Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with accompanying drawing:
[0028] Such as figure 1 , figure 2 , image 3 and Figure 4 The shown folding escalator includes an escalator box 1 and a plurality of pedals 5, and each pedal 5 is hinged on the escalator box 1 through a main hinge shaft 4. The escalator box 1 of this embodiment includes a box bottom plate 1-2 and a The two side plates on both sides of the box bottom plate 1-2 are the box side plate 1-1 and the box side plate 1-3 respectively; each pedal 5 is provided with a secondary hinge shaft 61 on the outside of the main hinge shaft 4 And through this auxiliary hinge shaft 61 and connecting plate 6 hinged, each connecting plate 6 is provided with a plurality of arc-shaped openings that clamp the main hinge shaft 4 at intervals near the side of the main hinge shaft, as Figure 12 Shown; One of them in the multi-block pedal 5 is the main pedal 3, the main pedal 3 of the p...

The invention discloses a folding type staircase which comprises step plates hinged to a staircase box through main hinged shafts. One of the multiple step plates is a main step plate, the main hingedshaft on the main step plate is sleeved with a toothed plate through a toothed plate reset spring, and a cutter plate is arranged on the inner side of the corresponding main hinged shaft and hinged to the position, near the toothed plate, of the main step plate through a cutter plate reset spring, wherein a first hinge pin is sleeved with the cutter plate reset spring. The cutter plate is provided with a pawl part movably clamped to the toothed plate and a rocking handle part extending outside the main step plate, and the main step plate is provided with a first limiting pin in the connectingedge position of the pawl part and the rocking handle part. The staircase box is provided with a cam below the rocking handle part, the cam drives the rocking handle part to rotate, the staircase boxis provided with a second limiting pin in the position near the cam, and another second limiting pin is arranged below the first limiting pin. Each connecting plate is provided with multiple arc-shaped notches at intervals in the side edge near the main hinged shafts, wherein the arc-shaped notches are used for clamping the main hinged shafts. Compared with the prior art, the folding type staircase can solve the problem that a staircase of an existing engineering mechanical vehicle is likely to be bumped and thus deformed and damaged when making a turn in a narrow space.
Description
technical field [0001] The invention relates to the technical field of manufacturing engineering machinery vehicles, in particular to a folding escalator for engineering machinery vehicles. Background technique [0002] The escalator on the driver's cab of the existing construction machinery vehicle all comprises an escalator box and a plurality of pedals, and the plurality of pedals are fixedly mounted on the escalator box; the escalator box is installed on the vehicle frame near the cab door. . This kind of escalator has the following problems during use: because the escalator is on the outermost side of the turning vehicle, when the vehicle is turning in a narrow space, it is easy to be deformed and damaged by bumps; The raised sludge is splashed on the escalator, and the sludge accumulates, which affects the driver's access to and from the cab. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a folding escal...
