Technical Field
[0001] The utility model belongs to the technical field of positioning structures, and in particular relates to a dry-type transformer installation positioning structure. Background Art
[0002] A dry-type transformer is a special transformer whose core and winding are not immersed in insulating oil. This type of transformer has many advantages, such as no maintenance, long life, safety, environmental protection, and high reliability. Dry-type transformers are often arranged in large quantities in an array in the transformer room. Since the dry-type transformers in the same row are usually closely spaced, it is necessary to pull the dry-type transformers to the aisle for maintenance through slide rails during maintenance. In order to check various parts, it is also necessary to walk around the transformer, which is very inconvenient. Utility Model Content

An auxiliary supporting universal wheel is connected to the bottom of the wheel mounting frame, a rotating shaft is installed on the top of the mounting base, a worm wheel is sleeved on the outer side of the rotating shaft, a worm mounting seat is installed on the top of the mounting base, a worm is rotatably installed on the inner side of the worm mounting seat, a transformer base is installed on the top of the rotating shaft, a transformer body is provided on the top of the transformer base, auxiliary heat dissipation mechanisms are provided on both side surfaces of the transformer base, the auxiliary heat dissipation mechanism includes a fan mounting frame, a fan is installed on the inner side of the fan mounting frame, and an air guide cover is installed on the top of the fan mounting frame.
[0005] The beneficial effects of the utility model are as follows: during daily use, the device can control the operation of the fan to convey the airflow upwards. After the airflow enters the interior of the air guide cover, the airflow can be guided to blow obliquely upwards through the inclined air guide plate, so as to directly cool the outer shell of the transformer main body, effectively take away the heat from the outer surface of the transformer main body, and play a role in improving the heat dissipation performance of the transformer main body; when the transformer main body needs to be inspected and repaired, the locking threaded sleeve can be loosened, and the screw can be rotated by the first hand wheel, and the spiral transmission between the internal threaded sleeve and the screw can drive the sliding crossbeam to slide on the inner side of the slide groove, so that the mounting base can be stably moved to the side under the auxiliary support of the auxiliary supporting universal wheel. The surface slides, and the worm is driven to rotate by turning the second hand wheel, and the transmission between the worm and the worm wheel is used to drive the rotating shaft to rotate, thereby driving the transformer base together with the transformer body to rotate. Due to the self-locking characteristics between the worm and the second hand wheel, the transformer base can be stably stopped at a certain angle.

[0010] As a further improvement of the above technical solution: the worm is meshed with the worm wheel, and one end of the worm is connected to a second hand wheel.
[0011] The beneficial effect of this improvement is: by rotating the second hand wheel, the worm is driven to rotate, and the transmission between the worm and the worm wheel is used to drive the rotating shaft to rotate, thereby driving the transformer base and the transformer body to rotate.
[0012] For ease of operation:
[0013] As a further improvement of the above technical solution: the internal thread sleeve is inserted and connected with the sliding beam, and the screw rod is rotationally connected with the sliding beam.
[0014] The beneficial effect of this improvement is that when the screw rotates, the sliding beam is driven to slide on the inner side of the slide groove through the spiral transmission between the internal threaded sleeve and the screw, so that the mounting base can slide steadily to the side under the auxiliary support of the auxiliary supporting universal wheel. Since the screw and the sliding beam are rotationally connected, the internal threaded sleeve is inserted and connected to the sliding beam and is fixed between the slide groove. Therefore, the screw can move synchronously with the movement of the sliding beam, so that the first hand wheel moves synchronously with the movement of the sliding beam, which is easy to operate.
[0015] To lock the sliding crossbar:
[0016] As a further improvement of the above technical solution: the outer side of the part of the screw located outside the sliding beam is provided with an external thread and is threadedly connected with the locking thread sleeve through the external thread.
[0017] The beneficial effect of this improvement is that after the locking threaded sleeve is tightened, the screw rod is locked by the friction between the locking threaded sleeve and the sliding beam, so that it cannot rotate by itself, thereby locking the sliding beam.
[0018] To blow air on the transformer housing:
[0019] As a further improvement of the above technical solution: an air guide plate is installed inside the air guide cover, and the air guide plate is arranged at an angle.
[0020] The beneficial effect of this improvement is that the fan is running, and the airflow is transported upward. After the airflow enters the air guide cover, the airflow can be guided to blow obliquely upward through the inclined air guide plate, thereby blowing air on the outer shell of the transformer body to achieve a cooling effect.

A rotating shaft 13 is installed on the top of the mounting base 10, and a worm gear 14 is sleeved on the outer side of the rotating shaft 13. A worm mounting seat 15 is installed on the top of the mounting base 10, and a worm 16 is rotatably installed on the inner side of the worm mounting seat 15. A transformer base 18 is installed on the top of the rotating shaft 13, and a transformer body 19 is provided on the top of the transformer base 18. Auxiliary heat dissipation mechanisms are provided on both sides of the transformer base 18, and the auxiliary heat dissipation mechanisms include a fan mounting frame 20, a fan 21 is installed on the inner side of the fan mounting frame 20, and a wind guide cover 22 is installed on the top of the fan mounting frame 20.
[0034] During daily use, the device can control the fan 21 to operate and convey the airflow upward. After the airflow enters the interior of the air guide cover 22, the airflow can be guided to blow obliquely upward through the inclined air guide plate 23, so as to directly cool the outer shell of the transformer body 19, effectively take away the heat from the outer surface of the transformer body 19, and play a role in improving the heat dissipation performance of the transformer body 19; when it is necessary to inspect the transformer body 19, the locking threaded sleeve 9 can be loosened, and the screw 7 can be rotated by the first hand wheel 8, and the sliding crossbeam 5 can be driven to slide on the inner side of the slide groove 4 through the spiral transmission between the internal threaded sleeve 6 and the screw 7, so that the mounting base 10 can slide steadily to the side with the auxiliary support of the auxiliary supporting universal wheel 12. By turning the second hand wheel 17, the worm 16 is driven to rotate, and the transmission between the worm 16 and the worm wheel 14 is used to drive the rotating shaft 13 to rotate, thereby driving the transformer base 18 together with the transformer body 19 to rotate. Since the worm 16 and the second hand wheel 17 have the self-locking characteristics, the transformer base 18 can be stably stopped at a certain angle. The function of driving the transformer base 18 to translate and slide through the first hand wheel 8 and the second hand wheel 17 greatly facilitates the maintenance work of the device and reduces the physical strength required to promote the rotation and movement of the transformer. After completing the maintenance work, the transformer base 18 is moved back to its original position, and the locking threaded sleeve 9 is re-tightened to lock the screw 7 and the mounting base 10.
[0035] One end of the screw rod 7 passes through the sliding beam 5 and is connected to the first hand wheel 8 .
[0036] The threaded spindle 7 is rotated by means of the first hand wheel 8 .
[0037] The worm 16 is meshed with the worm wheel 14 , and one end of the worm 16 is connected to a second hand wheel 17 .
[0038] The worm 16 is driven to rotate by rotating the second hand wheel 17 , and the transmission between the worm 16 and the worm wheel 14 is used to drive the rotating shaft 13 to rotate, thereby driving the transformer base 18 and the transformer body 19 to rotate.
[0039] The internal thread sleeve 6 is inserted and connected with the sliding beam 5 , and the screw rod 7 is rotationally connected with the sliding beam 5 .
[0040] When the screw rod 7 rotates, the sliding beam 5 is driven to slide on the inner side of the slide groove 4 through the spiral transmission between the internal threaded sleeve 6 and the screw rod 7, so that the mounting base 10 can slide steadily to the side with the auxiliary support of the auxiliary supporting universal wheel 12. Since the screw rod 7 and the sliding beam 5 are rotationally connected, the internal threaded sleeve 6 is inserted and connected with the sliding beam 5 and is fixed between the slide groove 4. Therefore, the screw rod 7 can move synchronously with the movement of the sliding beam 5, so that the first hand wheel 8 moves synchronously with the movement of the sliding beam 5, which is convenient for operation.
[0041] The portion of the screw rod 7 located outside the sliding beam 5 is provided with an external thread on the outside and is threadedly connected to the locking thread sleeve 9 through the external thread.
[0042] After the locking threaded sleeve 9 is tightened, the screw rod 7 is locked by the friction force between the locking threaded sleeve 9 and the sliding cross beam 5, so that it cannot rotate by itself, thereby locking the sliding cross beam 5.
[0043] An air guide plate 23 is installed inside the air guide cover 22, and the air guide plate 23 is inclined.
[0044] The fan 21 is running to convey the air flow upward. After the air flow enters the air guide cover 22, the air flow can be guided to blow obliquely upward through the inclined air guide plate 23 to blow air on the shell of the transformer body 19 to achieve a cooling effect.

The spacing is adjusted by sliding the sliding base 2 on the inner side of the bottom positioning guide rail 1. After completing the installation of each group of transformer bodies 19, tighten the locking bolts 24 to fix the sliding base 2 to the bottom positioning guide rail 1. In daily use, the fan 21 can be controlled to run to convey the airflow upward. After the airflow enters the inside of the air guide cover 22, the airflow can be guided to blow obliquely upward through the inclined air guide plate 23, so as to directly cool the outer shell of the transformer body 19, effectively take away the heat from the outer surface of the transformer body 19, and play a role in improving the heat dissipation performance of the transformer body 19. When the transformer body 19 needs to be inspected and repaired, the locking threaded sleeve 9 can be loosened, and the screw 7 can be rotated by the first hand wheel 8 to rotate the screw 7 through the internal threaded sleeve 6 and the screw The spiral transmission between 7 drives the sliding crossbeam 5 to slide on the inner side of the slide groove 4, so that the mounting base 10 slides steadily to the side under the auxiliary support of the auxiliary supporting universal wheel 12, and by turning the second hand wheel 17, the worm 16 is driven to rotate, and the transmission between the worm 16 and the worm wheel 14 is used to drive the rotating shaft 13 to rotate, thereby driving the transformer base 18 together with the transformer body 19 to rotate. Since the worm 16 and the second hand wheel 17 have the self-locking characteristics, the transformer base 18 can be stably stopped at a certain angle. The function of driving the transformer base 18 to translate and slide by the first hand wheel 8 and the second hand wheel 17 greatly facilitates the maintenance work of the device and reduces the physical strength required to promote the rotation and movement of the transformer. After completing the maintenance work, after moving the transformer base 18 back to its original position, re-tighten the locking threaded sleeve 9 to lock the screw 7 and the mounting base 10.
