Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of cutter suction dredgers, and more particularly relates to a deep-water environmentally friendly cutter suction dredger which has a large dredging depth and can be disassembled and assembled. Background Art
[0002] In the field of dredging engineering, large dredgers are core equipment, and their operating efficiency and structural rationality directly determine the project cost and cycle. With the increase of excavation depth and power demand, the length of the key component of the dredger, the bridge, has increased significantly, reaching the level of 35 meters. The main functions of the bridge are the twisting part and the mud suction part. Such super-long bridges face many technical bottlenecks in the land transportation link, which has become a key issue restricting the efficiency of equipment deployment.
[0003] Among them, traditional road transport regulations have strict restrictions on oversized cargo (length > 30 meters), which requires special approval procedures and dedicated transportation equipment; for 35-meter bridges, multi-axle hydraulic flatbed trucks must be used for transportation, but there are the following challenges: poor road adaptability: the route must be surveyed in advance to avoid height-restricted bridges and sharp bends, which severely limits the choice of transportation routes; long bridges are prone to resonance due to bumps and vibrations during transportation, which may cause structural deformation; in a certain engineering case, the deflection of an unreinforced 30-meter bridge was found to exceed the standard by 30% after transportation, and it needed to be returned to the factory for correction; oversized transportation requires coordination with multiple departments such as transportation and urban management, which increases the time consumption of single transportation approval and the transportation cost is higher than that of standard goods.
[0004] For cargo transportation less than 30 meters, the approval procedures for those exceeding 30 meters are different from those for those not exceeding 30 meters, which reduces transportation costs and has stronger adaptability to roads than bridges over 30 meters. Summary of the Invention

[0024] The embodiment of the present invention is intended to introduce and illustrate the structural composition of a deep-water environmentally friendly detachable suction dredger with a large dredging depth and the coordination relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the deep-water environmentally friendly suction dredger with a large dredging depth and a detachable suction dredger in the embodiment of the present invention can be selected according to the specific situation and are not specifically limited or explained here.
[0025] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
[0026] Example 1 See also Figure 1-8 As shown, a deep-water environmentally friendly cutter suction dredger with a large dredging depth and detachable assembly includes a hull structure 1, which includes a hull front end 11 and a hull rear end 12; the length of the hull rear end 12 is less than 30M.
[0027] See also Figure 1-8As shown, a positioning device 2 is provided on the side of the rear end 12 of the hull away from the front end 11 of the hull, and the positioning device 2 includes two positioning columns 21. The axes of the positioning columns 21 are vertically arranged, and the two positioning columns 21 are in the same horizontal plane. Positioning holes 22 are opened at the positions of the two positioning columns 21 at the rear end 12 of the hull, and the positioning holes 22 are coaxially arranged with the positioning columns 21; the positioning columns 21 can be slidably connected in the positioning holes 22 along the axial direction of the positioning columns 21; a driving motor is provided at the position of the positioning columns 21 at the rear end 12 of the hull; and a transverse anchor 23 is provided at the front end 11 of the hull.
[0028] During use, after the hull structure 1 reaches the specified position, the positioning column 21 is lowered by driving the motor to achieve the positioning effect of the hull structure 1. The positioning column 21 adopts a double-column synchronous lifting system and is hydraulically driven to penetrate 30 meters into the riverbed / seabed to form a stable fulcrum with large pull-out resistance; it forms a triangular stable structure with the hull structure 1 and the transverse anchor 23, which can resist the impact of water flow and reduce the hull displacement during operation.
[0029] See also Figure 1-8 As shown, a makeshift groove 24 is opened on the side of the rear end 12 of the hull close to the front end 11 of the hull. The opening direction of the makeshift groove 24 is the same as the length direction of the rear end 12 of the hull, and the opening direction of the makeshift groove 24 is toward the front end 11 of the hull. A mud suction pipe 25 is set in the makeshift groove 24, and a mud suction pump 26 is set at the position of the mud suction pipe 25 corresponding to the rear end 12 of the hull. The mud suction pump 26 is connected to the mud suction pipe 25, and one end of the mud suction pipe 25 is set corresponding to the outside of the hull structure 1.
[0030] See also Figure 1-8 As shown, a clamping device 3 is provided at one end of the rear end 12 of the hull and the front end 11 of the hull that is close to each other; the clamping device 3 includes two embedded blocks 31, and the two embedded blocks 31 are arranged on both sides of the front end 11 of the hull. Two embedded grooves 32 are provided at positions of the rear end 12 of the hull corresponding to the two embedded blocks 31, and the embedded blocks 31 can be inserted into the embedded grooves 32; clamping grooves 33 are provided on both sides of each embedded block 31 of the front end 11 of the hull, and clamping blocks 35 are provided at positions of the rear end 12 of the hull corresponding to the four clamping grooves 33, and the clamping blocks 35 can be inserted into the clamping grooves 33.
[0031] See also Figure 1-8When the locking cam 35 is fully inserted into the locking cam 33, the locking cam 35 and the locking cam 31 are not fully inserted into the locking cam 33 and the locking cam 31 is not fully inserted into the locking cam 33. Above the slot 33; a positioning block 411 is provided at the position of the positioning plate 42 corresponding to the positioning slot 41. The cross-section of the positioning block 411 is an isosceles triangle. The bottom edge of the positioning block 411 is arranged close to the positioning plate 42. The isosceles angle of the positioning block 411 is 45°. The positioning slot 41 corresponds to the position of the positioning block 411 and is provided with a positioning inclined surface, and the positioning block 411 can be inserted into the positioning slot 41; the distance between the embedded block 31 and the upper surface of the front end 11 of the hull is the same as the thickness of the positioning plate 42, and the distance between the positioning block 411 and the upper surface of the front end 11 of the hull is the same as the thickness of the positioning plate 42; the length of the positioning plate 42 is the same as the difference between the embedded block 31 and the embedded slot 32, and the length of the positioning plate 42 is the same as the difference between the clamping block 35 and the clamping slot 33. The end of the positioning plate 42 can abut against the front end 11 of the hull, and the end of the positioning plate 42 can abut against the rear end 12 of the hull.
[0032] See also Figure 1-8 As shown, locking plates 43 are provided on both sides of the positioning block 411 corresponding to the lower surface of the positioning plate 42. The locking plates 43 are tilted, and the starting point of the locking plates 43 is close to the positioning block 411. The two locking plates 43 tend to tilt downward toward the side away from the positioning plate 42, and the maximum angle between the locking plates 43 and the positioning plates 42 does not exceed 45°; in this embodiment, the angle between the locking plates 43 and the positioning plates 42 is 30°; locking grooves 44 are provided at the positions of the locking plates 43 corresponding to the rear end 12 and the front end 11 of the hull, and the locking plates 43 can be inserted into the locking grooves 44.
[0033] When in use, the front end 11 of the hull and the rear end 12 of the hull are aligned along the length direction of the hull structure 1, and then the front end 11 of the hull is moved and slowly translated along the length direction of the hull structure 1 to the alignment position of the rear end 12 of the hull to ensure that the axis of the front embedded block 31 coincides with the axis of the rear embedded groove 32; the staff calibrates the end face gap of the front end 11 and the rear end 12 of the hull through a laser rangefinder to meet the docking tolerance requirements; the staff pushes the front end 11 of the hull to push the embedded block 31 into the embedded groove 32, and the clamping block 35 into the clamping groove 33. When the end of the clamping block 35 contacts the clamping groove 33 and the end of the embedded block 31 contacts the embedded groove 32, the identification method is: when a slight metal collision sound is heard or the sound is greater than 1.2 times the pushing force and there is no feed amount at the front end 11 of the hull, the propulsion is stopped immediately.
[0034] At this time, the staff operates the lifting mechanism to push the positioning plate 42 downward so that the positioning block 411 can be locked in the fixed position in the vertical direction. The locking plate 43 can be inserted into the locking groove 44 in the positioning groove 41, and the upper surface of the positioning plate 42 is at the same horizontal plane as the upper surfaces of the front end 11 of the hull and the rear end 12 of the hull. Due to the weight of the positioning plate 42, the mutual contact between the positioning plate 42 and the front end 11 of the hull and the rear end 12 of the hull, and the fixation of the relative positions of the front end 11 of the hull and the rear end 12 of the hull, a self-locking function is achieved. The vertical force of the hull structure 1 is counteracted by the interaction force between the embedded block 31 and the embedded groove 32, the clamping block 35 and the clamping groove 33, the locking groove 44 and the locking plate 43; the longitudinal force of the hull structure 1 is counteracted by the gravity of the positioning plate 42, the positioning block 411, the locking plate 43 and the interaction force between the locking plate 43 and the locking groove 44; the self-locking function of the front end 11 of the hull and the rear end 12 of the hull is achieved.
[0035] See also Figure 1-8As shown, a locking groove 45 is provided at one end of the rear end 12 of the hull near the positioning plate 42, and a locking groove 45 is provided at one end of the front end 11 of the hull near the positioning plate 42, and the axis of the locking groove 45 is arranged horizontally; a locking hole 451 is provided at the position of the positioning plate 42 corresponding to the locking groove 45, and the locking hole 451 is arranged coaxially with the locking groove 45; a locking rod 46 is slidably connected in the locking groove 45, and the end of the locking rod 46 can be inserted into the locking hole 451, and one end of the locking rod 46 can extend out of the locking groove 45; a first locking groove 461 and a second locking groove 462 are provided on the locking rod 46, and the first locking groove 461 and the second locking groove 462 are connected to each other, and the first locking groove 461 and the second locking groove 462 are connected to each other. On the side of the connecting part close to the positioning plate 42, the first locking groove 461 is an arc-shaped groove, and the second locking groove 462 is a straight groove. The opening direction of the second locking groove 462 is the same as the length direction of the locking rod, and the distance that the locking rod 46 extends out of the locking groove 45 is the same as the projection length of the vertical length of the first locking groove 461; the locking groove 45 is provided with a locking block 463 at a position corresponding to the first locking groove 461, and the locking block 463 slides along the first locking groove 461 into the second locking groove 462; the locking groove 45 is provided with a spring 47 at a position corresponding to the locking rod 46, and the spring 47 is coaxially arranged with the locking rod 46, one end of the spring 47 is fixedly connected to the locking rod 46, and the other end of the spring 47 is fixedly connected to the locking groove 45.
[0036] When in use, the locking rods 46 of the front end 11 of the hull and the rear end 12 of the hull extend out of the locking grooves 45; when the positioning plate 42 is close to the front end 11 of the hull and the rear end 12 of the hull, the end of the positioning rod and one end of the locking rod 46 abut against each other, pushing the locking rod 46 to slide in the direction away from the positioning plate 42, and at the same time compressing the spring 47. The first locking groove 461 provided on the locking rod 46 is an arc groove, and the locking rod 46 slides in the horizontal direction. At the same time, due to the sliding of the locking block 463 in the first locking groove 461, the locking rod 46 is driven to rotate; when the locking rod 46 is fully inserted into the locking groove 45, the locking block 463 slides from the first locking groove 461 to the second locking groove 4 62; the positioning plate 42 continues to move downward, and when the locking hole 451 and the locking groove 45 are on the same axis, the spring 47 releases its elastic properties, pushing the locking rod 46 to slide in the direction close to the positioning plate 42 until the end of the locking rod 46 is inserted into the locking hole 451; because the first locking groove 461 is an arc groove, except for the force of the locking rod rotating plus the horizontal force of the locking rod, the movement of the locking block 463 sliding from the first locking groove 461 to the second locking groove 462 is irreversible; in working conditions, the locking rod cannot receive the force of rotation along the axis of the locking rod, thereby realizing automatic locking of the positioning plate 42 and the front end 11 and the rear end 12 of the hull.
[0037] See also Figure 1-8As shown, mounting frames 51 are provided on both sides of the corresponding give-way groove 24 at the rear end 12 of the hull. The mounting frames 51 include a base 52 and a mounting column 53. The base 52 is arranged horizontally, and the mounting column 53 is fixedly connected to the side of the base 52 away from the front end 11 of the hull. The base 52 and the mounting column 53 are integrally formed; the axis of the mounting column 53 is arranged vertically.
[0038] See also Figure 1-8 As shown, a gantry 54 is provided on the front end 11 of the hull, and a mud twisting system 55 is provided on the gantry 54. One end of the mud twisting system 55 is rotatably connected to the front end 11 of the hull, and the mud twisting system 55 can be interconnected with the mud suction pipe 25; tilting rods 56 are fixedly connected to both ends of the gantry 54, and the starting points of the tilting rods 56 are set on both sides of the gantry 54. The tilting rods 56 are tilted toward the side away from the gantry 54, and the tilting angle of the tilting rod 56 is 30°. A baffle 57 is provided at the position of the mounting column 53 corresponding to the tilting rod 56, and the baffle 57 is rotatably connected to the mounting column 53; when the baffle 57 contacts the tilting rod 56, the tilting angle of the baffle 57 is the same as the tilting angle of the tilting rod 56, and the width of the baffle 57 is greater than the width of the tilting rod 56.
[0039] When in use, the tilting rod 56 and the mounting column 53 play a key role in the triangular stabilization structure; the tilting rod 56 forms a stable triangular support by connecting the gantry 54 at the front end 11 of the hull and the mounting column 53 at the rear end; this design increases lateral support, can disperse the shear stress on the main load-bearing components, and reduce bending deformation; at the same time, the rotating connection between the tilting rod 56 and the mounting column 53 allows adjustment during transportation and installation, thereby improving the flexibility of the hull structure 1; when subjected to force, the tilting rod 56 decomposes the external force into a component force along the axial direction of the tilting rod 56, and transmits it to the rear end 12 of the hull through the triangular structure, forming a stable support.
[0040] The self-locking function is achieved through the gravity of the positioning plate 42 and the locking plate 43; the design of the positioning block 411 and the positioning slot 41 allows the positioning block 411 to generate a horizontal component force during the insertion process to push the front end 11 of the hull to move slightly until it is completely embedded in the positioning slot 41; as the positioning block 411 is inserted, the locking plate 43 automatically slides into the locking slot 44 under the action of gravity, forming a self-locking mechanism; this self-locking mechanism uses friction to resist external interference and ensure the stable connection between the front end 11 of the hull and the rear end 12 of the hull; the realization of self-locking depends on the geometric shape of the positioning plate 42 and the locking plate 43 and the friction coefficient between the materials, and can maintain a stable state without the need for external energy.
[0041] In summary, the deep-water, detachable, environmentally friendly cutter suction dredger with a large dredging depth ensures the operational stability of the equipment in complex water environments from a principle level through the triangular stable structure formed by the tilting rod 56, the mounting column 53 and the hull; this design utilizes the geometric uniqueness and force characteristics of the triangle, combined with the self-locking function, to achieve efficient force transmission and stable support.
[0042] Example 2 See also Figure 1-10 As shown, as another embodiment, the difference from Example 1 is that the locking plate 43 is an arc-shaped plate, and the arc direction of the locking plate 43 is set in the direction away from the positioning plate 42. The maximum angle between the line connecting the starting point of the locking plate 43 and the end point of the locking plate 43 and the positioning plate 42 does not exceed 75°. The angle of the line connecting the starting point of the locking plate 43 and the end point of the locking plate 43 is proportional to the length of the locking plate 43. The arc angle of the locking plate 43 is a smooth curve. In this embodiment, the line connecting the starting point of the locking plate 43 and the end point of the locking plate 43 is 45°. The rear end 12 of the hull and the front end 11 of the hull are provided with locking grooves 44 at the positions corresponding to the locking plates 43, and the locking plates 43 can be inserted into the locking grooves 44.
[0043] Effects of this embodiment: The arc-shaped locking plate 43 changes the force transmission path by optimizing its geometric shape. Compared with the flat locking plate 43, the curved shape of the arc-shaped locking plate 43 disperses the external force along the arc surface, reducing stress concentration and thus improving the overall stability of the structure. In addition, the arc-shaped design has kinematic advantages. It allows the locking plate 43 to adjust its position by sliding when inserted into the locking slot 44 to adapt to different installation angles, thereby enhancing the flexibility of the structure. The arc-shaped locking plate 43 can also automatically adjust the contact surface according to the direction of the external force. This adaptability enables the locking plate 43 to maintain a stable connection under various complex working conditions.
[0044] The contact surface between the arc-shaped locking plate 43 and the locking groove 44 has been optimized to increase the contact area, thereby improving friction and stability. The curved shape of the arc-shaped locking plate 43 serves as a guide, facilitating alignment with the locking groove 44 during installation, thereby improving installation efficiency. Furthermore, the arc-shaped design allows for a certain degree of installation tolerance. Even if there is a slight deviation between the locking plate 43 and the locking groove 44, the adjustment of the arc surface can achieve a stable connection, enhancing the structure's fault tolerance.
[0045] The arc-shaped locking plate 43 achieves a self-locking function through the geometric shape of the locking plate 43, without the need for external energy or complex mechanisms; when the arc-shaped locking plate 43 is inserted into the locking groove, the curved shape of the locking plate 43 forms a tight fit with the inner wall of the locking groove 44, and friction is used to prevent the locking plate 43 from loosening under vibration or impact; this self-locking mechanism ensures that the locking plate 43 remains stable in the locking groove 44 and will not move easily even if it is disturbed by external interference, thereby enhancing the stability and safety of the structure.
[0046] In summary, the arc-shaped design of the locking plate 43 has significant advantages at the principle level. It improves the stability, flexibility and self-locking function of the structure, enabling the deep-water, detachable and environmentally friendly cutter suction dredger with a large dredging depth to operate more stably and efficiently in complex water environments.
