Detailed ways

A kind of instrument height measuring device as shown in Figure 1, comprises positioning bar 1 and measuring rope 2, and one end of described positioning bar 1 is provided with clamping head 3, and snap ring 4 is installed on the described clamping head 3, so The snap ring 4 is provided with a positioning piece 5 for contacting with the plane where the measurement control point is located, one end of the measuring rope 2 is connected with the positioning piece 5, the measuring rope 2 is marked with a scale, and the measuring rope 2 Features a non-elastic cord.

When in use, hold the positioning rod 1 in one hand and the measuring rope 2 in the other hand, and move the positioning rod 1 so that the positioning piece 5 is in close contact with the measurement control point. The steel bar head of the control point is fixed on the ground. At this time, the positioning piece 5 is in close contact with the measurement control point on the ground. At this time, the other hand straightens the measuring rope 2, and records the distance between the measuring rope 2 and the height measuring line of the instrument. Location. Read the length of the entire section through the scale on the measuring rope 2. For the length of the non-integral section, you only need to use a ruler to measure the length of the non-integral section, and add the number of entire sections to get the precise height of the instrument . Compared with directly measuring with a steel ruler, the measuring device is more convenient and flexible. Wherein, the measuring rope 2 adopts an inelastic rope to avoid elastic deformation of the measuring rope 2 and affect the accuracy of the measurement data.

In this embodiment, the positioning piece 5 is made of a permanent magnet, so that the positioning piece 5 is magnetically connected to the steel bar head of the measurement control point, which can ensure that the positioning piece 5 is closely attached to the measurement control point, and allows the operator to compare Save effort.
