Referring to fig. 1, an application scenario diagram of a deformation detection apparatus for a supporting structure provided in an embodiment of the present application is shown, where the application scenario includes: the rock mass 001, the supporting structure 002 and the deformation detection device 000 of the supporting structure at the periphery of the underground cavern.
As shown in fig. 1, the supporting structure 002 supports the rock mass 001 around the underground cavern, ensuring the stability of the underground cavern during construction work. The deformation detection device 000 of the supporting structure is arranged at one end of the supporting structure, and when the supporting structure 002 deforms due to the extrusion of the rock mass 001 at the periphery of the underground cavern, the deformation detection device 000 can detect the deformation of the supporting structure 002. Alternatively, the supporting structure 002 includes an arch ring 0021, and the deformation detecting device 000 may be connected to one end of the arch ring 0021.
Please refer to fig. 2, which illustrates a schematic structural diagram of a deformation detection apparatus for a supporting structure according to an embodiment of the present application. This supporting construction's deformation detection device 000 includes: a support plate 100, a first elastic member 200, a pulley assembly 300, and a deformation determining assembly 400.
One side of the supporting plate 100 is connected to one end of the arch ring 0021 in the supporting structure 002, and the other side is in contact with the first elastic element 200, and one side of the supporting plate 100 close to the first elastic element 200 is connected to the first end of the pulley assembly 300.

In this embodiment, if the rock mass around the underground cavern is broken, when the broken rock mass extrudes the supporting structure 002 to cause it to deform, the supporting plate 100 of the deformation detection device 000 moves toward the direction close to the first elastic element 200, and the moving supporting plate 100 can drive the first sliding block 403 to move through the pulley assembly 300, so as to drive the pointer 4042 connected to the first sliding block 403 to move. The pointer 4042 after the removal can cooperate with calibrated scale 4041 to indicate the deformation degree of supporting construction 002, makes the staff can monitor this supporting construction's deformation degree at any time through observing the graduation apparatus, and then guarantees the safety of staff when carrying out construction work in the underground cavern.
To sum up, the application provides a supporting construction's deformation detection device, this supporting construction's deformation detection device includes: the support plate, the first elastic element, the pulley assembly and the deformation determining assembly. The deformation determining assembly includes a case, a second elastic element and a first slider located in the case, and a scale located outside the case, the scale having a dial and a pointer. When the rock mass extrusion supporting structure of peripheral broken of underground cavern leads to it to take place deformation, the backup pad among the deformation detection device can move to the direction that is close to first elastic element, and the backup pad that takes place to remove can drive first slider through loose pulley assembly and remove, and then drives the pointer removal of being connected with this first slider. The pointer after removing can cooperate with the calibrated scale to indicate supporting construction's deformation degree, make the staff can monitor this supporting construction's deformation degree at any time through observing the graduation apparatus, and then guarantee the safety of staff when carrying out construction work in the underground cavern.
Optionally, as shown in fig. 2, the deformation detecting apparatus 000 further includes: the fixing base 500 has a mounting groove a, and the supporting plate 100 and the first elastic member 200 are located in the mounting groove a of the fixing base 500. As shown in fig. 2, the area of the bottom surface of the mounting groove a is larger than the area of the plate surface of the supporting plate 100, and the depth of the mounting groove a is larger than or equal to the sum of the thicknesses of the supporting plate 100 and the first elastic element 200, so that the supporting plate 100 and the first elastic element 200 can be ensured to be accommodated in the mounting groove a. The fixing base 500 having the installation groove a may be a brick-laid base, or may be a base cast by concrete, or may be a steel base.
In the embodiment of the present application, the supporting plate 100 is used to bear one end of the arch ring 0021, the supporting plate 100 and the arch ring 0021 may be of an integral structure, or the supporting plate 100 and one end of the arch ring 0021 are bonded by concrete, which is not limited in the embodiment of the present application. When the peripheral rock mass 001 of this underground cavern takes place to break, the rock mass after the breakage can extrude supporting construction, leads to arch ring 0021 in this supporting construction to take place to deform, and the arch ring 0021 that takes place to deform can exert pressure to this backup pad 100, and backup pad 100 can be to the one side removal of being close to first elastic element 200. Optionally, the supporting plate 100 may be a steel plate, or may also be a reinforced concrete plate, or the supporting plate 100 may be another high-strength supporting plate, which is not limited in this embodiment of the present application.
In the present application, since the side of the supporting plate 100 away from the arch ring 0021 is in contact with the first elastic element 200, when the supporting plate 100 moves to the side close to the first elastic element 200, the first elastic element 200 is deformed in its elastic direction Y (for convenience of description, simply referred to as direction Y), so that the first elastic element 200 is compressed in the direction Y. For example, referring to fig. 2, the first elastic element 200 is a pie-shaped airbag, and when the pie-shaped airbag is compressed along the direction Y, the area of the contact area between the compressed pie-shaped airbag and the supporting plate 100 increases, so the area of the contact area between the pie-shaped airbag and the supporting plate 100 needs to be smaller than the area of the plate surface of the supporting plate 100 close to the first elastic element 200. It should be noted that, the first elastic element 200 is a pie-shaped air bag only for an exemplary purpose, in practical applications, the first elastic element 200 may be a plurality of compression springs, or the first elastic element 200 may be another elastic structure having a certain elastic force, which is not limited in this embodiment of the present application.
Alternatively, the first end of the second elastic element 402 in the deformation determining assembly 400 may be fixedly connected with the inner wall of the box 401 in the deformation determining assembly 400 by screw fastening, and the second end may be fixedly connected with the first sliding block 403 by screw fastening. The pulley assembly 300 has a first end connected to a surface of the supporting plate 100 close to the first elastic member 200, and a second end fixedly connected to a side of the first slider 403 away from the second elastic member 402. After the supporting structure 002 deforms and applies pressure to the supporting plate 100, the supporting plate 100 moves along the direction Y, the supporting plate 100 can drive the first sliding block 403 to move along the elastic direction X (for convenience of description, simply referred to as the direction X) of the second elastic element 402 through the pulley assembly 300, so that the pointer 4042 connected to the first sliding block 403 moves, and the scale 404 of the deformation determining assembly 400 displays the deformation degree of the supporting structure. The elastic direction Y of the first elastic element 200 is perpendicular to the elastic direction X of the second elastic element 402.
It should be noted that the second elastic element 402 is an extension spring, and the material of the extension spring may be stainless steel, or the second elastic element 402 may be a return spring having a return effect, which is not limited in this embodiment of the present invention. After the deformation detecting device 000 is connected to the arch ring 0021 in the supporting structure 002, the first elastic element 200 is always in a compressed state, and the second elastic element 402 is always in a stretched state. The second elastic element 402 may be stretched by the pulley assembly 300 when the first elastic element 200 is compressed by the pressure of the deformed supporting structure 002. During this process, the forces experienced at the ends of the sheave assembly 300 are always in equilibrium.
It should be noted that the dial 4041 of the scale 404 may be provided with a plurality of sequentially arranged scale marks, and it is necessary to ensure that the pointer 4042 of the scale 404 points to one of the outermost scale marks (for example, the leftmost scale mark) of the plurality of scale marks immediately after the deformation detection device 000 is mounted on the supporting structure 002, and that the pointer 4042 points to another outermost scale mark of the plurality of scale marks (for example, the rightmost scale mark) after the deformation of the supporting structure 002 occurs.
Alternatively, referring to fig. 3 and 4, the scale 4041 is a circular scale, and the deformation determining assembly 400 further includes: a gear 405 and a rack 406 located within the housing 401.
Wherein, the gear 405 is movably connected with the inner wall of the box 401 and is fixedly connected with one end of the pointer 4042; the rack 406 is engaged with the gear 405 and is tightly connected to the first slider 403, and the length direction of the rack 406 is the same as the moving direction of the first slider 403, i.e. the length direction of the rack 406 is parallel to the direction X.
In this application, the deformation determining assembly 400 further includes a gear shaft 407, and the gear 405 may be sleeved on the gear shaft 407 and fixedly connected to the gear shaft 407. For example, the gear 405 may be fixedly connected to the gear shaft 407 by a key connection or by welding. The inner wall of the case 401 is provided with two connection holes (not shown) matching the shapes of both ends of the gear shaft 407. Two ends of the gear shaft 407 are movably connected with the two connecting holes respectively, and the axis of the gear shaft 407 coincides with the axis of the connecting holes. For example, each end of the gear shaft 407 may be movably coupled to a corresponding coupling hole through a bearing. The gear shaft 407 has one end located outside the case 401, and one end of the gear shaft 407 located outside the case 401 may be fixedly connected to one end of the pointer 4042 in the scale 402 by welding.
Thus, when the supporting plate 10 drives the first slider 403 to move along the direction X through the pulley assembly 300, the first slider 403 drives the rack 406 fixedly connected to the first slider 403 to move along the direction X, the rack 406 drives the gear 405 engaged with the rack 406 to rotate, and further drives the gear shaft 407 fixedly connected to the gear 405 to rotate, so that the pointer 4042 fixedly connected to the gear shaft 407 rotates, and the rotated pointer 4042 can be matched with the circular dial, so that the dial 404 displays the deformation degree of the supporting structure.
It should be noted that the dial 4041 may also be an elongated dial, the pointer 4042 is directly and fixedly connected to the first slider 403, when the first slider 403 moves along the direction X, the first slider 403 drives the pointer 4042 to move along the direction X, so that the pointer 4042 is matched with the elongated dial, so that the dial 404 displays the deformation degree of the supporting structure, which is not limited in the embodiment of the present application. In addition, the connection manner between the box 401 and the gear shaft 407, the connection manner between the gear shaft 407 and the gear 405, and the connection manner between the gear shaft 407 and the pointer 4042 are only exemplary, and in practical applications, the connection manner may be adjusted according to practical situations, which is not limited in the embodiments of the present application.

The alarm trigger 408 may be a light touch switch, and the alarm trigger 408 is configured to control the alarm indicator 409 to be turned on after the rack 406 applies pressure to the alarm trigger 408, so as to remind a worker that the support structure may be broken, thereby ensuring safety of the worker during construction work in the underground cavern.
For example, referring to fig. 4, the housing 401 has: the sliding groove comprises a cavity B for accommodating the gear 405 and the rack 406, an accommodating groove C and a first sliding groove D which are communicated with the cavity B, and a second sliding groove E which is separated from the cavity B, wherein the length directions of the first sliding groove D and the second sliding groove E are the same, and the accommodating groove C and the first sliding groove D are both positioned between the cavity B and the second sliding groove E. Referring to fig. 4 in conjunction with fig. 5, the deformation determining component 400 further includes: the wedge block 410 and the third elastic element 411 are located in the accommodating groove C, a first end of the third elastic element 411 is connected with the bottom surface of the wedge block 410, a second end of the third elastic element is connected with the bottom surface of the accommodating groove C, the inclined surface of the wedge block 410 faces the first end of the rack 406, and the alarm trigger 408 is located between the bottom surface of the wedge block 410 and the bottom surface of the accommodating groove C. For example, the first end of the third elastic element 411 is fixedly connected to the bottom surface of the wedge block 410 by screw fastening, and the second end is fixedly connected to the bottom surface of the receiving groove C by screw fastening. The alarm trigger 408 is fixed on the bottom surface of the receiving groove C, and when the first end of the rack 406 contacts the inclined surface of the wedge block 410, the wedge block 410 moves close to the bottom surface of the receiving groove C along the direction Y, so that the bottom surface of the wedge block 410 contacts the alarm trigger 408, and the alarm trigger 408 controls the alarm indicator 409 to be turned on.
In this application, the number of the third elastic elements 411 is plural, and the plural third elastic elements 411 uniformly surround the periphery of the alarm trigger 408, and the plural third elastic elements 411 may be compression springs.

Thus, after the rack 406 moves to the side of the wedge block 410 close to the rack 406 along the direction X, the first end of the rack 406 can contact the inclined surface of the wedge block 410, and apply a pressure to the wedge block 410 along the direction X, so that the wedge block 410 moves close to the bottom surface of the receiving groove C along the direction Y, and the bottom surface of the wedge block 410 contacts and applies a pressure to the alarm trigger 408.
