The thick plate cooling bed is a hydraulic walking cooling bed. Among them, the hydraulic walking cooling bed generally controls the height through a lifting device. When the lifting device of the hydraulic walking cooling bed descends, the hydraulic oil in the lifting device is discharged. The hydraulic energy and gravitational potential energy in these hydraulic oils are not effectively utilized, but are converted into heat energy and released. This waste of energy not only affects the efficiency of the system, but may also cause the temperature of the hydraulic oil to rise, thereby affecting the stability and service life of the system. Therefore, how to realize the conversion and utilization of hydraulic energy during the use of the cooling bed has become a technical problem that needs to be solved urgently. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please refer to Figure 1 As shown, a hydraulic walking cooling bed energy storage system is provided in an embodiment of the present invention, which includes a walking cooling bed 100, a lifting mechanism 200 and a potential energy recovery mechanism 300. The walking cooling bed 100 includes a fixed frame 110 for supporting a thick plate, and the fixed frame 110 is arranged to be liftable; the lifting mechanism 200 includes a lifting hydraulic cylinder 210 and a first transmission structure 220 connecting the lifting hydraulic cylinder 210 and the fixed frame 110, the lifting hydraulic cylinder 210 is connected to the driving oil circuit 310, and the lifting hydraulic cylinder 210 is used to adjust the setting height of the fixed frame 110; the potential energy recovery mechanism 300 includes an oil circuit control mechanism 320 arranged on the driving oil circuit 310, and an energy storage device 330 connected to the oil circuit control mechanism 320, and the oil circuit control mechanism 320 is controllably connected to the lifting hydraulic cylinder 210 and the energy storage device 330.

[0033] On the whole, when the hydraulic walking cooling bed energy storage system of the present invention is used, the walking cooling bed 100 can support the hot-rolled thick plate through the fixed frame 110, and by connecting the lifting mechanism 200 to the fixed frame 110, the setting height of the fixed frame 110 can be adjusted by using the lifting mechanism 200, which facilitates the subsequent use with the movable frame 120 to transport the hot-rolled thick plate, thereby achieving a better transportation effect.

[0034] When the height of the fixing frame 110 is lowered, the hydraulic oil in the lifting hydraulic cylinder 210 flows out. At this time, the lifting hydraulic cylinder 210 and the energy storage device 330 are connected through the oil circuit control mechanism 320, so that the hydraulic oil in the lifting hydraulic cylinder 210 flows into the energy storage device 330, thereby recovering the hydraulic energy and gravitational potential energy in the hydraulic oil.

[0035] When the height of the fixing frame 110 rises, the oil circuit control mechanism 320 is used to connect the lifting hydraulic cylinder 210 and the energy storage device 330, so that the hydraulic oil in the energy storage device 330 flows into the lifting hydraulic cylinder 210 to provide lifting power; when the hydraulic oil power in the energy storage device 330 is insufficient, the lifting hydraulic cylinder 210 can also be connected to the cooling bed hydraulic station 500 through the oil circuit control mechanism 320, so that the cooling bed hydraulic station 500 can be used to provide subsequent power.

[0036] During the descending process of the fixed frame 110 of the walking cooling bed 100, the utility model can absorb and store most of the hydraulic energy and gravitational potential energy of the hydraulic oil. The stored hydraulic oil energy can also be released when the fixed frame 110 rises, thereby realizing the recycling of the hydraulic energy and gravitational potential energy of the hydraulic oil, improving the utilization rate of energy, and helping to reduce energy consumption and operating costs.

[0037] In an embodiment of the present utility model, the walking cooling bed 100 also includes a movable frame 120 for conveying thick plates, and the hydraulic walking cooling bed energy storage system also includes a transverse movement mechanism 400. The transverse movement mechanism 400 includes a transverse movement hydraulic cylinder 410 and a second transmission structure 420 connecting the transverse movement hydraulic cylinder 410 and the movable frame 120. The transverse movement hydraulic cylinder 410 is connected to the driving oil circuit 310, and the transverse movement hydraulic cylinder 410 is used to drive the movable frame 120 to move back and forth.

[0038] By providing the movable frame 120, the movable frame 120 can reciprocate, and the movable frame 120 cooperates with the fixed frame 110 to transport hot-rolled thick plates, achieving better transportation efficiency. Designers can adjust the specific structure of the fixed frame 110 and the movable frame 120 according to usage needs. For example, the fixed frame 110 can be formed by fixed beams, and the movable frame 120 can be formed by movable beams. No specific limitation is given here.

[0039] Specifically, the second transmission structure 420 includes a transmission connecting rod disposed between the traverse hydraulic cylinder 410 and the movable frame 120. During operation, the traverse hydraulic cylinder 410 drives the transmission connecting rod, which in turn propels the movable frame 120 back and forth, thereby achieving traverse motion. Multiple traverse hydraulic cylinders 410 may be provided, with the multiple traverse hydraulic cylinders 410 working together to propel the movable frame 120 back and forth. Designers can adjust the number and location of the traverse hydraulic cylinders 410 based on specific needs and are not specifically limited here.

[0040] Furthermore, the transverse hydraulic cylinder 410 is connected to the driving oil circuit 310, so that the oil circuit control mechanism 320 can controllably connect the transverse hydraulic cylinder 410 and the energy storage device 330, so that the hydraulic oil recovered in the energy storage device 330 can also flow into the transverse hydraulic cylinder 410 to provide power for reciprocating motion, thereby saving energy consumption.

[0041] The transverse movement mechanism 400 can be operated independently or synchronously by electrical means. The designer can adjust the specific structure of the transmission connecting rod according to the use requirements, and no specific limitation is imposed here.

[0042] In an embodiment of the present invention, multiple groups of walking cooling beds 100 are provided, and the walking cooling beds 100 are arranged side by side along the thick plate conveying path.

[0043] By providing multiple groups of walking cooling beds 100 and arranging the multiple groups of walking cooling beds 100 side by side, the multiple groups of walking cooling beds 100 can be used to collaboratively transport thick plates after hot rolling.

[0044] Each group of walking cooling beds 100 can be raised independently, so that each walking cooling bed 100 can be flexibly adjusted according to different production requirements. For example, when cleaning or maintenance is required, a certain group of walking cooling beds 100 can be raised independently without affecting the normal operation of other groups of walking cooling beds 100.

[0045] Among them, each walking cooling bed 100 is provided with a lifting mechanism 200, and the oil circuit control mechanism 320 is respectively connected to the lifting hydraulic cylinder 210 of each lifting mechanism 200, so that the oil circuit control mechanism 320, each lifting hydraulic cylinder 210 and the energy storage device 330 are networked and used together.

[0046] When part of the walking cooling bed 100 is in the process of descending, the energy storage device 330 can be used to recover the gravitational potential energy of the hydraulic oil in each lifting hydraulic cylinder 210 in the process of descending.

[0047] When part of the walking cooling bed 100 is in the lifting process, the energy storage device 330 can be used to supply the recovered hydraulic oil to each lifting hydraulic cylinder 210 in the lifting process, thereby reducing the energy consumption of each lifting hydraulic cylinder 210 in the lifting process and saving energy. In addition, by networking the lifting hydraulic cylinders 210, a better potential energy recovery effect is achieved.

[0048] At the same time, through electrical synchronous control, each group of stepping cooling beds 100 can also be lifted synchronously to ensure the stability and balance of the entire cooling bed system during the lifting process.

[0049] Preferably, there are two groups of walking cooling beds 100. The two groups of walking cooling beds 100 constitute the front and rear parts of the cooling bed system respectively, and the two groups of walking cooling beds 100 can cooperate with each other to transport the hot-rolled plates.

[0050] Of course, in other feasible embodiments, designers can adjust the specific number and arrangement of the walking cooling bed 100 according to usage needs, and no specific limitation is made here.

[0051] In an embodiment of the present invention, the lifting mechanism 200 includes a plurality of lifting hydraulic cylinders 210, which are arranged in parallel. The oil circuit control mechanism 320 controllably connects each lifting hydraulic cylinder 210 with the energy storage device 330. Specifically, the lifting hydraulic cylinders 210 can be installed on a ground foundation to more stably support the fixing frame 110.

[0052] By providing multiple lifting hydraulic cylinders 210, the multiple lifting hydraulic cylinders 210 cooperate to improve the lifting and lowering stability of the fixing frame 110, thereby achieving better performance. The designer can adjust the specific number and arrangement of the lifting hydraulic cylinders 210 according to the actual needs, and no specific restrictions are imposed here.

[0053] In an embodiment of the present invention, the first transmission structure 220 includes a transmission crank disposed between the lifting hydraulic cylinder 210 and the fixing frame 110. The lifting hydraulic cylinder 210 fixed to the ground foundation can drive the transmission crank to move, and the transmission crank can then push the fixing frame 110 up or down.

[0054] Furthermore, the lifting hydraulic cylinder 210 is connected to the transmission crank by a front and rear earring hinge. When the lifting hydraulic cylinder 210 is extended, it drives the transmission crank to rotate, causing the transmission crank to swing, thereby pulling the fixed frame 110 to lift. Among them, the lifting mechanism 200 can operate independently or synchronously through the electrical control of the hydraulic cylinder.

[0055] In an embodiment of the present invention, the oil circuit control mechanism 320 includes a servo control valve assembly disposed on the drive oil circuit 310. The servo control valve assembly controllably connects the lifting hydraulic cylinder 210, the energy storage device 330, and the cooling bed hydraulic station 500, thereby enabling controllable energy storage. Designers can adjust the specific structure of the servo control valve assembly based on specific needs. For example, the servo control valve assembly may include a servo control valve, and this is not specifically limited here.

[0056] In an embodiment of the present invention, the energy storage device 330 is a hydraulic accumulator, which can store hydraulic oil and recover the gravitational potential energy in the hydraulic oil.

[0057] By recycling the gravitational potential energy in the hydraulic oil, the load on the lifting hydraulic cylinder 210 is significantly reduced. During the lifting process of the fixed frame 110, the hydraulic accumulator cooperates with it to complete the lifting action.

[0058] This not only enhances the stability of the lifting process but also significantly absorbs the impact of load fluctuations during the movement of the fixed frame 110, thereby improving its stress state, thereby increasing the operational stability of the fixed frame 110 and helping to extend its service life. Furthermore, potential energy that would otherwise be lost as heat is effectively recovered and reused. As a result, the system's demand for cooling water is significantly reduced. This not only reduces cooling water consumption but also helps lower the maintenance costs of the cooling system.

[0059] Designers can adjust the specific structure of the hydraulic accumulator according to usage requirements, such as the hydraulic accumulator tank, etc., and no specific restrictions are imposed here.
