The grouting pump is mounted on the lifting platform 11, and the lifting platform 11 is driven to rise and fall relative to the lifting seat 12 by the linear drive mechanism 13. When loading or grouting, the linear drive mechanism 13 drives the lifting platform 11 downward until it contacts the ground, providing stable support for the grouting pump and effectively avoiding placement problems caused by uneven ground in the tunnel, thus exhibiting strong adaptability. When transferring or moving the grouting pump after completion, the linear drive mechanism 13 drives the lifting platform 11 upward until it reaches the specified ground clearance, at which point the vehicle is started for transfer or movement. The lifting platform 11 ensures both convenient loading and vehicle passability, making it highly practical. The grouting pump can be transferred and moved along with the anchor bolt trolley, saving the time of separate pump transport, effectively improving construction efficiency and reducing labor and material costs. Optionally, the linear drive mechanism 13 is a hydraulic cylinder, which is used for direct push, eliminating the wire rope structure, reducing the risk of wire rope breakage due to long-term use, lowering maintenance costs, ensuring safety and reliability, and making it more durable.

The fasteners 26 on the second connecting plate 22 and the third connecting plate 23 pass through the oblong holes 25 and connect to the frame 3. There is no need to change the size and structure of the intermediate bracket 2, nor is there any need to modify or cut the frame 3. Adjusting the position of the fasteners 26 in the oblong holes 25 can adapt to multiple car frames 3, which has strong versatility. It can be understood that the number of through holes 24 and oblong holes 25 can be increased or decreased according to the installation requirements, and the number of fasteners 26 can be adjusted accordingly.
