Description

Technical Field

[0001] The utility model relates to the technical field of walking beams, in particular to a potential energy recovery device for a walking beam. Background Art

[0002] The walking beam is one of the most commonly used steel coil transportation devices in a rolling mill. The steel coils coming out of the hot rolling coiler are generally transported by the walking beam and then transported to the finished product warehouse through a fast chain and a slow chain. The walking beam is also used to transport steel coils at the entrances and exits of cold rolling, galvanizing, and continuous annealing lines. According to the different layout positions, the walking beam is divided into an inlet walking beam and an outlet walking beam. The walking beam is generally underground, and fixed saddles with a saddle-shaped welded structure are arranged on the walking beam. Each fixed saddle is arranged at a certain distance. Each time the moving beam runs a cycle, it will move the steel coil from one fixed saddle to the next fixed saddle.

[0003] For the existing Chinese utility model patent with the reference publication number of CN220492808U, it discloses a potential energy recovery device for a lift. When the heavy object descends to the second touch limit switch (SB2), the electromagnetic clutch disconnects, and the generator is in a standby state. When the heavy object rises, it is hoisted by a winch through a pulley block. When the heavy object rises to the first touch limit switch (SB1), the electromagnetic clutch connects, and the winch is in a standby state. When the heavy object descends, its own gravity drives the drum to rotate, drives the speed increaser to increase the speed through the electromagnetic clutch, and drives the generator to generate electricity.

[0004] The existing potential energy recovery device generally drives the rotation of the generator shaft by the walking beam driving the gear to rotate to recover the potential energy of the walking beam. The walking beam and the gear are connected by a connecting rod. This method will cause the gear to rotate when the walking beam rises, and the gear will have an impact during the rising process of the walking beam. Moreover, the existing potential energy recovery device is very inconvenient to install. Summary of the Utility Model

[0026] Please refer to Figure 1 - Figure 4 , in this embodiment, a walking beam potential energy recovery device includes: a bottom plate 1, a generator 11 and a gearbox 12 are fixedly installed above the bottom plate 1, a box cover 13 is fixedly installed at the right end of the gearbox 12, an output shaft 14 is inserted and installed at the rear side of the gearbox 12, and an input shaft 15 is inserted and installed at the front end of the gearbox 12. A connecting shaft 16 is inserted through the center of the gearbox 12. Bearings 17 are fitted and installed on the surfaces of the gearbox 12 and the box cover 13. A large gear 18 and a small gear 19 are inserted through the outside of the connecting shaft 16. A flywheel 110 is inserted through the outside of the input shaft 15. A pneumatic clutch 111 is fixedly installed at the end of the input shaft 15. A steel pipe 112 is fixedly installed above the pneumatic clutch 111. An air pump 113 is fixedly installed at the left end of the steel pipe 112. A drive disk 114 is inserted through the right end of the pneumatic clutch 111. A connecting block 115 is fixedly installed on the right side of the drive disk 114. A connecting rod 116 is fixedly installed on the right side of the connecting block 115. A fixing plate 117 is inserted through the upper side of the connecting rod 116. A controller 118 is fixedly installed above the bottom plate 1.

[0027] The rotating shaft of the generator 11 is fixedly connected to the output shaft 14 in an inserted manner. The box cover 13 is fixedly connected to the gearbox 12 by screws. The output shaft 14, the input shaft 15, and the connecting shaft 16 are rotatably connected between the gearbox 12 and the box cover 13 through bearings 17. The large gear 18 is also fixedly installed on the outer side of the output shaft 14, and the small gear 19 is also fixedly installed on the outer side of the input shaft 15. The small gear 19 on the outer side of the output shaft 14 meshes with the large gear 18 on the outer side of the connecting shaft 16, and the large gear 18 on the outer side of the input shaft 15 meshes with the small gear 19 on the outer side of the connecting shaft 16. The air pump 113 is communicated with the air chamber of the pneumatic clutch 111 through a steel pipe 112. The bottom surface of the air pump 113 is fixedly connected to the bottom plate 1. The connecting block 115 is fixedly installed on the outer edge of the right side surface of the driving disc 114. A rotating connection is formed between the connecting block 115 and the connecting rod 116. A rotating connection is formed between the fixed plate 117 and the connecting rod 116. Openings for bolt installation are provided on the front and rear sides of the fixed plate 117.

[0028] Specifically, the bottom plate 1 can support the generator 11. The generator 11 can generate electricity when rotating. The gearbox 12 can protect the large gear 18 and the small gear 19 and limit the positions of the output shaft 14, the input shaft 15, and the connecting shaft 16. The output shaft 14, the input shaft 15, and the connecting shaft 16 can limit the positions of the large gear 18 and the small gear 19. The bearings 17 can facilitate the rotation of the output shaft 14, the input shaft 15, and the connecting shaft 16. The large gear 18 and the small gear 19 can increase the rotation speed of the output shaft 14. The flywheel 110 can increase the moment of inertia of the input shaft 15. The pneumatic clutch 111 can prevent the connecting shaft 16 from driving the input shaft 15 to rotate when the walking beam rises. The steel pipe 112 can facilitate the entry of gas into the air chamber of the pneumatic clutch 111. The air pump 113 can input gas into the pneumatic clutch 111 to make the sprocket of the pneumatic clutch 111 engage. The driving disc 114 can drive the pneumatic clutch 111 to rotate. The connecting block 115 can limit the positions of the lower end of the connecting rod 116 and the driving disc 114. The connecting rod 116 can facilitate the walking beam to drive the driving disc 114 to rotate. The fixed plate 117 can facilitate the connection between the connecting rod 116 and the walking beam. The controller 118 can control the start interval of the air pump 113 to match the time taken for the walking beam to move from the upper end to the lower end.

[0029] During use, the air pump 113 is connected to the air chamber of the pneumatic clutch 111 through a steel pipe 112. When the air pump 113 starts, gas enters the air chamber of the pneumatic clutch 111 through the steel pipe 112, pushing the sprocket of the pneumatic clutch 111 to engage. At this time, synchronous rotation can be achieved between the input shaft 15 and the driving disc 114. When the air pump 113 is turned off, the sprocket will separate under the drive of the return spring, and the driving disc 114 will not be able to drive the input shaft 15 to rotate. The start and stop duration of the air pump 113 is controlled by the controller 118 to match the duration of the walking beam moving from the upper end to the lower end. When the walking beam moves upward, the air pump 113 is turned off, and when the walking beam moves downward, the air pump 113 is turned on, so that the driving disc 114 is driven to rotate when the walking beam moves downward, and the upward movement of the walking beam is not affected when the walking beam moves upward. A rotational connection is formed between the fixed plate 117 and the connecting rod 116. Openings for bolt installation are provided on both the front and rear sides of the fixed plate 117. A rotational connection is formed between the connecting block 115 and the connecting rod 116. The connecting block 115 is fixed to the outer edge of the right side surface of the driving disc 114. During installation, the walking beam needs to be at the lowest position, and the connecting block 115 needs to be at the lowest point of the driving disc 114, so that the connecting rod 116 is kept vertical. Then, the fixed plate 117 is fixed to the surface of the walking beam through bolts. This method can reduce the operations during installation, facilitating the connection of the device to the walking beam.
