Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments is provided with reference to the accompanying drawings.
Referring to fig. 1-7, which are schematic views of an embodiment of a cover plate according to the present invention, the embodiment of the present invention provides a cover plate for covering a pit surface in a crash test, and the cover plate includes a frame 1 and a transparent panel 4 movably disposed in the frame 1. The levelness of the frame 1 and the levelness of the transparent panel 4 are both adjustable, so that the upper surface of the cover plate and the surface of the test track are always in the same plane, and the test is smoothly carried out.
The frame 1 of the above-mentioned cover plate comprises a plurality of cross beams 2 and a plurality of longitudinal beams 3 and 301 crossing each other in the same plane to form support cells between adjacent cross beams 2 and adjacent longitudinal beams 3 and 301. In the present embodiment, as shown in particular in fig. 1, 2 and 3, there are three longitudinal beams 3 and 301, four transverse beams 2, and the transverse beams 2 extend substantially perpendicularly to the three longitudinal beams 3 and 301. In this case, a total of six support units can be formed between the adjacent cross member 2 and the adjacent longitudinal members 3 and 301, and each support unit has a rectangular shape. Of course, in other alternative embodiments, the cross beam 2 and the longitudinal beams 3 and 301 may have other suitable numbers, and the cross beam 2 and the longitudinal beams 3 and 301 may intersect at other suitable angles, and the formed support unit may have other non-rectangular shapes.
In the present embodiment, one transparent panel 4 is supported in each of the supporting units. Although not shown, the transparent panel 4 may include an upper layer composed of a first material and a lower layer composed of a second material, the first material being different from the second material, wherein the upper layer detachably covers over the lower layer. Specifically, the upper layer may be a soft glass plate with a lower material strength, and the lower layer may be a glass plate with a higher material strength. Since the lower, mainly supporting glass plate is usually expensive, the upper, soft glass plate can thus serve as its protective layer. When the soft glass sheet has a damage such as scratch due to a plurality of tests, it is possible to easily replace a new layer of the soft glass sheet. Since the soft glass plate is relatively inexpensive, such a double-layer structure saves costs while ensuring the supporting strength of the transparent panel 4, compared to replacing the glass plate as a whole. In other alternative embodiments, the upper layer of the first material and the lower layer of the second material may also be other transparent materials as appropriate, for example, the upper layer may be a transparent plastic layer, etc. In addition, where bottom imaging is not required, the upper layer of soft glass may be replaced with a sheet of the same material as the test rail, such as a steel or iron sheet, and designed to simulate the shape of the rail surface.
The frame 1 of the invention is required to be in an absolute horizontal position when being arranged, the error is ensured not to exceed 1 degree after a plurality of tests, meanwhile, the frame 1 is required to be regularly checked at intervals, and if the included angle between the frame 1 and the levelness exceeds 1 degree, the frame 1 is required to be adjusted to ensure that the frame 1 is horizontal. It is therefore important to adjust the entire frame 1 and how the adjustment is made simpler.
In the invention, a support element and a first adjusting device can be fixedly arranged in each support unit. Wherein the supporting element is intended to support the transparent panel 4 and the first adjusting means are intended to cooperate with the supporting element in order to adjust the levelness of said transparent panel 4 with respect to the plane of the frame 1. Therefore, the upper surface of the transparent panel 4 and the upper surface of the frame 1 can be kept on the same plane, so that the upper surface of the whole cover plate is parallel to the horizontal plane, and the test requirements are met. And the relative position of the frame 1 and the collision pit is not influenced by the adjustment, so that the test efficiency is further improved.
In the present embodiment, as shown in particular in fig. 3, each support element may in particular comprise four support blocks 5 fixedly connected to the rectangular support unit and spaced apart from each other. Each supporting block 5 is approximately in the shape of a right triangle and is respectively arranged at four corners in the supporting unit, so that the adjustment is more convenient and accurate. Specifically, as shown in the uppermost left corner of fig. 3, two right-angle sides are respectively and fixedly disposed on the adjacent cross beam 2 and the longitudinal beams 3 and 301, and the manner of disposing the support blocks 5 at other positions is similar, which is not described herein again.
In addition, each first adjusting means may be an adjusting bolt 6 provided on each support plate 5. Specifically, each supporting block 5 is provided with a threaded hole perpendicular to the plane of the frame 1, the threaded hole is in threaded connection with the adjusting bolt 6, and the adjusting bolt 6 can be used for acting on the transparent panel 4, so that the adjusting effect is achieved, the structure is simple, the cost is saved, and the adjustment is convenient and fast. Wherein the support blocks 5 are evenly arranged in the support unit for ease of adjustment, the number of support blocks 5 may be determined according to the shape of the support unit, corresponding to the alternative embodiment of the support unit described above, if the support unit is of another shape.
Similarly, while the whole frame 1 is kept horizontal, the transparent panel 4 in the frame 1 is also ensured to be kept horizontal, the levelness error of the transparent panel 4 cannot exceed 0.1 degree, and therefore, the transparent panel 4 also needs to be checked regularly, and needs to be adjusted timely if the error range is exceeded. Therefore, the adjustment of the transparent panel 4 is also important.
Therefore, the frame 1 of the cover plate of the invention can also comprise a second adjusting device for adjusting the levelness of the plane of the frame 1 and the horizontal plane, so as to ensure that the upper surface of the frame 1 and the surface of the test rail are in the same plane and meet the test requirements. In addition, in other alternative embodiments, a second adjustment device may also be used in conjunction with the first adjustment device, so that the frame 1 can more easily meet the test requirements.
In this embodiment, as can be seen from the drawings other than fig. 2, the second adjusting device may include four fixing plates 8 fixedly connected and uniformly arranged on the two outer side longitudinal beams 301 of the frame 1, and the plate surfaces of the fixing plates 8 may be parallel to the nearest inner wall of the pit. And as shown in particular in fig. 3, the four fixing plates 8 are in particular located at the four respective intersections formed by the two central cross members 2 and the two outer longitudinal members 301 of the frame 1. Two long round holes 9 are symmetrically formed in each fixing plate 8, and the length direction of each long round hole 9 is basically perpendicular to the plane where the frame 1 is located. The moving direction of the frame 1 is limited by the length direction of the oblong hole 9 on the fixing plate 8, and can be fixed with the inner wall of the pit through bolts. In this way, on the one hand, the frame 1 is provided with an adjusting function, and in addition, the structural stability of the whole cover plate 1 in the test process can be further enhanced and the structure is simple no matter the moving direction of the frame 1 is limited or the frame 1 is fixed with a collision pit. Compared with the traditional test, the invention meets the test requirement only by adjusting the frame 1, avoids maintaining the collision pit as much as possible, saves the cost and improves the efficiency. In other alternative embodiments, the number of the fixing plates 8 may be other, and may also be determined according to the number of the intersection points of the cross beam 2 and the longitudinal beams 3 and 301. Similarly, the number of oblong holes 9 in the fixing plate 8 may be other numbers.
In addition, a bolt matched with the long round hole 9 can be arranged in the long round hole, the bolt can relatively slide in the long round hole but cannot fall off from the long round hole, and a threaded hole matched with the bolt can be arranged on the inner wall of the pit, which is parallel to the fixed plate 8 and is closest to the fixed plate. When the bolt passes through the oblong hole 9 of the fixing plate 8 and then is screwed into the threaded hole on the inner wall of the pit, but not screwed, the whole frame 1 can move along the direction vertical to the plane of the test track relative to the bolt along with the fixing plate 8. When the frame 1 is not required to move, namely the upper surface of the frame 1 is on the same plane with the horizontal plane, the fixing plate 8 and the inner wall of the pit on the corresponding side can be fixed by screwing the bolts, so that the whole frame 1 is fixed.
In the embodiment of the invention, as shown in fig. 1 in particular, the surface of the middle longitudinal beam 301 is provided with a longitudinally extending groove, which can be used as a traction rail for a traction trolley in a test process, and the traction rail is a moving rail for the traction trolley and a traction steel wire rope, so that the test use requirements are met. And the bottom of the middle longitudinal beam 301 is fixedly welded with a reinforcing rib 9 extending longitudinally, so that the strength of the track is ensured, and the structural strength of the whole frame 1 is enhanced.
Also, the present embodiment may further include a rib plate 10 connected to the cross beam 2 and the fixing plate 8, respectively. Specifically, a rib plate 10 may be disposed on a surface of the fixing plate 8 away from the nearest inner wall of the pit, and the rib plate 10 is parallel to and fixedly connected to the second beam 2. As can be seen in fig. 3, 6 and 7, the rib plate 10 is substantially in the shape of a right triangle, wherein one of the right-angled sides is fixed to the plate surface of the fixing plate 8, and the other right-angled side is fixed to the corresponding cross beam 2. The rib plate 10 is used for enhancing the connection strength of the fixing plate 8 and reducing stress concentration, so that the fixing plate 8 is more stable, and the structural stability of the frame 1 is stronger. And the ribbed slab 10 is parallel arrangement in the bottom that corresponds crossbeam 2, and the projection of ribbed slab 10 just coincides with corresponding crossbeam 2, so can not influence experimental normal clear. In addition, the right-angle side of the rib plate 10 is fixedly arranged between the two symmetrical oblong holes 9 on the fixing plate 8, so that the matching use of the oblong holes 9 and the bolts is not influenced.
The installation principle of the embodiment of the invention is as follows:
firstly, the frame 1 of the whole cover plate is placed on a collision pit, a boss can be specifically arranged in the pit, the position of the boss corresponds to two outer side longitudinal beams 301 of the frame 1, the two outer side longitudinal beams 301 are just placed on the corresponding bosses, and at the moment, the upper surface of the frame 1 and the surface of a test track are in the same plane. After the installation is finished, the following four fixing plates 8 are used for assisting in fixing, and specifically, the fixing plates 8 and the inner wall of the pit are fixed through screwing bolts. The fixing plate 8 not only has the auxiliary fixing function, but also has the function of finely adjusting the levelness of the whole frame 1. Generally, after the frame 1 is firmly fixed, the movement amount is very small, and only the displacement amount is 1 ° to 2 °, so that when the bolt on the fixing plate 8 is not screwed, the frame 1 can be adjusted by fine adjustment such as manual adjustment, and then the bolt is screwed for fixing. Once the frame 1 is secured, the transparent panel 4 in the support unit of the frame 1 is placed.
In other alternative embodiments of the present invention, the second adjusting means is not limited to the structure and form of the above-described embodiments, and may be other various ones. For example, the second auxiliary device may be a support frame having a base and a telescopic support rod, and the telescopic power may be provided by an electric motor or a hydraulic mechanism. The support frame base is fixedly arranged on the ground inside the collision pit, and the top of the support rod is fixedly connected with the bottom of the longitudinal beams 3 and 301 of the frame 1. Similarly, the frame 1 can be adjusted by controlling the extension and retraction of the supporting rod, when the upper surface of the frame 1 and the surface of the test track are in the same plane, the extension and retraction are stopped, and the locking is performed, so that the effect that the fixing plate 8 is fixed by the bolts is achieved. Similarly, the supporting element and the first auxiliary device may be matched with each other by a structure similar to the supporting frame, the supporting frame base is used to replace the supporting block 5, the supporting rod is used to replace the adjusting bolt 6, and the transparent panel 4 is adjusted by controlling the extension and contraction of the supporting rod.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
