[0001] The present invention relates to the field of grouting pump trucks, and more specifically, to a remotely controlled electric crawler grouting pump truck for coal mines and a method of using the same. Background Art
[0002] With the rapid improvement of the mechanization level of coal mines, more and more attention has been paid to issues such as safe production, reducing the labor intensity of workers, and improving production efficiency. At present, grouting construction has been widely used in various fields such as filling reinforcement, water blocking and anti-seepage, and fire prevention in coal mines.
[0003] Traditional grouting operations mostly use fixed grouting pumps, which need to be manually carried or transported by monorail cranes, transport vehicles, etc. during transfer. There are also small grouting pumps installed on trolleys or large and medium-sized grouting pumps installed on crawler chassis. However, due to the poor road conditions underground in coal mines, there are problems such as large slopes, potholes, mud, and water accumulation, so hand-push grouting pumps are not applicable. The traditional grouting pumps installed on crawler chassis require operators to operate the control mechanism on the equipment body near the edge of the equipment or stand on the station board set up by the equipment to drive. This driving method has huge safety hazards when the equipment goes up and down, reverses, or passes through potholes, mud, water and other sections, and it is very easy to cause unbearable personal injuries to the operator. If a cab is set on the equipment, due to the relatively small underground space, it may be necessary to reverse for a long distance on sections where it is inconvenient to turn around. This situation also has a large safety hazard. Therefore, how to produce a grouting equipment that can be remotely controlled and suitable for the harsh environment of coal mines has become one of the technical problems that urgently need to be solved in this field.

[0019] Example 1 like Figure 1 , Figure 3 as well as Figure 4 As shown, the present invention provides a remotely controlled electric crawler grouting pump truck for coal mines, comprising an upper mounting mechanism 1, a crawler traveling mechanism 2, a grouting mechanism 3 and a remote control mechanism 4, wherein the upper mounting mechanism 1 provides power for the crawler traveling mechanism 2 and the grouting mechanism 3, and a mode switching valve is installed on the upper mounting mechanism 1 for switching between a set traveling mode and a grouting mode; The upper mounting mechanism 1 includes a hydraulically controlled proportional multi-way valve 107, a hydraulic oil tank 109 and an explosion-proof motor 110; The remote control mechanism 4 includes a high-pressure pipe bundle 401 connected to the hydraulically controlled proportional multi-way valve 107 , so that the hydraulically controlled proportional multi-way valve 107 can be remotely controlled by the remote control mechanism 4 .
[0020] The equipment of the present invention has two working modes, namely, traveling and grouting, and shares a power system (i.e., the upper mounting mechanism 1), which is switched by the switching valve on the equipment body. In normal use, the hydraulic oil tank 109 supplies hydraulic oil, and the hydraulic proportional multi-way valve 107 controls the oil flow and direction of the crawler-type traveling mechanism 2 and the grouting mechanism 3. At the same time, the explosion-proof motor 110 drives the hydraulic plunger pump to provide a high-pressure oil source for the entire hydraulic system, thereby providing power.
[0021] When the pump truck needs to be moved, the switching valve on the equipment body is switched to the driving mode, and the high-pressure pipe bundle 401 is connected to the hydraulically controlled proportional multi-way valve 107 on the equipment body. Then, the staff stands at a certain installation distance from the equipment and controls the reversing and valve core opening of the hydraulically controlled proportional multi-way valve 107 through the remote control mechanism 4, thereby driving the movement of the pump truck. When the pump truck moves to a suitable position, the movement of the equipment is stopped through the remote control mechanism 4. Then, the equipment body is switched to the grouting mode through the tangential valve, and the grouting can be driven by the above-mentioned power. It should be noted that in the grouting mode, the remote control mechanism 4 cannot control the hydraulically controlled proportional multi-way valve 107, thereby preventing safety accidents that may be caused by misoperation. In summary, when the pump truck of the present invention is moving, the operator can maintain a certain safety distance from the equipment, thereby obtaining a better field of vision and safety. Moreover, the equipment adopts an explosion-proof design and uses a mining explosion-proof motor 110 as a power source, so it can operate normally in an environment containing explosive gases in coal mines. Moreover, since there are no electrical components except the explosion-proof motor 110, it not only increases the difficulty of equipment maintenance but also greatly improves the safety of the equipment working in an environment containing explosive gases.
[0022] Example 2 like Figure 1 - Figure 4 As shown, this embodiment describes in detail the specific structures of the upper mounting mechanism 1, the crawler-type walking mechanism 2 and the remote control mechanism 4 in Embodiment 1.
[0023] The upper mounting mechanism 1 also includes a vehicle speed switching valve 104, an air cooler 105, a middle air inlet cover 106, a frame 108, a rear air inlet cover 111 and a machine body. A hydraulic oil tank 109 and a machine body are installed on the top of the frame 108, and the two are fitted together. The middle air inlet cover 106 and the rear air inlet cover 111 are embedded and fixed on the machine body. An explosion-proof motor 110, an air cooler 105 and a hydraulic proportional multi-way valve 107 are installed in the machine body. The vehicle speed switching valve 104 is installed on the surface of the machine body and is connected to the explosion-proof motor 110 through a signal line to control the explosion-proof motor 110. As can be seen from the above, the vehicle speed switching valve 104 on the upper mounting mechanism 1 has a high-speed gear and a low-speed gear, which can be switched freely according to driving needs to control the driving speed of the equipment. The air cooler 105 is of suction type, which is used for heat dissipation of the hydraulic system. During operation, the ambient temperature air is sucked into the air cooler 105 through the air inlet hood with holes (the middle air inlet hood 106 and the rear air inlet hood 111) to cool the hydraulic oil. The cooling fan is driven by a hydraulic motor to ensure the temperature stability of the hydraulic system during operation, thereby improving the safety of the equipment in dangerous environments. Furthermore, a coil rack 101 is installed on the middle air inlet hood 106, and the length of the high-pressure pipe bundle 401 is set to five meters, which is coiled on the coil rack 101. When driving, the pipe bundle of appropriate length can be released as needed to avoid the entanglement of the high-pressure pipe bundle 401. A flow adjustment handle 102 and a pressure gauge assembly 103 are also installed on the middle air inlet hood 106. The flow adjustment handle 102 can control the flow rate and the start and stop of the grouting mechanism 3. The pressure gauge assembly 103 consists of a pressure gauge shield and a pressure gauge, which can monitor the pressure values of the grouting system and the hydraulic system in real time, thereby improving the safety of the grouting work.
[0024] The crawler-type walking mechanism 2 includes a crawler 201, a guide wheel 202, a load-bearing wheel 203, a driving wheel 204, a walking motor 205, a crawler frame 206, a mounting support 207 and a chassis. The chassis is connected to the upper mounting mechanism 1 by bolts through the mounting support 207. A crawler frame 206 is installed on the chassis. There are two walking motors 205, which are installed on the front and rear sides of the crawler frame 206 respectively and driven by a hydraulic proportional multi-way valve 107. The two sides of the crawler frame 206 respectively carry the guide wheel 202, the load-bearing wheel 203 and the driving wheel 204. The shafts of the three are installed on the crawler frame 206 through bearings. The output shaft of the walking motor 205 is connected to the driving wheel 204. The crawler 201 surrounds the driving wheel 204 and the guide wheel 202, and presses on the load-bearing wheel 203. According to the above, the crawler-type walking mechanism 2 is composed of crawler 201, guide wheel 202, load-bearing wheel 203, driving wheel 204, walking motor 205, crawler frame 206, etc. The left and right walking motors 205 are driven by hydraulic proportional multi-way valve 107, which can realize forward and reverse rotation and speed adjustment. When the two motors rotate in the same direction and at the same speed, the driving wheel 204 drives the crawler 201 to rotate, so that the equipment can move forward or backward; when the rotation directions are the same but the speeds are different, the steering is achieved by the speed difference of the crawlers on both sides; rotating in the opposite direction can achieve a U-turn on the spot.
[0025] The remote control mechanism 4 also includes a pilot handle valve group 402, a bracket 403 and a shoulder strap 404 connected to the high-pressure tube bundle 401. The shoulder strap 404 is installed on both sides of the bracket 403. The surface of the bracket 403 is integrally formed with a support platform, and the pilot handle valve group 402 is installed on the support platform.
[0026] The remote control mechanism 4 is composed of a high-pressure pipe bundle 401, a pilot handle valve group 402, a bracket 403, and a shoulder strap 404. The high-pressure pipe bundle 4 is used to connect the hydraulic proportional multi-way valve 107 and the pilot handle valve group 402. The pilot handle valve group 402 controls the flow and direction of the hydraulic oil by controlling the reversing and valve core opening of the proportional multi-way valve, so as to realize the forward, backward, steering, U-turn and other driving actions of the equipment. The bracket 403 is preferably a flying wing bending structure, which can increase the fit between the remote control mechanism 4 and the operator's abdomen and reduce the left and right swing of the remote control mechanism 4. The remote control mechanism 4 is suspended on the operator's neck through the shoulder strap 404, which is convenient for the operator to completely free his hands and realize sensitive control of the grouting pump truck. In addition, the shoulder strap 404 can be easily removed when the pump truck is out of control or other special conditions occur, so as to avoid the operator being dragged and causing safety accidents.
[0027] Example 3 like Figure 1 and Figure 5 As shown, this embodiment provides a grouting mechanism 3 that can effectively improve the grouting efficiency. The following is the specific structure of the grouting mechanism 3: the grouting mechanism 3 includes an automatic reciprocating hydraulic cylinder 302 and slurry cylinders 301 arranged at both ends thereof, and the slurry cylinders 301 at both ends are automatically reciprocated by the automatic reciprocating hydraulic cylinder 302. The automatic reciprocating hydraulic cylinder 302 is provided with a logic valve 303 and a reversing valve group, and the slurry cylinder 301 is equipped with a one-way valve 304.
[0028] During use, the logic valve 303 can sense whether the piston has reached the limit position through the change of pressure difference and send a reversing signal to the reversing valve group through the X and Y ports. After receiving the reversing signal, the reversing valve group alternately supplies oil to the A and B ports to realize the automatic reciprocating motion of the hydraulic cylinder. The hydraulic cylinder drives the slurry cylinders 301 at both ends to reciprocate automatically, and cooperates with the four one-way valves 304 on the slurry cylinders 301 to realize slurry suction and discharge. In general, the grouting mechanism 3 adopts double-cylinder double-action, has two slurry suction ports and two slurry discharge ports, and can perform double-liquid grouting or single-liquid grouting, which greatly improves the efficiency of grouting and reduces the interruption or unsmoothness of grouting that may be caused by untimely or inaccurate manual operation.

If you want to go forward or backward, make the two travel motors 205 rotate in the same direction and adjust the flow and direction to control the same speed; if you want to turn, make the two motors rotate in the same direction but adjust the speed differently; if you want to turn around on the spot, make the two motors rotate in opposite directions; S1.5: When it is necessary to stop traveling, the valve core of the hydraulic proportional multi-way valve 107 is adjusted to a position where the travel motor 205 stops rotating through the pilot handle valve group 402; S2: How to use the grouting mode: S2.1: Switch the mode switching valve on the equipment body to the grouting mode; S2.2: Control the grouting flow rate and start or stop the grouting mechanism 3 through the flow regulating handle 102. During the grouting process, the flow regulating handle 102 can be adjusted in time according to actual needs to achieve a suitable grouting flow rate; S2.3: Observe the pressure value displayed by the pressure gauge assembly 103, monitor the pressure of the grouting system and the hydraulic system in real time, and ensure that the pressure is within a safe range. If the pressure fluctuates abnormally, the grouting operation should be stopped immediately and the equipment should be checked for any faults.

It can operate normally in the environment containing explosive gas in the coal mine. In addition, since there are no electrical components except the explosion-proof motor 110, it not only increases the maintenance difficulty of the equipment but also greatly improves the safety of the equipment working in the environment containing explosive gas. During operation, ambient air at room temperature is sucked into the air cooler 105 through the air inlet hood with holes to cool the hydraulic oil. The cooling fan is driven by a hydraulic motor to ensure that the temperature of the hydraulic system is stable during operation, thereby improving the safety of the equipment in dangerous environments. The vehicle speed switching valve 104 on the upper mounting mechanism 1 has a high speed gear and a low speed gear, which can be switched freely according to driving requirements to control the driving speed of the equipment; The length of the high-pressure tube bundle 401 is set to five meters, and it is coiled on the coil rack 101. When driving, the tube bundle of appropriate length can be released as needed, thereby avoiding the entanglement of the high-pressure tube bundle 401; The pressure gauge assembly 103 is composed of a pressure gauge shield and a pressure gauge, which can monitor the pressure values of the grouting system and the hydraulic system in real time, thereby improving the safety of the grouting work; The grouting mechanism 3 adopts double-cylinder double-action, has two grouting ports and two grouting discharge ports, and can perform double-liquid grouting or single-liquid grouting, which greatly improves the efficiency of grouting and reduces the interruption or unsmoothness of grouting that may be caused by untimely or inaccurate manual operation.
