Description

Technical Field

[0001] The utility model relates to the field of grouting reinforcement, in particular to a grouting reinforcement device for a highway concrete bridge pavement structure. Background Technique

[0002] During the construction of road bridges, there will be cavities inside the bridge. In order to prevent the risk of the bearing capacity of the beam body from decreasing due to the cavities, it is necessary to seal the cavities inside the beam body. Therefore, the staff use a grouting reinforcement device to drill holes in the bridge and then grout concrete from the drilled holes to achieve the reinforcement of the bridge.

[0003] Chinese Patent No. CN202322727151.4 discloses a grouting reinforcement device, including a bottom plate, a mud tank and a grouting pump. The mud tank is fixedly installed at the top end of the bottom plate. A stirring component is installed at the top end of the mud tank. A feed pipe is fixedly installed at the top end of the surface of the mud tank. A grouting hose is fixedly installed at the bottom end of the surface of the mud tank. The output end of the grouting pump is installed with a slurry outlet pipe. The top end of the slurry outlet pipe is fixedly installed with a first motor. The output end of the first motor is installed with a fixing frame. Four corners of the bottom end of the fixing frame are fixedly installed with fixing rods. A scraping strip is fixedly installed on the side surface of the fixing rod. A bearing is installed at the intersection of the fixing frame and the slurry outlet pipe.

[0004] As can be seen from the above, through the settings of the scraping strip, the fixing frame and the first motor, after the grouting reinforcement device is used, the first motor can drive the scraping strip to move along the inner wall of the slurry outlet pipe, so that the slurry attached to the inner wall of the slurry outlet pipe can be scraped clean in time, avoiding the phenomenon that the slurry solidifies and accumulates on the inner wall of the slurry outlet pipe due to long-term attachment, resulting in the blockage of the slurry outlet pipe. However, this case still has the following deficiencies: when grouting the highway concrete, the slurry needs to be evenly laid on the road surface. During the work, due to pipeline or distance restrictions, the whole needs to be moved to ensure the full coverage of the road surface by the slurry. Moving the whole consumes too much human resources, and at the same time, the work efficiency will be reduced.

[0005] Therefore, a grouting reinforcement device for a highway concrete bridge pavement structure is proposed for the above problems. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] Please refer to Figures 1 - 5 As shown, a grouting reinforcement device for a highway concrete bridge pavement structure includes a body 1 and a movable adjustment device 2; a servo motor 21 is installed on the movable adjustment device 2, a transmission wheel 22 is fixedly installed at the output end of the servo motor 21, a transmission belt 23 is connected around the transmission wheel 22, the other side of the transmission belt 23 is connected to an output wheel 24, and a threaded shaft 26 penetrates and is fixedly installed on one side of the output wheel 24;

[0024] During operation, through the installation of the servo motor 21, power is generated during operation to rotate the transmission wheel 22. Thus, the transmission wheel 22 drives the output wheel 24 and the threaded shaft 26 through the transmission belt 23 accordingly.

[0025] Furthermore, a slurry storage tank 11 is installed on the main body 1. A fixing frame 12 is fixedly installed at the bottom of the slurry storage tank 11. A moving wheel 13 is fixedly installed at the bottom of the fixing frame 12. A support rod 14 is fixedly installed on one side of the fixing frame 12;

[0026] During operation, the slurry storage tank 11 stores the slurry. The fixing frame 12 ensures the bearing of the top components. The installation of the moving wheels 13 facilitates the overall movement and is conducive to the continuous advancement during the grouting operation.

[0027] Furthermore, several buckles 15 are fixedly installed on one side of the slurry storage tank 11. A tank cover 16 is fixedly installed on one side of the slurry storage tank 11 through the buckles 15;

[0028] During operation, by separating the slurry storage tank 11 from the tank cover 16, it is convenient to clean the inside of the slurry storage tank 11 after the work is completed, preventing the slurry from solidifying inside the slurry storage tank 11 and affecting subsequent grouting operations.

[0029] Furthermore, a bearing block 25 is fixedly installed at the bottom of the servo motor 21. A threaded shaft 26 is movably installed on one side of the bearing block 25. One end of the threaded shaft 26 penetrates and is threadedly connected to a threaded sleeve 27. A connecting seat 28 is fixedly installed on one side of the threaded sleeve 27 located at the limiting plate 35;

[0030] During operation, the bearing block 25 positions and bears the servo motor 21 and the threaded shaft 26. The threaded shaft 26 rotates and mates with the threaded sleeve 27 in a threaded manner, causing the threaded sleeve 27 to linearly move on the threaded shaft 26.

[0031] Furthermore, a limiting plate 35 is movably installed between the threaded sleeve 27 and the connecting seat 28. Bearing blocks 25 are fixedly installed at both ends of the limiting plate 35. A connecting rod 29 is fixedly installed on one side of the connecting seat 28;

[0032] During operation, when the threaded sleeve 27 moves, it drives the connecting rod 29 to move synchronously through the fixation with the connecting seat 28. The installation of the limiting plate 35 limits the threaded sleeve 27 to prevent the connecting seat 28 from shaking up and down when the threaded sleeve 27 is driven.

[0033] Furthermore, an output pipe 34 is fixedly installed at the bottom of the connecting rod 29. One end of the output pipe 34 is fixedly installed with an input pipe 31. The other end of the input pipe 31 is fixedly installed with a pump 32. One side of the pump 32 is fixedly installed with a suction pipe 33. One side of the suction pipe 33 penetrates and is fixedly installed with a tank cover 16.

[0034] During operation, the pump 32 is driven to suck the slurry inside the slurry storage tank 11 through the suction pipe 33, and the slurry flows outwards through the output pipe 34 under the guidance of the pump 32 and the input pipe 31.

[0035] Working principle: The pump 32 is driven to extract the slurry inside the slurry storage tank 11 through the suction pipe 33, and the pump 32 transports the slurry to the output pipe 34 through the input pipe 31 for discharging outwards. When the position of the discharged slurry needs to be adjusted, the servo motor 21 is driven to make the driving wheel 22 at the output end rotate, and the output wheel 24 is driven by the transmission belt 23. Under the linkage of the output wheel 24, the threaded shaft 26 rotates on the bearing block 25. When the threaded shaft 26 works, its rotational motion is converted into the linear motion of the threaded sleeve 27 through thread engagement, and the threaded sleeve 27 drives the connecting seat 28 and the connecting rod 29 on one side to move synchronously, so as to adjust the position where the output pipe 34 discharges the slurry.

[0036] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
