Technical Field

[0001] The utility model relates to the technical field of grouting machines, in particular to an intelligent cement-water glass double-liquid grouting machine. Background Art

[0002] Double-liquid grouting machines are widely used in tunnels, mine excavation working faces for grouting and blocking water; rock tunnels and concrete shaft walls for grouting and blocking water leakage; reinforcement of tunnel cracks, broken rock masses, and evacuated rocks; anchor grouting; backfill grouting and grouting to prevent surface subsidence, prevent landslides, and correct the deflection of buildings. When grouting the foundation, water glass is usually added to it to accelerate solidification. The existing double-liquid grouting machine usually uses a cylinder with a ball valve to inject the mortar sucked in at the slurry inlet through the outlet into the foundation and other locations. However, in actual use, the inventor found that the driving method using a hydraulic cylinder requires a more complex hydraulic system for control, and also requires components such as pumps, pipes, and valves. The pipelines are complicated, making the overall structure of the grouting machine more complicated, and the hydraulic drive method requires liquid to transmit power, which is more difficult to maintain and has higher manufacturing and maintenance costs.

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] As mentioned in the background technology, the existing double-liquid grouting machine usually uses a hydraulic cylinder hydraulic drive mode, and the piston rod 42 is driven to retract or extend by the power of the hydraulic oil, and the mortar is sucked into the slurry inlet 2 and then sprayed out at the slurry outlet in coordination with the opening and closing of the ball valve. However, the inventor found that there are many defects. The hydraulic cylinder requires more combined structures and the equipped hydraulic system is more complicated. The investment and maintenance costs of the hydraulic cylinder are high. Therefore, the inventor has made improvements on the basis of the existing grouting machine and designed a new double-liquid grouting machine, which is explained in detail below with reference to the drawings.

[0029] This embodiment provides an intelligent cement-water glass double liquid grouting machine, see Figure 1, including a grouting machine body 1, and in order to facilitate the grouting machine to move to the grouting area, moving wheels 11 are correspondingly installed at the four corners of the bottom of the grouting machine body 1, and two slurry inlets 2 are arranged on the grouting machine body 1, and the bottoms of the two slurry inlets 2 are connected with electric ball valves 3, and the driving mechanism 4 and the slurry outlet pipe 5 are connected through the electric ball valve 3. The slurry inlet and outlet principles in this scheme are consistent with the grouting machine in the prior art, and also include a piston rod 42 and a piston cylinder 41 as in the prior art. Through the reciprocating movement of the piston rod 42 in the piston cylinder 41, the electric ball valve 3 is connected to the slurry inlet 2 or the slurry outlet pipe 5 to realize the suction and ejection of mortar and complete the grouting action. Therefore, the diagram and principle of this part of the content are not redundantly described, and the prior art can be used. The main innovation of the design of this scheme is the drive of the piston rod 42. The improved part is described below.

[0030] In the present embodiment, the two slurry inlets 2 are connected with a slurry inlet pipe 6, and are connected with the slurry making mechanism through the slurry inlet pipe 6. It should be noted that in the present embodiment, the two slurry inlet pipes 6 are connected, and a tee pipe 8 is installed between them, so that the same mortar or different mortars are mixed before grouting, and a hopper 9 is connected above the tee pipe 8 to receive the mortar prepared by the slurry making mechanism, and the mortar is divided into the two slurry inlet pipes 6 through the tee pipe 8, and then sprayed out at the slurry outlet pipe 5 through the respectively connected electric ball valves 3, and the hopper 9 is connected to the upper end of the grouting machine body 1 through the bracket 10, which can support the hopper 9 and reduce its violent shaking.

[0031] On the basis of the above structure, as one of the main design points of this scheme, the driving mechanism 4 includes a piston cylinder 41 connected to the electric ball valve 3, and a piston rod 42 is slidably arranged in the piston cylinder 41. The specific installation design of the piston cylinder 41 is that a base 7 is arranged at the bottom of the grouting machine body 1, and the bottom end of the piston cylinder 41 is installed with the base 7, and the piston rod 42 is arranged through the upper end of the base 7, which can support the piston cylinder 41 and ensure the stability of the piston rod 42 during movement.

[0032] What is different from the prior art is that Figure 2 In this solution, the movement of the piston rod 42 replaces the hydraulic drive method in the traditional technology. Specifically, a power device is installed at the bottom of the grouting machine body 1, and the output end of the power device is connected to the piston rod 42, which can drive the piston rod 42 to slide up and down along the piston cylinder 41. The power device includes a power motor 43, and the output end of the power motor 43 is connected to a crank rocker mechanism 44. The upper end of the crank rocker mechanism 44 is hinged to the bottom of the piston rod 42. The crank is driven to rotate by the power motor 43, and then the crank drives the rocker to reciprocate up and down, and finally drives the piston rod 42 to move up and down along the piston cylinder 41, thereby realizing the suction of mortar at the slurry inlet 2 and the ejection of mortar at the slurry outlet pipe 5.

[0033] Secondly, the output end of the power motor 43 extends to the inside of the base 7, that is, the output shaft of the power motor 43 extends into the base 7, and the crank rocker mechanism 44 is located in the base 7, so that the base 7 can protect the crank rocker mechanism 44 and reduce damage to it caused by other external objects.

[0034] As one of the other main design points of this scheme, the grouting machine of this scheme can perform quantitative grouting, wherein the grouting pipe 6 is equipped with an electromagnetic valve 12, which can control its on and off, and the electromagnetic valve 12 can automatically control the on and off of the grouting pipe 6 through the control system, and the grouting pipe 5 is equipped with an electromagnetic flowmeter 13, which can monitor the flow of mortar flowing through the grouting pipe 5. After the mortar flow reaches the required mortar value input, it is fed back to the control system to control the grouting work to stop, and the grouting machine body 1 is provided with a controller 14, and the electric ball valve 3, the power motor 43, the electromagnetic valve 12 and the electromagnetic flowmeter 13 are all connected to the controller 14. Electrical connection, the controller 14 can control the rotation of the electric ball valve 3, the opening and closing of the power motor 43 and the electromagnetic valve 12, and can also receive the flow signal fed back by the electromagnetic flowmeter 13. During grouting, the required mortar amount is input into the control system, and the controller 14 controls the power motor 43, the electric ball valve 3 and the electromagnetic valve 12 to work and perform grouting. The electromagnetic flowmeter 13 monitors the amount of mortar flowing through the slurry outlet pipe 5 and feeds back to the controller 14 until the feedback value reaches the input value. The controller 14 controls the power motor 43 and the electric ball valve 3 to stop working, and at the same time closes the electromagnetic valve 12 to stop grouting, thereby improving the automation degree of the grouting machine.

[0035] Embodiment 2

[0036] Since water glass is added to the grouting position during grouting to speed up the solidification of the grouting, two independent grouting pipes are required. Figure 3 , wherein the upper ends of the slurry inlet pipes 6 connected to the two slurry inlets 2 are respectively connected to hoppers 9, and the two slurry inlet pipes 6 are no longer connected through a tee pipe 8, but are two independent pipelines, which are respectively connected to the corresponding slurry sources. The other designs are the same as those in Example 1, so that the two slurry outlet pipes 5 can spray different types of mortars to meet the needs of the project during grouting.
