Description

Technical Field

[0001] The invention relates to the technical field of dredging engineering, and in particular to an adjustable drag head device and a use method thereof. Background Art

[0002] As an important equipment in dredging projects, the main function of the trailing suction hopper dredger is to cut and dig the underwater soil through the drag head, and suck the excavated soil into the ship for storage or directly transport it to a designated location, so as to achieve the purpose of widening the channel, deepening the harbor, maintaining the depth of the water area, etc. During the operation, the trailing suction hopper dredger controls the drag head to be lowered to a suitable depth, and relies on the movement of the ship to drive the drag head to move for cutting operations.

A rake tooth structure 400 is welded on the support cover 200. When the driving oil cylinder 500 is extended or retracted, the support cover 200 drives the rake tooth structure 400 to change the inclination angle synchronously, thereby adjusting the cutting posture.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] As an important equipment in dredging projects, the main function of the trailing suction hopper dredger is to cut and dig the underwater soil through the drag head, and suck the excavated soil into the ship for storage or directly transport it to a designated location, so as to achieve the purpose of widening the channel, deepening the harbor, maintaining the depth of the water area, etc. During the operation, the trailing suction hopper dredger controls the drag head to be lowered to a suitable depth, and relies on the movement of the ship to drive the drag head to move for cutting operations.

[0042] The structure of the rake head in the prior art (such as Figure 1 The cutting tool 100 is mainly composed of a fixed body 100 and a support cover 200, which are hinged through a rotating shaft hole 300 and driven by a single driving oil cylinder 500 to rotate the support cover 200 as a whole. A rake tooth structure 400 is welded on the support cover 200. When the driving oil cylinder 500 is extended or retracted, the support cover 200 drives the rake tooth structure 400 to change the inclination angle synchronously, thereby adjusting the cutting posture.

[0043] However, since the rake tooth structure 400 is rigidly fixedly connected to the support cover 200, the cutting posture of the rake tooth structure 400 relative to the ground changes synchronously with the support cover 200, and independent adjustment of the cutting depth and the cutting angle cannot be achieved. As a result, the space for adjusting the support cover 200 and the rake tooth structure 400 fixed thereto according to the actual construction environment is very limited, and therefore the construction state with optimal efficiency cannot be achieved.

[0044] Therefore, there is an urgent need for an adjustable rake head device and a use method to solve the above technical problems.

[0045] Embodiment 1

[0046] The embodiment of the present invention provides an adjustable drag head device, which can adjust the cutting depth and cutting angle of the drag head to achieve an optimal construction state.

[0047] See also Figure 2The adjustable rake head device provided by the embodiment of the present invention includes a main body 1, a movable cover 2, a cutting assembly 3, a first driving member, a second driving member and a control assembly. The movable cover 2 is rotatably connected to the main body 1; the cutting assembly 3 includes a support beam 31 and cutting rake teeth 32, and a plurality of cutting rake teeth 32 are arranged on the support beam 31 along its own extension direction, and the support beam 31 is rotatably connected to the movable cover 2; the first driving member is used to drive the movable cover 2 to rotate to adjust the cutting depth of the cutting rake teeth 32; the second driving member is used to drive the support beam 31 to rotate to adjust the cutting angle of the cutting rake teeth 32; the control assembly includes an input module, a calculation module and a control module, the input module is used to obtain soil condition parameters, the calculation module can generate a target cutting depth and a target cutting angle based on the soil condition parameters, and the control module is used to control the operation of the first driving member and the second driving member.

[0048] The adjustable rake head device proposed in the present invention, when in use, first obtains soil condition parameters through an input module according to the properties of the target dredged soil, and then generates a target cutting depth and a target cutting angle based on the obtained soil condition parameters through a calculation module. Thereafter, the control module controls the first driving member to drive the movable cover 2 to rotate, so as to change the relative inclination angle between the movable cover 2 as a whole and the bottom surface, and directly controls the vertical cutting amount of the cutting rake teeth 32, thereby realizing precise adjustment of the cutting depth of the cutting rake teeth 32 until the cutting depth reaches the target cutting depth; and controls the second driving member to drive the support beam 31 to rotate, so that the multiple cutting rake teeth 32 arranged along the extension direction of the support beam 31 can synchronously change the contact angle with the surface to be cut, and then independently adjust the attack angle of the cutting rake teeth 32 until the cutting angle of the cutting rake teeth 32 reaches the target cutting angle, thereby achieving the best construction state.

[0049] The adjustable rake head device can accurately calculate and adjust the cutting depth and cutting angle of the cutting rake teeth 32 based on soil density, particle size and mud concentration through the coordinated cooperation of various components through intelligent dynamic coupling, thereby ensuring the optimal cutting effect under different soil conditions such as clay, sand or mixed soil, without relying on the operator's experience, improving the adaptability of the rake head to different soil conditions, and ensuring that the rake head is always in an efficient construction state, reducing the inefficiency caused by improper parameter adjustment, and effectively improving the overall efficiency and quality of dredging operations.

[0050] The specific structure of the adjustable rake head device is described below.

[0051] The main body 1 serves as the basic bearing structure of the entire adjustable rake head device, providing an installation and support platform for other components. The main body 1 is made of high-strength metal materials and has sufficient strength and rigidity to withstand various forces generated during dredging operations, including cutting force, water flow impact force, and the gravity of the equipment itself. Its shape and structural design are determined according to the actual application scenario and the coordination requirements with other components. The main body 1 is provided with an installation interface and a positioning structure to accurately connect and assemble with the movable cover 2, the first drive member and other components to ensure that the various components can work together and stably during operation.

[0052] The two ends of the support beam 31 are respectively fixedly connected with support end plates 34, and the support end plates 34 and the movable cover 2 are rotatably connected through the first rotating shaft 6; and / or, the main body 1 has two auxiliary end plates 11 arranged opposite to each other, and the two ends of the movable cover 2 are rotatably connected to the auxiliary end plates 11 through the second rotating shaft 7. The support end plates 34 and the auxiliary end plates 11 respectively increase the strength and stability of the connection parts between the support beam 31 and the movable cover 2, and between the movable cover 2 and the main body 1, to avoid loose connection or damage during frequent rotation and cutting force. The first rotating shaft 6 and the second rotating shaft 7 can provide a low-friction rotation interface for the connecting parts, so that the support beam 31 and the movable cover 2, and between the movable cover 2 and the main body 1 can rotate smoothly around the corresponding axis. For example, the first rotating shaft 6 connects the supporting end plate 34 and the movable cover 2, so that the supporting beam 31 can be accurately rotated to the required angle under the action of the second driving member, thereby meeting the demand for precise adjustment of the cutting angle under different soil conditions; similarly, the second rotating shaft 7 connects the movable cover 2 and the auxiliary end plate 11 of the main body 1, ensuring that the movable cover 2 can be flexibly rotated to accurately change the cutting depth when driven by the first driving member.

[0053] It should be understood that the above-mentioned rotation realization method through the first rotating shaft 6 and the second rotating shaft 7 is only a preferred implementation method for realizing the rotation connection between the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1. Based on the same functional realization requirements, those skilled in the art can realize the rotation connection effect between the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1 through different mechanical forms such as joint bearings, slewing bearings or flexible hinges. Such rotation form replacement schemes based on the principle of equivalent force transmission all belong to the equivalent deformation category of the technical solution of the present invention.

[0054] The first driving member is a first adjusting oil cylinder 4, which includes a first main body 41 and a first telescopic rod 42. The first main body 41 is arranged on the main body 1, and the first telescopic rod 42 is coaxially arranged with the first main body 41 and can be telescopic along its own axial direction. The telescopic end of the first telescopic rod 42 is connected to the movable cover 2. When the cutting depth needs to be adjusted, the first telescopic rod 42 of the first adjusting oil cylinder 4 performs telescopic movement relative to the first main body 41 along its own axial direction under the action of hydraulic pressure. Since the telescopic end of the first telescopic rod 42 is connected to the movable cover 2, the telescopic movement of the first telescopic rod 42 drives the movable cover 2 to rotate around the second rotating shaft 7, thereby changing the inclination angle of the movable cover 2 to achieve the adjustment of the cutting depth.

[0055] The second driving member is a second adjusting oil cylinder 5, which includes a second main body 51 and a second telescopic rod 52. The second telescopic rod 52 is coaxially arranged with the second main body 51 and can be extended and retracted along its own axial direction. The telescopic end of the second telescopic rod 52 is connected to the support beam 31. When the cutting angle needs to be adjusted, the second telescopic rod 52 of the second adjusting oil cylinder 5 is extended and retracted relative to the second main body 51 along its own axial direction under the action of hydraulic pressure. Since the telescopic end of the second telescopic rod 52 is connected to the support beam 31, the extension and retraction of the second telescopic rod 52 drives the support beam 31 to rotate around the first rotating shaft 6, thereby changing the cutting angle of the cutting rake teeth 32.

[0056] Specifically, the second main body 51 is arranged on the movable cover 2, thereby shortening the transmission path between the second driving member and the support beam 31, reducing the energy loss and transmission error that may be caused by the long transmission distance, and improving the response speed and control accuracy of the drive, so as to more accurately adjust the cutting angle.

[0057] Preferably, a first ball joint seat 21 is fixedly connected to the movable cover 2, and the telescopic end of the first telescopic rod 42 is hinged to the first ball joint seat 21; and / or, a second ball joint seat 33 is fixedly connected to the support beam 31, and the telescopic end of the second telescopic rod 52 is hinged to the second ball joint seat 33. The ball joint seat allows the internal hinged part to rotate at a certain angle in multiple directions, thereby enhancing the flexibility of the connection. In the complex stress environment of dredging operations, when the movable cover 2 or the support beam 31 produces unexpected angle changes, twisting or offset due to uneven soil stress, the connection angle can be adaptively adjusted through the first ball joint seat 21 or the second ball joint seat 33 to avoid structural damage and jamming due to rigid connection. At the same time, the ball joint seat helps to disperse stress, so that the force transmitted by the telescopic rod is more evenly distributed, thereby extending the service life of the connecting parts.

[0058] It should be understood that the adjustment method of the first adjustment cylinder 4 and the second adjustment cylinder 5 is only an exemplary embodiment, and those skilled in the art can choose other equivalent drive forms according to actual working conditions. For example, the first drive member can be an electric push rod in combination with a gear rack mechanism, and the motor drives the gear to rotate and drive the rack to move linearly, thereby driving the movable cover 2 to rotate around the hinge axis; the second drive member can also be replaced by a worm gear transmission mechanism, which uses the rotational motion of the worm input shaft to convert it into the angular displacement output of the worm gear and the support beam 31, thereby achieving precise adjustment of the cutting angle. In addition, driving schemes such as a pneumatic actuator and a lever arm combination, a linear motor and a crank slider mechanism can also achieve independent rotation control of the movable cover 2 and the support beam 31. Although the above-mentioned alternatives differ in power source or transmission form, their essence is to achieve decoupling adjustment of the inclination angle of the movable cover 2 and the angle of the support beam 31 by independently controlling the motion output of the two sets of actuators, so they all belong to the equivalent replacement category of the technical concept of the present invention.

[0059] At least two first driving members are provided, and the plurality of first driving members are arranged at intervals along the extension direction of the movable cover 2; and / or at least two second driving members are provided, and the plurality of second driving members are arranged at intervals along the extension direction of the support beam 31. By separately providing a plurality of first driving members and a plurality of second driving members, the movable cover 2 and the support beam 31 can be subjected to force more evenly during the adjustment process, and the movable cover 2 and the support beam 31 can be prevented from being twisted and deformed due to uneven local force, thereby ensuring the accuracy and stability of the cutting depth and angle adjustment. At the same time, in addition, the plurality of driving members provide a redundant design. When problems occur in some of the first driving members or the second driving members, the remaining driving members can still maintain a certain driving and adjustment capability, thereby ensuring that the rake head device continues to work and improving the reliability of the system.

[0060] In this embodiment, two first driving members and two second driving members are respectively provided. In other embodiments, the number of settings can be adaptively adjusted according to actual working conditions, such as setting a single, three, or four first driving members or second driving members, which will not be elaborated here.

[0061] The input module in the control component is used to obtain soil condition parameters. Specifically, the control component also includes a detector, which can be inserted into the soil to be tested, detect and generate soil condition parameters of the soil to be tested, and transmit the soil condition parameters to the input module. Among them, the soil condition parameters include soil compaction, humidity, and composition.

[0062] Specifically, the detector includes a pressure sensor, a humidity sensor and a component analysis sensor. The pressure sensor can measure the compactness of the soil to be tested, and converts the reaction force of the soil to the pressure sensor probe into a corresponding electrical signal or digital signal to reflect the hardness of the soil to be tested. The humidity sensor is used to accurately measure the moisture content in the soil. The component analysis sensor determines the composition of the soil, such as clay, sand or mixed soil, through spectral analysis, chemical testing and other technical means. The soil condition parameters are collected in all directions through the pressure sensor, humidity sensor and component analysis sensor, and converted into a signal form that can be recognized and processed by the calculation module, providing an accurate data basis for subsequent calculations and decisions.

[0063] In addition, it also allows operators to manually input parameters such as soil type and moisture content in the geological survey report through the human-computer interaction interface to improve the adaptability and versatility of the control components.

[0064] The calculation module is used to receive the soil condition parameters transmitted by the input module, and generate the target cutting depth and target cutting angle based on the soil condition parameters. Among them, the target cutting depth refers to the optimal depth value of the tip of the cutting rake 32 vertically cutting into the working surface, which represents the penetration of the cutting rake 32 into the soil layer in the vertical direction; the target cutting angle refers to the optimal angle value formed by the tangent direction of the cutting edge plane of the cutting rake 32 and the contact point of the working surface, which reflects the direction of mechanical action when the cutting rake 32 cuts into the soil layer. In actual operations, the specific values ​​of the above parameters need to be dynamically adapted according to the real-time geological characteristics, the speed of the ship and the construction objectives, and are not limited here.

[0065] The control module is used to control the operation of the first driving member and the second driving member. Specifically, the control module includes a cutting depth unit and a cutting angle unit, both of which are connected to the operation module signal and are used to receive data from the operation module. The cutting depth unit is connected to the first driving member and is used to control the first driving member to drive the movable cover 2 to rotate and monitor the cutting depth in real time; the cutting angle unit is connected to the second driving member and is used to control the second driving member to drive the support beam 31 to rotate and monitor the cutting angle in real time.

[0066] Furthermore, the control component also includes a cutting resistance prediction module, which can predict the cutting resistance faced by the cutting rake 32 when operating at the current cutting depth and cutting angle based on the soil condition parameters obtained by the input module. Since different soil conditions have different effects on cutting resistance, by accurately predicting the cutting resistance, it can be determined whether the current cutting depth and cutting angle are appropriate. If the predicted cutting resistance exceeds a reasonable range, it means that the current cutting parameters may not be conducive to efficient operation or may cause excessive wear and tear on the equipment. At this time, the cutting resistance prediction module automatically calculates the cutting depth and cutting angle that need to be adjusted to return the cutting resistance to a reasonable range based on its internal algorithm. And these new parameter values ​​are passed to the control module, which instructs the first drive member and the second drive member to act accordingly to achieve dynamic adjustment of the cutting depth and angle to adapt to different soil condition parameters.

[0067] Preferably, the control assembly further includes a display component, which is used to display the cutting depth and cutting angle. This allows the operator to intuitively understand whether the cutting depth, cutting angle, etc. meet expectations, so as to make timely adjustments. In addition, the display component can be configured with a human-computer interaction interface, so that the operator can manually input and adjust system parameters. The display component can be a liquid crystal display, a touch screen display, etc., which will not be described in detail here.

[0068] In addition, the control component also includes an accumulation module, which is used to add a certain value based on the existing cutting angle and cutting depth. For example, in some special dredging operation scenarios, when it is necessary to change the cutting depth or cutting angle of a certain area multiple times to achieve a specific excavation effect. Assume that the current cutting depth adjusted by the calculation module and the control module is h 1 , cutting angle is θ 1 , the operator inputs the required increased cutting depth value Δh and cutting angle value Δθ to the accumulation module through the human-computer interaction interface according to actual needs. After receiving the instruction, the accumulation module converts the existing cutting depth h 1 Increase Δh to get a new cutting depth h 2 =h 1 +Δh; change the existing cutting angle θ 1 Increase Δθ to get a new cutting angle θ 2 =θ 1 +Δθ. Then, the accumulation module calculates the new cutting depth h 2 and cutting angle θ 2 The parameters are transmitted to the control module, and the control module controls the operation of the first driving member and the second driving member again according to the new parameters, drives the movable cover 2 and the support beam 31 to rotate, and adjusts the cutting depth and cutting angle to new values ​​to meet special operation requirements.

[0069] It should be noted that the specific implementation principles of the operation module, control module, cutting resistance prediction module and accumulation module involved in the present invention belong to conventional technical means that can be understood and implemented by those skilled in the art. The core innovation of the technical solution of the present invention is to achieve the technical effect of adjusting the cutting depth and cutting angle through the coordination of specific structural design and the above-mentioned control components. Therefore, the conventional technical contents such as the underlying operation details of the operation module, control module, cutting resistance prediction module and accumulation module will not be elaborated here.

[0070] Embodiment 2

[0071] Figure 3 and Figure 4 Embodiment 2 is shown, in which the parts identical or corresponding to those in embodiment 1 are marked with the corresponding reference numerals in embodiment 1. For the sake of simplicity, only the differences between embodiment 2 and embodiment 1 are described. The difference is that, considering that the inclination angle adjustment range of the cutting rake teeth 32 is large when operating on certain soil bodies, the stroke of the second telescopic rod 52 is relatively long. Therefore, the second main body 51 is arranged on the main body 1. Therefore, when facing certain soil operation scenes that require a larger cutting angle adjustment range, since the distance between the main body 1 and the support beam 31 is greater than the distance between the movable cover 2 and the support beam 31, the moving path of the second telescopic rod 52 is increased. The larger moving path enables the second telescopic rod 52 to have a more sufficient stroke to realize a larger angle rotation of the support beam 31, thereby meeting the demand for a large range of cutting angle adjustment.

[0072] Embodiment 3

[0073] The embodiment of the present invention further provides a method for using an adjustable drag head device, which is applied to the adjustable drag head device provided in the first embodiment, and the specific steps include:

[0074] S1. Obtain soil condition parameters;

[0075] In this step, the detector is inserted into the soil to be tested, the soil condition parameters of the soil to be tested are detected and generated, and transmitted to the input module, and the operator manually inputs the soil condition parameters through the human-computer interaction interface.

[0076] S2, generating a target cutting depth and a target cutting angle based on soil condition parameters;

[0077] In this step, the input module passes the acquired soil condition parameters to the operation module. The operation module analyzes the soil condition parameters through an algorithm and generates the corresponding target cutting depth and target cutting angle according to the actual working conditions.

[0078] S3, controlling the first driving member to drive the movable cover 2 to rotate until the cutting depth reaches the target cutting depth; controlling the second driving member to drive the support beam 31 to rotate until the cutting angle reaches the target cutting angle.

[0079] In this step, the control module adjusts the hydraulic system so that the first telescopic rod 42 can telescope relative to the first main body 41 along its own axial direction under the action of hydraulic pressure. Since the first telescopic rod 42 is connected to the movable cover 2, its telescopic movement drives the movable cover 2 to rotate around the second rotating shaft 7, thereby changing the inclination angle of the movable cover 2 and directly controlling the vertical cutting amount of the cutting rake teeth 32. In this process, the control module continuously monitors the cutting depth and compares it with the target cutting depth. When the cutting depth does not reach the target value, the telescopic amount of the first telescopic rod 42 is continuously fine-tuned until the cutting depth reaches the target cutting depth. Similarly, the control module controls the hydraulic system so that the second telescopic rod 52 can telescope relative to the second main body 51 along its own axial direction under the action of hydraulic pressure. Since the second telescopic rod 52 is connected to the support beam 31, its telescopic movement drives the support beam 31 to rotate around the first rotating shaft 6, thereby changing the contact angle between the multiple cutting rake teeth 32 arranged along the extension direction of the support beam 31 and the surface to be cut. The control module monitors the cutting angle in real time and compares it with the target cutting angle. When the cutting angle does not reach the target value, the extension amount of the second telescopic rod 52 is adjusted in time until the cutting angle reaches the target cutting angle, until the optimal construction state is achieved.
