Description
Technical field
The utility model relates to a kind of mine individual hydraulic prop, relates to a kind of installing component of mine individual hydraulic prop or rather.
Background technology
In the mine individual hydraulic prop that uses, the component locations that triple-use valve is installed is different at present, and the old t shore of DW is on column cap, DWX floating type pillar is the handgrip valve body, the two telescopic type pillars of DWS in recent years, have producer that parts are welded on the oil cylinder outer wall again on cylinder sleeve.Though 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 generation of φ 42 holes of these parts is overproof, burn into damages, then 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 overhaul cost height, cycle long like this, manual machine has high input, and parts recycling rate is low, waste is big.
Summary of the invention
The purpose of this utility model 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 utility model comprises oil cylinder, in the middle of the oil cylinder liquid-through hole is arranged, and it is characterized in that: be close to the pedestal of oil cylinder outer wall welding hollow, place the cylinder base of hollow in the pedestal, the cylinder base total length equates with pedestal; Be provided with the pedestal interstitial hole in the middle of the described pedestal, communicate with liquid-through hole, establish a pedestal link slot in the right-hand member hole, corresponding pedestal link slot is opened an arc notch on the cylindrical, is convenient to pound into being connected steel wire with removing; 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 the described cylinder base, communicate with pedestal interstitial hole, liquid-through hole, cut twice cylinder base seal groove on the cylindrical, twice " O " RunddichtringO is installed; Corresponding pedestal link slot has the cylinder base link slot in the described cylinder base right-hand member hole, and the pedestal link slot is connected steel wire with interior installation of cylinder base link slot; 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, only revolves usefulness.
Shape one end of described connection steel wire has elbow, and is for convenience detach.
As shown from the above technical solution, the utility model is simple in structure, is convenient to processing, at cylinder base
φ 42 holesOverproof, burn into need not destroy any position when damaging the back overhaul, only needs to change the cylinder base of two kilograms of less thaies, and pillar can use, and easy accessibility, maintenance cost are low, use safety; The saving steel are obvious, remarkable in economical benefits.Be example with DW25-250/100 pillar model, the utility model blank gross weight 4.85kg, net weight 2.97kg, column cap, handgrip valve body, cylinder sleeve are used more than the half of materials less.During overhaul, the column cap that the old t shore of DW is scrapped is that the handgrip 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 utility model only need be changed the cylinder base of a net weight 0.9kg, on average saves steel 6.5kg than above three kinds of pillars.A general colliery be 5000 with the post amount, can save 32.5 tons of steel.
