The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figures 1-4 A preferred embodiment of the present invention provides a fixing structure for underground power supply cables in coal mines, comprising: a support frame 1 and a blocking device 3.

[0028] The support frame 1 has an accommodating space 2. The support frame 1 can be set in an arch shape or a "U" shape. Preferably, the support frame 1 is set in a "∩" shape. Its material is preferably metal, such as galvanized square steel. Secondly, due to the complex environment in the coal mine, the support frame 1 is preferably fixedly connected to the channel steel by threaded connection, so that it can be stably installed on the wall or ground by the channel steel.

[0029] The blocking devices 3 are all located in the accommodating space 2, dividing the accommodating space 2 into multiple cable unit accommodating slots 202. The blocking devices 3 are slidably connected to the support frame 1 (preferably with guide grooves, and the movable connection is achieved through the cooperation of the slider and the guide groove) to adjust the volume of the cable unit accommodating slots 202. The blocking devices 3 can be set into rectangular, triangular or irregular structures, preferably rectangular structures. At the same time, due to the harsh environment in the coal mine, the devices are easily corroded, so their material is preferably metal, such as galvanized steel.

[0030] In use, first place the power supply cable into the cable unit receiving groove 202, and then adjust the relative position of the blocking device 3 to change the size of the cable unit receiving groove 202 so that the cable unit receiving groove 202 can be adapted to the type or number of power supply cables currently placed in.

[0031] Obviously, the blocking device 3 can divide the accommodating space 2 into multiple cable unit accommodating slots 202 with different volumes, so as to install more power cables of different types or quantities and make full use of the accommodating space 2.

[0032] Preferably, in this embodiment, multiple blocking devices 3 are provided, and the multiple blocking devices 3 are distributed at intervals along the extension direction of the accommodating space 2. Setting multiple blocking devices 3 can form more cable capacity slots, thereby accommodating more cables and making full use of the empty accommodating space 2.

[0033] Preferably, in this embodiment, the support frame 1 has a cable inlet / outlet 201, and each cable unit receiving groove 202 is connected to the cable inlet / outlet 201; the cable inlet / outlet 201 is connected to a sealing member 4, which can open or close the cable inlet / outlet 201; this arrangement allows the cable to be installed in the cable unit receiving groove 202 without having to go along the groove depth direction, but only from the cable inlet / outlet 201 along the groove wall direction of the cable unit receiving groove 202. In this way, the old cable that has already been laid out can also slide directly into the cable unit receiving groove 202 along the cable inlet / outlet 201, without having to remove the end of the old cable and then pass it through the cable unit receiving groove 202, making the cable installation method more convenient and the practicality of the already laid-out cable higher.

[0034] Preferably, in this embodiment, in order to improve the overall capacity of a power supply cable fixing structure in a coal mine, multiple support frames 1 are provided, and the multiple support frames 1 are detachably connected in sequence. In two adjacent support frames 1, the side wall of one serves as the sealing member 4 of the other. Obviously, the side-by-side combination of the support frames 1 will form a new cable unit receiving groove 202, which can also accommodate cables.

[0035] Preferably, in this embodiment, to make the sliding process of the blocking device 3 on the support frame 1 smoother, the support frame 1 is provided with a first guide groove 101. The first guide groove 101 is located outside the accommodating space 2 and extends along the extending direction of the accommodating space 2. The blocking device 3 is provided with a first slider 301, which slides in cooperation with the first guide groove 101. With this configuration, the first slider 301 is located outside the accommodating space 2, and therefore will not be rubbed by the cable, preventing it from being stuck by the cable.

[0036] Preferably, in this embodiment, in order to further improve the smoothness of the sliding of the blocking device 3, one of the two adjacent support frames 1 is provided with a second guide groove 107, and the blocking device 3 in the accommodating space 2 of the other is provided with a second slider 305. The second guide groove 107 extends along the extension direction of the accommodating space 2, and the second slider 305 slides in cooperation with the second guide groove 107.

[0037] Preferably, in this embodiment, the support frame 1 includes a main frame 102 and a movable frame 103. The movable frame 103 is telescopically connected to the main frame 102 to adjust the volume of the accommodating space 2. The blocking device 3 includes a telescopically connected first segment plate 302 and a second segment plate 304. The first segment plate 302 is connected to and supported by the main frame 102. Adjacent support frames 1 are connected by the movable frame 103 (preferably detachable, but can also be fixed). This configuration allows the height of the accommodating space 2 to be adjusted according to the number of cables, making full use of external space and resulting in a more compact arrangement of multiple support frames 1 along the direction of gravity.

[0038] Obviously, since the support frame 1 can change the volume of the accommodating space 2 through different cooperation states of the main frame 102 and the movable frame 103, the barrier device 3 is set to be telescopically connected by the first segment plate 302 and the second segment plate 304. In this way, the barrier device 3, which can freely extend and retract, can adjust the size of the accommodating space 2. That is, the barrier device 3 can also divide the accommodating space 2 into cable unit accommodating slots 202 of different capacities, thereby meeting more complex and varied actual production needs.

[0039] Preferably, in this embodiment, the first slider 301 has a first bolt hole 303, and a first screw is connected to the first bolt hole 303 to lock the first slider 301 to the support frame 1; the second slider 305 has a second bolt hole 306, and a second screw is connected to the second bolt hole 306 to lock the second slider 305 to the support frame 1. This arrangement allows the first slider 301 and the second slider 305 to be locked by the frictional force between the first screw and the second screw and the support frame 1, respectively, preventing the first slider 301 and the second slider 305 from sliding under the lateral pressure of the cable.

[0040] Preferably, a clamping member 307 is provided between the slider and the screw, and a soft pad is provided between the clamping member 307 and the support frame 1. Obviously, when the screw is tightened, the distance between the clamping member 307 and the outer wall of the support frame 1 gradually shortens until the soft pad is tightly connected to the outer wall of the support frame 1, so that the slider is locked.

[0041] Preferably, in this embodiment, the main frame 102 has a plurality of first pin holes 104, which are distributed at intervals along the telescopic movement direction of the movable frame 103. The movable frame 103 has a second pin hole 106, which is used to match the first pin hole 104. The main frame 102 is provided with a pin 105 for simultaneously passing through the second pin hole 106 and one of the first pin holes 104.

[0042] In use, firstly, select the appropriate second pin hole 106 to match the first pin hole 104 according to the number of power supply cables, and adjust the length of the blocking device 3 as needed. Then, pass the power supply cable through the cable inlet and outlet 201 into the cable unit receiving groove 202 so that it is supported by the support frame 1. Then, slide the blocking device 3 to select the appropriate volume of the cable unit receiving groove 202, and then lock the first slider 301 and the second slider 305 to fix the cable.

[0043] Compared with the prior art, the beneficial effects of this utility model are as follows: The underground power supply cable fixing structure provided by this utility model can form more cable unit receiving grooves 202 with different volumes by changing the position of the blocking device 3 according to actual production needs. At the same time, the volume can be adjusted by changing the height of the cable unit receiving groove 202 through the blocking device 3 to accommodate different numbers of cables, thereby making full use of the overall capacity of the power supply cable fixing device.
