Abstract
The invention discloses an arc-shaped wear-resisting three-head helical body. The arc-shaped wear-resisting three-head helical body comprises a helical spindle, A-type helical blades, B-type helical blades, C-type helical blades, wear-resisting surfacing layers and arc-shaped stripes. The helical spindle is connected with the A-type helical blades, the B-type helical blades and the C-type helical blades, the blades are fixed onto the helical spindle in a completely welding mode in opposite left-handed and right-handed directions by taking the radial center as the basic point, and the helical blades at the radial base point are in butt joint into a tip shape and compose a helical set; the wear-resisting layers are surfaced on the outer edges of the helical blades with a radial inward range of 180 mm, and the arc-shaped stripes containing rigid points are surfaced on the surfacing layers, and equidistant three-head structures are formed at equal intervals on the surfacing layers. The arc-shaped wear-resisting three-head helical body has the advantages of being simple in structure, wear-resisting, durable, low in price, rapid in unloading, practical, safe, reliable and the like.
Description
Technical field
The present invention relates to wear-resisting three conveyor screws of arc, be particularly useful for the spirochetal helicallobe of the spiral car unloader of thermal powerplant fuel system.
Background technology
Thermal powerplant fuel delivery system contains the raw coal of outside supply, is mechanically unloaded to storage location aboard by transportation device, is carrying out next step concentrated conveying.Mechanical type in this process the used equipment of unloading coal is multiple, comprises spiral car unloader, pick formula car unloader, chain bucket unloader, tipper etc., and spiral car unloader is normally used equipment.
This equipment belongs to a kind of mechanization efficiently equipment of unloading coal, and raw coal can be unloaded rapidly from railway truck.Groundwork principle is that helicallobe is released materials in carriage rapidly to both sides by spirochetal rotation, reaches raw coal by compartment removal.The process of unloading coal is mainly by the rotation of the helicallobe on conveyor screw, coal to be screwed out coal to be unloaded along the direction of flight.Because field working conditions often exists helicallobe serious wear, particularly the helicallobe driving surface at two ends is not durable, its principal element is because helicallobe two ends are groundwork district face, what material was not wear-resisting and thin grade helicallobe causes, this cannot normally move with regard to causing because the damage of helicallobe causes equipment, and then affects coal storage for coal.
Summary of the invention
The present invention has developed wear-resisting three conveyor screws of a kind of novel arc, its objective is and provides a kind of simple in structure, and wear-resisting lasting, price is suitable, and discharging is quick, practicality, wear-resisting three conveyor screws of safe and reliable arc.
For achieving the above object, apparatus of the present invention are achieved through the following technical solutions, wear-resisting three conveyor screws of arc, comprise screw spindle, A type helicallobe, Type B helicallobe, C type helicallobe, wearable overlay, arc decorative pattern, screw spindle is connected with A type helicallobe, screw spindle is connected with Type B helicallobe, screw spindle is connected with C type helicallobe, A type helicallobe taking radial center as basic point to the left and right both direction fix with contrary rotation direction welding manner with complete penetraction and fusion in welding on screw spindle, form sharp mouth shape in the docking of the A of basic point place type helicallobe radially, be combined as A type spiral group, build-up wear-resistant layer within the scope of the radially inside 180mm of A type helicallobe outward flange, built-up welding order and thickness, after blade thrust driving surface preheating (50 ~ 100 DEG C), first use 1 ~ 2 layer of J506 welding rod built-up welding, form mortise face, ensure not coming off of wearing layer, then built-up welding number layer D-667 equably, reach thickness 6 ~ 8mm, after D-667 layer heap is soldered, built-up welding one deck D-65 again, built-up welding thickness is 2 ~ 3mm, D-65 layer heap postwelding, use again the uniform arc decorative pattern of D-65 built-up welding one deck rule, in the middle of arc decorative pattern, stiffened particle forms new blade thrust driving surface, the length of side of arc decorative pattern is 150-160mm, weld width is 20mm, thickness is 4mm, the thickness of wearable overlay and arc decorative pattern is wanted uniformity, Type B helicallobe is fixed and build-up wear-resistant layer and arc decorative pattern with A type helicallobe is the same with C type helicallobe, be combined as and contain the Type B spiral group of arc wearing layer and the C type spiral group containing arc wearing layer, and form evenly equidistant three header structures with determining deviation, on screw spindle, arrange successively taking radial center as basic point containing arc wearing layer A type spiral group, containing arc wearing layer Type B spiral group and containing arc wearing layer C type spiral group.
The invention has the beneficial effects as follows continuous equidistant three sharp mouth shape structures of utilizing that the docking of basic point place helicallobe radially forms and the wearing layer of end, it is feeding effectively fast, reach eat on a small quantity into, quick discharging, long-term use, reduce costs, with the arc wearable flower pattern band of hard point, reduce the relative sliding of material in the process of extruding work blade face with decorative pattern in conjunction with hard point, simple textural association and actv. technological measure, solve because the short helicallobe causing of life-span easy to wear is scrapped fault, improved the service efficiency of equipment.
