[0001] This utility model relates to the technical field of elevator guide rail calibration devices, and in particular to an elevator guide rail calibration device. Background Technology
[0002] The elevator guide rail calibration device is mainly used for the installation, calibration, and operation debugging of elevator guide rails. With the help of measurement and sensing modules, stable and reliable adjustment and execution components, and positioning units that are compatible with multiple guide rail specifications, coupled with a stable support structure that resists vibration interference and a fast-response calibration feedback mechanism, it can achieve high-precision calibration and stable fixation of guide rails in scenarios such as verticality correction, precise spacing adjustment, and smooth operation debugging during elevator guide rail installation. It is suitable for elevator guide rail installation and debugging operations in complex environments with high requirements for guide rail installation accuracy, such as high-rise buildings and heavy-duty elevators.
[0003] Existing elevator guide rail calibration devices sometimes fail to adapt to different guide rail specifications, requiring operators to replace the entire calibration device when faced with diverse guide rail calibration needs. This increases equipment procurement costs and is time-consuming, reducing overall efficiency. Therefore, a new elevator guide rail calibration device is proposed to solve these problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an elevator guide rail calibration device, which aims to improve the problem that some existing devices cannot adapt to guide rails of different specifications.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A guide device for calibrating elevator guide rails includes a limiting block, a clamping block fixedly connected to the right end of the limiting block, a fixed plate slidably connected inside the limiting block, a telescopic column fixedly connected inside the fixed plate, a fixed column fixedly connected to the left end of the telescopic column, a sliding block fixedly connected to the left end of the fixed column, a spring sleeved on the outside of the telescopic column, and a graduated outer column fixedly connected to the rear end of the fixed plate, with a measuring component inside the graduated outer column.
[0007] As a further description of the above technical solution: the measuring component includes a scale inner column, the front end of which is slidably connected to the inside of the scale outer column, and a telescopic column two is fixedly connected to the front end of the scale inner column, and a spring two is sleeved on the outside of the telescopic column two.
[0008] As a further description of the above technical solution: the clamping block is internally threaded with a stud, and a magnet is fixedly connected to the rear end of the stud.
[0009] As a further description of the above technical solution: the clamping block has a track inside, and the rear end of the magnet is in contact with the outside of the track.
[0010] As a further description of the above technical solution: the rear end of the clamping block is threaded with a stud II, and the bottom end of the stud II is threaded with a scale plate.
[0011] As a further description of the above technical solution: one end of the spring is fixedly connected to the right end of the fixed column, and the other end of the spring is fixedly connected to the inside of the limiting block.
[0012] As a further description of the above technical solution: one end of the second spring is fixedly connected to the front end of the inner column of the scale, and the other end of the second spring is fixedly connected to the inside of the outer column of the scale.
[0013] As a further description of the above technical solution: the sliding block has an oblique shape, and the outside of the sliding block is slidably connected to the inside of the limiting block.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model allows the magnet to be moved to a designated position by rotating a stud, dragging the clamping block outside the track, and then rotating the stud in the opposite direction to make it press against the track and fix it. Data is read through the scale bar on the outside of the clamping block. When the clamping block needs to be replaced, the sliding block is pressed to slide into the limiting block, the telescopic column moves to the right to compress the spring, and the limiting block is dragged to release the restriction of the fixing plate. The new limiting block is slid into the fixing plate. After reaching the designated position, the compressed spring pushes the fixing column in the opposite direction, causing the sliding block to slide out of the limiting block, and the fixing plate restricts its position. By replacing the limiting block, it can be adapted to guide rails of different specifications without replacing the device, thus reducing costs.
[0016] 2. This utility model fixes the clamping block and the track at a designated position. When the distance between the two guide rails is different, the inner column of the scale will slide into the outer column of the scale, causing the telescopic column two to move backward and compress the spring two. The operator can adjust the guide rail accordingly based on the reading of the outer scale of the inner column of the scale. After the measurement is completed, the clamping block and the track are released from fixation. The compressed spring two pushes the inner column of the scale back to reset, ready for the next measurement. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 , Figure 6 and Figure 7 This utility model provides an embodiment of an elevator guide rail calibration device, including a limiting block 1 with scale markings on its exterior, allowing the operator to read data based on the scales. The limiting block 1 also provides a fixed mounting base for a clamping block 2. The right end of the limiting block 1 is fixedly connected to the clamping block 2, which clamps and fixes the track 14, providing a stable foundation for calibration and measurement. The clamping block 2 has a threaded connection to a stud 12, whose rotation controls the position of a magnet 13, thus fixing and releasing the track 14. The rear end of the stud 12 is fixedly connected to a magnet 13, which attracts the track 14, improving stability during fixing. The rear end of the clamping block 2 is threadedly connected to a second stud 15, which drives a scale plate 16 for position adjustment, ensuring the measurement reference of the scale plate 16. The bottom end of the second stud 15 is threadedly connected to a scale plate 16, which assists the operator in reading the relative specification data of the track 14.
[0028] Reference Figures 1 to 3 The limiting block 1 has a sliding connection to a fixed plate 3. The limiting block 1 provides a track for the installation and sliding of the fixed plate 3, enabling quick replacement of the limiting block 1. The fixed plate 3 has a fixed connection to a telescopic column 4. The telescopic column 4 can extend and retract with the movement of the sliding block 6, ensuring the stability of the movement of the fixed column 5. The left end of the telescopic column 4 is fixedly connected to a fixed column 5, which connects the telescopic column 4 and the sliding block 6 and can transmit the elastic force of the spring 7 to the sliding block 6. The left end of the fixed column 5 is fixedly connected to the sliding block 6. The sliding of the sliding block 6 can lock and unlock the limiting block 1 by the fixed plate 3. The sliding block 6 is oblique in shape, which makes it easy for the operator to press and slide it. Block 6 allows it to slide smoothly into the interior of the limiting block 1. The outside of the sliding block 6 is slidably connected to the inside of the limiting block 1. Through the slid connection, the sliding block 6 can slide stably within the limiting block 1, realizing the locking and unlocking functions. The outside of the telescopic column 4 is fitted with a spring 7. The spring 7 can accumulate elastic force after the sliding block 6 is pressed, providing power for the subsequent reset of the sliding block 6. One end of the spring 7 is fixedly connected to the right end of the fixed column 5. The spring 7 transmits the elastic force to the sliding block 6 through the fixed column 5, pushing the sliding block 6 to reset. The other end of the spring 7 is fixedly connected to the inside of the limiting block 1. By fixing the spring 7 inside the limiting block 1, the spring 7 can stably extend and retract when the telescopic column 4 moves.
[0029] Reference Figure 1 , Figure 2 and Figure 5 The rear end of the fixed plate 3 is fixedly connected to the outer scale column 8. The outer scale column 8 provides position restriction and guidance for the sliding of the inner scale column 9. The outer scale column 8 is equipped with a measuring component, which can measure the verticality and spacing changes at different positions of the guide rail, providing data support for guide rail calibration.
[0030] Reference Figure 1 , Figure 4 and Figure 5The measuring component includes an inner scale column 9, which allows the operator to slide and read corresponding data inside the outer scale column 8. The inner scale column 9 has scale markings on its exterior, allowing data to be read directly from the scale. The front end of the inner scale column 9 is slidably connected to the interior of the outer scale column 8. This sliding connection allows the inner scale column 9 to move within the outer scale column 8 to accommodate different spacing between the guide rails. A telescopic column 10 is fixedly connected to the front end of the inner scale column 9, enabling synchronous movement between the inner scale column 9 and the telescopic column 10. Spring 2 11 is sleeved on the outside of the second 10. Spring 2 11 provides power for the reset of the inner scale post 9. One end of spring 2 11 is fixedly connected to the front end of the inner scale post 9. The fixed connection between spring 2 11 and the inner scale post 9 allows spring 2 11 to extend and retract with the movement of the inner scale post 9, thereby storing or releasing elastic force. The other end of spring 2 11 is fixedly connected to the inside of the outer scale post 8. The fixed connection between spring 2 11 and the outer scale post 8 provides installation support for spring 2 11, ensuring that it can play its elastic role normally when subjected to force and push the inner scale post 9 to reset.
[0031] Working principle: When the operator uses the elevator guide rail calibration device, rotating stud 12 causes magnet 13 to move to the designated position, dragging clamping block 2 to the outside of track 14, and rotating stud 12 in the opposite direction so that stud 12 abuts against track 14 and is fixed. At this time, the corresponding data can be read according to the scale bar on the outside of clamping block 2. When it is necessary to replace other clamping blocks 2, press sliding block 6 so that sliding block 6 slides into the inside of limit block 1, telescopic column 4 moves to the right and compresses spring 7, dragging limit block 1 so that fixed plate 3 removes the restriction on the position of limit block 1, and slides the new limit block 1 into the inside of fixed plate 3. When limit block 1 slides to the designated position, the compressed spring 7 pushes fixed column 5 in the opposite direction so that sliding block 6 slides out of the inside of limit block 1, achieving the restriction on the position of limit block 1 by fixed plate 3. By replacing limit block 1, it is possible to adapt to guide rails of different specifications without replacing the entire device, reducing equipment costs.
[0032] When it is necessary to measure the verticality of the elevator guide rail at different positions, the clamping block 2 and the rail 14 are fixed at the designated position. When the distance between the two guide rails is different, the inner column 9 will slide into the interior of the outer column 8, causing the telescopic column 10 to move to the rear end and compress the spring 11. At this time, the operator can read the data according to the scale on the outside of the inner column 9 and make corresponding adjustments to the guide rail. After the measurement is completed, the clamping block 2 and the rail 14 are fixed. The compressed spring 11 pushes the inner column 9 in the opposite direction, so that the inner column 9 is reset for the next measurement.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
