[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: an approach bridge structure for a barge, including a barge main body 1, an approach bridge main body 2 arranged above the barge main body 1, a limiting mechanism 3 is arranged in the middle of one end of the approach bridge main body 2 away from the barge main body 1, and elastic mechanisms 4 are arranged on both sides of one end of the limiting mechanism 3 away from the barge main body 1;

[0023] One end of the approach bridge main body 2 away from the floating dock main body 1 has a first groove 5 opened on its lower surface in the middle. The limiting mechanism 3 includes a first push plate 301 arranged inside the first groove 5. The upper end of the first push plate 301 is fixedly connected with a first spring 302. The connection mode of the first spring 302 and the approach bridge main body 2 is fixed connection. A guiding groove 303 is arranged inside the first push plate 301. The external structure of the guiding groove 303 is an inclined straight line, and the cooperation mode of the guiding groove 303 and the guiding rod 304 is clearance fit, so that when the first push plate 301 moves up and down, it can drive the guiding rod 304 to move horizontally. A guiding rod 304 is arranged inside the guiding groove 303. One end of the guiding rod 304 is fixedly connected with a first push rod 305. The two sides of the first groove 5 communicate with a second groove 306. A limiting rod 307 is arranged inside the second groove 306. One end of the limiting rod 307 close to the central axis of the first push rod 305 has an external structure of a cuboid, and one end surface of the limiting rod 307 away from the central axis of the first push rod 305 is an inclined surface, so that when the limiting rod 307 is pushed, it can move downward along the edge of the limiting rod 307, and the limiting rod 307 will not rotate when moving inside the second groove 306. The connection mode of the limiting rod 307 and the first push rod 305 is fixed connection. One side of the first groove 5 away from the floating dock main body 1 communicates with a sliding groove 308. A sliding block 309 is arranged inside the sliding groove 308. The connection mode of the sliding block 309 and the first push plate 301 is fixed connection. The width of the sliding block 309 at the end close to the floating dock main body 1 is greater than the width of the sliding block 309 at the end away from the floating dock main body 1, and the outer side surface of the sliding block 309 fits with the outer side surface of the sliding block 309, and the vertical height of the sliding block 309 is the same as the vertical height of the sliding groove 308, so that the sliding block 309 will not shake when moving inside the sliding groove 308.

[0024] One end of the second groove 306 away from the central axis of the first push plate 301 communicates with a third groove 6. The elastic mechanism 4 includes a second spring 401 fixedly connected inside the third groove 6. A support plate 402 is fixedly connected below the second spring 401. The external structure of the support plate 402 is a cuboid, and the outer side surface of the support plate 402 fits with the inner side surface of the third groove 6, so that the support plate 402 will not rotate when moving inside the third groove 6. A rubber pad 403 is fixedly connected to the lower end of the support plate 402. A limiting groove 404 is arranged inside the support plate 402. There are multiple limiting grooves 404, and the cooperation mode of the limiting groove 404 and the limiting rod 307 is clearance fit, so that the limiting rod 307 can move into the inside of the limiting groove 404. The length of the support plate 402 when the second spring 401 is in the natural state is greater than the length of the first push plate 301 when the first spring 302 is in the natural state, so that the support plate 402 will contact the ground earlier than the first push plate 301.

[0025] When the main body 2 of the approach bridge needs to be placed, rotate the main body 2 of the approach bridge so that the support plate 402 contacts the ground with the rubber pad 403 first. Under the action of the gravity of the main body 2 of the approach bridge, the support plate 402 and the second spring 401 are compressed, so that the limiting groove 404 is aligned with the second groove 306. At this time, the rubber pad 403 has already contacted the ground. Continue to place the main body 2 of the approach bridge. Since the length of the support plate 402 in the natural state of the second spring 401 is greater than the length of the first push plate 301 in the natural state of the first spring 302, the back of the first push plate 301 is pushed. Since the appearance structure of the guiding groove 303 is an inclined straight line, and the matching mode of the guiding groove 303 and the guiding rod 304 is clearance fit, the guiding rod 304, the first push rod 305 and the limiting rod 307 move along the track of the second groove 306 to both sides. Since one end face of the limiting rod 307 far from the central axis of the first push rod 305 is an inclined surface, the limiting rod 307 pushes the support plate 402 to move after contacting the edge of the limiting groove 404, completing the limitation of the support plate 402, making the placement of the main body 2 of the approach bridge more stable and reducing the risk of people falling.
