Asymptotic hydraulic engineering gate lifting device

Abstract

The invention relates to the technical field of hydraulic engineering gates, in particular to an asymptotic hydraulic engineering gate lifting device which comprises a gate seat, a gate, a gate lifting device and small gates. The gate is clamped in sliding grooves formed in the inner sides of supporting columns on the two sides of the gate seat, a cross beam connected between the upper ends of thesupporting columns on the two sides of the gate seat is provided with the gate lifting device, and small gate ports formed in the surface of the gate are provided with the small gates. The device hasthe beneficial effects that a motor is controlled to work, an output shaft end of the motor is in transmission connection with a screw rod through a transmission mechanism in a transmission box, thescrew rod and the gate connected with the lower end of the screw rod are lifted under the connection relationship with the screw rod, manual rotation is not needed, and labor saving and convenience are realized; telescopic rods of hydraulic cylinders are independently controlled to contract, and the small gates closing the small gate ports are turned upwards, so that each small gate port can be independently controlled to discharge, and the whole gate does not need to be lifted.

Description

technical field [0001] The invention relates to the technical field of water conservancy project gates, in particular to an asymptotic lifting device for water conservancy project gates. Background technique [0002] The control facilities used to close and release water channels in water conservancy buildings are an important part of water conservancy buildings. The traditional gate is generally opened by a wheel, and the user needs to turn the wheel by hand to open the gate through a screw rod. It is inconvenient and laborious to open and close the gate; when it is necessary to control the flow of a small flow, the traditional The gate needs to lift the entire gate, and frequent lifting and lowering of the gate will easily cause wear and tear on the connecting structure of the gate, thus affecting the sealing effect of the waterway. Contents of the invention [0003] The purpose of the present invention is to provide a gradual lifting device for hydraulic engineering ga...
