Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: described static load mechanical strength testing machine of flexible heating apparatus mainly is comprised of frame 1, roller parts, towing plate 9, walking driving mechanism and supporting electric cabinet.
As shown in Figure 1 and Figure 2, described frame 1 top is provided with the platen 4 for the detected product of lay, and the roller parts that are used for applying static load to detected product are being set above platen 4; Described roller parts are by two towing plates, 9 supportings of platen 4 both sides, the roller parts comprise bolster 10 and roller 11, roller 11 is contained on bolster 10 by bearing holder (housing, cover), roller 11 a plurality of rubber hemisphere 12 of the upper rules distribution in surface, bolster 10 two supports are on towing plate 9, towing plate 9 lower ends are connected on the walking driving mechanism, and roller parts and towing plate 9 drive by the walking driving mechanism, and along continuous straight runs is movably walking.
Because may there be irregular phenomenon in the surface that is detected product (flexible heating device), so roller need to have certain distance of moving about at above-below direction, can walking smoothly on detected product surface to guarantee it.Based on this reason, the present invention is provided with the capable support slot 9a of U of upper end open in towing plate 9 upper ends, and bolster 10 two supports also can move up and down in the capable support slot 9a of U.
