Description

Technical Field

[0001] The invention belongs to the technical field of underwater drilling, and in particular relates to a drilling and blasting ship suitable for high flow rates. Background Art

[0002] With the continuous development of the national economy and the needs of national defense projects, underwater drilling and blasting technology has been widely used in many fields such as waterways, ports, water conservancy and hydropower, railway bridges, oil and gas pipelines, seismic exploration, underwater obstacle removal and protection projects, etc. It has a significant economic effect on the treatment of underwater rocks.

[0003] At present, the conventional underwater drilling construction technology is usually a "two-tube and one-drill" drilling method: "two-tube" refers to a casing and a drill rod, and "one drill" refers to the impactor drill bit. The "two-tube and one-drill" drilling technology has only one casing, which is installed section by section, usually 2.5m per section, and requires manual removal or installation of casing, which is cumbersome to operate; the "two-tube and one-drill" drilling technology uses hydraulic jacking to lower the casing; in addition, if the flow rate is high in waters, it is difficult for the drilling and blasting ship to remain stable and the drill rod cannot be accurately positioned to the drilling position. During underwater blasting, if the drilling position is inaccurate, it may lead to poor blasting effect, and the block of stone is too large or too small, which will affect the subsequent slag removal and construction progress.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0032] like Figures 1 to 12As shown, the present invention relates to a drilling and blasting ship suitable for high flow rate, comprising a drilling and blasting ship 1 and a drilling machine 4. A mounting frame 2 is provided on the drilling and blasting ship 1, an electric hoist 3 is provided on the mounting frame 2, and the drilling machine 4 is hoisted on a wire rope 31 of the electric hoist 3; the drilling machine 4 can be lowered to the riverbed by the electric hoist 3 to drill holes. In waters with high flow rate, the drilling and blasting ship 1 cannot remain stationary and has a large swing amplitude. At this time, the drilling machine 4 will also move with the ship hull. In order to enable the drilling machine 4 to always maintain an inconvenient position and accurately reach the drilling point, a first guide rail 21 and a second guide rail 22 for compensation of the movement of the power hoist 3 are provided on the mounting frame 2. The first guide rail 21 is perpendicular to the second guide rail 22 in the horizontal direction. The first guide rail 21 has two and is fixedly mounted on both sides of the top of the mounting frame 2 respectively. The two ends of the second guide rail 22 are slidably arranged on the two first guide rails 21, and the electric hoist 3 is slidably mounted on the second guide rail 22. A driving mechanism 23 for driving the first guide rail 21 to move is provided on the outer side of the guide rail 21, and an electric drive wheel 32 that can move along the second guide rail 22 is provided on the electric hoist 3. Specifically, in order to more accurately monitor the moving direction and distance of the drilling and blasting hull 1, a direction sensor and a displacement sensor for respectively detecting the moving direction and moving distance of the drilling and blasting hull 1 are also provided on the drilling and blasting hull 1. The data monitored by the direction sensor and the displacement sensor are transmitted back to the controller, and the controller controls the driving mechanism 23 and the electric hoist 3 to move compensation in the opposite direction of the drilling and blasting hull 1, thereby offsetting the swing of the drilling and blasting hull 1, so that the drilling machine 4 maintains the original lowering trajectory and is lowered until it falls on the rock layer of the riverbed; the drilling machine 4 includes a drill rod 41, a mounting block 42 for mounting the drill rod 41, and a first motor 43 for driving the drill rod 41 to rotate, the first motor 43 is installed in the mounting block 42, and the end of the wire rope 31 is connected to the mounting block 42.

[0033] In this embodiment, the driving mechanism 23 includes a first synchronous wheel 231, a second synchronous wheel 232, a synchronous belt 233 and a second motor 234. The first synchronous wheel 231 and the second synchronous wheel 232 are rotatably mounted on the outer wall of the first guide rail 21. The synchronous belt 233 is sleeved on the first synchronous wheel 231 and the second synchronous wheel 232. The output shaft of the second motor 234 is transmission-connected to the rotating shaft of the first synchronous wheel 231. Both ends of the second guide rail 22 are provided with a bearing block 221 mounted on the first guide rail 21. The outer side of the bearing block 221 is provided with a connecting plate 2211 fixedly connected to the synchronous belt 233. The connecting plate 2211 and the synchronous belt 233 can be connected by bolts, and can be disassembled when the synchronous belt 233 needs to be replaced. A through groove 211 for the connecting plate 2211 to pass through is formed on the side wall of the first guide rail 21. The second motor 234 is rotated forward and reversely to drive the synchronous belt 233 to move back and forth. Specifically, there are two groups of driving mechanisms 23, which are respectively installed on the two first guide rails 21. By driving the two groups of driving mechanisms 23 at the same time, the second guide rail 22 can move more smoothly.

[0034] In order to make the supporting block 221 move more smoothly, a supporting roller 2212 is provided at the bottom of the supporting block 221. A cavity is formed at the bottom of the supporting block 221. The supporting roller 212 is rotatably installed in the cavity, and at least two supporting rollers 212 are arranged side by side in each cavity. The supporting roller 2212 can reduce the friction between the supporting block 221 and the first guide rail 21.

[0035] In this embodiment, the drill rod 41 is detachably mounted on the mounting block 42, and the mounting block 42 is provided with a first clamping block 421 and a second clamping block 422 for fixing the drill rod 41, and a rotation groove is formed at the connection between the first clamping block 421 and the second clamping block 422, and the drill rod 41 is provided with a rotation block 411 that matches the rotation groove, and a bearing sleeved on the rotation block 411 is also installed in the rotation groove; the first clamping block 421 and the second clamping block 422 are connected to the bottom of the mounting block 42 through the first bolt 5. When installing the drill rod 41, the bearing is first installed on the rotation block 411, and then the first clamping block 421 and the second clamping block 422 are closed to the bearing so that the bearing is stuck in the rotation groove, and then the first clamping block 421 and the second clamping block 422 are fixedly installed on the bottom of the mounting block 42 through the first bolt 5. When installing the ring, it is also necessary to pay attention to connecting the output shaft of the first motor 43 with the drill rod 41, and specifically, the output shaft of the first motor 43 is connected to the drill rod 41 through a spline.

[0036] In this embodiment, when the drill rod 41 rotates, if there is no limit mechanism, the entire drilling machine 4 may rotate simultaneously with the drill rod 41, which will cause the drill rod 41 to perform invalid drilling. Therefore, a plurality of limit rods 44 are arranged in a circular array along the axis of the drill rod 41 at the bottom of the mounting block 42; the top of the limit rod 44 is hinged to the mounting block 42, and the end of the limit rod 44 is provided with a guide wheel 441, and a plurality of friction particles 4411 are formed on the guide wheel 441, and the end of the friction particle 4411 may be pointed. Specifically, the angle between the limit rod 44 and the drill rod 41 is about 30° in the natural state. As the drill rod 41 drills down, the guide wheel 441 on the limit rod 44 will drive the limit rod 44 to slide outward, thereby changing the angle between the limit rod 44 and the drill rod 41, and preventing the limit rod 44 from interfering with the drilling of the drill rod 41; the friction particles 4411 on the guide wheel 441 can play a limiting role, preventing the mounting block 42 from drilling at the same time as the drill rod 41.

[0037] In this embodiment, since the rock formation on the riverbed is in an uneven state, in order to make the limiting rod 44 adapt to the riverbed, specifically, the limiting rod 44 includes a sleeve rod 442 hinged to the bottom of the mounting block 42 and a telescopic rod 443 slidably mounted in the sleeve rod 442, and the guide wheel 441 is rotatably mounted on the end of the telescopic rod 443. When the limiting rod 44 just contacts the riverbed, the telescopic rod 443 can be adaptively contracted, so that the limiting rod 44 can better contact the riverbed.

[0038] In this embodiment, a plurality of counterweight blocks 6 are further provided on the mounting block 42, a plurality of fixing columns 423 are provided on the top of the mounting block 42, and fixing holes 61 are formed on the counterweight blocks 6 to cooperate with the fixing columns 423. The counterweight blocks 6 can be used to apply downward pressure, making it easier for the drill rod 41 to drill.

[0039] In this embodiment, a plurality of balancing mechanisms 45 are arranged in a circular array along the axis of the drill rod 41 on the side wall of the mounting block 42. The balancing mechanism 45 includes a rotorcraft 451 and a support plate 452. The rotorcraft 451 is arranged tilted, and the angle between the rotorcraft 451 and the drill rod 41 is 45°. The end of the support plate 452 is formed with a mounting plate 4521 connected to the mounting block 42, and the mounting plate 4521 is connected to the mounting block 42 by a second bolt 7. The rotorcraft 451 is arranged tilted at 45°, which can not only keep the drill rod 41 balanced, but also provide a downward thrust, which can reduce the use of the counterweight 6.

[0040] In this embodiment, a protective net 8 for protecting the balancing mechanism 45 is also provided on the mounting block 42; the protective net 8 includes an upper net body 81 and a lower net body, and the upper net body 81 and the lower net body are connected to the mounting block 42 by a third bolt 9; a first connecting ring 821 is provided at the top of the net circle of the lower net body, and an annular groove 8211 is formed on the first connecting ring 821, and a second connecting ring 811 is provided at the bottom of the net circle of the upper net body 81, and a plug-in ring matching the annular groove 8211 is formed on the second connecting ring 811. The protective net 8 can protect the rotorcraft 451 and prevent the rotorcraft 451 from being damaged by debris in the water. When the rotorcraft 451 needs to be repaired, the upper net body 81 and the lower net body can be disassembled before the rotorcraft 451 is repaired, which is more convenient to operate.

[0041] The method of using the present invention is as follows: first, the drilling and blasting hull 1 is moved to the drilling and blasting point, and then the drilling machine 4 is lowered by the electric hoist 3. If the drilling and blasting hull 1 swings during the lowering process, the electric hoist 3 can be corrected in position by the first guide rail 21 and the second guide rail 22, so that the drilling machine 4 maintains the original lowering trajectory for lowering, so that the drilling machine 4 accurately reaches the drilling point and performs the drilling operation. When drilling, the drilling machine 4 is kept balanced by multiple groups of rotorcraft 451, and the drilling machine 4 can be prevented from rotating under the action of the limit rod 44, thereby improving the drilling efficiency; when the hole is drilled, the explosives can be placed manually, or the explosives can be hung into the drilled hole in the same way as the drilling machine 4.

[0042] The above is a detailed introduction to a drilling and blasting ship suitable for high flow rate provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
