Abstract
Description
Technical Field
[0001] This utility model applies to the field of track chain technology, and provides a track chain with a limiting rotating link and a unidirectional limiting bending. Background Technology
[0002] Traditional track chains typically have bidirectional bending capability (i.e., they can bend both inwards and outwards). While this design enhances flexibility, in some applications, when the chain bends inwards, it can easily come into contact with the internal housing or other components of the equipment, leading to additional friction and wear. This not only reduces the lifespan of the equipment but also increases maintenance costs. Therefore, there is an urgent need for a chain structure that can achieve unidirectional bending to solve the above problems. Utility Model Content
[0003] Therefore, this utility model provides a track chain with a limiting rotating link and a one-way limiting bending mechanism. By adding a limiting mounting plate to the upper end face of a single link, and by reasonably designing the size and position of the limiting mounting plate, when two adjacent links of the chain bend inward to a certain angle, the limiting mounting plates of the two adjacent links abut against each other, thereby preventing the two links from bending further inward.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a limiting rotating chain link, comprising a first chain plate and a second chain plate spaced apart, wherein a first inner end plate and a first outer end plate are respectively provided at the left and right ends of the first chain plate, and a second inner end plate and a second outer end plate are respectively provided at the left and right ends of the second chain plate, wherein the distance between the outer side of the first inner end plate and the outer side of the second inner end plate is not greater than the distance between the inner side of the first outer end plate and the inner side of the second outer end plate, and a limiting mounting plate is provided at the upper end of the first chain plate and the second chain plate, wherein the limiting mounting plate is fixedly connected to the first chain plate and the second chain plate respectively.
[0005] Furthermore, reinforcing limiting blocks are fixedly installed on the upper sides of the left and right edges of the limiting mounting plate.
[0006] Furthermore, the first inner end plate and the second inner end plate are fixedly connected by an end plate connecting shaft.
[0007] Furthermore, it also includes an inner end plate connecting hole, which is provided sequentially through the first inner end plate, the end plate connecting shaft and the second inner end plate. The first outer end plate is provided with a first outer end connecting hole, and the second outer end plate is provided with a second outer end connecting hole that matches the first outer end connecting hole.
[0008] Furthermore, both the first and second chain plates are provided with several hollowed-out weight-reduction holes.
[0009] Furthermore, the limiting mounting plate is provided with positioning pin holes and several fixing mounting holes.
[0010] It also provides a unidirectional limiting and bending track chain composed of several of the aforementioned limiting and rotating links, with the aforementioned limiting and rotating links being hinged end to end to form a ring chain.
[0011] Furthermore, in the plurality of limiting rotating links that are hinged end to end in sequence, the first inner end plate and the second inner end plate of the latter limiting rotating link are inserted between the first outer end plate and the second outer end plate of the former limiting rotating link, and the latter limiting rotating link and the former limiting rotating link are hinged together by a connecting shaft that passes through the first outer end connecting hole, the inner end plate connecting hole and the second outer end connecting hole in sequence.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In the solution of this utility model, by adding a limiting mounting plate to the upper end of the first chain plate and the second chain plate, the track chain formed by this limiting rotating chain link can only bend inward and cannot bend outward. This structure avoids the track chain from contacting the inner shell inward, reducing travel resistance and component wear.
[0014] 2. By adding a reinforcing limiting block at the contact point between the limiting mounting plates of the two limiting rotating chain links, the strength of this position is improved, and wear caused by long-term contact is avoided from affecting the limiting effect.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example, see attached document Figure 1 The present invention provides a limiting rotation link 100, the structure of which includes a first chain plate 110 and a second chain plate 120 spaced apart. In actual design, in order to ensure modularity and operational stability, the first chain plate 110 and the second chain plate 120 are usually mirror-symmetrical structures, as shown in the attached figure. Figure 2 As shown, the first chain plate 110 has a first inner end plate 111 and a first outer end plate 112 at its left and right ends, respectively. The second chain plate 120 has a second inner end plate 121 and a second outer end plate 122 at its left and right ends, respectively. The distance between the outer side of the first inner end plate 111 and the outer side of the second inner end plate 121 is not greater than the distance between the inner side of the first outer end plate 112 and the inner side of the second outer end plate 122. This is so that when the two limiting rotating chain links 100 are connected, the first inner end plate 111 and the second inner end plate 121 of the latter limiting rotating chain link 100 can be inserted between the first outer end plate 112 and the second outer end plate 122 of the former limiting rotating chain link 100. The upper ends of the first chain plate 110 and the second chain plate 120 are provided with limiting mounting plates 130, which are fixedly connected to the first chain plate 110 and the second chain plate 120, respectively. Figure 3As shown, reinforcing limiting blocks 131 are fixedly installed on the upper sides of the left and right edges of the limiting mounting plate 130. Since the first chain plate 110 and the second chain plate 120 are only connected by the limiting mounting plate 130 at their upper ends, after long-term use, bending deformation may occur at the connection between the first chain plate 110, the second chain plate 120 and the limiting mounting plate 130. At this time, the relative position between the first chain plate 110 and the second chain plate 120 changes, which will lead to a decrease in the performance of the overall chain link. In order to ensure the spacing between the first chain plate 110 and the second chain plate 120 Even after prolonged use, it still meets the usage requirements. The first inner end plate 111 and the second inner end plate 121 are fixedly connected by an end plate connecting shaft. At the same time, inner end plate connecting holes are provided at the positions of the first inner end plate 111, the end plate connecting shaft, and the second inner end plate 121. The inner end plate connecting holes are sequentially provided through the first inner end plate 111, the end plate connecting shaft, and the second inner end plate 121. Meanwhile, the first outer end plate 112 is provided with a first outer end connecting hole 113, and the second outer end plate 122 is provided with a second outer end connecting hole 123 that matches the first outer end connecting hole 113.
[0026] In a more optimized solution, in order to reduce weight and power loss, both the first chain plate 110 and the second chain plate 120 are provided with several hollow weight-reducing holes 114.
[0027] In a further embodiment, to facilitate the installation of parts such as track plates, the limiting mounting plate 130 is provided with positioning pin holes 132 and several fixing mounting holes 133. The positioning pin holes 132 enable quick positioning of the parts, and the fixing mounting holes 133 are used for fastening by bolts or other fastening mechanisms.
[0028] It also provides a unidirectional limiting bending track chain composed of several of the aforementioned limiting rotation links 100, as shown in the attached figure. Figure 4 As shown, the track chain is formed by hinged end-to-end a number of the aforementioned limiting rotating links 100. The last limiting rotating link 100 is ultimately hinged to the first limiting rotating link 100 to form a complete circular chain. Among the several limiting rotating links 100 hinged end-to-end, as shown in the attached diagram... Figure 5 As shown, the first inner end plate 111 and the second inner end plate 121 of the subsequent limiting rotation link 100 are inserted between the first outer end plate 112 and the second outer end plate 122 of the preceding limiting rotation link 100. The subsequent limiting rotation link 100 and the preceding limiting rotation link 100 are hinged together by a connecting shaft 200 that passes sequentially through the first outer end connecting hole 113, the inner end plate connecting hole, and the second outer end connecting hole 123. In actual use of the chain, when two adjacent limiting rotation links 100 bend outwards to a certain angle, as shown in the attached diagram... Figure 6As shown, at this time, the two adjacent limit rotating links 100 bend outward to the same horizontal line. At this time, the limit mounting plates 130 of the two limit rotating links 100 come into contact with each other, which will prevent the two adjacent limit rotating links 100 from bending outward further. This can avoid the track chain from being concave inward and scraping against other structures inside the track chain after bending outward, causing problems such as chain wear and disengagement. The reinforcing limit blocks 131 are fixedly installed on the upper side of the left and right edges of the limit mounting plates 130 to strengthen the contact position of the two limit mounting plates 130 during use and avoid wear leading to insufficient subsequent limiting.
