Description

Technical Field

[0001] This utility model relates to the field of elevator door installation technology, and in particular to a rapid calibration and positioning component for elevator door operator maintenance. Background Technology

[0002] As an indispensable vertical transportation tool in modern high-rise buildings, the safety, stability, and comfort of elevators directly affect users' lives, property, and experience. The elevator door system is the component where passengers interact most frequently and directly, making its operational status particularly critical. The leveling accuracy, opening and closing speed, synchronization, and door lock engagement reliability of the elevator doors all depend on the precision of the door operator system and its installation and positioning.

[0003] Traditional calibration work typically involves maintenance personnel using basic tools such as measuring tapes, levels, and feeler gauges to repeatedly measure and manually adjust the positions of components like the door operator's mounting plate, door slider, and door knife. This process is not only time-consuming and labor-intensive but also heavily reliant on the individual experience and skill level of the maintenance personnel. Different operating habits and judgment standards among personnel can lead to significant differences in calibration results, making it difficult to guarantee standardization and consistency. This is especially true in environments with insufficient lighting or confined spaces, where work efficiency is greatly reduced. During subsequent tightening or fine-tuning, the door panel is prone to slight displacement, resulting in a loss of calibration accuracy. This "one-off" positioning method cannot provide continuous and stable clamping force during installation, making it difficult to meet the stringent millimeter-level installation accuracy requirements of modern elevators. During calibration, if the clamping tools are poorly designed, their sharp edges or excessive clamping force may cause secondary damage such as scratches and indentations on the door panel surface, affecting aesthetics or even damaging the door panel structure. Furthermore, if the temporary fixing support device is unreliable, there is a risk of the door panel accidentally slipping, posing a safety threat to on-site personnel and equipment.

[0004] To address the above issues, a rapid calibration and positioning component for elevator door operator maintenance needs to be designed to overcome these problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a rapid calibration and positioning component for elevator door operator maintenance, which can effectively solve the problems in the background art.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-4 As shown, a rapid calibration and positioning component for elevator door operator maintenance includes a base 1, an adjustment groove 2, and a positioning frame 3. The positioning calibration component is installed inside the adjustment groove 2.

[0025] The positioning calibration assembly includes a rounded corner limiting arm 4 set inside one end of the adjustment groove 2. A rotating rod 5 is connected to the top of the rounded corner limiting arm 4. A trapezoidal positioning block 6 is sleeved on the outer wall of the rotating rod 5. An L-shaped limiting plate 8 is connected to the top of the trapezoidal positioning block 6 through the top of the rotating rod 5. An elastic pad 7 is provided on one side of the trapezoidal positioning block 6. A protective pad 9 is provided on one side of the L-shaped limiting plate 8. A snap-fit ​​hole 15 is opened at one end of the trapezoidal positioning block 6. A positioning plate 10 is installed at one end of the inner side of the positioning frame 3. A limiting cylinder 11 is installed on one side of the positioning plate 10. A telescopic rod 12 is connected to the inner side of the limiting cylinder 11. A spring 13 is provided on the outer wall of the telescopic rod 12. A snap-fit ​​ball 14 is installed at the end of the telescopic rod 12 away from the limiting cylinder 11.

[0026] The rounded corner limiting arm 4 is slidably connected to the inner side of the adjusting groove 2 via an adjusting slider. The rounded corner limiting arm 4 is rotatably connected to the rotating rod 5, and the rotating rod 5 is rotatably connected to the trapezoidal positioning block 6. The trapezoidal positioning block 6 and the L-shaped limiting plate 8 are fixedly connected to the elastic pad 7 and the protective pad 9, respectively. The snap-fit ​​ball 14 snaps into the snap-fit ​​hole 15. The positioning plate 10 is rotatably connected to the limiting cylinder 11. The limiting cylinder 11 is rotatably connected to the telescopic rod 12. The telescopic rod 12 is fixedly connected to the spring 13. The telescopic rod 12 is fixedly connected to the snap-fit ​​ball 14.

[0027] Specifically, in this embodiment, the base 1 serves as the mounting foundation for the entire component and is typically made of high-strength metal material. Its bottom is designed with a flat mounting surface, which can be securely fixed to the reference structure of the elevator car top or door frame by means of bolts or magnetic chucks. On the upper surface of the base 1, one or more parallel adjustment grooves 2 are opened in the horizontal direction. The groove provides precise linear guidance for subsequent sliding adjustment. At one end of the base 1, a positioning frame 3 is vertically fixed and installed. The internal space of the frame is used to accommodate and install the core positioning and locking mechanism.

[0028] A slider is installed at the lower end of the rounded corner limiting arm 4. The slider matches the cross-sectional shape of the adjustment groove 2, so that the rounded corner limiting arm 4 can slide smoothly along the length of the adjustment groove 2. In order to achieve dual limiting and guidance, a rounded corner limiting slider 16 is fixedly connected to the end of the rounded corner limiting arm 4 away from the rotating rod 5 by a mounting rod. Correspondingly, a rounded corner limiting groove 17 is opened on the inner side of the positioning frame 3, which perfectly matches the movement trajectory of the rounded corner limiting slider 16. When the rounded corner limiting arm 4 moves, the rounded corner limiting slider 16 slides synchronously in the rounded corner limiting groove 17, which improves the stability and anti-swaying ability of the sliding process and ensures that the positioning calibration component will not tilt during coarse adjustment.

[0029] The trapezoidal positioning block 6 and the L-shaped limiting plate 8 are key components that directly contact the elevator door panel and perform the clamping function. The trapezoidal positioning block 6 has a through hole in the center and is sleeved on the outer wall of the rotating rod 5, forming a rotatable connection with the rotating rod 5. The L-shaped limiting plate 8 is fixedly installed on the top of the trapezoidal positioning block 6 and fixedly connected to the top of the rotating rod 5, ensuring that when the operator rotates the rotating rod 5, the trapezoidal positioning block 6 and the L-shaped limiting plate 8 will swing synchronously and in linkage around the rotating rod 5 as the axis.

[0030] To protect the elevator door panel surface during clamping and prevent scratches or indentations, an elastic pad 7 is installed on the side of the trapezoidal positioning block 6 that contacts the door panel, by means of adhesive or screw fixing. Similarly, a protective pad 9 is also installed on the surface of the L-shaped limiting plate 8 that contacts the door panel. Both the elastic pad 7 and the protective pad 9 are made of non-metallic materials with high elasticity, high coefficient of friction and soft texture, such as polyurethane rubber and nitrile rubber.

[0031] A positioning plate 10 is fixedly installed at a predetermined position on the inner side of the positioning frame 3 by screws. A limiting cylinder 11 is installed on the positioning plate 10, and the axis of the limiting cylinder 11 is tangent to the movement trajectory of the trapezoidal positioning block 6 when it rotates. A telescopic rod 12 is slidably connected inside the limiting cylinder 11. A spring 13 is provided between the end of the telescopic rod 12 near the positioning plate 10 and the bottom of the limiting cylinder 11. The spring 13 is always in a compressed state, providing an outward thrust to the telescopic rod 12. A locking ball 14, usually a steel ball, is fixedly installed at the end of the telescopic rod 12 away from the spring 13. Correspondingly, on the side of the trapezoidal positioning block 6, when it rotates to the predetermined clamping position, a locking hole 15 matching the diameter of the locking ball 14 is opened directly opposite the locking ball 14. When the trapezoidal positioning block 6 rotates into place, the locking ball 14 can be accurately embedded into the locking hole 15 under the elastic force of the spring 13, achieving reliable locking and fixing.

[0032] The end of the rounded corner limiting arm 4 away from the rotating rod 5 is connected to the rounded corner limiting slider 16 via the mounting rod. The inner side of the positioning frame 3 is provided with a rounded corner limiting groove 17 at the end near the rounded corner limiting slider 16. The outer wall of the rotating rod 5 is fitted with a movable bushing 18 at the end near the rounded corner limiting arm 4. A support arm 19 is installed at one end of the movable bushing 18. A battery 20 is installed on the outer wall of the support arm 19. Multiple lights 21 are provided at the end of the battery 20 away from the support arm 19.

[0033] The rounded corner limiting slider 16 is fixedly connected to the rounded corner limiting arm 4 via the mounting rod, and the rounded corner limiting slider 16 is slidably connected to the inner side of the rounded corner limiting groove 17; the movable bushing 18 is movably connected to the inner side of the rounded corner limiting arm 4 via the rotating rod 5, and the movable bushing 18 is fixedly connected to the support arm 19. The support arm 19 is fixedly connected to the battery 20, and the battery 20 is electrically connected to the lighting lamp 21.

[0034] Specifically, in this embodiment, a movable bushing 18 is fitted on the outer wall of the rotating rod 5, between the rounded corner limiting arm 4 and the trapezoidal positioning block 6. This movable bushing 18 can rotate freely around the rotating rod 5, and its angle can be locked when needed by means of a set screw. A support arm 19 is fixedly connected to one end of the movable bushing 18. Maintenance personnel can manually adjust the angle of the support arm 19 according to the site space and support requirements, so that its end can reliably abut against a stable structure such as the car wall or column, providing additional rigid support for the entire clamping unit. A battery 20 is installed on the outer wall of the support arm 19 to power the lighting equipment. One or more lighting lamps 21, such as LED beads, are installed at the end of the support arm 19 away from the movable bushing 18. The battery 20 and the lighting lamps 21 are electrically connected by wires and are equipped with independent switches. In this way, the lighting lamps 21 can be turned on at any time during calibration work to provide sufficient and concentrated lighting for the operating area.

[0035] It should be noted that this utility model is a quick calibration and positioning component for elevator door operator maintenance. In use, the elevator door panel to be installed is placed in the open space between the trapezoidal positioning block 6 and the L-shaped limiting plate 8. Personnel operate the rotating rod 5 to rotate it around its own axis. Since the rotating rod 5 is the common rotation axis of the trapezoidal positioning block 6 and the L-shaped limiting plate 8, its rotation will directly drive the two components to make synchronous and linked angle changes. As the rotating rod 5 rotates, the trapezoidal positioning block 6, which can be regarded as the main clamping arm, will swing, so that the side with the elastic pad 7 installed will gradually contact and press against one side of the elevator door. At the same time, the L-shaped limiting plate 8, which can be regarded as the secondary clamping arm, which is fixedly connected to the trapezoidal positioning block 6, will also swing, so that the side with the protective pad 9 installed will gradually contact and press against the other side adjacent to this side, which is usually the top or bottom surface of the door panel. When the rotating rod 5 drives the trapezoidal positioning block 6 to rotate to the predetermined clamping angle, the snap-fit ​​hole 15 on the side of the trapezoidal positioning block 6 will align with the snap-fit ​​ball 14 installed on the positioning frame 3. During rotation, the sidewall of the trapezoidal positioning block 6 first squeezes the locking ball 14, compressing the internal spring 13. Once aligned, the spring 13 immediately releases energy, pushing the locking ball 14 into the locking hole 15 with a "click" sound, achieving a quick and secure angle lock. During rotation, the movable bushing 18 and support arm 19, fitted onto the rotating rod 5, can be manually adjusted to an optimal support angle, resting against the surrounding structure to provide additional rigid support for the entire assembly, further enhancing the overall stability of the system. This also facilitates maintenance in low-light shaft environments. Personnel can turn on the lighting 21 powered by the storage battery 20. The light shines directly on the door panel installation area, ensuring that the operator can clearly see the bolt holes, positioning marks, etc., improving the accuracy and efficiency of the operation. After all the installation work is completed, simply rotate the rotating rod 5 in the opposite direction, and the locking ball 14 will slide out from the locking hole 15, compressing the spring 13, thereby unlocking the positioning. Continue to rotate the rotating rod 5 in the opposite direction, and the trapezoidal positioning block 6 and the L-shaped limit plate 8 will release the door panel simultaneously. Finally, slide the rounded corner limit arm 4 back along the adjustment groove 2, and the entire component can be easily removed.
