the measuring and positioning structure 17 including a measuring frame 171 and at least one positioning structure 173, one end of the measuring frame 171 is rotatably connected to the support structure 11, and the positioning structure 173 is fixed to the other end of the measuring frame 171.

The support structure 11 of the auto-paver system 100 according to the technical scheme of the present disclosure is supported on the water bottom surface, and the transport structure 13 is slidably connected to the support structure 11. The support structure 11 can limit a movement track of the transport structure 13 and enable the transport structure 13 to move relatively close to the water bottom surface. The distributing structure 155 is connected to the transport structure 13, so that the distributing structure 155 can also move at a position close to the water bottom surface under the drive of the transport structure 13. Materials are input through the feed port 1551 of the distributing structure 155 and output through the discharge port 1553, and the discharge port 1553 is extended towards the water bottom surface. As the distributing structure 155 is close to the water bottom surface, the materials output by the distributing structure 155 can fall to a designated position of the water bottom surface through a short distance, and the whole laying process is hardly influenced by water flows, so that the laying position of the materials on the water bottom surface is accurate.
Furthermore, the support structure 11 is also provided with a measuring and positioning structure 17. The positioning structure 173 of the measuring and positioning structure 17 is used for acquiring self position information of the measuring and positioning structure 17. Position information of the support structure 11 can be obtained by combing the self position information with the known form of the measuring frame 171, and the support structure 11 can be accurately placed at a designated position according to the obtained position information of the support structure 11, so that the distributing position of the distributing structure 155 is more accurate.
The measuring frame 171 is rotatably connected to the support frame 11, so that an overall height of the measuring and positioning structure 17 can be adjusted, thereby achieving the purpose of not occupying the navigation channel.
Specifically, the measuring frame 171 is configured to rotate relative to the support structure 11 to have a first state and a second state, the positioning structure 173 on the measuring frame 171 in the first state is higher than the positioning structure 173 on the measuring frame 171 in the second state. In the first state, the detection effect of the positioning structure 173 is more accurate, and in the second state, the overall height of the measuring and positioning structure 17 is reduced, so that the paver 10 achieves the purpose of less or no obstruction to the navigation channel.

Referring to Figs. 1 and 2, in one embodiment of the present disclosure, the upright post 1711 is provided with a first connecting piece 172, the first connecting piece 172 is provided with a first connecting hole, the support structure 11 is provided with a second connecting piece 182 matched with the first connecting piece 172, the second connecting piece 182 is provided with a second connecting hole matched with the first connecting hole, and a pin shaft 121 is passed through the first connecting hole and the second connecting hole matched with the first connecting hole to rotatably connect the upright post 1711 and the support structure 11. Under the restriction of the pin shaft 121, the upright post 1711 can rotate relative to the support structure 11, and the rotating structure is simple.
In one embodiment of the present disclosure, the paver 10 further includes a limiting structure, which is configured to limit and fix the upright post 1711 and the support structure 11 when the upright post 1711 is rotated to form an included angle with the support structure 11.
Specifically, the upright post 1711 is rotatably connected to a side of the support structure 11 facing away from the water bottom surface. Therefore, the upright post 1711 is rotated only on the side of the support structure 11 facing away from the water bottom surface during the rotation of the support structure 11. The upright post 1711 is rotated to form an included angle with the support structure 11, which is greater than zero, that is, the position where the positioning structure 173 is located is relatively high with respect to the water bottom surface. In this state, the positioning detection effect of the positioning structure 173 is better, that is, the first state is reached. When the angle between the upright post 1711 and the support structure 11 is zero, that is, it is measured that the whole positioning structure 17 is at a lowest position with respect to the water bottom surface. In this state, the paver 10 can be completely accommodated in the base groove to reach the second state without blocking the navigation channel.
In one embodiment of the present disclosure, the limiting structure includes a third connecting piece 174 arranged on the upright post 1711 and a fourth connecting piece 184 arranged on the support structure 11, the third connecting piece 174 is provided with a third connecting hole, the fourth connecting piece 184 is provided with a fourth connecting hole matched with the third connecting hole, a bolt 123 is detachably passed through the third connecting hole and the fourth connecting hole, to detachably connect the upright post 1711 and the support structure 11, and when the upright post 1711 is rotated to form an included angle with the support structure 11 the bolt 123 is configured to limit and fix the upright post 1711 and the support structure 11.
When the bolt 123 is passed through the third connecting hole and the fourth connecting hole, to limit the upright post 1711 and the support structure 11, so that the bolt 123 is configured to fix the upright post 1711 and the support structure 11 when the upright post 1711 is rotated to form an included angle with the support structure 11.
Referring to Figs. 3 and 4, in one embodiment of the present disclosure, the third connecting member 174 is disposed at an end of the upright post 1711 remote from the positioning structure 11, and the rotating joint between the upright post 1711 and the support structure 11 is spaced apart from the third connecting member 174 along a length direction of the upright post 1711.
Specifically, when the upright post 1711 is rotated to a plane perpendicular to the support structure 11, the end of the upright post 1711 is fixed by the limiting structure to reach the first state. An axial direction of the bolt 174 of the limiting structure is consistent with an axial direction of the upright post 1711. A portion of the upright post 1711 near the limiting structure is rotatably connected with the support structure 11. Specifically, the rotating shaft of the upright post 1711 is perpendicular to the axial direction of the upright post 1711, that is, the axial direction of the pin shaft 121 is perpendicular to the axial direction of the upright post 1711.
An opening is formed at the end of the upright post 1711 remote from the positioning structure 173, the opening is extended along the axial direction of the upright post 1711, the third connecting plate 174 is defined as two parallel plates, the plate surfaces of the two plates are perpendicular to the axial direction of the upright post 1711, one plate is positioned in the opening, the other plate is configured to block the opening, and the two plates are provided with a third connecting hole, the two connecting holes are matched with each other. The support structure 11 is provided with a fourth connecting plate 174 perpendicular to the axis of the upright post 1711 when the upright post 1711 is rotated to be perpendicular to the support structure 11. The bolt 174 is passed through the fourth connecting hole and the two third connecting holes along the axis direction of the upright post 1711. The limiting structure can limit the rotation of the upright post 1711 on the support structure 11.
When the bolt 174 on the limiting structure is pulled away, the upright post 1711 can rotate on the support structure 11 to make the measuring and positioning structure 17 to be in a lower position.
In one embodiment of the present disclosure, the measuring and positioning structure 17 includes two positioning structures 173, the measuring frame 171 includes two upright posts 1711 which are oppositely arranged, a connecting bracket 1713 is connected between the two upright posts 1711, and the two positioning structures 173 are respectively fixed to the two upright posts 1711.
Under the common positioning of the two positioning structures 173, the obtained position of the support structure 11 is more accurate, and the two upright posts 1711 are connected by the connecting bracket 1713, so that the two upright posts 1711 of the measuring frame 171 can rotate relative to the support structure 11 at the same time, and the structure is simple.
In one embodiment of the present disclosure, the connecting bracket 1713 includes a connecting beams 1713a connected with two upright posts 1711. A quantity of the connecting beams 1713a is two, and the two connecting beams 1713a are arranged in parallel.
The two connecting beams 1713a can connect the two uprights 1711 well, so that the two uprights 1711 can rotate at the same time, and the structure is simple.
In one embodiment of the present disclosure, the connecting bracket 1713 further includes a plurality of reinforcing rods 1713b, and the reinforcing rods 1713b are connected to an area enclosed by the two upright posts 1711 and the two connecting beams 1713a.
As the two upright posts 1711 are arranged in parallel with each other and the two connecting beams 1713a are arranged in parallel with each other, a rectangular area is formed between the two upright posts 1711 and the two connecting beams 1713a, and the connection between the two upright posts 1711 is more stable due to the arrangement of the reinforcing rods 1713b.
Referring to Fig. 3, a connecting plate is fixed at each joint of the two upright posts 1711 and the connecting beam 1713a adjacent to the positioning structure 173. One connecting plate is fixed at the middle of the other connecting beam 1713a. There are three reinforcing rods 1713b. Both ends of each reinforcing rod 1713b are connected to two connecting plates located on the two connecting beams 1713a. Therefore, the reinforcing bar 1713b can divide the rectangular area into a plurality of triangular areas. Based on the stability of the triangles, the arrangement of the reinforcing bar 1713b can make the connection of the two upright posts 173 more stable and reliable.
In one embodiment of the present disclosure, the support structure 11 includes a support frame 113 and a buoyancy column 18, the support frame 113 is supported on the water bottom surface, the buoyancy column 18 is convexly arranged on one side of the support frame 113 facing away from the water bottom surface, the transport structure 13 is slidably connected to the support frame 113, and the measuring frame 171 is rotatably connected to the buoyancy column 18.
The buoyancy column 18 is convexly arranged on one side of the support frame 113 facing away from the water bottom surface, so that the measuring frame 171 rotatably connected to the buoyancy column 18 is lifted by a distance in the direction facing away from the water bottom surface, so that when the measuring frame 171 is rotated to form a zero degree included angle with the support structure 11, the measuring frame 171 can abut against an end surface of the buoyancy column 18, so that the whole measuring and positioning structure 17 and the support frame 113 maintain a certain distance, and the measuring and positioning structure 17 cannot interfere with the transport structure 13 and the distributing structure 155 moving on the support frame 113. The buoyancy column 18 is a hollow cylinder, which has a certain floating effect on the underwater support structure 11, thus reducing the total weight of the support structure 11 and facilitating the change of the position of the support structure 11.
When the upright post 1711 is rotated to the first state, the upright post 1711 rotates until the axial direction of the upright post 1711 is consistent with the axial direction of the buoyancy column 18, and the upright post 1711 and the buoyancy column 18 partially overlap along the axial direction. One end of the upright post 1711 facing away from the positioning structure 173 is detachably connected to the buoyancy column 18 through the limiting structure, so that the positioning structure 173 positioned at the end of the upright post 1711 can reach the highest position. A portion of the upright post 1711 near the limiting structure is rotatably connected to a free end of the buoyancy column 18, and the free end is an end of the buoyancy column 18 facing away from the support frame 113. By pulling out the bolt of the limiting structure, one end of the upright post 1711 facing away from the positioning structure 173 is separated from the buoyancy column 18. The upright post 1711 is rotated to abut against the free end of the buoyancy column 18 and is parallel to the plane where the support structure 11 is located, to reach the second state. It is measured that the overall height of the positioning structure 17 is decreased, so that the paver 10 is integrally accommodated in the base groove.
In one embodiment of the present disclosure, in the first state, one end of the upright post 1711 fixed with the positioning structure 173 is extended out of the water surface, so that the positioning effect of the positioning structure 173 is better.
The positioning structure 173 is a GPS (Global Positioning System), specifically, a RTK (Real-time kinematic, Carrier Phase Difference Technology). The RTK can provide three-dimensional positioning results of the measured position in a specified coordinate system in real time and achieve centimeter-level accuracy. So that, the obtained position information of the support structure 11 is more accurate.
The support frame 113 includes two opposite first crossbeams 1131 and two opposite second crossbeams 1133. The first crossbeams 1131 and the second crossbeams 1133 are connected end to end. There are four buoyancy columns 18. Each buoyancy column 18 is arranged at one joint of the first crossbeam 1131 and the first second crossbeams 1133. The measuring structure 171 is rotatably connected to the two buoyancy columns 18 which are positioned on the same side. The support frame 113 also includes a plurality of support legs 16. The plurality of support legs 16 are symmetrically connected to the two first crossbeams and/or the two second crossbeams, and are supported on the water bottom surface. The first crossbeams 1131 and/or the second crossbeams 133 are provided with guide rails 111, and the transport structure 13 is slidably connected to the guide rails 111.
The paver 10 is supported on the water bottom surface by the support leg 16, and can directly perform laying and paving work under water. While the work platform of the existing floating leveling ship or the platform leveling ship with positioning piles is located on or above the water surface, and partial structural of the leveling ship needs to be adjusted according to the water depth. The auto-paver system 100 of the present disclosure can be suitable for requirements of different water depths, and has wide applicability.
The support leg 16 includes a driving part 162, a leg 161, and a connecting part 163. The driving part 162 is configured to drive the leg 161 and the connecting part 163 to move relative to each other in an up-down direction, so that the height of the support structure 11 on the water bottom surface can be adjusted, and the height of the distributing structure 155 on the water bottom surface can be adjusted, so that the distributing structure 155 can be applied to the bottom surfaces of the base grooves with different concavities and convexities, and the applicability range of the auto-paver system 100 of the present disclosure is wider.
Under the adjustment of the support leg 16, the distance between the lower surfaces of the first crossbeam 1131 and the second crossbeam 1133 and the water bottom surface is in a range of 800 mm to 2800 mm, so that a distance between the discharge port 1553 of the distributing structure 155 and the water bottom surface is in a range of 0 mm to 2000 mm. In this size range, when the auto-paver system 100 works, the paver 10 is close to the water bottom surface, so that the transport structure 13 slidably connected to the support frame 113 and the distributing structure 155 connected to the transport structure are close to the water bottom surface, and the material transported by the distributing structure 155 during the movement of the support frame 113 is short, so that the output process is less affected by water flows and the laying is accurate. That is, under the adjustment of the support leg 16, the distance between the support frame 113 and the water bottom surface (that is, the bottom surface of the base groove) can be adjusted between 800 mm and 2800 mm, so that the distance between the discharge port 1553 of the distributing structure 155 and the water bottom surface can be adjusted between 0 mm and 2000 mm.
The guide rail 111 can restrict the transport structure 13 to move along a certain track, so that the material distribution structure 155 can evenly lay the material in the area where the guide rail 111 can reach. The structure and shape of the guide rail 111 determine the laying trajectory of the distributing structure 155. The structure and shape of the guide rail 111 can be changed according to different requirements, so that the auto-paver system 100 can adapt to different working requirements. The rationality of the arrangement of the guide rail 111 can affect the smoothness of gravel laying on the water floor. Therefore, under the restriction of the guide rail 111, the track traveled by the transport structure 13, the shape of the discharge port 1553 of the distribution structure 155 and the amount of the laying material need to be well matched, so that the water bottom surface to be laid can achieve a required forming effect.
In one embodiment of the present disclosure, the guide rail 111 is disposed on the second crossbeam 1133, the transport structure 13 is slidably connected to the guide rail 111, and the support legs 16 are symmetrically connected to the two second crossbeams 1133.
Each support leg 16 can be adjusted separately, so that the height of the position where any support leg 16 is connected to the support frame 113 can be adjusted separately, thereby controlling the inclination angle of the support frame 113.
As the guide rail 111 is arranged on the second crossbeam 1133, the transport structure 13 and the distributing structure 155 are mainly carried by the second crossbeam 1133. So that, the support leg 16 is connected to the second crossbeam 1133, and the load-bearing capacity of the second crossbeam 1133 is stronger, the transport structure 13 and the distributing structure 155 can maintain high consistency during their movements on the guide rail 111, and the paving effect of the distributing structure 155 is better.
In one embodiment of the present disclosure, the guide rail 111 includes two symmetrically arranged longitudinal guide rails 1111 and two symmetrically arranged transverse guide rails 1113, the longitudinal guide rails 1111 are arranged in parallel with the first crossbeam 1131, and the transverse guide rails 1113 are arranged in parallel with the second crossbeam 1133. Referring to Fig. 1, in one embodiment, two symmetrically arranged transverse guide rails 1113 are respectively fixed to two second crossbeams 1133, and two longitudinal guide rails 1111 are slidably connected to the two transverse guide rails 1113. Specifically, one end of each longitudinal guide rail 1111 is slidably connected to one transverse guide rail 1113, and the other end of each longitudinal guide rail 1111 is slidably connected to another transverse guide rail 1113. The second crossbeam 1133 is provided with a drive motor and a chain arranged along an extension direction of the second crossbeam 1133. The chain is connected with the two longitudinal guide rails 1111. Under the drive of the motor, the chain is configured to drive the longitudinal guide rails 1111 to reciprocate along the transverse guide rails 1113 (i.e., to reciprocate along the extension direction of the second crossbeam 1133). It can be understood that the longitudinal guide rail 1111 can also be slidably connected to the transverse guide rail 1113 by other driving means, for example, a roller and a driving structure provided on the longitudinal guide rail. The driving structure is configured to drive the roller to roll on the transverse guide rail, so that the longitudinal guide rail can slide relative to the transverse guide rail on the transverse guide rail.
Before laying materials, or when the auto-paver system 100 restarts after a half-stopping, sludge may accumulate on the bottom surface of the base groove due to the influence of water flows. A sludge suction structure 145 needs to be arranged on the transport structure 13 to suck sludge, so as to prevent sludge from being mixed with crushed stones and affecting the supporting effect of the bottom surface of the base tank on the sinking pipe.
Referring to Fig. 6, in one embodiment of the present disclosure, the paver 10 further includes a sludge suction structure 145 connected to the transport structure 13, the sludge suction structure 145 is provided with a sludge discharge port 1453 and a sludge suction port 1451 extending in the direction towards the water bottom surface, and is provided with a sludge suction driving member communicating the sludge suction port 1451 and the sludge discharge port 1453.
