Description

Technical Field

[0001] The invention relates to the technical field of dock doors, in particular to a pontoon-type dock door. Background Art

[0002] A dock is a dock-type building used for ship repair and construction. It controls the water level by filling or draining water to enable ships to enter and exit and perform dry bottom operations. It is mainly divided into three categories: dry dock, water-filled dock and floating dock. The dock door is a key structure for closing the dock entrance, used to isolate the internal and external waters and withstand water pressure. Common types include pontoon type, lying type, horizontal pulling type, etc. The pontoon type dock door adopts a box-shaped design, which controls the buoyancy and sinking by filling or draining water to achieve opening and closing. It has bidirectional pressure-bearing capacity and is equipped with a rubber waterstop device. It is suitable for frequent opening and closing scenarios.

[0003] The above-mentioned device does not have a structure for assisting the dock door to sink and close the dock opening and assisting the dock door to be fixed when in use. As a result, when the existing dock door is in use, since the pontoon-type dock door floats on the water surface when closing the dock opening, and the floating and sinking are controlled by water injection or drainage to achieve opening and closing, it is difficult to accurately control the sinking position during the lifting process, and it takes a lot of time to accurately position it. In addition, when the dock door is closed, if a more severe harsh environment occurs, the dock door will have a certain possibility of loosening, which will cause a more serious accident. Based on the deficiencies in the existing technology, the present invention designs a pontoon-type dock door. Summary of the invention

[0033] By providing a first push plate 303 and an outward-expanding clamp block 305, auxiliary fixation of the dock door body 2 is facilitated; by providing a sealing gasket 304, the sealing between the first push plate 303 and the side groove 301 is facilitated to improve the sealing between the first push plate 303 and the side groove 301 to prevent a large amount of water from entering the inner groove 302; by providing a threaded shaft 306, a threaded slider 307, a first push arm 308, a hinge block 309, a reducer 310 and a driving motor 311, the first push plate 303 and the outward-expanding clamp block 305 are driven to move inward or outward to achieve clamping, fixing or releasing the dock door body 2.

[0034] Working principle: when a pontoon dock door is used, in the initial state, first, the dock entrance 101 is set at the exit of the dock body 1, and the movable rail 102 fixedly connected to the dock body 1 is installed with a crane 103, and the dock body 1 and the dock door body 2 set in the dock entrance 101 are installed with water inlet and outlet pipes 201 and guardrails 202, so as to isolate the water area for building or repairing ships, and the first push plate 303 and the outward expansion clamping block 305 installed in the side groove 301 and the inner groove 302 opened on both sides of the dock door body 2 are connected to the threaded shaft 306 through the hinge block 309 and the first push arm 308, and the threaded shaft 306 is connected to the reducer 310 and the driving machine 310. 1 is connected to facilitate control of the first push plate 303 and the outward expansion clamping block 305 sliding inside the side groove 301 and the inner groove 302, thereby assisting in fixing the dock door body 2, and the lift 403, the bracket 404 and the clamping plate 405 are installed in the lifting groove 401 and the bottom groove 402 opened below the dock door body 2, and the clamping plate 405 is connected to the bracket 404 through the limit rod 406 and the push-pull rod 409, while the inner end of the push-pull rod 409 is connected to the second push arm 410, the connecting seat 411 and the linkage shaft 413, and the linkage shaft 413 is connected to the telescopic cylinder 415 through the second push plate 414, so as to control the opening and closing of the clamping plates 405 on both sides of the bracket 404;

[0035] When it is necessary to assist the dock door body 2 in positioning and sinking, first, when the dock door body 2 needs to close the dock body 1, the onshore staff uses the steel cable and operating equipment to pull the dock door body 2 to move into the dock body 1. After the dock door body 2 moves above the bracket 404, the elevator 403 extends out to push the bracket 404 to move upward. At the same time, the front end of the telescopic cylinder 415 extends out to push the linkage shaft 413 to move to one side through the second push plate 414, and uses the moving linkage shaft 413 to pull the connecting seat 411 to move accordingly. Then, the moving connecting seat 411 is used to slowly flatten the second push arm 410 and push the push-pull rod 409 to expand outward. The expanded push-pull rod 409 pushes the clamping plate 405 outward between the limit rod 406 and the limit The dock door body 2 is clamped and limited to the position just above the bracket 404. At this time, the dock door body 2 can be filled with water into the ballast water tank and start to sink with the assistance of the elevator 403. The device is convenient for assisting the dock door body 2 in positioning and sinking.

[0036] When it is necessary to assist in limiting the dock door body 2, first wait until the dock door body 2 completes closing the dock body 1, then the driving motor 311 controls the reducer 310 to drive the threaded shaft 306 to rotate forward, and the threaded shaft 306 that rotates forward uses the surface thread to drive the two sets of threaded sliders 307 at both ends to move toward each other to flatten the first push arm 308, and the flattened first push arm 308 pushes out the hinge block 309, the first push plate 303 and the outward expansion clamp block 305, so that the outward expansion clamp block 305 contacts the dock door body 2 and generates a certain clamping pressure to fix it. This device is convenient for assisting in limiting the dock door body 2.
