Description

Underwater steel gate structure capable of realizing rapid blind grabbing

Technical Field

The utility model relates to an underwater steel gate structure for realizing rapid blind grabbing, and belongs to the field of underwater steel gate mechanical technology.

Background

At present, a domestic power plant circulating water steel gate is generally placed at the bottom of a well along a guide rail after being grasped by a grapple, a travelling steel wire rope for hanging the grapple is loosened (not stressed), a balance weight on the grapple is pulled to a loose hook position, the grapple claw is contracted to be separated from a hanging hole of the steel gate, the grapple can ascend along the guide rail, and the steel gate is left at the bottom of the well. If need hang the shaft bottom steel gate under water again, the grapple is down to the shaft bottom along the guide rail, wait to grapple on the steel gate, when the wire rope on the driving is not atress, pull the balancing weight on the grapple to working position, promote the wire rope, rely on jack-up personnel and maintainer to feel whether the wire rope atress, whether both sides balance valve on the steel gate are all opened and judge whether the claw accurately gets into in the steel gate hanging hole. After the balance valve is opened, water in front of the gate enters the water collecting well behind the steel gate. When the water levels at the two sides are the same (the front and rear differential pressure reaches balance), the steel gate is lifted away from the water.

The underwater operation can not directly confirm whether the grapple correctly enters the steel gate hanging hole by naked eyes. The position where the grapple stays can not be accurately positioned, and the grapple can only be operated by virtue of experience of lifting personnel and maintenance personnel, so that great potential safety hazards exist. In the conventional steel gate lifting process, the phenomenon that the steel gate falls off to the bottom of the well caused by the fact that the claw does not reliably enter the steel gate lifting hole when the steel gate is lifted to a higher position occurs.
