[0002] When the lifting device of the walking cooling bed rises, it needs to overcome not only the weight of the equipment itself, but also the weight of the steel plate. This means that a lot of energy is required to ensure that the lifting device can rise stably and smoothly.

[0003] When the lifting device of the stepping cooling bed descends, the kinetic energy originally used for lifting will be converted into potential energy and returned to the power system. However, in this process, most of the original potential energy is not effectively utilized, but converted into heat energy and released in other ways. This waste of energy not only affects the efficiency of the system, but may also cause the temperature of the equipment to rise, affecting the stability and service life of the system.

[0034] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] like Figure 1 and Figure 2As shown, the present invention provides an energy-saving walking cooling bed, comprising a cooling bed body 1, a transmission device 2, an energy recovery device 3 and an energy storage device 4. The cooling bed body 1 is connected to the transmission device 2, and the transmission device 2 is used to drive the movable beam 11 of the cooling bed body 1 to perform lifting and lowering movements; the energy recovery device 3 is connected between the transmission device 2 and the energy storage device 4, and a recovery channel 5 and a supply channel 6 are connected between the energy recovery device 3 and the transmission device 2, and an energy storage channel 7 and an energy release channel 8 are connected between the energy recovery device 3 and the energy storage device 4. When the movable beam 11 is descending, energy is transferred from the transmission device 2 to the energy storage device 4 through the recovery channel 5, the energy recovery device 3, and the energy storage channel 7 in sequence; when the movable beam 11 is rising, energy is transferred from the energy storage device 4 to the transmission device 2 through the energy release channel 8, the energy recovery device 3, and the supply channel 6 in sequence. In this way, the gravity potential energy of the cooling bed is obtained by the energy recovery device 3 and stored in the energy storage device 4 to supply the next lifting of the movable beam 11, thereby improving the utilization rate of the gravity potential energy of the cooling bed and achieving the purpose of energy saving and emission reduction.

[0036] According to one embodiment of the present invention, the transmission device 2 is a hydraulic transmission device or an electric transmission device. Specifically, when the transmission device 2 is a hydraulic transmission device, the transmission device 2 is driven by hydraulic energy, and the energy recovery device 3 converts the gravitational potential energy at the high position of the cooling bed into hydraulic energy and stores it in the energy storage device 4. In this case, the energy recovery device 3 is preferably a hydraulic valve group, and the energy storage device 4 is preferably an accumulator. When the transmission device 2 is an electric transmission device, the transmission device 2 is driven by electric energy, and the energy recovery device 3 converts the gravitational potential energy at the high position of the cooling bed into electric energy and stores it in the energy storage device 4. In this case, the energy recovery device 3 is preferably a generator, and the energy storage device 4 is preferably an energy storage battery.

[0037] According to a preferred embodiment of the present invention, Figure 1As shown, the transmission device 2 is a hydraulic transmission device, including a hydraulic cylinder and a hydraulic rocker arm. The working oil port of the hydraulic cylinder is connected to the supply channel 6, the return oil port of the hydraulic cylinder is connected to the recovery channel 5, and the hydraulic rocker arm is connected between the hydraulic cylinder and the lifting beam 12 used to drive the movable beam 11 to rise and fall. When the movable beam 11 is lowered, the hydraulic rocker arm rotates and compresses the cylinder rod of the hydraulic cylinder, so that the hydraulic oil in the hydraulic cylinder flows to the energy recovery device 3. Specifically, the hydraulic transmission device includes a hydraulic cylinder and a hydraulic rocker arm connected to each other. In the oil supply state, the hydraulic oil enters the hydraulic cylinder from the energy storage device 4 through the energy release channel 8, the energy recovery device 3, and the supply channel 6, pushing the cylinder rod of the hydraulic cylinder to extend and driving the hydraulic rocker arm to rotate, so that the lifting beam 12 drives the movable beam 11 to rise; after the oil supply is stopped, under the action of the gravitational potential energy of the high position of the cooling bed, the hydraulic rocker arm rotates in the opposite direction and compresses the cylinder rod of the hydraulic cylinder, so that the hydraulic oil in the hydraulic cylinder is in a high-pressure state. The hydraulic oil carries the energy released when the cooling bed descends and flows to the energy storage device 4 at high speed through the recovery channel 5, the energy recovery device 3, and the energy storage channel 7, thereby realizing the recovery and storage of the gravitational potential energy of the high position of the cooling bed.

[0038] According to one embodiment of the present invention, the energy recovery device 3 includes a first valve group and a second valve group, the first valve group is connected between the recovery channel 5 and the energy storage channel 7, the second valve group is connected between the energy release channel 8 and the supply channel 6, the first valve group is used to make the hydraulic oil flow into the energy storage device 4 at a stable flow rate, and the second valve group is used to make the hydraulic oil flow into the transmission device 2 at a stable pressure. In this way, the stable rise of the movable beam 11 and the safe storage of the recovered gravitational potential energy are achieved.

[0039] According to one embodiment of the present invention, the energy storage device 4 includes an accumulator, and 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 equipped with a highly elastic and pressure-resistant energy storage bladder. When the hydraulic oil in a high-pressure state enters the accumulator, the energy storage bladder expands rapidly, converting the hydraulic energy into elastic potential energy and storing it. Among them, a control valve is provided on the accumulator. By opening the control valve, the hydraulic energy stored in the accumulator can be released back to the hydraulic system to achieve the reuse of recovered energy.

[0040] According to a preferred embodiment of the present invention, Figure 2 As shown, the transmission device 2 is an electric transmission device, including a motor, a reducer, and a crank swing rod, the reducer is connected between the motor and the crank swing rod, and the crank swing rod is connected with a lifting beam 12 for driving the movable beam 11 to rise and fall. Specifically, the electric transmission device includes a motor, a reducer, and a crank swing rod, the motor is connected to the crank swing rod through the reducer, and the crank swing rod is connected to the lifting beam 12. When the motor is driven, the reducer rotates and drives the crank swing rod to rotate, so that the lifting beam 12 drives the movable beam 11 to rise.

[0041] According to one embodiment of the present invention, the energy recovery device 3 includes a generator, which is connected to a speed reducer. When the movable beam 11 is lowered, the crankshaft rotates and drives the speed reducer to accelerate in the reverse direction, so that the generator rotates and provides electrical energy to the energy storage device 4. Specifically, after the motor stops driving, under the action of the gravitational potential energy of the high position of the cooling bed, the crankshaft rotates in the reverse direction at a small angle to drive the speed reducer to accelerate in the reverse direction, and then drives the generator connected thereto to rotate, providing electrical energy to the energy storage device 4. In this embodiment, the recovery channel 5 is composed of a speed reducer, the energy storage channel 7 is composed of a connecting cable between the generator and the energy storage device 4, and the energy release channel 8 and the supply channel 6 are composed of a connecting cable between the energy storage device 4 and the motor, that is, in this embodiment, the energy supply path may not pass through the energy recovery device 3, and the energy release channel 8 and the supply channel 6 are combined into one.

[0042] According to one embodiment of the present invention, the energy storage device 4 includes an energy storage battery. When the movable beam 11 is in a descending state, the energy storage battery is in a charging state, and when the movable beam 11 is in an ascending state, the energy storage battery is in a power supply state. Specifically, when the cooling bed is descending, the gravitational potential energy at the high position of the cooling bed is converted into electrical energy by driving the generator, so that the energy storage battery is in a charging state, and the electrical energy entering the energy storage battery is finally stored in the energy storage battery in the form of chemical energy; when the cooling bed is ascending, the energy storage battery is in a power supply state, and the chemical energy stored therein is released in the form of electrical energy, and supplied to the motor via the connecting cable.

[0043] According to a preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the energy-saving walking cooling bed also includes an energy distribution device 9, which is connected between the energy storage device 4 and other power transmission mechanisms of the cooling bed body 1. When the energy stored in the energy storage device 4 is greater than the energy required for the movable beam 11 to rise to the target position next time, the energy distribution device 9 can distribute the excess energy stored in the energy storage device 4 to other transmission components of the cooling bed body 1. Specifically, since the speed, force and stroke of each lifting of the movable beam 11 are not constant, the gravitational potential energy obtained in the last lifting may be greater than the kinetic energy required for the next lifting. By setting the energy distribution device 9, the excess energy stored in the energy storage device 4 can be reasonably allocated to other transmission components, further improving the utilization rate of the recovered energy.

[0044] According to one embodiment of the present invention, the energy-saving walking cooling bed also includes an energy replenishment device, which is connected to the energy storage device 4 through the energy distribution device 9, and the energy replenishment device is used to replenish the energy of the energy storage device 4. In this embodiment, the energy distribution device 9 is electrically connected to the control system of the walking cooling bed, and the control system obtains the relevant information of this lifting and the relevant information of the next lifting, and calculates the gravitational potential energy that can be obtained in this lifting and the kinetic energy required for the next lifting, and sends it to the energy distribution device 9, and the energy distribution device 9 integrates the received information into a corresponding distribution control program to achieve the reasonable allocation of the energy stored in the energy storage device 4. When the gravitational potential energy obtained in this lifting is less than the kinetic energy required for the next lifting, the energy distribution device 9 integrates the information into an energy replenishment control program and transmits it to the energy replenishment device, so that the energy replenishment device automatically starts to replenish energy to the energy storage device 4 to ensure the smooth progress of the next lifting. By electrically connecting the energy distribution device 9 to the control system of the walking cooling bed to realize the acquisition of the basic information of the distribution, the cost increase caused by the separate setting of the control module of the distribution device to obtain the above information is avoided. In this embodiment, when the transmission device 2 is preferably a hydraulic transmission device, the energy replenishment device is preferably an auxiliary hydraulic pump station; when the transmission device 2 is preferably an electric transmission device, the energy replenishment device is preferably an auxiliary charging station.

[0045] like Figure 3 As shown, the present invention also provides a method for distributing energy recovered by an energy-saving walking cooling bed, which is applicable to the above-mentioned energy-saving walking cooling bed, and the method for distributing energy recovered by the energy-saving walking cooling bed includes: obtaining information of this lifting, which includes the weight of the steel plate lifted this time, the weight of each component lifted this time, and the total weight lifted this time; determining the potential energy that can be obtained by this lifting based on the information obtained for this lifting; obtaining information for the next lifting, which includes the weight of the steel plate lifted next time, the distance lifted next time, and the weight of the component lifted next time; determining the kinetic energy required for the next lifting based on the information obtained for the next lifting; the energy distribution device 9 determines the distribution of energy stored in the energy storage device 4 according to the potential energy that can be obtained by this lifting and the kinetic energy required for the next lifting.

[0046] Specifically, the control system of the walking cooling bed monitors the speed of each movement of the cooling bed and the current load in real time. This information is the basis of the dynamic adjustment strategy and is directly related to whether the walking cooling bed can process the steel plates smoothly and efficiently. The control system of the walking cooling bed is responsible for collecting and processing production information, including key data such as the weight, quantity, and specifications of the steel plates. This information is combined with the remaining energy reserves (such as residual potential energy, kinetic energy reserves, etc.) of the cooling bed after this operation to provide data support for subsequent operations; and the latest steel plate weight parameters are obtained through the specific interface of the walking cooling bed. This parameter directly affects the accuracy and efficiency of the cooling bed in processing the steel plates. After obtaining the weight of the steel plates, the control system will immediately integrate the total weight of the steel plates that the current walking cooling bed plans to lift, and calculate the gravitational potential energy that can be obtained by lifting these steel plates to the target high position of the cooling bed, and send it to the energy distribution device 9. At the same time, the control system will determine the actual weight of each component (such as transmission mechanism, support structure, etc.) of the walking cooling bed during this lifting process to ensure that all relevant factors can be fully considered when calculating the kinetic energy required for the next lifting to avoid omissions or misjudgments; based on the above information, the control system will further calculate the kinetic energy required for the walking cooling bed in the next lifting and send it to the energy distribution device 9. The energy distribution device 9 integrates and optimizes the received potential energy information available for this lifting and the kinetic energy information required for the next lifting, and determines the corresponding distribution control program.

[0047] Among them, the steel plate on the stepping cooling bed is lifted to a certain height by the action of the hydraulic cylinder or other lifting mechanism. The potential energy accumulated in this process is the gravitational potential energy of the target high position of the cooling bed. The gravitational potential energy is determined by the mass of the steel plate, the mass of the lifting component, the target height to be lifted, and the gravitational acceleration. It can be calculated by the formula E=mgh, where m is the total mass and g is the gravitational acceleration (about 9.8m / s 2 ), h is the target height of lifting, and the calculation result reflects the maximum energy that the cooling bed system can release in the current state, that is, the maximum potential energy that can be obtained in this lifting. For the next lifting, the control system needs to pre-evaluate the required energy, usually based on the specific requirements of the operation, such as the weight of the steel plate, the lifting height, the resistance to be overcome (such as the gravity of the lifting parts), etc., and also considers factors such as efficiency loss and safety margin to ensure the accuracy of the energy demand prediction for the next lifting.

[0048] According to a preferred embodiment of the present invention, the distribution of energy stored in the energy storage device 4 is determined according to the potential energy obtained by this lifting and the kinetic energy required for the next lifting, including: when the potential energy obtained by this lifting is greater than the kinetic energy required for the next lifting, the energy distribution device 9 distributes the excess energy stored in the energy storage device 4 to other transmission components as needed; when the potential energy obtained by this lifting is less than the kinetic energy required for the next lifting, the energy distribution device 9 preferentially distributes the energy stored in the energy storage device 4 to the transmission device 2, and the energy distribution device 9 enables the energy replenishment device to replenish energy to the energy storage device 4. Specifically, the control system of the stepping cooling bed will also transmit the kinetic energy information required by other transmission components of the cooling bed to the energy distribution device 9. When the gravitational potential energy of the target high position of the cooling bed is greater than or equal to the energy required for the next lifting, it indicates that the energy stored in the energy storage device 4 after this lifting is sufficient to support the next lifting, and no additional energy replenishment is required, and the energy distribution device 9 will distribute the excess energy in the energy storage device 4 to other transmission components as needed. At this time, the energy replenishment device will remain closed or in standby state, which not only saves energy, but also reduces mechanical wear and maintenance costs. When the gravitational potential energy of the target high position of the cooling bed is less than the energy required for the next operation, it indicates that additional energy is needed to support the next lifting. In this case, the energy distribution device 9 will integrate the information into an energy replenishment control program, and transmit it to the energy replenishment device after the current lifting is reset, so that the energy replenishment device automatically starts to replenish the energy storage device 4 to replenish the missing energy and ensure that the next lifting can proceed smoothly. In this way, the calculation information transmitted by the control system of the stepping cooling bed is used as the basis for allocation, and the energy is allocated on demand to ensure efficient use of energy and stable operation of the system.

[0049] Based on the above description, the energy-saving walking cooling bed provided in the embodiment of the present application obtains the gravitational potential energy of the target high position of the cooling bed through the energy recovery device 3 and stores it in the energy storage device 4 to supply the next lifting of the movable beam 11. By recycling the potential energy that would otherwise be converted into heat energy loss, the system's demand for cooling is reduced, and the utilization rate of the gravitational potential energy of the cooling bed is improved, thereby achieving the purpose of energy saving and emission reduction. At the same time, the stability of the lifting process of the movable beam 11 is enhanced, and the impact of the movable beam 11 caused by load fluctuations during movement is significantly absorbed, thereby improving the stress state of the movable beam 11 and helping to extend its service life; by setting an energy distribution device 9, when the gravitational potential energy obtained in the last lifting is greater than the kinetic energy required for the next lifting, the excess energy stored in the energy storage device 4 is reasonably allocated to other transmission components, further improving the utilization rate of the recovered energy; and in conjunction with the energy replenishment device, when the gravitational potential energy obtained in the last lifting is less than the kinetic energy required for the next lifting, the energy distribution device 9 is used to automatically replenish the energy to the energy storage device 4 to ensure the smooth progress of the next lifting. The energy recovery distribution method of the energy-saving walking cooling bed provided in the embodiment of the present application is based on the potential energy that can be obtained from this lifting and the kinetic energy required for the next lifting, taking into account both the efficient use of energy and the stable operation of the system.

[0050] The above are only several embodiments of the present invention.
