Description

STRUCTURE FOR CONNECTING OPENING AND SHUTTING LEVER OF SLUICE WITH A SHAFT}

The present invention relates to a combined structure of a hydro gate lever and a drive shaft of a hydro door winch, and more specifically, a hydro gate of a hydro gate winch that can secure a safety enough to open and close a gate by a designated work tool. It relates to a coupling structure of the opening and closing lever and the drive shaft.

In general, the hydro-winder used to open and close the gate is divided into a spindle method and a pin rack method.

In the spindle method, the circular handle is rotated to rotate the lower screw shaft, so that the water gate fixed to the screw shaft is moved up and down to open and close, which is caused by the rotation of the screw shaft. It takes a long time and becomes inconvenient to operate by the rotation operation of the handle, and furthermore, if foreign matters are caught in the screw shaft, it is difficult to raise and lower the operation thereof, so that frequent management checks and maintenance work are required.

On the other hand, the pin rack method is a lever-type handle operation by rotating the rotary shaft in which the pinion gear is arranged to move the rack bar up and down by the pinion gear, by raising and lowering the water lock fixed thereto, which is the rack bar The gate is raised and lowered by the lifting and lowering operation of the gate, which reduces the opening and closing operation time of the gate compared to the spindle method using the screw shaft, and makes the operation easier due to the lever-type handle operation. Complementing the problem is a trend that is widely used compared to the above spindle method.
