Abstract
The utility model discloses a three-head wear-resistant screw device which comprises a screw main shaft, A type screw vanes, B type screw vanes, C type screw vanes and wear-resistant bead weld layers. The screw main shaft is connected with the A type screw vanes, the B type screw vanes and the C type screw vanes. The A type screw vanes take a radial center as a base point and are fixed on the screw main shaft in a full penetration weld mode with opposite screw directions in the left direction and the right direction. The A type screw vanes are in butt joint to form a tip mouth shape at the radial base point and an A type screw group is combined. The wear-resistant layers are in bead weld on the outer edges of the A type screw vanes inwards and radially within a range of 180mm. The B type screw vanes and the C type screw vanes are fixed in the same way with the A type screw vanes, the wear-resistant layers are welded in the same way with the A type screw vanes, and therefore a B type screw group with the wear-resistant layers and a C type screw group with the wear-resistant layers are formed and an even equidistance three-head structure is formed with fixed intervals. The three-head screw device has the advantages of being simple in structure, wear-resistant, fast in discharging, practical, safe, reliable and the like.
Description
Technical field
The utility model relates to three abrasion-resistance screw devices, is particularly useful for the spirochetal helicallobe of the spiral car unloader of thermal powerplant fuel system.
Background technology
The thermal powerplant fuel delivery system contains the raw coal with the outside supply, is mechanically unloaded to the storage location aboard by transportation device, is carrying out next step concentrated conveying.Mechanical type in this process equipment that uses 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 efficient mechanization equipment of unloading coal, and raw coal can be unloaded rapidly from railway truck.The groundwork principle is that helicallobe is released materials in carriage rapidly to both sides by spirochetal rotation, reaches raw coal by the compartment removal.The process of unloading coal is mainly by the rotation of the helicallobe on conveyor screw, the direction of coal along flight to be unloaded the coal back-out.Because often there is the helicallobe serious wear in field working conditions, 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 just causes the damage due to helicallobe to cause equipment normally to move, and then affects the standby coal of coal storage.
Summary of the invention
The utility model has been developed a kind of three novel abrasion-resistance screw devices, and its objective is provides a kind of simple in structure, and wear-resisting lasting, price is suitable, and discharging is quick, practicality, three safe and reliable abrasion-resistance screw devices.
for achieving the above object, the utility model device is achieved through the following technical solutions, three abrasion-resistance screw devices, comprise screw spindle, A type helicallobe, the Type B helicallobe, C type helicallobe, wearable overlay, screw spindle is connected with A type helicallobe, screw spindle is connected with the Type B helicallobe, screw spindle is connected with C type helicallobe, A type helicallobe take radial center as basic point to the left and right both direction fix with opposite rotation direction welding manner with complete penetraction and fusion in welding on screw spindle, form sharp mouth shape in the docking of the basic point A of place type helicallobe radially, be combined as A type spiral group, build-up wear-resistant layer in the radially inside 180mm scope of A type helicallobe outward flange, the Type B helicallobe is fixed and the build-up wear-resistant layer with A type helicallobe is the same with C type helicallobe, be combined as the Type B spiral group that contains wearing layer and the C type spiral group that contains wearing layer, and form evenly equidistant three header structures with determining deviation, arrange successively take radial center as basic point on screw spindle and contain wearing layer A type spiral group, contain wearing layer Type B spiral group and contain wearing layer C type spiral group.
The beneficial effects of the utility model are continuous equidistant three sharp mouth shape structures of utilizing that the place's helicallobe docking of basic point radially forms and the wearing layer of end, it is feeding effectively fast, reach eat on a small quantity into, quick discharging, the long-term use reduces costs, simple textural association and actv. technological measure, solution has improved the service efficiency of equipment because the short helicallobe that causes of life-span easy to wear is scrapped fault.
