Removably it is connected with clump weight 25.
Hammer body component 3 when in use, flexibly can individually select 1 falling impacts steering gear of hammer body examination according to weight needs
Sample 11 present embodiments provides a kind of hammer body by different size in three and forms, including the first hammer body 21, the second hammer body 22 and
Three hammer bodies 23.Can the first hammer body 21 be used alone, the first hammer body 21 and the second hammer body 22 falling impacts sample together also can be selected,
First hammer body 21, the second hammer body 22 and third hammer body 23 falling impacts sample together, the synchronization fallen together to ensure more hammer bodies
Property, positioning pin 27 is fitted between each hammer body.Each hammer body can by way of increasing or reducing clump weight 25 tune
Whole tup quality.
In the present invention, main machine frame 1 is equipped with 2 locking of control hammer body component and grabbing for whereabouts takes off hammer device 3.Grab de- hammer dress
3 are put as self-locking device, in the case of hammer body component 2 connected and fix by the device, form self-locking, ensure to make in gravity
Tup will not occur under and fall phenomenon.
As shown in figure 5, grabbing de- hammer device 3 includes ontology 31, it is provided through being oriented to the guide hole 32 of polished rod on ontology 31,
The side of ontology 31 is equipped with the first telescoping cylinder 33 that can be stretched up and down, and 33 lower end of the first telescoping cylinder is connected in horizontally toward mechanism
The second telescoping cylinder 34 that side is stretched is connected with corresponding limiting in the front end of the second telescoping cylinder 34 and is plugged below hammer body component 2
Limited block.First telescoping cylinder 33 can be corresponded to according to the height of hammer body is retractable to suitable position in order to which the second telescoping cylinder 34 correspondence makes
With.
The middle part for grabbing the ontology 3 of de- hammer device 3 is equipped with lock-up cylinder 35, and lock-up cylinder 35 can be drivingly connected thereunder
Scroll chuck folding and clamping realize the locking to hammer body component to link up with 28 on locking hammer body component 2.Preferably, de- hammer is grabbed
The inductive switch of 28 positions of sensing hook is additionally provided on device 3,28 disengaging locking positions are linked up with without using in state, such as detecting
It puts, then inductive switch is connected, warning device prompting abnormality alarm.
In use, the second telescoping cylinder 34 drives limited block to retract to both sides, hammer body component 2 is detached from, lock-up cylinder 35 starts
Scroll chuck is controlled to unclamp release shackle 28.The release altitude of hammer body component 2 can control to adjust reality by grabbing de- hammer device 3
It is existing.
2 tup 24 of hammer body component fallen is acted on to steering gear sample 11, at this time force snesor, displacement sensor and speed
After the data of degree acquisition system acquisition are simultaneously acquired signal processor 10, force value-displacement of entire impact moment is formd
Curve or force value-rate curve or displacement-rate curve to host computer 9 and are shown.
In the present invention, anti-secondary pulse device 5 is equipped in the lower section of main machine frame, anti-secondary pulse device 5 is to work as hammer body
During 2 falling impacts sample steering gear 11 of component, if hammer body component 2 is bounced by Percussion counter-force, 4 anti-secondary pulse devices 5 are examined at this time
Slowdown monitoring switch is triggered, and anti-secondary pulse device 5 starts, and is pushed by electromagnet and advanced on stopper, the 5 hammer body groups that will decline again
2 stroke of part blocks, to prevent hammer body component 2 from doing secondary pulse work(to 11 surface of steering gear sample, to ensure impact results as one
Secondary falling impacts cause, it is ensured that the accuracy of experiment.
After the completion of primary test, put forward hammer system 4 and the hammer body component 2 fallen be lifted up to certain altitude, can again into
Row experiment.Hammer system 4 is put forward mainly by chain drive hammer body component 2 being driven to move up by promoting motor-driven drive sprockets.
