Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for rail transit equipment, and specifically to a cable retracting and extending trailer device for rail traveling equipment. Background Art

[0002] Under the background that rail traveling equipment is widely used in scenarios such as tunnel construction, coal mine operation, and municipal maintenance, in order to ensure the mobile power supply or signal continuity of the equipment, the cable retracting and extending device, as an important part of its auxiliary facilities, has become an indispensable part of the system integration of such equipment. Especially in a rail system with a long moving distance or a round-trip operation mode, how to achieve the synchronous retraction and extension of the cable during the movement of the equipment is one of the key technologies to ensure the stable operation of the system.

[0003] Traditional cable follow-up systems mostly rely on fixed guiding, free winding, or mechanical driving forms to achieve cable management. Such structures could meet the basic requirements to a certain extent under the early technical conditions, especially under the conditions of a relatively simple environment and stable operating conditions of the equipment, and could achieve a limited degree of orderly cable layout. However, with the continuous increase in the operation frequency of rail traveling equipment, the complexity of the operation path, and the improvement of the requirements for reliability and safety, a series of problems in the cable retracting and extending process of the traditional solution have become increasingly prominent, becoming a technical shortcoming restricting the improvement of system performance.

[0004] The existing technology cannot fully match the cable retracting and extending rhythm with the traveling speed of the equipment, easily leading to phenomena such as cable tensioning, sagging, or piling up, and further causing mechanical failures such as knotting, winding, and abrasion. This not only affects the operation efficiency but may also cause serious consequences such as cable breakage and equipment shutdown. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a cable retracting and extending trailer device for rail traveling equipment, which solves the problems such as easy winding, overheating, pollution, and unstable tension control of the cable in the cable retracting and extending trailer device.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A cable retracting and deploying trailer device for an orbital traveling device, comprising a plurality of connectors connected in series through a towing device. Both ends of the towing device are provided with track wheels. The top of one of the connectors is installed with an orbital traveling device body. The top of one of the connectors is fixedly connected with a cable pipeline for positioning the cable and connecting it to the orbital traveling device body. The outer wall of one of the track wheels is installed with a driving gear. The top of one of the connectors is fixedly connected with a support frame. The inner wall of the support frame is rotatably connected with a cable reel. The outer wall of the cable reel is fixedly connected with a toothed ring to complete the cable retracting and deploying synchronously with the rotation direction of the track wheel. The inner wall of the support frame is rotatably connected with a rotating rod. The outer wall of the rotating rod is fixedly connected with a first gear and a scroll fan. One end of the support frame is provided with an air outlet. One end of the support frame is provided with a cleaning component. One end of the support frame is installed with a buffer component.

[0007] Preferably, the first gear is meshed with the toothed ring, and the toothed ring is meshed with the driving gear.

[0008] Preferably, a plurality of heat dissipation holes are formed on the outer surface of the cable reel, and the heat dissipation holes correspond to the air outlet.

[0009] Preferably, the buffer component includes an anti-abrasion block fixedly connected to one end of the support frame. A pressing rod is slidably connected inside the anti-abrasion block. A spring is sleeved on the outer wall of the pressing rod. An adjusting roller is rotatably connected inside the pressing rod.

[0010] Preferably, one end of the spring is fixedly connected to the inner wall of the anti-abrasion block and applies a downward pressure to the pressing rod.

[0011] Preferably, the buffer component includes a through box fixedly connected to one end of one of the connectors. A rotating shaft is rotatably connected to the inner wall of the through box. A worm is fixedly connected to the outer wall of the rotating shaft. A brush ring is rotatably connected to the inner wall of the through box. A worm gear is fixedly connected to the outer wall of the brush ring. A plurality of brush heads are installed on the inner wall of the brush ring.

[0012] Preferably, both ends of the rotating shaft are fixedly connected with second belt pulleys, which are connected by a belt to the first belt pulleys fixed at both ends of the rotating rod.

[0013] Preferably, a plurality of air inlet filters are provided at one end of the support frame.

[0014] Preferably, the scroll fan is rotatably connected to the inner wall of the support frame, and together with the air inlet filter and the air outlet, a wind channel is formed.

[0015] Preferably, the tooth ratio of the first gear to the toothed ring is 1:30 - 1:60, and the tooth ratio of the driving gear to the toothed ring is 1:20 - 1:40.

[0016] Working principle: When the staff uses the cable retracting and deploying device of this track walking equipment, first connect one end of the cable to the track walking equipment body through the cable pipeline, and complete the series connection between the trailers through the towing device.

[0017] After the series connection is completed, the track walking trailer can be pushed or driven forward as required. The rotation of the track wheels drives the meshing between the driving gear and the tooth ring arranged outside the cable reel, so as to realize the cable retracting and deploying effects during the forward or backward movement, and avoid the reduction of the service life caused by cable knotting.

[0018] Since the track walking equipment is mostly used in environments such as coal mines or underground tunnels, during the use of the cable, it is inevitable that dust or other sundries will be adsorbed by static electricity on the outside of the cable, which will increase the friction during the cable retracting and deploying process, resulting in cable breakage; in order to avoid this situation, whether it is cable deployment or retraction, during the rotation of the cable reel, the rotation of the rotating rod is driven through the meshing connection with the first gear, and then through the belt power transmission between the first pulley and the second pulley, so as to drive the worm on the rotating shaft to mesh with the worm gear rotating on the outer wall of the brush ring inside the box, and then realize the forward or reverse rotation of the brush ring, so as to cooperate with multiple groups of annular brush heads in the brush ring to complete the scraping and cleaning of the outer wall of the passing cable, thereby improving the overall service life.

[0019] In addition, since the operating environment is generally relatively high, and the cable does not dissipate heat actively when in a disk shape, there will be a situation where the bottom layer of the cable is at a high temperature during the cable retracting and deploying process. In order to reduce the adverse effects of high temperature on the cable, when the first gear is driven to rotate, the vortex fan will be synchronously driven to rotate inside the inner wall of the support frame, and then through the air duct constructed by the air inlet filter screen and the air outlet, continuous heat dissipation will be carried out on the cable inside the cable reel, and the air circulation will be improved through air cooling, thereby reducing the high temperature risk.

[0020] Moreover, since the cable line is relatively long, in order to avoid the situation where the externally released cable is stuck and the cable tension is too large, resulting in breakage, in order to improve the buffering, when the cable is externally released, it will first pass through the bottom of the adjusting roller and bypass the outer wall of the anti-abrasion block, and finally be discharged through the box. In the case of low tension, the spring is used to push the adjusting roller to press down the spring, so as to ensure that the cable between the adjusting roller and the cable reel is always straightened. And when the external tension of the cable is large, the transmitted force will first straighten and lift the adjusting roller, thereby increasing the transmission resistance, thus realizing buffering and improving the detection time of the staff, and reducing the adverse effects caused by too large or too small tension.

[0021] The present invention provides a cable retracting and deploying trailer device for a track walking equipment. It has the following beneficial effects:

[0022] 1. Through the cooperation of the heat dissipation holes on the cable reel with the air duct system, the air outlet, and the vortex fan, the present invention realizes continuous heat dissipation of the cable during the winding and unwinding process, prevents damage caused by excessive cable temperature, effectively reduces the high-temperature risk of the cable, thereby avoiding the aging of the cable insulation material or the fracture of the cable due to excessive temperature, and ensuring the safe operation of the equipment.

[0023] 2. The present invention realizes real-time adjustment of the cable tension through the anti-abrasion block and the adjustment roller via a spring, which can effectively avoid the fracture of the cable caused by excessive tension during the winding and unwinding process. The buffer assembly automatically adjusts according to the real-time tension of the cable, ensuring that the cable is always in an appropriate tension state, thereby reducing the risk of cable damage and avoiding accidents or failures caused by excessive stretching of the cable.

[0024] 3. Through the cooperation of the worm, the brush ring, the brush head, and the rotating rod, the present invention realizes real-time cleaning of the outer wall of the cable, removes dust and impurities electrostatically adsorbed on the cable surface, obtains the effect of reducing friction and wear, thereby extending the durability of the cable, avoiding damage to the cable caused by external debris, and maintaining the good performance of the cable.

[0025] 4. Through the meshing connection of the track wheel, the driving gear, and the external tooth ring of the cable reel, the present invention realizes the stable and smooth operation of the cable during the winding and unwinding process, avoids cable knotting or entanglement, obtains the effect of neat winding and unwinding of the cable, thereby effectively extending the service life of the cable and reducing equipment failures and maintenance costs caused by cable entanglement.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, the present invention provides a cable retracting and extending trailer device for a track walking device, including a plurality of connectors 5 connected in series through a trailer 2. Track wheels 3 are arranged at both ends of the trailer 2. The top of one of the connectors 5 is installed with the main body 1 of the track walking device. The top of one of the connectors 5 is fixedly connected with a cable pipeline 4 for positioning the cable and connecting it to the main body 1 of the track walking device. A driving gear 9 is installed on the outer wall of one of the track wheels 3. The top of one of the connectors 5 is fixedly connected with a support frame 6. A cable reel 7 is rotatably connected to the inner wall of the support frame 6. A toothed ring 8 is fixedly connected to the outer wall of the cable reel 7 to complete the cable retracting and extending in synchronization with the rotation direction of the track wheel 3. A rotating rod 12 is rotatably connected to the inner wall of the support frame 6. A first gear 11 and a scroll fan 13 are fixedly connected to the outer wall of the rotating rod 12. An air outlet 10 is installed at one end of the support frame 6. The first gear 11 is meshed with the toothed ring 8, and the toothed ring 8 is meshed with the driving gear 9. A plurality of heat dissipation holes 15 are formed on the outer surface of the cable reel 7, and the heat dissipation holes 15 correspond to the air outlet 10. A plurality of air inlet filters 16 are arranged at one end of the support frame 6. The scroll fan 13 is rotatably connected to the inner wall of the support frame 6, and together with the air inlet filter 16 and the air outlet 10, a air duct is formed.

[0035] Specifically, multiple connectors 5 are connected in series through a trailer hitch 2, and track wheels 3 are provided on each connector 5. The track wheels 3 not only provide support for the entire system but also ensure that the trailer can move smoothly on the track. A track walking device body 1 is installed on the top of each connector 5, enabling the cable to be firmly connected and positioned, ensuring that the position of the cable in the track device remains stable at all times. The positioning of the cable is completed through a cable conduit 4, which plays a guiding role and is connected to the track walking device body 1, keeping the cable fixedly connected to the device body.

[0036] The winding and unwinding of the cable are achieved through the cooperation of the track wheels 3 and the drive gear 9. The track wheels 3 drive the drive gear 9 to rotate, and the drive gear 9 meshes with the toothed ring 8 on the outer wall of the cable reel 7, synchronizing the rotation of the cable reel 7 through the gear drive system. The meshing of the drive gear 9 with the toothed ring 8 ensures that the cable can be wound and unwound smoothly when the device moves forward or backward. With this design, the cable will not be entangled due to improper operation, and the winding and unwinding process is very stable, avoiding the common problem of cable knotting in traditional devices.

[0037] The support frame 6 is the core support component of the entire device. A cable reel 7 is rotatably connected to the inner wall of the support frame 6. The toothed ring 8 on the outer wall of the cable reel 7 meshes with the first gear 11, ensuring that the reel rotates stably during the cable winding and unwinding process, ensuring the uniformity and neatness of the cable winding and unwinding. The rotating rod 12 on the inner wall of the support frame 6 forms an auxiliary heat dissipation mechanism through connection with the turbine fan 13. The rotating rod 12, through cooperation with the gear system, causes the turbine fan 13 to rotate, and a duct system is constructed through the air inlet filter 16 and the air outlet 10 to help the cable dissipate heat effectively during the winding and unwinding process.

[0038] To prevent the cable from being damaged due to overheating during the winding and unwinding process, multiple heat dissipation holes 15 are designed on the outer surface of the cable reel 7. These heat dissipation holes 15 correspond to the air outlet 10, ensuring that hot air is discharged through the duct, reducing the cable temperature and minimizing cable insulation aging or cable breakage caused by excessive temperature. This design is particularly important, especially when the device is used in high-temperature or enclosed environments, effectively extending the service life of the cable.

[0039] To ensure the cleanliness of the cable during the winding and unwinding process and reduce friction, multiple air inlet filters 16 are provided at one end of the support frame 6. They can filter dust and impurities in the outside air, preventing excessive dust from adhering to the cable surface. The turbine fan 13 drives air flow through rotation, cooperating with the filter system to further enhance air circulation, helping to keep the cable surface clean and achieving effective heat dissipation. In this way, the operating stability of the cable can be ensured after long-term operation.

[0040] Please refer to the appendix Figure 4 - appendix Figure 5, the buffer assembly includes an anti-abrasion block 14. The anti-abrasion block 14 is fixedly connected to one end of the support frame 6. A pressing rod 25 is slidably connected inside the anti-abrasion block 14. A spring 27 is sleeved on the outer wall of the pressing rod 25. An adjusting roller 26 is rotatably connected inside the pressing rod 25. One end of the spring 27 is fixedly connected to the inner wall of the anti-abrasion block 14 and applies a downward pressure to the pressing rod 25. The gear ratio of the first gear 11 to the toothed ring 8 is 1:30 - 1:60, and the gear ratio of the driving gear 9 to the toothed ring 8 is 1:20 - 1:40.

[0041] Specifically, the buffer assembly includes an anti-abrasion block 14 provided at one end of the support frame 6. The anti-abrasion block 14 itself is a fixed structure, providing a stable installation foundation. A pressing rod 25 is connected inside it in a sliding manner. The pressing rod 25 can achieve a certain stroke of sliding adjustment in the vertical direction. A spring 27 is sleeved on its outer wall, which is used to apply a constant downward elastic force to the pressing rod 25, so as to continuously and flexibly press the cable. One end of the spring 27 is fixedly connected to the inner wall of the anti-abrasion block 14, and the other end presses on the outer wall of the pressing rod 25 to form a pre-tightening force, making it have certain buffer and rebound characteristics. The existence of the elastic force can effectively absorb the impact generated by the cable due to inertia or irregular tension during operation, ensure the flexibility of the cable operation, and avoid system damage caused by sudden tensile force fluctuations.

[0042] An adjusting roller 26 is rotatably connected inside the pressing rod 25. This roller, as a component in contact with the cable, can rotate along the running direction of the cable when the cable passes by, reducing the relative friction between the cable and the buffer assembly, and further avoiding skin scratches or local stress concentration. This structure ensures that the cable can maintain the necessary pressing effect during operation without being subject to hard interference. The self-adaptive rotation characteristic of the adjusting roller 26, combined with the dynamic pressure provided by the spring 27, enables the entire buffer structure to have good compliance and dynamic response capabilities, and can work effectively under different operating speeds or environmental conditions.

[0043] From the perspective of the transmission ratio design, to ensure the controllability and matching of the rotation speed of the cable reel 7, the gear ratio between the first gear 11 and the toothed ring 8 in the present invention is 1:30 to 1:60. This ratio setting is obtained through experiments and parameter optimization, which can make the cable reel 7 rotate slowly and stably under the drive of the driving gear 9, avoiding the cable getting out of control or uneven winding due to too high a rotation speed. A larger gear ratio means that the cable reel 7 can obtain sufficient output torque at a lower input rotation speed, which is beneficial to maintaining smooth operation when the load is large or the environment changes.

[0044] Meanwhile, the gear ratio between the driving gear 9 and the gear ring 8 is set between 1:20 and 1:40. This gear ratio relationship ensures that when the track wheel 3 moves forward or backward with the whole vehicle, the gear system can efficiently transmit power to the winch system. The gear ratio range is adjusted to adapt to the operating requirements of different track-running equipment at different speeds, with a certain degree of adaptability and engineering practicability. As the input source of the entire power chain, the driving gear 9 is reasonably matched with the gear ring 8, which can avoid transmission shock or gear knocking, and improve the stability and service life of the entire system operation.

[0045] Please refer to the attached Figure 4 - attached Figure 5 The impurity removal component includes a through box 17, which is fixedly connected to one end of one of the connectors 5. A rotating shaft 20 is rotatably connected to the inner wall of the through box 17. A worm 21 is fixedly connected to the outer wall of the rotating shaft 20. A brush ring 22 is rotatably connected to the inner wall of the through box 17. A worm gear 23 is fixedly connected to the outer wall of the brush ring 22. A plurality of brush heads 24 are installed on the inner wall of the brush ring 22. Both ends of the rotating shaft 20 are fixedly connected with second belt pulleys 19, which are connected to the first belt pulleys 18 fixed at both ends of the rotating rod 12 through a belt.

[0046] Specifically, this component includes a through box 17 arranged at one end of one of the connectors 5. The through box 17 is a closed structure and is integrally fixed to the end of the connector 5 by mechanical connection. Its internal space is designed to accommodate the cleaning transmission component and provide structural protection for it. A rotating shaft 20 is arranged on the inner wall of the through box 17, and the rotating shaft is rotationally supported by a bearing component to ensure its stable operation.

[0047] A worm 21 is fixedly connected to the outer wall of the rotating shaft 20 for forming a transmission fit with the driving structure of the cleaning brush ring 22. The corresponding one is the brush ring 22, which is rotatably connected to the inner wall on the other side of the through box 17, and a worm gear 23 is fixedly connected to its outer wall. The worm 21 and the worm gear 23 form a standard worm drive structure, which has a self-locking characteristic and can achieve stable and slow torque output. This structural design can effectively control the rotation speed of the brush ring 22, avoid impact friction on the cable surface by the brush heads 24, and enhance the flexibility and controllability of cleaning.

[0048] A plurality of brush heads 24 are evenly arranged on the inner wall of the brush ring 22. The brush heads 24 are made of materials with strong wear resistance and moderate flexibility, which can fit the outer wall of the cable and continuously clean its surface. During the operation of the cable, the cable passes through the inner ring of the brush ring 22, and the brush heads 24 are distributed around the cable and slowly rotate with the brush ring 22 to gently friction-clean the cable, removing impurities such as dust, water vapor, and oil stains attached to the surface, and effectively delaying the insulation aging and loss of the cable caused by pollution.

[0049] To achieve power transmission, second pulleys 19 are provided at both ends of the rotating shaft 20, and are connected to the first pulleys 18 fixed at both ends of the rotating rod 12 through a synchronous belt, forming a belt drive system. The rotation of the cable reel 7 drives the synchronous rotation of the rotating rod 12, and then drives the rotation of the rotating shaft 20 and the worm 21 thereon through the pulleys and the belt, and finally drives the rotation of the worm gear 23 to make the brush ring 22 operate. This transmission path does not rely on an additional motor, and reduces the energy consumption and system complexity by using the linkage principle of the original mechanism.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
