Description

Technical Field

[0001] This application relates to the field of power engineering technology, and in particular to an auxiliary device and equipment for disassembling and assembling transformer fans. Background Technology

[0002] Converter transformers generate a significant amount of heat during operation, which must be dissipated through a forced oil circulation cooling system. During operation, the heat generated by the core and windings is rapidly transferred to the internal insulating oil, causing its temperature to rise. The oil pump in the forced oil circulation cooling system extracts the hot oil from the transformer and forces it through oil pipes to an external cooler. The cooler is equipped with a fan that continuously blows air onto it, cooling the hot oil. The oil pump then pumps the cooled insulating oil back into the converter transformer. Since the fan is a continuously rotating device, it needs to be replaced periodically due to bearing wear and other factors.

[0003] The converter transformer is equipped with a wind tunnel for installing the wind turbine. The wind tunnel is arranged horizontally along the axis, and some converters need to be installed inside the wind tunnel. The wind turbine can weigh from 50 kg to 106 kg. The installation position of the wind turbine is generally between 2 meters and 8 meters high. During the installation of the wind turbine, lifting equipment or lifting devices are used to lift or raise the wind turbine to the required height. Currently, the replacement device with publication number CN104787693A is often used to assist manpower in fine-tuning the position of the wind turbine, so that the wind turbine is aligned with the front and back of the wind tunnel. Then, manpower is used to push the wind turbine into the wind tunnel. The installation process requires multiple people to work together to push and pull the wind turbine to fine-tune its position and move it. The labor intensity is high and the work efficiency is low.

Detailed Implementation

[0017] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

It should be understood that the terms "first," "second," etc., are used in this application to describe various information, but this information should not be limited to these terms, and these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0019] The transformer fan assembly / disassembly auxiliary device of this application is used to connect to the lifting device 200 to install the fan components into the air duct of the converter transformer; such as Figures 1 to 9 As shown, a preferred embodiment of the auxiliary device for disassembling and assembling transformer fans of this application includes a position adjustment mechanism 1 and a push-pull mechanism 2. One end of the position adjustment mechanism 1 is connected to a lifting device 200, and the push-pull mechanism 2 is connected to the other end of the position adjustment mechanism 1. The fan component is detachably connected to the push-pull mechanism 2. The position adjustment mechanism 1 is configured to adjust the position of the push-pull mechanism 2 in the vertical and horizontal directions so that the fan component is opposite to the wind tunnel in the front-back direction. The push-pull mechanism 2 is configured to push the fan component into the wind tunnel. In use, the lifting device can lift the fan component to the vicinity of the wind tunnel. The position adjustment mechanism 1 is used to precisely adjust the position of the fan component in the vertical and horizontal directions so that the fan component is opposite to the installation position in the wind tunnel. Then, the push-pull mechanism 2 is used to push the fan component into the wind tunnel at low speed. In the wind tunnel, the position of the fan component can be repeatedly and precisely adjusted at low speed in the front-back, left-back, and vertical directions to quickly complete the installation. The auxiliary device for disassembling and assembling transformer fans of this application does not require manual lifting and pushing of the fan component, reducing the labor intensity of fan replacement operations and improving work efficiency.

[0020] Among them, such as Figures 6 to 9As shown, the position adjustment mechanism 1 includes a support member 11, a first sliding member 12, a first driving member 13, a second sliding member 14, and a second driving member 15. The support member 11 is connected to the lifting device 200. The first sliding member 12 is slidably connected to the support member 11. The first driving member 13 connects the first sliding member 12 and the support member 11 to drive the first sliding member 12 to move. The second sliding member 14 is slidably connected to the first sliding member 12. The second driving member 15 connects the second sliding member 14 and the first sliding member 12 to drive the second sliding member 14 to move. The push-pull mechanism 2 is connected to the second sliding member 14. By driving the second sliding member 14 to move up and down through the second driving member 15, the position of the push-pull mechanism 2 in the vertical direction can be adjusted, thereby adjusting the position of the fan component in the vertical direction. By driving the first sliding member 12 to move left and right through the first driving member 13, the position of the push-pull mechanism 2 in the horizontal direction can be adjusted, thereby adjusting the position of the fan component in the horizontal direction.

[0021] Specifically, such as Figures 6 to 8 As shown, the support member 11 is a U-shaped frame formed by four columns. The support member 11 includes a top beam 111 and a bottom beam 112 arranged vertically opposite each other. The lower end of the top beam 111 is provided with a first guide groove extending in the left-right direction, and the upper end of the bottom beam 112 is provided with a second guide groove extending in the left-right direction. The first guide groove and the second guide groove are vertically opposite each other. The upper end of the first sliding member 12 is slidably disposed in the first guide groove, and the lower end of the first sliding member 12 is slidably disposed in the second guide groove. The first sliding member 12 is also a U-shaped frame formed by four pillars. The first sliding member 12 is located in the inner cavity of the support member 11. The first sliding member 12 includes a first pillar 121 and a second pillar 122 arranged relatively apart from each other. The right side of the first pillar 121 is provided with a third guide groove extending in the vertical direction, and the left side of the second pillar 122 is provided with a fourth guide groove extending in the vertical direction. The third guide groove and the fourth guide groove are arranged relatively apart from each other from each other. The left side of the second sliding member 14 is slidably disposed in the third guide groove, and the right side of the second sliding member 14 is slidably disposed in the fourth guide groove. The first driving member 13 and the second driving member 15 are both electric push rods.

[0022] In some embodiments of this application, such as Figure 7As shown, the push-pull mechanism 2 includes a sleeve 21, a spindle 22, and a third drive member 23. The spindle 22 is slidably inserted into the sleeve 21. The third drive member 23 connects the sleeve 21 and the spindle 22 and is configured to drive the spindle 22 and the sleeve 21 to move back and forth relative to each other. One of the spindle 22 and the sleeve 21 is connected to the position adjustment mechanism 1, and the other is configured to connect to the fan component. The third drive member 23 can drive the spindle 22 to retract into the sleeve 21, thereby shortening the push-pull mechanism 2 and enabling the push-pull mechanism 2 to pull the fan component out of the wind tunnel. The third drive member 23 can also drive the spindle 22 to extend out of the sleeve 21, thereby lengthening the push-pull mechanism 2 and enabling the push-pull mechanism 2 to push the fan component into the wind tunnel.

[0023] In some embodiments of this application, the mandrel 22 is connected to the position adjustment mechanism 1, and the sleeve 21 is detachably connected to the fan component. Connecting the mandrel 22 to the position adjustment mechanism 1, with the connector for the fan component located on the outside of the sleeve 21, avoids affecting the retraction of the mandrel 22 into the sleeve 21 if the connector is located on the mandrel 22. In some embodiments of this application, the mandrel 22 is also a tube, and the third drive member 23 is an electric push rod. A portion of the third drive member 23 is located in the cavity of the mandrel 22, and another portion is located in the cavity of the sleeve 21. The third drive member 23 is completely located inside the sleeve 21 and the mandrel 22, with no exposed portion. This results in a smaller outer contour dimension of the push-pull mechanism 2, facilitating the insertion of a portion of the push-pull mechanism 2 along with the fan component into the wind tunnel, and avoiding interference between the push-pull mechanism 2 and the wind tunnel wall when inserted into the wind tunnel.

[0024] In some embodiments of this application, such as Figure 3 As shown, the fan component includes a silencer 101, which has a ventilation hole extending in the front-to-back direction. The silencer 101 includes a hole wall surrounding the ventilation hole. The auxiliary device for disassembling and assembling the transformer fan also includes a first connector 3, which includes a connecting part 31 and a hanging rod part 32. The connecting part 31 is connected to the sleeve 21, and the hanging rod part 32 extends in the front-to-back direction. In the front-to-back direction, one end of the hanging rod part 32 near the position adjustment mechanism 1 is connected to the connecting part 31, the sleeve 21, and... The hanging rods 32 are arranged at intervals above and below each other, forming a hanging space 33 between the hanging rods 32 and the sleeve 21 for inserting the hole wall. In use, the hanging space 33 is first aligned with the hole wall, and then the hole wall is inserted into the hanging space 33 by extending the third drive member 23, thus connecting the push-pull mechanism 2 and the muffler 101. After the muffler 101 is pushed into place, the third drive member 23 is shortened, and the hole wall is removed from the hanging space 33, making it easy to remove the muffler 101 from the push-pull mechanism 2.

[0025] In some embodiments of this application, such as Figure 3As shown, the first connecting member 3 also includes a stop member 34, which is detachably connected to the hanging rod portion 32. The stop member 34 and the connecting portion 31 are arranged at intervals relative to each other, and the hole wall is disposed between the connecting portion 31 and the stop member 34. The stop member 34 can prevent the hole wall from falling out of the hanging space 33, ensuring the reliable connection of the muffler cover 101 on the push-pull mechanism 2.

[0026] In some embodiments of this application, the stop 34 is a fastener. In the front-rear direction, the end of the hanging rod 32 away from the connecting part 31 has a threaded hole, and the fastener is threadedly fitted into the threaded hole. Before placing the hole wall into the holding space 33, the fastener is removed from the connecting part 31. After placing the hole wall into the holding space 33, the fastener is fitted into the threaded hole to stop the hole wall. After the muffler 101 is lifted into place, the fastener is removed again. After the muffler 101 is installed, the third drive member 23 is shortened to disengage the push-pull mechanism 2 from the muffler.

[0027] In some embodiments of this application, such as Figure 5 As shown, the fan component also includes a motor 102, which includes a motor body 1021, an output shaft 1023, and a lifting ring 1022. The lifting ring 1022 is connected to the upper end of the motor body 1021 and is spaced apart from the lifting ring 1022 in the front-rear direction. The auxiliary device for disassembling and assembling the transformer fan also includes a lifting chain 4 and a telescopic rod 5. The upper end of the lifting chain 4 is detachably connected to the sleeve 21, and the lower end of the lifting chain 4 is connected to the lifting ring 1022. The upper end of the telescopic rod 5 is hinged to the sleeve 21, and the lower end of the telescopic rod 5 is connected to the output shaft 1023. When it is necessary to connect the motor 102 to the push-pull mechanism 2, the first connecting piece 3 is removed from the sleeve 21, the lifting chain 4 and the telescopic rod 5 are connected to the sleeve 21, the lower end of the lifting chain 4 is connected to the lifting ring 1022, and the lower end of the telescopic rod 5 is connected to the output shaft 1023. The length of the telescopic rod 5 is adjusted to keep the motor 102 stable, and the motor 102 can be stably lifted. The lower end of the telescopic rod 5 can be connected to the output shaft 1023 in several ways, such as by setting a clamp on the outside of the output shaft 1023 and connecting the clamp to the lower end of the telescopic rod 5 with fasteners. The telescopic rod 5 is a rigid body, which makes it easier to precisely adjust the state of the motor 102 compared to using two hanging chains 4 to connect the motor 102.

[0028] The method for installing a fan using the auxiliary device for disassembling and assembling a transformer fan according to this application is as follows: First, connect the telescopic rod 5 and the lifting chain 4 to the push-pull mechanism 2. Then, connect the motor 102 to the telescopic rod 5 and the lifting chain 4. Next, use the lifting device 200 and the transformer fan disassembly and assembly auxiliary device of this application to move the motor 102 to the vicinity of the wind tunnel. At this time, the motor 102 is roughly aligned with the wind tunnel. Then, use the position adjustment mechanism 1 to fine-tune the position of the motor 102 so that the motor 102 is aligned with the front and back of the wind tunnel. After that, use the push-pull mechanism 2 to push the motor 102 into the wind tunnel. In the wind tunnel, the position of the fan components can be repeatedly adjusted at low speed to quickly complete the installation. Then, remove the lifting chain 4 and the telescopic rod 5 from the motor 102. Then, remove the lifting chain 4 and the telescopic rod 5 from the push-pull mechanism 2. Connect the first connecting piece 3 to the push-pull mechanism 2. Use the lifting device 200 and the transformer fan disassembly and assembly auxiliary device of this application to lift the silencer 101 to the wind tunnel entrance. After repeatedly adjusting at low speed to accurately position the silencer 101, install the fixing screws. The steps for disassembling the fan using the transformer fan disassembly and assembly auxiliary device of this application are as follows: first, use the lifting device 200 and the transformer fan disassembly and assembly auxiliary device of this application to place the soundproof cover 101 into the hanging space 33, then remove the fixing screws and move it away from the wind tunnel opening, and then use the lifting device 200 and the transformer fan disassembly and assembly auxiliary device of this application to move the motor 102 out of the wind tunnel.

[0029] For ease of operation, the auxiliary device for disassembling and assembling the transformer fan in this application includes a controller and a wireless remote controller. The wireless remote controller, the first drive component 13, the second drive component 15 and the third drive component 23 are all connected to the controller via signal. The extension and retraction of the first drive component 13, the second drive component 15 and the third drive component 23 can be controlled by the wireless remote controller to realize remote adjustment of the position of the fan components.

[0030] In summary, the auxiliary device for disassembling and assembling transformer fans of this application includes a position adjustment mechanism 1 and a push-pull mechanism 2. One end of the position adjustment mechanism 1 is connected to the lifting device 200, and the push-pull mechanism 2 is connected to the other end of the position adjustment mechanism 1. The fan component is detachably connected to the push-pull mechanism 2. The position adjustment mechanism 1 can adjust the position of the push-pull mechanism 2 in the vertical and horizontal directions so that the fan component is opposite to the wind tunnel in the front-back direction. The push-pull mechanism 2 can push the fan component into the wind tunnel. In use, the lifting device can raise the fan component to the vicinity of the wind tunnel, and the position adjustment mechanism 1 is used to precisely adjust the position of the fan component in the vertical and horizontal directions so that the fan component is opposite to the wind tunnel. Then, the push-pull mechanism 2 is used to push the fan component into the wind tunnel at low speed. In the wind tunnel, the position of the fan component can be repeatedly and precisely adjusted at low speed to quickly complete the installation of the fan component. The auxiliary device for disassembling and assembling transformer fans in this application eliminates the need for manual lifting and pushing of fan components, reducing the labor intensity of fan replacement operations. It can also adjust the up, down, left, right, forward, and backward directions at low speeds to accurately position and install fan components, thereby improving work efficiency.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] This application also provides an embodiment of transformer fan disassembly and assembly equipment, such as... Figure 1 , Figure 4 As shown, the auxiliary device for disassembling and assembling transformer fans, as described above, also includes a lifting device 200; specifically, any lifting device with a lifting weight ≥ 230 kg and a lifting height ≥ 8 m is applicable. The lifting device 200 includes a lifting arm 201 and a rotation adjustment mechanism 7 connected to the end of the lifting arm 201. The position adjustment mechanism 1 of the auxiliary device for disassembling and assembling transformer fans is connected to the rotation adjustment mechanism 7, and the rotation adjustment mechanism 7 is configured to drive the position adjustment mechanism 1 to swing up and down and left and right.

[0033] Specifically, the auxiliary device for disassembling and assembling transformer fans in this application also includes a connecting seat 6. The position adjustment mechanism 1 is connected to the connecting seat 6. The connecting seat 6 is detachably connected to the rotation adjustment mechanism 7 via hooks and locking pins. The connecting seat 6 can be configured according to the connection structure of different lifting devices. In this embodiment, the lifting device 200 is a spider-type aerial work platform. The rotation adjustment mechanism 7 allows for adjustment of the pitch angle and lateral tilt angle of the fan components, which is beneficial for installing the fan components on uneven ground. The rotation adjustment mechanism 7 includes a swing frame 71, a fourth drive member 72, a rotating frame 73, and a fifth drive member 74. The swing frame 71 is rotatably connected to the lifting arm 201. The fourth drive member 72 is connected to the lifting arm 201 and the swing frame 71 and is configured to drive the swing frame 71 to swing up and down. The rotating frame 73 is rotatably connected to the swing frame 71. The fifth drive member 74 is connected to the rotating frame 73 and the swing frame 71 and is configured to drive the rotating frame 73 to rotate left and right. The position adjustment mechanism 1 is connected to the swing frame 71.

[0034] It should be noted that the lifting arm 201 of the spider-type aerial work platform has left-right and up-down adjustment functions, but its adjustment speed is relatively fast and its adjustment accuracy is relatively low. Therefore, it cannot meet the requirements of low-speed and precise position adjustment of the fan components. In this application, the fan components are first lifted to an adjacent position by the spider-type aerial work platform, and then the position of the fan components is precisely adjusted at low speed by the position adjustment mechanism 1. Finally, the fan components are precisely pushed into the wind tunnel at low speed by the push-pull mechanism 2.

[0035] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
