In the field of industrial automation, it is used for performance testing and maintenance of various industrial motors.

[0003] When the motor is overhauled on the existing motor overhaul platform, the motor overhaul platform can generally only be used for motors of one specification, and the applicability is not high. In addition, when the motor is disassembled for overhaul, the bearings on the motor shaft need to be disassembled manually with a handheld disassembly tool.

[0052] Example 3

[0053] On the basis of Example 1, the clamping assembly 4 includes a rotating rod 41, which passes through and is rotatably connected to the disassembly platform 13. Driven gears 42 are installed at both ends of the rotating rod 41. The driven gear 42 is meshed with the driving gear three 43. The driving gear three 43 is installed at the output end of the driving motor three 44. The driving motor three 44 is installed under the disassembly platform 13.

A driving cylinder 47 is installed at the end of the sliding groove 45 away from the disassembly platform 13. The working end of the driving cylinder 47 is connected to the vertical sliding groove 46, and the vertical sliding groove 46 is provided with a clamping structure 5.

[0054] The clamping structure 5 includes a main telescopic rod 51, which is installed at the top of a vertical slide groove 46. A mounting seat 52 is installed on the vertical slide groove 46.

The positioning terminal 58 and the plug plate 55 cooperate with each other.

[0055] The beneficial effects of the above technical solution are as follows: before the disassembly platform 13 is placed with the motor, the driving motor 3 44 drives the driving gear 3 43 to rotate forward, the driving gear 3 43 is meshed with the driven gear 42 for transmission, and the driven gear 42 drives the rotating rod 41 and the sliding groove 45 to rotate around the disassembly platform 13, so that the vertical sliding groove 46 is flush with the disassembly platform 13; after the disassembly platform 13 is placed with the motor, the driving motor 3 44 drives the driving gear 3 43 to rotate reversely, so that the sliding groove 45 and the vertical sliding groove 46 are reset, and then the driving cylinder 47 is started to push the vertical sliding groove 46 to move toward the center, and at the same time the main telescopic rod 51 works to drive the slider 53 to slide along the vertical sliding groove 46, so that the arc-shaped positioning plate 56 matches the side wall of the motor, and the secondary telescopic rod 57 synchronously follows the main telescopic rod 51 to ensure the limiting function of the positioning terminal 58 on the plug plate 55;

[0056] The present invention utilizes a driving motor three 44 and a driving gear three 43 to drive the driven gear 42 to rotate. This design can ensure the convenience of placing the motor on the disassembly platform 13, avoid damage to the clamping assembly 4 when the motor is placed, and enhance the human-computer interaction of the maintenance platform.

An electric screw rod 62 is rotatably connected in the screw groove 61, and an adjustment plate 63 is threadedly connected to the electric screw rod 62. The adjustment plate 63 and the screw groove 61 are relatively slidably connected. Slide rods 64 are penetrated and slidably connected at the four corners of the adjustment plate 63. One end of the slide rod 64 is connected to the four corners of the reaction force plate 65. A tensioning telescopic column 66 is installed at the center of the adjustment plate 63 near one side of the reaction force plate 65. The working end of the tensioning telescopic column 66 is connected to the center of the reaction force plate 65. The other end of the slide rod 64 is connected to a hollow flange 67. A bearing clamp structure 7 is installed on the hollow flange 67. A load-bearing telescopic column 68 is installed at the center of the other side of the adjustment plate 63, and a flexible sleeve is installed at the working end of the load-bearing telescopic column 68.

[0059] The bearing clamp structure 7 includes a flange base plate 71 , which is mounted on the hollow flange plate 67 . The left and right ends of the flange base plate 71 are connected to tie rods 72 , and the other end of the tie rods 72 is connected to a U-shaped opening clamp 73 .

[0060] The beneficial effects of the above technical solution are as follows: when the motor disassembles the bearing, the electric lead screw 62 rotates to drive the adjustment plate 63 to rise above the bearing, and then the telescopic column 66 is tightened to shrink, so that the slide bar 64 slides on the adjustment plate 63. After the U-shaped opening card 73 passes over the bearing, the electric lead screw 62 drives the adjustment plate 63 to descend, so that the U-shaped opening card 73 is nested on the motor shaft, and then the carrying telescopic column 68 is extended to make the working end flexible sleeve contact with the motor shaft, and then the telescopic column 66 is tightened to extend, and the slide bar 64 is pulled to slide on the adjustment plate 63, and the U-shaped opening card 73 pulls the shaft seat off the motor shaft;

[0061] The present invention utilizes an electric lead screw 62 and an adjustment plate 63 to drive the bearing clamp structure 7 to be lifted and lowered. This design can lift and lower motors of any size to different heights, and the bearing clamp structure 7 is connected by a flange base plate 71 and a hollow flange plate 67. U-shaped opening clamps 73 of different specifications can be replaced according to motors of different sizes, thereby ensuring that the bearing removal assembly 6 is adaptable to bearings and shafts of different sizes, thereby improving the versatility of the bearing removal assembly 6.

A lifting platform 84 is installed on the top of the movable slider 81, and a driving motor 4 85 is installed in the center of the lifting platform 84, and a chuck 86 is installed on the working end of the driving motor 4 85.

[0064] The beneficial effects of the above technical solution are as follows: when the rotor is moved out of the motor, the lifting platform 84 adjusts the height of the chuck 86 so that its center is aligned with the motor shaft, the mobile telescopic rod 83 pushes the moving slider 81 forward in the translation slide 82, and the moving slider 81 drives the chuck 86 on the lifting platform 84 to the motor shaft. After the chuck 86 is used to clamp the motor shaft, the mobile telescopic rod 83 pulls the moving slider 81 to reset, and the rotor is pulled out of the motor synchronously. After the rotor is moved out of the motor, the drive motor 4 85 is started to drive the chuck 86 to rotate, which is convenient for maintenance personnel to operate and observe it;

[0065] The present invention utilizes a movable slider 81 and a translation slide 82 to displace the rotor, and is equipped with a chuck 86 to fix the rotor. This design can ensure high-precision and high-stability matching of the rotor and the stator during the separation and installation process, avoiding collision between the rotor and the stator when the rotor is moved out. At the same time, in conjunction with the design of the drive motor 85, the rotor can be observed 360° to avoid rolling and collision when the rotor is placed on a plane for operation.

[0077] The detection module is electrically connected to the data processing module, the control module is electrically connected to the data processing module and the execution module, and the control module controls the execution unit to work based on the data results of the data processing module.

[0078] The control module controls the execution module based on the data result of the data processing module, including the following steps:

[0079] Step 1: Calculate the safety factor S of the motor maintenance platform using the level sensor, displacement sensor 1, displacement sensor 2, angle sensor 1, angle sensor 2, height sensor, fatigue stress sensor 1 and fatigue stress sensor 2 r :

[0080]

[0081] Where: S r is the safety factor of the motor maintenance platform, E is the safety factor weight coefficient of the rotor disassembly component 8, H is the detection value of the level sensor, the unit is mm / m, a is the detection value of the displacement sensor 2, the unit is m, h 1 is the detection value of height sensor 1, in m, H 0 is the initial value of the horizontality of the disassembly platform 13, in mm / m, a 0 is the initial distance of the moving slider 81 in the translation slot 82, in m, h 0 is the motor axis height, in m, β is the detection value of angle sensor 1, α is the detection value of angle sensor 2, Γ is the safety factor weight coefficient of bearing disassembly component 6, σ bi The detection value of fatigue stress sensor 1 on each slide bar 64, in N / m 2 , σ g is the detection value of fatigue stress sensor 2, in N / m 2 , [σ b ] is the allowable fatigue stress of the slide bar 64, in N / m 2 , [σ g ] is the allowable fatigue stress of the reaction plate 65, in N / m 2 ,h 2 is the detection value of height sensor 2, in m, b i is the detection value of the displacement sensor 1 on each slide bar 64, in m;

[0082] Step 2: Data processing module comparison r and S r0 , and calculate the locking parameters of the motor maintenance platform:

[0083] When S r r0 Calculate the locking parameter L of the motor maintenance platform:

[0084]

[0085] Where S r0 is the minimum safety factor of the motor maintenance platform, and L is the locking parameter of the motor maintenance platform;

[0086] Step 3: The control center controls the execution module to perform the locking operation and alarm to display the locking parameters according to the locking parameters. The maintenance personnel compare the calculated locking parameters of the motor maintenance platform with the maintenance locking value table to determine the locking mode and unlocking method of the motor maintenance platform.

[0087] The beneficial effects of the above technical solution are as follows: since the motor is a precision machine, especially between the rotor and the stator, the bearing and the rotating shaft, when the installation accuracy between the two is not up to standard, it will cause the rotor and the stator to collide and the rotating shaft to swing. Similarly, during the disassembly process, higher accuracy is required to ensure the disassembly of the rotor and the bearing. Therefore, the bearing disassembly component 6 and the rotor disassembly component 8 are monitored. When the rotor and the bearing cannot reach the accuracy before disassembly or are about to deviate relatively during the disassembly process (that is, the rotor and the stator deviate and collide, and the bearing and the rotating shaft deviate and get stuck), when the data processing module calculates that the safety factor is lower than the predetermined value, the data processing module calculates the locking parameter according to the safety factor, and the control unit controls the execution module according to the locking parameter to timely lock the motor maintenance platform in accordance with the corresponding locking method and alarm to display the locking parameter, reminding the maintenance personnel to make adjustments;

[0088] The present invention utilizes a control module, a data processing module, a detection module and an early warning module to perform real-time monitoring on a motor maintenance platform, calculates and compares the safety factor of the motor maintenance platform according to current detection data, ensures that the motor rotor and the bearing are not collided or jammed when the motor maintenance platform is inspecting the motor, and ensures the safe operation of the entire system.

[0089] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.​
