Abstract
The invention discloses a motor burndown preventing device for a hoisting machine. A gearbox is arranged between the motor and a driving shaft. A set of fixed blocks is fixed to one end of the driving shaft. A set of transmission blocks is fixed to one end, which faces the fixing blocks, of a driven shaft. Each transmission block has a hollow structure. Furthermore the inner part of the transmission block is connected with a set of connecting shafts which are inserted into the inner part of the transmission block through gear teeth. A set of movable blocks is fixed to one end of the connecting shafts. One end surface, which faces the fixed blocks, of the movable blocks is provided with a plurality of sets of spacing rods. Furthermore the angles and distances among the plurality of sets of spacing rods are same. One end surface, which faces the movable blocks, of the fixed blocks is provided with a plurality of sets of trough structures.
