Description

Technical Field

[0001] The invention relates to the technical field of water riprap operations, in particular to a riprap ship with a symmetrical stone bunker. Background Art

[0002] Water riprap is a method of engineering construction by throwing stones in a water environment. It is often used in water conservancy projects, waterway regulation, breakwater construction and other fields.

[0003] Patent publication number CN107953976B discloses a riprap ship with symmetrical stone bunkers, comprising: a hull having a control cabin, with stone bunkers symmetrically arranged on either side of the control cabin. The stone bunkers have a chamber to accommodate stones of various sizes and types, and the bottom of the chamber is funnel-shaped, which can automatically unload the stones. A conveyor belt system is provided at the midship portion of the hull, corresponding to each of the two stone bunkers, which can automatically transport the stones from the stone bunkers to the control cabin, and each stone bunker can operate independently. The hull is symmetrically provided with a dynamic positioning (DP) system cabin on both sides of the control cabin, which can position the hull; and a stone conveying unit, which is arranged in the control cabin and connected to the conveyor belt system; and an inclined pipe drop unit, which includes a pipe holding compensation device, which is arranged on the side of the hull. The inclined pipe drop unit also includes a drop pipe, which is installed on the pipe holding compensation device. The pipe holding compensation device has the ability to position the drop pipe and allows the drop pipe to be connected to the stone conveying unit. The conveyor belt system cooperates with the stone conveying unit to automatically convey stones to the drop pipe in an automatic dropping method, and the two stone cabins are symmetrically arranged on both sides of the control cabin. Stones of different sizes and types can be stored separately in the multiple self-unloading storage chambers. Then, according to demand, one of the stone cabins can be selected to operate alone or the stone cabins can operate simultaneously. The dynamic positioning (DP) system cabin and the pipe-holding compensation device are used to position the hull and the drop pipe respectively, so that the stone-throwing ship with symmetrical stone cabins can complete high-precision stone-throwing operations, thereby making the stone-throwing ship with symmetrical stone cabins have the advantages of saving materials, time, labor and money.

[0004] In the above technical solution, the riprap is on the water surface when working. Therefore, environmental changes on the water surface, such as wind and waves, will cause the riprap to swing during operation. Although the oblique drop tube unit can be aligned with the construction pit under the adjustment of the pipe-holding compensation device, when the riprap swings with the wind and waves, the oblique drop tube unit is in the working stage, so there is still a risk of inaccurate riprap. Therefore, a riprap with a symmetrical stone compartment is urgently needed to solve the above problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) A symmetrical stone bunker riprap ship, wherein a mechanical arm mounted on the hull mechanism pushes the first positioning assembly held by the mechanical arm toward the marker column, so that the first half-ring mechanism and the second half-ring mechanism are docked, and then the second half-ring mechanism drives the first half-ring mechanism to move down along the marker column into the construction pit, and the traction rope on the first half-ring mechanism is connected to the pipe-dropping mechanism, thereby cooperating with the pipe-holding equipment to correctly introduce the pipe-dropping mechanism into the construction pit, thereby improving the accuracy of riprap.

[0015] (2) A riprap ship with a symmetrical stone bunker, wherein the telescopic column of the first lock is extended by electric control, thereby pushing the lever along the notch, so that the cross section of the lock block and the arc plate are flush, so that the first lock and the second lock are smoothly inserted, and then the telescopic column is retracted to make the lever slide along the notch, at which time the gap of the lock block and the gap of the arc plate are staggered, thereby completing the automatic locking and improving the convenience of docking.

[0028] The second positioning assembly includes a displacement mechanism 7, which includes a main ring 701 that is movably connected to the column through a bearing, and through grooves 702 are formed on three circumferential sides of the main ring 701; Each through slot 702 is provided with a moving assembly, which includes a moving rod 703 inserted through the through slot 702, and rod grooves 704 adapted to fit the bayonet 402 are provided on both sides of the moving rod 703; Power components for controlling the movement of the shift rod 703 are symmetrically arranged on both sides thereof, and the power components are arranged in the through slot 702.

[0029] The lower ends of the shift rods 703 of the three power assemblies are commonly fixed with a second half-ring mechanism 8 symmetrical to the first half-ring mechanism 4 , and the second half-ring mechanism 8 is adapted to fit the marker column of the construction pit.

[0030] The outer ring of the second half-ring mechanism 8 is provided with second lock buckles 9 respectively mounted on both ends thereof and adapted to engage with the first lock buckle 5. The second lock buckle 9 is symmetrical with the first lock buckle 5 on the same side. The first lock buckle 5 includes a lock buckle chamber 501 fixedly connected to the first half ring 401, a semi-circular arc plate 502 fixedly connected to the inner side of the port of the lock buckle chamber 501, a notch 503 is formed on the side of the arc plate 502 facing away from the port of the lock buckle chamber 501, a guide block 504 is fixedly connected to the side of the arc plate 502 close to the port of the lock buckle chamber 501, a flat plate 505 is fixedly connected to the end of the arc plate 502 facing away from the port of the lock buckle chamber 501, a semi-cylindrical locking block 506 is adapted to be fitted in the arc plate 502, a lever 507 adapted to be inserted through the notch 503 is fixedly connected to the side of the locking block 506, the end of the lever 507 is movably hinged to a telescopic column 508 via a rotating shaft, and the end of the telescopic column 508 away from the lever 507 is movably hinged to the lock buckle chamber 501 via a rotating shaft; A sealing strip 509 is fixedly nested on the outer side of the port of the locking compartment 501; The structure of the second lock buckle 9 is centrally symmetrical to that of the first lock buckle 5 , and the telescopic column 508 of the first lock buckle 5 is electrically controlled.

[0031] The working principle of the present invention is as follows: The second positioning assembly is installed on the marker post of the construction pit, and the roller 707 in the power compartment 705 rotates under the drive of the rotator 708. The rotator 708 adapts to the plug-in rod slot 704, so that the power assemblies on both sides of the shift rod 703 abut it, so that the shift rod 703 slides up and down along the friction block 706, and then the second half-ring mechanism 8 set in contact with the marker post can slide along it. When the hull mechanism 1 approaches the construction pit, the mechanical arm 109 carried on the hull mechanism 1 pushes the first positioning assembly clamped by it toward the marker post, so that the first half-ring mechanism 4 and the second half-ring mechanism 8 are docked, and then the second half-ring mechanism 8 drives the first half-ring mechanism 4 to move down along the marker post into the construction pit, and the traction rope 405 on the first half-ring mechanism 4 is connected to the pipe-dropping mechanism 2, so that the pipe-dropping mechanism 2 is correctly introduced into the construction pit in cooperation with the pipe-holding equipment 106, thereby improving the accuracy of stone throwing.

[0032] Second lock buckles 9 are installed at both ends of the outer ring of the second half-ring mechanism 8, and first lock buckles 5 are installed at both ends of the outer ring of the first half-ring mechanism 4. When the first half-ring mechanism 4 is docked with the second half-ring mechanism 8 through the mechanical arm 109, the guide block 504 of the first lock buckle 5 is correspondingly inserted into the second lock buckle 9. Similarly, the second lock buckle 9 is inserted into the first lock buckle 5. The telescopic column 508 of the first lock buckle 5 is extended by electric control, thereby pushing the lever 507 along the notch 503, so that the cross section of the lock block 506 and the arc plate 502 are flush, so that the first lock buckle 5 and the second lock buckle 9 are smoothly inserted. Then, by contracting the telescopic column 508, the lever 507 slides along the notch 503. At this time, the gap of the lock block 506 and the gap of the arc plate 502 are staggered with each other, thereby completing automatic locking and improving docking convenience.

[0033] A sealing strip 509 is embedded in the docking port of the first lock buckle 5 and the second lock buckle 9, and the telescopic column 508 of the first lock buckle 5 is set inside the lock buckle compartment 501 to prevent the telescopic column 508 from contacting the water source and improve the service life.

[0034] The traction mechanism 3 carried on the bottom warehouse 101 is connected to the second joint 403 of the first half-ring mechanism 4 through the iron chain 303, and the two traction mechanisms 3 are arranged so as to be connected to the marker to form a triangular stable structure. When wind and waves appear on the sea surface, the hull mechanism 1 forms a link with the marker of the construction pit through the connection between the first half-ring mechanism 4 and the second half-ring mechanism 8. Even if the hull mechanism 1 is driven by wind and waves, it can still float around the marker, so that the riprap is always carried out around the construction pit, thereby improving the stability of the riprap.

[0035] The traction rope 405 of the first half-ring mechanism 4 is connected to the lower end of the outer tube 201, so that when the first half-ring mechanism 4 slides down along the marker column into the construction pit under the drive of the second half-ring mechanism 8, the pipe-dropping mechanism 2 is inserted into the water under the drive of the pipe-holding device 106, and the traction rope 405 can follow the direction of the first half-ring mechanism 4 to pull the pipe-dropping mechanism 2. When the hull mechanism 1 fluctuates in position during the stone throwing process, the traction of the traction rope 405 can compensate for the posture deviation of the hull mechanism 1, thereby improving the stone throwing positioning accuracy.

[0036] The outer tube 201 is pulled by the traction rope 405 to approach the marker position of the construction pit. When the area of the construction pit is large, the winch 107 fixedly connected to the middle of the upper surface of the clamping plate 102 is used to reel in the steel cable 108, thereby pulling the inner tube 203 upward along the slot 202, so that the guide plate 204 is away from the lower end of the outer tube 201, guiding the stone in the direction away from the marker, thereby changing the lateral distance of the stone throwing and improving the flexibility of the stone throwing.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
