Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The present invention provides a technical solution: a transportation device that is convenient for fixing dry-type transformers, such as Figure 1 and Figure 2 As shown, a receiving groove 2 is provided around the bottom of the base 1, and a roller fixing plate 3 is slidably connected to the inner wall of the receiving groove 2, and a roller 4 and a first trapezoidal block 5 are fixed at both ends of the roller fixing plate 3, respectively. The height of the receiving groove 2 is greater than the highest height of the roller 4, so that the roller 4 can be retracted into the receiving groove 2 when the transformer does not need to be moved, thereby reducing the pressure on the roller 4 and increasing its service life. A first hydraulic rod 6 is fixed around the inside of the base 1, and a second trapezoidal block 7 is fixed on the first hydraulic rod 6. The outer side of the base 1 A fixing seat 8 is fixed on the top, and a mounting seat 9 is fixed on the outer top of the fixing seat 8. At the same time, a mounting groove 10 is opened above the mounting seat 9. The first trapezoidal block 5 and the second trapezoidal block 7 are snap-connected. The second trapezoidal block 7 is driven by the extension of the first hydraulic rod 6 to press against the first trapezoidal block 5 on the roller fixing plate 3, and the first trapezoidal block 5 and the roller fixing plate 3 are driven to move downward inside the storage groove 2 so that the roller 4 presses against the ground to support the base 1 and the transformer in the upper mounting groove 10, which is convenient for movement and increases its practicality.

[0030] like Figure 1 , Figure 3 and Figure 5As shown, the limiting mechanism 11 for fixing the dry-type transformer is installed at both ends of the interior of the mounting seat 9, and the limiting mechanism 11 includes a movable plate 1101, a connecting rod 1102, a movable rod 1103, a third trapezoidal block 1104, a first spring 1105 and a limiting block 1106. The movable plate 1101 is rotatably connected to both ends of the interior of the mounting seat 9, and the two ends of the movable plate 1101 are rotatably connected to the connecting rod 1102 and the movable rod 1103, respectively, the connecting rod 1102 is connected to the third trapezoidal block 1104, and the third The trapezoidal block 1104 is slidably connected to the bottom of the mounting groove 10, and a first spring 1105 is fixed to the connecting rod 1102. The outer side of the movable rod 1103 is connected to the limit block 1106, and the limit block 1106 is slidably connected to the outer ends of the mounting seat 9. The connecting rod 1102, the movable rod 1103, the third trapezoidal block 1104 and the limit block 1106 constitute a transmission mechanism. The movable plate 1101, the connecting rod 1102, the movable rod 1103, the third trapezoidal block 1104, the first spring 1105 and the limit block There are two groups of blocks 1106, and they are symmetrically arranged. When the transformer is placed on the mounting groove 10 inside the mounting seat 9, the two ends of the bottom of the transformer will press against the third trapezoidal blocks 1104 at the two ends of the bottom of the mounting groove 10, driving the two groups of third trapezoidal blocks 1104 and the connecting rod 1102 to move relative to each other. The relative movement of the connecting rod 1102 simultaneously drives the bottom of the movable plate 1101 at the two ends of the mounting seat 9 to move relative to each other, causing the movable plate 1101 to rotate, thereby causing the top of the movable plate 1101 to move toward each other to cooperate with the movable rod 1103 drives the limit block 1106 to press against the bottom of the transformer, fixing the transformer inside the installation slot 10, which is convenient for installation and fixation. When the transformer is taken out, the transformer is separated from the third trapezoidal block 1104, and then the connecting rod 1102 and the third trapezoidal block 1104 are driven to move toward each other under the elastic force of the first spring 1105 on the outside of the connecting rod 1102. At the same time, the movable plate 1101 rotates to drive the movable rod 1103 and the limit plate 1106 to move relative to each other and separate from the transformer, which is convenient for disassembly and improves work efficiency.

[0031] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the motor 12 is fixed on the outside of the fixing seat 8, and the output end of the motor 12 is connected to the screw rod 13, and the screw rod 13 is rotatably connected to the inside of the fixing seat 8, and the two ends of the screw rod 13 are threadedly connected to the vertical plate 14, and the upper outer wall of the vertical plate 14 is fixed with a first shock-absorbing seat 15. The motor 12, the screw rod 13 and the vertical plate 14 constitute a sliding mechanism, and the sliding distance of the sliding mechanism is the same as the length of the screw rod 13. The motor 12 drives the screw rod 13 to rotate so that the two ends of the screw rod 13 are threadedly connected to the vertical plate 14. 4 move towards each other to clamp the left and right ends of the transformer, thereby improving the fixing effect. The first shock absorbing seat 15 is fixed with a second spring 16 inside, and the first clamping plate 17 is fixed on the outside of the second spring 16. The vertical plate 14 and the first shock absorbing seat 15 are provided with two groups, and they are symmetrically arranged. When the two groups of vertical plates 14 move towards each other, the first clamping plate 17 on the outside of the first shock absorbing seat 15 on the surface is attached to the heat sinks on the left and right ends of the transformer, and the elastic force of the second spring 16 inside the first shock absorbing seat 15 is cooperated to reduce the friction during operation. In order to reduce the impact force on the heat sinks at the left and right ends of the transformer during the transmission process, the protection of the heat sinks is improved. The front and rear ends of the vertical plate 14 are fixed with second hydraulic rods 18, and the second hydraulic rods 18 are rotatably connected to the rotating plate 19. At the same time, the rotating plate 19 is rotatably connected to the front and rear ends of the vertical plate 14. A second shock-absorbing seat 20 is fixed on the vertical plate 14, and a third spring 21 is fixed inside the second shock-absorbing seat 20. At the same time, a second clamping plate 22 is fixed on the outside of the third spring 21. Four groups of rotating plates 19 and second shock-absorbing seats 20 are provided, and they are all symmetrically arranged. When the vertical plate 14 clamps the left and right ends of the transformer, the second hydraulic rods 18 at the front and rear ends of the vertical plate 14 are opened to drive one end of the rotating plate 19 to move outward, and drive the rotating plate 19 to rotate so that the other end of the rotating plate 19 is against the front and rear ends of the transformer, thereby improving the fixing effect, and cooperating with the elastic force of the third spring 21 inside the second shock-absorbing seat 20 on the rotating plate 19 to reduce the impact force on the heat sinks at the front and rear ends of the transformer during transportation, thereby increasing practicality.

[0032] Working principle: When using the transport device for fixing dry-type transformers, first move the transformer to the top of the mounting seat 9 by a forklift so that the bottom of the transformer is in a vertical line with the mounting slot 10, and then place the transformer inside the mounting slot 10. When placing the transformer, the two ends of the bottom of the transformer will press against the third trapezoidal block 1104 inside the mounting slot 10, driving the two groups of third trapezoidal blocks 1104 and the connecting rod 1102 to move relative to each other, and at the same time driving the movable plates 1101 at both ends of the mounting seat 9 to rotate, so that the tops of the movable plates 1101 move toward each other and cooperate with the movable rod 1103 to drive the limit block 1106 to press against the bottom of the transformer, and fix the transformer inside the mounting slot 10, and then turn on the motor 12 outside the fixing seat 8 to drive the screw rod 13 to rotate clockwise. , and at the same time, the vertical plates 14 threadedly connected at both ends thereof are driven to move toward each other so that the first clamping plate 17 on the outer side of the first shock-absorbing seat 15 on the surface of the vertical plate 14 fits the left and right ends of the transformer to fix it, and then the second hydraulic rods 18 at the front and rear ends of the vertical plate 14 are opened to drive the rotating plate 19 to rotate on the outer side of the vertical plate 14 in an inclined state, so that the other end of the rotating plate 19 abuts against the front and rear ends of the transformer, and the second clamping plate 22 on the outer side of the second shock-absorbing seat 20 on its surface clamps the front and rear ends of the transformer, and then the first hydraulic rod 6 inside the base 1 is opened to extend and drive the second trapezoidal block 7 to abut against the first trapezoidal block 5, and drive the first trapezoidal block 5 and the roller fixing plate 3 to move downward inside the storage groove 2 so that the roller 4 abuts against the ground, and the base 1 and the transformer support in the upper mounting groove 10 are supported. The base 1 is then pushed to the loading site by the roller 4. After loading, the first hydraulic rod 6 is depressurized to separate the second trapezoidal block 7 from the first trapezoidal block 5. Under the gravity of the base 1, the roller fixing plate 3 and the roller 4 inside the storage groove 2 are retracted into the storage groove 2, so that the base 1 fits the vehicle surface to increase the friction. During transportation, the second spring 16 inside the first shock-absorbing seat 15 on the surface of the vertical plate 14 cooperates with the elastic force of the third spring 21 inside the second shock-absorbing seat 20 on the rotating plate 19 to reduce the impact force on the heat sinks at the left and right sides and the front and rear ends of the transformer during transportation, thereby improving the protection. When the transportation is completed, the second hydraulic rods 18 at the front and rear ends of the vertical plate 14 are first depressurized to drive the rotating plate 19 to rotate on the outside of the vertical plate 14. The second clamping plate 22 on the outer side of the second shock absorbing seat 20 on the rotating plate 19 is separated from the front and rear ends of the transformer, the motor 12 is turned on to drive the screw rod 13 to rotate counterclockwise, and at the same time, the vertical plate 14 threaded at both ends is driven to move relatively, so that the first clamping plate 17 on the outer side of the first shock absorbing seat 15 on the surface of the vertical plate 14 is separated from the left and right ends of the transformer, and then the transformer is lifted by the vehicle. During the rising process of the transformer, the transformer is separated from the third trapezoidal block 1104, and then the elastic force of the first spring 1105 drives the connecting rod 1102 and the third trapezoidal block 1104 to move toward each other, and at the same time, the movable plate 1101 is rotated to drive the movable rod 1103 and the limit plate 1106 to move relatively and separate and reset from the transformer, which is convenient for subsequent use.
