Mountain agricultural product cableway transportation equipment linkage safety protection device

Abstract

The safety protection device for cableway transportation of mountain agricultural products includes a cableway trolley pulley structure and a trolley bracket. A cableway trolley braking structure is welded to the bottom of the pulley structure, and a broken rope protection hook is welded to the bottom of the braking structure. The broken rope protection hook is detachable and assembles with the trolley bracket. Using this structure, the linkage between the braking device and the cargo basket hook enables suspension braking at any point during cableway transportation, and allows for the raising and lowering of the cargo basket, facilitating free loading and unloading of mountain agricultural products. After the cargo basket rises to the suspended position, the cableway brake lock can be quickly released under stable hooking conditions, allowing for a smooth and timely switch between traction and movement states. If the traction rope breaks, the hook structure is stressed, and the weight of the cargo basket and the goods themselves can quickly complete the braking lock, preventing the entire cableway from sliding uncontrollably to a lower point when traction is lost, significantly improving the safety of cableway transportation.

Description

Technical Field

[0001] This utility model belongs to the technical field of cableway transportation equipment, and specifically relates to a linkage safety protection device for cableway transportation equipment for mountain agricultural products. Background Technology

[0002] In mountainous and hilly areas, the complex terrain and significant elevation changes make the construction of transportation infrastructure both costly and challenging. Farmers in these areas face the severe problem of transporting agricultural products down the mountain. Traditional transportation methods primarily include manual carrying, animal power transport, and the use of agricultural tricycles and other mechanized transport after constructing simple mountain roads. These methods generally suffer from low efficiency, high labor intensity, high transportation costs, and severe susceptibility to weather and road conditions. Especially during the rainy season, muddy and slippery roads greatly increase the risk of accidents, and agricultural products are easily damaged during bumpy transport, severely impacting their market value and farmers' economic returns.

[0003] To address the aforementioned issues, cableway transportation technology has recently been explored for application in the transportation of agricultural products from mountainous areas. Cableway transportation offers advantages such as requiring minimal land occupation, causing minimal environmental damage, traversing complex terrain, and providing relatively stable operation, making it theoretically well-suited for mountainous environments. Existing technologies include several cases of using freight cableways or monorail hoists for timber transportation in forest areas or for transporting mining materials. These devices typically employ simple basket or cargo box structures, moving between supports via load-bearing steel cables and winches.

[0004] However, in the event of a breakage in the winch traction rope, the existing cableway transport equipment becomes uncontrollable, posing a significant safety hazard and sometimes even causing serious production accidents. In the field of cableway transport, current technology can only achieve real-time monitoring and intelligent early warning through data collection by sensors and cameras, or control emergency drive devices through electrical controls, but it cannot provide rapid and safe braking. Therefore, existing cableway transport equipment cannot meet the comprehensive requirements of safety, freshness, efficiency, and environmental friendliness for the transport of mountain agricultural products. There is an urgent need to develop a cableway transport system specifically designed for the characteristics of mountain agricultural products. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a linkage safety protection device for mountain agricultural product cableway transportation equipment. It achieves direct transmission and interlocking of force and motion through a purely mechanical structure (tension spring, cable, caliper). Through mechanical linkage, it directly triggers the braking of the cableway trolley on the carrying cable, breaking away from the passive monitoring mode that relies on electric sensors. It creates an active, direct mechanical protection mechanism that does not rely on external power and complex control. It deeply couples the cargo basket status and the trolley braking, two originally potentially independent safety links, providing a more direct and faster-responding local terminal overload protection scheme. It provides a specific solution for a clear and dangerous safety hazard.

Through the linkage between the braking device and the cargo basket hook, the suspension braking at any point during cableway transportation is achieved, and the cargo basket can be raised and lowered, facilitating free loading and unloading of mountain agricultural products.

[0019] In a preferred embodiment, the broken rope protection hook 3 includes a base plate 48 welded and fixed to the bottom of the support plate 21. The base plate 48 is fixedly connected to the mounting plate 49 by multiple second mounting bolts 50. The trolley bracket 4 is installed between the base plate 48 and the mounting plate 49. The base plate 48 is provided with an adaptation groove 52, and a hook structure is provided in the adaptation groove 52. The mounting plate 49 is provided with an adjustable load structure and a limiting mounting buckle 51, which cooperates with the limiting mounting port 27 provided at the bottom of the support plate 21. The assembly and disassembly are convenient and flexible, and the load structure can be adjusted to adapt to different load weights.

[0020] In a preferred embodiment, the hook structure includes symmetrically arranged hook plates 59. A fixing rod 60, which fits into the limiting groove 52, is welded to the top of each hook plate 59. Third mounting bolts 61 are provided on both sides of the bottom of each hook plate 59.

A hook tongue 67 is provided between the symmetrically positioned hook plates 59. An arc-shaped arm 68 is provided at the top of the hook tongue 67, and the end of the arc-shaped arm 68 away from the hook tongue 67 is hinged to the connecting pin 66. A third guide edge 69, which fits into the first guide edge 63 and the second guide edge 64, is provided at the bottom of the hook tongue 67. This ensures stable hooking, allows free entry, and guarantees stable hooking again after the basket moves up and down.

[0021] In a preferred embodiment, the adjustable load structure includes an adjusting frame 53 welded and fixed to the mounting plate 49. The adjusting frame 53 contains an adjusting bracket 54 that is positioned and fitted therewith. The adjusting bracket 54 has a second adjusting screw 55 penetrating the top of the adjusting frame 53, and a fourth fastening nut 56 on the second adjusting screw 55. First hanging rods 57 are symmetrically welded to both sides of the adjusting bracket 54. The first hanging rods 57 are connected to a second hanging rod 65 mounted on the hook plate 59 via a weight-limiting spring 58. This ensures that when the winch traction rope is disconnected, the hook structure remains stable under downward force, simultaneously triggering an emergency braking mechanism.

[0022] In a preferred embodiment, the hook tongue 67 is equipped with a linkage buckle 70, which is connected to a fixing ring 73 on the top block 72 via a traction rope 74. This facilitates the unhooking of the cargo basket after the cableway has come to a stop, allowing it to be raised and lowered to accommodate loading of mountain goods.

[0023] In the preferred embodiment, the fixed rod 60 is fixedly connected to one end of the brake cable 71. The brake cable 71 is covered with a protective tube 20, which is connected to the protective frame 13 via a support frame 19. The protective frame 13 is located on one side of the limiting mounting plate 11 and has a positioning strip 14 that passes through the positioning opening 16 on the clamping arm of the brake clamp 15. A locking block 18 for locking is inserted at the junction of the clamping arms of the brake clamp 15. The locking block 18 is fixedly connected to the other end of the brake cable 71. A return spring 17 for retracting the clamping arms on both sides is provided at the top of the clamping arms of the brake clamp 15. The emergency braking mechanism after the winch traction rope is disconnected greatly improves the safety of the cableway transportation equipment. At the same time, the size of the positioning buckle 16 is larger than the size of the positioning strip 14, ensuring that the clamping arms of the brake clamp 15 have sufficient clamping freedom and that the clamping jaws of the brake clamp will not disengage from the position of the carrying cableway due to shaking during cableway transportation, thus maintaining stable clamping of the carrying cableway at all times to achieve locking protection.

[0024] In a preferred embodiment, the sports car bracket 4 includes a U-shaped channel frame 75. The bottom of the U-shaped channel frame 75 is open and has a first through hole 80 for the vertical movement of the reset slide rod 38, a second through hole 79 for the brake cable 71 to pass through, and a side arm 76. The bottom of the U-shaped channel frame 75 is provided with multiple traction wheels 77, and the side arm 76 is provided with a second cable wheel 78. The structure is stable and easy to assemble and disassemble.

[0025] Example 2: like Figure 1-14 The working principle of this utility model is as follows: Step 1: In the working state, when the cable-driven cargo basket moves to the loading position and needs to stop, the electric push rod device 24 extends via remote control. During the extension process, the top block 72 pushes the T-shaped trolley brake support arm 36 upward from bottom to top. After the T-shaped trolley brake support arm 36 moves to the top, it cooperates with the U-shaped brake frame 8 to clamp the load-bearing steel cable. After braking, the electric push rod device 24 retracts to the initial state. Step 2: After the T-shaped sports car brake support arm 36 moves to the top, one end of the clamping plate 45 is fixedly installed on the mating plate 43, and the other end of the clamping plate 45 is kept at a downward angle under the pressure of the return spring 42, so that the clamping through groove 46 locks the moving arm position of the T-shaped sports car brake support arm 36. Step 3: As the electric push rod device 24 is pushed out to the farthest end, the traction rope 74 drives the hook tongue 67 to rotate, the hook structure opens, and the cargo basket is released from the hook structure and locked, and can descend and move as the winch traction rope is extended. Step 4: After loading and unloading goods, the cargo basket rises with the traction rope of the winch. When it moves to the position of the hook structure, it is aligned with the hanging groove 62 under the guidance of the first guide edge 63 and the second guide edge 64. It is pushed open by the third guide edge 69 and squeezed open the hook tongue 67 to enter the hanging groove 62. After entering the hanging groove 62, the hook tongue 67 is automatically reset with the cooperation of the arc arm 68. Step 5: After the cargo basket is suspended in the hanging slot 62 and the hook tongue 67 is reset, the winch traction rope continues to wind up. When the suspended position of the cargo basket touches the trigger head 39, the reset slide bar 38 moves up. Under the action of the top block 41, the clamping plate 45 returns to the horizontal state. Since the length of the clamping through slot 46 is greater than the width of the T-shaped trolley brake support arm 36, the T-shaped trolley brake support arm 36 falls back quickly under the action of gravity, releasing the clamp on the load-bearing steel cable, so that the cableway trolley is released from the brake positioning state and resumes the change of direction movement state of the winch traction rope winding and moving, changing from the vertical direction of cargo basket lifting and lowering to the cableway trolley moving along the load-bearing cableway. Step Six: The deformation of the weight-limiting tension spring 58 is applied to the cargo basket. Under normal conditions, the cargo basket is mainly supported by the winch traction rope. When the winch traction rope is disconnected, the overall downward gravity of the cargo basket and the goods is greater than the deformation force of the weight-limiting spring 58. The entire hook structure moves downward. With the cooperation of the fixed rod 60 and the adaptive through groove 52, the hook structure will not detach from the base plate 48. However, as the hook structure moves downward, the brake cable 71 is quickly tightened. The brake cable 71 drives the locking block 18 to move and be pulled out. At this time, the brake clamp 15 clamps the load-bearing steel cable under the action of the return spring 17 to complete the emergency braking and prevent the cableway equipment from sliding and falling due to the broken rope.

[0026] The beneficial effects of this utility model are as follows: By linking the braking device with the cargo basket hook, the suspension braking at any point during cableway transportation can be achieved, raising and lowering the cargo basket, enabling free loading and unloading of mountain agricultural products below the cableway line after harvesting; after the cargo basket rises to the position of the broken rope protection hook, the cargo basket can be quickly released from the cableway trolley braking structure lock in a stable hooked state, and the traction movement state can be switched smoothly and timely, ensuring stability and safety; in the event that the winch traction rope breaks during operation, the cargo basket will not fall off the broken rope protection hook as a whole, and the hook structure will be stressed, the weight limit spring will be stretched and fall, and the emergency braking device of the cableway trolley will be triggered through the brake cable, quickly completing the locking of the cableway trolley, preventing the entire cableway transportation device from sliding uncontrollably to a lower point when the winch traction force is lost, significantly improving the safety of cableway transportation, ensuring that the trolley does not slip and the cargo basket does not fall.
