[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 2 , a tunnel cross section measuring device, comprising:

[0028] Measurement Department;

[0029] A handheld part connected to the bottom of the measuring part;

[0030] The handheld part includes a handle 2 and a connecting rod 201;

[0031] The clamping member 2011 is fixedly connected to the connecting rod 201;

[0032] The clamping member 2011 is connected to the measuring part;

[0033] The counterweight part is connected to the bottom of the measuring part.

[0034] The counterweight part includes a counterweight rod 1 and a connecting ring 102 . The counterweight rod 1 is fixedly connected to the bottom of the connecting ring 102 . The connecting ring 102 is rotatably connected to the clamping member 2011 .

[0035] An adjusting gear 4 is fixedly connected to the bottom of the measuring part, and the adjusting gear 4 is rotatably connected to the connecting ring 102 .

[0036] The measuring part includes a body 3 , a laser scanner 303 and a display screen 301 . The laser scanner 303 is fixedly connected to the body 3 , and the display screen 301 is embedded in the body 3 .

[0037] A counterweight block 101 is fixedly connected to the bottom of the counterweight rod 1 .

[0038] The handle 2 is provided with anti-slip patterns.

[0039] The anti-slip grooves can increase the friction between the hand of the measurement personnel and the handle 2, thereby improving the hand-holding stability.

[0040] The body 3 is connected to a signal transmitter 302 .

[0041] The clamping member 2011 is rotatably connected with a movable bolt 5 , and the movable bolt 5 is threadedly connected to the connecting ring 102 .

[0042] Reference Figure 1-Figure 2 During use, after reaching the position to be measured, the body 3 is started. At this time, the laser scanner 303 behind the body 3 will perform a cross-sectional scan. During the scanning process, the counterweight rod 1 and the counterweight block 101 are set, so that the measuring part can maintain vertical measurement of the upper and lower top and bottom plates to ensure the accuracy of the measurement. At the same time, during the measurement process, the measuring part is rotated in the horizontal direction, so that the cross-sectional data in different directions can be measured, and the shape of the cross section can be drawn.

[0043] It should be noted that when the measuring part is adjusted horizontally, it is adjusted by horizontal rotation through the adjusting gear 4, and the adjusting gear 4 is a horizontal distance measurement adjustment gear.

[0044] By scanning and measuring the cross section through the device, the area and shape of the cross section in the tunnel can be measured in real time, which improves the measurement accuracy. At the same time, the handheld part and the counterweight part of the device are used in combination, and there is no need to use a tripod for installation. The structure is simple, which effectively reduces the volume of the tunnel cross section measuring instrument and is easy to carry.

[0045] It should be noted that when the machine body 3 is started for measurement, the machine body 3 will measure the distance values ​​in four directions in real time and display them on the display screen 301. At this time, it can be rotated horizontally according to the measurement data prompts displayed on the display screen 301 to find the shortest distance of the tunnel section. During the adjustment process, it is not limited to adjusting the equipment horizontally up and down or left and right. It is optimal when the equipment measures the shortest left and right distance and is vertical up and down.

[0046] It should also be noted that the measurement unit has a built-in UWB positioning module, which can be connected to a high-precision positioning system to achieve multiple measurements of precise positions.

[0047] It should be noted that the laser scanner 303 is a 360° laser radar that can be purchased in the prior art, and the specific model can be selected according to measurement requirements.

[0048] It should also be noted that the body 3 and the signal transmitter 302 are both common electrical equipment available on the market to ensure normal measurement and use of the body 3 and the signal transmitter 302. At the same time, the specific models are not described in detail in this application.

[0049] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
