Abstract

The invention discloses an improving method for a crest outlet plane operating gate and a structure thereof. Gate leaves of the gate are provided with corresponding main beam height and structures according to the size of bearing loads, fixed wheel devices of each gate leaf are provided with corresponding wheel diameters and tread width according to the size of the bearing loads, the distances between the outer panel edges of all the gate leaves and fixed wheel treads are same, the gate leaves are connected by adopting pin shafts, and water stopping devices are arranged among the gate leaves. The gate has the certain flexibility while the using performance of materials is fully played and investment is saved, therefore, the gate can regulate the position by performing small displacement when the gate bears the loads to prevent disengagement, and it can be effectively guaranteed that the fixed wheel devices make close contact with a track in a gate slot and operate smoothly and steadily.

Description

A kind of improved method of table hole plane operating gate and its structure

Technical field

The present invention relates to a kind of improved method of table hole plane operating gate and its structure, belong to Hydraulic and Hydro-Power Engineering gate Technical field.

Background technology

For table hole plane operating gate, gate is generally made up of girder height identical gate flap from top to bottom, gate flap it Between using being welded to connect, supporting typically adopts wheel footpath identical fixed wheel device, and gate girder bearing load is different from top to bottom, Fixed wheel device bearing load differs greatly, and girder and fixed wheel bearing load general top gate flap lower part gate flap are little, according to phase With girder and fixed wheel device, can cause that gate flap waste of material is more, economy is poor；Additionally, every section door leaf fixed wheel device holds Differed greatly by load, the track deformation gap contacting with fixed wheel can be led to larger, between gate flap, gate rigidity is made using welding Very greatly it is not easy to adjustment displacement, the less fixed wheel of bearing load therefore can be made to come to nothing, cause adjacent fixed wheel device load unexpected Increase more, destroy, then cause engineering accident, so prior art is still not perfect.

Content of the invention

It is an object of the invention to for overcoming the deficiencies in the prior art, providing a kind of improvement side of table hole plane operating gate Method and its structure.

Technical scheme is as follows:

Present invention firstly provides the improved method of such a table hole plane operating gate, the method is from upper by gate To under be made up of upper section door leaf, the middle section door leaf of varying number and lower section door leaf, wherein go up section door leaf setting contour with side bar I shape girder, the section door leaf setting box beam contour with side bar in upper section, in remaining, section door leaf setting span centre is highly big, and two End is symmetrical and deck-molding is contracted to the box beam contour with side bar, and the span centre height of middle section door leaf box beam gradually increases from top to bottom Greatly, lower section door leaf setting span centre is highly big, and two ends are symmetrical and deck-molding is contracted to the box beam contour with side bar, gate every section door leaf Girder height and structural shape can be determined according to bearing load and economic deck-molding, more conventional gate rational height phase from top to bottom With the pattern of girder, good economy performance.

Adopt bearing pin to be flexibly connected between gate flap, internode sets antipriming, and the gate flap of gate has certain flexibility, make every Section door leaf stress is relatively independent, and the load that the fixed wheel device of every section door leaf bears is affected very little by other gate flaves.Every section door leaf The outside side bar in the both sides up and down of girder arranges four fixed wheel devices, the load almost phase that every section door leaf fixed wheel bears can be made With, fixed wheel device is identical, then after the fixed wheel device pressure-bearing of every section door leaf also almost identical with rail contact deformation it is ensured that fixed wheel The contact with track for the device closely, effectively prevents coming to nothing of fixed wheel device.

Wheel footpath and tread width, by being gradually increased arrangement, are held from top to bottom every section door leaf fixed wheel device with it from top to bottom The load being subject to is gradually increased adaptable.The panel outer rim of all gate flaves is identical to the distance of fixed wheel tread, adopts pin between gate flap Axle connects, and internode sets antipriming, giving full play to materials'use performance, so that gate is had certain soft while reducing investment outlay Property, gate flap can be made in bearing load to make thin tail sheep adjustment position, prevent from coming to nothing, be effectively ensured fixed wheel device in gate slot with Rail contact closely, operate steadily.

Based on said method, a kind of improved structure of table hole plane operating gate of the present invention is such that in cleaning door Setting table hole plane operating gate in groove；Table hole plane operating gate by upper section door leaf, middle section door leaf one, middle section door leaf two and under Section door leaf forms；The girder one of upper section door leaf is uiform section I shape, and girder one is highly identical with side bar one；Upper section door leaf is being led On the outside side bar one in the both sides up and down of beam one, four fixed wheel devices one are set；Middle section door leaf one setting and the girder one of upper section door leaf Contour box type girder one；Four fixed wheel devices two are arranged on the box type girder one both sides external edge beam two of middle section door leaf one；In Section door leaf two arranges the box type girder two of variable cross-section；Four are arranged on the outside side bar three in box type girder two both sides of middle section door leaf two Fixed wheel device three；Lower section door leaf arranges the box type girder three of variable cross-section；The outside side bar four in box type girder three both sides of lower section door leaf Four fixed wheel devices four of upper setting.

Wherein, pin shaft device is adopted to connect between gate flap, internode sets antipriming.

Due to employing technical scheme, the gate flap of this kind of gate is arranged accordingly according to the size of bearing load Girder height and structure, the fixed wheel device of every section door leaf arranges corresponding wheel footpath and tread width according to the size of bearing load, The panel outer rim of all gate flaves is identical to the distance of fixed wheel tread, adopts bearing pin to connect, internode sets antipriming between gate flap, Give full play to materials'use performance, while reducing investment outlay, make gate have certain flexibility, gate can be made in bearing load Make thin tail sheep adjustment position, prevent from coming to nothing, be effectively ensured fixed wheel device in gate slot with rail contact closely, operate steadily.
