Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to a scraper conveyor anti-deviation device. Background Technology

[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials within a trough. Scraper conveyors are essential transportation tools used in coal mines, chemical mines, metal mines, and power plants. They offer advantages such as unaffected transport capacity by the particle size and moisture content of the load, high machine strength, and flexibility. However, the transport method of a scraper conveyor involves both the material and the scraper chain sliding within the trough, resulting in significant operating resistance and wear.

[0003] For example, patent CN223315737U discloses a scraper conveyor, which relates to the field of material conveying technology. It includes a head section, a tail section, a middle section body, and a scraper chain assembly. The head section is equipped with a motor, a gearbox, and a drive sprocket. The motor output is connected to the gearbox input via a coupling, and the gearbox output is connected to the drive sprocket. The scraper chain assembly includes scrapers and a ring chain. The middle part of the scraper is connected to the ring chain, and multiple scrapers are provided, with equal spacing between them. The drive sprocket meshes with the ring chain. The tail section is equipped with a tensioning assembly, which includes a follower sprocket, a spring, a sprocket sliding seat, and a chute plate. The follower sprocket meshes with the ring chain, and its shaft is mounted on the sprocket sliding seat. The tail section is equipped with a chute plate, and the spring is located between the tail frame and the sprocket sliding seat. The middle section body is a long trough shape with a discharge port located at the bottom. The scrapers have scraper tongues, which are L-shaped with the scrapers. The scraper conveyor of this invention is simple to maintain and not prone to failure.

[0004] However, the aforementioned scraper conveyor relies solely on tensioning components to indirectly ensure chain stability, without a dedicated limiting and guiding structure for the scraper. Furthermore, in this patent, the scraper is connected to the chain via the middle section. When the scraper moves with the chain, if the chain shifts laterally due to uneven conveying resistance or slight deformation of the machine body, the scraper is prone to deviating from the set conveying path, resulting in friction and collision with the trough wall of the middle section of the machine body. This not only exacerbates the wear between the scraper and the trough wall but may also cause scraper deformation and chain jamming, affecting the continuity of conveying. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper anti-deviation device for scraper conveyors, so as to solve the problem mentioned in the background art that the lack of a dedicated limiting and guiding structure for scrapers leads to lateral deviation of the chain due to uneven conveying resistance, slight deformation of the machine body, etc., which causes the scraper to deviate from the set conveying path and then rub against and collide with the middle section of the machine body trough wall, aggravating the wear of the scraper and the trough wall, and may also cause scraper deformation, chain jamming, and affect the continuity of conveying.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A scraper conveyor anti-deviation device includes: two sets of connecting plates, with transmission columns rotatably installed at both ends between the two sets of connecting plates, and sprockets fixedly installed at both ends of the outer surfaces of the two sets of transmission columns, and an anti-deviation mechanism is fitted onto the outer surfaces of each pair of laterally opposite sprockets.

[0008] Preferably, a bearing plate is fixedly installed between the two sets of connecting plates and simultaneously positioned between the two sets of transmission columns. The two ends of the bearing plate slide against the outer surfaces of the two sets of transmission columns. The outer and upper and lower surfaces of the two sets of transmission columns and the bearing plate are all embedded with guide rail grooves and are connected to each other. The anti-deviation mechanism rolls inside the guide rail grooves.

[0009] Preferably, the anti-deviation mechanism includes two sets of chains, which are respectively meshed and fitted on the outer surfaces of two sets of sprockets that are laterally opposite. Multiple sets of connecting discs are fixedly installed at equal intervals on one inner end of the two sets of chains. A connecting rod is rotatably installed between each pair of longitudinally opposite connecting discs on the two sets of chains, and a scraper is fixedly installed on the upper end of the outer surface of the connecting rod.

[0010] Preferably, both sets of chains are enclosed by an extension ring cover, which is fixedly installed on one end of the inner side of the connecting plate.

[0011] Preferably, a Y-shaped frame is fixedly installed on both sides of the lower end of the outer surface of each set of connecting rods, and a guide wheel is rotatably installed in each of the two sets of branch rods of the Y-shaped frame, and the guide wheel rolls in the guide groove.

[0012] Preferably, when the scraper is driven by the chain, it can rotate synchronously in the guide groove through two sets of guide wheels rotatably mounted on the Y-shaped frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By precisely matching the guide wheel and guide groove, the chain and scraper are tracked and limited, effectively preventing the scraper from deviating laterally. At the same time, the extended ring cover protects the chain from interference by debris. This ensures that the scraper can stably transport materials along the set path, reduce transport interruptions and material loss, reduce component wear and maintenance frequency, thereby improving material transport efficiency while reducing equipment operation and maintenance costs.

[0019] 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.

[0020] Please see Figures 1-3 This embodiment provides the following technical solution:

[0021] like Figures 1-2 As shown, a scraper conveyor anti-deviation device includes: two sets of connecting plates 1, with transmission columns 101 rotatably installed at both ends between the two sets of connecting plates 1, and sprockets 105 fixedly installed at both ends of the outer surfaces of the two sets of transmission columns 101, and anti-deviation mechanism 2 meshing on the outer surfaces of each pair of laterally opposite sprockets 105.

[0022] Among them, a bearing plate 102 is fixedly installed between the two sets of connecting plates 1 and is located between the two sets of transmission columns 101. The two ends of the bearing plate 102 slide against the outer surface of the two sets of transmission columns 101. The outer and upper and lower surfaces of the two sets of transmission columns 101 and the bearing plate 102 are all embedded with guide rail grooves 103 and are connected to each other. The anti-deviation mechanism 2 rolls inside the guide rail grooves 103.

[0023] Through the design of the transmission column 101, bearing plate 102, guide rail groove 103, sprocket 105, and anti-deviation mechanism 2, during operation, the transmission column 101 can be driven to rotate by a motor. Since the sprockets 105 at both ends of the outer surface of the two sets of transmission columns 101 mesh with the anti-deviation mechanism 2, the rotation of the transmission column 101 will drive the anti-deviation mechanism 2 to move along the meshing trajectory of the sprockets 105, thereby realizing the cyclic transmission of the anti-deviation mechanism 2. At the same time, because the bearing plate 102 is fixedly installed between the two sets of connecting plates 1 and between the two sets of transmission columns 101, Both ends of the device slide against the outer surface of the transmission column 101, and the outer and upper and lower surfaces of the transmission column 101 and the bearing plate 102 are provided with interlocking embedded guide rail grooves 103. During the movement of the anti-deviation mechanism 2 with the sprocket 105, it will always roll in the guide rail groove 103. The guide rail groove 103 forms a limit constraint on the movement trajectory of the anti-deviation mechanism 2, so as to prevent the anti-deviation mechanism 2 from lateral deviation during the transmission process, thereby ensuring that the anti-deviation mechanism 2 can stably drive the scraper 204 to run along the set path and realize normal material conveying.

[0024] like Figure 3 As shown, the anti-deviation mechanism 2 includes two sets of chains 201. The two sets of chains 201 are respectively meshed and fitted on the outer surfaces of two sets of sprockets 105 that are laterally opposite. Multiple sets of connecting discs 202 are fixedly installed at equal intervals on one inner end of the two sets of chains 201. A connecting rod 203 is rotatably installed between each pair of longitudinally opposite connecting discs 202 on the two sets of chains 201. A scraper 204 is fixedly installed on the upper end of the outer surface of the connecting rod 203.

[0025] Both sets of chains 201 are enclosed by extension ring covers 104, which are fixedly installed on one end of the inner side of the connecting plate 1. Y-shaped frames 205 are fixedly installed on both sides of the lower outer surface of each connecting rod 203. Guide wheels 206 are rotatably installed within the two sets of branch rods of the Y-shaped frame 205, and these guide wheels 206 rotate within the guide groove 103. When the scraper 204 is driven by the chains 201, it can rotate synchronously within the guide groove 103 via the two sets of guide wheels 206 rotatably installed on the Y-shaped frame 205.

[0026] Through the design of chain 201, connecting disc 202, connecting rod 203, scraper 204, Y-shaped frame 205, and guide wheel 206, when the device is running, the transmission column 101 drives the sprocket 105 to rotate, and the two sets of chains 201 meshing with the sprocket 105 are synchronously driven. The connecting discs 202, which are equidistantly fixed on the inner side of the chain 201, drive the connecting rod 203, which is rotatably installed between the longitudinally opposite connecting discs 202, to move. This causes the scraper 204, which is fixed at the upper end of the connecting rod 203, to convey materials with the transmission of the chain 201. At the same time, the scraper 204, which is fixed on both sides of the lower end of the connecting rod 203, is also conveyed. The Y-shaped frame 205 moves synchronously with the connecting rod 203. The guide wheel 206, which is rotatably installed inside the branch rod of the Y-shaped frame 205, rolls in the guide groove 103. Through the cooperation between the guide wheel 206 and the guide groove 103, the movement trajectory of the chain 201 and the scraper 204 is precisely limited, preventing the chain 201 from deviating laterally during transmission. This ensures that the scraper 204 always runs stably along the set path, preventing the scraper 204 from colliding or rubbing against other parts of the device. It also ensures that the scraper 204 always transports materials stably along the set path, reducing the problem of conveying interruption caused by deviation.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: During operation, the transmission column 101 can be rotated by a motor. Since the sprockets 105 at both ends of the outer surface of the two sets of transmission columns 101 mesh with the chain 201, the two sets of chains 201 will be synchronously transmitted. The connecting discs 202 fixed at equal intervals on the inner side of the chain 201 will drive the connecting rods 203 that are rotatably installed between the longitudinally opposite connecting discs 202 to move. This causes the scraper 204 fixed at the upper end of the connecting rod 203 to convey materials with the transmission of the chain 201. At the same time, the scraper 204 fixed at the lower end of the connecting rod 203 will move. The fixed Y-shaped frame 205 moves synchronously with the connecting rod 203. The guide wheel 206, which is rotatably installed in the branch rod of the Y-shaped frame 205, rolls in the guide groove 103. Through the cooperation between the guide wheel 206 and the guide groove 103, the movement trajectory of the chain 201 and the scraper 204 is precisely limited, so as to prevent the chain 201 from deviating laterally during the transmission process and ensure that the scraper 204 always runs stably along the set path. The extended ring cover 104 protects the chain 201 and prevents external debris from interfering with the normal transmission of the chain 201, thus achieving the anti-deviation effect of the scraper 204.

[0028] In summary: By having the guide wheel 206 on the Y-shaped frame 205 engage and roll within the guide groove 103, the movement trajectory of the chain 201 and scraper 204 is strictly limited, effectively preventing the chain 201 from shifting laterally and preventing the scraper 204 from colliding or jamming with other components of the device due to deviation. This ensures that the scraper 204 always transports materials stably along the set path, reduces conveying interruptions caused by deviation, and guarantees the continuity of material conveying.
