DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0025] Reference Figure 1-5 The utility model discloses a pole-mounted circuit breaker mounting bracket, comprising a mounting bracket 1 for mounting a pole-mounted circuit breaker and a PT. The mounting bracket 1 comprises a first parallel beam 101 and a second parallel beam 104. The first beam 101 and the second beam 104 have the same specifications. A first longitudinal beam 102 is welded between the first beam 101 and the second beam 104. A plurality of first longitudinal beams 102 are evenly distributed at both ends of the first beam 101 and the second beam 104. Figure 1 As shown, four first longitudinal beams 102 , two in a group, are distributed between the first transverse beam 101 and the second transverse beam 104 to form a rectangular frame structure.

[0026] The first crossbeam 101, the first longitudinal beam 102, and the second crossbeam 104 are all provided with mounting holes 107. When in use, the two switch bodies are mounted between the first crossbeam 101 and the second crossbeam 104, and the two PTs are mounted on the first longitudinal beam 102 on both sides respectively.

[0027] A clamp 2 is provided on the side of the second crossbeam 104 away from the first crossbeam 101. The clamp 2 and the first crossbeam 101 and the second crossbeam 104 are detachably hinged together through the support frame 3. After the production is completed in the factory, the support frame 3 is disassembled and folded together with the mounting frame 1 and the clamp 2 to save storage space. The support frame 3 is assembled during installation.

[0028] The clamp 2 includes a first clamp 201 flush with the second crossbeam 104 and a second clamp 202 located below the first clamp 201. The first clamp 201 and the second crossbeam 104 are hinged by a third longitudinal beam 304, and the second clamp 202 and the first crossbeam 101 are hinged by an oblique beam 301. When in use, the first clamp 201 and the second clamp 202 are respectively put on the same electric pole, and the second clamp 202 supports the switch body and PT from below through the oblique beam 301.

[0029] One end of the third longitudinal beam 304 is fixedly connected to the first clamp 201, and the other end is connected to the first hinged seat 105. One end of the first hinged seat 105 is rotatably connected to the second cross beam 104, and the other end is hinged to the third longitudinal beam 304. Specifically, the third longitudinal beam 304 and the second cross beam 104 are hinged through the first hinged seat 105. The first hinged seat 105 is close to one end of the third longitudinal beam 304 and is hinged to the third longitudinal beam 304, so that the third longitudinal beam 304 can rotate up and down. The first hinged seat 105 is close to one end of the second cross beam 104 and is rotatably connected to the second cross beam 104, so that the first hinged seat 105 can rotate up and down around the axis of the second cross beam 104.

[0030] A second longitudinal beam 302 is connected between the second clamp 202 and the oblique beam 301. One end of the second longitudinal beam 302 is fixedly connected to the second clamp 202, and the other end is hinged to the oblique beam 301. The other end of the oblique beam 301 is hinged to the bottom of the first cross beam 101, so that the oblique beam 301 can rotate up and down, and at the same time, the second longitudinal beam 302 can also rotate up and down.

[0031] In the present application, the first clamp 201 is composed of a first fixed part 203 and a movable part 205, and the second clamp 202 is composed of a second fixed part 204 and another movable part 205. The first fixed part 203, the second fixed part 204 and the movable part 205 are all semicircular ring structures. The two ends of the first fixed part 203 and the second fixed part 204 are respectively fixedly connected to the fourth cross beam 305, and the other end of the fourth cross beam 305 is fixedly connected to the third longitudinal beam 304 or the second longitudinal beam 302.

[0032] Both ends of the movable part 205 are fixedly connected to the third crossbeam 206, and the third crossbeam 206 is aligned with the fourth crossbeam 305. Through holes are processed on the third crossbeam 206 and the fourth crossbeam 305 for passing bolts to fasten the first fixed part 203 and the movable part 205, and the second fixed part 204 and the movable part 205 together.

[0033] The bottom of the first hinge seat 105 is connected to a vertical beam 303, which is located directly below the second cross beam 104. One end of the vertical beam 303 is fixedly connected to the first hinge seat 105, and the other end is detachably hinged to the second longitudinal beam 302.

[0034] Specifically, the vertical beam 303 and the second longitudinal beam 302 are connected together through the second hinge seat 307. The second hinge seat 307 includes an angle plate 308 fixed on the second longitudinal beam 302. The two angle plates 308 are respectively located on both sides of the vertical beam 303. The angle plates 308 are rotatably provided with a hinge bolt 106. The hinge bolt 106 passes through the bottom end of the vertical beam 303. When disassembling, the hinge bolt 106 is pressed, thereby separating the vertical beam 303 from the second longitudinal beam 302.

[0035] In the present application, there are two oblique beams 301 , which are parallel to each other. There are also two second longitudinal beams 302 , which are hinged to the two oblique beams 301 respectively. A fifth cross beam 306 is fixedly connected between the two second longitudinal beams 302 to enhance the stability between the two second longitudinal beams 302 .

[0036] An extension beam 103 for installing a lightning arrester is fixedly connected to the outer side of the first longitudinal beam 102 . There are six extension beams 103 , three in a group, which are respectively welded to the outer side of the outer first longitudinal beam 102 .

[0037] Working principle: During storage and transportation, the bracket remains in a folded state. Specifically, the hinge bolt 106 on the second hinge seat 307 is removed, and then the third longitudinal beam 304 and the first fixing part 203 are rotated upward and forward to above the first cross beam 101 and the second cross beam 104. At this time, the vertical beam 303 is rotated upward to the original position of the third longitudinal beam 304, or the vertical beam 303 is directly rotated to the bottom of the third longitudinal beam 304, and then the second fixing part 204 is pulled to make the oblique beam 301 and the second longitudinal beam 302 extend forward and fit with the bottom of the first cross beam 101 and the second cross beam 104, so that multiple brackets can be folded in this way and stacked together to save storage space.

[0038] When installation is required, rotate the third longitudinal beam 304 and the oblique beam 301 downward so that the third longitudinal beam 304 and the second longitudinal beam 302 are docked together, and connected together using the hinge bolts 106. Then use a crane to fix the bracket on the utility pole through the first clamp 201 and the second clamp 202. Finally, use a crane to install the switch body, PT and lightning arrester on the mounting frame 1.
