Summary of the invention
The purpose of this utility model is to design a kind of new-type door opening and closing device that the fire door position memory is got off of having, be intended to reach accurate rapidly opened and closed fire door by this device, and then improve the working reliability of door opening and closing mechanism, and improve the service efficiency of equipment, prolong the work-ing life of fire door.
Technical solution of the present utility model is achieved in that
A kind of door opening and closing device with memory function comprises and gets a mechanism and electrical control system that a wherein said mechanism of getting is made up of inner frame and outside framework, pressure bolt oil cylinder is housed on the inner frame, presses down bolt oil cylinder and Ti Men oil cylinder; A web member is respectively arranged on the left and right side position of outside framework, the left side web member dump ram that is fixedly hinged, the front end and the frame of this oil cylinder are movably hinged; The right side web member then is connected with frame by hinge, allow outside framework to rotate around hinge, it is characterized in that described upper and lower pressure bolt oil cylinder, carry the MTS transmitter all is housed in an oil cylinder and the dump ram, these transmitters all with electrical control system in the PLC industrial computer keep being electrically connected; When fire door is operated, by last pressure bolt oil cylinder, the spring latch that presses down bolt oil cylinder pushing fire door carries out loose door operation, an oil cylinder and dump ram are finished the lifting fire door respectively and fire door centers on the action that hinge rotates to an angle by carrying then, the straight-line displacement of described each oil cylinder is all noted by electrical control system, and under the control of electrical control system, make all automatically flexible in regular turn corresponding distance of each oil cylinder, thereby the operation that fire door is accurately won in realization.
Described electrical control system comprises the PLC industrial computer, wherein contains PLC processing module and PLC execution module, and described PLC processing module receives 4～20mA standard signal that the MTS transmitter is carried, and can realize communicating by letter with the PC upper computer; Described PLC execution module is then controlled the rly. and/or the magnetic valve of hydraulic circuit according to the instruction of PC upper computer.
Compared with prior art, the utility model has the advantages that conspicuously, mainly comprise:
1, the oil cylinder that is disposed all has the MTS built-in sensors, and to the height of each fire door, positions such as angle of inclination make it to have memory function by electrical control.
The flexible automatically particular location that arrives of each oil cylinder when 2, fire door being operated, the switching fire door is very accurate, and fast, positional value need not frequent adjustment.Improved the service efficiency of equipment.
3, prolonged the work-ing life of fire door.
Description of drawings
The utility model drawings attached 5 width of cloth, wherein:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A view of Fig. 1;
Fig. 4 is the B-B view of Fig. 1;
Fig. 5 is a MTS oil cylinder control principle block diagram.
In the drawings:
1. inner frame, 2. outside framework is 3. carried an oil cylinder, and 4. pedestal fairload is pressed the bolt oil cylinder on 5., 6. presses down the bolt oil cylinder, 7. dump ram, 8. frame, 9. hinge.
Embodiment
As Fig. 1～a kind of door opening and closing device that has memory function shown in Figure 5, this device is made up of inner frame 1, outside framework 2, and inner frame is equipped with pedestal fairload 4 and can moves around in outside framework, and internal and external frame is by section steel manufacture.Outside framework is connected above the frame 8 by hinge 9, and under the promotion of dump ram 7, inner frame, outside framework can be rotated around hinge 9 when getting; Dump ram 7 built-in MTS transmitters can be noted the slant range of each fire door by electrical system, when fire door is operated, flexible automatically this distance of oil cylinder is got final product.When door opening and closing device and fire door during, carry out loose door operation by last pressure bolt oil cylinder 5, the spring latch that presses down bolt oil cylinder 6 pushing fire doors to good position; Last pressure bolt oil cylinder 5, press down the built-in MTS transmitter of the same configuration of bolt oil cylinder 6, equally the bolt position memory of each fire door is got off, each oil cylinder this distance of stretching automatically gets final product during operation.After bolt was pressed pine, inner frame 1 moved up under the promotion of carrying an oil cylinder 3, by the hook on the inner frame fire door is lifted from firedoor frame, had reached the function of opening fire door; Carry the built-in MTS transmitter of an oil cylinder 3 same configurations, the height location of each fire door can be memorized, flexible automatically this distance of oil cylinder gets final product during operation.Finished switching by this a series of action to fire door.The built-in MTS continuity sensor of each oil cylinder makes that to get the stroke that closes fire door very accurate, has reached the purpose of accurately winning fire door.
