Description

Technical Field

[0001] This utility model relates to the field of dredging engineering technology, and in particular to a shallow-sweeping plate for a trailing suction hopper. Background Technology

[0002] Currently, although trailing suction hopper dredgers use the "S"-shaped routing method to minimize the existence of shallow spots during the construction of the quality layer in dredging projects, the flexible connection of the dredger head during construction makes it difficult to accurately control the underwater progress, inevitably resulting in shallow spots and shallow embankments, which require shallowing operations.

[0003] When faced with loose soil and a wide area of ​​shallow spots, the coverage area of ​​the rake head is limited. The deeper it goes, the more difficult it becomes to reach shallower areas, and the overall construction efficiency is very slow, which brings many difficulties and troubles to the dredging process and affects the effective construction progress. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a shallow-sweeping flat plate for the rake head of a shovel dredger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shallow-sweeping plate for a shovel suction dredger includes a mounting base fixed to the shovel head. A fixing plate is fixed to the side of the mounting base. A swing plate is rotatably connected to the end of the fixing plate away from the mounting base via a pin. An extension plate is slidably connected inside the swing plate. A first elastic telescopic rod is provided between the swing plate and the extension plate. A positioning component for positioning the extension plate is provided on the swing plate. A winding component for pulling the swing plate is provided on the mounting base. A limiting component for restricting the movement of the swing plate is provided on the fixing plate. The limiting component is connected to the winding component.

[0007] Preferably, the winding assembly includes a waterproof cavity formed in the mounting base, a drive motor fixed in the waterproof cavity, a winding rod connected to the output shaft of the drive motor and rotatably connected in the waterproof cavity, a first drum fixed on the winding rod, and a first pull rope wound around the first drum. The end of the first pull rope away from the first drum passes through the mounting base and the swing plate in sequence and is fixedly connected to the end of the extension plate near the fixed plate.

[0008] Preferably, the limiting assembly includes a housing fixed to a fixed plate, a limiting plate slidably connected inside the housing, and an elastic element disposed between the inner wall of the housing and the limiting plate. A second drum is provided on the winding rod, and a second pull rope is wound and connected to the second drum. The end of the second pull rope away from the second drum passes through the mounting base and the housing in sequence and is connected to the limiting plate.

[0009] Preferably, both the first and second pull ropes are made of steel strand connecting cables.

[0010] Preferably, the positioning assembly includes a support plate fixed to the swing plate, a second elastic telescopic rod fixed to the support plate, and a positioning plate disposed at the end of the second elastic telescopic rod and slidably connected to the swing plate and the extension plate. The extension plate has a positioning groove for insertion into the positioning plate, and a first inclined surface is formed on one side of the end of the positioning plate.

[0011] Preferably, the positioning plate has a recessed hole, and the inner wall of the recessed hole has a second inclined surface that moves against the limiting plate.

[0012] Preferably, a reinforcing rib and a steel bar connector are provided between the mounting base and the fixing plate.

[0013] Compared with the prior art, the present invention provides a shallow-sweeping flat plate for the rake head of a trailing suction hopper dredger, which has the following beneficial effects:

[0014] 1. The shallow-sweeping plate of the shovel head of this shovel suction dredger forms a shallow-sweeping plate by setting a fixed plate and a swing plate on the shovel head. Compared with the traditional shallow-sweeping method, it not only has the characteristics of good effect and high precision, but also effectively increases the shallow-sweeping coverage area of ​​the shovel head, thus improving the shallow-sweeping effect and efficiency.

[0015] 2. The shallow-sweeping plate of the dredging head of the dredging vessel, by sliding an extension plate on the swing plate, further increases the shallow-sweeping area, effectively solving the problems of thin dredging layer, large area, and poor shallow-point removal effect in dredging projects.

[0016] 3. The shallow-sweeping plate of the shovel suction dredger is connected to the fixed plate by rotating the swing plate. When the swing plate is not in use, it can be folded and stored by the winding assembly, which makes it easier to reduce the space occupied by the shallow-sweeping plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] Example: Refer to Figure 1 , Figure 2 and Figure 3A shallow-sweeping plate for a shovel suction dredger includes a mounting base 2 fixed to the shovel head, a fixing plate 3 fixed to the side of the mounting base 2, a swing plate 4 rotatably connected to the end of the fixing plate 3 away from the mounting base 2 via a pin 1, an extension plate 5 slidably connected inside the swing plate 4, a first elastic telescopic rod 501 provided between the swing plate 4 and the extension plate 5, a positioning component for positioning the extension plate 5 provided on the swing plate 4, a winding component for pulling the swing plate 4 provided on the mounting base 2, and a limiting component for restricting the movement of the swing plate 4 provided on the fixing plate 3, the limiting component being connected to the winding component.

[0027] Specifically, during shallow water clearing, the winding assembly no longer pulls the swing plate 4, while the limiting assembly drives the swing plate 4, placing it on the same plane as the fixed plate 3. The fixed plate 3 and the swing plate 4 on the rake head form a shallow water clearing plate. Compared to traditional shallow water clearing methods, this not only offers better results and higher precision but also effectively increases the rake head's shallow water clearing coverage area, improving the clearing effect and efficiency. Furthermore, the swing plate 4 and the fixed plate 3 are rotatably connected, and when not in use, the swing plate 4 can be folded and stored using the winding assembly, reducing the space occupied by the shallow water clearing plate. The specific operating steps are as follows: Based on different shallow water point types and the wiring method used in the initial construction, a combination of "fixed-point clearing" and "joint clearing" of individual connected points is employed, with repeated clearing operations. For isolated shallow water points, multiple line-up and reciprocating excavation methods are used. Since each shallow water point is different, during shallow water clearing using the trailing suction hopper, the number of times the shallow water point needs to be cleared depends on the position of the rake head and the shallow water clearing plate each time, the shallow water thickness, and the height of the shallow water point, in order to meet the acceptance standards.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As a preferred technical solution of the present invention, the winding assembly further includes a waterproof cavity 6 opened in the mounting base 2, a drive motor 601 fixed in the waterproof cavity 6, a winding rod 602 connected to the output shaft of the drive motor 601 and rotatably connected in the waterproof cavity 6, a first drum 603 fixed on the winding rod 602, and a first pull rope 6031 wound and connected to the first drum 603. The end of the first pull rope 6031 away from the first drum 603 passes through the mounting base 2 and the swing plate 4 in sequence and is fixedly connected to the end of the extension plate 5 near the fixed plate 3.

[0029] Furthermore, the limiting assembly includes a housing 7 fixed on the fixed plate 3, a limiting plate 701 slidably connected inside the housing 7, and an elastic element 702 disposed between the inner wall of the housing 7 and the limiting plate 701. A second drum 604 is provided on the winding rod 602, and a second pull rope 6041 is wound and connected to the second drum 604. The end of the second pull rope 6041 away from the second drum 604 passes through the mounting base 2 and the housing 7 in sequence and is connected to the limiting plate 701.

[0030] Furthermore, both the first pull rope 6031 and the second pull rope 6041 are made of steel strand connecting cable.

[0031] Furthermore, the positioning assembly includes a support plate 8 fixed on the swing plate 4, a second elastic telescopic rod 801 fixed on the support plate 8, and a positioning plate 802 disposed at the end of the second elastic telescopic rod 801 and slidably connected to the swing plate 4 and the extension plate 5. The extension plate 5 is provided with a positioning groove 502 that is inserted into the positioning plate 802, and a first inclined surface is provided on one side of the end of the positioning plate 802.

[0032] Furthermore, the positioning plate 802 has a recessed hole 8021, and the inner wall of the recessed hole 8021 has a second inclined surface that moves against the limiting plate 701.

[0033] Specifically, when the shallow sweeping plate is in use, the drive motor 601 is controlled to run. The output shaft of the drive motor 601 drives the take-up rod 602 to rotate within the waterproof cavity 6. When the take-up rod 602 rotates, the first drum 603 releases the first pull rope 6031, and the second drum 604 releases the second pull rope 6041. The first pull rope 6031 no longer pulls the swing plate 4, and the second pull rope 6041 no longer pulls the limiting plate 701. The limiting plate 701 is then compressed by the elastic element 70. 2. Pushing the outer casing 7 out and applying a pushing force to the swing plate 4, the swing plate 4 rotates around the pin 1, causing the swing plate 4 to move to be in line with the fixed plate 3. When the limiting plate 701 moves, it is inserted into the concave hole 8021. The end of the limiting plate 701 presses against the second inclined surface, causing the positioning plate 802 to move under force and press against the second elastic telescopic rod 801. The end of the positioning plate 802 moves out of the positioning groove 502, and the extension plate 5 is no longer pulled by the first pull rope 6031 and the positioning plate 802. Due to the limitations, the extension plate 5 is reset and moved out of the swing plate 4 under the push of the compressed first elastic telescopic rod 501, further increasing the dredging area and effectively solving the problems of thin dredging layer, large area and poor shallow point removal effect in dredging projects; when the dredging plate is not in use, the winding assembly winds the first pull rope 6031 through the first drum 603 and the second pull rope 6041 through the second drum 604. The second pull rope 6041 pulls the limiting plate 701 back into the outer shell 7. When the first pull rope 6031 winds, it pulls the extension plate 5 to retract into the swing plate 4, so that when the extension plate 5 moves back, it squeezes the first inclined surface at the end of the positioning plate 802. The positioning plate 802 avoids the movement of the extension plate 5 until the positioning groove 502 is aligned with the positioning plate 802. The positioning plate 802 is re-inserted into the positioning groove 502 under the push of the second elastic telescopic rod 801. Then the first pull rope 6031 transmits the force to the swing plate 4, so that the swing plate 4 resets and flips for storage, reducing its storage space.

[0034] Reference Figure 1 and Figure 3 As a preferred technical solution of the present invention, further, a reinforcing rib 9 and a steel bar connector 10 are provided between the mounting base 2 and the fixing plate 3; specifically, the provision of the reinforcing rib 9 and the steel bar connector 10 improves the stability between the mounting base 2 and the fixing plate 3, thereby improving the stability of the shallow flat plate structure installation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
