Fig. 3 is rearview of the present invention.
Symbol description among the figure:
1. motor; 2. reductor; 3. power transmission shaft; 4. sprocket wheel; 5. chain; 6. interior fire door; 7. outer fire door; 8. wedge; 9. spring attachment; 10. spring; 11. contact.
The specific embodiment
Describe with reference to the accompanying drawings the specific embodiment of the present invention in detail.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the present invention mainly is provided with motor 1, reductor 2, power transmission shaft 3, sprocket wheel 4, chain 5, interior fire door 6, outer fire door 7, wedge 8 and spring attachment 9.
Motor 1 links to each other with reductor 2, and reductor 2 links to each other with power transmission shaft 3.When motor 1 work, drive reductor 2 work, further so that power transmission shaft 3 rotations.Because it is too fast that the speed of opening and closing fire door does not need, so be provided with reductor 2 between motor 1 and power transmission shaft 3, realizes the opening and closing that fire door is stable with this.When the rotating speed of motor 1 is very little, also reductor 2 can be set.
Be fixed with two sprocket wheels 4 on the power transmission shaft 3, each sprocket wheel 4 all is arranged with a chain 5, and around sprocket wheel 4, then the opposite side from sprocket wheel 4 stretches out chain 5 from a gusset of sprocket wheel 4, and namely the both sides of sprocket wheel 4 are equipped with chain 5.The chain 5 of the same side on two sprocket wheels 4 is connected with interior fire door 6, and the chain 5 of opposite side is connected with outer fire door 7.Sprocket wheel 4 also can arrange more than two.
Plane relative with outer fire door 7 on the interior fire door 6 is provided with four wedges 8, and plane relative with interior fire door 6 on the outer fire door 7 is provided with four groups of spring attachments 9.Spring attachment 9 is provided with spring 10, is provided with contact 11 with the close end of wedge 8 on the spring 10.When fire door was closed, the contact 11 on the spring attachment 9 and wedge 8 close contacts on the interior fire door 6 so that the spring 10 of spring attachment 9 is compressed, thereby compressed interior fire door 6 and outer fire door 7.Spring attachment 9 also can be other form, only needs to guarantee that it can get final product the fire door compression.
Because interior fire door 6 contacts with the Cremation Machine burner hearth, so interior fire door 6 is preferably the high temperature aluminosilicate material.
The below is illustrated the course of work of the present invention:
When motor 1 work, drive reductor 2 and rotate, further drive power transmission shaft 3 rotations that are connected with reductor 2.Because sprocket wheel 4 is fixedly connected with power transmission shaft 3, so the rotation of power transmission shaft 3 can be with movable sprocket 4 to rotate together.Be set in respectively again the both sides of two sprocket wheels 4 because of two chains 5, the chain 5 of the same side on two sprocket wheels 4 is connected with interior fire door 6, the chain 5 of opposite side is connected with outer fire door 7, so so that two chains 5 be pressed on two sprocket wheels 4, so when two sprocket wheels 4 rotate, the upwards walking of outer fire door 7, interior fire door 6 is walked downwards, and spring attachment 9 beginnings on the outer fire door 7 contact with the wedge 8 on the interior fire door 6.Wedge 8 is provided with a slope, along with walking on of outer fire door 7 and interior fire door 6, the gradient of the wedge 8 of spring attachment 9 contacts is more and more higher, and spring attachment 9 little by little shortens, thereby interior fire door 6 and outer fire door 7 are compressed, make whole fire door be in closed condition.
When motor 1 counter-rotating, outer fire door 7 is walked downwards, the upwards walking of interior fire door 6, and the gradient of the wedge 8 of spring attachment 9 contacts is more and more lower, and compressed spring attachment 9 little by little extends, thereby makes whole fire door be in open mode.
The present invention can also be connected with handwheel at the other end of power transmission shaft 3, when the situation of outage occurring, just can drive power transmission shaft 3 rotations by rotating handwheel, thus the opening and closing of control fire door.
The above person of thought; only be specific embodiments of the invention, when not limiting scope of the invention process with this, therefore the displacement of its equivalent assemblies; or according to equivalent variations and modification that scope of patent protection of the present invention is done, all should still belong to the category that claims of the present invention are contained.
