Summary of the invention
The problem that we will solve is: overcome prior art defect, ensures construction safety.
The invention provides a kind of adjustable safety construction cat ladder, its structure has: ballast box 1, cantilever mounted column 2, cantilever ejector pin 3, cantilever mounted hanger 4, adjustable ladder locator 5, movable cantilever column 6, movable cantilever hanger 7, cantilever beams 8, safety belt hanging ring 9, cantilever support plate 10, adjustable ladder 2 11, cat ladder hinge 12, adjustable ladder 1, removable cat ladder support 14, cat ladder supports mounting yoke 15, mark time 16, safety belt 17; Adjustable ladder 2 11 is connected by cat ladder hinge 12 with adjustable ladder 1, and adjustable ladder locator 5 pairs of adjustable ladders 2 11 position; Described movable cantilever column 6, cantilever mounted column 2 connecting portion evenly open φ 15 ~ 25 pin-and-hole processed.
Using method is as follows:
A, the height of foundation site operation situation and the size of construction space, determine whether install movable cantilever column 6 and adjustable ladder 13;
B, movable cantilever column 6 is lifted in cantilever mounted column 2 endoporus; Utilize cantilever ejector pin 3 to regulate the height of movable cantilever column 6, determine position of positioning hole on cantilever mounted column 2;
C, cantilever ejector pin 3 assemble with movable cantilever column 6 and cantilever mounted column 2, screwde on nut;
D, adjustable ladder 1 are assemblied on ballast box 1, use removable cat ladder to support 14 and are fixed by adjustable ladder 1;
E, adjustable ladder 2 11 is lifted on adjustable ladder 1, uses cat ladder hinge 12 and adjustable ladder locator 5 that adjustable ladder 2 11 is fixed, is located; Confirm that adjustable ladder 2 11 assembles the assembling carrying out adjustable ladder 1 firmly again;
F, cantilever beams 8 is stretched into construction space;
The all parts of G, preoperation inspection, after guarantee cat ladder, fixation, constructor uses adjustable ladder 2 11, adjustable ladder 1 enters the operation of work high above the ground district;
H, safety belt 17 must to be hung on safety belt hanging ring 9 in whole work progress.
The invention has the beneficial effects as follows, constructor's personal safety can be ensured to the work high above the ground of various differing heights, different spaces, increase the radius of clean-up simultaneously, substantially increase utilization rate and the scope of application of cat ladder.The present invention adopts removable component, install, transport, use all convenient and swift, improve operating efficiency.
