Embodiment 1
[0038] The working ladder provided by Embodiment 1 includes a fixed rod 2 , a first support shaft 5 , a first support shaft seat 6 and a first movable rod 7 .
[0039] The upper end of the fixed rod 2 is fixed to the equipment body of the movable mechanical equipment. When it is applied on the pump truck, it is fixed to the body of the pump truck; for the convenience of installation, a fixed connecting piece can be set on the upper end of the fixed rod 2, such as: A connecting plate 1 is arranged on the upper end of the fixed rod 2, so that the connecting plate 1 is fixed to the upper end of the fixed rod 2 in the vertical direction, and a connecting hole is set on the part extending from the connecting plate 1. Usually, the connecting plate 1 is made to be uniform in order to be stressed. It extends to both sides of the working ladder, and symmetrical connecting holes are arranged on both sides of the connecting plate 1 . Same as the prior art, according to the needs of actua...

The invention relates to a working ladder and movable mechanical equipment comprising the working ladder. The disclosed working ladder comprises a fixed rod and a first movable rod, as well as a first support shaft seat and a first support shaft, wherein a first chute penetrating two ends is formed on the first support shaft seat; the first end and the second end of the first support shaft seat are hinged with the lower end of the fixed rod and the first end of the first movable rod respectively; two hinge axle lines which are parallel relatively are formed at two ends of the first support shaft seat, and are positioned on the same side of the chute; and the first support shaft is matched with the first chute, and the length of the support shaft is more than that of the first chute. The height of the step of the first movable rod can be adjusted according to different working requirements, the height adjusting process can be completed only by selectively sliding the first support shaft along the first chute, and the working ladder is convenient to operate without requiring a dedicated drive mechanism, so that the use cost of the working ladder is reduced.
Description
technical field [0001] The present invention relates to a working ladder, and furthermore, the present invention also relates to a movable mechanical device comprising the working ladder. Background technique [0002] The traditional working ladder on the pump truck is generally a purely rigid working ladder, please refer to figure 1 , figure 1 It is a structural schematic diagram of a purely rigid working ladder in the prior art. The pump truck has supporting legs, and the pump truck can be switched between the driving state and the working state by changing the state of the supporting legs; in the driving state, to ensure the driving performance of the pump truck, the lowest step 11 of the working ladder must There is a sufficient distance between the ground; in the working state, the supporting legs are propped up, so that the distance between the lowest step 11 of the working ladder and the ground increases, and this height often exceeds the scope of ergonomic requirem...
