Lifting wharf

Abstract

The invention provides a lifting wharf. The lifting wharf comprises limiting piles provided with racks, and a wharf platform comprising a floating table and lifting mechanisms, wherein the lifting mechanisms comprise sleeves, walking mechanisms, walking stop mechanisms and floaters. The sleeves are arranged on the floating table and sleeve the limiting piles, and a first through hole and a secondthrough hole are formed in one side wall of each sleeve in a spaced mode. Each walking mechanism comprises a first walking mechanism and a second walking mechanism which are arranged on the corresponding sleeve in a spaced mode. The first walking mechanisms comprise first gears and first ratchet wheels coaxial with the first gears. The second walking mechanisms comprise second gears and second ratchet wheels coaxial with the second gears. The first gears and the second gears mesh with the racks, and pawls of the first ratchet wheels are opposite to pawls of the second ratchet wheels. First stop mechanisms can be engaged with the first ratchet wheels, and second stop mechanisms can be engaged with the second ratchet wheels. The floaters can move relative to the sleeves along with waves andcan make contact with first stop pins and second stop pins. According to the lifting wharf, self-adaptive water level adjustment of the wharf is realized through mechanical structures, the structure is simple, and stability is high.

Description

technical field [0001] The invention relates to the technical field of wharf equipment, in particular to a liftable wharf. Background technique [0002] There are many islands in our country, many of which have weak economic foundations due to poor infrastructure and inconvenient transportation. The development level of many islands is not high, and resources have not been effectively utilized. Especially in village-level islands, the transportation infrastructure is backward. Most of the islands have simple docks. Some village-level islands have not even built docks. Boats can only get on and off embankments, reefs or beaches. The water depth of the docks is seriously insufficient. Entering, or relying on small rafts to shuttle back and forth, it is quite inconvenient to park and travel. [0003] The island is located in a remote location, construction is inconvenient, and limited by geographical conditions, it is usually only suitable for the construction of small docks, ...

AI Technical Summary

Problems solved by technology

Small docks usually have a simple structure, poor structural stability and safety

Especially in the prior art, the wharf is mostly a fixed structure, which cannot be raised and lowered with the change of the tide level, and it is inconvenient for small ships on the island to go ashore. Therefore, building a small wharf that can adapt to the tide level is convenient for small ships to dock on the island. It is of great significance to promote the communication between the island and the outside world and promote the development and construction of the island area.
