A kind of shutoff door ratchet check system, including shut-off door frame, shutoff door door leaf on shut-off door frame, hanging plate on shut-off door frame, rotating shaft on hanging plate, in rotating shaft and with handle support arm, the ratchet in rotating shaft, bearing pin on hanging plate, on bearing pin, the check pawl that can freely be rotated around bearing pin and be engaged with ratchet.Shutoff door ratchet check system of the present invention, structure reliability realizes check, holds shutoff door door leaf.In can be widely applied to boiler slag conveying system.
Description
Technical field
The present invention relates to a kind of shutoff door ratchet check system, in can be widely applied to boiler slag conveying system.
Background technology
Hydraulic shutoff door is lifted on boiler bottom slag underground, is furnace pressure when ensureing Maintenance of Boiler and operation and guarantee
The visual plant of maintenance personal's personal safety.But, due to being run under bad working environments for a long time, because of many originals such as malformation
Cause, equipment easily fails, and there is great hidden danger to maintenance personal's personal safety.
The content of the invention
Shutoff door ratchet that is reliable it is an object of the invention to provide a kind of structure, realizing check, hold shutoff door door leaf
Check system.
In order to achieve the above object, shutoff door ratchet check system of the present invention, including shut-off door frame, installed in shutoff door
Shutoff door door leaf on framework, the hanging plate on shut-off door frame, the rotating shaft on hanging plate, in rotating shaft simultaneously
Support arm with handle, the ratchet in rotating shaft, the bearing pin on hanging plate, on bearing pin, can be around bearing pin
The check pawl for freely rotating and being engaged with ratchet.
Shutoff door ratchet check system of the present invention, its operation principle is：When boiler slag conveying system is normally run, support arm is certainly
By sagging, shutoff door door leaf is also at plumbness.When boiler slag conveying system need to be repaired, support arm handle is pulled downward on, propped up
Check pawl snaps in ratchet after brace in place, realizes check, holds shutoff door door leaf, now horizontality at shutoff door door leaf.
After the completion of maintenance, check pawl is pulled up, check pawl abjection ratchet, support arm falls to free hang, shutoff door
Door leaf recovers to plumbness.
Shutoff door ratchet check system of the present invention, after check pawl pull-up, ratchet, support arm, support arm handle and rotating shaft
Synchronously can freely rotate.
Shutoff door ratchet check system of the present invention, using ratchet mechanism, when support arm handle is rotated clockwise, makes ratchet
Certain angle is turned over simultaneously, now, check pawl is slided on the back of tooth of ratchet, rear check pawl inserts the tooth of ratchet in place
Interior, check pawl prevents ratchet from rotating in an anti-clockwise direction, and realizes check.
In sum, shutoff door ratchet check system of the present invention, structure reliability realizes check, holds shutoff door door leaf.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Schematic structural view of the invention when Fig. 1 is boiler slag conveying system maintenance；
Fig. 2 is schematic structural view of the invention when boiler slag conveying system is normally run.
Specific embodiment
In Fig. 1, Fig. 2, shutoff door ratchet check system of the present invention, including shut-off door frame 1, installed in shut-off door frame
On shutoff door door leaf 2, installed in shut-off door frame on hanging plate 3, the rotating shaft 4 on hanging plate, in rotating shaft simultaneously
Support arm 5 with handle 9, the ratchet 6 in rotating shaft, the bearing pin 7 on hanging plate, on bearing pin, can be around
The check pawl 8 that bearing pin is freely rotated and engaged with ratchet.
Claims (1)
1. a kind of shutoff door ratchet check system, it is characterised in that including shut-off door frame, the pass on shut-off door frame
