Steel dam gate opened and closed by direct connection type opening and closing machine

Abstract

The invention discloses a steel dam gate opened and closed by a direct connection type opening and closing machine. The steel dam gate comprises a steel dam gate body which is fixedly mounted on a gate door bottom shaft, and further comprises an opening and closing machine room, wherein the gate door bottom shaft is fixed in a river way through a plurality of steel dam gate trunnions; the openingand closing machine room is arranged at the outer side of a river levee at the two ends of the gate bottom shaft; a power device is arranged in the opening and closing machine room; the power output shaft of the power device is connected to the two ends of the gate bottom shaft through a planetary reducer; the planetary reducer is inserted into the inner diameter of a circular tube of the gate bottom shaft; the planetary reducer is fixedly mounted on the end surface of the gate bottom shaft through a flange plate; and a gate horizontal supporting cushion and the steel dam gate trunnions are arranged in the river way in a rotation direction of the steel dam gate in parallel. The steel dam gate solves the defects that an existing steel dam gate hydraulic opening and closing machine is greatin floor space, hydraulic equipment is complex, and maintaining difficulty is great, is convenient for maintaining and prolonging the service life, and reduces production and maintenance cost better.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to a steel dam gate opened and closed by a direct-connected hoist. Background technique [0002] In the river gates and dams of urban water conservancy landscape projects, the retaining dam with the bottom shaft rotation is generally used. At present, the company adopts the self-developed patent No. CN206521737U, and the patent name is the water retaining equipment of the hydraulic structure of the hydraulic retaining dam. This equipment Although the directional rotation of the steel dam gate can be achieved, the construction and later maintenance are more difficult. The telescopic part that has been in the water for a long time needs to be treated with anti-corrosion and anti-rust treatment, which increases the difficulty of the process. Therefore, how to make the steel dam gate in the It is a technical problem to be solved by the present invention to have the ...
