Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below, and it is obvious that the described embodiments are a part of the embodiments of the present application, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic diagram illustrating an automatic triangular coal cutting system according to an embodiment of the present application, where the automatic triangular coal cutting system, as shown in fig. 1, includes: a centralized control center 100, a coal mining machine 200, a plurality of hydraulic supports 300, and a scraper conveyor 400.

The centralized control center 100 is in communication connection with the coal mining machine 200 and is used for issuing coal mining instructions to the coal mining machine 200.

The coal mining machine 200 is provided with a terminal 201, the coal mining machine 200 receives a coal mining instruction through the terminal 201, the terminal 201 stores an automatic triangular coal following and cutting application program 2011, and the coal mining machine 200 realizes automatic triangular coal following and cutting based on the application program 2011; two pieces of trigger point information, namely, first trigger point information and second trigger point information, are preset in the application 2011, and the trigger points are used for determining a machine following stage of a coal mining process.

As shown in fig. 2, the first trigger point is located near an end surface of the working surface 600, and when the shearer 200 is located at the first trigger point, the shearer 200 can cut coal near the end surface of the working surface 600, the second trigger point is located at a preset distance from the first trigger point, the preset distance is greater than the length of the shearer 200, and the shearer 200 operates according to a preset machine following stage and performs a coal mining operation on the working surface 600 in operation.

Further, to distinguish the two trigger points of the other delta coal face, the trigger points of the other delta coal face may be referred to as a third trigger point and a fourth trigger point.

Wherein, working face 600 is the coal face of the coal mining of coal-winning machine 200, and working face 600 includes triangle coal working face 601 and non-triangle coal working face 602, and triangle coal working face 601 is located the both sides region of working face 600, and non-triangle coal working face 602 is located the middle zone of working face 600, and wherein, the trigger point is located triangle coal working face department, and further, includes in proper order with the quick-witted stage:

a first machine following stage: from the non-delta coal face 602 to the second trigger point, from the second trigger point to the first trigger point;

a fourth machine following stage: from the first trigger point, to the non-delta coal face 602.

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

The plurality of hydraulic supports 300 are used to propel the face conveyor 400 toward the work surface 600.

During operation, the centralized control center 100 firstly sends a coal mining instruction to the coal mining machine 200, and the coal mining machine 200 receives the coal mining instruction through a terminal 201 arranged in the coal mining machine 200; when the coal mining machine 200 receives a coal mining instruction, acquiring an automatic machine following and cutting application program, and operating the automatic machine following and cutting application program through the terminal 201, so that the coal mining machine 200 executes coal mining operation according to a preset machine following stage; when the shearer 200 is mining coal, the shearer 200 not only moves left and right along the working surface 600, but also needs to move toward the working surface 600 in a direction perpendicular to the working surface 600 because the coal is cut.

In addition, since the scraper conveyor 400 is used to carry the shearer 200 and to convey the coal cut by the shearer 200, the scraper conveyor 400 also needs to be moved in a direction perpendicular to the work surface 600, but the scraper conveyor 400 cannot be moved autonomously to the work surface 600 and needs to be pushed by a plurality of hydraulic supports 300 in order to move the scraper conveyor 400 to the work surface 600. Therefore, the actual operation is that the plurality of hydraulic supports 300 push the scraper conveyor 400 to move toward the work surface 600, thereby moving toward the work surface 600 using the shearer 200 carried on the scraper conveyor 400.

When the shearer 200 moves to the face 600, the shearer 200 cuts the coal on the delta coal face 601 on the face 600 in the four phases described above.

In addition, it should be noted that, for the four follow-up stages, the first follow-up stage and the second follow-up stage are still in normal cutting operation although the coal of the triangular coal face 601 is cut, but the process is that the shearer 200 enters and exits the triangular coal area for the first time, and only the third follow-up stage and the fourth follow-up stage are directed to the reciprocating movement of the triangular coal face to clean the triangular coal face 601 thoroughly.

In addition, it should be noted that, the above description only takes one triangle coal working face 601 of the working face 600 as an example, and the cutting of the second triangle coal working face is similar to that of the first triangle coal working face, and is not repeated herein.

Alternatively, referring to fig. 3, the trigger point may be set according to the position of the hydraulic support, that is, the position of the trigger point coincides with the position of a certain hydraulic support.

Illustratively, still referring to fig. 3, the delta coal automatic cutting system comprises 176 hydraulic supports in total, wherein the 1 st and 2 nd hydraulic supports are located in the roadway, the 3 rd to 31 th hydraulic supports correspond to the first delta coal face, the 32 nd to 145 th hydraulic supports correspond to the non-delta coal face, and the 146 th to 174 th hydraulic supports correspond to the second delta coal face; and 175 th stations and 176 th stations are positioned in the roadway.

Further, the first triangular coal working face comprises a first trigger point and a second trigger point, wherein the first trigger point is a position corresponding to the 7 th hydraulic support, and the second trigger point is a position corresponding to the 27 th hydraulic support; and the second triangular coal working surface comprises a third trigger point and a fourth trigger point, wherein the third trigger point is the position corresponding to the 150 th hydraulic support, and the fourth trigger point is the position corresponding to the 170 th hydraulic support.

Further, referring to fig. 4, fig. 4 shows four phases of the tracking according to the hydraulic support shown in fig. 3. As shown in fig. 4, assuming that the shearer 200 is initially located at the position of the 40 th hydraulic support, the first following stage is that the shearer 200 moves from the position of the 40 th hydraulic support to the position of the 7 th hydraulic support, the second following stage is that the shearer 200 moves from the position of the 7 th hydraulic support to the position of the 27 th hydraulic support, the third following stage moves from the position of the 27 th hydraulic support to the position of the 7 th hydraulic support, and the fourth following stage moves from the position of the 7 th hydraulic support to the position of the 40 th hydraulic support.

In addition, it should be noted that the following pulling pushing rod and pushing rod are mutually matched, the hydraulic support needs to stretch out the pushing rod, that is, the pulling pushing rod, and then push the pushing rod forward, so that the pushing rod and the pushing rod are mutually matched to push the scraper transporter 400 to the working surface 600.

Alternatively, when the following phase is the first following phase, the shearer 200 and the plurality of hydraulic supports 300 perform the following operations:

when the coal mining machine 200 moves forwards to the position of one hydraulic support, the pushing rod of the nth hydraulic support is pulled and the pushing rod of the mth hydraulic support is pushed, wherein n and m are positive integers, and m is greater than n.

For example, referring to fig. 5, assuming that initially the shearer 200 is located at the position of the 40 th hydraulic support, and n is 6 and m is 14, the first following phase is that the shearer 200 moves from the position of the 40 th hydraulic support to the position of the 7 th hydraulic support, when the shearer 200 moves to the position of the 39 th hydraulic support, the pusher jack of the 45 th hydraulic support is pulled and the pusher jack of the 53 th hydraulic support is pushed, when the shearer 200 moves to the position of the 38 th hydraulic support, the pusher jack of the 44 th hydraulic support is pulled and the pusher jack of the 52 th hydraulic support is pushed, and so on, until the shearer 200 moves to the position of the 8 th hydraulic support, the pusher jack of the 14 th hydraulic support is pulled and the pusher jack of the 22 th hydraulic support is pushed. In this way, during the process that the shearer 200 moves from the position piece of the 40 th hydraulic support to the 7 th hydraulic support, the pushing rods of the 14 th to 45 th hydraulic supports are pulled, and the pushing rods of the 22 nd to 53 th hydraulic supports are pushed.

Alternatively, when the following phase is the second following phase, the shearer 200 and the plurality of hydraulic supports 300 perform the following operations:

when the coal mining machine 200 moves forwards to the position of one hydraulic support, the pushing rod of the nth hydraulic support is pulled until the pushing rod of the hydraulic support is pulled out; when the coal mining machine moves to the second trigger point, the pushing rod of the hydraulic support behind the pushing rod is triggered to perform pushing operation at one time.

Illustratively, still taking the above example as an example, in the second follow-up stage, the shearer 200 starts to run from the 7 th hydraulic support to the 27 th hydraulic support, when the shearer 200 is located at the 7 th hydraulic support, the pushing rod of the 1 st hydraulic support is pulled, when the shearer moves to the 8 th hydraulic support, the pushing rod of the 2 nd hydraulic support is pulled, and the like, and when the shearer walks to the 19 th hydraulic support, the pushing rod of the 13 th hydraulic support is pulled. As the pushing rods of the 14 th to 45 th hydraulic supports are pulled in the first follow-up stage, when the coal mining machine 200 walks to the 19 th hydraulic support, all the 1 st to 45 th hydraulic supports are pulled; when the shearer 200 continues to move, the shearer 200 does not perform the push-pull operation until the shearer 200 moves to the second trigger point, that is, to the position of the 27 th hydraulic support, the push rods triggering the 1 st to 27 th tables are pushed as a whole, so that the push rods of the hydraulic supports of the 1 st to 53 th tables are all pushed.

Alternatively, when the following phase is the third following phase, the shearer 200 and the plurality of hydraulic supports 300 perform the following operations:

when the shearer 200 moves the n hydraulic supports forward from the second trigger point, the hydraulic support at the position of the second trigger point is pulled, and when the shearer moves forward to the position of one hydraulic support, the pushing rod of the nth hydraulic support at the back is pulled.

Illustratively, still taking the above example as an example, at the third follow-up stage, the shearer 200 moves from the position of the 27 th hydraulic support to the position of the 7 th hydraulic support, and when the shearer 200 moves from the position of the 27 th hydraulic support up to the position of the 22 nd hydraulic support, no operation is performed by the hydraulic supports. Until the 27 th hydraulic support is pulled when the shearer 200 moves to the position of the 21 st hydraulic support, the 26 th hydraulic support is pulled when the 20 th hydraulic support is moved, and so on, until the 14 th hydraulic support is pulled when the shearer 200 moves to the 8 th hydraulic support, and thus an operation of pulling the 14 th to 27 th hydraulic support pushing rods is performed in the third following stage.

Alternatively, when the following phase is the fourth following phase, the shearer 200 and the plurality of hydraulic supports 300 perform the following operations:

when the coal mining machine 200 moves forwards to the position of one hydraulic support, the pushing rod of the nth hydraulic support is pulled until the pushing rod of the hydraulic support is completed; when the shearer 200 moves to the second trigger point, the pushing rods that trigger the m hydraulic supports that are behind and far from the shearer perform the pushing operation at once.

Illustratively, still taking the above example as an example, in the fourth follow-up stage, the shearer 200 moves from the position of the 7 th hydraulic support to the position of the 27 th hydraulic support, when the shearer 200 is located at the position of the 7 th hydraulic support, the push rod of the 1 st hydraulic support is pulled, when the shearer 200 moves to the position of the 8 th hydraulic support, the push rod of the 2 nd hydraulic support is pulled, and so on, when the shearer 200 moves to the position of the 19 th hydraulic support, the push rod of the 13 th hydraulic support is pulled; when the coal mining machine 200 continues to move forwards, the hydraulic supports do not perform pushing and pulling operations on the pushing rods, when the coal mining machine 200 moves to the position where the 27 th hydraulic support is located, the 1 st to 13 th hydraulic supports are triggered to integrally push the pushing rods, and when the coal mining machine 200 continues to move forwards, the pushing rods of one hydraulic support are pushed every time the position of one hydraulic support is moved forwards.

In addition, it should be noted that the machine following stage is only for the triangular coal working face, and the details of the non-triangular coal working face are not described herein.

Further, still referring to fig. 6, the centralized control center 100 is provided with a display device 101, and the display device 101 is used for displaying the coal mining video.

After the display device 101 displays the coal mining video, the working personnel can check the situation of the coal mining site at any time. Furthermore, the coal mining video can be stored, and when the coal mining video needs to be viewed, the coal mining video is played back through the display device.
