Description

Technical Field

[0001] The present invention belongs to the field of dock health monitoring, and in particular relates to an automatic construction device for fixing underwater sensor cables and a construction process thereof. Background Art

[0002] The design life of the wharf is relatively long. During long-term use, due to the aging of components and other issues, the stress performance of the wharf also changes accordingly. At present, the full life health monitoring of structures such as wharfs has been proposed and increasingly implemented. The full life health monitoring of wharfs is to bury a corresponding number of sensors in each structural component of the wharf and analyze the measured sensor data to determine the stress performance of the whole and each component, providing a basis and guidance for the repair, maintenance and management decisions of the structure.

[0003] There are some construction difficulties in the installation process of the life-cycle health monitoring sensor. For example, some sensors are buried below the water surface and below the mud surface. The sensor test line needs to be laid along the pile from underwater. There is no facility for fixing the cable on the side wall of the pile that has been constructed, and most of the pile is underwater, which makes it very difficult to fix the sensor test line.

[0004] At present, the main method of fixing the test line is to use divers to construct underwater. Divers use clamps to surround the wire pipe and piles, dive into the corresponding position underwater, and lock the clamps to fix the cables. This construction method is not only costly and difficult, but also difficult to ensure the construction quality and inefficient. Summary of the invention

[0005] To solve the above problems, the present invention discloses an automatic construction device for fixing underwater sensor cables and a construction process thereof, which can replace the manual operation of divers and realize the fixation of underwater sensor cables along piles, thereby reducing the difficulty of installing health monitoring sensors and improving installation efficiency.

DETAILED DESCRIPTION

[0023] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] As shown in the figure, the automatic construction device for fixing underwater sensor cables described in the present invention includes two parts: an upper fixing frame and a construction module.

[0025] (1) Upper fixed frame: The upper fixed frame 8 is opened to form two semi-circular boxes connected by a rotating shaft 14. When in use, it is put on the round pile 1 and merged into a circular ring (the inner diameter is larger than the diameter of the round pile 1). The fixing card 13 on the rotating fixed frame is made to make the front ends of multiple fixing cards 13 press against the round pile to fix the upper fixed frame 8 to the round pile. The upper fixed frame includes 2-4 wire drums 2, and the wire drums 2 are wound with wires or cables 3 (the wires are used to provide power to the construction module, and the cables are used to realize the up and down movement of the construction module). Behind the wire drum 2 is a motor 10, which can rotate the wire drum to realize the release and reeling of the wire. At the same time, the upper fixed frame 8 contains a power supply and a controller 9. The power supply provides electricity, and the controller can control the movement of the construction module and the construction operation of the construction module.

[0026] (2) Construction module: The construction module 4 is also composed of two semi-circular boxes, which are opened and put on the round pile 1 to form a ring (the inner diameter is larger than the pile diameter). The construction module consists of the following parts:

[0027] 1. Throat clamp: The throat clamp 5 is a standardized product on the market. Before the installation, several throat clamps need to be loaded into the construction module from the upper part of the construction module, placed flat in the positioning cards 23 of the three conveyor belts, and surrounded by a circle that is adapted to the diameter of the construction module.

[0028] 2. Laryngeal hoop installation bin: The laryngeal hoop installation bin includes a laryngeal hoop joint positioning groove 16 and a conveyor belt 7. The laryngeal hoop joint positioning groove is a rectangular groove (from top to bottom) on the inner wall of the construction module. When the laryngeal hoop 5 is installed, the laryngeal hoop joint 18 needs to be inserted into the positioning groove 16. The positioning groove 16 can limit the lateral movement of the laryngeal hoop joint. The main body of the laryngeal hoop 5 is arranged in the positioning card 23. There are several groups of positioning cards 23, which are distributed on the side walls of the construction module and arranged longitudinally. The positioning cards 23 on the conveyor belt can support the laryngeal hoop 5 from multiple directions, limit the up and down movement of the laryngeal hoop 5, and can drive the laryngeal hoop 5 downward by rotating the motor 2 15.

[0029] 3. Laryngeal clamp locking construction device: The laryngeal clamp locking construction device 6 is located at the bottom of the construction module, including a hydraulic cylinder 20, a positioning screwdriver 17, an electric screwdriver 19 and a bottom support plate 21. The hydraulic cylinder 20 is located at the tail of the positioning screwdriver 17 and the electric screwdriver 19, and is used to realize the clamping and loosening of the laryngeal clamp joint 18. When the positioning screwdriver 17 and the electric screwdriver 19 are extended, the laryngeal clamp joint 18 can be clamped from the left and right sides, wherein the electric screwdriver 19 can rotate the screw of the laryngeal clamp joint, thereby locking the laryngeal clamp (the rear ends of the positioning screwdriver 17 and the electric screwdriver 19 are connected to the hydraulic cylinder 20, and the electric screwdriver 19 is internally connected to a micro motor. There are standard products on the market for the electric screwdriver 19, and the forward and backward movement is carried out by the hydraulic cylinder at the rear end. These two parts are the integration of two separate parts and are also controlled separately). The bottom support plate 21 is located at the bottom of the laryngeal clamp joint 18, and is used to support the laryngeal clamp joint to prevent it from falling. When the locking construction of a throat clamp is completed, the bottom support plate 21 is retracted into the side wall of the construction module through the gear 22.

[0030] The overall construction process of the device: First, open the upper fixing frame 8 and the construction module 4, put them on the round pile 1 to be constructed and close them. Turn the fixing card 13 on the upper fixing frame so that the fixing card 13 is against the pile. At this time, the upper fixing frame 8 is fixed to the pile 1, and the construction module 4 is connected to the upper fixing frame through the suspension cable 3, and the construction module 4 is suspended. Install several hose clamps 5 into the construction module 4 from the top of the construction module. When construction starts, control the wire drum 2 to rotate and release the wire through the remote control, so that the construction module descends by gravity until it reaches the required lowest position. After reaching the position, the gear 22 rotates to drive the bottom support plate to extend to the bottom of the throat clamp joint 18, which is used to support the throat clamp joint to prevent it from falling; the positioning screwdriver 17 and the electric screwdriver 19 extend at the same time to clamp the throat clamp joint 18, and the electric screwdriver 19 rotates, and the throat clamp 5 is slowly tightened, the diameter becomes smaller and it escapes from the positioning card 23 of the conveyor belt (the positioning card 23 is a flat plate, in the diameter direction, the positioning card has no constraints on the throat clamp, and there is nothing upturned to hook the throat clamp, so the throat clamp will automatically escape when it is tightened). When the throat clamp 5 is locked, the screwdriver is retracted and the bottom support plate 21 is retracted. At this time, the locked throat clamp will not be stuck by the entire device. After completion, the control reel 2 is used to reel in the wire to raise the construction module 4 to the next position, extend the bottom support plate 21, control the conveyor belt 7 to rotate downward one grid, and continue construction.

[0031] The underwater sensor cable is fixed by this device. Before installing this device, the underwater cable is passed through this device and fixed together with this device at the top.
