Description

Technical Field

[0001] The invention belongs to the technical field of variable frequency motors, and in particular relates to a variable frequency motor that is convenient for hoisting and transfer. Background Art

[0002] A variable frequency motor is a motor that can change its speed by adjusting the power supply frequency. It is usually used in conjunction with a frequency converter to achieve precise control of the motor's operating speed, torque, and power. It supports soft starting and stepless speed regulation, reduces mechanical shock, and thus extends equipment life. It is suitable for scenarios that require frequent starting, stopping, and speed changes.

[0003] The variable frequency motors currently on the market have the following problems when applied:

[0004] 1. When transferring traditional variable frequency motors, they are usually bound and transferred by binding ropes and a single lifting ring structure. During transportation, they can only be supported by one point. During transfer, they are not stable and there are installation risks. Therefore, the transfer hoisting is relatively stable.

[0005] 2. When using most variable frequency motors, the wiring holes outside the junction box often need to be connected to the wiring harness. Since there is no structure installed to clamp and fix the wiring harness, the wiring harness is prone to loosening after long-term use. Therefore, there is no structure to restrain the wiring harness during use.

[0006] 3. When most variable frequency motors are used, the base and the mounting base are usually directly fixed and connected. When the variable frequency motor is used for a long time, a large amount of heat will be generated between the mounting base and the base. Excessive temperature can easily affect the service life of the variable frequency motor. Therefore, it is not convenient to dissipate heat during application. Summary of the Invention

[0043] The working principle of the variable frequency motor that is convenient for lifting and transfer: when using the device, it is first necessary to move the device body to a position with the help of transportation. After moving to a suitable position, it can be placed on a plane. In order to facilitate the lifting of the variable frequency body, the connecting plate 8 and the metal plate 9 are connected on the side of the base, and a storage box 11 is installed on the side of the connecting plate 8. The storage box 11 is connected to the top cover 12 through a rotating shaft, and the side of the top cover 12 is connected to the magnetic plate 10, and a fixing block 13 and a shaft rod 14 are installed inside the storage box 11. The outside of the shaft rod 14 is connected to the shaft sleeve 15, and the outside of the shaft sleeve 15 is connected to the lifting ring 16. When the variable frequency body needs to be transferred, first rotate the top of the storage box 11 in the opposite direction. The top cover 12 of the top is rotated by the shaft 14 to rotate the ring 16 from the inside of the storage box 11 to the appropriate position. Then the staff takes out the binding rope and passes it through the inside of the multiple sets of rings 16, and passes it through the device body to connect it with the hook. In this way, when transferring, due to the connection of multiple sets of rings 16 structures, the connection surface is increased, which makes the transfer more convenient, stable and safe. After the machine base 1 is moved to the designated position, the binding rope is loosened, and the staff rotates the top cover 12 in the opposite direction to adsorb the magnetic plate 10 on the outside of the metal plate 9 by magnetic force. In this way, the ring 16 can be installed in the inside of the storage box 11, and then the fastener is taken out and passed through the mounting hole 7 inside the mounting plate 6 to connect the mounting plate 6 with the mounting plate 6.

Due to the installation of the elevated structure, by increasing the distance between the machine base and the ground, the heat accumulation at the bottom due to the narrow space is avoided, so that heat dissipation is convenient during application, thereby extending the service time. Then the staff connects the wiring harness to the wiring hole 5 outside the junction box 4. In order to facilitate the restraint and fixation of the wiring harness, a threaded hole 21 is opened on the outside of the wiring hole 5, and a threaded block 22 is threadedly connected to the inside of the threaded hole 21, wherein the screw The side of the pattern block 22 is connected to the rod body 23, and the rod body 23 is connected to the threaded rod 25 through the limit ring 24, and the side plate 29 is sleeved on the outside of the rod body 23, and the side of the side plate 29 is connected to the strip plate 27.
