Description

Technical Field

[0001] The invention belongs to the technical field of automatic cable retraction and extension, and in particular relates to an automatic cable retraction and extension vehicle for coal mines. Background Art

[0002] In coal mining operations, electric mining equipment is a key tool for modern mining. Its efficient and stable operation is crucial to improving production efficiency and ensuring operation safety. In order to ensure that electric mining equipment continues to obtain power, cable retracting equipment is usually installed behind the mining equipment to achieve mechanized and automatic management of the cable.

[0003] In the related art, cable retracting and releasing equipment mostly adopts a single retracting and releasing wheel structure, which is responsible for retracting and releasing the cable along the entire path from the fixed power source to the mining equipment. However, in complex scenarios where the distance between the mining equipment and the power source changes dynamically, a single retracting and releasing wheel often makes it difficult to achieve precise control of the cable length, which not only affects the normal operation of the mining equipment, but also may cause safety hazards. Summary of the invention

[0004] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0005] In the process of coal mining, the cable retracting and releasing equipment generally adopts a single retracting and releasing wheel structure, which is responsible for the retracting and releasing of the cable from the fixed power supply point to the path required by the mining equipment when it moves throughout its operating area. This design does meet the cable management needs to a certain extent in the early stages of coal mining operations, ensuring that the mining equipment can obtain power supply and maintain its normal operation.

[0006] However, with the increasing complexity of mining environments and the diversification of mining equipment movement modes, the limitations of a single retractable wheel structure have gradually become apparent. In particular, in scenarios where the distance between mining equipment and power points changes frequently and drastically, a single retractable wheel is often unable to accurately adjust the length of the cable in real time according to the actual movement of the mining equipment.

[0007] When the cable length cannot accurately match the distance between the mining equipment and the power source, it may lead to unstable power supply, which in turn affects the performance and efficiency of the mining equipment. In addition, problems such as cable dragging and entanglement will also arise, which will not only increase the maintenance cost of the equipment, but also may delay the overall progress of the mining operation.

[0008] What’s more serious is that the cables are easily worn and damaged during the dragging process, increasing the risk of power outages. At the same time, overly long cables may become obstacles in the mining area, increasing the risk of accidents such as falls and equipment collisions. These safety hazards not only threaten the lives of operators, but may also have a serious impact on the production efficiency and reputation of coal mining companies.

[0009] To this end, an embodiment of the present invention proposes an automatic cable retracting vehicle for coal mines, which includes a vehicle frame, a winding assembly and a traveling assembly, wherein the traveling assembly is arranged at the bottom of the vehicle frame. The winding assembly includes a first reel, a second reel and a driver, wherein the first reel and the second reel are both rotatably connected to the vehicle frame, the first reel is used to retract the cable from the vehicle frame to the power source, the second reel is used to retract the cable from the vehicle frame to the mining equipment, and the driver is used to drive the first reel and the second reel to rotate to realize the retraction and release of the cable.

[0010] In summary, the coal mine cable automatic retractable vehicle provided by the embodiment of the present invention realizes the zoning management and precise control of the cable by introducing the independently operated first reel and second reel, which not only significantly improves the efficiency of cable retractable, but also effectively ensures the integrity and safety of the cable.

[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figures 1 to 10 As shown, an embodiment of the present invention provides a coal mine cable automatic retractable vehicle 100, which includes a vehicle frame 10, a traveling assembly 20 and a winding assembly 30, wherein the traveling assembly 20 is arranged at the bottom of the vehicle frame 10. The winding assembly 30 includes a first reel 31, a second reel 32 and a driver 33, wherein the first reel 31 and the second reel 32 are both rotatably connected to the vehicle frame 10, the first reel 31 is used to retract the cable from the vehicle frame 10 to the power source, the second reel 32 is used to retract the cable from the vehicle frame 10 to the mining equipment 200, and the driver 33 is used to drive the first reel 31 and the second reel 32 to rotate to realize the retraction and release of the cable.

[0044] Specifically, the driver 33 may include a first motor and a second motor, the first motor is used to drive the first drum 31, and the second motor is used to drive the second drum 32, so as to realize independent control of the first drum 31 and the second drum 32. The coal mine cable automatic retractable vehicle 100 provided by the embodiment of the present invention realizes the retraction and release of the cable through the independently operated first drum 31 and the second drum 32, which not only realizes the zoning management of the cable, but also greatly improves the efficiency and safety of the cable retraction and release. Figure 1During the use of the automatic cable retracting and releasing vehicle 100 shown in the figure, when the mining equipment 200 moves forward, the first reel 31 continuously releases the cable, and the second reel 32 adjusts the length of the cable between the vehicle frame 10 and the mining equipment 200, ensuring that the cable between the vehicle frame 10 and the mining equipment 200 is always in a suspended and taut state. When the mining equipment moves backward, the second reel 32 receives the cable between the vehicle frame 10 and the mining equipment, realizing the automatic retraction of the cable.

[0045] In summary, the coal mine cable automatic retractable vehicle 100 provided by the embodiment of the present invention realizes the zoning management and precise control of the cable by introducing the independently operated first reel 31 and second reel 32, which not only significantly improves the efficiency of cable retractable, but also effectively ensures the integrity and safety of the cable. This innovative design not only solves the limitations of existing cable retractable equipment in complex mining environments, but also provides a more reliable and efficient power guarantee for coal mining operations, and promotes the improvement of the automation and intelligent level of coal mine production.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the first drum 31 can accommodate a rubber-sheathed cable with a diameter of 57-60 mm and a length greater than or equal to 300 m, thereby ensuring that the mining equipment 200 can move freely in a wide range of operating areas while always maintaining a stable power supply. The second drum 32 can accommodate a rubber-sheathed cable with a diameter of 57-60 mm and a length greater than or equal to 100 m, which not only meets the dynamic adjustment requirements of the cable length of the mining equipment during operation, but also ensures that the cable between the frame 10 and the mining equipment always maintains an appropriate tension, avoiding safety hazards caused by cables that are too long or too short.

[0047] Furthermore, the coal mine cable automatic retractable vehicle 100 also includes a warning component, which includes a monitor and an alarm. The monitor is used to monitor the remaining number of turns on the first drum 31 and the second drum 32 and the remaining retractable length of the cable, and activate the alarm according to the remaining number of turns and the remaining retractable length, and control the operation of the driver 33, thereby achieving precise control of the cable retraction and release.

[0048] Specifically, when the monitor detects that the remaining number of turns is less than or equal to the preset turn threshold, the alarm is activated, and the driver 33 is controlled to stop running so that the cable stops being released. Optionally, the preset turn threshold can be set to 3 turns to 10 turns. In this embodiment, the preset turn threshold is set to 5 turns.

[0049] During the operation of the first reel 31, when the monitor detects that the remaining retractable length is less than or equal to the first preset length, the alarm is activated, and the driver 33 is controlled to stop running, and the cable is manually retracted to avoid excessive tension on the cable and damage to the cable connector at the power supply. Optionally, the first preset length can be set to 10m to 30m. In this embodiment, the first preset length is set to 20m.

[0050] During the operation of the second reel 32, when the monitor detects that the remaining retractable length is less than or equal to the second preset length, the alarm is activated, and the driver 33 is controlled to stop running and stop retrieving the cable. Optionally, the second preset length can be set to 20m to 40m. In this embodiment, the second preset length is set to 30m.

[0051] In some embodiments, the coal mine cable automatic retractable vehicle 100 further includes a torque detector, which is used to monitor the tension of the cable and control the operation of the driver 33 according to the tension data. The torque detector is used to monitor the tension of the cable and ensure that the tension of the cable is much smaller than the allowable tension of the cable. When the tension of the cable is close to the allowable tension of the cable, the driver 33 is controlled to stop running.

[0052] In addition, during the advancement of the automatic cable retracting and releasing vehicle 100 for coal mines, if the torque detector detects that the holding torque of the driver 33 on the second drum 32 is less than the pulling force of the cable on the second drum 32, the driver 33 is started to drive the second drum 32 to rotate and recycle the cable. Also, during the advancement of the automatic cable retracting and releasing vehicle 100 for coal mines, the pulling force of the cable on the first drum 31 increases. If the torque detector detects that the holding torque of the driver 33 on the first drum 31 is less than the pulling force of the cable on the first drum 31, the driver 33 controls the first drum 31 to rotate and gradually release the cable.

[0053] It should be noted that the process of the coal mine cable automatic retractable vehicle 100 moving toward the mining equipment is the forward process, and the process of the coal mine cable automatic retractable vehicle 100 moving away from the mining equipment is the backward process. During the backward process of the coal mine cable automatic retractable vehicle 100, the cable retraction and torque detection are opposite to the above forward process, and will not be repeated again.

[0054] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, in some embodiments, the automatic cable retracting and releasing vehicle 100 for coal mine cables includes an automatic cable arranging assembly 40, and the automatic cable arranging assembly 40 includes a guide rod 41, a screw rod 42, a cable arranging device 43 and a cable arranging motor 44. The guide rod 41 and the screw rod 42 are arranged side by side on the frame 10, and the screw rod 42 is rotatable relative to the frame 10. The cable arranging device 43 is threadedly connected to the screw rod 42, and the cable arranging device 43 is sleeved on the guide rod 41. The cable arranging motor 44 is used to drive the screw rod 42 to rotate to drive the cable arranging device 43 to move back and forth along the guide rod 41, so that the cable arranging device 43 moves at a uniform speed along the guide rod 41 to ensure that the cable reel is neatly placed, and the rotation speed of the cable arranging motor 44 can be adjusted according to different cable diameters to change the cable arranging speed.

[0055] Specifically, two automatic cable arranging assemblies 40 can be provided, and the two automatic cable arranging assemblies 40 are provided in one-to-one correspondence with the first reel 31 and the second reel 32. Taking the automatic cable arranging assembly 40 located on the first reel 31 as an example, the automatic cable arranging assembly 40 also includes two oppositely arranged support rods 45, and the support rods 45 can be fixed to the frame 10 by welding or bolting. The support rods 45 are located at the front side of the first reel 31, and the two ends of the guide rod 41 are correspondingly connected to the two support rods 45. Similarly, the two ends of the screw rod 42 are correspondingly connected to the two support rods 45. The cable arranging device 43 is provided with a first hole and a second hole, and the guide rod 41 is inserted into the first hole, and the screw rod 42 is inserted into the second hole. The cable arranging motor 44 is connected to the screw rod 42 in a transmission manner to drive the screw rod 42 to rotate, so that the screw rod 42 drives the cable arranging device 43 to move along the guide rod 41.

[0056] Furthermore, the automatic cable arrangement assembly 40 further includes at least two limiters 46, which are arranged on the frame 10 and are correspondingly arranged at both ends of the screw rod 42. The limiters 46 are used to monitor the moving position of the cable arrangement device 43 to achieve precise control of cable winding. Among them, the limiter 46 can be provided with a preset edge position. When the cable arrangement device 43 moves to the preset edge position of the limiter 46, it means that the cable on the first reel 31 or the second reel 32 has been wound to the edge, and the cable arrangement device 43 needs to move in the reverse direction to avoid damage to the cable due to excessive winding or cause safety hazards.

[0057] Optionally, the stopper 46 may be configured as a proximity sensor.

[0058] Furthermore, the automatic cable arrangement assembly 40 further includes an encoder 47, which is disposed on the screw rod 42 or the cable arrangement motor 44, and is used to monitor and record the position and moving direction of the cable arrangement device 43. When the cable arrangement device 43 stops moving, the encoder 47 can automatically record the position and moving direction of the cable arrangement device 43, ensuring that the moving direction is correct when restarting, and ensuring that the cable arrangement device 43 does not deviate from the predetermined trajectory when restarting, thereby avoiding various problems caused by the wrong direction.

[0059] In some embodiments, the cable arranger 43 has at least two guide frames 48, and two adjacent guide frames 48 are staggered in the height direction of the frame 10. The guide frame 48 is formed by splicing multiple rollers. A hollow cavity is provided in the guide frame 48. The hollow cavity is used for allowing one end of the cable to pass through and be wound onto the first reel 31 or the second reel 32, so that the cable can be more conveniently wound onto the first reel 31 or the second reel 32, reducing the wear of the cable.

[0060] In this embodiment, two guide frames 48 are provided, and the guide frame 48 close to the first reel 31 or the second reel 32 is named as the first frame, and the other guide frame 48 is named as the second frame. In the height direction of the frame 10, the first frame is higher than the second frame. It should be noted that at least three rollers are provided to enclose and form a hollow cavity. In this embodiment, four rollers are provided.

[0061] like Figure 6 As shown, in some embodiments, the automatic cable retracting and releasing vehicle 100 for coal mines further includes a guide assembly 50, which includes a support arm 51 and a roller group 52, one end of the support arm 51 is connected to the vehicle frame 10, and the other end of the support arm 51 is provided with a roller group 52. The roller group 52 is formed by splicing a plurality of rollers, and the roller group 52 has a through cavity for the cable to pass through. During the retracting and releasing process of the cable, the cable can move smoothly along the rolling surface of the roller group 52, avoiding friction and damage caused by direct contact with the vehicle frame 10 or other components. Similarly, when the cable is retracted, the roller group 52 can also ensure that it moves smoothly back to the first reel 31 or the second reel 32. And the support arm 51 can provide a reasonable bending radius for the cable retracting and releasing process, ensuring that the cable is always in the best state during the moving process. In some embodiments, the roller group 52 can be set to the same structure as the guide frame 48, which will not be repeated here.

[0062] Furthermore, the guide assembly 50 is provided with at least two groups, one of the two groups of guide assemblies 50 cooperates with the first reel 31, and the other of the two groups of guide assemblies 50 cooperates with the second reel 32. The support arm 51 in at least one group of guide assemblies 50 is rotatable relative to the frame 10 in the width direction of the frame 10, so that the support arm 51 can be rotated relative to the frame 10 in the width direction of the frame 10, thereby realizing flexible adjustment of the cable retraction angle, greatly improving the adaptability of the coal mine cable automatic retraction vehicle 100 to different working environments and cable specifications.

[0063] Specifically, during the cable recovery process, the position of the cable is inconsistent. The support arm 51 can rotate relative to the automatic frame 10 according to the position of the cable to adjust the position of the guide frame 48, thereby ensuring that the cable can be recovered along the best path, while also reducing cable wear.

[0064] Furthermore, the minimum distance between the roller set 52 and the frame 10 is 2 to 3 meters, thereby ensuring that the cable has enough space to stretch and contract naturally during the process of retracting and releasing, whether in a straight line or in a curved direction, and avoiding excessive squeezing or stretching due to a small space. In this embodiment, the minimum distance between the roller set 52 and the frame 10 is set to 2 meters.

[0065] like Figure 7 As shown, in some embodiments, the automatic coal mine cable retracting and releasing vehicle 100 also includes a clamping assembly 60, which includes a rotating frame 61, a clamping rod 62 and a pressure roller 63. The clamping rod 62 is connected to the rotating frame 61, and the pressure roller 63 is arranged at the end of the clamping rod 62 away from the rotating frame 61. The rotating frame 61 can rotate relative to the frame 10 to drive the pressure roller 63 to move, so that the pressure roller 63 is in contact with or separated from the first reel 31 or the second reel 32 to avoid loosening or slipping, thereby improving the stability and safety of the cable retraction.

[0066] Specifically, the frame 10 has a fixed frame 11, and the rotating frame 61 is rotatably connected to the fixed frame 11, thereby raising the height of the pressure roller 63, ensuring that the pressure roller 63 is located directly above the first reel 31 or the second reel 32, and ensuring that the cable is pressed. The pressing rod 62 is connected to the rotating frame 61, further raising the height of the pressure roller 63, so that the pressure roller 63 is always in contact with the cable during the process of the first reel 31 or the second reel 32 retracting and releasing the cable, which not only improves the stability of the cable retracting and releasing, but also ensures that the cable will not be subjected to any unnecessary damage during the retracting and releasing process.

[0067] Furthermore, the clamping assembly 60 also includes an elastic member 64, which is disposed between the clamping rod 62 and the rotating frame 61. The clamping rod 62 and the rotating frame 61 are rotatably connected, which not only ensures that the clamping rod 62 can maintain a stable posture during the rotation process, but also enables the pressure roller 63 to have a more uniform and moderate force when clamping the cable. In addition, during the process of cable retraction and release, the movement and winding of the cable often generate certain impacts and vibrations. The elastic member 64 can absorb these impacts and vibrations, ensuring that the clamping assembly 60 can remain stable and reliable when subjected to external forces.

[0068] Furthermore, the pressing assembly 60 further includes an adjustment motor 65, which is disposed on the frame 10 and is used to drive the rotating frame 61 to rotate. In actual applications, the operator can control the start and stop of the adjustment motor 65, as well as the rotation direction and angle of the rotating frame 61, by simple operation instructions. In this way, no matter how the diameter, length or working environment of the cable changes, the operator can ensure that the pressure roller 63 can always maintain a close fit with the cable by adjusting the drive of the motor 65 according to actual needs, thereby avoiding safety hazards caused by looseness or slippage.

[0069] In some embodiments, the coal mine cable automatic retractable vehicle 100 also includes a wireless remote control component, which is used to receive and transmit wireless signals and control the operation of the driver 33 according to the wireless signals. In practical applications, the introduction of wireless remote control components also brings higher safety and efficiency to coal mine operations. In a complex coal mine environment, operators often need to face various potential dangers and obstacles. The remote control function of the wireless remote control component enables operators to operate in a location away from dangerous areas, thereby effectively reducing the probability of accidents. At the same time, through precise remote control operations, operators can also complete the cable retraction and release operations more efficiently, improving overall work efficiency.

[0070] like Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, the walking assembly 20 includes a first track 21, a second track 22 and a driving wheel 23. The first track 21 and the second track 22 are arranged in parallel and spaced apart. The frame 10 is connected between the first track 21 and the second track 22. The driving wheel 23 is rotatably provided on the frame 10 and is used to drive the first track 21 and the second track 22 to rotate, thereby having excellent passability and climbing ability, ensuring the smooth progress of the cable retracting operation.

[0071] Furthermore, the frame 10 includes a plurality of cross bars 12, a plurality of vertical bars 13 and a bottom plate 14. The cross bars 12 and the vertical bars 13 are spliced ​​to form a frame, and the bottom plate 14 is laid on the frame, which not only provides sufficient strength and rigidity for the vehicle, but also provides reliable support for the installation and fixation of other components.

[0072] Furthermore, the frame 10 further includes a guardrail 15, which is arranged along the edge of the bottom plate 14 to prevent the vehicle from falling off or causing injuries to personnel due to bumps or collisions during driving. At the same time, the design of the guardrail 15 also takes into account the needs of easy observation and operation, ensuring that the operator can complete the work in a safe environment.

[0073] In specific implementation, the guardrails are usually made of high-strength steel pipes or alloy materials, and are finely polished and rust-proofed. Their shapes and sizes are customized according to the actual structure and operation requirements of the frame 10 to ensure the best protection and visual effects. In addition, the guardrails can also be firmly connected to the frame 10 by bolts or welding to ensure its stability and reliability during use.
