The top for stating upper connecting rod is connected with the upper shift mechanism for being lifted upwards, the bottom of the lower pull bar with lifted downwards
Lower shift mechanism is connected, and the left-hand end of the left connecting rod is connected with the wheel shaft of braked wheel, and the right flank of the breaker slot is indent
Arcwall face, the right side of the caliper arranges bearing plate, and the right-hand end Jing fixing axles of the right connecting rod are connected with bearing plate, so that institute
State shift mechanism/lower shift mechanism upwards/it is lower when pulling corresponding pull bar, the right-hand end of left connecting rod upwards/bottom offset, drive system
Driving wheel is rolled in breaker slot to up/down, the setting in arc shaped inside face cause braked wheel to breaker slot two ends move when gradually with
Elevator brake guide rail in breaker slot contacts, until stuck, lift car is static, stops rising/falling.
The technique effect of utility model：（1）Elevator of the present utility model, its two-way instantaneous safety tongs for adopting, relative to
Prior art, is fixedly linked using the bottom girder or back timber of the mounting seat and lift car that are made up of longitudinally mounted plate, gripper shoe, is kept away
Exempt to increase junction steel plate thickness, effectively reduce lift car weight；（2）The inwall coating polytetrafluorethylecoatings coatings of breaker slot,
Increase breaker slot lubricity, while antirust, increases the service life.
