Description

Technical Field

[0001] This utility model relates to the technical field of underground continuous wall construction equipment, and in particular to an integrated trenching and core planting machine. Background Technology

[0002] In current construction processes, trenching and core wall installation for diaphragm walls are typically separated into two independent procedures. First, trenching equipment is used to cut a trench of the predetermined shape in the foundation; this process requires the injection of wall-supporting slurry to maintain trench wall stability. After trenching is completed, the trenching equipment is removed from the work surface, and then other hoisting or specialized equipment transports the prefabricated slab-shaped core to the trench location and inserts it. This step-by-step construction method has significant efficiency bottlenecks; equipment entry and exit and coordination consume a considerable amount of time, resulting in a long overall construction cycle.

[0003] Furthermore, due to the separation of the two processes, it is difficult for the equipment subsequently implanting the core wall to be accurately positioned relative to the completed trench. In practice, positioning deviations can easily cause the core wall to fail to be centered within the trench, or even collide with the trench wall, affecting the integrity and load-bearing capacity of the wall structure. Simultaneously, the lack of effective linkage control between the separated equipment results in poor coordination, further increasing the uncertainty of the construction process and the difficulty of quality control.

[0004] For the core wall implantation process, existing guidance methods are often quite simple and lack effective correction and buffering measures. When implanting long, plate-shaped cores, jamming or tilting can easily occur due to excessive friction or inaccurate guidance, especially when the foundation is uneven, making it difficult to ensure the verticality of the core wall. This not only affects implantation efficiency but may also damage the already formed trench wall and the core itself.

[0005] Therefore, existing technologies suffer from technical problems such as low construction efficiency, disjointed process connections, poor positioning accuracy, and easy deviation during implantation. There is an urgent need for an integrated solution that can efficiently integrate trenching and core implantation processes and ensure construction quality. Summary of the Invention

[0006] To address the aforementioned issues, the present invention aims to provide an integrated trenching and core planting machine, which offers advantages such as shortening the construction cycle, improving positioning accuracy, and reducing equipment interference.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This application provides an integrated trenching and coring machine, the technical solution of which is as follows: the trenching machine and the automatic coring machine are each equipped with an independent tracked walking mechanism and a hydraulic drive device for driving the walking mechanism; the automatic coring machine is softly connected to the tail of the trenching machine through a flexible connecting device; the hydraulic drive devices of the trenching machine and the automatic coring machine are connected through a delivery oil pipe and are uniformly controlled by a system control unit installed on the trenching machine; the flexible connecting device is used to prevent the delivery oil pipe from disengaging due to excessive distance between the two.

[0009] Furthermore, this application also proposes that the flexible connection device includes an iron chain.

[0010] Furthermore, this application also proposes that the automatic core implantation machine includes: a chassis structure with a tracked walking mechanism inside; a core implantation guide frame with its lower end hinged to one side edge of the chassis structure; at least one inclined hydraulic cylinder with its lower end hinged to the other side edge of the chassis structure and its upper end hinged to the top of the core implantation guide frame; the inclined hydraulic cylinder is used to adjust the verticality of the core implantation guide frame.

[0011] Furthermore, this application also proposes that multiple surrounding rods are arranged longitudinally on the core implantation guide frame to form a core plate channel; a guide wheel is provided in the enclosed area of ​​each surrounding rod, and the guide wheel is used to fit against the surface of the core plate during implantation to guide the core plate downward and reduce friction.

[0012] Furthermore, this application also proposes that the enclosed area of ​​the fence is U-shaped, and two guide wheels are provided inside the U-shaped opening.

[0013] Furthermore, this application also proposes that the automatic core implantation machine further includes an anti-derailment roller mechanism, which is mounted on the chassis structure; the anti-derailment roller mechanism includes at least two vertically arranged roller shafts, which are adapted to extend into the formed groove and roll along the groove wall to ensure that the automatic core implantation machine travels along the center line of the groove.

[0014] Furthermore, this application also proposes that a crane be used above the core implantation guide frame to press the core plate into the core implantation guide frame from the top.

[0015] Furthermore, this application also proposes that the flexible connection device allows the automatic core implanter to deflect at a certain angle in the horizontal direction relative to the trenching machine.

[0016] Furthermore, this application also proposes that the iron chain constitutes a buffer mechanism to mitigate the relative motion impact between the trenching machine and the automatic core implantation machine.

[0017] As can be seen from the above, the trenching and core planting integrated machine and its flexible connection device and automatic core planting mechanism provided in this application are provided with independent tracked walking mechanisms and hydraulic drive devices for driving the walking mechanisms. The flexible connection device enables collaborative operation, shortens the construction cycle, improves positioning accuracy, and reduces equipment interference. It has the advantages of shortening the construction cycle, improving positioning accuracy, and reducing equipment interference. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In existing technologies, diaphragm wall construction typically employs a phased operation mode, with trenching and core planting processes completed independently by different equipment. After trenching equipment completes excavation, it must leave the site before other equipment can implant the core wall, resulting in low efficiency in process coordination. Due to the lack of inter-equipment control, subsequent core planting equipment struggles to accurately position the trench centerline, easily leading to core wall misalignment or collision with the trench wall. Existing core planting guiding mechanisms lack dynamic correction capabilities, and long core plates are prone to jamming due to frictional resistance during implantation, affecting construction quality and efficiency.

[0028] To address the aforementioned issues, the inventors discovered that the core contradiction of process separation lies in the spatiotemporal misalignment and lack of coordination caused by the independent operation of equipment. Traditional solutions attempt to improve efficiency by optimizing the performance of individual machines, but fail to address the fundamental problem of process integration. By analyzing the independence of the tracked walking mechanism and the feasibility of physical connections between equipment, they proposed physically coupling the trenching machine and the core implantation machine to establish control coordination while maintaining their respective degrees of freedom of movement. For the hydraulic system's linkage requirements, a split-drive device combined with a central control strategy is adopted, which avoids excessive complexity of the power system while achieving synchronized actions.

[0029] like Figure 1-4As shown, this embodiment proposes an integrated trenching and coring machine, including a trenching machine 1 and an automatic coring machine 2. The trenching machine 1 and the automatic coring machine 2 are each equipped with an independent tracked walking mechanism 3 and a hydraulic drive device for driving the walking mechanism. The automatic coring machine 2 is flexibly connected to the tail of the trenching machine 1 via a flexible connecting device 5. The hydraulic drive devices of the trenching machine 1 and the automatic coring machine 2 are connected via oil delivery pipes 6 and are uniformly controlled by the system control unit 7 on the trenching machine 1. The flexible connecting device 5 is used to prevent the oil delivery pipes 6 from disengaging due to excessive spacing.

[0030] Among them, the tracked walking mechanism 3 refers to a ground moving device composed of continuous track plates, specifically implemented using a steel track and drive wheel meshing structure, enabling the equipment to walk autonomously. The hydraulic drive device refers to a drive system that transmits power through a hydraulic motor, specifically implemented using a combination of a variable pump and a piston motor, providing adjustable walking drive force. The flexible connection device 5 refers to a mechanical connection component that allows relative displacement, specifically implemented using a chain or articulated linkage structure, forming a physical connection between the equipment. The system control unit 7 refers to the operating unit that centrally controls the hydraulic system, specifically implemented using a PLC controller and hydraulic valve group working in tandem to synchronously adjust the walking speed and direction of the two devices.

[0031] Specifically, the trenching machine 1 and the core planting machine maintain mobility through independent walking mechanisms, allowing for adaptive adjustments to their routes in complex terrain. The flexible connection device 5 creates physical constraints between the devices, ensuring that the delivery oil pipe 6 remains within its effective connection length. The system control unit 7 monitors the relative positions of the two devices in real time and adjusts the output parameters of the hydraulic drive to maintain a preset distance between them. When the trenching machine 1 turns or changes speed, the core planting machine follows through the buffering effect of the flexible connection, avoiding motion interference caused by rigid connections. The interconnected oil circuit design of the hydraulic drive ensures more balanced power distribution, reducing system pressure fluctuations caused by sudden changes in single-machine load. Compared to existing technologies, traditional split-type equipment requires repeated entry and exit from the site, while this solution achieves continuous operation through physical connection and coordinated control, eliminating process intervals. Existing core planting equipment relies on manual positioning of the trench; this solution ensures the core planting machine always travels along the trenching trajectory through linked control of the walking mechanism. Traditional rigid connections easily cause equipment motion interference; this solution's flexible connection allows for moderate deflection while maintaining equipment connectivity, adapting to complex construction environments.

[0032] In the specific design, the flexible connection device 5 includes a chain. The chain is a mechanical component formed by multiple links connected by hinges. Specifically, it can be achieved by nesting and interlocking elliptical chain links forged from metal. The hinged structure between the links allows the chain to undergo multi-directional displacement during stretching and bending. The combination of mechanical flexibility and rigidity of the chain allows it to maintain a physical connection while bearing the weight of the equipment and the impact of movement. Simultaneously, the relative rotation between the links absorbs the relative displacement deviation between the trenching machine 1 and the automatic core-planting machine 2. Specifically, the two ends of the chain are fixed to the tail of the trenching machine 1 and the front of the automatic core-planting machine 2, respectively. When the distance between the two devices changes due to differences in construction terrain or travel speed, the chain undergoes elastic deformation through the hinged rotation between the links, thus adapting to longitudinal stretching or lateral deflection. For example, when the trenching machine 1 suddenly accelerates, the chain extends its connection length by gradually unfolding its links, avoiding the instantaneous tension concentration caused by a rigid connection. When the automatic core implantation machine 2 shifts laterally due to uneven ground, the chain maintains its connection by adjusting the lateral deflection angle of its links. As a result, the oil delivery pipe 6 is always within the connection range formed by the chain, preventing the oil pipe from disengaging or bending and breaking due to excessive spacing.

[0033] Furthermore, the chain constitutes a buffer mechanism to mitigate the impact of relative motion between the trenching machine 1 and the automatic core-planting machine 2. The multi-link hinged structure of the chain is designed to absorb the instantaneous impact force between the equipment through the relative rotation between the links, avoiding stress concentration. The buffer mechanism refers to a device that disperses impact energy through mechanical deformation or displacement, specifically utilizing the ductility and oscillation characteristics of the chain. The oscillation of the chain links is used to convert the relative motion between the equipment into localized deformation of the chain links, thereby reducing the amplitude of mechanical vibration.

[0034] This application further proposes a flexible connecting device 5 that allows the automatic core implanter 2 to deflect at a certain angle relative to the trenching machine 1 in the horizontal direction. This horizontal deflection refers to the lateral offset that can occur between the automatic core implanter 2 and the trenching machine 1 during travel. Specifically, the deflection angle can be limited by the swing range of the chain to adapt to uneven ground or turning requirements, while preventing excessive deflection from causing the equipment to deviate from its predetermined path. In detail, the flexible connecting device 5 utilizes the flexibility of the chain to allow the automatic core implanter 2 to deflect at an angle relative to the trenching machine 1 in the horizontal direction. When encountering uneven ground or needing to turn, the automatic core implanter 2 can adjust its direction of travel according to the terrain changes without needing to maintain complete synchronization with the trenching machine 1. The swing range of the chain is controlled by a limiting mechanism to ensure that the deflection angle is within the allowable range, preventing the oil delivery pipe 6 from disengaging due to sudden changes in spacing and preventing the equipment's trajectory from deviating from the centerline of the trench. The direction of travel of the automatic core implantation machine 2 is corrected in real time by the anti-derailment roller mechanism. The roller shaft 15 rolls along the groove wall to maintain the alignment of the center line, while the horizontal deflection capability of the flexible connection device 5 further reduces the motion interference between the equipment and improves the overall coordination.

[0035] like Figure 3 and 4 As shown, the automatic core implantation machine 2 includes a combination of a chassis structure 9, a core implantation guide frame 10, and a diagonal hydraulic cylinder 11. The chassis structure 9 houses a tracked walking mechanism 3. The lower end of the core implantation guide frame 10 is hinged to one edge of the chassis structure 9, and the lower end of the diagonal hydraulic cylinder 11 is hinged to the other edge of the chassis structure 9, while its upper end is hinged to the top of the core implantation guide frame 10. The diagonal hydraulic cylinder 11 is used to adjust the verticality of the core implantation guide frame 10. The chassis structure 9 refers to the frame-type foundation platform that supports the main components of the automatic core implantation machine 2. Specifically, it can be implemented using a box-shaped structure formed by welding steel plates. Its internal space is used to accommodate the transmission components of the walking mechanism and to provide an installation interface for the upper structure. The core implantation guide frame 10 is a rigid guiding device used to constrain the core board implantation path. Specifically, it can be implemented using a truss structure formed by welding multiple longitudinal beams and transverse braces. Its lower end hinged design allows the guide frame to deflect at an angle around the edge of the chassis. The inclined hydraulic cylinder 11 refers to a linear actuator driven by hydraulic pressure. Specifically, it can be implemented by a double-acting piston hydraulic cylinder. The symmetrical layout of the hinge points at both ends enables the cylinder to apply tension or thrust to the guide frame when it extends or retracts.

[0036] Specifically, when the automatic core implantation machine 2 tilts due to uneven ground during movement, the inclined hydraulic cylinder 11 changes the tilt angle of the core implantation guide frame 10 through real-time extension and retraction. For example, when the guide frame is detected to have shifted to the left, the right inclined hydraulic cylinder 11 can extend, applying a rightward pulling force to the guide frame through the top hinge point, restoring it to a vertical state. Since the guide frame and chassis are hinged symmetrically on both sides, the adjustment force of the hydraulic cylinder can directly act on the top of the guide frame, forming an effective torque balance. This dynamic adjustment mechanism ensures that the core plate always moves vertically downward during implantation, avoiding core plate positioning deviation caused by the tilt of the equipment itself. Through the above technical solution, this application realizes dynamic verticality adjustment during the core plate implantation process, solving the technical problem of guide frame tilting caused by uneven foundation. During continuous construction, the inclined hydraulic cylinder 11 can automatically compensate for changes in equipment posture based on real-time detection data, ensuring that the core plate is always implanted into the center position of the trench along the preset vertical path, avoiding core plate jamming or trench wall collision caused by tilting.

[0037] like Figure 4 As shown, multiple supporting rods 12 are arranged longitudinally on the core implantation guide frame 10 to form a core plate channel. A guide wheel 13 is provided within the enclosed area of ​​each supporting rod 12. The guide wheel 13 is used to contact the surface of the core plate during implantation to guide the core plate downwards and reduce friction. The supporting rods 12 are support components spaced longitudinally along the core implantation guide frame 10. They can be fixed to the guide frame body by welding or bolting metal profiles, forming a continuous core plate channel, constraining the vertical movement trajectory of the core plate, and preventing displacement due to uneven foundation or external interference. The guide wheels 13 are rotatable rolling components. They can be a combination of bearings and wear-resistant rubber wheels embedded within the enclosed area of ​​the supporting rods 12. By rolling into contact with the core plate surface, sliding friction is converted into rolling friction, thereby reducing downward resistance. Simultaneously, the contact pressure is adaptively adjusted to prevent the core plate from jamming or being damaged.

[0038] Specifically, the longitudinally arranged support rods 12 form a continuous U-shaped channel structure, restricting the core plate's movement within the channel during implantation and ensuring its descent along a predetermined path. Guide wheels 13 are embedded within the enclosed area of ​​each support rod 12. When the core plate surface contacts the guide wheel 13, the guide wheel 13 rolls as the core plate descends, reducing contact resistance by replacing sliding friction with rolling friction. The guide wheel 13 dynamically adheres to the core plate surface, adjusting its contact position by rolling when the core plate slightly shifts, preventing excessive local pressure that could cause jamming. The combined structure of the support rods 12 and guide wheels 13 forms a multi-stage guiding and drag-reducing mechanism, ensuring the core plate maintains a vertical posture and descends smoothly during implantation. In a further preferred embodiment, the enclosed area of ​​the support rods 12 is U-shaped, with two guide wheels 13 positioned inside the U-shaped opening. The U-shaped enclosed area refers to a semi-enclosed channel structure with directional guiding function formed by the support rods 12, whose opening width is slightly larger than the core plate thickness, used to constrain lateral shift of the core plate.

[0039] like Figure 1 and 4 As shown, the automatic core implantation machine 2 also includes an anti-derailment roller mechanism, which is mounted on the chassis structure 9. The anti-derailment roller mechanism includes at least two vertically arranged roller shafts 15. The roller shafts 15 are adapted to extend into the formed groove and roll along the groove wall to ensure that the automatic core implantation machine 2 travels along the centerline of the groove. The anti-derailment roller mechanism refers to a mechanical guiding device mounted on the chassis structure 9. Specifically, it can be implemented by combining a rigid bracket with bearings with the roller shafts 15, forming a physical limit through the rolling contact between the roller shafts 15 and the groove wall. The roller shafts 15 are cylindrical components installed perpendicular to the ground, specifically steel shafts covered with wear-resistant material, whose vertical extension length adapts to grooves of different depths. Rolling along the groove wall means that the outer circumferential surface of the roller shafts 15 remains in contact with the groove wall. This can be achieved by adjusting the horizontal position of the roller shafts 15 to create a pre-tension force with the groove wall, using the geometric constraints of the groove wall to limit the lateral deviation of the equipment.

[0040] Specifically, the anti-derailment roller mechanism uses two vertically arranged roller shafts 15 extending into the tank wall areas on both sides of the tank. When the automatic core implantation machine 2 moves, the roller shafts 15 generate rolling friction under the squeezing action of the tank wall, and the reaction force exerted by the tank wall on the roller shafts 15 forms a symmetrical balance. At this time, the horizontal displacement of the roller shafts 15 is restricted by the physical boundary of the tank wall, forcing the trajectory of the automatic core implantation machine 2 to always be in the direction of the center line of the tank. When the equipment tends to deviate laterally due to uneven ground or driving error, the contact pressure between the roller shaft 15 on the deviated side and the tank wall increases, and the resistance generated by rolling friction offsets the deviation force, thereby maintaining the equipment moving along the predetermined path. Through the above technical solution, this application can forcibly guide the automatic core implantation machine 2 to move along the center line of the tank, avoiding the core wall from deviating from the design position or colliding with the tank wall due to positioning deviation. The continuous contact between the roller shafts 15 and the tank wall can correct the direction of the equipment's movement in real time, ensuring that the core wall implantation position coincides with the axis of the tank, thereby improving the alignment accuracy and overall load-bearing capacity of the wall structure.

[0041] In a specific implementation plan, a crane is used above the core implantation guide frame 10 to press the core plate into the core from the upper end of the core implantation guide frame 10.

[0042] The crane refers to a lifting device capable of applying vertical pressure. Specifically, it can be a hydraulically driven winch mechanism combined with wire rope traction. By controlling the lifting and lowering motion of the winch, continuous downward pressure is applied to the core board. The core-planting guide frame 10 refers to a frame structure with longitudinally arranged surrounding rods 12. Specifically, U-shaped surrounding rods 12 can form a core board channel. Guide wheels 13 are installed on the inner side of the surrounding rods 12, contacting the core board surface to limit lateral displacement and reduce frictional resistance. In detail, during core board implantation, the crane's wire rope is connected to the top of the core board, and a constant downward pressure is applied by the winch. After the core board enters the U-shaped channel of the core-planting guide frame 10, the guide wheels 13 contact the sides of the core board, creating rolling friction. The vertical pressure of the crane overcomes the static friction between the core board and the channel wall. As the crane continues to press down, the core board descends vertically along the path defined by the guide frame, and the rolling guide wheels 13 prevent the core board from colliding hard with the surrounding rods 12. When uneven foundation causes the guide frame to tilt slightly, the vertical force applied by the crane is superimposed on the direction of gravity, forcing the core plate to always move along the axis of the guide frame, preventing jamming or deflection caused by increased friction on one side.

[0043] In summary, the trenching and core planting integrated machine and its flexible connection device and automatic core planting mechanism provided in this application are provided with independent tracked walking mechanism 3 and hydraulic drive device for driving the walking mechanism, respectively. The flexible connection device 5 enables collaborative operation, shortens the construction cycle, improves positioning accuracy, and reduces equipment interference. It has the advantages of shortening the construction cycle, improving positioning accuracy, and reducing equipment interference.
