Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 4, a kind of fire door switching mechanism, the fire door 2 comprising body of heater 1 and be arranged in the middle part of body of heater, fire door abuts with door damper 3 and fire door gripper shoe 4, body of heater top is provided with two cylinders 5, the piston rod end of two cylinders is all set on joint pin 6, joint pin two ends are all connected with the active swing arm end of L-type swing arm 7, be connected with body of heater top by rotating shaft 8 in the middle part of L-type swing arm, the passive swing arm end of L-type swing arm is connected with telescopic lever 9 one end axle, the telescopic lever other end is connected with the top axle of fire door heat shield 10, fire door heat shield is connected with door damper axle, fire door heat shield cover is established and is fixed on fire door surface, and be provided with high temperature resistant heat insulation layer 11 between fire door heat shield and described fire door, the temperature of fire door is convenient to intercept, reduce heat to the damage of the parts that are in transmission connection, prevent distortion stuck, extension spring 12 is provided with between furnace body outer wall above fire door heat shield top and described fire door heat shield, telescopic lever is by upper connecting rod 901, bolt 901, butterfly nut 903 and lower link 904 connect to form, lower link one end is provided with protruding 905, described upper connecting rod one end is provided with the groove 906 be set in projection, bolt is through groove and protruding and be fixedly installed by butterfly nut.
Wherein, fire door heat shield surface is fixed with carrier bar 13, and carrier bar one end is connected with door damper axle, and the other end and telescopic lever axle connect, and facilitates the fixing of axle; The two ends of telescopic lever are all threaded with connector 14, and threaded connection place is provided with nut 15, can adapt to regulate length, and lock in place, loosen in can not re-using; Cylinder is connected with support 17 axle, and support is fixed on body of heater top, is provided with heat insulation foam 17 between support and body of heater top, the transmission of trap heat, reduces high heat and causes damage to cylinder.Fire door heat shield both side ends is provided with handle 18, and handle is arranged vertically downward, in emergency circumstances conveniently pulls handle, and can make to exert oneself, open fire door fast.
The operation principle of the present embodiment is as follows:
During use, the piston rod retraction of cylinder, joint pin is pulled to move, the L-type swing arm being arranged on joint pin two ends is made to do counterclockwise movement, owing to connecting with body of heater axle, described passive swing arm end end is done ascending motion and drives telescopic lever to do ascending motion, telescopic lever pulls fire door heat shield, fire door heat shield rotates around the axle be connected with door damper, realizes the unlatching of fire door, otherwise the piston rod of cylinder stretches out, clockwise movement is done in L-type swing arm, drive telescopic lever to do descending motion, fire door heat shield is resetted, realize fire door and close.
When cylinder is without air pressure or when revealing not enough, piston rod cannot give the pressure that fire door is closed downwards, at this moment, extension spring is pullled fire door heat shield and is enclosed the pivot done upwards, fire door is realized automatically to open, the abnormal work of staff's very first time discovering device can be made, early find, early keep in repair, early use; When fire door cannot pull open by the pulling force of extension spring, (rotating shaft place is due to high temperature deformation, produce larger frictional force), direct pull is shaken hands, and handle is fixedly connected with fire door heat shield, pulls handle namely to allow fire door heat shield do pivot, active force acts directly on fire door heat shield, reduce idle work, the parts that also prevent from being in transmission connection have stuck, cannot by force transmission to fire door, like this can by oven door opening, handled easily.
When cylinder is stuck or pressure is excessive cannot normally run time (piston rod stretches out and cannot bounce back), now fire door heat shield is continuously applied the power of closing fire door downwards, extension spring also cannot realize opening fire door, now only need to unload butterfly nut, bolt is extracted, the projection of lower link can do piston movement in the groove of upper connecting rod, wherein bolt wears in the middle part of cell wall that room is groove and protruding end, projection length is consistent with depth of groove, the intensity of junction can be ensured like this, also can ensure that projection can have enough motion surpluses in a groove; After unloading bolt, pull handle, oven door opening, the lug boss of lower link enters in groove, can not cause conflict, realizes the manually opened fire door under stuck state.
The utility model has perfect unlatching fire door measure, ensure can open fire door in any case, and cylinder damage degree reduces, rotating shaft is opened fire door and is also solved fire door because of high temperature deformation and cause stuck phenomenon, there is the characteristic automatically opening fire door, the normal operation of guarantee equipment and production, reduce the loss, and improves production capacity.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
