Description
Technical field
the utility model relates to the elevator safety base of a kind of elevator cushion base, particularly a kind of high security.
Background technology
current, elevator increases with skyscraper, popularizes gradually, because elevator is manned equipment; its safe in operation is significant, although elevator has done a lot of measure at secure context, still has fall event to occur; for protection personal safety, in support safety measure, elevator cushion base is essential.Elevator cushion base is that one is arranged on shaft bottom, for the device preventing lift car from damaging because of contact bottom all standing.At present, conventional elevator cushion base cushions only by a spring, and buffering effect is poor, easily damages buffering plate, also can produce larger safety misadventure when elevator impulsive force is excessive.
Utility model content
the purpose of this utility model is, provides a kind of elevator safety base.The utility model has the advantages that anti-impact force is strong and safety is high.
the technical solution of the utility model: elevator safety base, it is characterized in that: comprise pedestal, pedestal is provided with dash pot, is vertically provided with big spring in dash pot, is provided with little spring in big spring, big spring is arranged with little spring is concentric, little spring upper end is provided with shifting axle, and the middle part of described dash pot is provided with through hole, and the top of described shifting axle extends to dash pot outside through through hole, the bottom of shifting axle is provided with collar stop, and the diameter of collar stop is not less than the external diameter of big spring; The upper end of described shifting axle is provided with steel plate, steel plate is provided with successively foamed plastic layer and buffering rubber layer from bottom to top.
in aforesaid elevator safety base, between described steel plate and shifting axle, be welded with boss.
compared with prior art, the utility model is by being arranged on shaft bottom by pedestal, time when elevator declines close to shaft bottom, pushing down steel plate makes shifting axle move down, thus compression little spring, little spring produces antagonistic force to car, then by being provided with foamed plastic layer and cushioning rubber layer on steel plate, antagonistic force is produced to car, finally by big spring, antagonistic force is produced to car, realize multi-buffer effect, good buffer effect, can bear large impact power, anti-impact force is strong, not fragile, thus avoid potential safety hazard, safety is high.The utility model also has implements simple, the easy to use and lower-cost feature of structure.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-little spring, 2-dash pot, 3-steel plate, 4-foamed plastic layer, 5-yielding rubber layer, 6-through hole, 7-collar stop, 8-shifting axle, 9-big spring, 10-pedestal, 11-boss.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.Elevator safety base, form as shown in Figure 1, it is characterized in that: comprise pedestal 10, pedestal 10 is provided with dash pot 2, big spring 9 is vertically provided with in dash pot 2, little spring 1 is provided with in big spring 9, big spring 9 is arranged with little spring 1 is concentric, the height of little spring 1 is less than the height of big spring 9, (height of general little spring 1 is the mid-height of big spring 9), little spring 1 upper end is provided with shifting axle 8, the middle part of described dash pot 2 is provided with through hole 6, the top of described shifting axle 8 extends to dash pot 2 outside through through hole 6, the bottom of shifting axle 8 is provided with collar stop 7, the diameter of collar stop 7 is not less than the external diameter of big spring 9, collar stop 7 is positioned at the top of big spring 9, the upper end of described shifting axle 8 is provided with steel plate 3, steel plate 3 is provided with successively foamed plastic layer 4 and buffering rubber layer 5 from bottom to top.
be welded with boss 11 between described steel plate 3 and shifting axle 8, strengthen Joint strenght.
the utility model is by being arranged on shaft bottom by pedestal, time when elevator declines close to shaft bottom, pushing down steel plate makes shifting axle move down, thus compression little spring, little spring produces antagonistic force to car, then by being provided with foamed plastic layer and cushioning rubber layer on steel plate, antagonistic force is produced to car, finally by big spring, antagonistic force is produced to car, realize multi-buffer effect, good buffer effect, large impact power can be born, anti-impact force is strong, not fragile, thus avoid potential safety hazard, safety is high.
Claims (2)
1. elevator safety base, it is characterized in that: comprise pedestal (10), pedestal (10) is provided with dash pot (2), big spring (9) is vertically provided with in dash pot (2), little spring (1) is provided with in big spring (9), big spring (9) is arranged with little spring (1) is concentric, little spring (1) upper end is provided with shifting axle (8), the middle part of described dash pot (2) is provided with through hole (6), the top of described shifting axle (8) extends to dash pot (2) outside through through hole (6), the bottom of shifting axle (8) is provided with collar stop (7), the diameter of collar stop (7) is not less than the external diameter of big spring (9), the upper end of described shifting axle (8) is provided with steel plate (3), steel plate (3) is provided with successively foamed plastic layer (4) and buffering rubber layer (5) from bottom to top.
