Description

Technical Field

[0001] This utility model relates to the technical field of coal mine support systems, specifically a monitoring device for coal mine emulsion pump stations. Background Technology

[0002] In the process of fully mechanized coal mining (longwall mining), the longwall mining emulsion pump station needs to deliver high-pressure emulsion to the hydraulic support of the longwall mining face to maintain the pressure of the hydraulic support and ensure the working quality of the longwall mining equipment. When the emulsion pump station is working, it is necessary to monitor the working status of the emulsion pump station. At this time, a monitoring device for the emulsion pump station of fully mechanized coal mining is needed.

[0003] Most existing emulsion pump stations rely on manual judgment based on experience and subjective feelings to determine their working status. The pressure stability of the emulsion delivery system is a crucial factor in determining the stability of the support system. However, current emulsion pump stations rely entirely on accumulators for stabilization, but accumulators rely entirely on the compressibility of gas for regulation, resulting in limited regulation capabilities. Utility Model Content

[0004] The purpose of this utility model is to provide a monitoring device for coal mine emulsion pump stations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A monitoring device for a coal mine emulsion pump station includes:

[0007] The main body of the pumping station includes a casing;

[0008] The monitoring structure includes an energy storage tank, which is fixedly installed on the lower edge of one side of the chassis. A first piston is slidably engaged inside the energy storage tank via a guide rod assembly. A balance tank is fixedly installed on the upper surface of the energy storage tank, and a second piston is slidably engaged inside the balance tank via a guide rod assembly. The energy storage tank and the balance tank are interconnected via a connecting pipe.

[0009] The controller includes a base bar, the front end of which is fixedly connected to the balance tank.

[0010] Furthermore, the main body of the pumping station also includes:

[0011] The base plate, one end of the upper surface of which is fixedly connected to the chassis;

[0012] An explosion-proof motor is fixedly installed on the other end of the upper surface of the base plate;

[0013] A tire coupling, one side of which is fixedly connected to the output end of an explosion-proof motor, and the other side of which is fixedly connected to a shaft inside the machine housing.

[0014] Furthermore, the main body of the pumping station also includes:

[0015] Pump head, which is fixedly installed on the front side of the chassis;

[0016] An unloading valve is fixedly installed on one side of the pump head.

[0017] Furthermore, the monitoring structure also includes:

[0018] A linkage guide rod is sealed and slidably sleeved at the rear end of the energy storage tank, and one end of the linkage guide rod is fixedly connected to the No. 1 piston;

[0019] An electric actuator is fixedly installed at the rear end of the balance tank, and the output end of the electric actuator passes through the balance tank and is fixedly connected to the second piston.

[0020] Furthermore, the controller also includes:

[0021] The first sliding resistor block is fixedly embedded in the front end of the bottom side of the base strip;

[0022] The second sliding resistor block is fixedly embedded in the rear end of the bottom side of the base strip;

[0023] A sliding slot is provided on the bottom side of the base strip, the first sliding resistor block, and the second sliding resistor block.

[0024] Furthermore, the controller also includes:

[0025] A conductive slider, the upper end of which is slidably engaged with a sliding slot;

[0026] The base block is fixedly installed at the lower end of the conductive slider and at the upper side of one end of the linkage guide rod.

[0027] A conductive slide rail, wherein the conductive slide rail is slidably sleeved with the middle part of the conductive slider;

[0028] The slide rail support is fixedly installed at both ends of the conductive slide rail, and two slide rail supports are fixedly installed at both ends of the bottom side of the base strip.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] 1. The controller controls the movement of piston No. 2 inside the balance tank based on the movement position of piston No. 1 inside the accumulator tank. When the hydraulic pressure inside the accumulator tank is too high, piston No. 2 moves and draws emulsion from inside the accumulator tank through the connecting pipe to relieve pressure and store a certain amount of emulsion. When the hydraulic pressure inside the accumulator tank is too low, piston No. 2 moves and squeezes the emulsion stored in the balance tank into the accumulator tank to replenish the emulsion. While storing liquid energy, it can provide a certain dynamic adjustment capability for the emulsion hydraulic pressure and improve this adjustment capability through the balance tank.

[0031] 2. When the first piston moves, it synchronously drives the conductive slider to slide inside the second sliding resistor block through the transmission of the linkage guide rod. When the hydraulic pressure inside the energy storage tank is too high, the first piston moves to the rear end of the energy storage tank, and the conductive slider is driven by the linkage guide rod to move into the second sliding resistor block, providing power to the drive motor of the electric actuator. The second piston is used to draw the emulsion inside the energy storage tank into the balance tank. When the hydraulic pressure inside the energy storage tank is too low, the conductive slider will move into the first sliding resistor block, connecting another power supply. The positive and negative poles are reversed to supply power to the electric actuator, causing the drive motor of the electric actuator to rotate in the reverse direction. Then, the second piston is used to squeeze the emulsion stored in the balance tank into the energy storage tank, realizing dynamic control. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1-6 In this embodiment of the present invention, a monitoring device for a coal mine emulsion pump station includes a pump station body 1, a monitoring structure 2, and a controller 3. The pump station body 1 includes a housing 104; the monitoring structure 2 includes an energy storage tank 201, which is fixedly installed on the lower edge of one side of the housing 104. A first piston 202 is slidably connected inside the energy storage tank 201 through a guide rod assembly. A balance tank 204 is fixedly installed on the upper surface of the energy storage tank 201. A second piston 206 is slidably connected inside the balance tank 204 through a guide rod assembly. The energy storage tank 201 and the balance tank 204 are interconnected through a connecting pipe 205; the controller 3 includes a base bar 301, the front end of which is fixedly connected to the balance tank 204.

[0041] Specifically, a certain amount of gas is injected into the space behind piston 202 inside the accumulator tank 201 according to the emulsion supply pressure demand. The front end of the accumulator tank 201 is connected to the emulsion delivery channel inside the casing 104. The compressibility of the gas is used to store liquid energy, thereby stabilizing the emulsion pressure in the delivery system. The controller 3 controls piston 206 to move inside the balance tank 204 based on the movement position of piston 202 inside the accumulator tank 201. When the hydraulic pressure inside the accumulator tank 201 is too high, piston 206 moves and draws emulsion from inside the accumulator tank 201 through the connecting pipe 205 to relieve pressure and store a certain amount of emulsion. When the hydraulic pressure inside the accumulator tank 201 is too low, piston 206 moves and squeezes the emulsion stored in the balance tank 204 into the accumulator tank 201 to replenish the emulsion. While storing liquid energy, it can provide a certain dynamic adjustment capability for the emulsion hydraulic pressure, and the balance tank 204 can improve this adjustment capability.

[0042] Example 1

[0043] like Figure 2As shown, in this embodiment, the pump station body 1 also includes a base plate 101, an explosion-proof motor 102, a tire coupling 103, a pump head 105, and an unloading valve 106. One end of the upper surface of the base plate 101 is fixedly connected to the housing 104; the explosion-proof motor 102 is fixedly installed on the other end of the upper surface of the base plate 101; one side of the tire coupling 103 is fixedly connected to the output end of the explosion-proof motor 102, and the other side of the tire coupling 103 is fixedly connected to the shaft inside the housing 104; the pump head 105 is fixedly installed on the front side of the housing 104; and the unloading valve 106 is fixedly installed on one side of the pump head 105.

[0044] In this embodiment, the explosion-proof motor 102 provides power to rotate the three-crankshaft inside the housing 104, which in turn drives the plug inside the housing 104 to reciprocate, converting mechanical energy into hydraulic energy at the pump head 105 and outputting pressurized liquid.

[0045] like Figure 3-4 As shown, in this embodiment, the monitoring structure 2 also includes a linkage guide rod 203 and an electric actuator 207. The linkage guide rod 203 is sealed and slidably sleeved on the rear end of the energy storage tank 201, and one end of the linkage guide rod 203 is fixedly connected to the first piston 202. The electric actuator 207 is fixedly installed on the rear end of the balance tank 204, and the output end of the electric actuator 207 passes through the balance tank 204 and is fixedly connected to the second piston 206.

[0046] In practice, the movement of piston 202 is transmitted to energy storage tank 201 via linkage guide rod 203. After being regulated by controller 3, piston 206 is driven by electric push rod 207 to move inside balance tank 204.

[0047] Example 2

[0048] Based on Embodiment 1, this invention supplements the specific method of driving the monitoring structure 2 through the controller 3, which was not mentioned in Embodiment 1.

[0049] like Figure 3 , Figure 5As shown, in this embodiment, the controller 3 further includes a first sliding resistor block 302, a second sliding resistor block 303, a sliding groove 304, a conductive slider 305, a base block 306, a conductive slide rail 307, and a slide rail support 308. The first sliding resistor block 302 is fixedly embedded in the front end of the bottom side of the base strip 301; the second sliding resistor block 303 is fixedly embedded in the rear end of the bottom side of the base strip 301; the sliding groove 304 is formed in the base strip 301 and the first sliding resistor block 305. Block 302 is connected to the bottom side of the second sliding resistor block 303; the upper end of the conductive slider 305 is slidably engaged with the sliding slot 304; the base block 306 is fixedly installed at the lower end of the conductive slider 305 and at the upper side of one end of the linkage guide rod 203; the conductive slide rail 307 is slidably sleeved with the middle part of the conductive slider 305; the slide rail support 308 is fixedly installed at both ends of the conductive slide rail 307 and the two slide rail supports 308 are fixedly installed at both ends of the bottom side of the base strip 301.

[0050] In practice, when piston 202 moves, it synchronously drives conductive slider 305 to slide inside sliding resistor block 303 via linkage guide rod 203. When the hydraulic pressure inside energy storage tank 201 is too high, piston 202 moves to the rear end of energy storage tank 201, and conductive slider 305 is driven by linkage guide rod 203 to move into sliding resistor block 303, providing power to the drive motor of electric actuator 207. Piston 206 then draws the emulsion inside energy storage tank 201 into balance tank 204. When the hydraulic pressure inside energy storage tank 201 is too low, conductive slider 305 moves into sliding resistor block 302, connecting another power source with the positive and negative poles reversed to supply power to electric actuator. Power is supplied to 207, causing the drive motor of the electric actuator 207 to rotate in reverse. This, in turn, uses the second piston 206 to squeeze the emulsion stored in the balance tank 204 into the energy storage tank 201, achieving dynamic control. A section of sliding groove 304 in the middle of the bottom side of the base strip 301 provides the range of motion for the first piston 202 when the pressure inside the energy storage tank 201 is within the normal range. At the same time, by using a sliding resistor instead of a trigger switch, the conductivity efficiency can be dynamically changed based on the actual pressure level and the resistance change caused by the position of the conductive slider 305 on the resistor. This allows for dynamic control of the operating power of the conductive slide rail 307, and the working speed of the conductive slide rail 307 can be dynamically controlled according to the degree of pressure exceeding the range.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
