Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fully mechanized mining equipment, and in particular to an emulsion pump station and fully mechanized mining mechanical equipment for coal mines. Background Art
[0002] In the process of coal mining, the emulsion pump station, as a key hydraulic equipment, undertakes the task of accurately supplying liquid to the working face. In traditional emulsion pump stations, the transmission method is mostly in the form of a reduction box and a motor connected through a coupling.
[0003] However, the traditional connection method has obvious shortcomings: First, due to the large rotational inertia of the motor, emulsion pump and its coupling, the static accuracy of the system is not high, which affects the dynamic performance and makes it impossible to achieve accurate and stable fluid supply control of the hydraulic pump. Secondly, the narrow working environment of the thin coal seam chute places higher requirements on the power density of the equipment, requiring the equipment to maintain a compact size while maintaining high efficiency. If high power density and high integration are pursued alone, the heat dissipation capacity of the system may be significantly reduced, thereby affecting the overall performance and stable operation of the pumping station. Finally, as a middleware, although the coupling improves the connectivity between different components, its elastomer has poor reliability and is prone to failure in the complex environment underground. It is also inconvenient to replace and adjust, which increases maintenance costs. Summary of the invention
[0004] The present invention provides an emulsion pump station and coal mine comprehensive mining mechanical equipment, which are used to solve the problems of low static accuracy, poor dynamic performance and low coupling reliability caused by the transmission mode in the prior art, and to achieve a comprehensive mining equipment solution with high precision and stable liquid supply control and improved power density and integration of the equipment.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0024] Most existing emulsion pump station products use a solution where the motor and pump are connected via a coupling. This traditional connection form has a large moment of inertia of the motor, emulsion pump, and the coupling used for connection in the middle, resulting in low static accuracy of the system, affecting dynamic performance, and failing to achieve accurate fluid supply to the working face. In addition, the narrow working environment of the thin coal seam chute places higher requirements on the power density of various equipment in the equipment train, including the emulsion pump station. Under such conditions, if high power density and high integration are pursued blindly, the heat dissipation capacity of the pump station system will be greatly reduced. In addition, the elastomer of the coupling has poor reliability and is not convenient for replacement and adjustment underground.
[0025] The present invention proposes an emulsion pumping station in the form of a motor pump, which uses a hollow shaft motor, extends the crankshaft of the power box of the emulsion pump into the hollow shaft of the motor, and uses a flat key or a spline instead of a coupling to achieve the connection between the motor and the pump. This design reduces the additional rotational inertia brought by the coupling, so that precise control of the liquid supply to the working face can be achieved through a variable frequency motor. This solution also shortens the axial dimension of the entire pumping station and improves the power density of the pumping station, making it more suitable for use in environments with limited space such as thin coal seams. Through the above design, not only are the problems of low liquid supply accuracy, poor dynamic performance, and inconvenient maintenance existing in traditional emulsion pumping stations solved, but the overall performance of the system is also improved by optimizing the structure, simplifying the maintenance process, reducing maintenance costs, and enhancing the reliability and service life of the system.
[0026] Combine the following Figures 1 to 4 A specific embodiment of the emulsion pumping station of the present invention is described.
[0027] like Figure 1 and Figure 2 As shown, the present invention provides an emulsion pump station, including: an emulsion pump device, including a power mechanism and a pump body 11, the pump body 11 is connected to the emulsion pipeline, a plunger assembly is arranged in the pump body 11, the power mechanism includes a power box 12, a crankshaft for driving the plunger assembly is arranged in the power box 12, and a driving end 13 of the crankshaft extends out of the power box 12; a motor 20 is arranged on one side of the emulsion pump device, a hollow structure 21 is arranged on the output shaft end of the motor 20, the driving end 13 of the crankshaft is inserted into the hollow structure 21, and the driving end 13 and the hollow structure 21 are relatively fixed in the rotation direction; a base 30, the emulsion pump device and the motor 20 are integrated and arranged on the upper surface of the base 30.
[0028] Specifically, the emulsion pump station realizes direct connection between the motor 20 by designing the output shaft of the motor 20 as a hollow structure 21 and inserting the crankshaft in the power box 12 of the emulsion pump directly into the hollow part of the output shaft of the motor 20. This design removes the coupling in the traditional connection method, reduces the moment of inertia, improves the static accuracy and dynamic response speed of the system, and can more accurately and stably control the liquid supply to the working face. In addition, due to the cancellation of the coupling, the entire system structure becomes more compact, which helps to improve the power density of the equipment and makes it more suitable for use in environments with limited space such as thin coal seams. Through the above structure, not only the problems of low liquid supply accuracy, poor dynamic performance and inconvenient maintenance encountered by traditional emulsion pump stations in coal mining are solved, but also the overall performance of the system is improved through optimized design. Through the direct connection method, not only the mechanical loss is reduced and the efficiency is improved, but also the maintenance process is simplified, the maintenance cost is reduced, and the reliability and service life of the system are enhanced. At the same time, transmission components such as gears and gear shafts are eliminated, the weight of the equipment is further reduced, the equipment is lightweight, and the transportation and maintenance costs are reduced. By directly driving the emulsion pump through the motor 20, the cost of transmission components, couplings and coupling protection covers is saved, further saving the overall cost of the equipment.
[0029] Furthermore, the emulsion pump station can also optimize the connection between the crankshaft and the output shaft of the motor 20, such as using a keyway or other form of locking mechanism, to ensure a stable connection between the two in the direction of rotation, while facilitating disassembly and maintenance. In addition, for the design of the base 30, it is possible to consider using shock-absorbing materials or structures to reduce the vibration generated during operation, and further improve the stability and safety of the pump station operation. In addition, in order to solve the heat dissipation problem, a reasonable heat dissipation channel can be designed on the base 30 or a heat sink can be added to enhance the heat dissipation capacity of the system and ensure long-term stable operation.
[0030] According to an emulsion pump station of the present invention, a limit key structure is provided between the outer peripheral surface of the transmission end 13 and the inner peripheral surface of the hollow structure 21. By providing the limit key structure between the outer peripheral surface of the transmission end 13 of the crankshaft and the inner peripheral surface of the hollow structure 21 of the output shaft of the motor 20, a stable connection between the two in the rotation direction is ensured. The function of the limit key structure is to prevent relative rotation, ensure the efficiency and stability of power transmission, and allow convenient installation and disassembly, which is convenient for maintenance and overhaul.
[0031] Furthermore, the limit key structure can be designed in various forms, such as a flat key 15, a semicircular key or a spline, etc., to adapt to different working conditions and load conditions. In addition, in order to ensure the durability and reliability of the limit key structure, wear-resistant and corrosion-resistant materials can be selected to manufacture the limit key, and sufficient safety margin can be considered in the design to cope with the harsh working environment underground in coal mines. At the same time, a lubrication structure can also be designed around the limit key to reduce friction and extend the service life.
[0032] like Figure 4 As shown, according to an emulsion pump station of the present invention, the limit key structure includes an outer peripheral spline 14 arranged on the outer peripheral surface of the transmission end 13, and an inner peripheral spline 22 arranged on the inner peripheral surface of the hollow structure 21; the outer peripheral spline 14 is adapted to the shape of the inner peripheral spline 22. By arranging the outer peripheral spline 14 on the outer peripheral surface of the transmission end 13 of the crankshaft, and arranging the inner peripheral spline 22 on the inner peripheral surface of the hollow structure 21 of the output shaft of the motor 20, and the outer peripheral spline 14 is adapted to the shape of the inner peripheral spline 22, a stable connection between the two in the rotation direction is achieved. The spline connection has high torsional strength and impact resistance, and can maintain a stable connection under complex working conditions in coal mines, reducing the failure rate. Through the spline connection, the static accuracy and dynamic response speed of the system can be significantly improved, ensuring that the emulsion pump station can control the liquid supply more accurately. Among them, a reasonable lubrication structure, such as an oil groove or an oil nozzle, can be designed at the spline connection to reduce friction and extend the service life. Sensors (such as torque sensors, position sensors, etc.) can also be installed at the spline connection or adjacent locations to monitor the connection status in real time, detect and deal with potential problems in a timely manner, and ensure stable operation of the system.
[0033] like Figure 3 As shown, according to an emulsion pump station of the present invention, the limit key structure includes a flat key 15; the inner peripheral surface of the hollow structure 21 is provided with an inner peripheral keyway 23 extending along the axial defense line of the output shaft, the width of the inner peripheral keyway 23 is adapted to the width of the flat key 15, and the length of the inner peripheral keyway 23 is longer than the length of the flat key 15; the outer peripheral surface of the transmission end 13 is provided with an outer peripheral keyway matching the shape of the flat key 15, or the flat key 15 is fixed to the outer peripheral surface of the transmission end 13. By providing the flat key 15 and the keyway on the outer peripheral surface of the transmission end 13 of the crankshaft and the inner peripheral surface of the hollow structure 21 of the output shaft of the motor 20, a stable connection between the two in the rotation direction is achieved.
[0034] Specifically, an inner circumferential keyway 23 extending along the axial direction of the output shaft is provided on the inner circumferential surface of the hollow structure 21 of the output shaft of the motor 20, and the width of the keyway is adapted to the width of the flat key 15 to ensure that the flat key 15 can be smoothly embedded. The length of the keyway is longer than the length of the flat key 15, so that a certain installation and adjustment margin can be provided. The outer circumferential surface of the transmission end 13 can be provided with an outer circumferential keyway matching the shape of the flat key 15, and the flat key 15 is embedded in the keyway; or, the flat key 15 can be directly fixed on the outer circumferential surface of the transmission end 13, and fixed by welding, fasteners, etc., to ensure that it will not loosen during operation. The flat key 15 has a simple connection structure, is easy to install and disassemble, is convenient for daily maintenance and overhaul, and reduces maintenance costs.
[0035] Preferably, in the above embodiment, high-strength, wear-resistant materials are selected to manufacture the flat key 15 and the keyway to improve their durability under harsh working conditions. A reasonable lubrication structure, such as an oil groove or an oil nozzle, can also be designed on the contact surface of the flat key 15 and the keyway to reduce friction and extend the service life. Preferably, the flat key 15 and the keyway are subjected to appropriate heat treatment, such as carburizing, quenching, etc., to improve their surface hardness and wear resistance.
[0036] like Figure 1 and Figure 2 As shown, according to an emulsion pump station of the present invention, a mounting bracket 31 is arranged on the base 30; a first support frame 32 is arranged at the bottom of the motor 20, and the position of the first support frame 32 relative to the mounting bracket 31 in the horizontal longitudinal direction parallel to the output shaft is adjustable. Specifically, the emulsion pump station is provided with the mounting bracket 31 on the base 30, and the first support frame 32 is provided at the bottom of the motor 20, so that the position of the first support frame 32 relative to the mounting bracket 31 in the horizontal longitudinal direction parallel to the output shaft is adjustable. By adjusting the position of the first support frame 32, the axial distance between the motor 20 and the emulsion pump device can be adjusted, thereby improving the applicability and being applicable to various types of emulsion pump devices. Through the above-mentioned bracket structure, the applicability of the system is improved, so that the emulsion pump station can better adapt to different types of emulsion pump devices. By adjusting the position of the first support frame 32, the installation and alignment of the motor 20 and the emulsion pump device can be quickly completed on site, simplifying the installation and debugging process and ensuring the stable operation of the system.
[0037] In order to further optimize the emulsion pump station, a slide rail or a threaded adjustment mechanism can be designed between the first support frame 32 and the mounting bracket 31 to achieve more precise adjustment, and the first support frame 32 can be fixed in the desired position by a locking device (such as a locking nut or a locking pin) to ensure that it will not move during operation. In addition, a vibration damping pad or other vibration damping structure can be set between the base 30 and the motor 20 and the emulsion pump device to further reduce vibration transmission and improve the operating stability of the system. Preferably, the centering monitoring sensor can also be installed to monitor the centering status in real time to further improve the overall performance and reliability of the emulsion pump station.
[0038] Preferably, according to an emulsion pump station of the present invention, along the horizontal longitudinal direction, the mounting bracket 31 is provided with a plurality of mounting holes 33 on the side of the first support frame 32; and the first support frame 32 is provided with a positioning structure adapted to the mounting holes 33. By providing the mounting bracket 31 on the base 30 and providing the first support frame 32 at the bottom of the motor 20, the position of the first support frame 32 relative to the mounting bracket 31 in the horizontal longitudinal direction parallel to the output shaft is adjustable. Along the horizontal longitudinal direction, the mounting bracket 31 is provided with a plurality of mounting holes 33 on the side of the first support frame 32, and the first support frame 32 is provided with a positioning structure adapted to the mounting holes 33. By adjusting the position of the first support frame 32, the axial distance between the motor 20 and the emulsion pump device can be adjusted, thereby improving the applicability and being applicable to various types of emulsion pump devices.
[0039] According to an emulsion pump station of the present invention, a second support frame 34 is provided on the base 30; a clamping mechanism 35 adapted to the shape of each bottom corner of the power box 12 is provided on the top of the second support frame 34. The clamping mechanism 35 is preferably an adjustable threaded clamping member, and by tightening the threaded clamping member, a clamping force can be applied to a total of eight sides of the four bottom corners of the power box 12, thereby achieving stable support and fixation of the power box 12. The clamping mechanism 35 not only ensures the stability and reliability of the power box 12 during operation, but also provides a flexible installation and adjustment method through the adjustable threaded clamping member, which is adapted to power boxes 12 of different sizes and shapes, further improving the applicability and flexibility of the system.
[0040] In addition, the clamping mechanism 35 can also be a hydraulic clamp, a pneumatic clamp, etc. Specifically, the hydraulic clamp and the pneumatic clamp provide clamping force through a hydraulic or pneumatic system, and can evenly apply pressure on a total of eight sides of the four bottom corners of the power box 12 to achieve stable support and fixation of the power box 12. For example, the hydraulic clamp can convert the pressure of the hydraulic oil into a clamping force through a hydraulic cylinder and a piston structure, and the magnitude of the clamping force can be accurately controlled by adjusting the pressure of the hydraulic system. The pneumatic clamp uses the pressure of compressed air to achieve clamping through a cylinder and a piston structure, and the fine control of the clamping force can also be achieved by adjusting the air pressure.
[0041] like Figure 1 As shown, according to an emulsion pump station of the present invention, a lubricating oil circuit is arranged on the base 30; an oil pump 41 for driving the lubricating oil to circulate along the lubricating oil circuit is arranged on the lubricating oil circuit; a recovery interface 42 and an output interface 43 connected to the power box 12 are respectively arranged at both ends of the lubricating oil circuit; the recovery interface 42 is connected to the bottom of the power box 12; the output interface 43 is connected to the top of the power box 12 or one side of the power box 12. Through the lubricating oil circuit, not only can the moving parts in the power box 12 be fully lubricated, friction and wear can be reduced, and the service life of the equipment can be extended, but also heat can be taken away by the circulation of the lubricating oil, the temperature inside the power box 12 can be reduced, and the thermal stability of the system can be improved. In addition, by setting the recovery interface 42 at the bottom of the power box 12 and the output interface 43 at the top or one side of the power box 12, it can be ensured that the lubricating oil is evenly distributed in the power box 12, the lubrication effect can be improved, and the local overheating and wear caused by uneven distribution of the lubricating oil can be reduced.
[0042] It is understandable that the lubricating oil in the power box 12 will settle at the bottom under the action of gravity, so setting the recovery interface 42 at the bottom is conducive to the efficient recovery of the lubricating oil, avoiding the accumulation of lubricating oil at the bottom of the power box 12, reducing waste and uneven lubrication effect. At the same time, the output interface 43 is connected to the top or one side of the power box 12, and the lubricating oil can be supplied from the top or the side to provide a continuous lubrication effect for the components close to the top, ensuring that all moving parts in the power box 12 can be fully lubricated, reducing friction and wear, and improving the operating reliability and life of the system. In addition, through the circulation of the lubricating oil, the heat inside the power box 12 can also be taken away, the internal temperature can be reduced, and the thermal stability of the system can be improved.
[0043] Furthermore, according to an emulsion pump station of the present invention, a filter 44 and a lubricating oil container 45 which are sequentially connected in series with the oil pump 41 are preferably provided on the lubricating oil circuit. Among them, the filter 44 can effectively remove impurities in the lubricating oil, keep the lubricating oil clean, and further reduce the wear of moving parts. The lubricating oil container 45 is used to store the lubricating oil to ensure that there is a sufficient supply of lubricating oil in the lubricating oil circuit, and can realize automatic circulation and filtration of the lubricating oil, thereby improving the maintenance convenience and operational reliability of the system. In addition, temperature sensors and pressure sensors can be provided on the lubricating oil circuit to monitor the temperature and pressure of the lubricating oil in real time, ensure that the system operates in the best condition, promptly discover and deal with potential problems, and further improve the overall performance and reliability of the emulsion pump station.
