[0043] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0044] See also Figures 1 to 5 The present embodiment provides a motor-assisted replacement device for a ring-threading trolley, comprising a base frame 1, a lifting mechanism 2, a slide feed mechanism 3 and a control cabinet 4. The lifting mechanism 2 is vertically arranged on the base frame 1, and the slide feed mechanism 3 is vertically arranged on the top of the lifting mechanism 2 so as to be movable up and down. A limit assembly 5 which can be movable forward and backward is provided on the slide feed mechanism 3, and a groove matching the outer contour of the motor is provided on the limit assembly 5.

The combination of the two enables the limit assembly 5 to freely adjust the setting position in the space, and then the limit assembly 5 fits with the outer contour of the motor to be installed and disassembled through its own groove, thereby completing the auxiliary support of the motor.

[0046] The motor auxiliary replacement device of the circular trolley in this embodiment can flexibly adjust the spatial position of the limit component 5 through the jacking mechanism 2 and the slide feed mechanism 3, and support the motor to be installed and disassembled through the limit component 5, thereby overcoming the problem of difficulty in positioning and supporting the motor for a long time due to the small space when manually installing and disassembling the motor. While saving labor, it improves the installation and disassembly efficiency of the motor and avoids the safety risk of the motor accidentally falling and injuring people.

[0047] Preferably, in this embodiment, the control cabinet 4 is a PLC control cabinet.

More than three casters 13 are arranged at intervals at the bottom of the frame body 11. The pull rod 12 is obliquely arranged on the side of the frame body 11 and extends upward. Therefore, the motor auxiliary replacement device of this embodiment can also undertake the work of transporting the motor. Only by pulling the pull rod 12, the motor auxiliary replacement device with the motor placed can be moved to the motor maintenance position. It is no longer necessary to manually transport the motor, which reduces manpower and improves the safety of the motor transportation process.

[0049] Preferably, in this embodiment, there are four casters 13, and the four casters 13 are arranged in a rectangular shape.

[0050] Preferably, the caster 13 is a Fomar wheel. With the universal and dust-proof functions of the Fomar wheel, personnel can more conveniently change the moving direction of the chassis 11, and can adapt to an environment with more dust and ash accumulation.

The plurality of servo electric cylinders 21 are vertically arranged on the base frame 1 and are simultaneously connected to the control cabinet 4 by signals. The working ends of the plurality of servo electric cylinders 21 are vertically connected to the slide feed mechanism 3. The control cabinet 4 independently controls the plurality of servo electric cylinders 21 to adjust the tilt angle of the slide feed mechanism 3, so that after the motor is limited on the limit assembly 5, the installation angle can be flexibly adjusted to improve the installation efficiency.

[0052] Preferably, in this embodiment, the number of the servo electric cylinders 21 is three.

[0054] Preferably, the sliding plate 32 is detachably connected to the fixed plate 31, and there are multiple sliding plates 32. The limiting components 5 on the multiple sliding plates 32 can respectively match the outer contour of a motor of a certain specification. The motor auxiliary replacement device of this embodiment can realize the auxiliary installation and removal of motors of various specifications by replacing the sliding plates 32.

[0055] Preferably, see Figure 5 and Figure 6 A screw rod 33 is arranged parallel to the top surface of the fixed plate 31, and a slider is arranged at the bottom of the sliding plate 32. The slider can be reciprocatingly slidably sleeved on the screw rod 33, and a hand wheel 34 is arranged at one end of the screw rod 33.

[0058] Preferably, see Figure 5 and Figure 6 The position limiting assembly 5 includes a first profiling block 51, a second profiling block 52 and a third profiling block 53. The first profiling block 51 and the second profiling block 52 are provided with grooves respectively matching the left and right side contours of the front end of the motor, and the third profiling block 53 is provided with a groove matching the rear end contour of the motor. The first profiling block 51, the second profiling block 52 and the third profiling block 53 are circumferentially spaced on the slide feeding mechanism 3. When the position limiting assembly 5 fits the outer contour of the motor, the grooves of the first profiling block 51, the second profiling block 52 and the third profiling block 53 are respectively matched with the positions corresponding to the outer contour of the motor, thereby realizing the position limiting of the motor.
