Description

Technical Field

[0001] This utility model relates to the field of cableway safety detection technology, and in particular to a safety detection device for cableway detachment systems. Background Technology

[0002] A cableway is a transportation system that uses overhead steel cables as the main support and traction means. It is widely used in passenger transport, freight transport, and material transport in specific scenarios. The cableway detachment system is a key subsystem in modern passenger cableways. It is mainly used to realize the automatic connection and separation between the car and the traction steel cable, thereby improving the operating efficiency and safety of the cableway. The safety detection device of the cableway detachment system is a key component to ensure the safe operation of the cableway. It is designed to monitor the operating status of the detachment system in real time and promptly detect and deal with potential safety hazards.

[0003] There are still some problems with the safety detection devices of existing cableway detachment systems. Among them, U-shaped needles, as the main mechanical signal switches, are widely used in modern cableways. However, due to installation limitations, they are mostly installed in outdoor environments. Although the U-shaped needles themselves are treated with anti-corrosion measures, in some coastal and high-humidity areas, the internal corrosion of the U-shaped needles is relatively fast, which affects signal transmission and poses safety hazards. Therefore, those skilled in the art have provided a safety detection device for cableway detachment systems to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety detection device for cableway detachment systems. The device integrates components such as the break needle and switch body through injection molding, improving waterproof and corrosion-resistant properties. The lower part uses a waterproof connector for a firm and reliable connection, eliminating the need for intermediate wiring. This results in more stable and reliable performance, effectively extending service life and reducing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety detection device for a cableway detachment system, comprising a switch body, a broken needle fixedly connected to the center of the lower end face of the switch body, a waterproof connector provided at the upper end of the switch body, a threaded column fixedly connected to the edge of the upper end face of the switch body, a threaded sleeve fixedly connected to the lower end face of the waterproof connector outside the threaded column, a first sealing component provided between the lower end face of the threaded sleeve and the upper end face of the switch body, and a second sealing component provided on the inner side wall of the threaded sleeve near the upper part of the outer side wall of the threaded column;

[0006] The first sealing assembly includes a first groove, which is formed on the upper end face of the switch body. A first permanent magnet ring is fixedly connected to the center of the lower inner wall of the first groove. A first sealing gasket is sleeved on the upper part of the outer side wall of the first permanent magnet ring. The first sealing gasket is fixedly connected inside the first groove. A second groove is formed on the lower end face of the upper threaded sleeve of the first sealing gasket. A second permanent magnet ring is fixedly connected to the center of the upper inner wall of the second groove. A second sealing gasket is sleeved on the lower part of the outer side wall of the second permanent magnet ring. The second sealing gasket is fixedly connected inside the second groove.

[0007] The above technical solution utilizes the mutual magnetic attraction between the first and second permanent magnet rings to increase the pre-tightening force between the first and second sealing gaskets, thereby improving the sealing performance and preventing moisture from entering.

[0008] Furthermore, the switch body and the breaking needle are integrally molded by injection molding;

[0009] The above technical solution integrates components such as the break pin and switch body into a single injection mold, improving waterproof and corrosion-resistant properties. The lower part uses a waterproof connector, ensuring a firm and reliable connection. This eliminates the need for intermediate wiring, resulting in more stable and reliable performance, effectively extending service life and reducing maintenance costs.

[0010] Furthermore, the second sealing assembly includes a third groove, which is formed on the upper part of the inner sidewall of the threaded sleeve. A third sealing gasket is fixedly connected inside the third groove. A trapezoidal groove is formed at the center of the inner sidewall of the third sealing gasket, and a tightening ring is provided inside the trapezoidal groove.

[0011] Through the above technical solution, when the tightening ring comes into contact with water, it expands. The trapezoidal design causes the upper and lower ends to squeeze the third sealing gasket, which is then pressed against the outside of the threaded column, thus achieving a resealing effect when water vapor seeps in.

[0012] Furthermore, the trapezoidal groove on the inner side of the tightening ring is provided with absorbent cotton;

[0013] The above technical solution uses absorbent cotton to adsorb incoming water vapor.

[0014] Furthermore, the tightening ring is made of cross-linked water-swellable rubber;

[0015] The above technical solution allows the tightening ring to expand upon contact with water, thus resealing the seal.

[0016] Furthermore, the first permanent magnet ring and the second permanent magnet ring are magnetically attracted to each other;

[0017] The above technical solution increases the pre-tightening force between the first and second sealing gaskets by the mutual magnetic attraction between the first and second permanent magnet rings, thereby improving the sealing performance.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the safety detection device for the cableway detachment system integrates components such as the break needle and switch body into a single injection molded part, improving the waterproof and corrosion-resistant effect. The lower part adopts a waterproof connector, which is firmly and reliably connected, eliminating the intermediate wiring part, making the performance more stable and reliable, effectively extending the service life and reducing the maintenance cost. Through the mutual magnetic attraction between the first permanent magnet ring and the second permanent magnet ring, the pre-tightening force between the first sealing gasket and the second sealing gasket is increased, increasing the sealing performance and thus improving the sealing effect to prevent water vapor from entering.

[0020] 2. In this utility model, if water vapor enters between the threaded post and the threaded sleeve, the water vapor is absorbed by the absorbent cotton. When the tightening ring comes into contact with the absorbent cotton, it expands. The trapezoidal design causes the upper and lower ends to squeeze the third sealing gasket, which is then pressed against the outside of the threaded post. This allows for a second sealing effect when water vapor seeps in, improving the safety of use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 An embodiment of this utility model provides a safety detection device for a cableway detachment system, comprising a switch body 1, a broken needle 2 fixedly connected to the center of the lower end face of the switch body 1, a waterproof connector 3 provided at the upper end of the switch body 1, a threaded post 4 fixedly connected to the edge of the upper end face of the switch body 1, a threaded sleeve 5 fixedly connected to the lower end face of the waterproof connector 3 outside the threaded post 4, a first sealing component 6 provided between the lower end face of the threaded sleeve 5 and the upper end face of the switch body 1, and a second sealing component 7 provided on the inner side wall of the threaded sleeve 5 near the upper part of the outer side wall of the threaded post 4.

[0031] like Figure 3 As shown, the first sealing assembly 6 includes a first groove 601, which is formed on the upper end face of the switch body 1. A first permanent magnet ring 602 is fixedly connected to the center of the lower inner wall of the first groove 601. A first sealing gasket 603 is sleeved on the upper part of the outer wall of the first permanent magnet ring 602. The first sealing gasket 603 is fixedly connected inside the first groove 601. A second groove 604 is formed on the lower end face of the threaded sleeve 5 at the upper end of the first sealing gasket 603. A second permanent magnet ring 605 is fixedly connected to the center of the upper inner wall of the second groove 604. A second sealing gasket 606 is sleeved on the lower part of the outer wall of the second permanent magnet ring 605. The second sealing gasket 606 is fixedly connected inside the second groove 604. Through the mutual magnetic attraction between the first permanent magnet ring 602 and the second permanent magnet ring 605, the pre-tightening force between the first sealing gasket 603 and the second sealing gasket 606 is increased, thereby increasing the sealing performance and preventing moisture from entering.

[0032] The switch body 1 and the breaking needle 2 are integrally injection molded, which improves the waterproof and corrosion-resistant effect. The lower part adopts a waterproof connector 3, which is firmly and reliably connected. It eliminates the intermediate wiring part, making the performance more stable and reliable, effectively extending the service life and reducing the maintenance cost.

[0033] like Figure 4As shown, the second sealing component 7 includes a third groove 701, which is located on the upper part of the inner wall of the threaded sleeve 5. A third sealing gasket 702 is fixedly connected inside the third groove 701. A trapezoidal groove 703 is provided at the center of the inner side wall of the third sealing gasket 702. A tightening ring 705 is provided inside the trapezoidal groove 703. When the tightening ring 705 comes into contact with water, it expands. The trapezoidal design causes the upper and lower ends to squeeze the third sealing gasket 702, so that the third sealing gasket 702 is squeezed on the outside of the threaded post 4, thereby achieving a re-sealing effect when water vapor seeps in.

[0034] The trapezoidal groove 703 inside the tightening ring 705 is provided with water-absorbing cotton 704, which absorbs the incoming water vapor.

[0035] The tightening ring 705 is made of cross-linked water-swellable rubber. When the tightening ring 705 comes into contact with water, it expands and re-seals.

[0036] The first permanent magnet ring 602 and the second permanent magnet ring 605 are magnetically attracted to each other. Through the mutual magnetic attraction between the first permanent magnet ring 602 and the second permanent magnet ring 605, the pre-tightening force between the first sealing gasket 603 and the second sealing gasket 606 is increased, thereby increasing the sealing performance.

[0037] Working principle: The breaking needle 2 is a U-shaped needle installed on the equipment to monitor abnormal deformation and displacement of the equipment. The breaking needle 2 is made of special materials and is connected to the operation control console as part of the signal line. When a certain part of the monitored equipment is damaged, deformed or displaced locally, the breaking needle 2 will break when it is squeezed by external force to a certain extent. The circuit break signal is transmitted to the control console, which will issue an alarm and stop the main unit. Maintenance personnel can check the equipment according to the position signal to avoid safety accidents. This is a commonly used technical means in the existing technology and will not be described in detail here.

[0038] During installation, the threaded sleeve 5 is fitted onto the threaded post 4, and the first sealing gasket 603 and the second sealing gasket 606 are in contact with each other. The first permanent magnet ring 602 and the second permanent magnet ring 605 are magnetically attracted to each other, which increases the pre-tightening force between the first sealing gasket 603 and the second sealing gasket 606, increases the sealing performance, and thus improves the sealing effect and prevents water vapor from entering.

[0039] If moisture enters between the threaded post 4 and the threaded sleeve 5, the water-absorbing cotton 704 absorbs the moisture, and the tightening ring 705 comes into contact with the water-absorbing cotton 704. When the tightening ring 705 comes into contact with water, it expands. The trapezoidal design causes the upper and lower ends to squeeze the third sealing gasket 702, so that the third sealing gasket 702 is squeezed on the outside of the threaded post 4, thereby achieving a re-sealing effect when moisture seeps in, improving the safety of use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
