[0021] Adopting the above solution: Through the synergistic effect of the first pusher 3 and the first hydraulic push rod 4, combined with the flexibility of adjusting the telescopic rod 6 and the clamping plate 7, the firm clamping of grouting pumps 8 of different sizes can be achieved, thereby improving the versatility and operation efficiency of the device.

[0022] One side of the adjustment slide rail 1 is fixedly provided with an extension plate 9. Above the extension plate 9, a second pusher 10 is fixedly provided. Below the extension plate 9, an electric support rod 11 is fixedly provided. The side of the second pusher 10 is fixedly connected to a second hydraulic push rod 12. The side of the second hydraulic push rod 12 is fixedly connected to a fixing plate 13. The side of the fixing plate 13 is fixedly provided with a cross plate 2. The side of the cross plate 2 is fixedly provided with a limiting plate 14. The side of the limiting plate 14 is provided with a limiting hole 15.

[0023] Adopting the above solution: Through the drive of the second pusher 10 and the second hydraulic push rod 12, the cross plate 2 and the limiting plate 14 slide in the adjustment slide rail 2, thereby realizing the adaptation and fixation of grouting pipes 81 of different diameters.

[0024] Below the adjustment slide rail 1, a support plate movable seat 16 is fixedly provided. Inside the support plate movable seat 16, a support plate 17 is rotatably provided. The side of the support plate movable seat 16 is fixedly provided with a roller 18.

[0025] Adopting the above solution: The combined design of the support plate movable seat 16 and the support plate 17 provides the necessary support and stability for the device. At the same time, with the assistance of the roller 18, it is convenient for the movement and positioning of the device.

[0026] The clamping plate 7 can be adapted to grouting pumps 8 of different sizes through the push of the first pusher 3 and the adjustment of the telescopic rod 6. The clamping plate 7 plays a role in firmly clamping the grouting pump 8.

[0027] Adopting the above solution: Through the combined action of pushing and telescoping, the precise matching and firm fixation of the size of the grouting pump 8 are realized, which helps to improve the stability and accuracy of the grouting pump 8 during the working process and reduce the operation problems caused by vibration or deviation.

[0028] The second pusher 10 drives the second hydraulic push rod 12, so that the cross plate 2 slides inside the adjustment slide rail 1, thereby adjusting the position of the limiting plate 14 to facilitate the adaptation of grouting pipes 81 of different sizes. The grouting pipe 81 passes through the limiting hole 15, and the electric support rod 11 provides a supporting force for the extension 9.

[0029] Adopting the above solution: The electric support rod 11 provides a supporting force for the extension plate 9, ensuring the structural stability during the adjustment process. This design enhances the operation safety of the device for the grouting pipe 81.

[0032] The working principle of the present utility model is as follows: First, the first hydraulic push rod 4 is driven to expand and contract by adjusting the first pusher 3 on the slide rail 1, thereby driving the connecting plate 5 and the adjusting telescopic rod 6 connected thereto to move. The flexible adjustment of the adjusting telescopic rod 6 in cooperation with the clamping plate 7 can adapt to and firmly clamp the grouting pumps 8 of different sizes, ensuring the stability and accuracy of the grouting pump 8 during the working process. The grouting pump 8 performs grouting operations through the grouting pipeline 81 below it. At the same time, in order to further enhance the flexibility and adaptability of the device, a second pusher 10 is provided on the extension plate 9 on one side of the adjusting slide rail 1. This pusher drives the fixed plate 13 and the cross plate 2 connected thereto to slide inside the adjusting slide rail 1 by driving the expansion and contraction of the second hydraulic push rod 12. This design allows the position of the adjusting limit plate 14 to be adjusted, so as to adapt to grouting pipelines 81 of different diameters. The grouting pipeline 81 is stably fixed after passing through the limit hole 15. In addition, the electric support rod 11 provides the necessary support force for the extension plate 9 to ensure the stability of the structure. At the bottom of the device, the support plate 17 in the support plate movable seat 16, with the assistance of the rollers 18, not only provides the necessary support and stability force but also can be conveniently stored in the support plate movable seat 16 when needed to reduce the overall size of the device, facilitating transportation and storage.
