Gate hoist

Abstract

The invention relates to a gate control device that could quick show down the gate, comprising a base, a controlling device, a drive motor, a driving device and a box body, the driving axis of the driving device is connected arranged inside the screw of the box body via a driving gear, the screw is provided with an internal feed screw, the bottom of the feed screw is connected with the gate, comprising a retaining clutch, a speed-limiting device and a cushion cylinder, the motor axis is connected with the driving axis via the retaining clutch, the central part of the rotation axis is providedwith a speed-limiting device fixed connected with the box body, the top end of the feed screw is connected with a cushion cylinder. When The invention is power off, the magnetic brake is released, andthe gate drops and shuts down by the weight. When the gate automatically drops, the drive motor will be reversely drove by the driving device, to prevent the magnetic electricity generated by the reverse rotation of the motor from damaging the drive motor, to control the rotation speed of the driving axis, to prevent the direct burst of the weight, to effectively protect the gate and the base, and to mutually prolong the durability of the cushion cylinder.

Description

technical field [0001] The invention relates to a water conservancy gate hoisting machine, in particular to a gate hoist capable of quickly closing a gate. Background technique [0002] At present, the gate hoist is widely used in various water supply and drainage projects, hydropower, and water conservancy projects. When the gate hoist closes the gate, it generally still needs to be driven by power, which takes a long time to close, and also needs to be driven by a motor, which consumes electricity. In the event of a power outage, sudden flooding, etc., the gate cannot be closed in time, which will cause a large flow of water to overflow. Contents of the invention [0003] The invention provides a gate hoist that can quickly close the gate by relying on the self-weight of the gate, and will not cause impact damage to the gate due to high-speed falling when closing. [0004] The technical scheme of the present invention is: composed of machine base, control device, drive ...
