Technical Field

[0001] The utility model belongs to the technical field of power accessories, and in particular relates to a positioning and mounting frame for a power high-voltage bushing. Background Art

[0002] The power high-voltage bushing is an important device used in power systems, mainly for insulation and support. It is usually installed in partitions such as walls or boxes for one or several conductors to pass through, ensuring reliable insulation performance between the high-voltage conductor and the partition with different potential.

[0003] In the past, when installing the high-voltage bushing, it was necessary to open an installation square groove in the wall in advance. The square groove was a blind hole, and then a circular through hole was opened in the middle of the square groove for one end of the high-voltage bushing to pass through. However, when the staff installed the high-voltage bushing, they could not quickly position the bushing, and the installation efficiency was slow. In addition, the bushing was prone to collision and friction with the inner wall of the groove during installation, and the safety of the bushing could not be guaranteed. Utility Model Content

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

[0022] Embodiment 1:

[0023] See also Figure 1-Figure 3 As shown, a positioning and mounting frame for a high-voltage electric bushing includes:

[0024] A fixing frame 11, a threaded column 12 is disposed at the bottom end of the fixing frame 11, a sleeve column 13 is threadedly connected to the outer wall of the threaded column 12, and a toothed plate 14 is fixedly connected to the top end of the sleeve column 13;

[0025] The adjusting mechanism 2 includes a rotating rod 21, a built-in groove 22, a groove column 23, a positive and negative threaded rod 24 and a movable plate 25. The adjusting mechanism 2 is arranged on the surface of the fixed frame 11. The rotating rod 21 is movably connected to the surface of the fixed frame 11, and one end of the rotating rod 21 is inserted into the inner side of the fixed frame 11. The built-in groove 22 is opened on the inner side of the fixed frame 11. The groove column 23 is slidably connected to the inner side of the built-in groove 22. The positive and negative threaded rod 24 is movably connected to the inner side of the built-in groove 22. The movable plate 25 is fixedly connected to one end of the groove column 23 away from the positive and negative threaded rod 24;

[0026] The offset mechanism 3 includes a hollow groove 31, a sliding rod 32, a sleeve block 33, an abutting spring 34, a spring column 35 and a circular ring plate 36. The hollow groove 31 is opened on the surface of the fixed frame 11, the sliding rod 32 is fixedly connected to the inner side of the hollow groove 31, the sleeve block 33 is sleeved and connected to the outer surface of the sliding rod 32, the abutting spring 34 is connected to the surface of the sleeve block 33, the spring column 35 is fixedly connected to the outer wall of the sleeve block 33, and the circular ring plate 36 is connected to the end of the spring column 35 away from the sleeve block 33.

[0027] Depend on Figure 1 and Figure 2It can be seen that the outer wall of the rotating rod 21 is fixedly connected with the first conical teeth, the outer wall of the forward and reverse threaded rod 24 is fixedly connected with the second conical teeth, and the first conical teeth are meshed with the second conical teeth, the built-in grooves 22 are symmetrically opened on the inner side of the fixed frame 11 in two groups, the groove columns 23 are symmetrically threadedly connected to the two ends of the forward and reverse threaded rod 24 in two groups, the rotating rod 21 is symmetrically movably connected to the surface of the fixed frame 11 in two groups, and the surface of the movable plate 25 is fitted with an anti-slip pad 26, and the anti-slip pad 26 is fixedly connected to the surface of the movable plate 25 by bolts.

[0028] As can be seen from the above, first the staff places the fixed frame 11 on the inner side of the square groove pre-opened on the wall surface, and by rotating the sleeve column 13 and holding the tooth plate 14, the tooth plate 14 is prevented from rotating, and then the position height of the two sets of tooth plates 14 is adjusted. When the tooth plate 14 is in contact with the inner wall of the square groove, the two sets of rotating rods 21 are rotated at the same time, so that the first conical teeth drive the second conical teeth to rotate, and then drive the positive and negative threaded rods 24 to rotate, and the two halves of the positive and negative threaded rods 24 are provided with positive and negative threads, so that the two sets of groove columns 23 are displaced in opposite directions, thereby driving the movable plate 25 to move, and the anti-slip pad 26 is in contact with the groove wall, so that the fixed frame 11 can be fixed.

[0029] For details, refer to Figure Figure 2 As shown, the slot column 23 is slidably connected to the inner side of the built-in slot 22, the outer wall of the slot column 23 is provided with a slide groove, and the inner wall of the built-in slot 22 is provided with a slider, so that the slider slides on the inner side of the slide groove, and then when the forward and reverse threaded rods 24 rotate, the slot column 23 does not rotate.

[0030] Embodiment 2:

[0031] refer to Figure 2-Figure 3 As shown, the inner side of the circular plate 36 is threadedly connected with an adjusting screw 37, and the end of the adjusting screw 37 away from the inner wall of the circular plate 36 is movably connected to an arc plate 38 through a rotating shaft, and a movable ball 39 is provided on the inner side of the arc plate 38. The adjusting screw 37 is threadedly connected to the inner side of the circular plate 36 in two groups, and the arc plate 38 and the inner wall of the circular plate 36 are connected by a telescopic rod.

[0032] By rotating the adjusting screw 37, the position of the arc plate 38 can be adjusted, so that the arc-shaped arc plate 38 can be fitted on the surface of the pipe sleeve of different sizes to assist the movement of the sleeve. The movable ball 39 is arranged on the inner side of the arc plate 38, and part of the surface of the movable ball 39 leaks out of the surface of the arc plate 38. The movable ball 39 can roll to assist the movement of the sleeve.

[0033] The outer surface of the slide rod 32 is fitted into the sleeve block 33, and the outer surface of the sleeve block 33 is connected to the abutment spring 34. One end of the abutment spring 34 is connected to the surface of the sleeve block 33, and the other end of the abutment spring 34 is connected to the inner wall of the hollow groove 31, so that the position movement of the sleeve block 33 is limited by the abutment spring 34. The sleeve block 33 can undergo a certain degree of displacement movement, but it needs to be subjected to a large force. Similarly, the spring column 35 can undergo telescopic movement, which makes it convenient for the staff to adjust the position of the circular plate 36, thereby facilitating the penetration of the pipe sleeve.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
