Abstract
The invention relates to a heading machine cutting-head shaft water supply mechanism. The end of the cutting-head shaft (1) is axially connected with the water supply mechanism formed by a water supply pipe (3) and a seal connector (2); the water supply pipe (3) passes through the axes holes of reducer output (5), an input shaft (6) and a motor shaft (7) of a machine cutting head; the seal connector is formed by a shaft pipe (21) and a shaft sleeve (22) that rotate, slide, seal, match and connect mutually. The external diameter of the shaft pipe of the seal connector (2) thereof is relatively small, the rotating line speed is low, and the rotating match sealing is easy. The mechanism can greatly improve the leak tightness; in addition, the mechanism can be repaired and assembled or disassembled conveniently, thus saving time and labor.
Description
Technical field
What the present invention relates to is water supply mechanism for cutter head shaft of development machine, as the water supply mechanism of Vertical Axis Road-header cutter head shafts such as EBZ200, EBZ160, EBZ132.
Background technology
Cutting head of roadheader need supply water to the cut tooth by cutter head shaft when operation and cool off pick, and the dirt that disappears, fire extinguishing, prevents that methane gas from producing and blast, to guarantee production operation safety.
Cutting head of roadheader water supply at present is radially to supply water by be provided with the water supply axle sleeve on cutter head shaft, the water supply axle sleeve cooperates with cutter head shaft slip rotary seal at the cutter head shaft outer shroud, promptly at the water supply axle sleeve and cut and establish Glais ring (a kind of inlet seal circle) sealing between head axle fitting face.This structure since sliding sealing surface outside cutting head axle on the diametric plane, its relative linear velocity is higher, and this one also enters dust easily, so sealing life is shorter, influence the functional performance of machine, need change the once sealing circle general every month, is to carry out in underground passage owing to more change jobs, loading and unloading are inconvenient, and each repair and replacement all can cause the influence to producing.
Summary of the invention
The objective of the invention is to improve, a kind of sealing performance water supply mechanism for cutter head shaft of development machine preferably is provided,, reduce maintenance to prolong the sealing of water supply mechanism at above-mentioned the deficiencies in the prior art, and convenient for maintaining.
Technical scheme of the present invention is axially to be connected with the water supply mechanism that is made of the feed pipe and the head that is tightly connected at the cutterhead axle head, feed pipe passes reducer output, the power shaft of machine cutterhead, the axle center hole of motor shaft, be in the feed pipe setting reducer output shaft that is installed in the cutterhead of hollow, power shaft, the motor shaft, be provided with bearing arrangement and gasket set between feed pipe and reducer output shaft, power shaft, motor shaft endoporus; The head that is tightly connected rotates slipper seal mutually by central siphon and axle sleeve and is connected and constitutes; The head that is tightly connected places the outer end of feed pipe, and the inner of feed pipe is connected with cutterhead axle head threaded engagement, and the central siphon of the head that is tightly connected is connected with the outer end threaded engagement of feed pipe, and the axle sleeve of the head that is tightly connected is connected with external feed pipe threaded engagement; Or a inner that places feed pipe that is tightly connected, the central siphon of the head that is tightly connected is connected with cutterhead axle head threaded engagement, and the axle sleeve of the head that is tightly connected is connected with the inner threaded engagement of feed pipe.
The present invention adopts axial type water-supply structure mode, be that water inlet pipe is incorporated into the cutterhead axle head by electrical axis hole, reducer input shaft, output axle center hole, be connected and sealed by the head that is tightly connected, the central siphon external diameter of the head that is tightly connected (cutting the external diameter of head axle relatively) is very little, and rotational line speed reduces greatly, sealing easily is rotatably assorted, can improve sealing greatly, and easy to maintenance to being tightly connected, can carry out the maintenance of replacing formula, easy to loading and unloading, time saving and energy saving.
