Description

Technical Field

[0001] This utility model belongs to the technical field of overlapping devices, specifically an overlapping device for scraper conveyor chains. Background Technology

[0002] Scraper conveyors are widely used in industrial production due to their strong ash conveying capacity, high structural strength, and high load-bearing capacity. However, during the conveying of fine ash, the high-temperature particles and powdery materials cause pollution and severe wear to the chain itself, requiring regular chain inspection and replacement of damaged parts.

[0003] After the damaged section is removed using a chain remover, the chain becomes loose. Typically, a fixed frame is used, along with a rotating structure consisting of a double-threaded rod on the inner wall of the frame and limiting plates threaded to both ends of the double-threaded rod. This tensions the broken ends of the chain by passing the limiting plates through the gaps in the chain wheels and rotating the double-threaded rod. The two limiting plates bring the separated chain ends closer together and tighten them. However, after tightening the chain, the lack of a reliable limiting mechanism means the device is prone to detaching from the chain due to shaking during operation, leading to a loss of traction and affecting the efficiency of chain splicing and replacement. Therefore, to address these issues, a scraper conveyor chain splicing device is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a scraper conveyor chain splicing device is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The scraper conveyor chain overlapping device of this utility model includes a positioning plate; an adjustment groove is provided on one side of the positioning plate, a double-headed threaded rod is rotatably connected to the inner wall of the adjustment groove, one end of the double-headed threaded rod passes through the positioning plate and communicates with the outside, and limit plates are bolted to both ends of the outer wall of the double-headed threaded rod, and a fixing groove is provided on the inner wall of the adjustment groove.

[0006] The limiting plate is provided with a limiting mechanism, which includes a positioning groove on one side of the limiting plate, a limiting block slidably connected in the positioning groove, a stop block fixedly connected to one side of the limiting block, a through groove communicating with the positioning groove on one side of the limiting plate, a pressing block slidably connected in the positioning groove, a magnetic block fixedly connected to the top of the pressing block, and a second magnetic block fixedly connected to the inner wall of the positioning groove. Through the setting of the limiting mechanism, in conjunction with the double-ended threaded rod and the positioning plate, the movement of the limiting plate can be limited while the chain is tightened, preventing the device from detaching from the chain due to shaking during replacement, thus avoiding traction failure of the chain and affecting the chain's overlapping and replacement.

[0007] Preferably, a gripping rod is fixedly connected to one side of the positioning plate, and a gripping block is fixedly connected to one side of the outer wall of the gripping rod. By setting the gripping rod and the gripping block, the positioning plate and the double-ended threaded rod can be operated more conveniently by holding the gripping block or the gripping rod by hand.

[0008] Preferably, a baffle plate is fixedly connected to the outer wall of the limiting plate, and a baffle frame is fixedly connected to the side of the positioning plate near the limiting plate. By setting the baffle plate and the baffle frame, the exposed adjustment groove can be covered to prevent iron filings and dust on the chain from entering the adjustment groove and affecting the movement of the limiting plate.

[0009] Preferably, an inclined block is fixedly connected to one side of the limiting plate, and the other end of the inclined block is fixedly connected to the top of the baffle plate. The inclined block helps to support the limiting plate and reduce the pressure on the limiting plate.

[0010] Preferably, a knob is fixedly connected to one end of the double-ended threaded rod located on the outside. The outer wall of the knob is provided with anti-slip texture. The double-ended threaded rod can be rotated by rotating the knob. At the same time, the knob can be used to block the point where the double-ended threaded rod passes through the positioning plate, so as to prevent dust from entering the positioning groove from the point of penetration.

[0011] Preferably, a protective block is fixedly connected to one side of the positioning plate near the knob, and a protective groove is provided on one side of the protective block near the positioning plate. The protective block and the protective groove can be used to shield and protect the knob, preventing the positioning plate from touching and turning the knob when it comes into contact with the chain.

[0012] Preferably, the outer wall of the limiting plate is provided with a wear-resistant layer to improve wear resistance and service life, and the inner side wall of the through groove is provided with a sealing gasket to improve sealing performance.

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

[0014] This utility model provides a chain splicing device for scraper conveyors. Through the setting of a limiting mechanism, combined with a double-headed threaded rod and a positioning plate, the device can simultaneously tighten the chain and limit the movement of the limiting plate. This prevents the device from detaching from the chain due to shaking during replacement, thus avoiding traction failure and affecting the chain splicing and replacement. Using a chain remover, the damaged section of the chain is removed. The two limiting plates are passed through the gaps between the chain rollers. By reversing the knob, the two loose chain sections gradually approach and tighten. One end of the limiting block moves out of the slot and connects to the outside. The protruding limiting block limits the limiting plate to the chain, preventing it from detaching. For replacing the new chain, slowly reverse the knob to allow the new chain to naturally tighten, pulling the positioning plate away from the chain and releasing the movement limitation on the limiting plate.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a scraper conveyor chain splicing device, including a rectangular positioning plate 1. A cylindrical gripping rod 7 is fixedly connected to one side of the positioning plate 1. Two rectangular gripping blocks are fixedly connected to one side of the outer wall of the gripping rod 7. By setting the gripping rod 7 and the gripping blocks, the positioning plate 1 and the double-headed threaded rod 3 can be operated more conveniently by holding the gripping blocks or the gripping rod 7 by hand.

[0025] A rectangular adjustment groove 2 is provided on one side of the positioning plate 1. A double-threaded rod 3 is rotatably connected to the inner wall of the adjustment groove 2. One end of the double-threaded rod 3 passes through the positioning plate 1 and communicates with the outside. Both ends of the outer wall of the double-threaded rod 3 are bolted to rectangular limiting plates 4. Two symmetrically distributed conical fixing grooves 5 are provided on the inner wall of the adjustment groove 2.

[0026] A baffle plate 8 is fixedly connected to the outer wall of the limiting plate 4. A fitting groove adapted to the limiting plate 4 is opened on one side of the baffle plate 8 so that the baffle plate 8 is fixed to the outside of the limiting plate 4. A U-shaped baffle frame 9 is fixedly connected to the side of the positioning plate 1 near the limiting plate 4. The baffle frame 9 is centrally located on the positioning plate 1 and is adapted to the baffle plate 8. One end of the baffle plate 8 is inserted into the baffle frame 9. Through the setting of the baffle plate 8 and the baffle frame 9, the exposed adjustment groove 2 can be covered to prevent iron filings and dust on the chain from entering the adjustment groove 2 and affecting the movement of the limiting plate 4.

[0027] An inclined block 10 is fixedly connected to one side of the limiting plate 4, and the other end of the inclined block 10 is fixedly connected to the top of the baffle plate 8. The inclined block 10 is used to assist in supporting the limiting plate 4 and reduce the pressure on the limiting plate 4.

[0028] A knob 11 is fixedly connected to one end of the double-threaded rod 3 located on the outside. The outer wall of the knob 11 is provided with anti-slip texture. The double-threaded rod 3 can be rotated by rotating the knob 11. At the same time, the knob 11 blocks the point where the double-threaded rod 3 passes through the positioning plate 1, preventing dust from entering the positioning groove 61 from the point of penetration. A protective block 12 is fixedly connected to the side of the positioning plate 1 near the knob 11. A protective groove is opened on the side of the protective block 12 near the positioning plate 1. The setting of the protective block 12 and the protective groove can easily block and protect the knob 11, preventing the positioning plate 1 from touching and turning the knob 11 during contact with the chain.

[0029] The outer wall of the limiting plate 4 is provided with a wear-resistant layer to improve wear resistance and service life, and the inner wall of the through groove 64 is provided with a sealing gasket to improve sealing performance.

[0030] A limiting mechanism 6 is provided on the limiting plate 4. The limiting mechanism 6 includes a positioning groove 61 opened on one side of the limiting plate 4. A limiting block 62 is slidably connected in the positioning groove 61. A rectangular stop block 63 is fixedly connected to one side of the limiting block 62. A rectangular through groove 64 connected to the positioning groove 61 is opened on one side of the limiting plate 4. Both ends of the limiting block 62 are set as cones. A pressing block 65 is slidably connected in the positioning groove 61. A first magnetic block 66 is fixedly connected to the top of the pressing block 65. The first magnetic block 66 is located at the end of the pressing block 65 near the limiting block 62. A second magnetic block 67 is fixedly connected to the inner wall of the positioning groove 61. The first magnetic block 66 and the second magnetic block 67 are arranged opposite to each other, and the opposite sides of the first magnetic block 66 and the second magnetic block 67 are set as the same level, so that there is a repulsive force between them.

[0031] By setting the limiting mechanism 6, together with the double-headed threaded rod 3 and the positioning plate 1, the movement of the limiting plate 4 can be limited at the same time as the chain is tightened. This prevents the device from detaching from the chain due to shaking during the replacement process, which would cause the chain to lose its traction and affect the chain's overlapping replacement.

[0032] Based on the above structure, the present invention includes the following implementation process:

[0033] Rotating the knob 11 drives the double-ended threaded rod 3 to rotate. The rotation of the double-ended threaded rod 3 drives the two limiting plates 4 to move away from each other, so that the fixing groove 5 and the positioning groove 61 are opposite each other. Under the action of the repulsive force between the first magnetic block 66 and the second magnetic block 67, the pressing block 65 moves away from the limiting block 62, and the end of the pressing block 65 away from the first magnetic block 66 is inserted into the fixing groove 5.

[0034] When a section of the chain of the scraper conveyor is damaged, open the conveyor to expose the damaged section of the chain, use a chain remover to remove the damaged section. At this time, the chain is loose. Position the positioning plate 1 opposite the damaged section of the chain, and pass the two limit plates 4 through the gap between the rollers of the chain. Turn the knob 11 in reverse so that the two limit plates 4 gradually move closer, so that the two loose sections of the chain gradually move closer and tighten, and lock the chain position to prevent tension rebound.

[0035] As the two limiting plates 4 approach each other, the limiting plates 4 simultaneously drive the pressing block 65 to move. The bottom end of the pressing block 65 gradually moves out of the conical fixing groove 5 into the adjusting groove 2. The pressing block 65 drives the first magnetic block 66 to move towards the second magnetic block 67. The top of the pressing block 65 applies pressure to the limiting block 62, causing one end of the limiting block 62 to move out of the through groove 64 and connect with the outside. The protruding limiting block 62 limits the limiting plate 4 to the chain, preventing the limiting plate 4 from detaching from the chain.

[0036] The replacement chain can then be installed between the two chain sections, aligning the chain links at both ends to ensure precise alignment of the connecting holes. Insert the new chain shaft and tighten the lock nut. During the process, keep the hydraulic auxiliary tightening device working to prevent the chain from shifting. Remove the quick-release positioning pin and the hydraulic auxiliary tightening device.

[0037] Slowly reverse knob 11 to make the two limiting plates 4 move away from each other slowly, allowing the new chain to naturally tension. Observe whether the chain and sprocket mesh smoothly without jamming. When the fixed groove 5 and the positioning groove 61 are opposite each other, under the action of the repulsive force between the first magnetic block 66 and the second magnetic block 67, the pressing block 65 moves away from the limiting block 62, and the end of the pressing block 65 away from the first magnetic block 66 is inserted into the fixed groove 5. At this time, the positioning plate 1 can be pulled away from the chain. At this time, the conical end of the limiting block 62 located on the outside is pressed and automatically retracts into the positioning groove 61, releasing the movement limitation of the limiting plate 4. The limiting plate 4 can then be pulled out from the gap between the chain and the wheel.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
