Description

Technical Field

[0001] This invention relates to the field of waterborne stone-throwing technology, specifically to a stone-throwing vessel with a symmetrical stone hopper. Background Technology

[0002] Waterborne rock dumping is a construction method that involves throwing stones into a water environment. It is commonly used in water conservancy projects, waterway improvement, and breakwater construction.

[0003] Patent CN107953976B discloses a quarrying vessel with symmetrical stone hoppers, comprising: a hull having a control cabin, on both sides of which are symmetrically arranged stone hoppers. Each stone hopper has a compartment for accommodating stones of various sizes and types, and the bottom of the compartment is funnel-shaped for automatic stone unloading. A conveyor belt system is provided between the two stone hoppers at the midship section of the hull, automatically transporting stones from the hopper to the control cabin. Each stone hopper can operate independently. The hull is symmetrically located on both sides of the control cabin, with a dynamic positioning (DP) system cabin on each side for positioning the hull; a stone conveying unit located in the control cabin and connected to the conveyor belt system; and an inclined pipe dropping unit, which includes a pipe clamping compensation device located on the side of the hull. The inclined pipe dropping unit also includes a dropping pipe installed on the pipe clamping compensation device, which has the ability to position the dropping pipe and connect the dropping pipe to the stone conveying unit. The automatic material unloading method, which automatically transports stones to the unloading pipe through the conveyor belt system and the stone conveying unit, and the two stone bins symmetrically arranged on both sides of the control cabin, can store stones of different sizes and types separately in the multiple self-unloading storage chambers. Then, according to the needs, one stone bin can be selected to operate alone or the stone bins can operate simultaneously. Furthermore, the dynamic positioning (DP) system and the pipe clamping compensation device are used to position the hull and the unloading pipe respectively, so that the stone-throwing vessel with symmetrical stone bins can complete the stone-throwing operation with high precision. Thus, the stone-throwing vessel with symmetrical stone bins has the advantages of saving materials, time, labor and money.

[0004] In the above-mentioned technical solution, the stone-throwing vessel is on the water surface during operation. Therefore, changes in the water environment, such as wind and waves, will cause the stone-throwing vessel to sway during operation. Although the inclined pipe-dropping unit can be aligned with the construction pit under the adjustment of the pipe-holding compensation device, the inclined pipe-dropping unit is in operation when the stone-throwing vessel is swaying with the wind and waves. Therefore, there is still a risk of inaccurate stone throwing. Therefore, there is an urgent need for a stone-throwing vessel with a symmetrical stone hopper to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a stone-throwing vessel with a symmetrical stone hopper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a symmetrical stone-carrying quarry stone-throwing vessel, comprising a hull structure, a first positioning component, and a second positioning component; The hull structure includes a bottom compartment, a clamping plate is fixedly mounted on the top of the bottom compartment, and stone conveying components are symmetrically arranged at both ends of the clamping plate; A pipe-holding device is fixedly connected to the upper side of the clamp plate between the two stone conveying components; The pipe-holding device is equipped with a pipe-dropping mechanism; A robotic arm is fixedly connected between the two stone bins and the clamping plate; Each of the stone bins is equipped with a traction mechanism on its front side.

A chain is fixedly connected between the second connector and the first connector on the same side. The second positioning component is installed on the marker post of the construction pit, and the hull mechanism is stabilized around the marker post of the construction pit by the first positioning component and the second positioning component.

[0007] As a preferred embodiment of the present invention, the stone conveying assembly includes a stone hopper fixedly connected between the bottom hopper and the clamping plate, and the stone conveying assembly also includes a stone conveying hopper fixedly connected to the clamping plate. The stone conveying hopper is connected to the stone hopper, and a conveyor for conveying stone to the drop pipe mechanism is movably installed on the upper surface of the stone conveying hopper.

[0008] As a preferred embodiment of the present invention, the tube dropping mechanism includes an outer tube, the outer tube having a half-tube structure, and a slot being provided on the upper end face of the outer tube; The tube lowering mechanism also includes an inner tube with an adapted insertion slot. The inner tube has a full tube structure, and a guide plate adapted to assemble the outer tube is fixedly connected to the lower end face of the inner tube. The guide plate has a half tube structure. The traction rope is fixedly connected to the lower end of the outer tube.

[0009] A winch is fixedly connected to the middle of the upper surface of the clamping plate. A steel cable is wound inside the winch. The end of the steel cable extends out of the winch and is fixedly connected to the upper end of the inner tube. The steel cable is connected to the side of the inner tube away from the outer tube.

[0010] As a preferred embodiment of the present invention, the first half-ring is provided with a bayonet on each end side.

[0011] The second positioning component includes a displacement mechanism, which includes a main ring that is movably sleeved on a marker post via a bearing, and the main ring has through slots on all three circumferential sides. Each of the through slots is provided with a moving component, the moving component including a moving rod that passes through the through slot, and the moving rod has rod slots on both sides that are adapted to fit and engage. The moving rod is symmetrically provided with power components for manipulating its movement on both sides. The power components are set in the through groove. Each power component includes a power chamber fixedly connected to the through groove. Friction blocks adapted to the insertion rod groove are fixedly connected to the middle of the upper and lower walls of the power chamber facing the moving rod. A roller adapted to the insertion rod groove is provided in the power chamber. A rotator fixedly connected in the power chamber is installed at the end of the rotating shaft of the roller.

[0012] The lower ends of the moving rods of the three power components are jointly fixed to a second semi-ring mechanism that is symmetrical to the first semi-ring mechanism. The second semi-ring mechanism is adapted to fit the marker post of the construction pit.

[0013] The outer ring ends of the second semi-ring mechanism are respectively equipped with second latches that are adapted to and engage with the first latch, and the second latches are symmetrical to the center of the first latch on the same side; The first latch includes a latch chamber fixedly connected to a first semi-ring. A semi-circular arc plate is fixedly connected to the inner side of the port of the latch chamber. A notch is opened on the side of the arc plate opposite to the port of the latch chamber. A guide block is fixedly connected to the side of the arc plate close to the port of the latch chamber. A flat plate is fixedly connected to the end of the arc plate opposite to the port of the latch chamber. A semi-cylindrical locking block is adapted to be fitted inside the arc plate. A lever adapted to be inserted through the notch is fixedly connected to the side of the locking block. A telescopic column is movably hinged to the end of the lever through a pivot. The end of the telescopic column away from the lever is movably hinged to the latch chamber through a pivot. A sealing strip is fixedly nested on the outside of the port of the locking compartment.

[0014] Compared with the prior art, the beneficial effects of the present invention are: A symmetrical stone-throwing vessel with a stone hopper uses a mechanical arm mounted on the hull to push the first positioning component it holds toward a marker post, causing the first and second semi-ring mechanisms to align. Subsequently, the second semi-ring mechanism drives the first semi-ring mechanism to move down along the marker post into the construction pit. Through the connection between the traction rope on the first semi-ring mechanism and the pipe-dropping mechanism, the pipe-holding equipment is used to correctly guide the pipe-dropping mechanism into the construction pit, improving the accuracy of stone throwing.

[0015] A symmetrical stone-carrying vessel has a telescopic column for the first locking mechanism that extends electrically to push a lever along a notch, making the cut surfaces of the locking block and the arc plate flush. This allows the first and second locking mechanisms to engage smoothly. Subsequently, by retracting the telescopic column, the lever slides along the notch, at which point the gaps in the locking block and the arc plate are staggered, thus completing the automatic locking and improving docking convenience.

[0016] A symmetrical stone-carrying vessel has sealing strips embedded at the docking ports of the first and second locks, and the telescopic column of the first lock is set inside the lock chamber to prevent the telescopic column from contacting the water source and improve its service life.

[0017] A symmetrical stone-carrying vessel, when there are waves on the sea, the hull structure is linked to the marker post of the construction pit through the connection of the first half-ring mechanism and the second half-ring mechanism. Even if the hull structure is moved by the waves, it can float around the marker post, so that the stone is always thrown around the construction pit, thus improving the stability of the stone throwing.

[0018] A symmetrical stone-carrying vessel has a pipe-dropping mechanism that is inserted into the water by a pipe-holding device. The traction rope can follow the first half-ring mechanism to guide the orientation of the pipe-dropping mechanism. If the position of the vessel mechanism fluctuates during the stone-dropping process, the traction rope can compensate for the attitude deviation of the vessel mechanism and improve the positioning accuracy of stone-dropping.

[0019] A symmetrical stone-throwing vessel, when the construction pit area is large, uses a winch fixedly connected to the middle of the upper surface of the clamp plate to wind up the steel cable, thereby pulling the inner tube upward along the slot, so that the guide plate moves away from the lower end of the outer tube and guides the stone away from the marker post, thus changing the lateral distance of the stone throwing and improving the flexibility of stone throwing.

[0029] The lower ends of the moving rods 703 of the three power components are jointly fixed to a second semi-ring mechanism 8, which is symmetrical to the first semi-ring mechanism 4. The second semi-ring mechanism 8 is adapted to fit the marker post of the construction pit.

[0030] The outer ring of the second semi-ring mechanism 8 is equipped with a second latch 9 that is adapted to and engages with the first latch 5 at both ends. The second latch 9 is symmetrical to the first latch 5 on the same side. The first latch 5 includes a latch chamber 501 fixedly connected to the first semi-ring 401. A semi-circular arc plate 502 is fixedly connected to the inner side of the port of the latch chamber 501. A notch 503 is opened on the side of the arc plate 502 away from the port of the latch chamber 501. A guide block 504 is fixedly connected to the side of the arc plate 502 close to the port of the latch chamber 501. A flat plate 505 is fixedly connected to the end of the arc plate 502 away from the port of the latch chamber 501.

A lever 507 adapted to be inserted through the notch 503 is fixedly connected to the side of the locking block 506. A telescopic column 508 is movably hinged to the end of the lever 507 through a pivot. The end of the telescopic column 508 away from the lever 507 is movably hinged to the latch chamber 501 through a pivot. A sealing strip 509 is fixedly nested on the outside of the port of the locking compartment 501; The structure of the second latch 9 is symmetrical to that of the first latch 5. The telescopic column 508 of the first latch 5 is electrically controlled.

[0031] The working principle of this invention is as follows: A second positioning component is installed on the marker post in the construction pit. The roller 707 in the power chamber 705 rotates under the drive of the rotator 708. Through the adapter of the rotator 708 to the plug-in rod slot 704, the power components on both sides of the moving rod 703 abut against it, so that the moving rod 703 slides up and down along the friction block 706, and the second half-ring mechanism 8 set against the marker post can slide along it. When the hull mechanism 1 approaches the construction pit, the mechanical arm 109 mounted on the hull mechanism 1 pushes the first positioning component held by it toward the marker post, so that the first half-ring mechanism 4 and the second half-ring mechanism 8 are connected. 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. Through the connection of the traction rope 405 on the first half-ring mechanism 4 with the pipe dropping mechanism 2, the pipe holding equipment 106 is used to correctly introduce the pipe dropping mechanism 2 into the construction pit, thereby improving the accuracy of rock throwing.

[0032] The outer ring of the second semi-ring mechanism 8 is equipped with second latches 9 at both ends, and the outer ring of the first semi-ring mechanism 4 is equipped with first latches 5 at both ends. When the first semi-ring mechanism 4 is connected to the second semi-ring mechanism 8 via the robotic arm 109, the guide block 504 of the first latch 5 is inserted into the second latch 9, and similarly, the second latch 9 is inserted into the first latch 5. The telescopic column 508 of the first latch 5 is extended by electric control, thereby pushing the lever 507 along the notch 503, so that the tangential surface of the locking block 506 and the arc plate 502 are flush, thus allowing the first latch 5 and the second latch 9 to be smoothly engaged. Then, by retracting the telescopic column 508, the lever 507 slides along the notch 503. At this time, the gap of the locking block 506 and the gap of the arc plate 502 are staggered, thereby completing the automatic locking and improving the convenience of docking.

[0033] A sealing strip 509 is embedded at the mating port of the first latch 5 and the second latch 9, and the telescopic column 508 of the first latch 5 is set inside the latch chamber 501 to prevent the telescopic column 508 from contacting the water source and improve its service life.

[0034] The traction mechanism 3 mounted on the bottom hopper 101 is connected to the second joint 403 of the first semi-ring mechanism 4 via an iron chain 303. The two traction mechanisms 3 are connected together with the marker to form a triangular stable structure. When there are waves on the sea surface, the hull mechanism 1 is connected to the marker of the construction pit through the connection of the first semi-ring mechanism 4 and the second semi-ring mechanism 8. Even if the hull mechanism 1 is driven by the waves, it can float around the marker, so that the stone is always placed around the construction pit, thus improving the stability of the stone placement.

[0035] The first semi-ring mechanism 4 is connected to the lower end of the outer pipe 201 by the traction rope 405. When the first semi-ring mechanism 4 slides down the marker into the construction pit under the drive of the second semi-ring mechanism 8, the pipe dropping mechanism 2 is inserted into the water under the drive of the pipe holding device 106. The traction rope 405 can follow the first semi-ring mechanism 4 to pull the pipe dropping mechanism 2 in the direction. When the position of the hull mechanism 1 fluctuates during the rock throwing process, the traction of the traction rope 405 can compensate for the attitude deviation of the hull mechanism 1 and improve the positioning accuracy of rock throwing.

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

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

The rotator (708) is adapted to the insertion rod slot (704), so that the power components on both sides of the moving rod (703) abut against it, thereby causing the moving rod (703) to slide up and down along the friction block (706). This allows the second semi-ring mechanism (8) that fits the marker post to slide along it. When the hull mechanism (1) approaches the construction pit, the hull mechanism (1) moves along the marker post. The robotic arm (109) mounted on the body mechanism (1) pushes the first positioning component it holds toward the marker post, so that the first half-ring mechanism (4) and the second half-ring mechanism (8) are connected. 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. Through the connection of the traction rope (405) on the first half-ring mechanism (4) with the pipe dropping mechanism (2), the pipe dropping mechanism (2) is correctly introduced into the construction pit in conjunction with the pipe holding equipment (106), thereby improving the accuracy of rock throwing.
