DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0041] Figure 1 According to an embodiment of the present application, a triangular coal automatic cutting system is shown. Figure 1 As shown, the triangular coal automatic machine cutting system includes: a centralized control center 100, a coal mining machine 200, a plurality of hydraulic supports 300 and a scraper conveyor 400.

[0042] The centralized control center 100 is in communication connection with the coal mining machine 200 and is used to issue coal mining instructions to the coal mining machine 200 .

[0043] The coal mining machine 200 is provided with a terminal 201, through which the coal mining machine 200 receives coal mining instructions, and the terminal 201 stores an automatic following-machine cutting application 2011 for triangular coal, and the coal mining machine 200 realizes automatic following-machine cutting of triangular coal based on the application 2011; two trigger point information are preset in the application 2011, namely the first trigger point information and the second trigger point information, and the trigger point is used to determine the following-machine stage of the coal mining process.

[0044] like Figure 2 As shown, the first trigger point is located near one end face of the working face 600, and when the coal mining machine 200 is located at the first trigger point, the coal mining machine 200 can cut the coal near one end face of the working face 600, and the second trigger point is located at a preset distance from the first trigger point, and the preset distance is greater than the length of the coal mining machine 200. The coal mining machine 200 operates according to the preset following stage and performs coal mining operations on the working face 600 during operation.

[0045] Further, in order to distinguish the two trigger points of another triangular coal working face, the trigger points of another triangular coal working face may be referred to as the third trigger point and the fourth trigger point.

[0046] The working face 600 is a coal face mined by the coal mining machine 200. The working face 600 includes a triangular coal working face 601 and a non-triangular coal working face 602. The triangular coal working face 601 is located on both sides of the working face 600, and the non-triangular coal working face 602 is located in the middle of the working face 600. The trigger point is located at the triangular coal working face. Further, the following stage includes:

[0047] The first follow-up stage: running from the non-triangular coal working face 602 to the second trigger point, and running from the second trigger point to the first trigger point;

[0048] The second follow-up stage: return from the first trigger point to the second trigger point;

[0049] The third follow-up stage: return from the second trigger point to the first trigger point;

[0050] The fourth following stage: running from the first trigger point to the non-triangular coal working face 602.

[0051] The scraper conveyor 400 is used to carry the coal shearer 200 and transport the coal cut by the coal shearer 200 .

[0052] A plurality of hydraulic supports 300 are used to push the scraper conveyor 400 to move toward the working surface 600 .

[0053] During operation, the centralized control center 100 first sends a coal mining instruction to the coal mining machine 200, and the coal mining machine 200 receives the coal mining instruction through the terminal 201 arranged therein; when the coal mining machine 200 receives the coal mining instruction, it obtains the automatic following machine cutting application, and runs the automatic following machine cutting application through the terminal 201, so that the coal mining machine 200 performs the coal mining operation according to the preset following machine stage; when the coal mining machine 200 is mining, the coal mining machine 200 will not only move left and right along the working face 600, but also needs to move toward the working face 600 in a direction perpendicular to the working face 600 because the coal is being cut.

[0054] In addition, because the scraper conveyor 400 is used to carry the coal mining machine 200 and transport the coal cut by the coal mining machine 200, the scraper conveyor 400 also needs to move in a direction perpendicular to the working surface 600, but the scraper conveyor 400 cannot move toward the working surface 600 by itself, and needs to be pushed by multiple hydraulic supports 300 to move the scraper conveyor 400 toward the working surface 600. Therefore, the actual working process is that multiple hydraulic supports 300 push the scraper conveyor 400 to move toward the working surface 600, so that the coal mining machine 200 carried on the scraper conveyor 400 moves toward the working surface 600.

[0055] When the coal mining machine 200 moves to the working face 600, the coal mining machine 200 cuts the coal on the triangular coal working face 601 on the working face 600 according to the above four following stages.

[0056] In addition, it should be noted that for the above-mentioned four following machine stages, the first following machine stage and the second following machine stage, although the coal of the triangular coal working face 601 is also cut, it is still a normal cutting operation, but this process is the first time that the coal mining machine 200 enters and exits the triangular coal area, and only the third following machine stage and the fourth following machine stage are the reciprocating movements of the triangular coal working face to thoroughly clean the triangular coal working face 601.

[0057] In addition, it should be noted that the above description only takes one triangular coal working face 601 of the working face 600 as an example, and the cutting of the second triangular coal working face is similar to that of the first triangular coal working face, which will not be described in detail here.

[0058] From the above content, it can be seen that the triangular coal automatic following machine cutting system shown in the embodiment of the present application has an automatic following machine cutting application stored on the terminal of the coal mining machine. When cutting the triangular coal working face, the automatic following machine cutting application only needs to go through four following machine stages to achieve the cutting of the triangular coal working face. Compared with the prior art, when the triangular coal area cannot be completely cut, it is no longer necessary to manually pull the hydraulic support multiple times. Instead, the following machine stage is determined according to the set trigger point, and automatic following is performed based on the following machine stage to achieve automatic cutting of the triangular coal working face, so as to save time and effort and improve cutting efficiency.

[0059] Alternatively, see Figure 3 The above trigger point can be set according to the position of the hydraulic support, that is, the position of the trigger point is consistent with the position of a certain hydraulic support.

[0060] For example, see Figure 3 The triangular coal automatic machine cutting system includes a total of 176 hydraulic supports, among which the 1st and 2nd are located in the tunnel, the 3rd to 31st hydraulic supports correspond to the first triangular coal working face, the 32nd to 145th correspond to the non-triangular coal working face, and the 146th to 174th correspond to the second triangular coal working face; the 175th and 176th are located in the tunnel.

[0061] Furthermore, for the first triangular coal working face, it includes a first trigger point and a second trigger point, wherein the first trigger point is the position corresponding to the 7th hydraulic support, and the second trigger point is the position corresponding to the 27th hydraulic support; for the second triangular coal working face, it includes a third trigger point and a fourth trigger point, wherein the third trigger point is the position corresponding to the 150th hydraulic support, and the fourth trigger point is the position corresponding to the 170th hydraulic support.

[0062] Further, see Figure 4 , Figure 4 Based on Figure 3 The hydraulic support shown in the figure determines the four following stages. Figure 4 As shown, assuming that initially, the coal mining machine 200 is located at the position of the 40th hydraulic support, the first following stage is that the coal mining machine 200 moves from the position of the 40th hydraulic support to the position of the 7th hydraulic support, the second following stage is that it moves from the position of the 7th hydraulic support to the position of the 27th hydraulic support, the third following stage is that it moves from the position of the 27th hydraulic support to the position of the 7th hydraulic support, and the fourth following stage is that it moves from the position of the 7th hydraulic support to the position of the 40th hydraulic support.

[0063] In addition, it should be noted that the pulling push rod and the pushing push rod described below cooperate with each other. The hydraulic support first needs to stretch out its push rod, that is, the pulling push rod described above, and then push the push rod forward. In this way, the scraper conveyor 400 can be pushed toward the working surface 600 by cooperating with each other.

[0064] Optionally, when the following machine stage is the first following machine stage, the coal mining machine 200 and the plurality of hydraulic supports 300 perform the following operations:

[0065] When the coal mining machine 200 moves forward to the position of a hydraulic support, it pulls the push rod of the nth hydraulic support behind it and pushes the push rod of the mth hydraulic support behind it, where n and m are both positive integers and m>n.

[0066] For example, see Figure 5 Assuming that initially, the coal mining machine 200 is located at the position of the 40th hydraulic support, and n=6, m=14, then the first following stage is that the coal mining machine 200 moves from the position of the 40th hydraulic support to the position of the 7th hydraulic support. When the coal mining machine 200 moves to the position of the 39th hydraulic support, it pulls the push rod of the 45th hydraulic support and pushes the push rod of the 53rd hydraulic support. When the coal mining machine 200 moves to the position of the 38th hydraulic support, it pulls the push rod of the 44th hydraulic support and pushes the push rod of the 52nd hydraulic support, and so on, until the coal mining machine 200 moves to the position of the 8th hydraulic support, it pulls the push rod of the 14th hydraulic support and pushes the push rod of the 22nd hydraulic support. In this way, when the coal mining machine 200 moves from the position piece of the 40th hydraulic support to the 7th hydraulic support, it pulls the push rods of the 14th to 45th hydraulic supports and pushes the push rods of the 22nd to 53rd hydraulic supports.

[0067] Optionally, when the following machine stage is the second following machine stage, the coal mining machine 200 and the plurality of hydraulic supports 300 perform the following operations:

[0068] Every time the coal mining machine 200 moves forward to the position of a hydraulic support, it pulls the push rod of the nth hydraulic support behind it until the push rods of the hydraulic support behind it are pulled out; when the coal mining machine moves to the second trigger point, it triggers the push rod of the hydraulic support behind it to perform a pushing operation at one time.

[0069] For example, still taking the above example, in the second following stage, the coal mining machine 200 starts to run from the 7th hydraulic support to the 27th hydraulic support. When the coal mining machine 200 is located at the 7th hydraulic support, it pulls the push rod of the 1st hydraulic support. When it moves to the 8th hydraulic support, it pulls the push rod of the 2nd hydraulic support. And so on. When it reaches the 19th hydraulic support, it pulls the push rod of the 13th hydraulic support. Since the push rods of the 14th to 45th hydraulic supports were pulled in the first following stage, when the coal mining machine 200 reaches the 19th hydraulic support, the 1st to 45th hydraulic supports have all been pulled; when the coal mining machine 200 continues to move, the coal mining machine 200 does not perform pushing and pulling operations until the coal mining machine 200 moves to the second trigger point, that is, when it moves to the position of the 27th hydraulic support, the push rods of the 1st to 27th hydraulic supports are pushed as a whole, so that the push rods of the 1st to 53rd hydraulic supports are all pushed.

[0070] Optionally, when the following stage is the third following stage, the coal mining machine 200 and the plurality of hydraulic supports 300 perform the following operations:

[0071] When the coal mining machine 200 moves forward n hydraulic supports from the second trigger point, the hydraulic support at the location of the second trigger point is pulled, and each time it moves forward to the location of a hydraulic support, the push rod of the rear nth hydraulic support is pulled.

[0072] For example, still taking the above example, in the third follow-up stage, the coal mining machine 200 moves from the position of the 27th hydraulic support to the position of the 7th hydraulic support. When the coal mining machine 200 starts to move from the position of the 27th hydraulic support to the position of the 22nd hydraulic support, the hydraulic support does not perform any operation. Until the coal mining machine 200 moves to the position of the 21st hydraulic support, the 27th hydraulic support is pulled, and when it moves to the position of the 20th hydraulic support, the 26th hydraulic support is pulled, and so on, until the coal mining machine 200 moves to the 8th hydraulic support, the 14th hydraulic support is pulled. Therefore, in the third follow-up stage, the operation of pulling the push rods of the 14th to 27th hydraulic supports is performed.

[0073] Optionally, when the following machine stage is the fourth following machine stage, the coal mining machine 200 and the plurality of hydraulic supports 300 perform the following operations:

[0074] Every time the coal mining machine 200 moves forward to the position of a hydraulic support, it pulls the push rod of the nth hydraulic support behind it until the push rod of the hydraulic support behind it is pushed; when the coal mining machine 200 moves to the second trigger point, it triggers the push rods of the m hydraulic supports behind it and away from the coal mining machine to perform the pushing operation at one time.

[0075] For example, still taking the above example, in the fourth following stage, the coal mining machine 200 moves from the position of the 7th hydraulic support to the position of the 27th hydraulic support. When the coal mining machine 200 is located at the position of the 7th hydraulic support, the push rod of the 1st hydraulic support is pulled. When it moves to the position of the 8th hydraulic support, the push rod of the 2nd hydraulic support is pulled. And so on, when the coal mining machine 200 moves to the position of the 19th hydraulic support, the push rod of the 13th hydraulic support is pulled; when the coal mining machine 200 continues to move forward, the hydraulic support does not perform the operation of pushing and pulling the push rod. When the coal mining machine 200 moves to the position of the 27th hydraulic support, the 1st to 13th hydraulic supports are triggered to push the push rods as a whole. When the coal mining machine 200 continues to move forward, each time the position of a hydraulic support is moved forward, the push rod of a hydraulic support is pushed.

[0076] In addition, it should be noted that the above-mentioned follow-up stage only applies to the triangular coal working face, and the non-triangular coal working face will not be described in detail here.

[0077] Alternatively, see Figure 6 The triangular coal automatic machine cutting system also includes a first camera 700, which is arranged at the coal mining site and is in communication connection with the centralized control center 100. The first camera 700 is used to obtain the coal mining video and send the coal mining video to the centralized control center 100.

[0078] It should be noted here that the first camera 700 is installed at the coal mining site and can capture the overall picture of the coal mining site to the greatest extent possible, so as to have a comprehensive understanding of the coal mining site.

[0079] Optionally, the first camera 700 may be one camera or multiple cameras. When multiple cameras are used, the images of the coal mining site can be captured more comprehensively.

[0080] Further, see Figure 6 The centralized control center 100 is provided with a display device 101, and the display device 101 is used to display the coal mining video.

[0081] After the display device 101 displays the coal mining video, the staff can view the situation of the coal mining site at any time. Further, the coal mining video can also be stored and played back through the display device when it is needed.

[0082] Alternatively, see Figure 7 The centralized control center 100 is provided with a control panel 102 , and the control panel 102 includes a start / stop button, which is used to start or stop the coal mining operation of the coal mining machine 200 .

[0083] A start / stop button is provided on the control panel 102 of the centralized control center 100, so that the staff can start or stop the coal mining machine conveniently.

[0084] Alternatively, see Figure 8 The triangular coal automatic following machine cutting system also includes a terminal device 500, which is separated from the centralized control center 100 and has a wireless connection. The terminal device 500 is used to control the coal mining machine 200 based on the centralized control center 100.

[0085] When the coal mining machine 200 is controlled by the terminal device 500 , the coal mining machine 200 can be controlled even when the terminal device 500 is at a certain distance from the coal mining machine 200 , thereby improving the convenience for the staff to operate the coal mining machine 200 .

[0086] Optionally, the triangular coal automatic machine cutting system further comprises an electro-hydraulic control system, which is used to control the state of the hydraulic support according to the automatic machine cutting application program.

[0087] Optionally, a second camera is provided on each hydraulic support, and the second camera is used to obtain the status of the hydraulic support in real time.

[0088] Optionally, a light source is provided on each hydraulic support, and the light source is used to illuminate the corresponding hydraulic support.

[0089] When a light source is provided on each hydraulic support, it helps the first camera 700 and the second camera to capture clearer images.

[0090] Optionally, the triangular coal automatic machine cutting system also includes an electronic device, which includes: one or more processors and a memory; the memory is used to store the triangular coal automatic machine cutting application, and the processor is used to obtain the triangular coal automatic machine cutting application from the memory and perform the triangular coal automatic machine cutting operation.

[0091] Optionally, the triangular coal automatic machine cutting system also includes a computer-readable storage medium, on which an automatic triangular coal following machine cutting application is stored. When the automatic triangular coal following machine cutting application is executed by the processor, the coal mining machine implements the automatic triangular coal following machine cutting operation.

[0092] Optionally, the triangular coal automatic machine cutting system also includes a computer program product, which includes a triangular coal automatic machine cutting application. When the triangular coal automatic machine cutting application is executed by a processor, the coal mining machine implements the triangular coal automatic machine cutting operation.
