Problems solved by technology

The leveling of traditional working platforms includes self-weight leveling, parallel four-bar linkage leveling, chain sprocket leveling, and hydrostatic leveling. They are only suitable for specific models and are not suitable for mass production, and there is no automatic detection device , when the structural aging occurs, the vehicle will be in a dangerous working state, which does not meet the requirements of intelligence and modularization

Embodiment Construction

[0014] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] refer to figure 1 ,Such as figure 1 As shown, the inclination sensor 11 detects the inclination angle of the working platform of the hanging basket, wherein the inclination sensor can be three kinds of inclination sensors of the "solid pendulum" type, the "liquid pendulum" type and the "gas pendulum" type; If the angle is greater than the angle set by the forward tilt sensor, the tilt sensor will generate a corresponding current signal according to the actually detected deviation angle and send it to the controller 12, wherein the deviation angle is proportional to the current signal produced by the sensor; the controller 12 uses The PID control algorithm performs calculations, outputs PWM (pulse width modulation control) ...

Abstract

The invention discloses a hanging basket levelling control system, comprising an electromagnetic proportion reverse valve, an inclination sensor, a controller and an oil cylinder. The inclination sensor is used for detecting the inclination of a working platform; the controller is used for receiving a signal sent out by the inclination sensor and converting the signal of the inclination sensor into an electromagnetic reverse signal; and the oil cylinder is used for supplying a power source of oil liquid and adjusting the inclination of a hanging basket. The handing basket levelling control system which adopts the PID (Proportion Integration Differentiation) control algorithm and is based on the electro-hydraulic proportional leveling principle has low cost, good continuity, tranquility and levelling properties, high control precision and fast dynamic response, and is suitable for various high altitude overhead working trunks.

Description

technical field [0001] The invention relates to the field of automatic leveling of work platforms, in particular to a leveling control system for a hanging basket. Background technique [0002] In recent years, with the rapid development of my country's economy, automatic leveling has been widely used in fire protection, rescue, construction, municipal administration, communications, electric power, ships, oil and gas production and other industries for construction, decoration, equipment installation and maintenance. The performance requirements for automatic leveling are also increasing. [0003] The leveling of the work platform has experienced the development process from self-weight leveling to electro-hydraulic integrated leveling. The leveling of traditional working platforms includes self-weight leveling, parallel four-bar linkage leveling, chain sprocket leveling, and hydrostatic leveling. They are only suitable for specific models and are not suitable for mass prod...
