Above and between the two first screw rods 12, the second gear 15 is fixedly sleeved on the connecting shaft 14, and the first handle 16 is fixedly installed on the top of the connecting shaft 14.
[0028] An outer cover 23 is fixedly installed on the top of the box body 1, the two first gears 13 and the second gear 15 are both located in the outer cover 23, and the top ends of the two first screw rods 12 extend to the Outside the outer cover 23, the top end of the connecting shaft 14 extends outside the outer cover 23.
[0029] A limit baffle 24 is fixedly installed at the bottom ends of the two guide rods 8.
[0030] Balls are nested on both sides of the movable plate 4, and the two balls are in contact with the inner walls on both sides of the corresponding storage cavity 2 respectively.
[0031] Bearings are fixedly sleeved on the two rotating shafts 10, and the outer rings of the two bearings are fixedly connected to the inner wall of the corresponding mounting hole 9 respectively.
[0032] A bearing seat is fixedly installed on the top of the box body 1, and the bottom end of the connecting shaft 14 is rotatably installed on the bearing seat.
[0033] The working principle of a monitoring device for tunnel construction provided by the present invention is as follows:
[0034] A hollow fixed block is installed on the monitoring device. When the monitoring device 5 needs to be transported or moved to the next designated location for monitoring, first, release the fixing of the hollow fixed block in the ground and turn the first clockwise A handle 16, the first handle 16 drives the connecting shaft 14 and the second gear 15 to rotate;
[0035] Since the two first gears 13 mesh with the second gear 15, the second gear 15 drives the two first gears 13 and the two rotating shafts 10 to rotate;
[0036] Since the two first screw rods 12 are respectively threaded and matched with the corresponding first threaded holes 11, when the two rotating shafts 10 rotate, the two first screw rods 12 move upward, and the two The first screw 12 drives the movable plate 4 and the monitoring device 5 to move upward;
[0037] The movable plate 4 slides on the two guide rods 8, and the two guide rods 8 are used to guide the movable plate 4 when it moves vertically. The movable plate 4 drives the two guide rods. The balls roll on the inner wall of the storage cavity 2, and the rolling of the two balls reduces the friction when the movable plate 4 moves, so that the movable plate 4 moves more smoothly;
[0038] When the monitoring device 5 moves up into the box 1, stop turning the first handle 16, and then the box 1 and the monitoring device 5 can be moved or transported. In the process, the enclosure 1 can be used to isolate and protect the monitoring equipment 5 to avoid collisions with the monitoring equipment 5;
[0039] After the monitoring device 5 is transported to a designated position, the four supporting columns 3 are used to support the box body 1 and the monitoring device 5, and the first handle 16 is rotated counterclockwise. Similarly, the The two first screw rods 12 drive the movable plate 4 and the monitoring device 5 to move downwards. When the monitoring device 5 moves out of the proper position outside the box body, the rotation of the first handle 16 is stopped, The monitoring device 5 can then be used for testing.
[0040] Compared with related technologies, a monitoring device for tunnel construction provided by the present invention has the following
[0041] Benefits:
[0042] A monitoring device for tunnel construction. When the monitoring equipment 5 needs to be transported or moved to the next designated place, the first handle 16 is rotated clockwise, and the first handle 16 drives the connecting shaft 14 And the second gear 15 rotate, the second gear 15 drives the two first gears 13 and the two rotating shafts 10 to rotate. When the two rotating shafts 10 rotate, the two first wires The rod 12 drives the movable plate 4 and the monitoring device 5 to move upward, the movable plate 4 slides on the two guide rods 8, and the movable plate 4 drives the two balls in the storage cavity 2. Rolling on the inner wall, when the monitoring device 5 moves up into the box 1, stop rotating the first handle 16, and then the box 1 and the monitoring device 5 can be moved or transported. In the process of handling or transportation, the box 1 can be used to isolate and protect the monitoring equipment 5 to avoid collisions with the monitoring equipment 5. After the monitoring equipment 5 is moved to a designated location, use the four The support column 3 supports the box body 1 and the monitoring device 5, and rotates the first handle 16 counterclockwise. Similarly, the two first screw rods 12 drive the movable plate 4 and the monitoring device. The device 5 moves downwards. When the monitoring device 5 moves out of the appropriate position outside the box body, the first handle 16 is stopped, and then the monitoring device 5 can be used for detection work, which is convenient for adjustment.
