Description
Technical field
The invention belongs to technical field of elevator equipment, especially integral type dual-gripper lower beam component of elevator car.
Background technique
Existing elevator car frame generally all erects beam by a car frame underbeam and two sedan-chairs and constitutes, and wherein car frame underbeam is horizontal
The bottom of lift car is set, the entire car weight of carrying is mainly played a part of, it determines the stability of an elevator,
Underbeam both ends are ipsilateral to be symmetrically arranged with two car floor wheels, and car floor wheel is mounted on underbeam by a wheel shaft.
In this tradition car floor wheel mounting means, wheel shaft is installed in cantilever fashion, under elevator in the prior art
Beam assembly is all much to use to add mounting base below underbeam weldment and install car floor wheel using cantilever.This structure allows elevator to exist
Comfort is bad when actual motion, due to car floor wheel cantilever, causes the unilateral stress of car floor wheel shaft, radial discontinuity causes
Extra bounce is generated when wheeling thereof, cantilever installation wheel shaft is caused to shake, and after long-time use, the wheel shaft of cantilever installation can also go out
It now deforms, seriously affects elevator operation stability, be especially even more to cause eccentric force excessive so that pacifying in heavy-duty elevator
The following overall deformation of seat is filled, influences the normal operation of elevator, and very inconvenient when installation and later maintenance are replaced, maintenance
Replacement frequency is high, because using cantilevered to install so that car floor wheel shaft needs to increase on one side additional nut and buckle and fixes, prevents
Only wheel body moves on one side partially, so wheel shaft is difficult to be aligned when passing through mounting base, also because removing buckle when later maintenance is replaced
It is time-consuming and laborious, it there is a problem that maintenance replacement frequency is high, stability is poor, safeguard inconvenience, therefore be badly in need of to existing shallow bottom
The car floor structure in hole improves.
