The rail clamping device is fixed first column, centre position, second column below, be used for clamping rail sample, make its unlikely rollover when being hit, wherein first block, second block are fixed on the hammer anvil, rail are placed between first block on the hammer anvil, second block, owing to the distance between first block, second block is 170MM, the rail foot surface width is 150MM, therefore, rail can not be turned on one's side after catching a packet, and can only keep original position.
The drop hammer impact testing machine principle of work is:
Drawing high suspension hook by wire rope makes the grapple device rise, when the grapple device rises, its four-bar linkage structure makes and makes the jig arm of winning, second jig arm firmly grasp ram hammer by its deadweight, make ram hammer rise with the grapple device, when rising to the buting iron position, buting iron pushes first boatswain chair, second boatswain chair opens the jig arm of winning, second jig arm and ram hammer breaks off relations and does the movement of falling object, thereby the impact specimen rail is finished the one-shot test.
Compared with prior art the utlity model has following tangible advantage:
The fast automatic hammer of grabbing, automatically-unhooked, and not clot of automatically-unhooked rear steel rope, be provided with special clamping rail bearing, repeatedly the drop impact rail all can not turned on one's side, pound a sample and needed 15 minutes originally, now only need 2 minutes, press iron mark TB/T1632.2-2005 standard, will pound for one group of pattern sample of rail that 25 drop test of rail weld seams do not rupture could be qualified, every drop-weight test 3.8 meters highly need to repeat continuously 2 times continuous, this drop hammer impact testing machine has been saved test period greatly, and reduced labour intensity, thereby improved work efficiency greatly.
