The invention discloses a drop hammer impact testing machine, which comprises an iron block, a drop hanger, a wire cable, a grapnel device and a rail holding device. The invention is characterized in that a beam, an upright post, a cross arm and a support are fixed to form a frame of the impact testing machine via screw bolts; a pulley is mounted on the beam and below the upright post; one end of the wire cable is arranged on the beam, and the other end thereof is connected with a power unit through the drop hanger and the pulley; the drop hanger is provided with a drop hanger device for catching and releasing an impact hammer; the rail holding device is fixed in the middle position below the upright post. By using the invention, automatically catching the hammer and automatically decoupling can be realized while the rail cannot change position to finish repeated impact tests, thus saving testing times, reducing labor strength and improving work efficiency greatly.
Description
Technical field
The present invention relates to a kind of testing equipment, more specifically relate to a kind of drop hammer impact testing machine.Be mainly used in the falling weight impact test that detects steel rail welding line.
Background technology
Existing drop impact formula testing machine is total man worker's operation, all tup manually to be hung up suspension hook at every turn after, suspension hook is pulled up to specified altitude, allow the back decontrol tup, by tup deadweight impact specimen, finish once after, rail rollover or from supporting landing.Again rail is carried on support, repeat to install tup to suspension hook, draw high again, decontrol the tup impact specimen again, impacting each time all needs manually-operated, so complicated operation and quite expending time in, rail is heavy, operation field is little, and is very inconvenient, the workman, labour intensity is big, usually impacting its running time each time needs 10-15 to divide kind, and each sample drop-weight test need be finished twice impact usually, for the such sample of rail, each type experiment, need 25 samples of long run test, its weld seam falling weight impact test requires to finish at least continuously 25 times, promptly impacts for 50 times, if use traditional testing machine, it is consuming time huge, and efficient is very low, and labor strength is big.
Therefore, be necessary prior art is improved, design a kind of hammer, automatically-unhooked rail that guarantees simultaneously of grabbing automatically after being impacted, guarantee the testing machine of invariant position, make it can finish repeatedly falling weight impact test continuously.
Summary of the invention
The objective of the invention is to be to provide a kind of drop hammer impact testing machine.Be mainly used in the falling weight impact test that detects steel rail welding line.Thereby grabbing hammer, automatically-unhooked, rail automatically, it can guarantee that invariant position finishes repeatedly falling weight impact test continuously.
The objective of the invention is to be achieved through the following technical solutions:
A kind of drop hammer impact testing machine, it is made up of crossbeam, column, stull, buting iron, rail, suspension hook (band insurance card), wire rope, grapple device, iron ladder, ram hammer, rail clamping device, pressing plate, pulley, support.
Wherein, the grapple device comprises: guide housing, axle, boatswain chair, connecting rod, jig arm, gear shaft.
The rail clamping device comprises: hammer anvil, block.
Its structure constitutes:
Crossbeam by bolt in first column, second column upper end, first stull, second stull all by bolt in first column, the second column centre position, first support, second is supported all and is individually fixed in first column, second column below by bolt, crossbeam, column, stull, support constitute the drop hammer impact testing machine skeleton structure by bolt, pulley, be fixed on the crossbeam, pulley is fixed in the column below, wire rope one end is fixed on the crossbeam, and the other end passes suspension hook, pulley is connected to and is used to draw high suspension hook on the propulsion system.
The grapple device that suspension hook is risen to the bait and is useful on the pick-and-place ram hammer, first boatswain chair, second boatswain chair fuse with first jig arm, second jig arm respectively in the grapple device; First connecting rod, second connecting rod, first jig arm, second jig arm are passed through first, second, the 3rd, gear shaft connects and constitute four-bar linkage structure.
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 present invention 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.
