Abstract
The utility model relates to a rolling production field of rail especially relates to a prevent device of rail cold scratch, a serial communication port, including mesa, flute profile seat, connecting plate and bearing, be equipped with the flute profile seat in a row on the mesa, the bearing is fixed in the flute profile seat by square head axle, and mesa bottom surface both ends are passed through the connecting plate and are linked to each other with the base of walking beam exit position, are equipped with a deviation value H to walking beam exit direction between the central line of two adjacent rows of bearings. The deviation value H is 16-20 mm. Compared with the prior art, the beneficial effects of the utility model are that: the rolling contact, not the sliding contact, is generated between the red hot steel rail and the cooling bed, the cold scratch phenomenon of the steel rail is basically avoided, and the yield of products is effectively improved.
Description
Technical field
The utility model relates to steel rail rolling production field, relates in particular to a kind of device that prevents the cold scratch of rail.
Background technology
In steel rail rolling is produced, when rail is carried on cold bed, the chain and swing chain and scratch of being easily fixed, in rail head side, circular arc place produces cold scratch, and the scratch degree of depth at 0.3～0.5mm not etc., produces defective work, greatly affects the lumber recovery of product.
Summary of the invention
The purpose of this utility model is to provide a kind of device that prevents the cold scratch of rail, in the exit position of step rate, the rolling table top that prevents scratch rail is installed, and makes to produce and roll rather than slide between rail and cold bed, improves product lumber recovery.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of device that prevents the cold scratch of rail, comprise table top, flute profile seat, connecting plate and bearing, table top is provided with flute profile seat in a row, bearing is fixed in flute profile seat by square head shaft, bottom surface of table top two ends are connected with the pedestal of step rate exit position by connecting plate, between the center line of adjacent two row's bearings, are provided with a deflection value H to step rate Way out.
Described deflection value H is 16～20mm.
Compared with prior art, the beneficial effects of the utility model are: make to produce rolling between red heat rail and cold bed and contact rather than sliding-contact, substantially stopped the cold scratch phenomenon of rail, effectively improved the lumber recovery of product.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the side view of Fig. 1.
In figure: 1-table top 2-flute profile seat 3-connecting plate 4-bearing 5-square head shaft 6-pedestal
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is a kind of device example structure schematic diagram that prevents the cold scratch of rail of the utility model, comprise table top 1, flute profile seat 2, connecting plate 3 and bearing 4, table top 1 is provided with flute profile seat 2 in a row, bearing 4 is fixed in flute profile seat 2 by square head shaft 5, table top 1 two ends, bottom surface are connected with the pedestal 6 of step rate exit position by connecting plate 3, between the center line of adjacent two row's bearings 4, are provided with a deflection value H to step rate Way out.Deflection value H is 16～20mm, and embodiment middle (center) bearing is deep groove ball bearing 206, and its deflection value H is 16mm.
During assembling, first some groups of bearings 4 are fixed in flute profile seat 2, then several groups of flute profile seats 2 are in a row fixed on table top 1, finally by connecting plate 3, table top is fixed on pedestal 6.Can below table top 1, add backing plate according to actual needs, adjust the height of table top, when rail is carried on cold bed, can successfully slide on device bearing.
Claims (2)
