[0001] The present invention relates to the technical field of dredging equipment, and more particularly to an environmentally friendly drilling ship and a method for using the same. Background Art

[0002] Dredging engineering refers to the use of rock digging ships, drilling ships, other machines and manual underwater excavation to dig and treat the bottom mud, sand, stones, etc. of waterways and port waters within a specified range and depth. Dredging engineering is one of the main means of developing, improving and maintaining waterways and port waters.

[0003] During the dredging project, the dredging ship first removes the silt, soft soil and gravel covering the rock and soil reefs. When the rock and soil reefs are difficult to dig, a drilling ship is needed to drill holes in the rock and soil reefs before crushing the rocks. The work of the drilling ship is to use the down-the-hole drilling equipment on the ship to drill holes on the rock and soil reefs. When the specified range and depth are reached, the dredging ship is used to break and dig away the gravel to reach the designed range and depth.

[0004] The drilling equipment currently in use, the down-the-hole drill used, only plays a drilling role when drilling. Although it can solve the problem of ordinary rock formations, the effect of rock and soil crushing is limited when the rock formation is thick or the rock formation is strong. This leads to the need for multiple slag cleaning and multiple drillings. The operation is difficult at sea, which brings great difficulties to the construction and leads to the problem of poor efficiency of project implementation.

[0005] Therefore, it is necessary to propose an environmentally friendly drilling ship and a method for using the same to improve its reef blasting efficiency. Summary of the invention

[0033] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of the various components of the present invention are not absolute but relative. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, the indications of these directions also change accordingly.

[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0037] See also Figure 1 , and combined with Figure 2 and Figure 3 As shown, an environmentally friendly drilling ship of the present invention comprises a moving mechanism and a mounting frame installed on the moving mechanism, wherein a submersible drill head 1 is installed on the mounting frame, and the submersible drill head 1 comprises a seat body 11, a rotating disk 12 is installed on the seat body 11, a guide beam 13 is installed on the rotating disk 12, a positioning drill bit 2 is installed at the end of the guide beam 13, guide frames 3 are respectively installed on both sides of the guide beam 13, and the guide frames 3 are respectively installed with a drill rod driven by a motor 4 and a hydraulic rod 51 driven by a driving cylinder 5, wherein a plurality of top pressure holes 52 are arranged on the hydraulic rod 51, and a protruding cutting plug 53 is telescopically sealed and installed in the top pressure hole 52.

[0038] The mobile mechanism of the present invention is generally a hull, or it can be a platform on the hull that can be adjusted left and right. When in use, the hull accurately positions the positioning drill bit 2 on the submersible drill bit 1 with the position to be excavated, determines the relative position of the hydraulic rod 51 on the turntable 12 and the opening, and uses the motor 4 to drive the drill rod to press against the rock wall to drill, and performs rapid drilling. When the hole is drilled to a predetermined depth, the drill rod is then withdrawn from the formed hole, and the turntable 12 is controlled to rotate to align the hydraulic rod 51 with the formed hole. Then, by controlling the protruding cutting plug 53 of the hydraulic rod 51 in the top pressure hole 52, the protruding cutting plug 53 is moved outward, and the hole can be drilled outward along the outer wall direction of the formed hole, thereby forming a hole-like structure on the inner side of the rock wall.

[0039] It should be noted that there are multiple top pressure holes 52 in the present invention, and they are evenly spaced on the hydraulic rod 51 and evenly arranged in an annular direction along its length direction. Therefore, when it expands outward, it can quickly squeeze along the radial and axial directions of the hole formed by the hydraulic rod 51, forming extrusion cracks on the surrounding walls of the hole or, when the hardness of the surrounding wall rock is not large, a hole-like structure can also be generated, providing prestress for subsequent rock drilling. Moreover, due to the existence of the extrusion force, cracks will appear in the rock on the surrounding wall, thereby increasing the crushing area of ​​one rock drilling and improving its reef blasting effect.

[0040] Of course, the drill rod 41 of the present invention is not only provided with a drill bit at the head for cutting, but also a spiral strip-shaped cutting edge can be provided on the drill rod 41.

[0041] It should be noted that the hydraulic rod 51 of the present invention includes a rod body with an oil passage therein and an extrusion body, a protruding cutting plug 53 is arranged on the extrusion body, and the extrusion body is sleeved in the rod body. When the hydraulic oil pressure in the oil passage rises, the protruding cutting plug 53 on the extrusion body is driven to be extruded out of the top pressure hole 52. Among them, the outer diameter of the extrusion body after contraction is smaller than the inner diameter of the rod body, and the outer diameter of the extrusion body after expansion is equal to the inner diameter of the rod body, that is, the inner diameter of the extrusion body of the present application is retractable.

[0042] Please continue reading Figure 3 and Figure 4 As shown, a guide block 131 is provided in the middle of the guide beam 13 of the present invention, and the guide frame 3 includes a mounting rod 31 and a guide rod 32 passed through the guide block 131, the mounting rod 31 and the guide rod 32 are arranged in parallel, and the top of the mounting rod 31 is connected to the top of the guide rod 32 through a connecting plate 33, and the bottom of the mounting rod 31 is connected to the positioning plate 34 at the bottom of the guide rod 32, so as to form a stable guide frame 3, providing a stable installation foundation for the drill rod 41 and the hydraulic rod 51.

[0043] Specifically, the guide beam 13 is installed in the middle of the rotary disk 12, and a mounting seat 61 is slidably installed on the mounting rod 31, and the motor 4 and the driving cylinder 5 are respectively installed on the two mounting seats 61.

[0044] In order to facilitate the stroke adjustment of the hydraulic rod 51 and the drill rod 41, the mounting seat 61 of the present invention and the mounted rod 31 are driven by an electric cylinder.

[0045] The seat body 11 of the present invention includes a base 62 and an angle adjustment cylinder 63. Mounting ears 65 are installed at both ends of the base 62. The angle adjustment cylinder 63 is installed on the mounting ears 65. The end of the telescopic rod of the angle adjustment cylinder 63 is connected to a connecting plate 66. The rotating disk 12 is installed on the connecting plate 66. For the specific structure, please refer to Figure 2 and Figure 3 shown.

[0046] When the position of the drill rod 41 or the hydraulic rod 51 is not appropriate, especially when the hydraulic rod 51 is aligned with the formed hole, the angle of the rotary disk 12 can be quickly adjusted by adjusting the angle adjustment cylinder 63 to control its alignment angle.

[0047] For a detailed description of the adjustment method of the hydraulic rod 51 of the present invention, please refer to Figure 6 and Figure 7As shown, the hydraulic rod 51 of the present invention includes an outer sleeve 54 and an inner sleeve 55. The inner sleeve 55 is sleeved inside the outer sleeve 54. The head of the inner sleeve 55 is provided with an oil inlet hole 56 and an oil return hole 57. The cutting plug 53 is fixed on the surface of the inner sleeve 55. The inner sleeve 55 is composed of a plurality of arc-shaped sealing plates 58 and a retractable arc plate 59. The arc-shaped sealing plates 58 are connected through the arc plate 59. When high-pressure oil enters through the oil inlet hole 56, the inner sleeve 55 expands, thereby driving the protruding cutting plug 53 on the outer circumferential surface of the inner sleeve 55 to protrude outward toward the top pressure hole 52 on the outer sleeve 54. Under the action of the high-pressure oil, the protruding cutting plug 53 acts on the inner edge surface of the hole wall. When the action is completed, the high-pressure oil is discharged from the oil return hole 57. The inner sleeve 55, which loses its force, contracts, driving the protruding cutting plug 53 to contract rapidly inward, and this is repeated. For the specific structure, please refer to Figure 6 and Figure 7 shown.

[0048] It should be noted that in order to prevent the protruding cutting plug 53 on the inner sleeve 55 from not corresponding to the top pressure hole 52 on the outer sleeve 54 after the inner sleeve 55 is opened, the present invention also provides a connector 67 fixed to the inner edge surface of the outer sleeve 54 on the top outer edge surface of the inner sleeve 55 to ensure that the inner sleeve 55 can expand and contract proportionally under the action of high-pressure oil.

[0049] Please continue reading Figure 2 As shown, the present invention also provides a method for using an environmentally friendly drilling vessel, comprising the following steps:

[0050] Step 1, control the mobile mechanism to the set reef blasting boat, and use the mounting frame to fine-tune the position to control the drilling accuracy;

[0051] Step 2, controlling the positioning drill bit 2 of the submersible drill head 1 to contact the reef, controlling the drill rod 41 to drill a hole into the reef through the rotary disk 12, and simultaneously cleaning the slag during the drilling;

[0052] Step 3, after the drilling is completed, the drill rod 41 is controlled to retract and clear the slag; the hydraulic rod 51 is aligned with the hole formed by the drill rod 41 by using the rotary plate 12, the guide frame 3 is controlled to move toward the reef side, and the hydraulic rod 51 is controlled to penetrate into the forming control;

[0053] Step 4, when the hydraulic rod 51 is in place, the protruding cutting plug 53 is driven to extend outward by the hydraulic cylinder, so that the protruding cutting plug 53 acts on the inner edge surface of the hole wall and generates a force on the action surface.

[0054] The environmentally friendly drilling ship of the present invention adopts a hydraulic rod 51 installed on a rotating disk 12, and its precise positioning can be achieved by using the positioning drill bit 2 in the middle. In combination with the drill rod 41 driven by the motor 4 and the hydraulic rod 51 driven by the driving cylinder 5, the drill rod 41 can be used to drill quickly. In combination with the function of the rotating disk 12, the hydraulic rod 51 can be driven to drive the hydraulic rod 51 forward quickly to drive the hydraulic rod 51 to expand the hole. At the same time, the protruding cutting plug 53 on the hydraulic rod 51 can be used to drive the protruding cutting plug 53 to move outward after the hole is drilled in place, so as to use the protruding cutting plug 53 to squeeze the inner side of the formed hole. On the one hand, the rock on the hole wall can be squeezed to cause cracks to be generated, thereby reducing the difficulty of rock drilling. On the other hand, due to its force on the rock on the hole wall, holes are generated on the hole wall, which provides more pores for later rock drilling and increases the blasting strength and effect.

[0055] Finally, the method of the present application is only a preferred implementation scheme and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
