Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a new or modified elevator car installation frame. Background Technology

[0002] With the advancement of urbanization, a large number of elevators put into use in the early stages have entered the aging stage and face an urgent need for renovation and upgrading. In elevator renovation projects, in order to control renovation costs and shorten the construction period, the retention and utilization of reusable parts of the original elevators has become a common optimization solution adopted in the industry. Among them, the elevator guide rail, as the core guiding component for elevator operation, has a complex installation and construction process and accounts for a high proportion of costs. If the performance is confirmed to be intact after evaluation, retaining the original guide rail system can significantly reduce the total renovation cost, while avoiding the problem of extended construction period caused by guide rail removal and reinstallation, which has significant economic and engineering value.

[0003] The matching design of elevator car system and guide rail system must strictly follow specific technical rules and comprehensively consider multiple key factors such as elevator load, running speed, car balance and stability. Different elevator manufacturers have formed standardized design schemes adapted to their own product systems. However, in the scenario of old elevator renovation, when the original guide rail system is retained, the newly designed car often cannot fully match the installation parameters and adaptation requirements of the original guide rail, resulting in the inability to directly apply traditional standardized car products.

[0004] Currently, for this type of retrofitting, the market typically requires a non-standard overall design of the elevator car based on the on-site measured guide rail position parameters. This solution relies on manual labor to complete complex dimensional matching calculations and structural adaptation designs, which is not only time-consuming and labor-intensive with a long design cycle, but also prone to insufficient matching accuracy between the car and guide rails due to human calculation errors. This can lead to safety hazards such as uneven car loading, running vibration, and reduced guiding accuracy, seriously affecting the stability and safety of elevator operation. At the same time, the personalized nature of non-standard designs results in poor product versatility, making it impossible to apply in batches, further increasing the cost and implementation difficulty of retrofitting projects, and failing to meet the actual needs of efficient, accurate, and low-cost retrofitting of old elevators.

The J-shaped plate and the L-shaped plate form a U-shaped structure with folded edges on both sides. The folded edges of the U-shaped structure extend inward and match the I-shaped structure.

[0011] Preferably, the limiting component includes a locking bolt and a spring post connected to the column by a stud. One end of the spring post is threaded into the side of the column near the load-bearing channel steel, and the spring post is located below the locking bolt.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an updated or modified elevator car installation frame, including a base frame for installing the car, columns 1 for cooperating with the elevator guide rail system on both sides of the base frame, a top beam 14 for installation with the elevator car system installed at the upper end of the column 1, a bottom beam 5 for sliding connection between the bottom beam 5 and the base frame via a sliding mechanism, a limiting component for locking the movement position of the column 1 on the column 1, a support structure for stabilizing the column 1 installed between the column 1 and the base frame, and the installation position between the support structure and the column 1 is adjustable.

[0025] The base frame is configured as an U-shaped structure composed of interlaced connecting beams 2 and load-bearing channel steel 3. The geometric stability of the U-shaped structure is used to distribute the weight of the car, improve the deformation resistance and load-bearing capacity of the base frame, adapt to the needs of cars with different load specifications, and meet the requirements of the load-bearing reliability of the installation frame in the renovation of old elevators. The load-bearing channel steel 3 is located at the upper end of the connecting beam 2, and the connection between the load-bearing channel steel 3 and the connecting beam 2 is fixed by bolts. A pad 6 is provided between the load-bearing channel steel 3 and the bolt head, so that the bolt tightening force is evenly transmitted to the surface of the load-bearing channel steel 3 through the pad 6, avoiding local stress concentration and extending the service life of the installation frame.

[0026] The sliding mechanism includes a slide rail 9 fixed to the lower surface of the load-bearing channel steel 3, a slider 8 slidably connected to the slide rail 9, the slider 8 being fixed to the bottom beam 5, and an installation groove for mounting the slider 8 being provided on the bottom beam 5. Through the cooperation of the slider 8 and the installation groove, the slider 8 can be precisely fixed to the bottom beam 5. When it is necessary to adjust the position of the column 1, the slider 8 slides directionally along the slide rail 9, driving the bottom beam 5 and the connected column 1 to move synchronously, realizing the linear adjustment of the position of the column 1 to adapt to the original guide rail system of different specifications.

[0027] The slide rail 9 includes a base plate 92 fixed to the lower surface of the load-bearing channel steel 3. The lower surface of the base plate 92 is integrally formed with a convex plate 91. The convex plate 91 and the base plate 92 form an I-shaped structure. The I-shaped structure has an I-shaped cross-section. The convex plate 91 provides a symmetrical sliding support surface for the slider 8, avoiding side tipping or displacement during sliding and ensuring the stability of the column 1 adjustment.

[0028] The slider 8 includes a J-shaped plate 81 and an L-shaped plate 82. The L-shaped plate 82 is fixed to one end of the J-shaped plate 81 by bolts. The J-shaped plate 81 and the L-shaped plate 82 form a U-shaped structure with folded edges on both sides. The folded edges of the U-shaped structure extend inward and match the I-shaped structure. The inner folded edge of the slider 8 and the I-shaped structure of the slide rail 9 form a complementary interlocking relationship. The inner side of the folded edge fits against the upper and lower surfaces and the side surfaces of the I-shaped structure, realizing the wrapping sliding of the slider 8 on the slide rail 9. This ensures the degree of freedom of sliding and restricts lateral displacement, completely avoiding the risk of falling off or shifting during sliding.

[0029] Furthermore, the split design of the J-shaped plate 81 and the L-shaped plate 82 facilitates the installation, replacement and maintenance of the slider 8. If the slider 8 is worn, the component can be replaced individually without replacing the entire slide rail 9, thus reducing maintenance costs.

[0030] The limiting assembly includes a locking bolt 7 and a spring post 11 connected to the column 1 by a stud. One end of the spring post 11 is threaded into the side of the column 1 near the load-bearing channel steel 3, and the spring post 11 is located below the locking bolt 7. The load-bearing channel steel 3 has multiple limiting holes 13 for inserting the other end of the spring post 11 and multiple fixing holes 12 for screwing the locking bolt 7 on it. The multiple limiting holes 13 and fixing holes 12 on the load-bearing channel steel 3 are equidistantly distributed to provide multiple adjustment positions for the column 1. When adjusting the position of column 1, the elastic telescopic structure of spring column 11 can automatically engage with the corresponding limiting hole 13 as column 1 moves, achieving temporary positioning. When pushing column 1, a jerking sensation is produced, making it easy for personnel to accurately confirm the position of column 1 in the load-bearing channel steel 3. After the position is determined, the locking bolt 7 is screwed to the corresponding fixing hole 12 to form a permanent rigid lock. The dual structure together ensures that the position of column 1 is fixed, ensuring that column 1 will not shift during long-term use and avoiding a decrease in matching accuracy due to vibration.

[0031] The spring column 11 includes a sleeve 111 threadedly connected to the column 1. The outer wall of the sleeve 111 is provided with external threads. A compression spring 112 is fixed inside the sleeve 111. One end of the compression spring 112 is fixed with a limit block 113. The end of the limit block 113 that contacts the limit hole 13 has a semi-circular structure. The other end of the limit block 113 slides inside the sleeve 111. When the column 1 is adjusted, the limit block 113 is compressed by the surface of the load-bearing channel steel 3, causing the compression spring 112 to retract into the sleeve 111. When it moves to the position of the limit hole 13, the compression spring 112 resets and pushes the limit block 113 into the limit hole 13, achieving automatic positioning. This ensures that the column 1 can accurately engage the preset position during adjustment, avoiding over-adjustment or under-adjustment, and improving the accuracy of matching with the guide rail. The other end of the limit block 113 slides inside the sleeve 111 to ensure the directionality of the telescopic movement.

[0032] The support structure includes tie rods 4 installed obliquely on both sides of the column 1. One end of each tie rod 4 is hinged to the end of the connecting beam 2. The column 1 has multiple mounting holes 10 at equal intervals for hinged ends of the tie rods 4. These mounting holes 10 provide different hinged positions at different heights for the other end of the tie rods 4. When the position of the column 1 is adjusted, a mounting hole 10 that matches the current position of the column 1 is selected, and the other end of the tie rod 4 is hinged and fixed, so that the tie rod 4 is in a tensioned state. Through the stability principle of the triangular structure, the lateral and vertical forces borne by the column 1 are dispersed, improving the deformation resistance of the frame and structurally avoiding problems such as running vibration and decreased guiding accuracy caused by eccentric loading. The length of the tie rods 4 located on both sides of the column 1 can be adjusted according to actual needs.

[0033] During operation, the base frame serves as the basic carrier, with the two side columns 1 acting as core components that cooperate with the elevator guide rail system. The upper end forms an overall frame through the top beam 14, and the lower end is connected by the bottom beam 5 as a unified force-bearing unit. The bottom beam 5 and the base frame establish a relatively movable connection through a sliding mechanism, allowing the columns 1 to move along the load-bearing channel steel 3 to adjust their position. The limiting components on the columns 1 are used to lock the columns 1 after the position adjustment is completed, preventing the columns 1 from shifting. The support structure between the columns 1 and the base frame can improve the stability of the columns 1, and the adjustable design of the support structure and the installation position of the columns 1 allows for re-adaptation of the support points after the columns 1 are adjusted, forming a stable force-bearing system. This ensures the overall rigidity of the installation frame after adjustment, guarantees the balanced operation of the car, achieves precise matching between the car support position and the original guide rail system, adapts to various specifications of the original guide rail system, improves the versatility of the installation frame, and can be applied in batches to different old elevator renovation scenarios, further reducing the overall cost of renovation and meeting the actual needs of high efficiency, precision, and low cost in the field of old elevator renovation.
