Description

Technical Field

[0001] This utility model relates to the field of safety technology for freight cableways, and in particular to a freight car blocking system for a dual-line circulating freight cableway that prevents the failure of the detached hook-up, which is suitable for emergency braking of sliding freight cars between the cargo box exit-side hook-up device and the station entrance support. Background Technology

[0002] The dual-line circulating freight cableway switches between low-speed operation within the station and high-speed operation along the line by disengaging the coupling device. However, when the coupling device fails, uncoupled freight cars may slip off the support saddle at the station entrance, break free of the load-bearing rope, and fall, causing a serious accident. The existing technology has the following drawbacks:

[0003] The concave roller energy conversion scheme requires a long rigid rail side when leaving the station, which significantly increases the length of the station building and makes it impossible to implement in some terrain conditions. Rainy, snowy, or oily weather can reduce the friction coefficient of the track rope, and the kinetic energy of unattached freight cars cannot be fully consumed. They may overturn over the support saddle at the station entrance, slide onto the track, break through the support rope, and fall onto the track, causing an accident. It heavily relies on extending the station building and slowing down when climbing slopes, has poor terrain adaptability, and still has the risk of sliding when the friction coefficient is reduced in rainy or snowy weather.

[0004] The convex roller status monitoring scheme: When a freight car leaves the station using its convex vertical roller assembly, a monitoring device is installed to prevent the freight car from sliding onto the track. If a secure attachment is found, measures such as not departing, slowing down, or stopping are taken, significantly reducing the escalation of the accident. However, this scheme cannot prevent the freight car from overturning the station gate support saddle, sliding onto the track, breaking the support rope, and falling onto the track, damaging equipment or even injuring personnel, thus causing an accident. It can only control the scale of the accident by stopping the vehicle; it cannot intercept an out-of-control freight car that has already skidded away.

[0005] Therefore, there is an urgent need for an active braking device that can quickly respond and safely brake trucks when the harness fails. Utility Model Content

[0014] The controller is connected in communication with the cable clamping status monitoring switch and the locking pin release mechanism;

[0015] When the cable clamp status monitoring switch detects that the truck's cable clamp is not properly engaged and has slid off the clamp onto the track, it transmits a signal to the controller.

[0042] First Embodiment

[0043] Please see Figure 1-3This embodiment provides a double-line circulating freight cableway detachment and anchorage failure prevention system, including a cable grip anchorage status monitoring switch 1, a controller 2, and an arresting device 3. The cable grip anchorage status monitoring switch 1 acquires the usage status of the anchorage device. When the cable grip anchorage status monitoring switch 1 detects that the freight car 4 is not properly anchored and has slid off the anchorage device onto the line, it transmits a signal to the controller 2. The controller 2 controls the arresting device 3 to release the locking pin release mechanism via an electromagnet, thus unfolding the mechanical arresting net mechanism to intercept the freight car 4. This arresting system has a small overall footprint, is suitable for cableway use in various terrain environments, responds quickly, and has reliable interception action, providing a guarantee for the freight car 4's convex vertical roller assembly to leave the station.

[0044] The cable gripper anchor status monitoring switch 1 is used to acquire the usage status of the anchoring device. In this embodiment, to improve the redundancy of the detection and triggering system, the cable gripper anchor status monitoring switch 1 also includes an infrared sensor, a pressure sensor, or a visual recognition system for acquiring the usage status of the anchoring device. Multi-sensor fusion detection is adopted, adding one or more of the infrared sensor, pressure sensor, or visual recognition system to the existing cable gripper status detection switch to avoid misjudgments or missed judgments due to the failure of a single detection point.

[0045] The barrier device 3 is located between the hanging device and the station support, and includes a support 31, a locking pin release mechanism located on the upper part of the support 31, and a mechanical barrier net mechanism that spans the support 31 and is connected to the locking pin release mechanism.

[0046] The bracket 31 is a cylindrical structure located on both sides of the truck 4. The bracket 31 is hollow inside and is equipped with guide wheels 32 on the top.

[0047] The locking pin release mechanism is located on the upper part of the bracket 31, below the guide wheel 32. Driven by an electromagnet 33, the mechanism includes the electromagnet 33 and a locking pin 34 that can be attracted and locked by the electromagnet 33. The controller 2 communicates with the cable attachment status monitoring switch 1 and the locking pin 34 release mechanism. The controller 2 controls the operating state of the electromagnet 33. When the electromagnet 33 is energized, the locking pin 34 is attracted by the electromagnet 33, and the mechanical barrier net mechanism is in a relaxed state, concealing the barrier net under the truck 4. When the electromagnet 33 is de-energized, the locking pin 34 is released, the counterweight 35 falls, and the barrier net 36 stretches and blocks the truck 4 in front of its path. The barrier net 36, through elastic deformation, delays the impact time, allowing the truck 4 to slowly stop and prevent it from sliding onto the track, thus avoiding an accident. The specific structure of the electromagnet 33 and the locking pin 34 is not limited; the electromagnet 33 can be fixed to the bracket 31, and the locking pin 34 can be mounted on the counterweight 35 or the barrier rope.

[0048] The mechanical barrier net mechanism has leads at both ends that pass through guide wheels 32 and are connected to the locking pin 34 release mechanism. Specifically, the mechanical barrier net mechanism includes a barrier net 36, a counterweight 35, and a counterweight locking component.

[0049] The top two ends of the barrier net 36 are connected to barrier ropes 37, which can be fixed or quick-release, such as by hooks or buckles, to facilitate quick replacement of damaged barrier nets. The other end of the barrier rope 37 passes through the guide wheel 32 and the locking pin 34 release mechanism and enters the inner cavity of the bracket 31, where the counterweight 35 is located.

[0050] In this embodiment, a reverse lock 38 is provided at the bottom of the inner cavity of the bracket 31 as a locking element for the counterweight. It can participate in a spring mechanism or magnetic locking to lock the counterweight 35. The structure of the reverse lock 38 in this embodiment is not limited; for example:

[0051] It can be attached Figure 1 A spring mechanism is installed inside the cylindrical inverted lock 38. When the weight 35 falls, the spring is compressed, resulting in a quick locking action. Correspondingly, a locking groove matching the shape of the inverted lock 38 is also provided inside the bottom center of the weight 35. This method ensures that the inverted lock 38 is quickly secured when the weight 35 falls.

[0052] Alternatively, strong magnets can be installed on the inverted lock 38 and the counterweight 35 respectively, or the inverted lock can use a powerful electromagnet, and the counterweight can be made of a material that can be attracted by magnets. When the counterweight 35 falls, the magnetic force will quickly fix the inverted lock 38. This method can provide a fast and reliable locking effect and quick reset.

[0053] In order to regulate the falling path of the hammer 35, this embodiment also provides a guide groove inside the bracket 31 and a guide post 351 on the hammer, so that the hammer falls vertically without deviating.

[0054] A buffer pad 39 is also provided at the bottom of the inner cavity of the support 31 to reduce the impact of the counterweight 35. The entire blocking process adopts a double buffer structure, with the buffer pad 39 and the blocking net 36 elastically deforming at the end of the counterweight 35's stroke to reduce the impact on the cargo box and cableway structure.

[0055] Furthermore, the upper part of the barrier net 36 is a collapsible metal mesh, and the lower part is an elastic barrier net 36. The collapsible metal mesh is coated with an anti-corrosion material on the outside, while the elastic barrier net 36 has an outer layer of highly elastic material and an inner layer of highly tough material. Specifically, the collapsible metal mesh adopts an aluminum alloy honeycomb structure, with an outer layer coated with a polyurethane anti-corrosion coating. The elastic barrier net has an outer layer of silicone rubber (elastic deformation rate ≥40%) and an inner layer of aramid fiber woven mesh (tensile strength ≥500MPa).

[0056] The triggering procedure for the detachment failure arresting system of the dual-line circulating freight cableway is as follows:

[0057] The cable clamp status detection switch sends a knot failure signal to controller 2;

[0058] Controller 2 controls electromagnet 33 to release locking pin 34 when de-energized;

[0059] The hammer 35 falls freely, and the barrier rope is pulled by the guide wheel 32 to raise the barrier net.

[0060] The hammer 35 falls to the bottom and locks with the inverted lock 38;

[0061] The barrier net intercepts four trucks and applies elastic braking.

[0062] Second Embodiment

[0063] Please refer to Figure 3 This embodiment provides a double-line circulating freight cableway detachment failure prevention system, which is largely the same as the double-line circulating freight cableway detachment failure prevention system in the first embodiment. The difference is that the prevention system in this embodiment also has an electric heating element 301 installed in the guide wheel 32 and the locking pin 34 release mechanism. The electric heating element 301 is communicatively connected to the controller 2, and the controller 2 controls the usage status of the electric heating element 301. The temperature and humidity sensor can be installed at any suitable position on the prevention device 3.

[0064] For freight cableways, which are often located in mountainous areas, the guide wheel 32 and locking pin 34 mechanism are coated with a hydrophobic coating. The built-in electric heating element 301 is automatically started and stopped by the controller 2 according to the temperature and humidity sensor signal to prevent the mechanism from jamming due to rain, snow and ice.

[0065] The arresting system is powered by a dual power supply 302, which includes a main power supply and a supercapacitor, ensuring that an arresting action can still be completed in the event of a power outage.

[0066] To enhance the system's self-testing and early warning functions, this system also has a power-on self-testing mechanism. When device 3 starts up, it automatically detects the status of electromagnets, sensors, and barrier nets, and triggers audible and visual alarms when a fault occurs.

[0067] Its usage is as follows:

[0068] Standby state: The barrier net 36 is hidden below the passage of the truck 4, and the counterweight 35 is locked in the high position of the inner cavity of the bracket 31 by the locking pin 34. If the temperature is at a low threshold, the controller 2 controls the electric heating element to maintain the guide wheel 32 and the locking pin 34 mechanism in an anti-freezing state.

[0069] Triggered state:

[0070] When the multi-sensor detects that the truck 4 is not hooked and has slipped off the hooking device, the controller 2 sends a signal to the electromagnet 33 to release the locking pin 34.

[0071] The hammer 35 falls freely and is pulled up by the barrier rope 37 to raise the barrier net 36.

[0072] When the hammer 35 falls to the bottom of the inner cavity of the bracket 31, the position is locked by the inverted lock 38, and the barrier net is fully deployed;

[0073] When the out-of-control truck 4 collides with the barrier net, the collapsible metal mesh absorbs the impact energy through plastic deformation, while the elastic barrier net slows down the braking process through layered deformation.
