Embodiment
Below with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model to be described in further detail.
The quick oil return master cylinder of mining monorail hoist of the present embodiment, comprise outer cylinder 1, in outer cylinder 1, be provided with piston rod 2, outer cylinder 1 is inserted in spring 3, spring 3 both sides are provided with gland 7, piston rod 2 right side peripheries are provided with guide sleeve 4, between piston rod 2 and guide sleeve 4, be provided with guide ring 15, guide sleeve 4 peripheries are provided with jam nut 5, piston rod 2 right-hand members are connected with the first jointing seat 8 by two semi-rings 6, the first jointing seat 8 is provided with filler opening 19, piston rod 2 left sides are connected with piston 21, the piston 21 upper and lower both sides of right-hand member are respectively arranged with buffering pressure release nut 10 and one-way valve 11, in piston 21, be provided with fast decompression valve 12, the second jointing seat 22 is installed on the left side gland 7 of spring 3, the second jointing seat 22 is provided with return opening 20, between outer cylinder 1 and guide sleeve 4, be provided with the O RunddichtringO 18 for sealing, between guide sleeve 4 and piston rod 2, be provided with y-type seal ring 16 and dust ring 17, between piston 21 and outer cylinder 1, be provided with piston packing 9, between piston 21 and fast decompression valve 12, be provided with O type circle 13 and circlip 14.
Working principle:
When 1, locomotive opens lock, high pressure liquid force feed enters in oil hydraulic cylinder through filler opening 19, by rod end chamber, from the gentle sluicing of one-way valve 11, press nut 10 to enter right cavity of cylinder, in cylinder, pressure increases, fast decompression valve taper junction plane is under the pressure of highly pressurised liquid, and in sealing state, piston is moved to the left spring-compressed, the lock body being connected with oil cylinder unclamps, and locomotive normally moves;
2, while needing band-type brake, as shown in right side dotted line in figure, filler opening 19 is switched to fuel tank and communicates, now oil pressure is almost equal to zero, rod end chamber internal pressure reduces rapidly, cylinder body right-side cavity internal pressure and rod end chamber form very large pressure difference, now one-way valve 11 is owing to being subject to and piston rod endoporus low pressure, the pressure difference effect of the capable one-tenth of the right chamber of piston high pressure and closing, right chamber high pressure liquid force feed slowly enters piston rod endoporus through buffering pressure release nut, mineralization pressure is poor, under pressure difference effect, fast decompression valve taper junction plane cup type inner core moves to right under pressure difference effect, taper junction plane forms very macrovoid, spring opens rapidly, in-oil cylinder hydraulic oil accelerates oil sump tank through filler opening and return opening, improved master cylinder band-type brake speed,
3, slow braking principle, slowly pressure release in holding state filler opening tightly, make to form very little pressure difference with exocoel in rod end chamber, liquid is postponed, and to press nut to flow to piston rod cavity inner for sluicing, spring starts slowly to stretch out, due to the slightly large flow with cushioning in pressure release nut of filler opening Flow-rate adjustment, in slow pressure leak process, rod end chamber pressure continues to decline, pressure difference increases, force fast decompression valve to be opened, the outer intracavity liquid of piston rod flows in cylinder chamber, left side, and spring is stretched out fast, completes the braking that puts in place.
The unspecified content of the utility model is prior art, and those skilled in the art can obtain inspiration from the present embodiment and prior art, are out of shape and obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
