DETAILED DESCRIPTION

[0021] The technical scheme of the present application will be further described in detail below in combination with specific embodiments.

[0022] Example 1

[0023] Please refer to Figures 1-5 A kind of municipal road bridge construction and is used grouting device, including frame 1 and the jar body 2 and pump body 3 of installation on frame 1, the top surface of jar body 2 is equipped with feed pipe 4, the output end of pump body 3 is equipped with grouting nozzle 5 by grouting pipe, still include stirring assembly and vibration assembly;

[0024] The stirring assembly comprises a driving shaft 6 rotatably arranged in the tank body 2 and a plurality of stirring rods 7 mounted on the driving shaft 6, and the driving shaft 6 is driven by a motor 8 arranged on the tank body 2;

[0025] The vibration assembly comprises a frame 9 fixedly arranged on the side of the tank body 2, a pair of movable columns 10 movably arranged in the frame 9, and a driving unit for driving the movable columns 10 to move upward intermittently. The movable columns 10 are movably arranged in the frame 9 by springs 12, and the bottom ends of the movable columns 10 are fixedly provided with knocking hammers 11. By arranging the stirring assembly and the vibration assembly, when the slurry is injected into the gap or the aperture, the stirring assembly can stir the slurry in the tank body 2, so as to avoid the phenomenon of slurry coagulation. In the process of driving the two movable columns 10 to move upward intermittently, the knocking hammers 11 at the bottom ends of the movable columns 10 can knock the bottom surfaces of the two sides of the gap or the aperture by cooperating with the springs 12, so as to make the ground vibrate. Under the action of vibration, the slurry injected into the gap or the aperture accelerates the flow of the slurry, so that the slurry can fill every corner in the gap or the aperture, avoiding the phenomenon of filling dead corners, and improving the quality of grouting.

[0026] The driving unit comprises shafts 13, a first gear set 14, half gears 15 and a movable rod 16. The two shafts 13 are drivingly connected by the first gear set 14, and the two shafts 13 are symmetrically provided with the half gears 15. One end of the movable rod 16 is fixedly arranged on the movable column 10, and the other end penetrates through the top surface of the frame 9. The side surface of the movable rod 16 is further provided with a plurality of teeth 17 meshing with the half gears 15. In the process of being driven to rotate, one of the shafts 13 drives the other shaft 13 to rotate by the transmission of the first gear set 14. When the half gears 15 on the shafts 13 mesh with the teeth 17 on the movable rod 16, the movable rod 16 can be driven to move upward together with the movable column 10. When the meshing disappears, the movable column 10 is reset under the action of the spring 12, and the knocking hammer 11 knocks the ground, which can be repeated to vibrate the ground around the gap or the aperture.

[0027] Preferably, a first transmission shaft 18 is rotatably arranged in the tank body 2 near one side of the frame 9. One end of a second transmission shaft 23 is fixedly provided with a first bevel gear 19, and the other end is drivingly connected with one of the shafts 13 through a second gear set 21. The driving shaft 6 is provided with a second bevel gear 20 meshing with the first bevel gear 19. The arrangement of the first transmission shaft 18, the first bevel gear 19, the second bevel gear 20 and the second gear set 21 can drive the shaft 13 to rotate without additional driving elements, which reduces the power consumption of the device during operation and has the advantages of energy saving and emission reduction.

[0028] Example 2

[0029] The embodiment is improved on the basis of embodiment 1, specifically:

[0030] Please refer to Figure 2 and Figure 5 , the feeding pipe 4 is also provided with a crushing mechanism, which includes a pair of crushing rollers 22 arranged side by side in the feeding pipe 4, and the two crushing rollers 22 are connected through a third gear set. The crushing mechanism can crush the agglomerated material in the grouting material during the process of adding the grouting material from the feeding pipe 4 to the tank body 2. The crushed material is easier to mix uniformly, and will not cause the blockage of the grouting nozzle 5.

[0031] Preferably, the end of one of the crushing rollers 22 is also provided with a second transmission shaft 23, which is rotatably arranged in the tank body 2, and the end of the second transmission shaft 23 is provided with a third bevel gear 24 engaged with the second bevel gear 20. The second transmission shaft 23 and the third bevel gear 24 do not need to be driven by additional driving elements to operate the crushing mechanism, further reducing the power consumption of the device during operation.

[0032] In addition, the top surface of the tank body 2 is also fixedly provided with a housing 25, and the first gear 26 and the second gear 27 are rotatably arranged in the housing 25. The diameter of the first gear 26 is smaller than that of the second gear 27, and the first gear 26 is connected to the output end of the motor 8. The second gear 27 is coaxially fixedly installed on the driving shaft 6. The first gear 26 and the second gear 27 drive the rotation of the large gear through the small gear, which increases the torque and saves labor, reduces the load of the motor 8, and prolongs the service life of the motor 8.

[0033] Working principle and operation process: when the gap or pore is grouted and filled, first push the frame 1 to the gap or pore position, and ensure that the two knocking hammers 11 are on both sides of the gap or pore. At the same time of opening the pump body 3 to inject grouting material into the gap or pore, the motor 8 is started, and the motor 8 drives the driving shaft 6 to rotate, which can stir the grouting material in the tank body 2 to avoid the phenomenon of grouting material condensation. In this process, through the engagement transmission of the first transmission shaft 18, the first bevel gear 19, the second bevel gear 20 and the second gear set 21, one of the rotating shafts 13 can be driven to rotate, and through the transmission of the first gear set 14, the other rotating shaft 13 rotates relatively. When the half gear 15 installed on the rotating shaft 13 is engaged with the tooth 17 on the movable rod 16, the movable rod 16 can be driven to move upward together with the movable column 10. When the engagement disappears, the movable column 10 is reset under the action of the spring 12, and drives the knocking hammer 11 to knock the ground. Through repeated operations, the vibration of the ground around the gap or pore can be realized. In addition, under the transmission of the second transmission shaft 23 and the third bevel gear, the crushing mechanism can crush the agglomerated material in the grouting material. The crushed material is easier to mix uniformly, and will not cause the blockage of the nozzle.

[0034] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments should, therefore, be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalents of the claims are therefore intended to be embraced therein.
