Make portion's external diameter.
Preferably, also include braking mechanism, the braking mechanism includes brake and brake lever, the brake with
Main shaft connects, and the brake lever is connected with the brake.
This utility model beneficial effect：
The auxiliary brake provided in this utility model includes electric magnet, banking pin and resetting-mechanism, wherein resetting
Mechanism be located at electric magnet on, when electric magnet is obtained it is electric when by banking pin attract move downward, and banking pin extruding elastic mechanism, due to
The captivation of electric magnet is more than the restoring force of elastic mechanism, therefore banking pin will not stop the normal work of chain；Work as electric magnet
During dead electricity, electric magnet is zero to the captivation of banking pin, and now elastic mechanism restoring force promotes banking pin is stuck in banking pin
In chain gap, and then it is prevented from the staircase car slipping after braking.
The staircase with anti-slip mechanism of car that this utility model is provided, can make anti-slip machine in the case of elevator dead electricity
Structure works elevator brake, the safety of further protection elevator user, especially can go wrong in the braking mechanism of elevator
When, effectively by elevator brake.
