Description

Technical Field

[0001] The utility model belongs to the technical field of raw material conveying, and relates to a cable tubular conveyor. Background Art

[0002] In a modern industrial production system, raw material conveying is a key link connecting various production links, and its efficiency and reliability directly affect the smoothness and economic benefits of the overall production process. Among many raw material conveying equipment, tubular belt conveyors occupy an important position in raw material conveying scenarios with long distances, large conveying capacities and many path obstacles due to their unique advantages.

[0003] The reason why tubular belt conveyors are widely used in complex scenarios stems from their many significant advantages. From the perspective of space utilization, it adopts a tubular structure, which folds the conveyor belt into a closed tubular shape, greatly reducing the occupation of lateral space. Compared with the traditional open conveyor belt, under the same conveying capacity, the space required by the tubular belt conveyor is greatly reduced, which enables it to flexibly shuttle through narrow passages, dense buildings or complex underground spaces, and effectively solves the problem that traditional conveying equipment is difficult to arrange due to large space requirements. In terms of conveying capacity, the tubular belt conveyor has a strong conveying capacity, can stably convey a large amount of raw materials, and meets the demand for continuous supply of raw materials in large-scale industrial production. At the same time, its closed tubular structure effectively prevents raw materials from spilling and flying during conveying, reduces pollution to the surrounding environment, has good environmental friendliness, and conforms to the current concept of green development.

[0004] However, the tubular belt conveyor is not perfect, and it also exposes some non-negligible limitations in practical application. The first problem is power consumption. Since the conveyor belt of the tubular belt conveyor needs to maintain its tubular shape and overcome various resistances to move during operation, the driving system needs to consume more energy to maintain normal operation. Compared with some traditional conveying equipment, the power consumption of the tubular belt conveyor is obviously larger, which not only increases the operating cost of enterprises, but also does not conform to the development trend of energy conservation and emission reduction.

[0005] The necessary transfer link is also a major shortcoming of the tubular belt conveyor. In the process of long-distance conveying, limited by factors such as the strength of the conveyor belt and equipment layout, multiple transfers are often required. Each transfer requires additional equipment, such as transfer stations, hoppers, etc., which not only increases the investment cost of equipment, but also easily causes problems such as raw material blockage and spilling during the transfer process, affecting the stability and reliability of conveying.

[0006] Furthermore, tubular belt conveyors require numerous support and frame structures to support and secure the conveyor belt. These supports and frame structures are not only numerous but also require precise design and installation based on the terrain and layout of the conveying path, making construction quite challenging. They also occupy a considerable amount of space, further limiting the application of conveyors in space-constrained locations. Moreover, sufficient space is essential for the normal operation of tubular belt conveyors. Besides the space required for supports and frames, the installation, maintenance, and repair of the equipment also require a certain amount of operating space, which is often difficult to meet in some confined industrial environments.

[0007] Given these limitations of tubular belt conveyors, the development of new technical solutions is urgently needed. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a cable-tube conveyor that combines the advantages of cableways, while improving the adaptability of the equipment to complex terrain and space, and reducing equipment and maintenance costs.

[0009] To achieve the above objectives, this utility model provides the following technical solution: A cable-stayed tubular conveyor includes a cableway support system and a reversing mechanism disposed at the end of the cableway support system. A head-and-tail transfer device is provided on the side of the reversing mechanism away from the cableway support system. The cableway support system includes a load-bearing cable and a track cable, which are arranged in parallel and connected to the upper and lower ends of the reversing mechanism. At least two track cables are provided, respectively disposed on both sides of the load-bearing cable. Several tubular trolleys run along the load-bearing cable and the track cable. A conveyor belt is disposed within the tubular trolleys and extends along the arrangement direction of the tubular trolleys, bypassing the head-and-tail transfer device. The conveyor belt is tubular during the loading process of the tubular trolleys and unfolds near the head-and-tail transfer device. The tubular trolleys run along the load-bearing cable and the track cable, and reverse direction at the reversing mechanism.

[0010] Optionally, the tube forming trolley includes a lower support groove and an upper rotating rod. The bottom of the support groove is provided with a support wheel, and the sides of the support groove are provided with traveling wheels. The support wheel travels on the bearing cable, and the traveling wheels travel on the track cable.

[0011] Optionally, at least two symmetrical rotary rods are provided, and each is rotatably mounted on the bracket via a rotary shaft.

[0012] Optionally, the rotary shaft is provided with a cam spring mechanism to return the rotary rod to its original position.

[0013] Optionally, the top of the rotary rod is provided with a guide wheel and the inner side is provided with a tube forming roller. The tube forming roller contacts the conveyor belt, so that the conveyor belt is kept in a tubular shape, and the friction between the tube forming roller and the conveyor belt drives the tube forming trolley to run along the running direction of the conveyor belt.

[0014] Optionally, the head and tail transfer device includes head and tail rollers, a drive device, a tensioning device, and a support bracket; the conveyor belt is wound around the head and tail rollers, the drive device is connected to the head and tail rollers to drive the head and tail rollers to rotate, thereby driving the conveyor belt to run, and the tensioning device is disposed on the conveyor belt; the support bracket is disposed at the bottom of the unfolded conveyor belt.

[0015] Optionally, a tube-forming support is provided between the support bracket and the reversing mechanism. The tube-forming support has tube-forming holes, and the conveyor belt is rolled up into a tube shape on both sides after passing through the tube-forming holes.

[0016] Optionally, the reversing mechanism is mounted on the support frame. The reversing mechanism includes a reversing wheel and a semi-annular guide plate disposed outside the reversing wheel. The annular opening of the guide plate faces the tube-forming trolley, and the end of the guide plate facing the tube-forming trolley has a smooth conical protrusion. When the tube-forming trolley runs to the guide plate, the rotary rod contacts the protrusion. Under the action of the protrusion, the rotary rod rotates and opens, and the tube-forming trolley runs to the radially opposite side of the reversing wheel under the limiting action of the guide plate.

[0017] The beneficial effects of this utility model are as follows: This invention is particularly suitable for places such as mines, ports, and large factories that require long-distance, high-volume transportation of raw materials. Compared with existing tubular conveyors, it has a lighter structure and lower energy consumption.

[0018] (1) The steel cable tubular conveyor of this utility model uses load-bearing cable and track cable as "aerial track" to replace the traditional rigid support. It can cross obstacles such as valleys, rivers and roads, reduce earthwork and protect the ecological environment. Compared with ordinary tubular conveyors, it can realize large-span conveying by using cableway structure and can be applied to material conveying in complex terrain and obstacles.

[0019] (2) It can realize long-distance straight single-transport, replacing the traditional mode of multiple short-distance conveyors plus transfer stations, reducing the construction cost of transfer stations, material transfer loss and dust pollution, and improving system reliability.

[0020] (3) Compared with the traditional tubular conveyor frame structure, the steel cable structure is lighter and more convenient, reducing the cost of steel structure raw materials, transportation costs and foundation construction costs, resulting in a lower overall cost.

[0021] (4) Since the rolling friction resistance of the tube trolley on the steel cable is small, the use of steel cable transportation reduces the friction and wear between components, significantly reduces the overall energy consumption, has fewer moving parts and is standardized, is convenient for maintenance and inspection, and has a low life cycle cost.

[0022] The lightweight nature of this utility model's cable-stayed structure provides the physical basis for achieving long-span transportation and reducing foundation costs. Its lightweight structure allows for more economical long-distance erection. The simple structure and low-friction operation result in lower energy consumption, while fewer mechanical parts make maintenance easier, thus reducing overall life-cycle operating costs.

At least two track cables 7 are provided, each located on one side of the load-bearing cable. Several tubular trolleys 6 run along the load-bearing cable and the track cable 7. A conveyor belt 5 is located inside the tubular trolleys 6 and extends along the direction of the tubular trolleys 6, bypassing the head-and-tail transfer device. The conveyor belt 5 is tubular during the loading process of the tubular trolleys 6 and unfolds near the head-and-tail transfer device. The tubular trolleys 6 move along the load-bearing cable and the track cable 7, and then reverse direction at the reversing mechanism 4.

[0030] Furthermore, the tube forming trolley 6 includes a lower support groove 15 and an upper rotating rod 11. The bottom of the support groove 15 is provided with a support wheel 16, and the sides of the support groove 15 are provided with traveling wheels 12.

A tube-forming roller 14 is provided on the inner side of the rotary rod 11, which contacts the conveyor belt 5, keeping the conveyor belt 5 in a tubular shape and reducing frictional resistance.

[0033] Example 2 Based on Embodiment 1 above, this embodiment further specifies that a tube-forming support 31 is provided between the support bracket 32 ​​and the reversing mechanism 4. The tube-forming support 31 is provided with tube-forming holes, and the conveyor belt 5 is rolled up into a tube shape on both sides after passing through the tube-forming holes. The tube-forming support 31 plays an auxiliary role in rolling up the conveyor belt 5 into a tube shape.

When the tube forming trolley 6 runs to the guide plate 9, the rotary rod 11 contacts the protrusion 91. Under the action of the protrusion 91, the rotary rod 11 rotates and opens. Under the limiting action of the guide plate 9, the tube forming trolley 6 runs to the radially opposite side of the reversing wheel 17 (return section). After the tube forming trolley 6 leaves the position of the guide plate 9, the rotary rod 11 automatically returns to the center under the action of the cam spring mechanism, and wraps the tube forming conveyor belt 5 of the return trip and maintains its tube forming shape.

[0035] The working principle of this utility model conveyor is as follows: The guide wheels 12 on both sides of the rotating rod 11 of the tube forming trolley 6 run on the track cable 7. The conveyor belt 5 maintains a tubular shape inside the tube forming trolley 6 and unfolds after running to both ends of the reversing mechanism 4.

Under the limiting action of the guide plate 9, the tube forming trolley 6 runs to the radially opposite side of the reversing wheel 17 (return section). After the tube forming trolley 6 leaves the position of the guide plate 9, the rotating rod 11 automatically returns to the center under the action of the cam spring mechanism and wraps the returning tubular conveyor belt 5 and maintains its tubular shape.

[0036] This invention is particularly suitable for mines, ports, large factories, and other locations requiring long-distance, high-volume raw material transportation. Compared to existing tubular conveyors, it features a lighter structure and lower energy consumption. This cable-stayed tubular conveyor uses a load-bearing cable and track cable 7 as the "aerial track," replacing the traditional rigid support. It can cross obstacles such as valleys, rivers, and roads, reducing earthwork and protecting the ecological environment. Compared to ordinary tubular conveyors, it utilizes a cableway structure to achieve large-span transportation and can be applied to material transportation in complex terrain and over obstacles. It enables long-distance, straight-line, single-transfer transportation, replacing the traditional model of multiple short-distance conveyors plus transfer stations, reducing transfer station construction costs, material transfer losses, and dust pollution, and improving system reliability. The cable structure is lighter than the traditional tubular conveyor frame structure 3, reducing the cost of steel structure raw materials, transportation costs, and foundation construction costs, resulting in a lower overall cost. In addition, since the rolling friction resistance of the tube forming trolley 6 on the steel cable is small, the use of steel cable transportation reduces friction and wear between components, significantly reducing overall energy consumption. It also has fewer moving parts and is standardized, making maintenance and inspection convenient and reducing life cycle costs.

[0037] The lightweight nature of this utility model's cable-stayed structure provides the physical basis for achieving long-span transportation and reducing foundation costs. Its lightweight structure allows for more economical long-distance erection. The simple structure and low-friction operation result in lower energy consumption, while fewer mechanical parts make maintenance easier, thus reducing overall life-cycle operating costs.
