Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a hanging anti-collision dry-type transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Common transformers are generally fixed to the pole through a lower bracket, or placed in a safe and dry location in the working environment through a base. However, in some usage scenarios, it cannot be installed from the bottom and needs to be installed by hoisting. Generally, the installation structure of this type of hanging transformer is slightly complicated, but it has better applicability in various environments.

[0003] According to a disclosed hanging anti-collision dry-type transformer (publication number: CN219105861U), in the above application, the dry-type transformer protection box and the dry-type transformer are installed on a lifting device to be lifted and hung. Compared with the traditional steel cable hanging, it is safer and will not be swayed by strong winds and heavy rains. After the lifting and hanging, the top plate can also block part of the rain in heavy rain.

[0004] However, in actual use of the above equipment, when the dry-type transformer is suspended in the air, all its weight is borne entirely by the L-shaped support frame, and the transformer is generally large in size and weight. The L-shaped support frame is likely to deform during long-term pressure, which affects the stability of the dry-type transformer. At the same time, the deformation of the L-shaped support frame will cause squeezing with the support column, which will make the lifting device unable to adjust the height of the transformer. In view of this, we propose a suspended anti-collision dry-type transformer. Utility Model Content

[0005] The utility model aims to provide a hanging anti-collision dry-type transformer to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a hanging anti-collision dry-type transformer, comprising a workbench, a support column is fixedly installed above the workbench, a lifting assembly is arranged inside the support column, an L-shaped support frame is fixedly installed at the front end of the lifting assembly, a transformer body is fixedly installed on the inner bottom surface of the L-shaped support frame, an auxiliary support assembly is arranged at the bottom of the L-shaped support frame, and the auxiliary support assembly comprises:

[0009] A limit plate, the limit plate is fixedly mounted on the upper surface of the moving plate;

[0010] An anti-skid transverse groove is provided on the front surface of the support column.

[0011] Preferably, the front ends of the limiting rod and the screw rod both pass through the back side of the fixed plate, and the provided limiting rod and the screw rod can limit the movement of the movable plate.

[0012] Preferably, a limit block is fixedly installed at the front end of the screw rod, and the limit block can prevent the screw rod from being separated from the fixing plate, and at the same time, when the limit block rotates, it can drive the screw rod to rotate synchronously.

The deformation space of the rubber plate is limited by the limit plate, thereby reducing the situation that the rubber plate is debonded at the bonding point with the movable plate due to the large friction force.

[0018] 2. The hanging anti-collision dry-type transformer, through the cooperation of the provided grooves, elastic parts and connecting grooves, enables the wedge plate to be inserted into the interior of the anti-slip transverse groove, completely seals the upper end of the rubber plate, and further enhances the limitation of the deformation space of the rubber plate.

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a hanging and anti-collision dry-type transformer, comprising a workbench 1, a support column 2 is fixedly installed above the workbench 1, a lifting component 7 is arranged inside the support column 2, the lifting component 7 comprises: a lifting groove, a threaded rotating rod, a threaded sleeve and a motor, etc., the outer wall of the threaded sleeve fits the inner wall of the lifting groove, and the motor can drive the threaded rotating rod to rotate when the motor is started, thereby driving the threaded sleeve to perform linear motion in the up and down directions under the limit of the inner wall of the lifting groove, and when the threaded sleeve moves, it can synchronously drive the L-shaped support frame 3 to move synchronously, the front end of the lifting component 7 is fixedly installed with an L-shaped support frame 3, and the inner bottom surface of the L-shaped support frame 3 is fixedly installed with a transformer body 4, when the L-shaped support frame 3 moves upward, it can drive the transformer body 4 to move upward for hanging, thereby preventing the transformer body 4 from swinging due to strong wind and heavy rain and colliding with other objects to cause damage, and an auxiliary support component is arranged at the bottom of the L-shaped support frame 3.

[0025] The auxiliary support assembly includes: an oblique support rod 501, a rubber plate 507, a limit plate 508 and an anti-slip groove 509. The oblique support rod 501 is fixedly installed at the bottom end of the L-shaped support frame 3. When the bottom end of the L-shaped support frame 3 moves, the oblique support rod 501 can be driven to move synchronously. A fixed plate 502 is fixedly installed on the back of the oblique support rod 501. A movable plate 503 is arranged on the back of the fixed plate 502. A limit rod 504 is fixedly installed on the left end of the front side surface of the movable plate 503. When the movable plate 503 moves, the limit rod 504 can be driven to move synchronously. A screw 505 is rotatably installed on the right end of the front side surface of the movable plate 503.

[0026] The front ends of the limit rod 504 and the screw 505 are all through the back side of the fixed plate 502. The limit rod 504 can limit the movement of the fixed plate 502. The front end of the screw 505 is fixedly installed with a limit block 506. When the limit block 506 rotates, the screw 505 can be driven to rotate synchronously. When the screw 505 rotates, the movable plate 503 can perform a linear motion in the front and rear directions under the limit of the limit rod 504. The screw 505 is threadedly connected to the fixed plate 502, and the rubber plate 507 is fixedly installed on the back side of the movable plate 503 When the movable plate 503 moves backward, it can drive the rubber plate 507 to move backward synchronously to fit the front surface of the support column 2. The limiting plate 508 is fixedly installed on the upper surface of the movable plate 503, and the anti-slip transverse groove 509 is opened on the front surface of the support column 2. The set limiting plate 508 can limit the deformation of the rubber plate 507 and the deformation amount of the rubber plate 507, thereby reducing the situation where the rubber plate 507 and the movable plate 503 are detached due to excessive friction after the rubber plate 507 is subjected to downward pressure.

[0027] As the rubber plate 507 continues to move backward, it will be squeezed by the movable plate 503 and the support column 2. At this time, the back side of the rubber plate 507 will fill the inside of the anti-slip groove 509, thereby increasing the friction between the rubber plate 507 and the surface of the support column 2. At this time, an incompletely sealed triangular structure is formed between the support column 2 through the cooperation of the set oblique support rod 501, fixed plate 502, movable plate 503, screw 505 and rubber plate 507, and the stability of the L-shaped support frame 3 is enhanced by the friction between the rubber plate 507 and the support column 2.

[0028] A groove 601 is provided on the bottom surface of the limiting plate 508, and an elastic member 602 is fixedly installed on the front side surface of the groove 601, and a wedge plate 603 is provided on the back side of the elastic member 602. The shape of the pointed side of the wedge plate 603 is adapted to the size of the anti-skid transverse groove 509, and a connecting groove 604 is provided on the front side surface of the wedge plate 603. The inner back side of the connecting groove 604 is fixedly connected to the rear end of the elastic member 602. When the limiting plate 508 moves to the back side following the movable plate 503, the wedge plate 603 enters the anti-skid transverse groove 509, thereby limiting the part of the rubber plate 507 entering the anti-skid transverse groove 509, so as to avoid the limiting plate 508 being unable to enter the anti-skid transverse groove 509, resulting in the rubber plate 507 of this part still being deformed upward, resulting in the increase of pressure at the gluing part between the rubber plate 507 and the movable plate 503, resulting in falling off.

[0029] In the present invention, when in use, after the lifting assembly 7 runs through the L-shaped support frame 3 to lift the transformer body 4 to a suitable position, the limit block 506 can be rotated to drive the screw rod 505 to rotate, and then the movable plate 503 is driven to move backward through the limit of the limit rod 504, so that the rubber plate 507 moves backward to fit the support column 2. As the movable plate 503 continues to move, the back side of the rubber plate 507 will fill the inside of the anti-skid horizontal groove 509, increasing the friction between the rubber plate 507 and the support column 2. At this time, the oblique support rod 501, the fixed plate 502, the movable plate 503, the limit rod 504, the screw rod 505 and the movable plate 503 are moved backward. 05. An incompletely enclosed triangular structure is formed between the limit block 506, the rubber plate 507 and the support column 2. The friction force between the rubber plate 507 and the support column 2 is converted into the supporting force of the oblique support rod 501 on the bottom of the L-shaped support frame 3, thereby enhancing the stability of the L-shaped support frame 3, thereby enhancing the stability of the transformer body 4 when it is lifted, and reducing the situation where the L-shaped support frame 3 supports the heavy transformer body 4 for a long time, causing deformation and affecting the stability of the transformer body 4. At the same time, it is avoided that the entire gravity of the transformer body 4 after deformation directly acts on the connection between the threaded sleeve and the threaded rotating rod, causing wear at the connection and affecting the use of the lifting assembly 7.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
