However, the fan frequency changer is usually large in size and heavy in weight, and faces many challenges in the process of carrying and installing.

[0003] The existing carrying mode mostly depends on the traditional forklift or manual carrying tool. When using the forklift to carry, due to the irregular shape of the fan frequency changer and the high stability requirement in the carrying process, it is difficult to accurately control the position of the frequency changer in the operation process of the forklift, which is easy to cause the collision between the frequency changer and the surrounding equipment, resulting in the damage of the equipment. At the same time, the forklift requires a large operation space, and in some narrow space working places, such as the equipment-intensive machine room or the inside of the workshop, the forklift cannot normally work.

[0004] Although the manual carrying tool, such as the hydraulic trolley, solves the problem of space limitation to a certain extent, due to the large weight of the fan frequency changer, manual carrying needs to consume a large amount of manpower, which is high in labor intensity and low in carrying efficiency. In addition, manual carrying cannot guarantee the stability in the carrying process, and the frequency changer is easy to tilt or even fall, which not only damages the equipment, but also threatens the safety of the operator.

[0032] The sub-clamp 10 is provided with a clamping telescopic motor 13, and the inner end of the clamping telescopic motor 13 is provided with a clamping head;

[0033] The right end of the tray 6 is symmetrically provided with mounting blocks, and the mounting blocks are provided with limiting telescopic motors 11; when the two limiting telescopic motors 11 are extended, the right side of the tray 6 is blocked, thereby limiting the movement;

[0034] The right upper part of the bracket 4 is provided with three independently controlled pushing telescopic motors 12, and the fan frequency converter is installed on the tray 6 and can be pushed to the right by the pushing telescopic motor 12;

[0035] Working principle:

[0036] The bottom of the base 1 is provided with a driving wheel 2, and the driving motor in the base 1 is in transmission connection with the driving wheel 2. Through the rotation of the driving motor, power is transmitted to the driving wheel 2, and the driving wheel 2 rotates to realize the movement of the carrying tool on the ground, thereby facilitating the carrying of the fan frequency converter to the specified position.

[0037] The chain hoist 3 on the top of the base 1 is provided with the bracket 4. When the chain hoist works, the movement of the chain drives the bracket 4 to move up and down in the vertical direction, thereby adjusting the height position of the fan frequency converter placed on the bracket 4 to adapt to the carrying demand or installation position of different heights.

[0038] The main clamp 7 is provided with a transverse adjusting device 8, which comprises a transverse driving motor and a transverse adjusting screw rod penetrating through the main clamp 7. When the transverse driving motor works, the transverse adjusting screw rod is driven to rotate.

[0039] The longitudinal adjusting device 9 of the bottom of the sub-clamp 10 comprises a sliding frame, a longitudinal driving motor and a longitudinal adjusting screw rod. The sliding frame is inserted into the sliding groove of the main clamp 7 and fixed with the sub-clamp 10, and the longitudinal adjusting screw rod is screwed on the sliding frame. The longitudinal driving motor drives the longitudinal adjusting screw rod to rotate, the rotation of the screw rod drives the sliding frame to move forward and backward in the sliding groove of the main clamp 7, and then drives the sub-clamp 10 to move in the front and back direction, so as to adjust the longitudinal position of the sub-clamp 10 and further improve the positioning and clamping precision of the fan frequency converter;

[0040] The clamping telescopic motor 13 is installed on the sub-clamp 10. When working, the clamping head arranged at the inner end of the clamping telescopic motor 13 can clamp or loosen the fan frequency converter according to the telescopic action of the motor, so as to reliably fix and release the fan frequency converter, and facilitate carrying and installation.

[0041] The limiting telescopic motor 11 is arranged in the mounting block of the right end of the tray 6 in a front and back symmetry mode. When the two limiting telescopic motors 11 are extended, the right side of the tray 6 is blocked, the moving range of the fan frequency converter on the tray 6 to the right is limited, a limiting effect is achieved, and the fan frequency converter is prevented from sliding off the tray 6 during carrying.

[0042] The three independently controlled pushing telescopic motors 12 are installed on the right side of the upper part of the bracket 4. When the fan frequency converter is installed on the tray 6, the pushing telescopic motor 12 is extended to push the fan frequency converter to the right, so as to push the fan frequency converter out of the tray 6 and assist in completing the carrying work.
