And a lubricating material is coated on the surface of the horizontal steel plate, which is in contact with the support upright post.

The four limiting devices are respectively arranged on four pit walls of the elevator foundation pit, and the limiting surface of each limiting device is over against the side edge of the bottom plate of the elevator shaft and over against the middle part of the side edge of the bottom plate.

The stopper comprises a limiting rod and a second rubber layer, one end of the limiting rod is embedded in the foundation pit wall of the elevator shaft, the second rubber layer is clamped between two vertical clamping plates, one clamping plate is fixed to the other end of the limiting rod, and the outer side plate surface of the other clamping plate is the limiting surface of the stopper.

The four supporting columns are uniformly distributed at four corners of the bottom of the elevator shaft.

And a rubber dust cover is arranged on the supporting upright post in a penetrating manner and is covered at the contact position of the supporting upright post and the horizontal steel plate.

The utility model discloses bottom at the elevartor shaft sets up the support post, the support post keeps sliding contact with the basement of elevator foundation ditch, set up rubber ball support between elevartor shaft and elevator foundation ditch for the elevartor shaft can freely remove in controllable horizontal displacement scope, help increasing the stability of elevartor shaft, and can make the elevartor shaft avoid leading to the fact the structure to destroy because of the displacement is too big under seismic action, the reliability of elevartor shaft has been improved, and help reducing the arrangement of reinforcement rate of the elevator wall of a well, thereby reduce the cost of the elevator wall of a well. In addition, even the elevartor shaft rocks greatly under the earthquake effect, because the setting of stopper, can play the effect of buffering to the elevartor shaft, prevent that the elevartor shaft structure from taking place to destroy.
