Description
Technical field
The utility model relates to a kind of express elevators, more particularly, to a kind of express elevator top cushion device.
Background technique
Currently, express elevator up-running over-speed protection is permanent-magnet synchronous host computer host brake to realize.Also some is outer
Adding meter uplink safety tongs adds bidirectional speed limiter linkage to realize up-running over-speed protection.Above-mentioned two scheme, in conventional lift failure
Elevator up-running over-speed protection be effective.But when express elevator uplink full gear is run, the traction of traction machine is insufficient and drags
Draw steel wire iope slippage, again close to top layer leveling, at this moment apparatus failure elevator occurs, and lift car certainly will impact elevator machine with full gear
Room floor, because speed has just been arrived more than normal speed, the not up to speed of limiter of speed movement, uplink safety tongs akinesia, this
When express elevator can with sizable impact force impact elevator shaft floor, enough entire computer room hit to obtain crush.
Utility model content
The purpose of this utility model is to provide a kind of express elevator top cushion devices, to solve prior art high speed
The above problem existing for elevator.
For this purpose, the utility model uses following technical scheme:
A kind of express elevator top cushion device comprising elevator car rack, car frame upper beam assembly, host spandrel girder and
Traction steel-cable, wherein the car frame upper beam assembly is set to the top of elevator car rack, on the car frame upper beam assembly
It is fixed on several and rushes buffer, the host spandrel girder is set to the top of the elevator car rack, is disposed with master thereon
One end of machine, the traction steel-cable is connected on elevator car rack, and the other end is elevator balanced heavy around traction sheave connection, described
The bottom of host spandrel girder is equipped with the top cushion device for the top floor that several are passed down through elevator(lift) machine room, and the top is slow
Rush device and it is described on rush buffer one-to-one correspondence.
Particularly, it is upper fliud flushing compression buffer that buffer is rushed on described, and the upper fliud flushing compression buffer is fixed on lower buffering
On device seat, the lower bumper seat is fixed by bolts in the car frame upper beam assembly.
Particularly, the top cushion device is polyurethane buffering block, and the polyurethane buffering block is fixed on upper bumper seat
On, the upper bumper seat is fixed on buffer bottom beam, and the buffer bottom beam is fixed on the bottom of the host spandrel girder.
Particularly, it rushes buffer on described and there are two top cushion device is respectively provided with, buffer is rushed on two and is symmetrical arranged
Upper bumper seat is installed in the position for rushing buffer on the two sides of the car frame upper beam assembly, two top cushion devices correspondences
On.
Particularly, upper bumper seat is corresponded on floor at the top of the elevator(lift) machine room offer through-hole, the upper bumper seat
Extend downwardly the top floor setting of elevator(lift) machine room.
The beneficial effects of the utility model are that the express elevator top cushion device is in elevator compared with prior art
Have additional buffer unit between car frame and the host spandrel girder at top, lift car surprisingly on rush when, pass through buffer unit
Impact force is absorbed and is consumed, is consumed in elevator oneself internal system, elevator(lift) machine room building will not be damaged.Not only structure
Simply, ingenious in design；And the impact force rushed in carriage can be consumed in elevator interior, improve the safety of express elevator operation
Reliability.
Detailed description of the invention
Fig. 1 is the main view for the express elevator top cushion device that specific embodiment of the present invention provides；
Fig. 2 is the top view for the express elevator top cushion device that specific embodiment of the present invention provides.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of express elevator top cushion device includes elevator car rack
1, car frame upper beam assembly 2, host spandrel girder 3 and traction steel-cable 4, car frame upper beam assembly 2 are set to elevator car rack 1
Top, the two sides of car frame upper beam assembly 1 are symmetrically fixed with two upward upper fliud flushing compression buffers 5, upper fliud flushing compression buffer 5
It is fixed by bolts on lower bumper seat 6, lower bumper seat 6 is fixed by bolts on car frame upper beam assembly 2.
Host spandrel girder 3 is set to the top of the elevator car rack 1 and is located at the upper of the top floor 7 of elevator(lift) machine room
It is square, it is disposed with host 8 on host spandrel girder 3, one end of traction steel-cable 4 is connected on elevator car rack 1, and the other end is bypassed and draged
Running wheel 9 connects elevator balanced heavy by 10, and the bottom of host spandrel girder 3 has been bolted buffer bottom beam 11, buffer bottom beam
11 two sides of the bottom are bolted there are two upper bumper seat 12, are corresponded to upper bumper seat 12 on top floor 7 and are offered
Two through-holes, upper bumper seat 12 are passed down through the through-hole setting on the floor 7 of top, and the bottom of each upper bumper seat 12 passes through
Bolt is fixed with polyurethane buffering block 13, and polyurethane buffering block 13 is correspondingly arranged with upper fliud flushing compression buffer 5.
The working principle of express elevator top cushion device: lift car surprisingly upper punching, due to accident, lift car is more
Elevator car speed is also rushed in full gear when crossing level position.Polyurethane buffering block is hit when being above flushed to upper fliud flushing compression buffer 5
When 13, upper fliud flushing compression buffer 5 and polyurethane buffering block 13 are all compressed, and energy is rushed on lift car and is absorbed and is disappeared by buffer
Consumption.Impulse force (upward) active force of this energy is directed toward upper bumper seat 12；Reaction force (downward) acts on lift crosshead connection
Lower bumper seat 6.It can be seen that the power rushed on lift car, consumes in elevator oneself internal system, will not damage elevator(lift) machine room
Building, will not damage lift facility itself.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes
Change and change is fallen within the scope of the claimed invention.The utility model requires protection scope is wanted by appended right
Ask book and its equivalent thereof.
