Abstract
Description
Technical Field
[0001] This utility model relates to the field of compact chain anti-knotting technology, specifically a side-type anti-knotting compact chain. Background Technology
[0002] A compact chain is a chain with a compact structure, commonly used in scraper conveyors and transfer conveyors in underground coal mines. The compact chain is designed to withstand complex forces, ensuring the stability and reliability of the chain connection. It is particularly suitable for high-load and extreme working conditions, such as the scenario in hard rock mining where scraper conveyors frequently bear huge tensile and impact forces.
[0003] To significantly improve the mechanical performance of the vertical ring within the same space, a side-mounted anti-knotting compact chain was developed (see patent number: 201921028360.7). This utility model includes a vertical ring and a flat ring, which are sequentially connected to each other. Two inwardly protruding blocks are provided in the middle of the vertical ring, with the protrusions facing each other. These blocks prevent the flat ring from shifting towards the middle of the inner side of the vertical ring or to the other end of the inner side of the vertical ring, thus solving the problems of knotting and chain jamming in the compact chain and changing the cross-sectional shape of both ends of the vertical ring.
[0004] However, the existing side-mounted anti-knotting compact chains, due to their structural design, require more time and effort to install and disassemble in order to ensure the stability of the connection. This reduces their utilization rate to some extent.
[0005] To solve the above problems, a side-mounted anti-knotting compact chain has emerged. Utility Model Content
[0006] The purpose of this utility model is to provide a side-mounted anti-knotting compact chain to solve the problem that the subsequent installation and disassembly are difficult due to the overly compact structure.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a side-type anti-knotting compact chain, comprising a compact chain body and a compact gear, wherein a limiting component is provided at one end of the compact chain body, and longitudinal sliding components are slidably connected to both sides of one end of the limiting component, and a limiting pressure rod extending to the other end of the limiting component is provided at the middle position of one end of the longitudinal sliding component.
[0008] The limiting component includes a support plate, and both sides of one end of the support plate are provided with limiting grooves. One end of each limiting groove is provided with a limiting hole extending to the other end of the support plate.
[0009] The longitudinal sliding components all include a sleeve, and a support rod is provided at the top and bottom of one end of the sleeve. A limiting slider that matches the limiting groove is provided at one end of the support rod. An annular groove is provided on the outside of the sleeve, and a collar is sleeved on the outside of the annular groove.
[0010] The limiting and pressing rod has multiple sets of external threads evenly arranged on one end, an elastic element is sleeved on the outside of the limiting and pressing rod, and a toggle block is provided on the other end of the limiting and pressing rod.
[0011] As a further embodiment of this utility model: the elastic element is located inside the sleeve, and both ends of the sleeve and one side of the limiting slider are provided with movable holes extending to the other end. The limiting pressure rod is movably connected to the sleeve and the limiting slider respectively through the movable holes.
[0012] As a further embodiment of this utility model: a nut matching the external thread is provided at one end of the limiting and pressing rod near the support plate. The outer diameter of the nut is larger than the inner diameter of the limiting hole. The limiting and pressing rod is detachably connected to the support plate through the mutual cooperation of the external thread and the nut.
[0013] As a further embodiment of this utility model: the limiting slider is slidably connected to the limiting groove, and the sleeve is slidably connected to the support plate through the mutual cooperation of the limiting slider and the limiting groove.
[0014] As a further improvement of this utility model: multiple sets of arc-shaped notches are evenly arranged on both sides inside the limiting hole, and one end of the limiting pressure rod is limited and connected to the limiting slide groove through the arc-shaped notches.
[0015] As a further embodiment of this utility model: the compact chain body includes a flat ring and a vertical ring, and the compact chain body is formed by overlapping and splicing the flat ring and the vertical ring together.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. By setting the limiting pressure rods, the left limiting pressure rod moves upward and the right limiting pressure rod moves downward, which can realize the tensioning operation of the compact chain body. The tension can prevent it from knotting. The operation can also be achieved by adjusting only one side of the limiting pressure rod while keeping the other side still. When disassembly is required, the left limiting pressure rod can be moved upward and the right limiting pressure rod can be moved upward, or only one side of the limiting pressure rod can be adjusted to loosen the compact chain body directly, so as to facilitate the disassembly of the compact chain body from the compact gear.
[0018] 2. By using a collar, which can roll along the outside of the sleeve under the action of the annular groove, the compact chain body located at that position can slide by itself without being affected by the frictional resistance at that position, thus making its movement more effortless.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0026] Please see Figures 1-4 In this embodiment of the utility model, a side-type anti-knotting compact chain includes a compact chain body 1 and a compact gear 5. A limiting component 2 is provided at one end of the compact chain body 1. Both sides of one end of the limiting component 2 are slidably connected to a longitudinal sliding component 3. A limiting pressure rod 4 extending to the other end of the limiting component 2 is provided at the middle position of one end of the longitudinal sliding component 3.
[0027] The limiting component 2 includes a support plate 201. Both sides of one end of the support plate 201 are provided with limiting grooves 202. One end of each limiting groove 202 is provided with a limiting hole 203 extending to the other end of the support plate 201.
[0028] The longitudinal sliding component 3 includes a sleeve 301. The top and bottom of one end of the sleeve 301 are provided with support rods 302. One end of the support rods 302 is provided with a limiting slider 303 that matches the limiting groove 202. The outside of the sleeve 301 is provided with an annular groove 304. A collar 305 is sleeved on the outside of the annular groove 304.
[0029] Among them, one end of the limiting pressure rod 4 is uniformly provided with multiple sets of external threads 403, the outside of the limiting pressure rod 4 is sleeved with an elastic element 402, and the other end of the limiting pressure rod 4 has a toggle block 401.
[0030] Elastic element 402 refers to a component that utilizes the elastic properties of materials to perform various functions. It is usually called an elastic element or spring. Elastic elements can perform functions such as transformation, isolation, sealing, compensation, energy storage and connection.
[0031] Please see Figures 1 to 4 The elastic element 402 is located inside the sleeve 301. Both ends of the sleeve 301 and one side of the limiting slider 303 are provided with movable holes extending to the other end. The limiting pressure rod 4 is movably connected to the sleeve 301 and the limiting slider 303 through the movable holes. The movable holes make the movement of the limiting pressure rod 4 easier, thus facilitating operation and reducing usage. The limiting pressure rod 4 is provided with a limiting plate on its outside. The limiting plate is located inside the sleeve 301 and is located just near the support plate 201 of the elastic element 402. This allows it to better exert pressure on the elastic element 402 during movement and makes the rebound force generated after the elastic element 402 deforms better act on the limiting pressure rod 4.
[0032] Please see Figures 1 to 4 The end of the limiting pressure rod 4 near the support plate 201 is provided with a nut that matches the external thread 403. The outer diameter of the nut is larger than the inner diameter of the limiting hole 203. The limiting pressure rod 4 is detachably connected to the support plate 201 through the mutual cooperation of the external thread 403 and the nut.
[0033] In this embodiment, the positioning limit rod 4 can be fixedly connected from the back of the support plate 201 using the provided nut, ensuring its stability and firmness after adjustment. The limiting hole 203, which is composed of multiple sets of arc-shaped notches, ensures that each pair of adjacent arc-shaped notches in the lateral direction forms the space through which the positioning limit rod 4 can be inserted. The top and bottom tracks of the arc-shaped notches allow the positioning limit rod 4 to be firmly pressed against the position and cannot move up and down, but can only be moved back and forth. After being fixed with the nut, it can no longer move back and forth, thus achieving stable support.
[0034] Please see Figures 1 to 4 The limiting slider 303 is slidably connected to the limiting groove 202, and the sleeve 301 is slidably connected to the support plate 201 through the mutual cooperation of the limiting slider 303 and the limiting groove 202, so that it can move up and down better along this position.
[0035] Please see Figures 1 to 4 Multiple sets of arc-shaped notches are evenly arranged on both sides inside the limiting hole 203. One end of the limiting pressure rod 4 is connected to the limiting slide groove 202 through the arc-shaped notches.
[0036] Please see Figures 1 to 4 The compact chain body 1 includes flat rings and vertical rings, which are spliced together by overlapping each other.
[0037] The working principle of this utility model is as follows: When in use, external tools such as wrenches can be used to remove the nuts on one of the sets of limiting pressure rods 4, and then the limiting pressure rods 4 can be pulled away from the support plate 201. The limiting pressure rods 4 can be moved away from the support plate 201 along the movable hole on the sleeve 301, and the other end of the limiting pressure rods 4 can be slowly moved out from one end of the limiting hole 203 until it moves into the interior of the limiting slider 303.
[0038] When one end of the limiting pressure rod 4 is separated from the limiting hole 203, the limiting pressure rod 4 can be directly pushed up or down, so that the limiting pressure rod 4, carrying the sleeve 301 and the support rod 302, moves up or down along the limiting slide groove 202 under the action of the limiting slider 303.
[0039] After the limiting pressure rod 4 moves to the appropriate position, the pulling force on the limiting pressure rod 4 can be released, so that the limiting pressure rod 4 moves towards the position of the limiting hole 203 under the action of the elastic element 402 until one end of the limiting pressure rod 4 is aligned with the corresponding arc-shaped notch on the limiting hole 203. Then, the limiting pressure rod 4 can be directly locked into the corresponding position under the elastic pushing force. Then, the other end of the support plate 201 can be fixedly connected with the nut to achieve the fixation of its position.
[0040] by Figure 1 For example, the left limiting pressure rod 4 moves up and the right limiting pressure rod 4 moves down to achieve the tensioning operation of the compact chain body 1. The operation can also be achieved by adjusting only one side of the limiting pressure rod 4 while keeping the other side still. When disassembly is required, the left limiting pressure rod 4 can be moved up and the right limiting pressure rod 4 can be moved up, or only one side of the limiting pressure rod 4 can be adjusted to loosen the compact chain body 1 directly, thereby facilitating the disassembly of the compact chain body 1 from the compact gear 5.
[0041] Furthermore, the collar 305 is provided, which can roll along the outside of the sleeve 301 under the action of the annular groove 304, so that the compact chain body 1 located at this position can slide by itself and will not be affected by the frictional resistance at this position, thus making its movement more effortless.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
