Description

Technical Field

[0001] This utility model relates to the field of cableway transportation safety protection technology, and in particular to a cableway transportation equipment rope breakage locking structure. Background Technology

[0002] The transportation of agricultural products in mountainous and hilly areas has long been constrained by terrain. Cableway transportation, with its advantages of traversing complex terrain, minimal environmental impact, and stable operation, has been gradually applied to agricultural product transportation in mountainous areas. Existing agricultural cableway transportation equipment is mainly based on structural improvements of traditional freight cableways or monorail hoists. The core components include a load-bearing steel cable, a winch, support frames, and baskets or cargo boxes for loading agricultural products. The winch provides traction, driving the load-bearing steel cable to move the baskets or cargo boxes between the supports to complete the material transportation.

[0003] However, existing agricultural cableway transport equipment has key technical shortcomings in terms of safety protection: Due to the harsh mountainous environment, the cableway's traction components (such as traction cables, winches, and cable connectors) are subject to long-term erosion from wind and rain, fluctuations in material loads, and alternating stress caused by terrain undulations, making them prone to wear, corrosion, and even breakage. Furthermore, existing equipment lacks effective anti-slip protection mechanisms. When the winch breaks, causing the equipment to lose traction, the baskets or cargo boxes loaded with agricultural products will slide at high speed along the cableway under gravity. Such falls not only cause severe damage to agricultural products, directly harming farmers' economic income, but may also collide with farmland, roads, or surrounding structures below, and even cause personal injury or death. Summary of the Invention

[0004] The technical problem this utility model aims to solve is to provide a rope breakage locking structure for cableway transportation equipment. When the winch traction rope suddenly breaks and loses traction, it relies on the weight of the basket to lock in place, providing emergency braking and suspension to prevent damage caused by the cableway trolley losing control and falling at high speed. The purely mechanical structure achieves direct transmission of force and motion, providing a direct mechanical protection mechanism that is more direct and responds more quickly. The overall structure of the device is easy to assemble and disassemble, structurally stable, requires no external force monitoring, and uses the breakage of the winch traction rope as a reaction mechanism, making it fast, efficient, safe, and stable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rope breakage locking structure for cableway transportation equipment, including a cableway trolley frame. The cableway trolley frame includes a U-shaped bracket with an open bottom. A main frame plate is welded to one side of the U-shaped bracket, and a bottom plate is welded to the bottom of the main frame plate. The U-shaped bracket is equipped with a locking and protective anti-detachment pulley structure and a U-shaped brake frame with an open bottom. The top of the U-shaped brake frame is equipped with a first adjusting screw that penetrates the U-shaped bracket. The first adjusting screw is equipped with two fastening nuts that clamp the U-shaped bracket from the top and bottom. The main frame plate is equipped with a slot, and the bottom plate is equipped with an installation slot. A hook is equipped in the installation slot, and a limiting rod that cooperates with the installation slot is provided at the top of the hook. The bottom plate is connected to the top plate by multiple mounting bolts. The top plate is equipped with a locking slot that cooperates with the slot and an adjusting structure. The adjusting structure is linked with a second hanging rod set on the hook through a weight-limiting spring. The limiting rod is linked with the locking and protective anti-detachment pulley structure through a brake rope.

[0006] In a preferred embodiment, the brake rope has a protective sleeve.

[0007] In a preferred embodiment, the locking and protective anti-derailment pulley structure includes two clamping plates located inside the U-shaped bracket. The two clamping plates are hinged to the U-shaped bracket via a connecting rod. Limiting baffles and cable wheels are symmetrically provided at both ends of the two clamping plates. A locking structure connected to the brake rope is provided on one side of the clamping plate.

[0008] In a preferred embodiment, the locking structure includes support arms symmetrically welded to one side of the clamping plate, a positioning arm welded between the two support arms, the positioning arm engaging with the positioning slot on the caliper clamping arm, the two clamping arms of the caliper being connected by a compression spring, a limit block inserted at the intersection of the two clamping arms of the caliper, and the limit block being connected to the limit rod by a brake rope.

[0009] In a preferred embodiment, the size of the positioning slot is larger than the size of the positioning arm. In a preferred embodiment, the support arm is provided with a guide arm, which is connected to the protective sleeve.

[0010] In a preferred embodiment, the adjustment structure includes an adjustment frame welded to the top plate, an adjustment plate that is matched with the adjustment frame for limited movement, a second adjustment screw penetrating the top of the adjustment frame at the top of the adjustment plate, an adjustment nut on the second adjustment screw, and first hanging rods at both ends of the adjustment plate, the first hanging rods being connected to the second hanging rods via weight-limiting springs.

[0011] The rope breakage locking structure for cableway transportation equipment provided by this utility model has the following beneficial effects by adopting the above structure: (1) When the winch traction rope suddenly breaks and loses traction, it relies on the weight of the basket to lock and brake urgently to stop, thus avoiding damage caused by the overall loss of control of the cable car and high-speed slippage. (2) Pure mechanical structures realize the direct transmission of force and motion, and the direct mechanical protection mechanism is more direct and responds more quickly; (3) The overall structure of the device is easy to disassemble and assemble, the structure is stable, no external force monitoring is required, and the reaction mechanism is based on the breakage of the winch traction rope, which is fast, efficient, safe and stable.

Detailed Implementation

[0019] Example 1: like Figure 1-6As shown, the core component of the cableway transportation equipment's broken rope locking structure includes a cableway trolley frame 1. This trolley frame 1 serves as the overall installation and load-bearing foundation, and its structural design is adapted to the stress requirements of cableway transportation. The cableway trolley frame 1 includes a U-shaped bracket 3 with an open bottom. The U-shaped bracket 3 has a symmetrical structure, providing a stable mounting cavity for the subsequent locking and protection anti-detachment pulley structure 2 and U-shaped brake frame 8. A main frame plate 4 is vertically welded to one side of the U-shaped bracket 3. The main frame plate 4 is used to support the mounting and positioning of the slot 11 and related moving parts. A base plate 5 is horizontally welded to the bottom of the main frame plate 4. The base plate 5 and the main frame plate 4 form a vertical support structure, ensuring overall stress balance.

[0020] The U-shaped bracket 3 is equipped with a locking and protective anti-detachment pulley structure 2 and a U-shaped brake bracket 8 with a bottom opening. The U-shaped brake bracket 8 fits into the internal space of the U-shaped bracket 3, and its top is fixedly connected to the first adjusting screw 9. The installation height of the U-shaped brake bracket 8 within the U-shaped bracket 3 can be adjusted by the first adjusting screw 9. The top of the U-shaped brake bracket 8 is provided with the first adjusting screw 9 that passes through the U-shaped bracket 3. Two fastening nuts 10 are fitted on the first adjusting screw 9. The two fastening nuts are located on the upper and lower sides of the U-shaped bracket 3, respectively. By tightening the two fastening nuts 10, the height position of the U-shaped brake bracket 8 can be locked to ensure its stable installation.

[0021] A corresponding slot 11 is provided on the main frame plate 4, which is used to form a precise fit with the slot 22 on the top plate 7. A mounting groove 12 is provided in the middle area of ​​the bottom plate 5, which provides space for the installation and movement of the hook 18. The hook 18 is movably installed in the mounting groove 12. The hook 18 is used to suspend the basket loaded with agricultural products. The top of the hook 18 is integrally formed with a limiting rod 19 that is adapted to the mounting groove 12. The limiting rod 19 can move within a certain range along the mounting groove 12, while preventing the hook 18 from coming off.

[0022] The base plate 5 and the top plate 7 are fastened together by multiple mounting bolts 6, forming a closed mounting cavity, which ensures structural stability and facilitates disassembly and maintenance. One side of the top plate 7 has a locking slot 22 that precisely engages with the slot 11, allowing the top plate 7 to be positioned and fixed to the main frame plate 4. The other side of the top plate 7 has an adjustment structure for adjusting the preload of the weight-limiting spring 21 to accommodate different loading weight requirements. The adjustment structure is linked to the second hanging rod 20 on the hook 18 via the weight-limiting spring 21. The output end of the adjustment structure is also linked to the second hanging rod 20 on the hook 18 via the weight-limiting spring 21. Under normal conditions, the weight-limiting spring 21 maintains a preset tension, providing stable support for the hook 18. The limiting rod 19 is locked in conjunction with the locking and protection anti-detachment pulley structure 2 via the brake rope 30. The end of the limiting rod 19 is fixedly connected to one end of the brake rope 30, and the other end of the brake rope 30 is connected to the locking and protection anti-detachment pulley structure 2. The linkage locking function between the limiting rod 19 and the locking and protection anti-detachment pulley structure 2 is realized through the tension of the brake rope 30.

[0023] In a preferred embodiment, the brake rope 30 is fitted with a protective sleeve 29 on its outer side. The protective sleeve 29 can reduce the wear and corrosion of the brake rope 30 by the external environment, extend the service life of the brake rope 30, and ensure the smooth transmission of tension.

[0024] In a preferred embodiment, the locking and anti-detachment pulley structure 2 includes two clamping plates 23 symmetrically arranged inside the U-shaped bracket 3, with the two clamping plates 23 distributed in parallel. The middle positions of the two clamping plates 23 are hinged to the side wall of the U-shaped bracket 3 via a connecting rod 24, allowing the clamping plates 23 to rotate around the connecting rod 24 at a certain angle. Limiting baffles 25 and cable wheels 26 are symmetrically installed at both ends of the two clamping plates 23, respectively. The limiting baffles 25 restrict the lateral displacement of the cable wheels 26, which roll in conjunction with the carrying steel cable to reduce friction during transportation. A locking structure connected to a brake rope 30 is provided on one side of each clamping plate 23. This locking structure is fixedly connected to the end of the brake rope 30, and the opening and closing of the locking structure is controlled by changes in the tension of the brake rope 30.

[0025] In a preferred embodiment, the locking structure includes symmetrically arranged support arms 27 fixed to one side of the clamping plate 23. The two support arms 27 are symmetrically distributed to provide stable support for the positioning arm 32. A positioning arm 32 is fixedly connected between the free ends of the two support arms 27, and the positioning arm 32 is horizontally distributed. The positioning arm 32 passes through a positioning slot 34 opened on the clamping arm of the caliper 33 to form a sliding positioning fit, so that the two clamping arms of the caliper 33 can move within a certain range along the positioning arm 32 when clamping. The two clamping arms of the caliper 33 are arranged opposite each other, and the middle position of the two clamping arms is elastically connected by a contraction spring 35. The contraction spring 35 is in an extended state under normal conditions, so that the two clamping arms of the caliper 33 are kept in an inward clamping state. However, a limiting block 31 is embedded at the intersection of the two clamping arms of the caliper 33. The limiting block 31 is used to limit the clamping angle of the two clamping arms of the caliper 33 to avoid directly clamping the cable-bearing cable. The limiting block 31 is connected to the limiting rod 19 via the brake rope 30. The middle part of the limiting block 31 is fixedly connected to the other end of the brake rope 30. The limiting block 31 and the limiting rod 19 move synchronously through the tension of the brake rope 30.

[0026] In a preferred embodiment, the inner diameter of the positioning groove 34 is slightly larger than the outer diameter of the positioning arm 32. This ensures that the clamping arm of the caliper 33 moves smoothly along the positioning arm 32 when clamping, preventing jamming, and also avoids excessive shaking during movement, thus ensuring positioning accuracy.

[0027] In a preferred embodiment, the support arm 27 is provided with an outwardly extending guide arm 28 at the middle position. The free end of the guide arm 28 is fixedly connected to the end of the protective sleeve 29, which guides and limits the brake rope 30, preventing the brake rope 30 from getting tangled or deviating during movement.

[0028] In a preferred embodiment, the adjustment structure includes an adjustment frame 13 fixedly installed on the upper surface of the top plate 7. The adjustment frame 13 has a closed frame structure, providing limited movement space for the adjustment plate 14. The adjustment plate 14 is movably disposed inside the adjustment frame 13, slidingly engaging with the inner wall of the adjustment frame 13, and can move up and down along the vertical direction of the adjustment frame 13. A second adjustment screw 15 is fixedly connected to the middle of the upper surface of the adjustment plate 14. The second adjustment screw 15 extends vertically upward through the top wall of the adjustment frame 13 to the outside of the adjustment frame 13. An adjustment nut 16 is threaded onto the second adjustment screw 15, fitting against the upper surface of the adjustment frame 13. Rotating the adjustment nut 16 drives the second adjustment screw 15 to move the adjustment plate 14 up and down, thereby adjusting the preload of the weight-limiting spring 21. Symmetrically arranged outwardly extending first hanging rods 17 are provided at both ends of the adjustment plate 14, and the first hanging rods 17 are used to connect to the upper end of the weight-limiting spring 21. The first hanging rod 17 is connected to the second hanging rod 20 through a weight-limiting spring 21. Each first hanging rod 17 is connected to the second hanging rod 20 on the hook 18 through a corresponding weight-limiting spring 21. The two weight-limiting springs 21 are symmetrically distributed to ensure that the hook 18 is subjected to balanced force, and at the same time realize the elastic linkage between the adjustment structure and the hook 18.

[0029] Example 2: like Figure 1-6 The working principle of this utility model is as follows: When the winch pulls the cableway trolley frame 1 along the carrying steel cable, the cargo basket loaded with agricultural products is suspended on the hook 18. At this time, the weight-limiting spring 21 is in its initial preset state. The cargo basket is mainly tensioned by the winch traction rope. Through the connection between the first hanging rod 17 and the second hanging rod 20, a stable upward pulling force is provided to the hook 18, causing the hook 18 to drive the limiting rod 19 to suspend above the mounting groove 12 and maintain its initial position. The limiting rod 19 applies a continuous pulling force to the limiting block 31 of the locking structure through the brake rope 30. This pulling force is less than the elastic force of the contraction spring 35 applied to the friction force generated between the two clamping arms and the limiting block 31. The limiting block 31 will not be pulled out, and the two clamping arms of the caliper 33 cannot close under the contraction elastic force of the contraction spring 35. At this time, the caliper will not contact the carrying steel cable. At the same time, the cableway wheel 26 rolls with the carrying steel cable, and the limiting baffle 25 restricts the lateral displacement of the cableway wheel 26, ensuring that the cableway trolley frame 1 moves smoothly along the carrying steel cable and completes the normal transportation of agricultural products.

[0030] When the winch traction rope breaks unexpectedly and the basket loses traction, the basket falls downwards under its own weight and the weight of the load. The deformation force of the weight-limiting spring 21 does not exceed half of the weight of the basket and its fully loaded state. At this time, the weight-limiting spring 21 deforms, and the basket moves downwards under the action of gravity, causing the tension of the brake rope 30 to increase instantaneously. This causes the limit block 31 to be pulled out in conjunction with the release of the elastic force of the contraction spring 35, which pulls the two clamping arms of the caliper 33 to quickly close in the middle, tightly clamping the load-bearing steel cable and forming the first mechanical lock. The closing action of the caliper 33 clamps the carrying steel cable at the accurate position through the cooperation of the positioning slot 34 and the positioning arm 32. Since the inner diameter of the positioning slot 34 is slightly larger than the outer diameter of the positioning arm 32, it ensures the smooth movement of the clamping arm of the caliper 33 along the positioning arm 32 when clamping, without jamming, and also avoids excessive shaking during movement, ensuring positioning accuracy. Finally, the cableway carriage 1 quickly decelerates and suspends on the carrying steel cable to prevent damage to agricultural products and safety accidents caused by the high-speed slippage of the basket.

[0031] The beneficial effects of this utility model are as follows: When the winch traction rope suddenly breaks and loses traction, it relies on the weight of the basket to lock and brake urgently, preventing the cable car from losing control and falling at high speed and causing injury; the pure mechanical structure realizes the direct transmission of force and motion, and the direct mechanical protection mechanism is more direct and responds more quickly; the overall structure of the device is easy to disassemble and assemble, the structure is stable, no external force monitoring is required, and the reaction mechanism is based on the breakage of the winch traction rope, which is fast, efficient, safe and stable.
