Description

Technical Field

[0001] This utility model generally relates to the field of submarine cable laying technology, and specifically to a balancing device for a laying plow and a laying plow having the same. Background Technology

[0002] During the laying of submarine cables, a burial plow is needed to create trenches on the seabed, and these trenches are used to bury the submarine cables. Chinese Patent (Publication No. CN113802633A) discloses an angle-adjustable burial plow, which includes a frame. The bottom of the frame is provided with legs and skids for supporting the frame. There is one leg and one skid on each side of the frame in the width direction. Both legs can be rotatably set to adjust the digging depth of the burial plow, and both skids can be rotatably set to maintain the balance of the burial plow.

[0003] When the soil conditions for laying plows change from hard soil to extremely soft soil, it is usually necessary to temporarily install floating plates on the skids to prevent them from sinking into the extremely soft soil. However, the installation of these floating plates is cumbersome, and when the floating plates are not in use, the operators also need to store them, which increases the workload of the operators. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a balancing device for a burial plow and a burial plow having the same.

[0005] In a first aspect, this application provides a balancing device for a buried plow, comprising:

[0006] A balance adjustment plate, which includes a pressing section for pressing against the ground;

[0007] A pressure-reducing plate is disposed in the pressing section and is movably disposed to move between an unfolded position and a retracted position. In the unfolded position, the pressure-reducing plate extends out of the pressing section along the width direction of the balance adjustment plate, and in the retracted position, the projection of the pressure-reducing plate along the thickness direction of the balance adjustment plate is located within the projection range of the pressing section.

[0008] Furthermore, the crimping section is provided with a receiving cavity, and the crimping section has a first opening communicating with the receiving cavity on at least one side along the width direction. The pressure reducing plate is disposed in the receiving cavity and enters and exits the receiving cavity through the first opening.

[0009] Furthermore, an annular elastic seal is provided at the first opening, and the elastic seal abuts against the pressure reducing plate. A guide assembly is provided between the accommodating cavity and the pressure reducing plate. The guide assembly includes a guide rod and a guide hole for guiding engagement. The guide rod is disposed in the cavity wall opposite to the first opening in the accommodating cavity, and the axial direction of the guide rod is parallel to the width direction of the pressing section. The guide hole is disposed in the pressure reducing plate, and the guide rod is inserted into the guide hole.

[0010] Furthermore, it also includes a mounting plate, which is disposed at the first opening and detachably fixedly connected to the crimping section. The mounting plate has a second opening that exposes the first opening, and an elastic seal is disposed at the second opening.

[0011] Furthermore, the mounting plate has an annular extension on the side near the receiving groove. The extension extends into the receiving cavity and fits against the cavity wall. At least a portion of the elastic seal is provided in the extension.

[0012] Furthermore, the outer periphery of the pressure reducing plate is provided with a protrusion, which is located at the end of the pressure reducing plate away from the opening. The protrusion slides in fit with the receiving cavity, and the protrusion and the extension can abut against each other in the width direction of the pressing section.

[0013] Furthermore, the protrusion includes two first protrusions and two second protrusions. The two first protrusions are respectively disposed on both sides of the pressure reducing plate along the length direction of the pressing section, and the two second protrusions are respectively disposed on both sides of the pressure reducing plate along the thickness direction of the pressing section. The two first protrusions and the two second protrusions are staggered along the width direction of the pressing section.

[0014] Furthermore, it also includes a drive mechanism disposed in the pressing section, which is connected to the pressure reducing plate to drive the pressure reducing plate to move.

[0015] Furthermore, there are two pressure-reducing plates, which are arranged along the width direction of the crimping section. In the unfolded position, the two pressure-reducing plates extend out of the crimping section in opposite directions.

[0016] Secondly, this application also provides a burying plow, including the aforementioned balancing device.

[0017] The balancing device for the burial plow and the burial plow having the same provided in this application have a pressure-reducing plate provided in the pressing section of the balancing adjustment plate. When the pressure-reducing plate is switched from the storage position to the unfolded position, it extends out of the pressing section along the width direction of the balancing adjustment plate to increase the width of the balancing device. This makes it possible for workers to temporarily install floating plates on the balancing device when the burial plow's working environment is switched to extremely soft soil, thus avoiding the need for workers to perform floating plate installation operations and store idle floating plates, and reducing the workload of the workers. Attached Figure Description

[0018] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0019] Figure 1 A schematic diagram of the balancing device provided in the embodiments of this application when the pressure reducing plate is in the deployed position;

[0020] Figure 2 This is a schematic diagram of the pressure relief plate provided in the embodiment of this application when it is in the storage position. Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] Please refer to the attached document. Figure 1-2 This application provides a balancing device for burying a plow, including a balancing adjustment plate 100 and a pressure-reducing plate 200. The balancing adjustment plate 100 includes a pressing section 120, which presses the balancing adjustment plate 100 against the seabed surface. The pressure-reducing plate 200 is disposed on the pressing section 120 and is movably disposed to move between an extended position and a retracted position. Specifically, in the extended position, the pressure-reducing plate 200 extends beyond the pressing section 120 along the width direction of the balancing adjustment plate 100, at which time the effective width of the pressing section 120 increases, that is, the effective extended area of ​​the balancing device increases; in the retracted position, the projection of the pressure-reducing plate 200 along the thickness direction of the balancing adjustment plate 100 is within the projection range of the pressing section 120, at which time the effective width of the pressing section 120 is at its minimum and is equal to the width of the pressing section 120 itself.

[0023] In this embodiment, when the working scene of the burying plow is switched from hard soil to extremely soft soil, it is only necessary to switch the pressure relief plate 200 from the storage position to the unfolded position to increase the effective width of the contact between the balancing device and the extremely soft soil, prevent the pressing section 120 from sinking into the extremely soft soil, and eliminate the need for workers to temporarily install floating plates on the balancing device, thus avoiding the need for workers to perform floating plate installation operations and store idle floating plates, reducing the workload of the operators.

[0024] Optionally, the balance adjustment plate 100 includes a straight plate section 110 and a pressing section 120 connected together. The pressing section 120 is arc-shaped. The straight plate section 110 is rotatably connected to the frame of the burial plow and the axis of rotation is perpendicular to the trenching direction of the burial plow. A hydraulic cylinder is provided between the pressing section 120 and the frame, and the balance adjustment plate 100 is driven to rotate by the hydraulic cylinder to adjust the flatness of the burial plow when it is working on extremely soft soil.

[0025] The pressure-reducing plate 200 can have one or more unfolded positions. When it has multiple unfolded positions, the width of the portion of the pressure-reducing plate 200 extending out of the receiving cavity differs depending on the unfolded position. Furthermore, the position of the pressure-reducing plate 200 can be adjusted during operation by a drive mechanism. The drive mechanism is located on the top side of the pressing section 120 and connected to the pressure-reducing plate 200 to drive the pressure-reducing plate 200 to move. The drive mechanism can be, but is not limited to, a hydraulic cylinder, and there can be multiple hydraulic cylinders. A connecting rod connects the hydraulic cylinder and the pressure-reducing plate 200, with both ends of the connecting rod hinged to the drive rod of the hydraulic cylinder and the end of the pressure-reducing plate 200, respectively.

[0026] In some embodiments of this application, the crimping section 120 is provided with a receiving cavity, and the pressure reducing plate 200 is disposed in the receiving cavity. The crimping section 120 has a first opening communicating with the receiving cavity on at least one side along the width direction, and the first opening allows the pressure reducing plate 200 to enter and exit the receiving cavity. This arrangement not only reduces the overall weight of the balancing device, but also allows the balancing adjustment plate 100 to provide structural protection for the pressure reducing plate 200, which helps to improve the reliability of the pressure reducing plate 200.

[0027] Specifically, in the unfolded position, the pressure relief plate 200 extends out of the receiving cavity through the first opening; in the retracted position, the portion of the pressure relief plate 200 extending out of the receiving cavity retracts into the receiving cavity, at which point the entire pressure relief plate 200 is located inside the receiving cavity.

[0028] In some embodiments of this application, an annular elastic seal 320 is provided at the first opening. The elastic seal 320 abuts against the pressure reducing plate 200 to seal the accommodating cavity, preventing external impurities such as mud and sand from entering the accommodating cavity through the opening and ensuring that the pressure reducing plate 200 can move smoothly. The elastic seal 320 can be, but is not limited to, a rubber sealing ring, etc.

[0029] A guide assembly is provided between the receiving cavity and the pressure reducing plate 200. The guide assembly includes a guide rod and a guide hole for guiding engagement. The guide rod is disposed in the cavity wall opposite to the first opening in the receiving cavity, and the axial direction of the guide rod is parallel to the width direction of the pressing section 120. The guide hole is disposed in the pressure reducing plate 200, and the guide rod is inserted into the guide hole. The above-mentioned guide assembly can constrain the pressure reducing plate 200 to move centrally relative to the elastic seal 320, ensuring that the circumferential contact pressure between the elastic seal 320 and the pressure reducing plate 200 remains consistent, thereby improving the sealing uniformity of the elastic seal 320.

[0030] Optionally, there may be multiple guide components, and these multiple guide components may be spaced apart along the length of the crimping section 120. This arrangement can increase the stability of the pressure relief plate 200 during movement.

[0031] In some embodiments of this application, a mounting plate 310 is also included. The mounting plate 310 is disposed at the first opening and detachably fixedly connected to the crimping section 120. The mounting plate 310 has a second opening that exposes the first opening, and the elastic seal 320 is disposed in the second opening. With this configuration, it is not necessary to remove the pressure reducing plate 200 when replacing the elastic seal 320, making the replacement of the elastic seal 320 simple and convenient.

[0032] Optionally, the mounting plate 310 and the crimping section 120 are screwed together.

[0033] In some embodiments of this application, the mounting plate 310 has an annular extension 311 on the side near the receiving groove. The extension 311 extends into the receiving cavity and fits against the cavity wall. At least a portion of the elastic seal 320 is disposed in the extension 311. This arrangement allows the elastic seal 320 to be disposed wider, improving its sealing performance and increasing the bonding area between the elastic seal 320 and the mounting plate 310, thus enhancing the connection strength between them. Furthermore, the extension 311 also facilitates the precise installation of the mounting plate 310 onto the crimping section 120.

[0034] In some embodiments of this application, the pressure-reducing plate 200 has a protrusion on its outer periphery. The protrusion is located at the end of the pressure-reducing plate 200 away from the opening. The protrusion slides with the receiving cavity, and the protrusion and the extension 311 abut against each other in the width direction along the pressing section 120. The protrusion guides the pressure-reducing plate 200 to be inserted into the receiving cavity along a set path. When the pressure-reducing plate 200 is inserted into the receiving cavity along the set path, the guide hole and the guide rod are coaxially arranged, realizing automatic and precise insertion and engagement between the guide rod and the guide hole when the pressure-reducing plate 200 is inserted into the receiving cavity, thereby improving the assembly efficiency of the balancing device.

[0035] Optionally, the protrusion includes two first protrusions 210 and two second protrusions 220. The two first protrusions 210 are respectively disposed on both sides of the pressure reducing plate 200 along the length direction of the pressing section 120, and the two second protrusions 220 are respectively disposed on both sides of the pressure reducing plate 200 along the thickness direction of the pressing section 120. The two first protrusions 210 and the two second protrusions 220 are staggered along the width direction of the pressing section 120.

[0036] During the insertion of the pressure reducing plate 200 into the accommodating cavity, one of the first protrusions 210 and one of the second protrusions 220 closest to the opening are first kept in contact with the cavity wall of the accommodating cavity. Then, during the subsequent insertion process, the other first protrusion 210 and the other second protrusion 220 are kept in contact with the cavity wall of the accommodating cavity, making the insertion of the pressure reducing plate 200 into the accommodating cavity simple and convenient.

[0037] In some embodiments of this application, there are two pressure-reducing plates 200, and the two pressure-reducing plates 200 are arranged along the width direction of the crimping section 120. In the unfolded position, the two pressure-reducing plates 200 extend out of the crimping section 120 in opposite directions. The above arrangement enables the crimping section 120 to be widened on both sides, increasing structural balance.

[0038] Optionally, the crimping section 120 has receiving grooves on both sides along its width, and the two receiving grooves are not connected, with the inner cavity of the receiving groove forming a receiving cavity. The crimping section 120 also has first openings on both sides along its width to allow two pressure-reducing plates 200 to be respectively inserted into the two receiving grooves. The crimping section 120 has a partition wall located between the two receiving grooves, separating the two receiving cavities, with a guide rod disposed on the partition wall. Each pressure-reducing plate 200 is moved under the drive of at least one driving mechanism.

[0039] This application also provides a burying plow, including a frame and balancing devices respectively disposed on both sides of the frame.
