Abstract
The utility model discloses a special vibration damper of elevartor shaft includes a damping assembly at least, but a damping assembly includes bottom plate, the fixed mobile jib that sets up on the bottom plate and overcoat in mobile jib and relative movement's sleeve, and still including setting up the first shock -absorbing spring in the sleeve, first shock -absorbing spring both ends are supported respectively and are ended on mobile jib top surface and sleeve diapire, the setting in the elevartor shaft, when elevator whereabouts out of control, elevator bottom at first with the sleeve contact, the sleeve pushes down, produce buffering effect through setting up first damping spring compression between mobile jib top surface and sleeve diapire, to the elevator bottom cushioning the damping, simple structure, the installation easily, and the damping is effectual.
Description
Technical field
The utility model relates to elevator damping technology, particularly a kind of elevator shock attenuation unit.
Background technology
Elevator is as a kind of special equipment and be widely used in social multiple field, provides efficient transportation services.The safety performance of elevator, riding traveling comfort are substantially the most also most important indexs.Existing elevator, because user is based on the restriction of cost, the safety control of elevator is used inferior materials and turned out substandard goods, and the safety misadventure that used during elevator falling causes casualties often occurs.When elevator whereabouts out of control, lift car can collide with the shock attenuation unit of elevator lower end, and lift car can cause strong vibration due to rigid shock, and elevator is damaged, and occupant is injured.
Therefore, need to provide a kind of elevator special shock attenuation unit, be arranged in elevator, for when elevator downslide out of control to its vibration damping, buffering sinking speed, avoids rigid shock, plays the effect of safety guard-safeguard.
Utility model content
In view of this, the utility model provides a kind of elevator special shock attenuation unit, is arranged in elevator, for when elevator downslide out of control to its vibration damping, buffering sinking speed, avoids rigid shock, plays the effect of safety guard-safeguard.
The special shock attenuation unit of elevator of the present utility model, at least comprise the first damping assembly, described first damping assembly comprises base plate, is fixedly installed on the mobile jib on base plate and is coated at mobile jib and relatively-movable sleeve, also comprise the first damper spring be arranged in sleeve, described first damper spring two ends are respectively to terminating in mobile jib end face and collet base wall.
Further, also comprise second damping assembly of working in coordination with vibration damping with the first damping assembly, described second damping assembly comprises vibration isolation rubber body, pressing plate and is arranged on the second damper spring between base plate and pressing plate, vibration isolation rubber is external is placed on sleeve, described second damper spring along the circumferential direction arranges at least two around mobile jib, and described pressing plate is coated at mobile jib in relatively-movable mode and is tightly resisted against bottom vibration isolation rubber body under the effect of the second damper spring.
Further, on base plate and described pressing plate, correspondence is provided with spring positioning seat.
Further, sleeve is T-shaped structure, and vibration isolation rubber body is pressed in pressing plate by the end plate of sleeve.
The beneficial effects of the utility model: the special shock attenuation unit of elevator of the present utility model, be arranged in elevator, when elevator whereabouts out of control, bottom elevator first with barrel contacts, sleeve is pressed down, is compressed by the first damper spring be arranged between mobile jib end face and collet base wall and produce buffering effect, buffer shock-absorbing is carried out to bottom elevator, structure is simple, installs easily, and good damping result.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Fig. 1 is the utility model structural representation, as shown in the figure: the special shock attenuation unit of elevator of the present embodiment, at least comprise the first damping assembly, described first damping assembly comprises base plate 1, is fixedly installed on the mobile jib 2 on base plate 1 and is coated at mobile jib 2 and relatively-movable sleeve 3, also comprise the first damper spring 4 be arranged in sleeve 3, described first damper spring 4 two ends are respectively to terminating on mobile jib 2 end face and sleeve 3 diapire; Wherein, base plate 1 is fixedly installed in elevator, and sleeve 3 is inverted structure, is inserted in, sleeve 3 is arranged defining flange 5, mobile jib 2 is provided with positioning plate 6, prevent from coming off from mobile jib 2 top, and in addition, mobile jib 2 top is also provided with spring radius stay 7, for location.
In the present embodiment, also comprise second damping assembly of working in coordination with vibration damping with the first damping assembly, described second damping assembly comprises vibration isolation rubber body 8, pressing plate 9 and is arranged on the second damper spring 10 between base plate 1 and pressing plate 9, vibration isolation rubber body 8 is coated at sleeve 3, described second damper spring 10 along the circumferential direction arranges at least two around mobile jib 2, and described pressing plate 9 is coated at mobile jib 2 in relatively-movable mode and is tightly resisted against under the effect of the second damper spring 10 bottom vibration isolation rubber body 8; When the lower pressure of sleeve 3 bottom elevator moves downward, suppressing action is produced to vibration isolation rubber body 8 and the first damper spring 4 groups simultaneously, vibration isolation rubber body 8 moves down the second damper spring 10 generation effect, like this, first damping assembly and the second damping assembly just produce damping of vibrations simultaneously, synergy is good, and, compact conformation.
In the present embodiment, on base plate 1 and described pressing plate 9, correspondence is provided with spring positioning seat 11.
In the present embodiment, sleeve 3 is T-shaped structure, and vibration isolation rubber body 8 is pressed in pressing plate 9 by the end plate 12 of sleeve 3.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
