The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain, belong to the scope that the utility model is protected.
According to embodiment of the present utility model, provide a kind of Manual reciprocating fire grate.
as depicted in figs. 1 and 2, Manual reciprocating fire grate according to the utility model embodiment, comprise rocker 1, described rocker 1 is located at boiler 2 inboards, and, the outside that the front end of rocker 1 extends to boiler 2 is connected with crank 3, between the madial wall of described rocker 1 and boiler 2, by fore bearing 4, with rear bearing 5, be connected respectively, on the rocker 1 of boiler 2 inboards, be provided with 2/3 gear 6, the upside of 2/3 gear 6 is tilting translation dolly 7, the bottom, upper end of translation dolly 7 is provided with the horizontal rack 8 that is meshed with 2/3 gear 6, the bottom, lower end of translation dolly 7 is provided with flat wedge 9, on flat wedge 9 and boiler 2 base plates, by roller bracket 10 fixing support rollers 11, match, the top of translation dolly 7 is provided with walking beam 12, walking beam 12 is provided with some travelling oven beams 13, wherein, undermost travelling oven beam 13 laminates on the fixing point stove beam 14 of boiler 2, between adjacent two travelling oven beams 13, be connected with stationary furnace beam 15, intersecting setting between stationary furnace beam 15 and travelling oven beam 13, described stationary furnace beam 15 is fixed on boiler 2 madial walls by built-in beam 16.
It is 10 that the utility model adopts the number of teeth of 2/3 gear 6,2/3 gears 6, and the pressure angle of 2/3 gear 6 is 20 °, can save the raw material while producing by hot investment casting, one-shot forming, save processing cost, improved production efficiency, corresponding, the number of teeth of horizontal rack 8 is 9.
In the utility model, the number of described travelling oven beam 13 is N, and the number of stationary furnace beam 15 is N-1, wherein, and N >=2.Because travelling oven beam 13 and stationary furnace beam 15 are in overlapped mutual situation of pressing a part in design, like this, the stove beam has just formed the low gradient after front height on the whole.When the gradient was between 10 ° to 15 °, coal seam more was conducive to moving ahead of coal seam under the effect of sliding force.
