Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 2, the embodiment discloses a novel safe ladder stand of dish mouth formula scaffold, including two ladder beams 1 that the slope set up, be provided with a plurality of cat ladder footboard 2 between two ladder beams 1, the left and right terminal surface of cat ladder footboard 2 all is provided with two screw holes 201, and screw hole 201 passes through the bolt and is connected with corresponding ladder beam 1, and the upper and lower end of two ladder beams 1 all pegs graft with corresponding horizontal frame 3, as shown in fig. 3, horizontal frame 3 is the U-shaped. The top surface of the horizontal frame 3 is welded with an extension pedal 4, the outer side of the horizontal frame 3 is connected with a bottom plate 5 through bolts, and the bottom plate 5 is welded with a connecting piece 501. Connecting piece 501 adopts couple or knot to connect, and when the cat ladder was put at scaffold frame middle part position, connecting piece 501 can adopt the couple, and the couple articulates with the horizontal pole of scaffold frame. The hook and the buckle joint are respectively welded with different bottom plates 5 into an integral structure and are selected according to use requirements. When the ladder is at the side of the scaffold, the connector 501 may be a snap connector that is fastened to a connection pad on the riser. It should be noted that the hook and the buckle joint both belong to the prior art, and in this embodiment, a hook form is adopted.

In this embodiment, the ladder board 2 and the extension board 4 are both provided with anti-skid lines.

As shown in fig. 1 and 4, the upper end and the lower end of the ladder beam 1 are both provided with vertical rods 6, the two vertical rods 6 are connected through an inclined handrail rod 7, two ends of the inclined handrail rod 7 are both connected with the vertical rods 6 through bolt components, a threaded rod 601 is welded at the lower end of each vertical rod 6, the diameter of the threaded rod 601 is smaller than that of each vertical rod 6, a shaft shoulder is formed at the connecting part of the two vertical rods 6, and the lower end of the threaded rod 601 penetrates through the ladder beam 1 and the horizontal frame 3 and then is in threaded connection with a. The vertical rod 6 and the handrail diagonal rod 7 form a guardrail of the ladder stand, and meanwhile, the threaded rod 601 at the lower end of the vertical rod 6 can also play a role in fixing the ladder beam 1 and the horizontal frame 3.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
