Description

Technical Field

[0001] This utility model relates to the technical field of geotextile laying, specifically a machine for underwater geotextile laying used in combination with a long-arm excavator. Background Technology

[0002] Geotextile is a permeable geosynthetic material made of synthetic or natural fibers through needle punching, weaving and other processes. It has the characteristics of high tensile strength, corrosion resistance, aging resistance and good permeability. It is widely used in water conservancy, transportation, construction and other engineering fields. It mainly plays the roles of filtration, drainage, isolation, reinforcement and seepage prevention. It is an important auxiliary material for improving the quality of projects and extending the service life of projects.

[0003] When laying geotextiles, first clean the construction area, remove debris, and level the ground or underwater base. Cut the geotextiles according to the design dimensions. Lay the geotextiles flat on the base, avoiding wrinkles and pulling. Then, fix the fabric with sandbags, anchors, or sewing to prevent displacement. Finally, check the laying quality to ensure there is no damage or missing joints. In some cases, a protective layer needs to be covered on the geotextiles to complete the entire laying operation.

[0004] Most existing geotextile laying equipment is used for laying on the ground. When it is necessary to lay geotextiles underwater in dams, it will cause difficulties. Therefore, in order to solve the above problems, a machine for laying geotextiles underwater in combination with a long-arm excavator is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides an underwater geotextile laying tool used in conjunction with a long-arm excavator, comprising a mechanical arm; a pair of fixing pins are fixedly connected to the bottom end of the mechanical arm; a first fixed seat is fixedly connected to the bottom end of the mechanical arm; the fixing pins are connected to the first fixed seat; a support plate is provided at the bottom end of the first fixed seat; a pair of first hydraulic rods are hinged to the bottom end of the support plate; a support frame is hinged to the bottom end of the first hydraulic rods; a support rod is rotatably connected to the middle of the support frame; a geotextile body is fixedly connected to the side wall of the support rod; a pair of blocking rods are fixedly connected to the inner side wall of the support frame; and a set of first hydraulic rods... The contraction and extension of another set of first hydraulic rods can drive the support frame to adjust its tilt angle as a whole, so that the geotextile body can always be parallel to the inclined embankment surface when facing it. This ensures that the geotextile body fits tightly against the contact surface during laying, reducing wrinkles caused by the geotextile body not being parallel to the laying surface. In conjunction with the robotic arm, the support frame can be directly extended into the water, causing the geotextile body to rub against the laying surface, causing the support rods to rotate and unfold the geotextile. This reduces the need for professional underwater operations; the geotextile body can be laid simply by operating the excavator cab to control the swing angle and speed of the robotic arm, improving the safety of geotextile body laying.

[0007] Preferably, a second fixed seat is fixedly connected to the bottom end of the support frame; a rotating shaft is rotatably connected to the middle of the second fixed seat; multiple sets of friction rings are fixedly connected to the side wall of the rotating shaft; the friction rings are arranged in an array on the side wall of the rotating shaft; the geotextile body is slidably connected to the rotating shaft; the rotating shaft rotates synchronously with the traction of the geotextile body, always providing support from below, so that the geotextile body can maintain close contact with the ground even at the end of the laying, ensuring uniform and consistent laying quality, and the friction rings prevent the geotextile body from slipping during the laying process, making the laying speed uniform and controllable.

[0008] Preferably, a pair of support seats are fixedly connected to the top of the support frame; the support seats are located on both sides of the geotextile body; the bottom of the support seats is rotatably connected to a limit rod; the pair of limit rods apply constraints from both sides of the geotextile body, so that the geotextile body is always laid smoothly along the central axis of the support rod, reducing the deviation of the geotextile body at the top of the support rod, which would cause the final geotextile body to deviate from its laying position, and ensuring accurate laying position.

[0009] Preferably, a second hydraulic rod is fixedly connected to the top of the support frame; the second hydraulic rod is located at the center of the top of the support frame; a pressure plate is fixedly connected to the bottom of the second hydraulic rod; by activating the second hydraulic rod, the pressure plate is pressed down to lock the support rod, which can directly fix the geotextile body, reduce the rotation of the support rod during the adjustment of the geotextile body, and thus reduce the impact on the smoothness of the robotic arm adjustment.

[0010] Preferably, a drive motor is fixedly connected to the bottom end of the first fixed base; a support plate is fixedly connected to the output end of the drive motor; by starting the drive motor, the support frame can be rotated as a whole, and the laying direction of the geotextile body can be quickly adjusted by moving the main body of the excavator, ensuring that the geotextile body is laid continuously along the trajectory, reducing the limitations of straight laying of the geotextile body.

[0011] Preferably, a pair of retaining brackets are rotatably connected to the side wall of the support rod; bolts are threadedly connected to the side wall of the retaining brackets; by using the retaining brackets as intermediate isolation components, one end is rotatably connected to the support rod, and the other end is fixed to the side wall of the support frame by bolts, which can reduce the direct contact between the support rod and the support frame, thereby reducing the direct rotational friction between the support frame and the support rod, and also increasing the smoothness of the rotation of the support rod.

[0012] The advantages of this utility model are:

[0013] 1. The underwater geotextile laying machine described in this utility model, used in conjunction with a long-arm excavator, uses a set of first hydraulic rods retracting and another set of first hydraulic rods extending to adjust the tilt angle of the support frame as a whole. This ensures that the geotextile body remains parallel to the inclined embankment surface during laying, guaranteeing a tight fit between the geotextile body and the contact surface. This reduces wrinkles caused by the geotextile body not being parallel to the laying surface. In conjunction with the robotic arm, the support frame is directly extended into the water, causing friction between the geotextile body and the laying surface, which in turn causes the support rods to rotate and unfold the geotextile. This reduces the need for professional underwater operation; the geotextile body can be laid simply by controlling the swing angle and speed of the robotic arm from the excavator's cab, thus improving safety during geotextile laying.

[0014] 2. The underwater geotextile laying machine described in this utility model, used in conjunction with a long-arm excavator, uses a rotating shaft that rotates synchronously with the geotextile body to provide support from below. This ensures that the geotextile body remains in close contact with the ground even at the end of the laying process, guaranteeing uniform laying quality. In conjunction with the friction ring, the geotextile body is less prone to slipping during laying, and the laying speed is uniform and controllable. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, an underwater geotextile laying machine used in conjunction with a long-arm excavator includes a mechanical arm 1; a pair of fixing pins 11 are fixedly connected to the bottom end of the mechanical arm 1; a first fixing seat 12 is fixedly connected to the bottom end of the mechanical arm 1; the fixing pins 11 are connected to the first fixing seat 12; a support plate 13 is provided at the bottom end of the first fixing seat 12; a pair of first hydraulic rods 14 are hinged to the bottom end of the support plate 13; a support frame 15 is hinged to the bottom end of the first hydraulic rods 14; a support rod 16 is rotatably connected to the middle of the support frame 15; a geotextile body 17 is fixedly connected to the side wall of the support rod 16; the support... A pair of blocking rods 18 are fixed to the inner wall of the frame 15. During operation, the first fixed seat 12 is inserted into the bottom of the robotic arm 1, and then a pair of fixing pins 11 are inserted into the side wall of the robotic arm 1 to fix the first fixed seat 12 to the bottom of the robotic arm 1. Then, the support rod 16 can be placed in the groove in the middle of the support frame 15. Then, the blocking rods 18 are fixed to the inner wall of the support frame 15 to restrict the support rod 16 to the middle of the support frame 15. After the support rod 16 is fixed, the robotic arm 1 can be started to move the support frame 15 to the bottom of the water, so that the geotextile body 17 contacts the laying surface. Through the swing of the robotic arm 1, the geotextile body... Friction between the geotextile body 17 and the laying surface causes the support rod 16 to rotate as a whole. Under the continuous swinging of the robotic arm 1, the geotextile body 17 can be laid. When the geotextile body 17 needs to be laid on the embankment surface with a certain inclination angle, one set of first hydraulic rods 14 can be activated to retract, and another set of first hydraulic rods 14 can be activated to extend, so that the support frame 15 is tilted as a whole. When the geotextile body 17 is laid on the bottom of the embankment with an inclination angle, the geotextile body 17 can be laid parallel to the embankment surface. By retracting one set of first hydraulic rods 14 and extending the other set of first hydraulic rods 14, the tilt angle of the support frame 15 can be adjusted as a whole. This design ensures that the geotextile body 17 remains parallel to the inclined embankment surface when facing it, guaranteeing a tight fit between the geotextile body 17 and the contact surface during installation. This reduces wrinkles caused by the geotextile body 17 not being parallel to the installation surface. In conjunction with the robotic arm 1, the support frame 15 is directly extended into the water, causing the geotextile body 17 to rub against the installation surface. This allows the support rod 16 to rotate and unfold the geotextile, reducing the need for professional underwater operations. The geotextile body 17 can be laid simply by controlling the swing angle and speed of the robotic arm 1 from the excavator cab, thus improving the safety of the geotextile body 17 during installation.

[0025] like Figures 2 to 3As shown, a second fixed seat 2 is fixedly connected to the bottom end of the support frame 15; a rotating shaft 21 is rotatably connected to the middle of the second fixed seat 2; multiple sets of friction rings 22 are fixedly connected to the side wall of the rotating shaft 21; the friction rings 22 are arranged in an array on the side wall of the rotating shaft 21; the geotextile body 17 is slidably connected to the rotating shaft 21; during operation, the geotextile body 17 can be placed on one side of the rotating shaft 21, and the geotextile body 17 can be rotated to lay in contact with the support rod 16 of the laying surface. The rotating shaft 21 can rotate due to the traction of the geotextile body 17, so that the geotextile body 17... When the remaining area is insufficient, the rotating shaft 21 continuously supports the geotextile body 17, ensuring that the geotextile body 17 remains in continuous contact with the ground. Multiple sets of friction rings 22 can contact the geotextile body 17 to increase friction. As the rotating shaft 21 rotates synchronously with the traction of the geotextile body 17, it always provides support from below, ensuring that the geotextile body 17 remains in close contact with the ground even at the end of the laying process. This ensures uniform and consistent laying quality. In conjunction with the friction rings 22, the geotextile body 17 is less prone to slipping during the laying process, and the laying speed is uniform and controllable.

[0026] like Figures 2 to 3 As shown, a pair of support seats 3 are fixedly connected to the top of the support frame 15; the support seats 3 are located on both sides of the geotextile body 17; the bottom of the support seats 3 is rotatably connected to limit rods 31; during operation, when the support rod 16 rotates, the geotextile body 17 itself will tilt due to the rotation of the support rod 16. At this time, the pair of limit rods 31 can be rotatably connected to the geotextile body 17, forming a constraint on both sides of the geotextile body 17, so that the geotextile body 17 is stable in the middle of the support rod 16; by applying constraint from both sides of the geotextile body 17 through the pair of limit rods 31, the geotextile body 17 is always laid smoothly along the central axis of the support rod 16, reducing the deviation of the geotextile body 17 at the top of the support rod 16, which would cause the final position of the geotextile body 17 to deviate, and ensuring the accuracy of the laying position.

[0027] like Figure 3 and Figure 5 As shown, a second hydraulic rod 4 is fixedly connected to the top of the support frame 15; the second hydraulic rod 4 is located at the center of the top of the support frame 15; a pressure plate 41 is fixedly connected to the bottom of the second hydraulic rod 4; during operation, when the geotextile body 17 stops laying or wrinkles appear during laying, and the robotic arm 1 needs to be moved and adjusted as a whole, the second hydraulic rod 4 can be activated, and then the pressure plate 41 can apply pressure to the geotextile body 17 to lock the support rod 16, so that when the robotic arm 1 adjusts the geotextile body 17, the support rod 16 will not rotate, causing the laying to stack; by activating the second hydraulic rod 4 to drive the pressure plate 41 to press down and lock the support rod 16, the geotextile body 17 can be directly fixed, reducing the rotation of the support rod 16 during the adjustment of the geotextile body 17, thus affecting the smoothness of the adjustment of the robotic arm 1.

[0028] like Figure 2 As shown, a drive motor 5 is fixedly connected to the bottom end of the first fixed base 12; a support plate 13 is fixedly connected to the output end of the drive motor 5; during operation, the drive motor 5 can be started, and then the drive motor 5 can drive the support frame 15 to rotate as a whole, thereby rotating the laying direction of the geotextile body 17, so that the geotextile body 17 can be adjusted according to the actual situation when it is laid; by starting the drive motor 5, the support frame 15 can be rotated as a whole, and the laying direction of the geotextile body 17 can be quickly adjusted by reducing the movement of the excavator body, ensuring that the geotextile body 17 is laid continuously along the trajectory, and reducing the limitations of the straight laying of the geotextile body 17.

[0029] like Figures 3 to 4 As shown, a pair of retaining seats 6 are rotatably connected to the side wall of the support rod 16; bolts 61 are threadedly connected to the side wall of the retaining seats 6; during operation, the retaining seats 6 are fixed to the side wall of the support frame 15 by the bolts 61. When the support rod 16 rotates, because the retaining seats 6 are fixed to the side wall of the support frame 15, the support rod 16 will not directly rub against the support frame 15 during rotation; by using the retaining seats 6 as an intermediate isolation component, one end is rotatably connected to the support rod 16, and the other end is fixed to the side wall of the support frame 15 by the bolts 61, the direct contact between the support rod 16 and the support frame 15 can be reduced, thereby reducing the direct rotational friction between the support frame 15 and the support rod 16, and also increasing the smoothness of the rotation of the support rod 16.

[0030] Working principle: Insert the first fixed seat 12 into the bottom end of the robotic arm 1, then insert a pair of fixing pins 11 into the side wall of the robotic arm 1 to fix the first fixed seat 12 to the bottom end of the robotic arm 1. Then, place the support rod 16 into the groove in the middle of the support frame 15. Then, fix the blocking rod 18 to the inner side wall of the support frame 15 to restrict the support rod 16 in the middle of the support frame 15. After the support rod 16 is fixed, the robotic arm 1 can be started to move the support frame 15 to the bottom of the water, so that the geotextile body 17 comes into contact with the laying surface. Through the swing of the robotic arm 1, the geotextile body 17 and the laying surface can rub against each other, so that the support rod... The entire robotic arm 16 rotates, allowing the geotextile body 17 to be laid under the continuous swing of the entire robotic arm 1. When the geotextile body 17 needs to be laid on a dam surface with a certain inclination angle, one set of first hydraulic rods 14 can be activated to retract, and another set of first hydraulic rods 14 can be extended, causing the support frame 15 to present an inclination angle. When the geotextile body 17 is laid at the bottom of the dam with an inclination angle, the geotextile body 17 can be laid parallel to the dam surface. The geotextile body 17 can be placed on one side of the rotating shaft 21, and the geotextile body 17 can be placed in contact with the laying surface. When the support rod 16 is rotated for laying, the rotating shaft 21 can be adjusted due to the geotextile body 17. The traction and rotation during laying ensures that the geotextile body 17 remains supported by the rotating shaft 21 even when there is insufficient material remaining, maintaining continuous contact between the geotextile body 17 and the ground. Multiple friction rings 22 increase friction by contacting the geotextile body 17. When the support rod 16 rotates, the geotextile body 17 tilts due to the rotation. At this time, a pair of limiting rods 31 can be rotatably connected to the geotextile body 17, constraining both sides of the geotextile body 17 and stabilizing it in the middle of the support rod 16. When the geotextile body 17 stops laying or wrinkles appear during laying, requiring overall adjustment by the robotic arm 1, the first... The second hydraulic rod 4, and then the pressure plate 41 can apply pressure to the geotextile body 17, locking the support rod 16, so that when the entire robotic arm 1 is adjusting the geotextile body 17, the support rod 16 will not cause the laying to stack due to its rotation. The drive motor 5 can be started, and then the drive motor 5 can drive the support frame 15 to rotate, rotating the laying direction of the geotextile body 17, so that the geotextile body 17 can be adjusted according to the actual situation during laying. The entire card seat 6 is fixed to the side wall of the support frame 15 by bolts 61. When the support rod 16 rotates, because the card seat 6 is fixed to the side wall of the support frame 15, the support rod 16 will not directly rub against the support frame 15 to rotate.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
