Description
Technical Field
The utility model relates to a colliery is combined in pit and is adopted working face exploitation transport technical field, specific kinds of automatic flushing formula tail hydro-cylinder guard shields that says so, this utility model both can regard as the hydro-cylinder guard shield of scraper conveyor tail transmission portion, also can be used to wash the accumulational coal slime of tail transmission portion hydro-cylinder department.
Background
In order to prevent scattered coal blocks or coal slime from being accumulated and solidified to influence the expansion and contraction of the oil cylinder, most manufacturers currently adopt a mode of overlapping a protective cover at the oil cylinder of the tail transmission part of the scraper conveyor to realize the normal work of the oil cylinder, common engine tail oil cylinder protective covers are divided into two parts, namely an engine tail fixed protective cover and an engine tail movable protective cover, the top surfaces of the two parts of protective covers adopt an overlapping mode, the two protective covers respectively fix connecting components at two ends of the engine tail oil cylinder, and the engine tail movable protective cover can expand and contract along with the pushing section of the oil cylinder.
Disclosure of Invention
An object of the utility model is to provide an kind of automatic flush type tail hydro-cylinder guard shields for solve the coal slime that current tail hydro-cylinder guard shield exists and pile up the problem.
The purpose of the utility model is realized through the following technical scheme:
the automatic flushing type machine tail oil cylinder protective cover comprises a machine tail fixing protective cover, a machine tail movable protective cover and an automatic flushing device, wherein the machine tail fixing protective cover and the top surface of the machine tail movable protective cover are overlapped, the machine tail movable protective cover is overlapped on the machine tail fixing protective cover, the automatic flushing device and a connecting assembly at the end of an oil cylinder piston rod are welded on the inner wall of the machine tail movable protective cover, and an electromagnetic valve, an emulsion pipe and a related automatic control system are connected to the automatic flushing device.
, in the automatic flushing type machine tail oil cylinder protective cover, the machine tail movable protective cover is overlapped on the machine tail fixed protective cover to primarily block the scattered large coal blocks, and prevent the coal blocks from being accumulated at the piston rod of the oil cylinder to influence the telescopic pushing action of the oil cylinder.
, in the shield of the automatic flushing type tail oil cylinder, the automatic flushing device is formed by welding a semi-cylindrical shell and a semi-circular baffle, wherein the shell is internally provided with a cavity for temporarily storing the supplied emulsion so as to ensure that the emulsion is uniformly sprayed in a directional way, the baffle of the device is provided with three threaded liquid inlet holes for installing an electromagnetic valve and an emulsion pipe to supply the emulsion, the inner wall of the semi-cylindrical shell of the device is provided with a plurality of rows of liquid outlet holes for spraying the emulsion to flush the coal slime accumulated on a piston rod of the oil cylinder, the non-baffle side of the shell is also provided with three liquid outlet holes for flushing the coal slime accumulated at a return stroke when the piston rod of the oil cylinder contracts, the liquid outlet holes are threaded holes and can be used for installing related valve components so that the emulsion in the cavity is sprayed out when the pressure reaches degree, and the edge of the baffle of the automatic flushing device is additionally provided with four fixed threaded holes for fixing the automatic flushing device on a rib.
The beneficial effects of the utility model are mainly expressed in that the automatic flushing type tail oil cylinder protective cover, simple structure, high durability and convenient use, perfect functions, when the effect of the traditional tail oil cylinder protective cover is exerted, the automatic flushing device is added, the appearance of the shell body of the automatic flushing device plays a role in preventing scattered coal cinder from entering steps, the automatic flushing system with fixed time and orientation is additionally provided, and the accumulation and consolidation of fine coal slime are prevented, thus, the adverse effect caused by the expansion and translation movement of the oil cylinder due to the accumulation and consolidation of the coal slime is fundamentally eliminated, the problems of cleaning the fine coal slime and maintenance of the oil cylinder by using the traditional tail oil cylinder protective cover are also solved, a large amount of labor time is saved, and the working efficiency of the scraper conveyor is improved by entering steps.
