[0025] Reference Figure 1-6 , a convenient-to-operate power plant motor maintenance equipment, comprising a fixed base 1, a lifting assembly is fixedly installed on the upper end surface of the fixed base 1, support plate grooves 101 are opened on the left and right sides of the fixed base 1, and support plate assemblies are arranged inside the two groups of support plate grooves 101. By moving the fixed base 1, the motor to be repaired is located at the center of the fixed base 1, and then the motor can be lifted by the lifting assembly;

[0026] The support plate assembly includes a first support plate 5 and a second support plate 6 that are rotatably connected. The two groups of first support plates 5 are arranged between the two groups of second support plates 6. The interior of the support plate groove 101 is fixedly connected with a fixed block 103. The outer end of the second support plate 6 is rotatably connected with a first rotating rod 7. The rear end of the first rotating rod 7 is rotatably connected to the fixed block 103. The inner end of the first support plate 5 is rotatably connected with a second rotating rod 8. An opening and closing assembly for driving the second rotating rod 8 to move is provided on the rear side of the fixed base 1. The second support plate 6 and the first support plate 5 are rotated and unfolded. In this way, the two groups of first support plates 5 and second support plates 6 cooperate to form a support plate assembly that supports the motor, which facilitates the maintenance of the motor. The device does not require a counterweight block for support and can stably lift the motor. At the same time, the motor does not need to rotate. In this way, the device will not flip over and has good stability.

[0027] The opening and closing assembly includes a locking plate 104 fixed inside the fixed base 1, and a moving groove 105 is opened at the bottom of the locking plate 104. Two groups of sliding blocks 9 are slidably connected inside the moving groove 105. The rear ends of the two groups of second rotating rods 8 are respectively connected to the two groups of sliding blocks 9 for rotation. Through the cooperation of the locking plate 104 and the moving groove 105, the movement of the sliding block 9 can be restricted without rotation. Through the movement of the sliding block 9, the second support plate 6 can be driven to unfold with the cooperation of the rotation of the second rotating rod 8.

[0028] The movable groove 105 is internally rotatably connected with a bidirectional screw rod 10 that passes through the sliding block 9. The two groups of sliding blocks 9 are respectively sleeved on the threads at both ends of the bidirectional screw rod 10. The rotation of the bidirectional screw rod 10 can drive the two groups of symmetrical sliding blocks 9 to move inward or outward at the same time.

[0029] A second motor 11 is fixedly mounted on the outer end surface of the fixed base 1 , and the output shaft of the second motor 11 is transmission-connected to the bidirectional screw rod 10 , so that the bidirectional screw rod 10 can be driven to rotate by the second motor 11 .

[0030] The lifting assembly includes two groups of lifting slides 2, which are fixedly connected to the left and right sides of the upper end surface of the fixed base 1 by bolts. The lifting slides 2 are internally slidably connected to the lifting plate 3, and the lifting slides 2 are internally rotatably connected to the lead screw 4 that penetrates the lifting plate 3. The upper end surface of the lifting slide 2 is fixedly installed with a first motor 401, and the output shaft of the first motor 401 is transmission-connected to the lead screw 4. The lead screw 4 is driven to rotate by the first motor 401, which can drive the lifting plate 3 to move, thereby lifting the motor.

[0031] A mounting plate 301 is fixedly connected to the middle of the lifting plate 3, and a lifting device is fixedly installed on the lower end surface of the lifting plate 3. The installation of the lifting device is facilitated by providing the mounting plate 301, and the lifting device can be replaced by a clamping device.

[0032] The front side of the fixed base 1 is movably engaged with a locking piece 12, which fixes the first support plate 5 and the second support plate 6 so that they cannot be flipped over. A fixing plate 102 is provided inside the fixed base 1, and the upper end surface of the fixing plate 102 movably abuts against the lower end surfaces of the first support plate 5 and the second support plate 6. The locking piece 12 is inserted into the front side of the fixed base 1. At this time, the locking piece 12 fixes the first support plate 5 and the second support plate 6 so that they cannot rotate, thereby improving the supporting strength of the support plate assembly. At the same time, the supporting strength of the support plate assembly is further improved by providing the fixing plate 102.

[0033] A plurality of sets of parts slots 106 are provided on the rear side of the fixed base 1. By providing the parts slots 106, the disassembled motor parts can be placed in the parts slots 106 for convenient storage and to prevent the parts from being lost.

[0034] Working method: When working, the fixed base 1 is moved so that the motor to be repaired is located at the center of the fixed base 1, and then the first motor 401 drives the screw rod 4 to rotate, which can drive the lifting plate 3 to move, thereby lifting the motor. At this time, the second motor 11 drives the bidirectional screw rod 10 to rotate, driving the two sets of sliding blocks 9 to move inward at the same time. In this way, under the movement of the second rotating rod 8, the second support plate 6 and the first support plate 5 can be driven to rotate and unfold. The two sets of first support plates 5 and second support plates 6 cooperate to form a support plate assembly supporting the motor. Finally, the engaging piece is inserted into the front side of the fixed base 1. At this time, the engaging piece fixes the first support plate 5 and the second support plate 6 so that they cannot rotate, thereby improving the supporting strength of the support plate assembly. When the motor is placed on the support plate assembly, the fixed plate 102 can further improve the supporting strength of the support plate assembly, which is convenient for the maintenance of the motor. The device does not require the support of a counterweight block, can stably lift the motor, and does not need to rotate the motor. In this way, the device will not tip over and has good stability.
