Description

Technical Field

[0001] This utility model relates to the field of elevator gantry technology, and in particular to an elevator gantry. Background Technology

[0002] An elevator gantry is a structure used to support and fix elevator equipment. It is usually made of steel and can be fixed to the wall or ground of a building to provide stable support and protection for the elevator. It can bear the weight of the elevator equipment and resist the influence of the external environment to ensure the safe operation of the elevator equipment.

[0003] Traditional elevator gantry frames may lack flexibility during installation, leading to a complex and time-consuming process. Furthermore, the imprecise positioning mechanism can negatively impact the overall performance and operational efficiency of the elevator. Additionally, traditional elevator gantry frames may lack vibration absorption systems, making it difficult to effectively mitigate vibrations generated during elevator operation. This not only reduces passenger comfort but may also cause long-term dynamic loads on the elevator structure, shortening the lifespan of elevator components and increasing long-term maintenance costs.

[0004] Therefore, those skilled in the art have provided a gantry for elevators to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an elevator gantry frame. This elevator gantry frame significantly improves the flexibility of the installation process and the accuracy of positioning through a sliding connection mechanism. The quick-connect limiting function of the snap-fit ​​plate and the support groove, combined with the assistance of the return spring, makes installation more convenient while ensuring the stable positioning of the gantry frame body.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An elevator gantry frame includes a gantry frame body and an elevator car. The upper end of the elevator car has an installation cavity. The middle of both sides of the outer wall of the gantry frame body is provided with a snap-fit ​​plate. The four corners of the lower end of the gantry frame body are provided with damping rods. The lower end of the gantry frame body is provided with multiple figure-eight springs.

[0008] The above technical solution, through the figure-eight spring, damping rod and connecting spring configured between the slide plate and the gantry frame, constitutes a highly efficient vibration absorption system. This system provides fine-tuning space for the movement of the elevator car, thereby improving ride comfort. By reducing the vibration generated during elevator operation, it enhances the overall stability of the elevator, helps to resist the impact of dynamic loads on the elevator structure, and thus extends the service life of elevator components and helps to reduce long-term maintenance costs.

[0009] Furthermore, a fixing groove is provided in the middle of both sides of the outer wall of the gantry frame. A plurality of return springs are fixedly connected to one end of the inner wall of the fixing groove near the center of the gantry frame. The end of the return spring away from the fixing groove is fixedly connected to the outer wall of the snap-fit ​​plate.

[0010] The above technical solution, through the design of the fixing groove, makes the arrangement of the reset spring and the snap-fit ​​plate more compact, saving space, while not affecting the function of the spring.

[0011] Furthermore, the upper ends of the damping rod and the figure-eight spring are fixedly connected to the lower surface of the gantry frame, and the lower ends of the damping rod and the figure-eight spring are fixedly connected to a connecting plate. The inner bottom surface of the mounting cavity is provided with multiple sliding grooves.

[0012] Through the above technical solution, the damping rod helps to absorb the vibration generated during elevator operation through its damping characteristics, while the figure-eight spring provides additional elastic support. The combination of the two enhances the stability of elevator operation.

[0013] Furthermore, the middle part of the lower surface of the gantry frame slides against the inner wall of the connecting plate;

[0014] The above technical solution can ensure the stability of the connecting plate in the vertical direction and prevent it from shifting horizontally.

[0015] Furthermore, slots are provided on the upper part of both sides of the outer wall of the elevator car, and support grooves are provided on the upper part of both sides of the inner wall of the mounting cavity, and the support grooves are all in communication with the inside of the slots.

[0016] The above technical solution allows for quick adjustment of the snap-fit ​​plate through the through slot and support groove, simplifying the separation of the gantry frame and the elevator car.

[0017] Furthermore, guide shoes are fixedly connected to the upper part of the outer walls on both sides of the gantry frame;

[0018] Through the above technical solution, the guide shoes are fixed on both sides of the gantry frame to provide stable vertical guidance for the elevator car, ensuring that the car moves accurately along the guide rail during operation.

[0019] Furthermore, the lower end of each connecting plate is fixedly connected to multiple sliding plates, and the outer wall of each sliding plate slides against the inner wall of the groove.

[0020] The above technical solution reduces friction between the sliding plate and the inner wall of the groove by designing the sliding plate to slide, thereby reducing energy loss and improving the overall efficiency of the system.

[0021] Furthermore, each of the damping rods is fitted with a connecting spring on its outer wall;

[0022] By using the above technical solutions, the connecting springs help reduce energy loss caused by friction by reducing vibration during elevator operation.

[0023] This utility model has the following beneficial effects:

[0024] 1. The elevator gantry frame proposed in this utility model, compared with the existing elevator gantry frames, significantly improves the flexibility of the installation process and the accuracy of positioning through the sliding connection mechanism. The quick snap-fit ​​limiting function of the snap-fit ​​plate and the support groove, combined with the assistance of the return spring, makes the installation more convenient, while ensuring the stable positioning of the gantry frame body.

[0025] 2. The elevator gantry frame proposed in this utility model, compared with the existing elevator gantry frames, forms a highly efficient vibration absorption system by configuring a figure-eight spring, damping rod and connecting spring between the slide plate and the gantry frame body. This system provides fine-tuning space for the movement of the elevator car, thereby improving the ride comfort. By reducing the vibration generated during elevator operation, it enhances the overall stability of the elevator, helps to resist the impact of dynamic loads on the elevator structure, and thus extends the service life of elevator components and helps to reduce long-term maintenance costs.

[0034] 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.

[0035] Reference Figure 1-6 One embodiment provided by this utility model:

[0036] An elevator gantry includes a gantry body 2 and an elevator car 1. The upper end of the elevator car 1 is provided with an installation cavity 5. The middle of both sides of the outer wall of the gantry body 2 is provided with a snap-fit ​​plate 12. The four corners of the lower end of the gantry body 2 are provided with damping rods 13. The lower end of the gantry body 2 is provided with multiple figure-eight springs 15.

[0037] By configuring the figure-eight spring 15, damping rod 13 and connecting spring 14 between the slide plate 10 and the gantry frame 2, a highly efficient vibration absorption system is formed. This system provides fine-tuning space for the movement of the elevator car 1, thereby improving ride comfort. By reducing the vibration generated during elevator operation, the overall stability of the elevator is enhanced, which helps to resist the impact of dynamic loads on the elevator structure, thereby extending the service life of elevator components and helping to reduce long-term maintenance costs.

[0038] Fixed grooves 7 are provided in the middle of both sides of the outer wall of the gantry frame 2. Multiple return springs 11 are fixedly connected to one end of the inner wall of the fixed groove 7 near the center of the gantry frame 2. The end of the return spring 11 away from the fixed groove 7 is fixedly connected to the outer wall of the snap-fit ​​plate 12. The design of the fixed groove 7 makes the arrangement of the return spring 11 and the snap-fit ​​plate 12 more compact, saving space, while not affecting the function of the spring. The upper ends of the damping rod 13 and the figure-eight spring 15 are fixedly connected to the lower surface of the gantry frame 2. The lower ends of the damping rod 13 and the figure-eight spring 15 are fixedly connected to the connecting plate 9. Multiple sliding grooves 8 are provided in the inner bottom surface of the mounting cavity 5. The damping rod 13 helps to absorb the vibration generated during the operation of the elevator through its damping characteristics, while the figure-eight spring 15 provides additional elastic support. The combination of the two enhances the stability of the elevator operation. The middle of the lower surface of the gantry frame 2 slides with the inner wall of the connecting plate 9, which can ensure the stability of the connecting plate 9 in the vertical direction and prevent it from shifting horizontally.

[0039] Slots 4 are provided on the upper part of both sides of the outer wall of the elevator car 1, and support grooves 6 are provided on the upper part of both sides of the inner wall of the mounting cavity 5. The support grooves 6 are all connected to the interior of the slots 4. The through slots 4 and support grooves 6 allow for quick adjustment of the snap-fit ​​plate 12, simplifying the separation of the gantry frame 2 and the elevator car 1. Guide shoes 3 are fixedly connected to the upper part of both sides of the outer wall of the gantry frame 2. The guide shoes 3 are fixed to both sides of the gantry frame 2 to provide stable vertical guidance for the elevator car and ensure that the car moves accurately along the guide rail during operation. Multiple sliding plates 10 are fixedly connected to the lower end of the connecting plate 9. The outer wall of the sliding plate 10 slides against the inner wall of the slide groove 8. The sliding design of the sliding plate 10 against the inner wall of the slide groove 8 reduces the friction between the two, thereby reducing energy loss and improving the overall efficiency of the system. Connecting springs 14 are sleeved on the outer wall of the damping rod 13. By reducing the vibration during elevator operation, the connecting springs 14 help reduce the energy loss caused by friction.

[0040] Working Principle: The elevator gantry uses a sliding connection mechanism, which significantly improves the flexibility and positioning accuracy of the installation process. The quick-connect limiting function of the snap-fit ​​plate 12 and the support groove 6, combined with the assistance of the return spring 11, makes installation more convenient and ensures the stable positioning of the gantry body 2. The figure-eight spring 15, damping rod 13 and connecting spring 14 configured between the slide plate 10 and the gantry body 2 constitute an efficient vibration absorption system. This system provides fine-tuning space for the movement of the elevator car 1, thereby improving the ride comfort. By reducing the vibration generated during elevator operation, the overall stability of the elevator is enhanced, which helps to resist the impact of dynamic loads on the elevator structure, thereby extending the service life of elevator components and helping to reduce long-term maintenance costs.
