Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-strength compact chain technology, and more specifically, to a high-strength compact chain. Background Technology
[0002] In modern automated and mechanized coal mining, scraper conveyors and transfer conveyors are used for transportation. The main components responsible for power transmission and coal transportation are chains. High-strength compact chains for mining are composed of interlocking round and flat rings. The round rings are made by heating round bars and weaving them into open chain links according to the shape of the core in a weaving machine. Then, the openings are welded together to form a closed loop.
[0003] Most existing high-strength compact chains for mining are subjected to bending loads during use, which makes the weld joints of the welded compact chains extremely prone to fatigue fracture.
[0004] A search revealed a Chinese patent with publication number CN215214572U that discloses a high-strength compact chain for mining. This utility model, by setting a first spring, bolts, locking connecting blocks and connecting plates, enables the high-strength compact chain to withstand bending loads during use, thus preventing the weld joints of the welded compact chain from easily fatigue-breaking.
[0005] However, in actual use, the high-strength compact chain is subject to severe vibrations during the operation of mining equipment. This vibrations can cause the compact chain itself to vibrate, and the screws may loosen or fall off, leading to chain link separation and affecting the stability of the compact chain. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength compact chain to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A high-strength compact chain includes two vertical rings, with a splicing mechanism on one side of each vertical ring. The splicing mechanism includes two horizontal rings, the inner sides of which engage with the inner sides of the vertical rings. A slot is formed on one side of each horizontal ring. Multiple pads are fixedly connected to the inner side of each horizontal ring. Multiple sliding grooves are formed on the outer side of each horizontal ring. Two rotating blocks are slidably connected to the inner side of each rotating block. A rod is fixedly connected to one side of each rotating block, and the outer side of the rod is inserted into the inner side of the horizontal ring. Two guide blocks are fixedly connected to the outer side of each rotating block, and the outer sides of the guide blocks are slidably connected to the inner sides of the sliding grooves. One end of the rod has an external thread. A rotating block two is provided on the outer side of the external thread. An internal thread is provided on the inner side of the rotating block two. The inner side of the internal thread is threadedly connected to the outer side of the external thread. Two springs are fixedly connected to the inner side of the transverse ring. A limit block is fixedly connected to one end of each spring. The outer side of the limit block is slidably connected to the inner side of the transverse ring. One side of the limit block is engaged with the outer side of the rotating block two. A locking block is fixedly connected to the other side of the transverse ring. Two insertion holes are provided on the outer side of the locking block. The inner side of each insertion hole is engaged with the outer side of the insertion rod. Multiple locking grooves are provided on the outer side of the locking block. The inner side of each locking groove is engaged with the outer side of the pad strip. A buffer mechanism is provided on the outer side of the transverse ring.
[0009] By adopting the above technical solution: a pair of locking blocks are inserted into the slots on one side of the two horizontal rings, and the corresponding rotating block one and the insertion rod are used to fix the slot two and the insertion hole through. At the same time, the corresponding spring and the limiting block are used to lock and limit the outer side of the rotating block two, so that the two horizontal rings are kept firmly connected.
[0010] As a further description of the above technical solution: the buffer mechanism includes multiple graphite strips, the outer side of the graphite strips is fixedly connected to the outer side of the horizontal ring, the graphite strips are arranged in a ring array on the outer side of the horizontal ring, two outer shells are fixedly connected to the inner side of the two horizontal rings, the inner side of the outer shells is rotatably connected to a limiting ball, and the outer side of the horizontal rings is rotatably connected to a rotating ring.
[0011] By adopting the above technical solution, graphite strips are used to lubricate the vertical and horizontal rings, and the sliding friction between the vertical and horizontal rings is converted into rotational friction through a rotating ring, thereby reducing the heat generated by friction.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. By setting up a splicing mechanism, compared with the existing technology, the two horizontal rings can be quickly connected by the opposing assembly of the first slot and the second slot, which facilitates the segmented maintenance and replacement of the compact chain. The corresponding pad and the second slot are used for pre-positioning, which makes it easy for the two horizontal rings to be connected by the insertion rod. The second rotating block is limited by the limit block to prevent the second rotating block from loosening after the screw is tightened, so that the compact chain maintains good connection stability during long-term operation and vibration.
[0014] 2. By setting up a buffer mechanism, compared with the existing technology, the lubricating film formed on the surface of the horizontal ring by multiple graphite strips can reduce the direct contact between metals, reduce adhesive wear and abrasive wear. At the same time, by using the deflection of the rotating ring, the sliding friction at the contact point between the vertical ring and the horizontal ring is changed into rolling friction, which can reduce the coefficient of friction and improve the service life of the compact chain.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] The embodiments disclosed in this application are as follows: Figure 1-6The high-strength compact chain shown includes two vertical rings 1, with a splicing mechanism on one side of each vertical ring 1. The splicing mechanism includes two horizontal rings 2, the inner side of which engages with the inner side of the vertical rings 1. A slot 3 is formed on one side of each horizontal ring 2. Multiple pads 4 are fixedly connected to the inner side of each horizontal ring 2. Multiple sliding grooves 5 are formed on the outer side of each horizontal ring 2. Two rotating blocks 6 are slidably connected to the inner side of each rotating block 6. A rod 7 is fixedly connected to one side of each rotating block 6, and the outer side of the rod 7 engages with the inner side of the horizontal ring 2. Two guide blocks 8 are fixedly connected to the outer side of each rotating block 6, and the outer side of each guide block 8 slidably connects with the inner side of the sliding grooves 5. One end of the rod 7 has an external thread 9. A rotating block 10 is provided outside the external thread 9. An internal thread 11 is formed inside the rotating block 10, and the inner side of the internal thread 11 is threadedly connected to the outer side of the external thread 9. Two springs 15 are fixedly connected to the inner side of each horizontal ring 2. One end of the spring 15 is fixedly connected to a limiting block 16. The outer side of the limiting block 16 is slidably connected to the inner side of the transverse ring 2. One side of the limiting block 16 is engaged with the outer side of the rotating block 10. The other side of the transverse ring 2 is fixedly connected to a locking block 12. Two insertion holes 13 are opened on the outer side of the locking block 12. The inner side of the insertion hole 13 is engaged with the outer side of the insertion rod 7. Multiple slots 14 are opened on the outer side of the locking block 12. The inner side of the slots 14 is engaged with the outer side of the pad 4. A buffer mechanism is provided on the outer side of the transverse ring 2. The slots 11 and the locking block 12 on one side of the two transverse rings 2 are spliced in opposite directions. The corresponding two insertion rods 7 are used to engage the slots 13 and the insertion holes 13 to keep the two transverse rings 2 connected stably. At the same time, the spring 15 and the limiting block 16 keep the connection between the inner thread 11 and the outer thread 9 on the inner side of the rotating block 10 stable, and prevent the rotating block 10 from becoming loose.
[0024] Reference Figure 3 and Figure 4 As shown, the buffer mechanism includes multiple graphite strips 17. The outer side of the graphite strips 17 is fixedly connected to the outer side of the horizontal ring 2. The graphite strips 17 are arranged in a ring array on the outer side of the horizontal ring 2. Two outer shells 18 are fixedly connected to the inner side of the two horizontal rings 2. The inner side of the outer shell 18 is rotatably connected to a limiting ball 19. A rotating ring 20 is rotatably connected to the outer side of the horizontal ring 2. The graphite strips 17 are used to lubricate the outer side of the horizontal ring 2. At the same time, the rotating ring 20 is used to rotate and rub the vertical ring 1 and the horizontal ring 2, so that the corresponding limiting ball 19 keeps the position of the vertical ring 1 on the inner side of the horizontal ring 2 stable.
[0025] The working principle of this utility model is as follows: When assembling the compact chain, a horizontal ring 2 is inserted between two vertical rings 1. Then, the rotating ring 20 on one side of the horizontal ring 2 is brought closer to the inside of the vertical ring 1. Next, the slot 3 on one side of one horizontal ring 2 is aligned and spliced with the block 12 on the other side of the horizontal ring 2, so that the two slots 3 and the block 12 are spliced and fitted together. Then, multiple pads 4 are engaged with multiple slots 14 on the outside of the block 12. Finally, the corresponding rotating block 6 and insert rod 7 are inserted into the horizontal ring. Inside the ring 2 and the insertion hole 13, the two guide blocks 8 on the outside of the rotating block 1 6 slide and limit the movement inside the slide groove 5. Then, the internal thread 11 on the inside of the rotating block 2 10 is threaded to the external thread 9 at one end of the insertion rod 7. After the internal thread 11 and the external thread 9 are screwed together, the spring 15 on the inside of the horizontal ring 2 pushes the limiting block 16 to limit the top of the rotating block 2 10, so that the rotating block 2 10 is snapped by the corresponding limiting block 16. Then, the upright ring 1 and the horizontal ring 2 are repeatedly spliced and assembled.
[0026] Then, during the use of the compact chain, multiple graphite strips 17 on the outer side of the horizontal ring 2 lubricate the inner side of the vertical ring 1. At the same time, during the load-bearing process of the compact chain, the swivel ring 20 on the outer side of the horizontal ring 2 slides and limits the inner side of the vertical ring 1, thereby reducing the contact between the vertical ring 1 and the horizontal ring 2. Meanwhile, the limiting ball 19 on the inner side of the outer shell 18 limits the horizontal ring 2 on both sides of the vertical ring 1, so that the multiple vertical rings 1 and the horizontal ring 2 maintain their durability.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
