Abstract

The utility model relates to a convenient step ladder, which comprises a triangular frame, a ladder stand, protective barriers and a supporting mechanism. The bottom surface of the triangular frame is rectangular, two opposite side surfaces of the triangular frame are right-angled triangles, the ladder stand is fixed on an inclined surface at the top end of the triangular frame, the protective barriers are fixed at the periphery of the ladder stand, and the supporting mechanism is arranged at the bottom end of the triangular frame. The convenient step ladder is reasonable in structural design and flexible and convenient in use, effectively saves operation time and increases work efficiency.

Description

The portable ladder of ascending a height

Technical field

The utility model relates to a kind of climbing equipment, particularly relates to a kind of portable ladder of ascending a height.

Background technology

At present, in the heavy-duty machinery processing industry, the ladder of ascending a height that lathe is used, structure is too fat to move, and rigidity is relatively poor, and easy deformation; Ladder generally is immovable, need utilize overhead traveling crane when mobile; Tread is the plank of edge, relatively pine and come off easily or tramp; When ground was uneven, ladder was put also not steady, such ladder, used very inconveniently, and need take valuable overhead traveling crane resource when mobile, not only lost time, and also had potential safety hazard.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, the portable easy to use ladder of ascending a height.

In order to address the above problem, the utility model by the following technical solutions:

The portable ladder of ascending a height, comprise triangle-frame, cat ladder, protective guard and supporting mechanism, the bottom surface of triangle-frame is a rectangle, wherein two relative sides are right-angled triangle, cat ladder is fixed on the inclined-plane on triangle-frame top, be fixed with protective guard around the cat ladder, the triangle-frame bottom is provided with supporting mechanism.

Described supporting mechanism comprises bracing frame, roller and adjusting bolt, and four jiaos of the triangle-frame bottom are fixed with bracing frame respectively, and roller is installed in the bracing frame bottom, and welding hold-down nut in bracing frame side is regulated bolts and nuts and is connected.

Described adjusting bolt head is regulated the bolt top stubborn bar is installed down.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model reasonable in design, good stability need not to use overhead traveling crane, thereby has saved the working time when mobile, improved operating efficiency.

2, the utility model supporting mechanism adopts roller and regulates the mode that bolt combines, and when needs moved, four-wheel landed and can push away away; Do not need when mobile, bolt lands and gets final product, and regulates the balance that bolt can be adjusted whole cat ladder according to the situation on ground, easy to use flexibly.

Fig. 3 is the utility model supporting mechanism structural representation.

The specific embodiment

The portable ladder of ascending a height, as shown in Figure 1 and Figure 2, comprise triangle-frame 2, cat ladder 3, protective guard 4 and supporting mechanism 1, the bottom surface of triangle-frame 2 is a rectangle, wherein two relative sides are right-angled triangle, cat ladder 3 is fixed on the inclined-plane on triangle-frame 2 tops, is fixed with protective guard 4 around the cat ladder 3, and triangle-frame 2 bottoms are provided with supporting mechanism 1.As shown in Figure 3, supporting mechanism 1 comprises bracing frame 5, roller 9 and regulates bolt 7, four jiaos of triangle-frame 2 bottoms are fixed with bracing frame 5 respectively, roller 9 is installed in bracing frame 5 bottoms, bracing frame 5 sides welding hold-down nut 8, regulate bolt 7 and be connected, regulate bolt 7 heads down, regulate bolt 7 tops stubborn bar 6 is installed with nut 8.

In the time of need ascending a height climbing, roller 9 of the present utility model is landed, shift the operating position onto, will regulate bolt 7 then and land, bar 6 is twisted in rotation according to surface state, and with the leveling of the utility model framework, the hand steered protective guard 4 of staff is climbed up cat ladder 3 and got final product.

Claims
