[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a grouting device, including: a main support plate 1;

[0029] Two support legs 2 are welded to the left and right sides of the bottom of the main support plate 1. The main support plate 1 is used to provide sliding support for the first support rod 5 and the second support rod 7, and to provide rotational support for the lead screw 3. The support legs 2 are used to support the main support plate 1. A lead screw 3 is rotatably installed on the rear side of the main support plate 1. When the lead screw 3 rotates, it can drive the first support rod 5 and the second support rod 7 to slide left and right under the support of the main support plate 1, thus allowing the position of the first fixing frame 6 and the second fixing frame 8 to be adjusted. A crank 4 is provided at the right end of the lead screw 3, which can be used to rotate the lead screw 3 during use. A first support rod 5 is slidably installed on the front side of the main support plate 1. The first support rod 5 is used to support the first fixing frame 6. A first fixing frame 6 is welded to the front end of rod 5. The first fixing frame 6 cooperates with the second fixing frame 8 to clamp and fix the grouting device body 9, and can clamp grouting device bodies 9 of different outer diameters. A second support rod 7 is also slidably installed on the front side of the main support plate 1. The second support rod 7 is used to support the second fixing frame 8. A second fixing frame 8 is welded to the front end of the second support rod 7. The second fixing frame 8 cooperates with the first fixing frame 6 to clamp and fix the grouting device body 9, and can clamp grouting device bodies 9 of different outer diameters. A grouting device body 9 is installed between the first fixing frame 6 and the second fixing frame 8. The grouting device body 9 is used to grout the road surface and bridge deck.

[0030] In this embodiment of the disclosure, such as Figure 3 , Figure 5 and Figure 6As shown, the thread on the outer side of the lead screw 3 is divided into two sections, and the threads on the left and right sides are symmetrical. The rear ends of the first support rod 5 and the second support rod 7 are each provided with a threaded hole corresponding to the thread on the outer side of the lead screw 3. When the lead screw 3 rotates, it can drive the first support rod 5 and the second support rod 7 to slide synchronously in opposite directions under the support of the main support plate 1. Therefore, the distance between the first fixing frame 6 and the second fixing frame 8 can be increased or decreased, thereby enabling the grouting device body 9 to be clamped or released.

[0031] In this embodiment of the disclosure, such as Figure 1 , Figure 2 and Figure 5 As shown, the first fixing frame 6 has a V-shaped plate structure, and a set of through-hole slots is provided in the middle of the first fixing frame 6. The first fixing frame 6 and the second fixing frame 8 can clamp and fix the grouting device body 9, and can clamp grouting device bodies 9 with different outer diameters. When clamping the grouting device body 9, the second fixing frame 8 will also be embedded in the through-hole slot in the middle of the first fixing frame 6, thus avoiding conflict between the first fixing frame 6 and the second fixing frame 8.

[0032] In this embodiment of the disclosure, such as Figures 1-3 As shown, when both support rod 5 and support rod 7 slide towards the center of the main support plate 1, the second fixing frame 8 will embed into the opening groove in the middle of the first fixing frame 6. When both support rod 5 and support rod 7 slide towards both sides of the main support plate 1, the second fixing frame 8 will disengage from the first fixing frame 6. When the screw 3 rotates in the opposite direction, it will cause support rod 5 and support rod 7 to slide towards both sides of the main support plate 1. At this time, the first fixing frame 6 and the second fixing frame 8 will gradually disengage, and then the grouting device body 9 can be installed. Placed between the first fixing frame 6 and the second fixing frame 8, when the screw 3 rotates in the forward direction, it will cause the first support rod 5 and the second support rod 7 to slide towards the middle position of the main support plate 1. At this time, the first fixing frame 6 and the second fixing frame 8 will gradually move closer together. Therefore, the first fixing frame 6 and the second fixing frame 8 can firmly clamp and fix the grouting device body 9. Moreover, during this process, the second fixing frame 8 will also be embedded in the opening groove in the middle of the first fixing frame 6, thus avoiding the conflict between the first fixing frame 6 and the second fixing frame 8.

[0033] In this embodiment of the disclosure, such as Figure 1 , Figure 2 and Figure 6As shown, the second fixing frame 8 is also a V-shaped plate structure, and the height of the second fixing frame 8 is equal to the height of the middle opening slot of the first fixing frame 6. The second fixing frame 8 and the first fixing frame 6 cooperate to clamp and fix the grouting device body 9, and can clamp grouting device bodies 9 with different outer diameters. Moreover, when clamping the grouting device body 9, the second fixing frame 8 will also be embedded in the middle opening slot of the first fixing frame 6, thus avoiding conflict between the first fixing frame 6 and the second fixing frame 8.

[0034] In this embodiment of the disclosure, such as Figures 1-4 As shown, a long strip opening runs through the front and back of the main support plate 1. The rear ends of the first support rod 5 and the second support rod 7 can slide left and right in the long strip opening on the main support plate 1. When the first support rod 5 and the second support rod 7 slide left and right, the distance between the first fixing frame 6 and the second fixing frame 8 can be adjusted, thereby enabling the grouting device body 9 to be clamped or released.

[0035] Example 2, based on Example 1, such as Figures 1-6 As shown, both the first fixing frame 6 and the second fixing frame 8 are also covered with a layer of rubber. When the screw 3 rotates in the forward direction, the first fixing frame 6 and the second fixing frame 8 will gradually move closer together. Therefore, the first fixing frame 6 and the second fixing frame 8 can firmly clamp and fix the grouting device body 9. At this time, the rubber on the outside of the first fixing frame 6 and the second fixing frame 8 can increase the friction between the rubber and the outer wall of the grouting device body 9, making the clamping of the grouting device body 9 more stable.

[0036] The working principle of this embodiment is as follows: When grouting is required during road and bridge construction, the main support plate 1 is first placed at the grouting position by the rectangular plate at the bottom of the support leg 2. Then, the crank handle 4 drives the screw rod 3 to rotate in the reverse direction. When the screw rod 3 rotates in the reverse direction, it will cause the first support rod 5 and the second support rod 7 to slide towards both sides of the main support plate 1. At this time, the first fixing frame 6 and the second fixing frame 8 will gradually separate. Then, the grouting device body 9 can be placed between the first fixing frame 6 and the second fixing frame 8. Then, the crank handle 4 drives the screw rod 3 to rotate in the forward direction. When the screw rod 3 rotates in the forward direction, it will cause the first support rod 5 and the second support rod 7 to slide towards the middle position of the main support plate 1. At this time, the first support rod 5 and the second support rod 7 will slide towards the middle position of the main support plate 1. As the fixing frame 6 and the second fixing frame 8 gradually approach each other, the first fixing frame 6 and the second fixing frame 8 can firmly clamp and fix the grouting device body 9. During this process, the second fixing frame 8 will also be embedded in the opening groove in the middle of the first fixing frame 6, thus avoiding conflict between the first fixing frame 6 and the second fixing frame 8. Then, the pipe at the top of the grouting device body 9 can be connected to the external grout pump, and grouting can be carried out. During the grouting process, the worker does not need to hold the grouting device body 9 with his hand. After the grouting is completed, simply rotate the screw 3 in the opposite direction to release the first fixing frame 6 and the second fixing frame 8 from the grouting device body 9, and then the grouting device body 9 can be disassembled.
