Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a device for deploying and retrieving an unmanned boat for bridge detection. Background Art

[0002] When carrying out bridge detection operations, the application of unmanned boats is becoming more and more widespread. During the detection operation, the unmanned boat is placed on the water surface, and the bridge can be detected through remote control. When deploying the unmanned boat, usually, the staff carry the hull to the river bank and manually place the unmanned boat on the water surface to complete the deployment of the unmanned boat. In engineering, revetment structures are set on both banks of the river at many bridges, resulting in a large distance between the reachable position of people and the water surface. At the same time, there are other situations such as impassable due to river bank silt, which causes the detection personnel unable to approach the river bank, and thus unable to place the unmanned boat on the water surface for deployment. Currently, there is no specially developed device for deploying and retrieving an unmanned boat for bridge detection operations. In the face of the above scenarios where it is impossible to approach the river bank, the unmanned boat cannot be deployed to carry out bridge detection operations. The utility model designs a device for deploying and retrieving an unmanned boat suitable for the scenario of bridge detection operations. By using this device on the bridge deck of the bridge, the unmanned boat can be conveniently deployed on the water surface for detection operations, and after the operation is completed, the unmanned boat can be conveniently retrieved, realizing that the deployment and retrieval of the unmanned boat are not restricted by the river bank environment.

Detailed implementation mode

[0019] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] As Figures 1 to 4 shown, a mooring cable retracting and releasing device for a bridge inspection unmanned ship of the present utility model includes a box body 1 fixedly connected to a bracket 12. A transmission gear 3 is arranged in the box body 1. The transmission gear 3 is connected to a driven gear 6 through a transmission shaft 5. A mooring cable roller 7 is fixedly connected to the right side of the driven gear 6. A mooring cable 8 is wound around the mooring cable roller 7. One end of the mooring cable 8 extends out of the box body 1 through a reserved hole on the mooring cable roller 7 and is connected to a DC power supply 14. The other end of the mooring cable 8 is connected to an electromagnet 9. The electromagnet 9 is connected to an iron metal block 10 on the unmanned ship. The transmission shaft 5 drives the driven gear 6 and the mooring cable roller 7 to rotate together, so as to realize the up and down retracting and releasing of the mooring cable 8. The end of the mooring cable 8 enters the inside of the mooring cable roller 7 through the reserved hole of the mooring cable roller 7, passes through the mooring cable roller 7 and then passes out of the box body and is connected to the DC power supply 14, so as to ensure that the mooring cable 8 does not get entangled when the mooring cable roller 7 rotates. After the power switch 141 on the DC power supply 14 is turned on, the electromagnet 9 at the front end of the mooring cable 8 generates magnetic force (the prior art will not be elaborated), and adsorbs the iron metal block 10 fixed on the bridge inspection unmanned ship. After the power switch 141 is turned off, the electromagnet 9 demagnetizes and disconnects from the iron metal block 10, completing the release of the bridge inspection unmanned ship. It is convenient and efficient to use and has good practicability.

[0021] Furthermore, the outer surface of the mooring cable 8 of the present utility model adopts a polyethylene insulating material, and the internal conductor is a tinned copper core, and the strength meets the retracting and releasing tension of the bridge inspection unmanned ship.

[0022] Furthermore, a rotating handle 2 is connected to the outside of the transmission gear 3. By rotating the rotating handle 2, the unmanned ship can be placed on the water surface to avoid the phenomenon that the mooring cable gets explosively wound and knotted due to too fast wire release.

[0023] Furthermore, a counterweight base 13 is connected to the bottom of the bracket 12, and the middle upper part of the bracket 12 is connected to the bottom surface of the box body 1 through a support rod 11. The support rod 11 can support the box body 1, and the counterweight base 13 can ensure the structural stability and prevent tipping, and has good practicability.

[0024] Further, a locking mechanism 4 is provided below the transmission gear 3. The locking mechanism 4 includes a support block 15. A hollow connecting rod 47 is installed in the support block 15. A fixed block 41 is provided in the connecting rod 47. The bottom end of the fixed block 41 is fixedly connected to the box body 1. A protruding stop block 45 is fixedly connected to the fixed block 41. The right end of the fixed block 41 is connected to a limit block 43 through a spring 44. A chute 42 is formed on the surface of the connecting rod 47. The right end of the connecting rod 47 is connected to the limit block 43, and the left end of the connecting rod 47 is connected to a handle 46. To ensure the stability of the bridge inspection unmanned ship during the lowering and recovery processes, a locking device 4 is provided at the transmission gear 3. When taking braking measures, pull the handle 46 outwards to drive the connecting rod 47 and the limit block 43 to move outwards, and the spring 44 is compressed. When the protruding stop block 45 is located at the bottom of the L-shaped chute 42 and cannot be pulled, rotate the handle 46, and the protruding stop block 45 can be locked with the connecting rod 47. At this time, the transmission gear 3 is blocked by the limit block 43 to complete braking; conversely, the transmission gear 3 is released; it is convenient and efficient to use and has good practicability.

[0025] Further, the chute 42 is in an "L" shape. The "L"-shaped chute 42 facilitates locking the transmission gear 3. When needed, just rotate the connecting rod 47 and press the protruding stop block 45 against the short side of the chute 42.

[0026] Further, the position of the protruding stop block 45 is adapted to the position of the chute 42. The protruding stop block 45 can slide in the chute 42 according to the reciprocating pulling and rebounding of the connecting rod 47.

[0027] Further, the distance between the bottom surface of the support block 15 and the axis of the connecting rod 47 is greater than the distance between the highest point of the limit block 43 and the axis of the connecting rod 47. When it is necessary to lock the transmission gear 3, just pull the handle 46 to drive the connecting rod 47 and the limit block 43 to rotate. For smooth rotation, the distance between the bottom surface of the support block 15 and the axis of the connecting rod 47 is set to be greater than the distance between the highest point of the limit block 43 and the axis of the connecting rod 47.
