Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail feeding technology, and more specifically, it relates to a feeding device for producing elevator guide rails. Background Technology

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates, and they are divided into car guide rails and counterweight guide rails. While providing guidance, the guide rails also withstand the impact forces during car and elevator braking, as well as the impact forces during emergency braking of the safety brake. Elevator guide rails are two or more vertical or inclined rigid rails installed in the elevator shaft or between floors, ensuring the vertical movement of the car and counterweight, and the inclined or horizontal movement of escalator and moving walkway steps, providing guidance for the elevator car, counterweight, or steps. As the definition of guide rails shows, they are crucial reference components for vertical elevators, escalators, and moving walkway steps. They control the running trajectory of the elevator car, escalator, and moving walkway steps, ensure the transmission of operating signals, and are vital components affecting elevator safety and operational quality.

[0003] In the production process of elevator guide rails, conveyor belts are typically used to transport elevator guide rail materials. The existing elevator guide rail feeding devices have a fixed conveyor belt length, which makes it inconvenient to adjust the conveyor belt length, to flexibly adjust it according to the distance between two workstations, and to install it between two workstations with different distances, thus reducing its practicality. In addition, the conveyor belts are all set horizontally, which makes it inconvenient to adjust the height of the output end of the conveyor belt, and to transport the elevator guide rails to workstations at different heights.

A second rotating roller 7 is rotatably connected to the adjusting seat 6. A first fixed seat 8 is fixedly connected to each of the two horizontal seats 1, and each of the two first fixed seats 8 is equipped with a... The system is equipped with a first electric cylinder 9, and two second fixed seats 10 are fixedly connected to each of the two first electric cylinders 9. The two second fixed seats 10 are fixedly connected to two adjusting seats 6 respectively. Each of the two horizontal seats 1 is provided with a vertical groove 11. A vertical plate 12 is slidably arranged inside each of the two vertical grooves 11. A third rotating roller 13 is rotatably connected to the bottom side of the middle of the vertical plate 12. The conveyor belt 2 is connected to the first rotating roller 3, the second rotating roller 7 and the third rotating roller 13. A top plate 14 is fixedly connected to the top of each of the two vertical plates 12. Two second electric cylinders 15 are connected between the top plate 14 and the horizontal seat 1.

[0030] Specifically, four second electric cylinders 15 drive two top plates 14, two vertical plates 12, and a third rotating roller 13 to move up and down, adjusting the tension of the conveyor belt 2. Two first electric cylinders 9 push two adjusting seats 6 to move, adjusting the distance between the first rotating roller 3 and the second rotating roller 7, thereby adjusting the length of the conveyor belt 2 between the first rotating roller 3 and the second rotating roller 7. This makes it easy to adjust the conveyor belt 2 to a suitable length according to the distance between two workstations, thus facilitating installation between two workstations with different distances and enabling material feeding of the elevator guide rail between workstations with different distances, improving its practicality.

[0031] Please see Figures 1-4 The bottom ends of the two horizontal seats 1 are fixedly connected to a first support frame 16. The bottom ends of the first support frame 16 are rotatably connected to a support base 17 to support the two horizontal seats 1. The bottom ends of the support base 17 are fixedly connected to a first base 18. The first base 18 is provided with multiple fixing grooves 19 to facilitate fixing the first base 18 to the ground with expansion screws. The two adjusting seats 6 are fixedly connected to a second support frame 20. The bottom ends of the second support frame 20 are rotatably connected to a U-shaped seat 21.

The second base 24 is rotatably connected to multiple rollers 25 to facilitate the movement of the second base 24 on the ground.

[0032] Specifically, the first support frame 16 is rotatably connected to the support base 17, and the second support frame 20 is rotatably connected to the U-shaped base 21. The horizontal plate 22 and the U-shaped base 21 are moved up and down by four third electric cylinders 23, which at the same time drive the height of the two adjusting seats 6 and the second rotating roller 7 to be adjusted, so as to facilitate the adjustment of the height of the conveyor belt 2 at the position of the second rotating roller 7, and facilitate the transport of the elevator guide rail to workstations at different heights.

[0033] Please see Figure 1 , Figure 2 and Figure 5 The top of the second base 24 is fixedly connected to a fixed frame 26. A lifting plate 27 is slidably arranged inside the fixed frame 26.

[0035] In summary, when using the overall equipment:

[0036] When the length of the conveyor belt 2 needs to be adjusted, the two top plates 14, the two vertical plates 12 and the third roller 13 are pushed upward by the four second electric cylinders 15 to make the conveyor belt 2 slack. Then, the two first electric cylinders 9 are pushed to move the two adjusting seats 6 and the second roller 7 to adjust the first roller 3 and the second roller 7 to a suitable distance. Then, the four electric cylinders pull the two top plates 14, the two vertical plates 12 and the third roller 13 downward, and the third roller 13 pulls the conveyor belt 2 downward to adjust the conveyor belt 2 to a suitable tension.

[0037] When it is necessary to adjust the height of the elevator guide rail, the two adjusting seats 6 and the second rotating roller 7 are moved up and down by the four third electric cylinders 23, and the second rotating roller 7 is adjusted to a suitable height, so that the elevator guide rail at the position of the first rotating roller 3 is transported to the corresponding height.
