Description

Technical Field

[0001] The utility model relates to the field of crane frequency converters, and particularly to a special crane frequency converter which is convenient to disassemble. Background Technique

[0002] A frequency converter is a power control device that applies frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's working power supply. The special crane frequency converter is used on cranes that adopt AC variable frequency speed regulation technology. Since the motor driven by the frequency converter has a hard mechanical characteristic and has the advantage of precise positioning, it will not show the phenomenon that the motor speed changes with the change of the load of the traditional crane, and can improve the productivity of the loading and unloading operation.

[0003] In a Chinese patent, a special crane frequency converter which is convenient to disassemble is disclosed, and its publication number is CN212799343U. In this special crane frequency converter which is convenient to disassemble, it includes a main body, a support member and a clamping member. A top support is fixed at the top end of the main body, a bottom support is fixed at the bottom end of the main body, a plurality of groups of protective members are fixed at the bottom end of the support member, a clamping member is fixed at the top end of the support member. The clamping member includes a cross bar, a vertical bar and a spring. Two groups of vertical bars are fixed at the bottom end of the cross bar, bumps are fixed at the bottom ends of the two groups of vertical bars, and springs are sleeved on the two groups of vertical bars. The support member includes a top plate, a vertical plate and a support plate. The top plate and the support plate are integrally formed on one side of the vertical plate. Through holes are opened at the four corners of the vertical plate. Two through holes adapted to the vertical bars are constructed in the top plate. A slot adapted to the bottom end of the bottom support and a plurality of groups of through holes are constructed at the top end of the support plate. A special crane frequency converter which is convenient to disassemble is convenient to disassemble and can prevent the loosening of the wire joints.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 4 shown, a special frequency converter for a crane that is easy to disassemble includes a frequency converter body 1. Fixing members 101 and connecting bolts 102 are arranged on the upper and lower sides of the frequency converter body 1 to connect it. The dust-proof net 2 on both side surfaces of the frequency converter body 1 cooperates with the gauze net 202 fixed inside it to perform dust-proof treatment on the frequency converter body 1. The maintenance board 3 on the back surface of the frequency converter body 1 is fixed by a clamping plate 301. The support plates 4 on the upper and lower sides of the frequency converter body 1 limit the frequency converter body 1 through the limit blocks 401 fixed on the surface, and an adjusting member 404 is arranged on one side surface of the support plate 4. The position of the adjusting member 404 is limited by the threaded hole 405 on the surface of the adjusting member 404 and the hand-tightening bolt 406. Connecting plates 501 are arranged on both sides of the fixing plate 5 on one side of the support plate 4 to facilitate fixing on other devices. An adjusting support member 6 is located between the support plate 4 and the fixing plate 5. The adjusting support member 6 is located between the support plate 4 and the fixing plate 5. The adjusting support member 6 is provided with a support member one 601. Through the fixing shaft one 602 fixed inside the support member one 601, the adjusting rod 603 rotating on the surface of the fixing shaft one 602 can, under the cooperation of the fixing shaft two 604 that can rotate inside the other end, adjust the support angle, and support members two 605 are arranged at both ends of the surface of the fixing shaft two 604, and the position is adjusted through the adjusting block 606 fixed on the upper surface of the support member two 605.

[0032] The dust-proof net 2 is connected through a fixing frame 201 fixed on the surface of the frequency converter body 1, and through holes with a groove-shaped structure are arranged on the surface of the dust-proof net 2.

[0033] Through the above technical solutions, the setting of the through holes can facilitate the heat dissipation inside the frequency converter body 1, cooperate with the setting of the gauze net 202 for dust prevention, and the fixing frame 201 connected by clamping can also facilitate the disassembly and assembly of the dust-proof net 2 for cleaning it.

[0034] Fixing grooves 402 are arranged on both sides of the surface of the support plate 4 to clamp the fixing members 101, so that the connecting bolts 102 can penetrate both of them.

[0035] Through the above technical solutions, the setting of the fixing grooves 402 enables the fixing members 101 to be just clamped inside them, facilitating their fixation through the connecting bolts 102.

[0036] One side surface of the support plate 4 slides on the surface of the fixed plate 5 through the fixed slider 403, and threaded holes 405 that cooperate with the adjusting member 404 are provided on the surface of the fixed plate 5 so that the hand-tightening bolt 406 can pass through.

[0037] Through the above technical solution, with the setting of the hand-tightening bolt 406, the adjusting member 404 can slide on the surface of the fixed plate 5, and the position of the adjusting member 404 is restricted in cooperation with the threaded holes 405, and the provided slider 403 can ensure that the sliding of the support plate 4 is more stable.

[0038] The support member one 601 fixed on the surface of the fixed plate 5 cooperates with the support member two 605 on the other side, so that the adjusting block 606 connected to the support member two 605 can slide on the surface of the support plate 4.

[0039] Through the above technical solution, with the sliding of the adjusting block 606, the support member two 605 can, with its assistance, adjust the angle between the adjusting rod 603 and the fixed plate 5, so as to facilitate the stable support of the support plate 4 by the adjusting rod 603.

[0040] During use, when the user uses a crane special frequency converter that is easy to disassemble, it is fixed at the position where work is required through the connecting plates 501 on both sides of the fixed plate 5. The hand-tightening bolt 406 is removed, so that the adjusting member 404 can slide on the surface of the fixed plate 5, and the position of the support plate 4 is limited in cooperation with the threaded holes 405. The frequency converter body 1 is connected to the surface of the support plate 4 through the fixing members 101 and the connecting bolts 102 at the upper and lower ends of the frequency converter body 1, and the adjusting support member 6 is used for support, so that the adjusting rod 603 can rotate around the fixed shaft one 602 and the fixed shaft two 604 to adjust the angle, and the adjusting block 606 can slide on the surface of the support plate 4 to provide stable support for the support plate 4. During the operation of the frequency converter body 1, the dust can be blocked by the dust-proof nets 2 on both sides in cooperation with the gauze nets 202 fixed inside, and when the frequency converter body 1 needs to be maintained, the inspection plate 3 can be removed to facilitate the maintenance inside.
