Description

Technical Field

[0001] This utility model relates to the technical field of transformer transfer, and in particular to an on-load tap-changing dry-type transformer transfer device. Background Technology

[0002] In power systems, on-load tap-changing dry-type transformers are a key electrical device that plays a vital role in stabilizing voltage and ensuring the quality of power supply. They are widely used in various substations, industrial plants, and commercial buildings to meet the stringent requirements for voltage stability under different load conditions.

[0003] Because on-load tap-changing dry-type transformers are large in size and heavy in weight, they require frequent transfer operations during their production, installation, maintenance, and replacement. Traditional transfer methods mainly rely on manual handling or the use of simple lifting equipment in conjunction with flatbed trucks for transportation.

[0004] Existing transfer equipment often uses simple rope binding or side blocks for restraint, which cannot adaptively tighten according to the transformer's dimensions. This can easily lead to lateral or longitudinal displacement of the equipment during transfer, making it difficult to guarantee the reliability of the fixation. Existing equipment also struggles to achieve precise angle adjustment. When the transformer needs to be aligned with the installation location, operators must repeatedly adjust the equipment's posture using auxiliary tools, which not only prolongs the operation time but also increases the probability of equipment collisions.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Reference Figures 1-5 This embodiment provides an on-load tap-changing dry-type transformer transfer device, comprising:

[0042] The frame 1 has four casters 11 at the four corners of its bottom, and the frame 1 is supported on the ground by the four casters 11.

[0043] The vehicle plate positioning mechanism 3 is mounted on the vehicle frame 1;

[0044] The frame 1 includes:

[0045] Push handle 12 is fixedly mounted on frame 1;

[0046] Bearing support 13 is fixedly installed at the middle of the top of the frame 1;

[0047] Rotating rod 14 is rotatably mounted on bearing support 13;

[0048] The car plate 15 is fixedly connected to the rotating rod 14. The car plate 15 is fixed by the car plate positioning mechanism 3. Two guide grooves 16 are symmetrically arranged at the top of the car plate 15. Two pressing mechanisms 2 are slidably arranged on each guide groove 16.

[0049] In this embodiment, the operator holds the push handle 12 and pushes the frame 1, using the four casters 11 at the four corners of the bottom of the frame 1 to move the transfer equipment to the vicinity of the on-load tap-changing dry-type transformer. The transformer is placed on the platform 15. Since the platform 15 is rotatably mounted on the bearing support 13 fixed at the top center of the frame 1 via the rotating rod 14, the approximate angle of the platform 15 can be initially adjusted according to the actual situation during placement to facilitate the transformer being placed in a suitable position. Two guide grooves 16 are symmetrically arranged at the top of the platform 15, and two clamping mechanisms 2 are slidably arranged on each guide groove 16. According to the external dimensions of the transformer, the operator slides the four clamping mechanisms 2 to the appropriate positions on the guide grooves 16, so that the clamping mechanisms 2 can approach the transformer from different directions to achieve adaptive clamping and fixing of the transformer, preventing displacement during transfer. When the transformer needs to be aligned with the installation position, the angle of the platform 15 needs to be precisely adjusted. The operator operates the platform positioning mechanism 3. The platform 15 is adjusted; after alignment, the platform 15 is fixed at the current angle position by the platform positioning mechanism 3 to prevent the platform 15 from rotating again during subsequent operations or transportation; after the transformer is fixed and the angle is adjusted, the operator holds the push handle 12 to push the frame 1, and uses the flexibility of the casters 11 to transport the transformer to the designated installation position for subsequent installation work; this transportation equipment has a sliding clamping mechanism 2 on the platform 15 to adaptively clamp the transformer from different directions, effectively preventing the equipment from shifting during transportation, improving the reliability of fixing, and ensuring the safe transportation of the transformer; the platform 15 of this transportation equipment is rotatably mounted on the bearing support 13 by the rotating rod 14 and equipped with the platform positioning mechanism 3, which can flexibly control the rotation and fixing of the platform 15, and can accurately adjust the angle of the platform 15, so that the transformer can be quickly aligned with the installation position, reducing the number of repeated adjustments, shortening the operation time, reducing the risk of equipment collision, and improving installation efficiency.

[0050] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, four roller supports 17 are arranged in a circle on the frame 1, and a support roller 18 is rotatably mounted on each roller support 17. The top of the support roller 18 rolls and fits against the bottom of the vehicle plate 15.

[0051] In this embodiment, four roller supports 17 are arranged circumferentially on the frame 1. The supporting rollers 18 on each roller support 17 roll and fit against the bottom of the vehicle plate 15, providing support force to the vehicle plate 15 from multiple directions. This can evenly distribute the weight of the vehicle plate 15 and the transformer placed on it, preventing the vehicle plate 15 from deforming or tilting due to uneven force, thus enhancing the overall stability of the equipment and ensuring the safety of the transformer during transportation.

[0052] Specifically, such as Figures 3 to 4 As shown, the vehicle platform positioning mechanism 3 includes:

[0053] The hanging plate 31 is fixedly installed on the vehicle frame 1;

[0054] The conduit 32 is fixedly installed on the hanging plate 31;

[0055] The brake lever 33 is slidably inserted into the guide tube 32, and a transmission frame 34 is provided at the bottom of the brake lever 33;

[0056] The base plate 35 is fixedly connected to the transmission frame 34;

[0057] The guide rod 36 is fixedly installed on the hanging plate 31. A spring 37 is sleeved on the guide rod 36. The base plate 35 is slidably sleeved on the guide rod 36. The spring 37 is located below the base plate 35.

[0058] The foot pedal 38 is swung at the bottom of the frame 1, and a pedal 39 is provided on the foot pedal 38. The foot pedal 38 is used to press the bottom plate 35 to slide downward.

[0059] In this embodiment, when the angle of the vehicle platform 15 needs to be adjusted according to the transformer installation position, the operator steps on the foot pedal 39 on the foot pedal 38; the foot pedal 38 swings, and its end presses against the spring force of the spring 37, causing the base plate 35 to slide downward along the guide rod 36; since the base plate 35 is fixedly connected to the transmission frame 34, and the transmission frame 34 is connected to the bottom of the brake lever 33, the base plate 35 slides down, causing the brake lever 33 to slide downward in the guide tube 32, so that the top of the brake lever 33 leaves the vehicle platform 15, releasing the rotation restriction on the vehicle platform 15; the vehicle platform 15 can rotate freely on the bearing support 13 via the rotating rod 14, so that the transformer is accurately aligned with the installation position; after the transformer is aligned with the installation position, the operator releases the foot pedal 39; under the action of the spring force of the spring 37, the base plate 35 slides downward along the guide rod 36. The guide rod 36 slides upward to reset, causing the top of the brake lever 33 to re-contact and press against the vehicle platform 15, thus restricting the rotation of the vehicle platform 15 again and fixing it at the current angle position. This prevents the vehicle platform 15 from rotating again during subsequent operations or transportation, ensuring the stability of the transformer during transportation and installation. The vehicle platform positioning mechanism 3 can flexibly control the contact and separation between the brake lever 33 and the vehicle platform 15, achieving precise adjustment and reliable fixation of the angle of the vehicle platform 15, greatly improving installation efficiency and reducing the risk of equipment collisions. Operators can control the rotation and fixation of the vehicle platform 15 simply by stepping on or releasing the pedal 39, without the need for complex tools or cumbersome operations, saving operating time and labor costs and improving overall work efficiency.

[0060] More specifically, such as Figures 3 to 4 As shown, a wear-resistant plate 3a is provided at the top of the brake lever 33;

[0061] In this embodiment, the wear-resistant pad 3a can effectively withstand the friction between the brake lever and the vehicle plate, reducing wear caused by direct contact between the two, thereby extending the service life of the brake lever and the vehicle plate, and reducing the maintenance cost and replacement frequency of the equipment. The use of the wear-resistant pad 3a can play a role in buffering and shock absorption, reducing direct collision between metals, thereby reducing the noise generated during equipment operation and improving the working environment. Compared with replacing the entire brake lever or vehicle plate, replacing the wear-resistant pad 3a is less costly, simpler to operate, can quickly restore the normal operation of the equipment, reduce equipment downtime, and improve work efficiency.

[0062] Furthermore, the top of the pedal 39 is provided with anti-slip stripes;

[0063] In this embodiment, the anti-slip stripes can effectively increase the friction between the foot and the pedal 39, reduce the possibility of slipping, and prevent the operator from losing balance due to foot slippage, thereby reducing the probability of accidents such as falls and sprains and ensuring the personal safety of the operator. The anti-slip stripes can ensure stable contact between the foot and the pedal 39, allowing the operator to apply force more precisely and avoid uneven force transmission or loss of control due to foot slippage, thereby improving the accuracy and stability of the angle adjustment of the platform 15 and enabling the transformer to be more accurately aligned with the installation position.

[0064] Furthermore, a wear-resistant plate is provided at the top of the base plate 35;

[0065] In this embodiment, the wear-resistant plate can effectively disperse and withstand friction, reduce the wear of the base plate 35 itself, thereby extending the service life of the base plate 35 and reducing the maintenance cost and replacement frequency of the equipment.

[0066] Furthermore, such as Figure 5 As shown, the clamping mechanism 2 includes:

[0067] A clamping support 21 is provided with a guide groove, and a guide strip 22 is provided at the bottom of the clamping support 21. The guide strip 22 is slidably disposed in the corresponding guide groove 16.

[0068] The pressure rod 23 is oscillatingly mounted on the pressure support 21, and a pressure plate 24 is provided at the end of the pressure rod 23;

[0069] In this embodiment, by moving the pressure rod 23 to press the pressure plate 24 against the transformer, the transformer can be self-adaptively pressed from multiple directions, effectively preventing lateral or longitudinal displacement of the transformer during transportation, improving the reliability of the fixation, and ensuring the safety of the transformer during transportation.

[0070] Furthermore, such as Figure 5 As shown, the clamping mechanism 2 also includes:

[0071] The transmission slider 25 is slidably disposed in the guide groove of the clamping support 21, and the transmission slider 25 is provided with an inclined guide surface;

[0072] The transmission wheel 26 is rotatably mounted on the pressure rod 23 and rolls against the inclined guide surface of the transmission slider 25.

[0073] The clamping screw 27 is threadedly inserted into the clamping support 21, and the clamping screw 27 is rotatably connected to the side end of the transmission slider 25.

[0074] In this embodiment, the operator pushes the clamping support 21 according to the external dimensions of the on-load tap-changing dry-type transformer, causing the guide strip 22 at its bottom to slide in the guide groove 16 of the vehicle plate 15, moving the four clamping mechanisms 2 to appropriate positions respectively; after the clamping mechanism 2 is in position, the transformer is clamped; the operator rotates the clamping screw 27, and since the clamping screw 27 is threaded into the clamping support 21, it moves towards the transformer along the thread direction as the clamping screw 27 rotates; because the clamping screw 27 is rotatably connected to the side end of the transmission slider 25, the movement of the clamping screw 27 will drive the transmission slider 25 to slide towards the transformer in the guide groove of the clamping support 21; during the sliding process, the inclined guide surface on the transmission slider 25 will roll relative to the transmission wheel 26 mounted on the pressure rod 23; due to the action of the inclined guide surface, as the transmission slider 25 moves, the transmission wheel 26 will roll along the inclined guide surface, thereby driving the pressure rod 25 to move towards the transformer. The rod 23 rotates around its swing axis on the clamping support 21; the rotation of the rod 23 causes the clamping plate 24 at its end to gradually approach the transformer surface. After the clamping plate 24 contacts the transformer surface, the clamping screw 27 continues to rotate, and the clamping plate 24 applies increasingly larger clamping force to the transformer until the transformer is firmly fixed to the vehicle plate 15; by rotating the clamping screw 27, the transmission slider 25 is driven to move, which in turn drives the rod 23 and the clamping plate 24 to apply clamping force to the transformer. The clamping force can be precisely controlled according to the actual situation of the transformer and the clamping requirements, which improves the accuracy and reliability of clamping; the operation of rotating the clamping screw 27 is simple, and the operator can easily complete the clamping and loosening operations with just ordinary tools; moreover, since the thread drive has the characteristic of saving effort, the operator does not need to apply excessive force when rotating the clamping screw 27 to achieve the clamping of the transformer, which reduces the labor intensity of the operator and improves work efficiency.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
