AI Technical Summary
The existing vehicle-mounted grouting machine has its grouting equipment fixed at the rear of the vehicle and the material loading position is relatively high, which increases the length of the vehicle body, making it difficult to pass through narrow tunnels, and the grouting operation is intensive.
The vehicle-mounted grouting machine adopts a four-link lifting structure, using a lifting cylinder as a power source. The four links form a parallelogram structure to achieve parallel lifting of the grouting machine, increasing the lifting stroke and reducing the cylinder pulling arm. The grouting machine is suspended on the side of the vehicle frame, avoiding increasing the overall vehicle length.
Without increasing the length of the vehicle body, the grouting machine can be raised and lowered smoothly, reducing the material loading height, reducing the workload, and adapting to the passage requirements in narrow spaces.

[0022] Please see Figures 1-4This utility model provides an embodiment: a four-link lifting structure for a vehicle-mounted grouting machine, including a vehicle chassis 1, a lifting structure 11 on the side of the vehicle chassis 1, the lifting structure 11 including a first link mounting seat 2, two first links 6 rotatably mounted on the first link mounting seat 2, the ends of the two first links 6 away from the first link mounting seat 2 being rotatably connected to the grouting machine base 5, a grouting machine 4 being mounted above the grouting machine base 5, a cylinder seat 3 being provided on the side of the first link mounting seat 2, a lifting cylinder 7 being provided on the cylinder seat 3, a crossbar being provided between the two first links 6, the output end of the lifting cylinder 7 being rotatably connected to the crossbar, second links 9 being provided on the front and rear sides of the two first links 6, one end of the two second links 9 being rotatably connected to the grouting machine base 5, and the other end of the two second links 9 being rotatably connected to a second The connecting rod mounting seat 10 and two second connecting rod mounting seats 10 are connected to the vehicle chassis 1; the first connecting rod mounting seat 2 is rotatably connected to the two first connecting rods 6 via pins 8, the two first connecting rods 6 are rotatably connected to the grouting machine base 5 via pins 8, the lifting cylinder 7 is rotatably connected to the cylinder seat 3 via pins 8, a rod sleeve is fitted on the crossbar, the output end of the lifting cylinder 7 is rotatably connected to the crossbar via the rod sleeve, the two second connecting rods 9 are rotatably connected to the grouting machine base 5 via pins 8, and the two second connecting rods 9 are rotatably connected to the second connecting rod mounting seats 10 via pins 8; the first connecting rod mounting seat 2 is fixedly connected to the vehicle chassis 1, the grouting machine 4 is fixedly connected to the grouting machine base 5, the cylinder seat 3 is fixedly connected to the vehicle chassis 1, the crossbar is fixedly connected to the two first connecting rods 6, and the two second connecting rod mounting seats 10 are fixedly connected to the vehicle chassis 1.
[0023] The four-bar parallel lifting mechanism 11, consisting of two first connecting rods 6 and two second connecting rods 9, uses a lifting cylinder 7 as a power source and achieves parallel lifting by forming a parallelogram with four connecting rods.
[0024] According to the design requirements, since the cylinder stroke is limited within the chassis space and cannot reach the required lifting height of the grouting machine, the hydraulic cylinder pulling force is increased and the lever arm of the hydraulic cylinder pulling force is reduced. That is, the hinge point is selected at the center of the connecting rod slightly to the left, so that the lifting stroke is greater than the hydraulic cylinder stroke.

This ensures the stable operation of the grouting machine and keeps the material loading height low enough to reduce the workload.
[0026] Furthermore, each mounting part of the pin 8 is equipped with a copper sleeve and a locking bolt. The copper sleeve reduces direct metal-to-metal contact between the pin and the mounting hole, thereby reducing friction; the locking bolt prevents internal loosening.
[0027] Furthermore, both first links 6 and both second links 9 are V-shaped structures, and the included angle between the two sides of the two first links 6 and the two second links 9 is greater than 90 degrees. The connection point between the crossbar and the two first links 6 is located at the bends on the two sides.
[0028] Within a limited space, the four-bar parallel lifting mechanism can increase the lifting height without colliding with the vehicle body, and also keep the grouting machine 4 in parallel lifting.
[0029] Working principle of this utility model: When in use, the extension and retraction of the lifting cylinder 7 drives the two first connecting rods 6 and the two second connecting rods 9 to rotate, thereby raising and lowering the grouting machine base 5, which in turn drives the grouting machine 4 to rise and fall in parallel.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
