Description

Technical Field

[0001] The utility model relates to the technical field of transformer maintenance, in particular to a cross positioning device for high-voltage bushings. Background Art

[0002] When maintaining a large transformer, the main transformer body needs to be moved on the rails. During the movement, it is necessary to track and position the position of the high-voltage bushing 1 to prevent it from shifting. Currently, the commonly used detection method is to detect the position of the main transformer body, and then calculate whether the position of the high-voltage bushing 1 has shifted. It is impossible to directly and intuitively observe whether the high-voltage bushing 1 has shifted. Summary of the Invention

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a cross positioning device for high-voltage bushings, including an upper cross on the upper end of the high-voltage bushing, a vertical connecting rod is arranged at the end of the upper cross, a lower cross is arranged at the lower end of the connecting rod, and a vertical laser lamp head is arranged at the center of the bottom of the lower cross.

[0005] Preferably, the upper cross is fixedly arranged on the flange at the upper end of the high-voltage bushing, and mounting holes are arranged on the upper cross to cooperate with the flange, and the upper cross is fixed to the upper end of the high-voltage bushing through bolts.

[0006] Preferably, the laser lamp head is connected to the bottom of the lower cross in a magnetic adsorption form.

[0007] Preferably, the connecting rod is a telescopic rod.

[0008] Preferably, nuts are used to limit the upper cross and the lower cross.

[0009] The utility model provides a cross positioning device for high-voltage bushings, which projects the center of the high-voltage bushing to the ground through the laser lamp head, so as to judge whether the center of the high-voltage bushing shifts; the device can directly observe the position of the center bushing, and the device is convenient to disassemble and assemble and easy to store.

[0014] As Figure 2 shown, a cross positioning device for a high-voltage bushing includes an upper cross 2 fixed to the upper end of the high-voltage bushing 1. A vertically downward connecting rod 3 is provided at the end of the upper cross 2. A lower cross 4 is provided at the lower end of the connecting rod 3. A vertically downward laser lamp head 5 is provided at the center of the bottom of the lower cross 4.

[0015] Preferably, the upper cross 2 is fixedly arranged on the flange at the upper end of the high-voltage bushing 1. Mounting holes 6 matching the flange are provided on the upper cross 2, and the upper cross 2 is fixed to the upper end of the high-voltage bushing 1 by bolts.

[0019] When in use, as Figure 3 shown, this device is installed on the high-voltage bushing 1, and then a reference marking 8 is set on the ground. When the light spot of the laser lamp head 5 hits the reference marking 8, the position is normal. If the laser light spot deviates outside the reference marking 8 during the movement of the main transformer box body, the position of the main transformer box body needs to be adjusted.
