Floating type bollard

Abstract

The invention discloses a floating type bollard which comprises a floating cylinder, a support frame, two bollard bodies and six guide roller systems. The support frame is fixed on the upper portion of the support frame. The two bollard bodies are respectively disposed at the top of the floating cylinder and at the top of the support frame. The six guide roller systems are respectively disposed on two sides of the upper portion of the floating cylinder, on two sides of the bottom of the floating cylinder and on two sides of the top of the support frame. Each guide roller system comprises a transverse roller and a longitudinal roller which are stacked from top to bottom. The rolling shaft of the transverse roller is vertical to that of the longitudinal roller. A floating base is vertically disposed on a lock wall. The guide roller systems are disposed in the floating base. The floating type bollard has the advantages that the floating cylinder can move up and down automatically along with water level change, relative fixation between the bollard and a ship tied to the bollard is guaranteed, and operation convenience is brought to sailors; the two-deck bollard can satisfy the mooring requirements of ships of different tonners, empty ships and loaded ships, construction cost of fixed bollards can be reduced, times for tying and untying mooring lines due to water level change of a lock chamber during ship lockage are reduced, and lockage safety is increased.

Description

technical field [0001] The invention relates to a bollard and belongs to the technical field of waterway gate devices. Background technique [0002] With the development of society, the water transportation industry has become more and more prosperous, and the number of ships passing through the locks has also increased by leaps and bounds, and the problem of berthing ships in the lock chamber has gradually been exposed. The traditional bollards are fixed. During the operation of the lock, the water level in the lock chamber changes periodically, and the water head difference ranges from a few meters to tens or tens of meters. Setting too many bollards not only increases the project cost, but also It often cannot meet the requirements for convenient mooring, and there is also a safety risk. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a buoy that can be easily moored by the crew w...
