Pneumatic dual-liquid grouting pumps require a stable support surface to ensure the proper functioning of their internal mechanical components. If the ground is uneven, vibrations are transmitted to the equipment, affecting the synchronization and accuracy of the various components. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0019] The beneficial effects of the utility model are:

[0020] 1. By setting up the telescopic plate, the telescopic plate can be taken out from the inside of the chassis by sliding and lowered to the ground, thereby increasing the contact area between the entire device and the ground; solving the problem that the operation of the pneumatic double-liquid grouting pump may be affected when the ground is unstable due to the limited contact area between the fixed frame and the ground; at the same time, by setting up the buffer push rod and the spring push rod, the impact force generated when the grouting pump is running will be transmitted to the surface of the buffer push rod and the surface of the spring push rod, and the impact force will be absorbed by the buffer push rod and the spring push rod, further ensuring that the internal parts of the grouting pump will not be damaged due to vibration force during operation.

[0021] 2.

While the vibration force is absorbed by the buffer push rod and the spring push rod, the existence of the rolling ball and the outer shell can prevent the chassis and the telescopic plate from moving under the action of the grouting pump.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 5 A stable pneumatic double-liquid grouting pump includes a chassis 1 and a grouting pump body 3 arranged above the chassis 1.

The round rod 401 is fixedly connected to the bottom of the grouting pump body 3. The sleeve 402 is set at the bottom of the grouting pump body 3. The round rod 401 passes through the sleeve 402 and extends to the outside of the sleeve 402. The outer wall of the round rod 401 is rotatably connected to the inner wall of the sleeve 402. The sleeve 402 can rotate on the outer wall of the round rod 401. The connector 403 3 is fixedly connected to the top of the chassis 1, the buffer push rod 404 is arranged above the chassis 1, the output end of the buffer push rod 404 is fixedly connected to the outer wall of the sleeve 402, the grouting pump body 3 can apply a force to the buffer push rod 404 through the sleeve 402, the ball 405 is fixedly connected to the bottom end of the buffer push rod 404, the ball 405 is movably connected to the connecting piece 403, and the buffer push rod 404 can move on the top of the connecting piece 403 through the ball 405.

[0032] The auxiliary unit includes a protruding rod 406, a spring push rod 407, a limit plate 408 and a shell 409. The protruding rod 406 is fixedly connected to the outer wall of the grouting pump body 3, the spring push rod 407 is fixedly connected to the outer wall of the protruding rod 406, the limit plate 408 is fixedly connected to the outer wall of the spring push rod 407, and the shell 409 is arranged on the outside of the grouting pump body 3. One end of the spring push rod 407 passes through the outer wall of the shell 409 and extends to the inside of the shell 409. The outer wall of the spring push rod 407 is slidably connected to the inner wall of the shell 409. The spring push rod 407 can slide inside the shell 409 under the action of the grouting pump body 3.

[0033] By providing the telescopic disc 2, the telescopic disc 2 can be taken out from the inside of the chassis 1 by sliding, and lowered and fixed on the ground, thereby increasing the contact area between the entire device and the ground; solving the problem that the operation of the pneumatic dual-liquid grouting pump may be affected when the ground is unstable due to the limited contact area between the fixing frame and the ground; at the same time, by providing the buffer push rod 404 and the spring push rod 407, the impact force generated when the grouting pump is running will be transmitted to the surface of the buffer push rod 404 and the surface of the spring push rod 407, and the impact force will be absorbed by the buffer push rod 404 and the spring push rod 407, further ensuring that the internal parts of the grouting pump will not be damaged due to the action of vibration force during operation.

[0034] The support assembly 5 includes a fixing member 501, a support member 502 and a fixing rod 503. The fixing member 501 is fixedly connected to the top of the chassis 1.

The end of the fixing rod 503 away from the support member 502 is fixedly connected to the outer wall of the shell 409. The fixing rod 503 can support the shell 409.

[0035] By setting the ball 405 and the shell 409, the vibration force generated when the grouting pump is running will drive the buffer push rod 404 to move through the ball 405, and the spring push rod 407 will move inside the shell 409 through the protruding rod 406. While the vibration force is absorbed by the buffer push rod 404 and the spring push rod 407, the existence of the ball 405 and the shell 409 can prevent the chassis 1 and the telescopic plate 2 from moving under the action of the grouting pump.

[0036] The working principle of this stable pneumatic double-liquid grouting pump is as follows: the telescopic plate 2 is taken out from the inside of the chassis 1 by sliding, and the chassis 1 and the telescopic plate 2 are fixed to the ground, and the grouting pump is started. The impact force generated when the grouting pump is running will drive the buffer push rod 404 and the rolling ball 405 to shake. When the grouting pump shakes, it will drive the spring push rod 407 to move inside the shell 409 through the protruding rod 406. At this time, the impact force generated when the grouting pump is running will be transmitted to the inside of the buffer push rod 404 and the spring push rod 407, and absorbed by the buffer push rod 404 and the spring push rod 407. The grouting pump can operate on the top of the chassis 1.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
