It is good that non-fragment orbit has a track ride comfort, globality is strong, lateral stability is good, structure height is low, how much states are lasting, and advantage such as low maintenance capacity, economic results in society be remarkable, more and more come into one's own, more country is all endeavouring employing and development non-fragment orbit engineering, and has obtained tremendous development.The extensive use of non-fragment orbit engineering on high-speed railway will be trend of the times.At present, China's non-fragment orbit has formed various ways such as double-block type ballastless track, CRTSI template formula non-fragment orbit and CRTSII template formula non-fragment orbit, has developed the non-fragment orbit of different structure forms such as two piece flush types, vertical linking-board type and unit be board-like.Concrete sleeper mostly is site prefabrication greatly, namely builds prefabricated factory at the railway construction temporary site, produces required concrete sleeper.Concrete sleeper after prefabricated is sent to the railway construction job site again and lays.The laying of non-fragment orbit sleeper comprises that supporting layer construction, leg are installed, the steel form track is installed, railway roadbed slab muscle is laid, the cast of railway roadbed board concrete, sleeper are installed, wiped one's face and operation such as maintenance.During concreting, because that the sleeper interblock is built the scope of operation is little, the discharging of concrete mix, vibrates, floatingly all can the precision of the section of track be impacted.The concrete discharging is too fast, easily causes the floating rail level height that influences of the section of track, and concrete vibrating and personnel trample and easily cause section of track off normal.In work progress, improve the laying precision of non-fragment orbit sleeper, significant to traffic safety and the raising speed of a motor vehicle, be subjected to people's attention.
The utility model content
In order to overcome the defective of prior art, the utility model proposes a kind of side-pressing device for the non-fragment orbit sleeper laying, the precision when being conducive to improve the non-fragment orbit sleeper laying.
In order to solve the problems of the technologies described above, the side-pressing device that is used for the non-fragment orbit sleeper laying that the utility model provides, comprise door shaped stent, first bolt assembly, at least one cover second bolt assembly, described door shaped stent has first lateral column, back timber, second lateral column that is fixedly connected sequentially; Described back timber has axial mounting hole; The screw rod of first bolt assembly passes described mounting hole, and the nut of described first bolt assembly is positioned at the outside of described door shaped stent back timber; The screw rod of described second bolt assembly is hinged by its nut and described second lateral column.
Further, as one of improvement project of the present utility model, be used for the side-pressing device of non-fragment orbit sleeper laying, the head of the screw rod of the screw rod of described first bolt assembly and second bolt assembly is square toes.
Further, as two of improvement project of the present utility model, be used for the side-pressing device of non-fragment orbit sleeper laying, the length of described first lateral column is short than the length of second lateral column.
Further, as three of improvement project of the present utility model, the side-pressing device that is used for the non-fragment orbit sleeper laying, described second lateral column has the boss that protrudes to both sides away from the back timber end, makes second lateral column away from the width of the back timber end width greater than second other position of lateral column.
Further, as four of improvement project of the present utility model, be used for the side-pressing device of non-fragment orbit sleeper laying, second bolt assembly is two covers, is articulated in the both sides of described second lateral column respectively.
Further, as five of improvement project of the present utility model, for the ease of the recycling of product, be used for the side-pressing device of non-fragment orbit sleeper laying, the external surface that the screw rod of described first bolt assembly is implanted the concrete part also scribbles bar planting glue.
Above-mentioned improvement project can be implemented alone or in combination under the situation of not conflicting.
In use, the screw rod of first bolt assembly is fixed in the concrete of the base of the rail or is fixed on the concrete face of the base of the rail by special glue, first lateral column is pressed in the surface of non-fragment orbit sleeper, second lateral column is pressed in the concrete surface of the base of the rail, by screwing the nut of first bolt assembly, make side-pressing device compress the non-fragment orbit sleeper; Simultaneously, by rotating the screw rod of second bolt assembly, its screw rod and the steel form of laying sleeper are pushed against.Thereby sleeper is fixedly positioning in concrete cast and maintenance processes, have higher laying precision.
The beneficial effect that the utility model brings: the side-pressing device that is used for the non-fragment orbit sleeper laying that the utility model provides, can avoid floating rail level height and the displacement in the horizontal direction of restriction sleeper, the raising laying precision of influencing of sleeper in use.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
