Abstract
The invention discloses a safety device of a servo brake adjusting mechanism, which aims to overcome the disadvantage of the abrasion of a brake block caused by long-time use in the conventional servo brake. The safety device is arranged on an eccentric wheel adjusting mechanism passing through a connecting shaft between a main brake block and a secondary brake block. The safety device is characterized in that the secondary brake block is provided with a hole, a bolt shaft is placed in the hole, the bolt shaft passes through a brake shell and is fixed with a connecting plate through a nut, and the other end of the connecting plate is provided with a hole and is in clearance fit with the connecting shaft. By losing the nut, a shaft cover can be pulled to adjust the distance between the main brake block and the secondary brake block. Through the improvement on the servo brake adjusting mechanism, the structure of the adjusting mechanism on the servo brake is more reasonable and mature, safer, more reliable and longer in service life.
