Abstract
Description
Technical Field
[0001] This utility model relates to the field of river dredging technology, and more specifically to a tracked amphibious dredging vessel. Background Technology
[0002] As river water flows, it continuously erodes the banks of the river, depositing sediment on the riverbed to form a silt layer. A small amount of silt is beneficial for the rooting and growth of underwater plants, but excessive silt accumulation can cause the riverbed to rise and even affect the normal passage of ships. Therefore, to restore the normal function of the river, it is necessary to regularly dredge and clean the river.
[0003] In the existing technology, dredging devices mainly operate by placing the hull on the water surface. However, the hull may encounter riverbanks or other ground conditions during the dredging process. Existing dredging devices are difficult to operate on riverbanks and other ground conditions, which can easily lead to the dredging device getting stuck and thus result in low dredging efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a tracked amphibious dredging vessel to solve the problem mentioned in the background art that the hull encounters riverbanks and other ground conditions during the dredging process, and the existing dredging devices are difficult to drive on riverbanks and other ground conditions, which easily leads to the dredging devices getting stuck, resulting in low dredging efficiency of the dredging vessel.
[0005] To achieve the above objectives, this utility model provides a tracked amphibious dredging vessel, comprising a hull, a hydraulic mechanical arm mounted on one side of the hull, a mounting frame fixedly mounted on the end of the hydraulic mechanical arm away from the hull, a shovel dredging device mounted at the bottom of the mounting frame, tracked main bodies for moving on land mounted on both sides of the hull, a propeller for moving on the water surface mounted on the side of the hull away from the hydraulic mechanical arm, and the propeller is configured as a twin-propeller structure, and floats mounted on both sidewalls of the hull, with two floats symmetrically arranged on both sides of the hull.
[0006] By adopting the above scheme, the dredging vessel moves and turns on the ground such as riverbanks by relying on the tracked main body, and in the water, the two floats make the dredging vessel float in the river channel and move by relying on the propeller, making the dredging vessel suitable for amphibious use, thereby improving the practical effect of the dredging vessel.
[0007] As a further improvement to this technical solution, the mounting frame is detachably connected to the hydraulic robotic arm, and the dredging equipment is detachably installed to the hydraulic robotic arm via the mounting frame.
[0008] By adopting the above solution, the dredging equipment can be replaced with other equipment to meet the work requirements. For example, it can be replaced with a rake for clearing weeds and dead branches, a bucket for digging, a grab bucket for dry bulk cargo, a pile driver for piling, a hydraulic mechanical gripper for grabbing, etc., which improves the adaptability of the equipment.
[0009] As a further improvement to this technical solution, the cutterhead dredging equipment includes a cutterhead body and a pump. The cutterhead body is fixedly installed at the bottom of the mounting frame, and the pump is fixedly installed at the side end of the cutterhead body.
[0010] By adopting the above scheme, the cutter body can break up silt and other debris at the bottom of the river, thereby facilitating the pump to suck up the silt.
[0011] As a further improvement to this technical solution, an engine set is provided at the upper end of the hull, and an operating room is provided at the upper end of the hull on one side of the engine set.
[0012] By adopting the above solution, it is convenient to provide power and operational control for the dredging vessel.
[0013] As a further improvement to this technical solution, both the reamer body and the top of the pump are equipped with hydraulic motors, the bottom of the pump is equipped with a suction port, and the top of the pump is equipped with a discharge port.
[0014] By adopting the above scheme, both the reamer body and the pump are powered by hydraulic motors.
[0015] As a further improvement to this technical solution, two fixed plates are fixedly installed on the side of the hull away from the hydraulic robotic arm. Hydraulic rods are fixedly installed on both fixed plates, and the output ends of the two hydraulic rods pass through the fixed plates and are fixedly fitted with insert rods.
[0016] By adopting the above scheme, the hydraulic rod is activated, which drives the insertion rod to move downward, so that the insertion rod is inserted into the soil. This allows the dredging vessel to hover on the water surface, making it convenient for the dredging vessel to carry out targeted dredging of the river.
[0017] As a further improvement to this technical solution, two supports are hinged to the side of the hull near the hydraulic robotic arm, and floats are provided on the side of the two supports away from the hull. A hydraulic cylinder is provided at the side end of the hull and hinged to the supports.
[0018] By adopting the above scheme, the buoy provides resistance to the movement of the dredging vessel, further ensuring the stability of the dredging vessel in fixed-point dredging.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This tracked amphibious dredging vessel is equipped with a cutterhead dredging device. The cutterhead body breaks up silt and other debris on the bottom of the river, making it easier for the pump to suck up the silt and preventing the debris in the silt from clogging the pipeline. The cutterhead dredging device can be detached and installed via a mounting frame and a hydraulic mechanical arm. The cutterhead dredging device can be replaced with other equipment to meet the work requirements, thus improving the adaptability of the equipment.
[0021] 2. This tracked amphibious dredging vessel, equipped with tracks and a propeller, moves and turns on land such as riverbanks using the tracked main body. In water, two floats allow the dredging vessel to float in the river channel, and it moves using the propeller. This makes the dredging vessel suitable for amphibious use, thereby improving its practical effectiveness. Attached Figure Description

[0029] Please see Figures 1-3 As shown, this utility model provides a tracked amphibious dredging vessel, including a hull 1. A hydraulic mechanical arm 2 is installed on one side of the hull 1. A mounting frame 3 is fixedly installed at the end of the hydraulic mechanical arm 2 away from the hull 1. A dredging device 4 is installed at the bottom of the mounting frame 3. The dredging device 4 includes a dredging body 5 and a pump 6. The dredging body 5 is fixedly installed at the bottom of the mounting frame 3, and the pump 6 is fixedly installed at the side end of the dredging body 5. The hydraulic mechanical arm 2 drives the dredging device 4 downward into the bottom of the river channel. The dredging body 5 breaks up the silt and other debris at the bottom of the river channel, which facilitates the pump 6 to suck up the silt and prevents the debris in the silt from clogging the pipeline. A hydraulic motor 7 is installed at the top of both the dredging body 5 and the pump 6. Both the reamer body 5 and the pump 6 are powered by a hydraulic motor 7. The pump 6 has a suction port 8 at its bottom and a discharge port 9 at its top. By connecting the discharge port 9 to an external pipeline, silt and other debris are sucked into the pump 6 through the suction port 8 and discharged into the external pipeline through the discharge port 9. The mounting frame 3 is detachably connected to the hydraulic mechanical arm 2. The reamer dredging equipment 4 is detachably installed and mounted on the hydraulic mechanical arm 2 via the mounting frame 3. The reamer dredging equipment 4 can be replaced with other equipment to meet work requirements, such as a rake for clearing weeds and dead branches, a digging bucket for excavation, a grab bucket for dry bulk goods, a pile driver for piling, or a hydraulic mechanical gripper for grabbing, thus improving the adaptability of the equipment.
[0030] Please see Figures 1-2As shown, the hull 1 has tracked bodies 11 on both sides for movement on land. A propeller 12 for movement on water is located on the side of the hull 1 away from the hydraulic manipulator 2, and the propeller 12 is a twin-propeller structure. An engine unit 15 is located at the upper end of the hull 1, and an operator's cab 16 is located on the side of the engine unit 15 at the upper end of the hull 1. Floats 17 are symmetrically arranged on both sides of the hull 1. When the dredging vessel is on land such as riverbanks, it moves and turns using the tracked bodies 11. When in water, the two floats 17 allow the dredging vessel to float in the river channel and move using the propeller 12, making the dredging vessel suitable for amphibious use. Two fixed plates 10 are fixedly installed on the side of the hull 1 away from the hydraulic manipulator 2, and hydraulic... The output ends of the two hydraulic rods 13 pass through the fixed plate 10 and are fixedly equipped with insertion rods 14. When the hydraulic rods 13 are activated, the gears are driven to rotate, which in turn drives the chain inside the positioning pile to rotate, thereby causing the insertion rods 14 to be inserted downward into the silt. This allows the dredging vessel to hover on the water surface, facilitating the dredging vessel to perform targeted dredging of the river. Two supports 18 are hinged on the side of the hull 1 near the hydraulic mechanical arm 2. Floats 19 are installed on the side of the two supports 18 away from the hull 1. A hydraulic cylinder 20 is installed on the side of the hull 1 and hinged to the supports 18. When the hydraulic cylinder 20 is activated, it drives the supports 18 to rotate downward. The supports 18 drive the floats 19 to contact the water surface downward, providing resistance for the movement of the dredging vessel and further ensuring the stability of the dredging vessel in targeted dredging.
[0031] The specific working principle of this utility model is as follows: the hydraulic mechanical arm 2 drives the dredging equipment 4 downward into the bottom of the river channel. The dredging body 5 crushes the silt and other debris at the bottom of the river channel, which facilitates the pump 6 to suck up the silt and avoids the debris in the silt from clogging the pipeline. By connecting the discharge port 9 to the external pipeline, the silt and other debris are sucked into the pump 6 through the suction port 8 and then discharged into the external pipeline through the discharge port 9. When the dredging vessel is on the riverbank or other ground, it moves and turns by means of the tracked body 11. When in the water, the two floats 17 make the dredging vessel float in the river channel and move by means of the propeller 12, so that the dredging vessel is suitable for amphibious use.
