Description

Technical Field

[0001] The utility model belongs to the technical field of frequency converter installation, in particular to a three-dimensional movable support for frequency converter installation. Background Art

[0002] The inverter is an electric power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. When the inverter is installed in the air on the wall, it needs to be supported by a bracket.

[0003] Among them, after searching, it was found that there is an application number CN202320031462.4, which discloses a frequency converter mounting bracket, including a mounting bracket and a locking bolt. A bidirectional screw is rotatably connected at the middle position of the inner side of the mounting bracket, and a bidirectional screw, a side clamping plate and a threaded joint are arranged. The threaded joint is used to enable the ferrule to be installed on the side of the frequency converter, and the transmission block can drive the transmission rod to rotate by rotating the bidirectional screw, so that the transmission rod can drive the side clamping plate to move, and at the same time, the upper and lower ends of the side clamping plate can be limited by the action of the arranged limit slider, so that the positioning clamping plate can drive the clamp head to be inserted The ferrule is inserted into the card sleeve, so that the inverter can be quickly disassembled and assembled. The adjusting screw, the back top plate and the pressure plate are arranged, and the position of the back top plate can be adjusted by rotating the adjusting screw, so that the back top plate can be closely fitted with the back of the inverter, making the installation of the inverter more stable. At the same time, through the connection between the pressure plate and the electrical appliance, when the electrical appliance vibrates, the vibration force can be transmitted to the damping spring through the pressure plate, so that the vibration force generated by the electrical appliance can be absorbed by the damping spring, thereby reducing the vibration of the inverter and improving the overall stability of the inverter after installation and the service life of the inverter.

[0004] However, after research, it was found that: the device cannot lift the inverter, cannot adjust the angle of the inverter, cannot provide support for the inverter in a suspended position, and the use effect is not good enough. Other external lifting tools are required to lift the device and the inverter at the same time. During the lifting process, the device cannot provide a guide. During the lifting process, the inverter and the device will rotate at the same time, causing danger. Therefore, a new device is provided to solve this problem. Utility Model Content

[0008] Wherein, the lifting mechanism includes a bracket, a winch, a servo electric cylinder A, a lifting frame, a servo electric cylinder B, a guide frame and a connecting frame. The bracket is fixedly installed on one side above the support plate, and a winch is installed on one side above the bracket.

[0009] Among them, a limit frame A is fixedly installed on one side below the connecting frame, and a limit frame B is slidably connected to the other side below the connecting frame through a slide rail. Electric cylinders are symmetrically installed above the limit frame A, and the ends of the electric cylinders are connected to the limit frame B.

One side of the limit frame A is symmetrically connected to a strap B, and one side of the limit frame B is symmetrically connected to a strap A, and the strap A and the strap B are connected through a rope tightener.

[0012] 2. In the utility model, the heavy-load electric turntable adjusts the angle of the support plate, and then adjusts the angle of the inverter. The servo electric cylinder A extends and retracts to drive the lifting frame to rotate, adjust the highest point position of the lifting frame, and then adjust the upward height of the inverter, which is more flexible to use.

[0013] 3. In the utility model, the frequency converter is clamped between the limit frame A and the limit frame A, and the corresponding binding straps B and A are respectively tightened and bound together through a rope tightener, so that the limit frame B and the limit frame A are more firmly fixed, and at the same time, the frequency converter is limited and fixed from the other two sides, which has a better fixing effect on the frequency converter.

While the lifting frame 104 rotates, the servo electric cylinder B1042 is extended and retracted, driving the guide frame 1043 to rotate, so that the guide frame 1043 is always vertical to the ground to guide the inverter. The heavy-load electric turntable 1021 works to adjust the angle of the support plate 102, and then adjust the angle of the inverter, and move the inverter to the installation position.

Then, clamp the limit frame A201 on one side of the inverter, and the electric cylinder 2021 retracts and pulls the limit frame A201 to the other side of the inverter. The inverter is clamped between the limit frame A201 and the limit frame A201 to fix the inverter. Tighten and bind the corresponding straps B2031 and A203 together through the rope tightener, so that the limit frame B202 and the limit frame A201 are fixed more firmly. At the same time, the inverter is limited and fixed from the other two sides, which has a better fixing effect on the inverter. Then the servo electric cylinder A1032 retracts and drives the lifting frame 104 to rotate, and the highest point of the lifting frame 104 is The position is adjusted, and then the upward moving height of the inverter is adjusted. While the lifting frame 104 rotates, the servo electric cylinder B1042 extends and retracts, driving the guide frame 1043 to rotate, so that the guide frame 1043 is always vertical to the ground. Finally, the winch 1031 works, driving its matching rope to reel in, pulling the connecting frame 2 to move upward, and the pulley 1041 reduces the friction between the rope and the lifting frame 104, so that the connecting frame 2 moves upward more smoothly.
