Description

Technical Field

[0001] The present invention relates to the technical field of deep mining devices for metal mines, and more particularly, to a test device for resisting instantaneous large-tonnage impact forces. Background Art

[0002] Rock burst refers to the phenomenon that rocks suddenly break and eject at high speed when subjected to stress. This phenomenon not only poses a threat to the safety of mining workers, but also causes equipment damage and production interruption. During the process of deep metal mine mining, roadway in rock burst hazard areas is usually protected by support equipment. However, in rock burst hazard areas, when a rock burst occurs, the support equipment is still prone to local damage caused by the rock burst. Therefore, it is necessary to develop a support equipment that can resist instantaneous large-tonnage impact forces. However, due to the danger of the rock burst process, at present, it is impossible to accurately measure the impact force and impact energy during the rock burst process, so it is impossible to accurately study the rock burst process, resulting in limitations in the technological update of the support equipment.

[0036] Referring to Figure 1 and Figure 4 As shown, the test device for resisting instantaneous large-tonnage impact forces involved in the embodiments of this application is provided with a preset direction x. The test device for resisting instantaneous large-tonnage impact forces includes: a test component 100 and a fixing component 200.

[0037] Specifically, the test component 100 includes a mounting member 110, a force sensor 120, and an acceleration sensor 130. Both the force sensor 120 and the acceleration sensor 130 are disposed on the mounting member 110; the fixing component 200 includes a hoisting member 210. The hoisting member 210 extends along the preset direction x and is fixedly connected to the mounting member 110, and the mounting member 110 is disposed at any position of the hoisting member 210 along the preset direction x.

[0038] It should be noted that the preset direction x is Figure 1 the direction indicated by x in

[0039] In the anti-instantaneous large-tonnage impact force test device of the present application, since the mounting member 110 is fixedly connected to the hoisting member 210, and the force measuring sensor 120 and the acceleration sensor 130 are both arranged on the mounting member 110, therefore, the test assembly 100 can be hoisted in the roadway of the rock burst hazard area through the hoisting member 210. When a rock burst occurs, the rock will strike the mounting member 110. At this time, the real-time impact force received by the mounting member 110 can be monitored through the force measuring sensor 120. At the same time, the real-time acceleration of the rock hitting the mounting member 110 during the rock burst process can be monitored through the acceleration sensor 130, so as to monitor the real-time impact energy received by the mounting member 110. In this way, the accurate study of the rock burst process can be realized, so as to technically update the protection ability of the support equipment.

[0040] Referring to Figure 4 As shown, the test assembly 100 further includes a force measurement data acquisition member 140 and a first electrical connection member 150. The force measurement data acquisition member 140 is connected to the force measuring sensor 120 through the first electrical connection member 150.

[0041] In this embodiment, since the force measurement data acquisition member 140 is connected to the force measuring sensor 120 through the first electrical connection member 150, therefore, when a rock burst occurs, the real-time impact force monitored by the force measuring sensor 120 can be transmitted to the force measurement data acquisition member 140, so as to collect and analyze the real-time impact force received by the mounting member 110, thereby realizing the accurate study of the rock burst process.

[0042] Specifically, in this embodiment, the first electrical connection member 150 is a data cable. In addition, in other embodiments, the first electrical connection member 150 can also be other electrical connection members capable of realizing data transmission functions.

[0043] Continuing to refer to Figure 4 As shown, the test assembly 100 further includes an acceleration data acquisition member 160 and a second electrical connection member 170. The acceleration data acquisition member 160 is connected to the acceleration sensor 130 through the second electrical connection member 170.

[0044] In this embodiment, since the acceleration data acquisition member 160 is connected to the acceleration sensor 130 through the second electrical connection member 170, therefore, when a rock burst occurs, the acceleration monitored by the acceleration sensor 130 can be transmitted to the acceleration data acquisition member 160, so as to collect and analyze the real-time impact energy received by the mounting member 110.

[0045] Specifically, in this embodiment, the second electrical connection member 170 is a data cable. In addition, in other embodiments, the second electrical connection member 170 can also be other electrical connection members capable of realizing data transmission functions.

[0046] Referring to Figure 5 As shown, the mounting member 110 is provided with a mounting hole 111. The mounting hole 111 penetrates through both ends of the mounting member 110 along the preset direction x. The fixing assembly 200 further includes a fixing member 220. The fixing member 220 is fixedly connected to the hoisting member 210. Both the hoisting member 210 and the fixing member 220 are inserted through the mounting hole 111, and the fixing member 220 abuts against the hole wall of the mounting hole 111.

[0047] In this embodiment, the hoisting member 210 can be inserted through the mounting hole 111 along the preset direction x to connect the hoisting member 210 and the mounting member 110. At the same time, since the fixing member 220 is fixedly connected to the hoisting member 210 and the fixing member 220 abuts against the hole wall of the mounting hole 111, the fixing member 220 can be prevented from moving relative to the mounting member 110 along the preset direction x, so as to fix the hoisting member 210 and the mounting member 110 through the fixing member 220.

[0048] Continuing to refer to Figure 5 As shown, the mounting hole 111 includes a first hole section 1111 and a second hole section 1112. The second hole section 1112 is provided at one end of the first hole section 1111 along the preset direction x and is communicated with the first hole section 1111. Both the first hole section 1111 and the second hole section 1112 extend along the preset direction x. The hoisting member 210 is inserted through both the first hole section 1111 and the second hole section 1112 at the same time. The fixing member 220 is inserted through the second hole section 1112 and abuts against the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x.

[0049] In this embodiment, since the second hole section 1112 is provided at one end of the first hole section 1111 along the preset direction x and is communicated with the first hole section 1111, and both the first hole section 1111 and the second hole section 1112 extend along the preset direction x, the hoisting member 210 can be inserted through both the first hole section 1111 and the second hole section 1112 at the same time to mount the mounting member 110 onto the hoisting member 210. Also, since the fixing member 220 is inserted through the second hole section 1112 and abuts against the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x, the abutment of the fixing member 220 against the hole wall of the second hole section 1112 can prevent the hoisting member 210 from moving relative to the mounting hole 111 along the preset direction x, so as to fix the mounting member 110 and the hoisting member 210.

[0050] Referring to Figure 2 As shown, the first hole section 1111 and the second hole section 1112 are coaxially arranged. The aperture of the first hole section 1111 is D1, the aperture of the second hole section 1112 is D2, and the diameter of the fixing member 220 is D3, satisfying: D1 < D3 < D2.

[0051] In this embodiment, since the first hole section 1111 and the second hole section 1112 are coaxially arranged, the lifting member 210 can be inserted into both the first hole section 1111 and the second hole section 1112 at the same time, and there will be no stress concentration area on the lifting member 210, so as to avoid affecting the strength of the lifting member 210 by the mounting member 110. Also, since the aperture D1 of the first hole section 1111, the aperture D2 of the second hole section 1112, and the diameter D3 of the fixing member 220 satisfy: D1 < D3 < D2, the fixing member 220 can be inserted into the second hole section 1112, and the fixing member 220 can be made to abut against the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x, so as to prevent the fixing member 220 from moving relative to the mounting member 110 along the preset direction x, thereby fixing the lifting member 210 and the mounting member 110 through the fixing member 220.

[0052] Specifically, in this embodiment, referring to Figure 5 As shown, in the preset direction x, the aperture of the end of the first hole section 1111 far from the second hole section 1112 gradually increases in the direction away from the second hole section 1112, so as to form a chamfer 1113 facing outside the first hole section 1111 at the end of the first hole section 1111 far from the second hole section 1112. When the lifting member 210 is inserted into the mounting hole 111, since the aperture of the second hole section 1112 is larger than that of the first hole section 1111, the friction between the end of the second hole section 1112 far from the first hole section 1111 along the preset direction x and the lifting member 210 is reduced, and the wear of the mounting member 110 is reduced. And at the end of the first hole section 1111 along the preset direction x away from the second hole section 1112, the friction between the mounting member 110 and the lifting member 210 can be reduced through the chamfer 1113, and the wear of the mounting member 110 is reduced.

[0053] Specifically, in this embodiment, referring to Figure 5 As shown, in the preset direction x, the total length of the mounting hole 111 is L1, and the length of the second hole section 1112 is L2, satisfying: 1 / 3 ≤ L2 / L1 ≤ 2 / 3.

[0054] More specifically, in this embodiment, L2 / L1 can take values such as 1 / 3, 1 / 2, 2 / 3, etc.

[0055] In this embodiment, when the total length L1 of the installation hole 111 and the length L2 of the second hole section 1112 satisfy: L2 / L1 < 1 / 3, the length of the second hole section 1112 will be too short. Thus, the connection stability between the fixing member 220 and the hole wall of the second hole section 1112 will be reduced, and further the fixing effect of the fixing member 220 on the hoisting member 210 will be reduced. When the total length L1 of the installation hole 111 and the length L2 of the second hole section 1112 satisfy: L2 / L1 > 2 / 3, the length of the second hole section 1112 will be too long, that is, the length of the first hole section 1111 will be too short. Thus, the supporting effect of the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x on the fixing member 220 will be reduced, and the fixing effect of the fixing member 220 on the hoisting member 210 will be reduced. When the total length L1 of the installation hole 111 and the length L2 of the second hole section 1112 satisfy: 1 / 3 ≤ L2 / L1 ≤ 2 / 3, the connection stability between the fixing member 220 and the installation member 110 can be improved, so as to improve the fixing effect of the fixing member 220 on the hoisting member 210.

[0056] Specifically, in this embodiment, the hoisting member 210 is a cable bolt. One end of the cable bolt is fixed on the surrounding rock of the roadway. The installation member 110 is arranged at any position of the cable bolt along the preset direction x. The fixing member 220 is an anchor. The fixing of the fixing assembly on the installation member 110 is realized through the fixed connection between the anchor and the cable bolt. When the cable bolt is fixedly connected to the anchor, the cable bolt passes through the anchor, and the fixing between the cable bolt and the anchor is realized by the clamping of the anchor on the cable bolt in the second hole section 1112. In addition, in other embodiments, the hoisting member 210 can also be other structures capable of suspending and hoisting the installation member 110, and the fixing member 220 can also be other structures capable of being fixedly connected to the hoisting member 210. For example, the hoisting member 210 is a steel bar with an external thread on the surface, and the fixing member 220 is a sleeve structure with an internal thread. The fixing of the installation member 110 is realized through the threaded connection between the hoisting member 210 and the fixing member 220.

[0057] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in, the test device for resisting instantaneous large-tonnage impact force includes a plurality of fixing assemblies 200. A plurality of installation holes 111 are formed in the installation member 110. The plurality of installation holes 111 are arranged at intervals. Each fixing assembly 200 passes through one installation hole 111. The test assembly 100 further includes a plurality of leveling members 180. Each leveling member 180 passes through one second hole section 1112 and is sleeved outside the fixing member 220. The leveling member 180 can move relative to the fixing member 220 along the preset direction x, and the leveling member 180 abuts against the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x.

[0058] In this embodiment, since each fixing component 200 is passed through a mounting hole 111, the mounting member 110 can be connected to a plurality of fixing components 200 at the same time, so as to improve the fixing effect of the fixing component 200 on the test component 100. Since the leveling member 180 is passed through the second hole section 1112 and sleeved outside the fixing member 220, and the leveling member 180 can move relative to the fixing member 220 along the preset direction x and abuts against the hole wall of the second hole section 1112 close to the first hole section 1111 along the preset direction x, when the mounting member 110 is connected to a plurality of fixing components 200 at the same time, the leveling member 180 can move relative to the fixing member 220 along the preset direction x, so as to push the mounting member 110 by the movement of a plurality of leveling members 180, so that the mounting member 110 is connected to the same position of each lifting member 210 along the preset direction x, thereby improving the force uniformity of each part of the mounting member 110, and reducing the monitoring variables of the force sensor 120 and the acceleration sensor 130 accordingly.

[0059] Specifically, in this embodiment, a plurality of mounting holes 111 are arranged at equal intervals around the central axis of the mounting member 110 along the preset direction x, so as to improve the monitoring accuracy of the force sensor 120 and the acceleration sensor 130.

[0060] More specifically, in this embodiment, the mounting member 110 is provided with three mounting holes 111, and the three mounting holes 111 are arranged at equal intervals around the central axis of the mounting member 110 along the preset direction x, that is, the angle between any two adjacent mounting holes 111 is 60°, and each mounting hole 111 is passed through by a fixing component 200.

[0061] Refer to Figure 3 and Figure 6 As shown, an external thread 221 extending spirally around the preset direction x is provided on the outer surface of the fixing member 220, and an internal thread 181 is provided on the leveling member 180, and the fixing member 220 is threadedly connected to the leveling member 180.

[0062] In this embodiment, since an external thread 221 extending spirally around the preset direction x is provided on the outer surface of the fixing member 220, and the fixing member 220 is threadedly connected to the leveling member 180, the leveling member 180 can move relative to the fixing member 220 along the preset direction x, so as to realize the pushing of the leveling member 180 against the mounting member 110. At the same time, after the mounting member 110 is leveled, the leveling member 180 can be locked through the threaded connection between the fixing member 220 and the leveling member 180, so as to prevent the leveling member 180 from moving after the mounting member 110 is leveled, and improve the structural stability of the mounting member 110 after leveling.

[0063] Specifically, in this embodiment, refer to Figure 3As shown, in the preset direction x, one end of the leveling member 180 away from the first hole section 1111 protrudes at least partially outside the mounting member 110, and the measuring surface of the end of the leveling member 180 away from the first hole section 1111 has a wrench plane 182 symmetrically arranged with respect to the preset direction x, so as to facilitate the wrench to abut against the wrench plane 182, thereby realizing the screwing of the leveling member 180.

[0064] Referring to Figure 4 and Figure 5 As shown, the mounting member 110 has a reference plane 112, the reference plane 112 is located at one end of the mounting member 110 along the preset direction x, the test assembly 100 further includes a leveling detection member 190, the leveling detection member 190 is arranged on the mounting member 110 and is arranged parallel to the reference plane 112, and the leveling detection member 190 is used to detect the perpendicularity of the reference plane 112 to the preset direction x.

[0065] In this embodiment, after the mounting member 110 is leveled by the leveling member 180, the reference plane 112 of the mounting member 110 is perpendicular to the preset direction x. In this process, the perpendicularity of the reference plane 112 to the preset direction x can be detected by the leveling detection member 190, so as to determine whether the mounting member 110 is leveled.

[0066] Referring to Figure 7 As shown, the leveling detection member 190 is provided with a detection bubble 191, and the detection bubble 191 is movably located at various positions of the leveling detection member 190. When the reference plane 112 is perpendicular to the preset direction x, the detection bubble 191 is located at the central position of the leveling detection member 190.

[0067] In this embodiment, during the leveling process of the mounting member 110, the perpendicularity of the reference plane 112 to the preset direction x can be judged by observing the position of the detection bubble 191 in the leveling detection member 190. Since it is arranged parallel to the reference plane 112, when the detection bubble 191 is located at the central position of the leveling detection member 190, it means that the detection bubble 191 only receives the force along the preset direction x. Thus, it means that the reference plane 112 is perpendicular to the preset direction x, that is, it means that the mounting member 110 has been leveled.

[0068] Specifically, in this embodiment, the leveling detection member 190 is a bubble level.

[0069] Specifically, in this embodiment, referring to Figure 5As shown, the mounting member 110 is provided with a mounting groove 113. The bottom of the mounting groove 113 is arranged parallel to the reference plane 112. The leveling detection member 190 is arranged in the mounting groove 113 and abuts against the bottom of the mounting groove 113. And in the preset direction x, the depth of the mounting groove 113 is greater than the thickness of the leveling detection member 190, so that the leveling detection member 190 can be completely located in the mounting groove 113, and the mounting groove 113 can protect the leveling detection member 190 and reduce the impact on the leveling detection member 190.

[0070] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
