Description

Technical Field

[0001] This invention relates to the field of waterway dredging, especially inland waterway dredging, and particularly to a rock excavation vessel. Background Technology

[0002] Underwater rock excavation has always been a challenging aspect of dredging projects. Comparing several major construction techniques, underwater controlled blasting is the most efficient, but it causes significant damage to the surrounding ecological environment. With increasing environmental awareness, blasting is now prohibited in most construction projects. Large cutter suction dredgers are another viable option for underwater rock excavation. The combination of a heavy-duty cutter head bridge and a high-powered cutter excavation system ensures high output, but heavy equipment like large cutter suction dredgers is difficult to deploy in water-deep environments such as inland waterway lock construction. Heavy-duty backhoe dredgers perform well with softer rocks, but their efficiency is less than ideal when dealing with hard rocks such as bedrock. Hydraulic breakers and impact hammers also have relatively low efficiency. Summary of the Invention

[0018] The technical solution proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0019] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the terms “at least two” or “more than” are generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature. Additionally, as used in this invention, “installed,” “connected,” “linked,” and “set” on one element from another should be interpreted broadly, generally indicating only a connection, coupling, mating, or transmission relationship between the two elements, which can be direct or indirect through an intermediate element. This connection, coupling, mating, or transmission should not be construed as indicating or implying a spatial positional relationship between the two elements, i.e., one element can be located arbitrarily inside, outside, above, below, or to one side of another element, unless otherwise explicitly stated. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. Furthermore, directional terms such as above, below, up, down, upward, downward, left, right, etc., are used relative to exemplary embodiments as shown in the figures, with upward or up direction pointing towards the top of the corresponding figure, and downward or down direction pointing towards the bottom of the corresponding figure.

[0020] like Figures 1 to 4As shown, this embodiment provides a rock excavation vessel, including an excavator slewing platform 16 mounted on the hull. An adjustable integrated boom is hinged to the excavator slewing platform 16, and a milling head 1 is connected to the working end of the integrated boom. In operation, the milling head 1 operates underwater, crushing underwater rocks. To prevent the crushed rocks from being washed away by water, which would hinder rock collection, an underwater pump 2 and an underwater pump motor 3 driving the underwater pump 2 are installed on the integrated boom near the milling head 1. The pump inlet of the underwater pump 3 corresponds to the position of the milling head 1. Through the suction of the underwater pump 3, the crushed rocks from the milling head 1 can be immediately pumped out, improving rock collection efficiency. The milling heads 1 are configured in pairs for rotating operation. Figure 1 Looking at the center, it rotates clockwise. Additionally, different milling heads are used for rocks of varying hardness. Milling head 1 is an outsourced component. Furthermore, different specifications of underwater pumps 2 can be configured according to the cutting efficiency of milling head 1 and the size of the rock particles. Underwater pump 2 is a direct-drive, single-shell pump. A base for fixing underwater pump 2 is installed on the integrated boom. Underwater pump motor 3 directly drives underwater pump 2; a cable is installed between the two, and the integrated boom has a support for mounting underwater pump motor 3.

[0021] The integrated boom includes a digging arm 8 as the main digging boom. One end of the digging arm 8 is hinged to the excavator slewing platform 16, and the other end is hinged to a digging arm 4. One end of the digging arm 4 is connected to the milling head 1. The digging arm 8 is used to achieve different digging depths and control the digging distance. The digging arm 4 can flexibly rotate the front end of the integrated boom to adjust the dredging angle.

[0022] Specifically, the first excavator arm 8 is controlled by the first hydraulic cylinder 9 to adjust its swing amplitude, which in turn changes its digging depth; the second excavator arm 4 is controlled by the second hydraulic cylinder 7 to adjust its dredging angle and ground pressure. The two excavator arms are controlled by different hydraulic cylinders, allowing for independent angle adjustment and further increasing the digging angle range of the integrated boom. Preferably, one end of the first hydraulic cylinder 9 is hinged to the excavator's slewing platform 16, and the other end is connected to the first excavator arm 8; optimally, it is connected to the first excavator arm 8 at a slightly upper position. One end of the second hydraulic cylinder 7 is connected to the first excavator arm 8, and the other end is connected to the second excavator arm 4.

[0023] The outlet end of the underwater pump 3 is connected to a gravel conveying pipeline, and the outlet end of the gravel conveying pipeline corresponds to the transfer pool 10 set on the hull. The pumped gravel is transported to the transfer pool 10 through the gravel conveying pipeline. The transfer pool 10 provides temporary storage space for the gravel. The transfer pool 10 is set at the bow of the hull and is used for short-term storage of the gravel pumped out by the underwater pump. The transfer pool 10 is wide-mouthed with a gravel inlet at the top and a gravel outlet at the bottom. A gravel conveying station is set at the bottom of the gravel outlet to transport the gravel to a designated location. In order to facilitate the entry of gravel into the transfer pool 10, the bulkhead of the transfer pool 10 near the bow and stern is inclined at 45° to maximize the capacity of the transfer pool 10. The bulkhead of the transfer pool 10 near the excavator slewing platform 16 is inclined at 30° to reduce the height of the gravel inlet and facilitate the transfer of gravel.

[0024] The crushed stone conveying pipeline includes a flexible hose 5 connected at one end to the output end of the underwater pump 2. The position of the flexible hose 5 corresponds to the hinge point of the excavator arm 8 and the excavator arm 4. The flexible hose 5 facilitates the relative swinging motion of the excavator arm 8 and the excavator arm 4. The other end of the flexible hose 5 is connected to a rigid pipe 6, the other end of which extends to a position near the excavator's slewing platform 16, and then connects to the transfer pool 10 through a transition pipe. Preferably, the transition pipe between the rigid pipe 6 and the transfer pool 10 is also a combination of flexible and rigid pipes. The flexible hose is located at the hinge point of the excavator arm 8 and the excavator's slewing platform 16, and the rigid pipe connected to the flexible hose points to the crushed stone inlet of the transfer pool 10. After the crushed stone is pumped in by the underwater pump 2, it enters the transfer pool 10 in sequence through the flexible hose 5, the rigid pipe 6, and the transition pipe. The flexible hose 5 is armored to prevent wear. Both the flexible hose 5 and the rigid pipe 6 are hinged to the integrated boom.

[0025] The crushed stone transport station includes a longitudinal belt conveyor 11 located at the bottom of the transfer pool 10, corresponding to the crushed stone outlet. This conveyor transports the crushed stone along the length of the transfer and serves as a transition, transporting the crushed stone to a transverse belt conveyor 13 located at the far end of the longitudinal belt conveyor 11. The transverse belt conveyor 13 is used to transport the crushed stone to the barge and is equipped with rollers at the bottom, allowing it to move laterally. Here, "lateral" refers to the direction perpendicular to the length of the barge hull.

[0026] In this embodiment, a set of main positioning piles 15 is included. The main positioning piles 15 are raised and lowered by a winch and pulleys, and tilted by a main positioning pile cylinder 14, which longitudinally deflects the main positioning piles 15. Auxiliary positioning piles 12 are also included, preferably two sets arranged symmetrically on the port and starboard sides. The auxiliary positioning piles 12 are raised and lowered by a winch and pulleys, and only have raising, lowering, and positioning functions. The main and auxiliary piles work together to achieve longitudinal movement of the ship.
