[0023] Research has found that existing cable chain support mechanisms only have good stability when subjected to vertical forces. During the movement of the cable chain, when the rubber-coated bearing is subjected to a large horizontal force, due to structural issues, the parts connected to the rubber-coated bearing will be impacted, resulting in decreased stability. The impact will also cause internal parts to loosen, reducing lifespan and increasing maintenance frequency.
[0024] Based on the above research, this disclosure provides a cable chain movable support device. By providing a support mechanism and a movable mechanism, the support mechanism supports the cable chain. As the cable chain moves horizontally, the rubber-coated bearing is driven to deflect horizontally around the axis of the movable shaft. Compared with the fixed rubber-coated bearing in the prior art, the movable rubber-coated bearing can better alleviate the horizontal impact force brought by the cable chain.
[0025] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0028] In some embodiments, such as Figure 1 and Figure 2 As shown, a set of support frames 1 are symmetrically arranged on both sides of the cable chain 2, and several sets of symmetrical support frames 1 (not shown in the figure) are arranged along the moving direction of the cable chain 2, so that the rubber-coated bearing 303 abuts against the lower end face of the cable chain 2 and provides support. As the cable chain 2 moves horizontally, the friction force drives the rubber-coated bearing 303 to rotate, which relieves part of the force exerted by the cable chain 2 on the rubber-coated bearing 303. The protective sleeve 302 arranged below the rubber-coated bearing 303 is arranged in a semi-circular arc below the rubber-coated bearing 303 and plays a guiding role. During the forward movement of the cable chain 2, it can make the support mechanism deflect stably and relieve the vertical force exerted by the cable chain 2 on the rubber-coated bearing 303.
[0029] In some embodiments, such as Figure 1 and Figure 3As shown, during the horizontal movement of the cable chain 2, a horizontal force is applied to the rubber-coated bearing 303. At this time, the rubber-coated bearing 303 drives the connecting plate 300 and the fixed plate 310 connected to it to move. The fixed plate 310 and the hinge plate 311 are connected by a movable shaft 312. The movable shaft 312 is connected to the hinge plate 311 bearing and fixed to the fixed plate 310. At this time, the rubber-coated bearing 303 deflects around the axis of the movable shaft 312. Compared with the case where the rubber-coated bearing 303 is stationary in the prior art, the rubber-coated bearing 303 deflects and moves in the direction of movement of the cable chain 2, which relieves the horizontal force received by the rubber-coated bearing 303 and prevents the parts connected to the rubber-coated bearing 303 from being impacted and becoming loose. When the movable shaft 312 rotates with the fixed plate 310, the return torsion spring 313 is deformed by force, which further relieves the horizontal force received by the support rod 301. It should be noted that as the cable chain 2 moves, the contact area between the rubber-coated bearing 303 and the lower end face of the cable chain 2 gradually decreases until it separates. Since several sets of symmetrical support frames 1 are provided on both sides of the cable chain 2, the rubber-coated bearing 303 in the subsequent support frame 1 can still play a supporting role for the cable chain 2.
[0030] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0032] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0033] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
