[0027] like Figure 1-6 As shown, this utility model discloses a bracket-type tunnel length measuring device, comprising a measuring instrument body 1 and a supporting tripod 2. The supporting tripod 2 is mounted on the bottom of the measuring instrument body 1. The top of the supporting tripod 2 is provided with an internal threaded ring 5. The inner side of the internal threaded ring 5 is threadedly connected to an external threaded ring 4. The top of the external threaded ring 4 is provided with a fixing ring 3. The outer side of the fixing ring 3 is connected to a first cover 6 via a rotating shaft. The outer side of the fixing ring 3 is connected to a second cover 7 via a rotating shaft. The top of the first cover 6 is provided with a metal plate 10. The side of the first cover 6 is provided with a slot 9. The top of the second cover 7 is provided with a magnetic suction plate 11. The side of the magnetic suction plate 11 is provided with an insert 8. The insert 8 is embedded in the inside of the slot 9. By installing the insert 8 and the slot 9, it is convenient to initially splice the first cover 6 and the second cover 7. The plate 11 magnetically attracts the metal plate 10. The side of the magnetic plate 11 is provided with a push plate 12, and the side of the metal plate 10 is also provided with a push plate 12. By installing a first cover 6 and a second cover 7 on the outside of the measuring instrument body 1, and connecting a fixing ring 3 at the bottom of the first cover 6 and the second cover 7 through a rotating shaft, and threading an inner thread ring 5 at the bottom of the fixing ring 3, the outer thread ring 4 at the bottom of the fixing ring 3 is screwed to connect with the inner thread ring 5. In this way, the dustproof structure can be installed on the outside of the measuring instrument body. After the measuring instrument is used, the staff first rotates the first cover 6 inward, and then flips the second cover 7. The first cover 6 and the second cover 7 are initially spliced ​​together by magnetic attraction, which can perform dustproof work on the measuring instrument body 1.

[0028] The first cover 6 has a first side plate 25 on its side, the second cover 7 has a first side plate 25 on its side, and the fixing ring 3 has a second side plate 26 on its side. The second side plates 26 are symmetrically distributed. The first side plate 25 is connected to the second side plate 26 through a pivot. Because of the installation of the first side plate 25 and the second side plate 26, it is convenient to flip the first cover 6 and the second cover 7 outward through the pivot.

[0029] The outer side of the tripod 2 is provided with a threaded seat 13, and the threaded seat 13 is internally connected to a threaded block 14. There are two sets of threaded seats 13. The outer side of the threaded block 14 is provided with a connecting rod 15, and the other side of the connecting rod 15 is provided with a magnetic block 18. By installing the threaded seat 13 and the threaded block 14, it is convenient to connect the connecting rod 15 by means of threaded connection.

[0030] The connecting rod 15 is provided with a fixing block 16, and a ball-shaped grip 17 is provided on the outside of the fixing block 16. The ball-shaped grip 17 is distributed in a ring shape. Because of the fixing block 16, it is convenient to connect the ball-shaped grip 17 and the connecting rod 15.

[0031] The inner sides of the first cover 6 and the second cover 7 are provided with reinforcing plates 20, and the outer side of the reinforcing plates 20 is provided with metal sheets 19. The magnetic blocks 18 magnetically attract the metal sheets 19. By installing the magnetic blocks 18 and the metal sheets 19, the cover structure can be fixed in position by strong ferromagnetic attraction.

[0032] The top of the tripod 2 is provided with a connecting seat 21. The measuring instrument body 1 is installed inside the connecting seat 21. A sleeve 22 is provided on the outside of the connecting seat 21. A mounting plate 23 is provided on the outside of the sleeve 22. A pressing screw 24 is provided inside the mounting plate 23. The pressing screw 24 is threadedly connected to the connecting seat 21. Because of the mounting plate 23, sleeve 22 and pressing screw 24, the measuring instrument body can be installed and fixed inside the tripod 2 by turning the mounting plate 23 and the pressing screw 24 inside the sleeve 22.

[0033] The working principle of this bracket-type tunnel length measuring device is as follows: When using the device, first hold the supporting tripod 2 and assemble the measuring instrument body 1 with the supporting tripod 2. Then, transport it into the tunnel. Next, use fasteners to install it on a flat surface. This increases the stability of the measuring device and prevents it from tipping over during measurement, which would affect the measurement. Then, start the measuring instrument body 1 to perform the measurement. First, it needs to emit an infrared signal. The device emits a high-frequency modulated infrared pulse signal through an infrared emitting diode. This signal propagates towards the target object at the speed of light. Then, the signal is reflected and received. When the infrared signal encounters the tunnel wall or obstacle, it is reflected and captured by the receiving diode. The reflected signal is affected by atmospheric attenuation during propagation, with the attenuation degree being proportional to the square of the distance. Distance is then calculated by measuring the time difference between transmission and reception using a formula. The time difference is converted into a length value through digital circuitry. In tunnel applications, this device is used for non-contact measurement of wall spacing, crack length, or equipment layout. Its advantages include rapid response and adaptability to complex environments, but its accuracy is affected by temperature, atmospheric pressure, and surface reflection characteristics. To protect the idle measuring instrument body 1 from dust, a first cover 6 and a second cover 7 are installed on the outside of the measuring instrument body 1. The first cover 6 has slots 9 and metal plates 10 on its side, and the second cover... The side of the measuring instrument 7 is equipped with an insert 8 and a magnetic plate 11, and a fixing ring 3 is connected to the bottom of the first cover 6 and the second cover 7 via a rotating shaft. An internal threaded ring 5 is threaded to the bottom of the fixing ring 3. Before using the measuring instrument body 1, the operator first screws the fixing ring 3 to thread the bottom external threaded ring 4 and internal threaded ring 5 together. This allows the dustproof structure to be installed on the outside of the measuring instrument body. After the measuring instrument is used, the operator first rotates the first cover 6 inward, then flips the second cover 7, and then inserts the insert 8 into the slot 9. Next, the magnetic plate 11 is magnetically attached to the metal plate 10, thus initially connecting the first cover 6 and the second cover 7. The splicing process allows for dust protection of the measuring instrument body 1. Finally, when the measuring instrument body is no longer needed, the first cover 6 is flipped outwards, followed by the second cover 7. To secure the unused first cover 6 and second cover 7, the operator takes out the magnetic block 18, pinches the ball-shaped handle 17, and connects the threaded block 14 on the side of the connecting rod 15 to the threaded seat 13. This allows the magnetic block 18 to be installed on the outside of the measuring instrument device. A reinforcing plate 20 is installed on the side of the cover structure, and a metal sheet 19 is provided on the outside of the reinforcing plate 20. This allows the unused first cover 6 and second cover 7 to be secured magnetically.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
