Abstract
The utility model provides an entry driving machine is cleaning device for hydraulic system comprises fixed plate, plug, packing ring, magnet ring and bolt, the one end of plug links together through screw thread and fixed plate, and the other end passes through the screw thread and is in the same place with bolted connection, magnet ring cover just separates through the packing ring between two adjacent magnet ring on the plug, have four connecting holes on the fixed plate, cleaning device passes through these four bolt fastenings for the connecting hole in hydraulic tank. The utility model discloses in the mainly used entry driving machine hydraulic tank, through the magnet set on the cleaning device in with hydraulic tank the iron fillings impurity adsorption in the hydraulic oil make the iron fillings impurity can not be at whole hydraulic system inner loop on the magnet set surface to play clean hydraulic system, protect the purpose of hydraulic pressure components and parts.
Description
Technical field
This utility model relates to a kind of cleaning device, especially a kind of tunneling machine hydraulic system cleaning device.
Background technology
Tunneling machine hydraulic system can produce a lot of tiny iron filings in running, and these iron filings can flow along with circulating of hydraulic oil, thus each hydraulic component is caused damage, especially for the rubber parts in hydraulic system.These tiny iron filings of present stage clean filtering are mainly filtered with oil absorption filter by the return filter installed in hydraulic system, both filters are disposable filter, after filtering a period of time, are necessary for being replaced, not reproducible use, relatively costly.
Utility model content
Technical problem to be solved in the utility model is: the return filter used during the cleaning of iron filings medium and small for tunneling machine hydraulic system at present and oil absorption filter, is disposable filter, and replacement frequency is fast, and use cost is high.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: providing a kind of tunneling machine hydraulic system cleaning device, structure includes: fixed plate, plug, packing ring, magnet ring and bolt；One end of described plug is linked together with fixed plate by screw thread, and the other end passes through screw thread and is bolted together；Described magnet ring is enclosed within plug, and is separated by packing ring between adjacent two magnet rings；Having four connecting holes in described fixed plate, cleaning device is fixed by bolts in hydraulic oil container by these four connecting holes.
During use, the tiny iron adsorption in hydraulic oil on magnet ring group surface, is made iron filings cannot flow in hydraulic system, thus plays the effect of cleaning solution force feed by the magnet ring group on described cleaning device；After cleaning device works a period of time, after it being taken out in hydraulic oil container, after being carried out, repeat use.
The invention has the beneficial effects as follows: by magnet ring in cleaning device, the tiny iron adsorption in hydraulic oil can be fixed by the absorption affinity of iron filings, reach cleaning solution force feed, reduce oil return, the replacement frequency of oil absorption filter, improve the service life of two kinds of filters, this cleaning device can be reused simultaneously, install, easy to clean, cost is relatively low.

Five, detailed description of the invention
Below in conjunction with the accompanying drawings the technology used in the present invention method is described further.
As it is shown in figure 1, in existing tunneling machine hydraulic system, be mounted with return filter 1 and oil absorption filter 3 on hydraulic oil container 2, and return filter 1 is installed on the top of hydraulic oil container 2, and oil absorption filter is installed on bottom hydraulic oil container 2；In development machine hydraulic oil system, hydraulic oil flows in hydraulic oil container 2 by return filter 1, and hydraulic oil pump, is input to hydraulic oil sucking-off in hydraulic oil container 2 in hydraulic system by oil absorption filter 3.In whole cyclic process, a tiny iron filings part is filtered on INVENTIONPaper filter core by return filter 1, oil absorption filter 3, and a part can be perforated through filter element and enter in other hydraulic component, and hydraulic pressure vigour part is caused damage.
The cleaning device 4 of tunneling machine hydraulic system provided by the utility model, structure is as in figure 2 it is shown, its structure includes: fixed plate 5, plug 6, packing ring 7, magnet ring 8 and bolt 9；Wherein the structure of plug 6 is as shown in Figure 4, and plug 6 one end is linked together with fixed plate 5 by screw thread, and the other end is linked together with bolt 9 by screw thread；Magnet ring 8 is enclosed within plug 6, and is separated by packing ring 7 between adjacent two magnet rings 8；As it is shown in figure 5, there are four connecting holes in fixed plate 5, cleaning device 4 is fixed by bolts in hydraulic oil container by these four connecting holes.
As it is shown on figure 3, on the basis of the structure (as shown in Figure 1) of original development machine, be fixed in hydraulic oil container 2 by cleaning device 4, and it is close to return filter 1.When hydraulic oil flows in hydraulic oil container 2 by return filter 1, by time around cleaning device 4, tiny iron filings in hydraulic oil, under the effect of the magnet ring 6 on cleaning device 4, it is attracted to the surface of magnet ring 6, iron filings cannot be flowed in hydraulic oil container 2 again, thus prevented these iron filings and circulated in whole hydraulic system, it is to avoid its damage to other hydraulic component.After using a period of time, cleaning device 4 can be taken out from hydraulic oil container, after it is carried out, be re-installed in hydraulic oil container, it is achieved reuse.
