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 which are 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 type gates 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 present invention involves a large span gate, especially the hydraulic flip slice. Background technique [0002] The large span gate is different from the layout of the conventional gate and is often used in a special environment. It has special functions, structures and effects.Classified in the form of rotation, such gates can be roughly divided into ups and divesty, down flip -type peaceful rotation.Here are several instances that have been built. [0003] (1) The bottom shaft driver flip gate (down flip) [0004] The gate is applied to the exit of the Suzhou River, which is flipped.The gate is 100 meters wide and 9.76 meters high.The bottom shaft driving flip gate is a new type of gate that can realize functions such as "two -way water blocking and openness".The gate of the gate is a longitudinal cantilever beam structure, which is directly driven by the hydraulic opening and closed operation of the bottom shaft. Because the width of the gate of the...

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.
