Detailed Implementation

[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] Please see Figures 1-6This utility model provides an accumulation-type conveyor chain drive device, including a conveyor chain drive device body 1. A positioning cylinder 2 is fixedly connected to the top surface of the support of the conveyor chain drive device body 1 by a pipe clamp. A corrugated pipe 3 is provided inside the positioning cylinder 2. A positioning plate 4 is fixedly connected to one end of the corrugated pipe 3. The positioning plate 4 is fixedly connected to one end of the positioning cylinder 2 by bolts. An oil inlet pipe 5 is installed on the surface of the positioning plate 4. An oil outlet pipe 6 is installed on the center surface of the positioning plate 4. A first pipe 7 is installed inside the oil outlet pipe 6. A second pipe 8 is fixedly connected to the end of the first pipe 7 away from the oil outlet pipe 6. An atomizing nozzle 9 is installed at the end of the second pipe 8 away from the first pipe 7. The atomizing nozzle 9 faces the chain position of the conveyor chain drive device body 1. A flexible hose 16 is provided between the first pipe 7 and the second pipe 8. The two ends of the flexible hose 16 are connected to the first pipe 7 and the second pipe 8. The second pipe 8 is connected. Before using the main body 1 of the conveyor chain drive device, oil is first injected into the bellows 3 through the oil inlet pipe 5 from an external oil tank. Then, when starting the main body 1 of the conveyor chain drive device, the valve of the oil drain pipe 6 is opened. The oil will enter the inside of the hose 16 through the first pipe 7, and then enter the inside of the second pipe 8. Then, it will be sprayed onto the chain through the atomizing nozzle 9. The atomizing nozzle 9 will atomize the oil to prevent it from splashing when it comes into contact with the chain due to its columnar shape. This achieves the application of lubricating oil to the chain and reduces the wear of the chain during use. In order to save oil, the hose 16 can be squeezed and deformed by pressing it, and the inner wall of the hose will shrink to stop the flow of oil. By regularly and intermittently squeezing the hose 16, the oil can be sprayed onto the chain intermittently, achieving lubrication while also saving oil to a certain extent.

[0024] It should be noted that the main body 1 of the conveyor chain drive device is an accumulation-type overhead conveyor, including a drive unit, a tensioning device, a carrying trolley including a front trolley, a middle trolley, a rear trolley, a connecting rod and a load beam, a traction chain (a detachable forged chain), a carriage, a track including accumulation track, traction rail and carrying rail, a turnout including a straight track turnout, a curved track turnout and a maintenance turnout, a horizontal slewing device including an accumulation track horizontal slewing device and a traction rail horizontal slewing device, a stopper, a backstop and a catcher, etc. When the workpiece needs to be paused, the lifting device descends to the buffer position, disengages from the drive chain, and the subsequent chain continues to run. When conveying resumes, the lifting device rises and re-engages the chain. It has the characteristics of not interfering with the main line operation and flexible accumulation position.

[0025] In this embodiment, a bearing seat 12 is fixedly connected to the support surface of the main body 1 of the conveyor chain drive device. A linkage plate 11 is rotatably connected inside the bearing seat 12. A force-applying plate 10 is provided at the bottom end of the linkage plate 11. A positioning groove is opened inside the force-applying plate 10. A positioning shaft is provided inside the positioning groove. The positioning shaft and the linkage plate 11 are fixedly connected. A connecting rod 13 is slidably connected to the end of the linkage plate 11 away from the positioning shaft. A pressing plate 14 is fixedly connected to the end of the connecting rod 13 away from the linkage plate 11. A connecting frame 15 is fixedly connected to the surface of the first pipe 7. The pressing plate 14 is inserted into the inside of the connecting frame 15. Two fixing plates 17 are symmetrically fixedly connected to the surface of the pressing plate 14. A first spring 18 is fixedly connected to the surface of the fixing plate 17. One end of a spring 18 away from the fixed plate 17 is fixedly connected to the connecting frame 15. To facilitate intermittent oil injection, when the chain moves, the connecting link will squeeze the force plate 10, which will move outward and exert force on the linkage plate 11. The linkage plate 11 rotates inside the bearing seat 12 due to the force, and at the same time, it will drive the extrusion plate 14 to move away from the hose 16 through the connecting rod 13. The first spring 18 will be squeezed and compressed by the fixed plate 17, and the extrusion plate 14 will release the extrusion force on the hose 16, and the hose 16 will be unobstructed again. When the connecting link passes by, the first spring 18 will cause the extrusion plate 14 to squeeze the hose 16 again due to the elastic potential energy, causing the hose 16 to deform and create flow obstruction, thus facilitating intermittent oil discharge.

[0026] In this embodiment, an oil limiting plate 19 is fixedly connected to the end of the bellows 3 away from the positioning plate 4. A guide post 24 is fixedly connected to the surface of the oil limiting plate 19. A fixing plate 23 is sleeved on the surface of the guide post 24. A second spring 25 is wound around the surface of the guide post 24. The two ends of the second spring 25 are respectively in contact with the oil limiting plate 19 and the fixing plate 23. Two connecting plates 22 are symmetrically fixedly connected to the surface of the fixing plate 23 by bolts. A knob 26 is threaded inside the connecting plate 22. A clamping block 21 is connected to the end of the knob 26 that rotates toward the positioning cylinder 2. A limiting groove 20 is opened in the positioning cylinder 2 at the position of the clamping block 21. The clamping block 21 is inserted into the limiting groove 20. In order to make the oil flow out of the bellows 3 with pressure, the oil limiting plate 24 is fixedly connected to the oil limiting plate 19. Plate 19 and bellows 3 are fitted together. Then, two knobs 26 are rotated. By rotating the knobs 26, the two clamps 21 are brought close to the positioning cylinder 2 and inserted into the limiting groove 20 to position the oil limiting plate 19. When the oil drain pipe 6 releases oil, the second spring 25 will cause the oil limiting plate 19 to squeeze the positioning cylinder 2 due to elastic potential energy. As the oil inside the positioning cylinder 2 gradually flows out, the positioning cylinder 2 will also contract, so that the volume of the positioning cylinder 2 changes with the volume of oil, so that the oil can be emptied as much as possible. When the positioning cylinder 2 contracts, the guide post 24 will also slide inside the fixed plate 23. The amount of oil inside the positioning cylinder 2 can be judged by observing the length of the guide post 24 remaining outside the fixed plate 23, so that oil can be added in time.

[0027] In this embodiment, an oil cleaning block 27 is fixedly connected to the support surface of the conveyor chain drive device body 1 by bolts. The oil cleaning block 27 is in close contact with the chain of the conveyor chain drive device body 1. After the chain surface is coated with oil and runs for one revolution, external dust may stick to the oil surface and accelerate the damage of the chain. Therefore, the oil cleaning block 27 can be fixed to the support surface by bolts, and the chain can be wiped by the sponge part of the oil cleaning block 27. Then, the wiped area of ​​the chain will be sprayed with oil again to achieve good lubrication. When the oil cleaning block 27 is seriously contaminated, it can be removed and replaced.

[0028] The use of this utility model involves the following steps:

[0029] S1: Before using the main body 1 of the conveyor chain drive device, first use an external oil tank to inject oil into the inside of the bellows 3 through the oil inlet pipe 5. Then, when starting the main body 1 of the conveyor chain drive device, open the valve of the oil drain pipe 6. The oil will enter the inside of the hose 16 through the first pipe 7, and then enter the inside of the second pipe 8. Then, it will be sprayed onto the chain through the atomizing nozzle 9. The atomizing nozzle 9 will atomize the oil to prevent the oil from splashing when it comes into contact with the chain due to its columnar shape. This achieves the application of lubricating oil to the chain and reduces the wear of the chain during use. In order to save oil, the hose 16 can be squeezed and deformed by pressing it, and the inner wall of the hose will shrink to stop the flow of oil. The hose 16 can be squeezed regularly and intermittently to allow the oil to be sprayed onto the chain intermittently, so as to achieve lubrication and save oil to a certain extent.

[0030] S2: To facilitate intermittent oil injection, when the chain moves, the connecting link will press the force plate 10, which will move outward and exert force on the linkage plate 11. The linkage plate 11 will rotate inside the bearing seat 12 due to the force, and at the same time, it will drive the extrusion plate 14 to move away from the hose 16 through the connecting rod 13. The first spring 18 will be compressed by the fixed plate 17, and the extrusion plate 14 will release the extrusion force on the hose 16, and the hose 16 will be unobstructed again. When the connecting link passes by, the first spring 18 will cause the extrusion plate 14 to extrude the hose 16 again due to the elastic potential energy, causing the hose 16 to deform and create flow obstruction, which facilitates intermittent oil discharge.

[0031] S3: To create pressure when oil flows out of the bellows 3, the oil limiting plate 19 is placed against the bellows 3. Then, the two knobs 26 are rotated. By rotating the knobs 26, the two clamps 21 are brought close to the positioning cylinder 2 and inserted into the limiting groove 20 to position the oil limiting plate 19. When the oil drain pipe 6 releases oil, the second spring 25 will cause the oil limiting plate 19 to squeeze the positioning cylinder 2 due to its elastic potential energy. As the oil inside the positioning cylinder 2 gradually flows out, the positioning cylinder 2 will also contract, so that the volume of the positioning cylinder 2 changes with the volume of the oil, allowing the oil to be emptied as much as possible. When the positioning cylinder 2 contracts, the guide column 24 will also slide inside the fixed plate 23. The amount of oil inside the positioning cylinder 2 can be judged by observing the length of the guide column 24 remaining outside the fixed plate 23, so that oil can be added in time.

[0032] S4: To create pressure when oil flows out of the bellows 3, the oil limiting plate 19 is placed against the bellows 3. Then, the two knobs 26 are rotated. By rotating the knobs 26, the two clamps 21 are brought close to the positioning cylinder 2 and inserted into the limiting groove 20 to position the oil limiting plate 19. When the oil drain pipe 6 releases oil, the second spring 25 will cause the oil limiting plate 19 to squeeze the positioning cylinder 2 due to its elastic potential energy. As the oil inside the positioning cylinder 2 gradually flows out, the positioning cylinder 2 will also contract, so that the volume of the positioning cylinder 2 changes with the volume of the oil, allowing the oil to be emptied as much as possible. When the positioning cylinder 2 contracts, the guide column 24 will also slide inside the fixed plate 23. The amount of oil inside the positioning cylinder 2 can be judged by observing the length of the guide column 24 remaining outside the fixed plate 23, so that oil can be added in time.
