Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a mounting base for a transformer. Background Art

[0002] The installation of a pole-mounted transformer usually requires the use of a mounting base, which is used to fix the transformer on the pole and provide support. The mounting base helps to maintain the stability and safety of the transformer and keep it at a certain distance from the ground.

[0003] The current installation base usually includes a clamp and a stand composed of channel steel. When installing the transformer, the pole is first erected, and then the clamp is installed at the set position on the pole. After that, the stand is hoisted and placed on the clamp. After the position of the clamp is adjusted until the stand is horizontal, the clamp and the stand are locked, and the subsequent transformer installation can be carried out. However, when adjusting the position of the clamp on this type of installation base, the bolts fixing the clamp need to be loosened, and the clamp is adjusted up and down by manually lifting the clamp. Since there is no reference for workers to judge the adjustment distance during the adjustment process, it takes a long time to adjust the stand to a horizontal level, which easily delays the installation process of the transformer.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model discloses a transformer mounting base, comprising a stand 1 and a clamp mechanism 2 for supporting the stand 1, wherein the clamp mechanism 2 comprises a fixing member 21 for connecting with an electric pole and a movable member 22 for moving on the fixing member 21 to adjust the horizontality of the stand 1;

[0024] The fixing member 21 includes two first hoop plates 211 arranged opposite to each other, and first wing plates 212 are arranged at opposite ends of the two first hoop plates 211, and first bolt assemblies 213 for connecting the two first hoop plates 211 are arranged on the first wing plates 212, and a plurality of first arc-shaped teeth 214 are arranged on the outer peripheral wall of the first hoop plates 211;

[0025] The movable part 22 includes two second hoop plates 221 arranged opposite to each other, the inner diameter of the second hoop plates 221 is not less than the outer diameter of the first hoop plate 211, and the two second hoop plates 221 are each provided with a second wing plate 222 at one opposite end, and the second wing plate 222 is provided with a second bolt assembly 223 for connecting the two second hoop plates 221, and the inner peripheral wall of the second hoop plate 221 is provided with a second arc-shaped tooth 224 meshing with the first arc-shaped tooth 214.

[0026] In the utility model, the first hoop plate 211 is fixed to the pole by the first bolt assembly 213, and then the second hoop plate 221 is installed to the outer side of the first hoop plate 211 by the second bolt assembly 223, and the second arc-shaped tooth 224 is inserted into the first arc-shaped tooth 214. When the stand 1 is placed on the second wing plate 222, the level meter is used to measure whether the stand 1 is installed horizontally. When it is in a non-horizontal state, the second arc-shaped tooth 224 is disengaged from the first arc-shaped tooth 214 by loosening the second bolt assembly 223, and then the movable part 22 can be lifted. The meshing position of the second arc-shaped tooth 224 and the first arc-shaped tooth 214 provides a reference, which is convenient for the installer to determine the height to be adjusted. After adjusting to the allowable horizontal error range, the second bolt assembly 223 can be tightened to fix the position of the movable part 22, thereby completing the rapid adjustment of the horizontal degree of the stand 1.

[0027] In a specific implementation, since the installation height of the transformer and the pole is specified in the installation process of the transformer, the installation position of the clamp mechanism 2 can be marked on the pole before the pole is erected, and then the clamp mechanism 2 can be installed to the corresponding position on the pole after the pole is erected, thereby reducing the distance that the movable part 22 needs to be adjusted during the horizontal adjustment of the stand 1, further improving the installation efficiency.

[0028] In one embodiment, the cross-sections of the first arc-shaped tooth 214 and the second arc-shaped tooth 224 are both right-angled triangles, the inclined surface of the first arc-shaped tooth 214 faces downward, and the inclined surface of the second arc-shaped tooth 224 faces upward. This design can reduce the resistance encountered by the movable part 22 during the upward movement. At the same time, after the movable part 22 is adjusted, the cross-sectional areas of the first arc-shaped tooth 214 and the second arc-shaped tooth 224 are large, so that the fixed part 21 can provide stable support force for the movable part 22.

[0029] In one embodiment, the second bolt assembly 223 is detachably provided with a spring leaf 3 for expanding the distance between the two second hoops 221 under the action of an external force when the movable member 22 is adjusted.

[0030] With such a design, after the second bolt assembly 223 is installed, the spring sheet 3 is used to apply a thrust to the second hoop plate 221, so that the first arc teeth 214 and the second arc teeth 224 of the movable part 22 are meshed when no external force is applied. When pushed by an upward external force, the distance between the two second hoop plates 221 increases under the action of the inclined surfaces of the first arc teeth 214 and the second arc teeth 224, so that the movable part 22 can be pushed upward without loosening the second bolt assembly 223, thereby simplifying the steps for adjusting the height of the movable part 22.

[0031] In a specific implementation, after the height adjustment of the movable member 22 is completed, in order to ensure the stability of the transformer during use, the spring leaf 3 needs to be removed first, and then the second bolt assembly 223 needs to be tightened.

[0032] In one embodiment, at least one arc-shaped clamping block 4 is provided on the top of the second hoop plate 221, and the inner diameter of the arc-shaped clamping block 4 is equal to the inner diameter of the first hoop plate 211. Such a design enables the upper part of the second hoop plate 221 to hold the pole tightly and the lower part to hold the fixing part 21 tightly after the second bolt assembly 223 is tightened, thereby improving the stability of the movable part 22 after installation.

[0033] In one embodiment, a support plate 5 for increasing the placement area of ​​the stand 1 is provided between the arc-shaped clamping block 4 and the second wing plate 222. The support plate 5, the arc-shaped clamping block 4 and the top of the second wing plate 222 are flush. This design increases the stability of the placement of the stand 1 by increasing the contact area between the stand 1 and the clamping mechanism 2.

[0034] In one embodiment, the inner peripheral wall of the arc-shaped clamping block 4 is provided with a rubber pad for increasing the friction resistance between the arc-shaped clamping block 4 and the pole, thereby further improving the stability of the movable part 22 after installation.
