Abstract
The invention discloses an anti-falling and anti-overspeed trapper of an elevator mechanism. The anti-falling and anti-overspeed trapper of the elevator mechanism solves the problems that an anti-falling mechanism arranged on an existing vertical lifting mechanism has a complicated structure and occupies too much space. A wedge groove is formed in the upper part of a rectangular groove, a wedge block (9) which is smaller on the upper part and bigger in the lower part is connected to the lower part of the wedge groove in a hanging mode, an L-shape wedge block drag hook (10) is arranged at the lower end of the wedge block (9) which is smaller on the upper part and bigger in the lower part, when the lifting mechanism descends in a stall mode, a suspension loop (11) arranged on the end part of a rotating shaft (12) comes away with the L-shape wedge block drag hook (10) in a hook mode, after the lower end of the wedge block (9) which is smaller on the upper part and bigger on the lower part loses traction, a spring (8) pushes the wedge block (9) which is smaller on the upper part and bigger on the lower part to move upwards relative to a lifting base seat (1), the wedge block (9) which is smaller on the upper part and bigger on the lower part enters the wedge groove formed in the upper part of the lifting base seat (1) and is subjected to clamping stagnation on the lifting base seat (1) together with a lifting guiding rail (7). The anti-falling and anti-overspeed trapper of the elevation mechanism is installed independently, does not need a power source, and is sensitive in reaction and simple and convenient in maintenance.
