This setting realizes the automatic control of the measuring rope 5, reduces the complexity of manual operation, improves the measurement efficiency, and ensures the uniformity and stability of the extension and retraction of the measuring rope 5, further improving the accuracy of the measurement.

[0034] Embodiment two

[0035] Please refer to Figures 1-5 The bottom of the mounting frame 3 is fixedly connected with a mobile base 1, and the guide wheel structure comprises two guide wheels 10. Specifically, the mobile base 1 and the two guide wheels 10 with different heights and a spacing are provided, and in use, the mobile base 1 facilitates the movement and positioning of the entire measuring device, and the two guide wheels 10 ensure that the measuring rope 5 maintains a stable path and tension when passing. This setting improves the portability and practicality of the measuring device, and further improves the accuracy and stability of the measurement.

[0036] The two guide wheels 10 are different in height and have a spacing therebetween, and are each rotatably connected to the inner wall of the mounting frame 3 through a rotating rod. Specifically, the two guide wheels 10 are rotatably connected to the inner wall of the mounting frame 3 through a rotating rod. In use, the guide wheels 10 can freely rotate to adapt to the extension direction of the measuring rope 5, thereby reducing the friction and resistance of the measuring rope 5 when passing. This arrangement improves the passability and stability of the measuring rope 5, further prolongs the service life of the measuring rope 5, and reduces the energy consumption and cost in the measurement process.

[0037] Embodiment three

[0038] Referring to Figures 1-5 The extension frame 4 includes an extension wheel 11 and two extension rods 12. The two extension rods 12 are arranged on both sides of the extension wheel 11 and are rotatably connected to the extension wheel 11 through a bent rod. The outer circle of each of the two extension rods 12 is slidably connected to a guide sleeve 9 connected to the inner wall of the mounting frame 3. Specifically, the extension wheel 11 and the two extension rods 12 in the extension frame 4 are cooperatively arranged with the guide sleeve 9. During the measurement process, the extension rods 12 can slide in the guide sleeve 9, and the extension wheel 11 can rotate to adapt to the extension direction of the measuring rope 5. This arrangement enhances the flexibility and adaptability of the extension frame 4, so that the measuring rope 5 can maintain stable tension and direction during the extension process, effectively avoiding measurement errors caused by the curvature or length change of the roadway.

Through the rotation between the movable rod 13 and the extension rod 12, the push-pull rod 2 can be placed at the bottom of one side of the mounting frame 3, thereby saving space. After the extension rod 12 and the movable rod 13 are connected by the locking screw rod 19, the extension distance of the extension rod 12 can be expanded. The device not only saves space when folded, but also quickly connects and extends the pushing distance. This arrangement enables the measuring device to be flexibly adjusted according to the length and shape of different roadways, further improving the adaptability and accuracy of the measurement.

[0040] The present scheme has the following working process:

[0041] When using the present roadway tunneling measuring device, first, the mounting frame 3 is stably moved and installed at a proper position of the roadway tunneling through the bottom fixedly connected mobile base 1, ensuring the stability and safety of the entire device. Then, one end of the measuring rope 5 wound on the line roller 8 is fixed, and it is ensured that the winding is tight and has no looseness. At this time, the driving motor 7 is rotationally connected with the line roller 8, ready for automatic control.

[0042] When the measurement starts, the driving motor 7 is started to drive the line roller 8 to rotate, thereby controlling the measuring rope 5 to gradually unroll from the line roller 8, and the taper rod 6 slowly falls. The measuring rope 5 passes through a plurality of guide wheel structures in the mounting frame 3 in turn. The guide wheel structures are composed of two guide wheels 10 with different height positions and a spacing. They are rotationally connected with the inner wall of the mounting frame 3 through a rotating rod, ensuring the smoothness and directionality of the measuring rope 5 during the unrolling process, reducing friction and resistance, and improving the passability and stability of the measuring rope 5.

[0043] Subsequently, the measuring rope 5 continues to extend to the extension frame 4. The extension frame 4 comprises an extension wheel 11 and two extension rods 12, the extension rods 12 are rotationally connected with the extension wheel 11 through a bent rod and can slide in a guide sleeve 9 connected with the inner wall of the mounting frame 3. This arrangement enhances the flexibility and adaptability of the extension frame 4, so that the measuring rope 5 can maintain stable tension and direction during extension.

[0044] During the measurement, the distance is adjusted according to the actual required horizontal direction, and the extension frame 4 is freely extended under the horizontal activity cooperation of the inner wall of the mounting frame 3. At this time, the flexible adjustment of the length of the extension frame 4 can be realized by sliding and rotating the movable rod 13 and the connecting rod 17 in the connecting groove 14 and the sliding groove 15 in the extension rod 12 through the push-pull rod 2. After the adjustment is completed, the connecting rod 17 is fixed in the side groove 16 of the extension rod 12 through the locking screw 19, so as to ensure the stability of the extension frame 4.
