scrape off the slurry on the inner wall of the slurry tank 1, which makes it convenient to clean the residual slurry.
[0039] It is worth noting that, since the spacing of the pair of transmission rods 71 can be adjusted, when the slurry tank 1 only needs to be stirred and not cleaned, by controlling the pair of transmission rods 71 to be relatively close, the first wear-resistant scraper 81 and the second wear-resistant scraper 82 can be kept away from the inner wall of the slurry tank 1. This reduces the involvement of the first wear-resistant scraper 81 and the second wear-resistant scraper 82 with the slurry tank 1, thus avoiding the first wear-resistant scraper 81 and the second wear-resistant scraper 82 from rubbing against the slurry tank 1 in real time during the stirring action, which would accelerate wear.
[0040] In this embodiment: a pair of stirring components 7 and a slurry tank 1 are provided with a balancing structure 9. The balancing structure 9 includes a rotating rod 91, which is rotatably connected to the bottom of the slurry tank 1. A support 92 is fixedly connected to the top of the rotating rod 91. A pair of guide grooves 93 are provided on the support 92. A guide block 94 is movably connected in the guide groove 93. The guide block 94 is fixedly connected to the bottom of the transmission rod 71. The cross-section of the guide block 94 is a right-angled trapezoidal structure.
[0041] The guide groove 93 is adapted to the guide block 94, which can prevent the slurry from affecting the movement of the guide block 94 on the guide groove 93. When the balance structure 9 is in use, since the mixing assembly 7 only has the adjusting structure 5 to provide a connection fulcrum for it during the mixing process, the transmission rod 71 can only rotate in one direction when it rotates. The right-angled trapezoidal structure of the guide block 94 allows its inclined surface to be supported on the guide groove 93, which can meet the requirement of the bottom of the transmission rod 71 to obtain a fulcrum. At the same time, the support 92 will also rotate with the rotation of the transmission rod 71, which can prevent the mixing assembly 7 from deforming due to force defects during rotation. Since the pair of transmission rods 71 need to be adjusted in distance, the guide block 94 can slide on the guide groove 93 to meet the movement requirements of the distance adjustment, so that the mixing assembly 7 can be more stable when rotating.
[0042] In this embodiment, the top of the can lid 2 is fixedly connected to a connecting pipe 10.
[0043] The connection pipe 10 allows for easy introduction of mixed slurry for municipal road and bridge construction into the slurry tank 1. In addition, when the slurry tank 1 needs to be cleaned, a water pipe can be easily inserted into the connection pipe 10 to flush the residual slurry from the inner wall of the slurry tank 1. Combined with the scraper assembly 8 installed inside the slurry tank 1, this makes it easy to clean the slurry tank 1.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
