Abstract

The invention relates to a 3-RPS-based self-leveling foldable arm elevator. The 3-RPS-based self-leveling foldable arm elevator comprises a self-leveling device, a truck and a foldable arm elevator body, and is characterized in that the self-leveling device is mounted between a foldable arm and the truck, and three leveling support legs are uniformly arranged at 120 degrees on a movable platform and a static platform; an oil cylinder is hinged to the static platform, a bearing base d is in bolted connection with the oil cylinder, bearing bases are used in pairs, a support a is mounted on a through hole a, a bulged circular ring on the support a props against the movable platform, and a bearing base b is mounted on a through hole b; one end of a rod a and one end of a rod b are respectively in clearance fit with bearings mounted in the bearing bases, and the other end of the rod a and the other end of the rod b are hinged through a shaft. The elevator designed on the basis of 3-RPS solves the problem that a conventional elevator cannot work on a sloped or rugged pavement. In combination with many advantages of the foldable arm elevator, the designed elevator is stable in structure and easy to store, the working range of the elevator is expanded and the working efficiency is improved.

Description

technical field [0001] The invention relates to a 3-RPS-based self-leveling folding arm lift, belonging to the technical field of construction machinery. Background technique [0002] Elevator is a kind of aerial work machine that transports staff, tools and working materials to the target location for operation. According to the form of its lifting mechanism, it can be generally divided into four basic forms: telescopic arm type (straight arm type), folding arm type (curved arm type), vertical lift type and hybrid type. Among them, the folding arm lift is a very commonly used lift equipment. The maximum working gradient of conventional folding boom lifts is 7 degrees, and it is not suitable for road surfaces with slopes or undulations. my country is a mountainous country. The mountainous area accounts for more than 2 / 3 of the country's total land area, and the number of mountain towns accounts for nearly half of the total number of cities and towns in the country. The ter...
