Abstract
A hydraulic oil cooling device of a boom-type road-header comprises an oil collection block and a water cooling device, wherein an outlet of the oil collection block is connected with an inlet of the water cooling device by a tube, characterize din that a non-return valve is set on the tube between the outlet of the oil collection block and the inlet of the water cooling device and another tube is set between the outlet of the oil collection block and the inlet of the water cooling device and a wind cooling device is set on the tube. When the road-header is in normal work, one path of the high-temperature hydraulic oil is cooled by water and another path of the high-temperature hydraulic oil is cooled by wind and water and the oil is cooled by the two paths, thereby effectively reducing the oil temperature; when the road-header stops cutting, the hydraulic oil is cooled only by wind using a wind cooling device and precious water resource is saved.
Description
Technical field:
The utility model relates to a kind of cooling unit, particularly a kind of cooling unit of hydraulic system hydraulic oil of boom-type roadheader.
Technical background:
The mine is subjected to the tunnel condition restriction with boom-type roadheader at present, complete machine must be compact on structure design, the fuel tank size of its hydraulic system is little, and the hydraulic oil in the hydraulic system must cool off it through the cooling unit of peripheral hardware for this reason, could guarantee that its temperature can be not too high.The cooling unit of now domestic used boom-type roadheader all adopts water-cooling pattern, described cooling unit comprises oil-collecting piece and water cooler, water cooler is for being communicated with the heat abstractor of high temperature hydraulic oil, heat abstractor can be one and advance one and go out, radiator by metal tube dish one-tenth, also can be provided with import and outlet, hollow, tabular fin, the outlet of oil-collecting piece is connected by pipeline with the import of heat abstractor, after high temperature hydraulic oil flows into heat abstractor by the oil-collecting piece, outlet and pipeline through heat abstractor flow into fuel tank, the heat abstractor appearance is ceaselessly sprayed it by cooling water, and high temperature hydraulic oil is lowered the temperature rapidly.Because the down-hole is subjected to the restriction of various conditions, even the tunnel is moisture when big, also often be difficult to guarantee enough cooling waters, this is difficult to guarantee to drop to suitable temperature with regard to the temperature that makes hydraulic oil, the cooling effect that just present cooling unit can't satisfaction guaranted; Simultaneously, when the development machine head stops to cut, generally do not need to supply water, and cooling unit does not stop to supply water, and has wasted precious water resource.
Summary of the invention:
The purpose of this utility model provides a kind of hydraulic oil cooling device of the boom-type roadheader of saving water resource and can effectively lowering the temperature.
The realization the technical solution of the utility model is, a kind of hydraulic oil cooling device of boom-type roadheader, comprise oil-collecting piece and water cooler, the outlet of oil-collecting piece is connected by pipeline with the import of water cooler, it is characterized in that the pipeline between the outlet of described oil-collecting piece and the import of water cooler is provided with one way valve; Between the outlet of described oil-collecting piece and the import of water cooler, also and be connected to another pipeline, pipeline is provided with air cooling equipment.
The utility model has the advantages that during the development machine operate as normal, the return pressure of hydraulic system increases, one way valve is opened automatically, and high temperature hydraulic oil one tunnel is through water-cooled, and another road is through air-cooled, water-cooled, two the tunnel advance side by side cools off, thereby can reduce the oil temperature effectively, guarantees the machine operate as normal; When development machine stops cutting and sweeps at the end, during shipping work, the return pressure of hydraulic system reduces, and one way valve is closed automatically, stops simultaneously supplying water, and hydraulic oil is only undertaken air-cooled by forced air cooler, flow through water cooler again to enter fuel tank, has saved precious water resource.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 oil-collecting piece, 2 one way valves, 3 air cooling equipments, 4 fans, 5 forced air coolers, 6 water intaking valves, 7 water coolers.
The specific embodiment:
Referring to Fig. 1, the pipeline between the import of the outlet of described oil-collecting piece 1 and water cooler 7 is provided with one way valve 2, the outlet of described one way valve 2 one end connected set oil clots 1, and the other end is communicated with the import of water cooler 7; Described air cooling equipment 3 comprises forced air cooler 5 and fan 4, forced air cooler 5 can be to be provided with the radiator that the metal tube dish of import and outlet becomes, also can be provided with import and outlet, hollow, tabular fin, the outlet of the import connected set oil clot 1 of described forced air cooler 5, its outlet is communicated with the import of water cooler 7; Water intaking valve 6 interlocks of the water inlet pipe of described one way valve 2 and shower water cooler 7 when one way valve 2 is opened, are opened during water intaking valve 6, and when one way valve 2 was closed, water intaking valve 6 was closed simultaneously.
