Description
Technical field
The present invention relates to a kind of mine individual hydraulic prop, relate to or rather a kind of installing component of mine individual hydraulic prop.
Background technology
In the mine individual hydraulic prop that uses at present, the component locations that triple-use valve is installed is different, and the old t shore of DW is on column cap, DWX floating type pillar is handle valve body, the two telescopic type pillars of DWS in recent years, have again producer that parts are welded on the oil cylinder outer wall on cylinder sleeve.Although all played the effect of liquid filling pole-raising, overload overflow, unloading prop drawing, can only be disposable use, in case can not change after damaging.
And the parts that triple-use valve is installed are critical components of pillar, as long as the φ of these parts 42 holes generations are overproof, burn into damages, whole pillar can not use, and could use after must carrying out large repairs.At present, the method for each t shore overhaul is: the old t shore of DW is to slice off bad column cap, welds new column cap; DWX floating type pillar is scrapped the handgrip valve body, more renews part; The two telescopic type pillar cylinder sleeves of DWS are scrapped, and more renew part; The outside weld formula slices off failed part, fills the new part of weldering.Cause like this that overhaul cost is high, the cycle is long, manual machine has high input, and parts recycling rate is low, waste is large.
Summary of the invention
The object of the invention is to overcome the interchangeable triple-use valve cylinder base that the deficiencies in the prior art provide a kind of mine individual hydraulic prop, easy accessibility, quick, economical and practical.
The present invention includes oil cylinder, in the middle of oil cylinder, liquid-through hole is arranged, it is characterized in that: be close to the pedestal of oil cylinder outer wall welding hollow, place the cylinder base of hollow in pedestal, the cylinder base total length equates with pedestal; Be provided with the pedestal interstitial hole in the middle of described pedestal, communicate with liquid-through hole, right-hand member is established a pedestal link slot in the hole, and on cylindrical, corresponding pedestal link slot is opened an arc notch, is convenient to pound into connecting steel wire with being connected; Limit, described pedestal left end hole is opened a pedestal and is only revolved the hole; Be provided with the cylinder base interstitial hole in the middle of described cylinder base, communicate with pedestal interstitial hole, liquid-through hole, cut twice cylinder base seal groove on cylindrical, twice " O " RunddichtringO is installed; In described cylinder base right-hand member hole, corresponding pedestal link slot has the cylinder base link slot, and the installation of being connected with the cylinder base link slot of pedestal link slot connects steel wire; The corresponding pedestal in limit, described cylinder base left end hole only revolves the hole and has cylinder base and only revolve the hole, and pedestal only revolves hole, cylinder base and only revolves the installation latch hole in, is used as only to revolve.
Shape one end of described connection steel wire is with elbow, and is for convenience detach.
As shown from the above technical solution, the present invention is simple in structure, is convenient to processing, at cylinder base
φ 42 holesNeed not destroy any position during overhaul after overproof, burn into damages, only need to change the cylinder base of two kilograms of less thaies, pillar can use, and easy accessibility, maintenance cost are low, use safety; Saving steel is obvious, remarkable in economical benefits.Take DW25-250/100 pillar model as example, blank gross weight 4.85kg of the present invention, net weight 2.97kg, column cap, handle valve body, cylinder sleeve are used more than half of materials less.During overhaul, the column cap that the old t shore of DW is scrapped is that the handle valve body that 8.7kg, DWX floating type pillar are scrapped is that the cylinder sleeve that the two telescopic type pillars of 9.6kg, DWS are scrapped is 6.8kg, and the present invention only need change the cylinder base of a net weight 0.9kg, than the average saving steel 6.5kg of above three kinds of pillars.A general colliery be 5000 with the post amount, but 32.5 tons of saving steels.
