Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of impact performance test, and particularly relates to a geophysical impactor performance test device. BACKGROUND

[0002] People often calculate the impact force and impact energy of an impactor by means of a spring impact, the impact force can be obtained by the spring force corresponding to the compression amount of the spring, and the impact energy can be obtained by calculating the work done by the spring from the initial state to the post-impact state, so as to correspond to the impact energy. Since the spring needs to be kept in place after reaching the limit position, the ratchet bar is the most commonly used one-way limiting mechanism.

[0003] However, since the ratchet bars are arranged in an array, the measurement accuracy is limited by the size of the ratchet teeth. Generally speaking, the smaller the size of the ratchet teeth and the more dense the distribution, the higher the measurement accuracy, but the weaker the braking force of the ratchet teeth, which is actually a contradictory problem that cannot be fundamentally solved.

[0004] Based on the above situation, the present application proposes a geophysical impactor performance test device for limiting spring return by changing pre-tightening force and friction. SUMMARY

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present application proposes a geophysical impactor performance test device with high accuracy (not limited by the size of the ratchet teeth), which changes the friction by changing the pre-tightening force, and can adaptively adjust the frictional resistance. In order to overcome the technical contradiction that the size of the ratchet teeth cannot be too large or too small, the present application creatively proposes a double-ring staggered adaptive pre-tightening clutch mechanism and a pre-tightening force adaptive linkage adjustment mechanism, which is linked by the pre-tightening force adaptive linkage adjustment mechanism. By changing the repulsive force between the driving sliding inner ring and the driven sliding outer ring, the sliding pre-tightening force between the double-ring staggered adaptive pre-tightening clutch mechanism and the test reading guide mechanism is adjusted. Without any sensor and control system, only by means of ingenious mechanical structure, the technical target of adaptively adjusting the pre-tightening force and the friction (reducing the friction when impacted, and restoring the friction when the impact is removed) is achieved, and the technical contradiction that the accuracy and strength of the general one-way limiting mechanism cannot be considered is solved.

The linkage articulated link 17 is symmetrically provided with link articulated portions 19 at two ends. The link articulated portions 19 at the two ends of the linkage articulated link 17 are respectively located in the inner ring clamping groove 10 and the outer ring clamping groove 14. The linkage articulated link 17 is articulated with the inner ring articulated seat 9 through one set of the link articulated portions 19. The linkage articulated link 17 is articulated with the outer ring articulated seat 13 through another set of the link articulated portions 19. Through the linkage of the linkage articulated link 17, the support force of the linkage articulated link 17 on the driven sliding outer ring 6 can be reduced when the driving sliding inner ring 5 slides, so as to reduce the sliding resistance of the driven sliding outer ring 6. The linkage articulated link 17 also limits the relative sliding direction of the driving sliding inner ring 5 and the driven sliding outer ring 6. The pre-tightening spring 18 is arranged between the inner ring cantilever platform 11 and the outer ring cantilever platform 15.

[0047] As shown in Figure 6 , Figure 7 , Figure 9 , Figure 12 The double-ring misalignment type self-adapting pre-tightening clutch mechanism 1 comprises a driving sliding inner ring 5 and a driven sliding outer ring 6.

The driving sliding inner ring 5 is slidably arranged on the test reading guide mechanism 3 through the inner ring fixed surface 7. The driving sliding inner ring 5 is provided with an inner ring outer ring 8. The driving sliding inner ring 5 is annularly and uniformly provided with inner ring articulated seats 9 on the inner ring outer ring 8. The middle position of the inner ring articulated seat 9 is provided with an inner ring clamping groove 10. The driving sliding inner ring 5 is also annularly and uniformly provided with an inner ring cantilever platform 11 on the inner ring outer ring 8. The inner ring cantilever platform 11 and the inner ring articulated seat 9 are correspondingly arranged. The driven sliding outer ring 6 is provided with an outer ring skeleton 12. The driven sliding outer ring 6 is annularly and uniformly provided with outer ring articulated seats 13 on the outer ring skeleton 12. The outer ring articulated seat 13 is provided with an outer ring clamping groove 14.

[0048] In specific use, first, the user needs to start the impactor body 33. When the impact head 34 of the impactor body 33 impacts at high speed, it will impact on the hollow resistance cylinder 25.

[0049] The hollow resistance cylinder 25 is impacted and then slides laterally along with the active sliding inner ring 5 fixed thereto, and is sleeved on the inner boss 28 of the box, at this time the inner boss 28 of the box limits the movement direction of the hollow resistance cylinder 25;

[0050] When the active sliding inner ring 5 slides laterally, the linkage articulated connecting rod 17 is pulled, the included angle between the linkage articulated connecting rod 17 and the sliding direction is reduced, the downward swing of the linkage articulated connecting rod 17 overcomes the elastic force of the pre-tightening spring 18, so as to reduce the pre-tightening force and the frictional resistance between the outer ring friction surface 16 and the box friction surface 29;

[0051] Since the frictional resistance between the outer ring friction surface 16 and the box friction surface 29 has been reduced, the driven sliding outer ring 6 will slide along with the active sliding inner ring 5 until the resistance of the pre-tightening spring 18 is increased to be sufficient to overcome the impact force of the impact head 34;

[0052] After the impact head 34 is unloaded, the hollow resistance cylinder 25 rebounds under the elastic force of the resistance generating spring 24, at this time the linkage articulated connecting rod 17 no longer has the downward swing trend, and the pre-tightening spring 18 is reset, the pre-tightening force and the frictional force between the outer ring friction surface 16 and the box friction surface 29 also return to the initial state, at this time the relative position between the driven sliding outer ring 6 and the cylindrical box 23 is fixed again;

[0053] Due to the limitation of the linkage articulated connecting rod 17, the hollow resistance cylinder 25 fixed in the active sliding inner ring 5 cannot be reset, at this time the relative position between the driven sliding outer ring 6 and the cylindrical box 23 is observed through the box observation window 27, and the impact force of the impact head 34 can be read.

[0054] The above is the overall working process of the present application, and the next time the step is repeated.

[0055] It should be noted that, in this text, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
