Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock mechanics testing, in particular to a rapid positioning and mounting device for a deformation sensor. BACKGROUND

[0002] In the field of indoor rock mechanics testing devices, the study of rock deformation characteristics has always been in a key position. The deformation characteristics of rock, as an important parameter indispensable for in-depth analysis of rock mechanics properties, the accuracy of its measurement is directly related to the depth and breadth of understanding of rock mechanics behavior. In actual scientific research and testing work, the acquisition of rock strain mainly depends on the accurate determination of deformation sensors, and a suitable and efficient mounting device is particularly important for deformation sensors to perform their best performance.

[0003] At present, when performing rock mechanics tests, the installation of deformation sensors only relies on two positioning rods for installation. This installation device has several shortcomings:

[0004] 1. The lower ring clamp must be supported by other objects due to its structural limitations during installation. However, this method not only makes it difficult to ensure that the clamp is in an ideal horizontal state, but also makes the entire installation process extremely complex. In actual operation scenarios, it is often difficult for a single person to complete the installation independently, and even two people need to work closely together, which not only consumes a lot of manpower, but also reduces the efficiency of the test; 2. The installation process of the upper and lower double-ring clamps is usually adjusted by the operator's naked eye, but this method based on visual observation has a lot of subjectivity and error, and cannot guarantee the centering of the sample and the level of the ring clamp. The distance between the positioning rod adjustment holes is too large, and the distance between the double-ring clamps is difficult to fine-tune according to the actual situation of the sample, which will affect the accuracy of the test data in the subsequent test process, and thus greatly reduce the accuracy of the test results.

[0005] The complexity of this installation and the inflexibility of the adjustment seriously limit the applicability and accuracy of the test.

[0046] In the above manner, the centering position of the sample 7 in the clamp can be accurately ensured by the detection of the positioning device and the cooperation and adjustment of the upper and lower fixing devices, the installation error is greatly reduced, and the accuracy of the test data is effectively improved; at the same time, the setting of the base 1 realizes the self-stability of the structure, and a single person can easily complete the installation without the help of other objects, which not only saves the labor cost, but also greatly shortens the installation time and significantly improves the test efficiency. In addition, the operation process of the device is simple and easy to understand, even for personnel who have never contacted it before, they can quickly get started, and the stability and reliability of the test are improved.

[0047] Further, in the embodiment of the application, the base 1 is a circular ring.

[0048] In this way, the base 1 is designed as a circular ring, and a position for fixing the sample 7 is arranged in the middle of the circular ring.

[0049] Further, in the embodiment of the present application, the first support plate 21 is in the shape of an inverted "L", and a first positioning column 211 is vertically arranged on the upper part of the first support plate 21. The first positioning columns 211 on the two first support plates 21 on the two sides of the base 1 are symmetrically arranged about the central axis of the base 1.

[0050] In this way, the first support plate 21 in the shape of an inverted "L" can make the lower clamp 22 stably placed on the first support plate 21, and the first positioning columns 211 vertically arranged symmetrically about the central axis of the base 1 can make the lower clamp 22 located at the center of the base 1.

[0051] Further, in the embodiment of the present application, the fixing frame 31 is in the shape of a "N" horizontally arranged, and the second support plate 32 is in the shape of a "U" horizontally arranged at the two ends of the fixing frame 31. The second support plate 32 is vertically arranged on the upper part of the second support plate 32, and the second positioning column 321 is vertically arranged on the upper part of the second support plate 32. The second positioning columns 321 on the two second support plates 32 at the two ends of the fixing frame 31 are symmetrically arranged about the central axis of the base 1.

[0052] In this way, the second support plate 32 horizontally arranged at the two ends of the fixing frame 31 can make the upper clamp 34 stably placed on the second support plate 32, and the second positioning columns 321 vertically arranged symmetrically about the central axis of the base 1 can make the upper clamp 34 located at the center of the base 1.

[0053] In some embodiments of the present application, the second support plate 32 can be directly fixed on the fixing frame 31. When the lower clamp 22 needs to be installed, the position of the lifting device can be adjusted to make the second support plate 32 located above the sample 7, so as to avoid the influence of the second support plate 32 on the installation of the lower clamp 22. In other embodiments of the present application, a rotating shaft 33 can be arranged at the end of the fixing frame 31, and the second support plate 32 is rotatably connected to the fixing frame 31 through the rotating shaft 33. The second support plate 32 can rotate about the rotating shaft 33 from an avoiding state to a supporting state. When the second support plate 32 is in the avoiding state, the inner cavity of the fixing frame 31 has a cavity for the lower clamp 22 to completely pass through. When the second support plate 32 is in the supporting state, the second positioning columns 321 in the two second support plates 32 are symmetrically arranged about the central axis of the base 1. In this way, the second support plate 32 can be rotated to ensure the smooth installation of the lower clamp 22 without adjusting the height of the lifting device.

[0054] In the above embodiment, when the second support plate 32 is rotatably connected to the fixed frame 31 through the rotating shaft 33, the angle of rotation of the second support plate 32 about the rotating shaft 33 and the position of the second support plate 32 in different states can be adjusted according to actual needs, as long as the lower clamp 22 can pass in the avoiding state and the two second positioning columns 321 are symmetrical about the central axis of the base 1 in the supporting state. For example, in an embodiment of the present application, the angle of rotation of the second support plate 32 about the rotating shaft 33 is preferably 90°. When the second support plate 32 is rotated 0° about the rotating shaft 33, the second support plate 32 is attached to the inner wall of the fixed frame 31, and at this time the second support plate 32 is in the avoiding state; when the second support plate 32 is rotated 90° about the rotating shaft 33 into the inner cavity of the fixed frame 31, the second support plate 32 and the second positioning columns 321 thereon are symmetrical about the central axis of the base 1, and at this time the second support plate 32 is in the supporting state.

[0055] Further, in the embodiment of the present application, the lower clamp 22 and the upper clamp 34 are the same circular ring; the lower clamp 22 is provided with a first positioning hole 222 for accommodating the first positioning column 211, and the upper clamp 34 is provided with a second positioning hole 342 for accommodating the second positioning column 321.

[0057] Further, in the embodiment of the present application, the side surface of the lower clamp 22 is symmetrically provided with a first screw hole penetrating through the lower clamp 22 and a first fastening screw 221 threadedly connected with the first screw hole, and the side surface of the upper clamp 34 is symmetrically provided with a second screw hole penetrating through the upper clamp 34 and a second fastening screw 341 threadedly connected with the second screw hole; the first screw hole and the second screw hole are not less than three respectively.

[0058] In the above manner, by providing the first screw hole penetrating through the lower clamp 22 and the first fastening screw 221 threadedly connected therewith, and providing the second screw hole penetrating through the upper clamp 34 and the second fastening screw 341 threadedly connected therewith, when the light ray emitting device 5 projects a “cross” mark with scales located on the central axis of the clamp, the fastening distance of the fastening screw can be adjusted according to the scales on the mark, and the position of the test sample 7 can be accurately adjusted, so that the test sample 7 is located at the central position of the clamp.

[0059] Further, in the embodiment of the present application, the upper clamp 34 is provided with an extensometer 6, and the lower clamp 22 is provided with a detection hole connected with the extensometer 6.

[0060] In the above manner, by providing the detection hole connected with the extensometer 6 on the lower clamp 22, the extensometer 6 can be connected with the upper and lower clamps, the distance displacement change of two points or two lines of the sample 7 can be measured, and the deformation data can be obtained.

[0061] Further, in the embodiment of the present application, the fixing sleeve 42 is fixed on the stand column 41 through a positioning bolt 421.

[0062] In the above manner, the fixing sleeve 42 can be sleeved on the stand column 41 and connected with the fixing frame 31, so that the upper fixing device can move up and down along the stand column 41, and the upper fixing device can be fixed at a required height through the positioning bolt 421.

[0063] Further, in the embodiment of the present application, the positioning light emitting device 5 is located on the vertical central axis of the base 1.

[0064] In the above manner, the positioning light emitting device 5 can project a "cross" mark with scales on the central axis of the clamp, so as to check whether the sample 7 is located at the center of the upper and lower clamps.

[0065] The installation process of the quick positioning and installation device for the deformation sensor provided in the present application is as follows:

Adjust the height of the fixing sleeve 42 on the stand 41 according to the height of the sample 7, so that the height of the fixing sleeve 42 is at the position of the lower pressing head 82, then tighten the positioning bolt 421, so that the second support plate 32 is in the supporting state, align the second positioning hole 342 of the upper clamp 34 with the second positioning column 321 on the second support plate 32, and place the upper clamp 34 on the second support plate 32. Turn on the positioning light emitting device 5, tighten the first fastening screw 221 and the second fastening screw 341, and adjust the first fastening screw 221 and the second fastening screw 341 according to the scale "cross" mark projected by the positioning light emitting device 5 on the center axis of the clamp, so that the center of the sample 7 coincides with the center of the "cross" mark, then test the sample 7 through the extensometer 6 connected with the upper and lower clamps.

[0067] If it is necessary to test the sample 7 of the same height later, the height of the lifting device can not be adjusted again, the old sample 7 and the corresponding clamp can be taken out by rotating the second support plate 32 inward by 90° to the avoiding state (as shown in Figure 3 After that, the new sample 7 and the lower clamp 22 can be installed, then the second support plate 32 is rotated to the supporting state, and the upper clamp 34 can be installed, so that the overall disassembly and installation process is more convenient.
