The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 to Fig. 5, high-speed hydraulic energy disperser of the present utility model, comprises cylinder component 1, plunger assembly 2, thread ending cover 3, retracing spring 4, control group 5, rubber collision block 6 and switch guide rod 7, wherein:
Cylinder component 1 comprise can topping up force feed oil cylinder body 10, be sealed on oil cylinder body 10 lower end base plate 11 and be located at the inner chamber central authorities of oil cylinder body 10 and be fixed on the control stalk 12 on base plate 11; On the top casing wall of oil cylinder body 10, radially offer an oil hole, on this oil hole, connect successively a liquid airproof circle 13, an elbow 14, a plug screw 15 and an oil measurer 16;
The internal chamber wall of thread ending cover 3 is the smooth face of cylinder, and outside face is provided with the outside thread that the negative thread that arranges with the inner cavity surface top of oil cylinder body 10 is connected; Between thread ending cover 3 and oil cylinder body 10, O-ring seals 31 is set;
Plunger assembly 2 comprises plunger body 20 and is fixed on correspondingly upper cover and the lower cover 25 of the upper and lower port of plunger body 10; Upper cover comprises upper cover plate 21, filtering net 22, inner cover plate 23 and the L-square 24 connecting successively, and this inner cover plate 23 is provided with deflation hole; The end face central authorities of lower cover 25 offer a tapered joint discharge orifice 26; The lower seal ground of this plunger assembly 2 enters the inner chamber of oil cylinder body 10 through thread ending cover 3, the control stalk 12 in cylinder component 1 is inserted in the cutoff port of lower cover 25, and plunger assembly 2 can be along control stalk 12 up-and-down movements.Seal ring 32 and dust ring 33 are also set between plunger assembly 2 and thread ending cover 3; One cover 27 is also set on plunger assembly 2;
Retracing spring 4 is sleeved in plunger body 20 by a spring seat of honour 40 that is arranged on plunger body 20 upper ends;
Control group 5 comprises and is arranged on the switch bracket 51 on oil cylinder body 10 tops and the travel switch 53 on switch bracket 51 is installed; Switch bracket 51 is arranged on the top of oil cylinder body 10 by an annular anchor ear 52;
Rubber collision block 6 is arranged on the upper end of the upper cover plate 21 of plunger assembly 2;
The upper end of switch guide rod 7 is fixed on the upper end of plunger body 20 and is plugged on movably in the guide groove of offering on switch bracket 51 by a upper bracket 70, to keep straight-line motion and trigger the contact push rod of travel switch 53 when moving down, travel switch 53, to outer lateral buckling one angle of the contact push rod of travel switch 53, is not triggered in the lower end of this switch guide rod 7 when energy disperser is not worked.
At plunger assembly 2, enter after oil cylinder body 10, the hydraulic oil in compression cylinder body 10 inner chambers, makes hydraulic oil by the tapered joint discharge orifice on lower cover 25, enter the inner chamber of plunger body 20.
The principle of work of high-speed hydraulic energy disperser of the present utility model: water bumper is by four through holes on the base plate 11 of cylinder component 1, is fixed on swell fixture on the poor steel of pit of car or in concrete foundation; When car or counterweight cushion at collision, plunger assembly 2 moves downward, hydraulic oil in compression cylinder body 10, the kinetic energy of elevator is passed to hydraulic oil, make hydraulic oil by the tapered joint discharge orifice 26 on lower cover 25, spray to the inner chamber of plunger body 20, when hydraulic oil passes through the tapered joint discharge orifice 26 on lower cover 25, because flow area is more and more less, increasing by the damping of liquid, form eddy current, make particle in hydraulic oil collide with each other, rub and produce heat the impact kinetic energy of elevator is consumed, thereby guarantee elevator safety failure-free ramp to stop.When energy disperser resets, the potential energy of retracing spring 4 discharges, and plunger assembly 1 bounce-back upward movement, retracts the oil of outflow in oil cylinder body 10, and this reset time is no more than 120s, requires electric demo plant checking simultaneously.
The upper cover of plunger assembly 2 is to integrate exhaust and filtering installation, has save the many parts of front cleaning are installed, deposited the problems such as loose, has improved production efficiency; By effective filtration of filtering installation, prevent leaking outside of hydraulic oil simultaneously, caused the problem of environmental pollution.The attaching parts of plunger assembly 2 and cylinder component 1---thread ending cover 3 is to integrate orienting sleeve, axle sleeve, attaching parts, has saved two dot structure forms that axle sleeve in the past adds orienting sleeve; Liquid airproof circle and static O-ring seals are housed on thread ending cover 3, in order to avoid hydraulic oil leaks, cause environmental pollution.The main driving power of travel switch 53 major control, in order to avoid the actuating device that has been out of order is also in work.
The working process of high-speed hydraulic energy disperser of the present utility model: the stop of inertia impact → rubber impact head → water bumper (the braking) → stall car of stall car.Rubber collision block 6 can bear the inertial impaction that car out of control is huge, and the inertia kinetic energy of car out of control is passed to water bumper.This device moves down when bearing shock, compression hydraulic energy disperser.Hydraulic oil now, in oil cylinder body 10, becomes high pressure chest, in plunger body 20, becomes low-pressure cavity, therefore can flow to from the inner chamber of oil cylinder body 10 inner chamber of plunger body 20.Control stalk 12 in oil cylinder body 10 can be controlled hydraulic oil by the tapered joint discharge orifice 26(damping hole on lower cover 25) the effect that moves downward to reach even deceleration of flow (throttling).Buffering course when car clashes into water bumper is apparent, and then under stall car continuous action, hydraulic oil, from flow to the inner chamber (throttling work done) of plunger body 20 in oil cylinder body 10 by tapered joint discharge orifice 26, now can produce a large amount of heats.This process is the process of water bumper work done, the process that consumes stall car inertia kinetic energy.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
