Abstract
The utility model discloses a hydraulic adjusting and safety mechanism of a material crusher used in the mining machinery industry. The whole mechanism is composed of a hydraulic cylinder and a hydraulic system. The utility model is characterized in that the mechanism has the functions of hydraulic adjusting and safety. The adjusting of the gape is achieved by the principle of the hydraulic system, and the insurance of the 'exceeding iron' is achieved by a one-way cut-off valve and a pressure reservoir. The synchronous translation of a movable roller is achieved by a balance cylinder. The utility model, an ideal adjusting and safety mechanism of roller crusher, has the advantages of safe operation, long service life, labor and time saving of adjusting and uniform abrasion of a roll ring.
Description
The utility model is a kind of device that is used for mining machinery industry material crusher.
At present both at home and abroad the gape (roller gap) of kibbler roll is adjusted and " crossing iron " (by can not broken thing) insurance institution does not have desirable solution so far in the mining machinery industry.As HAOFIELDS company, the EDGAR ALLEN company of Britain, the WEDAG company of West Germany, KLEEMANN company, the MA of the Soviet Union

The adjustment and the insurance institution of the various kibbler rolls that OPT factory etc. manufactures and designs generally all adopt spring and mechanical mechanism.The gape adjustment of the kibbler roll that China Shenyang Heavy Machinery Plant, Shanghai Heavy Machinery Plant, oil field mountain, river, Sichuan Machines Plant, packet header machinery plant etc. manufacture and design and " crossing iron " insurance institution also adopt artificial adjustment and spring insurance institution.When adjusting gape, no matter this mechanism is with manually or with machinery adjustment getting up not only to require great effort but also take merit, also dangerous, mechanical oscillation of spring insurance institution and noise are big, and the other strength of live bearing or get stuck when " cross iron " is big to the destruction of frame, the wearing and tearing of roller shell are inhomogeneous, life-span is low, and therefore, development hydraulic pressure adjustment and insurance institution are new problems anxious to be solved both at home and abroad always on kibbler roll.
The purpose of this utility model be exactly for provide a kind of have lowering and work-saving, easy and simple to handle, machine run steadily, hydraulic mechanism can realization activity roller synchronous translation, " crossing iron " time do not cause the other strength of live bearing or get stuck, the roller shell wearing and tearing evenly, the hydraulic pressure adjustment and the insurance institution of kibbler roll that can prolong the service life of roller shell.
The utility model is achieved in that entire mechanism is by two most of compositions, the one, the hydraulic cylinder part, there are four groups for four-roller crusher, there are two groups for double-roll crusher, hydraulic cylinder is a combination cylinder, the front portion is a compensating cylinder, and the rear portion is for promoting cylinder, and the centre all separates with toroidal membrane.Another is a hydraulic system, mainly is made up of fuel tank, hydraulic pumping unit, valve group, accumulator, Pressure gauge.Main points of the present utility model are its hydraulic cylinder structure and hydraulic system principle.
The hydraulic pressure adjustment of kibbler roll and insurance institution be with hydraulic oil as power, the hydraulic pressure adjustment is to be realized by the hydraulic pumping unit DFF Direct Fuel Feed, and insurance is to realize by the accumulator and the one-way throttle valve that charge into certain pressure nitrogen in advance.Its operation principle and method of operating are: hydraulic pumping unit starts, hydraulic oil enters reversal valve by check valve, reversal valve is pushed promote forward to the direction of roller, make hydraulic oil enter the hydraulic system of forming by stop valve, Pressure gauge, accumulator and one-way throttle valve, and enter the promotion cylinder.During the roller operate as normal, the size of crushing force mainly is to adjust by the size that changes hydraulic fluid pressure.According to the material condition, adjust the force value of high-pressure overflow valve by needed crushing force size, close stop valve after reaching definite value, system is in packing state, and hydraulic pumping unit just can quit work.When needs roller gap by greatly when ditty is whole, reversal valve pushes promote forward the roller direction to, the hydraulic oil of being discharged by hydraulic pumping unit enters the back cavity that promotes cylinder, makes plunger drive roller translation forward, and roller gap is diminished.When needs roller gap by little during to big adjustment, reversal valve pushes promote backward the roller direction to, the hydraulic oil of being discharged by hydraulic means enters the ante-chamber that promotes cylinder, makes plunger drive roller translation backward, makes roller gap become big.When " crossing iron " appears in broken material, " crossing iron " passes roller backward, the hydraulic oil that promotes the cylinder back cavity enters accumulator fast through one-way throttle valve, the hydraulic oil of compensating cylinder back cavity enters the ante-chamber of another compensating cylinder simultaneously, can realize that like this roller is synchronously parallel mobile, thereby realize the buffering safety effect.After " crossing iron ", by the pressure recovery normal operating conditions of accumulator.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is the hydraulic system principle figure of four-roller crusher in the utility model.
Fig. 2 is hydraulic system arrangements of elements figure.
Fig. 3 is hydraulic cylinder structure figure.
Fig. 4 is the four-roller crusher outline drawing.Fig. 5 is the vertical view of Fig. 4.
With reference to accompanying drawing: fuel tank 1 is a casing that is welded with steel plate in the hydraulic system, and a support plate 38 is welded in the side, and hydraulic pumping unit 2 usefulness screws 39, nut 40, packing ring 41 are fixed on the support plate 38.Hydraulic pumping unit 2 outlets connect check valve 3 with pipeline, one the tunnel connects overflow valve 4 with pipeline, one the tunnel connects reversal valve 5 with pipeline, connect stop valve 6 with pipeline, one the tunnel connects high-pressure overflow valve 7 with pipeline, one the tunnel connect to promote cylinder 10 with pipeline, is connected Pressure gauge 12, accumulator 8 and one-way throttle valve 9 with pipeline between stop valve 7 and the promotion cylinder 10.Hydraulic cylinder is will promote cylinder 10 and compensating cylinder 11 both ends flanges put together on together with screw 20, nut 21, packing ring 22, separate with toroidal membrane 32 in the middle of two cylinders, sealing mutually, toroidal membrane 32 is equipped with sealing ring 19 and 31, promote in cylinder 10 and the compensating cylinder 11 plunger 37 to be housed, 37 1 of plungers are equipped with two half-round clamping rings 29, fix snap ring 29 tight with screw 27, nut 28, plunger 37 other ends are equipped with spherical top 36, are fixed on the movable axis bearing 13 by semicircle shelves ring 26 usefulness screws 24, packing ring 25.Fairlead 35 is equipped with in compensating cylinder 11 ends, and is fixed on the compensating cylinder 11 with screw 34.Fairlead 35 is equipped with sealing ring 23.
Among the figure: the 14-pull bar; The 15-stationary roll; The 16-belt; The 17-motor; The 30-sealing ring; The 33-nut; The 18-decelerator;
Hydraulic pressure adjustment and the insurance institution of kibbler roll compared with prior art have system and simple in structure, volume is little, weight is light, and control is convenient, and handling safety is reliable, cost is low, can realization activity roller synchronous translational, adjust laborsaving province merit, do not cause the other strength of live bearing when " crossing iron " or get stuck, the roller shell wearing and tearing are even, and the life-span is long. This equipment will improve forward a step to the technology of kibbler roll in the mining machinery industry, will be widely used in the mining machinery industry.
