Description
Technical field
The utility model relates to the internal spraying system in a kind of cutting head of roadheader.
Background technology
At present, the Internal Spraying System of Driving Machinrey characteristics are that the part that relates to is more, and the seal point of water route complex structure, necessary setting is many; Because the general movable sealing of adopting more; Exist between seal receptacle and the spacer to relatively rotate, each seal point all might become leakage point, and sealing reliability is low.This sealing is in case leak; Cooling water will get into the cutting arm inside cavity, and important spare parts such as the bearing of UNICOM, main shaft, axle sleeve will damage with it, and this fault takes place repeatedly in practical application; Cause equipment downtime; In order to reduce the shutdown influence that this fault causes equipment, most coal mine tunneling machines are gone into the well when installing, and supply water and promptly be removed or close in the outside of internal spraying system.
The utility model content
The purpose of the utility model is: to existing the leakage point of hidden danger many in the existing Internal Spraying System of Driving Machinrey, cause a series of problems such as maintenance is big, application life is short, the internal spraying system in a kind of new cutting head of roadheader is provided.
The purpose of the utility model is achieved in that the internal spraying system in a kind of cutting head of roadheader; Comprise the centre bore of water service pipe, cut main shaft and be distributed in the nozzle of cutterhead end; The inner nozzle water route of the centre bore of cut main shaft and cutterhead is linked up, and it is characterized in that:
A) cutting motor adopts hollow core shaft; Be provided with the through hole of concentric in the power shaft of reductor and the output shaft; Cutting motor, reductor and after the cut main shaft is connected successively, the centre bore of the hollow core shaft of cutting motor, the through hole in the reductor and cut main shaft is positioned on the same axis;
B) after the front end of built-in water service pipe passes the hollow core shaft and the through hole in the reductor of cutting motor successively; Be tightly connected with the centre bore of cut main shaft again and form built-in water route; The cutting motor outer end is provided with the water flowing flange, and the rear end of built-in water service pipe is docked with outside feed pipe through rotary sealing appts by the water flowing flange.
In the scheme of the utility model: the joint portion of the hollow core shaft of described cutting motor and reductor power shaft is with support sleeve; Described built-in water service pipe is connected the built-in water route of formation that is tightly connected through flange and O type circle with the cut spindle hole.The below of described water flowing flange is provided with the leak detection mouth.
In the scheme of the utility model: built-in water service pipe adopts static seal to be connected with the end of reductor output, and the centre bore of cut main shaft adopts static seal to dock with the inner nozzle water route of cutterhead.
In the scheme of the utility model: described built-in water service pipe is a metallic water pipe.Described metallic water pipe can be a stainless steel waterpipe, or copper plumbing.
The advantage of the utility model is: because cutting motor is adopted hollow core shaft; Be provided with the through hole of concentric in the power shaft of reductor and the output shaft; In the middle of them, place built-in water service pipe, the relative movement part that has significantly reduced each existence in cutting motor and the reductor influences inner water route; Because the end of built-in water service pipe and reductor output and the centre bore of cut main shaft is tightly connected, the centre bore of cut main shaft docks with the nozzle water route static seal of cutterhead inside; Make whole inner water route not have the connection of relative movement part, stop or significantly reduced the hidden danger of inner water route appearance leakage; Because the below of water flowing flange is provided with the leak detection mouth, in case rotary sealing appts damages, cooling water will can prevent effectively that cooling water from getting into motor or reductor cavity from detecting a mouthful outflow; Because water service pipe is longer, in cutting motor and reductor joint portion lining is set and play supporting role.The utility model compact conformation, easy to maintenance.
