Problems solved by technology

[0002] The mobile platform is the carrier of the robot. At present, the mobile platform usually adopts electric drive mode. For example, the foreign Meidensha and the domestic Xinsong mobile platforms are all driven by motors. The mobile platform has better manipulation and control performance, but most of them are only suitable for indoor environments. Work, the universality is poor, and the moving speed is low, the mobility and off-road performance and the load-carrying traction capacity are insufficient, and it is not suitable for high-speed and heavy-load working conditions

Abstract

The invention relates to an energy-saving robot hydraulic movable platform. The energy-saving robot hydraulic moving platform mainly comprises wheels, a platform body, an electromagnetic brake, a steering mechanism, a secondary adjusting hydraulic driving device and the like, wherein the steering mechanism is a parallel four-bar steering mechanism, and the telescopic length of a piston rod of a steering oil cylinder is controlled by adjusting the input current of a proportional reversing valve to realize platform steering; the secondary element is connected with the rear drive axle, the platform is driven to move or recovers braking kinetic energy and slope gravity energy of the platform by adjusting the secondary element to be in the working condition of the hydraulic motor or the hydraulic pump respectively, and the braking kinetic energy and the slope gravity energy are converted into hydraulic energy to be stored in the energy accumulator and are used for starting, accelerating andclimbing movement of the movable platform. The energy-saving robot hydraulic movable platform is suitable for working under the working conditions of field, high speed and large load, and the movableplatform is large in bearing capacity and strong in traction capacity; and energy recovery and reutilization can be realized, and the installed power of the movable platform is greatly reduced.

Description

technical field [0001] The invention relates to a robot mobile platform, in particular to an energy-saving robot hydraulic mobile platform. Background technique [0002] The mobile platform is the carrier of the robot. At present, the mobile platform usually adopts electric drive mode. For example, the foreign Meidensha and the domestic Xinsong mobile platforms are all driven by motors. The mobile platform has better manipulation and control performance, but most of them are only suitable for indoor environments. Work, the universality is poor, and the moving speed is low, the mobility off-road and the load-carrying traction capacity are insufficient, so it is not suitable for high-speed and heavy-load working conditions. [0003] Hydraulic transmission has been widely used in the engineering field due to its advantages of stable transmission, convenient speed regulation, large power-to-mass ratio, and strong load-bearing traction capacity, and has become one of the importan...
