The outer wall of the arc-shaped vertical plate 110 is provided with a vertical first sliding groove 113, a first sliding block 3545 is arranged in the first sliding groove 113 in a sliding manner, a first transverse plate 3541 is fixedly connected to the first sliding block 3545, and the first sliding groove 113 and the first sliding block 3545 are of a T-shaped structure; the first slider 3545 of the T-shaped structure can stably slide inside the first chute 113.
The pin shaft 359 is inserted between the support seat 358 and the connecting rod 320, and the plurality of groups of insertion holes 321 can be used for selectively inserting the pin shaft 359 on the support seat 358. When the corresponding inserted jack 321 is selected, the pin shaft 359 is pulled out in advance, and the height of the supporting seat 358 needs to be adjusted through the connecting part 354; that is, rotating the second knob 3544 drives the second threaded rod 3543 to rotate, that is, the rotating second threaded rod 3543 pushes the top first transverse plate 3541 to move in the vertical direction, that is, drives the second vertical plate 353, the first vertical plate 352 and the support seat 358 to move in the vertical direction. When the supporting seat 358 reaches the designated jack 321, the pin shaft 359 is inserted into the corresponding jack 321 through the supporting seat 358, so that the length of the connecting rod 320 above and below the pin shaft 359 can be adjusted, the length of the arm of force below the pin shaft 359 can be adjusted, the precision of the touch switch 340 of the adjusting feeler lever 330 is realized, and the precision and the accuracy of monitoring and early warning are increased.
The triggering mechanism 30 in the above-mentioned deep foundation pit supporting structure stress mobile monitoring and early warning lacks external protection, and if an external object touches the connecting rod 320, the touch switch 340 is easy to cause false alarm.
Referring to fig. 7 and 8, the device for monitoring and early warning the stress movement of the deep foundation pit supporting structure further comprises a protection mechanism 50, wherein the protection mechanism 50 comprises a U-shaped housing 510, a riser 520, an adjusting bolt 530 and a second slider 540. The base 351 is provided with screw holes 357 far away from first riser 352 one side, and riser 520 sets up in the base 351 and is kept away from first riser 352 one side, and the riser 520 side is provided with the mounting hole 521 multiunit that corresponds with screw holes 357, and the screw rod of adjusting bolt 530 passes mounting hole 521 and is connected with screw holes 357. The U-shaped housing 510 is sleeved outside the first vertical plate 352, the second vertical plate 353 and the vertical plate 520, a second sliding groove 522 is formed in the top of the vertical plate 520, a second sliding block 540 is fixedly arranged on the top wall inside the U-shaped housing 510, and the second sliding block 540 and the U-shaped housing 510 are fixed by adopting screws; and the second slider 540 is engaged with the second chute 522. The second chute 522 and the second slider 540 are preferably T-shaped.
The U-shaped cover 510 and the vertical plate 520 in the protection mechanism 50 can well protect the connecting rod 320 and the switch 340 in the triggering mechanism 30, and prevent external objects from directly touching the switch 340, or indirectly touching the connecting rod 320 and the end of the guide rod 310 to drive the feeler lever 330 to move and touch the switch 340, i.e. reduce the possibility of false alarm caused by touching the switch 340.
The U-shaped cover 510 in the protection mechanism 50 can slide laterally on top of the riser 520, and when the first knob 356 in the adjustment support assembly 350 drives the first threaded rod 355 to rotate to adjust the guide rod 310 to move laterally, the corresponding movement adjustment can be performed by sliding the U-shaped cover 510 on top of the riser 520, so that the U-shaped cover 510 covers the guide rod 310 outside the arc-shaped riser 110 more.
When the second knob 3544 in the adjusting connection portion 354 is turned to drive the second threaded rod 3543 to rotate so as to adjust the positions of the pin shaft 359 and the insertion hole 321 on the supporting seat 358, the adjusting bolt 530 can be simultaneously unscrewed until the adjusting bolt passes through the mounting hole 521 on the riser 520 correspondingly. Under the condition that the heights of the U-shaped housing 510 and the vertical plate 520 are unchanged, after the heights of the components except the connecting part 354 in the supporting component 350 are adjusted, the U-shaped housing 510 and the vertical plate 520 can still well protect the components.
