Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the following embodiments are based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the embodiments.
Examples
As shown in fig. 1-2, the device for accurately measuring the distance between live cables comprises a laser measuring instrument 1 and a fixed bracket 2; the fixed support 2 comprises a fixed platform 21 and four telescopic supporting legs 22; the laser measuring instrument 1 is fixedly arranged at the top of the fixed platform 21; one end of the telescopic supporting leg 22 is rotatably connected to the bottom of the fixed platform 21; the fixed support 2 also comprises an inner reinforcing auxiliary support 23, and the inner reinforcing auxiliary support 23 mainly comprises a central fixed rod 231 and four supporting rods 232; one end of each of the four support rods 232 is rotatably connected to the central fixing rod 231, and the other end of each of the four support rods 232 is rotatably connected to the four telescopic support legs 22.
Furthermore, the other end of the telescopic supporting leg 22 is provided with a detachable running wheel 3, and the running wheel 3 is used for being clamped and fixed on the top of the steel rail 100 and running along the steel rail 100.
Furthermore, the running wheels 3 are made of insulating materials.
When the measurement operation needs to be carried out on the steel rail line, the walking wheels 3 can enable the fixed support 2 to better move on the steel rail 100, and the measurement operation is convenient for an operator. In this embodiment, the running wheels 3 are detachably mounted to the other end of the telescopic support leg 22 by bolts.
In this embodiment, the telescopic support leg 22 is formed by three telescopic rods sleeved with each other.
The working principle of the charged cable distance accurate measuring device is as follows: when the distance measurement of the electrified cable is needed on the steel rail line 100, the four telescopic supporting legs 22 are unfolded, two telescopic supporting legs 22 on one side are erected on the steel rail 100 on one side, and two telescopic supporting legs 22 on the other side are erected on the steel rail 100 on the other side. The laser measuring instrument 1 is adjusted to a horizontal position by adjusting the telescopic lengths of the four telescopic supporting legs 22, and after the laser measuring instrument is adjusted to the position, an operator directly pushes the accurate measuring device for the distance between the electrified threads to move on the steel rail 100 to carry out measurement. When measuring on the roadbed slope foot and the road shoulder, the four telescopic supporting legs 22 are directly placed on the roadbed slope foot or the road shoulder, the laser measuring instrument 1 is adjusted to the horizontal position, and then the measurement can be started.
When the detachable walking wheels 3 are arranged, the walking wheels 3 can be detached and then the fixed support is placed on the slope toe or the shoulder of the roadbed to carry out measurement.
The main principle of utilizing the laser measuring instrument to measure the distance between the charged threads is as follows: as shown in fig. 3-4, the laser measuring instrument automatically calculates the perpendicular distance between the AF line and the PW line by measuring a1 point (AF positive feed line) and then a2 point (PW guard line) using the point-to-point measuring function of the laser measuring instrument. And measuring a3 point and a4 point and a5 point, and automatically calculating the horizontal distance between the AF line and the pillar, namely the distance between the cable and the grounding body by the laser measuring instrument. Then, the crossing distance of the thread can be measured by measuring the points a9 and a10 on the crossed thread, namely, the distance of the charged measuring thread. By using the angle measuring function of the laser measuring instrument, the measuring points a3, a7 and a8 can measure the angle of the rotation angle of the cable. In the figure GW denotes an overhead earth wire.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
