Description
Technical field
The present invention relates to be applied to the extended-top type arc door hydraulic hoist in the Hydraulic and Hydro-Power Engineering, especially relate to the braced structures of extended-top type arc door hydraulic hoist.
Background technology
In Hydraulic and Hydro-Power Engineering, for satisfying the dam flood-discharge requirement, the wide and height of extended-top type Segment gate port size than many >=1.Therefore, the two suspension centre hydraulic hoists that adopt two hydraulic cylinders to form are controlled the opening and closing of Segment gate more.Conventional extended-top type arc door hydraulic hoist arrange supporting form adopt with two hydraulic cylinders following hang head respectively with gate on two suspension centres is connected, the upper hoisting head of two hydraulic cylinders hangs on respectively and is embedded in the interior hydraulic cylinder of both sides gate pier and props up on the free bearing.Though the layout supporting form of this hydraulic hoist can adapt to the hydraulic hoist design feature and the installation specification of conventional hoisting capacity capacity; (then there is following drawback in hoisting capacity＞2500kN): at first but for the large hydraulic headstock gear; The physical dimension of large hydraulic headstock gear hydraulic cylinder is bigger; Two hydraulic cylinders prop up free bearing, and to stretch out the gate pier sidewall respectively longer; The deadweight and the Qi Menli that add hydraulic cylinder are bigger, and the part distortion that overhangs that causes hydraulic cylinder to prop up free bearing causes amount of deflection to increase, and causes hydraulic cylinder to prop up free bearing virtual center value deviation theory central value; Secondly; There is the installation accuracy requirement at the hinge center that two hydraulic cylinders of extended-top type Segment gate hydraulic hoist prop up free bearing; Because two hydraulic cylinders prop up free bearing and are embedded in respectively in the gate pier of both sides; Can't carry out the secondary adjustment to the deviation that its hinge center occurs after the concrete pouring; A hinge centre-height difference that causes two hydraulic cylinders to prop up free bearing is difficult to guarantee to satisfy at ± 0.5mm and is no more than ± 2mm (" manufacturing installation of Hydraulic and Hydro-Power Engineering headstock gear and standards of acceptance " be the regulation of 7.4.2 (SL381-2007)) with the distance of actual lifting center line with interior, cross central line, causes adverse effect to the even running and the twin-tub Synchronization Control of extended-top type arc door hydraulic hoist.Simultaneously; Since hydraulic cylinder prop up free bearing overhang the part increase; Certainly will to increase hydraulic cylinder and prop up the pre-buried length of free bearing in gate pier; Therefore gate pier need have enough width adequate hydraulic cylinders to prop up the structure needs of free bearing, and this has just limited the orifice number and the gate port size of dam flood-discharge building, and the increasing of gate pier thickness has also increased the engineering quantity and the cost of hydraulic structure.
Summary of the invention
The object of the invention is to provide that a kind of installation accuracy is high, the braced structures of the extended-top type arc door hydraulic hoist of long service life.
For realizing above-mentioned purpose, the present invention takes following technical proposals:
The braced structures of extended-top type arc door hydraulic hoist according to the invention comprises the upstream and downstream side concrete bracket that is arranged on the gate pier sidewall; Side concrete bracket end face is provided with the support girder steel in said upstream and downstream, on said support girder steel, is provided with hydraulic cylinder near downstream and props up hinge;
Said upstream side concrete bracket is made up of fist stage concrete layer and second stage concrete layer from bottom to top; In upstream side concrete bracket one, second stage concrete layer, be vertically installed with many pre-buried joint bars and pre-buried anchor bolt; Said pre-buried anchor bolt passes the upstream side backing plate that is embedded in the second stage concrete laminar surface and extends outside the second stage concrete layer and support the girder steel upstream extremity and be connected through hold-down nut; The pre-buried anchor bolt that is positioned at below the upstream side backing plate is provided with adjusting nut, and said many pre-buried joint bars are fixed with the welding of adjusted upstream side backing plate before the cast of second stage concrete layer;
Said downstream concrete bracket is made up of fist stage concrete layer and second stage concrete layer from bottom to top; In downstream concrete bracket one, second stage concrete layer, be vertically installed with many pre-buried joint bars and pre-buried anchor bolt, said pre-buried anchor bolt passes the downstream backing plate that is embedded in the second stage concrete laminar surface and extends outside the second stage concrete layer and through hold-down nut and be connected with the downstream backing plate; The pre-buried anchor bolt that is positioned at below the backing plate of downstream is provided with adjusting nut; The backing plate upper surface offers groove in said downstream; In said groove, be mounted with the shearing resistance cushion block that exceeds the groove notch; Be welded with junction plate at support girder steel downstream soffit; Offer the down-open recess that adapts with said shearing resistance cushion block shape at said junction plate soffit, support the girder steel downstream and snap onto on the shearing resistance cushion block through said down-open recess, said many pre-buried joint bars and the welding of downstream backing plate are fixing before the cast of second stage concrete layer.
The invention has the advantages that reducing hydraulic hoist props up free bearing distortion and amount of deflection thereof to the adverse effect of Segment gate opening-closing process, is convenient to install and adjust two hydraulic cylinders more and props up the free bearing positional precision to satisfy the service requirement of twin-tub synchronous opening/closing Segment gate.
