DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-4 As shown, an elevator installation wire laying device includes a mounting plate 1. On the top side of the mounting plate 1, two groups of two supporting plates 2 are symmetrically installed. Inside the supporting plates 2, guiding rollers 3 are installed through pin shaft cooperation. On the outer side of the guiding rollers 3, friction sensors 4 are installed. On the top side of the supporting plates 2, a mounting frame 5 is jointly installed. Between the two sides of the mounting frame 5, a rotating shaft 6 is rotatably installed. On the outer side of the rotating shaft 6, a sponge roller 7 is installed. At both ends of the top side of the mounting plate 1 and between the two supporting plates 2, oil storage cavities 8 are installed. The bottom end of the oil storage cavity 8 is connected with a connecting pipe 9. One end of the connecting pipe 9 penetrates into the interior of the mounting frame 5 and is in contact with the sponge roller 7. A micro pump 10 is installed on the outer wall of the connecting pipe 9. Between the two sides of the supporting plate 2 and below the guiding roller 3, a funnel 11 is installed. The bottom end of the funnel 11 is communicated with the oil storage cavity 8. At the edge of the top side of the mounting plate 1, a control panel 31 is installed. During operation, in practical applications, as the service time of the steel wire rope 28 extends, the friction between the steel wire rope 28 and the guiding roller 3 increases significantly, resulting in a greater resistance when the steel wire rope 28 is running, affecting the smoothness of elevator installation wire laying and shortening its service life. When the steel wire rope 28 runs on the guiding roller 3, the friction sensor 4 monitors the friction of the steel wire rope 28 on the guiding roller 3. When the friction sensor 4 detects that the friction increases to a certain extent, the control panel 31 sends an operation control signal to the micro pump 10. The micro pump 10 starts, and conveys the lubricating oil in the oil storage cavity 8 to the sponge roller 7 through the connecting pipe 9. As the sponge roller 7 rotates with the rotating shaft 6, the lubricating oil is evenly applied to the passing steel wire rope 28, realizing automatic lubrication, effectively reducing the wear of the steel wire rope 28, ensuring its normal operation and service life. The excess lubricating oil applied to the steel wire rope 28 will drip into the funnel 11 and then flow back to the oil storage cavity 8, realizing the recycling of the lubricating oil. Among them, the model of the friction sensor 4 is the CPR016 circular friction force measuring sensor.

[0024] Please refer to Figure 1 、 2 As shown in Fig. 5, at the middle edge of the top side of the mounting plate 1, a fixing plate 12 is installed. Inside the fixing plate 12, a rotating shaft 13 is rotatably installed through it. On the outer side of one end of the rotating shaft 13, a wire laying roller 14 is installed. On the top side of the mounting plate 1, two side plates 15 are symmetrically installed. On one side of the side plate 15, a servo motor 16 is installed. The output end of the servo motor 16 is installed with a worm 17. On the outer side of the other end of the rotating shaft 13, a worm gear 18 is installed, and the worm gear 18 meshes with the worm 17.

[0025] A groove 19 is formed inside the middle end of the mounting plate 1. A threaded rod 20 and a guide rod 21 are respectively rotatably mounted and fixedly mounted on the inner wall of the bottom side of the groove 19. A handle 22 is mounted on the top side of the threaded rod 20. A connecting plate 23 is movably mounted on the outer sides of the threaded rod 20 and the guide rod 21. Two mounting seats 24 are mounted at both ends of the top side of the connecting plate 23. A tension roller 25 is mounted inside the mounting seat 24 through pin shaft cooperation.

[0026] Through grooves 26 are formed inside both ends of the mounting plate 1. Two wire guide rollers 27 are symmetrically mounted inside the through grooves 26 through pin shaft cooperation. A steel wire rope 28 is assembled outside the wire pay-off roller 14. Both ends of the steel wire rope 28 respectively pass through the bottom side of the tension roller 25 and extend to the top side of the guide roller 3, and then extend below the mounting plate 1 from between the two wire guide rollers 27. Counterweight blocks 29 and an elevator car 30 are respectively mounted at both ends of the steel wire rope 28. During operation, during the operation of the elevator, precise wire pay-off can ensure the stability and safety of the car and the counterweight during operation, and reduce the friction caused by position deviation. Therefore, a wire pay-off device is required. By rotating the handle 22 on the top side of the threaded rod 20, the threaded rod 20 can be rotated, and the connecting plate 23 will move up and down with the rotation of the threaded rod 20, thereby driving the tension roller 25 to move up and down, realizing the adjustment of the tension of the steel wire rope 28, so that the steel wire rope 28 can maintain an appropriate tension under different working conditions, ensuring the stability of the wire pay-off process.

[0027] After the servo motor 16 is started, its output end drives the worm 17 to rotate. The worm 17 meshes with the worm gear 18, thereby driving the worm gear 18 to rotate, and then driving the rotating shaft 13 to rotate. The wire pay-off roller 14 on the rotating shaft 13 starts to release the steel wire rope 28 with the rotation of the rotating shaft 13. And the worm 17 and worm gear 18 structure has a self-locking characteristic. When the servo motor 16 stops working, it can effectively prevent the wire pay-off roller 14 from reversing, and can avoid the accidental loosening of the steel wire rope 28, improving the safety performance of the elevator operation. After the steel wire rope 28 is released from the wire pay-off roller 14, both ends respectively pass through the bottom side of the tension roller 25, then extend to the top side of the guide roller 3, and then pass through between the two wire guide rollers 27 and extend below the mounting plate 1. The wire guide rollers 27 play a role in guiding the steel wire rope 28 to run along a predetermined path, and can also disperse the tension borne by the steel wire rope 28 during operation, extending the service life of the steel wire rope 28.

[0028] Working principle: By rotating the handle 22 on the top side of the threaded rod 20, the threaded rod 20 can be rotated, and the connecting plate 23 will move up and down with the rotation of the threaded rod 20, thereby driving the tension roller 25 to move up and down, realizing the adjustment of the tension of the steel wire rope 28, so that the steel wire rope 28 can maintain an appropriate tension under different working conditions, ensuring the stability of the wire pay-off process.

[0029] After the servo motor 16 is started, the output end thereof drives the worm 17 to rotate. The worm 17 meshes with the worm gear 18, thereby driving the worm gear 18 to rotate, and further driving the rotating shaft 13 to rotate. The wire reel 14 on the rotating shaft 13 starts to release the wire rope 28 as the rotating shaft 13 rotates. Moreover, the worm 17 and worm gear 18 structure has a self-locking characteristic. When the servo motor 16 stops working, it can effectively prevent the wire reel 14 from rotating in reverse, avoid the accidental loosening of the wire rope 28, and improve the safety performance of the elevator operation. After the wire rope 28 is released from the wire reel 14, both ends pass through the bottom side of the tension roller 25 respectively, then extend to the top side of the guide roller 3, and then pass through the middle of the two wire guide rollers 27 and extend to the lower side of the mounting plate 1. The wire guide rollers 27 play a role in guiding the wire rope 28 to run along a predetermined path, and at the same time can also disperse the tension borne by the wire rope 28 during operation, extending the service life of the wire rope 28;

[0030] When the wire rope 28 runs on the guide roller 3, the friction sensor 4 monitors the friction force of the wire rope 28 on the guide roller 3. When the friction sensor 4 detects that the friction force increases to a certain extent, the control panel 31 sends an operation control signal to the micro pump 10. The micro pump 10 is started, and the lubricating oil in the oil storage cavity 8 is conveyed to the sponge roller 7 through the connecting pipe 9. As the sponge roller 7 rotates with the rotating shaft 6, the lubricating oil is evenly applied to the passing wire rope 28, realizing automatic lubrication, effectively reducing the wear of the wire rope 28, ensuring its normal operation and service life. The excess lubricating oil applied to the wire rope 28 will drip into the funnel 11 and then flow back to the oil storage cavity 8, realizing the recycling of the lubricating oil.
