Description

Technical Field

[0001] The invention relates to the technical field of ship ripraps, and in particular to a simple and easy-to-use riprap. Background Art

[0002] With the acceleration of global economic integration and the frequent international trade, the construction and development of ports as important hubs connecting sea and land are particularly important. In order to adapt to the growing cargo throughput, ports around the world have stepped up their construction efforts, widened and deepened waterways, expanded docks, and improved supporting logistics facilities, which have put forward higher requirements for navigation operations, including the accuracy of navigation setting, timeliness of maintenance, and advanced technology, to ensure that ships can enter and leave the port safely and efficiently.

[0003] A navigation mark is a navigation aid that uses specific signs, lights, sound or radio signals to help ships determine their position and direction, avoid danger, and sail safely along the waterway or predetermined route. Modern navigation aid systems include lighthouses, buoys, and beacons, which use visual, auditory and electronic signals to provide navigation assistance to ships. These aids not only indicate the direction of the waterway, but also mark dangerous areas to ensure safe and efficient navigation of ships.

[0004] The riprap on a beacon ship is a device specially designed to drop sunken stones or other heavy objects during navigation operations. The riprap equipment used on beacon ships mainly includes flap ripraps and telescopic ripraps; sunken stones are usually hoisted by cranes, but in this process, multiple people are required to assist the crane in pushing and pulling the sunken stones so that the sunken stones fall accurately on the middle line of the riprap tray to maintain the balance of the riprap and facilitate subsequent riprap. This process is not only labor-intensive, but also because the personnel are under the sunken stones, anchor chains, and hooks; and because of the slight shaking of the ship and the uneven strength of the personnel, it is difficult to ensure that the middle line of the sunken stone coincides with the middle line of the tray, causing the sunken stone to easily tip over during throwing and hit the tray on one side. In the long run, the left and right shaft keys of the riprap will malfunction; Moreover, in the existing riprap design, the flap riprap needs to extend the sinker overboard, and the two flaps sometimes cannot be opened synchronously, causing the sinker to be stuck on the riprap and unable to enter the water smoothly; the telescopic riprap also needs to extend the sinker overboard, and the front and rear shifting tooth assembly is prone to malfunction due to the gravity of the sinker, making it difficult for the sinker to extend outward, affecting the efficiency of the riprap operation, and further affecting the efficiency and safety of the riprap operation; and neither the flap riprap nor the telescopic riprap has a device to prevent accidental stone sliding caused by the tilting of the ship, which may cause the sinker to accidentally slide when the ship is tilted or unstable, causing a safety accident. Summary of the invention

[0005] The purpose of the present invention is to provide a simple and easy-to-use riprap device which can improve the efficiency of riprap operation, reduce potential safety hazards, save time and effort, so as to solve the technical problem that when riprap is performed in the prior art, the sinker needs to be centered, otherwise the device may be damaged, the riprap efficiency may be reduced, and safety may be easily generated.

[0006] In order to solve the above technical problems, the solution adopted by the present invention is as follows: A simple and easy-to-use riprap, used for throwing sinking stones, comprises a sinking stone bearing seat, a sliding frame, a supporting oil cylinder, a rotating device and a power device; the sinking stone bearing seat is fixedly installed on the ship deck, one end of the sinking stone bearing seat is arranged with a rotating device, and the other end is arranged with a power device; the sliding frame is located directly above the sinking stone bearing seat, and one end is rotatably connected to one end of the sinking stone bearing seat through the rotating device; the sliding frame comprises a blocking device, a roller, mutually matching bearings and a bearing seat; the roller is provided with a plurality of rollers, and the sinking stone is supported by the sinking stone bearing seat and the roller; the bearing is installed at both ends of the roller; the bearing seat is fixedly installed on the sliding frame, and is used to support the bearing, so that the roller can rotate through the bearing; the roller is connected to the sliding frame through the bearing and the bearing seat; The rotating device includes a pin shaft and a pin shaft support; a pin shaft support is fixedly installed on both sides of one end of the sinker bearing seat; both ends of the pin shaft are connected to the pin shaft support; the sliding frame is rotatably connected to one end of the sinker bearing seat through the pin shaft and the pin shaft support; the blocking device is located on the inner side of the pin shaft; The blocking device comprises a mounting seat, a safety cross block, a safety cross block pin, a connecting rod and a connecting plate; the mounting seat is fixedly mounted on both sides of one end of the sinker load-bearing seat; both ends of the safety cross block pin are rotatably connected to the mounting seat; the safety cross block is provided with a plurality of safety cross blocks, evenly distributed on the safety cross block pin; both ends of the connecting plate are welded to the sliding frame; one end of the connecting rod is rotatably connected to the safety cross block, and the other end is rotatably connected to the bottom of the connecting plate; the number of the connecting rods matches the number of the safety cross blocks; the sliding frame starts the supporting cylinder through the power device to drive the sliding frame to lift up, thereby pulling the connecting rod through the connecting plate to drive the safety cross block and the safety cross block pin to rotate relative to the mounting seat; One end of the supporting oil cylinder is rotatably connected to the sinker load-bearing seat, and the other end is rotatably connected to the other end of the sliding frame; the power device is placed in the engine room just below the ship deck, and is connected to the supporting oil cylinder; when the supporting oil cylinder is extended, one end of the sliding frame rotates relative to the sinker load-bearing seat through the pin shaft and the pin shaft support, lifting the other end of the sliding frame, so that the roller of the sliding frame is separated from the sinker load-bearing seat.

[0007] Furthermore, the sinker bearing seat is provided with a U-shaped groove and a water leakage hole; the U-shaped groove is opened at the upper end of the sinker bearing seat and matches the drum. When the sliding frame is lowered, the drum can be hidden in the U-shaped groove; the water leakage hole is opened at the lower end of the sinker bearing seat and is located directly below the U-shaped groove. The size of the U-shaped groove matches the drum. When the sliding frame is lowered, the drum is stored in the U-shaped groove. The sinker is supported by the sinker bearing seat protruding on both sides of the U-shaped groove to avoid the sinker accidentally sliding off due to the tilting of the ship when the sinker is not being thrown. The water leakage hole is used to discharge the water in the U-shaped groove to avoid the sinker bearing seat being soaked in water for a long time and causing it to rust.

[0008] Furthermore, the power device includes a power pump station and a manual manpower pump; the power pump station is installed in the engine room, and the manual manpower pump is installed on one side of the power pump station, and is used to manually increase the pressure when the power pump station is damaged, so that the stone throwing work can operate normally; the power pump station and the manual manpower pump are connected to the support cylinder through a seamless steel pipe or a high-pressure hose. The power pump station transmits power to the support cylinder through a seamless steel pipe or a high-pressure hose, so that the support cylinder extends and supports the sliding frame. Due to the inclination of the sliding frame, the sinking stone on the sliding frame slides from a high place to a low place through the roller on the sliding frame, so that the sinking stone slides into the water, achieving a stone throwing effect. When the power pump station is damaged or the ship loses power, the sliding frame can be raised by the manual pump, and the sinking stone placed on the sliding frame can be thrown into the water for emergency stone throwing, or the sliding frame can be lowered.

[0009] Furthermore, the height of the safety cross block is higher than the roller, and can swing along with the sliding frame through the connecting plate and the connecting rod. The safety cross block can effectively prevent the phenomenon of the sunken stone falling into the water due to the tilt of the ship during the driving process. When the sliding frame rotates and rises, the safety cross block is pulled down by the connecting plate and the connecting rod, so that the roller of the sliding frame is higher than the safety cross block, so that the sunken stone can slide off the roller without hindrance. The tail of the other end of the sliding frame is not provided with a roller. When the ship tilts toward the other end, the friction force can prevent the sunken stone from sliding off from the other side.

[0010] Furthermore, the supporting oil cylinders are provided with two, which are respectively installed on both sides of the sinking stone bearing seat. The supporting oil cylinders are one on each side, and the two oil cylinders work simultaneously, which can ensure that the sliding frame is balanced and raised or lowered at the same time. When the oil cylinders are retracted, the sliding frame is in a horizontal state, and when the oil cylinders are extended, the sliding frame rises and throws the sinking stone into the water.

[0011] Furthermore, the rotation angle of the sliding frame is 0-20°. The rotation angle of the sliding frame is 0-20°, which can effectively reduce the error or damage caused by excessive rotation while ensuring that the sinker can effectively slide off the drum through the inclined angle.

[0012] The working principle of the present invention is as follows: When throwing stones, the heavy stones are placed on the sliding frame by a crane without aligning them with the center line. After the heavy stones are placed, the power pump station is started by operating the button to extend the supporting cylinders on both sides of the sliding frame at the same time, thereby driving the sliding frame to rise, causing the sliding frame to rotate relative to the heavy stone bearing seat, and the drum is separated from the U-shaped groove on the heavy stone bearing seat. When the sliding frame rotates, the safety cross block is pulled by the connecting rod at the bottom of the connecting plate, which causes the safety cross block pin to rotate relative to the mounting seat, thereby lowering the safety cross block, making it easier for the heavy stone to be lifted from the sliding frame. The drum slides into the water. After the sunk stone slides into the water, the sliding frame rotates to return to its original state, the safety cross block is also reset, and the drum is placed in the U-shaped groove to store the drum. At the same time, the top of the U-shaped groove of the sunk stone load-bearing seat is in direct contact with the sunk stone to support the sunk stone. The safety cross block on the inner side of the pin shaft can prevent the sunk stone from sliding into the water when the ship tilts. When the power pump station is damaged or the ship loses power, the manual manpower pump can be manually shaken to raise the sliding frame for emergency stone throwing or the sliding frame can be lowered for storage.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides power through a power device and a supporting oil cylinder installed under the deck of the ship to rotate and rise the sliding frame, and the sinker is slid from the sliding frame into the water through the roller of the sliding frame. The overall operation is simple, and there is no need to place the sinker on the center line. The safety cross block of the blocking device can prevent the sinker from accidentally sliding down due to the tilt of the ship, thereby ensuring the safety of the operators and reducing the risk of equipment failure.

[0014] 2. The present invention ensures that the sunken stones are stably stored on the riprap device when no riprap operation is being carried out through the design of the U-shaped groove and the leakage hole, thereby preventing the sunken stones from shifting or sliding due to the shaking of the ship, and ensuring the accuracy of the sunken stone placement.

[0015] 3. The present invention reduces the error or damage caused by excessive rotation by limiting the rotation angle of the sliding frame, thereby extending the service life of the equipment. At the same time, the setting of the manual manpower pump provides a backup plan when the power pump station is damaged, ensuring the continuity of the riprap operation.

[0020] The following is a further detailed description of a simple and easy-to-use riprap device of the present invention in conjunction with the accompanying drawings: Embodiment 1: A simple and easy-to-use riprap, used for throwing a sinking stone 12, comprises a sinking stone bearing seat 1, a sliding frame 2, a supporting oil cylinder 3, a rotating device and a power device; the sinking stone bearing seat 1 is fixedly installed on the deck of a ship, a rotating device is arranged at one end of the sinking stone bearing seat 1, and a power device is arranged at the other end; the sliding frame 2 is located directly above the sinking stone bearing seat 1, and one end is rotatably connected to one end of the sinking stone bearing seat 1 through the rotating device; The sliding frame 2 includes a blocking device 6, a roller 9, a bearing 10 and a bearing seat 11 that cooperate with each other; the roller 9 is provided with a plurality of bearings 10; the bearings 10 are installed at both ends of the roller 9; the bearing seat 11 is fixedly installed on the sliding frame 2; the roller 9 is connected to the sliding frame 2 through the bearing 10 and the bearing seat 11; The rotating device includes a pin shaft 4 and a pin shaft support 5.

[0021] The working principle of this embodiment is as follows: When throwing stones, the heavy stone 12 is placed on the sliding frame 2 by a crane, and it is not necessary to align it with the center line. After placing the heavy stone 12, the power device is started by operating the button to extend the supporting cylinder 3 at the bottom of the sliding frame 2, thereby driving the sliding frame 2 to rise, so that the sliding frame 2 rotates 20° relative to the heavy stone bearing seat 1, and the roller 9 is separated from the heavy stone bearing seat 1. When the sliding frame 2 rotates, the safety cross block 62 is pulled by the connecting rod 64 of the connecting plate 65, and the safety cross block pin 63 rotates relative to the mounting seat 61. Then the safety cross block 62 is lowered, so that the drum 9 is higher than the safety cross block 62, which facilitates the sinker 12 to slide from the drum 9 into the water. After the sinker slides into the water, the supporting cylinder 3 contracts to rotate the sliding frame 2 to restore it to its original state. At the same time, the top of the sinker load-bearing seat 1 is in direct contact with the sinker 12 to support the sinker 12. The reset of the sliding frame 2 drives the reset of the safety cross block 62 to prevent the sinker 12 from sliding into the water when the ship tilts, thereby ensuring the safety of the operators and reducing the risk of equipment failure.

[0022] Embodiment 2: The difference from Embodiment 1 lies in that the sinker load-bearing seat 1 is provided with a U-shaped groove 7 and a leakage hole 8; the U-shaped groove 7 is arranged at the upper end of the sinker load-bearing seat 1 and matches the roller 9; the leakage hole 8 is arranged at the lower end of the sinker load-bearing seat 1 and is located directly below the U-shaped groove 7; the power device comprises a power pump station and a manual manpower pump; the power pump station is installed in the cabin, and the manual manpower pump is installed on one side of the power pump station; the power pump station and the manual manpower pump are respectively connected to the supporting cylinder 3 through pipelines; the height of the safety cross block 6 is higher than the roller 9, and can swing with the sliding frame 2 through the connecting plate 65 and the connecting rod 64; the supporting cylinder 3 is provided with two, which are respectively installed on both sides of the sinker load-bearing seat 1; the rotation angle of the sliding frame 2 is 20°. The power pump station transmits power to the supporting cylinder 3 through the seamless steel pipe, so that the supporting cylinders 3 on both sides of the sinking stone bearing seat 1 extend at the same time, supporting the sliding frame 2, so that the sliding frame 2 rotates at an angle of 20° relative to the sinking stone bearing seat 1. Due to the inclination of the sinking stone 12 on the sliding frame 2, the roller 9 on the sliding frame 2 slides from a high place to a low place, thereby sliding the sinking stone 12 into the water, playing a role of throwing stones. The size of the U-shaped groove 7 matches the roller 9. After throwing stones, the supporting cylinder 3 contracts to put down the sliding frame 2, and the roller 9 is lowered. The sinker 12 is housed in the U-shaped groove 7, and is supported by the sinker bearing seats 1 protruding on both sides of the U-shaped groove 7. When no stone throwing is performed on the sinker 12, the safety cross block 8 can effectively prevent the sinker 12 from falling into the water due to the tilting of the ship during navigation. The leakage hole 7 is used to discharge the water in the U-shaped groove 6 to prevent the sinker bearing seat 1 from being soaked in water for a long time and causing it to rust. When the power pump station is damaged, the sliding frame can be raised by a manual pump, and the sinker placed on the sliding frame can be thrown into the water for emergency stone throwing.

[0023] The working principle of this embodiment is the same as that of Embodiment 1.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
