[0030] Box 1 is also provided with three marks, including unit full name mark and function item mark, safety and prohibition of random touch mark, effective calibration or self-check mark;And two standards are unified: one is standardized wire cable interface, and the other is special standardized small distribution box (grounding and air switch).

[0031] In the process of installing the alarm box for tunnel safety monitoring and early warning management, first, mark the positions of the two top embedded bolts of the box body 1 on the wall according to the measured distance, then drill holes at the corresponding positions and install the expansion bolts. Then, the two first installation holes 2.1 are respectively sleeved with the two top expansion bolts, then the box body 1 is loosened, and under the action of gravity, the box body 1 is centered in the width direction through the cooperation of the first installation assembly 2 and the second installation assembly 3, so that the box body 1 is located in the middle position between the two top expansion bolts, thereby ensuring the stable suspension of the box body 1. Then, the nuts of the top expansion bolts are installed, and the two sides of the top of the box body 1 are fixed.

[0032] Then, according to the position of the second installation hole 3.1, the installation hole of the bottom expansion bolt of the box body 1 is drilled, and after the two bottom expansion bolts are installed, the nuts of the bottom expansion bolts are installed, and the two sides of the bottom of the box body 1 are fixed.

[0033] In this embodiment, after the box body 1 is connected and fixed with the top expansion bolts, the box body 1 is in a centered state, and then the installation positions of the two bottom expansion bolts are determined based on the centered state of the box body 1, so that after the box body 1 is finally installed, the box body 1 is more balanced and stable in suspension and fixation.

[0034] The first installation assembly 2 includes a first installation plate 2.2 and a first connecting plate 2.3, the first installation plate 2.2 is fixedly installed on the back of the box body 1, and the first installation plate 2.2 is inclined upward by 45° at the outer side end, the second installation plate 3.2 is slidably sleeved on the first installation plate 2.2, and the first installation hole 2.1 is arranged on the outer side end of the first installation plate 2.2.

[0035] In the initial state, the first connecting plate 2.3 is located at the lowest position on the first installation plate 2.2 under the action of gravity. In the process of connecting the first installation assembly 2 with the top expansion bolts, the first connecting plate 2.3 is pulled upwardly and obliquely, so that the first installation hole 2.1 is aligned with the top expansion bolt, and then the first installation hole 2.1 is sleeved with the top expansion bolt. Then, the box body 1 is slowly lowered, and the first installation plates 2.2 on both sides are synchronously slid downward on the first connecting plate 2.3, thereby centering the box body 1, so that the box body 1 is stably and balancedly suspended by the top expansion bolts.

[0036] The outer side end of the first connecting plate 2.3 is provided with a horizontal support surface 2.4, the first installation hole 2.1 is a strip-shaped hole, and the bottom end of the strip-shaped hole penetrates through the support surface 2.4.

[0037] In this way, when the first mounting hole 2.1 is sleeved on the top expansion bolt, the supporting surface 2.4 of the two first connecting plates 2.3 is automatically outwardly displaced on the top expansion bolt. When the first mounting hole 2.1 moves to the top of the top expansion bolt, the first connecting plate 2.3 moves downward, so that the first mounting hole 2.1 is sleeved downward on the top expansion bolt until the top expansion bolt is supported on the inner top wall of the first mounting hole 2.1, so that the top expansion bolt cooperates with the first connecting plate 2.3 to suspend the two sides of the top of the box body 1.

[0038] After the application of the present embodiment, the first mounting assembly 2 not only allows construction errors during connection of the top expansion bolt, but also is extremely convenient to operate. After the first connecting plate 2.3 is placed on the top bolt, the box body 1 can be directly slowly lowered downward.

[0039] The bottom of the outer side end of the first connecting plate 2.3 is fixedly provided with an extension plate 4, the lower surface of the extension plate 4 is flush with the supporting surface 2.4, and the length of the extension plate 4 is adapted to the supporting surface 2.4. The first extension plate 4 is used to increase the contact area between the first connecting plate 2.3 and the top expansion bolt when the supporting surface 2.4 moves on the top expansion bolt, thereby improving the pre-supporting effect and stability of the top expansion bolt on the first connecting plate 2.3.

[0040] The first connecting plate 2.3 is provided with a strip-shaped groove 5 inclined upward by 45° at the outer side end, the strip-shaped groove 5 is sleeved on the first mounting plate 2.2, and the bottom inner wall surface of the first strip-shaped groove 5 is provided with a buffer block 6. By arranging the buffer ring, when the box body 1 is suspended by the top expansion bolt, the first mounting block is located at the lowest position of the strip-shaped groove 5 and is supported on the buffer block 6.

[0041] At this time, in combination with the sizes of the first mounting hole 2.1 and the second mounting hole 3.1 being greater than the outer diameter of the expansion bolt, after the box body 1 is mounted on the cavity, the first mounting plate 2.2 is slightly moved up and down in the first connecting plate 2.3 along the strip-shaped groove 5, so that the first connecting plate 2.3 is slightly translated left and right on the top expansion bolt, and the buffer block 6 is used to buffer the slight movement of the box body 1. The first mounting hole 2.1 and the second mounting hole 3.1 are respectively provided with a first buffer pad 7 and a second buffer pad 8. In this way, the buffering effect of the slight movement after the box body 1 is mounted is improved, and an effective buffering effect is provided for the box body 1.

[0042] In a relatively specific embodiment, the second mounting assembly 3 comprises a second mounting plate 3.2 and a second connecting plate 3.3, the second mounting hole 3.1 is arranged on the second connecting plate 3.3, and the second mounting hole 3.1 is a circular hole, and the second connecting plate 3.3 is fixedly mounted on the second mounting plate 3.2.
