Problems solved by technology

Modern leveling legs are mostly in the form of hydraulic cylinders, which cannot achieve precise control. At the same time, hydraulic cylinders need to be used in conjunction with hydraulic oil tanks and pump stations, which cannot achieve effective use of space. At the same time, hydraulic cylinders have related problems such as sealing

Abstract

The invention provides a high-precision planetary roller screw leveling supporting leg. The high-precision planetary roller screw leveling supporting leg comprises a ball head supporting leg, wherein the ball head supporting leg is rotatably mounted at the front end of a telescopic rod; the rear end of the telescopic rod is fixedly mounted on a roller screw set; the roller screw set is driven by a servo motor; and the telescopic rod is mounted in a supporting leg housing in a matched manner and moves along the supporting leg housing. According to the high-precision planetary roller screw leveling supporting leg disclosed by the invention, large-stroke precise control is realized by utilizing the integrated servo motor, so that the integral high-precision requirements can be effectively met; the mounting space is saved, the weight is integrally reduced, and the mounting flow is simplified; and purely electric control is utilized, so that the operation is simplified, the integral operation of a whole vehicle is facilitated, and the high-precision planetary roller screw leveling supporting leg has great assistance for equipment needing electrical control.

Description

technical field [0001] The invention relates to a high-precision planetary roller screw leveling support leg. Background technique [0002] Equipment such as cranes, aerial work vehicles, and elevating fire trucks are usually equipped with outriggers to ensure sufficient safety and stability during work, and to improve the safety factor of the entire vehicle when it is overturned. The outriggers are usually arranged on both sides of the bottom of the equipment chassis, and the number is usually four. When working, the outriggers are stretched, each outrigger lifts the whole equipment, and the tires are off the ground. The whole equipment is completely supported by the outriggers and the equipment site must be kept level to improve the anti-tipping ability of the equipment during operation. Modern leveling legs are mostly in the form of hydraulic cylinders, which cannot achieve precise control. At the same time, hydraulic cylinders need to be used in conjunction with hydraul...
