Description

Technical Field

[0001] The invention relates to the technical field of cableway transportation, in particular to a small-sized mobile low-altitude iron chain system. Background Art

[0002] Cableway transportation is a means of transporting goods, people or power between two or more fixed support points by means of steel cables, mechanical equipment and energy. Cableway transportation mainly includes two types: cable transportation and aerial transportation. Cable transportation uses steel cables to move vehicles or containers along fixed tracks or lines, such as cable cars, which can be divided into towing and pushing types. Aerial transportation usually includes aerial cable cars and aerial cranes.

[0003] In the prior art, the ropeway transportation mode has been rapidly developed in China, but the development field is limited to passenger ropeways in tourist attractions, large freight ropeways, etc., and there are few ropeway design solutions for agricultural production and forestry transportation. Usually, the ropeway transportation mode is: erecting a high-altitude steel cable, and mounting a crane on it, and driving the steel cable to move through a winch to pull the crane to move; however, this design solution has a complex structure, a long construction period, huge costs, and damages the environment; therefore, it is very difficult to erect ropeways in most mountainous areas and forests in my country for agricultural production or regional transportation, resulting in most mountainous and forest areas still using the traditional transportation method of carrying goods on shoulders and backs. Summary of the invention

[0004] The purpose of the present invention is to provide a small-sized mobile low-altitude iron chain system, which has the advantages of simple structure, high flexibility and short construction period; and can arbitrarily plan and change the cableway running path according to demand.

[0006] A small-scale mobile low-altitude iron chain system comprises an iron chain and a guide bracket, wherein the iron chain is composed of iron rings interlocked in pairs, a steering mechanism is provided on the guide bracket, the iron chain is arranged into a circular transport path required for transportation through the guide bracket, a plurality of hooks are provided on the iron chain, the iron chain is meshed with a driving wheel, the driving wheel is connected to a power source through a driving shaft, a continuous groove is provided on the driving wheel, and the concave-convex iron chain formed by the iron rings interlocked in pairs is meshed with the continuous groove.

[0007] Through the above technical scheme, a number of guide brackets serve as the supporting body of the cableway; the steering mechanism changes the running direction of the iron chain, and the running path of the cableway can be arbitrarily planned and changed according to needs; a number of guide support rods are distributed along a ring, and the steering mechanism makes the iron chain run in a ring, thereby achieving the purpose of closed-loop operation of the entire device.

[0011] The side wall of the steering wheel is provided with a first limiting groove.

[0012] Through the above technical solution, the steering wheel is used to support the iron chain and guide the iron chain to run; the reversing assembly cooperates with the steering wheel to change the running direction of the iron chain; the first limit groove is used to accommodate the iron chain and limit the iron chain so that the iron chain runs along a preset path.

[0013] In one embodiment of the present invention, the reversing assembly includes a reversing frame fixed on the mounting frame, a limiting wheel rotatably connected to the reversing frame, and two supporting wheels rotatably connected to the reversing frame;

[0014] The side wall of the limiting wheel is provided with a second limiting groove;

[0015] The two support wheels are arranged opposite to each other, and the limiting wheel is located just above the center line between the two support wheels.

[0016] Through the above technical solution, the limiting wheel is used to limit the iron chain, and the supporting wheel is used to support the iron chain, thereby improving the mounting capacity of the cableway; the channel formed by the limiting wheel and the two supporting wheels is used to limit the iron chain and make the iron chain run along a preset path to achieve the purpose of changing the running direction of the iron chain.

[0017] In one embodiment of the present invention, the bottoms of the two support wheels are inclined outwards.

[0020] The fixed frame and a plurality of guide brackets are distributed in a ring shape.

[0021] Through the above technical solution, the driving mechanism is used to drive the iron chain to circulate.

[0033] Example 1: Please refer to Figure 1 The present invention provides a small-sized mobile low-altitude iron chain system, comprising an iron chain 1 and a guide bracket 2, wherein the iron chain 1 is composed of iron rings interlocked in pairs, and a steering mechanism 3 is provided on the guide bracket 2. The iron chain 1 is arranged into a circular transport path required for transportation through the guide bracket 2, and is characterized in that: the iron chain 1 is meshed with a driving wheel 4, and the driving wheel 4 is connected to a power source 6 through a driving shaft 5, and a continuous groove 401 is provided on the driving wheel 4, and the concave-convex iron chain 1 formed by the interlocking of the iron rings in pairs is meshed with the continuous groove 401;

[0034] A plurality of hooks 7 are welded on the iron chain 1 for hooking goods to facilitate the transportation of goods.

[0035] See also Figure 2 , Figure 3 and Figure 4 The steering mechanism 3 includes a mounting frame 301 welded and fixed on the guide bracket 2, a steering wheel 302 rotatably connected to the mounting frame 301, and a reversing assembly 303 located on both sides of the steering wheel 302; the steering wheel 302 rotates in the horizontal direction, and a first limiting groove is provided on the side wall of the steering wheel 302;

[0036] The steering wheel 302 and the two reversing components 303 are not in the same straight line, and the iron chain 1 is introduced from one reversing component 303, passes through the first limiting groove, and is led out from the other reversing component 303 to achieve the change of running direction;

[0037] The reversing assembly 303 includes a reversing frame 3031 bolted to the mounting frame 301, a limiting wheel 3032 rotatably connected to the reversing frame 3031, and two supporting wheels 3033 rotatably connected to the reversing frame 3031; the limiting wheel 3032 rotates perpendicularly to the rotation direction of the steering wheel 302;

[0038] The reversing frame 3031 includes a U-shaped frame and support plates integrally formed on both sides of the U-shaped frame and extending downward. One side of the U-shaped frame is bolted to the mounting frame 301, and the limiting wheel 3032 rotates on the other side of the U-shaped frame; the two support plates are arranged opposite to each other, and the two support wheels 3033 are respectively connected to the two support plates in a rotation manner, so that the two support wheels 3033 are also arranged opposite to each other; the bottoms of the two support plates are inclined outward, so that the bottoms of the two support wheels 3033 are also inclined outward; as the iron chain 1 runs, the hook 7 and the goods can pass through the steering mechanism 3 without hindrance;

[0039] The side wall of the limiting wheel 3032 is provided with a second limiting groove; the limiting wheel 3032 is located directly above the center line between the two supporting wheels 3033; a passage is formed between the limiting wheel 3032 and the two supporting wheels 3033 at the same height as the first limiting groove and through which the iron chain 1 passes;

[0040] When the iron chain 1 is located in the passage and is running, the upper part of the iron chain 1 is located in the second limiting groove, and the two supporting wheels 3033 are used to support both sides of the iron chain 1, thereby limiting the running iron chain 1 and preventing the position of the iron chain 1 from being offset.

[0041] The guide bracket 2 is fixed on the foundation by casting or by anchor bolts, and a plurality of guide brackets 2 are distributed in a ring shape, so as to achieve the purpose of closed-loop operation of the entire device;

[0042] Conventional power source selection is mainly based on multiple factors such as the needs of the application scenario, environmental impact, cost, technical feasibility, etc., such as fossil fuel engines, electric motors, hydraulic motors, etc. Since the iron chain system has the characteristics of rapid construction and rapid transportation, the power source 6 selected during the construction process is generally also applicable, and can be disassembled and carried at any time, or it can be moved and carried in the transportation environment as a power source 6. At the same time, the transported goods are relatively heavy, so the power source 6 also needs to ensure sufficient power during transportation and have a large driving power, so as to ensure the normal operation of the iron chain system. The power source 6 in this embodiment can be an electric motor or a diesel (gasoline) engine. The electric motor and the diesel (gasoline) engine have a common feature that both can be quickly disassembled and installed, have high compatibility, and have low cost. This greatly improves the layout efficiency of the iron chain system and saves the use cost of the device. At the same time, both can adapt to various different transportation environments and ensure normal operation in different transportation environments (such as mountainous areas).

[0043] A bearing seat is bolted on the support frame for fixing the drive shaft 5, and a bearing connected to the drive shaft 5 is installed in the bearing seat; the drive wheel 4 is fixedly connected to the drive shaft 5, and the drive shaft 5 drives the gear drive wheel 4 to rotate, thereby driving the iron chain 1 to reciprocate.

[0044] Example 2: Please refer to Figures 1 to 4When building a cableway in a mountainous area, a tree can be used as a guide bracket 23. By setting a clamp on the tree and welding the reversing assembly 303 to the clamp, the cableway can be built; and the clamp can be removed after use, which is suitable for temporary transportation and easy to disassemble and relocate.

[0045] In summary, the present invention can arbitrarily plan and change the cableway running path according to demand; it has high flexibility and mobility as a whole, short construction period, strong carrying capacity, convenient maintenance, and is very suitable for temporary handling operations in mountainous and hilly areas, without the need for temporary road repairs, etc., and has less damage to the environment; because it is a low-altitude operation, it is very convenient for loading and unloading, and the overall safety is high, replacing the traditional carrying method of shoulder-carrying and back-carrying, and effectively solving the problem of heavy object handling in mountainous and hilly areas. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
