Fig. 4 is a cut-open view of the present invention.
Embodiment
Following structure accompanying drawing is further described the present invention by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 3, fork truck overhead guard impact test apparatus comprises m shape hook 1, and the one side roof part is connecting and articulates piece, articulate in the piece on respectively portion be provided with mounting hole and pilot hole; The bottom surface of three cylinders in left, center, right, its underpart has inner groovy respectively, and three inner groovies connect; Be provided with turning block 2 by pin in the inner groovy of right side cylinder; The other end of turning block 2 is corresponding with the inner groovy of hook middle part cylinder, is connecting connection straight-bar 5 by pin in the inner groovy of left side cylinder, and the other end that connects straight-bar 5 is connecting H shape connecting link 4 by drawing pin 13; H shape connecting link 4 other ends are connecting sliding shoe 3; The other end of sliding shoe 3 is positioned at the inner groovy of hook middle part cylinder, and the abutting end of sliding shoe 3 and turning block 2 is the wedge shape, the corresponding contact matching of its wedge surface.
Rear portion, m shape hook 1 left side is connecting guard bar 7, guard bar 7 lower ends contact with the vertical pole of H shape connecting link 4, upper end one side of guard bar 7 is connecting retracing spring 22, and the other end of retracing spring 22 is connecting the piece that articulates at hook 1 top, and the upper end opposite side of guard bar 7 is connecting stay cord;
Front portion, m shape hook 1 left side is provided with the connecting link pulley by axle, strides around stay cord on the connecting link pulley, and the stay cord other end is connecting and draws pin 13.
The inner groovy bottom surface of m shape hook middle part cylinder is connecting supporting plate 6, and supporting plate 6 extends to H shape connecting link 4 bottoms, and the elongated end of supporting plate 6 is provided with adjusts bolt 20.
The trystate of this device is seen Fig. 1, and test block is mounted on by wire rope on the mounting hole of turning block 2 and hook, and as seen from Figure 2, supporting plate 6 is welded on the hook 1, forms sliding tray.Its course of work is: during test, guard bar 7 is pulled maximum position to the right, be moved to the left sliding shoe 3, make turning block 2 open; The load lifting rope is placed on the turning block, promotes sliding shoe 3 to the right, guard bar 7 is put back to original position; The load of slinging after rising to specified altitude, is drawn the F1 rope, opens and protects limit bar 7, draws the F2 rope then, and sliding shoe 3 is moved to the left, and turning block 2 is thrown off, the load free-falling, as shown in Figure 4.
This device utilizes turning block 2, sliding shoe 3, H shape connecting link 4 and connects straight-bar 5 when being in linear position, forms the principle at mechanical dead point, and load is realized auto-lock function; When drawing pin 13 places to apply pulling force, changed original equilibrium state, sliding shoe 3 is moved to the left, thus load comes off.The effect of supporting plate 6 is to prevent from H shape connecting link 4 and connect straight-bar 5 to rotate excessive; Adjust the initial position that bolt is used to adjust H shape connecting link 4 and connects straight-bar 5, make it slightly downward-sloping, prevent that it from moving upward, but it is excessive to be unlikely to tensile force f 2; Guard bar 7 can stop H shape connecting link 4 and upwards rotation of connection straight-bar 5 in process of the test, plays a protective role; The R10 mounting hole is used for the fixing of load protection drag-line, prevents to run behind the test load bump.
