Description

Technical Field

[0001] The invention relates to the technical field of iron tower detection equipment, in particular to an iron tower guy wire angle measurement detector. Background Art

[0002] The tower is the infrastructure that supports power transmission and base station signal transfer. In order to ensure the safety, stable transmission and reasonable use of the line, it is usually necessary to use a guy wire to balance the lateral load of the tower and the conductor tension. The tower guy wire uses a steel strand, the upper end of which is connected to the tower's hanging point, the lower end is connected to the hanging point of the buried anchor foundation, and a tensioning regulator is set in the middle. During the daily maintenance of the tower, the guy wire angle is a must-check item.

[0003] In the prior art, measuring instruments such as inclinometers and protractors are used to measure the angle of the wire. During the measurement process, the operation steps of the inclinometer are complicated and time-consuming. The protractor is used in conjunction with a measuring board, but the protractor usually needs to be leveled with the help of a leveling component on the measuring board before use. However, after the leveling component adjusts the position of the protractor, it is often necessary to add an additional self-locking unit to lock and fix the protractor, resulting in a large amount of preparation work required in the early stage of measurement.

The tower wire angle measuring detector disclosed in the present invention adjusts the position of the adjustment block by means of a screw drive, and the screw drive has a self-locking function, which can ensure the stability of the position of the adjustment block and avoid the problem of inaccurate measurement structure caused by displacement.

[0023] 3. Conventional angle measuring instruments are used after they are in contact with the ground. Maintenance personnel need to squat or bend down during the installation of the measuring instrument and the measurement, observation and recording process, which increases the labor intensity of outdoor work. In addition, for mountainous areas with rugged ground, it is difficult to level the installation process of the measuring instrument. For this reason, the present application proposes a structural design that can hook the angle measuring instrument on the guy wire, specifically: adding a hanging component, a clamping component and a positioning component. When the tower guy wire is simultaneously located in the two guy wire accommodating grooves and clamped by two clamping plates, the positioning groove wheel also contacts the tower guy wire. The three components as a whole constitute a clamping and positioning mechanism between the measuring instrument and the tower guy wire, and the maintenance personnel can measure the guy wire angle while standing.

[0024] It should be pointed out that the angle between the hanging plate and the top plate needs to match the angle of the tower guy wire, and the angle of the tower guy wire is a range value (about 45°). When measuring guy wires at different angles, the present invention can adjust the angle between the two hanging plates and the top plate by rotating the top column, and has strong adaptability.

The support plate 21 is fixed to the upper surface of the assembly plate 16 by a plurality of countersunk screws. The connecting seat 22 is fixedly connected to the support plate 21. The connecting seat 22 is a U-shaped structure. The connecting rod 23 and the connecting seat 22 are rotatably connected by a bearing. The middle part of the connecting rod 23 is fixedly connected to the extension rod 25. The end of the connecting rod 23 is provided with a pointer 26 parallel to the extension rod 25. The protractor 24 is fixed to the outside of the connecting seat 22, and the pointer 26 is located on the outside of the protractor 24.

The extension rod 25 drives the connecting rod 23 and the pointer 26 to follow. The second torsion spring 27 is twisted. When the extension rod is in contact with the lower end surface of the tower cable, the pointer 26 indicates the value on the protractor 24, which is the tower cable angle.
