Abstract
Description
Technical Field
[0001] This invention relates to the field of scraper conveyor technology, specifically to a scraper conveyor circular chain structure with a tension detection mechanism. Background Technology
[0002] As a key piece of equipment in coal mining and transportation, scraper conveyors play a vital role in material transport within the mine production system. In the three-machine setup of large-scale fully mechanized mining, the transfer conveyor, a special type of scraper conveyor, connects at one end to the conveyor at the working face and at the other end to the tail of the belt conveyor. It is responsible for transferring the coal transported by the scraper conveyor at the mining face from the roadway floor to the belt conveyor, playing a crucial role in connecting and transitioning the entire coal transportation process.
[0003] However, most scraper conveyors rely on the combination of spring chains and sprockets to drive the scraper and push material. Most existing sprockets are integrally cast, requiring disassembly and maintenance after prolonged use. This process is inconvenient, time-consuming, labor-intensive, and costly. Furthermore, the width of most current scraper conveyors is not adjustable, hindering installation based on available space. This makes it difficult to adjust the conveyor's capacity and reduce conveying capacity. With a fixed width, increased material load leads to excessive material accumulation, increasing the load and reducing the conveyor's lifespan. Additionally, the conveyor chain faces issues like uneven tension and wear during long-term high-intensity operation. Measuring chain tension on-site requires manual labor, a cumbersome process that lacks real-time monitoring and adjustment capabilities, ultimately damaging the chain. Moreover, underground operation generates significant dust, which, if not properly managed, can cause environmental pollution. Summary of the Invention

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0039] like Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, the scraper conveyor circular chain structure with tension detection mechanism of the present invention includes a housing 1, two symmetrically interlocked housings 1 on which a conveying mechanism 2 is installed, a connecting mechanism 3 is installed on the conveying mechanism 2, a supporting mechanism 4 is installed on the housing 1, a detection mechanism 5 is installed on the supporting mechanism 4, an adjusting mechanism 6 is installed on the housing 1, and a telescopic mechanism 7 is installed on the housing 1.
[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying mechanism 2 includes a rotating shaft 201. Two rotating shafts 201 are rotatably connected between two symmetrical outer shells 1. Gear discs 204 are respectively mounted at the ends of the two rotating shafts 201. Multiple toothed blocks 205 arranged in a ring at equal intervals are mounted on the outer wall of each toothed disc 204. The two toothed discs 204 are connected by a chain 206. The chain 206 engages with the toothed discs 204 through the multiple toothed blocks 205. The two chains 206 are rotatably connected to the inner sides of the two outer shells 1 through two sets of toothed discs 204. Scrapers 202 are detachably connected to the two chains 206 via connectors 203. The multiple scrapers 202 are connected to the outer shells via the chains 206. The internal sliding connection is achieved by assembling two symmetrical outer shells 1 to form a trough structure for material placement. The installation of two rotating shafts 201 facilitates the installation of two sets of toothed discs 204. With the cooperation of multiple toothed blocks 205, two parallel chains 206 are connected. The installation of the chains 206 enables synchronous drive control of multiple scrapers 202. A motor is connected to the end of the rotating shaft 201, and the motor drives the rotating shaft 201, thereby causing the two chains 206 to drive the multiple scrapers 202 to move synchronously, thus pushing and conveying the material stored inside the outer shell 1.
[0041] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 11 As shown, the outer shell 1 has an "L" shaped cross-section, and the two symmetrical outer shells 1 form a "U" shaped structure. The toothed block 205 has a "T" shaped structure, which facilitates the formation of a groove structure after the outer shells 1 are spliced together, enabling the material to be placed and pushed. It also facilitates the subsequent adjustment of the width of the two outer shells 1, and allows the toothed block 205 to drive the chain 206.
[0042] Specifically, such as Figure 4 and Figure 5 As shown, the connecting mechanism 3 includes a slot 301. The outer walls of the two sets of gear discs 204 are provided with multiple slots 301 distributed in an annular pattern. The bottom of the tooth block 205 engages with the inside of the slot 301. The tooth block 205 is detachably connected to the gear disc 204 by two screws 302. The slots 301 facilitate the stable engagement of the tooth block 205 and the gear disc 204, preventing loosening and slippage, and thus providing a positioning function. The screws 302 facilitate the detachable installation and disassembly of the tooth block 205 and the gear disc 204, making subsequent disassembly and maintenance more convenient, saving costs and improving maintenance efficiency.
[0043] Specifically, such as Figure 4 , Figure 5 and Figure 6 As shown, the gear disc 204 has multiple sets of symmetrical locking grooves 303 inside. The opposite ends of the locking grooves 303 are connected to the slots 301. The bottom ends of the gear block 205 are respectively equipped with locking blocks 304. The locking blocks 304 are slidably connected to the inside of the gear block 205 through a return spring 306. One end of the locking block 304 extends to the outside of the gear block 205 and engages with the inside of the locking groove 303. The opposite ends of the symmetrical locking blocks 304 are respectively vertically connected with push rods 305. The push rods 305 pass through the return spring 306 and abut against the outside of the screw 302. One end of the push rod 305 has a hemispherical structure. The push rod 305 is connected to the gear block through the locking blocks 304. The toothed block 205 is internally slidably connected. Two screws 302 fasten the toothed block 205, causing one end of the push rod 305 to be pressed. The push rod 305 drives the locking block 304 to slide free from the elastic force of the return spring 306. The locking block 304 engages internally with the locking groove 303, limiting the toothed block 205 and the toothed disc 204, increasing the fastening effect and reducing wear on the screws 302 during operation. By removing the screws 302, the push rod 305 is not subjected to external force, and the locking block 304 resets under the pull of the return spring 306, facilitating the disassembly of the toothed block 205.
[0044] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 11 , Figure 12 and Figure 13As shown, the telescopic mechanism 7 includes a fixed plate 701. The two outer shells 1 are connected by the fixed plate 701. The two outer shells 1 are slidably connected to both sides of the fixed plate 701 via a sliding groove 706. Multiple bases 703 are installed at the bottom of both ends of the fixed plate 701. Support blocks 708 are slidably connected to the top ends of the multiple bases 703. The tops of the two support blocks 708 are connected to the bottoms of the two outer shells 1. The two outer shells 1 are slidably connected to the tops of the bases 703 via the support blocks 708. The two scrapers 202 are slidably connected by a connecting plate 702. The rotating shaft 201 is divided into two sections by a connecting sleeve 705. The two ends of the rotating shaft 201 are slidably connected to the connecting sleeve 705. One end of the rotating shaft 201 has a hexagonal structure and is connected to the fixed plate 706 via the fixed plate 701. With the installation of 1, and in cooperation with the slide groove 706, the two outer shells 1 are slidably connected to both sides of the fixing plate 701, so that the width of the two outer shells 1 can be adjusted without material leakage. Thus, the width can be adjusted according to the site position, and the conveying volume and the type of conveyed material can also be changed as needed. The installation of the base 703 supports and fixes the fixing plate 701. The sliding of the support block 708 enables the outer shell 1 to slide stably. The installation of the connecting plate 702 and the connecting sleeve 705 enables the multiple scrapers 202 to adjust their width along with the outer shell 1. The rotating shaft 201 can adjust its length, ensuring that when the outer shell 1 is adjusted, the two chains 206 also adjust their positions accordingly.
[0045] Specifically, such as Figure 1 , Figure 12 and Figure 13 As shown, anti-slip pads 704 are installed at the bottom of both ends of the base 703. Multiple second hydraulic cylinders 709 are installed inside both ends of the base 703. One end of each second hydraulic cylinder 709 is fixed to a support block 708, and the other end is fixed to the inner side of the base 703. Multiple connecting plates 702 have multiple connecting springs 707 installed inside both ends. The ends of the connecting springs 707 are connected to the ends of scrapers 202. The scrapers 202 are slidably connected to the inner ends of the connecting plates 702 via the multiple connecting springs 707. With the installation of the anti-slip pads 704, the base 703 is stable when placed on the ground. Furthermore, the synchronous operation of the multiple sets of second hydraulic cylinders 709 enables the second hydraulic cylinders 709 to synchronously drive the two support blocks 708 to move, allowing the two outer shells 1 to move away or closer synchronously, thereby changing their width. The connecting springs 707 cooperate to connect the scrapers 202, preventing them from detaching.
[0046] Specifically, such as Figure 1 , Figure 7 and Figure 8As shown, the support mechanism 4 includes a through groove 401. Multiple through grooves 401 are provided on the side walls of the two outer shells 1. A fixing block 403 is fixedly connected to the outer walls of the two outer shells 1. A connecting block 405 is slidably connected to the top of the fixing block 403 via a compression spring 404. A guide rod 406 is installed at the bottom of the connecting block 405. The guide rod 406 passes through the compression spring 404 and is slidably connected to the inside of the fixing block 403. A support roller 402 is rotatably connected to one side of the connecting block 405. One end of the support roller 402 extends into the through groove 401, and one end of the support roller 402 abuts against the bottom of the chain 206. The fixing block 405... The installation of 3 provides support for the connecting block 405. The installation of the compression spring 404 and the guide rod 406 facilitates stable support for the connecting block 405. The connecting block 405 has telescopic sliding with the outer side of the outer shell 1, and the support roller 402 can always maintain contact with the chain 206. Through the contact between the support roller 402 and the chain 206, the tension of the chain 206 can be transmitted to the support roller 402 in real time. The support roller 402 can drive the connecting block 405 to move away from the elastic force of the compression spring 404, which facilitates subsequent detection of the movement position and thus the measurement of the tension.
[0047] Specifically, such as Figure 7 , Figure 8 and Figure 9 As shown, the detection mechanism 5 includes a drive rod 501, which is rotatably connected to the outside of the connecting block 405. A slide rod 506 is slidably connected to one end of the fixed block 403, and a slider 502 is mounted on one end of the slide rod 506. One end of the drive rod 501 is rotatably connected to one side of the slider 502, with an angle of 30 degrees between the drive rod 501 and the slider 502. A proximity sensor 504 is installed at the center of the fixed block 403, and the other end of the slide rod 506 is located at one end of the proximity sensor 504. Through the cooperation of the slide rod 506, the slider 502... The connecting block 405 can slide on one end of the fixed block 403. Through the installation of the drive rod 501, the sliding block 405 can control the sliding of the slider 502 and the sliding rod 506 when it moves. Through the operation of the proximity sensor 504, the sliding position of the sliding rod 506 can be detected. The tension change of the chain 206 can be determined by the sliding position of the sliding rod 506. Through the connection of the proximity sensor 504 with an external controller, data processing and analysis can be realized, which is beneficial for subsequent control of the first hydraulic cylinder 601 to adjust the tension of the chain 206.
[0048] Specifically, such as Figure 8 and Figure 9As shown, a movable groove 503 is provided on one side of the fixed block 403, and a sliding plate 507 is slidably connected inside the movable groove 503. One end of the sliding plate 507 is perpendicularly connected to the outside of the sliding rod 506. The sliding plate 507 has a "T"-shaped structure, and the other end of the sliding plate 507 extends to the outside of the fixed block 403. A scale 505 is provided on the outside of the fixed block 403. The movable groove 503 facilitates the installation of the sliding plate 507. The installation of the sliding plate 507 and the sliding rod 506 allows the sliding rod 506 to slide, thereby driving the sliding plate 507 to move. With the cooperation of the scale 505, the tension can be observed on-site, preventing the inability to know the tension when the proximity sensor 504 is damaged.
[0049] Specifically, such as Figure 1 and Figure 10 As shown, the adjustment mechanism 6 includes a moving groove 606. The moving groove 606 is provided on the outer side of one end of each of the two outer shells 1. A slide block 602 is slidably connected to the moving groove 606. The end of the rotating shaft 201 is rotatably connected to the two symmetrical slide blocks 602. A fixed seat 604 is fixedly connected to the outer side of each of the two outer shells 1. A first hydraulic cylinder 601 is installed on one side of the fixed seat 604. The output shaft of the first hydraulic cylinder 601 is connected to the slide block 602. The opening of the moving groove 606 facilitates the sliding connection of the slide block 602. The synchronous drive of the first hydraulic cylinder 601 realizes the movement control of the two gear discs 204, which facilitates the tension adjustment of the two chains 206.
[0050] Specifically, such as Figure 10 As shown, two symmetrical slide blocks 602 are respectively equipped with baffles 603 on opposite sides. The baffles 603 are slidably connected to the inner wall of the outer casing 1. The output shaft of one end of the first hydraulic cylinder 601 is connected to the slide block 602 through a buffer spring 605. The installation of the baffles 603 helps to block the moving groove 606, preventing material from overflowing. The installation of the buffer spring 605 helps the slide block 602 to have a certain degree of flexibility when the first hydraulic cylinder 601 is working, preventing damage to the chain 206 caused by excessive tightening.
[0051] Specifically, such as Figure 1As shown, a dust removal mechanism 8 is installed on the outer shell 1. The dust removal mechanism 8 includes a fixing sleeve 802. The two outer shells 1 are respectively fixedly connected to the fixing sleeves 802. A connecting pipe 803 is installed on the fixing sleeve 802. An atomizing nozzle 804 is installed on the top of the connecting pipe 803. The bottoms of multiple connecting pipes 803 are connected to each other through a water inlet pipe 801. The installation of the fixing sleeve 802 facilitates the installation of the connecting pipe 803. The installation of the atomizing nozzle 804 facilitates the atomization of the water transported inside the water inlet pipe 801, so that the atomized water sprayed out can play a role in dust suppression.
[0052] In use, this invention first assembles two symmetrical outer shells 1 to form a trough-like structure for material placement. The installation of two rotating shafts 201 facilitates the installation of two sets of toothed discs 204. With the cooperation of multiple toothed blocks 205, two parallel chains 206 are connected. The installation of the chains 206 enables synchronous drive control of multiple scrapers 202. A motor is connected to the end of the rotating shaft 201, and the motor drives the rotating shaft 201, thereby causing the two chains 206 to drive the multiple scrapers 202 to move synchronously, pushing and conveying the material stored inside the outer shell 1. This facilitates the trough-like structure formed after the outer shells 1 are assembled, enabling the material to be placed and pushed. It also facilitates subsequent adjustment of the width of the two outer shells 1, allowing the toothed blocks 205 to... The chain 206 is driven by a slot 301 that facilitates stable engagement between the toothed block 205 and the toothed disc 204, preventing loosening and slippage, and providing positioning. The screw 302 allows for easy detachment and installation of the toothed block 205 and the toothed disc 204, making subsequent disassembly and maintenance more convenient, saving costs and improving maintenance efficiency. The two screws 302 tighten the toothed block 205, pressing one end of the push rod 305. The push rod 305 drives the locking block 304 to break free from the elastic force of the return spring 306, causing the locking block 304 to engage with the locking groove 303, thus limiting the position of the toothed block 205 and the toothed disc 204, increasing the tightening effect, and reducing wear on the screw 302 during operation. Removing the screw 302 eliminates external resistance to the push rod 305. The locking block 304 is reset under the pull of the return spring 306, facilitating the disassembly of the toothed block 205. Through the installation of the fixing plate 701, and with the cooperation of the sliding groove 706, the two outer shells 1 are slidably connected to both sides of the fixing plate 701, allowing the width of the two outer shells 1 to be adjusted without material leakage. This allows for width adjustment according to the site location, and also to change the conveying volume and the type of material being conveyed. The installation of the base 703 provides support and fixation for the fixing plate 701. The sliding of the support block 708 ensures stable sliding of the outer shells 1. The installation of the connecting plate 702 and the connecting sleeve 705 allows multiple scrapers 202 to also adjust their width along with the outer shells 1. The rotating shaft 201 can be adjusted in length, ensuring the safety of the outer shells. During adjustment, the two chains 206 also adjust their positions accordingly. The anti-slip pads 704 ensure stability when the base 703 is placed on the ground. Simultaneous operation of multiple sets of second hydraulic cylinders 709 drives the two support blocks 708 to move synchronously, allowing the two outer shells 1 to move closer or further apart, thus changing their width. The connecting spring 707 connects the scraper 202, preventing it from slipping. The fixing block 403 supports the connecting block 405. The compression spring 404 and guide rod 406 ensure stable support for the connecting block 405. The connecting block 405 has telescopic sliding capability with the outer side of the outer shell 1, and the support roller 402 always remains in contact with the chains 206.Through the contact between the support roller 402 and the chain 206, the tension of the chain 206 can be transmitted to the support roller 402 in real time. The support roller 402 can drive the connecting block 405 to move away from the elastic force of the compression spring 404, which facilitates subsequent detection of the movement position and thus the measurement of the tension. Through the cooperation of the slide rod 506, the slider 502 and one end of the fixed block 403 can slide. Through the installation of the drive rod 501, the movement of the connecting block 405 can control the sliding of the slider 502 and the slide rod 506. Through the operation of the proximity sensor 504, the sliding position of the slide rod 506 can be detected, and the tension change of the chain 206 can be judged by the sliding position of the slide rod 506. Through the connection of the proximity sensor 504 and the external controller, data processing and analysis can be realized, which is beneficial for subsequent control of the first hydraulic cylinder 601 to realize the tension adjustment of the chain 206. The opening of the movable groove 503 facilitates the installation of the slide plate 507. The installation of the slide bar 506 facilitates the movement of the slide plate 507 when the slide bar 506 slides. With the cooperation of the scale 505, the tension can be observed on-site, preventing the inability to know the tension if the proximity sensor 504 is damaged. The opening of the moving groove 606 facilitates the sliding connection of the slide block 602. Synchronous drive of the first hydraulic cylinder 601 enables movement control of the two toothed discs 204, facilitating tension adjustment of the two chains 206. The installation of the baffle 603 helps to block the moving groove 606, preventing material overflow. The installation of the buffer spring 605 ensures that the slide block 602 has a certain degree of flexibility when the first hydraulic cylinder 601 is working, preventing damage to the chains 206 due to excessive tightening. The installation of the fixing sleeve 802 facilitates the installation of the connecting pipe 803. The installation of the atomizing nozzle 804 facilitates the atomization of the water transported inside the water inlet pipe 801, allowing the atomized water to suppress dust.
