Abstract
The invention provides a zipper type dust cover applied to a piston rod in a hydraulic loading system of a vertical mill, and solves the technical problem of overburdened replacement of the dust cover of the piston rod. The dust cover is characterized in that two chain belts in a zipper are respectively fixed on two long sides of a rectangular textile, after the zipper is closed, the rectangular textile forms a cylindrical shape, and the length of the cylindrical shape is greater than the maximum stroke of the piston rod. According to the dust cover, the thought of solving the problem of overburdened replacement of the dust cover of the piston rod is changed, a new way is developed, a new technical scheme is provided according to the thought of easiness in replacement, in comparison with the prior art, the cost is greatly reduced, and the replacement is simple and high in efficiency, thus the working performance of complete equipment of the vertical mill is remarkably improved.
Description
Technical field
The present invention relates to Vertical Mill hydraulic loading system, especially the dust-proof cover of the piston rod in Vertical Mill hydraulic loading system.
Background technique
In hydraulic loading system in Vertical Mill complete sets of equipment, the piston rod of oil cylinder is connected with earrings on grinding roller.The environment dust of this equipment availability is a lot of, for preventing that dust, foreign material from dropping on piston rod and then entering in oil cylinder, oil cylinder and piston rod are caused to damage, all cylinder piston rods all cover dust-proof cover, specifically the two ends of dust-proof cover are separately fixed on grinding roller on earrings and oil cylinder, and dust-proof cover does reciprocal stretching operation with piston rod.This back and forth moves, and not only intensity is high, and frequency is fast, and its life-span is significantly less than piston rod, and therefore it belongs to easily damaged parts, need to often change.While changing it, first earrings on grinding roller is unloaded from piston rod; The dust-proof cover of damage is exited from the outer end of piston rod, newer dust-proof cover is enclosed within on piston rod; Finally earrings on grinding roller is arranged on piston rod.Visible, on a cylinder piston rod, change that dust-proof cover need to first unload, earrings is respectively once on rear dress grinding roller.Because earrings weight on grinding roller is larger, load and unload on a grinding roller earrings very difficult, all need a large amount of manpowers or special tool at every turn; And it is very frequent to change dust-proof cover on each piston rod, on a Vertical Mill complete sets of equipment, just there are several oil cylinders, all these have increased the weight of operator's burden greatly, have also affected Vertical Mill complete sets of equipment working efficiency.Change if delayed, bring hidden danger can to the safe operation of equipment, possibility can cause larger loss.
In order to alleviate the burden of changing dust-proof cover, up to the present mostly those skilled in the art are from reduce the number of times of changing bellow type dust-proof cover within the unit time, start with from the working life that extends bellow type dust-proof cover, solve this problem, start with along the many materials from selection bellows of this thinking art technology people.But the scheme that this thinking produces faces a difficult selection, be directly proportional the working life of bellows to its price.
Summary of the invention
The calm easily changeable angle of the present invention proposes a kind of technological scheme of the zip mode dust-proof cover that is applied in piston rod in Vertical Mill hydraulic loading system, this scheme does not need to load and unload earrings on grinding roller in the time changing piston rod dust-proof cover, to solve the piston rod dust-proof cover problem that over-burden of changing.
The object of the present invention is achieved like this: it comprises earrings and oil cylinder on grinding roller, it is characterized in that: two chain bands in a secondary slide fastener are separately fixed on two long limits of rectangle or parallelogram fabric, the tubular dust-proof cover that after this slide fastener closes, this rectangle or parallelogram fabric become, the length of this tubular dust-proof cover is greater than the range of piston rod, and the two ends of tubular dust-proof cover are separately fixed on grinding roller on earrings and oil cylinder with fixture.Open slide fastener and the fixture of old tubular dust-proof cover, old tubular dust-proof cover is launched into rectangle or parallelogram, can directly on piston rod, remove old tubular dust-proof cover; Otherwise, new dust-proof cover can be directly installed on piston rod, in the time changing, do not need to load and unload earrings on grinding roller.
The present invention solves the thinking of changing dust-proof cover over-burden problem before changing invention, Ling Pixin road, calm easily changeable thinking is started with, new solution has been proposed, compared with prior art, cost of the present invention reduces greatly, simple when replacing, efficiency is high, and then has improved significantly the operating efficiency of Vertical Mill complete sets of equipment.
Brief description of the drawings
Further illustrate the present invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of tubular dust-proof cover.
Fig. 2 is the schematic diagram while launching while opening Fig. 1 tubular dust-proof cover slide fastener.
Fig. 3 is the schematic diagram that piston rod of the present invention stretches out state.
Fig. 4 is the schematic diagram of piston rod retracted mode of the present invention.
Embodiment
Referring to Fig. 2, two chain bands 11 and 12 in one secondary slide fastener 1 are separately fixed on two long limits of parallelogram canvas 2, the tubular dust-proof cover 3(that after this slide fastener closes, this parallelogram canvas becomes is referring to Fig. 1), the length of this tubular dust-proof cover is greater than the range of piston rod, and form corrugated tube shape, referring to Fig. 3 and 4, the two ends of tubular dust-proof cover are separately fixed on grinding roller on earrings 5 and oil cylinder 6 with fixture 4.Open slide fastener and the fixture of old tubular dust-proof cover, old tubular dust-proof cover is launched into parallelogram, can directly on piston rod, remove old tubular dust-proof cover; Otherwise, new dust-proof cover can be directly installed on piston rod, in the time changing, do not need to load and unload earrings on grinding roller.
