Description

Technical Field

[0001] This application relates to the field of guide rail processing, and in particular to a straightening device for elevator guide rails. Background Technology

[0002] After undergoing processes such as high-speed broaching and back milling, most elevator guide rails still fail to meet the specified requirements. In such cases, the guide rails need to be corrected to ensure their flatness, thereby guaranteeing the safe operation of the elevator and improving its safety factor.

[0003] A search revealed a Chinese patent with authorization announcement number CN214184714U, which discloses an elevator guide rail correction device, including a base plate. A support rod and two support plates are fixedly connected to one side of the base plate. A testing platform is fixedly connected to the end of the support rod away from the base plate. A guide rail is provided on the side of the testing platform away from the support rod. An electric push rod is fixedly connected to one side of the support plate.

[0004] The elevator guide rail straightening device in the aforementioned patent has the following shortcomings: Although the device eliminates the need for manual repetitive inspection and straightening of the guide rail, making it easy to operate and greatly reducing the labor intensity of workers, it still requires observation of the bent parts during use in order to perform targeted straightening, which makes the straightening process relatively inconvenient. Furthermore, it cannot straighten both ends of the guide rail simultaneously, thus increasing the complexity of the straightening process. Therefore, the convenience and work efficiency of this device during straightening can be further improved. Utility Model Content

[0005] To improve work efficiency and convenience during correction, this application provides a correction device for elevator guide rails.

[0006] The present application provides an elevator guide rail straightening device with the following technical solution: an elevator guide rail straightening device includes a workbench, with corresponding support feet fixedly installed around the bottom of the workbench, a guide rail placed vertically on the top of the workbench, and a straightening mechanism for processing the guide rail on the top of the workbench. The correction mechanism includes a housing fixedly installed at the bottom of the workbench. A screw with a bidirectional thread is rotatably installed inside the housing. Two threaded blocks are symmetrically screwed onto the screw. A corresponding connecting rod is fixedly installed on the top of each of the two threaded blocks. A corresponding correction plate is fixedly installed on the top of each of the two connecting rods. A sliding groove is provided on the top of the workbench. The two connecting rods are slidably installed in the sliding groove. A fixing frame is fixedly installed on one side of the housing. A motor is fixedly installed on the fixing frame. The output end of the motor is fixedly installed to one end of the screw.

[0007] By adopting the above technical solution, the motor is controlled to start, and the output of the motor drives the screw to rotate. The rotation of the screw causes the two threaded blocks and the two connecting rods to move closer to each other. The two connecting rods move closer to each other, causing the two straightening plates to move closer to each other as well, thus straightening the guide rail. The simultaneous action of the two straightening plates makes the force distribution on the guide rail more balanced, effectively dispersing pressure and avoiding local deformation or stress concentration. This allows for the overall straightening of the guide rail, thereby further improving the convenience and efficiency of the straightening process.

[0008] Preferably, two support plates are symmetrically fixedly installed on the top of the workbench. Each of the two support plates is fixedly installed with a corresponding sleeve. Each of the two sleeves is slidably installed with a corresponding sliding rod. One end of each of the two sliding rods is fixedly installed with a corresponding positioning plate. Each of the two sleeves is screwed with a corresponding positioning bolt.

[0009] By adopting the above technical solution, by pulling the two positioning plates closer to each other, the corresponding sliding rod will also move, thereby initially positioning and installing the guide rail. Then, by rotating the positioning bolts, the positioning and installation of the sliding rod and positioning plate can be completed.

[0010] Preferably, each of the two positioning plates has a corresponding mounting groove on the side that is close to each other, and each of the two mounting grooves has a corresponding rubber plate.

[0011] By adopting the above technical solution, when the two ends of the guide rail are corrected, deformation may occur, which will squeeze the rubber plate and prevent the guide rail from directly contacting the positioning plate, thus preventing motion interference.

[0012] Preferably, corresponding top frames are fixedly installed on both sides of the workbench, and corresponding boxes are fixedly installed on both top frames. Each of the two boxes has a corresponding T-shaped groove, and a corresponding T-shaped block is slidably installed in each of the two T-shaped grooves.

[0013] By adopting the above technical solution, T-slots and T-blocks can be set up to assist in the installation.

[0014] Preferably, the length of the two T-slots is greater than the length of the two T-blocks.

[0015] By adopting the above technical solution, the length of the T-slot must be greater than the length of the T-block, thus facilitating the movement of the T-block.

[0016] Preferably, each of the two T-shaped blocks has a corresponding electric telescopic rod fixedly installed at its bottom, and each of the two electric telescopic rods has a corresponding electromagnet fixedly installed at its output end. The outer surface of the fixed end of each of the two electric telescopic rods is connected to the same synchronization plate.

[0017] By adopting the above technical solution, the synchronous plate is moved, which in turn moves the two electric telescopic rods to the top of the guide rail. At this time, the electric telescopic rods are activated and the electromagnets are pushed to contact the guide rails and attract them, which facilitates the movement of the guide rails and the unloading of materials. Therefore, the convenience and flexibility of the correction process can be further improved.

[0018] Preferably, the bottom of the workbench is provided with a control panel, and the control panel is connected to the motor, electric telescopic rod and electromagnet for signal connection.

[0019] By adopting the above technical solution, the opening and closing of the motor, electric telescopic pole, and electromagnet can be controlled by setting up a control panel.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This application employs a straightening plate and the like. By controlling the start-up motor, the output end of the motor drives the screw to rotate. The rotation of the screw causes two threaded blocks and two connecting rods to move closer together. The two connecting rods moving closer together cause the two straightening plates to move closer together as well, thus straightening the guide rail. Furthermore, the simultaneous action of the two straightening plates makes the force distribution on the guide rail more balanced, effectively dispersing pressure and avoiding local deformation or stress concentration. This allows for the overall straightening of the guide rail, thereby further improving the convenience and efficiency of the straightening process.

[0021] 2. This application employs a synchronous plate and the like. By pulling the synchronous plate, two electric telescopic rods are moved along with it and moved above the guide rail. At this point, the electric telescopic rods are activated, which pushes the electromagnets to contact the guide rail and attract them. This facilitates the movement of the guide rail and the unloading of materials from the guide rail, thus further improving the convenience and flexibility during correction.

[0023] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0024] This application discloses a correction device for elevator guide rails.

[0025] Reference Figure 1-3 A straightening device for elevator guide rails includes a workbench 1, with corresponding support feet 2 fixedly installed around the bottom of the workbench 1, and a guide rail 4 placed vertically on the top of the workbench 1. A straightening mechanism, a positioning mechanism, and a feeding mechanism are set on the top of the workbench 1 for processing the guide rail 4. The correction mechanism includes a housing 12 fixedly installed at the bottom of the workbench 1. A screw 14 is rotatably installed inside the housing 12, and the screw 14 has a bidirectional thread. Two threaded blocks 15 are symmetrically screwed onto the screw 14. A corresponding connecting rod 13 is fixedly installed on the top of each of the two threaded blocks 15. A corresponding correction plate 9 is fixedly installed on the top of each of the two connecting rods 13. A sliding groove 10 is opened on the top of the workbench 1, and the two connecting rods 13 are slidably installed in the sliding groove 10. A fixing frame 16 is fixedly installed on one side of the housing 12, and a motor 17 is fixedly installed on the fixing frame 16. The output end of the motor 17 is fixedly installed to one end of the screw 14.

[0026] In use, by controlling the start motor 17, the output end of the motor 17 will drive the screw 14 to rotate. The rotation of the screw 14 will drive the two threaded blocks 15 and the two connecting rods 13 to move closer to each other. The two connecting rods 13 will move closer to each other and drive the two straightening plates 9 to move closer to each other as well, thus straightening the guide rail 4. With the two straightening plates 9 working simultaneously, the force distribution on the guide rail 4 can be more balanced, effectively dispersing pressure and avoiding local deformation or stress concentration. This allows for the overall straightening of the guide rail 4, thereby further improving the convenience and efficiency of the straightening process.

[0027] Reference Figure 2-3The positioning mechanism includes two support plates 5 symmetrically fixedly installed on the top of the workbench 1. Each of the two support plates 5 is fixedly installed with a corresponding sleeve 6. Each of the two sleeves 6 is slidably installed with a corresponding sliding rod 7. Each of the two sliding rods 7 is fixedly installed with a corresponding positioning plate 3 at one end. Each of the two sleeves 6 is screwed with a corresponding positioning bolt 8. Each of the two positioning plates 3 has a corresponding mounting groove 25 on the side that is close to each other. Each of the two mounting grooves 25 is provided with a corresponding rubber plate 26.

[0028] In use, by pulling the two positioning plates 3 closer together, the corresponding sliding rod 7 will also move, thus allowing the guide rail 4 to be initially positioned and installed. Then, by rotating the positioning bolt 8, the sliding rod 7 and the positioning plate 3 can be positioned and installed.

[0029] Reference Figure 1 and Figure 4 The unloading mechanism includes top frames 18 fixedly installed on both sides of the workbench 1. Each top frame 18 is fixedly installed with a corresponding box 19. Each box 19 has a corresponding T-shaped groove 20. Each T-shaped groove 20 has a corresponding T-shaped block 21 slidably installed in it. The length of each T-shaped groove 20 is greater than the length of each T-shaped block 21. Each T-shaped block 21 has a corresponding electric telescopic rod 22 fixedly installed at its bottom. Each electric telescopic rod 22 has a corresponding electromagnet 23 fixedly installed at its output end. The outer surface of the fixed end of each electric telescopic rod 22 is connected to the same synchronous plate 24. The bottom of the workbench 1 is equipped with a control panel 11. The control panel 11 is connected to the motor 17, the electric telescopic rod 22 and the electromagnet 23 by signal connection. The control panel 11, motor 17 and electric telescopic rod 22 in this application are all existing technology products, so the specific models and connection and usage process are not described in detail.

[0030] In use, the synchronous plate 24 is pulled to move, which will drive the two electric telescopic rods 22 to move as well, and move them above the guide rail 4. At this time, the electric telescopic rods 22 are activated and will push the electromagnet 23 to contact the guide rail 4 and attract it, which facilitates the movement of the guide rail 4 and the feeding of materials to the guide rail 4. Therefore, the convenience and flexibility of the correction can be further improved.

[0031] The implementation principle of the elevator guide rail straightening device in this application embodiment is as follows: When in use, the guide rail 4 is first placed and installed on the workbench 1 in a vertical state. At this time, the two positioning plates 3 can be pulled closer to each other, which will also drive the corresponding sliding rod 7 to move. Thus, the guide rail 4 can be initially positioned and installed. Then, by rotating the positioning bolt 8, the positioning and installation of the sliding rod 7 and the positioning plate 3 can be completed. At this time, by controlling the start motor 17, the output end of the motor 17 will drive the screw 14 to rotate. The rotation of the screw 14 will drive the two threaded blocks 15 and the two connecting rods 13 to move closer to each other. The two connecting rods 13 will move closer to each other and drive the two straightening plates 9 to move closer to each other as well, thus straightening the guide rail 4. With the two straightening plates 9 working simultaneously, the force distribution on the guide rail 4 can be more balanced, effectively dispersing pressure and avoiding local deformation or stress concentration. This allows for the overall straightening of the guide rail 4, thereby further improving the convenience and efficiency of the straightening process. When the two ends of the guide rail 4 are straightened, deformation may occur, which will squeeze the rubber plate 26 and prevent the guide rail 4 from directly contacting the positioning plate 3, and prevent motion interference. By using it in conjunction with external level and other equipment, the parallelism of guide rail 4 can be detected, which makes it easier to control the accuracy of guide rail 4 during correction. By pulling the synchronous plate 24, the two electric telescopic rods 22 will also move and move to the top of the guide rail 4. At this time, the electric telescopic rods 22 are activated and the electromagnet 23 is pushed to contact the guide rail 4 and be attracted to it, which facilitates the movement of the guide rail 4 and the feeding of the guide rail 4. Therefore, the convenience and flexibility of the correction can be further improved.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
