Description

Technical Field

[0001] This utility model relates to the field of flat connecting links for mining, specifically to a super corrosion-resistant and ultra-strong flat connecting link for mining. Background Technology

[0002] In the operation system of core conveying equipment such as underground scraper conveyors and transfer conveyors, the mining flat-type connecting chain link is a key load-bearing component for chain connection. Its installation efficiency and operational stability directly affect the continuous operation capability of the entire underground conveying system. Currently, mainstream mining flat-type connecting chains on the market generally adopt a multi-component splicing structure design to meet the load-bearing strength and connection adaptability under complex working conditions. This design includes multiple independent components such as the connecting ring body, pin shaft, elastic retaining ring, positioning washer, and lock nut.

[0003] However, this type of structural design has revealed significant shortcomings in actual downhole applications: On the one hand, due to the large number of components and their dispersed shapes (such as small pin diameter and thin retaining ring thickness), small parts are prone to being lost in the humid and dusty working environment downhole, whether during temporary storage during transportation or during component inventory before installation; once a core component is missing, not only will additional parts need to be procured, causing the installation work to be interrupted, but it may also create safety hazards due to the temporary replacement of incompatible components.

[0004] On the other hand, the assembly process for multiple components must follow a fixed sequence (such as inserting the pin first, then installing the washer, and finally locking the nut and retaining ring), and some components require special tools for positioning and tightening, making the installation of a single set of connecting links time-consuming. In underground equipment maintenance or emergency repair scenarios, the lengthy installation steps will significantly extend equipment downtime, making it difficult to meet the actual needs of quickly restoring conveying operations, thereby affecting the overall production efficiency of the mine. There is an urgent need to optimize the structural design to reduce the number of components and simplify the installation process, thereby improving its practicality and reliability in underground operations. Utility Model Content

[0005] The purpose of this utility model is to provide a super corrosion-resistant and ultra-strong mining flat connecting link to solve the following technical problems: how to solve the problems of existing mining flat connecting link components being easy to lose, complicated and time-consuming to install, and increasing maintenance difficulty, and to optimize the structure.

[0006] The purpose of this utility model can be achieved through the following technical solution: a super anti-corrosion and super strong mining flat connecting chain ring, comprising: a connecting component and a snap-fit ​​component, wherein the snap-fit ​​component is rotatably installed in the middle of the connecting component; the connecting component includes a C-shaped ring, wherein an annular groove is formed in the middle of one side of the C-shaped ring, and a transverse arc groove is formed on the upper surface of both ends of the other side of the connecting component; a vertical arc slot is uniformly formed at one end of the bottom of the transverse arc groove near the middle of the side of the C-shaped ring; and a through hole and a threaded hole are respectively formed on both ends of one side of the C-shaped ring.

[0007] The snap-fit ​​assembly includes an intermediate body. A transverse arc plate is integrally formed on the upper outer surface of one end of the intermediate body. Arc-shaped inserts are evenly and symmetrically arranged on both sides of the bottom surface of the middle part of the transverse arc plate. Snap-fit ​​blocks are provided on both ends of the transverse arc plate. Protrusions are symmetrically arranged on both sides of the middle part of the intermediate body. An arc-shaped groove is formed on one end face of each protrusion. A sleeve hole is formed on the side of the intermediate body away from the transverse arc plate. A threaded rod is inserted into the center of the side of the snap-fit ​​block.

[0008] As a preferred embodiment of this utility model: the intermediate body is rotatably sleeved with the annular groove through the sleeve hole, and the arc-shaped groove at the protruding end is used to adapt to and move against the metal chain.

[0009] As a preferred embodiment of this utility model: the intermediate body is aligned and snapped into a horizontal arc plate and a horizontal arc groove at one end, and the horizontal arc plate is aligned and inserted into a vertical arc slot through an arc-shaped insert at the bottom.

[0010] As a preferred embodiment of this utility model: the threaded rod is inserted into one end of the C-ring through a through hole, and the threaded rod is threadedly connected to the other end of the C-ring through a threaded hole.

[0011] As a preferred embodiment of this utility model, both the horizontal arc groove and the vertical arc slot are set with the center of the socket hole deflected.

[0012] As a preferred embodiment of this utility model: the threaded rod is inserted through the arc-shaped plug at both ends of the C-ring, and the outer surfaces of the connecting component and the snap-fit ​​component are provided with an anti-corrosion coating.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model effectively reduces the number of components and avoids the risk of loss: the adaptable connection design can reduce the original scattered multiple independent parts, greatly reduce the overall number of components of the connecting ring, and fundamentally solve the problem of easy loss during transportation and storage caused by the dispersed shape and small size of traditional multi-components. No additional spare parts are required, avoiding the safety hazards of installation interruption or non-adaptive replacement caused by missing components, and ensuring the continuity of the operation process.

[0015] (2) This utility model significantly improves installation efficiency and shortens downtime: The adapter connection does not need to follow the traditional multi-component fixed assembly sequence, and also reduces the special tool positioning and fastening links, simplifying the installation operation process. It can greatly shorten the installation time of a single set of connecting links. Especially in the scenario of underground equipment maintenance or emergency repair, it can quickly complete the installation of connecting links, effectively shorten the equipment downtime, help the underground conveying system to quickly resume operation, and improve the overall production efficiency of the mine.

[0016] (3) This utility model greatly reduces maintenance difficulty and extends service life: the structure of the connecting ring after the adaptation and connection is simpler, and there is no need to disassemble the scattered components one by one during the later maintenance, which makes it easier to quickly locate the fault location and reduce the time and cost waste caused by blind maintenance; at the same time, the integrated structure reduces the impact of repeated disassembly and assembly on the component fitting accuracy, reduces the risk of component damage during maintenance, and indirectly extends the overall service life of the connecting ring on the basis of ensuring maintenance quality, further reducing equipment operation and maintenance costs.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6This utility model is a super corrosion-resistant and ultra-strong mining flat connecting chain ring, including: a connecting component 1 and a snap-fit ​​component 2. The snap-fit ​​component 2 is rotatably installed in the middle of the connecting component 1. The connecting component 1 includes a C-shaped ring 12. An annular groove 11 is opened in the middle of one side of the C-shaped ring 12. A transverse arc groove 13 is opened on the upper surface of both ends of the other side of the connecting component 1. A vertical arc slot 15 is evenly opened at one end of the bottom of the transverse arc groove 13 near the middle of the side of the C-shaped ring 12. A through hole 16 and a threaded hole 14 are respectively opened on both ends of one side of the C-shaped ring 12.

[0027] The snap-fit ​​assembly 2 includes an intermediate body 22. A transverse arc plate 28 is integrally formed on the upper outer surface of one end of the intermediate body 22. Arc-shaped inserts 23 are evenly and symmetrically arranged on both sides of the bottom surface of the middle part of the transverse arc plate 28. Snap-fit ​​blocks 27 are provided on both ends of the transverse arc plate 28. Protrusions 21 are symmetrically arranged on both sides of the middle part of the intermediate body 22. An arc-shaped groove 24 is opened on one end face of the protrusion 21. A sleeve hole 25 is opened on the side of the intermediate body 22 away from the transverse arc plate 28. A threaded rod 26 is inserted into the center of the side of the snap-fit ​​block 27.

[0028] The intermediate body 22 is rotatably sleeved with the annular groove 11 through the sleeve hole 25, which enables the connecting component 1 and the snap-fit ​​component 2 to be rotatably connected without separation. The arc-shaped groove 24 at one end of the protrusion 21 is used to adapt and move against the metal chain, which can limit the end of the connected chain link and ensure the stability of the connected chain link. The intermediate body 22 is aligned and snapped with the horizontal arc plate 28 at one end and the horizontal arc groove 13. The horizontal arc plate 28 is aligned and inserted with the vertical arc slot 15 through the arc-shaped insert 23 at the bottom, which can ensure that the snap-fit ​​component 2 flips and adapts and snaps with the connecting component 1.

[0029] The threaded rod 26 is inserted into one end of the C-ring 12 through the through hole 16, and the threaded rod 26 is threaded into the other end of the C-ring 12 through the threaded hole 14. This can position the connection between the connecting component 1 and the snap-fit ​​component 2. The horizontal arc groove 13 and the vertical arc slot 15 are both set with the center of the socket 25 deflected. The threaded rod 26 is inserted into the arc-shaped plug 23 inside both ends of the C-ring 12, which can position the arc-shaped plug 23 inside the vertical arc slot 15. The outer surfaces of the connecting component 1 and the snap-fit ​​component 2 are provided with an anti-corrosion coating. This coating can be set as hot-dip galvanizing, electro-galvanizing + passivation, powder electrostatic spraying, thermal spraying (flame / arc spraying) or Dacromet coating zinc coating, depending on the usage environment.

[0030] The working principle of this utility model is as follows: In core conveying equipment such as underground scraper conveyors and transfer conveyors, the mining flat-type connecting chain link is a key load-bearing component for chain connection. Its ease of connection and stability directly affect the efficiency and safety of the conveying system. Addressing the problems of cumbersome installation and easy loss of parts in traditional multi-component connecting chain links, this super corrosion-resistant and ultra-strong mining flat-type connecting chain link significantly simplifies the conveyor chain connection process through the integrated adaptation design of connecting component 1 and snap-fit ​​component 2. The specific operation is as follows:

[0031] During the connection operation, the operator does not need complicated special tools. First, rotate the threaded rod 26 of the snap-fit ​​component 2 in the opposite direction and rotate it counterclockwise along the internal thread of the threaded hole 14 until it is completely disengaged. Then, pull the threaded rod 26 horizontally so that it slides along the central channel of the snap-fit ​​block 27, disengages from the through hole of the arc-shaped insert block 23, and releases the positioning constraint.

[0032] Then, grasp the middle body 22 of the snap-fit ​​assembly 2 and pull it upward and rotate it along the axis of the socket hole 25 on the outer surface of the annular groove 11. This will cause the horizontal arc plate 28 at one end of the middle body 22 to disengage from the horizontal arc groove 13 of the connecting assembly 1. At the same time, the arc-shaped insert 23 will disengage from the vertical arc slot 15. At this time, the gap at the side end of the C-ring 12 of the connecting assembly 1 will be fully opened, and it will enter the ready-to-connect state.

[0033] Next, align the end links of the two sets of conveyor chains to be connected with the opening in the middle of the side end of the C-ring 12, and fit them into the internal cavity through the reserved gap at the side end. It is necessary to ensure that the chain links are fully embedded in the matching slots to avoid displacement affecting the connection stability. Then, with the fitting hole 25 and the annular groove 11 as the axis, pull down the intermediate body 22 to reset and flip it. Precisely control the angle so that the horizontal arc plate 28 is aligned with the horizontal arc groove 13 and the arc-shaped insert 23 is aligned with the vertical arc-shaped slot 15 until they are fully engaged, completing the initial fitting of the two sets of components.

[0034] Finally, push the threaded rod 26 horizontally so that it passes through the through hole 16 of the C-ring 12 and the center channel of the arc-shaped insert 23 in sequence until the threaded end contacts the threaded hole 14; rotate the threaded rod 26 clockwise to form a tight threaded connection until it can no longer be rotated, thus completing all operations and realizing a fast and stable connection of the conveyor chain.

[0035] In terms of application results, this design integrates traditional multiple sets of scattered components such as pins and retaining rings into two core components, reducing the number of components from the source, avoiding the problem of small parts being lost in the humid and dusty underground environment, eliminating the need for additional spare parts, avoiding installation interruptions and safety hazards; and adapting to emergency repairs underground, significantly shortening equipment downtime and improving mine production efficiency;

[0036] Furthermore, the simplified structure reduces the difficulty of later maintenance: during maintenance, the two major components can be separated by disassembling the threaded rod, without having to disassemble the small parts one by one, which facilitates fault location; and the adaptable structure has strong stability, and repeated disassembly and assembly will not reduce the fitting accuracy. Combined with the anti-corrosion coating on the outer surface, it extends the service life of the connecting ring, reduces the frequency and cost of maintenance, and fully meets the practical, reliable and economical needs of downhole operations, providing a guarantee for the safe and efficient operation of the conveying equipment.

[0037] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
