Description

Technical Field

[0001] This invention relates to the field of underwater leveling machine technology, and particularly to a measuring tower for an underwater leveling machine and a multi-degree-of-freedom adjustable underwater leveling machine. Background Technology

[0002] An underwater screed is a type of machinery specifically designed for underwater earthwork leveling operations. It is widely used in marine engineering, water conservancy projects, and other fields. Through its unique design and structure, the underwater screed can effectively level soil underwater to achieve the desired smoothness.

[0003] In order to make the underwater leveling machine visible from the water, a measuring tower is currently installed on the underwater leveling machine, with the top of the measuring tower protruding above the water surface. However, during transportation, the installation of the measuring tower raises the center of gravity of the underwater leveling machine and causes a greater degree of eccentricity, posing a significant safety hazard to the transportation of the underwater leveling machine. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the fact that the setting of the measuring tower raises the center of gravity of the underwater leveling machine during transportation, and causes the underwater leveling machine to have a greater eccentricity, which poses a great hidden danger to the transportation safety of the underwater leveling machine. The invention provides a measuring tower for an underwater leveling machine and a multi-degree-of-freedom adjustable underwater leveling machine.

[0005] In a first aspect, the present invention provides a measuring tower for an underwater leveling machine, comprising:

[0006] Support components;

[0007] It also includes a measuring tower and a drive mechanism connected to the support assembly, the drive mechanism being able to rotate the measuring tower from horizontal to vertical.

[0008] The measuring tower for an underwater screed machine described in this application is mounted on a support assembly. During transportation, the measuring tower is positioned horizontally, effectively reducing its impact on the center of gravity and eccentricity of the underwater screed machine during transport. Then, before launching, the measuring tower is rotated from horizontal to vertical to suit the construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater screed machine is effectively improved while adapting to different construction conditions.

[0009] Preferably, the support assembly includes two spaced-apart end structures connected by a second longitudinal beam, one of the end structures being fitted with a bracket hinged to the measuring tower, and one end of the drive mechanism being connected to the second longitudinal beam and the other end being connected to the measuring tower.

[0010] Preferably, the driving mechanism includes a first telescopic member, which is subjected to tension during the process of the measuring tower rotating from a horizontal to a vertical position and from a vertical to a horizontal position.

[0011] This allows the measurement tower to rotate using a first telescopic component with a smaller diameter, thus reducing the weight of the underwater leveling machine.

[0012] Preferably, the driving mechanism includes a first telescopic member, the support includes support units arranged radially at intervals along the second longitudinal beam, each support unit is installed on the top of the end structure, there is a gap between two support units, and a rotating shaft that rotatably engages with the measuring tower is connected between the two support units, one end of the first telescopic member is hinged to the measuring tower, and the other end of the first telescopic member passes through the gap and is hinged to the second longitudinal beam.

[0013] Preferably, the second longitudinal beam is a truss structure, and the second longitudinal beam includes an upper chord, a lower chord, a vertical member, a first diagonal web member and a second diagonal web member. A transverse beam is provided at the first node of the upper chord, and the vertical member, the first diagonal web member and the second diagonal web member converge at the first node. The transverse beam is connected to the first telescopic member.

[0014] By setting the connection point between the first telescopic member and the second longitudinal beam at the first node, and by gathering the vertical rod, the first diagonal brace and the second diagonal brace at the first node, the second longitudinal beam, as a truss structure, can still meet the tensile stress requirements of the first telescopic member. Compared with using the second longitudinal beam as a box beam, the weight of the second longitudinal beam is greatly reduced, thereby greatly reducing the weight of the underwater leveling machine.

[0015] Preferably, the support unit is a truss structure; the measuring tower is composed of multiple truss sections spliced ​​together sequentially.

[0016] Preferably, the other end structure has a support frame protruding upward at its top, which can support the measuring tower when the measuring tower is arranged horizontally.

[0017] The second aspect discloses a multi-degree-of-freedom adjustable underwater leveling machine, including two measuring towers as described in this application, with a second crossbeam connecting the end structures of adjacent support components.

[0018] It also includes a feeding mechanism, which is capable of moving along the length of the second longitudinal beam and also along the length of the second transverse beam.

[0019] Preferably, it further includes a horizontal sliding frame and a first main frame, wherein:

[0020] The first main frame includes two sets of first horizontal beams and first vertical beams arranged opposite to each other, and the two sets of first horizontal beams and first vertical beams arranged opposite to each other form a frame structure;

[0021] The end structure has a first hole extending through it along the length of the first longitudinal beam.

[0022] The transverse frame is at least partially located within the first hole, and the transverse frame slides in conjunction with the end structure along the length of the first beam.

[0023] The first longitudinal beam passes through the transverse frame and the corresponding second longitudinal beam along the length of the first hole, and slides with the transverse frame and the second longitudinal beam;

[0024] The first vertical lifting outrigger is connected to the second crossbeam;

[0025] The second vertical lifting outrigger is connected to the first longitudinal beam.

[0026] The multi-degree-of-freedom adjustable underwater leveling machine described in this application, when in use, by setting a transverse frame between the end structure and the first longitudinal beam, and based on the sliding cooperation between the first longitudinal beam and the transverse frame along the length of the first hole, achieves the relative movement between the first longitudinal beam and the end structure along the length of the first hole, thereby achieving the purpose of the first vertical lifting leg and the second vertical lifting leg walking in a stepping manner along the length of the first hole.

[0027] Furthermore, based on the sliding engagement with the end structure along the radial direction of the first hole, the relative movement of the first longitudinal beam and the end structure along the radial direction of the first hole is realized, thereby achieving the purpose of the first vertical lifting leg and the second vertical lifting leg moving or correcting their deviation along the length direction of the first hole.

[0028] The present application describes a transverse and longitudinal walking mechanism that utilizes a first longitudinal beam fitted with a transverse frame, and the transverse frame fitted with an end structure. The transverse frame replaces the transition frame of the existing walking leveling machine, thereby effectively reducing the overall weight of the transverse and longitudinal walking mechanism.

[0029] Preferably, a compressed air drainage chamber is provided inside the second crossbeam.

[0030] The second crossbeam is integrated with the compressed air drainage chamber to reduce the overall weight of the lateral and longitudinal walking mechanism.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] The measuring tower for an underwater screed machine described in this application is mounted on a support assembly. During transportation, the measuring tower is positioned horizontally, effectively reducing its impact on the center of gravity and eccentricity of the underwater screed machine during transport. Then, before launching, the measuring tower is rotated from horizontal to vertical to suit the construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater screed machine is effectively improved while adapting to different construction conditions.

[0061] The measuring tower for an underwater screed machine described in this application is mounted on a support assembly. During transportation or launching, the measuring tower 6 is positioned horizontally, effectively reducing its impact on the center of gravity and eccentricity of the underwater screed machine during transport. Then, during launching, the measuring tower is rotated from horizontal to vertical to suit the construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater screed machine is effectively improved while adapting to different construction conditions.

[0062] In a preferred embodiment, the support assembly includes two spaced-apart end structures 13, with a second longitudinal beam 12 connecting the two end structures 13 on the same side of the two support assemblies. One of the end structures 13 is fitted with a bracket 62 hinged to the measuring tower 6. One end of the drive mechanism 61 is connected to the second longitudinal beam 12, and the other end is connected to the measuring tower 6.

[0063] In a preferred embodiment, the drive mechanism 61 includes a first telescopic member, which is subjected to tension during the rotation of the measuring tower 6 from horizontal to vertical and from vertical to horizontal. The first telescopic member is preferably a telescopic hydraulic cylinder or a pneumatic cylinder.

Compared with using the second longitudinal beam 12 as a box beam, the weight of the second longitudinal beam 12 is greatly reduced, thereby greatly reducing the weight of the underwater leveling machine.

[0091] Furthermore, based on the sliding engagement with the end structure 13 along the radial direction of the first hole 131, the relative movement of the first longitudinal beam 22 and the end structure 13 along the radial direction of the first hole 131 is realized, thereby achieving the purpose of the first vertical lifting leg 31 and the second vertical lifting leg 32 moving in a step-like manner or correcting deviation along the length direction of the first hole 131.

[0092] By using the first longitudinal beam 22 to house the transverse frame 33, and the transverse frame 33 to house the end structure 13, the transverse frame 33 is used to replace the transition frame of the existing walking leveling machine, thereby effectively reducing the overall weight of the transverse and longitudinal walking mechanism.

[0123] It also includes a connected measuring tower 6 and a drive mechanism 61, the drive mechanism 61 being able to drive the measuring tower 6 to rotate.

[0124] The drive mechanism 61 can drive the measuring tower 6 to rotate around the length direction of the second crossbeam 11;

[0125] It also includes spaced-apart brackets 62 with a gap between each bracket 62. A rotating shaft 63 connects the brackets 62, and the measuring tower 6 is rotatably engaged with the rotating shaft 63. One end of the driving mechanism 61 is connected to the measuring tower 6, and the other end of the driving mechanism 61 passes through the gap and is connected to the second longitudinal beam 12.

[0126] The drive mechanism 61 can drive the measuring tower 6 to rotate around the length of the second longitudinal beam 12.

[0127] In a preferred embodiment, the transverse frame 33 is provided with a second hole 331 adapted to the first longitudinal beam 22 along the opening direction of the first hole 131. The first longitudinal beam 22 passes through the second hole 331 and slides with the second hole 331. This allows for relative movement between the first longitudinal beam 22 and the transverse frame 33 along the opening direction of the first hole 131. Simultaneously, the adaptation of the first longitudinal beam 22 to the second hole 331 ensures that the second hole 331 provides a limiting effect on the first longitudinal beam 22 radially along the first hole 131.

[0128] In a preferred embodiment, one side of the first hole 131 has a first sidewall 132, and a first gap 114 exists between the transverse frame 33 and the first sidewall 132. The transverse frame 33 moves relative to the end structure 13 to move away from or towards the first sidewall 132. This achieves the purpose of the transverse frame 33 slidingly engaging with the end structure 13 radially along the first hole 131. Simultaneously, the opposing sidewalls on both sides of the first hole 131 (one of which is the first sidewall 132) also limit the movement of the transverse frame 33.

[0129] In a preferred embodiment, a limiting structure is provided between the transverse frame 33 and the end structure 13. This limiting structure restricts the transverse frame 33 from sliding relative to the end structure 13 along the length direction of the first hole 131, but does not restrict the transverse frame 33 from sliding relative to the end structure 13 radially along the first hole 131. However, when the first longitudinal beam 22 moves relative to the transverse frame 33 along the length direction of the first hole 131, no relative movement occurs between the transverse frame 33 and the end structure 13, or the relative displacement is very small [due to assembly and manufacturing errors].

[0130] In a preferred embodiment, the first hole 131 is a rectangular cavity, and the end structure 13 further includes a bottom sidewall 133, a second sidewall 134, and a top sidewall 135. The first sidewall 132, the bottom sidewall 133, the second sidewall 134, and the top sidewall 135 form the first hole 131, which facilitates manufacturing and installation.

[0131] In a preferred embodiment, the net height of the first hole 131 is adapted to the height of the transverse frame 33 to increase the stability of the transverse frame 33 when it moves relative to the end structure 13.

[0132] In a preferred embodiment, the lateral and longitudinal walking mechanism described in this application further includes a lateral telescopic mechanism 4, which is connected between the end structure 13 and the transverse frame 33. The lateral telescopic mechanism 4 can drive the transverse frame 33 away from or closer to the first sidewall 132.

[0133] The lateral telescopic mechanism 4 can drive the lateral frame 33 to reciprocate relative to the end structure 13.

[0134] More preferably, the lateral telescopic mechanism 4 can drive the lateral frame 33 away from or closer to the first sidewall 132.

[0135] In a preferred embodiment, the first transverse support gantry 42 is detachably connected to the outer wall of the end structure 13 to facilitate installation and transportation.

[0136] In a preferred embodiment, a first transverse through-hole 136 is formed on the first sidewall 132, and a first transverse support gantry 42 is provided outside the first transverse through-hole 136. One end of the transverse telescopic mechanism 4 is connected to the root of the first transverse support gantry 42, and the other end passes through the first through-hole 211 and is connected to the transverse frame 33. By using the first transverse support gantry 42 outside the first transverse through-hole 136 as a telescopic support force-bearing component between the transverse frame 33 and the end structure 13, compared with directly setting the transverse telescopic mechanism 4 between the transverse frame 33 and the end structure 13, the size of the end structure 13 along the telescopic direction of the transverse telescopic mechanism 4 is effectively reduced, thereby effectively reducing the overall weight of the transverse and longitudinal walking mechanism.

[0137] In a preferred embodiment, a first transverse support 41 is connected to the transverse frame 33, the first transverse support 41 is located within the first gap 114, and the transverse telescopic mechanism 4 is connected to the first transverse support 41.

[0138] More preferably, the first transverse support gantry 42 is connected to the outer wall of the end structure 13.

[0139] More preferably, the first lateral support gantry 42 is detachably connected to the outer wall of the end structure 13 to facilitate the installation and adjustment of the lateral telescopic mechanism 4.

[0140] In a preferred embodiment, the first transverse support gantry 42 is connected to the outer wall of the end structure 13 by bolts or pins.

[0141] In a preferred embodiment, a first transverse support 41 is connected to the transverse frame 33, the first transverse support 41 is located within the first gap 114, and the transverse telescopic mechanism 4 is connected to the first transverse support 41.

[0142] The longitudinal and lateral walking mechanism described in this application further includes a longitudinal telescopic mechanism 5, which is connected between the first longitudinal beam 22 and the transverse frame 33. The longitudinal telescopic mechanism 5 is capable of telescopically extending and retracting along the length of the first longitudinal beam 22. The longitudinal telescopic mechanism 5 drives the first longitudinal beam 22 to slide and engage with the transverse frame 33 along the length of the first hole 131.

[0143] In a preferred embodiment, a first longitudinal support 51 is connected to the transverse frame 33, a second longitudinal support 52 is connected to the first longitudinal beam 22, the first longitudinal support 51 is located within the first gap 114, and the longitudinal telescopic mechanism 5 is connected between the first longitudinal support 51 and the second longitudinal support 52.

[0144] In a preferred embodiment, the entire transverse frame 33 is located within the first hole 131.

[0145] In a preferred embodiment, the first longitudinal beam 22 is provided with a first vertical through hole 221, and a first vertical support gantry 223 is provided on the upper part of the first vertical through hole 221. One end of the second vertical lifting leg 32 is connected to the first vertical support gantry 223, and the other end passes through the first vertical through hole 221 and slides vertically with the first vertical through hole 221. By using the first vertical support gantry 223 on the upper part of the first vertical through hole 221 as a telescopic support force-bearing component between the second vertical lifting leg 32 and the first longitudinal beam 22, compared with a direct connection between the second vertical lifting leg 32 and the first longitudinal beam 22, the center of gravity of the first longitudinal beam 22 can be effectively lowered with less increase in structural weight, thereby effectively lowering the center of gravity of the whole formed by the end structure 13, the transverse frame 33 and the first longitudinal beam 22, resulting in better stability of the transverse and longitudinal walking mechanism.

[0146] The second vertical lifting leg 32 and the first vertical lifting leg 31 preferably have the same structure.

[0147] The following is a preferred embodiment of the bidirectional walking underwater leveling machine of this embodiment, including: four horizontal and vertical walking mechanisms as described in Embodiment 1; the four horizontal and vertical walking mechanisms are arranged in an array, adjacent end structures 13 are connected, and adjacent first longitudinal beams 22 are connected.

[0148] In a preferred embodiment, a second longitudinal beam 12 is connected between adjacent end structures 13 along the opening direction of the first hole 131. The second longitudinal beam 12 has a first through hole 121 corresponding to the first hole 131, and one end of the first longitudinal beam 22 extends into the first through hole 121. Based on the sliding engagement of the transverse frame 33 with the end structure 13 radially along the first hole 131, the first longitudinal beam 22 is inserted into the second longitudinal beam 12, forming an inner-outer nested relationship between the first longitudinal beam 22 and the second longitudinal beam 12. This effectively reduces the overall horizontal arrangement space formed by the first longitudinal beam 22 and the second longitudinal beam 12, allowing for a smaller lateral dimension of the bidirectional underwater leveling machine.

[0149] In a preferred embodiment, the second longitudinal beam 12 is a truss structure with open ends. While ensuring the second longitudinal beam 12 meets design stiffness and strength requirements, its self-weight is further reduced, contributing to the lightweight design of the bidirectional underwater leveling machine of this application. Simultaneously, since the second longitudinal beam 12 is fitted outside the first longitudinal beam 22, its lateral and height dimensions are larger than the first longitudinal beam 22, thus enabling the second longitudinal beam 12 to be constructed as a truss structure.

[0150] In a preferred embodiment, along the direction of movement of the transverse frame 33 relative to the end structure 13, a first crossbeam 21 is connected to the end of the adjacent first longitudinal beam 22. Preferably, the first crossbeam 21 and the first longitudinal beam 22 form a frame structure.

[0151] In a preferred embodiment, a support telescopic structure is provided between the second longitudinal beam 12 and the first longitudinal beam 22. The support telescopic structure is located in the middle of the second longitudinal beam 12. When the first longitudinal beam 22 and the second longitudinal beam 12 move relative to each other, the support telescopic structure disengages from either the second longitudinal beam 12 or the first longitudinal beam 22, thereby not interfering with the relative movement between the first longitudinal beam 22 and the second longitudinal beam 12. When the second longitudinal beam 12 and the first longitudinal beam 22 are relatively stationary, the support telescopic structure extends and retracts, supporting the first longitudinal beam 22 and the second longitudinal beam 12, so that the second longitudinal beam 12 and the first longitudinal beam 22 bear each other's force in the lateral and vertical directions, forming an integral unit. It cooperates with the lateral telescopic mechanism 4 and the longitudinal telescopic mechanism 5 to jointly increase the stability of the bidirectional walking underwater leveling machine.

[0152] In a preferred embodiment, the height of the first crossbeam 21 is adapted to the height of the first longitudinal beam 22; the height of the second crossbeam 11 is higher than the height of the first crossbeam 21; and the height of the second longitudinal beam 12 is adapted to the height of the second crossbeam 11. Based on the sequential arrangement of the first longitudinal beam 22, the transverse frame 33, and the end structure 13, with the end structure 13 being higher than the first longitudinal beam 22, adapting the height of the first crossbeam 21 to the height of the second crossbeam 11 results in a more uniform lateral and longitudinal stress, stiffness, and load-bearing capacity in the frame structure formed by the first crossbeam 21 and the first longitudinal beam 22. This allows for better lateral and longitudinal stability while reducing the weight of the bidirectional underwater leveling machine. Similarly, adapting the height of the second longitudinal beam 12 to the height of the second crossbeam 11 also results in a more uniform lateral and longitudinal stress, stiffness, and load-bearing capacity in the frame structure formed by the second longitudinal beam 12 and the second crossbeam 11. This allows for better lateral and longitudinal stability while reducing the weight of the bidirectional underwater leveling machine.

[0153] In a preferred embodiment, the second crossbeam 11 is provided with a compressed air drainage chamber 112 for leveling the bidirectional underwater screed and controlling the buoyancy and descent of the bidirectional underwater screed.

[0154] In a preferred embodiment, a support beam 14 is provided on the side of the second crossbeam 11 near the first crossbeam 21, and the first vertical lifting leg 31 is connected to the support beam 14.

[0155] In a preferred embodiment, the support beam 14 is provided with a second vertical through hole 141.

[0156] The bidirectional walking underwater leveling machine described in this embodiment further includes a second vertical support gantry 142 disposed on the upper part of the second vertical through hole 141. The cantilever end of the second vertical support gantry 142 is detachably connected to the support beam 14. One end of the first vertical lifting leg 31 is connected to the root of the second vertical support gantry 142, and the other end passes through the second vertical through hole 141 and slides vertically with the second vertical through hole 141.

[0157] In a preferred embodiment, the first longitudinal beams 22 on adjacent transverse and longitudinal walking mechanisms are connected in a corresponding manner along the length direction of the first longitudinal beam 22.

[0158] In a preferred embodiment, the first longitudinal beams 22 on adjacent transverse and longitudinal walking mechanisms are coaxially integrally formed along the length direction of the first longitudinal beam 22.

[0167] The bidirectional underwater screed described in this application, during construction, involves pressing the upper discharge pipe 72 vertically downwards through the material box 71, thereby opening the material gate 713 and connecting the hopper 711 with the upper discharge pipe 72. At this time, the stones in the hopper 711 fall into the upper discharge pipe 72 and then into the lower discharge pipe 73. Meanwhile, some air or water in the upper discharge pipe 72 and the lower discharge pipe 73 is discharged through the first channel 74 between the upper discharge pipe 72 and the lower discharge pipe 73, achieving the purpose of smooth material flow from the material box 71 to the lower discharge pipe 73, thus achieving the purpose of smooth material discharge during the operation of the screed.

[0170] The upper feeding pipe 72 includes an upper pipe structure 721. A plurality of protrusions 722 are arranged circumferentially on the outer wall of the upper pipe structure 721. There is a first gap 723 between adjacent protrusions 722. The outer surface of the protrusions 722 is an inclined surface 724 corresponding to the first funnel structure 732. The lower part of the upper pipe structure 721 is inserted into the bottom pipe structure 731, and there is a second gap 725 between the outer wall of the upper pipe structure 721 and the inner wall of the bottom pipe structure 731, which is connected to the first gap 723.

[0171] The bottom tube structure 731 and the first funnel structure 732 are welded together, and a first connecting rib plate 733 is welded between the outer wall of the bottom tube structure 731 and the outer wall of the first funnel structure 732. A plurality of lower lifting lugs 734 are connected to the top outer wall of the first funnel structure 732, and all the lower lifting lugs 734 are arranged around the first funnel structure 732.

[0172] All of the lower lugs 734 are located near the large opening end of the first funnel structure 732.

[0173] In a preferred embodiment, the upper feeding pipe 72 further includes a second funnel structure 726 sleeved on the outside of the upper pipe structure 721. The second funnel structure 726 faces the first funnel structure 732 and can cover the large opening end of the first funnel structure 732. A third gap 741 is connected between the first funnel structure 732 and the second funnel structure 726 through the first gap 723. The third gap 741, the first gap 723 and the second gap 725 form the first channel 74.

[0174] The upper tube structure 721 has a first block 720 located on the outer side of the lower part of the first funnel structure 732. At least one side of the first block 720 can laterally abut against the inner wall of the bottom tube structure 731. This is to increase the connection stability between the upper tube structure 721 and the lower feed tube 73.

[0175] In a preferred embodiment, the upper tube structure 721 further includes at least two upper tube sections 727 that are detachably connected in sequence along the length of the upper tube structure 721, and the second funnel structure 726 is located on the lowermost upper tube section 727.

[0176] In a preferred embodiment, the upper tube structure 721 further includes a third funnel structure 728 connected to the top of the upper tube structure 721, with the larger end of the third funnel structure 728 facing upwards.

[0177] In a preferred embodiment, the material bin 71 further includes a hopper 711, the bottom of which has an opening 712, and a material gate 713 is provided at the opening 712. The material gate 713 can be closed or opened, and the material gate 713 and the third funnel structure 728 are configured such that when the material gate 713 presses the third funnel structure 728 vertically downward, the material gate 713 can be opened.

[0178] Specifically, when the material gate 713 presses vertically downwards against the large opening of the third funnel structure 728, the material gate 713 can be opened.

[0179] In a preferred embodiment, the top of the third funnel structure 728 is provided with a limiting ring 729 protruding upward; the limiting ring 729 can vertically abut against the material gate 713.

[0180] Preferably, the material gate 713 includes two opposing half-gate structures 714, which are hinged to the hopper 711 via a first hinge shaft 716. When the material gate 713 presses down vertically on the large end of the third funnel structure 728, the two half-gate structures 714 rotate in opposite directions to form an opening 715 connecting the hopper 711 and the first funnel structure 732.

[0185] The hopper 711 is equipped with a spiral structure, which is vertically oriented and leads to the opening 712. The spiral structure is detachably connected to the hopper 711. This structure is used to reduce the impact force of materials on the half-door structure 714 and prevent the half-door structure 714 from deforming too much and becoming unable to open.

[0186] In a preferred embodiment, the feeding mechanism 7 is movable along the length of the first longitudinal beam 22 and also along the length of the first transverse beam 21, specifically as follows:

[0187] The feeding mechanism 7 is connected to a longitudinal moving mechanism 9, which can drive the feeding mechanism 7 to move along the length of the first longitudinal beam 22. More specifically and preferably, the lower feeding pipe 73 is connected to the longitudinal moving mechanism 9.

[0188] In a preferred embodiment, the longitudinal moving mechanism 9 includes a longitudinal support 91, a material tube support 92, and a longitudinal driving mechanism 93, wherein: the material tube support 92 is connected to the feeding mechanism 7; the longitudinal support 91 includes two parallel longitudinal support rails 911 spaced apart, the material tube support 92 is located between the two longitudinal support rails 911, and the material tube support 92 and the two longitudinal support rails 911 are in rolling engagement via longitudinal rollers 920; the feeding mechanism 7 is supported on the material tube support 92, and the longitudinal driving mechanism 93 is mounted on the material tube support 92. Preferably, the longitudinal driving mechanism 93 includes a first drive motor 931 and a meshing first gear 932 and a first rack 933, the first drive motor 931 driving the first gear 932 to rotate. This allows the material tube support 92 to move relative to the longitudinal support rails 911 along the length direction of the longitudinal support rails 911. Specifically, preferably, the material tube support 92 is connected to the lower feeding tube 73.

[0189] Preferably, the material tube support 92 is sleeved and connected to the outside of the feeding mechanism 7.

[0190] In a preferred embodiment, the lower feed pipe 73 moves laterally relative to the second crossbeam 11 via a lateral moving mechanism.

[0191] In a preferred embodiment, the lateral movement mechanism includes a second drive motor 84, a meshing second gear 82 and a second rack 83, and two parallel transverse rails 81 mounted on the second crossbeam 11. Both the second rack 83 and the transverse rails 81 are mounted on the second crossbeam 11 and are arranged along the length of the second crossbeam 11. The second drive motor 84 drives the second gear 82 to mesh and rotate with the second rack 83. The second gear 82 is connected to the end of the longitudinal support 91 along the length of the longitudinal support rail 911. A transverse roller 86 is provided at the end of the longitudinal support 91, and the transverse roller 86 rolls in engagement with the transverse rails 81.

[0192] When the longitudinal support 91 is provided, the lateral movement mechanism drives the longitudinal support 91 and the second crossbeam 11 to move laterally, thereby achieving the purpose of the lower feed pipe 73 moving laterally relative to the second crossbeam 11.

[0193] The lateral movement mechanism includes a meshing second gear 82 and a second rack 83, and two parallel transverse rails 81 mounted on the second crossbeam 11. It also includes a second drive motor 84, which drives the second gear 82 and the second rack 83 to mesh and rotate.

[0194] Preferably, the second drive motor 84 has output shafts 85 connected to both ends, and the output shafts 85 are connected to the second gear 82 at the end near the second crossbeam 11. The second crossbeam 11 has a second rack 83 along its length, and the second gear 82 meshes with the second rack 83 on the corresponding side.

[0195] Preferably, at least two ballast drainage chambers 112 are provided inside the second crossbeam 11, and a partition 1121 is provided between adjacent ballast drainage chambers 112. A water passage hole 1122 is provided on the partition 1121, and an inlet / outlet 1123 is provided at the bottom of each ballast drainage chamber 112. Preferably, a sealing door is provided at each inlet / outlet 1123, which can be controlled to open or close the inlet / outlet 1123, for example, using a waterproof electronic switch. Alternatively, a sealing door may not be provided at the inlet / outlet 1123.

[0196] Ballast drainage tank 112 is used to level the multi-degree-of-freedom adjustable underwater leveler underwater and control the floating and sinking of the multi-degree-of-freedom adjustable underwater leveler.

[0197] Two spaced second crossbeams 11 are provided, and ballast drainage chambers 112 are provided inside the second crossbeams 11. Since the second crossbeams 11 are provided with ballast drainage chambers 112, the second crossbeams 11 and ballast drainage chambers 112 are integrated into one unit, thereby reducing the weight of the underwater leveling machine.

[0198] The following is a weight comparison between the leveling machine of this application and the walking leveling machine in the prior art: When the effective leveling size reaches 18m×10m, the leveling speed reaches 2m / min, and the working water depth reaches 19m, the total weight of the multi-degree-of-freedom adjustable underwater leveling machine described in this application is 75t-85t, which is much less than the 185t total weight of the existing walking leveling machine.

[0199] Buoyancy Explanation: Six compressed air drainage chambers 112 are arranged on each of the two second crossbeams 11, for a total of 12 compressed air drainage chambers 112 in the whole machine; the maximum buoyancy generated by the two second crossbeams 11 is about 50t; both the first longitudinal beam 22 and the first crossbeam 21 are equipped with sealed chambers, so that the first longitudinal beam 22 and the first crossbeam 21 can be used as pontoons, each generating about 20t of buoyancy. The total buoyancy generated by the second crossbeams 11, the first longitudinal beam 22 and the first crossbeam 21 is greater than the total weight of the multi-degree-of-freedom adjustable underwater leveler, while the total buoyancy generated by the first longitudinal beam 22 and the first crossbeam 21 is less than the total weight of the multi-degree-of-freedom adjustable underwater leveler.

[0200] In the above situation, the explanation for the whole machine sinking to the bottom and buoyancy assisting to rise from the water is as follows:

[0201] 1. Before lifting and launching the machine, the overall status is as follows: the measuring tower 6 is laid down, the first longitudinal beam 22, the unloading mechanism 7, the lateral movement mechanism, and the longitudinal movement mechanism 9 are all in the center position, the main hook of the crane is attached to the four lifting points on the two second crossbeams 11, and the auxiliary hook of the crane is attached to the unloading mechanism 7. The whole machine is lifted to the designated position and placed on the water surface. The slings are loosened. At this time, the buoyancy of the whole machine is greater than its own weight, and it is in a floating state. At the same time, the exhaust valve of one compressed air drainage chamber 112 of each second crossbeam 11 is opened symmetrically to observe the water level of the whole machine. When the leveling machine sinks, the exhaust valve is closed. The crane is operated to slowly release the hook until the leveling machine sinks to the bottom. After all the exhaust valves are opened to allow water to enter the compressed air drainage chamber 112, the operator controls the erection of the measuring tower 6 through the control box to carry out the subsequent measurement, positioning and leveling operations.

[0202] 2. When the whole machine needs to be drained, the measuring tower 6 is lowered. First, the upper discharge pipe 72 and the lower discharge pipe 73 of the discharge mechanism 7 are lifted off separately. Then, the hook is attached to the lifting slings of the four lifting points of the leveling machine. At the same time, the air inlet valve of one compressed air drainage chamber 112 of each second crossbeam 11 is opened symmetrically to compress air. After the water in one chamber is drained, the current valve is closed. Then, the air inlet valve of the next compressed air drainage chamber 112 of each crossbeam is opened symmetrically. The operation is repeated. During the drainage process, the crane's lifting weight display screen is observed. When the displayed lifting weight drops to the target value range, the exhaust valve is closed. The hook is raised until the whole machine floats out of the water.

[0203] The top of the measuring tower 6 is equipped with a GPS or Beidou positioning system.

[0204] The measuring tower 6 described in this embodiment is installed on the end structure 13. During transportation, the measuring tower 6 is positioned horizontally, effectively reducing its impact on the center of gravity and eccentricity of the underwater screed during transport. Then, during launching, the measuring tower is rotated from horizontal to vertical to suit the construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater screed is effectively improved while adapting to the construction conditions. Simultaneously, during transportation or launching, the slight oscillation of the measuring tower 6 can be used to fine-tune the center of gravity of the underwater screed using multiple degrees of freedom, making construction safer.

[0205] This embodiment also provides a construction method for a multi-degree-of-freedom adjustable underwater leveling machine, including the following steps: S1: The first vertical lifting leg 31 supports the multi-degree-of-freedom adjustable underwater leveling machine, and the second vertical lifting leg 32 is separated from the bottom of the water; S2: The first longitudinal beam 22 is driven to move relative to the end structure 13 along the length direction of the first longitudinal beam 22; S3: The second vertical lifting leg 32 falls and supports the multi-degree-of-freedom adjustable underwater leveling machine; S4: The first vertical lifting leg 31 rises and separates from the bottom of the water; S5: The end structure 13 is driven to move relative to the first longitudinal beam 22 along the length direction of the first longitudinal beam 22.

[0206] A preferred embodiment 1 further includes the following steps: installing the multi-degree-of-freedom adjustable underwater leveler; setting up a crane on a platform on the seaward side of the multi-degree-of-freedom adjustable underwater leveler; lifting the multi-degree-of-freedom adjustable underwater leveler with the crane and rotating it to the seaward side of the crane; and lowering the multi-degree-of-freedom adjustable underwater leveler into the water.

[0207] A preferred embodiment 2 further includes a launching step for the multi-degree-of-freedom adjustable underwater screed: based on a first platform and a slope located on one side of the lower feed pipe 73 of the first platform, the slope extending to the bottom of the water; the multi-degree-of-freedom adjustable underwater screed is installed on the lower feed pipe 73 of the first platform, and the multi-degree-of-freedom adjustable underwater screed descends the slope using the methods described in steps S1-S5 until it reaches the construction position. Steps are provided on the slope, and the first vertical lifting leg 31 and the second vertical lifting leg 32 can be supported on the steps. This ensures that when the multi-degree-of-freedom adjustable underwater screed is launched or launched from the slope, the first vertical lifting leg 31 and the second vertical lifting leg 32 remain vertically positioned, preventing them from tilting and supporting the multi-degree-of-freedom adjustable underwater screed. This effectively optimizes the stress on the first vertical lifting leg 31 and the second vertical lifting leg 32, extending their service life.

[0208] In a preferred manner, before construction, the installation steps of the multi-degree-of-freedom adjustable underwater screed are also included: B1. Prepare the site for assembly; transfer the components of the walking underwater screed to the installation site, and at the same time, take into account the working conditions of the installation site to avoid the hydraulic system and electrical control system being soaked in seawater due to the rise and fall of the tide. B2. Assemble the second crossbeam 11, and install end structures 13 and transverse frames 33, as well as first vertical lifting legs 31 and transverse telescopic mechanisms 4 at both ends of the second crossbeam 11; B3. Install the fabric longitudinal beam 12, connecting both ends of the fabric longitudinal beam 12 to the end structures 13; B4. Install the first longitudinal beam 22, which passes through the fabric longitudinal beam 12 and the end structures 13 on the same side, and install the second vertical lifting legs 32 on the first longitudinal beam 22; B5. Install the first crossbeam 21 between adjacent first longitudinal beams 22, with the first crossbeam 21 located outside the second crossbeam 11; B6. Install the feeding mechanism 7, the longitudinal moving mechanism 9, and the transverse moving mechanism between the two second crossbeams 11, wherein the longitudinal moving mechanism 9 can drive the feeding mechanism 7 to move along the length direction of the first longitudinal beam 22; and the transverse moving mechanism can drive the longitudinal moving mechanism 9 to move laterally relative to the second crossbeam 11 along the length direction of the second crossbeam 11; B7. Install the measuring tower 6 on the top of the end structure 13; B8. The hydraulic and electrical systems of the entire machine were installed, and then the entire machine was debugged and a land simulation experiment was conducted.

[0209] The above description is merely 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 within the protection scope of the present invention.
