Description

Technical Field

[0001] This utility model relates to the field of motor maintenance technology, and in particular to a horizontal motor maintenance device. Background Technology

[0002] When overhauling a motor, the main components to be inspected are the rotor and stator. The rotor needs to be disassembled using maintenance equipment.

[0003] The motor maintenance device disclosed in Chinese patent CN218560923U includes a frame, a lifting platform vehicle, a fixing mechanism, and a disassembly mechanism. The fixing mechanism includes an upper arc-shaped plate that can move up and down and a fixed lower arc-shaped plate, which fixes the rotor shaft of the motor to prevent the motor from shaking. The disassembly device includes a hook and a jack, which can push the rotor of the motor out, thereby separating the rotor and stator. It is suitable for motors with tight clamping.

[0004] When using the existing maintenance device, the operator adjusts the height of the lead screw by turning the handwheel, then moves the upper arc plate down to fit the rotating shaft, and then turns the handwheel forcefully to clamp the rotating shaft. However, when clamping a rotating shaft with a small diameter, the operator needs to turn the handwheel many times to clamp the rotating shaft, which results in low work efficiency.

[0005] To address the aforementioned problems, this utility model proposes a horizontal motor maintenance device. Utility Model Content

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This horizontal motor maintenance device consists of a motor, a two-way lead screw, a mounting plate, a guide rod, a bending clamp, a first rotating shaft, a round rod, and a mounting box.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a horizontal motor maintenance device, including a base 1, and a sliding frame 3 is slidably provided on the upper end surface of the base 1.

The upper right end face of the base 1 has cylinders 6 fixedly installed on both the front and rear sides, and the telescopic ends of the cylinders 6 are fixedly connected to the sliding frame 3.

[0026] The sliding frame 3 is equipped with a lifting plate 5 that moves up and down inside.

[0027] A telescopic rod 4 is fixedly installed on the inner bottom surface of the sliding frame 3. The telescopic end of the telescopic rod 4 is fixedly connected to the bottom surface of the lifting plate 5.

[0028] A support plate 7 is fixedly installed on the upper right side of the base 1. A mounting box 8 is fixedly installed on the side wall of the support plate 7. A through hole 10 is opened on the side of the mounting box 8 corresponding to the lifting plate 5. A clamping assembly is provided inside the mounting box 8.

[0029] The clamping assembly includes four connecting plates 17, which are installed in pairs on the upper and lower sides of the inside of the mounting box 8.

[0030] Mounting blocks 18 are fixedly installed on both the upper and lower surfaces of the mounting box 8, corresponding to both sides of the connecting plate 17; the mounting blocks 18 are rotatably connected to the connecting plate 17.

[0031] The end of the connecting plate 17 facing away from the mounting box 8 is rotatably mounted with a bent clamp 13.

[0032] Each bending clamp 13 has a groove at one end near the connecting plate 17, and a second shaft 19 is fixedly installed inside the groove. The second shaft 19 is rotatably connected to the end of the connecting plate 17 away from the mounting box 8.

[0033] A round rod 15 is rotatably mounted on the end of the bending clamp 13 away from the connecting plate 17. Two mounting plates 11 are vertically movable inside the mounting box 8, and a first shaft 14 is rotatably mounted at the bend of each bending clamp 13. Both ends of the first shaft 14 are fixedly connected to the inner wall of the mounting plate 11. A drive assembly for moving the two mounting plates 11 is provided inside the mounting box 8.

[0034] The drive assembly includes a bidirectional lead screw 12, with oppositely oriented threads on its outer surface. The bidirectional lead screw 12 is rotatably mounted inside the mounting box 8. Two mounting plates 11 are threadedly connected to the upper and lower surfaces of the bidirectional lead screw 12, respectively. A motor 9 is fixedly mounted on the lower end face of the mounting box 8, and the output shaft of the motor 9 is fixedly connected to the bidirectional lead screw 12.

[0035] Furthermore, a guide rod 16 is fixedly installed inside the mounting box 8, and the side of the mounting plate 11 facing away from the bidirectional lead screw 12 is slidably connected to the guide rod 16.

[0036] Working principle:

[0037] First, place the horizontal motor on the lifting plate 5 and fix it. Then, start the telescopic rod 4 to control the lifting plate 5 to rise or fall. Adjust the rotor of the horizontal motor by telescopic rod 4 to ensure that the rotor of the horizontal motor to be repaired is on the same axis as the through hole 10 of the mounting box 8, so as to realize the repair work of different models of horizontal motors.

[0038] Start cylinder 6. The output end of cylinder 6 drives the sliding frame 3 to move along the slide groove 2 toward the mounting box 8 until the rotor of the horizontal motor extends into the mounting box 8 through the through hole 10, then cylinder 6 is closed.

[0039] At this time, the motor 9 is started. The output end of the motor 9 drives the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 causes the mounting plate 11, which is threaded to it, to slide along the guide rod 16. When the bidirectional lead screw 12 rotates, it causes the upper and lower mounting plates 11 to move closer to each other. The movement of the mounting plates 11 causes the first shaft 14 to move synchronously, which in turn causes the bending clamping plate 13 to rotate around the axis of the second shaft 19. At the same time, it causes the connecting plate 17 to rotate around the mounting block 18, which in turn causes the round rod 15 to approach the outer arc surface of the rotor that extends into the mounting box 8. This enables the clamping operation of rotors of different diameters. When the round rod 15 abuts against the outer arc surface of the rotor, the motor 9 is turned off. The above actions are completed by the motor 9 to fix the horizontal motor rotor, which greatly improves the clamping and fixing efficiency and reduces the workload of maintenance personnel.

[0040] Start cylinder 6, causing the output end of cylinder 6 to drive the sliding frame 3 to move along the slide groove 2 away from the mounting box 8. At this time, the rotor and stator of the horizontal motor are pulled apart, and the horizontal motor body and rotor can be inspected and repaired.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
