Abstract

A lifting tilting flapgate relates to a gate used in hydraulic engineering and comprises a gate leaf and a gate pier, wherein beams at two sides of the gate leaf are respectively provided with a protruding hanger shaft and an upper and a lower protruding cantilever roller wheel; and the gate pier is provided with two vertical gate slots respectively matched with respective corresponding lower cantilever roller wheels and two tracks respectively matched with respective corresponding upper cantilever roller wheels. The lower cantilever roller wheel can be used as a trunnion so that the gate leafcan rotate around the center of the trunnion, or the lower cantilever roller wheel can roll in the gate slot so that the gate leaf can rise and tilt out of the water surface to overhaul position. Theregular start or close operation of a gate is the same as that of the flapgate. When overhaul is needed and the gate is in close position, the upper cantilever roller wheel of the gate is put in place and the gate topples over to form a lifting tilting gate. By adopting the roller wheels to substitute for the fixed trunnion in the prior art, the gate simultaneously has the advantages of the flapgate and the lifting tilting gate and overcomes the defects that the flapgate is difficult to overhaul and the lifting tilting gate affects navigation.

Description

Lifting and horizontal flap gate

[ technical field ] A method for producing a semiconductor device

The invention relates to a gate for hydraulic engineering.

[ background of the invention ]

In hydraulic engineering, lifting horizontal gates and flap gates are widely applied. Wherein,

the flap gate is a rotary flat gate, i.e. the gate leaves rotate around hinges fixed on the foundation (gate pier or bottom sill) to open and close the gate, and the hinges can be arranged in the middle or at the bottom of the gate leaves.

The lifting gate is also a plane gate, when closed, the gate is vertically arranged in the hole, after the gate is lifted and opened, the gate leaf moves along a certain track, and finally, the gate leaf horizontally lies above the hole.

Problems and disadvantages of existing gates: the flap gate of the bottom support hinge is operated by a hoist and rotates around the support hinge, turns over and sinks into water, lies down on the gate bottom plate to open, and stands up to close. When the gate is fully opened, no building is arranged in the orifice and on the upper part of the orifice, the flow capacity is high, and navigation is not influenced. However, the gate is connected to the foundation by a hinge, and the water surface overhaul cannot be carried out. When the lifting-horizontal type gate is fully opened, the lifting-horizontal type gate horizontally lies above the orifice, so that the navigation height is limited, and particularly the navigation hole with high channel grade is formed.

[ summary of the invention ]

The invention aims to provide a lifting type flap gate which can rotate and lift, can be easily overhauled and does not influence navigation.

The lifting horizontal type flap gate comprises a gate leaf and gate piers, wherein edge beams on two sides of the gate leaf are respectively provided with a protruding hanging shaft and an upper cantilever roller and a lower cantilever roller; two vertical gate slots respectively matched with the lower cantilever rollers and two tracks respectively matched with the upper cantilever rollers are arranged on the gate pier.

Wherein, the bottom of the vertical door slot is preferably semicircular.

Furthermore, the rails on the gate piers are preferably arranged horizontally or obliquely.

Wherein, the upper cantilever roller can be preferably provided with a folding device or a rotating device or a telescopic device; when the folding device is arranged, the upper cantilever roller can extend out of the edge beam or be folded in the door leaf through the folding device; when the rotating device is arranged, the upper cantilever roller can extend out of the boundary beam or be rotated in the door leaf through the rotating device; when the telescopic device is arranged, the upper cantilever roller can extend out of the boundary beam or be retracted into the door leaf through the telescopic device.

The lower cantilever roller can be used as a hinge, so that the door leaf can rotate around the center of the hinge; the gate can roll in the gate slot, so that the gate leaf can be lifted to a maintenance position from a horizontal water outlet surface, and the opening and closing operation of the gate in the horizontal process is the same as that of a flap gate. Therefore, the roller wheel is adopted to replace a fixed support hinge in the prior art, so that the gate has the advantages of a flap gate and a lifting horizontal gate at the same time, and the defects that the flap gate is difficult to overhaul and the lifting horizontal gate affects navigation are overcome. In addition, the invention is provided with the upper cantilever roller which can be hidden in the door leaf at ordinary times. Therefore, when the gate is in a closed position, the cantilever roller (hidden in the gate leaf at ordinary times) on the gate extends out of the leaf gate, the gate inclines during opening and closing operations, the gate becomes a lifting gate, the upper cantilever roller travels on a horizontal track on the gate pier, the lower cantilever roller rolls in a vertical gate slot on the gate pier, and the gate leaf can be lifted above the water surface for maintenance.

[ detailed description ] embodiments

The invention is further described below with reference to the accompanying drawings.

The invention relates to a lifting horizontal flap gate, which consists of a gate leaf and a gate pier.

The door leaf 1 is composed of a beam system structure, and the edge beams on two sides of the door leaf 1 are respectively provided with an upper cantilever roller 4, a protruding hanging shaft 3 and a protruding lower cantilever roller 2; the gate pier is provided with a vertical gate slot 7 and a horizontal rail 5. Wherein, the upper cantilever roller 4 can be preferably provided with a folding device or a rotating device or a telescopic device so that the upper cantilever roller 4 can be hidden in the door leaf 1 or extend out of the boundary beam; in this embodiment, the upper and lower cantilever rollers 4 are provided with a rotating device, so that the upper cantilever roller 4 is extended out of the edge beam or rotated in the door leaf 1 by the rotating device.

The gate pier is provided with two vertical gate slots 7 and two rails 5. Wherein, each vertical door slot 7 is respectively matched with the corresponding lower cantilever roller 2, and each track 5 is respectively matched with the corresponding upper cantilever roller 4. Wherein the rails 5 may preferably be arranged horizontally or obliquely, in the present embodiment horizontal rails are used.

The gate normally lies on the gate bottom plate.

When the gate is required to be closed, the hydraulic hoist 6 is connected with the hanging shaft 3, so that the hydraulic hoist 6 pulls the hanging shaft 3 to enable the gate leaf 1 to rotate upwards around the lower cantilever roller 2 at the semicircular bottom 7 of the vertical gate slot of the gate pier until the gate leaf 1 is upright, and the water blocking of the orifice can be closed.

And the opening process of the gate is vice versa. When the gate is required to be opened, the hydraulic hoist 6 is connected with the hanging shaft 3, so that the hydraulic hoist 6 pushes the hanging shaft 3 to enable the door leaf 1 to rotate downwards around the lower cantilever roller 2 (supported on the semicircular bottom of the vertical door slot 7 of the gate pier) until the door leaf 1 is horizontal, and then the opening can be opened for drainage and navigation.

When the gate needs to be overhauled, the gate is in a closed position, the upper cantilever roller 4 of the gate is rotated 180 degrees from a hidden position in the gate leaf 1 to be in place, the hydraulic hoist 6 is connected with the hanging shaft 3, the gate is rotated downwards around the lower cantilever roller 2 by pushing the hanging shaft 3, the gate is inclined, the upper cantilever roller 4 is in contact with the horizontal rail 5 of the gate pier, and the gate becomes a lifting gate. The connection between the hydraulic hoist 6 and the hanging shaft 3 is released, then the installation position of the hydraulic hoist 6 is adjusted to be connected with the lower cantilever roller 2, so that the hydraulic hoist 6 lifts the lower cantilever roller 2, the upper cantilever roller 4 moves on the horizontal rail 5 of the gate pier, and the gate is lifted to be above the water surface for maintenance.
