Description
Technical field
The present invention relates to a kind of job platform level-regulating system regulating based on gravity.
Background technology
At present, the leveling system of engineering field is mainly divided into two large classes: manual leveling system and automatic horizontal control system.Automatic horizontal control system can be divided into two large classes according to the topworks's difference adopting again: electromechanical automatic leveling system and fluid pressure type automatic horizontal control system.Manual leveling system mainly adopts range estimation and manual mode to carry out roughly leveling, or adopts other supplementary means to carry out secondary adjustment, and the leveling time is long, and precision is low, and distortion is large, and repeatability is large, and stability is not high; Electromechanical automatic leveling system adopts the topworks of ball screw as leveling more, and be combined with supporting leg support of the composition such as speed reduction unit, photoelectric encoder, servomotor, but the load-bearing capacity of ball screw is not strong, the driving force of system is less, therefore be not suitable for heavy mobile vehicle, be only applicable to the lighter mobile vehicle of load; Fluid pressure type automatic horizontal control system, mainly using hydraulic cylinder as executive component, adopts hydraulic-driven, and the driving force of this system is large, and load capacity is strong, but because the speed displacement of hydraulic cylinder is fed back relative complex, the realization of automatically controlling is more difficult.
Summary of the invention
The object of this invention is to provide a kind of driving force large, load capacity is strong, and the leveling time is short, be out of shape little, repeatability little, stability high based on gravity regulate job platform level-regulating system.
The object of the invention is to be achieved through the following technical solutions: a kind of job platform level-regulating system regulating based on gravity, comprises main frame, ECU, Ultronics control system, front left support oil cylinder, front right support oil cylinder, rear left support oil cylinder, rear right support oil cylinder, degree of tilt pick-up unit, described main frame by data line respectively with ECU, Ultronics control system is connected, and described Ultronics control system is hydraulic control system, is connected with ECU by data line, described Ultronics control system by oil circuit respectively with front left support oil cylinder, front right support oil cylinder, rear left support oil cylinder, rear right support oil cylinder is connected, described front left support oil cylinder, front right support oil cylinder, rear left support oil cylinder, rear right support oil cylinder inwall is separately installed with pressure transducer, described pressure transducer is connected with ECU by signal wire respectively, described degree of tilt pick-up unit is fixed on job platform by screw rod, inside is provided with circular trough, ball is placed in circular trough, described circular trough bottom surrounding and front left support oil cylinder, front right support oil cylinder, rear left support oil cylinder, rear right support oil cylinder opposite position is equipped with respectively pressure transducer
, pressure transducer
, pressure transducer
, pressure transducer
, pressure transducer is equipped with in bottom centre
, described pressure transducer
11, pressure transducer
, pressure transducer
, pressure transducer
, pressure transducer
be connected with ECU by signal wire respectively.
Described main frame is microcomputer.
Described ECU is electronic control unit, claims again " car running computer ", " vehicle-mounted computer " etc.Be automobile specified microcomputerized controller from purposes at present, be also automobile specified single-chip microcomputer.It is the same with common single-chip microcomputer, is made up of large scale integrated circuits such as microprocessor (CPU), storer (ROM, RAM), input/output interface (I/O), analog to digital converter (A/D) and shaping, drivings.The function of ECU (Electrical Control Unit) is that the information of air mass flow being taken into account to various sensors inputs according to the program of its internal memory and data is carried out computing, processing, judgement, and then output order provides the electric impulse signal of certain width to control distributive value to fuel injector.ECU (Electrical Control Unit) is made up of microcomputer, input, output and control circuit etc.
Described Ultronics control system is hydraulic control system, its key at multiple directional control valve in its unique double spool control technology, every plate valve has two spools, be equivalent to a three-position four-way valve to become the combination of two three-position three-way valves, two spools both can be controlled separately, also can control in pairs according to steering logic, and two actuator ports have pressure transducer, each spool position sensor, by to the closed-loop control of transducing signal, the pressure to two-way hydraulic oil or flow are controlled respectively, there is very high control accuracy, multiple directional control valve can obtain various control programs by different combinations, to meet the needs of system.
Thereby the present invention mainly utilizes ball gravity to judge the horizontal situation of platform inclination state adjustment job platform, adopts hydraulic-driven, and driving force is large, and load capacity is strong, can realize preferably automatic leveling control procedure.
