Description
Technical field
The present invention relates to a kind of link that rail beam is installed that is used for, especially, but relate to tension and the adjustable bindiny mechanism that a kind of rail beam is used.
Background technology
The rail beam that track traffic is used is placed on the substructure such as buttress by bindiny mechanism, train is in the load of high-speed cruising, the weight that comprises rail beam self all passes to substructure again by bearing, general bearing all possesses stronger anti-pressure ability, yet, under specific situation, also can produce bigger when train is exercised in orbit to upper pulling force, for lighter rail beam, be not enough to overcome this pulling force in its deadweight, the bearing that traditional rail beam is used is not only resistance to compression but also can tension ground constraint tracks beam all.
For example, at application number is 01126627.9, name is called in the Chinese invention patent ublic specification of application of " regulatable supporter " provides a kind of bindiny mechanism that is used for rail beam, the top board of this bindiny mechanism is placed on the footstock, the circular pit at footstock bottom surface middle part just in time inlay card at upper ball base, lower ball base is seated in the cavity of double-screw bolt, the spherical crown of upper ball base is inserted in the ball bowl of the lower ball base that matches with it, form ball pivot, this bindiny mechanism relies on the bearing corner that the adjustable nodel line of ball pivot road is vertical or the horizontal curve superelevation causes, also can regulate the angular deviation that the making error because of rail beam or substructure bent cap causes, but the big pulling force that causes during by rail beam when train can make top board and footstock, footstock separates with being connected of lower ball base with upper ball base or upper ball base, so this bindiny mechanism can only be used to connect the bigger rail beam of deadweight.
Again for example, be 03150862.6 at application number, name is called the bindiny mechanism that a kind of adjustable superposed beam is provided in the prospectus of application for a patent for invention of " adjustable superposed beam hookup ", this bindiny mechanism has one to connect pull bar, pass track plate, adjusting device and spandrel girder successively, be provided with nut, locking nut at the two ends that connect pull bar, such punching structure makes bindiny mechanism can't make slidably form, only can be used for the fixedly connected mechanism of staked type rail beam.
In order to solve the tension of the bindiny mechanism that rail beam uses, also have a kind of known technology to adopt the scheme of combined isolator, promptly adopt two resistance to compression bearings cooperate again outward a mode tensile supporting seat with realize can resistance to compression again can tension function, but it is bigger to regulate difficulty, bearing quantity is also more, so practicality is not enough.
Therefore, need a kind of bindiny mechanism of practicality of energy tension to come the constraint tracks beam.
Summary of the invention
The object of the present invention is to provide a kind of bindiny mechanism that can tension again can measuring body rail beam uses, this bindiny mechanism is simple in structure, and cost is lower, and is convenient to be provided with as required the assembly of adjustable track beam space position.
In order to solve the technical problem, tensile adjustable connection mechanism for orbit beam of the present invention comprises and is used for the last embedded board of fixedlying connected with rail beam, the top board of fixedlying connected with last embedded board, screw rod, locking nut, base is with lock-screw and be used for the following embedded board of fixedlying connected with buttress, described screw rod is connected with described base by thread, described locking nut rotation set is on described screw flight, described locking nut is connected with described base by lock-screw, described base is connected with following embedded board, be characterized in, also comprise: the first lower slider plate, one end is a convex surface; Second upper sliding plate, one end are concave surfaces; And go up buckle, and having a supporting surface, the other end of described second upper sliding plate is seated on the described supporting surface, and the described buckle of going up is fixedlyed connected with described top board; One end of described screw rod is provided with flange and its end face is a concave surface, the soffit of described flange is a convex surface, the described first lower slider plate cooperates rotatably by its convex surface and the concave surface of described screw rod and is seated between described top board and the described screw rod, and described screw rod cooperates with the concave surface of described second upper sliding plate rotatably by the convex surface of its flange.
