Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] See Figures 1 - 4 As shown, in the embodiment of the present invention, a transfer device for a frequency converter power module is proposed, including a forklift 1. The forklift 1 is provided with a liftable fork arm 2. The forklift 1 can adopt an existing electric forklift 1, which is a mature product. Among them, the fork arm 2 can be driven to perform ascending or descending operations. Specifically, a tooling 3 is detachably installed on the fork arm 2. The tooling 3 includes a frame structure 31 installed on the fork arm 2 through bolts. The side of the frame structure 31 away from the forklift 1 has an opening 32. A plurality of rotatable first rollers 33 are evenly distributed on the frame structure 31 along the length direction. The entire tooling 3 is detachably installed on the fork arm 2 through bolts. Thus, the tooling 3 can be disassembled when the frequency converter power module is not being transferred, and the normal use of the forklift 1 can be restored.

[0027] Specifically, after the frame structure 31 is installed on the fork arm 2, the frequency converter power module is loaded from the opening 32 and moved along the first rollers 33 to reduce the friction force and facilitate the position movement. After the movement is in place, it is necessary to further clamp and limit the frequency converter power module to avoid the risk of falling during the lifting process.

[0028] Specifically, two screws 34 parallel to the first rollers 33 are installed at intervals on the frame structure 31. A first baffle 35 and a second baffle 36 are sleeved on the two screws 34 at intervals. The length directions of the first baffle 35 and the second baffle 36 are parallel to the length direction of the frame structure 31. The first baffle 35 and the second baffle 36 are slidably arranged on the first rollers 33. Wing nuts 37 are sleeved on the two screws 34 outside the first baffle 35 and the second baffle 36. When the frequency converter power module moves in place, the wing nuts 37 are rotated so that the first baffle 35 and the second baffle 36 move towards the frequency converter power module to achieve clamping and positioning.

[0029] After installing the inverter power module, it is transported to the assembly position by forklift 1 and lifted to the installation height by raising the fork arms 2. Then, loosen the wing nut 37 and push the inverter power module to the installation position to complete the installation. Thus, the process of transporting and lifting the inverter power module is completed, avoiding problems such as the risk of dropping and high labor intensity caused by manual operation.

[0030] Specifically, the first baffle 35 and the second baffle 36 are slidably engaged with multiple corresponding first rollers 33, and further, the sliding of the first baffle 35 and the second baffle 36 is guided by the first rollers 33, so as to ensure that the first baffle 35 and the second baffle 36 will not be jammed during the sliding process.

[0031] Meanwhile, in order to ensure that there is no risk of sliding when the first baffle 35 and the second baffle 36 clamp the inverter power module, rubber pads 38 are provided on the opposite sides of the first baffle 35 and the second baffle 36; the rubber pads 38 play an anti-slip role and protect the inverter power module when clamping it.

[0032] Specifically, the first baffle 35 and the second baffle 36 are limited during the sliding process, and at the same time, the structural strength is ensured. Bent structures 39 are provided at both ends of the first baffle 35 and the second baffle 36.

[0033] Specifically, a rotating bracket 4 is rotatably installed on the frame structure 31 at the opening 32. At least one second roller 5, a third roller 6, and a fourth roller 7 with diameters decreasing in sequence from the opening 32 are rotatably installed on the rotating bracket 4. The function of the rotating bracket 4 is to guide the inverter power module during the feeding or discharging process, and the second roller 5, the third roller 6, and the fourth roller 7 with diameters decreasing in sequence are used to realize the guiding function in the oblique direction.

[0034] In order to maintain good guidance during the process of moving the inverter power module from the rotating bracket 4 to the frame structure 31, the diameters of the first roller 33 and the second roller 5 are the same; specifically, the diameters of the first roller 33, the second roller 5, the third roller 6, and the fourth roller 7 are limited to ensure a smooth sliding and guiding process. Specifically, the diameters of the first roller 33 and the second roller 5 are 50 mm, the diameter of the third roller 6 is 38 mm, and the diameter of the fourth roller 7 is 20 mm.

[0035] Among them, the frame structure 31 includes a bearing bottom plate 311 and side plates 312 fixed on both sides of the bearing bottom plate 311. One end of the two side plates 312 is fixed with a limiting plate 313, and the other end of the two side plates 312 is the opening 32. A groove-shaped structure is formed by enclosing the bearing bottom plate 311, the side plates 312, and the limiting plate 313, so as to facilitate having a certain blocking effect and ensure safety during the sliding process of the inverter power module.

[0036] Meanwhile, the bearing bottom plate 311 and the rotating bracket 4 are connected by two hinges 8 arranged at intervals, and the angle of the rotating bracket 4 can be adjusted within a relatively large rotation angle range to adapt to the height of the feeding position and the height of the discharging position of the inverter power module specifically.

[0037] Specifically, a limiting and engaging structure is provided between the rotating bracket 4 and the bearing bottom plate 311. The limiting and engaging structure can be a hook, a limiting pin, a telescopic rod or other structures, which are used to position the state after the relative rotation angle. Specifically, the limiting and engaging structure may not be adopted, and the rotating bracket 4 can be directly supported.
