The device comprises a support 10, an H-shaped support 101, side beams 102, cross beams 103, rib plates 1, a base 2, limiting columns 3, supporting bolts 4, studs 5, strip-shaped pressing blocks 6, return springs 7, tightening bolts 8 and a cover plate.

Detailed Description

As shown in fig. 1-2, the H-shaped bracket 10 includes two side beams 101, two cross beams 102 are connected between the two side beams 101, a rib plate 103 is arranged between one cross beam 102 and the side beams 101 at two ends, the upper surface of the rib plate 103 is flush with the upper surface of the side beam 101, and the thickness of the rib plate 103 is smaller than that of the side beam 101.

3-4, a high-speed railway H type support frock of polishing, including base 1, have the bearing structure who is used for supporting crossbeam 102 on the base 1, still be fixed with on the base 1 and be used for supporting crossbeam 102 and curb girder 101 seam chamfer spacing post 2, still be equipped with on the base 1 and be used for keeping down the compact structure who presses on crossbeam 102 surface. The pressing structure may be only a pressing plate pressed from above, pressed by a press or the like.

The supporting structure is supporting bolt 3, is fixed with the nut on the base 1, and supporting bolt 3 and nut threaded connection, and base 1 trompil makes supporting bolt 3 can stretch out from base 1 below the nut.

The utility model discloses in, compact structure is including fixing double-screw bolt 4 on base 1, and the cover has the compact heap that is used for pressing in crossbeam 102 top on double-screw bolt 4, and screw-thread fit has the nut on double-screw bolt 4, and the nut is located the compact heap top.

The stud 4 is sleeved with a return spring 6, and the return spring 6 is propped between the pressing block and the base 1.

Still be equipped with puller bolt 7 on the base 1, the compact heap is bar compact heap 5, and the one end pressure of bar compact heap 5 is on crossbeam 102, and puller bolt 7 pushes up in the below of the compact heap other end, is fixed with the nut on the base 1, and puller bolt 7 and nut threaded connection, and base 1 makes puller bolt 7 can stretch out from base 1 in the trompil of nut below.

The working principle is as follows:

firstly, the H-shaped support 10 is placed on a tool, when the H-shaped support is placed, the upper surface of the rib plate 103 faces upwards, then the supporting bolt 3 is supported below the cross beam 102, and the limiting column 2 abuts against the seam chamfer of the cross beam 102 and the side beam 101, so that the H-shaped support 10 can be prevented from moving horizontally. Adjusting each supporting bolt 3 makes H type support 10 roughly level, then presses bar compact heap 5 one end on crossbeam 102, screws up the nut of bar compact heap 5 top, adjusts the other end of tight bar compact heap 5 of the upwards top of jack bolt 7 simultaneously to compress tightly H type support 10. When polishing H type support 10 outer lane, in order to prevent that the process of polishing from rocking, still be stamped apron 8 on the H type support 10, the pressure head has been pressed on the apron 8, pressure head accessible press drive.

After polishing, the nut above the strip-shaped pressing block 5 is unscrewed, and the strip-shaped pressing block 5 bounces under the action of the return spring 6, so that the polishing tool is convenient to detach.

It should be understood that the above description of the specific embodiments is only for the purpose of explanation and not for the purpose of limitation. Obvious changes or variations caused by the spirit of the present invention are within the scope of the present invention.
