Description
Technical field
The utility model belongs to the technical field of rail welding equipment for after-treatment in the seamless railroad site operation, particularly a kind of equipment that is used for the steel rail weld joint aligning.
Background technology
Change at the steel rail laying of gapless track and rail and to repair in the construction, need carry out field Welding, also require to accomplish aftertreatment technologys such as postwelding normalizing, aligning and polishing simultaneously rail.Building-site is handled the lateral bending of welding point easily at present, because the lateral rigidity of rail is little, can accomplish the aligning of rail lateral bending with conventional rail bender (or claiming straight trailer).But the situation to vertical bending (arch up or stay) and wrong head but is difficult to solve, and high-speed railway especially has very high requirement to the glacing flatness of rail, does not allow butt joint to adopt excessive polishing again.Thereby press for the vertical equipment for straightening that can be used for the job site.Because the vertical rigidity of rail is very big, the on-the-spot at present methods that adopt thermal straightenings promptly adopt the heating of oxy-acetylene gas butt joint position more, manage to apply a little relatively external force then, perhaps add to support to change its relative shape, let the rail pyroplastic deformation.The advantage of thermal straightening is that equipment is simple, and is simple to operate, but maximum problem is that the aligning result is wayward, the aligning inefficiency.Since the speed raising of railway, the glacing flatness requirement that has improved gapless track, and thermal straightening technology can't satisfy the glacing flatness requirement of site operation.The scene is needed badly and can be made progress and downward aligning to welding point, and the aligning result manifests, is easy to control and transportable equipment immediately.
The utility model content
The purpose of the utility model just provides the vertical straightener of a kind of flange of rail clamping mobile steel rail welding point; The vertical straightener straightening force of this kind is big; Can vertically align the steel rail weld joint under the state of cooling at the construction field (site), the aligning result is easy to control, and aligning efficient is high; And can move, make things convenient for site operation.
To achieve these goals, the technical scheme that the utility model adopts is, the vertical straightener of a kind of flange of rail clamping mobile steel rail welding point, and its design feature is:
One end of crossbeam is fixed with the bidirectional force applying oil cylinder, and the piston rod of bidirectional force applying oil cylinder bottom links to each other with the application of force frame of inverted U, and application of force frame rides on the rail, and the position that application of force frame is positioned at rail foot is inserted with end pin;
Crossbeam is while and the rectangle upper ledge groove fit of aligning frame one, aligning frame two tops also; Ride on the rail with the lower frame of the inverted U of aligning frame two bottoms, the position that this lower frame is positioned at rail foot is inserted with end pin.
The course of work and the principle of the utility model are:
Before the aligning, straightener put down riding on the rail surface from the upper end of treating straightening of kinked rail, will slide along crossbeam, be located on the weld seam near the aligning frame one of application of force frame; To align frame two again and slide into suitable position along crossbeam; End pin with application of force frame and aligning frame one, two bottoms inserts the installation of promptly accomplishing before aligning then.During aligning; Oil cylinder applies active force up or down through piston rod, application of force frame to rail, thus with application of force frame as the point of application, near the aligning frame one of application of force frame as the resistance point; Aligning frame two is as fulcrum; Utilize lever principle, make rail carry out bending and shear strain, accomplish aligning rail joint.
After aligning was accomplished, the end pin taking-up with application of force frame and aligning frame one, two bottoms can move to next one rail place to be aligned with whole aligning, aligns next time.
Compared with prior art, the beneficial effect of the utility model is:
One, utilizes lever principle to impose enough big straightening force by the bidirectional force applying oil cylinder, can vertically align the steel rail weld joint under the state of cooling at the construction field (site) to rail.Than thermal straightening, its leveling effect directly, be easy to control, efficiency of construction is high.
Two, application of force frame, aligning frame are embraced whole rail; Bidirectional force applying oil cylinder application of force frame and aligning frame can impose enough straightening force downwards, also can upwards impose enough aligning application of forces rail, thereby all can effectively align high joint, low joint and height misconnection head; Two aligning frames can move along crossbeam, thereby can adjust the relative distance of two aligning frames and application of force frame, also are the adjustable ratio of its force arm and resistance arm, can adapt to the aligning of differently curved form welding point.
Three, utilize the principle of lever force-saving to make this straightener can provide enough straightening force, whole straightener is comparatively light again simultaneously; After application of force frame, aligning frame unloaded from rail, whole straightener was convenient to move, and makes things convenient for site operation.
Screw mandrel one, screw mandrel two are installed on the above-mentioned crossbeam, and screw mandrel one, screw mandrel two all links to each other with aligning frame two with aligning frame one respectively through the feed screw nut; Screw mandrel one, the end of screw mandrel two is connected with handwheel respectively.
Like this, drive screw mandrel one, screw mandrel two, can change the position of aligning frame one and aligning frame two easily through handwheel, make more convenient to operate, aligning efficient is higher.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify.
