Description

Technical Field

[0001] This utility model belongs to the field of raw material conveying and relates to a steel cable conveyor. Background Technology

[0002] In the field of raw material transportation, traditional belt conveyors, with their mature technology and relatively simple structure, have long held a wide range of applications, playing a vital role in material handling across numerous industries. However, with the continuous and rapid expansion of industrial production, the requirements for raw material transportation are becoming increasingly stringent, and the need for long-distance, high-volume raw material transportation is becoming more urgent. Against this backdrop, the limitations of traditional belt conveyors are gradually becoming apparent, becoming a bottleneck restricting further improvements in industrial production efficiency.

[0003] Traditional belt conveyors are relatively bulky, a characteristic that is particularly pronounced in long-distance conveying scenarios. Long-distance conveying means laying longer conveyor belts, and to ensure the stability and strength of the conveyor belt during operation, numerous intermediate support structures must be installed. These support structures are not only numerous but also widely distributed, requiring significant investment of manpower, materials, and financial resources from equipment procurement to installation and commissioning. The increased equipment cost mainly lies in the material and manufacturing costs of the support structures themselves, while installation costs encompass labor, transportation, and site preparation. The high cost forces companies to carefully weigh the input and output when considering using traditional belt conveyors for long-distance conveying, thus limiting their large-scale application to some extent.

[0004] During operation, conveyor belts often encounter a series of problems due to the constraints of the supporting structure. Belt misalignment is a common issue. When a conveyor belt misaligns, it causes material spillage, resulting in waste and increased cleaning difficulty and time. Furthermore, misalignment causes friction between the conveyor belt edges and the supporting structure, accelerating wear and shortening its lifespan. Severely worn conveyor belts require frequent replacement, increasing equipment maintenance costs and causing production interruptions and downtime, ultimately leading to economic losses for the company.

[0005] Furthermore, traditional belt conveyors are poorly adaptable to complex terrain or space-constrained environments. In complex terrains such as mountains and hills, traditional belt conveyors struggle to adjust flexibly to the terrain's contours, requiring extensive earthwork to level the site, increasing construction costs and difficulty. In space-constrained environments, such as underground mines and narrow workshops, the bulky size and fixed structure of traditional belt conveyors prevent them from meeting actual production needs, limiting their application in these challenging environments.

[0006] While some improved conveying equipment exists on the market to address these issues, these devices often only improve performance in certain aspects to a limited extent and cannot simultaneously meet requirements such as lightweight structure, stable long-distance conveying, and adaptability to complex terrain. Therefore, developing a new type of cable conveyor and its transport trolley to improve the current situation has become a critical issue urgently needing to be addressed in the field of industrial raw material conveying. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a cable conveyor that achieves long-distance, stable and efficient material transportation with a lighter structure, while improving the equipment's adaptability to complex terrain and space, and reducing equipment and maintenance costs.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A cable conveyor includes a head transfer device, two reversing mechanisms, and a tail transfer device arranged in sequence. A conveyor belt is arranged around the head transfer device and the tail transfer device, and an annular steel cable is provided between adjacent reversing mechanisms.

[0010] It also includes a transport trolley that travels on the annular steel cable. The transport trolley includes a frame, a traveling wheel disposed on the side of the frame near the annular steel cable, and a strike bar rotatably connected to the side of the frame away from the traveling wheel. The transport trolley travels on the annular steel cable via the traveling wheel and supports the conveyor belt.

[0011] The reversing mechanism includes a rotary wheel and a guide plate. The annular steel cable is connected to the rotary wheel. The guide plate has a protrusion on one side relative to the running direction of the transport vehicle. When the transport vehicle runs to the guide plate, the protrusion contacts the impact rod. Under the guidance of the protrusion, the impact rod rotates and opens, making it easier for the transport vehicle to turn around the outer circumference of the rotary wheel.

[0012] Optionally, the guide plate is a closed shape composed of two parallel semi-circular steel plates, and the two ends of the two semi-circular steel plates are connected by the protrusion; the protrusion is a smooth cone shape and protrudes in the direction in which the transport vehicle is coming.

[0013] Optionally, the impact bar is connected to the vehicle frame via a pivot shaft, and a torsion spring is provided on the outside of the pivot shaft. Under the action of the torsion spring, the impact bar has an automatic return-to-center function.

[0014] Optionally, the rotating shaft is equipped with a bearing, a fixing pin, and a self-locking cable clamp; the fixing pin prevents the impact bar from falling off; when the impact bar rotates to open, it drives the self-locking cable clamp to tighten the annular steel cable, and closes as the impact bar rotates, and is reset by the action of the torsion spring.

[0015] Optionally, a safety pin is also provided on the side of the frame near the running wheel, and guide limit steel cables are provided on both sides of the slewing wheel. The safety pin and the guide limit steel cables cooperate to control the running direction of the trolley when it turns, prevent the trolley from deviating or derailing during the turning process, and improve the operation safety.

[0016] Optionally, two impact bars are provided symmetrically along the width direction of the conveyor belt.

[0017] Optionally, the reversing mechanism further includes a support frame, and the rotary wheel and guide plate are mounted on the support frame.

[0018] Optionally, the head transfer device and the tail transfer device each include a roller and a drive device for driving the roller to rotate, so as to realize the operation of the conveyor belt.

[0019] Optionally, it also includes idlers, support legs, and intermediate frames; the idlers are used to support the conveyor belt and reduce friction between the conveyor belt and other components; the support legs and intermediate frames provide structural support for the head transfer device and the tail transfer device.

[0020] Optionally, a tensioning device is also included, which is respectively installed on the lower part of the conveyor belt and the annular steel cable between the reversing mechanism and the transfer device, so as to keep the conveyor belt and the annular steel cable in a taut state and provide stable support for the operation of the transport trolley.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention achieves long-distance, stable, and efficient raw material transportation with a lightweight structure, while improving the equipment's adaptability to complex terrain and space, reducing equipment and maintenance costs. It is particularly suitable for mines, ports, large factories, and other places that require long-distance, high-volume raw material transportation.

[0023] The trolley of this invention travels on a ring-shaped steel cable via wheels and supports the conveyor belt. Compared with the large number of intermediate support structures in traditional belt conveyors, this greatly reduces the weight and volume of the equipment, and lowers the equipment cost and installation cost.

[0024] The ring-shaped steel cable can be tensioned by hydraulic pressure and counterweight to ensure stability during the conveying process; the arc-shaped support wheel structure and guide limit steel cable of the trolley ensure the stability of the trolley during long-distance operation, reduce belt deviation and wear, and improve conveying efficiency and equipment service life.

[0025] The special design of the reversing mechanism enables the transport trolley to turn smoothly in complex terrain and space-constrained locations, improving the equipment's adaptability to different environments. At the same time, the lightweight structure facilitates installation and adjustment, meeting the needs of a wider range of scenarios.

[0026] The conveyor's overall structure is rationally designed, reducing friction and wear between components and lowering the probability of malfunctions. Furthermore, the installation and disassembly of each component are relatively convenient, facilitating daily maintenance and repair, thereby reducing maintenance costs and downtime, and improving production efficiency.

[0040] Example 1

[0041] Please see Figures 1-6 A cable conveyor includes a head transfer device 4, two reversing mechanisms 3, and a tail transfer device 9 arranged in sequence. A conveyor belt 2 is arranged around the head transfer device 4 and the tail transfer device 9. A ring-shaped steel cable 18 is provided between adjacent reversing mechanisms 3.

[0042] The cable conveyor also includes a transport trolley 1 that travels on the annular cable 18. The transport trolley 1 includes a frame 10, a traveling wheel 12 disposed on the side of the frame 10 near the annular cable 18, and a bumper 11 rotatably connected to the side of the frame 10 away from the traveling wheel 12. The transport trolley 1 rolls on the annular cable 18 via the traveling wheel 12 and supports the conveyor belt 2.

[0043] The reversing mechanism 3 includes a rotary wheel 6 and a guide plate 7. An annular steel cable 18 is connected to the rotary wheel 6. The guide plate 7 has a protrusion on one side relative to the running direction of the transport trolley 1. When the transport trolley 1 runs to the guide plate 7, the protrusion contacts the impact rod 11. Guided by the protrusion, the impact rod 11 rotates and opens, facilitating the transport trolley 1 to turn around the outer circumference of the rotary wheel 6. The reversing mechanism 3 also includes a support frame 8, on which the rotary wheel 6 and the guide plate 7 are mounted.

[0044] The head transfer device 4 and the tail transfer device 9 each include a roller and a drive device for driving the roller to rotate. The drive device provides power to the entire cable conveyor, driving the conveyor belt 2 and the transport trolley 1 to move and realize the transport of raw materials.

[0045] The cable conveyor also includes idlers, support legs, and intermediate frames; the idlers are used to support the conveyor belt 2 and reduce friction between the conveyor belt 2 and other components; the support legs and intermediate frames provide structural support for the head transfer device 4 and the tail transfer device 9.

[0046] The cable conveyor also includes a tensioning device 5, which is installed on the lower conveyor belt 2 and the annular steel cable 18 between the reversing mechanism 3 and the transfer device, so that the conveyor belt 2 and the annular steel cable 18 are kept taut, providing stable support for the operation of the transport trolley 1.

[0047] The tensioning device 5 includes hydraulic tensioning and counterweight tensioning. In some embodiments of this invention, the annular steel cable 18 is wound around the two rotating wheels 6 and is hydraulically tensioned to ensure that the annular steel cable 18 is always in a suitable tension state, providing stable support for the operation of the transport trolley 1. The conveyor belt 2 is tensioned by counterweight. The counterweight tensioning and hydraulic tensioning work together to ensure the tension of the conveyor belt 2 and the annular steel cable 18, ensuring the stable operation of the equipment.

[0048] Working principle: The head drive device drives the head roller to rotate, which in turn drives the conveyor belt 2. The conveyor belt 2, through friction, drives the trolley 1 to travel on the annular steel cable 18 via the traveling wheels 12. The trolley 1 also provides support for the conveyor belt 2. When the trolley 1 reaches the reversing point, the impact bar 11 collides with the front protruding cone section of the guide plate 7 and remains open under the action of the guide plate 7, allowing the trolley to avoid the conveyor belt 2 and flip downwards. When it flips to the lower running position, it moves away from the guide plate 7 section, and the impact bar 11 returns to its original position under the action of the torsion spring 14, thus supporting the return conveyor belt 2. The safety pin 17 at the bottom of the frame 10, during rotation, is aligned with the guide limit steel cables 19 on both sides of the slewing wheel 6 to control the trolley's rotation trajectory.

[0049] Example 2

[0050] Based on Embodiment 1, this embodiment defines the guide plate 7 as a closed shape composed of two parallel semi-arc steel plates, with the two ends of the two semi-arc steel plates connected by a protrusion; the protrusion is a smooth cone shape and protrudes in the direction of the transport vehicle 1.

[0051] The impact bar 11 is connected to the frame 10 via a rotating shaft 15. A torsion spring 14 is provided on the outside of the rotating shaft 15, which enables the impact bar 11 to automatically return to its original position. The rotating shaft 15 is equipped with a bearing, a fixing pin, and a self-locking cable clamp. The fixing pin prevents the impact bar 11 from falling off. When the impact bar 11 rotates open, it drives the self-locking cable clamp to tighten the annular steel cable 18, and then closes as the impact bar 11 rotates, with the torsion spring 14 acting as the clamp to reset. Two impact bars 11 are symmetrically arranged along the width of the conveyor belt 2. When the impact bar 11 contacts the protrusion of the guide plate 7, guided by the smooth conical surface of the guide plate 7, the two impact bars 11 rotate outward and remain open, enabling the trolley 1 to turn smoothly until the trolley 1 leaves the area of ​​the guide plate 7. When the trolley 1 moves to the point where the impact bar 11 leaves the guide plate 7, the two impact bars 11 return to their original position and close.

[0052] Example 3

[0053] Based on Embodiment 1 or 2, this embodiment further specifies that a safety pin 17 is provided on the side of the frame 10 near the running wheel 12, and guide limit steel cables 19 are provided on both sides of the slewing wheel 6. The safety pin 17 and the guide limit steel cables 19 cooperate to control the running direction of the trolley 1 when it turns, prevent the trolley from deviating or derailing during the turning process, and improve the operational safety.

[0054] Example 4

[0055] Based on any of the above embodiments, this embodiment further specifies that the trolley 1 is symmetrically provided with arc-shaped support wheels 13 on both sides, which can act on the annular steel cable 18 and the running wheels 12, and are used for running balance during the operation of the trolley to ensure the smooth operation of the trolley and reduce the wear of the conveyor belt 2.

[0056] There is a gap between the arc-shaped support wheels 13 and the impact rods 11 at the bottom of both sides of the trolley 1. During operation, support facilities such as wire ropes, rollers, and rails can be set to maintain the balance of the trolley.

[0057] This utility model achieves efficient and stable reversing of the transport trolley 1 through the mechanical linkage between the protrusion of the guide plate 7 and the impact rod 11, and the synergistic effect of the arc-shaped support wheel 13 and the ring steel cable 18. At the same time, the lightweight design reduces the complexity of the system, making it suitable for long-distance and high-volume transport scenarios, and significantly improving the efficiency and reliability of raw material transportation.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
