Description

Technical Field

[0001] The utility model relates to the technical field of floating bridges on water, in particular to an automatically retractable and openable floating bridge. Background Art

[0002] The floating bridge is built by several floating boards with good versatility and interchangeability. According to the different needs of customers, special equipment is configured to build various floating bridges, such as landscape floating bridges, traffic floating bridges, military floating bridges, etc. It is mainly composed of the main floating bridge and the shore-connected part, and is widely used in sightseeing, tourism, leisure and other fields. The main fixing methods of floating bridges are poles, ropes, anchoring, piling and mixed use.

[0003] For example, application number 202220506593.9 discloses a floating bridge that is easy to splice, including a floating bridge board body, a connecting structure, a rotating rod, a first gear, a second gear, a threaded rod, a threaded groove, a driving rod, a protective structure and a sealing plug. The beneficial effect of the utility model is: by rotating the driving rod, the rotating rod is driven to rotate, and then the two first gears, the two second gears and the two threaded rods are driven to rotate. The rotation of the threaded rod will be threadedly connected with the threaded groove, so that the two floating bridge board bodies are close to each other and conflict with each other, and then they can be tightly connected, which is convenient for the splicing of the floating bridge board body. Then, the driving rod is pushed into the interior of the floating bridge board body, and the sealing plug is covered to protect the driving rod, so as to effectively protect the driving assembly and avoid water corrosion. Then, the protective structure is used to strengthen the connection stability between the two floating bridge board bodies, and at the same time, the sealing plug and the driving rod are protected, which greatly improves the protection stability of the driving assembly, facilitates the subsequent disassembly and installation work, and is easy to use.

[0004] Although this prior art solves the problem that the operation of the traditional floating bridge is cumbersome, time-consuming and labor-intensive when splicing two floating boards, after the multiple floating boards are spliced ​​to form a complete bridge body, they will block the river or lake surface, making it impossible for ships to pass smoothly, unless they are manually moved away to form an opening for a very long time, which is very inconvenient. In this regard, we propose an automatically retractable and openable floating bridge. Utility Model Content

[0026] Example

[0027] 4 , the present embodiment provides an automatically retractable and retractable floating bridge, comprising a main floating plate 1, a first connecting plate 2, a second connecting plate 3 and an adjusting mechanism 4, wherein the first connecting plate 2 is rotatably connected to the left side of the main floating plate 1, the second connecting plate 3 is rotatably connected to the right side of the main floating plate 1, and the front and rear sides of the left end of the first connecting plate 2 are symmetrically installed with connecting blocks 201, the front and rear sides of the right end of the second connecting plate 3 are symmetrically provided with connecting grooves 301 adapted to the two connecting blocks 201, the middle parts of the two connecting blocks 201 are provided with through grooves 201a, the middle parts of the two connecting grooves 301 are provided with slots 301a, the front and rear sides of the right end of the second connecting plate 3 are symmetrically provided with moving grooves 302, the interiors of the two moving grooves 302 are slidably connected with moving plates 303, the inner sides of the two moving plates 303 are transmission-connected with the adjusting assembly 4, the opposite back sides of the outer sides of the two moving plates 303 are fixedly installed with latches 304, and the adjusting assembly 4 can drive the two moving plates 303 to achieve horizontal movement. The two movable plates 303 can drive the two latches 304 to move horizontally back and forth because the diameter of the two through grooves 201a is the same as the diameter of the two slots 301a, and the diameter of the two latches 304 is slightly smaller than the diameter of the two through grooves 201a. When the two main floating plates 1 need to be spliced, the staff only needs to put the two connecting blocks 201 on the first connecting plate 2 at the left end of one of the main floating plates 1 into the two connecting grooves 301 of the second connecting plate 3 on the other main floating plate 1, and align the through grooves 201a and the slots 301a of the first connecting plate 201 and the second connecting plate 301. Then, the two movable plates 303 are driven to move horizontally back to back through the adjustment component 4. The two movable plates 303 can drive the two latches 304 to move horizontally back to back. When the two latches 304 are fully inserted into the two slots 301a, the limiting fixation of the first connecting plate 2 and the second connecting plate 3 is completed, thereby realizing the splicing of the two main floating plates 1 (see Figure 2 of the specification). Figure 1 That is, the state after the two main floating plates 1 are spliced ​​together).

[0028] Specifically, the adjustment component 4 includes a knob 401 arranged at the front end of the outside of the second connecting plate 3, the rear end of the knob 401 is fixedly connected to the rotating shaft 402, the rear end of the rotating shaft 402 passes through the outer wall of the second connecting plate 3 and extends to the inside thereof and is fixedly connected to the first threaded rod 403, the rear end of the first threaded rod 403 is fixedly connected to the rotating rod 404, the rear end of the rotating rod 404 is fixedly connected to the second threaded rod 405, the outer surfaces of the first threaded rod 403 and the second threaded rod 405 are both threadedly connected to sliders 406, and the right ends of the two sliders 406 are respectively fixedly connected to the two movable plates 303, and the external thread rotation directions of the first threaded rod 403 and the second threaded rod 405 are set in opposite directions.

[0029] In the adjustment component 4, the knob 401 is arranged on the outside of the second connecting plate 3, which is convenient for the staff to use. When the staff rotates the knob 401 in the forward direction, the knob 401 can drive the first threaded rod 403 to rotate through the rotating shaft 402, and the first threaded rod 403 can drive the second threaded rod 405 to rotate through the rotating rod 404. Because the external threads of the first threaded rod 403 and the second threaded rod 405 are arranged in opposite directions, the two sliders 406 threadedly connected to the first threaded rod 403 and the second threaded rod 405 can move horizontally in opposite directions, and the two sliders 406 can drive the two movable plates 303 and the latch 304 to move horizontally in opposite directions. Similarly, when the staff rotates the knob 401 in the reverse direction, the two sliders 406 can drive the two movable plates 303 and the latch 304 to move relative horizontally, thereby realizing the function of adjusting the horizontal positions of the two movable plates 303 and the latch 304.

[0030] Furthermore, limiting grooves 305 are symmetrically provided inside the second connecting plate 3 and on the front and rear sides of the movable groove 302. The limiting plates 306 are slidably connected inside the two limiting grooves 305. The opposite surfaces of the two limiting plates 306 are fixedly connected with sealing plates 307, and the opposite ends of the two sealing plates 307 respectively penetrate the inner walls of the two limiting grooves 305 and extend into the movable groove 302 and are respectively fixedly connected to the front and rear sides of the movable plate 303. In the above structure, sealing plates 307 are provided on the front and rear sides of the movable plate 303, and parts of the two sealing plates 307 are slidably connected in the movable groove 302 and close to the outer end of the second connecting plate 3. This enables the two sealing plates 307 to seal the opening of the movable groove 302 when the movable plate 303 moves horizontally forward or backward, thereby preventing water from entering the interior of the second connecting plate 3 through the movable groove 302, causing the internal parts to be corroded by the water flow, reducing their service life, and achieving a good protective effect.

[0031] Preferably, the rotating shaft 402 and the rotating rod 404 are rotatably connected to the inner wall of the second connecting plate 3 through the set bearing 407. The set bearing 407 can limit and fix the rotating shaft 402 and the rotating rod 404. At the same time, due to the characteristics of the bearing 407 itself, the rotating shaft 402 and the rotating rod 404 can rotate more smoothly to avoid jamming and affect the normal operation of the adjustment component 4.

[0032] In summary, when a ship needs to cross the floating bridge, the staff rotates the knob 401 in the opposite direction, and the knob 401 can drive the first threaded rod 403 and the second threaded rod 405 to rotate through the rotating shaft 402 and the rotating rod 404. The first threaded rod 403 and the second threaded rod 405 can drive the two sliders 406 to move horizontally relative to each other, and the two sliders 406 can drive the two moving plates 303 and the latch 304 to move horizontally relative to each other. When the two latches 304 are completely moved out of the two through slots 201a, the first connecting plate 2 and the second connecting plate 3 are released. 3, at this time, the staff flips the second connecting plate 2 on the left side onto the main floating plate 1 on the left side, and flips the first connecting plate 2 on the right side onto the main floating plate 1 on the right side, so that an opening is formed between the two main floating plates 1, so that the ship can pass smoothly. If the width of the opening is narrow and the ship still cannot pass, the staff can continue to flip, flip the left main floating plate 1 to the left, and flip the right main floating plate 1 to the right, so that the width of the opening between the two main floating plates 1 can continue to expand until it is large enough for the ship to pass.
