Description
Technical field
The present invention relates to a kind of safety control systems, and in particular to a kind of hot three weight of Combined Loading equipment of explosive power
Power security protection system and method.
Background technology
In the hot Combined Loading equipment of explosive power, high pressure load is to carry out structural strength and mechanical behavior point to Explosive Parts
The effective means of analysis.
But in high pressure loading procedure, due in face of be high energy, fire, the high-risk operations of high pressure, it is therefore desirable to adopt
With corresponding safety prevention measure.It is largely individually to press at present for the security protection of the hot Combined Loading equipment of explosive power
Power security protection, there are queries for protection dynamics and effect.
Invention content
An object of the present invention is to provide a kind of triple burden security protection system of the hot Combined Loading equipment of explosive power,
Integrate automatic measurement protection, automatic safeguarding and protection manually.
The invention is realized in this way：
A kind of hot Combined Loading equipment triple burden security protection system of explosive power, includes the mechanical-hydraulic on host
Switch, the measurement sensor on host oil cylinder and the safety sensor positioned at hydraulic station, measurement sensor, safety sensor
The operation and control to measurement data are realized by PLC.
In the present invention, mechanical-hydraulic switch is accomplished that manual protection；Measurement sensor and PLC compositions measuring loop, peace
Full sensor forms safety return circuit with PLC, and functionally mutually independent automatic protection is realized in double loop.
In the present invention, it can be worked normally if safety return circuit even if measuring loop breaks down.Even if there is event in safety return circuit
Barrier or accidental power failure, protection manually can also work normally, to improve the effect of security protection.
The present invention also provides a kind of hot Combined Loading equipment triple burden safety protecting methods of explosive power, including：
1) measuring loop automatic protection.Using independent measurement sensor carry out automatic measurement, by PLC according to setting value into
Row is automatic to be calculated, and when more than setting pressure 10%, PLC is automatically stopped underbeam action, is simultaneously emitted by sound-light alarm, computer
Upper display alarm content：Pressure limit 10%.
2) safety return circuit automatic protection.Using independent safety sensor carry out automatic measurement, by PLC according to setting value into
Row is automatic to be calculated, and when more than setting pressure 20%, automatically opens all relief valves, and stop hydraulic pump, equipment is with most quickly
Spend pressure release.It is simultaneously emitted by sound-light alarm, alarm content is shown on computer：Pressure limit 20%.
3) protection manually.It is carried out using manual mode.Using mechanical-hydraulic switch manual setting limit pressure, when more than pole
When limits pressure, direct pressure release oil return box.
The present invention is directed to high energy, fires, the high-risk operations of high pressure, provides a kind of triple burden security protection system, collection is certainly
Dynamic measurement protection, automatic safeguarding and manual protection are integrated.From triple guarantee security protections, when abnormal conditions occur,
People, machine security protection for the hot Combined Loading equipment of explosive power.
Description of the drawings
Fig. 1 is measurement sensor, safety sensor, mechanical-hydraulic switch distribution schematic diagram；
Fig. 2 is pressure automatic protection logic control schematic diagram；
Fig. 3 is the addresses pressure automatic protection PLC figure；
Fig. 4 is pressure automatic protection hardware elementary diagram.
Specific implementation mode
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
As shown in Fig. 1, the hot Combined Loading equipment triple burden security protection system of a kind of explosive power, including it is located at host
Mechanical-hydraulic switch 5 on 1 column 2, the measurement sensor 6 on host oil cylinder 3 and the safety sensing positioned at hydraulic station 4
Device 7, measurement sensor, safety sensor realize the operation and control to measurement data by PLC.
As shown in Fig. 2, the logic control of pressure automatic protection is realized by PLC.When measurement sensor measures current pressure values,
CPU is calculated automatically according to setting value, when judging superpressure 10%, logic relay M1.2 is made to be closed, is connect to the Q0.1 of PLC
It is logical.If measurement sensor fails, safety sensor measures current pressure values, and CPU calculates automatically according to setting value, when judging superpressure
When 20%, logic relay M1.4 is made to be closed, is connected to the Q0.2 of PLC.Meanwhile the normally-closed contact of M1.4 is opened, to PLC
Q0.3 open.It executes and acts in next step.
As shown in Fig. 3, it is the addresses pressure automatic protection PLC figure.Wherein, Q0.1 is sound-light alarm, and Q0.2 is automatic leakage
Pressure, Q0.3 hydraulic pumps.After the entry condition of sound-light alarm, releasing pressure automatically, hydraulic pump meets, it is respectively closed, to make centre
The coil of relay KA1, KA2, KA3 respectively it is electric, execute in next step act.
As shown in Fig. 4, it is pressure automatic protection hardware elementary diagram.When superpressure 10%, intermediate relay KA1 coils obtain
Electricity, normally opened contact are closed, and buzzer HA1 obtains electric, and alarm lamp HA1 obtains electric, sends out sound-light alarm.When superpressure 20%,
Intermediate relay KA2 coils obtain electric, and normally opened contact is closed, and quick pressure releasing valve group connects with pressure release valve group at a slow speed, and equipment is with most
Fast speed pressure release.Its normally-closed contact is opened simultaneously, and hydraulic pump motor dead electricity is stopped.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferable embodiment, embodiment of the present invention are not limited by the above embodiments, it should be appreciated that people in the art
Member can be designed that a lot of other modification and implementations, these modifications and implementations will be fallen in principle disclosed in the present application
Within scope and spirit.
