[0030] Example

[0031] See also Figure 1 The present embodiment provides a rock softening degree detection device 10, which is used to detect the rock softening degree. It can accurately detect the rock softening degree, is easy to operate, and can be completed by one worker.

[0032] In the prior art, there are many devices or methods for measuring parameters of soil before and after it softens when exposed to water, but there is no device for measuring the degree of softening of rock when exposed to water.

[0033] Please refer to Figure 1 and Figure 2 The rock softening degree detection device 10 includes a fixed bracket 100, a driving structure 200 and a probe assembly 300, wherein the fixed bracket 100 is used to be connected to the rock to provide support for measuring the rock softening degree, so as to facilitate the operation of the operator. The driving structure 200 is movably connected to the fixed bracket 100, and the driving structure 200 is connected to the probe assembly 300. The driving structure 200 can move relative to the fixed bracket 100, and drive the probe assembly 300 to move toward the rock, and the probe assembly 300 can be inserted into the rock under the drive of the driving structure 200. In this embodiment, the force applied by the driving structure 200 to the probe assembly 300 is the same in multiple measurements, and the softening degree of the rock is judged by the depth of the probe assembly 300 inserted into the rock.

[0034] The driving structure 200 includes a driving member 210, a distance device 220 and an elastic member 230, wherein the driving member 210 is movably connected to the fixed bracket 100, and the driving member 210 can move relative to the fixed bracket 100. In addition, the driving member 210 is connected to the probe assembly 300 through the elastic member 230, the driving member 210 can move relative to the fixed bracket 100 and cause the elastic member 230 to deform, and the elastic force of the elastic member 230 to restore the deformation drives the probe assembly 300 to move toward the rock, and the elastic member 230 can insert the probe assembly 300 into the rock through the elastic force.

[0035] When the probe assembly 300 is inserted into the rock and the reaction force of the rock on the probe assembly 300 is equal to the deformation of the elastic member 230 and the force on the probe assembly 300, that is, when the probe assembly 300 is inserted into the rock to a certain depth and remains stable, the deformation amount of the elastic member 230 is determined. In multiple measurements, it is only necessary to ensure that the deformation amount of the elastic member 230 is the same when the probe assembly 300 is stable, and the softening degree of the rock is judged by the depth of the probe assembly 300 inserted into the rock.

[0036] In this embodiment, the deformation amount of the elastic member 230 when the probe assembly 300 is stable is measured by the distance device 220. Since the elastic member 230 is arranged between the driving member 210 and the probe assembly 300, the displacement distance of the driving member 210 relative to the probe assembly 300 is the deformation amount of the elastic member 230. Among them, the distance device 220 is connected between the driving member 210 and the probe assembly 300 to measure the displacement amount of the driving member 210 relative to the probe assembly 300, that is, the deformation amount of the elastic member 230 can be measured. Determining the deformation amount of the elastic member 230 by the distance device 220 is convenient for ensuring that the deformation amount of the elastic member 230 is the same when measuring multiple times, and it is convenient to record the deformation amount of the elastic member 230.

[0037] It should be noted that, in this embodiment, the driving member 210 moves relative to the fixed bracket 100 to compress the elastic member 230 and cause the elastic member 230 to deform. The deformed elastic member 230 pushes the probe assembly 300 to move by the thrust generated by the restored deformation.

[0038] The driving member 210 is provided with a first through hole 211, which passes through the driving member 210, and the driving member 210 is arranged toward the probe assembly 300. In addition, the distance device 220 includes a ruler 221, one end of which is against the probe assembly 300, and the ruler 221 can move following the movement of the probe assembly 300. In addition, the other end of the ruler 221 passes through the first through hole 211 and extends out of the first through hole 211, that is, the end of the ruler 221 away from the probe assembly 300 is exposed to the driving member 210, so that the user can read and confirm the movement of the driving member 210 relative to the ruler 221 by extending the part of the driving member 210. Among them, the ruler 221 moves with the probe assembly 300, so the moving distance of the driving member 210 relative to the ruler 221 is the moving distance of the driving member 210 relative to the probe assembly 300. That is, in this embodiment, the user can know the deformation amount of the elastic member 230 by the distance that the ruler rod 221 moves relative to the driving member 210. In addition, in this embodiment, the ruler rod 221 has a scale to facilitate the user to measure the distance.

[0039] Further, in the present embodiment, the driving structure 200 further comprises a connecting plate 240, one side of the connecting plate 240 is against the probe assembly 300, one end of the ruler rod 221 close to the probe assembly 300 is fixedly connected to the side of the connecting plate 240 away from the probe assembly 300, and the elastic member 230 is against the side of the connecting plate 240 away from the probe assembly 300, and the elastic member 230 drives the probe assembly 300 to move by pushing the connecting plate 240. By setting the connecting plate 240, the elastic member 230 can ensure that the probe assembly 300 has a relatively stable moving direction when pushing the probe assembly 300 to move. In addition, the ruler rod 221 can be made not to produce a radial offset relative to the ruler rod 221 when moving, thereby ensuring the accuracy of the measurement of the ruler rod 221.

[0040] In this embodiment, the elastic member 230 is a spring, which is sleeved on the ruler rod 221 , and two ends of the spring are respectively abutted against the driving member 210 and the connecting plate 240 .

[0041] In addition, a plurality of hand-held portions 212 are provided at one end of the driving member 210 away from the elastic member 230, and the plurality of hand-held portions 212 are arranged at intervals along the circumferential direction of the driving member 210. In this embodiment, there are four hand-held portions 212, and the four hand-held portions 212 form a cross shape on the driving member 210. The cross-shaped hand-held portions 212 make it easier for the user to apply force when driving the driving member 210.

[0042] The probe assembly 300 includes a sleeve 310 and a probe 320. The sleeve 310 is fixedly connected to the fixing bracket 100, and a second through hole 311 is opened inside the sleeve 310. The probe 320 passes through the second through hole 311 and is connected to the elastic member 230, and the probe 320 can move along the second through hole 311. When the driving member 210 compresses the elastic member 230, the elastic member 230 pushes the connecting plate 240 through the restoring force, so that the probe 320 is pushed to move along the second through hole 311 through the movement of the connecting plate 240, and the probe 320 is inserted into the rock.

[0043] In this embodiment, a thread is disposed on the outer side of the sleeve 310 , and the sleeve 310 and the fixing bracket 100 are connected by threaded cooperation to ensure the stability of the sleeve 310 .

[0044] The probe 320 includes a sliding portion 321 and an inserting portion 322. The sliding portion 321 is slidably connected to the sleeve 310 through the second through hole 311. One end of the sliding portion 321 is connected to the elastic member 230. The inserting portion 322 is fixedly connected to the end of the sliding portion 321 away from the elastic member 230, and the end of the inserting portion 322 away from the sliding portion 321 is tapered. In this embodiment, the outer wall of the sliding portion 321 is attached to the inner circumferential wall of the second through hole 311, and the sliding portion 321 can slide along the second through hole 311. The cross-sectional area of ​​the inserting portion 322 is smaller than the cross-sectional area of ​​the sliding portion 321, and the extension direction of the inserting portion 322 is the same as that of the sliding portion 321, so that when the sliding portion 321 is pushed by the elastic member 230, the force of the inserting portion 322 to insert into the rock can be extended along the axial direction of the inserting portion 322, so that the inserting portion 322 is easy to be inserted into the rock. In this embodiment, the inner diameter of the second through hole 311 is larger than the area of ​​the connecting plate 240 , so that the connecting plate 240 can slide in the second through hole 311 and drive the probe 320 to slide under the drive of the driving member 210 .

[0045] In addition, in this embodiment, the tapered portion of the inserting portion 322 away from the sliding portion 321 is a cone, and the head of the cone is 30°. It should be understood that in other embodiments, the end of the inserting portion 322 away from the sliding portion 321 may also be a pyramid or a spiral cone.

[0046] Furthermore, a scale is provided on the insertion portion 322 so that the user can know the depth of the insertion portion 322 into the rock.

[0047] Please refer to Figure 1 , Figure 3 and Figure 4 The fixing bracket 100 includes a mounting portion 110, a bearing portion 120 and a plurality of connecting rods 130, wherein the mounting portion 110 is connected to the bearing portion 120 via the plurality of connecting rods 130. The bearing portion 120 is used to be connected to the rock and bear the weight of the rock softening degree detection device 10, and a mounting hole 111 is provided on the mounting portion 110. The driving structure 200 is connected to the mounting portion 110 via the mounting hole 111, and the driving structure 200 can move relative to the mounting portion 110 to drive the probe assembly 300 to move toward the rock.

[0048] In this embodiment, the driving member 210 is connected to the mounting portion 110 through the mounting hole 111, and the driving member 210 can move relative to the mounting portion 110 to drive the probe 320 to move. In addition, in this embodiment, the mounting hole 111 is provided with an internal thread, and the outer side of the driving member 210 is provided with an external thread that matches the internal thread. The driving member 210 is threadedly connected to the mounting hole 111, that is, the user holds the handheld portion 212 and rotates the driving member 210 so that the driving member 210 follows the thread and moves along the mounting hole 111 to drive the probe 320 to move toward the rock. Among them, the threaded connection makes the moving distance of the driving member 210 highly adjustable, and can achieve small distance adjustment, thereby improving the detection accuracy.

[0049] In this embodiment, the mounting hole 111 includes a first mounting section 1111 and a second mounting section 1112. The first mounting section 1111 and the second mounting section 1112 together constitute the mounting hole 111, and the first mounting section 1111 is connected to the second mounting section 1112. The first mounting section 1111 is connected to the driving structure 200, and the driving structure 200 can move along the first mounting section 1111. The second mounting section 1112 is connected to the probe assembly 300. The first mounting section 1111 and the second mounting section 1112 are both provided with threads corresponding to the driving structure 200 and the probe assembly 300, respectively.

[0050] Furthermore, in this embodiment, the aperture of the first mounting section 1111 is smaller than the aperture of the second mounting section 1112. When the sleeve 310 is connected to the mounting portion 110 through the second mounting section 1112, the aperture of the second through hole 311 is similar to the aperture of the first mounting section 1111, thereby avoiding the displacement of the driving member 210 due to the large gap inside the first mounting section 1111, and ensuring the measurement accuracy of the rock softening degree detection device 10.

[0051] It should be understood that the mounting hole 111 may not be provided with threads, and the user may directly apply pressure along the mounting hole 111 to enable the driving member 210 to drive the probe 320 to be inserted into the rock.

[0052] Further, in this embodiment, a plurality of threaded holes 112 are provided on the mounting portion 110, and the plurality of threaded holes 112 correspond to the plurality of connecting rods 130 respectively, and the plurality of connecting rods 130 are fixedly connected to the mounting portion 110 through the plurality of threaded holes 112. The plurality of threaded holes 112 all penetrate the mounting portion 110, so that the connecting rod 130 passes through the threaded holes 112 and is connected to the mounting portion 110, thereby realizing the function of adjustable distance between the mounting portion 110 and the bearing portion 120. One end of the connecting rod 130 is provided with a thread matching the threaded hole 112, so that the connecting rod 130 can be connected to the mounting portion 110, and the other end of the connecting rod 130 is embedded in the bearing portion 120. In addition, a third through hole 121 is provided in the middle of the bearing portion 120, and the probe assembly 300 can be inserted into the rock through the third through hole 121.

[0053] In this embodiment, the mounting portion 110 and the bearing portion 120 are both triangular, and there are three connecting rods 130, which are respectively connected to three corners of the mounting portion 110 and the bearing portion 120. Moreover, the third through hole 121 is also triangular, so that the bearing portion 120 is triangular frame-shaped.

[0054] The bearing part 120 is also provided with a fixing connecting member 400, which includes two long screws 410 and a plurality of screw holes 420. The plurality of screw holes 420 are respectively opened on the bearing part 120, and the two long screws 410 are respectively provided on the bearing part 120 through the two screw holes 420. Part of the screw holes 420 are used to connect with the expansion bolts on the rock, and then the bearing part 120 can be fixedly connected to the rock by tightening the two long screws 410, so as to ensure the stability of the rock softening degree detection device 10. The number of screw holes 420 is greater than the number of long screws 410, so that part of the screw holes 420 can be used to cooperate with the expansion bolts.

[0055] It should be understood that in other embodiments, the fixed connection member 400 may be omitted, and the bearing portion 120 may be simply placed on the rock.

[0056] When measuring the rock softening degree, the rock softening degree detection device 10 provided in this embodiment first fixes the bearing part 120 on the rock, and drives the driving member 210 to rotate by rotating the hand-held part 212. The driving member 210 moves along the mounting hole 111 during rotation and compresses the elastic member 230. The elastic member 230 pushes the connecting plate 240 through the restoring force to push the probe 320 to slide along the second through hole 311 and insert into the rock. When the probe 320 is stable, the displacement distance of the driving member 210 relative to the ruler 221 is read to determine the deformation amount of the elastic member 230, and the scale on the insertion part 322 is read to determine the insertion depth of the insertion part 322. The rock softening degree detection device 10 is changed to another position, and the above steps are continued to be repeated. It is only necessary to ensure that the displacement of the driving member 210 relative to the ruler 221 is the value read last time when rotating the driving member 210. The insertion depth of the insertion part 322 after multiple measurements is compared to determine the softening degree of the rock.

[0057] The rock softening degree detection device 10 provided in this embodiment moves the driving member 210 movably arranged on the fixed bracket 100 relative to the fixed bracket 100 and deforms the elastic member 230 connected between the driving member 210 and the probe assembly 300, and the deformed elastic member 230 pushes the probe assembly 300 toward the rock through the force of restoring the deformation, and the driving member 210 can drive the probe assembly 300 to insert into the rock through the elastic member 230. In addition, by arranging a distance device 220 between the driving member 210 and the probe assembly 300, and measuring the deformation amount of the elastic member 230 through the distance device 220, the distance device 220 ensures that the deformation amount of the elastic member 230 is the same each time, so as to measure the depth to which the probe assembly 300 can be inserted into the rock under the push of the elastic member 230 under the same thrust, so as to judge the softening degree of the rock, and the rock softening degree detection device 10 is small in size, easy to carry, convenient and flexible, simple to assemble, and can be operated by one person.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
