Problems solved by technology

Sometimes a turning handwheel is added to the hoist hoist, and the discharge gate can be opened by manually turning the reel, but the turning handwheel is only suitable for gates below 40 tons. The machine is powered only by electricity
When serious disasters or emergencies lead to power outages, if floods threaten the safety of water conservancy facilities, it is necessary to open the discharge gates to vent the floods, but the winch hoist driven only by electric energy cannot work, and the discharge gates cannot If it is turned on, there will be a serious danger
[0003]After searching, no manual opening device and method for sluice gate based on large tonnage jack have been found

Abstract

The invention discloses a sluice gate manual opening device and method based on a large-tonnage jack and relates to an opening technology of a sluice gate of hydraulic and hydro-power engineering. The structure of the device is mainly characterized in that a gate lifting hoist, the upper portion of a steel rope, a suspension hoisting mechanism and support beams are sequentially connected, the lower portion of the steel rope penetrates a middle channel of a gate base to be connected with the sluice gate through a movable pulley group, and the left ends and the right ends of a front support beam and a rear support beam, cushion blocks, the large-tonnage jack and the left side and the right side of the gate base are sequentially connected. The device is simple in structure and convenient to manufacture and operate. Manual opening of the sluice gate controlled by the gate lifting hoist can be achieved under the emergent condition, the large-tonnage jack is adopted, and over-40-tonnage sluice gate can be opened manually.

Description

technical field [0001] The invention relates to the technology for opening a discharge gate of a water conservancy and hydropower project, in particular to a device for manually opening a discharge gate based on a large-tonnage jack and a method thereof. Background technique [0002] In the current water conservancy and hydropower projects, because of its simple structure, easy manufacture, and convenient maintenance and repair, hoist hoist is widely used in the opening and closing of various discharge gates. It mainly uses electric energy to drive the reel to rotate, and through the retraction and release of the steel cable on the reel, it drives the gate to go up and down, so as to realize the opening and closing of the discharge gate. Sometimes a turning handwheel is added to the hoist hoist, and the discharge gate can be opened by manually turning the drum, but the turning handwheel is only suitable for gates below 40 tons. The machine is powered only by electricity. W...
