The ladder step plate is formed by bending four sides of a 3 mm-thick antiskid pattern steel plate or a 1.5 mm-thick bidirectional punching steel plate at right angles.
And the upper top plate and the lower top plate are provided with connecting holes fixed with the bottom frame or the top frame.
The left side beam and the right side beam are formed by bending two sides of a 3mm thick steel plate at right angles, and welding grooves for welding the step plates are formed in the bent angle edges of the left side beam and the right side beam.
Offer the bolt hole that is used for fixed stair railing on the handrail sleeve, the inclination that is used for the unit stair of safety ladder cage and underframe is 35 ~ 45.
The utility model provides an existing defect among the background art, have following beneficial effect:
a unit stair for safe ladder cage, solved the inconvenient problem of current stair railing dismouting, and stair intensity is high, the security is good. The utility model discloses a set up the handrail sleeve outside the left side roof beam, plug into the handrail sleeve with the stair railing to it is tight to push up with the tight bolt top, makes the stair railing dismouting comparatively convenient. The step board adopts anti-skidding decorative pattern steel sheet or the shaping of four sides bending of two-way steel sheet that punches a hole, bends through the quartic limit, on the one hand, has increased its step board's and the bulk strength of stair by a wide margin, has eliminated its potential safety hazard, and on the other hand, anti-skidding decorative pattern steel sheet has good frictional force, can eliminate the potential safety hazard that constructor skidded because of the step board and falls.

Detailed Description
Examples
As shown in figures 1 to 2, the unit stair for the safety ladder cage is connected between a bottom frame 9 and a top frame 10 of a ladder cage unit in an inclined 45-degree mode, comprises a frame which is enclosed by a left side beam 1, a right side beam 2, an upper top plate 3 at the upper part and a lower top plate 4 at the lower part, wherein the left side beam 1 and the right side beam 2 are horizontally welded with a plurality of ladder step plates 5, and the outer side of the left side beam 1 is welded with a handrail sleeve 7 for splicing a stair handrail 6. The ladder step plate 5 is formed by bending four sides of a 3 mm-thick anti-skid pattern steel plate or a 1.5 mm-thick bidirectional punching steel plate at right angles, and welding grooves used for welding the ladder step plate 5 are formed on the bent angle edges of the left side beam 1 and the right side beam 2. The upper top plate 3 and the lower top plate 4 are provided with connecting holes 8 fixed with the bottom frame 9 or the top frame 10. The left side beam 1 and the right side beam 2 are formed by bending two sides of a steel plate with the thickness of 3mm at right angles. Bolt holes for fixing the stair handrail 6 are formed in the handrail sleeve 7.
The utility model discloses a working process is: as shown in fig. 3 and 4, the left side member 1, the right side member 2, the upper roof panel 3, and the lower roof panel 4 are first welded as a frame, and then the step panels 5 are inserted into the welding grooves of the left side member 1 and the right side member 2 and are fully welded. And finally welding the armrest sleeve 7 outside the left side beam 1. When the unit stair is installed, the connecting holes 8 of the upper top plate 3 and the lower top plate 4 of the unit stair are aligned with the fixing holes on the top frame 10 and the bottom frame 9 and are fastened by bolts. Two ends of the stair handrail 6 are respectively inserted into the corresponding handrail sleeves 7 of the stair and are screwed into the connecting holes 8 to be tightly pressed. The utility model discloses a set up handrail sleeve 7 in the 1 outside of left side roof beam, peg graft handrail 6 in handrail sleeve 7 to it is tight with the tight bolt top in top, make 6 dismouting of handrail comparatively convenient. Step 5 adopts 3mm thick anti-skidding decorative pattern steel sheet or the shaping of four sides bending of 1.5mm two-way steel sheet that punches a hole, bends through the four sides, on the one hand, has increased its step 5's and the bulk strength of stair by a wide margin, has eliminated its potential safety hazard, and on the other hand, anti-skidding decorative pattern steel sheet has good frictional force, can eliminate the potential safety hazard that constructor skidded because of the step.
