[0002] Elevators are essential means of transportation in high-rise buildings. Elevator traveling cables are specialized cables used in elevator operation. They are installed under the elevator car to connect the elevator car and the elevator machine room. They are uninterrupted cables responsible for transmitting information such as electricity, signals, and data required for the elevator to operate. Traveling cables usually contain steel wire tensioning components, which can effectively solve the problem of breakage or damage that may occur due to external forces on wires and cables during elevator operation.

[0003] The defects of elevator accompanying cables in the prior art are:

[0004] 1. Patent document JP2018197166A discloses an elevator moving cable and an elevator system. The elevator moving cable does not have a bending guide structure when in use, which is not conducive to maintaining the shape of the cable and increases the curvature of the cable. It is susceptible to damage due to excessive bending or twisting during movement. Interference and friction will occur due to swinging or twisting, and the stability and reliability of the elevator operation cannot be guaranteed.

[0005] 2. Patent document CN211687854U discloses an elevator traveling cable protection device, which cannot scrape off liquid and dust on the outer surface of the traveling cable. Corrosive liquid and dust can easily damage the outer surface of the traveling cable, causing cable aging and degradation of insulation performance, thus shortening the service life of the traveling cable.

[0006] 3. Patent document CN105366461B discloses an elevator traveling cable protection device, which cannot guide and restore the elevator traveling cable that is bent during movement, resulting in uneven force on the conductor and insulation layer inside the traveling cable, which is prone to signal attenuation or power loss due to bending, and cannot ensure that the cable maintains stable performance when transmitting power and signals.

[0007] 4. Patent document CN220874169U discloses an elevator traveling cable protection device, which cannot lubricate the inner and outer surfaces of the traveling cable. The bending and stretching of the traveling cable during the operation of the elevator will generate friction, which accelerates the wear rate of the traveling cable.

The bending protection component cooperates with the arc guide seat to bend and guide the accompanying cable, which helps to maintain the shape of the cable and effectively reduce the curvature of the cable. The bending protection component disperses the load of the cable and further reduces the curvature of the cable, thereby reducing damage to the accompanying cable and increasing its service life, effectively preventing the cable from being excessively bent or twisted during movement, and protecting the conductor and insulation layer inside the cable from damage. The bending protection component bends and guides the cable to ensure that the cable maintains a relatively stable shape during movement, reduces interference and friction that may be caused by swinging or twisting, and helps to improve the stability and reliability of the elevator operation. Correct bending guidance reduces signal attenuation and interference during cable transmission, and maintains stable transmission of power and signals.

[0029] The present invention installs a cleaning rubber scraper seat on the top of the arc guide seat. During the bending and moving process of the accompanying cable, the cleaning rubber scraper seat scrapes off the liquid and dust on the outer surface of the accompanying cable. The scraped liquid and dust are collected in a collecting tank. The outer surface of the accompanying cable is classified and cleaned to prevent the corrosive liquid and dust in the elevator shaft from damaging the outer surface of the accompanying cable, resulting in cable aging, reduced insulation performance and other problems, thereby extending the service life of the accompanying cable. Cleaning the corrosive liquid and dust on the outer surface of the cable ensures the normal operation of the cable, reduces elevator failures and downtime caused by cable problems, improves the operation stability of the elevator, promptly discovers and handles potential safety hazards to ensure the safe operation of the elevator, and classified cleaning makes the cleaning work more targeted.

The elevator accompanying cable is guided by a bending recovery frame and a guide wheel after being bent, and the bending direction is adjusted to make it flat, so that the conductor and the insulation layer inside the accompanying cable are evenly stressed, and damage caused by local excessive bending is avoided, thereby extending the service life of the accompanying cable, ensuring that the cable maintains stable performance when transmitting power and signals, reducing signal attenuation or power loss caused by bending, and maintaining stable cable performance. The flatness of the cable can reduce potential safety hazards caused by friction or extrusion, thereby improving the safety performance of the elevator during operation. The flat cable is easier to carry out daily inspection and maintenance work, reduces the difficulty and cost of maintenance, and improves the overall operation efficiency of the elevator system.

[0031] The present invention provides a lubrication and leveling component on the inner side of the accompanying through-hole. When the accompanying cable moves out from another group of accompanying through-holes, the lubrication and leveling component wipes and lubricates the inner surface and outer wall of the accompanying cable through the lubrication wiping pad. The bending and extension of the accompanying cable during the operation of the elevator will generate friction. Proper lubrication reduces friction, thereby reducing the wear rate of the accompanying cable, thereby extending the service life of the accompanying cable. Good lubrication can ensure that the cable maintains sufficient flexibility and elasticity when bending and extending, avoiding additional stress concentration and damage caused by stiffness or jamming. Lubrication can reduce the resistance of the cable during operation, making the elevator system run more smoothly, thereby improving the operation efficiency of the elevator. The use of wiping lubrication will not cause excessive adhesion of lubricant on the surface of the accompanying cable, which will have an adverse effect on its use process.

[0046] The invention comprises a traveling cable 1, a transparent protective shell 2 and a bending protection component. The traveling cable 1 is composed of a conductor 8, an insulating layer 9 and a sheath 10. The insulating layer 9 is wrapped around the outside of the conductor 8, and the sheath 10 is wrapped around the outside of the insulating layer 9. The outside of the traveling cable 1 is installed with a transparent protective shell 2. The top of the transparent protective shell 2 is symmetrically penetrated with a traveling through hole 11, and the traveling cable 1 passes through the inside of the traveling through hole 11.

The traveling cable 1 is sleeved on the outer side of the traveling roller 16, and the traveling roller 16 cooperates with the arc guide seat 4;

[0047] The conductor 8 is mainly used for conducting current and is usually made of conductive materials such as copper or aluminum. The cross-sectional area of ​​the conductor 8 determines the current carrying capacity. The insulating layer 9 is mainly used to isolate the potential difference between the conductors 8 to prevent current leakage or short circuit. The sheath 10 is used to protect the internal structure of the cable from mechanical damage or the influence of the external environment. When the elevator is operating normally, the accompanying cable 1 moves up and down with the elevator car.

[0051] The accompanying cable 1 continues to move inside the transparent protective shell 2 after being guided by the bending protection component. The horizontal push groove 5 provides an installation position for the horizontal push plate 18. During the continuous movement of the accompanying cable 1, the bending recovery component gradually adjusts the bending direction of the accompanying cable 1 through the guide wheel 21 to restore it to flatness. The distance adjustment groove 22 provides an installation position for the distance adjustment telescopic rod 23.

Two sets of flat lubrication frames 6 are symmetrically installed on the inner side of the accompanying through-hole 11, and only one set has a lubrication structure to lubricate the inner surface and outer wall of the accompanying cable 1. The lubricant in the storage cylinder 7 is stored in the flat lubrication frame through the supply channel 40. 6, and flows into the lubricating wiping pad 38 through the lubrication hole 36 and is absorbed by it. The lubricating wiping pad 38 wipes and lubricates the inner surface and outer wall of the traveling cable 1. The bending and stretching of the traveling cable 1 during the operation of the elevator will generate friction. Proper lubrication reduces friction, thereby reducing the wear rate of the traveling cable 1. Good lubrication can ensure that the cable maintains sufficient flexibility and elasticity when bending and stretching, and avoids additional stress concentration and damage caused by stiffness or jamming. Lubrication can reduce the resistance of the cable during operation, making the elevator system run more smoothly. The use of wiping lubrication will not cause excessive adhesion of lubricant on the surface of the traveling cable 1, which will have an adverse effect on its use process.

[0070] Working principle: When using this device, first, when the elevator is operating normally, the accompanying cable 1 moves up and down with the elevator car, and the accompanying cable 1 enters the transparent protective shell 2 from the accompanying through-hole 11 and bends, and the bending protection component cooperates with the arc guide seat 4 to bend and guide the accompanying cable 1;

[0071] During the bending movement of the accompanying cable 1, the cleaning rubber scraper 24 scrapes the liquid and dust on the outer surface of the accompanying cable 1, and the scraped liquid and dust are collected in the collection tank 17. The accompanying cable 1 continues to move after being guided by the bending protection component. The bending recovery component gradually adjusts the bending direction of the accompanying cable 1 through the guide wheel 21 to restore it to flatness, and the adjustable telescopic rod 23 works to adjust the use position of the bending recovery frame 20;

[0072] When the accompanying cable 1 is moved out from another group of accompanying through-holes 11, the lubrication and leveling assembly wipes and lubricates the inner and outer surfaces of the accompanying cable 1 through the lubrication wiping pad 38. When the accompanying cable 1 is moved out from the transparent protective shell 2, the accompanying cable 1 after the bending recovery treatment is further leveled through the conductive plate 35 while being lubricated.
