Description
Technical field
Overhead door driving mechanism, relates to a kind of sterilizer part field of medical instruments field.
Background technology
Overhead door sterilizer is that hermatic door adopts lifting to carry out the sterilizer of opening and closing.The driving mechanism of the overhead door sterilizer under prior art is all that the type of drive adopting motor to add chain carries out driving, type of drive is not fast stablized, easily there is the phenomenon of chain breakage, thus cause door-plate to decline, and when running, there is larger noise; Further, the hermatic door under prior art after shutdown, mostly needs manually to lock, and practicality and the security performance of equipment are poor.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, and provide a kind of safe and reliable, noiselessness, prevents chain breakage situation, can the overhead door driving mechanism of automatic locking.
The utility model solves the technical scheme that its technical problem adopts: this overhead door driving mechanism, comprise the hermatic door be arranged on sterilizer, cylinder driver is installed in described hermatic door centre position, and hermatic door both sides installation and guide device, installs cylinder locking device inside hermatic door.Cylinder driver and cylinder locking device all realize automatically controlling by control system, utilize cylinder driver to realize the opening and closing of hermatic door, noiselessness, prevent chain breakage, cylinder locking device can automatic locking hermatic door, without the need to manual operation.
Described cylinder locking device comprises door locking cylinder and door insurance support bar, turning cylinder movable supporting is passed through bottom sterilizer in door insurance support bar lower end, door insurance support bar top is free end, the cylinder rod connection door insurance support bar medium position of door locking cylinder, the cylinder rod of door locking cylinder drives the door insurance support bar moving axis that rotates to rotate.When hermatic door decline is opened, door insurance support bar is arranged on inside hermatic door, and when hermatic door rises closed, door insurance support bar rotates around lower rotational axle under the cylinder rod telescopic action of door locking cylinder, be supported on hermatic door bottom, automatic locking is realized to hermatic door.
When the cylinder rod of door locking cylinder stretches out, the free end that door can be driven to insure support bar laterally rotates, and makes its support bar in hermatic door bottom, realize locking, before hermatic door declines, the cylinder rod of door locking cylinder shrinks, drive the free end of door insurance support bar to turn to the inside, realize unlocking.
Cylinder driver comprises driving cylinder and drives cylinder rod, drives cylinder to be vertically arranged on hermatic door centre position, driving cylinder rod to drive cylinder to be vertically arranged on hermatic door centre position from driving in cylinder to stretch out, driving cylinder rod to stretch out in driving cylinder.Drive cylinder and hermatic door to link together, by driving the bottom air inlet of cylinder to pass into Compressed Gas, cylinder head is obtaining pressure, drives cylinder rod to move down, and driving cylinder to drive door relative to moving up, realizing closing the door action.
Described guiding device comprises a gib block, gib block fixed head and directive wheel, door gib block totally two, be fixed on sterilizer doorframe both sides respectively by gib block fixed head, multiple directive wheel symmetry is arranged on the hermatic door left and right sides, and it is secondary that directive wheel and door gib block form slide rail.
Obstacle switch cover is installed at described sterilizer top.In door closing procedure, time hermatic door moves up, if be applied on obstacle switch cover effectively, can cause driving the means of deflation of cylinder interior to be fallen by earth pressure release, hermatic door stops rising or declining, and protects the maloperation of operator with this.
Compared with prior art, the beneficial effect that the technique scheme of this overhead door driving mechanism has is:
1, utilize cylinder driver to realize the opening and closing of hermatic door, can prevent chain breakage, cylinder locking device can automatic locking hermatic door, and without the need to manual operation, safe and reliable, practicality is high.
2, cylinder driver and cylinder locking device all adopt cylinder to control, and not only noise is low, and operates steadily, and reliability is high.
3, the slide rail pair that the guiding device of hermatic door adopts directive wheel and door gib block to be formed leads, and when hermatic door rising, decline, directive wheel slides up and down along gib block, the little and noiselessness of frictional force.
4, obstacle switch cover is installed at sterilizer top, can prevent maloperation, safer.In door closing procedure, time hermatic door moves up, if be applied on obstacle switch cover effectively, can cause driving the means of deflation of cylinder interior to be fallen by earth pressure release, hermatic door stops rising or declining, and protects the maloperation of operator with this.
Accompanying drawing explanation
Fig. 1 is this overhead door driving mechanism structure front view.
Fig. 2 is this overhead door driving mechanism structure left view.
Wherein: 1, drive the insurance of cylinder 2, hermatic door 3, door gib block 4, gib block fixed head 5, directive wheel 6, door locking cylinder 7, door support bar 8, obstacle switch cover.
Detailed description of the invention
Fig. 1 ~ 2 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 2 pair of the utility model.
With reference to accompanying drawing 1,2: overhead door driving mechanism, comprises the hermatic door 2 be arranged on sterilizer, cylinder driver is installed in hermatic door 2 centre position, and hermatic door 2 both sides installation and guide device, installs cylinder locking device inside hermatic door 2.Obstacle switch cover 8 is installed at sterilizer top.
Concrete, cylinder locking device comprises door locking cylinder 6 and door insurance support bar 7, and the cylinder rod of door locking cylinder 6 drives door insurance support bar 7 moving axis that rotates to rotate.Door insurance support bar 7 lower end is by turning cylinder movable supporting bottom sterilizer, and door insurance support bar 7 top is free end, cylinder rod connection door insurance support bar 7 medium position of door locking cylinder 6.
Cylinder driver comprises driving cylinder 1 and drives cylinder rod, drives cylinder 1 and hermatic door 2 to link together.
Guiding device comprises a gib block 3, gib block fixed head 4 and directive wheel 5, door gib block 3 totally two, be fixed on sterilizer doorframe both sides respectively by gib block fixed head 4, multiple directive wheel 5 symmetry is arranged on hermatic door 2 left and right sides, and directive wheel 5 and door gib block 3 form slide rail pair.
Switch two strokes of the driving cylinder 1 of this overhead door driving mechanism can realize carrying out descending operation to the hermatic door 2 of 450L ~ 810L overhead door sterilizer.The miscellaneous function of door locking device and obstacle switch cover 8 ensures the safety and reliability run.
The course of work is as follows: by driving the bottom air inlet of cylinder 1 to pass into Compressed Gas, driving cylinder 1 top to obtain pressure, driving cylinder rod to move down, driving the cylinder block of cylinder 1 relative to moving up, realizing closing the door action.After door off-position detects that hermatic door is closed, door locking cylinder 6 starts action, and driving gate insurance support bar 7 rotates to hermatic door 2 lower position, by door locking.During enabling, door unlock cylinder 6 is exitted, and door insurance support bar bar 7 rotates to right side, and hermatic door 2 unlocks.Drive cylinder 1 to start venting, due to Action of Gravity Field, the directive wheel 5 of hermatic door 2 moves down along door gib block 3, realizes door opening action.
