Description

Quick measuring device for pole and tower cable angle

technical field

The utility model relates to an angle measuring device, in particular to a quick measuring device for the angle of a pole and tower stay wire.

Background technique

The power line guy wire is used to balance the lateral load and wire tension acting on the tower, so as to ensure that the tower does not tilt and collapse, and can effectively reduce the consumption of tower materials and reduce the cost of the line. Whether the angle of the guy wire to the ground meets the design requirements is very important for the force of the pole and the safe and stable operation of the transmission line. At present, the measurement methods for the angle of the cable mainly include the measurement method of the digital display rangefinder, the measurement method of the tape measure and the measurement method of the theodolite.

However, the above mainstream methods all have certain limitations. Measurement method of the digital display rangefinder: the digital display rangefinder has a large measurement distance error in the short-distance measurement range. When calculating the inverse trigonometric function, it is necessary to comprehensively consider the height of the person and the height of the handheld digital display rangefinder. The calculation is relatively cumbersome and time-consuming. Tape measurement method: It is difficult to measure the complex terrain, human measurement error is large, and at least two people are required to work, and one person to climb the pole to obtain the data, and then use the inverse trigonometric function to calculate the angle of the cable, which is relatively cumbersome and consumes manpower and effort. Time; if the guide pull (the pull wire that is closer to the wire) is measured, power outage work is required if the safety distance is not met. Theodolite measurement method: the weight of theodolite is about 6.5 kg, and it is inconvenient to carry to the construction and maintenance site; the operation steps of theodolite are relatively cumbersome, such as centering, leveling, aiming at the target, adjusting the focal length, fixing the aiming part, aiming point, etc., and handling And the operation is relatively time-consuming and laborious.

In order to solve the above problems, some special angle measurement tools with simple operation have also appeared in the prior art. For example, CN 204612687U discloses a measurement tool for the angle between the pole stay wire and the ground, which includes a main body of the measuring device, a hanger, an angle indicator The main body of the measuring instrument is a semicircular frame structure, and the surface of the main body of the measuring instrument is provided with an arc-shaped angle scale. The main body of the measuring instrument is equipped with an angle indicator that cooperates with the angle scale. The two ends of the straight side of the frame are equipped with hangers for connecting the stay wires of the electric poles; when in use, the construction personnel hang the device on the stay wires, and the angle indicator uses gravity to indicate, which can help the construction personnel quickly and accurately measure and convert the stay wires The included angle to the ground determines the fixed point of the cable on the ground, eliminating the need for repeated measurement and identification of the cable, solving the problem of cumbersome measurement procedures in existing measurement methods, and greatly improving work efficiency.

However, in actual application, the above-mentioned tools also have defects in use; since the angle indicator uses the principle of gravity indication, no matter whether it is a ball-type, pendulum-type or weight-hammer indicator, the angle indicator cannot be relative It is fixedly connected to the main body of the measuring instrument. Once the main body of the measuring instrument is separated from the pull wire, the indicated value of the angle indicator is easy to change, which limits the application.
