A rock breaking and tunneling detection device based on water jet cutting

Abstract

The present invention discloses a rock-breaking and tunneling detection device based on water jet cutting, which relates to the technical field of on-site rock hardness detection. The device comprises a limiting unit, including a vertical fixing assembly, a guide assembly, and a horizontal fixing assembly; and a drill bit tunneling unit, including a mounting box, a first cylinder, and a drill bit assembly. The beneficial effects of the present invention are as follows: through the efficient coordinated operation of the water jet cutting unit and the drill bit tunneling unit, the water jet is used to pre-cut the rock surface to form grooves to disrupt the stress distribution. The water pressure and drill bit parameters are dynamically adjusted by combining a feedback mechanism based on the cutting depth and the drilling effect. This allows rock hardness data to be obtained without replacing the drill bit on-site, allowing the appropriate drill bit type to be selected. This reduces the problem of reduced detection efficiency caused by frequent drill bit replacement during on-site testing.

Description

Technical Field

[0001] The present invention relates to the technical field of on-site rock hardness detection, in particular to a rock breaking and tunneling detection device based on water jet cutting. Background Art

[0002] Traditional on-site drilling inspections suffer from three major pain points: First, relying on experience to preselect drill bits leads to frequent drill bit changes in complex rock formations (an average of four times per day), with each change taking over 30 minutes and resulting in a 15% loss in project progress. Second, failure to pre-relieve rock surface stress increases the risk of drill bit deflection and fracture by 22% and consumable costs. Third, a lack of real-time rock property feedback leads to a 40% rate of manual misjudgment in heterogeneous formations. These issues lead to low drilling efficiency (average rate of only 1.1 m / h) and skyrocketing inspection costs, severely hampering engineering reliability in complex scenarios such as deep tunnels and altered rock formations.

[0003] At the drilling site, rock samples are tested using miniaturized testing equipment. However, existing testing devices drill rocks with a drill bit and obtain rock data by replacing the drill bit. Although the drill bit of the testing equipment is miniaturized and more convenient to replace than the large drill bit of the drilling equipment, frequent replacement of the drill bit during the testing process still wastes a lot of time and reduces work efficiency.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a rock breaking and tunneling detection device based on water jet cutting, comprising a limiting unit 1, a vertical fixing component 11, guide components 12 arranged on and on both sides of the vertical fixing component 11, and a horizontal fixing component 13 arranged at the movable end of the guide component 12;

[0041] It should be noted that the vertical fixing assembly 11 is fixedly installed on site and is used to fix the rock in the vertical direction. The guide assembly 12 is fixedly connected to the vertical fixing assembly 11 and both sides. The movable end of the guide assembly 12 is fixedly connected to the horizontal fixing assembly 13. The horizontal fixing assembly 13 is used to fix the rock in the horizontal direction.

[0042] The drill bit driving unit 2 includes a mounting box 21 disposed at one end of the guide assembly 12, a first cylinder 22 disposed between the mounting box 21 and the horizontal fixing assembly 13, and a drill bit assembly 23 disposed on a side of the mounting box 21 close to the horizontal fixing assembly 13;

[0043] It should be noted that the installation box 21 is fixedly installed at the moving end of the guide assembly 12, a first cylinder 22 is provided between the installation box 21 and the horizontal fixing assembly 13, and a drill assembly 23 is provided on the side of the installation box 21 close to the horizontal fixing assembly 13;

[0044] The water jet cutting unit 3 includes a three-axis moving assembly 31 disposed on the vertical fixing assembly 11, a water jet cutter head 32 disposed at the output end of the three-axis moving assembly 31, and a wastewater collection assembly 33 disposed below the water jet cutter head 32;

[0045] It should be noted that a three-axis moving assembly 31 is fixedly mounted on the top left side of the vertical fixing assembly 11. The three-axis moving assembly 31 is fixedly connected to a bracket extending from the left side of the vertical fixing assembly 11. A water jet cutter head 32 is fixedly connected to the output end of the three-axis moving assembly 31, and a wastewater collection assembly 33 is provided below the water jet cutter head 32.

[0046] The loading unit 4 includes a fourth cylinder 41 disposed between the vertical fixing assembly 11 and the horizontal fixing assembly 13 , and a pushing assembly 42 disposed outside one end of the guide assembly 12 .

[0047] It should be noted that a fourth cylinder 41 is provided between the vertical fixing assembly 11 and the horizontal fixing assembly 13. The fixed end of the fourth cylinder 41 is installed on the vertical fixing assembly 11, and the telescopic end of the fourth cylinder 41 is installed on the horizontal fixing assembly 13. The remaining part of the fixed end of the fourth cylinder 41 is placed on the guide assembly 12. The fourth cylinder 41 extends to push the horizontal fixing assembly 13 to move to the pushing assembly 42, and the pushing assembly 42 pushes the rock into the horizontal fixing assembly 13. The fourth cylinder 41 contracts to drive the rock to move into the vertical fixing assembly 11.

[0048] When in use, the rock sampled on site is placed in the pushing assembly 42, and the fourth cylinder 41 extends to push the horizontal fixing assembly 13 to move to the pushing assembly 42. The pushing assembly 42 pushes the rock into the horizontal fixing assembly 13, and the fourth cylinder 41 contracts to drive the rock to move into the vertical fixing assembly 11 to complete the loading.

[0049] The vertical fixing assembly 11 first fixes the rock in the vertical direction, and then the horizontal fixing assembly 13 fixes the rock in the horizontal direction, completing the preparation work before drilling;

[0050] The three-axis moving assembly 31 is started to drive the water jet cutter head 32 to move to one side of the rock. The water jet cutter head 32 cuts a groove of a certain depth on the rock surface to destroy the stress on the rock surface. Then the first cylinder 22 is retracted to drive the drill bit assembly 23 close to the rock and drill the rock surface. If the rock cannot be drilled through, the first cylinder 22 drives the drill bit assembly 23 to reset. The three-axis moving assembly 31 drives the water jet cutter head 32 to cut the rock again, and at the same time increases the water pressure to increase the cutting depth. Drilling is repeated, and the magnitude of the destructive stress is fed back through the cutting depth to determine the appropriate drill bit type.

[0051] In summary, through the efficient coordinated operation of the water jet cutting unit 3 and the drill bit excavation unit 2, the water jet is used to pre-cut the rock surface to form grooves to destroy the stress distribution, and the water pressure and drill bit parameters are dynamically adjusted in combination with the feedback mechanism of the cutting depth and the drilling effect. The rock hardness data can be obtained without replacing the drill bit on site, and then the appropriate drill bit type can be selected, thereby reducing the problem of reduced detection efficiency caused by frequent replacement of the drill bit 232 during on-site detection; the integrated automatic loading unit 4 realizes rapid positioning and transportation of rocks, and optimizes environmental protection and operation safety through wastewater recovery components and double fixed design. It has the characteristics of high efficiency, adaptability and intelligence, and is suitable for complex engineering scenarios such as geological exploration and tunnel excavation.

[0052] like Figure 2 and Figure 9As shown, as an optional embodiment: the vertical fixing assembly 11 includes a base 111 disposed on the ground, support columns 112 disposed at each inflection point of the base 111, a fixing base 113 disposed at the top of the support column 112, and a second cylinder 114 disposed on the lower surface of the fixing base 113;

[0053] The base 111 is connected to a fixed end of the fourth cylinder 41 .

[0054] It should be noted that the base 111 can be installed on site by pre-setting a foundation pit on site, and a support column 112 is fixedly connected to each inflection point of the base 111, the top of the support column 112 is fixedly connected to a fixing seat 113, the lower surface of the fixing seat 113 is fixedly connected to the second cylinder 114, and the vertical fixing assembly 11 is connected to the fixed end of the fourth cylinder 41 through the base 111.

[0055] During use, when the rock moves between the base 111 and the fixing seat 113, the second cylinder 114 extends and squeezes the rock to achieve vertical fixation of the rock, preventing vertical vibration during the drilling process, which may lead to inaccurate detection data.

[0056] like Figure 3 and Figure 9 As shown, as an optional embodiment: the guide assembly 12 includes a first support frame 121 provided on the left side of the base 111, a second support frame 122 provided on the right side of the base 111, a guide rail 123 provided on the first support frame 121, the second support frame 122, and the top of the base 111, and a slider 124 provided on the guide rail 123;

[0057] The remaining portion of the fixed end of the fourth cylinder 41 rests on the first support frame 121 , and the pushing assembly 42 is located outside one end of the second support frame 122 .

[0058] It should be noted that the left and right sides of the base 111 are respectively fixedly connected to the first support frame 121 and the second support frame 122, and the guide rail 123 is fixedly connected to the first support frame 121, the second support frame 122 and the top of the base 111, and the slider 124 is fixedly connected to the guide rail 123.

[0059] When in use, sliders 124 are installed at the bottom of the installation box 21, the limiting plate 131, and the fixing plate 132. The limiting plate 131 and the installation box 21 are connected by the first cylinder 22, so that the installation box 21 and the horizontal fixing assembly 13 can move together. Therefore, by extending and retracting the fourth cylinder 41, the installation box 21 and the horizontal fixing assembly 13 can be pushed and pulled to slide more smoothly on the guide rail 123 through the slider 124, thereby reducing the driving pressure of the fourth cylinder 41.

[0060] like Figure 3 and Figure 9 As shown in the figure, as an optional embodiment, the horizontal fixing assembly 13 includes a limiting plate 131 provided on the slider 124, a fixing plate 132 provided on the slider 124, connecting columns 133 provided between the limiting plate 131 and each corner of the fixing plate 132, a base 134 provided on the two bottom connecting columns 133, and a third cylinder 135 provided on the inner side of the fixing plate 132;

[0061] The telescopic end of the fourth cylinder 41 is connected to the limiting plate 131 .

[0062] It should be noted that the slider 124 is fixedly connected to a limiting plate 131 and a fixed plate 132, and the two are fixedly connected by a connecting column 133. The base 134 is fixedly connected to the two connecting columns 133 located at the bottom corners, and the third cylinder 135 is fixedly connected to the inner side of the fixed plate 132. The limiting plate 131 and the installation box 21 are connected by the first cylinder 22, and the horizontal fixing assembly 13 is connected through the limiting plate 131 and the telescopic end of the fourth cylinder 41.

[0063] During use, the fourth cylinder 41 pushes the limit plate 131 to move the base 134 to the loading area, and the rock is pushed onto the base 134. The rock is carried by the base 134. When it moves to the fixed area, the third cylinder 135 extends to squeeze the rock. The limit plate 131 and the third cylinder 135 squeeze the rock to achieve horizontal fixation of the rock.

[0064] like Figures 4 and 5 As shown, as an optional embodiment: the drill assembly 23 includes a mounting plate 231 provided on one side of the mounting box 21, a drill bit 232 rotatably provided on the mounting plate 231, a drill motor 233 provided on the mounting box 21, a transmission gear 234 provided at the output end of the drill motor 233, and a driven gear 235 provided at one end of the drill bit 232;

[0065] The teeth of the transmission gear 234 mesh with the teeth of the driven gear 235 .

[0066] It should be noted that a mounting plate 231 is fixedly connected to one side of the mounting box 21, a drill bit 232 is rotatably connected to the inner cavity of the mounting plate 231, a drill motor 233 is fixedly connected to one side of the inner wall of the mounting box 21, a transmission gear 234 is fixedly connected to the output end of the drill motor 233, and a driven gear 235 is fixedly connected to one end of the drill bit 232.

[0067] During use, the drill motor 233 is started to drive the transmission gear 234 to rotate, and then the drill bit 232 is driven to rotate through the driven gear 235. The first cylinder 22 is contracted to drive the rotating drill bit 232 close to the rock to achieve drilling.

[0068] like Figures 1 to 6 As shown, as an optional embodiment: the three-axis moving assembly 31 includes linear assemblies 311, and the number of linear assemblies 311 is three groups, namely, an X-axis linear assembly, a Y-axis linear assembly, and a Z-axis linear assembly;

[0069] The X-axis linear assembly is horizontally mounted on the fixed seat 113, the fixed end of the Y-axis linear assembly is fixedly connected to the movable end of the X-axis linear assembly, the movable end of the Y-axis linear assembly is fixedly connected to the movable end of the Z-axis linear assembly, and the water jet cutter head 32 is fixedly mounted on the fixed end of the Z-axis movable assembly;

[0070] The linear assembly 311 includes a fixed housing 3111, a linear motor 3112 disposed at one end of the fixed housing 3111, a screw rod 3113 disposed at the output end of the linear motor 3112, and a connecting block 3114 slidably disposed on the fixed housing 3111.

[0071] The connecting block 3114 and the screw rod 3113 are threadedly connected.

[0072] It should be noted that the linear assembly 311 is composed of three groups, and a three-axis moving assembly 31 is formed by installing them in the three directions of X-axis, Y-axis, and Z-axis. The linear assembly 311 includes a fixed end: a fixed shell 3111, and a moving end: a connecting block 3114. A linear motor 3112 is fixedly connected to one end of the fixed shell 3111, and a screw rod 3113 is fixedly connected to the output end of the linear motor 3112. The screw rod 3113 and the connecting block 3114 are threadedly connected.

[0073] When in use, the water jet cutter head 32 is moved by the coordinated movement between the three groups of linear components 311, and in the undetected state and after the cutting is completed, the three-axis moving component 31 will drive the water jet cutter head 32 away from the rock to prevent it from affecting the drilling of the drill bit 232.

[0074] like Figures 1 to 8 As shown, as an optional embodiment: the wastewater collection component 33 includes a collection pipe 331 arranged on the outer wall of one side of the limiting plate 131 and a guide pipe 332 arranged on the outer wall of the base 111.

[0075] It should be noted that a collecting pipe 331 is fixedly connected to the outer wall of one side of the limiting plate 131. The collecting pipe 331 is a Y-shaped pipe with an open top. A guide pipe 332 is fixedly connected to the outer wall of the base 111. The top of the guide pipe 332 is designed to be open, and its top inner cavity is designed to be inclined.

[0076] When in use, after the Y-shaped pipe collects wastewater, the wastewater flows into the guide pipe 332 from the bottom of the pipe. Since the top of the guide pipe 332 is designed with an opening to prevent interference when the collection pipe 331 moves with the limit plate 131, the wastewater will flow along the inclined surface of the inner cavity at the top of the guide pipe 332 and be discharged into the sewer.

[0077] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
