[0002] A needle-type switch device for real-time detection of cableway wire rope detachment, a cableway detachment detection device. During cableway operation, wire rope detachment directly threatens the safety of equipment and personnel; existing detachment detection products have the following key defects:

[0003] 1. Poor waterproofing: The needle insertion point, needle locking point, wire connection end, and other parts of the detection switch are not properly sealed. Under humid and dusty outdoor conditions, water and dust can easily enter and accumulate, leading to short circuits or poor contact, resulting in a high rate of false alarms and missed alarms.

[0004] 2. Inaccurate installation and positioning: Due to the lack of a reliable installation and positioning structure, the wire rope cannot accurately strike the detection needle when it comes off, resulting in low detection reliability;

[0005] 3. Unreliable electrical connection: The connection between the wire and the detection probe is prone to loosening under long-term vibration, leading to signal transmission interruption;

[0006] 4. Low production efficiency: The original switch body was made by splitting and assembling bar stock on a metal cutting machine, which was cumbersome, time-consuming and difficult to scale up. Summary of the Invention

[0007] To address the aforementioned technical issues, this utility model provides a novel cableway derailment detection device that achieves precise detection by triggering a broken needle upon derailment and immediately triggering an alarm. It is also adaptable to complex outdoor working conditions and large-scale production needs, and is suitable for safety protection systems of passenger and freight cableways. It can accurately trigger derailment alarms and ensure long-term stable operation.

[0008] This utility model is achieved through the following technical solution:

[0009] A cableway derailment detection device includes a housing, with a U-shaped break needle mounted at one end and a waterproof connector mounted at the other end. An inner core is installed inside the housing, with an installation hole for mounting a metal insert. A retaining ring is installed between the inner core and the waterproof connector. A quick-connect waterproof power plug cable is installed at one end of the waterproof connector. Four sets of waterproof sealing rings are also installed inside the housing, respectively positioned between the U-shaped break needle and the housing, between the U-shaped break needle and the inner core, between the housing and the waterproof connector, and between the waterproof connector and the quick-connect waterproof power plug cable.

[0010] Preferably, the positioning pin device inside the outer shell is precisely matched with the positioning hole opened in the inner core.

[0011] Preferably, the outer shell is provided with a positioning mounting groove, which matches the mounting base slot of the cableway equipment with the mounting screw.

[0012] Preferably, the end of the inner core is provided with a positioning hole, which cooperates with the positioning pin of the outer shell to achieve accurate positioning without deviation.

[0013] Preferably, the inner core carries a metal insertion hole, and the positioning structure ensures the alignment accuracy between the metal insertion hole and the U-shaped broken needle body.

[0014] Preferably, a metal crown spring is integrated inside the metal socket, and the metal crown spring is an elastic copper sheet.

[0015] Preferably, the waterproof connector has a comb-like tooth structure at its tail end.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By incorporating four sets of waterproof sealing rings and waterproof joints, IP-level waterproofing is achieved, completely resolving the issues of "water ingress failure, false alarms, and missed alarms" in existing products.

[0018] The triple positioning system, consisting of the locating pins on the outer shell, the locating holes in the inner core, and the mounting groove on the outer shell, ensures the installation accuracy during device assembly and actual use.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. As shown in Figures 1 and 2, a cableway derailment detection device includes a housing 2. A U-shaped breaking needle 1 is installed at one end of the housing 2, and a waterproof connector 5 is installed at the other end. An inner core 3 is installed inside the housing 2, and an installation hole is provided in the inner core 3 for installing a metal insertion hole 4. A retaining ring 6 is installed between the inner core 3 and the waterproof connector 5. A quick-connect waterproof power plug cable wire 8 is installed at one end of the waterproof connector 5. A waterproof sealing ring 7 is also installed inside the housing 2. Four sets of waterproof sealing rings 7 are provided, and the four sets of waterproof sealing rings 7 are respectively located between the U-shaped breaking needle 1 and the housing 2, between the U-shaped breaking needle 1 and the inner core 3, between the housing 2 and the waterproof connector 5, and between the waterproof connector 5 and the quick-connect waterproof power plug cable wire 8.

[0034] In this implementation scheme, specifically, the U-shaped breaking needle body 1 is made of a special brittle alloy conductive material, which does not undergo plastic deformation and breaks directly upon impact, ensuring the reliability of the detection logic; the U-shaped breaking needle body 1 is set with a U-shaped structure to ensure continuous transmission of electrical signals during normal cableway operation, adapts to the impact trajectory of the cableway wire rope after detachment, and ensures triggering reliability; the U-shaped breaking needle body 1 remains intact and the circuit is conductive under normal conditions; when detached from the cableway, it breaks upon impact with the wire rope, cutting off the circuit and triggering an alarm.

[0035] In this embodiment, specifically, the outer shell 2 is integrally injection molded from an insulating material with excellent weather resistance.

[0036] In this implementation plan, in conjunction with the appendix Figure 3As shown, the positioning pin device in the inner cavity of the outer shell 2 precisely matches the positioning hole opened in the inner core 3 to ensure that the inner core 3 is installed without deviation.

[0037] In this embodiment, specifically, the outer shell 2 is provided with a positioning mounting groove, which matches the mounting base slot of the cableway equipment with the mounting screw, so as to realize the overall quick positioning of the switch.

[0038] In this embodiment, specifically, the outer shell 2 provides mechanical support for the internal components, ensuring that the U-shaped breaking needle body 1 is reliably installed and connected to the mounting base.

[0039] In this implementation plan, in conjunction with the appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the inner core 3 is integrally injection molded from a weather-resistant insulating material.

[0040] The inner core 3 is provided with a positioning hole at its end, which cooperates with the positioning pin of the outer shell 2 to achieve accurate positioning without deviation.

[0041] The inner core 3 carries the metal socket 4, and the positioning structure ensures the alignment accuracy between the metal socket 4 and the U-shaped broken needle body 1, thus ensuring the stability of the electrical connection.

[0042] In this implementation plan, in conjunction with the appendix Figure 8 As shown, a metal crown spring is integrated inside the metal socket 4. The metal crown spring is an elastic copper sheet with multiple contact points, providing stable and reliable contact performance. It makes elastic contact with the insertion end of the U-shaped broken needle body 1, ensuring reliable connection and offsetting the effects of vibration and temperature deformation.

[0043] In this embodiment, specifically, the metal socket 4 uses a silver-plated brass alloy substrate to reduce contact resistance and improve conductivity and corrosion resistance. In this embodiment, specifically, the quick-connect waterproof power plug cable conductor 8 is crimped to the metal socket 4 using a special crimping tool, crimping from all four sides to ensure sufficient connection tensile strength and prevent the quick-connect waterproof power plug cable conductor 8 from loosening.

[0044] In this embodiment, specifically, the metal socket 4 enables electrical connection between the U-shaped break pin 1 and the quick-connect waterproof power plug cable wire 8, and the crown spring design ensures the reliability of the connection under long-term vibration.

[0045] In this embodiment, specifically, the waterproof connector 5 has a comb-like tooth structure at its tail. When tightened, the comb-like teeth contract, squeezing the internal sealing ring to fit tightly against the quick-connect waterproof power plug cable wire 8. Waterproofing is achieved through the mechanical deformation of "comb-like tooth contraction → sealing ring radial compression → wrapping the cable".

[0046] In this embodiment, specifically, the waterproof connector 5 is used to seal the outlet end of the quick-connect waterproof power plug cable wire 8, preventing moisture from entering the switch from the wire side.

[0047] In this implementation plan, in conjunction with the appendix Figure 7 As shown, the retaining ring 6 is a circular retaining ring made of plastic, with two circular holes in the middle. The two circular holes are used to pass through the metal socket 4 and connect to the wire.

[0048] In this implementation scheme, specifically, when the waterproof connector 5 is tightened, the retaining ring 6 abuts against the tail of the metal socket 4, restricting the axial movement of the metal socket 4 and ensuring long-term stable electrical connection.

[0049] In this embodiment, specifically, the waterproof sealing ring 7 is made of fluororubber, which is resistant to temperatures from -20℃ to 200℃, and is oil-resistant and aging-resistant.

[0050] In this implementation plan, specifically, by setting multiple sets of waterproof sealing rings 7, that is, by setting multiple sealing barriers, moisture and dust are completely blocked from entering the switch, making it suitable for outdoor humid and dusty working conditions.

[0051] In this implementation plan, specifically, the quick-connect waterproof power plug cable conductor 8 is integrally injection molded, waterproof and flame retardant, and can be quickly replaced when needed.

[0052] In this implementation scheme, specifically, under normal conditions, the U-shaped breaking needle 1 remains intact, the metal socket 4 is in elastic and tight contact with the U-shaped breaking needle 1, the circuit signal is continuously conducted, and the control system determines that "the cableway has not detached"; when detachment is triggered: after the wire rope detaches, it impacts the U-shaped breaking needle 1, the brittle needle breaks instantly, and the circuit / signal path is forcibly interrupted; during safety response, the external control system (such as PLC, safety controller) detects the signal interruption and immediately triggers safety measures such as audible and visual alarms and cableway shutdown.

[0053] In this implementation plan, specifically, in performance testing, adaptive adjustments can be made for ultra-low temperature (-50℃) or highly corrosive (marine environment) scenarios. For example, the material of the waterproof sealing ring 7 can be replaced with a highly corrosive material that can withstand temperatures from -50℃ to 300℃; the material of the outer shell 2 can be replaced with a plastic material that can withstand temperatures from -60℃ to 260℃ and is resistant to chemical corrosion; and the plating of the metal socket 4 can be replaced with gold plating to improve corrosion resistance and make it suitable for high-salt-fog marine environments.

[0054] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
