Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] As Figures 1-4 shown, a technical scheme provided by the utility model:

[0023] A crack monitoring device, including rack 1, one side of rack 1 is integrally formed with fixed disc 2, the middle part of fixed disc 2 is movably installed with rotary table 3, the two sides of rotary table 3 are symmetrically provided with guide groove 4, the inside of two guide grooves 4 is provided with monitoring mechanism, monitoring mechanism includes movable strip 6, connecting piece 7, clamping needle 8 and second spring 9, the inside of two guide grooves 4 is movably connected with movable strip 6 through second spring 9 respectively, connecting piece 7 is arranged at the outer wall of one side of movable strip 6, the end of connecting piece 7 away from movable strip 6 is fixedly connected with clamping needle 8, monitoring mechanism further includes pointer 10 and first scale 11, pointer 10 is symmetrically arranged at the outer wall of the two sides of movable strip 6, first scale 11 is symmetrically arranged at the outside of the two sides of rotary table 3 located in guide groove 4;

[0024] In the embodiment, when the monitored wall crack produces further change, for example, expands to both sides, at this time, the expanding crack laterally spreads two clamping needles 8, when clamping needle 8 moves, movable strip 6 is driven to move synchronously through connecting piece 7, and then the position of pointer 10 indicated on first scale 11 can be observed to confirm the change of crack, so that the crack can be monitored in real time when the crack expands to both sides.

[0025] As Figure 2 and Figure 3As shown, the middle of the turntable 3 is symmetrically provided with a guide disc 5 on both sides of the outer wall, the guide disc 5 on both sides of the turntable 3 is in sliding connection with the outer wall of both sides of the fixed disc 2, the right guide disc 5 is provided with a direction adjusting mechanism between the fixed disc 2, the direction adjusting mechanism comprises a second scale 12 and a pointer 13, the second scale 12 is provided on the right outer wall of the fixed disc 2, the pointer 13 is provided on the outer wall of the right guide disc 5,

[0026] In this embodiment, when the monitored wall crack produces further changes, for example, the crack is displaced in the up-down direction, at this time, the up-down displacement crack will drive the two clamping needles 8 to move in the same direction, because the guide disc 5 is in movable connection with the fixed disc 2, and the guide disc 5 can only realize the rotation of the angle under the guidance of the fixed disc 2, so when the two clamping needles 8 are stressed, the guide disc 5 rotates synchronously, and the change of the crack is confirmed through the second scale 12 and the pointer 13, so that the crack can be monitored in real time when the crack is displaced in the up-down direction.
