DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Embodiment 1, by Figures 1 to 8The present invention comprises a mounting and protecting bracket 1, a transformer body 2 and two electric poles 11, wherein the transformer body 2 is mounted on the top of the mounting and protecting bracket 1, and four movable connecting blocks 3 are rotatably connected at equal distances at both ends of the mounting and protecting bracket 1, and a large vertical block 4 is rotatably connected between one end of the four movable connecting blocks 3 at either end of the mounting and protecting bracket 1, and two horizontal sliding grooves 5 are provided on the opposite sides of the two large vertical blocks 4, and two bidirectional threaded shafts 6 are rotatably connected inside the four horizontal sliding grooves 5, and moving blocks 7 are threadedly connected on both sides of the four bidirectional threaded shafts 6, and an inverted L-shaped fixing plate 8 is fixedly installed on one side of the moving block 7, and the inverted L-shaped fixing plate 8 is fixedly installed on one side of the moving block 7. Arc groove rollers 9 matching electric poles 11 are installed between the inner side of the plate 8 and the upper part of the moving block 7. The two electric poles 11 are respectively located between the four arc groove rollers 9 on one side of the two large vertical blocks 4. A reinforcing member 10 is connected between the surfaces of the two inverted L-shaped fixed plates 8 at the same height on one side of any large vertical block 4. A clamping member 12 is installed between the two arc groove rollers 9 on the same vertical axis on one side of the two large vertical blocks 4. An adjusting cavity 13 is opened in the middle of the two large vertical blocks 4. Motors 14 are installed inside the two adjusting cavities 13. The two motors 14 are respectively connected to the arc groove rollers 9 on the two large vertical blocks 4 for transmission.

[0028] The installation protection bracket 1 includes a first support plate 15 and a second support plate 1501, the opposite ends of the first support plate 15 and the second support plate 1501 are rotatably connected to the movable connection block 3, the middle of the first support plate 15 is provided with adjustment slots 16 at equal distances, the middle of the adjustment slots 16 are fixedly connected with slide bars 17, the surfaces of the slide bars 17 are movably sleeved with sliders 18, the top and bottom of the sliders 18 and the top and bottom of the second support plate 1501 are fixedly installed with fixed strips 19, and the transformer body 2 is installed between the surfaces of the fixed strips 19 at the top of the second support plate 1501, so that it can be stretched horizontally;

[0029] When the two electric poles 11 are slightly tilted, the two electric poles 11 are not parallel. As the installation protection bracket 1 moves upward, the two electric poles 11 will become larger or smaller. Therefore, when the two large vertical blocks 4 move upward, the first support plate 15 and the second support plate 1501 will be driven to move upward through the movable connecting block 3. Since the two electric poles 11 are not parallel, the two large vertical blocks 4 move upward, and the first support plate 15 and the second support plate 1501 will be pulled or pushed to move through the movable connecting block 3. Therefore, the fixed slat 19 can make the slider 18 slide and move on the surface of the slide rod 17, and the installation firmness and stability of the transformer body 2 will not be affected. At the same time, when the electric pole 11 vibrates or shakes, it can also effectively perform horizontal telescopic adjustment to avoid the influence of rigid vibration or shaking on the transformer body 2.

[0030] Embodiment 2, on the basis of embodiment 1, a first rotating shaft 20 is rotatably connected between the moving block 7 and the inverted L-shaped fixed plate 8, the arc groove roller 9 is fixedly installed on the surface of the first rotating shaft 20, one end of the two large vertical blocks 4 is fixedly installed with a fixed cover 21, the two bidirectional threaded shafts 6 on the large vertical blocks 4 are extended to the inside of the fixed cover 21 and are fixedly installed with a first sprocket 22, a first chain 23 is installed between the two first sprockets 22, one end of the bidirectional threaded shaft 6 is extended to the outside of the fixed cover 21 and is fixedly connected with a rotating nut 24, so that effective adjustment can be performed, so that the four arc groove rollers 9 on the large vertical blocks 4 can effectively clamp the electric pole 11;

[0031] When it is necessary to connect the device to the electric pole 11, the four arc groove rollers 9 on the large vertical block 4 are moved so that the electric pole 11 is located between the four arc groove rollers 9 on the large vertical block 4, and then any rotating nut 24 on the large vertical block 4 is rotated by a tool so that the rotating nut 24 drives the bidirectional threaded shaft 6 connected thereto to rotate, and then the two bidirectional threaded shafts 6 on the large vertical block 4 are rotated synchronously through the two first sprockets 22 and the first chain 23. The rotation of the bidirectional threaded shaft 6 will cause the two moving blocks 7 on its surface to move relative to each other, and the relatively moving moving blocks 7 will cause the four arc groove rollers 9 on the large vertical block 4 to clamp the electric pole 11, so that greater friction is generated between the surface of the arc groove roller 9 and the surface of the electric pole 11.

[0032] A transverse through groove 25 is provided between the upper part of the transverse slide groove 5 and the adjusting chamber 13. One end of the first rotating shaft 20 extends to the inside of the adjusting chamber 13 through the transverse through groove 25 and is fixedly connected to the second sprocket 26. A second chain 27 is installed between the two second sprockets 26 on the same vertical line in the adjusting chamber 13. The surfaces of the two first rotating shafts 20 on the upper part of the large vertical block 4 located in the adjusting chamber 13 are fixedly installed with a first worm wheel 28. The upper part of the adjusting chamber 13 is symmetrically rotatably connected to two first worms 29, and the two first worms 29 are respectively meshed with the two first worm wheels 28. The surface of the motor 14 is fixedly connected with a second worm 31; the opposite ends of the two first worms 29 are fixedly connected with a square plug shaft 2901, and the upper part of the adjusting chamber 13 is rotatably connected with an inner square transmission tube 2902, and the two square plug shafts 2901 are respectively movably plugged at the two ends of the inner square transmission tube 2902, and the middle part of the inner square transmission tube 2902 is fixedly installed with a second worm wheel 30, and the second worm 31 is meshedly connected with the second worm wheel 30, so that the circular arc groove roller 9 can be effectively driven to rotate, so that the circular arc groove roller 9 rolls and moves upward on the surface of the electric pole 11;

[0033] By starting the motor 14, the second worm 31 transmits the second worm wheel 30 to drive the inner square transmission tube 2902 to rotate, and the rotation of the inner square transmission tube 2902 will drive the two square plug shafts 2901 to rotate, and the rotation of the two square plug shafts 2901 will drive the two symmetrical first worms 29 to rotate, and the rotation of the two first worms 29 will transmit the two first worm wheels 28 to make the two first worm wheels 28 rotate relative to each other, and the rotation of the two first worm wheels 28 will make the two first rotating shafts 20 located on the same vertical line rotate synchronously in the same direction through the two second sprockets 26 and the second chain 27, and the rotation of the first rotating shaft 20 will drive the circular arc groove roller 9 to rotate, so that the circular arc groove roller 9 rolls and moves upward on the surface of the electric pole 11 and drives the large vertical block 4 to move upward, and the upward movement of the two large vertical blocks 4 will drive the movable connection block 3 to drive the installation protection bracket 1 and the transformer body 2 to move upward and lift.

[0034] The reinforcement members 10 each include two L-shaped plates 36, and the two L-shaped plates 36 are rotatably connected to the inverted L-shaped fixing plate 8. One end of the two L-shaped plates 36 is provided with a through hole, and the two L-shaped plates 36 are connected with threaded pins 37 through the two through holes. The surfaces of the threaded pins 37 are threadedly connected with fixing nuts 38, so as to reinforce the contact between the arc groove roller 9 and the electric pole 11.

[0035] When the arc groove roller 9 contacts the electric pole 11, the two L-shaped plates 36 are adjusted, and the threaded pin 37 is connected between the two L-shaped plates 36 through a perforation, and then the fixing nut 38 is connected to the surface of the threaded pin 37, so that the two L-shaped plates 36 are kept tight; and the tightness of the two L-shaped plates 36 can effectively pull the two inverted L-shaped fixing plates 8 to keep stable, avoiding the compression tension caused by the contact between the arc groove roller 9 and the electric pole 11, which may cause the inverted L-shaped fixing plates 8 to deform, so that the arc groove roller 9 can stably and firmly contact the electric pole 11.

[0036] Embodiment 3, on the basis of embodiment 1, the clamping member 12 includes an internal threaded rotating tube 32, two threaded rods 33 and two right-angled trapezoidal abutment blocks 34, the two right-angled trapezoidal abutment blocks 34 are respectively fixedly connected to one end of the two threaded rods 33, and the two threaded rods 33 are respectively threadedly connected to the two ends of the internal threaded rotating tube 32, and the middle part of the internal threaded rotating tube 32 is provided with jacks 35 at equal distances in an annular shape; the arc groove surface of the arc groove roller 9 is provided with protrusions for increasing friction, the right-angled trapezoidal abutment blocks 34 are clamped between the electric pole 11 and the arc groove roller 9, and the protrusions are not drawn in the drawings;

[0037] The arc groove roller 9 can be effectively clamped and resisted to prevent the arc groove roller 9 from reversing. When the arc groove roller 9 rolls on the surface of the electric pole 11 and moves to a certain height, the clamping piece 12 is placed between the two arc groove rollers 9 located on the same vertical line, and then the internal threaded rotating tube 32 is rotated by rotating the internal threaded rotating tube 32 or inserting a tool into the inside of the socket 35. The rotation of the internal threaded rotating tube 32 will cause the two threaded rods 33 to move out from the inside of the internal threaded rotating tube 32, so that the internal threaded rotating tube 32 drives the right-angled trapezoidal resistance block 34 to resist the arc groove roller 9 between the electric pole 11, thereby effectively preventing the arc groove roller 9 from rotating downward.

[0038] The transformer protection bracket device has a lifting and adjusting function, and the transformer can be installed on the ground, and then the transformer can be lifted to a certain height through its own lifting function. The protection bracket device can be stably and firmly installed between two electric poles, and can be moved stably and safely. At the same time, the protection bracket device can effectively extend horizontally, thereby effectively improving the convenience of transformer installation and playing a role in protecting the transformer. The protection bracket device has a simple structural design, is easy to use and operate, and is stable and reliable. Its performance can meet the use requirements of outdoor transformer installation and protection.

[0039] Furthermore, the transformer protection bracket device is suitable for electric poles with the same lower diameter.
