Hydraulic upward turnover type gate

Abstract

The invention discloses a hydraulic upward turnover type gate comprising a gate, a hydraulic hoist, a hydraulic power unit and a control room, wherein the gate comprises three or more unit gates whichare arranged transversely, the odd unit gates are A type gates, the even unit gates are B type gates, each of the A type gates and the B type gates as well as an upper hoisting head of an oil cylinder of the hydraulic hoist are respectively hung on opposite sides of two box-type structural steel beams additionally arranged on the upstream and the downstream of an isolation strip between double-margined bridges, and the middle of each of the A type gates and the B type gates is respectively connected with each lower hoisting head of the oil cylinder of the hydraulic hoist through a trunnion; side seal rubbers at two sides of each B type gate are pressed on a gate leaf of the A type gate adjacent to the B type gate and bottom seal rubbers at the rear side of the bottom of each of the A typegates and the B type gates are pressed on the side of a sill so as to form a side and bottom sealing structure. The invention has the advantages of large-scale gate building, no influence to landscape, simple process, simple and convenient installation and lower cost.

Description

technical field [0001] The invention relates to a large-span gate, in particular to a hydraulic upturning gate. Background technique [0002] The long-span gate is different from the layout of conventional gates, and is often used in special environments with special functions, structures and effects. According to the rotation form, this type of gate can be roughly divided into upturn type, downturn type and rotary type. The following are some examples of completed projects. [0003] (1) The bottom shaft drives the flap gate (bottom flip type) [0004] The gate is used in the sluice gate of the Suzhou Creek Estuary and is of the downturn type. The gate is 100 meters wide and 9.76 meters high. The bottom shaft driven flap gate is a new type of gate that can realize the functions of "two-way water blocking and adjustable gate opening". The door leaf of the gate adopts a longitudinal cantilever beam structure, which is directly driven by the rotation of the bottom shaft op...

Hydraulic upturn scheme: complex structure and large investment

Conventional stacked girder gate: simple structure, small investment, only need to install gate maintenance platform and door crane track, etc., easy maintenance, sediment and dirt are not easy to silt up, but need to set gate pier, the door machine is large in size, and the landscape effect is poor; In addition, due to the door machine operation, there are disadvantages such as low degree of automation, many operating personnel, and long operating time.
