Description
Technical Field
The invention relates to a temporary steel rail fixing device which is used for temporarily fixing steel rails in a rail bearing groove of an embedded rail and belongs to the technical field of rail transit.
Background
The rails of the embedded track are embedded in the rail bearing grooves, and no high polymer damping material is used for fixing the rails during maintenance, so that a device for temporarily fixing the rails is needed.
The rail locking tool installed in the rail bearing groove of the embedded rail has the characteristics of narrow space, difficult installation, inconvenient operation, low efficiency and the like, and the tool specially designed for the process is not yet available at home at present, so that the rail locking tool is one of the processes with difficult operation during rail maintenance.
When the track is paved for the first time, temporary rail locking and fixing can be carried out at the plate seam, but the track bed seam of the mature line is filled with compact concrete, so that the on-site installation tool at the plate seam is restricted. Therefore, it is considered that the temporary locking of the rail in the rail bearing groove is performed by specially designing the tool.
Disclosure of Invention
The invention aims at: in order to solve the problems, the temporary fixing device for the steel rail is provided.
The technical scheme adopted by the invention is as follows:
the utility model provides a temporary rail fixing device, includes two L type components and laminating respectively in outside rail support frame, the inboard rail support frame of rail both sides, two establish the bar hole on L type component top horizontal segment and fix on the track slab plane of holding rail groove both sides through the embedded bolt in the track slab respectively, still set up a plurality of telescopic top fixing device on the vertical section of L type component realize with hold the location between the rail groove inside wall, the adjustment backing plate has a plurality of thickness specification can be fit for rail in the different left and right positions of inslot, L type component still realizes vertical restraint with outside rail support frame, inboard rail support frame respectively through limit structure.
After each part is assembled in place, the jacking device is adjusted according to the distance between two sides of the steel rail. The bar-shaped holes on the level of the L-shaped component are used for adapting to the position adjustment. The vertical spacing of the jacking devices on the L-shaped member should be possibly large to provide a large support reaction arm so as to effectively prevent the steel rail from overturning. The outer side steel rail support frame and the inner side steel rail support frame can be made of high-strength insulating materials such as nylon and the like so as to meet the ground insulation requirements of the steel rails.
Preferably, the adjusting backing plates are arranged among the outer steel rail supporting frame, the inner steel rail supporting frame and the L-shaped component and among the horizontal section of the L-shaped component and the plane of the track plate. The adjusting backing plate is used for sealing manufacturing errors, fastening adjustment and reducing impact vibration generated when a train passes.
The limit structure adopts two preferable structures: firstly, the side surfaces of the outer steel rail support frame and the inner steel rail support frame are provided with upward stepped surfaces, the bottom of the vertical section of the L-shaped component is clamped on the stepped surfaces, and on the premise that the L-shaped component is fixed, the side surfaces of the outer steel rail support frame and the inner steel rail support frame cannot be displaced vertically due to the limitation of the stepped surfaces, so that the steel rails are fastened; secondly, limit structure is the profile of tooth cooperation structure that sets up on L type component vertical section and outside rail support frame, inboard rail support frame, and this kind of structure needs L type component and outside rail support frame, inboard rail support frame between contact closely, and profile of tooth cooperation structure selects rectangular tooth as far as possible.
Preferably, the contact surfaces of the outer steel rail supporting frame and the inner steel rail supporting frame with the steel rail are consistent with the rail top and rail bottom contours of the steel rail, so that on one hand, the strength of the rail web of the steel rail is increased, and on the other hand, the standard form of the section of the steel rail is maintained.
In summary, by adopting the technical scheme, the invention can be directly used for temporarily locking the steel rail in the rail bearing groove of the embedded track plate, and has the characteristics of simple structure, simple manufacture and strong practicability.
