Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic mechanism dry mist nozzle control systems, and in particular to an intelligent hydraulic mechanism dry mist nozzle control system and method. Background Art

[0002] In order to ensure the normal operation of the mining machine, it is necessary to set up hydraulic mechanisms in sequence in the straight direction in front of the mining face. After the hydraulic mechanism can support the top layer, the guide rails can be arranged in the straight direction below and used for the movement of the mining machine. In order to suppress dust and reduce temperature, the hydraulic mechanism needs to be equipped with dry mist nozzles facing the mining face. For dust suppression considerations, the dry mist nozzles need to be in a normally open state. When the mining machine is working, in order to ensure dust suppression and cooling effects, the spray flow of the dry mist nozzles needs to be in a higher state. The method adopted by existing equipment is generally to increase the flow uniformly, and the flow of several nozzles cannot be increased separately. In addition, due to the influence of the installation structure of the dry mist nozzles, the spray direction can only be towards the mining face and cannot be adjusted according to the movement of the mining machine. Summary of the invention

[0003] In order to solve the above-mentioned problems that the flow rate of the dry mist nozzle cannot be adjusted in time and the spray direction is single, the present invention provides an intelligent hydraulic mechanism dry mist nozzle control system.

[0004] The technical solution of the present invention is as follows:

[0005] An intelligent hydraulic mechanism dry mist nozzle control system comprises a plurality of hydraulic mechanisms arranged in a straight line, and a guide rail is provided on one side of the hydraulic mechanism close to the mining face, the distance between the guide rail and the hydraulic mechanism can be adjusted, and the length direction of the guide rail is the same as the arrangement direction of the plurality of hydraulic mechanisms;

[0006] The guide rail is provided with a mining machine capable of moving in the length direction, and the mining machine is provided with two mining rollers of different heights on the same vertical plane, and the mining machine is provided with a position encoder synchronized therewith;

[0007] The minimum distance between the two mining drums is greater than the width of three hydraulic mechanisms;

[0008] The hydraulic mechanism is provided with a dual-axis adjustment platform at the upper position of the guide rail, and the dual-axis adjustment platform is located in the middle of the hydraulic mechanism and is provided with a dry mist nozzle, and the dry mist nozzle can rotate in two planes, horizontal and vertical, relative to the hydraulic mechanism;

[0009] It also includes a main control terminal, the input end of which is connected to a position encoder, and the output end of which is connected to a dual-axis adjustment platform.

[0010] Different from the existing methods, the flow rate and angle of the dry mist nozzle can be adjusted by the position of the mining drum, which can achieve better dust suppression and cooling effects, and can also avoid the problem of increased water consumption caused by increasing the flow rate of all dry mist nozzles at the same time.

[0011] In order to facilitate the individual control of the hydraulic mechanism, the main control terminal includes an identification coding module, which can perform ID coding on each hydraulic mechanism in sequence along the length direction of the guide rail;

[0012] The main control terminal also includes a response hydraulic mechanism identification module, which can identify the three hydraulic mechanisms closest to the mining drum as response hydraulic mechanisms according to the real-time position of the mining drum on the guide rail.

[0013] The flow control method of the above-mentioned dry mist nozzle is that the dry mist nozzle is provided with two liquid inlets, and the diameters of the two liquid inlets are different, one of the liquid inlets is connected to the normally open main pipe through an independent solenoid valve, and the other liquid inlet is connected to the additional pipe through an independent solenoid valve;

[0014] The preset critical value of the atomization flow of the dry fog nozzle is z, then the flow range of the dry fog nozzle in the normally open main pipe is 0.6z-0.8z, the flow in the additional pipe is z, and the normally open main pipe is in a normally open state, the additional pipe is in a normally closed state, and the normally open main pipe can be closed after the hydraulic mechanism is identified as a response hydraulic mechanism, and the additional pipe can be opened.

[0015] The pitch angle adjustment is achieved in that the main control terminal also includes a pitch angle adjustment module, and the pitch angle adjustment module can adjust the pitch angle of the dry mist nozzle of the response hydraulic mechanism according to the real-time position of the mining drum on the guide rail.

[0016] The method for realizing horizontal angle adjustment is that the main control terminal further includes a horizontal angle adjustment module, and the horizontal angle adjustment module can adjust the horizontal angle of the dry mist nozzle of the response hydraulic mechanism according to the real-time position of the mining drum on the guide rail.

[0017] A method for controlling a dry mist nozzle of an intelligent hydraulic mechanism uses the above-mentioned dry mist nozzle control system of an intelligent hydraulic mechanism and comprises the following steps:

[0018] S1. Responding hydraulic mechanism identification. The main control terminal obtains the real-time coordinate of the mining machine on the guide rail as Q according to the encoder. Then the real-time coordinates of the two mining drums of the mining machine on the guide rail are Q+a and Qb, and a and b are the horizontal distances between the mining drum and the center of the mining machine. According to the position of the hydraulic mechanism relative to the guide rail, the first three hydraulic mechanisms that are close to the two mining drums are identified as responding hydraulic mechanisms.

[0019] S2, the water volume is increased, the solenoid valve connected to the normally open main pipe in the hydraulic mechanism in step S1 is closed, and the solenoid valve connected to the additional pipe is opened;

[0020] S3, horizontal angle adjustment, according to the real-time coordinates Q+a and Qb of the excavation drum and the difference between the center coordinates of the response hydraulic mechanism, the horizontal deflection angle J of the dry mist nozzle is adjusted through the dual-axis adjustment platform, and the calculation formula of J is tan(J)=X / Y, where X is the difference between the center coordinate value of the response hydraulic mechanism and the real-time coordinates of the excavation drum, and Y is the difference in the distance between the dry mist nozzle and the excavation drum in the direction perpendicular to the length of the guide rail;

[0021] S4. Pitch angle adjustment. According to the height difference between each mining drum and the guide rail, the pitch deflection angle K of the dry mist nozzle responding to the hydraulic mechanism is adjusted through the dual-axis adjustment platform, and the calculation formula of K is tan(K)=Y / C, where C is the difference in vertical height between the dry mist nozzle and the mining drum.

[0022] The method for identifying the responding hydraulic mechanism is that in step S3, the total length of the preset guide rail is M, and the total number of the hydraulic mechanisms is N, then the center coordinate values ​​of each hydraulic mechanism arranged in sequence are M / 2N, 3*M / 2N, 5*M / 2N···(2N-1)*M / 2N, and the first three hydraulic mechanism IDs that are close to the distance between the two mining drums can be obtained according to the difference between the above center coordinate values ​​and Q+a and Qb, and they can be identified as the responding hydraulic mechanisms.

[0023] To clean the equipment, it also includes:

[0024] Step S5, cleaning operation: the solenoid valve connected to the normally open main pipe and the solenoid valve connected to the additional pipe in the response hydraulic mechanism are opened simultaneously.

[0025] Since the dry mist nozzle changes from spraying to spraying liquid columns, in step S5, a first cleaning deflection angle T is preset. When the two solenoid valves are opened at the same time, the horizontal deflection angle J of the response hydraulic mechanism is alternately deflected in two directions to the first cleaning deflection angle T.

[0026] Further on the basis of the above structure, in step S5, a second cleaning deflection angle U is preset, and when the two solenoid valves are opened at the same time, the pitch deflection angle K of the response hydraulic mechanism deflects the second cleaning deflection angle U alternately in two directions.

[0027] The beneficial effects of the present invention are as follows: the present invention is a control system for dry mist nozzles of an intelligent hydraulic mechanism. Different from the conventional method of uniformly increasing the flow rate of all dry mist nozzles, the present device can control the corresponding dry mist nozzle flow rate to increase by identifying and responding to the hydraulic mechanism, thereby avoiding the ineffective increase of the flow rate of other dry mist nozzles. At the same time, by identifying and responding to the hydraulic mechanism, the dry mist nozzle can also be controlled to cooperate with the movement and steering of the mining drum to obtain better dust suppression and cooling effects. Moreover, by utilizing the critical characteristics of the dry mist nozzle flow rate, the dry mist nozzle can spray liquid columnar water flow and clean the equipment, thereby avoiding the need to set up additional cleaning equipment.

[0034] like Figure 1 , 2 An intelligent hydraulic mechanism dry mist nozzle control system is shown, comprising a plurality of hydraulic mechanisms 1 arranged in a straight line direction, and a guide rail is provided on the side of the hydraulic mechanism 1 close to the mining face, and the distance between the guide rail and the hydraulic mechanism 1 can be adjusted. By adjusting the guide rail, the position of the guide rail can be changed, and deeper mining can be carried out in the above manner, and the length direction of the guide rail is the same as the arrangement direction of the plurality of hydraulic mechanisms 1, ensuring that the direction of the guide rail is constant, so as to ensure that the guide rail will not deviate from the support and protection range of the hydraulic mechanism 1.

[0035] Afterwards, on the basis of the above structure, further, a mining machine capable of moving along the length direction is arranged on the guide rail, and two mining rollers 21 with different heights are arranged on the same vertical plane of the mining machine, and the mining machine is provided with a position encoder synchronized therewith, wherein the position encoder can provide real-time feedback on the position of the mining machine on the guide rail, thereby facilitating the control of the dry mist nozzle according to this position information, and since the mining roller 21 is a part of the mining machine, its position is fixed relative to the mining machine without manual adjustment, so the coordinate position of the mining roller 21 on the guide rail can be calculated only according to the position encoder of the mining machine.

[0036] In the above structure, the premise for achieving subsequent adjustment is that the minimum spacing between the two excavation rollers 21 is greater than the width of the three hydraulic mechanisms 1. Through the above method, it can be ensured that there will be no confusion when adjusting the direction of the dry mist nozzles of the three adjacent hydraulic mechanisms. In the above structure, the method for achieving the angle adjustment of the dry mist nozzle is that the hydraulic mechanism 1 is provided with a dual-axis adjustment platform 11 at the upper position of the guide rail. The dual-axis adjustment platform 11 can be directly purchased and obtained, so its structure is not repeated. It should be noted that the dual-axis adjustment platform 11 is located in the middle of the hydraulic mechanism 1 and is provided with a dry mist nozzle 3. The dry mist nozzle 3 can rotate in two planes, horizontally and vertically, relative to the hydraulic mechanism 1. When the pitch angle of the dry mist nozzle 3 is adjusted in the vertical direction, it can be applied to excavation rollers 21 of different heights, and it can also be applied to the excavation roller 211 after the guide rail is moved relative to the hydraulic mechanism 1 as a whole, so that the dry mist nozzle 3 is applied to the excavation roller 211 after moving to different positions.

[0037] Moreover, the above structures do not require manual control. For this purpose, the above system also includes a main control terminal, the input end of which is connected to the position encoder, and the output end is connected to the dual-axis adjustment platform 11, that is, the dual-axis adjustment platform 11 can be controlled to rotate in various directions according to the position of the position encoder.

[0038] In order to facilitate the individual control of the hydraulic mechanism 1, the main control terminal includes an identification coding module, which can perform ID coding on each hydraulic mechanism 1 in sequence along the length direction of the guide rail;

[0039] The main control terminal also includes a response hydraulic mechanism 1 identification module, which can identify the three hydraulic mechanisms 1 closest to the mining drum 21 as the response hydraulic mechanism 1 according to the real-time position of the mining drum 21 on the guide rail. In the above manner, the dry mist nozzle can be controlled according to the identified response hydraulic mechanism 1. First, after the real-time position of the mining drum 21 is obtained, the position of each hydraulic mechanism 1 relative to the guide rail is also preset. Therefore, by obtaining the difference, the three hydraulic mechanisms closest to it can be obtained. At the same time, when the difference between two hydraulic mechanisms and the mining drum 21 is the same, an interference item can be excluded, that is, a secondary judgment is set. When the coordinate difference between the two hydraulic mechanisms and the mining drum 21 is the same, the one with the larger coordinate value on the guide rail can be selected, which can avoid the influence of other interference items and ensure that the six hydraulic mechanisms corresponding to the two mining drums 21 can be identified as the response hydraulic mechanism.

[0040] Afterwards, after the identification is completed, the pitch angle adjustment is achieved in that the main control terminal also includes a pitch angle adjustment module, which can adjust the pitch angle of the dry mist nozzle 3 of the response hydraulic mechanism 1 according to the real-time position of the excavation drum 21 on the guide rail. Since the two excavation drums 21 have different heights, the pitch angles of the dry mist nozzle 3 corresponding to them are also different, and after the guide rail moves relative to the hydraulic mechanism 1, the above pitch angle also needs to be adjusted accordingly.

[0041] The way to achieve horizontal angle adjustment is that the main control terminal also includes a horizontal angle adjustment module, and the horizontal angle adjustment module can adjust the horizontal angle of the dry mist nozzle 3 of the response hydraulic mechanism 1 according to the real-time position of the mining drum 21 on the guide rail.

[0042] The above system can be used to adjust the flow rate and angle of the dry mist nozzle 3 by the position of the excavation drum 21, which is different from the existing method, and can achieve better dust suppression and cooling effects. Compared with the existing fixed position spraying method, it is more intelligent.

[0043] As a preferred embodiment, on the basis of the above structure, the flow control method of the above dry mist nozzle 3 is as follows: the dry mist nozzle 3 is provided with two liquid inlets, and the diameters of the two liquid inlets are different, one of the liquid inlets is connected to the normally open main pipe through an independent solenoid valve, and the other liquid inlet is connected to the additional pipe through an independent solenoid valve. The normally open main pipe is the same as the existing water pipe and is in a normally open state to ensure the normal spraying of the dry mist nozzle 3. When the additional pipe is opened, the flow rate of the dry mist nozzle 3 can be increased without affecting other dry mist nozzles 3. It should be noted that the solenoid valve connected to the additional pipe is in a normally closed state, while the solenoid valve connected to the normally open main pipe is in a normally open state.

[0044] In order to utilize the flow critical value of the dry mist nozzle 3 to complete more operations, the atomization flow critical value of the dry mist nozzle 3 is preset to z, then the flow range of the dry mist nozzle 3 in the normally open main pipe is 0.6z-0.8z, and the flow in the additional pipe is z, and the normally open main pipe is in a normally open state, and the additional pipe is in a normally closed state. Therefore, under normal conditions, the conventional dry mist nozzle 3 sprays at a flow rate of 60% to 80%. After that, the normally open main pipe can control the solenoid valve to close after the hydraulic mechanism 1 is identified as responding to the hydraulic mechanism 1, and the additional pipe can open the solenoid valve. Correspondingly, the flow of the dry mist nozzle is the maximum spray flow at this time. At this time, the dust suppression effect is the best, and the overall system will not waste water flow. Most importantly, if the above two solenoid valves are opened at the same time, the atomized water flow can be converted into a liquid column water flow, which can be used to clean the equipment. This is not mentioned in the existing equipment, and the conventional choice is to set up additional cleaning equipment for cleaning.

[0045] Therefore, through the above method, after the hydraulic mechanism 1 is identified as being in response, the flow rate of the dry mist nozzle 3 can be greatly increased, and the dust suppression and cooling effects here can be ensured. If the spray effect of this flow rate is desired, under normal circumstances, the flow rate of the normally open main pipe needs to be adjusted to a very large value, so the water consumption of other dry mist nozzles 3 will be very high. Through the above method, the problem of increased water consumption caused by increasing the flow rate of all dry mist nozzles 3 at the same time can be further avoided.

[0046] A method for controlling a dry mist nozzle of an intelligent hydraulic mechanism uses the above-mentioned dry mist nozzle control system of an intelligent hydraulic mechanism and comprises the following steps:

[0047] S1. The response hydraulic mechanism 1 is identified. The main control terminal obtains the real-time coordinate of the mining machine on the guide rail as Q according to the encoder. Then the real-time coordinates of the two mining rollers 21 of the mining machine on the guide rail are Q+a and Qb, and a and b are the horizontal distances between the mining roller 21 and the center of the mining machine, and are preset values. After adjustment according to different working environments, the values ​​of a and b will also change accordingly. However, what remains unchanged is that the above values ​​are preset values, which can be directly obtained and will not change during the operation. Afterwards, according to the position of the hydraulic mechanism 1 relative to the guide rail, the three hydraulic mechanisms 1 closest to the two mining rollers 21 are identified as the response hydraulic mechanism 1;

[0048] And the specific method of identifying the responding hydraulic mechanism 1 is that in step S3, the total length of the preset guide rail is M, and the total number of the hydraulic mechanisms 1 is N, then the center coordinate values ​​of each hydraulic mechanism 1 arranged in sequence are M / 2N, 3*M / 2N, 5*M / 2N···(2N-1)*M / 2N, and the difference between the above center coordinate values ​​and Q+a and Qb can be obtained to obtain the IDs of the three hydraulic mechanisms 1 closest to the two mining drums 21 and identify them as the responding hydraulic mechanism 1, and when the distances between two hydraulic mechanisms 1 and the mining drum 21 are the same at the same time, the one with a larger ID value can be selected.

[0049] S2, the water volume is increased, the solenoid valve connected to the additional pipe in response to the hydraulic mechanism 1 in step S1 is opened, and the solenoid valve connected to the normally open main pipe is closed. Through the above method, the flow rate of the dry mist nozzle 3 at the position of the mining drum 21 can be significantly increased, but the flow rate of the dry mist nozzle 3 at other positions will not change at this time, and the above switching will not change the atomization effect of the water flow;

[0050] S3, horizontal angle adjustment, according to the real-time coordinates Q+a and Qb of the excavation drum 21 and the difference between the center coordinate values ​​of the response hydraulic mechanism 1, the horizontal deflection angle of the dry mist nozzle 3 is adjusted through the dual-axis adjustment platform 11;

[0051] The method for calculating the horizontal deflection angle is as follows: in step S3, the horizontal deflection angle of the dry mist nozzle 3 is preset to J, then tan(J)=X / Y, wherein X is the difference between the center coordinate value of the response hydraulic mechanism 1 and the real-time coordinate of the excavation drum 21, and Y is the difference in the distance between the dry mist nozzle 3 and the excavation drum 21 in the direction perpendicular to the length of the guide rail, ensuring that the spray range perfectly covers the position of the above-mentioned excavation drum 21, and can turn with the movement of the excavation drum 21 to achieve a tracking effect.

[0052] S4, pitch angle adjustment, according to the height difference between each excavating drum 21 and the guide rail, the pitch deflection angle of the dry mist nozzle 3 responding to the hydraulic mechanism 1 is adjusted through the dual-axis adjustment platform 11.

[0053] The method for calculating the pitch deflection angle is that in step S4, the pitch deflection angle of the dry mist nozzle 3 is preset to K, then tan(K)=Y / C, wherein C is the difference in vertical height between the dry mist nozzle 3 and the mining drum 21, and the distance between the dry mist nozzle 3 and the mining drum 21 in the vertical direction perpendicular to the length of the guide rail can be adjusted. Through the above method, the water mist position of the dry mist nozzle can be adjusted according to the actual height position of the mining drum 21 and the distance from the hydraulic mechanism 1, so as to ensure that the above dust suppression effect is optimal.

[0054] Under normal circumstances, after the coal mining machine 2 completes the operation, it needs to be cleaned, but the atomized water flow of the dry mist nozzle cannot complete the above operation, so it is necessary to set up additional cleaning equipment, or increase the overall flow rate. However, due to the long-term overload use of the dry mist nozzle, the atomization effect will deteriorate and even be damaged, and the short-term cleaning cannot complete the cleaning operation. Therefore, in order to clean the equipment, it also includes:

[0055] Step S5, cleaning operation: open the solenoid valve connected to the normally open main pipe and the solenoid valve connected to the additional pipe in the response hydraulic mechanism 1 at the same time. At this time, the overall flow rate is 160% to 180%. In this state, the dry mist nozzle sprays a liquid column, and as the coal mining machine 2 moves, the above-mentioned dry mist nozzle will switch to normal use after a short period of overload use, so it has little impact on the system.

[0056] In the above system, since the dry mist nozzle 3 changes from spraying to spraying a liquid column, in step S5, a first cleaning deflection angle T is preset, and when the two solenoid valves are opened at the same time, the horizontal deflection angle J of the responding hydraulic mechanism 1 is alternately deflected in two directions to the first cleaning deflection angle T. By moving the liquid column, a better cleaning effect can be obtained, and further on the basis of the above structure, in step S5, a second cleaning deflection angle U is preset, and when the two solenoid valves are opened at the same time, the pitch deflection angle K of the responding hydraulic mechanism 1 is alternately deflected in two directions to the second cleaning deflection angle U. In this way, liquid column cleaning operations can be performed within a certain range.
