Description

Technical Field

[0001] This utility model relates to the field of electrical equipment bearing technology, and in particular to an adaptive regulating power supply device. Background Technology

[0002] A search of existing technology with patent number CN223052912U reveals an adaptive regulating power supply device for low-voltage engineering, which achieves the lifting of a fixed platform through a base, transmission frame, and lifting components (including a moving seat, transmission rack, rotating gear, etc.). While the aforementioned power supply equipment solves the problem of asynchronous lifting and lowering of the four corners of the fixed platform caused by the traditional four-corner extension columns and hydraulic devices, it has significant drawbacks: First, the asymmetrical power output structure, which uses two telescopic rods on one side for guidance and stability while the lifting assembly on the other side provides power, easily leads to force imbalance on the fixed base during lifting and lowering, affecting operational stability. Second, the lifting assembly relies on the angle adjustment of the driven boom and the driving boom to provide power. When the weight of the power module changes, the force state of the driven boom and the driving boom will change accordingly. If the load exceeds the design threshold, it can easily cause safety hazards such as bending or breakage of the two booms. Therefore, an adaptive adjustment power supply equipment is proposed to solve the above problems. Utility Model Content

Four telescopic rods can provide guidance and stability for the fixed seat during lifting and lowering, while the lifting drive mechanism installed in the middle between the fixed seat and the base plate can provide a lifting and lowering power for the fixed seat, thereby preventing uneven force distribution during the lifting and lowering of the fixed seat and improving the stability of operation.

[0004] (II) Technical Solution This utility model provides an adaptive power supply device, including a horizontally arranged base plate and a fixed seat located directly above the base plate. The four corners of the bottom of the fixed seat are fixedly connected to the upper surface of the base plate by vertically arranged telescopic rods, and the fixed seat and the base plate are also connected by a lifting drive mechanism. The lifting drive mechanism comprises a threaded transmission block, a movable plate, a first side plate, a second side plate, a drive assembly, a first sliding assembly, and a second sliding assembly. The first sliding assembly and the drive assembly are both fixedly mounted on the upper surface of the base plate, and are spaced apart along the length of the base plate. The movable end of the first sliding assembly is fixedly connected to the lower surface of the movable plate. The threaded transmission block is fixed to the upper side of the movable plate, and the first side plate is vertically fixed to the side of the movable plate. The drive end of the drive assembly forms a threaded connection with the threaded transmission block. The second side plate is vertically fixed to the bottom of the fixed base at a position corresponding to the first side plate. The first side plate and the fixed base are slidably connected via the second sliding assembly.

[0005] Furthermore, the first sliding component includes a first slide rail and a first slider; the first slide rail is a long strip structure and is fixedly installed on the upper surface of the base plate in the transverse direction; the number of the first sliders is 2-4, and they are evenly spaced along the length direction of the first slide rail at the bottom of the moving plate, and each first slider is slidably connected to the first slide rail.

[0006] Furthermore, limit blocks are fixedly installed at both ends of the first slide rail. The cross-sectional dimension of the limit blocks is larger than that of the first slide rail, and they are used to limit the sliding stroke of the first slider.

[0007] Furthermore, the drive assembly includes a motor and a threaded rod; the motor is fixed to the upper surface of the base plate via a motor mounting bracket, the output shaft of the motor is coaxially fixedly connected to one end of the threaded rod via a coupling, and the other end of the threaded rod is threaded through the interior of the threaded transmission block along the axial direction.

[0008] Furthermore, the motor is a servo motor; the axis of the threaded rod is parallel to the axis of the first slide rail, ensuring that the moving plate moves smoothly along a straight line.

[0009] Furthermore, the second sliding assembly includes a second slide rail and a second slider; the second slide rail is inclined and fixedly installed on the outer wall of the first side plate; two second sliders are slidably sleeved on the outer wall of the second slide rail along the length direction of the second slide rail, and each second slider is fixedly connected to the side of the second side plate facing the first side plate by bolts.

[0010] Furthermore, it also includes a scale for monitoring the lifting height of the fixed base, a first mounting plate, an indicator, and a second mounting plate; the second mounting plate is vertically fixed to the edge side of the bottom of the fixed base, and the lower part of the outer wall of the second mounting plate is fixed to the indicator by screws, the pointing direction of the indicator is opposite to the scale surface of the scale; the first mounting plate is vertically fixed to the upper surface of the base plate corresponding to the position of the second mounting plate, the scale is vertically set and fixedly installed on the outer wall of the first mounting plate; the gap between the scale surface of the scale and the indicator is 5mm-10mm, and the gap between the side of the fixed base and the edge of the scale is 7mm-12mm.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: like Figure 1-4 As shown, the present invention proposes an adaptive power supply device, which includes a horizontally arranged base plate 3 and a fixed seat 12 located directly above the base plate 3. The four corners of the bottom of the fixed seat 12 are fixedly connected to the upper surface of the base plate 3 by vertically arranged telescopic rods 5, and the fixed seat 12 and the base plate 3 are also connected by a lifting drive mechanism. The lifting drive mechanism consists of a threaded transmission block 8, a movable plate 13, a first side plate 14, a second side plate 16, a drive assembly, a first sliding assembly, and a second sliding assembly. The first sliding assembly and the drive assembly are both fixedly installed on the upper surface of the base plate 3, and are spaced apart along the length of the base plate 3. The movable end of the first sliding assembly is fixedly connected to the lower surface of the movable plate 13. The threaded transmission block 8 is fixed to the upper side of the movable plate 13, and the first side plate 14 is vertically fixed to the side of the movable plate 13. The drive end of the drive assembly forms a threaded engagement with the threaded transmission block 8. The second side plate 16 is vertically fixed to the bottom of the fixed base 12 at the position corresponding to the first side plate 14. The first side plate 14 and the fixed base 12 are slidably connected through the second sliding assembly.

[0022] It should be noted that the mounting base 12 is used to support the power module mounting base 12, and the power module can be fixed to the mounting base 12 through the pre-drilled mounting holes and matching bolts; the telescopic rods 5 at the four corners of the bottom of the mounting base 12 are symmetrically distributed, which can play a guiding and auxiliary stabilizing role during the lifting and lowering of the mounting base 12, and prevent the mounting base 12 from tilting; and the mounting base 12 and the base plate 3 are also connected by a lifting drive mechanism to provide stable power for the lifting and lowering of the mounting base 12.

[0023] The moving end of the first sliding component is fixedly connected to the lower end face of the moving plate 13, providing guidance for the lateral movement of the moving plate 13; the transmission end of the drive component forms a threaded engagement with the threaded transmission block 8 to provide lateral movement power for the moving plate 13. The movement of the moving plate 13 can drive the first side plate 14 to move as well, and through the second sliding component, drive the second side plate 16 to rise and fall, so that the lateral movement of the moving plate 13 can be converted into the vertical rising and falling movement of the fixed seat 12.

[0024] In this embodiment, the first sliding component includes a first slide rail 6 and a first slider 7; the first slide rail 6 is a long strip structure and is fixedly installed on the upper surface of the base plate 3 in the transverse direction; the number of first sliders 7 is 2-4, and they are evenly spaced along the length direction of the first slide rail 6 at the bottom of the moving plate 13, and each first slider 7 is slidably connected to the first slide rail 6.

[0025] It should be noted that the first slide rail 6 serves as a sliding guide reference; the number of the first sliders 7 is 2-4, and this application prefers two. Its multi-slider design can distribute the weight load of the moving plate 13, avoid excessive force on a single slider causing jamming, and ensure that the moving plate 13 moves along the first slide rail 6.

[0026] In this embodiment, limit blocks 10 are fixedly installed at both ends of the first slide rail 6. The cross-sectional dimension of the limit block 10 is larger than that of the first slide rail 6, and is used to limit the sliding stroke of the first slider 7.

[0027] It should be noted that the limiting blocks 10 on both sides prevent the first slider 7 from slipping off from both ends of the first slide rail 6.

[0028] In this embodiment, the drive assembly includes a motor 11 and a threaded rod 9. The motor 11 is fixed to the upper surface of the base plate 3 by a motor mounting seat. The output shaft of the motor 11 is coaxially fixedly connected to one end of the threaded rod 9 by a coupling. The other end of the threaded rod 9 passes through the interior of the threaded transmission block 8 along the axial thread.

[0029] It should be noted that the motor 11, as the power source, can drive the threaded rod 9 to rotate synchronously. Through the threaded engagement, the rotational motion of the threaded rod 9 is converted into the transverse linear motion of the threaded transmission block 8, which in turn drives the moving plate 13 to move along the first slide rail 6.

[0030] In this embodiment, the motor 11 is a servo motor and is equipped with a speed controller, which can realize stepless speed regulation; the axis of the threaded rod 9 is set parallel to the axis of the first slide rail 6 to ensure that the moving plate 13 moves smoothly along a straight line.

[0031] It should be noted that the axis of the threaded rod 9 is set parallel to the axis of the first slide rail 6 to ensure that the moving plate 13 moves smoothly along a straight line.

[0032] In this embodiment, the second sliding assembly includes a second slide rail 17 and a second slider 18; the second slide rail 17 is inclined and fixedly installed on the outer wall of the first side plate 14; two second sliders 18 are slidably sleeved on the outer wall of the second slide rail 17 at intervals along the length direction of the second slide rail 17, and each second slider 18 is fixedly connected to the side of the second side plate 16 facing the first side plate 14 by bolts.

[0033] It should be noted that the tilt angle of the second slide rail 17 is determined according to the design lifting stroke of the fixed base 12; when the moving plate 13 moves laterally, the first side plate 14 will also move synchronously, and the second slide rail 17 moves with the first side plate 14 and slides relative to the second slider 18. Since the second slide rail 17 is tilted, it will exert a vertical force on the second slider 18 during the relative sliding process, thereby driving the second side plate 16 and the fixed base 12 to achieve vertical lifting.

[0034] Example 2: According to the appendix Figure 1 and 4As shown, based on Embodiment 1, it also includes a scale 1 for monitoring the lifting height of the fixed base 12, a first mounting plate 2, an indicator 4, and a second mounting plate 15; the second mounting plate 15 is vertically fixed to the edge side of the bottom of the fixed base 12 and rises and falls synchronously with the fixed base 12, and the lower side of the outer wall of the second mounting plate 15 is fixed to the indicator 4 by screws, and the pointing direction of the indicator 4 is opposite to the scale surface of the scale 1; the first mounting plate 2 is vertically fixed to the position of the upper surface of the base plate 3 corresponding to the position of the second mounting plate 15, and the scale 1 is vertically set and fixedly installed on the outer wall of the first mounting plate 2 as the fixed base of the scale 1.

[0035] In this utility model, when the fixed base 12 is raised or lowered, the second mounting plate 15 drives the indicator 4 to move synchronously. The indicator 4 points to the corresponding scale of the scale 1. The user can intuitively obtain the real-time height of the fixed base 12 by reading the scale, and realize the height control.

[0036] As the fixed base 12 moves up and down synchronously, it is used to indicate the corresponding scale on the scale 1, and the scale range of the scale 1 covers the designed lifting stroke of the fixed base 12, so as to intuitively display the real-time height of the fixed base 12.

[0037] It should be noted that the gap between the scale surface of the ruler 1 and the indicator 4 is 5mm-10mm. This gap design can prevent the two from interfering with each other during the lifting and lowering of the fixed base 12, ensuring that the indicator 4 moves smoothly. At the same time, the gap between the side of the fixed base 12 and the edge of the ruler 1 is 7mm-12mm, further ensuring that there is no risk of collision when the fixed base 12 is lifted and lowered.

[0038] Working principle: When the servo motor 11 is started, the output shaft of the motor 11 drives the threaded rod 9 to rotate through the coupling. Since the threaded rod 9 is threadedly engaged with the threaded transmission block 8, it drives the moving plate 13 to move laterally along the first slide rail 6. When the moving plate 13 moves laterally, the first side plate 14 on its side moves laterally simultaneously, and the inclined second slide rail 17 fixed on the first side plate 14 moves along with it. Since the second slide rail 17 is slidably engaged with the second slider 18 fixed on the second side plate 16, the lateral movement of the second slide rail 17 is converted into a vertical force through the second slider 18. When the moving plate 13 moves closer to the motor, the second slide rail 17 pushes the second slider 18 to slide upward, thereby driving the fixed seat 12 to rise. When the motor 11 reverses, the moving plate 13 moves away from the motor, and the second slide rail 17 pulls the second slider 18 to slide downward, driving the fixed seat 12 to fall.

[0039] Furthermore, during the lifting and lowering process of the fixed base 12, the telescopic rods 5 at the four corners of its bottom extend and retract synchronously, serving as a vertical guide.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
