Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply technology for warehousing equipment, specifically a power supply and voltage regulation circuit for a four-way shuttle lifting device. Background Technology
[0002] The four-way shuttle in an automated warehouse is a high-tech warehousing and logistics handling equipment that integrates advanced functions such as automated handling, unmanned guidance, and intelligent control, providing an efficient, flexible, and intelligent solution for modern warehousing and logistics systems.
[0003] The lifting device of the four-way shuttle includes a chassis control platform and a connecting platform, which are set up vertically. The chassis control platform and the connecting platform are electrically connected by four steel belts. Two steel belts are used to transmit communication signals, and the other two steel belts are used to provide 24V power supply. The control board on the connecting platform is electrically connected to the steel belts to achieve power supply or communication. The four-way shuttle uses vertical up and down transportation technology. When moving up and down, the steel belts will also roll. However, due to the high impedance of the steel belts themselves, the effective length and cross-sectional area of the power supply lines formed by the steel belts (the sides of the steel belts are in direct contact when they are rolled) will change when the steel belts are rolled up and down, which will cause the power supply voltage to be unstable. In addition, there is swaying during the rolling of the steel belts, which can easily cause changes in the contact impedance between the brushes and the steel belts, which will lead to unstable power supply to the control board on the connecting platform and cause abnormal control operation. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a power supply and voltage regulation circuit for a four-way shuttle lifting device, which can stabilize the operating voltage and ensure normal control operation.
[0005] This utility model adopts the following technical solution: a power supply and voltage regulation circuit for a four-way shuttle lifting device, including a control board installed on a connecting platform. A chassis central control platform is provided above the connecting platform. The connecting platform and the chassis central control platform are electrically connected by a steel strip. One end of the steel strip is connected to a brush, and the other end of the steel strip is connected to the control board. The control board is equipped with an input interface J1, an output interface J2, a switching power supply U1, a diode D1, and an energy storage device. The other end of the steel strip is connected to the input interface J1. The positive terminal of the diode D1 is connected to pin 1 of the input interface J1. The negative terminal of the diode D1 is connected to the switching power supply U1 after being connected to the energy storage device.

[0006] Furthermore, the switching power supply U1 is a model SCW12B-05 switching power supply, the energy storage device is a capacitor C1, and the control board is also equipped with a diode D2 and a resistor R1. The cathode of the diode D1 is connected to one end of the resistor R1 and the cathode of the diode D2, and then connected to pins 22 and 23 of the switching power supply U1. The other end of the resistor R1 is connected to the anode of the diode D2 and one end of the capacitor C1. Pin 2 of the input interface J1 is connected to the other end of the capacitor C1 and pins 2 and 3 of the switching power supply U1, and then grounded. Pin 14 of the switching power supply U1 is connected to pin 1 of the output interface J2, and pin 16 of the switching power supply U1 is connected to pin 2 of the output interface J2.
[0007] Furthermore, the input interface J1 achieves 24V input after being connected to the steel strip, and the output interface J2 achieves 5V output after being connected to the switching power supply U1;
[0008] Furthermore, the chassis central control platform includes a frame, a connecting rod is mounted on the frame, a connecting shaft is mounted between the connecting rod and one side of the frame, and corresponding reels are mounted on both ends of the connecting shaft and the corresponding connecting platform. The steel strip is wound around the corresponding reel, and the brush is mounted on the frame at the position of the reel. The brush and the reel overlap each other.
[0009] Furthermore, the portion of the connecting shaft that contacts the reel is made of an insulating material, while the reel is made of a conductive material.
[0010] Furthermore, the steel strip is divided into a first steel strip, a second steel strip, a third steel strip, and a fourth steel strip. The first steel strip, the second steel strip, the third steel strip, and the fourth steel strip are respectively wound on the corresponding reels. The first steel strip and the second steel strip are used to provide 24V power supply, and the third steel strip and the fourth steel strip are used to transmit communication signals. The first steel strip and the second steel strip are connected to the input interface J1.
[0011] The beneficial effect of this utility model is that it is equipped with an energy storage device on the control board to store electrical energy. When the voltage is unstable during the steel strip winding process, the energy storage device can release electrical energy to stabilize the voltage, thereby ensuring normal control operation and having good economic value.

[0013] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0014] like Figure 1, Figure 2 As shown, the present invention discloses a power supply and voltage regulation circuit for a four-way shuttle lifting device, comprising a control board 2 installed on a connecting platform 1, a chassis central control platform 3 disposed above the connecting platform 1, and the connecting platform 1 and the chassis central control platform 3 electrically connected by a steel strip. One end of the steel strip is connected to a brush 4, and the other end of the steel strip is connected to the control board 2. The control board 2 is provided with an input interface J1, an output interface J2, a switching power supply U1, a diode D1, and an energy storage device. The other end of the steel strip is connected to the input interface J1. The positive terminal of the diode D1 is connected to pin 1 of the input interface J1, and the negative terminal of the diode D1 is connected to the switching power supply U1 after being connected to the energy storage device. The output terminal of the switching power supply is connected to the output interface J2.
[0015] The switching power supply U1 uses model SCW12B-05, and the energy storage component is capacitor C1. Control board 2 also has diode D2 and resistor R1. The cathode of diode D1 is connected to one end of resistor R1, and the cathode of diode D2 are also connected to pins 22 and 23 of switching power supply U1. The other end of resistor R1 is connected to the anode of diode D2 and one end of capacitor C1. Pin 2 of input interface J1 is connected to the other end of capacitor C1 and pins 2 and 3 of switching power supply U1, and then grounded. Pin 14 of switching power supply U1 is connected to pin 1 of output interface J2, and pin 16 of switching power supply U1 is connected to pin 2 of output interface J2. Input interface J1 achieves 24V input after being connected to the steel strip, and output interface J2 achieves 5V output after being connected to switching power supply U1.
[0016] Among them, resistor R1 acts as a current-limiting resistor to control the current when capacitor C1 is charged, preventing the charging current from being too large and impacting the input power supply terminal, thereby avoiding the situation where the input power supply is overloaded due to instantaneous large current, and thus protecting the power supply.
[0017] Diode D1 acts as a reverse connection protection diode. When the input power supply voltage V1 is high, it can charge capacitor C1 and supply power to switching power supply U1, ensuring that the limited energy stored is supplied only to control board 2 and not back to the power input terminal. When the input power supply voltage V1 is too low, it prevents the energy in capacitor C1 from being back supplied to the power input terminal, and the limited energy is only supplied to one end of control board 2.
[0018] Diode D2 acts as a discharge diode. When the input voltage V1 decreases, capacitor C1 discharges through diode D2.
[0019] The switching power supply U1 is a wide-voltage DC-DC regulator chip that can convert 18-36V fluctuating input into a stable 5V output to the output interface J2.
[0020] The chassis central control platform 3 includes a frame 5, on which a connecting rod 6 is mounted. A connecting shaft 7 is mounted between the connecting rod 6 and one side of the frame 5. Corresponding reels 8 are mounted on both ends of the connecting shaft 7 and on the corresponding connecting platform 1. Steel strips are wound around the corresponding reels 8. Brushes 4 are mounted on the frame 5 at the positions corresponding to the reels 8, and the brushes 4 overlap with the reels 8. The contact parts between the connecting shaft 7 and the reels 8 are made of insulating material to achieve electrical isolation, while the reels 8 are made of conductive material. The steel strips are divided into a first steel strip 9, a second steel strip 10, a third steel strip 11, and a fourth steel strip 12. The steel strips 12 are wound onto the corresponding reels 8. The first steel strip 9 and the second steel strip 10 are used to provide 24V power supply, and the third steel strip 11 and the fourth steel strip 12 are used to transmit communication signals. The first steel strip 9 and the second steel strip 10 are connected to the input interface J1. In fact, the brush 4 conducts electricity after it overlaps with the reel 8 on which the steel strip is wound, and transmits power to the first steel strip 9 and the second steel strip 10. The lower ends of the first steel strip 9 and the second steel strip 10 are connected to the input interface J1 through wires. The two adjacent reels 8 are insulated from each other. The third steel strip 11 and the fourth steel strip 12 are connected to the corresponding signal transmission interface (not shown in the figure) on the control board 2.
[0021] In this invention, a capacitor C1 is installed on the control board 2. Normally, it stores electrical energy. When the voltage drops, capacitor C1 automatically releases energy to stabilize the voltage. Specifically, when the input voltage V1 is stable, V1 is greater than V2, diode D1 conducts, charging capacitor C1 through current-limiting resistor R1 and simultaneously supplying power to switching power supply U1, thus converting it into voltage V3, which is output through output interface J2. When the input voltage V1 is unstable, V2 is greater than V1, diode D1 is cut off, and capacitor C1 supplies power to switching power supply U1 through discharge diode D2, thereby ensuring the stability of voltage V3. Since diode D1 is cut off, all the energy of capacitor C1 is provided to control board 2.
