Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of drop impact experimental provision, including guide rail 14, is socketed with weight 8 on guide rail 14, leads
Weight can be adsorbed in electromagnetic disc by the top setting electromagnetic disc or hoisting mechanism, electromagnetic disc of rail 14 in conduction, be powered off
When weight is discharged.If hoisting mechanism is arranged, existing hoisting mechanism, the steel of 8 top of weight setting and hoisting mechanism are selected
The hook of cord connection carries out the release of weight by the folding of hook and the movement of hoisting mechanism and packs up.
Two perpendicular to the ground are at least arranged in guide rail 14, and 8 sets of weight on guide rail 14.
As shown in figures 1 and 3, weight 8 includes downwardly convex ontology 10, for applying impact force to measured object 15, this
It is outwardly extending support edge 9 at the side margins on 10 top of body, there is slide opening 17 on support edge 9,17 sets of slide opening in guide rail 14
On, it is slided along guide rail 14.
Support component is arranged in the lower part of two guide rails 14, the position opposite with weight 8, is used to support the support edge of weight 8
9, reduce or prevent weight 8 from injuring during falling and bouncing to the repeat impact of measured object.
As shown in Figure 1, support component includes at least two groups bottom support 2, two groups of bottom supports 2 are disposed on bottom
On plate 1, measured object 15 is arranged on the bottom plate 1 between two groups of bottom supports 2, and the distance between two groups of bottom supports 2 are answered
The ontology of weight 8 can be made to pass through, but support edge 9 can not be made to pass through, is i.e. the top that is located at two groups of supporting elements 2 of support edge 9.When
Weight 8 is to when falling, and ontology 10 impacts measured object, and support edge can be supported on the top of bottom support 2.
Wherein, in the upper plane of bottom support 2, it is fixed with rubber layer 4, rubber layer 4 can absorb the elastic force of weight 8,
Reduce the rebound of weight 8.
Bottom support 2 may include the hollow cabinet being arranged on bottom plate 1, cabinet include setting 4 lower part of rubber layer,
The support plate 5 that rubber layer 4 is supported；Support plate 5 is fixed as one with rubber layer 4 or is seperated.Under support plate 5
The box house in portion, setting are supported support plate 5, and the lifting device 3 of raising step-down operation is carried out to support plate 5.
Existing achievable structure can be used in above-mentioned lifting device 3.Such as air cylinder lifting device or hydraulic lifting apparatus.
As shown in Figure 1, the utility model provides a kind of specific embodiment of lifting device, which is existing
Air cylinder lifting device.Its principle is identical as the principle of cylinder chair lift.
As shown in Figure 1, lifting device 3 includes the cylinder 16 being mounted on bottom plate 1, it is upper that cylinder 16 is divided by piston rod 6
Portion space and lower space, the lower space of cylinder 16 are connect by tracheae 12 with external high-pressure air source, are arranged on tracheae 12
Valve 11；The upper space of cylinder 16 connects piston rod 6, and piston rod 6 is connect with support column 7, and support column 7 connects support plate 5.When
When entering high-pressure air source from valve 11, piston rod 6 is jacked up upwards, so that support column 7 supports support plate 5.
The device of the utility model further includes the opposite side of cabinet for being separately positioned on two groups of opposite bottom supports 2
Opposite type sensor 13, opposite type sensor 13 connect controller, controller connecting valve 11.13 course of work of opposite type sensor
In, when weight is fallen, and stops the work of opposite type sensor 13, controller receives signal, and control valve 11 is opened, so that being promoted
Device work, jacks up the weight 8 for having carried out overbump experiment.
Controller can also be prolonged by time relay connecting valve 11 by the unlatching that valve 11 is arranged in the time relay
When, when for receiving the signal of opposite type sensor in controller and open signal is passed to valve 11, when being delayed preset
Between send valve 11 to again, carry out the work of lifting device, prevent from not impacting tester 15 in weight 8 being elevated dress
Top set rises, and the time setting of the time relay is set as the case may be.
