Abstract
The utility model discloses a cross-existing railway bridge construction roller hanging basket, and the technical scheme thereof is that: a front supporting leg and a rear supporting leg are installed on a slideway; a main beam, a column and a diagonal draw bar constitute a triangle combination beam; a front upper beam is installed at a front end of the main beam; rear anchor poles are pre-embedded in bridge concrete; and carrying pole beams are pressed at a rear part of the main beam and are connected with the rear anchor poles. An application method comprises steps of: anchoring the slideway by the rear anchor poles; jacking up the triangle combination beam; disposing round steel rollers on the front leg; then dismounting the rear anchor poles; and pulling forwards the roller hanging basket with a chain block to allow the roller hanging basket to slip in place. As the round steel rollers are additionally arranged between the front leg and the main beam to move the center of gravity of the roller hanging basket backwards, a frictional force in the movement is reduced, a construction task of moving the hanging basket can be completed only in one and a half hours and the task of moving the hanging basket during a skylight period of train traveling on the existing railway can be fully realized, thereby ensuring the operation of the existing railway to be safe and timely.
Description
Technical field
The utility model 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, 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.
The utility model content
Hang blue existing defective in order to overcome present construction; The utility model discloses a kind of railway existing line bridge construction roller bearing of striding and hang indigo plant, 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 of the utility model 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.
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.
