Abstract
Description
Technical Field
[0001] This application relates to the field of tunnel face measurement technology, and in particular to a multi-directional measurement terminal for tunnel faces. Background Technology
[0002] The term "working face" originated from coal miners' vivid description of a narrow working face and was later extended to the excavation faces of tunnels, mines, and other similar structures. Essentially, it is the dynamic interface between excavated and unexcavated rock strata, which continuously moves forward as excavation progresses.
[0003] Geological sketching, geophysical exploration (such as ground-penetrating radar), and advanced drilling can be used to obtain information on the lithology, fracture zones, and water-rich zones of the strata ahead of the tunnel face, providing a basis for support design. However, existing measuring devices for the tunnel face are usually fixed, making it inconvenient to adjust the rotation angle, which affects the accuracy of the measurements. Utility Model Content

[0008] In some embodiments, the connecting assembly includes a pair of first connecting plates, which are spaced apart on the fixed plate. A first slot is formed between the pair of first connecting plates. A second connecting plate is provided on the front side of the first connecting plate. A second slot is provided in the middle of the second connecting plate. A first card is inserted into the first slot. The first card is adapted to the first slot.

[0013] In some embodiments, a circuit board is disposed on the upper part of the upper housing, and the laser emitter is disposed on the lower part. An emission hole is disposed on the front side of the upper housing, and the laser emitter is mounted at the emission hole.
[0014] In some embodiments, a sealing cover is provided at the lower end of the lower housing, one side of the sealing cover is hinged to the lower housing, and a latch is provided on the other side, the latch engaging with the lower housing.

[0028] Figures 1-6 An embodiment of the tunnel face multi-directional measurement terminal of this application is shown, including a mounting base 1, an upper housing 3, and a lower housing 2. Both the upper housing 3 and the lower housing 2 are hollow structures. The mounting base 1 is used to connect its support. A first rotating component 4 is provided on the outside of the mounting base 1. The first rotating component 4 is connected to the lower housing 2. The first rotating component 4 is used to make the lower housing 2 rotate around the longitudinal central axis of the first rotating component 4. A battery (not shown in the figure) is provided inside the lower housing 2. A second rotating component 5 is provided at the upper end of the lower housing 2.

A circuit board 6 and at least one laser emitter 7 are provided inside the upper housing 3. The circuit board 6 is electrically connected to the battery and the laser emitter 7 respectively.
[0029] In this application, the lower housing 2 and the upper housing 3 on the lower housing 2 can be rotated around the longitudinal central axis of the first rotating assembly 4 by the first rotating assembly 4, and the upper housing 3 can be rotated around the vertical central axis of the second rotating assembly 5 by the second rotating assembly 5. This allows adjustment of the rotation angle of the laser emitter 7 inside the upper housing 3, so that the position of the laser emitter 7 can be flexibly adjusted according to different measurement environments, so that the structured light emitted by the laser emitter 7 can be accurately projected onto the tunnel face, thereby ensuring the accuracy of the tunnel face measurement.
[0030] In some embodiments, such as Figure 3 As shown, the mounting base 1 includes a fixing component 11 and a connecting component 12. The fixing component 11 is fixedly mounted on its support, which can be described as a mounting frame or the inner wall of a tunnel. The connecting component 12 is detachably connected to the fixing component 11 to facilitate connection between them. The detachable connection between the connecting component 12 and the fixing component 11 can be achieved through bolt connection or interference fit snap-fit.
[0031] In some embodiments, such as Figure 3 As shown, the fixing component 11 includes a fixing plate 111 and a mounting plate 112. The mounting plate 112 is disposed on the rear side of the fixing plate 111 and is used to connect the support. The mounting plate 112 and the fixing plate 111 corresponding to the mounting plate 112 are provided with a horizontal connecting hole 113 on one side and a vertical mounting hole 114 on the other side. The horizontal connecting hole 113 and / or the vertical mounting hole 114 are elongated, thereby allowing adjustment of the horizontal and vertical positions of the fixing plate 111 relative to the mounting plate 112. After the mounting plate 112 is fixed, the horizontal and vertical positions of the fixing plate 111 can be adjusted, which facilitates the adjustment of the position of the measuring terminal.
[0032] In some embodiments, such as Figure 3 As shown, the connecting assembly 12 includes a pair of first connecting plates 121, which are spaced apart on the fixed plate 111. The pair of first connecting plates 121 enclose a first slot 122. A second connecting plate 123 is provided on the front side of the first connecting plate 121, and a second slot 124 is provided in the middle of the second connecting plate 123. A first locking plate 125 is inserted into the first slot 122 and is adapted to the first slot 122. A second locking plate 126 is provided on the first locking plate 125 and is adapted to the second slot 124. A first rotating assembly 4 is provided on the second locking plate 126 and is connected to the lower housing 2. The first locking plate 125 and the second locking plate 126 can be inserted into and removed from the first slot 122 and the second slot 124, respectively, thereby improving the convenience of installing the lower housing 2 on the mounting base 1.
[0033] In some embodiments, such as Figure 3 As shown, the size of the first slot 122 is larger than that of the second slot 124, and the size of the first plate 125 is larger than that of the second plate 126. When the first plate 125 and the second plate 126 are respectively engaged in the first slot 122 and the second slot 124, the first plate 125 can be limited by the second connecting plate 123 to prevent the first plate 125 from coming out of the first slot 122, thereby improving the stability of the mounting base 1.
[0034] In some embodiments, the first slot 122, the second slot 124, the first plate 125, and the second plate 126 are all isosceles trapezoids, thereby enabling the first plate 125 and the second plate 126 to be supported by the sides of the first slot 122 and the second slot 124 respectively, further ensuring the stability of the mounting base 1.
[0035] In some embodiments, a rotating connecting plate 127 is provided on the front side of the second card plate 126. The rotating connecting plate 127 is connected to the first rotating assembly 4. The rotating connecting plate 127 protrudes from the second card plate 126, thereby facilitating the installation of the lower housing 2.
[0036] In some embodiments, a first rotating assembly 4 is provided on the rotating connecting plate 127. The first rotating assembly 4 can be a damping bearing, a rotary damper, a friction damper, etc. The first rotating assembly is arranged longitudinally, and its axis is the longitudinal central axis. The fixing ring of the first rotating assembly 4 can be set on the rotating connecting plate 127, and the rotating ring is set on the lower housing 2. The relative rotation of the rotating ring and the fixing ring causes the lower housing 2 to rotate circumferentially relative to the mounting base 1.
[0037] In some embodiments, such as Figure 2 As shown, an inner housing 21 is provided inside the lower housing 2, and a storage battery is installed inside the inner housing 21. The inner housing 21 can protect the storage battery.
[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, a sealing cover 22 is provided at the lower end of the lower housing 2. One side of the sealing cover 22 is hinged to the lower housing 2, and a latch 23 is provided on the other side. The latch 23 is engaged with the lower housing 2, thereby allowing the sealing cover 22 to be opened easily to install the battery.
[0039] In some embodiments, such as Figure 4 As shown, a rotating connection part 25 is provided at the rear of the lower housing 2. The rotating connection part 25 is connected to the first rotating assembly 4, and the rotating connection part 25 protrudes from the lower housing 2. This facilitates the connection between the lower housing 2 and the first rotating assembly 4.
[0040] In some embodiments, an antenna 8 is provided on the front side of the lower housing 2, and the antenna 8 is used to increase the signal received or transmitted by the circuit board 6.
[0041] In some embodiments, such as Figure 2 and Figure 4 As shown, the upper end of the lower housing 2 is provided with a mounting hole 24, and the second rotating assembly 5 is vertically disposed at the mounting hole 24. The second rotating assembly 5 can be a damping bearing, a rotary damper, a friction damper, etc. The axis of the second rotating assembly 5 is the vertical central axis. The fixed ring of the second rotating assembly 5 can be disposed on the lower housing 2, and the rotating ring can be disposed on the upper housing 3. The relative rotation of the rotating ring and the fixed ring causes the upper housing 3 to rotate circumferentially relative to the lower housing 2.
[0042] In some embodiments, such as Figure 2 As shown, a central hole 51 is provided at the center of the second rotating component 5. The central hole 51 is used to pass through a connecting wire (not shown in the figure), which connects the battery and the circuit board 6.
[0043] In some embodiments, such as Figure 6 As shown, a circuit board 6 is provided on the upper part of the upper housing 3, and a laser emitter 7 is provided on the lower part. An emission hole 31 is provided on the front side of the upper housing 3. The laser emitter 7 is installed at the emission hole 31. There are three laser emitters 7, and the three laser emitters 7 can emit horizontal lasers, vertical lasers, or grid lasers, respectively.
[0044] In some embodiments, such as Figure 1 and Figure 6 As shown, an upper cover 32 is provided on the upper end of the upper housing 3, and a control button 61 is provided on the circuit board 6. The control button 61 extends to the lower end surface of the upper cover 32, and a button 33 corresponding to the control button 61 is provided on the upper cover 32. The operation of the laser emitter 7 can be controlled by the button 33.
[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, a display screen 34 is also provided on the upper cover 32. The display screen 34 is electrically connected to the circuit board 6 and is used to display the operating status and equipment information of the laser emitter 7.
[0046] Therefore, this application discloses a multi-directional measurement terminal for tunnel face. In this application, the lower housing and the upper housing on the lower housing can be rotated around the longitudinal central axis of the first rotating component by the first rotating component, and the upper housing can be rotated around the vertical central axis of the second rotating component by the second rotating component. This allows adjustment of the rotation angle of the laser emitter inside the upper housing, thereby flexibly adjusting the position of the laser emitter according to different measurement environments, so that the structured light emitted by the laser emitter can be accurately projected onto the tunnel face, thus ensuring the accuracy of the measurement of the tunnel face.
[0047] The above are merely embodiments of this application and do not limit the scope of this patent application.
