Description

Technical Field

[0001] This invention relates to the field of mining cableway technology, specifically a turning device for a mining fixed grip cableway. Background Technology

[0002] In complex terrain environments such as mines, fixed-grip cableways are widely used for personnel and material transport due to their simple structure, convenient maintenance, and high transport efficiency. However, traditional fixed-grip cableways typically require straight lines or smooth curves with minimal radius of curvature. This is mainly because the fixed grip and wire rope are rigidly clamped together, resulting in severe mechanical collisions and friction between the grip and the guide wheel when the line curves.

[0003] Existing technologies face the following main problems and shortcomings when dealing with cableway turns, especially sharp turns: 1. At bends, the change in cable direction causes frequent collisions between the fixed cable grip and the guide wheel. This not only leads to rapid wear of the cable grip and wheel bushings, shortening the equipment's lifespan, but also causes severe cable vibration, seriously affecting ride comfort and operational safety.

[0004] 2. At bends, cables are subjected to lateral forces pointing towards the center of the bend. For cables located on the inside of the bend, due to the lack of effective radial restraint, they are highly susceptible to detaching from the sheave under the influence of lateral forces, resulting in a "detour" failure. Once a detour occurs, it can not only lead to a complete shutdown of the line but also cause secondary injuries to equipment and personnel, especially in high-risk environments such as mines, where the consequences could be disastrous.

[0005] 3. Traditional turning designs typically require a large turning radius or multiple distributed guide wheel sets, resulting in a bulky turning device that occupies significant space in tunnels or along the track. In space-constrained locations such as underground mines, this design is often difficult to implement, limiting the flexible layout of cableway lines.

[0006] 4. In existing technologies, there is usually a lack of real-time and reliable monitoring methods to detect whether the cable has come off at a bend. Problems are often only discovered after a cable come-off incident, making it impossible to provide timely warnings and stop the machine in the early stages of a fault, thus missing the best opportunity to prevent the accident from escalating. Summary of the Invention

[0007] To address the aforementioned shortcomings in existing technologies, the present invention aims to provide a turning device for fixed-grip cableways in mining applications. This device solves the problems of cable stability and guidance, anti-derailment protection, and equipment wear during turns, particularly large-angle, small-radius turns.

[0008] The technical solution adopted by the present invention to achieve the above objectives is as follows: a turning device for a mining fixed grip cableway, comprising an inner wheel set, an outer wheel set, and an anti-derailment protection component. The inner wheel set and the outer wheel set are respectively disposed on the inner and outer sides of the cableway turning point. Both the inner wheel set and the outer wheel set include multiple sets continuously arranged along the cableway turning point. The inner wheel set is used to support the inner cable arranged at the cableway turning point. The anti-derailment protection component is disposed on the inner side of the inner wheel set and is used to detect whether the inner cable has fallen off the inner wheel set. The outer wheel set is used to support the outer cable arranged at the cableway turning point. Fixed grips are mounted on the inner cable and the outer cable.

[0009] Based on the above technical solutions, in order to ensure that the inner wheel assembly, outer wheel assembly and anti-derailment protection components can be stably assembled and operated at the cableway turning points, so as to ensure that the inner and outer cables can operate stably to meet the transportation needs of personnel, the following technical solutions are provided.

[0010] It also includes a mounting beam erected at the turning cableway, the mounting beam being evenly arranged radially along the turning cableway, and the inner wheel set, outer wheel set, and anti-derailment protection assembly being assembled onto the mounting beam.

[0011] Based on the above technical solutions, in order to ensure that the inner wheel assembly can be stably assembled on the mounting beam and that the inner wheel assembly can effectively support and position the inner cable to achieve stable operation of the inner cable, the following technical solutions are provided.

[0012] The inner wheel assembly includes an assembly unit A and an upper anti-rope wheel and a lower anti-rope wheel assembled on the assembly unit A. The assembly unit A is assembled on the mounting beam and is used to adjust the assembly height and angle of the upper anti-rope wheel and the lower anti-rope wheel. The upper anti-rope wheel and the lower anti-rope wheel are respectively arranged on the upper and lower sides of the inner cable and are used to support and guide the inner cable.

[0013] Based on the above technical solutions, in order to ensure that assembly unit A can stably assemble the upper anti-rope wheel and the lower anti-rope wheel onto the installation crossbeam, and to effectively adjust the assembly height and angle of the upper anti-rope wheel and the lower anti-rope wheel, the following technical solutions are provided.

[0014] The assembly unit A includes a hanger A, an auxiliary hanger, an upper beam, a lower beam, and a steering head. The hanger A is fixedly assembled to the mounting beam. The auxiliary hanger is assembled to the hanger A and can be vertically adjusted relative to the hanger A. Both the upper beam and the lower beam are assembled to the auxiliary hanger. Steering heads are assembled at both ends of the upper beam and the lower beam. The steering heads can be rotated and adjusted relative to the upper beam and the lower beam. The upper anti-rope pulley is assembled to the steering head located on the upper beam, and the lower anti-rope pulley is assembled to the steering head located on the lower beam.

[0015] Based on the above technical solutions, in order to ensure that the upper anti-rope pulley arranged above the inner cable can effectively fit and position the inner cable, the following technical solution is provided.

[0016] The assembly unit A also includes a longitudinal adjuster A, which is assembled to the top of the auxiliary hanger and is used to adjust the upper limit of the height of the upper beam.

[0017] Based on the above technical solutions, in order to ensure that the outer wheel assembly can be stably assembled on the mounting beam and that the outer wheel assembly can effectively support and position the outer cable to achieve stable operation of the outer cable, the following technical solutions are provided.

[0018] The outer wheel assembly includes an assembly unit B and an outer anti-rope wheel and a supporting rope wheel assembled to the assembly unit B. The assembly unit B is assembled to the mounting beam and is used to adjust the horizontal position of the outer anti-rope wheel and the height position of the supporting rope wheel. The outer anti-rope wheel is arranged inside the outer cable, and the supporting rope wheel is arranged at the bottom of the outer cable.

[0019] Based on the above technical solutions, in order to ensure that assembly unit B can stably assemble the outer anti-rope wheel and the supporting rope wheel onto the installation crossbeam, and to effectively adjust the assembly position of the outer anti-rope wheel and the supporting rope wheel so as to effectively support the outer cable, the following technical solutions are provided.

[0020] The assembly unit B includes a hanger B and a mounting bracket. The hanger B is fixedly assembled to the mounting beam, and the mounting bracket is assembled to the hanger B and arranged in a horizontal direction. The two ends of the mounting bracket are equipped with the outer anti-rope pulleys, and the bottom of the hanger B is equipped with the rope support pulley.

[0021] Based on the above technical solutions, in order to effectively adjust the horizontal position of the outer anti-rope wheel and the height position of the support rope wheel, so as to ensure that the outer anti-rope wheel and the support rope wheel can effectively fit and position the outer cable, the following technical solutions are provided.

[0022] The assembly unit B further includes a lateral adjuster and a longitudinal adjuster B. The lateral adjuster is assembled to both ends of the mounting bracket and is used to adjust the horizontal position of the outer anti-rope wheel. The longitudinal adjuster B is assembled to the bottom of the hanger and is used to adjust the height position of the support rope wheel.

[0023] Based on the above technical solutions, in order to ensure that the anti-derailment protection component can be stably assembled on the installation beam, to achieve anti-derailment protection for the inner cable, and to provide a rapid warning when the inner cable falls off, the following technical solutions are provided.

[0024] The anti-rope slippage protection component includes a fixed bracket, a lifting bracket, a protective wheel, a limiter, and a protection sensor. The fixed bracket is mounted on the mounting beam, and the lifting bracket is mounted on the fixed bracket and can be vertically adjusted relative to the fixed bracket. The protective wheel is rotatably mounted on the bottom end of the lifting bracket. The limiter and the protection sensor are both mounted on the lifting bracket. The limiter is used to position the protective wheel, and the protection sensor is used to detect whether the protective wheel is rotating.

[0025] Based on the above technical solution, in order to ensure that the inner and outer cables can realize the function of passenger transfer, a passenger carrier is installed on the fixed gripper.

[0026] The beneficial effects of this invention are: 1. By setting continuously arranged inner and outer wheel sets on the inner and outer sides respectively, and cooperating with adjustable anti-rope wheels and deflection angles, a single wheel set can withstand a larger turning angle. This design effectively solves the problem of traditional cableways requiring a large turning radius, significantly saves valuable installation space in underground mines or complex terrains, and makes fixed-grip cableways more flexible in route layout.

[0027] 2. To address the problem of the inner cable easily detaching, this solution not only incorporates upper and lower anti-rope wheels on the inner pulley assembly to clamp and guide the inner cable, but also includes a specially added anti-detachment protection component. This component can monitor the operating status of the inner cable in real time. Once a tendency to detach or actual detachment occurs, the protection wheel is immediately triggered to rotate, the protection sensor quickly detects the signal, and an alarm is triggered to stop the machine. This dual protection design fundamentally eliminates the risk of equipment damage and personnel injury caused by cable detachment, significantly improving the operational safety of the system.

[0028] 3. By staggering the upper and lower anti-rope pulleys of the inner wheel assembly and the rope-supporting pulleys and outer anti-rope pulleys of the outer wheel assembly along the cable length, the fixed grip can smoothly transition from one set of pulleys to the next when passing through a bend, avoiding the continuous impact between the grip and the guide wheel in traditional designs. This eliminates the severe vibration of the cable, ensuring riding comfort, and significantly reduces wear on the grip and wheel bushings, extending the service life of the equipment.

[0029] 4. In the inner wheel assembly, both the upper and lower beams used to mount the upper and lower anti-rope wheels can rotate relative to the auxiliary hanger, and the upper beam has the freedom of lifting and lowering, limited by the longitudinal adjuster. This floating design allows the upper and lower anti-rope wheels to automatically follow the cable's movement when the fixed gripper passes by, even if it causes local undulations in the cable, maintaining a close fit with the cable at all times, thus ensuring the stability and reliability of the guide.

[0030] 5. In this solution, the wheel assembly and protective components are all mounted on a unified mounting beam using modular assembly units. Each assembly unit is designed with a multi-dimensional adjustment mechanism, which greatly facilitates on-site installation and alignment adjustments, effectively compensates for manufacturing errors and wheel liner wear, and enables the entire device to perfectly adapt to turning lines with different radii of curvature and installation heights.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0034] Please see Figure 1 , Figure 2 A turning device for a mining fixed grip cableway includes an inner wheel set 1, an outer wheel set 2, and an anti-derailment protection component 3. The inner wheel set 1 and the outer wheel set 2 are respectively arranged on the inner and outer sides of the cableway turning point. Both the inner wheel set 1 and the outer wheel set 2 include multiple sets continuously arranged along the cableway turning point. The inner wheel set 1 is used to support the inner cable 61 arranged at the cableway turning point. The anti-derailment protection component 3 is arranged on the inner side of the inner wheel set 1 and is used to detect whether the inner cable 61 has fallen off the inner wheel set 1. The outer wheel set 2 is used to support the outer cable 62 arranged at the cableway turning point. Fixed grips 4 are installed on the inner cable 61 and the outer cable.

[0035] The turning device provided in this solution is mainly used in cableway systems for personnel transportation in mines. It can also be applied to other cableway scenarios with turns along the route to provide personnel with a stable and reliable transportation vehicle.

[0036] It should be noted that the inner and outer sides of the cableway turns proposed in this solution are defined relative to the geometric center of the turn. That is, the side closer to the geometric center is the inner side of the cableway turn, and the side farther from the geometric center is the outer side of the cableway turn. For scenarios with continuous turns, such as S-shaped curves, since there are corresponding geometric centers on both sides of the curve, there will be a scenario where both inner wheel set 1 and outer wheel set 2 exist on one side of the cable.

[0037] The continuous arrangement of the inner wheel assembly 1 and the outer wheel assembly 2 ensures the stable installation and operation of the inner cable 61 and the outer cable 62. Due to the cable arrangement at the bend, the cable will exert a force pointing towards the geometric center. For the outer cable 62, the structural design of the outer wheel assembly 2 provides effective support, thus preventing the outer cable 62 from detaching from the outer wheel assembly 2. For the inner cable 61, the structural design of the inner wheel assembly 1 cannot completely guarantee that the inner cable 61 will not detach. Therefore, an anti-detachment protection component 3 is installed on the inside of the inner wheel assembly 1 to detect whether the inner cable 61 has detached from the inner wheel assembly 1.

[0038] The inner cable 61 and the outer cable 62 form a closed loop and are driven to run continuously by a winch. Therefore, the inner cable 61 and the outer cable 62 can run in opposite directions to form two transmission paths in the cableway, thereby driving the cable gripper to move stably.

[0039] This solution addresses the challenge of using the fixed grip 4 at cableway bends, making it particularly suitable for steep turns. By adjusting the rope-resistant angle and rope-pressing amount of the outer wheel assembly 2 and the inner wheel assembly 1, the achievable turning angle of a single wheel assembly can be adjusted, saving installation space at bends. It also prevents cable vibration and wear on the fixed grip 4 caused by impacts at bends. Furthermore, it avoids wire rope derailment at bends and reduces secondary injuries to equipment and personnel caused by derailment due to external forces.

[0040] To ensure that the inner wheel assembly 1, the outer wheel assembly 2, and the anti-derailment protection component 3 can be stably assembled and operated at the cableway bends, and to ensure that the inner cable 61 and the outer cable 62 can operate stably to meet the transportation needs of personnel, the following technical solutions are provided.

[0041] It also includes a crossbeam 5 erected at the turning cableway. The crossbeam 5 is evenly arranged radially along the turning cableway. The inner wheel set 1, the outer wheel set 2, and the anti-derailment protection component 3 are all assembled onto the crossbeam 5.

[0042] The mounting beam 5 can be arranged on the transmission path by direct anchoring or by support structure, and its arrangement density can be adjusted according to the geometric radius of the bend to ensure that the inner wheel set 1 and the outer wheel set 2 can effectively support and guide the outer cable 62 and the inner cable 61. Example 2

[0043] Please see Figures 1-4To ensure that the inner wheel assembly 1 can be stably assembled on the mounting beam 5 and to ensure that the inner wheel assembly 1 can effectively support and position the inner cable 61 so as to achieve stable operation of the inner cable 61, the following technical solution is provided.

[0044] The inner wheel assembly 1 includes an assembly unit A11 and an upper anti-rope wheel 12 and a lower anti-rope wheel 13 assembled on the assembly unit A11. The assembly unit A11 is assembled on the mounting beam 5. The assembly unit A11 is used to adjust the assembly height and angle of the upper anti-rope wheel 12 and the lower anti-rope wheel 13. The upper anti-rope wheel 12 and the lower anti-rope wheel 13 are respectively arranged on the upper and lower sides of the inner cable 61 and are used to support and guide the inner cable 61.

[0045] The assembly unit A11 can stably assemble the upper anti-rope wheel 12 and the lower anti-rope wheel 13 onto the mounting beam 5, and adjust the assembly height of the upper anti-rope wheel 12 and the lower anti-rope wheel 13, as well as the angle between the axis of the upper anti-rope wheel 12 and the lower anti-rope wheel 13 and the plane where the inner cable 61 is located, so that the upper anti-rope wheel 12 and the lower anti-rope wheel 13 work together to support and guide the inner cable 61. The rims of the upper anti-rope wheel 12 and the lower anti-rope wheel 13 apply a reaction force to the inner cable 61 to prevent the inner cable 61 from falling off.

[0046] It should also be noted that the upper anti-rope pulley 12 and the lower anti-rope pulley 13 are staggered along the length of the inner cable 61 to prevent the fixed grip 4 from passing through the single upper anti-rope pulley 12 and the lower anti-rope pulley 13 alone under the drive of the inner cable 61, so that the fixed grip 4 can pass smoothly.

[0047] To ensure that the assembly unit A11 can stably assemble the upper anti-rope wheel 12 and the lower anti-rope wheel 13 onto the mounting beam 5, and to effectively adjust the assembly height and angle of the upper anti-rope wheel 12 and the lower anti-rope wheel 13, the following technical solution is provided.

[0048] Assembly unit A11 includes hanger A111, auxiliary hanger 112, upper beam 113, lower beam 114, and steering head 115. Hanger A111 is fixedly mounted on mounting beam 5. Auxiliary hanger 112 is mounted on hanger A111 and can be vertically adjusted relative to hanger A111. Upper beam 113 and lower beam 114 are both mounted on auxiliary hanger 112. Steering heads 115 are mounted at both ends of upper beam 113 and lower beam 114. Steering heads 115 can be rotated relative to upper beam 113 and lower beam 114. Upper anti-rope pulley 12 is mounted on steering head 115 located on upper beam 113, and lower anti-rope pulley 13 is mounted on steering head 115 located on lower beam 114.

[0049] The top of the hanger A111 is fitted with a top plate, which is fixed to the installation beam 5 by a U-shaped clamp with a threaded groove at the end and a positioning nut. During on-site construction, the U-shaped clamp is upside down onto the installation beam 5 and passes through the top plate. The positioning nut is screwed onto the threaded groove and abuts against the lower surface of the top plate to achieve stable installation of the hanger A111 on the installation beam 5.

[0050] Multiple assembly through holes are provided on the hanger A111 along the height direction. Bolt assemblies pass through the auxiliary hanger 112 and the assembly through holes at specific height positions to achieve stable installation of the auxiliary hanger 112 at a specific height of the hanger A111, thereby enabling the height adjustment of the auxiliary hanger 112 and adjusting the assembly height of the upper beam 113 and the lower beam 114. The overall height of the upper anti-rope wheel 12 and the lower anti-rope wheel 13 can be adjusted to match the height of the traction wire rope.

[0051] The upper beam 113 and the lower beam 114 are both assembled to the auxiliary hanger 112 at their center via pins with threaded grooves. The pins are positioned by matching nuts. Both the upper beam 113 and the lower beam 114 can rotate around the corresponding pins on the auxiliary hanger 112. When the inner cable 61 fluctuates during operation, the upper anti-rope wheel 12 and the lower anti-rope wheel 13 can always keep in contact with the inner cable 61.

[0052] Specifically, when the fixed grip 4 moves with the inner cable 61 to the upstream end of a certain inner wheel assembly 1, the inner cable 61 at the upstream end sinks, which in turn causes the lower anti-rope pulley 13 at the upstream end to sink synchronously. Meanwhile, the lower anti-rope pulley 13 and the inner cable 61 at the upstream end tilt upwards. The tilted inner cable 61 comes into contact with the upper anti-rope pulley 12 at the downstream end and causes it to tilt upwards as well. At this time, the upper anti-rope pulley 12 at the upstream end sinks synchronously and remains in contact with the inner cable 61 at the upstream end. This design ensures that the fixed grip 4 causes the inner cable 61 to undulate when passing through the inner wheel assembly 1, thereby keeping the undulating inner cable 61 in contact with the upper anti-rope pulley 12 and the lower anti-rope pulley 13.

[0053] The steering head 115 and the corresponding upper beam 113 and lower beam 114 are provided with circumferentially evenly arranged locking teeth on their end faces. The tooth grooves on the steering head 115 are matched and engaged with the locking teeth on the corresponding upper beam 113 or lower beam 114. After the steering head 115 rotates to the set deflection angle, the steering head 115 is fixed to the end of the upper beam 113 or lower beam 114 by axially assembled bolts to ensure that the locking teeth on the two parts are nested, locked and positioned, and finally the deflection angle of the upper anti-rope wheel 12 and the lower anti-rope wheel 13 is effectively adjusted, thereby adjusting the turning angle and force value that a single set of inner wheel assembly 1 can withstand.

[0054] To ensure that the upper anti-rope pulley 12 arranged above the inner cable 61 can effectively fit and position the inner cable 61, the following technical solution is provided.

[0055] Assembly unit A11 also includes a longitudinal adjuster A116, which is mounted to the top of auxiliary hanger 112 and is used to adjust the upper limit of the height of upper beam 113.

[0056] As a common implementation method, the auxiliary hanger 112 is provided with a strip-shaped through hole and a circular through hole at the top and bottom, respectively. The pin for assembling the lower beam 114 is assembled into the circular through hole at the bottom, so that the lower beam 114 can only rotate around the assembled pin without any lifting or lowering displacement, so that the inner cable 61 can be stably erected on the lower anti-rope pulley 13. The pin for assembling the upper two cables is assembled into the strip-shaped through hole at the top, so that the upper beam 113 can not only rotate around the assembled pin, but also be adjusted up and down under the guidance of the strip-shaped through hole.

[0057] The longitudinal adjuster A116 typically uses a positioning bolt. The positioning bolt is screwed to the top of the auxiliary hanger 112, and its end extends into the strip groove and abuts against the pin at this location. This adjusts the upper limit of the upper beam 113 during lifting and lowering. Due to the limiting effect of the longitudinal adjuster A116, the upper anti-rope pulley 12 on the upper beam 113 can be effectively attached to the inner cable 61. Example 3

[0058] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 To ensure that the outer wheel assembly 2 can be stably assembled on the mounting beam 5 and to ensure that the outer wheel assembly 2 can effectively support and position the outer cable 62 so as to achieve stable operation of the outer cable 62, the following technical solution is provided.

[0059] The outer wheel assembly 2 includes an assembly unit B21 and an outer anti-rope wheel 22 and a rope-supporting wheel 23 assembled on the assembly unit B21. The assembly unit B21 is assembled on the mounting beam 5. The assembly unit B21 is used to adjust the horizontal position of the outer anti-rope wheel 22 and the height position of the rope-supporting wheel 23. The outer anti-rope wheel 22 is arranged on the inner side of the outer cable 62, and the rope-supporting wheel 23 is arranged at the bottom of the outer cable 62.

[0060] The assembly unit B21 can stably assemble the outer anti-rope wheel 22 and the support wheel 23 onto the mounting beam 5, and adjust the assembly position of the outer anti-rope wheel 22 and the support wheel 23 so that the upper anti-rope wheel 12 and the lower anti-rope wheel 13 work together to support and guide the inner cable 61.

[0061] The axis of the outer anti-rope pulley 22 is arranged vertically, while the axis of the support pulley 23 is arranged horizontally and perpendicular to the outer cable 62 at that position. The support pulley 23 provides stable support for the outer cable 62, while the outer anti-rope pulley 22 provides lateral support for the outer cable 62 to ensure stable turning of the outer cable 62.

[0062] It should also be noted that the outer anti-rope wheel 22 and the supporting rope wheel 23 are staggered along the length of the outer cable 62 to prevent the fixed rope gripper 4 from passing through the single outer anti-rope wheel 22 and supporting rope wheel 23 alone under the drive of the outer cable 62, so that the fixed rope gripper 4 can pass smoothly.

[0063] To ensure that the assembly unit B21 can stably assemble the outer anti-rope wheel 22 and the supporting rope wheel 23 onto the mounting beam 5, and to effectively adjust the assembly position of the outer anti-rope wheel 22 and the supporting rope wheel 23 so as to effectively support the outer cable 62, the following technical solution is provided.

[0064] Assembly unit B21 includes hanger B211 and mounting bracket 212. Hanger B211 is fixedly assembled to mounting beam 5. Mounting bracket 212 is assembled to hanger B211 and arranged in the horizontal direction. External anti-rope wheels 22 are assembled at both ends of mounting bracket 212. Rope support wheels 23 are assembled at the bottom of hanger B211.

[0065] The top of the hanger B211 is also fitted with a top plate, and the hanger B211 is fixed to the mounting beam 5 by U-shaped clamps and positioning nuts passing through the top plate. The mounting bracket 212 is fixed to the hanger B211 by at least two sets of bolt assemblies passing through the hanger B211, thereby ensuring that the outer anti-rope pulley 22 can be stably installed at both ends.

[0066] A set of sheave pulleys 23 is typically provided and arranged at the bottom between two sets of outer anti-rope pulleys 22 to provide stable support for the outer cable 62.

[0067] To effectively adjust the horizontal position of the outer anti-rope wheel 22 and the height position of the support wheel 23, so as to ensure that the outer anti-rope wheel 22 and the support wheel 23 can effectively fit and position the outer cable 62, the following technical solution is provided.

[0068] Assembly unit B21 also includes a lateral adjuster 213 and a longitudinal adjuster B214. The lateral adjuster 213 is assembled to both ends of the mounting bracket 212 and is used to adjust the horizontal position of the outer anti-rope wheel 22. The longitudinal adjuster B214 is assembled to the bottom of the hanger and is used to adjust the height position of the support rope wheel 23.

[0069] The lateral adjuster 213, like the longitudinal adjuster B214, uses positioning bolts. At both ends of the mounting bracket 212, there are strip-shaped through holes arranged horizontally and perpendicular to the outer cable 62. The outer anti-rope wheel 22 is assembled into the strip-shaped through hole. The lateral adjuster 213 is screwed into the mounting bracket 212 and extends into the strip-shaped through hole to abut against the rotating shaft of the outer anti-rope wheel 22. The lateral adjuster 213 is arranged inside the outer cable 62 and applies outward support to the outer anti-rope wheel 22, so that the outer anti-rope wheel 22 can effectively fit and support the outer cable 62 under the combined action of the outer cable 62 and the lateral adjuster 213. The position of the outer anti-rope wheel 22 can be adjusted by the lateral adjuster 213, which can compensate for the effects of installation errors and wheel liner wear.

[0070] A vertically oriented strip-shaped through hole is provided at the bottom of the hanger B211. The rope sheave 23 is assembled into the strip-shaped through hole. The longitudinal adjuster B214 is screwed to the bottom end of the hanger B211 and extends into the strip-shaped through hole to maintain contact with the shaft of the rope sheave 23, so as to provide upward support for the rope sheave 23. The height of the rope sheave 23 can be adjusted by the longitudinal adjuster B214 to ensure good contact between the rope sheave and the wire rope.

[0071] As an optimized implementation scheme, a circular through slot can be opened on the top plate on which the hangers A111 and B211 are mounted. The hangers A111 and B211 are rotatably installed into the circular through slots of the corresponding top plates. During on-site installation, the hangers A111 and B211 can be rotated to adjust the installation direction, which can make the outer cable 62 and the inner cable 61 form a smooth arc at the turning point, thereby reducing the running resistance. Example 4

[0072] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 To ensure that the anti-detachment rope protection component 3 can be stably assembled on the mounting beam 5, thereby providing anti-detachment protection for the inner cable 61 and providing a rapid warning when the inner cable 61 falls off, the following technical solution is provided.

[0073] The anti-rope detachment protection component 3 includes a fixed bracket 31, a lifting bracket 32, a protective wheel 33, a limiter 34, and a protection sensor 35. The fixed bracket 31 is mounted on the mounting beam 5. The lifting bracket 32 ​​is mounted on the fixed bracket 31 and can be vertically adjusted relative to the fixed bracket 31. The protective wheel 33 is rotatably mounted on the bottom end of the lifting bracket 32. The limiter 34 and the protection sensor 35 are both mounted on the lifting bracket 32. The limiter 34 is used to position the protective wheel, and the protection sensor 35 is used to detect whether the protective wheel 33 rotates.

[0074] The top of the fixed bracket 31 is also provided with a top plate, and the fixed bracket 31 is fixed to the installation beam 5 by U-shaped clamps and positioning nuts passing through the top plate. Multiple sets of bolt assemblies arranged horizontally are fixed on the fixed bracket 31. Multiple sets of assembly through holes are provided on the lifting bracket 32 ​​along the height. By inserting the bolt assembly into the assembly through hole at a specific height for positioning, the height of the lifting bracket 32 ​​and the protective wheel 33 provided on it can be adjusted to ensure that the protective wheel 33 and the inner cable 61 are at the same height.

[0075] There is a certain gap between the protective wheel 33 and the inner cable 61. When the inner cable 61 is running normally under the support and guidance of the inner wheel assembly 1, it will not come into contact with the protective wheel 33, and the anti-derailment protection component 3 will not be triggered. However, when the inner cable 61 detaches, it will come into contact with the protective wheel 33, thereby causing the protective wheel 33 to rotate against the stopping force of the limiter 34. This change will be detected by the protection sensor 35, and the detection signal will be transmitted to the control device to issue a fault stop signal.

[0076] The top of the protective wheel 33 is provided with limiting teeth 331 arranged in a ring array. The limiter 34 is abutted against the top of the protective wheel 33 by a telescopic rod supported by a spring. The preload of the spring can be adjusted by bolts, thereby adjusting the stopping force of the limiter 34.

[0077] When the anti-detachment protection component 3 is not triggered, the telescopic rod extends downward under the push of the spring and engages between two adjacent sets of limiting teeth 331. The limiting effect of the limiting teeth 331 and the telescopic rod prevents the protective wheel 33 from rotating ineffectively when not triggered, thus preventing false alarms. When the inner cable 61 detaches and causes the protective wheel 33 to tend to rotate, the limiting teeth 331 rotate accordingly, and under the action of their inclined surfaces, drive the telescopic rod to overcome the spring resistance and push upward, thereby causing the protective wheel 33 to rotate.

[0078] The protection sensor 35 uses a magnetic sensing component. Permanent magnets 332 are evenly arranged in a ring array at the top of the protection wheel 33. When the permanent magnets 332 rotate with the protection wheel 33 and approach the magnetic sensing component, a change in magnetic field strength will be detected, which will determine that the inner cable 61 has derailed. Example 5

[0079] Please see Figure 2 To ensure that the inner cable 61 and the outer cable 62 can carry passengers, a passenger carrier 41 is installed on the fixed cable holder 4.

[0080] The bottom of the passenger vehicle 41 is equipped with a hanging chair or a hanging box, in which personnel can sit securely and move stably by the fixed grip 4 and the passenger vehicle 41 through the running cable, so as to realize the function of passenger transfer.
