[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0032] As Figure 1 shown, the present utility model provides an energy-saving system for a walking beam cooling bed 100, which includes an energy-saving drive assembly 1, a valve platform 2, an energy storage station 3, and a hydraulic pump station 4; the energy-saving drive assembly 1, the energy storage station 3, and the hydraulic pump station 4 are all connected to the valve platform 2. The energy-saving drive assembly 1 is connected to a lifting beam 110 on the walking beam cooling bed 100 for driving the lifting and lowering of a movable beam. A supply pipeline 5 and a recovery pipeline 6 are connected between the valve platform 2 and the energy-saving drive assembly 1. An energy storage pipeline 7 and an energy release pipeline 8 are connected between the valve platform 2 and the energy storage station 3. An oil supply pipeline 9 and an oil return pipeline 10 are connected between the hydraulic pump station 4 and the valve platform 2. The oil supply pipeline 9 is communicated with the energy storage pipeline 7 through the valve platform 2, and the energy release pipeline 8 is communicated with the supply pipeline 5 through the valve platform 2; the recovery pipeline 6 is controllably communicated with the oil return pipeline 10 and the energy storage pipeline 7 through the valve platform 2.

[0033] Specifically, as Figure 1 shown, the hydraulic pump station 4 supplies oil to the energy storage station 3 through the oil supply pipeline 9 via the valve platform 2 for energy replenishment. When the walking beam cooling bed 100 needs to be lifted, the energy storage station 3 provides stable hydraulic oil to the energy-saving drive assembly 1 through the energy release pipeline 8, the valve platform 2, and the supply pipeline 5 to drive the energy-saving drive assembly 1 to act and drive the lifting beam 110 to rise, realizing the lifting of the movable beam; when the walking beam cooling bed 100 needs to be lowered, the valve platform 2 cuts off the energy release pipeline 8 and conducts the recovery pipeline 6 and the energy storage pipeline 7. Under the action of gravitational potential energy, the energy-saving drive assembly 1 resets, so that the hydraulic oil carrying gravitational potential energy inside it flows through the recovery pipeline 6, the valve platform 2, and the energy storage pipeline 7 to the energy storage station 3 for storage, and is released and utilized by the energy storage station 3 when the walking beam cooling bed 100 needs to be lifted next time. In this way, through the recycling of gravitational potential energy, not only the energy utilization rate is improved, but also the energy consumption and operation cost are reduced, realizing energy saving and efficiency improvement.

[0034] It should be noted that, as Figure 1 shown, the energy-saving system for the walking beam cooling bed 100 is arranged at the lower part of the walking beam cooling bed 100, and the energy-saving drive assembly 1 is connected to the lifting beam 110. By sharing the original electrical drive mechanism 120 of the walking beam cooling bed 100 with the energy-saving drive assembly 1, the lifting of the movable beam can be completed through the cooperation of hydraulic lifting and electrical lifting, so as to reduce the load of the main lifting cylinder and extend its service life; and the lifting of the movable beam can also be independently completed by hydraulic lifting or electrical lifting, providing multiple guarantees for the operation of the movable beam, ensuring the safe and stable operation of the movable beam under various working conditions, and at the same time eliminating the implementation risks, making the transformation project more reliable and safe.

[0035] According to an embodiment of the present utility model, the energy-saving system for the walking beam cooling bed 100 further includes a controller, which is electrically connected to the energy-saving drive assembly 1, the valve platform 2, the energy storage station 3, and the hydraulic pump station 4. By providing the controller and electrically connecting it to the energy-saving drive assembly 1, the valve platform 2, the energy storage station 3, and the hydraulic pump station 4, the energy-saving system can be accurately controlled.

[0036] According to a preferred embodiment of the present utility model, the energy storage station 3 includes an energy storage pressure detection component for detecting its pressure, and the energy storage pressure detection component is electrically connected to the controller. When the pressure of the energy storage station 3 is lower than the preset range and the lifting beam 110 is in the ascending state, the controller controls the hydraulic pump station 4 to start to supply oil to the energy storage station 3; when the pressure of the energy storage station 3 is lower than the preset range and the lifting beam 110 is in the descending state, the controller controls the valve platform 2 to conduct the recovery pipeline 6 and the energy storage pipeline 7, and when the pressure of the energy storage station 3 reaches the preset range, the controller controls the valve platform 2 to conduct the recovery pipeline 6 and the oil return pipeline 10.

[0037] Specifically, the energy storage station 3 includes an energy storage pressure detection component for real-time monitoring of the energy storage pressure of the energy storage station 3 and feeding back a signal to the controller when the energy storage pressure is lower than the preset range, so that the controller can timely control the hydraulic pump station 4 to start to supply oil to the energy storage station 3 to ensure that the pressure of the energy storage station 3 is always maintained within the preset range, thereby ensuring sufficient power of the energy-saving drive assembly 1. Among them, the preset range of the pressure of the energy storage station 3 is determined by the kinetic energy required for the energy-saving drive assembly 1 to drive the lifting beam 110 to rise. Specifically, the kinetic energy required for the energy-saving drive assembly 1 to drive the lifting beam 110 to rise comes from the gravitational potential energy recovered during the previous descent of the walking beam cooling bed 100 and the oil supply kinetic energy of the hydraulic pump station 4. During the descent of the walking beam cooling bed 100, the controller controls the valve platform 2 to preferentially conduct the recovery pipeline 6 and the energy storage pipeline 7 so that as much gravitational potential energy of the descent of the walking beam cooling bed 100 as possible is stored in the energy storage station 3. When the pressure of the energy storage station 3 reaches the maximum value of the preset range, to avoid obstruction of the reset of the energy-saving drive assembly 1, the controller controls the valve platform 2 to cut off the energy storage pipeline 7 and conduct the recovery pipeline 6 and the oil return pipeline 10 according to the pressure signal fed back by the energy storage pressure detection component, so that the hydraulic oil inside the energy-saving drive assembly 1 directly returns to the hydraulic pump station 4 through the recovery pipeline 6, the valve platform 2, and the oil return pipeline 10. In this embodiment, the energy storage pressure detection component is preferably a pressure sensor.

[0038] According to a preferred embodiment of the present utility model, the energy storage station 3 further includes an accumulator. An accumulator pressure detection component is connected to the accumulator. An energy storage bladder is installed inside the accumulator. The energy storage bladder can convert the energy carried by the hydraulic oil into elastic potential energy and store it. Specifically, the accumulator is composed of a steel cylinder and an energy storage bladder disposed inside the steel cylinder. The energy storage bladder is made of oil-resistant rubber. Nitrogen is filled into the energy storage bladder at a specified pressure, and this pressure is precisely set according to the actual working requirements of the system. When the pressure in the system exceeds the set value, the excess energy causes the hydraulic oil to be compressed and enter the accumulator, forcing the energy storage bladder to deform. As the internal pressure increases, the volume of the energy storage bladder becomes smaller, thereby storing the energy in the gas inside the bladder. When the system needs energy, the hydraulic oil in the accumulator is quickly discharged, the volume of the energy storage bladder increases, and the stored energy is released. In this way, the accumulator realizes energy recovery and provides hydraulic oil with stable pressure and flow rate to the system.

[0039] According to a preferred embodiment of the present utility model, the valve platform 2 includes a supply control valve group and a recovery control valve group. The opening degree of the supply control valve group is adjustable. The supply control valve group is used to conduct the supply pipeline 5 and the energy release pipeline 8. The recovery control valve group is used to conduct the recovery pipeline 6 and the energy storage pipeline 7, or the recovery control valve group is used to conduct the recovery pipeline 6 and the oil return pipeline 10. Specifically, both the supply control valve group and the recovery control valve group are electrically connected to the controller. The controller controllably controls the opening degree of the supply control valve group to adjust the flow rate of the hydraulic oil, thereby realizing precise control of the rising speed and height position of the energy-saving drive assembly 1 driving the lifting beam 110. The controller controllably controls the action of the recovery control valve group to control the selective conduction of the recovery pipeline 6 and the energy storage pipeline 7 or the oil return pipeline 10, so as to balance energy recovery and the smooth reset of the energy-saving drive assembly 1.

[0040] According to a preferred embodiment of the present utility model, the supply control valve group is a proportional servo valve group to improve the control accuracy of hydraulic oil flow rate adjustment.

[0041] According to a preferred embodiment of the present utility model, the recovery control valve group is a three-way valve. Of course, the recovery control group can also be one-way switch valves respectively arranged on the energy storage pipeline 7 and the oil return pipeline 10, and the present application does not limit this.

[0042] According to a preferred embodiment of the present utility model, the energy-saving drive assembly 1 includes an energy-saving hydraulic cylinder and a crank. The working oil port of the energy-saving hydraulic cylinder is connected to the supply pipeline 5, and the oil return port of the energy-saving hydraulic cylinder is connected to the recovery pipeline 6. The crank is connected between the energy-saving hydraulic cylinder and the lifting beam 110. In the state where the lifting beam 110 descends, the crank rotates and compresses the cylinder rod of the energy-saving hydraulic cylinder, causing the hydraulic oil in the energy-saving hydraulic cylinder to flow to the valve platform 2. Specifically, when the energy-saving hydraulic cylinder is in the oil inlet state, the lever extends, drives the crank to rotate, and drives the lifting beam 110 to rise. When the lifting beam 110 reaches the rising height, the controller controls the supply control valve group on the valve platform 2 to cut off the hydraulic oil supply. Under the action of the gravitational potential energy of the lifting beam 110, the moving beam, etc., the crank rotates in the reverse direction and compresses the cylinder rod of the energy-saving hydraulic cylinder, causing the hydraulic oil in the energy-saving hydraulic cylinder to flow to the valve platform 2 through the recovery pipeline 6 until the energy-saving hydraulic cylinder is reset.

[0043] According to a preferred embodiment of the present utility model, the energy-saving drive assembly 1 further includes a position detection member for detecting the position of the energy-saving hydraulic cylinder. The position detection member is electrically connected to the controller, and the controller can control the opening degree of the supply control valve according to the position signal fed back by the position detection member. In this way, precise control of the lifting speed and lifting height of the moving beam can be achieved.

[0044] According to a preferred embodiment of the present utility model, a pipeline pressure detection member is provided on the supply pipeline 5. The pipeline pressure detection member is electrically connected to the controller, and the controller can control the original electric drive mechanism 120 of the walking beam cooler 100 to start according to the pressure signal fed back by the pipeline pressure detection member. Specifically, when the lifting beam 110 drives the moving beam to rise until the moving beam contacts the steel plate, due to the increase in load, the pipeline pressure of the supply pipeline 5 increases accordingly. The pipeline pressure detection member sends a pressure signal to the controller, and the controller receives the pressure signal and controls the original electric drive mechanism 120 of the walking beam cooler 100 to start to assist the lifting. In this embodiment, the pipeline pressure detection member is preferably a pressure sensor.

[0045] Based on the above description, the energy-saving system provided by the embodiments of the present utility model for the walking beam cooling bed 100 includes an energy-saving drive assembly 1, a valve platform 2, an energy storage station 3, and a hydraulic pump station 4; the energy-saving drive assembly 1, the energy storage station 3, and the hydraulic pump station 4 are all connected to the valve platform 2. The gravitational potential energy during the descent of the walking beam cooling bed 100 is recovered by the energy storage station 3 and released for use in the next lift of the walking beam cooling bed 100, which not only improves the energy utilization rate but also helps to reduce energy consumption and operating costs, achieving energy conservation and efficiency improvement. Among them, the energy-saving system is arranged at the lower part of the walking beam cooling bed 100, and the energy-saving drive assembly 1 is connected to the lifting beam 110. By sharing the energy-saving drive assembly 1 with the original electrical drive mechanism 120 of the walking beam cooling bed 100, the lifting of the movable beam can be completed through the cooperation of hydraulic lifting and electrical lifting, so as to reduce the load of the main lifting cylinder and extend its service life; moreover, the lifting of the movable beam can be independently completed through hydraulic lifting or electrical lifting, providing multiple guarantees for the operation of the movable beam, ensuring the safe and stable operation of the movable beam under various working conditions, and at the same time eliminating implementation risks, making the transformation project more reliable and safe; at the same time, by setting a controller and electrically connecting it to the energy-saving drive assembly 1, the valve platform 2, the energy storage station 3, and the hydraulic pump station 4, the energy-saving system can be accurately controlled.
