Description

Technical Field

[0001] This utility model relates to the field of traveling cable technology, and in particular to a traveling cable with a guiding structure. Background Technology

[0002] Traveling cables are multi-functional cables specifically designed for use in elevator systems. They are responsible for transmitting power from a fixed power source to the moving elevator car and related equipment, ensuring the normal operation of the elevator's motor, lighting, ventilation, air conditioning, and other electrical equipment. They are mainly used in various types of elevator systems and are a key component for elevator operation, including home elevators, commercial elevators, hospital elevators, and other scenarios.

[0003] In existing technologies, the elevator traveling cable will swing during operation and stopping. Especially at the moment of elevator start-up and stop, the traveling cable often swings greatly due to inertia, which can easily cause the traveling cable to scrape, hook, or entangle with the traction steel rope or elevator components in the shaft, which can easily lead to accidents.

[0004] An existing patent (publication number: CN220351422U) discloses an elevator traveling cable guiding device. The traveling cable passes through rollers, and as the elevator moves, it also drives the rollers and counterweights to move up and down along the guide rail. The traveling cable remains taut under the weight of the counterweights, providing tension and limiting its range of motion. This ensures that the traveling cable does not sway during the elevator's up-and-down movement, effectively preventing it from scraping against elevator components in the shaft. The overall structure is simple and compact, easy to install, occupies little space, and is low in cost. It is particularly suitable for situations where elevator shaft components are compactly arranged and where the traveling elevator experiences significant swaying, effectively solving the problem of vibration and swaying of the traveling cable during elevator operation.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that can effectively prevent cable swaying through the cooperation of components such as rollers and counterweights, in actual use, the slider needs to engage and slide along the guide rail. After prolonged use, internal rust or excessive friction may cause jamming during the sliding process. This jamming may cause the cable body to be stretched or bent, resulting in a loose overall cable structure and reduced mechanical performance. Summary of the Invention

[0006] The purpose of this utility model is to provide a following cable with a guiding structure, which can avoid excessive friction and stiffness of the slider during sliding, which would cause jamming and result in the cable body being pulled or bent, affecting the internal structure, and maintaining the stable sliding of the cable body, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a traveling cable with a guiding structure, including a guide rail, a mounting frame slidably connected to the outside of the guide rail, a gravity block fixedly mounted on the top of the mounting frame, an abutment wheel rotatably connected inside the mounting frame, and a cable body passing through between the abutment wheel and the mounting frame, a slider fixedly mounted on one end of the gravity block that passes through the guide rail, and a lubrication mechanism provided on one side of the guide rail;

[0008] The lubrication mechanism includes an abutment block, which is fixedly installed on the top of the mounting frame. A storage box is fixedly installed on the upper part of the outer wall of the guide rail, and a conveying pipe extends from the top of the storage box. An abutment rod extends from the bottom of the storage box, and a sleeve is fitted on the end of the abutment rod outside the storage box. A push plate is fixedly installed on the end of the abutment rod inside the storage box.

[0009] Preferably, a sealing gasket is embedded at the top of the push plate, and an oil outlet is provided on one side of the inside of the storage box.

[0010] Preferably, connecting plates are fixedly installed on both sides of the outer wall of the storage box, and an abutting roller is rotatably connected between the two connecting plates.

[0011] Preferably, the sleeve has an internal mounting groove, and the mounting groove is provided with a positioning mechanism.

[0012] Preferably, the positioning mechanism includes a limiting cylinder, which is fixed to the bottom of the inner end of the placement groove, and an electromagnet is embedded in the bottom of the inner end of the limiting cylinder.

[0013] Preferably, a permanent magnet is fixedly installed at the bottom end of the abutment rod corresponding to the position of the limiting cylinder, and a spring is fixedly installed on the outside of the permanent magnet at the bottom end of the abutment rod.

[0014] Preferably, a clamping plate is fixedly installed at one end of the slider that passes through the guide rail, and an anti-collision pad is embedded at the bottom end of the gravity block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the pressure of the push plate to allow lubricating oil to pass through the oil outlet and drip into the guide rail to lubricate the slider. This achieves an automatic lubrication effect, avoiding the troublesome manual intervention. At the same time, lubrication can prevent the slider from experiencing excessive friction and stiffness during sliding, which could lead to jamming and cause the cable body to be pulled or bent, affecting the internal structure and maintaining the stable sliding of the cable body.

[0017] 2. By leveraging the elastic contraction of the spring and cooperating with the electromagnet to push the permanent magnet with the same magnetic pole, the position of the sleeve can be adjusted according to the lubrication requirements. Under normal circumstances, this avoids the contact block from contacting the sleeve, which would squeeze out the lubricating oil and cause waste. When lubrication is needed, the sleeve can contact the contact block to squeeze the lubricating oil and thus lubricate the slider. This allows for adjustment as needed, improving convenience and applicability. Attached Figure Description

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 5 A guided cable includes a guide rail 1, a mounting bracket 2 slidably connected to the outside of the guide rail 1, a gravity block 3 fixedly mounted on the top of the mounting bracket 2, an abutment wheel 4 rotatably connected inside the mounting bracket 2, a cable body 6 passing through the abutment wheel 4 and the mounting bracket 2, a slider 5 fixedly mounted on one end of the gravity block 3 that passes through the guide rail 1, and a lubrication mechanism 7 provided on one side of the guide rail 1; the lubrication mechanism 7 includes an abutment block 701 fixedly mounted on the top of the mounting bracket 2, and a storage box 70 fixedly mounted on the upper outer wall of the guide rail 1. 2. A conveying pipe 703 extends from the top of the storage box 702, and an abutment rod 704 extends from the bottom of the storage box 702. A sleeve 705 is fitted onto one end of the abutment rod 704 outside the storage box 702, and a push plate 706 is fixedly installed on the other end of the abutment rod 704 inside the storage box 702. A sealing gasket 707 is embedded at the top of the push plate 706. An oil outlet hole 708 is opened on one side of the inside of the storage box 702. Connecting plates 8 are fixedly installed on both sides of the outer wall of the storage box 702, and an abutment roller 9 is rotatably connected between the two connecting plates 8.

[0029] By adopting the above technical solution, when the mounting frame 2, gravity block 3, and abutment wheel 4 are driven by the cable body 6 and slide along the guide rail 1 via the slider 5, the tension of the cable body 6 is maintained to prevent swaying, thus providing a guiding effect. When the mounting frame 2 rises to the top, the abutment block 701 abuts against the sleeve 705, causing the abutment rod 704 to drive the push plate 706. The sealing gasket 707 squeezes the lubricating oil inside the storage box 702, and the lubricating oil drips into the guide rail 1 through the oil outlet 708 and flows along the slider 5, thus providing a lubricating effect. This automatic lubrication effect prevents... Excessive friction and stiffness during sliding can cause jamming, leading to sudden pulling or bending of the cable body 6. This can affect the internal structure of the cable body 6, thereby impacting the elevator's operation and potentially causing dangerous consequences. To avoid manual lubrication, lubrication is performed quickly and easily by periodically introducing lubricating oil into the storage box 702 via the delivery pipe 703. The cooperation between the connecting plate 8 and the contact roller 9 allows the cable body 6 to slide smoothly on both sides of the storage box 702, preventing excessive friction from causing jamming or bending.

[0030] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the sleeve 705 has an internal mounting groove 10, and the mounting groove 10 has a positioning mechanism 11. The positioning mechanism 11 includes a limiting cylinder 1101, which is fixed to the bottom of the mounting groove 10. An electromagnet 1102 is embedded in the bottom of the limiting cylinder 1101. A permanent magnet 1103 is fixedly installed at the bottom of the contact rod 704 corresponding to the position of the limiting cylinder 1101. A spring 1104 is fixedly installed on the outside of the permanent magnet 1103 at the bottom of the contact rod 704. A card plate 12 is fixedly installed at one end of the slider 5 that passes through the guide rail 1. An anti-collision pad 13 is embedded at the bottom of the gravity block 3.

[0031] By adopting the above technical solution, under normal circumstances, the elastic contraction of the spring 1104 drives the limiting cylinder 1101, allowing the sleeve 705 to be fitted onto the outer wall of the contact rod 704, preventing contact between the contact block 701 and the sleeve 705, and preventing automatic lubrication during normal elevator operation, which would lead to waste of lubricating oil. When lubrication is required, or when periodic maintenance lubrication is needed, the electromagnet 1102 is activated to push the permanent magnet 1103 with the same magnetic pole to slide stably along the limiting cylinder 1101, and the spring 1104 is fixed on the contact rod 704. Between the rod 704 and the limiting cylinder 1101, the spring 1104 is stretched, causing the sleeve 705 to slide along the abutting rod 704, so that the sleeve 705 can contact the abutting block 701 and push, so that the lubricating oil flows out for lubrication through pressure. Multiple guide rails 1 are set on the same straight line, and the long clamping plate 12 can slide between two guide rails 1, so that the corresponding mounting bracket 2 and gravity block 3 can be driven to slide through the slider 5, avoiding the large self-weight of the long guide rail 1 when using a single guide rail 1.

[0032] Working principle: The cable body 6 passes through the contact wheel 4. Due to the movement of the cable body 6 and the gravity of the gravity block 3, the mounting bracket 2 slides along the guide rail 1 via the slider 5, preventing wobbling and deviation. When the mounting bracket 2 reaches the top of the guide rail 1, it abuts against the sleeve 705 via the contact block 701, causing the contact rod 704 to drive the push plate 706 to slide inside the storage box 702. The sealing gasket 707 improves the seal to prevent lubricating oil leakage and squeezes lubricating oil through the oil outlet 708 into the guide rail 1, dripping onto the slider 5 and the clamping plate 12, providing lubrication and preventing jamming during sliding. Lubricating oil is periodically replenished from the outside via the delivery pipe 703. When the cable body 6 is located on both sides of the storage box 702, it is limited by the connecting plate 8 and slides against the contact roller 9, maintaining smooth operation. Inside the mounting groove 10 of the sleeve 705, a fixed limiting cylinder 1101 is fitted with an electromagnet 1102. Under normal circumstances, the sleeve 705 is driven by the elastic contraction of the spring 1104 to the outer wall of the contact rod 704. The limiting cylinder 1101 is fitted with a permanent magnet 1103 to allow the cable body 6 to run normally. When lubrication or periodic lubrication is required, the electromagnet 1102 is activated, and the magnet pushes the permanent magnet 1103 with the same magnetic pole, stretching the spring 1104 to make the sleeve 705 slide down the contact rod 704, so that the contact block 701 can contact the sleeve 705 to press out lubricating oil. The guide rail 1 is provided with multiple sets of the same axis and equally distributed to avoid the large self-weight of the whole. The long clamping plate 12 allows multiple sliders 5 to slide along multiple guide rails 1 at the same time to maintain stability. The bottom of the gravity block 3 is glued with an anti-collision pad 13 to reduce the severity of the impact after collision.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
