Description

Technical Field

[0001] This invention relates to the field of coal mine working face conveying equipment technology, specifically to a self-moving cable collection device for underground coal mine working faces. Background Technology

[0002] In related technologies, underground coal mining generally adopts a reverse mining method, which involves first excavating the roadway and ventilation roadway to reach the planned mining area, and then advancing the mining equipment in reverse during mining. Within the roadway, mines often use a monorail to suspend the working face's cables. As the working face advances, the cables for the three main working machines become increasingly redundant, rapidly increasing their weight. Because the monorail is fixed to the roadway roof, there is a safety hazard during production due to roof deformation or corrosion and loosening of metal connectors, which could cause the monorail to detach. Furthermore, there is no safe location nearby to store lighting switches, commonly used tools, and other items. Summary of the Invention

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following description, with reference to the accompanying drawings, describes a self-moving cable collection device for underground coal mine working faces according to embodiments of the present invention. For example... Figures 1 to 8 As shown, the self-moving cable collection device for underground coal mine working faces according to an embodiment of the present invention includes at least one cable collection device 1 and a cable tray 7.

[0027] The cable collection device 1 includes a main frame 2, a moving device, and a cable platform 4. The moving device is mounted on the main frame 2 and is used to move the main frame 2 so that the cable collection device 1 can move with the coal mining face. The cable platform 4 is mounted on the main frame 2 and is used to hold the cables. The cable bracket 7 is used to hang the cables so as to cooperate with the cable collection device 1.

[0028] The cable platform 4 of the self-moving cable collection device for underground coal mine working faces according to an embodiment of the present invention is used to accommodate redundant cables or release cables, and the moving device can move with the progress of coal mining. Thus, during the continuous tunneling process of coal mining, the cable platform 4 can be used to retrieve and release cables, ensuring that the length of the released cable matches the required length of the equipment, and redundant cables can be stored within the cable platform 4. This eliminates the need for a hanging rail on the roadway roof, reducing the risk of cable detachment and improving construction safety. It eliminates the safety hazard of single-rail detachment in the original working method, while also providing storage space for working face lighting switches, commonly used tools, and other items.

[0029] Therefore, the self-moving cable collection device for underground coal mine working faces according to embodiments of the present invention facilitates cable delivery and retrieval, and improves construction safety.

[0030] like Figure 1As shown, in some embodiments, the self-moving cable collection device for underground coal mine working faces according to embodiments of the present invention further includes a self-moving tail section 8 of a belt conveyor and a belt conveyor 9, with the cable collection device 1 located between the self-moving tail section 8 and the belt conveyor 9. Specifically, the cable collection device 1 is located between the self-moving tail section 8 and the belt conveyor 9 in the extension direction of the roadway, without occupying additional space in the width direction of the roadway. The cable collection device 1 is adjacent to the self-moving tail section 8 of the belt conveyor, thereby being adjacent to the coal mining face, in order to collect the cables.

[0031] like Figure 6 As shown, in some embodiments, the main frame 2 is equipped with a conveying device for transporting coal, and the cable platform 4 is located above the conveying device. This allows the lower part of the cable collection device 1 to transport coal, while the upper part is the cable platform 4 for storing cables. Consequently, the coal on the self-propelled tail section 8 of the belt conveyor can be transported to the belt conveyor 9 via the conveying device on the cable collection device 1.

[0032] like Figure 6 As shown, in some embodiments, the conveying device includes an idler frame assembly 21 for supporting the belt. A conveyor belt is fitted onto the self-propelled tail section 8, the belt conveyor 9, and the idler frame assembly 21. This allows the self-propelled tail section 8, the belt conveyor 9, and the idler frame assembly 21 to jointly support and move the belt, so that the self-propelled tail section 8, the cable collection device 1, and the belt conveyor 9 can transport coal together.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the cable tray 7 includes a fixed tray 71 and a movable tray 72. The self-propelled tail section 8 of the belt conveyor is provided with a fixed support 81 and a movable support 82. The fixed tray 71 is located on top of the fixed support 81, and the top of the movable support 82 is provided with a slide rail 83. The movable support 82 is slidably mounted on the slide rail 83. Specifically, the length direction of the slide rail 83 is consistent with the length direction of the main frame 2, and the movable support 82 is located on the side of the self-propelled tail section 8 of the belt conveyor away from the cable collecting device 1.

[0034] The cable tray 7 is mounted on the self-propelled tail section 8 of the belt conveyor, allowing it to move along with the conveyor. Both the fixed tray 71 and the movable tray 72 support the cable, preventing it from sagging to the ground. The movable tray 72 accommodates changes in the length of the transfer conveyor's telescopic head, ensuring a smooth transition of the cable at the head. For example, multiple fixed trays 71 and movable trays 72 are provided, spaced apart along the length of the main frame 2.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments, there are multiple cable collection devices 1, which are connected sequentially along the length of the main frame 2. Specifically, adjacent cable collection devices 1 are connected by pins 22, thereby allowing multiple cable collection devices 1 to be connected in series, so that multiple cable platforms 4 can increase the cable capacity. For example, connecting frames are provided on both sides along the length of the main frame 2, and the connecting frames are provided with connecting holes. The connecting frames on two adjacent main frames 2 are connected by pins 22.

[0036] In some embodiments, the cable collection device 1 is located in the return air roadway or transport roadway of the working face so as to be adjacent to the coal mining face. For example, the self-moving tail section 8 of the belt conveyor, the cable collection device 1, and the belt conveyor 9 are located in the transport roadway.

[0037] In some embodiments, a fence 41 is provided around the cable platform 4. The fence 41 can be extended and retracted in the vertical direction, thereby adjusting the height of the fence 41 and thus adjusting the overall height of the cable collection device 1 to adapt to different tunnel heights.

[0038] like Figure 6 and Figure 7 As shown, in some embodiments, the cable platform 4 is connected to the main frame 2 via an adjustable frame 42, the length of which is adjustable in the vertical direction. The adjustable frame 42 includes a telescopic rod, or it includes multiple detachably connected supports. By adjusting the number of supports, the height of the adjustable frame 42 is adjusted, thereby adjusting the height of the fence 41, and thus the overall height of the cable collection device 1, adapting to different tunnel heights.

[0039] In some embodiments, at least one cable platform 4 is provided with a cable winding device for coiling cables, and the driving device of the cable winding device is at least one of a manual driving device, an electric driving device, and a hydraulic driving device. Specifically, the cable winding device is used for coiling cables for working faces such as coal mining machines and scraper conveyors. The driving device of the cable winding device includes, but is not limited to, handwheels, electric motors, and hydraulic motors. Thus, the cable winding device can be driven by human power, electrical energy, or hydraulic pressure as the driving force. For example, multiple cable platforms 4 are provided with multiple cable winding devices, and the driving devices of the multiple cable winding devices include manual driving devices and hydraulic driving devices.

[0040] For example, the drive unit of the cable winding device is a hydraulic motor, which consists of a hydraulic motor, a gear transmission pair, a drum, a support rotation mechanism, etc. By controlling the drive unit to drive the drum to rotate, redundant cables can be wound. For example, one or more cable winding devices are provided on multiple cable platforms 4.

[0041] In some embodiments, at least one cable platform 4 is provided with a cable bridging device. The bridging device consists of legs, cable hooks, etc., and is used for transition support of the cables between the transfer machine head and the self-propelled cable platform 4.

[0042] like Figures 4 to 8 As shown, in some embodiments, each cable collecting device 1 includes a wheel 52, a lateral movement device, and a lifting device. For example, both the lateral movement device and the lifting device are powered by the emulsion.

[0043] The lateral movement device includes a base frame 3 and a lateral movement drive device. The base frame 3 is located below the main frame 2 and can move relative to the main frame 2 in the width direction. The lateral movement drive device is connected to the main frame 2 and the base frame 3 and can drive the base frame 3 to move relative to the main frame 2 in the width direction.

[0044] like Figure 6 As shown, specifically, the lateral displacement drive device includes two lateral displacement hydraulic rods 31. The fixed part of the two lateral displacement hydraulic rods 31 is provided on the base frame 3. The telescopic part of the lateral displacement hydraulic rods 31 can extend and retract in the width direction of the main frame 2. The telescopic part of the two lateral displacement hydraulic rods 31 is connected to the main frame 2.

[0045] For example, the bottom connecting frames on the left and right sides of the main frame 2 are connected to the telescopic parts of two lateral hydraulic rods 31, which are arranged opposite to each other in the left-right direction. When the base frame 3 is in contact with the ground, one of the telescopic parts of the two lateral hydraulic rods 31 extends while the other retracts, so as to drive the main frame 2 to move relative to the ground in the left-right direction. After the main frame 2 is lifted by the lifting device and the base frame 3 is off the ground, one of the telescopic parts of the two lateral hydraulic rods 31 extends while the other retracts, so that the base frame 3 moves relative to the ground in the left-right direction and returns to its original position relative to the main frame 2.

[0046] like Figure 6 and Figure 7 As shown, each main frame 2 is provided with a lifting device on both sides in the width direction. The lifting device includes a lifting drive device and a wheel 52.

[0047] The lifting drive device is connected to the main frame 2. The lifting drive device can move the main frame 2 upwards to lift it off the ground, and it can also move the wheel 52 downwards. Therefore, when the cable collection device 1 needs to move, the lifting drive device moves the main frame 2 upwards and off the ground, and moves the wheel 52 downwards, allowing the cable collection device 1 to move. The lifting drive device cooperates with the lateral movement device to allow the cable collection device 1 to move in the width direction of the main frame 2.

[0048] In some embodiments, the lifting drive device includes a lifting hydraulic rod 5, the fixed part of which is connected to the main frame 2, and the telescopic part of which can extend downward. The bottom of the telescopic part of the lifting hydraulic rod 5 is connected to a wheel frame 51, and a wheel 52 is rotatably disposed within the wheel frame 51. A guide rail 53 is mounted on the bottom of the wheel frame 51. The wheel 52 is located above the corresponding guide rail 53. When the telescopic part of the lifting hydraulic rod 5 moves downward and the guide rail 53 contacts the ground, the wheel 52 engages with the guide rail 53, and the base of the guide rail 53 is located below the wheel frame 51.

[0049] Specifically, the wheel frame 51 has opposing limiting grooves 511 on both sides of the main frame 2 in the width direction. The upper surface of the guide rail 53 is an inverted V-shaped mating surface, and the upper surface of the guide rail 53 is inclined downward in the direction of both sides and mates with the surface of the wheel body 52. ​​The limiting grooves 511 of the wheel frame 51 allow the guide rail 53 to disengage downward from the wheel frame 51.

[0050] Therefore, when the telescopic part of the lifting hydraulic rod 5 retracts upward, the wheel frame 51 drives the wheel body 52 and the guide rail 53 to move upward and off the ground. At this moment, the lateral movement device can drive the main frame 2 to move. When the telescopic part of the lifting hydraulic rod 5 extends downward, the wheel frame 51 drives the wheel body 52 and the guide rail 53 to move downward. The guide rail 53 first contacts the ground, and then the wheel body 52 continues to move downward and contacts the guide rail 53. At the same time, it drives the main frame 2 to move upward and off the ground. At this moment, the main frame 2 and the lifting hydraulic rod 5 are a moving whole. The main frame 2 and the lifting hydraulic rod 5 can move on the guide rail 53 through the wheel body 52.

[0051] like Figure 4 As shown, the plurality of cable collection devices 1 include at least one pushing device that can drive the main frame 2 to move in its length direction. For example, the pushing device is powered by an emulsion.

[0052] Specifically, the moving device includes a moving hydraulic rod 6. One of the fixed part and the telescopic part of the moving hydraulic rod 6 is connected to a corresponding guide rail 53, and the other is connected to a corresponding main frame 2. Thus, after the main frame 2 moves upward and leaves the ground, the telescopic part of the moving hydraulic rod 6 extends and retracts, allowing the main frame 2 and the lifting hydraulic rod 5 to move on the guide rail 53 via the wheel 52, thereby moving the main frame 2 and the lifting hydraulic rod 5 relative to the ground. After the main frame 2 contacts the ground and the guide rail 53 leaves the ground, the telescopic part of the moving hydraulic rod 6 extends and retracts, causing the guide rail 53 to return to its original position.

[0053] When the cable collection device 1 moves, the lifting device and the pushing device are controlled by the electro-hydraulic control system. The guide rail 53 is lowered and the main frame 2 is raised. The pushing hydraulic rod 6 pushes the main frame 2 to move. Then the guide rail 53 is raised and the main frame 2 is lowered. The pushing hydraulic rod 6 pushes the guide rail 53 to reset and retract, and then completes one stroke.

[0054] For example, there may be multiple cable collection devices 1, each cable collection device 1 being equipped with a pushing device. Alternatively, multiple cable collection devices 1 may be equipped with multiple pushing devices, each pushing device capable of moving multiple cable collection devices 1.

[0055] According to an embodiment of the present invention, the self-moving cable collection equipment for underground coal mine working faces makes full use of the space above the belt conveyor (roadway) without occupying the width of the roadway. It integrates the intermediate frame of the belt conveyor with the material platform into one unit. In order to improve the adaptability of the working environment during the application process, it adds functions such as leveling, straightening, and self-moving. At the same time, the self-moving cable platform 4 is equipped with a cable winding device to facilitate cable winding and unwinding. This self-moving cable platform 4 can not only completely replace the original working method of using a single rail to drag the working face cable, but also improve the utilization rate of the limited space in the roadway.
