Abstract

The invention relates to the technical field of lifting machinery, in particular to a steering mechanism, a work platform chassis and a scissor-fork type aerial work platform thereof. The steering mechanism comprises walking wheel assemblies, a connecting cross rod and an actuator. The walking wheel assemblies can be in pivot connection with a chassis frame of the work platform. The two ends of the connecting cross rod are in pivot connection with the walking wheel assemblies located at the two transverse ends of the chassis frame correspondingly. The actuator comprises a fixed end and a movable end, the fixed end is arranged on the chassis frame and arranged in the transverse direction, and therefore the movable end can only stretch out and draw back linearly in the transverse direction. In the steering mechanism, the actuator is arranged in the transverse direction, so that the movable end linearly stretches out and draws back in the transverse direction all the time, larger steering driving torque and smaller steering resisting torque can be generated, and the steering mechanism is more beneficial to steering.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a steering mechanism, a working platform chassis and a scissor-type high-altitude working platform. Background technique [0002] figure 1 It is a perspective view of an existing steering mechanism. Such as figure 1 As shown, in the existing steering mechanism, both ends of the actuator 30 are pivotally connected to the road wheel assembly 10 and the connecting cross bar 20 respectively, and the actuator 30 drives the connecting cross bar 20 in the form of a brace. Since there is a relatively large angle between the actuator 30 and the connecting crossbar 20, the force generated by the actuator 30 is dispersed, which is not conducive to steering. Contents of the invention [0003] In view of the above defects or deficiencies in the prior art, the present invention provides a steering mechanism, a working platform chassis and a scissor-type aerial work platform the...
