[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0035] According to one embodiment of this application, a mobile cable bridging device is provided for raising cable 6. The mobile cable bridging device includes a moving unit 1, an adjusting unit 2, and a driving unit 3. The moving unit 1 supports the adjusting unit 2, and the driving unit 3 is mounted on the moving unit 1 and can drive the moving unit 1 to move. The adjusting unit 2 includes a mounting frame 21, a storage assembly 22, and a cable rod 23. The mounting frame 21 is detachably connected to the moving unit 1. The storage assembly 22 and the cable rod 23 are mounted on the mounting frame 21. The cable 6 is connected to the storage assembly 22, and the cable 6 is laid on the end of the cable rod 23 away from the mounting frame 21. The cable reel 221 of the storage assembly 22 is rotatably mounted on the mounting frame 21. When the storage assembly 22 rotates in a first direction, it stores the cable 6. When the storage assembly 22 rotates in a second direction, it releases the cable 6. The first direction and the second direction are opposite in rotation direction.

[0036] like Figures 1 to 3 As shown, the moving unit 1 has a support frame, and the adjusting unit 2 and the driving unit 3 are both mounted on the support frame. In this embodiment, the driving unit 3 is an engine, which provides power to the moving unit 1, enabling the moving unit 1 to move forward, backward, and / or turn, thereby facilitating the movement of the mobile cable bridging device and effectively reducing the labor intensity of manual operations.

[0037] The adjustment unit 2 is used to store and release the cable 6, and adjust the length and height of the cable 6 from the ground. This not only prevents the cable 6 from piling up on the ground during use, thus preventing damage caused by vehicles or movement, but also allows the release length of the cable 6 to be adjusted through the storage component 22 of the adjustment unit 2 to adapt to the cable 6 layout requirements of different sites, thereby improving the adaptability of the mobile cable bridge device.

[0038] The mounting bracket 21 of the adjustment unit 2 is mounted on the support frame of the mobile unit 1, and the storage component 22 is connected to the support frame of the mobile unit 1 through the mounting bracket 21. When the engine drives the mobile unit 1 to move, the storage component 22 located on the support frame can move accordingly, so that when the position of the mobile cable bridge device is changed, the length of the cable 6 can be adjusted at the same time. This prevents the cable 6 from being too long and accumulating on the ground, causing crushing and wear, and also prevents the cable 6 from being too short and being pulled apart.

[0039] The cable pole 23 is a height-adjustable telescopic pole. The bottom of the cable pole 23 is connected to the mounting frame 21, and the cable 6 is laid on top of the cable pole 23. By setting the cable pole 23 to elevate the cable 6, the cable 6 is laid above the road, which not only avoids the cable 6 being crushed and damaged when laid on the ground, but also allows the height of the cable 6 to be adapted to vehicle passage by adjusting the height of the telescopic pole, preventing the cable 6 from being too low and affecting vehicle traffic, thus effectively improving the adaptability of this mobile cable bridging device.

[0040] The storage assembly 22 is rotatably connected to the mounting bracket 21. A power unit drives the storage assembly 22 to rotate in a first direction, enabling it to store the cable 6. The power unit also drives the storage assembly 22 to rotate in a second direction, allowing it to release the cable 6. The first direction is clockwise rotation of the storage assembly 22. The second direction is counter-clockwise rotation of the storage assembly 22.

[0041] When the storage component 22 rotates in the first direction, it can store the cable 6. For example, when the road width narrows and the adaptability of the mobile cable bridging device needs to be adjusted, the length of the cable 6 needs to be shortened. By storing the cable 6 through the clockwise rotation of the storage component 22, the extended length of the cable 6 is shortened, which can reduce the possibility of damage to the cable 6 caused by it being crushed due to accumulation on the ground. When the storage component 22 rotates in the second direction, it can release the cable 6. For example, when the road width increases, or when the height of the cable 6 needs to be increased to allow taller vehicles to pass, the length of the cable 6 needs to be increased. By releasing the cable 6 through the counterclockwise rotation of the storage component 22, the extended length of the cable 6 is increased, which can accommodate wider roads or the cable bridging height for taller vehicles.

[0042] The storage component 22 can be stored or released by means of winding, coiling, etc.

[0043] Of course, the storage component 22 in this embodiment is not limited to the structure described above, and those skilled in the art can configure it according to actual needs. For example, the first direction is counterclockwise, and the second direction is clockwise.

[0044] In this embodiment, the adjustment unit 2 and the drive unit 3 are mounted on the moving unit 1. The drive unit 3 provides power to the moving unit 1, which in turn drives the moving unit 1 to move the adjustment unit 2, thereby adjusting the position of the mobile cable bridging device and effectively reducing manual labor intensity. The cable reel 221 rotates in the first direction to store the cable 6, and rotates in the second direction (opposite to the first direction) to release the cable 6. The storage component 22 is rotatably connected to the mounting frame 21 to adjust the unfolded length of the cable 6 to adapt to different scenario requirements. The cable pole 23 elevates the cable 6, which not only facilitates the passage of vehicles of different heights under the cable 6 but also reduces damage to the cable 6 caused by crushing, effectively improving the adaptability of the mobile cable bridging device. The mounting frame 21 is detachably connected to the moving unit 1 to support the storage component 22, facilitating the inspection and replacement of parts and effectively reducing maintenance costs.

[0045] In one example, the mounting bracket 21 has two opposing rotating shafts 213, which are rotatably connected to opposite ends of the cable reel 221. The cable reel 221 has a receiving cavity, and a conductive slip ring 222 is provided in the receiving cavity. The conductive slip ring 222 is in signal communication with the cable 6 wound on the cable reel 221. The cable reel 221 rotates about the axis of the cable reel 221 in both the first direction and the second direction.

[0046] like Figures 1 to 3 As shown, the cable reel 221 is cylindrical and has retainers at opposite ends along the axial direction. The cable 6 is wound on the cable reel 221, and the retainers prevent the cable 6 from slipping out of the cable reel 221 along the axial direction.

[0047] The two ends of the cable reel 221 are respectively connected to the rotating shaft 213. The power unit can drive the cable reel 221 to rotate in the first direction or the second direction to store or release the cable 6, thereby adjusting the unfolded length of the cable 6 and preventing the cable 6 from being crushed and damaged when it is piled up on the ground during movement.

[0048] The cable reel 221 has a receiving cavity. The shape of the receiving cavity is adapted to the conductive slip ring 222. The conductive slip ring 222 is embedded in the receiving cavity. By setting the conductive slip ring 222 in the cable reel 221, the conductive slip ring 222 is connected to the cable 6, so that the cable 6 wound on the cable reel 221 can communicate with the outside through the conductive slip ring 222.

[0049] like Figures 1 to 3As shown, the cable reel 221 is cylindrical, with its opposite ends along the axial direction connected to the rotating shaft 213. The power unit provides power to the cable reel 221, enabling it to rotate around its own axis. When the cable reel 221 rotates clockwise, the storage assembly 22 stores the cable 6, reducing its unfolded length to prevent it from being crushed and damaged by piling up on the ground. When the cable reel 221 rotates counterclockwise, the storage assembly 22 releases the cable 6, increasing its unfolded length to adapt to different road heights or widths, thus improving the adaptability of this mobile cable bridging device.

[0050] Of course, the first and second states in this application embodiment are not limited to the above-described situations, and those skilled in the art can set them according to actual needs. For example, the first state can be releasing cable 6, and the second state can be storing cable 6.

[0051] In one example, the storage assembly 22 further includes a junction box 223, which is disposed on the mounting bracket 21 and is connected to the conductive slip ring 222.

[0052] like Figures 1 to 3 As shown, the conductive slip ring includes a stationary part and a rotating part. The rotating part of the conductive slip ring is connected to the cable reel, while the stationary part remains stationary as the cable reel rotates. The conductive slip ring is connected to the cable on the cable reel, and the stationary part of the conductive slip ring is connected to the junction box. The conductive slip ring connects the cable on the cable reel to the junction box, facilitating the connection of external equipment.

[0053] The junction box 223 on the mounting bracket 21 serves to connect the cable 6, facilitating wiring and ensuring stable and reliable connection. The conductive slip ring 222 is installed inside the drum and provides electrical conductivity.

[0054] In one example, the cable pole 23 is a telescopic pole with adjustable height.

[0055] like Figures 1 to 5 As shown, the cable pole 23 is a height-adjustable telescopic pole. The bottom of the cable pole 23 is connected to the mounting frame 21, and the cable 6 is laid on top of the cable pole 23. By setting the cable pole 23 to elevate the cable 6, the cable 6 is laid above the road, which not only avoids the cable 6 being crushed and damaged when laid on the ground, but also allows the height of the cable 6 to be adapted to vehicle passage by adjusting the height of the telescopic pole, preventing the cable 6 from being too low and affecting vehicle traffic, thus effectively improving the adaptability of this mobile cable bridging device.

[0056] In one example, the end of the cable pole 23 away from the mounting bracket 21 is provided with a guide wheel 231 and a limiting member 232. The guide wheel 231 is rotatably disposed at the end of the cable pole 23, and the cable 6 is laid in the guide groove of the guide wheel 231. The limiting member 232 is connected to the cable pole 23 and forms a limiting channel with the guide wheel 231 to limit the position of the cable 6 in the guide groove.

[0057] like Figures 1 to 3 As shown, the cable pole 23 is an adjustable telescopic pole. The bottom of the cable pole 23 is connected to the moving unit 1. The height of the cable pole 23 can be adjusted according to site requirements to accommodate vehicles of different heights traveling together.

[0058] The top of the cable pole 23 has a limiting member 232, which includes two rectangular plates disposed on the top of the cable pole 23. The two rectangular plates are arranged opposite each other and are rotatably connected to opposite sides of the guide wheel 231, allowing the guide wheel 231 to rotate. The guide wheel 231 has a guide groove, and the cable 6 is laid in the guide groove. When adjusting the length of the cable 6, the friction of the cable 6 can be reduced by the rotating guide wheel 231, making it easier to adjust the length of the cable 6.

[0059] The limiting component 232 also includes a housing, which is fan-shaped or semi-circular. The center of the housing is connected to a rectangular plate, and the guide wheel 231 is located inside the housing. The housing and the guide wheel 231 form a limiting channel. The cable 6 passes through the limiting channel. The guide wheel 231 and the housing limit each other to block the cable 6 and prevent the cable 6 from slipping out of the guide groove when the guide wheel 231 moves, which would cause the cable 6 to detach from the guide wheel 231 and affect the length adjustment effect of the cable 6.

[0060] In one example, the mobile cable bridging device further includes a wire rope winch 4, which is mounted on the mounting frame 21, and the wire rope on the wire rope winch 4 is connected to the cable 6 passing through the limiting member.

[0061] like Figures 1 to 3 As shown, a wire rope winch 4 is also installed on the mounting frame 21. The wire rope on the wire rope winch passes around the top of the cable pole 23 and connects to the cable 6, which is used to fix the winch and prevent unnecessary cable slack.

[0062] A wire rope winch 4 is typically equipped with a winch, which is a cylindrical shaft used to secure the wire rope. The winch is connected to an electric motor or manual operating device via a transmission mechanism such as gears, chains, or belts, thus enabling its rotation. The wire rope, connected to the cable 6, is wound around the winch. As the winch rotates, the wire rope winds or unwinds, thereby raising or lowering or moving the cable 6 horizontally. The wire rope winch 4 is usually equipped with a braking device to secure the winch and prevent unnecessary cable slack. The braking device can be controlled manually or automatically to ensure the wire rope winch 4 remains stable and safe when not in operation.

[0063] In this embodiment, the wire rope winch 4 is driven by a drive unit 3. The drive unit 3 is an engine, which drives the wire rope winch 4 to rotate, thereby raising and lowering the cable 6.

[0064] In one example, the mobile cable bridging device further includes a counterweight 5, which is disposed on the mobile unit 1, and the mounting frame 21 is detachably connected to the counterweight 5.

[0065] like Figures 1 to 3 As shown, the counterweight 5 can be a discarded mine car tire, etc., and is set on the mobile unit 1. By setting the counterweight 5 on the mobile unit 1, the center of gravity of the mobile cable bridging device is lowered, effectively improving the stability of the mobile cable bridging device during the bridging process.

[0066] By detachably connecting the counterweight block 5 to the mobile unit 1, the counterweight of the mobile cable bridging device can be increased according to different scenario requirements, thereby improving the adaptability of the mobile cable bridging device.

[0067] The bottom of the cable pole 23 is detachably connected to the moving unit 1. By detachably connecting the cable pole 23 to the moving unit 1, it is easy to replace the telescopic pole with one that is suitable for different height scenarios.

[0068] Of course, the cable rod 23 in this embodiment is not limited to the structure described above, and those skilled in the art can configure it according to actual needs. For example, the bottom of the cable rod 23 can be connected to the counterweight 5.

[0069] In one example, the mounting bracket 21 includes a connecting part 211 and a supporting part 212, which are arranged sequentially from bottom to top. The counterweight 5 is embedded in the connecting part 211, and the connecting part 211 is detachably connected to the moving unit 1 and the counterweight 5 respectively.

[0070] like Figures 1 to 3As shown, the mounting frame 21 is a metal frame mounted on the moving unit 1. This frame is used to strengthen the connection between the moving unit 1, the counterweight 5, and the storage assembly 22. The frame has a connecting part 211 and a supporting part 212. The connecting part 211 is located below the supporting part 212 and has a connecting space. The bottom of the connecting part 211 is connected to the moving unit 1, and the counterweight 5 is embedded in the connecting space. The mounting frame 21 is connected to the moving unit 1 and the counterweight 5 by bolts or other connectors, thereby fixing the adjusting unit 2 to the moving unit 1. This allows the cable 6 to be wound up and down through the storage assembly 22 of the adjusting unit 2 during the movement of the mobile cable bridge device, reducing damage such as crushing caused by the cable 6 accumulating on the ground due to untimely winding and unwinding during the movement.

[0071] By detachably connecting the mounting bracket 21 to the moving unit 1 and the counterweight 5, it is possible to perform maintenance or replacement operations on the components of the mobile cable bridge device, which not only effectively reduces equipment maintenance costs, but also effectively reduces the difficulty of maintenance and replacement operations.

[0072] The bottom of the cable pole 23 is connected to the mounting frame 21, the counterweight 5 and the moving unit 1, which improves the connection strength of the cable pole 23 and prevents the mounting frame 21 or the counterweight 5 from loosening and affecting the support strength of the cable pole 23. Moreover, by connecting the cable pole 23 to the moving unit 1, the support height of the cable pole 23 can be accurately determined, reducing the impact of different counterweight 5 weights or mounting frame 21 height on the accuracy of the cable 6 support.

[0073] like Figures 1 to 3 As shown, the mounting bracket 21 has a support portion 212 for supporting the storage component 22.

[0074] The support part 212 is a metal frame, and pivots are provided on opposite sides of the support part 212 so that when the storage component 22 is installed on the support part 212, it can be rotatably connected to the support part 212 through the pivots, so as to store or release the cable 6 and adjust the length of the cable 6.

[0075] The storage assembly 22 can be cylindrical, and the cable 6 is wound around it. When the cable 6 needs to be stored, the storage assembly 22 is driven to rotate in a first direction by a power element; when the cable 6 needs to be released, the storage assembly 22 is driven to rotate in a second direction by a power element. The first and second directions are opposite. For example, the first direction is clockwise rotation, and the second direction is counterclockwise rotation.

[0076] In one example, the mobile unit 1 includes a tracked chassis 11, and the drive unit 3 is disposed on the tracked chassis 11, the drive unit 3 driving the tracked chassis 11 to move.

[0077] likeFigures 1 to 3 As shown, the mobile unit 1 includes a tracked chassis 11, which drives the counterweight 5 and the adjustment unit 2 to move, thereby adjusting the position of the mobile cable bridging device. The tracked chassis 11 is driven by the drive unit 3, enabling it to provide a walking function. The drive unit 3 is an engine.

[0078] By adopting a tracked chassis 11, the mobile cable bridging device can move smoothly in mining areas with complex terrain, thus improving its adaptability.

[0079] Of course, the moving unit 1 in this embodiment is not limited to the structure described above, and those skilled in the art can configure it according to actual needs. For example, a structure such as a tire can also be used to drive the counterweight 5 and the adjusting unit 2 to move.

[0080] According to another embodiment of this application, a cable bridging system for a mining area road is provided, which includes at least two mobile cable bridging devices as described above, with the two mobile cable bridging devices disposed on both sides of the road.

[0081] like Figures 1 to 5 As shown, two mobile cable bridging devices are set up on both sides of the road. The cable 6 is stored or released according to the road width. When the cable 6 needs to be stored to prevent it from being too long, the storage component 22 is in the first state, which can effectively prevent the cable 6 from piling up on the ground and being crushed and damaged. When the cable 6 needs to be released to prevent it from being too short, the storage component 22 switches to the second state, releasing the cable 6 appropriately and increasing its length so that it is suspended above the road. The height of the cable pole 23 is adjusted according to the height of the vehicles passing through the road section so that the cable 6 is elevated to avoid affecting the passing vehicles.

[0082] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
