[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0023] The utility model provides a transformer bushing transportation device, which is equipped with a supporting outer end, a buffering inner retraction spring and a protective buffer plate, so as to solve the problem that in the use of the existing transportation device, when the device is transporting the bushing, the bushing is easy to collide with each other in the device, resulting in the surface of the bushing being broken and causing damage to the material during transportation. Through the combination of the above structures, the use of the transportation device can be achieved. The protective mechanism can be used to isolate the bushing separately during transportation, and the surface of the bushing can be wrapped and buffered to protect it, so as to avoid the bushings from colliding with each other and being broken and damaged. In addition, the buffer plate is rectangular, which is convenient for taking and placing, and can be more in line with the surface size of the bushing to adapt to the relative size.

[0024] The utility model provides a transformer bushing transportation device, which is equipped with a rotating bearing and a bearing connecting frame to solve the problem that the existing transportation device is inconvenient to perform azimuth steering when transporting the bushing during use, and the device needs to be forced to change direction by manpower, which leads to excessive consumption of manpower during transportation and increased human resource consumption. The above structures are combined to achieve that the direction of the transportation device can be adjusted more effectively by using the steering mechanism during use, thereby reducing the consumption of manpower during transportation. Moreover, the bearing and the main body are divided into two parts, so that the direction of the main body can be rotated when the base position is inconvenient. Compared with universal wheels, the utility model has more flexibility and stronger practical effect.

[0025] The utility model provides a transformer bushing transport device, which is equipped with a positioning storage rack, a connecting rod and a positioning limiting column, so as to solve the problem that when the existing transport device is in use, it is inconvenient to limit its direction after the device adjusts its direction, resulting in the problem that the moving direction is easily unrestricted when the device changes its direction. Through the combination of the above structures, the transport device can be used in the process of use. After the driving direction is adjusted, the positioning mechanism can be used to limit the determined driving direction, so as to avoid the situation that the moving direction is unrestricted and the situation that it rotates randomly occurs.
