Embodiment
Specific embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Embodiment 1
See Fig. 1, as shown in legend wherein, a kind of drop hammer impact testing machine, comprising:
One frame 1;
One hoisting gear, comprises drive motor 21, cable disc 22, positioning pulley 23, high-speed cylinder 24, movable pulley 25 and a hawser 26,
One impact weights 3;
And one is subject to mounted mechanism 4;
Positioning pulley 23 is located at the top by mounted mechanism 4;
High-speed cylinder 24 is fixed in frame 1;
Movable pulley 25 is connected on the piston rod of high-speed cylinder 24;
The free end of hawser 26 is walked around on movable pulley 25, positioning pulley 23 successively, and then connects in impact weights 3.
The speed of the piston rod release hawser of high-speed cylinder 24 is greater than the free-fall velocity of impact weights 3.
Introduce principle of work of the present invention below.
Under the driving of drive motor 21, first cable disc 22 discharges sufficiently long hawser 26, the hawser 26 of release is entered by movable pulley 25, when starting to carry out impulse test, start high-speed cylinder 24, the piston rod of high-speed cylinder 24 stretches out, hawser is released rapidly, the speed discharged is faster than the free-fall velocity of impact weights 3, therefore do not need impact weights 3 to be separated with hawser 26 and can carry out impulse test to by mounted mechanism 4, decrease the trouble of repeatedly picking up and hanging impact weights 3, save manpower, improve work efficiency.
Embodiment 2
See Fig. 2, as shown in legend wherein, all the other are identical with described embodiment, and difference is, hoisting gear also comprises four auxiliary pulleys 27.Adopt this structure, make the structure of tension weight churning testing machine compacter.
Embodiment 3
All the other are identical with described embodiment 2, difference is, described drop hammer impact testing machine also comprises a photoelectric sensor, photoelectric sensor is located at by mounted mechanism 4 place, when impulse test completes, photoelectric sensor senses corresponding signal, thus the piston rod controlling high-speed cylinder 24 is retracted rapidly, the impact weights 3 of impulse test is raised rapidly, has avoided the secondary pulse treating test piece.
