Description

Technical Field

[0001] The invention relates to the technical field of underwater construction equipment, and in particular to an underwater rock breaking device for river channel management. Background Art

[0002] Since landslides and mud-rock flows can easily cause large rocks to accumulate in river channels, thereby interfering with the speed and direction of water flow and affecting many aspects such as the stability of the river channel and the ecological environment, it is necessary to process the underwater rocks.

[0036] The crushing mechanism includes a support frame 51, and the three support frames 51 are evenly connected to the bottom of the sliding cylinder 3 by bolts. The ends of the three support frames 51 away from each other are rotatably connected with a rotating sleeve 52, and the three rotating sleeves 52 are slidably connected with sliding tubes 53. The lower part of the sliding tube 53 is provided with a plurality of through holes, and the plurality of through holes of the sliding tube 53 are connected with the interior of the sliding tube 53. The rotating sleeve 52 is used to drive the sliding tube 53 to rotate.

The interfaces of 55 are respectively communicated with the interiors of the three sliding tubes 53, the bottom of the sliding tube 3 is connected with a waterproof motor 56 by bolts, the output shaft of the waterproof motor 56 is connected with a double-layer gear 571 by a keyway, the three support frames 51 are rotatably connected with a screw rod 58, the three screw rods 58 are respectively threadedly connected to the middle parts of the three lifting frames 55, the bottoms of the three screw rods 58 are connected with a first gear 572 by a keyway, the three first gears 572 are meshed with the upper gear rings of the double-layer gear 571, the bottoms of the three rotating sleeves 52 are connected with a second gear 573 by a keyway, the three second gears 573 are meshed with the lower gear rings of the double-layer gear 571, and the several through holes of the three sliding tubes 53 are slidably connected with sliding columns 59, and the sliding columns 59 are used to crack the rock from the inner wall of the hole in the rock.

[0037] It also includes a clamping mechanism, which is arranged on the clamping arm 44 and is used to clamp the rock. The clamping mechanism includes a rotating plate 81. Eight rotating plates 81 are rotatably connected to the three clamping arms 44 at even intervals. The eight rotating plates 81 on the same clamping arm 44 form a group. There are three groups of rotating plates 81 in total. The three groups of rotating plates 81 are used to clamp the grooves and protrusions on the surface of the rock. The two ends of each rotating plate 81 are respectively connected to the clamping arm 44 with a torsion spring 82, and the two torsion springs 82 on the same rotating plate 81 are symmetrically arranged.

[0038] It also includes a protective cover 9, which is connected between the three support frames 51 by bolts, and is used to intercept debris such as aquatic plants.

[0039] First, the operator hangs the lifting ring 1 on the hook of the ship-borne crane, and at the same time connects the hydraulic pump to the interfaces of the three lifting frames 55 through the hydraulic pipe. Then the operator moves to the top of the underwater rock through the ship-borne crane control device, and then moves downward to approach the rock through the ship-borne crane control device. When the rock is located between the three clamping arms 44, the operator controls the telescopic rod of the hydraulic rod 21 to move downward and extend. The extension of the telescopic rod of the hydraulic rod 21 will push the sliding cylinder 3 to move downward. The downward movement of the sliding cylinder 3 will pull the three second connecting rods 42 to rotate downward through the three first connecting rods 41. The downward rotation of the three second connecting rods 42 will respectively drive the three clamping arms 44 to approach each other. At the same time, the three third connecting rods 43 ensure that the three clamping arms 44 are always kept at the bottom of the sliding cylinder 3. The rock is held vertically, and the three clamping arms 44 approach each other to clamp the rock, thereby fixing the device on the rock. While the three clamping arms 44 clamp the rock, the three groups of rotating plates 81 will contact the rock, and the eight rotating plates 81 in each group will rotate upward at different angles according to the depressions and protrusions on the surface of the rock, and the torsion spring 82 twists. The torsion force of the torsion spring 82 causes the rotating plates 81 to continuously apply pressure to the surface of the rock. In this way, while the clamping arms 44 clamp the rock, the three groups of rotating plates 81 will clamp the grooves and protrusions on the surface of the rock, thereby better clamping the rock with irregular surface, thereby making the device more stable on the rock, thereby enhancing the breaking effect of the underwater rock; after the device is fixed on the rock, the operator controls the output shaft of the waterproof motor 56 to rotate, and the waterproof motor 5 The output shaft of 6 rotates to drive the double-layer gear 571 to rotate, so that the upper gear ring of the double-layer gear 571 drives the three first gears 572 to rotate, and the rotation of the three first gears 572 drives the three screw rods 58 to rotate respectively, and the rotation of the three screw rods 58 drives the three sliding tubes 53 to move downward through the three lifting frames 55 respectively, and at the same time, the lower gear ring of the double-layer gear 571 drives the three second gears 573 to rotate, and the rotation of the three second gears 573 drives the three sliding tubes 53 to rotate respectively through the three rotating sleeves 52, so that the three sliding tubes 53 move downward and rotate at the same time, and then the three sliding tubes 53 drive the three drill bits 54 to drill holes in the rock, and at the same time, the protective cover 9 protects the double-layer gear 571, the first gear 572 and the second gear 573. , thereby preventing water plants and other debris from being drawn in from the bottom. When the drill bit 54 drills into the rock to a certain depth, the operator turns off the waterproof motor 56 and controls the hydraulic pump to pump the hydraulic oil into the three sliding tubes 53 through the three lifting frames 55. The hydraulic oil pressure in the three sliding tubes 53 gradually increases, causing the hydraulic oil to squeeze a number of sliding columns 59 to extend outward. After the sliding columns 59 extend, they squeeze the inner walls of the holes on the rock respectively. The pressure in the sliding tubes 53 continues to increase, causing the several sliding columns 59 to break the rock from the inner walls of the holes in the rock. In this way, after the drill bit 54 drills a hole in the rock, it squeezes the inner walls of the hole in the rock through the several sliding columns 59, thereby breaking the rock, making it easier to clean the rock, thereby further enhancing the effect of breaking the underwater rock.After the rock is broken, the operator uses the hydraulic pump to extract the hydraulic oil in the sliding tube 53. After the hydraulic oil in the sliding tube 53 is extracted, negative pressure is generated in the sliding tube 53, so that the plurality of sliding columns 59 are reset. Then the operator controls the output shaft of the waterproof motor 56 to rotate in the opposite direction. The reverse rotation of the output shaft of the waterproof motor 56 will drive the double-layer gear 571 to rotate in the opposite direction. The reverse rotation of the double-layer gear 571 will drive the lifting frame 55 to reset through the first gear 572 and the screw rod 58. The reset of the lifting frame 55 will drive the sliding tube 53 to reset. Then the operator controls the telescopic rod of the hydraulic rod 21 to drive the sliding cylinder 3 to reset. The reset of the sliding cylinder 3 will drive the three second connecting rods 42 to rotate upward and reset through the three first connecting rods 41, so that the three clamping arms 44 are reset. Then the operator controls the clamping arms 44 to clamp the broken rock through the hydraulic rod 21. After clamping the broken rock, the operator controls the ship-borne crane to lift the device upward, and then salvages the broken rock. Repeat this process until the operator salvages the remaining broken rock. ;

[0040] Embodiment 2: Based on embodiment 1, Figure 1-Figure 15 As shown, it also includes a reinforcement mechanism, which is arranged on the clamping arm 44, and is used to increase the friction between the clamping arm 44 and the rock. The reinforcement mechanism includes a guide rod 61, and the three guide rods 61 are respectively connected to the sides of the three clamping arms 44 away from each other by bolts, and the three clamping arms 44 are slidably connected with sliding frames 62, and the tops of the two ends of the sliding frames 62 are provided with rod-shaped structures, and the middle parts of the three sliding frames 62 are respectively slidably connected to the three guide rods 61, and the three guide rods 61 are respectively connected to the three sliding frames 62 with first pressure springs 63, and the two ends of the three sliding frames 62 are rotatably connected with rotating rods 64, and the two rotating rods 64 on the same sliding frame 62 are a group, and the rotating rods 64 are three groups in total, and the two rotating rods 64 in the same group are symmetrically arranged, and the rotating rods 64 are away from the clamping A spiral groove is provided on one end of the arm 44, and a synchronous frame 66 is connected to the side away from each other by bolts. The two ends of the bottom of the three synchronous frames 66 are respectively slidably connected to the spiral grooves of the three groups of rotating rods 64. The synchronous frame 66 is used to drive the rotating rods 64 to rotate through the spiral grooves of the rotating rods 64. Contact rods 65 are slidably connected to both ends of the three sliding frames 62. The end of the contact rod 65 close to the sliding cylinder 3 is a spiral structure. The two contact rods 65 on the same group of rotating rods 64 form a group. There are three groups of contact rods 65 in total, and the two contact rods 65 in the same group are symmetrically arranged. The ends of the six contact rods 65 away from the sliding cylinder 3 are respectively slidably connected to the ends of the six rotating rods 64 close to the sliding cylinder 3. Second pressure springs 67 are connected between the six contact rods 65 and the six rotating rods 64, respectively.

[0041] The spiral structure of the contact rod 65 is made of cemented carbide, and the spiral structure of the contact rod 65 made of cemented carbide is used to better drill into the rock surface.

[0042] When the clamping arm 44 clamps the rock, the spiral structure of the contact rod 65 will first contact the rock. The clamping arm 44 continues to move toward the rock for a certain distance to squeeze the contact rod 65 and move it in the sliding frame 62 toward the rotating rod 64. The second pressure spring 67 is compressed. The pressure of the second pressure spring 67 causes the contact rod 65 to continue to squeeze the surface of the rock through the spiral structure of the contact rod 65. Then the sliding frame 62 will press against the rock surface. The clamping frame continues to move so that the rock squeezes the sliding frame 62 to move in the direction away from the sliding cylinder 3. The first pressure spring 63 is compressed. When the sliding frame 62 moves, it will drive the rotating rod 64 to move, so that The step frame 66 drives the rotating rod 64 to rotate through the spiral groove of the rotating rod 64, and the rotation of the rotating rod 64 will drive the contact rod 65 to rotate. In this way, the spiral structure of the contact rod 65 made of cemented carbide exerts pressure on the rock and rotates to drill into the surface of the rock, which is beneficial to increase the friction between the rock and the clamping arm 44, thereby making the breaking of the rock more stable, thereby further enhancing the breaking effect of the underwater rock; when the clamping arm 44 is reset, the rock no longer squeezes the sliding frame 62 and the contact rod 65, and the second pressure spring 67 is reset to drive the contact rod 65 to reset, and at the same time, the first pressure spring 63 is reset to drive the sliding frame 62 to reset.

[0043] Embodiment 3: Based on embodiment 2, Figure 1-Figure 15 As shown, it also includes a bottom mechanism, which is arranged on the clamping arm 44, and is used to hook the bottom of the rock. The bottom mechanism includes a support column 71, and the three support columns 71 are respectively connected to the through holes of the three clamping arms 44 by bolts. The two ends of the three support columns 71 are rotatably connected with a rotating bar 72, and the two rotating bars 72 on the same support column 71 are a group. There are three groups of rotating bars 72 in total, and the two rotating bars 72 in the same group are symmetrically arranged. The tops of the six rotating bars 72 are each provided with two bar grooves, and the two ends of the three sliding frames 62 are each provided with sliding bars. A sliding sleeve 73 is movably connected, and the two sliding sleeves 73 on the same sliding frame 62 form a group. There are three groups of sliding sleeves 73 in total. The two sliding sleeves 73 in the same group are symmetrically arranged. Tension springs 74 are connected between the six sliding sleeves 73 and the two ends of the three sliding frames 62 respectively. The tops of the six sliding sleeves 73 are respectively in contact with the rod-shaped structures at the two ends of the three sliding frames 62. The rod-shaped structures of the sliding frames 62 are used to resist the sliding sleeves 73. The two ends of the six sliding sleeves 73 are respectively slidably connected to the two bar grooves of the six rotating bars 72, and the sliding sleeves 73 are used to drive the rotating bars 73 to rotate.

[0044] The rotating bar 72 is in an arc-shaped structure, and the rotating bar 72 in the arc-shaped structure is used to hook the bottom of the rock.

[0045] At first, the rod-shaped structure of the sliding frame 62 presses against the sliding sleeve 73, and the sliding sleeve 73 pulls the rotating bar 72. When the sliding frame 62 moves in the direction away from the sliding cylinder 3, the sliding sleeve 73 is pulled to move together through the tension spring 74. The movement of the sliding sleeve 73 drives the rotating bar 72 to rotate through the bar groove of the rotating bar 72. Then, the other end of the rotating bar 72 with an arc structure hooks the bottom position of the rock. The sliding frame 62 continues to move, the tension spring 74 is stretched, and the rod-shaped structure of the sliding frame 62 no longer presses against the sliding sleeve 73. The tension of the tension spring 74 passes through the sliding sleeve 73 to make the rotating The other end of the bar 72 continuously applies pressure to the rock, so that the clamping arm 44 clamps the rock while hooking the rock from the bottom through the six arc-shaped rotating bars 72, thereby holding the rock tightly from multiple directions, making it difficult for the drill bit 54 to fall off the rock when drilling a hole in the rock, thereby further enhancing the breaking effect on underwater rocks; when the sliding frame 62 is reset, the tension spring 74 is reset, and at the same time, the rod-shaped structure of the sliding frame 62 again presses against the top of the sliding sleeve 73, and then the sliding frame 62 pushes the sliding sleeve 73 to reset, and the reset of the sliding sleeve 73 causes the rotating bar 72 to reset.
