Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an anti-tangle device for elevator traveling cables. Background Technology

[0002] In an elevator system, a traveling cable is a special cable that is fixed at one end in the elevator shaft and connected to the other end, moving up and down with the elevator car. The cable forms a suspended U-shaped loop between the fixed end and the car, which ensures that when the car reaches the bottom floor, the cable will not be completely stretched and taut, but will still have buffer space. When the car reaches the top floor, the loop will not be excessively loose, thus avoiding interference with other components.

[0003] However, since the U-shaped loop is suspended between the hoistway and the car, and there are many elevator components between the hoistway and the car, the traveling cable is prone to swaying when the car moves up and down rapidly, which can easily cause it to get tangled with the elevator components, thus affecting the normal operation of the elevator to some extent. Utility Model Content

[0004] The main purpose of this utility model is to provide an anti-tangle device for elevator traveling cables, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An elevator traveling cable anti-tangle device includes a shaft and a cable body. The inner wall of the shaft is provided with a second guide mechanism for limiting movement. A car is provided in the shaft, and a first guide mechanism for support is provided on one side of the bottom of the car.

[0007] The first guiding mechanism includes a support frame, a fixed frame is fixedly disposed on one side inside the support frame, a first roller is rotatably disposed inside the fixed frame, a movable frame is slidably disposed inside the support frame away from the fixed frame, a second roller is rotatably disposed inside the movable frame, and the fixed frame and the movable frame are connected to each other by a buffer mechanism.

[0008] Preferably, one end of the cable body is fixed to the hoistway, and the other end is connected to the car. The cable body is supported by a first roller and a second roller, and the support frame is fixedly installed at the bottom of the car.

[0009] Preferably, the second guide mechanism includes a plurality of first mounting brackets and second mounting brackets. A spring telescopic rod is fixedly provided at one end of the second mounting bracket, and a fixing clamp is fixedly provided at one end of the inner rod of the spring telescopic rod.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example: Figure 1-5 As shown, an elevator traveling cable anti-tangle device includes a shaft 1 and a cable body 5, the cable body 5 being a traveling cable. The inner wall of the shaft 1 is provided with a second guide mechanism 4 for limiting movement. A car 2 is provided inside the shaft 1, and a first guide mechanism 3 for support is provided on one side of the bottom of the car 2.

[0026] The first guiding mechanism 3 includes a support frame 301, a fixed frame 302 is fixedly installed on one side of the support frame 301, and a first roller 303 is rotatably installed inside the fixed frame 302. The cable body 5 on the car 2 is fed into the U-shaped frame through the roller, which facilitates the reduction of the cable body 5 with a large range of motion and prevents it from getting tangled with elevator components. A movable frame 304 is slidably installed inside the support frame 301 away from the fixed frame 302. A second roller 305 is rotatably installed inside the movable frame 304. The fixed frame 302 and the movable frame 304 are connected to each other through a buffer mechanism 6.

[0027] Preferably, one end of the cable body 5 is fixed to the hoistway 1, and the other end is connected to the car 2. The cable body 5 is supported by a first roller 303 and a second roller 305. The support frame 301 is fixedly installed at the bottom of the car 2. The first roller 303 and the second roller 305 can change the moving position of the cable body 5. The cable body 5 can be sent into the second guide mechanism 4 to limit the narrow surface, which can ensure that the cable body 5 does not come into contact with other elevator components and prevent entanglement.

[0028] Preferably, the second guiding mechanism 4 includes a plurality of first mounting brackets 402 and second mounting brackets 404. A spring telescopic rod 405 is fixedly mounted at one end of the second mounting bracket 404. A fixing clamp 406 is fixedly mounted at one end of the inner rod of the spring telescopic rod 405. The fixing clamp 406 clamps the cable body 5, which, in conjunction with the spring telescopic rod 405, buffers the cable and reduces cable swaying. The fixing clamp 406 is connected to the cable body 5. Both the first mounting brackets 402 and the second mounting brackets 404 are fixedly mounted on the inner wall of the shaft 1. A U-shaped fixing bracket 403 is fixedly mounted on one side of the first mounting bracket 402. The U-shaped fixing bracket 403 and the mounting bracket facilitate the installation of the U-shaped frame 401. A U-shaped frame 401 is fixedly installed inside the cable body 5. The width of the inner wall of the U-shaped frame 401 is greater than the width of the cable body 5. The wide side of the cable body 5 can enter through the opening of the U-shaped frame 401, while the narrow side of the cable body 5 is limited to prevent shaking. At the same time, it is convenient for one end of the cable body 5 to move up and down with the car 2 to prevent the cable body 5 from getting tangled. One end of the spring telescopic rod 405 is connected to the U-shaped frame 401. Several through holes 407 are opened through the inner wall of the U-shaped frame 401. Through the through holes 407, when the cable body 5 enters the U-shaped frame 401, the air inside the cable body 5 and the U-shaped frame 401 can be discharged in time to prevent the air inside the U-shaped plate from generating a reaction force that causes the cable body 5 to shake.

[0029] Preferably, the buffer mechanism 6 includes a slide cylinder 601, inside which a slide rod 602 is slidably disposed. The slide rod 602 is fixedly disposed inside the lower end of the fixed frame 302. The slide cylinder 601 is fixedly disposed on one side of the lower end of the movable frame 304. A return spring 603 is fixedly disposed on one side of the inside of the slide cylinder 601 to facilitate the reset of the movable frame 304 on the slide cylinder 601. One end of the return spring 603 is fixedly disposed on one end of the slide rod 602. Specifically, the car 2 moves in the hoistway 1. During the ascent, the cable body 5 is buffered by the buffer mechanism 6 on the second roller 305. The cable body 5 pushes the moving frame 304 on the second roller 305 to move. Then, the moving frame 304 drives the slide cylinder 601 to move on the slide rod 602. At this time, the return spring 603 is compressed. When the cable rises instantaneously, the buffer mechanism 6, which carries the moving frame 304, deforms and converts the kinetic energy of the cable into elastic potential energy. After resetting, the energy is dissipated, ensuring the stability of the cable body 5 and preventing entanglement.

[0030] The cable body 5 is configured to be flat, which helps to reduce the tendency to tangle.

[0031] Working principle: When using this device, firstly, the cable body 5 on the car 2 is fed into the U-shaped frame through the first roller 303 and the second roller 305. When the car 2 rises in the hoistway 1, the cable body 5 is buffered by the buffer mechanism 6 on the second roller 305. The cable body 5 pushes the moving frame 304 on the second roller 305 to move. Then, the moving frame 304 drives the slide cylinder 601 to move on the slide rod 602. At this time, the return spring 603 is squeezed. When the force generated by the cable movement is buffered by the buffer mechanism 6, it is reset. When the car 2 descends, the cable body 5 moves into the U-shaped frame 401 of the second guide mechanism 4. Then, the air between the cable body 5 and the U-shaped plate is discharged through the through hole 407.
