Description

Technical Field

[0001] This invention relates to the field of air cooler motor replacement technology, specifically to a converter station air cooler motor replacement device. Background Technology

[0002] During operation, the air cooler in a converter station requires maintenance and replacement of its motor structure. A converter station air cooler motor replacement device, patent application number CN202010762612.X, includes a lifting platform with a clamping mechanism above it for clamping the motor to be replaced, and a rotating mechanism for rotating the clamping mechanism.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please refer to the accompanying drawings. The present invention provides a technical solution: a converter station air cooler motor replacement device, including a base 1, with movable wheels 101 at the four corners of the ground of the base 1, and hydraulic telescopic rods 102 at the four corners of the top surface, and a lifting platform 103 is connected to the four hydraulic telescopic rods 102.

[0031] Side plates 104 are symmetrically fixed on both sides of the top surface of the lifting platform 103. A rotating shaft 202 is rotatably connected between the middle of the two side plates 104. A first support plate 2 and a second support plate 201 are symmetrically fixed on one side of the rotating shaft 202, and the first support plate 2 and the second support plate 201 are perpendicular to each other. Two support platforms 105 are symmetrically fixed on the upper part of the inner side of the side plate 104, and the two support platforms 105 are respectively in contact with the back of the first support plate 2 and the second support plate 201.

[0032] Two arc-shaped support plates are symmetrically fixed between the back sides of the first support plate 2 and the second support plate 201. Multiple teeth are evenly fixed along the circumferential direction on the outer arc surface of the arc-shaped support rod 203. The lifting platform 103 is provided with a slot corresponding to the position of the arc-shaped support rod 203, so that the arc-shaped support rod 203 can pass through the slot and rotate smoothly. Two gear shafts are symmetrically arranged and rotatably connected on both sides of the bottom surface of the lifting platform 103. One end of the gear shaft is connected to a motor. The two gear shafts are parallel to the rotating shaft 202, and two drive gears 106 are symmetrically fixed on each gear shaft. The two drive gears 106 located on the same side are located on the bottom sides of the arc-shaped support rod 203 and mesh with the teeth on the arc-shaped support rod 203.

[0033] When it is necessary to move the air cooler motor onto the first support plate 2, the arc-shaped support rod 203 is rotated by the drive gear 106, so that the first support plate 2 is in a vertical state and the second support plate 201 is in a horizontal state. Then, the air cooler motor is lowered onto the second support plate 201 by external auxiliary devices, and the air cooler motor is pushed inward and makes contact with the first support plate 2. Then, the arc-shaped support rod 203 drives the first support plate 2, the second support plate 201 and the air cooler motor to rotate by the motor and the drive gear 106, so that the first support plate 2 rotates to a horizontal position, thereby flipping the air cooler motor to a horizontal position. The air cooler motor can then be pushed outward and corresponding maintenance and replacement operations can be performed on the air cooler motor.

[0034] When the first support plate 2 and the second support plate 201 rotate, the arc-shaped support rod 203 and the four drive gears 106 at the bottom provide support, improving the positional stability of the first support plate 2 and the second support plate 201, reducing the influence of gravity and other factors on the rotating shaft 202, improving the overall structural reliability of the device, and when the first support plate 2 or the second support plate 201 is horizontal, the support platform 105 on the corresponding side provides support for the first support plate 2 and the second support plate 201, improving the positional stability of the air cooler motor when it is placed on the second support plate 201 or when it is maintained on the first support plate 2.

[0035] Example 2

[0036] The structure of this embodiment is basically the same as that of Embodiment 1, except that the bottom end of the first support plate 2 extends downward and a vertical first slide groove 205 is provided in the middle. A vertical working plate 4 is slidably connected in the first slide groove 205, and a movable seat 401 is fixed on the side of the working plate 4 away from the second support plate 201. Two vertical screws 402 are symmetrically arranged and threadedly connected in the movable seat 401. The screws 402 are rotatably connected to the first support plate 2 and one end is connected to a motor. When the air cooler motor is located on the second support plate 201, the working plate 4 on the first support plate 2 is located at the inner end of the second support plate 201, so that the air cooler motor moves inward along the first support plate 2. As the first support plate 2 and the working plate 4 rotate to the horizontal, the air cooler motor can be located in the middle of the workbench, and the working plate 4 drives the air cooler motor to move outward through the screws 402 and the movable seat 401, which facilitates maintenance personnel to repair and replace it.

[0037] Among them, one end of each of the two screws 402 is fixed with a first gear 403, and the two first gears 403 mesh with a second gear 404. The second gear 404 is connected to a motor. Through the drive of the motor and the transmission of the first gear 403 and the second gear 404, the two rotate simultaneously, so that the moving seat 401 drives the working plate 4 to move.

[0038] The first slide 205 has symmetrically fixed support slide plates 206 on both sides in the vertical direction, and the working plate 4 has plate grooves on both sides, which are slidably connected to the support plate through the plate grooves. When the first support plate 2 rotates to the horizontal, the two sides of the working plate 4 are located on the support slide plates 206. The support slide plates 206 provide support and limit the working plate 4, reducing the influence of the weight of the working plate 4 and the motor on it on the screw 402.

[0039] Example 3

[0040] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the second support plate 201 is provided with a second sliding groove 204 in the middle, and a sliding seat 301 is provided in the second sliding groove 204. The sliding seat 301 is provided with grooves 305 symmetrically in the middle of both ends, and the two sides of the second sliding groove 204 are slidably connected to the grooves 305 respectively. The upper part of the sliding seat 301 is connected to a placement plate 3 by a plurality of springs evenly arranged. A plurality of spring rods 303 are evenly fixed on the bottom surface of the placement plate 3. The bottom end of the spring rod 303 passes through the sliding seat 301 and is fixed with a spring plate 304.

[0041] When the air cooler motor is moved onto the first support plate 2, the motor falls onto the placement plate 3, and the springs and other structures at the bottom act as a buffer to prevent the motor from falling onto the second support plate 201 and causing an impact. Then, by pushing the sliding seat 301, the placement plate 3 moves the motor closer to the first support plate 2, which facilitates the subsequent flipping of the motor.

[0042] The sliding seat 301 has multiple balls evenly distributed on the top and bottom surfaces of the groove 305. The balls contact the top and bottom surfaces of the second support plate 201 respectively. The balls reduce the friction of the sliding seat 301 relative to the second support plate 201 during sliding, so that the air cooler motor on the placement plate 3 can move quickly to the first support plate 2.

[0043] Magnet blocks 302 are fixed to the outer ends of the sliding seat 301 and the second sliding groove 204 respectively. When the sliding seat 301 moves the placement plate 3 to the outer end of the second sliding groove 204, the two magnet blocks 302 come into contact with each other and attract and fix each other, so as to prevent the placement plate 3 and the sliding seat 301 from moving randomly during the process of transporting the air cooler motor.
