Description

Bidirectional folding ramp

Technical Field

The utility model belongs to the technical field of interim slope, in particular to two-way foldable slope.

Background

In daily life, steps are visible everywhere, and the entrance of a building gate, the junction of a roadway and a sidewalk and the like have shadows. When people ride or use the handcart to carry goods, the people can not pass smoothly when encountering steps, thus causing passing or transportation obstacles. In this case, a temporary wood plate or iron plate is often required to be erected to form a ramp, but the passing or transportation efficiency is often affected because a proper material cannot be found in a short time; the temporarily built ramp is not always reinforced, is easy to slip off or tilt, and has certain potential safety hazard; if adopt portable design ramp, there are the processing cost higher, the dead weight is great, shortcoming such as inconvenient accomodating.

In the preferred scheme, one end of the longitudinal support rod is provided with an anti-slip sheet, and the anti-slip sheet is positioned on one side opposite to the fixed hinge support.

This patent can reach following beneficial effect:

1. the slope surface only consists of 2 structural components of a fixed hinged support and a folding frame, and is fixed and connected through bolts, so that the structure is simple and the installation is convenient;

2. the folding leg is formed by connecting a support rod and a connecting rod through anchor bolts, all parts can flexibly rotate, and transverse folding is convenient.

3. The supporting rod and the connecting rod are both made of square steel tubes with high rigidity, and the free end of the supporting rod is provided with the anti-slip sheet, so that the stability of the folding frame in the use process is improved.

4. The folding frame is connected with the fixed hinge support through the high-strength bolt, so that the folding frame is convenient to fold longitudinally and is favorable for disassembling and maintaining the folding frame.

5. The slope formed by connecting the fixed hinged support and the folding frame is fixed on the step tread by adopting a high-strength bolt, so that the connection is firm, and the slope and the step are prevented from sliding.

6. When the slope ramp is not in use, the slope ramp is in a folded state and is vertically placed on the step kick surface, and when the slope ramp is in use, the slope ramp is unfolded to provide traffic or transportation requirements.

Detailed Description

A preferred scheme is as shown in fig. 1 to 4, a bidirectional folding ramp comprises a folding frame 2, wherein one end of the folding frame 2 is hinged with a fixed hinge support 1; the folding frame 2 comprises two longitudinal support rods 5, a plurality of transverse connecting step rods 6 are arranged between the two longitudinal support rods 5, and the transverse connecting step rods 6 are hinged with the longitudinal support rods 5. The fixed hinged support 1 is hinged with a connecting piece 9 through a bolt 4, and the connecting piece 9 is fixed with a longitudinal support rod 5 positioned at the end part. The fixed hinged support 1 is provided with a plurality of bolt holes, high-strength bolts 3 penetrate through the bolt holes, and the high-strength bolts 3 are used for being fixed with the step skirting. The transverse connecting step rod 6 and the longitudinal support rod 5 are of a square steel pipe structure, and the transverse connecting step rod 6 and the longitudinal support rod 5 are hinged through anchor bolts 7.

And one end of the longitudinal support rod 5 is provided with an anti-skid sheet 8, and the anti-skid sheet 8 is positioned on the opposite side of the fixed hinge support 1.
