Description

Technical Field

[0001] This utility model relates to the field of elevator auxiliary equipment technology, and in particular to an elevator counterweight fixing device with a buffer and vibration damping layer. Background Technology

[0002] The elevator counterweight fixing device is a mechanical structural component in the elevator counterweight system used to stably and firmly fix the counterweight to the counterweight frame. Its main function is to prevent the counterweight from shifting, shaking, or falling off during elevator operation through specific connection methods and locking mechanisms, ensuring that the weight of the counterweight acts stably on the counterweight frame, thereby balancing the weight of the car and ensuring the safety and stability of elevator operation.

[0003] Elevator counterweight fixing devices with buffer and vibration damping layers are mechanical structural components that add buffer and vibration damping functions to the traditional elevator counterweight fixing devices. They are mainly used to fix the counterweight to the counterweight frame, while the buffer and vibration damping layer reduces the vibration and impact on the counterweight during elevator operation. It can absorb and buffer the vibration and impact forces generated during elevator operation, reduce the swaying and noise of the counterweight, and also extend the service life of the counterweight and counterweight frame. However, in existing elevator counterweight fixing devices with buffer and vibration damping layers, the load-bearing capacity of the buffer and vibration damping materials is relatively limited. In heavy-load elevators, the buffer spacing cannot be adapted to bear the weight of the counterweight, which is prone to deformation and damage. It is not suitable for elevators that need to start and stop frequently and are heavily loaded, requiring the selection of thicker and stronger buffer and vibration damping layers, but this will increase the maintenance cost of the device.

A buffer mechanism 2 is fixedly connected to the middle of the inner wall of the counterweight frame 1 for buffering and vibration damping. A wear-resistant mechanism 3 is fixedly connected to the top of the outer wall of the counterweight frame 1 for reducing structural friction.

A partition 205 is fixedly connected to the front and rear sides of the outer wall of the buffer pad 204.

Its bottom support leg 202 is slidably connected to the adjusting plate 203, allowing the adjusting plate 203 to move flexibly to cope with different degrees of impact. The buffer pad 204 on the top of the inner wall of the fixed frame 201 absorbs part of the impact force through elastic deformation, playing a preliminary buffering role. The partitions 205 on the front and rear sides of its outer wall limit and protect the buffer pad 204, preventing excessive displacement.

The connecting frame 301 is fixed to the top of the counterweight frame 1, and the adjusting rods 302 on the left and right sides of its top can be slidably adjusted to adapt to different sliding working states. The fixed bracket 303 in the middle of the bottom wall of the connecting frame 301 supports the rotating shaft 304. The roller 306 is fixed to the bottom of the outer wall of the rotating shaft 304 with screws 305. The roller 306 converts sliding friction into rolling friction, reducing friction loss. When the counterweight frame 1 moves, the roller 306 rotates, reducing friction. The connecting component 307 enhances the stability and adaptability of the wear-resistant mechanism 3. The support frame 3071 is fixed to the bottom of the inner wall of the connecting frame 301 to provide support.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A cover plate 6 is installed on the top of the outer wall of the guide wheel 4. A gasket 7 passes through the front and rear sides of the outer wall of the guide wheel 4. A connecting rod 8 is fixedly connected to the bottom front and rear sides of the fixed frame 201.

A positioning frame 12 is fixedly connected to the top of the outer wall of the connecting column 3073. A nut 13 is threadedly connected to the bottom of the outer wall of the connecting column 3073. Specifically, during the operation of the overall device, the cover plate 6 installed on the top of the guide wheel 4 can effectively prevent external dust and debris from entering the working area of ​​the guide wheel 4, thus playing a protective role. The gasket 7 penetrating the front and rear sides of the guide wheel 4 reduces direct friction between the guide wheel 4 and surrounding components when the guide wheel 4 rotates, reducing wear. The connecting rod 8 and connecting plate 9 at the bottom of the fixed frame 201 cooperate with each other. When the device vibrates during operation, the buffer pad 204 will play a buffering and shock-absorbing role, improving the stability of the device operation. The sliding grooves 11 opened on the left and right sides of the outer wall of the counterweight frame 1 are for the sliding block 10. A sliding track is provided, and the slider 10 slides in the middle of the inner side of the slide groove 11, which can guide the counterweight frame 1 to move up and down according to the predetermined trajectory, ensuring the accuracy and stability of the movement of the counterweight frame 1 and avoiding problems such as deviation. The positioning frame 12 connected to the connecting column 3073 plays a role in positioning and fixing, ensuring that the connection position of the connecting column 3073 and other related components is accurate. The nut 13 threaded at the bottom of the outer wall of the connecting column 3073 is tightened to fix the connecting column 3073 to the component below, preventing the connection from loosening and ensuring the reliability of the entire connection structure.

[0021] Working Principle: Regarding the buffer mechanism 2, when the elevator vibrates or the counterweight is impacted, the fixed frame 201 within the buffer mechanism 2 serves as the basic frame, providing stable support for the entire mechanism. The sliding connection between its bottom support leg 202 and the adjusting plate 203 allows the adjusting plate 203 to move flexibly on the support leg 202, initially addressing impacts of varying degrees. The buffer pad 204 at the top of the fixed frame 201 absorbs some of the impact force through its elastic deformation, providing initial buffering. The partitions 205 on the front and rear sides of the outer wall of the buffer pad 204 limit and protect it, preventing excessive displacement during deformation. The limiting plate 206 on one side of the fixed frame 201 restricts the displacement of the entire buffer mechanism 2, ensuring it operates within a reasonable range. The adjusting component 207 plays an adjusting and buffering role during the buffering process. The fixed frame 2071 is fixed to the upper and lower inner walls of the fixed frame 201, providing an installation base for the adjusting component 207. The movable groove 2072 on one side of the inner wall of the fixed frame 2071 provides a path for the sliding of the cross frame 2075. When impacted, the cross frame 2075 will slide in the movable groove 2072. At the same time, the hydraulic rod 2073 rotatably connected to the other side of the cross frame 2075 will extend and retract. The extension and retraction of the hydraulic rod 2073 can slowly release the impact force and play a buffering role. The spring 2074 connected to the hydraulic rod 2073 will deform with the extension and retraction of the hydraulic rod 2073, further absorbing and buffering the impact force. The elastic restoring force of the spring assists the hydraulic rod 2073 to reset, enhancing the buffering performance and reset capability of the entire buffer mechanism 2. The wear-resistant mechanism 3 is mainly used to reduce the friction between the counterweight frame 1 and other components during operation. By adopting wear-resistant materials or special structural design, the wear-resistant mechanism 3 reduces the wear between the counterweight frame 1 and components such as the guide wheel 4, improves the service life and operational stability of the entire device, and ensures that the elevator counterweight can work stably for a long time. The wear-resistant mechanism 3 is mainly used to reduce friction between the counterweight frame 1 and other components during operation. The connecting frame 301 is fixed to the top of the inner wall of the counterweight frame 1 and is the basic frame of the wear-resistant mechanism 3. The adjusting rods 302, which are slidably connected to the left and right sides of its top, can be adjusted according to the actual operating conditions to adapt to different working states and ensure the flexibility of the mechanism. The fixing bracket 303 in the middle of the bottom wall of the connecting frame 301 provides installation support for the rotating shaft 304. The screws 305 threaded to the bottom of the outer wall of the rotating shaft 304 are used to fix the roller 306. The roller 306 can convert the sliding friction of the counterweight frame 1 into rolling friction during operation, which greatly reduces friction loss. When the counterweight frame 1 moves, the roller 306 rotates, reducing the degree of friction with other components. The connecting component 307 The stability and adaptability of the wear-resistant mechanism 3 are further enhanced. The support frame 3071 is fixed to the bottom of the inner wall of the connecting frame 301, providing support for the entire connecting assembly 307. The limiting blocks 3074 fixed on the left and right sides of the support frame 3071 play a limiting role for the connecting column 3073, preventing the connecting column 3073 from excessively shifting during movement. The connecting column 3073, which runs through the inner wall of the limiting block 3074, is connected to the second spring 3072, which can deform when the connecting column 3073 is subjected to force, absorbing part of the vibration and impact force. At the same time, with the help of the elastic restoring force of the spring, the connecting column 3073 can be reset in time, ensuring the stability of the connection between the components of the wear-resistant mechanism 3, thereby improving the service life and operational stability of the entire device, and ensuring that the elevator counterweight can work stably for a long time.
