Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, and particularly relates to a centering mechanism for elevator guide rail processing. Background Technique

[0002] An elevator guide rail is an elevator component composed of a steel rail and a connecting plate, and is divided into a car guide rail and a counterweight guide rail. It is divided into three forms in terms of cross-sectional shape: T-shaped, L-shaped, and hollow. While playing a guiding role, the guide rail bears the impact force during the movement of the car and when the elevator brakes, as well as the impact force when the safety clamp makes an emergency brake. The magnitudes of these forces are related to the load capacity and speed of the elevator. Therefore, the guide rail should be selected according to the elevator speed and load capacity.

[0003] During the processing of elevator guide rails, due to machine vibration, the guide rail moves unstably in the equipment, resulting in misalignment and uneven surface of the produced guide rail, which will make the elevator run unevenly during operation and also pose a safety hazard.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the 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 shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 9, the present utility model provides a centering mechanism for elevator guide rail processing, including a housing 1. A frame 11 is slidably connected inside the housing 1. A fixed column 4 is slidably connected inside the frame 11. A fixing plate A5 is fixedly installed above the fixed column 4. When the frame 11 moves downward, the fixed column slides inside the frame 11 to change the height of the fixing plate A5, achieving the effect of fixing the guide rail. A fixing plate B7 is fixedly installed on the frame 11. A motor B8 is connected through the middle of the fixing plate B7. An electric sliding plate 17 is fixedly connected to the motor B8. A connecting plate 12 is slidably connected to the electric sliding plate 17. The motor B8 can drive the connecting plate 12 to slide on the electric sliding plate 17, achieving the effect that the connecting plate 12 can slide normally. A detection block A13 is fixedly connected inside the lower part of the connecting plate 12. A spring A14 is fixedly connected to the side of the detection block A13. A connecting block 19 is fixedly connected above the detection block A13. A detection block B15 is fixedly connected above the connecting block 19. A spring B16 is fixedly connected to the detection block B15. When the detection block A13 expands and contracts through the spring A14, it drives the connecting block 19, and the detection block B15 will also expand and contract through the spring B16. Through the sliding of the connecting plate 12, when the detection block A13 encounters the uneven surface of the guide rail and retracts through the spring A14, it indicates that the surface of the guide rail is not smooth. When the detection block A13 retracts through the spring A14, it drives the connecting block 19 to make the detection block B15 also retract through the spring B16, achieving the effect of detecting where the guide rail is not smooth. A U-shaped plate 6 is fixedly connected to the frame 11. A rolling shaft 10 is connected through the middle of the U-shaped plate 6. The rolling shaft 10 is connected through the fixing plate B7. A long plate 18 is fixedly connected to one side of the rolling shaft 10. The rolling shaft 10 moves parallel inside the U-shaped plate 6 and also moves up and down inside the fixing plate B7. By the movement of the rolling shaft 10, the distance between the long plates 18 is changed. When the rolling shaft 10 can move to a qualified position in the U-shaped plate 6 and the fixing plate B7, it indicates that the centering detection of the guide rail is qualified. On the contrary, when the rolling shaft 10 cannot move to a qualified position in the U-shaped plate 6 and the fixing plate B7, it indicates that the centering detection of the guide rail is unqualified, achieving the effect of detecting the centering qualification of the guide rail.

[0028] A motor A2 is installed on the frame 11. The motor A2 is connected through the housing 1. The motor A2 drives the frame 11 to slide inside the housing 1, achieving the effect of equipment operation. The lower part of the fixed column 4 is fixedly connected to the housing 1. A base 3 is fixedly connected inside the housing 1, achieving the effect of placing the guide rail.

[0029] The outer shell 1 is provided with a sliding groove B21, and the connecting plate 12 slides on the outer shell 1 through the sliding groove B21; the frame 11 is provided with a sliding groove A20, and the connecting plate 12 slides on the frame 11 through the sliding groove A20, so that the connecting plate 12 can express the guide rail detection situation to the outside of the device through the sliding groove A20 and the sliding groove B21 during the sliding process; when the connecting plate 12 slides, the detection block B15 and the detection block A13 are retracted when encountering an obstacle, and the detection block B15 and the detection block A13 rebound and extend through the spring A14, achieving the effect of detecting whether the surface of the guide rail is smooth; the movement of the detection block B15 and the detection block A13 drives the connecting block 19, so that the detection block B15B is also retracted, and the detection block B15B rebounds and extends through the spring B16, achieving the effect of detecting where the surface of the guide rail is not smooth; the motor B8 drives the connecting plate 12 to slide on the electric sliding plate 17, achieving the effect that the connecting plate 12 can detect the entire guide rail.

[0030] The frame 11 is fixedly installed with a bolt 9, and the fixing plate B7 is fixedly installed on the frame 11 through the bolt 9, achieving the effect that the movement of the frame 11 can drive the movement of the fixing plate B7; the movement of the fixing plate B7 drives the movement of the rolling shaft 10, and the movement of the rolling shaft 10 drives the movement of the long plate 18, making the distance between the long plates 18 smaller, achieving the effect of centering and inspecting the guide rail.

[0031] Working principle: When using the device, the guide rail is placed on the base 3, and the motor A2 is started. The motor A2 drives the frame 11 to press down. When the frame 11 presses down, it will change the length of the fixed column 4 and cause the height of the fixing plate A5 to change. When the frame 11 presses down, it will also drive the connecting plate 12 to descend. When the frame 11 presses down, the fixing plate A5 and the connecting plate 12 simultaneously achieve the effect of fixing the guide rail; when the frame 11 presses down, the rolling shaft 10 will move parallel in the U-shaped plate 6 and also move upward in the fixing plate B7. The movement of the rolling shaft 10 changes the distance between the long plates 18, achieving the effect of detecting the centering of the guide rail; when the rolling shaft 10 can move to a qualified position in the fixing plate B7, the motor B8 is started. When the rolling shaft 10 moves to a suitable position, the connecting plate 12 slides on the electric sliding plate 17 to detect the smoothness of the surface of the guide rail. When the connecting plate 12 encounters an uneven situation during the sliding process, the detection block A13 is retracted through the spring A14. The retraction of the detection block A13 drives the connecting block 19 to cause the detection block B15 to be retracted through the spring B16. After passing through the unevenness, the detection block A13 rebounds through the spring A14. The rebound of the detection block A13 drives the connecting block 19 to cause the detection block B15 to rebound through the spring B16, achieving the effect of detecting where the surface of the guide rail is not smooth. There is a detection block B15 above the sliding groove A20 and the sliding groove B21 of the connecting plate 12. The detection block B15 shows where the guide rail is not smooth to the outside of the device through the expansion and contraction of the spring B16.
