At present, general elevator buffer device is made up of single spring bumper or energy-consuming hydraulic buffer, is arranged on the bottom of elevator hoistways.Due to elevator in case of a fault free fall to producing huge impulsive force during bottom; if alleviated when lift car freely falls to the end, hole for the injury of human body; key is that the energy dissipation impact energy of car being converted into other is fallen; transformation is more large faster; effect for protecting human body is better, also just can better save life.The buffer protection function that existing elevator pit bottom buffering device can play is limited, large not to the protective effect of human body.Meanwhile, adopt spring bumper or energy-consuming hydraulic buffer may lose efficacy under huge impulsive force, the object consuming impact energy can not be played well.
Utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of buffer capacity strong, additional energy source can not be consumed, buffer protection base when safe and effective failure-free vertical lift elevator falls.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise top panel, guiding mechanism, hydraulic damping device, base plate, hydraulic protector, intermediate plate; guiding mechanism and hydraulic damping device are through the hole that intermediate plate is arranged; two ends are fixedly connected with top panel, base plate respectively; the hydraulic actuating cylinder urceolus of described hydraulic damping device and intermediate plate are welded and fixed, and are connected with hydraulic protector through oil pipe.
Described buffer protection base also comprises four cycle side plates; described four cycle side plates and base plate are connected to form body structure; described top panel, intermediate plate in casing along guiding mechanism up-and-down movement; four limits of described intermediate plate are enclosed with the wear resistant rubber circle increasing friction drag; strengthening the friction of described intermediate plate and four cycle side plates, is that heat energy dissipates by the kinetic transformation of a part.
Described hydraulic damping device is made up of upper and lower two energy-dissipating type hydraulic dampers; perfusion liquid force feed in described hydraulic actuating cylinder urceolus; sealed by piston rod, seal ring and end cap; be provided with spring between described piston rod and end cap, described hydraulic oil circulates in hydraulic damping device and hydraulic protector through oil pipe.
In the middle of casing, multiple hydraulic damping device is set, described hydraulic damping device up-and-down movement will be driven when car freely falls and contacts with top panel, upper and lower two energy-dissipating type hydraulic dampers move simultaneously, are that the heat energy of hydraulic oil dissipates by kinetic transformation; Each hydraulic damping device arranges a hydraulic protector, avoids damaging hydraulic damping device and the hydraulic oil supplementing loss when car produces huge impulsive force when very high height falls.
Described spring is the nonlinear spring of stiffness index variation, as resilience and energy storage equipment.
The utility model can improve elevator have an accident free falling with hole the end contact time produce the buffer capacity of impacting; thus the personal safety of elevator passenger can be protected better, in a big way, the impact energy of car can be converted into heat energy and other forms of energy dissipates by fast speed.Because this device is arranged on shaft bottom, the quality for car does not increase, and therefore additionally can not consume the energy, can also provide buffering for the normal operation of elevator.

Detailed description of the invention
As shown in Fig. 1,8, buffer protection base when vertical lift elevator of the present utility model falls comprises top panel 1, guiding mechanism 2, hydraulic damping device 3, base plate 4, hydraulic protector 5, intermediate plate 6 and four cycle side plates 7.Arrange some guiding mechanisms 2 and hydraulic damping device 3 in the middle of top panel 1 and base plate 4, and be weldingly connected by the hydraulic actuating cylinder urceolus 35 of intermediate plate 6 with hydraulic damping device 3, intermediate plate 6 is reserved circular hole and is facilitated guiding mechanism 2 up-and-down movement in the position of guiding mechanism 2 simultaneously.
As shown in Figure 2, guiding mechanism 2 comprises guide pillar 22 and guide pillar guide pin bushing 21, the bottom of guide pillar 22 is connected with base plate 4, and the top of guide pillar guide pin bushing 21 is connected with top panel 1, and guide pillar 22 moves back and forth and ensures that the relative motion between top panel 1 and base plate 4 occurs in vertical direction in guide pillar guide pin bushing 21.
As Fig. 3, 4, shown in 5, hydraulic damping device 3 is in series by two energy-dissipating type hydraulic dampers, the hydraulic actuating cylinder urceolus 35 of hydraulic damping device 3 is set to two open ends form, adopt seal ring 34, hydraulic oil 36 is sealed in hydraulic actuating cylinder urceolus 35 by end cap 33 and piston rod 31, the top of piston rod 31 is connected with top panel 1 or base plate 4 respectively, between piston rod 31 and end cap 33, adopt the nonlinear spring of stiffness index variation as resilience and energy storage equipment, multiple fluid cutoff port 38 is set on piston 37 simultaneously, when utilizing piston 37 to move back and forth in oil cylinder, hydraulic oil 36 at a high speed produces friction by kinetic transformation for heat energy reaches the object of buffering by cutoff port 38.
As shown in Figure 6, hydraulic protector 5 comprises fuel tank 51, by pass valve 52, flow regulating valve 53, oil pipe 54, wherein fuel tank 51 is fixed on base plate 4, in two oil cylinders, aperture 55 and aperture 56 is had in the middle part of hydraulic actuating cylinder urceolus 35, when the impulsive force that piston rod 31 is subject to is excessive, hydraulic oil 36 flows into fuel tank 51 by aperture 55 and by pass valve 52, when piston rod 31 move back and forth in hydraulic actuating cylinder urceolus 35 hydraulic oil 36 spill time, hydraulic oil 36 enters two oil cylinders by flow regulating valve 53 and aperture 56 and supplements hydraulic oil 36, thus achieve respectively under normal circumstances with the protection of hydraulic damping device 3 in large impact situation.
As shown in Figure 7, intermediate plate 6 and hydraulic actuating cylinder urceolus 35 are welded and fixed, reserve circular hole 62 in the position of guiding mechanism 2 simultaneously, circular hole 62 is not connected with guide pillar guide pin bushing 21, guaranteeing that the sense of motion of hydraulic damping device 3 when shaking back and forth is vertical direction, guaranteeing that hydraulic actuating cylinder urceolus 35 and intermediate plate 6 move in the vertical direction simultaneously.Intermediate plate 6 is slightly less than top panel 1, and its periphery parcel wear resistant rubber circle 63 increases top panel and the friction force of hydraulic damping device 3 when shaking back and forth up and down between intermediate plate 6 and four cycle side plates 7, increases energy consumption effect.
