Description

Technical Field

[0001] This utility model relates to the field of traveling cable technology, and in particular to a traveling cable suitable for high-speed elevators. Background Technology

[0002] Traveling cables are special cables used in elevator systems. They connect the elevator car to electrical equipment in the elevator machine room or shaft wall. Their main function is to provide power to the elevator car and transmit data signals during its movement. They are typically flat or round to better adapt to the space of the elevator shaft and the car's operating mode. Flat cables can be easily laid along the car or shaft wall, occupying less space.

[0003] One end of the elevator traveling cable is connected to the machine room control cabinet, and the other end is fixed to the elevator car and moves with the elevator car. When the elevator goes up or down, the cable that provides power to the elevator also moves up and down with it. At the same time, when the elevator car is running in the shaft, the traveling cable will bend continuously as the car rises and falls.

[0004] Existing technical solutions, when implemented, use cable clamps to allow the elevator to adapt to the bending and stretching of the cable, while avoiding excessive compression or damage to the cable. This solution allows the elevator and the traveling cable to move together. However, for high-speed elevators, due to the high speed, there will be downward inertia, which may cause the traveling cable near the bottom of the elevator to vibrate, and then collide or even become entangled. Summary of the Invention

[0005] The purpose of this invention is to provide a traveling cable suitable for high-speed elevators, which enables the cable body to be transported stably and avoids excessive shaking between cable bodies caused by the inertia generated by the high speed of the elevator, thereby preventing entanglement and collision and damage to the cable body, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traveling cable suitable for high-speed elevators, comprising a mounting plate, wherein a first ring is fixedly mounted on the front end of the mounting plate, and a cable body extends through the inside of the first ring, and a limiting mechanism is provided below the first ring.

[0007] The limiting mechanism includes a connecting frame, which is fixed to one side of the bottom end of the first collar. An installation hole is provided inside the connecting frame, and a support rod is fixedly installed inside the installation hole. A rotating rod is rotatably connected to the outer wall of the support rod. A first spring is embedded in one side of the outer wall of the rotating rod, and a rotating cylinder is rotatably connected to the bottom end of the rotating rod.

[0008] Preferably, a connecting plate is fixedly installed on the inner wall of the first collar, and an abutting roller is rotatably connected to the outer wall of the connecting plate.

[0009] Preferably, the rotating rod and the support rod form a rotating structure, and the rotating rod and the connecting frame form an elastic structure through the first spring.

[0010] Preferably, a connecting rod is fixedly installed at the front end of the first collar, and a second collar is fixedly installed at the front end of the connecting rod.

[0011] Preferably, a bearing mechanism is provided below the connecting rod. The bearing mechanism includes a connecting rod, which is rotatably connected to the outer wall of the connecting rod. A rotating plate is rotatably connected to one end of the connecting rod that passes through the connecting rod, and a connecting shaft extends out from the interior of the rotating plate.

[0012] Preferably, a through rod extends from the inside of the connecting rod, and a second spring is embedded at one end of the through rod.

[0013] Preferably, a telescopic plate is fixedly installed on one side of the bottom end of the second ring, and an abutment plate is fixedly installed below the telescopic plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model separates the moving cable body through the first and second sets of rings, and with the cooperation of the rotating cylinder and the contact roller, it can stably transport the cable body and avoid excessive shaking between the cable bodies caused by the inertia generated by the high speed of the elevator, which could lead to entanglement and collision and damage to the cable body.

[0016] 2. This utility model uses a telescopic plate and a stop plate to prevent the cable bodies on both sides from getting close to each other, thus effectively avoiding entanglement. At the same time, the elastic contraction of the second spring allows the telescopic plate to contract when the elevator reaches the bottom floor, preventing the stop plate from hitting the ground and affecting the stability of the elevator after it stops.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3A traveling cable suitable for high-speed elevators includes a mounting plate 1. A first ring 2 is fixedly mounted on the front end of the mounting plate 1. A cable body 3 extends through the inside of the first ring 2. A limiting mechanism 4 is provided below the first ring 2. The limiting mechanism 4 includes a connecting frame 401, which is fixed to one side of the bottom end of the first ring 2. A mounting hole 402 is provided inside the connecting frame 401. A support rod 403 is fixedly mounted inside the mounting hole 402. A rotating rod 404 is rotatably connected to the outer wall of the support rod 403. A first spring 405 is embedded on one side of the outer wall of the moving rod 404. A rotating cylinder 406 is rotatably connected to the bottom end of the rotating rod 404. A connecting plate 407 is fixedly installed on the inner wall of the first collar 2. An abutting roller 408 is rotatably connected to the outer wall of the connecting plate 407. The rotating rod 404 and the support rod 403 form a rotating structure. The rotating rod 404 and the connecting frame 401 form an elastic structure through the first spring 405. A connecting rod 5 is fixedly installed at the front end of the first collar 2. A second collar 6 is fixedly installed at the front end of the connecting rod 5.

[0028] By adopting the above technical solution, the cable body 3 is first limited by the first ring 2, and the cable body 3 on the other side is limited by the connecting rod 5 and the second ring 6 to prevent them from getting close to each other. At the same time, the support rod 403 and the rotating rod 404 inside the mounting hole 402 of the connecting frame 401 are rotatably connected. Under the elastic support of the first spring 405, the rotating cylinder 406 can abut against the outer wall of the cable body 3. With the help of the connecting plate 407 and the abutting roller 408, the cable body 3 is limited. This allows the cable body 3 to avoid deviation and excessive shaking when it moves at high speed with the elevator, which could cause collisions with other components and damage to the internal structure, or entanglement with other components, which could lead to dangerous situations during elevator operation.

[0029] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a bearing mechanism 7 is provided below the connecting rod 5. The bearing mechanism 7 includes a connecting rod 701, which is rotatably connected to the outer wall of the connecting rod 5. A rotating plate 702 is rotatably connected to one end of the connecting rod 701 that passes through the connecting rod 5. A connecting shaft 703 extends out of the interior of the rotating plate 702. A through rod 704 extends out of the interior of the connecting rod 701. A second spring 705 is embedded in one end of the through rod 704 located on the connecting rod 701. A telescopic plate 706 is fixedly installed on one side of the bottom end of the second collar 6. An abutment plate 707 is fixedly installed below the telescopic plate 706.

[0030] By adopting the above technical solution, a telescopic rod is first formed by connecting rod 701 and through rod 704. Connecting rod 701 and through rod 704 are rotatably connected to connecting rod 5 and contact plate 707 respectively through corresponding rotating plate 702 and connecting shaft 703. Under the elastic support of second spring 705, telescopic plate 706 can extend and contact with contact plate 707 on one side of cable body 3, avoiding swaying that could cause collision or entanglement with cable body 3 on the other side. At the same time, when the elevator descends to the bottom floor, contact plate 707 contacts the ground. The connecting rod 701 and through rod 704 compress second spring 705 to retract, and telescopic plate 706 drives contact plate 707 to extend and retract. The rotating plate 702 and connecting shaft 703 automatically adjust the angle, thereby avoiding contact between contact plate 707 and the ground, which would prevent the elevator from stopping.

[0031] Working principle: The cable body 3 is easily fixed to the elevator via mounting plate 1 and bolts. Simultaneously, the first ring 2, connecting rod 5, and second ring 6 separate the cable body 3 to prevent entanglement. Both the first ring 2 and second ring 6 are limited by the embedded connecting plate 407, and the contact roller 408 improves the smoothness of the conveying process. The first ring 2 fixes the support rod 403 through the mounting hole 402 in the connecting frame 401. The rotating rod 404, rotatably connected to the support rod 403, is elastically pushed by the first spring 405, causing the rotating roller 406 to contact the cable body 3, facilitating the holding of the cable body 3 during conveying. To ensure stability and prevent excessive shaking, connecting rod 701 is rotatably connected to connecting rod 5 via rotating plate 702 and connecting shaft 703. Through rod 704 is rotatably connected to contact plate 707 via rotating plate 702 and connecting shaft 703. Under the elastic push of second spring 705, connecting rod 701 and through rod 704 support contact plate 707, allowing telescopic plate 706 to unfold. When the elevator reaches the bottom, contact plate 707 touches the ground base. Through the cooperation of rotating plate 702 and connecting shaft 703, connecting rod 701 and through rod 704 can adjust their angles to allow telescopic plate 706 to extend and retract, preventing collisions and limiting movement.

[0032] 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.
