Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile power supply technology, in particular to a towline trolley device. BACKGROUND

[0002] The overhead traveling crane, commonly known as the overhead crane, is a key equipment for material handling in modern industrial production. In order to provide power for the movable trolley on the overhead traveling crane, a towline carrying system is needed to manage and support the power supply cable moving with the trolley, which usually contains multiple trolley units connected in series through connecting pieces and rolls along the track fixed on the bridge. The power supply cable is segmented and fixed on each trolley unit. When the trolley runs, it pulls the first trolley and drives all subsequent trolleys to move synchronously on the track through the connecting pieces, thereby ensuring that the cable can smoothly follow the extension or contraction of the trolley and continuously supply power.

[0003] However, the above-mentioned existing towline carrying system has significant defects. Since multiple trolley units and their connecting pieces form a complex series structure, their reliability is closely related to the state of the rolling guide wheels of each trolley unit and the connecting pieces. In actual operation, the guide wheels of the trolley are prone to blockage due to dust accumulation, wear and tear, or mechanical damage, or the connecting pieces may break due to fatigue, overload, etc. Once a trolley is stuck and cannot move, or the connecting piece is disconnected, the pulling force generated by the moving trolley will directly act on the fixed power supply cable. This can easily cause the cable to be forcibly pulled and worn, twisted, or even completely torn. Cable breakage not only causes the overhead traveling crane to lose power and be unable to use, forcing production to be interrupted, but also requires high cost and long time to replace the entire power supply cable, which seriously affects production efficiency and equipment availability. In addition, in order to prevent such failures, frequent manual inspections are required, increasing maintenance workload and cost. Therefore, there is an urgent need for a more reliable towline trolley solution that prevents cable damage caused by local blockage or breakage. SUMMARY

[0066] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0067] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0068] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0069] Overhead cranes, also known as gantry cranes, are core equipment for modern industrial material handling. They are three-dimensional motion devices that span over workshops, move longitudinally along factory tracks via end beams, and move laterally along the lower flange tracks of the main beam via lifting trolleys, achieving lifting and lowering of lifting devices. They are widely used in metallurgy, manufacturing, warehousing, and other fields. The cable-stayed trolley system that powers its moving trolley often operates in harsh industrial environments characterized by dust, drastic temperature and humidity fluctuations, and mechanical vibration. Existing tandem guide wheel trolley systems are vulnerable in such environments: dust easily intrudes, causing guide wheel jamming and abnormal track wear; the chains or cables connecting the trolley units are also prone to wear, fatigue, and even breakage due to continuous traction, vibration, impact, and corrosion. If a single trolley unit jams or a connector fails, the tension of subsequent moving units will directly act on the fixed power cable section, easily causing major failures such as forced pulling, twisting, and even breakage of the cable. This not only directly leads to crane system paralysis and production process interruption, but also results in high costs and time-consuming repairs for replacing the entire towing cable, severely impacting production efficiency and equipment availability. Furthermore, to prevent such failures, frequent manual inspections at high altitudes are necessary to check the condition of guide wheels, the integrity of connectors, and the condition of the track, resulting in a large workload and high safety risks. Therefore, for the power supply requirements of this critical equipment, bridge cranes, there is an urgent need to develop a new towing cable trolley technology solution that can significantly reduce mechanical friction and wear points, effectively resist the effects of dusty environments, and possess fault isolation capabilities to prevent local failures from triggering a global chain reaction. This would fundamentally improve the reliability and environmental adaptability of the system and significantly reduce the maintenance burden and risks.

[0070] See Figure 1 The diagram shows a structural schematic of a cable-stayed trolley device according to an embodiment of this application, comprising:

[0071] The transport system includes a track assembly, a trolley assembly, and a tow cable assembly.

[0072] The trolley assembly is connected to the track assembly, and the towing cable assembly is connected to the trolley assembly;

[0073] The cleaning system is located on the transportation system;

[0074] The early warning system is installed on the transportation system.

[0075] In the above embodiment, the transport system consists of a track assembly, a trolley assembly, and a tow cable assembly. The trolley assembly is fixed to the track assembly via connection points, while the tow cable assembly is directly attached to the trolley assembly, forming a stable moving structure. Both the cleaning system and the early warning system are integrated into the transport system. The cleaning system is responsible for removing dust, and the early warning system monitors the operating status. All components work together to ensure smooth trolley movement.

[0076] This structure avoids direct contact between the traditional guide wheels and the track, reducing mechanical friction points. Utilizing magnetic levitation, the trolley assembly suspends on the track assembly, significantly reducing the risk of jamming. Simultaneously, the integrated cleaning and early warning system enhances overall reliability, makes it suitable for dusty environments, extends equipment lifespan, and reduces maintenance requirements.

[0077] See Figure 2 and Figure 3 The diagram shows a schematic representation of the track assembly provided in an embodiment of this application. Further, the track assembly includes:

[0078] Support frame 1, which has a right-angled structure, is used to fix the trolley to the overhead crane;

[0079] The trolley track 2 is connected to the end of the support frame 1. The trolley track 2 is made of non-magnetic material and has a square structure with an opening in its cross section.

[0080] The first fixing bolt 3 is located at the connection between the support frame 1 and the trolley track 2.

[0081] In the above embodiment, the support frame 1 adopts a right-angle structure, and its end is fastened to the trolley track 2 by the first fixing bolt 3 to ensure overall stability. The trolley track 2 is made of non-magnetic material and has an open square cross-section, which facilitates the installation and adjustment of internal components. The height of the support frame 1 can be adapted to different travel conditions, and the non-magnetic material design avoids magnetic field interference.

[0082] This connection method provides a robust supporting foundation, preventing track deformation or displacement. The non-magnetic material ensures the stability of the magnetic levitation, preventing magnetic interference from affecting the trolley's operation. The right-angle structure simplifies the installation process, improves site adaptability, and reduces installation time and costs.

[0083] Furthermore, the track assembly also includes:

[0084] Guide rail 4, there are two guide rails 4, located at both ends of the opening of the trolley track 2;

[0085] Guide rail groove 5 is formed on guide rail 4;

[0086] The first magnet base 6, there are two of them, and they are connected to the side of the guide rail 4 where the guide rail groove 5 is not opened;

[0087] The first magnet 7 is located on the first magnet base 6, with its positive pole facing away from the first magnet base 6.

[0088] In the above embodiment, the track assembly includes two parallel guide rails 4 located on both sides of the opening of the trolley track 2. Each guide rail 4 has a guide rail groove 5 for guiding the movement of the cleaning system. A first magnet base 6 is mounted on the guide rail 4 and connected to the ungrooved side of the guide rail 4. A first magnet 7 is fixed to the base with its positive pole facing upward, forming the basis for magnetic levitation.

[0089] This configuration achieves stable levitation of the trolley through the synergistic effect of the guide rail groove 5 and the magnet. The guide rail groove 5 assists in the movement of the dustproof device to prevent dust from entering; the positive pole of the first magnet 7 faces upward to generate a repulsive force, reducing the physical contact between the trolley and the track, thereby reducing wear and the probability of jamming, and improving the durability of the system in harsh environments.

[0090] See Figure 4 The diagram shows a structural schematic of the trolley assembly provided in an embodiment of this application. Further, the trolley assembly includes:

[0091] Pulley 8, which includes a crossbeam and a vertical beam;

[0092] Limit wheel 9, the limit wheel 9 is located on one side of the crossbeam;

[0093] The second magnet base 10 is located on the other side of the crossbeam of the trolley 8 and is arranged around the vertical beam.

[0094] The second magnet 11 is disposed on the second magnet base 10, with its positive pole facing away from the second magnet base 10, and the second magnet 11 is arranged around the vertical beam.

[0095] In the above embodiment, the trolley assembly consists of a trolley 8 body, including a crossbeam and a vertical beam structure. A limiting wheel 9 is installed on one side of the crossbeam to constrain the position of the trolley 8 and prevent lateral displacement. A second magnet base 10 is located on the other side of the crossbeam, surrounding the vertical beam. A second magnet 11 is fixed to the base with its positive pole facing downwards, creating a repulsive force with the first magnet 7 of the track assembly.

[0096] The limiting wheel 9 in this design effectively prevents the trolley from deviating and protects the track and trolley 8 from damage. The positive pole of the second magnet 11 faces downwards and interacts with the track magnet, achieving non-contact levitation and eliminating the risk of guide wheel jamming. This structure simplifies the movement mechanism and enhances the system's stability in vibration environments.

[0097] See Figure 4 and Figure 5 The diagram shows a structural schematic of a tow cable assembly provided in an embodiment of this application. Further, the tow cable assembly includes:

[0098] Connecting plate 12, connecting plate 12 is connected to the vertical beam;

[0099] Buffer blocks are located at the ends of the connecting plate 12, and there are multiple buffer blocks.

[0100] The second fixing bolt 13 is located at the connection between the connecting plate 12 and the vertical beam.

[0101] Traction ring 14, the traction ring 14 is provided at both ends of the connecting plate 12;

[0102] The cable layer 15 is connected to the connecting plate 12 and has a semi-circular structure.

[0103] Fixing clip 16, the fixing clip 16 is provided on the cable dragging layer 15, and there are multiple fixing clips 16, which are used to clamp the cable dragging layer 15.

[0104] Counterweight 17 is connected to the towing cable layer 15.

[0105] In the above embodiment, the towing cable assembly is connected to the vertical beam of the trolley 8 via a connecting plate 12, and the connecting plate 12 is fixed by a second fixing bolt 13. Multiple buffer blocks and traction rings 14 are provided at both ends of the connecting plate 12. The buffer blocks absorb the impact force generated by the movement of the trolley. The traction rings 14 are used to connect the traction rope, which sequentially pulls multiple trolley assemblies in series and finally connects to the traveling trolley. The towing cable layer 15 has a semi-circular structure and is connected to the connecting plate 12. Multiple fixing clips 16 are fixed to the towing cable layer 15 for clamping and fixing the power supply cable. A counterweight 17 is attached below the towing cable layer 15 to adjust the magnetic levitation height and ensure smooth operation.

[0106] The buffer block effectively reduces the impact of collisions between the trolleys on the connecting structure and cables. The traction ring 14 and traction rope provide a reliable trolley tandem traction mechanism, ensuring that all trolleys move synchronously with the trolley. The semi-circular cable layer 15 and fixing clamp 16 firmly protect the cable from wear and bending during movement. The counterweight 17 finely adjusts the suspension height, preventing excessive pulling or slack in the cable, thus improving overall power supply reliability and cable life, and reducing maintenance frequency.

[0107] Furthermore, the cleaning system includes:

[0108] Dustproof components are located at the connection between the track components and the towing cable components;

[0109] A first dust scraper assembly is connected to a second magnet 11;

[0110] The second dust scraper assembly is connected to the guide rail 4.

[0111] In the above embodiment, the cleaning system consists of a dustproof component, a first dust scraper component, and a second dust scraper component, all of which are installed on the transport system. The dustproof component covers the connection between the track and the tow cable, isolating dust; the first dust scraper component is attached to the trolley and cleans the surface of the magnet; the second dust scraper component is located at the track joint and removes dust from the guide rail.

[0112] This system effectively prevents dust accumulation on magnets or tracks, avoiding levitation failures or jamming. The automatic cleaning mechanism reduces manual intervention, ensuring efficient system operation in dusty environments. This extends magnet lifespan and reduces the failure rate caused by dust.

[0113] Furthermore, the dustproof components include:

[0114] Dustproof guide wheel, the dustproof guide wheel is set in the guide rail groove 5;

[0115] Dustproof device, the end of the dustproof device is connected to the dustproof guide wheel;

[0116] Dustproof buckle, the dustproof buckle is set on the dustproof device and is connected to the connecting plate 12.

[0117] In the above embodiment, the dustproof component includes a dustproof guide wheel that slides within the guide rail groove 5; one end of the dustproof device is connected to the dustproof guide wheel, and the other end is fixed to the connecting plate 12 via a dustproof buckle. The dustproof device is made of a flexible shrinkable material to cover the gap between the track and the tow cable.

[0118] This structure allows the dustproof guide rollers to move smoothly within the chute, ensuring the dustproof device seals the track and isolates external dust. Dustproof clips provide a reliable connection to prevent detachment, and the flexible material adapts to the trolley's movement, improving dustproof performance and reducing cleaning frequency and maintenance workload.

[0119] Furthermore, the first dust scraper assembly includes:

[0120] Mounting plate 18, which is connected to the second magnet 11;

[0121] The first sensor 19 is located inside the mounting plate 18;

[0122] The first spring 20 is partially located inside the mounting plate 18 and partially located outside the mounting plate 18.

[0123] The first dust scraper 21 is connected to the first spring 20.

[0124] In the above embodiment, the first dust-scraping assembly includes a mounting plate 18 connected to a second magnet 11; it has a first sensor 19 and a first spring 20 internally; the first spring 20 is externally connected to a first dust-scraping plate 21. The sensor monitors the pressure, and the spring pushes the dust-scraping plate to contact the magnet, providing real-time feedback on the wear status.

[0125] The first sensor 19 of this component monitors the wear of the dust scraper blade through pressure values ​​and provides timely warnings for replacement. The first spring 20 ensures that the first dust scraper blade 21 always adheres to the magnet surface, effectively removing dust, avoiding suspension instability caused by magnet contamination, and reducing sudden malfunctions.

[0126] See Figure 6 and Figure 7 The diagram shows a structural schematic of the second dust-scraping assembly provided in an embodiment of this application. Further, the second dust-scraping assembly includes:

[0127] Mounting block 22 is connected to guide rail 4;

[0128] The second spring 23 is located inside the mounting block 22;

[0129] Connecting rod 24, connecting rod 24 is connected to second spring 23;

[0130] The second dust scraper 25 is connected to the connecting rod 24.

[0131] In the above embodiment, the second dust scraping assembly includes a mounting block 22, which is fixed at the joint of the guide rail 4; it contains a second spring 23 and a connecting rod 24; the end of the connecting rod 24 is connected to the second dust scraper 25. The spring drives the dust scraper to rise and fall, cleaning the surface of the guide rail as needed.

[0132] The second scraper blade 25 of this design can lift the gap between the cleaning guide rails to prevent dust from clogging the trolley and causing it to jam. The spring mechanism ensures gentle contact, avoids damage to the rails, improves cleaning efficiency, and reduces the burden of manual inspection.

[0133] Furthermore, the early warning system includes:

[0134] The first monitoring device is installed on the trolley 8 and is used to monitor the distance between the trolley 8 and the trolley track 2.

[0135] The second monitoring device is located inside the first dust removal assembly and is used to monitor the pressure value of the first dust removal assembly.

[0136] In the above embodiment, the early warning system includes a first monitoring device installed on the trolley 8 to monitor the gap between the trolley 8 and the trolley track 2; and a second monitoring device located inside the first dust scraper assembly to monitor the pressure of the dust scraper blades. The system provides feedback on abnormalities, such as insufficient gap or insufficient pressure, through warning signals.

[0137] This system can monitor key parameters in real time, such as the trolley clearance and the condition of the dust scraper, obtained through the first sensor 19, to prevent jamming or wear failures. The early warning mechanism reduces the need for manual inspections, triggers maintenance in advance, avoids major accidents such as cable breakage, and ensures continuous operation of the crane.

[0138] The warning system also includes a traction rope warning device. This device includes a pressure switch integrated into one end of the traction rope, preferably near the drive end of the trolley or the fixed end where the force is greatest. The pressure switch monitors the tension on the traction rope in real time.

[0139] This device actively monitors the load status of the traction rope. When the tension on the traction rope reaches a preset warning threshold, the device will issue a warning signal to remind the operator to check. When the tension further increases and exceeds a higher overload threshold, the device will immediately issue an overload signal and simultaneously trigger the disconnection of the control power supply to the trolley. This graded response mechanism effectively prevents catastrophic accidents caused by traction rope overload breakage, such as subsequent pulley block loss of control, forced pulling or even tearing of power cables, greatly improving the safety and reliability of the system and ensuring the continuity of production.

[0140] This application provides a schematic diagram of the structure of a towing cable pulley device, including: a transport system, which includes a track assembly, a pulley assembly, and a towing cable assembly; the pulley assembly is connected to the track assembly, and the towing cable assembly is connected to the pulley assembly; a cleaning system, which is installed on the transport system; and an early warning system, which is installed on the transport system. This application provides a cable-dragging trolley device that effectively overcomes the technical defects of traditional structures where power cables are damaged by pulling due to localized operational obstruction or connection failure. It adopts a magnetic levitation operation mode, where the trolley levitates above the guide rails through the repulsive force between magnets, eliminating the need for traditional guide wheel structures and solving the risk of jamming caused by dust accumulation and wear. A dynamic counterweight system is configured in the cable-dragging assembly to effectively maintain operational stability and reduce the possibility of the cable being subjected to overload tension. An integrated real-time monitoring and early warning system continuously monitors key operating parameters, including trolley clearance, pressure of the first dust scraper assembly (i.e., the value monitored by the first sensor 19), and tension of the traction rope. Once a critical risk value is detected, protective intervention can be implemented before cable damage. The accompanying cleaning system continuously removes contaminants from the guide rails and magnet surfaces through the first dust scraper 21 and the second dust scraper 25, reducing factors that induce obstruction at the source and ensuring the long-term reliable operation of the magnetic levitation system. This significantly improves the overall reliability and safety of this application and avoids expensive replacement costs and production interruption losses caused by accidental cable damage.
