Description
Technical field
The utility model belongs to the safety guard of coal-winning machine, particularly a kind of high inclination-angle coal-winning machine shoe.
Background technology
Spend greater than 10 when coal-winning machine work plane inclination angle, in case mechanical traction portion is malfunctioning, coal-winning machine might glide, and security incident takes place.Devices such as now existing band brake type shoe, disc type brake shoe and anti-skidding winch, the not enough problem of friction-tight power might appear digging in band brake type and disc type brake when high inclination-angle is mined, can not be effectively anti-skidding; Anti-skidding winch exists winch traction and shearer hauled-part traction to be difficult to stationary problem at present, influences its normal use.
Summary of the invention
The technical scheme that the utility model technical solution problem adopts is: a kind of coal-winning machine shoe of being made up of coal-winning machine frame and riser, be characterized on the coal-winning machine frame, fixing a bearing support and spline fitting, fix a bearing shell in the bearing support, be connected with spline external key draw key in the spline fitting, ratchet shaft is contained in the bearing shell slidably, and with snap ring location, the ratchet shaft right-hand member is provided with spline, flexibly connects with the internal key of interior external splines; The ratchet shaft left end is contained in the gear ratchet versatilely, and the indentation of establishing in a plurality of slotting pawls and the gear ratchet is housed versatilely contacts, and slotting pawl is equipped with slotting latch spring, and the ratchet gland is threaded with the gear ratchet; Interior external splines right-hand member is with junction plate of bolt, and the piston rod in junction plate and the oil cylinder is hinged, and the piston rod right-hand member is fixed a piston, adorns a spring between at the bottom of piston and the oil cylinder, adorns a two-position three way control valve between the oil inlet and outlet of the oil cylinder left and right sides.
The beneficial effects of the utility model are: this shoe is simple in structure, and reliable operation does not need the external world that the energy is provided in the course of the work, and is easy to maintenance.

The specific embodiment
With reference to accompanying drawing, a kind of coal-winning machine shoe, form by coal-winning machine frame 13 and riser 14, be characterized on coal-winning machine frame 13, fixing a bearing support 3 and spline fitting 7, fix a bearing shell 4 in the bearing support 3, in the spline fitting 7 with the external key of interior external splines 6 versatilely key be connected, ratchet shaft 2 is contained in the bearing shell 4 slidably, and with snap ring 5 location, ratchet shaft 2 left ends are contained in the gear ratchet 1 versatilely, and the indentation of establishing in three slotting pawls 18 and the gear ratchet 1 is housed versatilely contacts, to insert pawl 18 and be equipped with and insert latch spring 19, ratchet gland 17 is threaded with gear ratchet 1; Interior external splines 6 right-hand members are fixed a junction plate 8 with bolt 9, junction plate 8 is hinged with piston rod 11, piston rod 11 is fixedlyed connected with piston 12, and piston 12 and oil cylinder are adorned a spring 15 at 16 the end, adorns a two-position three way control valve 10 between oil cylinder 16 left and right sides oil inlet and outlets.Oil cylinder 16 is fixed on the riser 14, and riser 14 is fixed on the coal-winning machine frame 1.This device can be fixed in the coal-winning machine central fuselage, also can be fixed in the coal-winning machine two ends, and this moment, the outside should add dust cover.
Its course of work is: when up coal mining of coal-winning machine or traction, two-position three way control valve 10 places the next, and the chamber, front and back of oil cylinder 16 is communicated with oil return pipe 20, and piston 12 is in quick condition.Under the effect of oil cylinder 16 inner springs 15, piston rod 11 stretches out, and piston rod 11 drives junction plates, interior external splines 6 is moved to the left, external splines 6 and the engagement of ratchet shaft 2 external splines in making, and this moment, ratchet shaft 2 was fixed by spline with coal-winning machine frame 7, bore moment of torsion.Tooth in the gear ratchet 1 and the engagement of the pin row in the chute, ratchet mechanism guarantees that coal-winning machine can only upwards move, and can not move downwards.When haulage gear breaks down, by the engagement of the pin row in ratchet mechanism driven gear ratchet 1 and the chute, stop coal-winning machine to glide, play anti-skidding purpose.When the descending coal mining of coal-winning machine, operating mechanism can prop up rib, the coal-winning machine possibility that do not glide.At this moment, two-position three way control valve 10 places upper.Make the rod end chamber of oil cylinder feed hydraulic oil, piston rod 11 drives splines 6 and moves right, and spline 6 is thrown off with ratchet shaft 2 external splines, and at this moment, gear ratchet 1 can two-way any rotation, does not produce brake force, guarantees the descending smooth coal mining of coal-winning machine.
