Abstract

The utility model discloses a lifting horizontal type flap gate, relating to a gate for hydraulic engineering, and comprising a gate leaf and a gate pier, wherein the gate leaf consists of a girder system structure, and a protruding hanger shaft and an upper protruding cantilever roller and a lower protruding cantilever roller are arranged on both girders at the two sides of the door leaf; and the gate pier is provided with two vertical gate slots which are respectively matched with the corresponding lower cantilever rollers and two tracks which are respectively matched with the corresponding upper cantilever rollers. The lower cantilever roller of the utility model can be used as a trunnion, so that the gate leaf can rotate around the center of the trunnion and also can roll in the gate slot, and thereby the gate leaf can be lifted out of the water lever until reaching an overhaul position in a horizontal mode. The start and stop operations of the gate in the ordinary days are the same with that of the flap gate; when overhauling is needed to be carried out and the gate is positioned in a close position, the upper cantilever roller (which is concealed in the gate leaf) of the gate is positioned, the gate is inclined, so the gate can become the lifting horizontal type flap gate. The utility model adopts the roller to substitute a fixed trunnion in the prior art, so that the gate simultaneously has the advantages of a flap gate and a lifting horizontal type gate, and overcomes the defects that the flap gate is hard to be overhauled and the lifting horizontal type gate affects the navigation.

Description

Lifting tilting flapgate

[technical field]

The utility model relates to a kind of hydraulic engineering gate.

[background technology]

In hydraulic engineering, rise horizontal gate and flap gate than having of extensive use.Wherein, flap gate is a kind of rotary type flat gate, and promptly gate flap rotates and to make gate opening and closing around being fixed on a hinge on the basis (gate pier or end bank), and a hinge can be arranged on the middle part or the bottom of gate flap.

Rising horizontal gate also is a kind of plane gate, and for standing upright in the aperture, after gate promoted and opens, gate flap was put down at last and crouched above the aperture along orbital motion definitely during closing gate.

The problem and the shortcoming of existing gate: the bottom is propped up the flap gate gate of hinge and is operated by headstock gear, rotates around a hinge, and the upset submerged is lied down on gate floor to opening, and erecting is the pass.In the aperture and top, aperture does not have building during the gate standard-sized sheet, and conveyance capacity is big, does not influence navigation.But gate is hinged and connected on the basis maintenance of can't leaving the water by propping up.Flat crouching above the aperture when rising horizontal gate standard-sized sheet limited headway, the navigation hole that especially waterway classification is high.

[summary of the invention]

That the utility model aims to provide is a kind of not only rotatable, but also liftable, can the simple and easy lifting tilting flapgate that overhauls and do not influence navigation.

Lifting tilting flapgate of the present utility model comprises gate flap and gate pier, and gate flap is made up of the girder system structure, and all respectively is provided with an outstanding hanging axis, two outstanding cantilever rollers up and down on the side bar of gate flap both sides; Gate pier is provided with the track that two vertical gate slotes that are complementary with each self-corresponding lower cantalever roller respectively and two are complementary with each self-corresponding upper cantilever roller respectively.

Wherein, described vertical gate trench bottom is preferably semicircle.

In addition, the level or be obliquely installed preferably of the track on the gate pier.

Wherein, described upper cantilever roller can be provided preferably with folding device or tumbler or stretching device; When folding device is set, the upper cantilever roller by this folding device by extended outside side bar or be folded in the gate flap; When tumbler was set, the upper cantilever roller was extended outside side bar or be rotated in gate flap by this tumbler; When stretching device was set, the upper cantilever roller was extended outside side bar or be retracted in the gate flap by this stretching device.

Lower cantalever roller of the present utility model can be used as a hinge, makes gate flap to rotate around a hinge center; Also can in gate slot, roll, make gate flap to rise and crouch out the water surface to overhauling the position.Gate keying operation at ordinary times is identical with flap gate; When needing maintenance, when gate is in the closed position, make gate upper cantilever roller (being hidden in the gate flap at ordinary times) stretch out leaf outdoors, gate has a down dip in the headstock gear operation, gate just becomes the horizontal gate of liter, the upper cantilever roller is walked on the horizontal rail on the gate pier, rolls in the vertical gate slot of lower cantalever roller on gate pier, and gate flap can rise the above maintenance of the water surface that crouches.

The utility model adopts roller to replace fixing in the present technology to cut with scissors, and makes gate have flap gate and the advantage that rises horizontal gate simultaneously, has overcome flap gate and has been difficult to overhaul, rise the shortcoming of Wo Men influence navigation.

[specific embodiment]

Further specify the utility model below in conjunction with accompanying drawing.

Lifting tilting flapgate of the present utility model is made up of gate flap and gate pier.

Wherein, gate flap 1 is made up of the girder system structure, and is equipped with a upper cantilever roller 4, outstanding hanging axis 3, an outstanding lower cantalever roller 2 on the gate flap 1 both sides side bar; Gate pier is provided with vertical gate slot 7 and horizontal rail 5.Wherein, upper cantilever roller 4 can be provided preferably with folding device or tumbler or stretching device and makes upper cantilever roller 4 to be hidden in the gate flap 1 or to stretch out outside side bar; In the present embodiment, what upper and lower cantilever rollers 4 was provided with is tumbler, and upper cantilever roller 4 stretches out outside side bar by tumbler or is rotated in gate flap 1 like this.

Described gate pier is provided with two vertical gate slotes 7 and two tracks 5.Wherein, every vertical gate slot 7 is complementary with each self-corresponding lower cantalever roller 2 respectively, and every track 5 is complementary with each self-corresponding upper cantilever roller 4 respectively.Wherein, track 5 is horizontal arrangement or be in tilted layout preferably, in the present embodiment, has adopted horizontal rail.

Gate is flat at ordinary times to crouch at the gate floor place.

In the time of need closing, be connected with hanging axis 3 by hydraulic hoist 6, upwards rotation is upright until gate flap 1 in the semicircular base 7 of the vertical gate slot of gate pier around lower cantalever roller 2 so hydraulic hoist 6 pulling hanging axises 3 make gate flap 1, can close the aperture dash.

Otherwise gate opening procedure.In the time of need opening, be connected with hanging axis 3 by hydraulic hoist 6, so hydraulic hoist 6 promotes hanging axises 3 gate flap 1 is rotated down until gate flap 1 level around lower cantalever roller 2 (being bearing on the semicircular base at the vertical gate slot 7 of gate pier), can opens aperture draining, navigation.

When needing Emergency Gate, gate is initially located in fastening position, make gate upper cantilever roller 4 in place from 180 ° of hiding position rotations in the gate flap 1, be connected with hanging axis 3 by hydraulic hoist 6, by promoting hanging axis 3 gate is rotated down around lower cantalever roller 2, gate run-off the straight like this, thus upper cantilever roller 4 is contacted with the horizontal rail 5 of gate pier, and gate just becomes the horizontal gate of liter.Untie being connected of hydraulic hoist 6 and hanging axis 3, adjust the installation site of hydraulic hoist 6 then, it is connected with lower cantalever roller 2, so hydraulic hoist 6 promotes lower cantalever roller 2, upper cantilever roller 4 moves on the horizontal rail 5 of gate pier, gate is risen to crouch to mention more than the water surface overhaul.
