[0002] Grouting pumps are suitable for grouting and water blocking, filling gaps, reinforcing broken rock layers and other projects at construction sites such as mines, tunnels, water conservancy, subways, buildings, bridges, etc. Grouting pumps use compressed oil or compressed air as the power source, and use the large effective area ratio of the oil cylinder or air cylinder and the grouting cylinder, so that the cylinder body can generate a higher injection pressure with a smaller pressure.

[0003] Since the grouting pump is not fixed in its position when in use and may need to be constantly changed, it is necessary to disconnect and connect the power to the grouting pump many times. The existing grouting pump power connection method is relatively cumbersome. For a pump body with a capacitor, there are generally three wires: a common line, a main winding line, and a secondary winding line. First, the power line is connected to the common line; then, the main winding line is connected to one end of the capacitor, and the other end of the power line is also connected to this position; finally, the secondary winding line is connected to the other end of the capacitor, ensuring that all joints are tightened and wrapped with electrical tape to prevent leakage and short circuit; for a three-phase pump, the three-phase power line is directly connected to the three empty terminals of the motor, and the ground wire is connected to the motor housing; the existing pump body power connection method is relatively cumbersome, requiring each wire to be connected to the corresponding part separately, and ensuring that the connection part is accurate and tight, the power connection efficiency is slow, and it is easy to misalign multiple wire bodies and port connections, and the connection part between the wire body and the pump body may be disconnected when the grouting pump is moved, causing the grouting pump to suddenly stop working, affecting the grouting efficiency.

A quick-connect plug 6 for quick connection to the power supply is provided on the side of the bracket 5, and the quick-connect plug 6 is electrically connected to the electronic equipment in the electric control box 2 through a wire.

[0029] A grouting mechanism for extracting slurry and grouting is provided on the side of the upper surface of the trolley base 1 away from the electric control box 2. The grouting mechanism includes a hydraulic cylinder 16, a material cylinder 17, a working cylinder 18, a slurry inlet pipe 19 and a slurry outlet pipe 20. A support 21 for supporting the grouting mechanism is fixedly connected to the side of the upper surface of the trolley base 1 away from the bracket 5. The material cylinder 17 is fixedly mounted on the top of the support 21 and is fixedly connected to the fixed cylinder body of the hydraulic cylinder 16. The movable rod body of the hydraulic cylinder 16 is inserted into the interior of the material cylinder 17. Under the driving action of , its movable rod body can move inside the material cylinder 17, so that high pressure or negative pressure can be generated inside the material cylinder 17, so that the slurry is extracted and discharged through the two working cylinders 18; the number of the working cylinders 18 is two, and the two working cylinders 18 are respectively fixedly mounted on the two ends of the same side of the material cylinder 17 and connected with the interior thereof, the top ends of the two working cylinders 18 are fixedly mounted with a slurry outlet pipe 20 and the bottom ends are fixedly mounted with a slurry inlet pipe 19, and the oil inlets at both ends of the hydraulic cylinder 16 are respectively connected with the two second oil outlet pipes 13 through pipelines;

[0030] The movable rod of the hydraulic cylinder 16 is fixedly connected to the first baffle 22 and the second baffle 23 at one end away from the material cylinder 17. The operating rod of the reversing valve 10 can respectively abut the first baffle 22 and the second baffle 23. When the movable end of the hydraulic cylinder 16 moves toward one side of the material cylinder 17, the second baffle 23 at the rear end can abut against the operating rod in the inclined quasi-state and drive it to move to the vertical state. When the movable rod of the hydraulic cylinder 16 is completely inserted into the material cylinder 17, the second baffle 23 drives the operating rod to move to the vertical state. At this time, the operating rod will control the reversing valve 10 to reverse the oil circuit below, so that the hydraulic oil is discharged from the other second oil outlet pipe 13 to the other end of the hydraulic cylinder 16, thereby pushing the movable rod to move toward the end away from the material cylinder 17, and the hydraulic oil in the hydraulic cylinder 16 will be discharged outward and enter the hydraulic oil cooler 4 through the second oil outlet pipe 13 and the return oil pipe 14 to cool the hydraulic oil and then be discharged into the hydraulic oil tank 7 again.

[0031] A one-way valve ball structure is provided inside the connection between the working cylinder 18 and the pulp inlet pipe 19 and the pulp outlet pipe 20. The one-way valve ball structure includes a stop rod 24 and a one-way valve ball 25. The stop rod 24 at the connection between the working cylinder 18 and the pulp inlet pipe 19 is fixedly connected to the side of the working cylinder 18 close to the pulp inlet pipe 19, and the one-way valve ball 25 can block the pulp inlet pipe 19. The stop rod 24 at the connection between the working cylinder 18 and the pulp outlet pipe 20 is fixedly connected to the side of the pulp outlet pipe 20 close to the working cylinder 18, and the one-way valve ball 25 can block the top of the working cylinder 18.

[0032] The part of the movable rod body in the material cylinder 17 will divide the interior of the material cylinder 17 into two areas. When the movable rod body of the hydraulic oil cylinder 16 moves toward one end close to the material cylinder 17, the pressure in the area away from the fixed cylinder body of the hydraulic oil cylinder 16 increases, thereby applying positive pressure to the corresponding working cylinder 18. The one-way valve ball 25 at the bottom of the working cylinder 18 will completely block the slurry inlet pipe 19 below it, and the one-way valve ball 25 at the top will push upward under the pressure, but will abut under the blocking rod 24 and will not block the slurry outlet pipe 20. Therefore, the slurry in the material cylinder 17 and the working cylinder 18 will be discharged from the outlet pipe 20 under the push of the movable rod body. The slurry pipe 20 is discharged outward; at the same time, when the movable rod body moves toward the side close to the material cylinder 17, negative pressure is generated in the area close to the fixed cylinder body of the hydraulic oil cylinder 16, thereby applying negative pressure to the corresponding working cylinder 18. When negative pressure is generated in the working cylinder 18, the one-way valve ball 25 above it will be sucked tightly to the top opening of the working cylinder 18, thereby completely blocking the top, and the one-way valve ball 25 below is sucked up and abuts under its corresponding stop rod 24, which will not completely block the slurry inlet pipe 19, thereby enabling the slurry inlet pipe 19 to generate suction, extracting the slurry and storing it in the working cylinder 18 and material cylinder 17 on this side;

[0033] When the movable rod body moves to the terminal position, the slurry in the area of ​​the material cylinder 17 on the side away from the fixed cylinder body of the hydraulic oil cylinder 16 is completely discharged, and at the same time, the second baffle 23 behind the movable rod body will toggle the control lever of the reversing valve 10 to reverse the reversing valve 10. At this time, the hydraulic oil will drive the movable rod body of the hydraulic oil cylinder 16 to move in the opposite direction. Same as the above principle, when the movable rod body moves toward the end away from the material cylinder 17, negative pressure will be generated in the area of ​​the material cylinder 17 on the side away from the hydraulic oil cylinder 16, thereby generating negative pressure in the working cylinder 18 away from the fixed cylinder body of the hydraulic oil cylinder 16, so that it extracts the slurry, while high pressure will be generated in the area close to the hydraulic oil cylinder 16, thereby discharging the slurry originally extracted from the area of ​​the material cylinder 17 on the side close to the hydraulic oil cylinder 16 and the working cylinder 18 on the side close to the fixed cylinder body of the hydraulic oil cylinder 16 from the slurry outlet pipe 20. Through the reciprocating operation of the hydraulic oil cylinder 16, the working cylinders 18 on both sides can operate alternately, so that the slurry is continuously discharged outward, thereby improving the grouting efficiency.

[0034] In summary, the steps for using the grouting pump power quick-connect device are as follows:

[0035] 1. When the grouting pump needs to be used, the device can be moved to a specific location through the trolley base 1, and then the external power plug can be plugged into the quick-connect plug 6 to power on the grouting pump as a whole;

[0036] 2. After power is turned on, the hydraulic pump 3 will deliver the hydraulic oil in the hydraulic oil tank 7 to the hydraulic cylinder 16, thereby moving the movable rod of the hydraulic cylinder 16. The reversing valve 10 controls the hydraulic oil circuit to make the movable rod move back and forth.

[0037] 3. The part of the movable rod body in the material cylinder 17 will divide the interior of the material cylinder 17 into two areas. When the movable rod body of the hydraulic oil cylinder 16 moves toward one end close to the material cylinder 17, the pressure in the area away from the fixed cylinder body of the hydraulic oil cylinder 16 increases, thereby applying positive pressure to the corresponding working cylinder 18. The one-way valve ball 25 at the bottom of the working cylinder 18 will completely block the slurry inlet pipe 19 below it, and the one-way valve ball 25 at the top will push upward under the pressure, but will abut under the stop rod 24 and will not block the slurry outlet pipe 20. Therefore, the slurry in the material cylinder 17 and the working cylinder 18 will be pushed out from The slurry discharge pipe 20 is discharged outward; at the same time, when the movable rod body moves toward the side close to the material cylinder 17, negative pressure is generated in the area close to the fixed cylinder body of the hydraulic oil cylinder 16, thereby applying negative pressure to the corresponding working cylinder 18. When negative pressure is generated in the working cylinder 18, the one-way valve ball 25 above it will be sucked tightly to the top opening of the working cylinder 18, thereby completely blocking the top, and the one-way valve ball 25 below is sucked up and abuts under its corresponding stop rod 24, which will not completely block the slurry inlet pipe 19, thereby enabling the slurry inlet pipe 19 to generate suction, extracting the slurry and storing it in the working cylinder 18 and the material cylinder 17 on this side;

[0038] 4. When the movable rod moves to the terminal position, it will control the reversing valve 10. When the movable rod moves toward the end away from the material cylinder 17, negative pressure will be generated in the area of ​​the material cylinder 17 away from the hydraulic oil cylinder 16, thereby generating negative pressure in the working cylinder 18 away from the fixed cylinder body of the hydraulic oil cylinder 16, so that it can extract the slurry, and high pressure will be generated in the area close to the hydraulic oil cylinder 16, so that the slurry originally extracted in the area of ​​the material cylinder 17 close to the hydraulic oil cylinder 16 and the working cylinder 18 close to the fixed cylinder body of the hydraulic oil cylinder 16 will be discharged from the slurry outlet pipe 20. The reciprocating operation of the hydraulic oil cylinder 16 can make the working cylinders 18 on both sides operate alternately, so that the slurry can be discharged continuously, thereby improving the grouting efficiency.

[0039] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the scope of protection of the present invention.
