Description

Technical Field

[0001] The invention relates to the technical field of vertical placement of acoustic emission monitoring equipment, and in particular to a vertical placement device for acoustic emission monitoring equipment. Background Art

[0002] Landslide is a common natural geological disaster, and the collapse of mountains caused by landslide often brings great harm to the country and the people. Therefore, monitoring landslides and early forecasting of their harm can minimize and prevent the losses caused by them.

[0003] The rock and soil deformation monitoring device uses a standardized active waveguide acoustic emission monitoring unit, i.e., a waveguide tube. Figure 7 As shown in the figure, the waveguide tube mainly includes an outer tube (flexible hose) and an inner tube (metal waveguide tube), and the granular material is encapsulated in the annular columnar gap between the outer tube and the inner tube, and the upper and lower ends of the inner tube extend out of the upper and lower ends of the outer tube respectively; multiple waveguide tubes are connected in series up and down to form a linear array, which is called "array acoustic emission monitoring equipment". The equipment is embedded in the rock and soil bodies such as landslides through drilling holes, and can sensitively perceive the deep micro deformation of the slope body and continuously monitor the larger deformation, which solves the problems of real-time online monitoring of rock and soil deformation, state risk assessment, early warning and auxiliary decision-making, and provides effective technical support for revealing the evolution mechanism, prediction and forecasting of landslides and engineering prevention and control.

[0004] Since the waveguide is 1 meter long and weighs about 10 kg, the standard waveguide unit required for a monitoring point is usually as short as 6 meters or as long as more than 30 meters. This makes the total weight of the waveguide of the rock deformation monitoring device up to about 300 kg, which is the total weight of all the waveguides required for a monitoring point. At present, the on-site installation of the rock deformation monitoring device is not assisted by corresponding installation equipment, and mainly relies on manual and simple rope devices for installation; since the waveguide required for monitoring is long and heavy, and the terrain of the installation site is relatively complex, generally on the hillside, it is difficult to install on site; the main disadvantages are as follows: (1) When the waveguide is installed manually, due to uneven stress, the waveguide connection is easily deformed and damaged during the installation process, affecting the monitoring effect. (2) During the installation process, it is easy to cause destructive disturbance to the rock and soil in the borehole, and in severe cases, a collapsed hole will be formed, so that the waveguide installation cannot reach the predetermined layer, affecting the monitoring effect. (3) The installation efficiency is relatively low. Summary of the invention

DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Combine the following Figures 1 to 6 To describe the vertical delivery device of the acoustic emission monitoring equipment according to an embodiment of the present invention.

[0034] like Figures 1 to 6 As shown, the vertical delivery device of the acoustic emission monitoring equipment according to the embodiment of the present invention includes a hoisting system 100, a load-bearing protection device 200 and a leveling positioning device 300.

[0035] Specifically, if Figure 1 and Figure 2 As shown, the hoisting system 100 includes a bracket 10, a top plate 11, a fixed pulley 12 and a hoisting assembly 13. There are multiple brackets 10, for example, the number of brackets 10 can be three (see Figure 1), four, etc., the lower ends of the multiple brackets 10 are used to be stably fixed on the slope, and the tops of the multiple brackets 10 are connected to the top plate 11 to support the top plate 11, so that the top plate 11 can be suspended above the drilling hole in the slope. The multiple brackets 10 can be expanded outward and folded inward. When the vertical delivery device of the acoustic emission monitoring equipment is needed, the multiple brackets 10 can be expanded outward and stably fixed to the slope through the lower ends of the brackets 10 to stably support the top plate 11. When the vertical delivery device of the acoustic emission monitoring equipment is not needed, the multiple brackets 10 can be folded inward to save the space occupied by the hoisting system 100 and facilitate carrying. The multiple brackets 10 can be independently raised and lowered and adjusted. Due to the complex terrain of the slope, the height position of the top plate 11 can be adjusted by adjusting the height of each bracket 10, and the top plate 11 can be adjusted to a horizontal state. A mounting portion 111 is provided on the top plate 11, and the mounting portion 111 can be conveniently and detachably fixed to the fixed pulley 12 or the leveling positioning device 300. The fixed pulley 12 is detachably fixed to the mounting portion 111, so that the fixed pulley 12 can be fixed to the mounting portion 111 of the top plate 11 or can be removed from the top plate 11 as needed. The hoisting assembly 13 is arranged on one of the brackets 10 and passes through the fixed pulley 12, and is used to hoist the waveguide into the slope borehole. The waveguide can be understood as the standardized active waveguide acoustic emission monitoring unit (such as Figure 7 shown).

[0036] like Figure 3 and Figure 4 As shown, the bearing protection device 200 includes an orifice protection tube 20 and a bearing member 21. The bearing member 21 is arranged at one end of the orifice protection tube 20; the orifice protection tube 20 is used to be placed at the entrance end of the slope body drilling hole and the bearing member 21 is located outside the slope body drilling hole. The orifice protection tube 20 is placed at the entrance end of the slope body drilling hole to effectively protect the orifice of the slope body drilling hole, prevent the waveguide from being stuck due to stones falling from the orifice due to artificial disturbance during the installation of the waveguide, and ensure that the waveguide is always located at the center of the drilling hole during the placement process. The bearing member 21 is used for temporary bearing during the installation of the waveguide. In detail, during the installation of the waveguide, it is necessary to first temporarily bear the lower end of the waveguide through the bearing member 21, and then connect the upper end of the waveguide with the hanging assembly 13. Then, the bearing member 21 is opened, and the waveguide is lowered and installed in the drilled hole of the slope through the hanging assembly 13. When the waveguide is connected to the hanging assembly 13, the waveguide is temporarily supported by the bearing member 21, which can effectively prevent the waveguide from falling into the drilled hole of the slope due to top unloading during the installation process.

[0037] like Figure 5 and Figure 6As shown, the leveling positioning device 300 is used to be detachably fixed to the mounting portion 111 after the fixed pulley 12 is removed, so as to calibrate the position of the mounting portion 111 relative to the drilling hole of the slope, so as to ensure that after the fixed pulley 12 is connected with the top plate 11 and the hanging assembly 13, the hanging assembly 13 can conveniently and accurately drop the waveguide vertically into the drilling hole of the slope. In other words, the leveling positioning device 300 is used for positioning and leveling the bracket 10 and the top plate 11.

[0038] According to the vertical delivery device of the acoustic emission monitoring equipment of the embodiment of the present invention, the method and steps of use are as follows: after the vertical delivery device of the acoustic emission monitoring equipment of the embodiment of the present invention arrives at the site, first place the load-bearing protection device 200 in the entrance end of the slope drilling hole to ensure that the hole mouth protection tube 20 is located in the middle of the slope drilling hole; in this way, the slope drilling hole can be effectively protected to prevent the slope drilling hole from being destructively disturbed during the vertical delivery of the waveguide. Then, deploy multiple brackets 10 on site, preliminarily adjust the length of each bracket 10 according to the slope terrain, so that the top plate 11 is located directly above the slope drilling hole and at an appropriate height, and fix the connection between the bracket 10 and the top plate 11. Next, install the leveling device 300 at the installation part 111 of the top plate 11, and observe whether the leveling device 300 is located in the middle of the hole protection tube 20. If not, adjust the bracket 10 to move the top plate 11 until the leveling device 300 is located in the middle of the hole protection tube 20; then make the top plate 11 level by observing the level 32 of the leveling device 300 and adjusting the length of the bracket 10 by lifting and lowering, and then fix the lower end of the bracket 10 on the slope. Finally, remove the leveling device 300, install the fixed pulley 12, and pass the hanging assembly 13 through the fixed pulley 12. Adjust the hanging assembly 13 and install the waveguide.

[0039] The vertical delivery device of the acoustic emission monitoring equipment according to the embodiment of the present invention has the following advantages: first, it is simple and portable, applicable to various complex slope terrains, easy to operate, and improves installation efficiency; second, it can ensure that the waveguide is vertically and evenly stressed as a whole during the installation process, and can avoid damage to the waveguide due to uneven stress, thereby ensuring the integrity and monitoring effect of the acoustic emission monitoring equipment; third, it can effectively avoid secondary disturbance of the rock and soil in the slope borehole during the installation process, avoid secondary hole collapse in the hole, ensure that the acoustic emission monitoring equipment is installed to the predetermined layer, and ensure the monitoring effect.

[0040] In some embodiments, multiple brackets 10 are distributed around the top plate 11, and the upper ends of the multiple brackets 10 are pivotally connected to the top plate 11 respectively, so that the multiple brackets 10 can be expanded outward and folded inward; when the brackets 10 are in the expanded state, the top plate 11 limits the upper end of the brackets 10, so that the top plate 11 is reliably fixed on the multiple brackets 10 in the expanded state.

[0041] In some embodiments, each bracket 10 includes a first bracket 101, a second bracket 102 and an adjusting member 103; the first bracket 101 is provided with a fixing hole 1011, and the second bracket 102 is arranged with a plurality of adjusting holes 1021 along its length direction, and the first bracket 101 and the second bracket 102 can overlap each other in an up-and-down manner, and the adjusting member 103 is fixed in the fixing hole 1011 at the overlapping part of the first bracket 101 and the second bracket 102 and the adjusting hole 1021 directly opposite to the fixing hole 1011. Therefore, when it is necessary to adjust the length of the bracket 10, the adjusting member 103 is removed, the first bracket 101 or the second bracket 102 is moved, and the fixing hole 1011 is directly opposite to different adjusting holes 1021, and then the adjusting member 103 is passed through the fixing hole 1011 and the adjusting hole 1021 directly opposite to the fixing hole 1011, so as to realize the lifting and lowering adjustment function of the bracket 10, that is, to realize the length adjustment of the bracket 10, which can be applied to larger slopes on site.

The adjustment range is 0-0.5 meters, which can adapt to slopes with larger slopes on site.

[0044] The lower end of each bracket 10 is provided with a pivotally connected stable base 104, which can increase the force-bearing area. The stable base 104 is pivotally connected to the bracket 10, which is conducive to fixing the stable base 104 to the surface of the slope at different angles. The stable base 104 is used to be fixed to the slope by means of safety nails (not shown in the figure), so that the bracket 10 can be reliably fixed to the slope.

[0045] Specifically, the stable base 104 is pivotally connected to the lower end of the second bracket 102 , and a through hole is provided on the stable base 104 for a safety bolt to pass through.

[0046] In some embodiments, the extension direction of the pivot axis of the upper end of each bracket 10 is consistent with the extension direction of the pivot axis of the stable base 104 located at the lower end, which is reasonable in design and easy to use.

[0047] In some embodiments, the mounting portion 111 is a mounting hole located on the top plate 11. The mounting hole is more convenient and reliable for fixing the fixed pulley 12 and the leveling positioning device 300.

Specifically, the fixed rod 121 is provided with a thread, and the fixed rod 121 passes through the mounting hole from below and cooperates with the nut, thereby realizing that the fixed pulley 12 is fixed on the top plate 11.

[0049] In some embodiments, the lifting assembly 13 includes a base 131, a winch 132, a rope 133 and a connector 134; the base 131 is fixed on the bracket 10; the winch 132 is arranged on the base 131 and has an automatic braking function, and the automatic braking function for ascending and descending can be set to ensure the safety during the lifting process; the rope 133 can be a steel wire, a part of the rope 133 is wound on the winch 132 and the other part extends out of the winch 132 and passes through the fixed pulley 12, the end of the extended part of the rope 133 is connected to the connector 134, and the connector 134 is used to connect the upper end of the waveguide.

[0050] In some embodiments, an annular disk 201 is provided at one end of the orifice protection tube 20; the bearing member 21 includes two bearing blocks 211, the two bearing blocks 211 respectively have concave portions opposite to each other, and the concave portions may be semicircular, one end of the two bearing blocks 211 is coaxially pivotally connected and mounted on the annular disk 201, and the other ends of the two bearing blocks 211 are detachably fixed. When the bearing member 21 is used, the two bearing blocks 211 are closed, holding the outer periphery of the inner tube protruding from the lower end of the waveguide, and the other ends of the two bearing blocks 211 are fastened to each other, and at the same time, the end face of the outer tube at the lower end of the waveguide is supported on the upper surfaces of the two bearing blocks 211; then, the connector 134 at the end of the protruding portion of the rope 133 can be connected to the inner tube protruding from the upper end of the waveguide; after that, the two bearing blocks 211 are opened, the rope 133 is released by the winch 132, and the waveguide is directly placed into the slope drilling hole.

[0051] It should be noted that a handle 212 is provided at the other end of the two bearing blocks 211 to facilitate opening and closing the two bearing blocks 211 .

[0052] In some embodiments, the inner diameter of the orifice protection tube 20 is larger than the outer diameter of the outer tube of the waveguide, and the inner diameter of the support 21 is equal to the outer diameter of the inner tube of the waveguide.
