Description

Technical Field

[0001] The 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] At present, the underwater rock excavation mainly adopts the controlled blasting technology or the impact rock hammer technology. When approaching buildings (structures), especially in narrow waters in inland rivers, near embankments, bridges, subway structures, etc., in order to avoid affecting their structural safety, rock drilling rods are usually used to drill rocks. The rock drilling rods are lifted to a certain height to convert their gravitational potential energy into impact on the rock. Because when drilling in water, the energy of the rock drilling rod is greatly weakened as the water depth increases during the falling process of the rock drilling rod, which requires the rock drilling rod to be lifted to a higher height. In addition, the lifting speed of the rock drilling rod is slow and the work efficiency is low when lifting the rock drilling rod in water. In addition, the traction rope will rub repeatedly during the lifting process of the rock drilling rod, resulting in frequent replacement and high cost.

[0003] In order to solve the above problems, the inventor of the present application proposed a rock drilling vessel, which stably delivers the hydraulic impact rock hammer to the underwater rock surface and ensures the stability of the vertical movement of the hydraulic impact rock hammer, so that the hydraulic impact rock hammer can drill underwater, and the lifting stroke of the hydraulic impact rock hammer during the rock drilling process is short, which can improve construction efficiency and reduce the loss of the traction rope; but this rock drilling vessel has a complex structure and a large weight, 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 of the rock drilling vessel, such as the 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 arranged longitudinally along the main deck on the main deck of the ship;

[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 the running mechanism can move and be 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, the retractable bracket and the second-layer platform on the traveling 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 traveling chassis and located above the winch; the retractable bracket includes a main bracket and a first guide stabilizing bracket, the bottom end of the main bracket is fixed to the traveling chassis, the top end of the main bracket extends away from the ship, one end of the first guide stabilizing bracket is fixed to the main bracket, and the other end is arranged toward the outside of the ship, the first guide stabilizing bracket is a rectangular frame structure, and a guide roller is arranged inside the rectangular frame structure; the second-layer platform is provided with relevant equipment;

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

[0011] S6. Lift the guide rod frame and hydraulic impact rock hammer as a whole into the rectangular frame structure and contact the guide roller, and pass one end of the traction rope on the winch around the top of the main bracket and fix it on the hanging ear at the bottom of the guide rod frame, connect the relevant hydraulic oil pipes and cables, and complete the installation of the rock drilling ship.

[0012] In this scheme, a track is first welded on the main deck of the ship to provide an installation foundation 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 form a balance 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 structures of the traveling trolley, such as the track, chassis, traveling mechanism, winch, retractable bracket and second-layer platform, so that the hoisting weight and volume are small, and the hoisting is easier and safer; and the first installation provides a stable and balanced installation foundation for the later installation, making the installation more efficient and safe, and avoiding the overturning problem. In addition, the hydraulic impact rock hammer is installed in the guide rod frame in advance and hoisted as a whole, avoiding the problem of difficulty in installing the hydraulic impact rock hammer after the guide rod frame is installed. It makes the installation of the heavy and complex rock drilling ship simpler, more orderly, 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 clearance between the traveling wheel sets of the traveling mechanisms and the tracks is adjusted, and after ensuring that the four traveling mechanisms will not be twisted, the traveling chassis is welded and fixed to the four traveling mechanisms to ensure the installation quality of the traveling mechanisms.

[0019] Preferably, the related 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-layer platform are installed in sequence, and then the relevant equipment on the second-layer platform is hoisted onto the second-layer 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:

[0025] S6', hoist the standard section with the hydraulic impact rock hammer installed into the rectangular frame structure and contact the guide roller, and 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 standard section with the hydraulic impact rock hammer installed;

[0026] S7', sequentially hoist other standard sections above the standard section with the hydraulic impact rock hammer, and fix them with the lower standard section 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 weight of a single lift smaller and less difficult, thus reducing 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 lower, 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 the installation of the rock drilling vessel is completed, the debugging phase is entered, the guide rod frame is first lifted up using a traction rope, and the traveling mechanism is first debugged to ensure that the traveling mechanism can operate safely and smoothly.

[0040] The present invention provides an installation method for a rock drilling vessel, which separates and hoists structures belonging to a traveling trolley such as a track, a chassis, a traveling mechanism, a winch, a retractable bracket, and a second-layer platform, so that the hoisting weight and volume are small, and the hoisting is easier and safer; and the prior installation provides a stable and balanced installation foundation for the subsequent installation, so that the installation is more efficient and safe, and the overturning problem can be avoided. Moreover, the hydraulic impact rock hammer is installed in advance in the guide rod frame and hoisted as a whole, so that the problem of difficulty in installing the hydraulic impact rock hammer after the guide rod frame is installed is avoided.

[0092] In the present embodiment, a method for installing a rock drilling vessel is provided, firstly, a track 2 is welded on the main deck 11 of the ship 1 to provide an installation foundation for the installation of the 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 a stable installation condition 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 form a balance 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 the lateral sides of the ship 1, and the second-layer platform 35 is fixed on the traveling chassis 32 and located above the winch 33, so that the ship 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 basis for the subsequent overall hoisting of the guide rod frame 4 and the hydraulic impact rock hammer 5.

[0093] The installation method for a rock drilling vessel of the present embodiment is to separate and hoist the structures belonging to the traveling trolley, such as the track 2, chassis, traveling mechanism 31, winch 33, retractable bracket and second-layer platform 35, so that the hoisting weight and volume are small, and the hoisting is easier and safer; and the prior installation provides a stable and balanced installation foundation for the subsequent installation, so that the installation is more efficient and safe, and the overturning problem can be avoided. Moreover, the hydraulic impact rock hammer 5 is installed in the guide rod frame 4 in advance and hoisted as a whole, so that the problem of difficulty in installing the hydraulic impact rock hammer 5 after the guide rod frame 4 is installed is avoided. It makes the installation of the heavy and complex rock drilling vessel simpler, more orderly, more efficient and safer. The guide rod frame 4 is hoisted in sections, which makes the hoisting easier and safer. In the process of hoisting in sections, after the second standard section 42 is hoisted, the traction rope 36 of the hoisting machine 33 of the trolley can be used to lower the hoisted standard section, thereby reducing the hoisting height of the subsequent standard sections and making the hoisting easier. Lowering the hoisting height of the standard sections, that is, lowering the final installation height of the guide frame, can reduce the subsequent rock drilling operation procedures and improve the use efficiency.

[0094] The present embodiment is a method for installing a rock drilling vessel. After the rock drilling vessel is installed, the traveling mechanism 31, the traveling chassis 32, the winch 33, the retracting bracket, the second-layer platform 35, the second fixed pulley 362, the third fixed pulley 363, and the second guide stabilizing bracket 37 can move along the track 2 as a whole trolley to change the horizontal position of the guide rod frame 4, and the guide rod frame 4 can be lowered by the winch 33 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 replacement 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 on the inner side of the guide rod frame 4 for hanging the hydraulic impact rock hammer 5 no longer provides a hanging 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 of 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 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 transmitted 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, so 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, and compressed air is injected into the waterproof shell through the compressed air inlet valve. Compressed air is used to keep the working environment of the hydraulic impact hammer in a dry environment. An upper shock absorbing device and a lower shock absorbing device are also provided at the connection between the replacement device and the drill rod. The upper shock absorbing device and the lower shock absorbing device are mainly used to absorb and eliminate the residual energy of a single hit of the hydraulic impact hammer to ensure that the equipment will not be 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 protection scope of the present invention.
