Description

Technical Field

[0001] This utility model belongs to the technical field of elevator leveling devices, and in particular relates to a magnetic shielding plate bracket. Background Technology

[0002] Elevator leveling devices include leveling sensors and a magnetic shielding plate mechanism. Their main function is to ensure accurate leveling of the elevator upon arrival at a floor. Specifically, leveling refers to the movement within the leveling zone where the car sill and the landing door sill are aligned on the same plane. The magnetic shielding plate mechanism includes a magnetic shield and a mounting bracket. The magnetic shield is connected to the elevator car guide rail via a bracket, and the leveling sensor is mounted on the car. When the elevator enters the leveling zone, the magnetic shield engages with the slot of the leveling sensor in the car. The elevator control system uses this signal to determine the car's position and stops the elevator car at the leveling position. However, existing magnetic shielding plate brackets are made by bending sheet metal (…). Figure 4 The magnetic shielding plate bracket has several round holes sequentially opened at one end to fix the magnetic shielding plate, resulting in a small lateral adjustment range for the magnetic shielding plate, which cannot be adapted to elevator shafts of different widths. The other end of the magnetic shielding plate bracket has a long strip hole of a predetermined length. Two guide rail clamps are symmetrically inserted into the corresponding holes to fix the other end of the magnetic shielding plate bracket to the car guide rail. Due to the limited length of the long strip hole, it cannot be used for car guide rails of different widths. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a magnetic shielding plate bracket to solve the technical problems of limited range of lateral adjustment of the magnetic shielding plate and limited car guide rail compatibility of existing magnetic shielding plate brackets, and poor versatility of magnetic shielding plate brackets.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A magnetic shielding plate bracket includes: a long, hollow mounting frame; a first adjusting component, one end of which is sleeved on the first end of the mounting frame and can slide on the mounting frame and be locked to a predetermined position, and the other end of which is connected to the magnetic shielding plate; a fixed clamping plate fixedly disposed at the second end of the mounting frame; and an adjusting clamping plate sleeved on the second end of the mounting frame. The bracket also includes: a second adjusting component, with the fixed clamping plates passing through both ends; the adjusting clamping plate can lock itself after moving to the predetermined position at the second end of the mounting frame, so that the adjusting clamping plate and the fixed clamping plate cooperate to clamp the car guide rail.

[0008] The first adjustment component enables flexible adjustment of the magnetic shielding plate on the mounting frame. It can slide along the mounting frame and lock to a predetermined position according to actual needs, improving the lateral adjustment range and adapting to elevator shafts of different sizes. The cooperative design of the fixed plate and the adjustment plate allows the mounting frame to adapt to car guide rails of different sizes, expanding the scope of application and making the entire magnetic shielding plate bracket more versatile. The long and hollow mounting frame design not only saves materials but also ensures the stability and load-bearing capacity of the structure.

[0009] In some embodiments, the first adjustment component includes: a snap nut, with both ends folded to form an arc-shaped fixing groove that fits onto the mounting bracket, and a first screw locking member through which the magnetic shielding plate and the snap nut pass;

[0010] The position of the magnetic shielding plate can be infinitely adjusted by sliding the snap nut on the mounting bracket.

[0011] In some embodiments, the edge of the fixed plate forms a first engaging hook that engages with one side surface of the car guide rail;

[0012] The design of the first locking mechanism effectively prevents the fixed plate from sliding longitudinally on the car guide rail, enhancing the reliability of the clamping. At the same time, it improves the connection accuracy between the magnetic shielding plate bracket and the car guide rail, reducing the risk of displacement caused by vibration or impact.

[0013] In some embodiments, the edge of the adjusting plate forms a second engaging hook that engages with the other side of the car guide rail;

[0014] The design of the second locking mechanism effectively prevents the adjusting plate from sliding longitudinally on the car guide rail.

[0015] In some embodiments, the second adjustment component includes: a second screw locking member through which the fixing plate and the adjustment plate are respectively passed at both ends, and a locking nut that is threadedly engaged with the second screw locking member;

[0016] The combination design of the second screw locking component and the locking nut makes the position adjustment of the adjustment plate more precise. At the same time, it is easy to operate, and locking or loosening can be completed without special tools, which improves the convenience of installation and maintenance. In addition, the threaded connection method has high reliability and durability, extending the service life of the product. Attached Figure Description

[0023] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and referring to the attached drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0024] A magnetic isolation plate bracket provided by the present utility model has a mounting frame 2 formed by bending a metal plate into a "U" shape. This special shape design not only ensures the structural strength but also significantly reduces material consumption and the overall weight is reduced by 15%, which is more conducive to on-site installation operations. Specifically, the first end of the mounting frame 2 is designed as an adjustable section, and the second end is a clamping section for the car guide rail 4, with clear functional divisions at both ends.

[0025] A first adjustment component 3 is provided at the first end of the mounting frame 2. This component consists of a snap nut 301 and a first screw locking piece 302. The inner arc surface of the snap nut 301 is closely fitted to the surface of the mounting frame 2 to form a slidable socket structure. During installation, the operator can freely slide the snap nut 301 along the length direction of the mounting frame 2 to the target position, and then lock it through the first screw locking piece 302. One end of the first screw locking piece 302 is engaged into the hole position of the magnetic isolation plate 1, and the other end is in threaded cooperation with the snap nut 301. This stepless adjustment method breaks through the spacing limitation of traditional round hole positioning, expands the lateral adjustment range, and can adapt to the elevator installation requirements of different hoistway widths.

[0026] The second end of the mounting bracket 2 employs a double clamping mechanism design. A fixing plate 5 is integrally formed or welded at the end, with its edge formed by a stamping process to create a first engaging hook 601 with a right-angle bend. A matching adjusting plate 7 is precision-cut to create a second engaging hook 701 that matches the curvature of the car guide rail 4. Both clamp the car guide rail 4 from the left and right sides respectively. It is particularly noteworthy that the inner surface of the adjusting plate 7 can be provided with anti-slip textures, generating additional friction when in contact with the car guide rail 4, effectively preventing positional shift after installation.

[0027] The second adjustment component 6 of the clamping mechanism adopts a standardized threaded fastening method. Specifically, it includes a second screw locking element 601 that penetrates the fixed clamping plate 5 and the adjusting clamping plate 7, used in conjunction with a high-strength anti-loosening locking nut 602. During installation, the locking nut 602 is initially loosened, and the adjusting clamping plate 7 is pushed along the mounting bracket 2 to a position where it is fully in contact with the car guide rail 4. Then, the locking nut 602 is gradually tightened to generate an axial clamping force. Tests have shown that this structure can generate a continuous clamping force of not less than 200N, fully meeting the vibration and impact requirements during elevator operation. Preferably, the locking nut 602 has a specially designed nylon anti-loosening ring on its surface, which ensures that the threads will not loosen due to self-rotation during long-term use.

[0028] To further improve installation reliability, the engagement hooks of both the fixing plate 5 and the adjusting plate 7 are chamfered, with the corner radius controlled within 0.5mm. This meticulous treatment not only avoids scratching the protective coating of the car guide rail 4 during installation but also ensures that the contact area between the engagement hook and the side of the car guide rail 4 reaches more than 85%.

[0029] Through the above structural combination, this magnetic shielding plate bracket achieves three core improvements: First, the annular sliding structure breaks through the limitations of traditional hole-fixed mounting, allowing the installation position of the magnetic shielding plate 1 to be continuously adjusted; second, the bidirectional snap-fit ​​hook design, combined with the threaded locking system, forms a comprehensive wrapping fixation of the car guide rail 4; finally, the modular component design allows each functional unit to work collaboratively and be replaced and maintained independently, greatly extending the product's service life.

[0030] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
