Description

Technical Field

[0001] The present invention relates to the technical field of rock drilling equipment installation, and in particular to an installation method for a rock drilling vessel. Background Art

[0002] Currently, underwater rock excavation primarily utilizes controlled blasting or percussive rock hammering. When drilling near buildings (structures), especially in narrow inland waters, near embankments, bridges, subway structures, and so on, to avoid impacting their structural safety, rock drills are typically used. The drills are raised to a certain height to convert their gravitational potential energy into impact force against the rock. However, during underwater drilling, the drill's energy is significantly weakened as the water depth increases, necessitating the drill be raised to a greater height. Furthermore, lifting the drill underwater is slow and inefficient, and the traction rope rubs repeatedly during the lifting process, resulting in frequent and costly replacements.

[0003] In order to solve the above problems, the inventors of the present application proposed a drilling vessel, which stably delivers the hydraulic impact drilling hammer to the underwater rock surface and ensures the stability of the vertical movement of the hydraulic impact drilling hammer, so that the hydraulic impact drilling hammer can drill underwater, and the lifting stroke of the hydraulic impact drilling hammer during the drilling process is short, which can improve construction efficiency and reduce the loss of the traction rope; however, this drilling vessel has a complex structure and is heavy, and how to ensure its installation is a problem that needs to be solved urgently. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art rock drilling vessel, such as its complex structure, heavy weight and difficulty in installation, and to provide an installation method for the rock drilling vessel.

[0005] The present invention provides an installation method for a rock drilling vessel, comprising the following steps:

[0006] S1. Weld two rails on the main deck of the ship along the longitudinal direction of the main deck;

[0007] S2. Install the running mechanism on the installed track so that there are two running mechanisms on each track, and temporarily fix the running mechanism to the track; wherein the running mechanism is engaged with the track and can be moved and fixed along the track;

[0008] S3. Hoist the traveling chassis onto the four traveling mechanisms and weld them;

[0009] S4. Hoist and install the winch, retractable support, and second-level platform on the traveling chassis, so that the retractable support and winch are located on both lateral sides of the vessel, and the second-level platform is fixed to the traveling chassis and located above the winch. The retractable support includes a main support and a first guide and stabilizing support. The bottom end of the main support is fixed to the traveling chassis, and the top end of the main support extends away from the vessel. One end of the first guide and stabilizing support is fixed to the main support, and the other end is arranged toward the outside of the vessel. The first guide and stabilizing support is a rectangular frame structure with guide rollers provided inside the rectangular frame structure. Related equipment is installed on the second-level platform.

[0010] S5. Install the hydraulic impact rock hammer into the guide rod frame and use the hydraulic cylinder to suspend the hydraulic impact rock hammer;

[0011] S6. Hoist the guide rod frame and hydraulic impact rock hammer into the rectangular frame structure and contact the guide rollers. Pass one end of the traction rope on the winch around the top of the main bracket and fix it to the hanging ear at the bottom of the guide rod frame. Connect the relevant hydraulic oil pipes and cables to complete the installation of the rock drilling ship.

[0012] In this solution, a track is first welded on the main deck of the ship to provide an installation basis for the installation of the walking mechanism; after the installation of the walking mechanism is completed, the walking mechanism is fixed on the track to provide stable installation conditions for the walking chassis; after the walking chassis is installed, the walking chassis, the walking mechanism and the track form a whole, which can be balanced and prevent overturning; then the winch, the retractable bracket and the second-layer platform are hoisted and installed on the walking chassis based on the walking chassis, so that the retractable bracket and the winch are respectively located on the lateral sides of the ship, and the second-layer platform is fixed on the walking chassis and located above the winch, making the ship more stable, and the installation of the main bracket of the retractable bracket, the first guide stabilizing bracket and the guide roller and the winch provides a basis for the subsequent overall hoisting of the guide rod frame and the hydraulic impact rock hammer.

[0013] This solution separates the hoisting of the trolley's components, including the track, chassis, travel mechanism, winch, retractable bracket, and second-level platform. This reduces weight and volume, making installation easier and safer. Furthermore, pre-installation provides a stable and balanced foundation for subsequent installation, making installation more efficient and safer while preventing tipping. Furthermore, the hydraulic jack hammer is pre-installed within the guide frame and hoisted as a single unit, eliminating the difficulty of installing the hydraulic jack hammer after the guide frame is installed. This makes the installation of heavy and complex rock drilling vessels simpler, more organized, more efficient, and safer.

[0014] Preferably, in step S1, a track installation line is drawn on the main deck of the ship, two tracks are installed on the main deck, the straightness of the installation is determined, and then the bottom surface of the track is welded and fixed to the main deck surface of the ship.

[0015] Can improve the installation quality and efficiency of the track.

[0016] Preferably, in step S2, the traveling mechanism is installed on the installed track, and the traveling mechanism is positioned according to the size of the traveling chassis.

[0018] Preferably, in step S3, the traveling chassis is hoisted onto the four traveling mechanisms, the clearances between the traveling wheels and the tracks of the traveling mechanisms are adjusted to ensure that the four traveling mechanisms do not twist, and then the traveling chassis is welded and fixed to the four traveling mechanisms to ensure the installation quality of the traveling mechanisms.

[0019] Preferably, the relevant equipment on the second-floor platform includes a generator set, an air compressor set and a hydraulic power station;

[0020] In step S4, the winch, the retractable bracket and the second-floor platform are installed in sequence, and then the relevant equipment on the second-floor platform is hoisted onto the second-floor platform.

[0021] It is helpful to reduce the difficulty of lifting.

[0022] Preferably, before step S5, the method further includes: selecting the length of the guide rod frame according to the water depth of the construction project to avoid construction waste caused by inappropriate length of the guide rod frame.

[0023] Preferably, S5 and S6 are replaced together with the following steps:

[0024] S5', installing the hydraulic impact rock hammer into a standard section of the guide rod frame, and using a hydraulic cylinder to suspend the hydraulic impact rock hammer;

[0025] S6', hoist the standard section equipped with the hydraulic impact jack hammer into the rectangular frame structure and contact the guide roller, and pass one end of the traction rope on the hoist around the top of the main support and then fix it to the hanging ear at the bottom of the standard section equipped with the hydraulic impact jack hammer;

[0026] S7', sequentially hoist the other standard sections above the standard section with the hydraulic impact rock hammer, and fix them to the standard section below until a guide rod frame is formed, and then connect the relevant hydraulic oil pipes and cables to complete the installation of the rock drilling ship.

[0027] The use of segmented lifting guide rod frames makes the single lifting weight smaller and less difficult, which can reduce the difficulty of lifting.

[0028] Preferably, when the guide rod frame includes more than or equal to 3 standard sections, in step S7', the steps of hoisting other standard sections are:

[0029] S7'A, hoist the next standard section so that the next standard section is fixed on the top of the standard section equipped with the hydraulic impact rock hammer;

[0031] S7'C, hoist the next standard section so that the next standard section is fixed on the top of the current top standard section;

[0032] S7'D: When the standard section of the guide rod frame is not hoisted, repeat steps S7'B and S7'C until the guide rod frame is formed, and then connect the relevant hydraulic oil pipes and cables to complete the installation of the rock drilling vessel.

[0033] After hoisting the second standard section, the second standard section can be used as the basis to contact the guide roller, and then the installed standard section can be lowered as a whole to the top contact guide roller of the current top standard section through the winch, so that the height of the installed guide rod frame can be reduced, and the hoisting height of the next standard section can be lowered, which can reduce the difficulty of hoisting; and the height of the installed guide rod frame is low, and the center of gravity is low, which is conducive to the stability of the installation; and the guide rod frame is used subsequently to send the hydraulic impact rock hammer underwater, that is, the entire guide rod frame itself needs to be lowered, which can reduce the subsequent operation procedures and operation time.

[0034] Preferably, after completing the installation of the rock drilling vessel, the debugging phase begins. First, the guide rod frame is lifted up using a traction rope, and the traveling mechanism is debugged first to ensure that the traveling mechanism can operate safely and smoothly.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The present invention provides a method for installing a rock drilling vessel. By separately hoisting the structures of the traveling trolley, such as the track, chassis, traveling mechanism, winch, retractable bracket, and second-level platform, the hoisting weight and volume are reduced, making hoisting easier and safer. Furthermore, the prior installation provides a stable and balanced foundation for subsequent installation, making installation more efficient and safer and preventing overturning. Furthermore, the hydraulic impact jack hammer is pre-installed in the guide rod frame and hoisted as an integral unit, avoiding the difficulty of installing the hydraulic impact jack hammer after the guide rod frame is installed. This method makes the installation of heavy and complex rock drilling vessels simpler, more orderly, efficient, and safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] like Figure 4 and Figure 5 As shown, S4, the winch 33, the retractable bracket and the second-layer platform 35 are hoisted and installed on the walking chassis 32, so that the retractable bracket and the winch 33 are respectively located on the lateral sides of the ship 1, and the second-layer platform 35 is fixed on the walking chassis 32 and located above the winch 33; the retractable bracket includes a main bracket and a first guide stabilizing bracket 343, the bottom end of the main bracket is fixed to the walking chassis 32, and the top end of the main bracket extends away from the ship 1, one end of the first guide stabilizing bracket 343 is fixed to the main bracket, and the other end is arranged toward the outside of the ship 1, the first guide stabilizing bracket 343 is a rectangular frame structure, and a guide roller 38 is provided inside the rectangular frame structure; relevant equipment is provided on the second-layer platform 35; the winch 33 has a traction rope 36, and the traction rope 36 can be a wire rope, etc.

[0072] In one or more embodiments, the related equipment on the second-level platform 35 includes a generator set, an air compressor set, and a hydraulic power station;

[0073] In step S4, the winch 33, the retractable bracket and the second-layer platform 35 are installed in sequence, and then the relevant equipment on the second-layer platform 35 is hoisted onto the second-layer platform 35, which helps to reduce the difficulty of hoisting.

Figure 7-Figure 9 shown.

[0077] In one or more embodiments, after the installation of the drilling vessel is completed, the debugging phase begins. The guide rod frame 4 is first lifted using the traction rope 36, and the traveling mechanism 31 is first debugged to ensure that the traveling mechanism 31 can operate safely and smoothly.

[0078] In one or more embodiments, Figure 3 As shown, in step S3, a second fixed pulley 362 and a second guide and stabilizing bracket 37 are provided on the walking chassis 32.

[0082] In one or more embodiments, S5 and S6 are replaced together with the following steps:

[0083] S5', installing the hydraulic impact rock hammer 5 into a standard section of the guide rod frame 4, and using the hydraulic cylinder 51 to suspend the hydraulic impact rock hammer 5;

[0084] like Figure 10 As shown, S6', the standard section with the hydraulic impact rock hammer 5 installed is hoisted into the rectangular frame structure and contacts the guide roller 38, and one end of the traction rope 36 on the hoist 33 is passed around the top of the main bracket and fixed to the hanging ear 39 at the bottom of the standard section with the hydraulic impact rock hammer 5 installed; Figure 10It can be seen that the hydraulic impact rock hammer 5 is installed in the bottom standard section 41 and is suspended by the hydraulic cylinder 51; then the bottom standard section 41 and the hydraulic impact rock hammer 5 are hoisted together, and supported and limited by the guide rollers 38 inside the first guide and stabilizing bracket 343; when the second guide and stabilizing bracket 37 has been installed, the first guide and stabilizing bracket 343 and the guide rollers 38 inside the second guide and stabilizing bracket 37 are used together to perform circumferential guidance and limitation, so that the traction rope 36 on the winch 33 can pull the guide rod frame 4 upward, and the guide rollers 38 inside the first guide and stabilizing bracket 343 are used to ensure the verticality of the guide rod frame 4, and in the process of pulling up or lowering the traction rope 36 on the winch 33, the guide rollers 38 can not only ensure the verticality of the guide rod frame 4, but also roll on the guide rod frame 4, avoiding excessive friction between the first guide and stabilizing bracket 343 and the guide rod frame 4.

[0085] like Figure 11 and Figure 12 As shown, S7', the other standard sections above the standard section with the hydraulic impact rock hammer 5 are hoisted in sequence and fixed with the standard section below until a guide rod frame 4 is formed, and then the relevant hydraulic oil pipes 52 and cables are connected to complete the installation of the rock drilling ship. Figure 11 In the process, the second standard section 42 is installed on the top of the bottom standard section 41. Figure 12 In the embodiment, the third standard section 43 is installed on the top of the second standard section 42. The guide rod frame 4 is hoisted in sections, so that the weight of a single hoisting is small, the difficulty is small, and the difficulty of hoisting can be reduced.

[0086] In one or more embodiments, when the guide rod frame 4 includes more than or equal to 3 standard sections, in step S7', the steps of hoisting other standard sections are:

[0087] S7'A, hoist the next standard section so that the next standard section is fixed on the top of the standard section where the hydraulic impact rock hammer 5 is installed; Figure 11 As shown, the second standard section 42 is hoisted on top of the bottom standard section 41;

[0088] S7'B, lower the installed standard section as a whole to the top of the current top standard section by the winch 33 to contact the guide roller 38; Figure 13 As shown, the bottom standard section 41 and the second standard section 42 are lowered as a whole by the winch 33 until the top of the second standard section 42 contacts the guide roller 38, and the guide roller 38 is used to limit the position to ensure verticality and safety;

[0089] S7'C, hoist the next standard section so that the next standard section is fixed on the top of the current top standard section; Figure 14 As shown, the third standard section 43 is hoisted on top of the lowered second standard section 42. If there are only three standard sections, the hoisting is completed.

[0090] S7'D: When the standard section of the guide rod frame 4 is not hoisted, repeat steps S7'B and S7'C until the guide rod frame 4 is formed, and then connect the relevant hydraulic oil pipes 52 and cables to complete the installation of the rock drilling vessel.

[0091] After the second standard section 42 is hoisted, the second standard section 42 can be used as the basis to contact the guide roller 38, and then the installed standard section can be lowered as a whole to the top contact guide roller 38 of the current top standard section through the winch 33, so that the height of the installed guide rod frame 4 can be reduced, so that the hoisting height of the next standard section can be lowered, which can reduce the difficulty of hoisting; and the height of the installed guide rod frame 4 is low, and the center of gravity is low, which is conducive to the stability of the installation; and the guide rod frame 4 is subsequently used to send the hydraulic impact rock hammer 5 underwater, that is, the entire guide rod frame 4 itself needs to be lowered, such as Figure 15 As shown, the subsequent working steps and working time can be reduced.

[0092] In this embodiment, a method for installing a rock drilling vessel is provided, which comprises welding a track 2 on the main deck 11 of the vessel 1 to provide a foundation for the installation of a traveling mechanism 31; after the installation of the traveling mechanism 31 is completed, the traveling mechanism 31 is fixed on the track 2 to provide stable installation conditions for the traveling chassis 32; after the traveling chassis 32 is installed, the traveling chassis 32, the traveling mechanism 31 and the track 2 form a whole, which can be balanced and prevent overturning; then, based on the traveling chassis 32, a winch 33, a retractable bracket and a second-layer platform 35 are hoisted and installed on the traveling chassis 32, so that the retractable bracket and the winch 33 are respectively located on both sides of the vessel 1, and the second-layer platform 35 is fixed on the traveling chassis 32 and located above the winch 33, so that the vessel 1 is more stable, and the installation of the main bracket of the retractable bracket, the first guide stabilizing bracket 343 and the guide roller 38 and the winch 33 provides a foundation for the subsequent hoisting of the guide rod frame 4 and the hydraulic impact rock hammer 5 as a whole.

[0093] The installation method of the rock drilling ship of the embodiment is characterized in that the structures belonging to the walking trolley, such as the track 2, the chassis, the walking mechanism 31, the winch 33, the retractable support and the second floor 35, are hoisted separately, so that the hoisting weight and volume are small, and the hoisting is easier and safer; the first installation provides a stable and balanced installation basis for the later installation, so that the installation is more efficient and safe, and the overturning problem can be avoided; the hydraulic percussion rock hammer 5 is installed in the guide rod frame 4 in advance and hoisted integrally, so that the problem that it is difficult to install the hydraulic percussion rock hammer 5 after the guide rod frame 4 is installed is avoided. The rock drilling ship with large weight and complex structure is installed more simply, orderly, efficiently and safely. The guide rod frame 4 is hoisted in sections, so that the hoisting difficulty is smaller and safer; during the sectional hoisting process, after the second standard section 42 is hoisted, the hoisted standard section can be lowered by using the traction rope 36 of the winch 33 of the trolley, so that the hoisting height of the subsequent standard section is reduced, the hoisting difficulty is lower; and the hoisting height of the standard section is reduced, that is, the final installation height of the guide frame is reduced, so that the subsequent rock drilling operation process can be reduced, and the use efficiency is improved.

[0094] The present embodiment provides an installation method for a rock drilling vessel. After the rock drilling vessel is installed, the traveling mechanism 31, the traveling chassis 32, the winch 33, the retractable bracket, the second-layer platform 35, the second fixed pulley 362, the third fixed pulley 363, and the second guide stabilizing bracket 37 can be moved along the track 2 as a whole trolley to change the horizontal position of the guide rod frame 4. The winch 33 can lower the guide rod frame 4 so that the bottom standard section 41 provided with the hydraulic impact rock drilling hammer 5 is located at the rock surface. The hydraulic impact rock drilling hammer 5 includes a waterproof shell, a hydraulic impact hammer, a replacement device and a drill rod. The waterproof shell is suspended inside the bottom standard section 41 of the guide rod frame 4 through a hydraulic oil cylinder 51. The drill rod is connected to the lower end of the waterproof shell through the replacement device. The hydraulic impact hammer is arranged inside the waterproof shell. The hydraulic impact hammer includes a hammer core and a hydraulic cylinder. The pressure cylinder can lift the hammer core; when the hydraulic cylinder does not act on the hammer core, the hammer core performs free fall motion inside the waterproof housing under the action of its own gravity, and impacts the substitute hitting device, which acts on the drill rod, and the drill rod hits the underwater rock formation. Under the reaction force of the rock formation, the hydraulic oil cylinder 51 inside the guide rod frame 4 for hanging the hydraulic impact rock hammer 5 no longer provides a lifting force for the hydraulic impact rock hammer 5, so that the entire hydraulic impact rock hammer 5 falls and the drill rod enters the rock formation. Because the impact energy of the entire hydraulic impact hammer is carried out in the closed environment inside the waterproof housing, its impact energy will not be consumed by water, thereby shortening the falling stroke of the entire hydraulic impact rock hammer 5, which can improve construction efficiency, and the hydraulic impact rock hammer 5 will not be towed by the traction rope 36, so the loss of the traction rope 36 during the rock drilling process can be eliminated. The striking energy of the hydraulic impact hammer is transferred to the drill rod through the replacement device (due to the small diameter of the hammer head, if the drill rod is directly hit, if there is a small angle of inclination, it is easy to cause structural damage. Therefore, the striking energy is transmitted through the replacement device). The drill rod resists and impacts the rock surface to achieve the function of breaking the rock. In order to enable the hydraulic impact hammer to operate normally underwater, a waterproof shell is set outside the hydraulic impact hammer. Compressed air is injected into the waterproof shell through the compressed air inlet valve. The compressed air is used to maintain the working environment of the hydraulic impact hammer in a dry environment. An upper shock absorber and a lower shock absorber are also provided at the connection between the replacement device and the drill rod. The upper and lower shock absorbers are mainly used to absorb and eliminate the residual energy of a single blow of the hydraulic impact hammer to ensure that the equipment is not damaged.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
