Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator installation technology, specifically to a rapid calibration device for elevator guide rails. Background Technology
[0002] Elevator guide rails are the core safety components of an elevator system. Installed in the elevator shaft or between floors, they form a vertical or inclined rigid track. The main cross-sectional shapes are T-shaped, L-shaped, and hollow. Elevator guide rails provide guidance for the vertical or inclined movement of the car, ensuring that it runs along a predetermined trajectory. They also withstand the loads and impacts during operation. Precise clearance control ensures smooth sliding between the guide shoes and the guide rails, preventing jamming or disengagement. During the installation of elevator guide rails, it is necessary to ensure that the guide rails are firmly fixed to the shaft wall and are vertical.
[0003] In existing technology, a connecting plate is fixedly connected to the guide rail, and a support plate connected to the connecting plate is fixed to the inner wall of the elevator shaft. The support plate supports the connecting plate connected to the guide rail. When the elevator is under maintenance, the guide rail will bend after long-term use. When adjusting the verticality of the guide rail, a calibration caliper is clamped on the guide rail, and the verticality of the guide rail is determined by plumb bob. The tilt of the guide rail is adjusted by workers tapping the connecting plate with tools. However, during the calibration process, because the guide rail is long, people need to frequently install and remove the caliper, which is quite cumbersome. Utility Model Content
[0004] The purpose of this invention is to provide a rapid calibration device for elevator guide rails to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid calibration device for elevator guide rails, comprising a guide rail and a calibration frame. The calibration frame is slidably locked on the outside of the guide rail. Rotating rods are symmetrically and rotatably mounted on both sides of the calibration frame. A locking block is fixedly mounted at one end of each rotating rod. The two sides of the guide rail are locked between the locking block and the calibration frame. Connecting rods are fixedly mounted at the bottom of the calibration frame. Fixing plates are fixedly mounted at the bottom ends of the two connecting rods. A pressing rod is elastically and slidably mounted on the surface of the fixing plate. One end of the pressing rod is in pressing contact with the two sides of the guide rail. A triangular block is fixedly mounted at the other end of the pressing rod. A groove is provided on the surface of the fixing plate corresponding to the position of the triangular block.
[0006] As a further preferred embodiment of this technical solution, a rotating block is fixedly installed at the end of the rotating rod away from the locking block, and a storage slot is symmetrically opened on the top of the calibration frame, with the rotating block slidingly locked inside the storage slot.
[0007] As a further preferred embodiment of this technical solution, a positioning plate is symmetrically mounted on the top of the calibration rack via a pivot pin, and the positioning plate can seal the top of the storage slot.
[0008] As a further preferred embodiment of this technical solution, a first mounting block is fixedly installed on the surface of the fixing plate, the extrusion rod is slidably installed inside the first mounting block, a compression spring is sleeved on the outer side of one end of the extrusion rod, one end of the compression spring is fixedly connected to one side of the first mounting block, and the other end of the compression spring is fixedly connected to the outer wall of the extrusion rod, and the compression spring is continuously in a compressed state.
[0009] As a further preferred embodiment of this technical solution, a second mounting block is fixedly installed on the upper surface of the calibration frame, and a movable rod is slidably installed inside the second mounting block. A pressing block is fixedly installed at one end of the movable rod, and the pressing block is in pressing contact with both sides of the guide rail.

[0011] As a further preferred embodiment of this technical solution, a pull ring is fixedly installed at the end of the extrusion block away from the movable rod.
[0012] This utility model provides a rapid calibration device for elevator guide rails, which has the following beneficial effects:
[0013] (1) This utility model uses the two sides of the guide rail to be clamped between the clamping block and the calibration frame. The device is in a whole fit with the installation position of the guide rail. When the guide rail is bent, since the extrusion block is always pressing against the two sides of the guide rail, the triangular block at the end of the extrusion rod is in the positive and negative position of the groove. By tapping the connecting frame connected to the guide rail to slide on the support frame, the guide rail can be controlled to return to the vertical state. Then, the connecting frame connected to the guide rail and the support frame are welded together to fix the calibration position. When the guide rail is in the vertical state, when one end of the extrusion block presses against the two sides of the guide rail, the triangular block at the end of the extrusion rod is in the zero point position of the groove. The guide rail at this position is in the vertical state, which is easy to operate.
[0014] (2) After calibrating a section of the guide rail, the calibration frame is slid down to the next section of the guide rail by sliding along the outside of the guide rail. This eliminates the need for frequent installation and removal of the calibration frame, making it convenient to use. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, an elevator guide rail rapid calibration device includes a guide rail 1 and a calibration frame 2. The calibration frame 2 is slidably locked onto the outside of the guide rail 1. Rotating rods 3 are symmetrically mounted on both sides of the calibration frame 2. A locking block 4 is fixedly mounted at one end of each rotating rod 3. The two sides of the guide rail 1 are locked between the locking block 4 and the calibration frame 2. Connecting rods 5 are fixedly mounted at the bottom of the calibration frame 2. Fixing plates 6 are fixedly mounted at the bottom ends of the two connecting rods 5. A pressing rod 7 is elastically slidably mounted on the surface of the fixing plate 6. One end of the pressing rod 7 is in pressing contact with the two sides of the guide rail 1, and a triangular block 8 is fixedly mounted at the other end. A groove 9 is provided on the surface of the fixing plate 6 corresponding to the position of the triangular block 8. The middle of the groove 9 is the zero point, and the two ends are the positive and negative ends. By sliding the calibration frame 2 onto the outside of the guide rail 1 and locking the two sides of the guide rail 1 between the locking block 4 and the calibration frame 2, the device is integrally fitted relative to the installation position of the guide rail 1. When the guide rail 1 bends, since the pressing block 17 is always pressing against both sides of the guide rail 1, the triangular block 8 at the end of the pressing rod 7 is in the positive and negative positions of the groove 9. By tapping the connecting frame connected to the guide rail 1 and sliding it on the support frame, the guide rail 1 can be controlled to return to a vertical state. Then, the connecting frame connected to the guide rail 1 and the support frame are welded together to fix the calibration position. When the guide rail 1 is in a vertical state, when one end of the pressing block 17 presses against both sides of the guide rail 1, the triangular block 8 at the end of the pressing rod 7 is in the zero point position of the groove 9. This position confirms that the guide rail 1 is in a vertical state. After calibrating a section of the guide rail 1, the calibration frame 2 is pushed down to the next section of the guide rail 1 by sliding along the outside of the guide rail 1. The same operation steps are used to calibrate the entire guide rail 1 by bending. This makes it convenient to calibrate the entire guide rail 1 by bending, without the need for frequent installation and removal of the calibration frame 2. The operation is simple.
[0022] like Figures 1 to 4 As shown, a rotating block 10 is fixedly installed at the end of the rotating rod 3 away from the locking block 4. A storage slot 11 is symmetrically opened on the top of the calibration frame 2. The rotating block 10 is slidably locked inside the storage slot 11. A positioning plate 12 is symmetrically rotated on the top of the calibration frame 2 through a pivot pin. The positioning plate 12 can close the top of the storage slot 11.
[0023] The calibration frame 2 is slidably clipped onto the outside of the guide rail 1. Then, the rotating block 10 at the end of the rotating rod 3 is rotated so that the locking block 4 at one end of the rotating rod 3 is rotated to the rear of both sides of the guide rail 1. At this time, the rotating block 10 is stored inside the storage slot 11. Then, the positioning plate 12 is rotated so that the positioning plate 12 can position the top of the rotating block 10, thereby fixing the position of the locking block 4.
[0024] like Figures 1 to 4As shown, a first mounting block 13 is fixedly installed on the surface of the fixing plate 6, and the extrusion rod 7 is slidably installed inside the first mounting block 13. A compression spring 14 is sleeved on the outer side of one end of the extrusion rod 7. One end of the compression spring 14 is fixedly connected to one side of the first mounting block 13, and the other end of the compression spring 14 is fixedly connected to the outer wall of the extrusion rod 7. The compression spring 14 is continuously in a compressed state.
[0025] When the calibration frame 2 is slidably locked on the outside of the guide rail 1, the compression spring 14 pushes one end of the extrusion rod 7, causing the end of the extrusion rod 7 to continuously contact one side surface of the extrusion guide rail 1, which is used to determine the position of the triangular block 8 at the end of the extrusion rod 7 relative to the groove 9.
[0026] like Figures 1 to 4 As shown, a second mounting block 15 is fixedly installed on the upper surface of the calibration frame 2. A movable rod 16 is slidably installed inside the second mounting block 15. A pressing block 17 is fixedly installed at one end of the movable rod 16. The pressing block 17 is in pressing contact with the two side surfaces of the guide rail 1. A stretching spring 18 is sleeved on the outer side of one end of the movable rod 16. One end of the stretching spring 18 is fixedly connected to one side of the second mounting block 15, and the other end of the stretching spring 18 is fixedly connected to the outer wall of the movable rod 16. The stretching spring 18 is continuously in a stretched state. A rubber friction pad 19 is fixedly installed at the end of the movable rod 16 away from the pressing block 17. A pull ring 20 is fixedly installed at the end of the pressing block 17 away from the movable rod 16.
[0027] The two sides of the guide rail 1 are locked between the locking block 4 and the calibration frame 2. The pulling of the movable rod 16 by the extension spring 18 will cause the pressing block 17 to press against the two sides of the guide rail 1, which is used to fix the calibration frame 2 on the guide rail 1 and prevent relative movement between the guide rail 1 and the calibration frame 2.
[0028] This utility model provides a rapid calibration device for elevator guide rails, the specific working principle of which is as follows:
[0029] When using the device, the calibration frame 2 is slidably locked onto the outside of the guide rail 1. Then, the rotating block 10 at the end of the rotating rod 3 is rotated, and the locking block 4 at one end of the rotating rod 3 is rotated to the rear of both sides of the guide rail 1, locking both sides of the guide rail 1 between the locking block 4 and the calibration frame 2. The pulling of the movable rod 16 by the extension spring 18 will cause the pressing block 17 to press against the two sides of the guide rail 1, which is used to fix the calibration frame 2 on the guide rail 1. The device is integrally fitted with the guide rail 1 at this installation position. At the same time, the pushing of one end of the pressing rod 7 by the compression spring 14 will cause the end of the pressing rod 7 to press against one side of the guide rail 1. When the guide rail 1 bends, since the pressing block 17 is always pressing against the two sides of the guide rail 1, the triangular block 8 at the end of the pressing rod 7 is in the positive and negative position of the groove 9. The guide rail 1 is positioned so that it can be controlled to return to a vertical state by tapping the connecting bracket connected to the guide rail 1 and sliding it on the support frame. Then, the connecting bracket connected to the guide rail 1 is welded to the support frame to fix the calibration position. When the guide rail 1 is in a vertical state, when one end of the pressing block 17 presses against the two sides of the guide rail 1, the triangular block 8 at the end of the pressing rod 7 is at the zero point of the groove 9, confirming that the guide rail 1 is in a vertical state at this position. After calibrating a section of the guide rail 1, the pull ring 20 at one end of the movable rod 16 is pulled to cancel the pressing friction of the pressing block 17 on the two sides of the guide rail 1. The calibration frame 2 is then pushed down to the next section of the guide rail 1 by sliding along the outside of the guide rail 1. The same operation steps are used to bend and calibrate the entire guide rail 1.
