Description
Technical field
The present invention relates to a kind of level(l)ing device, relate in particular to a kind of full-automatic horizontal adjusting device based on liquid level sensor.
Background technology
Many equipment all needed to be fixed on earlier a certain ad-hoc location before using, again it is carried out horizontal adjustment, to guarantee the precision and the efficient of equipment work.At present, the general horizontal level that uses near the foreign object of close equipment support or install equipment carries out manual adjustments, but this mode degree of regulation is poor, and efficient is not high.Particularly for bulky heavy machinery, such as ram engine, pile press machine, regulate difficulty more, control accuracy is difficult to guarantee.
Summary of the invention
The present invention seeks to defective, a kind of precision height is provided, the full-automatic horizontal adjusting device that efficient is high based on liquid level sensor control at the existence of existing level conditioning equipment.
The objective of the invention is to be achieved through the following technical solutions: it comprises and is installed in four containers that four jiaos of level tables are used for contain fluid respectively, four liquid containers are installed in the four platforms post top portion respectively, the liquid container inwall is equipped with liquid level sensor, the liquid level sensor output terminal is connected with data acquisition module input end reason, the data acquisition module output terminal is connected with PLC Programmable Logic Controller input end, PLC Programmable Logic Controller output terminal is connected with the servomotor input end, the servomotor output terminal is connected with the hydraulic oil pump input end, and hydraulic oil pump and hydraulic reservoir and the hydraulic cylinder that is positioned at studdle are connected; The four platforms pillar is evenly distributed on four angles of level table, and hydraulic cylinder is nested in horizontal stand pillar inside, can move up and down.
The structure optimization staircase structural model of described liquid container, because the staircase structural model liquid container takes place when crooked at level table, the Level Change of liquid level is bigger in the container, the measurement sensitivity that can improve liquid level sensor.
Liquid level sensor preferred pressure type liquid level sensor, because the pressure-type liquid level sensor is simple in structure, reliable operation.
The liquid that holds in the liquid container is preferably anti freezing solution (promptly being added with the liquid of freeze-point depressant), with assurance device normal use at low temperatures.
When level table takes place when crooked, liquid level position changes thereupon, liquid level sensor is converted into electric signal input data acquisition module with the position signalling of liquid level, described data acquisition module reads in back input PLC Programmable Logic Controller with the liquid level data of collecting, store predefined liquid level position data in the PLC Programmable Logic Controller, the four groups of liquid level position data that described PLC Programmable Logic Controller will collect and the liquid level position data of setting compare, to determine operational stroke signal to four horizontal important actors, and with last result with the instruction form send to servomotor, servomotor is by the pressure of control hydraulic pump, control is positioned at the lifting of studdle hydraulic cylinder, thereby realizes the adjusting to the level table levelness.
The present invention can regulate the levelness of controlling level table top real-time automatically, and the control accuracy height.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is an automatic level adjusting device structure table top schematic top plan view.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises and is installed in four step liquid containers 2 that 6 four jiaos of level tables are used for contain fluid 3 respectively, four step liquid containers 2 are installed in four platforms pillar 4 tops respectively, step liquid container 2 inwalls are equipped with pressure-type liquid level sensor 1, pressure-type liquid level sensor 1 output terminal is connected with data acquisition module 11 input ends, data acquisition module 11 output terminals are connected with PLC Programmable Logic Controller 8 input ends, PLC Programmable Logic Controller 8 output terminals are connected with servomotor 9 input ends, servomotor 9 output terminals are connected with hydraulic oil pump 5, and hydraulic oil pump 5 and hydraulic reservoir 7 and the hydraulic cylinder 10 that is positioned at horizontal stand pillar 4 are connected; Described four horizontal stand pillars 4 are evenly distributed on four angles of level table 6, and hydraulic cylinder 10 is nested in horizontal stand pillar 4 inside, can move up and down the levelness that can regulate level table 6 by the height at controlling level table top 6 each angles.
The ledge structure of described step liquid container 2 can guarantee level table 6 when generation is crooked, and the change of the interior liquid level of container is bigger, the measurement sensitivity that can improve pressure-type liquid level sensor 1.
When level table 6 generations are crooked, the antifreezing liquid 3 that is contained in the step-type container 2 takes place to flow, liquid level position changes, liquid level sensor 1 is converted into the liquid level position signal in the electric signal input data acquisition module 11, four liquid level position data that data acquisition module 11 will be collected are read in back input PLC Programmable Logic Controller 8, PLC Programmable Logic Controller 8 internal memories contain predefined liquid level position data, this PLC Programmable Logic Controller 8 compares analysis with the liquid level position data of collection and the liquid level position data of setting, draw the signal that to operate four horizontal stand pillars, and with the instruction form net result is issued servomotor 9, servomotor 9 drives the lifting that hydraulic pump 5 controls are positioned at horizontal stand pillar 4, the final adjustment that realizes level table 6 levelnesss.
The present invention can avoid the armstrong's patent formula to regulate the shortcoming of level table 6 levelnesss, adopts the levelness of regulating level table 6 automatically by level change in the step-type container 2 real-time based on the control system of pressure type liquid level sensor, the control accuracy height; In addition, in the liquid that indicates level table 6 degree of tilt, add freeze-point depressant, help guaranteeing that this installs operate as normal at low temperatures.
