Optical fiber implantation traveling cable with signal transmission performance

Abstract

The invention discloses an optical fiber implantation traveling cable with signal transmission performance, which comprises a main body, a protector, a detector and a storage cavity, and is characterized in that the protector is mounted on the front surface of the main body, a lubricator is mounted on the inner bottom wall of the protector, a lubricating pipe is mounted on the outer wall of the lubricator, a protection pad is mounted on the inner wall of the main body, and the protector is mounted on the inner wall of the main body. And a detector is mounted on the inner wall of the main body, and a storage cavity is formed in the inner wall of the main body. According to the invention, the cable can be protected by installing the protector, when the internal cable is protected, the roller and the fixed shaft can deform when the cable slides and the protector is extruded, the buffer column moves downwards to drive the buffer spring to contract, and the buffer spring contracts to absorb part of impact energy, so that the cable is protected. In addition, a protection pad and a second spring can protect the cable when collision and deformation occur, and a protection column and a sponge pad achieve the protection function of the cable in the same way.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an optical fiber implanted traveling cable with signal transmission performance. Background technique [0002] Elevator traveling cables are professional cables in elevator operation. There are elevator traveling cables for video surveillance and elevator traveling cables for digital networks. This article mainly introduces elevator traveling cables for digital networks. Elevators are essential transportation equipment in high-rise buildings. , It is necessary to move up and down frequently, and the cables that provide working power for the elevator must also move up and down, and with the development of technology and the needs of people's work and life, some activities such as communication and monitoring are also required in the elevator; [0003] For this reason, in the high-speed movement of the elevator, the wind resistance of the cable is large, which makes the cable fre...

Problems solved by technology

The present invention can fundamentally and effectively solve the problem of vibration and swing of the accompanying cable during elevator operation by adding a fixing device at the lower part of the accompanying cable and simultaneously provide tension for the accompanying cable, and avoid collisions between the accompanying cable and hoistway components during movement. In order to avoid the risk of the accompanying cable being broken during the operation of the elevator, and at the same time improve the service life of the accompanying cable and ensure the smooth operation of the elevator", but most of the existing cables lack the breakage warning function, so that when the cable breaks, the working Personnel do not know where the fracture occurred;

[0008] 3. The patent document CN112420248A discloses a multifunctional flame-retardant composite accompanying cable, and the protection claim is "especially a multifunctional flame-retardant composite accompanying cable, including a first cable body and a second cable body. The first cable The main body and the second cable main body are arranged in parallel. There are multiple connecting rods connected between the first cable main body and the second cable main body. Conductors are arranged in the middle of the inner cavity of the first cable main body and the second cable main body. The outer wall of the wire is covered with an inner insulating layer, the outer wall of the inner insulating layer is covered with a fireproof filling layer, the outer wall of the fireproof filling layer is covered with an outer insulating layer, and the outer wall of the outer insulating layer is covered with a fireproof Layer, the multi-functional flame-retardant composite accompanying cable can prevent leakage accidents caused by the main body of the cable being connected to other objects due to the shedding of the surface layer, and has the effect of fire prevention and flame retardancy. However, most of the existing cables do not have a lubricating structure. Friction will occur in the middle, which will affect the service life;

[0009] 4. The patent document CN108417306A discloses an accompanying cable for elevators in low-rise buildings. The protection claim "includes: the first input joint, the first output joint and the main cable. The cross section of the main cable is circular or flat. The main cable is The cable includes sheath layer, braiding layer, control wire layer, shielding layer, main wire layer and steel wire from outside to inside, and also includes filler; the shape of the main cable is an Archimedes spiral; the first input connector is located on a disk The outer side of the main cable is fixed on the ground; the accompanying cable for low-rise building elevators of the present invention is arranged at the bottom of the elevator car in a disc shape. During the movement with the elevator, the deformation of each part of the accompanying cable is controlled. Within a certain range, the accompanying cable can have greater design freedom in terms of pipe diameter, internal pipeline material selection, and overall weight. It is lighter and thinner than ordinary accompanying cables, and it is better than ordinary accompanying cables in terms of life, space, and energy consumption. more advantages", but the existing cables lack fire-resistant and flame-retardant structures, and cannot promptly extinguish the fire or protect the internal cables in the event of a fire
