Side wall is connected.
Further, strengthening support is arranged in the lower face of the horizontal mounting plate, and the top surface of the strengthening support is horizontally mounted with described
The lower face of plate is fixedly linked, and the side of the strengthening support is fixedly linked with the support plate, to reinforce the intensity of mounting base.
Further, the pulling apparatus includes upper connecting rod, left connecting rod, right connecting rod and central shaft；The bottom end of the upper connecting rod,
The right-hand end of left connecting rod, the left-hand end of right connecting rod and central shaft are hinged, the top of the upper connecting rod with lifted upwards it is upper
Shift mechanism is connected, and the right-hand end of the right connecting rod is connected with the wheel shaft of braked wheel, and the left side of the breaker slot is imploded arcs
Bearing plate is arranged in the left side in shape face, the caliper, and the left-hand end of the left connecting rod is connected through fixing axle with bearing plate, so that described
When upper shift mechanism pulls up pull rod, the left-hand end of right connecting rod shifts up, and braked wheel is driven to scroll up in breaker slot,
The setting in arc shaped inside face is so that braked wheel gradually connects with the elevator brake guide rail in breaker slot when being moved to breaker slot both ends
It touches, until stuck, lift car is static, realizes braking.
Further, annular knurl reticulate pattern is arranged in the outer surface of the braked wheel, to enhance the braking effect of braked wheel.
The technique effect of utility model：（1）The progressive safety gear that the elevator of the utility model uses, relative to existing skill
Art is fixedly linked using the bottom girder or top beam of the mounting base and lift car that are made of longitudinally mounted plate, support plate, avoids increasing
Junction steel plate thickness effectively reduces lift car weight；（2）The inner wall of breaker slot coats polytetrafluorethylecoatings coatings, increases system
Dynamic slot lubricity, while antirust, prolong the service life；（3）Annular knurl reticulate pattern is arranged in the outer surface of braked wheel, can increase braked wheel
With the friction of elevator brake guide rail, braking effect is improved.
