[0043] In this embodiment, the measuring rod 30 is a movable structure, and the positioning rod 20 remains fixed. At this time, when the measuring rod 30 and the positioning rod 20 clamp a certain beam frame, the thickness of the beam frame can be obtained by measuring the distance between the clamping points (that is, the distance between the facing end faces of the positioning rod 20 and the measuring rod 30); when the support is placed between the beam frames, the height of the spacing can be obtained by measuring the distance outside the clamping points (that is, the distance between the opposite end faces of the positioning rod 20 and the measuring rod 30, which is actually the sum of the distance between the facing end faces of the positioning rod 20 and the measuring rod 30 and the thickness of the positioning rod 20 and the thickness of the measuring rod 30). When the positioning rod 20 and the measuring rod 30 are both perpendicular to the support rod 10, the accuracy of the detection data can be ensured, and the detection data of any clamping point remains the same.

[0044] More specifically, it also includes a control device; the control device is installed on the positioning rod 20; the control device is linked with the measuring rod 30 to control the measuring rod 30 to move along the length direction of the positioning rod 20.

[0046] Preferably, in this embodiment, the pulley 41 is fixed to the top end of the support rod 10 via a supporting structure, and the supporting structure avoids the outer side surface of the pulley 41 and does not affect the rotation of the pulley 41 .

[0047] Preferably, in this embodiment, the positioning rod 20 is provided with a through hole 21 for the ruler 42 to pass through, and the through hole 21 and the support rod 10 are arranged to avoid each other, so that the ruler 42 passes through the through hole 21 and is vertically arranged on one side of the support rod 10 without being blocked by the support rod 10.

[0050] In this embodiment, due to the provision of the pulley 41 at the top of the support rod 10, the user can easily control the up and down movement of the measuring rod 30 by pulling the ruler 42, thereby achieving the measurement needs of the high beam.

[0051] More specifically, scale marks are formed on the ruler 42 .

[0052] Preferably, a tape measure is used as the ruler 42 .

[0054] More specifically, a positioning hole 31 is provided on the measuring rod 30, and the positioning hole 31 is sleeved on the support rod 10; a ruler bar limiting clamp 32 is provided in the positioning hole 31, and the setting position of the ruler bar limiting clamp 32 coincides with the extension direction of the other end of the ruler bar 42; the ruler bar limiting clamp 32 includes two clamping members 321 which are arranged on the same horizontal plane and are closely arranged; the ruler bar 42 vertically passes through the contact surfaces of the two clamping members 321.

[0055] Preferably, the positioning hole 31 in this embodiment allows the measuring rod 30 to be slidably disposed along the length direction of the supporting rod 10 .

[0056] Preferably, in this embodiment, the ruler bar limiting clamp 32 is arranged on the open end face of the positioning hole 31 and is located on the same vertical line as the end face of the pulley 41, ensuring that the ruler bar 42 passes through the contact surfaces of the two clamping members 321 when it droops naturally.

[0058] In this embodiment, the first ruler limit clamp 32 and the second ruler limit clamp 32 can be used to tighten the ruler 42, so that the change of the scale on the ruler 42 is equivalent to the height change of the measuring rod 30, ensuring the accuracy of the detection result of the measuring tool. Among them, the use of the clamping member 321 for clamping can further limit the moving direction of the ruler 42 and its tightness.

[0059] More specifically, the measuring rod 30 is further provided with an auxiliary wheel 33 ; the auxiliary wheel 33 is disposed in the positioning hole 31 , and a limiting groove 11 for the auxiliary wheel 33 to roll is opened on the support rod 10 .

At this time, the auxiliary wheel 33 can slide up or down along the length direction of the limiting groove 11 to assist the movement process of the measuring rod 30 and limit the movement path of the measuring rod 30.

[0062] In summary, this embodiment proposes a measuring tool for surveying beams at high altitudes, which realizes the up and down movement of the measuring rod by pulling the ruler, and realizes effective measurement of the beams and their spacings by clamping or spreading the positioning rod and the measuring rod, and intuitively obtains the values ​​of the beams and their spacings by reading the scale changes on the ruler.
