Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of Multipurpose safety-belt fixed ladder-stool frame, for folding herringbone ladder, herringbone ladder by the symmetrical terraced leg 3 mutually supporting of mirror image and therebetween uniform whippletree 14 form, adopt hinge 2 to be hinged with top hinge plate 1 on the top of terraced leg, between this top hinge plate, be fixedly mounted with top rail 13.
Innovative point of the present invention is:
(1) between the lower margin of each terraced leg lower end, all level hinge fills the fixing sole 6 of a U-shaped, and this U-shaped is fixed sole outward opening, and by lower margin hinge 12 and terraced leg hinge dress, the fixing sole of this U-shaped also can be used as a ladder of step stool frame.The equal level in axis position between the fixing sole of two U-shapeds is installed a flexible leading screw 7, the outer end of these two flexible leading screws coaxially connects hinge dress with the fixing sole of U-shaped, inner end is all engaged and is arranged in a screw plate 8, realizes thus and rotates screw plate, i.e. lateral separation between adjustable terraced leg.Fixing two U-shapeds two made outside opening setting-ins of sole are entered on the channel-section steel of framework, can realize by rotating wire motherboard can by fixing the U-shaped of step stool frame sole securely setting-in enter the object of fixing step stool frame in the channel-section steel of both sides; On the top rail of ladder, can be hanging safety belt, to meet the associated safety standard of power domain.
(2) all fill a hinge plate 9 by lower margin hinge hinge in the outside, two lower ends of a side ladder leg, a hook 10 is installed by ingot fastening bolt 11 in the lower end of this hinge plate, on hinge plate, be shaped with an oval slotted hole, the relative displacement of adjustable hinge plate and hook, regulate the extension elongation of hook, and it is fastening to adopt ingot fastening bolt to position.
(3) all cut with scissors and fill a step stool assembly 4 in the same way at two terraced leg outer sides of phase the same side, this step stool assembly is referring to Fig. 3,4,5,6,7, formed by universal free bearing 15, step stool riding boogie board 17, step stool riser 19, the inner end of step stool riding boogie board is contained on terraced leg by universal free bearing hinge, the outer end of step stool riding boogie board is by hinge free bearing 18 hinge dress step stool risers, the lower end of step stool riser is shaped with the opening 20 with the fixing sole equidirectional of U-shaped, in the time of construction operation, the opening of the fixing sole of the opening of step stool riser and U-shaped can be inlaid on the channel-section steel of framework jointly.For step stool riser and the framework channel-section steel of being fixedly clamped, a worm screw 23 is installed on the bottom surface of step stool riding boogie board, one end of this worm screw is provided with a handgrip 16; Adopt junction plate 21 and universal free bearing hinge dress in the bottom surface position of step stool riding boogie board, the leading section of this junction plate fixedly mounts a worm gear 22 by bearing pin, and step stool riding boogie board hinge is contained on this bearing pin, worm gear and worm engaging.So, by the rotation of handgrip, worm engaging worm gear, because worm gear and junction plate are fixing, step stool riding boogie board is that hinge is contained on bearing pin, and therefore, the rotation of worm gear makes step stool riding boogie board taking bearing pin as the fan-shaped rotation of axle, can make thus the tight setting-in of the made opening of step stool riser be fixed on the channel-section steel of framework, reach fixing riding boogie board, the stable object of enhancing step stool frame.The setting of step stool riding boogie board, has also solved the problem of staff's working depth discomfort.
The universal free bearing of step stool assembly can make step stool riding boogie board realize the rotation of 180 degree, and step stool riding boogie board and step stool riser are hinge hinge dress, collapsible each other, can realize thus the folding laminating of step stool assembly on terraced leg, and can adopt bolt and rope to bind.
Step stool frame of the present invention is deployable, and two hooks of a side ladder leg can be mounted on fixture, form yi shaped ladder function; In addition, also collapsible and wiping positions with the reference column 5 between kicking, is convenient for carrying.
Installation between the each parts of the present invention all adopts bolt, connector riveting method.
