Description

Technical Field

[0001] This invention relates to the field of underwater screed construction technology, and particularly to an automatic filling system for an underwater screed and an underwater screed. Background Technology

[0002] Currently, during underwater operations, the material distribution pipe of an underwater screed needs to move laterally and longitudinally, making it difficult to feed materials into the pipe. Currently, feeding is generally done through a feeding hopper. For example, patent publication number CN215715327U discloses a feeding hopper for an underwater screed. Specifically, an excavator loads materials into the feeding hopper, then a crane lifts the hopper above the material distribution pipe. The bottom of the hopper is then opened, allowing the materials to fall into the material distribution pipe. The crane then lifts the hopper back to the vicinity of the excavator, which loads materials into the hopper, and this process is repeated.

[0003] The above process requires the cooperation of excavators, cranes, and underwater levelers, which is difficult. More importantly, the material can only be fed into the placing pipe intermittently, which severely limits the speed of conveying the stone. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, which requires the cooperation of excavators, cranes and underwater levelers for feeding through a feeding hopper, which is difficult and severely limits the speed of conveying stones. The invention provides an automatic filling system for an underwater leveler and an underwater leveler.

[0005] In a first aspect, the present invention provides an automatic filling system for an underwater leveling machine, comprising:

[0006] A material placement tube is used to be installed on an underwater screed. The material placement tube is open at both the top and bottom and can move laterally and longitudinally along the underwater screed. Base The material conveying mechanism includes at least two connected and relatively movable material conveying sections. The material conveying section located at the root is defined as the root material conveying section. The root material conveying section is connected to the base and has a feed inlet. The material conveying section located at the foremost end is defined as the end material conveying section. The material drop position at the front end of the end material conveying section is vertically aligned with the top of the material distribution pipe.

[0007] The automatic filling system for an underwater screed described in this application includes a material conveying mechanism comprising at least two connected and relatively movable material conveying sections. Throughout the process, the material drop position at the front end of the end material conveying section is always vertically aligned with the top of the material distribution pipe. This allows the material conveying mechanism to continuously transport stones into the material distribution pipe as it moves laterally and longitudinally along the underwater screed, effectively increasing the speed of stone transport while reducing labor costs.

[0008] Preferably, the end conveying section is pitch-rotatably connected to the adjacent conveying section.

[0009] Preferably, the end conveying section is hinged to the adjacent conveying section, and the end conveying section and the adjacent conveying section are rotatably connected by a telescopic bracket. The telescopic bracket includes a hinged connecting frame and a telescopic component. The connecting frame is fixedly connected to one of the end conveying section and the adjacent conveying section, and the telescopic component is hinged to the other.

[0010] Preferably, the end conveying section is arranged to extend relative to the adjacent conveying section.

[0011] Preferably, the end conveying section includes a first conveyor belt, and the conveying section adjacent to the end conveying section includes a second conveyor belt. A second conveying support is provided below the second conveyor belt, and a first space is provided inside the second conveying support. At least a portion of the first conveyor belt can slide into the first space.

[0012] Preferably, the root conveying section is rotatably connected to the base.

[0013] Preferably, it further includes a telescopic mechanism, wherein the base is hinged to the end of the root conveying section away from the end conveying section, and the telescopic mechanism is hinged between the base and the root conveying section.

[0014] Preferably, it also includes a front wheel assembly and a rear wheel assembly, wherein the front wheel assembly is connected to the front side of the bottom of the base; and the rear wheel assembly is connected to the rear side of the bottom of the base.

[0015] Preferably, the front wheel assembly is rotatably arranged relative to the base.

[0016] Preferably, the rear wheel assembly is rotatably arranged relative to the base.

[0017] Preferably, the fabric tube includes an upper material tube and a lower material tube: the upper material tube is connected above the lower material tube, and a first channel is formed between the upper material tube and the lower material tube.

[0018] Preferably, a limiting structure is provided at the front end of the end conveying section, the limiting structure is horizontally limited and cooperates with the material distribution pipe, and a pressure sensor is horizontally arranged between the limiting structure and the material distribution pipe.

[0019] In a second aspect, the present invention provides an underwater leveling machine, including an automatic filling system for an underwater leveling machine as described in this application, and further including a first main frame and a second main frame, wherein: the first main frame includes two spaced-apart first longitudinal beams, and a first crossbeam connects the ends of the two first longitudinal beams on the same side; at least four second vertical lifting legs are supported and connected on the first main frame; the second main frame includes four arrayed end structures, with second longitudinal beams connecting adjacent end structures along the longitudinal direction, and second crossbeams connecting adjacent end structures along the transverse direction; the second longitudinal beams are sleeved on the outer side of the corresponding first longitudinal beams, and the first longitudinal beams are movable relative to the second longitudinal beams along their length; the second crossbeams are located on the first... Inside the crossbeam, at least four first vertical lifting legs are supported and connected to the second main frame; the end structure has a first hole extending through the length of the first longitudinal beam, and a transverse frame is provided in the first hole. The transverse frame is sleeved on the first longitudinal beam and slides with the first longitudinal beam through a longitudinal telescopic mechanism. The transverse frame slides with the end structure along the length of the second crossbeam through a lateral telescopic mechanism. The transverse frame and the end structure are relatively fixed along the direction of the first longitudinal beam; a lateral moving mechanism is provided between adjacent second crossbeams, and a longitudinal moving mechanism is provided on the lateral moving mechanism. The lateral moving mechanism is used to drive the fabric tube to move laterally, and the longitudinal moving mechanism is used to drive the fabric tube to move longitudinally.

[0020] The underwater leveling machine described in this application uses a transverse frame between the end structure and the first longitudinal beam. Based on the sliding engagement between the first longitudinal beam and the transverse frame along the length of the first longitudinal beam, relative movement between the first longitudinal beam and the end structure is achieved, thereby enabling the walking movement of the first and second vertical lifting legs. Furthermore, based on the sliding engagement with the end structure along the radial direction of the first hole, relative movement between the first longitudinal beam and the end structure along the radial direction of the first hole is achieved, thereby enabling the walking movement or correction of the first and second vertical lifting legs along the length of the first hole. Moreover, by using the transverse frame to enclose the first longitudinal beam, and the end structure to enclose the transverse frame, the transverse frame replaces the transition frame of existing walking leveling machines, effectively reducing the overall weight of the transverse and longitudinal walking mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic filling system for an underwater screed described in this application includes a material conveying mechanism comprising at least two connected and relatively movable material conveying sections. Throughout the process, the material drop position at the front end of the end material conveying section is always vertically aligned with the top of the material distribution pipe. This allows the material conveying mechanism to continuously transport stones into the material distribution pipe as it moves laterally and longitudinally along the underwater screed, effectively increasing the speed of stone transport while reducing labor costs.

[0046] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0047] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0048] The use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation.

Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0049] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0050] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0052] Example 1 like Figures 1-8 As shown in the figure, the automatic filling system for an underwater leveling machine described in this embodiment includes a base 71, a material distribution pipe 7, and a material conveying mechanism.

[0053] In a preferred embodiment, the material distribution pipe 7 is used to be installed on an underwater screed, and the material distribution pipe 7 is open at both the top and bottom, and the material distribution pipe 7 can move laterally and longitudinally along the underwater screed.

[0054] like Figure 1 and Figure 2 As shown, the material conveying mechanism includes at least two connected and relatively movable material conveying sections. The material conveying section located at the root is defined as the root material conveying section 751, which is connected to the base 71. The root material conveying section 751 is provided with a feed inlet 753. The material conveying section located at the foremost end is defined as the end material conveying section 752. The material drop position at the front end of the end material conveying section 752 is vertically aligned with the top of the material distribution tube 7. When the material distribution tube 7 moves, the material drop position at the front end of the end material conveying section 752 also moves synchronously, so that the material drop position at the front end of the end material conveying section 752 is always within the material receiving range directly above the material distribution tube 7.

[0055] The automatic filling system for an underwater screed described in this embodiment includes at least two connected and relatively movable conveying sections in the material conveying mechanism. Throughout the process, the material drop position at the front end of the end conveying section 752 is always vertically aligned with the top of the material distribution pipe 7. This allows the material conveying mechanism to continuously convey stones into the material distribution pipe 7 as the material distribution pipe 7 moves laterally and longitudinally along the underwater screed, thereby effectively increasing the speed of stone conveying and reducing labor costs.

[0056] like Figure 5 As shown, in a preferred embodiment, the end conveying section 752 is pitch-rotatably connected to the adjacent conveying section.

[0057] like Figure 5 As shown, in a preferred embodiment, the end conveying section 752 is hinged to the adjacent conveying section, and the end conveying section 752 and the adjacent conveying section can be tilted and rotated relative to each other via a telescopic bracket 76. The telescopic bracket 76 includes a hinged connecting frame 761 and a telescopic member 762. The connecting frame 761 is fixedly connected to one of the end conveying section 752 and the adjacent conveying section, and the telescopic member 762 is hinged to the other.

[0058] In a preferred embodiment, the end conveying section 752 is hinged to the adjacent conveying section via a first hinge shaft 754.

[0059] In a preferred embodiment, the connecting frame 761 is fixedly connected to the conveying section adjacent to the end conveying section 752, one end of the telescopic member 762 is hinged to the connecting frame 761 via a second hinge shaft 763, and the other end of the telescopic member 762 is hinged to the end conveying section 752 via a third hinge shaft 764; the connecting frame 761 is located below the aforementioned conveying section.

[0060] In a preferred embodiment, the end conveying section 752 is a tubular structure, with its end near the adjacent conveying section being higher and its end near the distribution pipe 7 being lower, thereby enabling the stone to move within the end conveying section 752.

[0061] The remaining conveying sections are preferably conveyor belts. Among them, at least one end of the root conveying section 751 is lower than one end of its end conveying section 752, so that the stone can be transported obliquely upward through the root conveying section 751.

[0062] In a preferred embodiment, the first hinge shaft 754, the second hinge shaft 763, and the third hinge shaft 764 are arranged in parallel.

[0063] In a preferred embodiment, the end conveying section 752 is arranged to extend and retract relative to the adjacent conveying section.

[0064] In a preferred embodiment, the end conveying section 752 includes a first conveyor belt 755 and a first conveying bracket 758 supported and connected to the lower part of the first conveyor belt 755. The conveying section adjacent to the end conveying section 752 includes a second conveyor belt 756. A second conveying bracket 757 is supported and connected below the second conveyor belt 756. A first space 759 is provided in the second conveying bracket 757. At least a portion of the first conveyor belt 755 can slide into the first space 759.

[0065] The material dropping position at the front end of the end conveying section 752 can be adjusted by setting telescopic rods between adjacent conveying sections to allow them to extend and retract with each other, or by using a traction trolley and wire rope in conjunction with each other.

[0066] In one preferred embodiment, adjacent conveying sections extend and retract with each other via a telescopic mechanism, such as a hydraulic cylinder or a linear module, while simultaneously using rollers to reduce the frictional force between adjacent conveying sections.

[0067] like Figure 3As shown, another preferred embodiment, taking a two-section conveying section as an example, involves a traction winch 714 positioned near the rear end of the root conveying section 751, and a guide pulley 715 positioned near the front end of the root conveying section 751. A first rope 718 and a second rope 717 are drawn from the traction winch 714. The first rope 718 passes over the guide pulley 715 and connects to the end of the end conveying section 752 near the end of the root conveying section 751. The second rope 717 passes over the over-rope pulley 716 and connects to the end of the end conveying section 752 near the end of the root conveying section 751. A portion of the end conveying section 752 extends into the first space 759. When the traction winch 714… 4. When rotating forward, the first rope 718 is wound up and the second rope 717 is released. The first rope 718 pulls the end material conveying section 752 away from the traction winch 714, causing the material conveying mechanism to extend as a whole. When the traction winch 714 rotates in reverse, the first rope 718 is released and the second rope 717 is wound up. The first rope 718 pulls the end material conveying section 752 towards the traction winch 714, causing the material conveying mechanism to shorten as a whole. This adjusts the material drop position at the front end of the end material conveying section 752, thereby effectively ensuring that the material drop position at the front end of the end material conveying section 752 is always within the material receiving range directly above the material distribution pipe 7.

[0068] In a preferred embodiment, the root conveying section 751 is rotatably connected to the base 71.

[0069] In a further preferred embodiment, the device further includes a telescopic mechanism 711, wherein the base 71 is hinged to the end of the root conveying section 751 away from the end conveying section 752, and the telescopic mechanism 711 is hinged between the base 71 and the root conveying section 751.

[0070] Preferably, it also includes a front wheel assembly 712 and a rear wheel assembly 713, wherein the front wheel assembly 712 is connected to the front side of the bottom of the base 71, and the rear wheel assembly 713 is connected to the rear side of the bottom of the base 71.

[0071] like Figure 6 and Figure 7 As shown, preferably, the front wheel assembly 712 is rotatably arranged relative to the base 71. More preferably, the front wheel assembly 712 rotates relative to the base 71 via a first rotary gear ring 771. The first rotary gear ring 771 includes a rotary bearing, and teeth are provided on the outer wall of the outer ring of the rotary bearing, making the outer ring of the rotary bearing an external gear. The first rotary gear ring 771 can be driven by a motor to mesh with the gear, thereby driving the front wheel assembly 712 to rotate relative to the base 71.

[0072] like Figure 8As shown, preferably, the rear wheel assembly 713 is rotatably arranged relative to the base 71. More preferably, the rear wheel assembly 713 rotates relative to the base 71 via a second rotary gear ring 772. The second rotary gear ring 772 includes a rotary bearing, and teeth are provided on the outer wall of the outer ring of the rotary bearing, making the outer ring of the rotary bearing an external gear. The second rotary gear ring 772 can be driven by a motor to mesh with the gear and the teeth of the second rotary gear ring 772, thereby driving the rear wheel assembly 713 to rotate relative to the base 71.

[0073] By rotating the front wheel assembly 712 and the rear wheel assembly 713 relative to the base 71, the material conveying mechanism can move both laterally and longitudinally, so as to cooperate with the material distribution pipe 7 to convey stone materials when moving laterally and longitudinally along the underwater leveling machine.

[0074] Preferably, a limiting structure is provided at the front end of the end conveying section 752. The limiting structure is horizontally limited and cooperates with the material distribution tube 7. A pressure sensor is horizontally arranged between the limiting structure and the material distribution tube 7. When there is a deviation between the material drop position at the front end of the end conveying section 752 and the material receiving range directly above the material distribution tube 7, the limiting structure and the material distribution tube 7 come into contact through the pressure sensor. The pressure sensor feeds back a pressure signal, and the relative position of the end conveying section 752 and the material distribution tube 7 is adjusted based on the pressure signal to ensure that the material drop position at the front end of the end conveying section 752 is always within the material receiving range directly above the material distribution tube 7.

[0075] In a preferred embodiment, the fabric tube 7 includes an upper material tube 72 and a lower material tube 73: the upper material tube 72 is connected above the lower material tube 73, and a first channel is formed between the upper material tube 72 and the lower material tube 73.

[0076] In a further preferred embodiment, the upper material pipe 72 and the lower material pipe 73 are inserted into each other, and a first channel is formed between the upper material pipe 72 and the lower material pipe 73.

[0077] In a preferred embodiment, the lower material pipe 73 includes a bottom pipe structure 731 and a first funnel structure 732 connected to the top of the bottom pipe structure 731, with the larger end of the first funnel structure 732 facing upwards; the upper material pipe 72 includes an upper pipe structure 721 and a second funnel structure 726 sleeved on the outside of the upper pipe structure 721, with a plurality of protrusions 722 arranged circumferentially on the outer wall of the upper pipe structure 721, and a first gap 723 between adjacent protrusions 722, the outer surface of the protrusions 722 being inclined corresponding to the first funnel structure 732. Surface 724, the lower part of the upper tube structure 721 is inserted into the bottom tube structure 731, and there is a second gap 725 between the outer wall of the upper tube structure 721 and the inner wall of the bottom tube structure 731; the large end of the second funnel structure 726 faces the first funnel structure 732 and can cover the large end of the first funnel structure 732; there is a third gap 741 between the first funnel structure 732 and the second funnel structure 726; the third gap 741, the first gap 723 and the second gap 725 are interconnected to form the first channel.

[0078] In a preferred embodiment, a distance sensor 800 is installed inside the fabric tube 7, and the distance sensor 800 measures distance downwards; a crash box 801 is also installed on the inner side wall of the fabric tube 7, and the crash box 801 is at least partially located above the distance sensor 800.

[0079] In a preferred embodiment, the ranging sensor 800 is connected to a first wire; the first wire includes a power line and a signal line, which extend from the outside of the fabric tube 7 into the inside of the fabric tube 7 through a first channel.

[0080] like Figure 21 As shown, a wire hole 803 is provided through the side wall of the upper tube structure 721. The wire hole 803 corresponds to the height of the anti-collision box 801 and is connected to the internal cavity of the anti-collision box 801.

[0081] The first wire passes through the third gap 741 and the wire hole 803 in sequence and then extends into the anti-collision box 801 to connect with the ranging sensor 800. This effectively avoids direct contact between the power line and signal line and the stone, and effectively ensures the service life of the power line and signal line.

[0082] The entire assembly formed by the ranging sensor 800 and the anti-collision box 801 can move radially along the fabric tube 7.

[0083] During the initial distance measurement, the distance sensor 800 and the anti-collision box 801 extend into the material distribution pipe 7 for measurement. During the subsequent filling operation, the distance sensor 800 and the anti-collision box 801 are moved radially along the material distribution pipe 7 to the outside of the upper pipe structure 721 and the inside of the first funnel structure 732. This more effectively reduces the obstruction of the distance sensor 800 and the anti-collision box 801 to the stone material and further improves their service life. Preferably, the distance sensor 800 and the anti-collision box 801 are moved radially along the material distribution pipe 7 by a gear and rack mechanism. The rack is connected to both the ranging sensor 800 and the anti-collision box 801 via a cylindrical support. The rack is arranged radially along the fabric distribution tube 7. A motor capable of operating underwater drives the gear to rotate, causing the gear and rack to engage. Holes are opened on the side wall of the fabric distribution tube 7, and a pipe fitting structure adapted to the diameter of the hole is welded to the outside of the hole. Through the engagement of the gear and rack, the cylindrical support can be moved radially relative to the pipe fitting structure along the fabric distribution tube 7, thereby enabling both the ranging sensor 800 and the anti-collision box 801 to move radially along the fabric distribution tube 7.

[0084] An opening is made in the side wall at the lower part of the fabric distribution tube 7 and a collision avoidance box 801 is installed. A ranging sensor 800 with underwater ranging function is installed in the collision avoidance box 801, preferably an acoustic sensor. The power line and signal line connected to the acoustic sensor are led out of the fabric distribution tube 7 and led out of the water surface along the fabric distribution tube 7 and connected to the signal receiver of the working platform.

[0085] After the screed completes its underwater positioning, it is adjusted to a suitable elevation. Then, the material placement pipe 7 moves, and the underwater ranging sensor 800 measures the water depth data in real time and sends the data signal back to the signal receiver at the water surface of the screed. The data is displayed on the operating interface. By moving the screed, it continuously collects water depth information and finally forms a chart with position and water depth information. This allows the thickness of the underwater screed layer to be determined, which can guide the control of the volume and selection of the specifications of the stone material during subsequent screed placement.

[0086] Example 2 like Figure 1-24 As shown in the figure, the multi-degree-of-freedom adjustable underwater leveling machine described in this embodiment includes the underwater leveling layer thickness monitoring and recording device described in embodiment 1, and the material distribution pipe 7 can move laterally and longitudinally.

[0087] In a preferred embodiment, the multi-degree-of-freedom adjustable underwater leveling machine includes a first main frame 2 and a second main frame 1. The first main frame 2 and the second main frame 1 achieve walking motion of the underwater leveling machine through at least four first vertical lifting legs 31 and at least four second vertical lifting legs 32, wherein: The first main frame 2 includes two spaced-apart first longitudinal beams 22, and a first crossbeam 21 is connected between the ends of the two first longitudinal beams 22 on the same side. The first crossbeam 21 and the first longitudinal beam 22 form a circle. The second main frame 1 includes four arrayed end structures 13. A second longitudinal beam 12 is connected between adjacent end structures 13 along the longitudinal direction, and a second transverse beam 11 is connected between adjacent end structures 13 along the transverse direction. The second longitudinal beam 12 is sleeved on the outside of the corresponding first longitudinal beam 22, and the first longitudinal beam 22 can move relative to the second longitudinal beam 12 along the length direction. The first transverse beam 21 is located outside the second transverse beam 11, preferably arranged in parallel.

[0088] The end structure 13 has a first hole 131 extending through the length of the first longitudinal beam 22. A transverse frame 33 is provided in the first hole 131 and is fitted onto the first longitudinal beam 22. The transverse frame 33 can slide with the first longitudinal beam 22 through the longitudinal telescopic mechanism 5. The transverse frame 33 slides with the end structure 13 along the length of the second crossbeam 11 through the transverse telescopic mechanism 4. The transverse frame 33 and the end structure 13 are relatively limited along the direction of the first longitudinal beam 22, preferably by a key and groove engagement.

[0089] At least four first vertical lifting outriggers 31 are supported and connected to the second main frame 1; At least four second vertical lifting outriggers 32 are supported and connected to the first main frame 2.

[0090] The multi-degree-of-freedom adjustable underwater leveling machine described in this application, when in use, by setting a transverse frame 33 between the end structure 13 and the first longitudinal beam 22, and based on the sliding cooperation between the first longitudinal beam 22 and the transverse frame 33 along the length direction of the first longitudinal beam 22, the relative movement between the first longitudinal beam 22 and the end structure 13 in the longitudinal direction is realized, thereby achieving the purpose of the first vertical lifting leg 31 and the second vertical lifting leg 32 walking movement; 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.

[0091] 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.

[0092] The second longitudinal beam 12 has a first through hole 121 corresponding to the first hole 131, and the first longitudinal beam 22 passes through the first hole 131 and the first through hole 121 on the corresponding side. Based on the sliding engagement of the transverse frame 33 with the end structure 13 along the radial direction of the first hole 131, the first longitudinal beam 22 is inserted into the second longitudinal beam 12, so that the first longitudinal beam 22 and the second longitudinal beam 12 form an inner and outer nested relationship, which effectively reduces the overall horizontal arrangement space formed by the first longitudinal beam 22 and the second longitudinal beam 12, so that the lateral dimensions of the bidirectional walking underwater leveling machine can be made smaller.

[0093] A preferred embodiment is that the second longitudinal beam 12 is preferably 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.

[0094] In a preferred embodiment, the second crossbeam 11 is detachably connected to the end structure 13 via a bolt assembly.

[0095] 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.

[0096] 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].

[0097] In a preferred embodiment, one side of the first hole 131 has a first sidewall 132, and the transverse frame 33 has a first gap 114 with the first sidewall 132. The transverse telescopic mechanism 4 can drive the transverse frame 33 away from or closer to the first sidewall 132, so as to achieve the purpose of the transverse frame 33 slidingly engaging with the end structure 13 along the radial direction of the first hole 131. At the same time, the opposite sidewalls on both sides of the first hole 131 [one of which is the first sidewall 132] also have a limiting effect on the transverse frame 33.

[0098] 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.

[0099] 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.

[0100] The lateral telescopic mechanism 4 is connected between the end structure 13 and the transverse frame 33. The lateral telescopic mechanism 4 can extend and retract along the length of the second crossbeam 11. The lateral telescopic mechanism 4 is preferably a telescopic hydraulic cylinder or a pneumatic cylinder. The lateral telescopic mechanism 4 can drive the transverse frame 33 to reciprocate relative to the end structure 13.

[0101] More preferably, the lateral telescopic mechanism 4 can drive the lateral frame 33 away from or closer to the first sidewall 132.

[0102] In a preferred embodiment, 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 to 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.

[0103] In a preferred embodiment, the first transverse support gantry 42 is detachably connected to the outer wall of the end structure 13 via pins and / or bolts. This facilitates installation and transportation, as well as the installation and commissioning of the transverse telescopic mechanism 4.

[0104] 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.

[0105] The longitudinal telescopic mechanism 5 is connected between the second main frame 1 and the transverse frame 33. The longitudinal telescopic mechanism 5 can extend and retract along the length direction 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 direction of the first hole 131. The longitudinal telescopic mechanism 5 is preferably a telescopic hydraulic cylinder or a pneumatic cylinder.

[0106] 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, and the longitudinal telescopic mechanism 5 is connected between the first longitudinal support 51 and the second longitudinal support 52. The first longitudinal support 51 is preferably located within the first gap 114.

[0107] A first transverse through hole 136 is provided on the side wall of the first hole 131 away from the first crossbeam 21. A first transverse support frame 42 is provided outside the first transverse through hole 136. One end of the transverse telescopic mechanism 4 is connected to the first transverse support frame 42, and the other end passes through the first through hole 211 and is connected to the transverse frame 33.

[0108] In a preferred embodiment, the first longitudinal beam 22 is provided with a first vertical through hole 221, and the second vertical lifting outrigger 32 includes a second vertical telescopic mechanism 321 and a second vertical support gantry 223 disposed above the first vertical through hole 221. The second vertical support gantry 223 is detachably connected to the first longitudinal beam 22 by a pin or bolt group. The upper end of the second vertical telescopic mechanism 321 is connected to the second vertical support gantry 223, and the lower end is vertically slidably engaged with the first vertical through hole 221. The second vertical telescopic mechanism 321 is preferably a hydraulic cylinder.

[0109] In a preferred embodiment, a second vertical support gantry 223 is provided on the upper part of the first vertical through hole 221 to serve 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, this method can effectively lower the center of gravity of the first longitudinal beam 22 with less increase in structural weight, thereby effectively lowering the center of gravity of the entire structure 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.

[0110] In a preferred embodiment, a support beam 14 protrudes from one side of the second crossbeam 11 near the first crossbeam 21, and the support beam 14 has a second vertical through hole 141. A first vertical lifting leg 31 is connected to the support beam 14. The first vertical lifting leg 31 includes a first vertical telescopic mechanism 311 and a first vertical support gantry 312 disposed above the second vertical through hole 141. Both ends of the first vertical support gantry 312 are detachably connected to the support beam 14 via pins. The upper end of the first vertical telescopic mechanism 311 is connected to the first vertical support gantry 312, and the lower end is vertically slidingly engaged with the second vertical through hole 141. The first vertical telescopic mechanism 311 is preferably a hydraulic cylinder.

[0111] The second vertical lifting leg 32 and the first vertical lifting leg 31 preferably have the same structure.

[0112] Preferably, 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, so as not to interfere 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 in the lateral and vertical directions and become 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. The support telescopic structure includes hydraulic cylinders that are connected circumferentially along the first longitudinal beam 22 and are evenly arranged on the outer wall of the first longitudinal beam 22.

[0113] 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.

[0114] 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.

[0115] In a preferred embodiment, the fabric tube 7 includes an upper fabric tube 72 and a lower fabric tube 73: The upper material pipe 72 is connected above the lower material pipe 73, and there is a first channel between the upper material pipe 72 and the lower material pipe 73; In a preferred embodiment, the upper feed tube 72 is inserted into the lower feed tube 73.

[0116] In a preferred embodiment, the lower material pipe 73 includes a bottom pipe structure 731 and a first funnel structure 732 connected to the top of the bottom pipe structure 731, wherein the large end of the first funnel structure 732 is disposed facing the upper material pipe 72. The upper tube 72 includes an upper tube structure 721. A plurality of protrusions 722 are arranged circumferentially on the outer wall of the upper tube 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 tube structure 721 is inserted into the bottom tube structure 731, and there is a second gap 725 between the outer wall of the upper tube structure 721 and the inner wall of the bottom tube structure 731, which is connected to the first gap 723.

[0117] 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.

[0118] All of the lower lugs 734 are located near the large opening end of the first funnel structure 732.

[0119] In a preferred embodiment, the upper material 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 by a first gap 723. The third gap 741, the first gap 723 and the second gap 725 form the first channel.

[0120] The upper tube structure 721 has a first block 720 disposed on the outer side of the portion below the first funnel structure 732, and 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 material tube 73.

[0121] 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.

[0122] In a preferred embodiment, the fabric tube 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: The lower material pipe 73 is connected to a longitudinal moving mechanism 9, which can drive the material distribution pipe 7 to move along the length direction of the first longitudinal beam 22.

[0123] 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 material distribution tube 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 material distribution tube 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 material tube 73.

[0124] Preferably, the material pipe support 92 is sleeved and connected to the outside of the material distribution pipe 7.

[0125] In a preferred embodiment, the lower material tube 73 moves laterally relative to the second crossbeam 11 via a lateral moving mechanism 8.

[0126] In a preferred embodiment, the lateral movement mechanism 8 includes a second drive motor 84, a meshing second gear 82 and a second rack 83, and two parallel lateral rails 81 mounted on the second crossbeam 11. Both the second rack 83 and the lateral 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 lateral roller 86 is provided at the end of the longitudinal support 91, and the lateral roller 86 rolls in cooperation with the lateral rails 81.

[0127] When the longitudinal support 91 is provided, the lateral moving mechanism 8 drives the longitudinal support 91 and the second crossbeam 11 to move laterally, thereby achieving the purpose of the lower material tube 73 moving laterally relative to the second crossbeam 11.

[0128] The lateral movement mechanism 8 includes a meshing second gear 82 and a second rack 83, as well as two parallel lateral rails 81 mounted on the second crossbeam 11, and a second drive motor 84, which drives the second gear 82 and the second rack 83 to mesh and rotate.

[0129] 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.

[0130] In a preferred embodiment, a compressed air drainage chamber 112 is provided inside the second crossbeam 11 for leveling the bidirectional underwater screed and controlling its buoyancy and descent. Simultaneously, integrating the second crossbeam 11 and the compressed air drainage chamber 112 reduces the overall weight of the transverse and longitudinal walking mechanism.

[0131] like Figure 22 As shown, at least two compressed air drainage chambers 112 are provided inside the second crossbeam 11. A partition 1121 is provided between adjacent compressed air drainage chambers 112. A water passage hole 1122 is provided on the partition 1121. An inlet / outlet 1123 is provided at the bottom of each compressed air drainage chamber 112. Preferably, a sealing door can be provided at the 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 can be omitted at the inlet / outlet 1123.

[0132] The compressed air drainage chamber 112 is used to level the multi-degree-of-freedom adjustable underwater leveler underwater and to control the floating and sinking of the multi-degree-of-freedom adjustable underwater leveler.

[0133] Two spaced-apart second crossbeams 11 are provided, and a compressed air drainage chamber 112 is provided inside the second crossbeam 11. Since the compressed air drainage chamber 112 is provided inside the second crossbeam 11, the second crossbeam 11 and the compressed air drainage chamber 112 are integrated into one unit, thereby achieving the purpose of reducing the weight of the underwater leveling machine.

[0134] 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.

[0135] 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.

[0136] 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: 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 placing pipe 7, the lateral moving mechanism 8, and the longitudinal moving 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 placing pipe 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.

[0137] 2. When the whole machine needs to drain water, the measuring tower 6 is lowered. First, the upper material pipe 72 and the lower material pipe 73 of the material distribution pipe 7 are lifted away 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.

[0138] The top of the measuring tower 6 is equipped with a GPS or Beidou positioning system.

[0139] 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.

[0140] 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.

[0141] Preferred method 1: also includes the following steps for launching a multi-degree-of-freedom adjustable underwater leveler: 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.

[0142] Preferred method 2: This also 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 material pipe 73 at the bottom of the first platform, the slope extends to the bottom of the water. The multi-degree-of-freedom adjustable underwater screed is installed on the material pipe 73 at the bottom of the first platform. 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 these 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.

[0143] In a preferred embodiment, before construction, the following installation steps for the multi-degree-of-freedom adjustable underwater leveling machine are included: B1. Prepare the site for assembly; transport the components of the walking underwater leveling machine to the installation site, while taking into account the working conditions at the installation site to avoid the hydraulic system and electrical control system being submerged 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 the first vertical lifting legs 31 and the transverse telescopic mechanism 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, the first crossbeam 21 being positioned... B6. Install a material distribution pipe 7, a longitudinal moving mechanism 9, and a lateral moving mechanism 8 between the two second crossbeams 11. The longitudinal moving mechanism 9 can drive the material distribution pipe 7 to move along the length direction of the first longitudinal beam 22; the lateral moving mechanism 8 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 a measuring tower 6 on the top of the end structure 13; B8. Install the hydraulic system and electrical system of the whole machine, and then debug the whole machine and conduct a land simulation experiment.

[0144] like Figures 16-17As shown in this embodiment, a multi-degree-of-freedom adjustable underwater leveling machine has a measuring tower 6 and a drive mechanism 61 mounted on the top of at least two end structures 13 on the same side. The drive mechanism 61 can rotate the measuring tower 6 from horizontal to vertical, and vice versa. During transportation or launching, setting the measuring tower 6 to a horizontal position effectively reduces its impact on the underwater leveling machine's center of gravity and eccentricity during transport. Then, during launching, the measuring tower is rotated from horizontal to vertical to suit construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater leveling machine is effectively improved while adapting to construction conditions.

[0145] In a preferred embodiment, part of the end structure 13 is fitted with a bracket 62 that is hinged to the measuring tower 6, and 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.

[0146] 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 pneumatic cylinder. This allows for the rotation of the measuring tower 6 to be achieved using a first telescopic member with a smaller diameter, reducing the weight of the underwater leveling machine.

[0147] In a preferred embodiment, the drive mechanism 61 includes a first telescopic member, and the bracket 62 includes bracket units 621 arranged radially at intervals along the second longitudinal beam 12. Each bracket unit 621 is mounted on the top of the end structure 13, and there is a gap 622 between two bracket units 621.
