Description

Technical Field

[0001] This invention relates to the technical field of mobile power supply devices for the upper cable of a bucket wheel stacker-reclaimer, and more specifically, to a mobile power supply towing device for a bucket wheel stacker-reclaimer. Background Technology

[0002] Bucket wheel stacker-reclaimers are key loading and unloading equipment in bulk material storage yards such as ports, docks, and power plants. Their trolleys need to travel back and forth on rails to carry out stacking and reclaiming operations, so mobile power supply devices are an important component.

[0003] Currently, cable reels are commonly used for mobile power supply in bucket wheel stacker-reclaimers. However, cable reels have several drawbacks in practical applications: due to their low installation height and the light weight of the vertical cable section, the torque adjustment requirements for the cable reel control device during cable winding and unwinding are extremely high, making control difficult; simultaneously, the vibrations generated during machine operation cause prolonged wear between the slip ring and the conductive brush, creating phase gaps and preventing the equipment from starting normally, seriously affecting the safe operation of the bucket wheel stacker-reclaimer. Furthermore, cable reels must use expensive three-in-one special cables and require complex electrical control systems, resulting in high maintenance costs.

[0004] To address the aforementioned issues, existing technologies have introduced mobile power supply solutions using towing devices. One example is a bucket wheel stacker-reclaimer towing conveyor system, which includes a guide rail, a slidable trolley mounted on the guide rail, a conveyor belt laid on the trolley, and cable clamps for securing cables. It is connected to a trolley via a traction head, enabling it to be towed by the main unit. This solution, to some extent, resolves the problems of slip ring wear and complex control associated with cable reels.

[0005] However, in practical applications, especially in bulk material handling environments such as docks and mines, the above-mentioned towing devices still have the following technical problems: First, there is the issue of dust pollution. During operation, material falling from the top will enter the guide rail area, while slag from the bottom will seep into the guide rail, causing the trolley to jam, accelerating wear, and severely affecting the service life and operational reliability of the device. Existing towing devices lack targeted protective structures and are difficult to adapt to extreme dust environments.

[0006] Second, there is the problem of limited functionality. Existing towing devices typically only have power cables laid, which cannot meet the water supply requirements of the dust removal equipment of bucket wheel stacker-reclaimers. A separate water supply pipeline needs to be laid, which increases the complexity of ground facilities and maintenance costs. Summary of the Invention

[0007] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0008] The present invention aims to provide, for example, a mobile power supply towing device for a bucket wheel stacker-reclaimer, which can improve the problems of poor reliability and limited functionality of existing bucket wheel stacker-reclaimer towing devices in bulk material operation environments.

[0009] The embodiments of the present invention can be implemented as follows: An embodiment of the present invention provides a mobile power supply towing device for a bucket wheel stacker-reclaimer, comprising a guide rail, a trolley, a flexible support body, a cable fixing device, an upper baffle plate, a lower baffle plate, a power cable, and a mobile water cable. The guide rail is laid along the traveling direction of the bucket wheel stacker-reclaimer; the trolley is slidably mounted on the guide rail; the flexible support body is laid on the trolley and can move synchronously with the trolley; the cable fixing device is mounted on the flexible support body and is used to fix the cable; the upper baffle plate is located above the guide rail and is used to prevent material from falling into the guide rail area; the lower baffle plate is located on the inner side of the flexible support body and is used to clean the inner side of the flexible support body; the power cable is used to supply power to the bucket wheel stacker-reclaimer and is fixed to the flexible support body by the cable fixing device; the mobile water cable is used to supply water to the main dust removal equipment and is fixed to the flexible support body by the cable fixing device.

[0010] In addition, the mobile power supply towing device for the bucket wheel stacker-reclaimer provided in the embodiments of the present invention may also have the following additional technical features: Optionally, the upper baffle plate includes two plate-shaped structures arranged at an angle, and the two plate-shaped structures are respectively inclined towards both sides of the trolley to form a guide surface, which is used to guide the upper material to the outside of the guide rail.

[0011] Optionally, the upper baffle is arranged along the sliding direction of the trolley, and the length of the upper baffle at least covers the sliding stroke of the trolley.

[0012] Optionally, the lower baffle plate is provided with a gap between itself and the inner side of the flexible support body, and is able to scrape the ash inside the flexible support body and clean and discharge the ash from both sides of the flexible support body.

[0013] Optionally, the lower slag baffle is fixedly mounted on the trolley and located between the flexible support and the trolley. The lower slag baffle can move synchronously with the trolley to achieve follow-up cleaning.

[0014] Optionally, there are multiple lower slag baffles, which are spaced apart on the inner side of the trolley along the sliding direction of the trolley.

[0015] Optionally, the mobile power supply towing device for the bucket wheel stacker-reclaimer also includes a control cable. The control cable is used to transmit control signals and is fixed to the flexible carrier by the cable fixing device. The power cable and the control cable are laid separately and maintain a distance between them.

[0016] Optionally, the mobile power supply towing device for the bucket wheel stacker-reclaimer also includes an optical cable, which is used to transmit communication signals and is fixed to the flexible carrier by the cable fixing device.

[0017] Optionally, the control cable and the optical cable can be laid separately or combined into one.

[0018] Optionally, the flexible support body is a conveyor belt, which is wound around the outer periphery of the trolley.

[0019] The beneficial effects of the mobile power supply towing device for the bucket wheel stacker-reclaimer according to embodiments of the present invention include, for example: The mobile power supply and towing device for a bucket wheel stacker-reclaimer forms a comprehensive system solution integrating protection and installation. This is achieved by installing an upper baffle above the guide rail, a lower baffle inside the flexible support body, and simultaneously laying power cables and mobile water cables on the flexible support body. The guide rail is laid along the travel direction, and a trolley is slidably mounted on it. The flexible support body is laid on the trolley and moves synchronously with it. Cable fixing devices reliably secure the power cables and mobile water cables to the surface of the flexible support body. During operation, the upper baffle prevents material from falling outside the guide rail area, while the lower baffle, moving with the trolley, scrapes away accumulated dust inside the flexible support body and pushes ash and slag to both sides, fundamentally solving the dual problems of external material intrusion and internal dust abrasion in bulk material handling environments. Simultaneously, the power cable supplies power to the bucket wheel stacker-reclaimer, and the mobile water cable supplies water to the dust removal equipment, enabling the towing device to provide both reliable power supply and mobile water supply functionality. By integrating three-dimensional protection with internal and external coordination and power and water supply functions, the operational reliability in extreme dust environments is significantly improved, and the limitation of traditional towing devices that can only provide power is broken.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0024] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," "outer," or "vertical" appear, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use, and does 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, and therefore should not be construed as a limitation of this invention.

[0025] At the same time, it should be noted that the terms "first" and "second" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0026] In the description of this invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable 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, or a connection within two components, etc. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] While existing towing devices achieve the function of being dragged by the host machine, their structural design focuses only on how to drag the machine without considering reliable operation in harsh environments. In bulk material handling sites such as docks and mines, dust pollution is characterized by bidirectional intrusion: Above, contamination sources include materials spilled during material handling and dust raised during material stacking. These materials fall directly into the guide rail area, accumulating on the contact surface between the trolley rollers and the guide rails. This increases rolling resistance, accelerates wear, and ultimately leads to jamming. Below, contamination sources include coal slag and mineral powder accumulated on the ground. These are either kicked up by the tires or blown into the bottom of the guide rails by the moving trolley, infiltrating the trolley mechanism from below and causing similar wear and jamming. Existing technology completely ignores this two-way dust intrusion problem, lacking both upper and lower baffles. This results in a short lifespan and high failure rate in actual operation, making it difficult to meet the needs of continuous dock operations.

[0028] Furthermore, bucket wheel stacker-reclaimers generate a large amount of dust during operation, requiring environmental protection standards to equip them with water spraying and dust suppression devices. However, existing towing devices can only lay power cables and cannot simultaneously address the issue of water supply to the dust suppression equipment. Users are forced to lay separate ground water supply pipelines or adopt other complex methods to solve the water supply problem, increasing the complexity of ground facilities and maintenance costs, and also limiting the environmental performance of the equipment.

[0029] Faced with the aforementioned problems, the conventional thinking of those skilled in the art might be: to address the dust problem, add a local sealing cover to the pulley or cable; to address the water supply problem, lay a separate set of drag-on water pipes or use ground-fixed water pipes. However, this application breaks through this mindset of addressing problems only where they arise, and for the first time proposes a systematic solution that integrates protection and installation.

[0030] The following is combined with Figures 1 to 3 The mobile power supply towing device 10 for the bucket wheel stacker-reclaimer provided in this embodiment will be described in detail.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3An embodiment of the present invention provides a mobile power supply towing device 10 for a bucket wheel stacker-reclaimer, including a guide rail 100, a trolley 200, a flexible support body 300, a cable fixing device 400, an upper baffle plate 500, a lower slag baffle plate 510, a power cable, and a mobile water cable. The guide rail 100 is laid along the traveling direction of the bucket wheel stacker-reclaimer; the trolley 200 is slidably mounted on the guide rail 100; the flexible support body 300 is laid on the trolley 200 and can move synchronously with the trolley 200; the cable fixing device 400 is mounted on the flexible support body 300. The upper baffle plate 500 is located above the guide rail 100 and is used to prevent material from falling into the guide rail 100 area; the lower baffle plate 510 is located inside the flexible support body 300 and is used to clean the inside of the flexible support body 300; the power cable is used to supply power to the bucket wheel stacker-reclaimer and is fixed to the flexible support body 300 through the cable fixing device 400; the mobile water cable is used to supply water to the main dust removal equipment and is fixed to the flexible support body 300 through the cable fixing device 400.

[0032] An upper baffle plate 500 is positioned above the guide rail 100, forming a physical barrier to prevent material from falling directly into the guide rail 100 area. A lower baffle plate 510 is positioned inside the flexible support 300, capable of cleaning dust accumulated between the conveyor belt 310 and the trolley 200, preventing internal dust accumulation from causing wear on moving parts. A mobile water cable and a power cable are laid parallel to each other on the flexible support 300, fixed by a cable fixing device 400, and move synchronously with the towing device, providing a follow-up water source for the dust removal equipment.

[0033] The upper baffle plate 500 and the lower baffle plate 510 are not simply "two protective components superimposed," but rather form a three-dimensional protective space: the upper baffle plate 500 blocks the impact of falling material from above, protecting the upper part of the rollers of the trolley 200; the lower baffle plate 510 can clean up accumulated dust; together, they keep the operating areas of the guide rail 100 and the trolley 200 clean at all times, fundamentally eliminating dust-induced jamming and wear. This bidirectional protection design is not a simple addition of two independent protective functions, but rather achieves better protection through spatial complementarity, significantly improving the operational reliability of the device in extreme dust environments.

[0034] The introduction of the mobile water cable first solves the problem of water supply for the dust removal equipment, upgrading the towing device from a single power supply to a combined power and water supply function. More importantly, the water mist sprayed by the dust removal equipment connected to the water cable effectively suppresses dust during operation, reducing dust generation at the source. This reduction in total dust directly alleviates the protective pressure on the upper baffle plate 500 and the lower slag baffle plate 510, extending their service life. The long-term effectiveness of the baffles creates a clean operating environment for the water cable and its connected equipment, ensuring the reliability of the water supply system. The introduction of the water cable not only expands functionality but also forms a positive cycle with the baffles: water supply suppresses dust, reducing the protective burden, and good protection ensures reliable water supply. This synergistic effect far exceeds the mere addition of a pipe to the towing device. Even those skilled in the art, who may recognize the need for baffles and water supply separately, would find it difficult to conceive of combining the two in such a synergistic way to produce the aforementioned interconnected technical effects.

[0035] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the upper baffle plate 500 includes two plate-shaped structures arranged at an angle. The two plate-shaped structures are inclined to both sides of the trolley 200 to form a guide surface 501. The guide surface 501 is used to guide the upper material to the outside of the guide rail 100.

[0036] When the material falls onto the baffle plate, the figure-eight shaped guide surface 501 can guide the falling material to both sides of the guide rail 100, preventing the material from accumulating near the guide rail 100. This not only achieves passive blocking but also provides an active guiding function, effectively preventing the falling material from accumulating at the edge of the baffle plate and then re-entering the area of ​​the guide rail 100.

[0037] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the upper baffle plate 500 is arranged along the sliding direction of the trolley 200, and the length of the upper baffle plate 500 at least covers the sliding stroke of the trolley 200.

[0038] The upper baffle 500 ensures that material falling from any point during the entire travel process can be effectively intercepted by the material falling at any location. The bucket wheel stacker-reclaimer needs to travel back and forth along a track hundreds of meters long. If the baffle only covers a partial area, material falling from the uncovered areas will still fall directly into the guide rail 100, resulting in blind spots in protection. By setting up a full-length covering upper baffle 500, full-stroke protection of the trolley 200's travel trajectory is achieved, completely eliminating blind spots and further improving the reliability of the device in long-distance operating environments.

[0039] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the lower slag baffle 510 is provided with a gap between it and the inner side of the flexible support 300, and can scrape the ash and slag inside the flexible support 300 and clean and discharge the ash and slag from both sides of the flexible support 300.

[0040] The accumulated ash and slag on the inner side are cleaned by scraping and discharged from both sides of the flexible support 300. When the conveyor belt 310 runs around the trolley 200, a relatively enclosed space is formed between its inner side and the trolley 200, where dust easily accumulates and is difficult to remove by external blowing. The lower baffle plate 510 extends into this internal space, and through the scraping action generated by its relative movement, it peels off the dust adhering to the inner side of the conveyor belt 310 and pushes it to both sides, effectively controlling the internal pollution source.

[0041] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the lower slag baffle 510 is fixedly mounted on the trolley 200 and located between the flexible support 300 and the trolley 200. The lower slag baffle 510 can move synchronously with the trolley 200 to achieve follow-up cleaning.

[0042] The baffle plate maintains a constant relative position and gap with the inner side of the conveyor belt 310. No matter where the trolley 200 travels, the baffle plate continuously performs its cleaning function, achieving a dynamic cleaning effect that sweeps wherever it goes. If a fixed installation were used, the cleaning effect would be limited to a localized area and would not cover the entire travel distance. The dynamic design ensures the effectiveness of the cleaning function throughout the entire process, representing a breakthrough improvement over the fixed protection approach.

[0043] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, there are multiple lower slag baffles 510, and the multiple lower slag baffles 510 are spaced apart on the inner side of the trolley 200 along the sliding direction of the trolley 200.

[0044] During long-distance operation, a single baffle plate may experience reduced cleaning effectiveness due to wear or material buildup after prolonged use. Multiple baffle plates spaced apart create a redundant cleaning mechanism, ensuring that even if one baffle plate fails, the others can still maintain basic cleaning functionality. Furthermore, the segmented operation of multiple baffle plates more evenly pushes accumulated dust outwards, preventing secondary pollution caused by dust being dragged along the inner side of the conveyor belt 310 during single-point cleaning. This multi-stage cleaning layout reflects a deep consideration for the stability and uniformity of the cleaning effect.

[0045] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the mobile power supply towing device 10 of the bucket wheel stacker-reclaimer also includes a control cable. The control cable is used to transmit control signals and is fixed to the flexible carrier 300 by the cable fixing device 400. The power cable and the control cable are laid separately and maintain a distance between them.

[0046] Power cables carry high voltage and high current, generating strong electromagnetic fields during operation. If laid close to control cables, the strong electrical signals can easily interfere with the weak control signals, leading to mistransmission of control commands or equipment malfunctions. By laying them separately and maintaining physical distance, electromagnetic isolation is effectively achieved, ensuring the stability of the control system. Simultaneously, separate laying creates heat dissipation channels between the cables, facilitating the timely dissipation of heat generated during operation and delaying insulation aging. Furthermore, separate installation allows for individual repair and replacement, reducing maintenance costs.

[0047] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the mobile power supply towing device 10 of the bucket wheel stacker-reclaimer also includes an optical cable, which is used to transmit communication signals and is fixed to the flexible carrier 300 by the cable fixing device 400.

[0048] With the increasing intelligence of bucket wheel stacker-reclaimers, a large amount of data needs to be transmitted between devices. Traditional cables have limitations in terms of transmission bandwidth and anti-interference capabilities. The introduction of optical fiber enables the towing device to have high-speed communication capabilities, meeting the data transmission needs of modern smart ports. At the same time, optical fiber itself is not subject to electromagnetic interference, and when laid together with power cables and control cables, no complex shielding measures are required, further simplifying the cable layout.

[0049] In this embodiment, the control cable and optical cable are laid separately or combined into one.

[0050] When laid separately, control signals and communication signals are transmitted independently without interfering with each other, making it easy to inspect and replace them individually; the two-in-one design has a higher degree of integration and is suitable for scenarios with limited space or high requirements for simple wiring.

[0051] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the flexible support 300 is a conveyor belt 310, which is wound around the outer periphery of the trolley 200.

[0052] The conveyor belt 310, wound around the outer periphery of the trolley 200, forms a stable load-bearing platform, allowing cables and water cables to be laid flat, avoiding localized stress or bending, and providing a structural foundation for the installation of the upper and lower baffles and the realization of cleaning functions. This basic structure, together with the protection and laying functions of this application, constitutes a complete and reliable mobile power supply towing device.

[0053] Reference Figure 1 In this embodiment, the bucket wheel stacker-reclaimer mobile power supply towing device 10 also includes a roller assembly 600, which is disposed at the end of the flexible support body 300 and is used to guide the flexible support body 300 to turn.

[0054] Reference Figure 1 In this embodiment, the mobile power supply towing device 10 of the bucket wheel stacker-reclaimer also includes a cable guide block assembly 610, which is disposed at the inlet of the cable 410 and is used to guide the cable 410.

[0055] Reference Figure 1 In this embodiment, the bucket wheel stacker-reclaimer mobile power supply towing device 10 also includes a fixed roller assembly 620, which is disposed below the flexible support body 300 to support the flexible support body 300 and reduce running friction.

[0056] Reference Figure 1 In this embodiment, the mobile power supply towing device 10 of the bucket wheel stacker-reclaimer further includes a conveyor belt fixing and tensioning device 630. The conveyor belt fixing and tensioning device 630 is disposed at the end of the flexible support body 300 and is used to adjust the tension of the flexible support body 300. The conveyor belt fixing and tensioning device 630 includes a spring buffer mechanism for absorbing the impact load generated when the bucket wheel stacker-reclaimer starts and stops.

[0057] Reference Figure 1 In this embodiment, a conveyor belt traction head component 640 is also included. The conveyor belt traction head component 640 is disposed at one end of the flexible support body 300 and is used to connect with the trolley of the bucket wheel stacker-reclaimer.

[0058] According to the bucket wheel stacker-reclaimer mobile power supply towing device 10 provided in this embodiment, the working principle of the bucket wheel stacker-reclaimer mobile power supply towing device 10 is as follows: When the bucket wheel stacker-reclaimer trolley moves, the towing device connected to the traction head is synchronously dragged. The trolleys 200 on the guide rail 100 roll in the direction of the trolley's movement, and the flexible support body 300 (conveyor belt 310) laid above the trolleys 200, along with its fixed cables and water cables, moves synchronously. During operation, the upper baffle plate 500 above the guide rail 100 blocks material falling from the upper surface and guides it to both sides along the V-shaped guide surface 501, preventing material from falling into the guide rail 100 area. The lower baffle plate 510 inside the flexible support body 300 moves with the trolleys 200, scraping away dust accumulated inside the conveyor belt 310 and pushing ash and slag out from both sides, preventing internal dust accumulation from wearing down moving parts. The power cable supplies power to the equipment, and the mobile water cable supplies water to the dust removal device along with the trolley, achieving full-process follow-up for power supply, water supply, and movement. The entire device does not require an independent power source; it can complete mobile power supply and water supply operations simply by being towed by the trolley.

[0059] The mobile power supply towing device 10 for a bucket wheel stacker-reclaimer provided in this embodiment has at least the following advantages: Without the need for an independent power drive, it relies entirely on the synchronous drag of the bucket wheel stacker-reclaimer's trolley during movement, completely eliminating the need for the complex electrical control system and protective limit devices required for cable reels, significantly reducing power consumption at the dock. The follow-drive method simplifies the device structure, reduces moving joints, and results in an extremely low equipment failure rate, achieving true energy saving, environmental protection, and maintenance-free operation.

[0060] By setting up an upper baffle plate 500 and a lower baffle plate 510, a three-dimensional protection system combining internal and external components is formed. The upper baffle plate 500 prevents material from falling from the upper part and intruding into the guide rail 100 area, while the lower baffle plate 510 performs follow-up cleaning of dust accumulated on the inner side of the conveyor belt 310. This effectively solves the problem of trolley 200 jamming and wear caused by dust pollution in bulk material operation environments, enabling the device to operate safely and reliably under any extreme working conditions such as wind load, vibration, and frequent reversing.

[0061] It can simultaneously lay power cables, control cables, communication optical fibers, and mobile water cables, realizing integrated follow-up conveying of power supply, control, communication, and water supply, meeting the water needs of the dust removal equipment of bucket wheel stacker-reclaimers. The cable type is not limited to expensive three-in-one special cables; power cables and control cables can be installed separately, significantly reducing cable procurement costs, and any damaged line can be replaced individually, avoiding the scrapping of the entire system.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
