In figure, 1 is ladder, and 1-1 is lateral rectangular tube, and 1-2 is longitudinal rectangular tube, and 1-3 is ladder extension device, and 2 be anchoring
Part, 3 be cover plate for manhole, and 3-1 is outline border, and 3-2 is inside casing, and 3-3 is hinge, and 3-4 is air-leg, and 3-5 is ladder connector, and 4 are
Template system, 5 be operating platform.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of large form ladder and cover plate for manhole, including ladder 1, climbs
Terraced anchoring piece 2, cover plate for manhole 3.Ladder 1 includes that transverse direction rectangular tube 1-1 and the longitudinal direction bottom rectangular tube 1-2, longitudinal rectangular tube 1-2 are set
There is ladder extension device 1-3, can be used to adjust ladder height.Longitudinal rectangular tube 1-2 and ladder extension device 1-3 are equipped with aperture, Gu
Timing can be aligned hole location and use is bolted.Ladder anchoring piece 2 is designed according to the actual size of ladder 1, is allowed to preferably solid
It is scheduled in template 4.Outline border 3-1 is made of four angle steel, and aperture and platform 5 overlap on angle steel, and outline border 3-1 inner wall quadrangle is all welded
