Abstract
The invention discloses a bridge construction rolling shaft hanging basket across railway existing line and a use method thereof. The invention has the technical scheme that a front support leg and a rear support leg are installed on a slide way, a main beam, a vertical column and a diagonal draw bar form a triangular combination beam, an upper front cross beam is installed at the front end of the main beam, a rear anchor rod is precast in bridge concrete, and a carrying pole beam rests on the rear part of the main beam and is connected with the rear anchor rod. The use method comprises the following steps of: anchoring the slide way by using the rear anchor rod, jacking up the triangular combination beam, placing a round steel rolling shaft on the front support leg, removing the anchor rod, and pulling the rolling shaft hanging basket forward by using a chain block to slide in place. Because the center of gravity of the rolling shaft hanging basket moves backward by adding the round steel rolling shaft between the front support leg and the main beam, the friction force during movement is reduced, the construction task of moving the hanging basket can be finished within 1 h 30 min, the task of moving the hanging basket is finished at a train sunroof point on the existing line, and the effect of safely and timely ensuring the normal operation of the existing line is achieved.
Description
Technical field
The present invention relates to a kind of special construction apparatus of striding the railway existing line, specifically is that a kind of roller bearing of striding railway existing line bridge construction is hung indigo plant and method for using thereof, belongs to the railway construction machine field.
Background technology
In the construction of railways process; Inevitably will run into the existing railway line of leap and construct continuously, and the normal passing train of existing line is very frequent, like Beijing-Guangzhou Railway passing 240 multiple rows every day; Average per 10 minutes through row; In order to guarantee the enforcement safety of the passing train of existing line, crossing over the existing line construction must quick, accurate, timely, orderly carrying out, and the engineering time generally confirms not have the period that EMUs pass through in morning at night; No longer than two hours, be called " skylight " time.To in the so short time, accomplish construction continuously, just construction equipment proposed higher requirement.What generally adopt at present is cradle construction; Its front leg strut of Hanging Basket is positioned under the column; Because the Hanging Basket center of gravity is forward, causes Hanging Basket front fulcrum place frictional force bigger, Hanging Basket is more time-consuming when mobile; Can not guarantee in " skylight " smooth, safe Hanging Basket is moved into place in the time also do not have a kind of desirable railway to stride the existing line construction at present and hang blue equipment.
Summary of the invention
Hang blue existing defective in order to overcome present construction; The invention discloses a kind of railway existing line bridge construction roller bearing of striding and hang indigo plant and method for using thereof, be with the reach of Hanging Basket front leg strut, and between front leg strut and girder, add three road round steel roller bearings; Move after making the Hanging Basket center of gravity, the Hanging Basket mobile security is quick.
The technical scheme that railway of the present invention is striden existing line bridge construction ball extension indigo plant is following:
Lay two slideways, a front leg strut and a rear support leg are installed on every slideway, front leg strut is placed directly on the slideway; The rear support leg left-hand thread is respectively being installed a girder on each front leg strut with on the rear support leg on slideway, top rail after the girder middle part connection; Column is installed on the infall of girder and back top rail, and back top rail is arranged at the column below, and column is arranged on the top rail of back; Back top rail connects girder, and girder connects column, is connected with diagonal member between column and the girder; Girder, column and diagonal member are formed a triangle compound beam, top rail before the connection of girder front end, and preceding top rail is connected respectively with the back lower transverse beam with preceding lower transverse beam and back top rail; Bed die longeron and preceding lower transverse beam and back lower transverse beam are connected, are connected pre-buried anchor pole afterwards in bridge concrete with binding-beam between column and the column; Shoulder pole girder be pressed in the girder rear portion and with the back anchor pole link to each other, 3-5 root shoulder pole girder is set behind the girder, establish the 6-10 root after anchor pole it is carried out anchoring; A rear support leg is set in rear end, girder bottom and tightly cuts, 3-5 root round steel roller bearing is installed above the front leg strut and is tightly cut with girder with the slideway steel plate.
The method for using that roller bearing of the present invention is hung indigo plant is following:
A. at first use the back anchor pole that the slideway anchoring is firm; Remove the back anchor pole of triangle compound beam then; At this moment the triangle compound beam by left-hand thread wheels left-hand thread on slideway; Prevent that the triangle compound beam from toppling, subsequently at triangle compound beam front end with jack with triangle compound beam jack-up, on front leg strut, place three round steel roller bearings immediately;
B. remove the back anchor system, it is reliable to guarantee that each anchoring piece connects, and under the track blockade situation, is spurred forward by jack and roller bearing is hung blue slippage puts in place, simultaneously preceding top rail, preceding lower transverse beam, back top rail, back lower transverse beam, bed die longeron synchronization-sliding is put in place;
C. slideway will be laid smooth straightly, must not squint, and guarantees that the left and right sides is evenly synchronous, and left-hand thread is on slideway all the time to keep the left-hand thread wheels, and the girder front end is wanted timely cushioning, and main beam rear end is established anchor and compressed, in order to avoid topple, girder moves on to the shoulder pole girder of anchoring in time behind the position;
D. after the reach of roller bearing Hanging Basket puts in place; In time carry out anchoring; With the absolute altitude and the axis of jack adjustment roller bearing Hanging Basket, guarantee that roller bearing Hanging Basket front and rear fulcrum is on the same horizontal plane, and the longitudinal midline of whole roller bearing Hanging Basket is overlapped with bridge axes then; Tighten back anchor connector, make the back anchor pole stressed the jack unloading.
Roller bearing Hanging Basket front leg strut is moved forward; And between front leg strut and girder, add the round steel roller bearing; Move after making roller bearing Hanging Basket center of gravity, reduced the frictional force when the roller bearing Hanging Basket moves, only needed 1 hour 30 minutes can accomplish the construction task that Hanging Basket moves; Can in existing line is driven a vehicle skylight point, accomplish Hanging Basket fully and move task, reach safety and in time guaranteed the normal effect of runing of existing line.
