Abstract
The utility model discloses a four-corner leveling control system of a hydraulic support test platform. The four-corner leveling control system of the hydraulic support test platform is characterized in that the four-corner leveling control system of the hydraulic support test platform comprises four plunger type cylinders fixed onto a hydraulic press lower cross beam, position sensors installed on the plunger type cylinders, a leveling controller, servo valves and a PID controller. Analogue output units of the position sensors are connected with analog input units of the leveling controller. An instruction output port of the leveling controller is connected with an instruction input port of the PID controller. The PID controller, the servo valves and the plunger type cylinders are sequentially connected. The four-corner leveling control system of the hydraulic support test platform realizes the function that the large-tonnage hydraulic support test platform is perpendicular to an external load, has the leveling function, and greatly improves the work efficiency.
Description
Technical field
The utility model belongs to the hydropress technical field, is specifically related to a kind of four-corner leveling control system of hydraulic support test platform.
Background technology
In recent years, flourish along with coal industry, hydraulic support has obtained using more and more widely, therefore people are to the security performance of hydraulic support and the gradually harshness of wanting changes persuing of technical feature, the hydraulic bracket test-bed key equipment that detects these performances as test, therefore, hydraulic bracket test-bed technology also becomes the emphasis of research.The at present hydraulic bracket test-bed interior loading that mainly is applicable to both domestic and external, and the large-tonnage testing table still lacks the ability that vertical external carries, because the large-tonnage testing table need adopt the multi-cylinder vertical external to carry programme of work, so the large-tonnage testing table has just related to the problem of multi-cylinder synchronous, therefore developing a kind of four-corner leveling control system that is applicable to the large-tonnage testing table seems particularly important.
Summary of the invention
The technical problems to be solved in the utility model is that existing hydraulic support leveling system is improved, propose a kind of powerful, offset loading force is little, the four-corner leveling control system of the hydraulic support test platform of high efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of four-corner leveling control system of hydraulic support test platform is characterized in that: comprising: be fixed in four plunger cases on the hydropress sill, be installed on position transducer, leveling controller, servo-valve and PID controller on the described plunger case; The analog output unit of described position transducer is connected with the analog input unit of described leveling controller, the instruction output end mouth of described leveling controller is connected with the instruction input port of described PID controller, and described PID controller, described servo-valve and the plunger case of being connected connect successively.
As preferred version, the utility model has also adopted following technical characterictic:
Described four plunger cases evenly are fixed on four angles on the hydropress sill;
Described plunger case is the axial columns plug cylinder.
Advantage and the good effect that the utlity model has are: one, powerful, by adopting the four-corner leveling control system, the utility model both can have been realized great tonnage hydraulic stented test platform vertical external loading function, had again levelling function simultaneously; Two, by adopting position transducer, realize the accurate Real-Time Monitoring of plunger case inner carrier position, improved the precision of system; Three, by adopting position transducer, leveling controller and PID controller, robotization and the intellectuality of system have been realized.
Description of drawings
Fig. 1 is the structure principle chart of the four-corner leveling control system of a kind of hydraulic support test platform of the utility model.
Among the figure: 1, position transducer; 2, plunger case; 3, hydropress sill; 4, servo-valve; 5, PID controller; 6, leveling controller.
Embodiment
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Fig. 1 is structure principle chart of the present utility model, a kind of four-corner leveling control system of hydraulic support test platform comprises: be fixed in four plunger cases 2 on the hydropress sill 3, be installed on position transducer 1, leveling controller 6, servo-valve 4 and PID controller 5 on the described plunger case 2; The analog output unit of described position transducer 1 is connected with the analog input unit of described leveling controller 6, the instruction output end mouth of described leveling controller 6 is connected with the instruction input port of described PID controller 5, and described PID controller 5, described servo-valve 4 and the plunger case 2 of being connected connect successively.Described four plunger cases 2 evenly are fixed on four angles on the hydropress sill 3; Described plunger case 2 is the axial columns plug cylinder.
Specific works principle of the present utility model is: four plunger cases 2 play hydraulic bracket test-bed vertical external loading function on the one hand, in addition on the one hand, be installed on position transducer 1 on the plunger case 2 with the movement position Real-Time Monitoring of plunger case 2 inner carriers and be transferred to leveling controller 6, leveling controller 6 averages computing with the piston position of four plunger cases 2, and will surpass preset range with the distance of average value difference the time, leveling controller 6 is by Control PID controller 5, PID controller 5 and then the oil transportation direction by controlling corresponding servo-valve 4 and oil transportation amount realize the adjustment to the duty of respective post plug cylinder 2, realize the function of leveling.
More than a kind of embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
