Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of whole proving installation;
Accompanying drawing 2 is the front elevational schematic of proving installation;
Accompanying drawing 3 is the proving installation schematic diagram after removing crossbeam;
Accompanying drawing 4 is the schematic top plan view in accompanying drawing 3.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in Figures 1 to 4, a kind of four square table fatigue test devices, comprise base 1, four square tables 2 to be tested are located on base, base is respectively equipped with the air pump 3 of 4 horizontal extensions outside 4 sides of four square tables, be respectively front air pump, rear air pump, left air pump, right air pump, the top of four square tables is provided with crossbeam, vertical flexible top air pump 4 is provided with bottom crossbeam, top air pump is positioned at four square table end face centers, each air pump tail end of described horizontal extension to be located on an air pump column 5, air pump column bottom is located on base, above-mentioned each air pump front end is fixed with the shock boss 31 of shock four square table side, and each air pump is connected with counter and control module, every root air pump is singly connected with counter and control module, air pump stretches start-stop counter with regard to record once, after adopting the technical program, the continual shock of air pump that four sides of four square tables are subject to 4 horizontal extensions, reach a daily test effect by cross shear of simulation, simultaneously, table top also has a top air pump, for clashing into desktop straight down, be used for simulating the test effect of desktop by vertical pressure, the fatigue resistance of multi-faceted test desktop, each air pump is connected with counter and control module, test report can be provided after having tested, certainly unidirectional test can be carried out separately, have more and test targetedly.
Described air pump column comprises front column, rear column, left column, right column, every root air pump column bottom is provided with slide block, described base is provided with the horizontal direction sliding rail 11 mated with slide block, the horizontal slip of air pump column is in runner rails, so just can free adjustment air pump impingement position, can select to clash near edge, also can select the middle part of clashing into side, sliding rail sidewall is provided with long lumbar hole 12 in addition, is installed with bolt for fixing air pump column in long lumbar hole; Every root air pump column self described is in addition provided with vertical slide rail 51, slide rail can be preferably dovetail slide rail, the air pump of horizontal extension vertically slides in slide rail, because the kind of a lot of four square tables is different, highly also different, if limit the height of dead air pump, then limit the scope surveyed of this proving installation, so utilize adjustable for height function to considerably increase the test specification of this proving installation, be applicable to four square tables of differing heights.
4 corners are fixed with 4 skeletons 13 to described base, every root skeleton top top links 14 connects, comprise two diagonal line connecting rods at front rod, back link, left connecting rod, right connecting rod and center, described crossbeam is two diagonal line connecting rods, such framed structure stability is better, two diagonal line connecting rods not only increase the stability of framework as crossbeam, also eliminate along band the steel setting up crossbeam specially, cost-saving; Further, horizontal slip track is provided with bottom described front, rear, left and right connecting rod, described air pump column top is slided respectively bottom corresponding top links, which adds the stability of air pump column, because air pump can be subject to recoil strength when clashing into desktop side, air pump column is only fixedly connected with in bottom, and its top easily produces and rocks under the effect of recoil strength, is also slided at air pump column top after bottom top links and then can avoid this problem well; In addition, the target of testing in this programme is antifatigue test, antifatigue test is continuation forces testing, but not disposable impact test, so the shock boss on air pump should select nonrigid object as far as possible, if irony or steel be easy to desktop side is crashed through, so preferably, described shock boss 31 is plank or rubber bodies.
In addition, different types of four square tables, the spacing of its 4 table pin is not identical, can be installed on base to meet multiple four square tables, described base is hinged with 4 disks 15, the center of disk is pin joint, each disk is circumferentially with the jack 151 of more than 2 along its center of circle, 4 table pin of four square tables are inserted in the jack of 4 disks respectively, during disk rotational, the corresponding change of jack interval on two disks, in order to adapt to the table pin of different-diameter size, the diameter of the jack on disk is also not quite similar, general diameter is chosen as 4mm, 6mm, 8mm, 10mm, 12mm.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, and its concrete structure allows to change, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
