[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the motor coil removal device of the embodiment of the utility model includes a base 1, a column 2, a hook 3, a mounting seat 4, a first clamp 5 and a second clamp 6. The column 2 is arranged on the base 1, and the hook 3 is connected to the column 2 through a lifting assembly so that the hook 3 can move in the vertical direction, and the hook 3 is used to hook the motor coil. The mounting seat 4 is arranged on the base 1 for installing the motor, and the first clamp 5 and the second clamp 6 are arranged on the mounting seat 4 at intervals along the first horizontal direction. Each of the first clamp 5 and the second clamp 6 can be connected to the base 1 in an adjustable position along the first horizontal direction, so that the first clamp 5 and the second clamp 6 cooperate to clamp and fix the motor in the first horizontal direction, wherein the first horizontal direction can be the width direction of the base (such as Figure 1 and Figure 2 shown).

[0025] During use, the motor coil removal device of the utility model embodiment first adjusts the position of the first clamp 5 and the second clamp 6 relative to the mounting seat 4 along the first horizontal direction to increase the distance between the first clamp 5 and the second clamp 6, so that there is enough space between the first clamp 5 and the second clamp 6 to place the motor with the coil to be removed. Then the motor with the coil to be removed is placed between the first clamp 5 and the second clamp 6, and the position between the first clamp 5 and the second clamp 6 relative to the mounting seat 4 is adjusted so that the first clamp 5 and the second clamp 6 clamp the motor in the first horizontal direction. After that, the height of the hook 3 is adjusted downward by the lifting assembly so that the hook 3 is hooked on the coil of the motor, and finally the height of the hook 3 is adjusted upward by the lifting assembly so that the hook 3 directly pulls the coil of the motor upward and separates the coil from the housing of the motor. Compared with the manual removal of the heated coil in the related art, the motor coil removal device of the utility model embodiment greatly reduces the labor intensity of the workers, and can also avoid the risk of harmful substances generated by heating causing harm to the employees, thereby improving the safety of disassembly.

[0026] Therefore, the motor coil removal device of the embodiment of the utility model has the advantages of low labor intensity and high disassembly safety.

[0027] In some embodiments, the mounting seat 4 is rotatably connected to the base 1 via a first rotation axis 7 extending along the vertical direction.

[0028] For example, Figure 3 As shown, when the motor is clamped and fixed on the mounting base 4 by the first clamping member 5 and the second clamping member 6, since the motor can no longer move relative to the mounting base 4, the position of the motor can be adjusted by rotating the mounting base 4, so that the hook 3 can be smoothly and quickly hooked on the coil of the motor, which greatly improves the disassembly efficiency of the motor coil removal device of the utility model embodiment.

[0029] In some embodiments, the mounting seat 4 has a dovetail groove 401 extending along the first horizontal direction, the first clamping member 5 has a first sliding portion 501 that slides with the dovetail groove 401 along the first horizontal direction, and the second clamping member 6 has a first horizontal direction that slides with the dovetail groove 401.

[0030] For example, Figures 3 to 5 As shown, when the position of the first clamping member 5 is adjusted in the first horizontal direction, the position of the first clamping member 5 can be adjusted by sliding the first sliding portion 501 in the first horizontal direction. It can be understood that the dovetail groove 401 on the mounting seat 4 can limit the first sliding portion 501 in the up-down direction to prevent the motor from being separated from the mounting seat 4 when the hook 3 is hoisting the motor coil, making the structure simple and easy to install. Similarly, when the position of the second clamping member 6 is adjusted in the first horizontal direction, the position of the second clamping member 6 can be adjusted by sliding the second sliding portion 601 in the first horizontal direction. The dovetail groove 401 on the mounting seat 4 can limit the second sliding portion 601 in the up-down direction to prevent the motor from being separated from the mounting seat 4 when the hook 3 is hoisting the motor coil, making the structure simple and easy to install.

[0031] In some embodiments, the first clamping member 5 has a first connecting hole extending along the first horizontal direction, and the second clamping member 6 has a second connecting hole extending along the first horizontal direction. The first clamping member 5 and the second clamping member 6 clamp and fix the motor between the first clamping member 5 and the second clamping member 6 by a fastener 8 passing through the first connecting hole and the second connecting hole.

[0032] Specifically, Figure 4 As shown, after the position adjustment of the first clamping member 5 and the second clamping member 6 is completed, the positions of the first clamping member 5 and the second clamping member 6 are fixed by the fastener 8, so that the first clamping member 5 and the second clamping member 6 are conveniently fixed.

[0033] Optionally, the fastener 8 covers the screw rod 801 and the nut 802 , and the screw rod 801 passes through the first connecting hole and the second connecting hole and is threadedly connected with the nut 802 , so that the fastener 8 has a simple structure and is easy to adjust.

[0034] In some embodiments, the number of the first connection holes is two, and the two first connection holes are spaced apart on both sides of the first clamping member 5 along the second horizontal direction. The number of the second connection holes is two, and the two second connection holes are spaced apart on the side of the first clamping member 5 along the second horizontal direction, wherein the first horizontal direction is perpendicular to the second horizontal direction, and the second horizontal direction can be the length direction of the base 1 (such as Figure 1 and Figure 2 shown).

[0035] The motor coil removal device of the embodiment of the utility model is provided with two first connecting holes and two second connecting holes, and two fasteners 8 can be used to fasten the first clamping member 5 and the second clamping member 6, so that the first clamping member 5 and the second clamping member 6 are subjected to uniform force in the second horizontal direction, so as to improve the stability of the first clamping member 5 and the second clamping member 6 in clamping and fixing the motor.

[0036] In some embodiments, the first clamping member 5 has a first arc-shaped groove 502 , the second clamping member 6 has a second arc-shaped groove 602 , and the opening of the first arc-shaped groove 502 and the opening of the second arc-shaped groove 602 are arranged opposite to each other along the first horizontal direction.

[0037] like Figure 4 As shown, the motor coil removal device of the embodiment of the utility model is provided with a first arc-shaped groove 502 on the first clamping member 5 and a second arc-shaped groove 602 on the second clamping member 6. When the motor is clamped and fixed, the first arc-shaped groove 502 and the second arc-shaped groove 602 fit with the outer wall surface of the motor to increase the contact area between the first clamping member 5 and the second clamping member 6 and the motor, thereby increasing the force area of ​​the first clamping member 5 and the second clamping member 6 when clamping the motor, thereby improving the clamping stability of the first clamping member 5 and the second clamping member 6.

[0038] In some embodiments, the lifting assembly includes a wire rope 9, a movable pulley 10, a fixed pulley 11, a wire drum 12, and a driving motor 13. The hook 3 is connected to the movable pulley 10, the fixed pulley 11 is arranged at the top of the column 2, the wire drum 12 is rotatably arranged on the base 1, the driving motor 13 is connected to the wire drum 12 to drive the wire drum 12 to rotate, one end of the wire rope 9 is connected to the top of the column 2, and the other end of the wire rope 9 is connected to the wire drum 12 after passing through the movable pulley 10 and the fixed pulley 11 in sequence, and the wire drum 12 is used to retract or release the wire rope 9 to change the height of the movable pulley 10.

[0039] Specifically, the drive motor 13 retracts the wire rope 9 by controlling the rotation of the wire drum 12, so that the hook 3 moves upward. The drive motor 13 releases the wire rope 9 by controlling the rotation of the wire drum 12, so that the hook 3 moves downward by its own weight, thereby making it convenient to adjust and control the hook 3 in the up and down directions.

[0040] Alternatively, if Figure 2 As shown, the motor coil removal device of the utility model embodiment also includes a second rotating shaft 14, which is rotatably arranged on the base 1, the wire drum 12 is mounted on the second rotating shaft 14, and the output shaft of the driving motor 13 is connected to the second rotating shaft 14 through a bevel gear pair.
