Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to an elevator balance chain anti-sway device. Background Technology
[0002] When an elevator exceeds a certain height, the length of the steel cable changes continuously during operation. To compensate for these changes, a balance chain is usually installed. During high-speed operation, the balance chain sways, especially at the bottom of the elevator shaft pit, causing noise and vibration. Sometimes, it can become entangled in the buffers, guide rails, and pit components, leading to unsafe operation and component damage. Therefore, an anti-sway device needs to be installed in the elevator shaft pit. Existing anti-sway devices consist of multiple anti-sway components arranged horizontally in a ring structure, with the balance chain passing through the center of this ring. This type of anti-sway device has the following disadvantages: 1. Complex structure, time-consuming and labor-intensive installation, and relatively weak adaptability.
[0003] Second, it cannot effectively guide the trajectory of the balance chain to achieve a better anti-sway effect.
[0004] Third, during operation, the balance chain is prone to getting stuck at the connection between the anti-sway components, causing the balance chain to jam or scrape, thereby increasing the risk of wear and damage to the balance chain and reducing its service life. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an elevator balance chain anti-sway device, which has a simple structure, is easy to install, has strong adaptability, a long service life of the balance chain and a good anti-sway effect.
[0006] This utility model is achieved through the following technical solution:
[0007] An elevator balance chain anti-sway device includes a mounting bracket and a balance chain anti-sway component. The balance chain anti-sway component is vertically mounted on the counterweight guide rail in the elevator shaft pit via the mounting bracket. The balance chain anti-sway component has a vertical smooth through hole in the middle, and the diameters at both ends of the smooth through hole are larger than the diameter in the middle.
[0008] The optimized anti-sway component of the balance chain has an outer contour that gradually tapers from both ends towards the middle, resembling a waist drum shape.
[0009] The optimized anti-sway component of the balance chain has a rectangular cross-sectional outer profile.
[0010] The optimized anti-sway component of the balance chain has a triangular outer profile in its cross-section.

[0012] Furthermore, the anti-sway component of the balance chain is slidably connected to the counterweight guide rail in the elevator shaft pit through the mounting bracket.
[0013] Furthermore, the mounting bracket includes an adjustable guide bracket and a fixed guide bracket. The adjustable guide bracket has an adjustable guide bracket elongated hole along its extension direction. The fixed guide bracket is fixedly installed on the anti-sway component of the balance chain. The fixed guide bracket is fixedly connected to the adjustable guide bracket at the adjustable guide bracket elongated hole by bolts.
[0014] The optimized design includes two adjustable guide brackets and one fixed guide bracket, with each adjustable guide bracket having one elongated hole.

[0027] An elevator balance chain anti-sway device includes a mounting bracket and a balance chain anti-sway component 4. The balance chain anti-sway component is vertically mounted on the counterweight guide rail 2 in the elevator shaft pit through the mounting bracket. The balance chain anti-sway component has a vertical smooth through hole 5 in the middle, and the diameters at both ends of the smooth through hole are larger than the diameter in the middle.
[0028] The elevator balance chain anti-sway device provided by this invention has the balance chain passing through a vertical, smooth through-hole in the middle of the balance chain anti-sway component. Since only one balance chain anti-sway component is used, it is vertically installed on the counterweight guide rail in the elevator shaft pit via a mounting bracket. This not only simplifies the structure and facilitates installation, but also, because the balance chain anti-sway component has a vertical, smooth through-hole in the middle, with the diameters at both ends of the through-hole being larger than the diameter at the middle (meaning a smooth transition between the ends and the middle), it can more effectively limit the range of balance chain swaying, correctly guide the balance chain's running trajectory, and reduce elevator noise and vibration caused by balance chain swaying and scraping. This effectively improves the safety and stability of the elevator, and the balance chain will not jam during operation, reducing the risk of balance chain wear and damage, thereby extending the service life of the balance chain.
[0029] The optimized outer contour of the anti-sway component of the balance chain can preferably be a waist drum shape that gradually tapers from both ends to the middle.
[0030] The optimized anti-sway component of the balance chain has a rectangular cross-sectional outer profile.
[0031] The optimized anti-sway component of the balance chain has a triangular outer profile in its cross-section.
[0032] The optimized anti-sway component of the balance chain has an irregular, non-circular cross-sectional profile.
[0033] The elevator balance chain anti-sway device provided by this invention has certain requirements for the internal through hole, since the balance chain passes through the vertical smooth through hole in the middle of the balance chain anti-sway component. However, it has almost no requirements for the external contour and smoothness, and can be any shape. Compared with the existing technology, which has multiple anti-sway components arranged horizontally to form a ring structure, the balance chain passes through the middle of the ring structure formed by multiple anti-sway components. This makes the manufacturing and installation more convenient. The existing technology has relatively high requirements for the external contour of the anti-sway component.
[0034] Furthermore, the anti-sway component of the balance chain is slidably connected to the counterweight guide rail in the elevator shaft pit via a mounting bracket. This allows the position of the anti-sway component to be moved as needed to accommodate different models, specifications, and types of balance chains.
[0035] Furthermore, the mounting bracket includes an adjustable guide bracket 1 and a fixed guide bracket 3. The adjustable guide bracket has an adjustable guide bracket elongated hole 6 along its extension direction. The fixed guide bracket is fixedly installed on the anti-sway component of the balance chain. The fixed guide bracket is fixedly connected to the adjustable guide bracket at the adjustable guide bracket elongated hole by bolts.
[0036] The fixed guide bracket and the anti-sway component of the balance chain can be connected as a single unit or fixed in other ways.
[0037] By moving the fixed guide bracket along the elongated hole of the adjustable guide bracket, the position of the anti-sway component of the balance chain can be adjusted to further adapt to the needs of different models, specifications, and types of balance chains, and the adjustment is convenient and quick.
[0038] A schematic diagram of the specific embodiment one is shown below. Figure 1 , Figure 2 As shown, there are two adjustable guide brackets and one fixed guide bracket, with each adjustable guide bracket having one elongated hole. This not only achieves a good fixing effect on the anti-sway component of the balance chain, but also allows adjustment of the angle of the anti-sway component by adjusting the height of the two adjustable guide brackets, thereby further adapting to the needs of different models, specifications, and types of balance chains.
[0039] A schematic diagram of the structure of specific embodiment two is shown below. Figure 3 , 4 As shown, there is one adjustable guide bracket and two fixed guide brackets. The adjustable guide bracket has multiple elongated holes spaced apart, which not only facilitates the adjustment of the position of the anti-sway components of the balance chain, but also ensures the strength of the adjustable guide bracket and the fixing effect of the anti-sway components of the balance chain. In addition, multiple anti-sway components of the balance chain can be installed at the elongated holes of the adjustable guide bracket as needed.
[0040] The optimized design features a fixed guide bracket with a long hole 7 corresponding to the long hole of the adjustable guide bracket, further facilitating the fixed connection between the fixed guide bracket and the adjustable guide bracket.
[0041] In summary, the elevator balance chain anti-sway device proposed in this utility model has a simple structure, is easy to install and adjust, has strong adaptability, good anti-sway effect, and can extend the service life of the balance chain.
[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
