Abstract

The invention belongs to the field of high-altitude operation, and in particular relates to a steering connection device which is applied to a straight-arm type high-altitude operation trolley and can drive an operating platform to perform three-dimensional rotation. The steering connection device comprises a connecting plate and a support arm which are perpendicular to each other, wherein a horizontal rotary oil cylinder and a vertical rotary oil cylinder are arranged on the connected plate; one side of the connecting plate is provided with an upper support plate and a lower support plate which are perpendicular to the connecting plate; the vertical rotary oil cylinder is positioned above the upper support plate and is vertically connected to the connecting plate; a rotary shaft of the horizontal rotary oil cylinder is vertically connected between the upper support plate and the lower support plate; one side, which backs on to the connecting plate, of the horizontal rotary oil cylinder is provided with a connecting frame; and a flexible oil cylinder is arranged in the support arm. The steering connection device is simple in structure, can perform three-dimensional rotation substantially and lift multiple platforms together, and can be applied to various complex work environments and professions.

Description

technical field [0001] The invention belongs to the field of high-altitude operation, and in particular relates to a steering connection device applied to a straight-arm type high-altitude operation vehicle and capable of driving an operation platform to perform three-dimensional rotation. Background technique [0002] Most of the operating platforms of existing aerial work vehicles can only perform rotation on one or two planes, and cannot perform three-dimensional rotation, so that a type of aerial work vehicle can only perform certain types of work in a targeted manner, with a small application range and low production capacity. The cost is high. Moreover, most of the steering systems of existing aerial work vehicles use electro-hydraulic steering systems. The electro-hydraulic steering system adds an electronic control device to the hydraulic power assist system to realize the integration of the vehicle's electronic control system. However, its steering transmission mech...
