Abstract

The invention provides an elevator safety gear structure, which belongs to the technical field of safety gear. The elevator safety gear structure includes a first wedge block, a needle roller row, a second wedge block, a lifting rod, a fixing piece, a connecting piece and an expansion extruding piece. The fixing part in the present invention keeps one end of the first wedge block parallel to one end of the guide rail and keeps the distance between them constant, so as to prevent the first wedge block from inclining and prevent the second wedge block from extending into the gap between the first wedge block and the guide rail. In order to stop the first wedge, the connectors respectively rotate the other end of the first wedge and the second wedge to the car, pull the pull rod until the second wedge moves towards the direction close to the first wedge, The expansion extrusion part expands and squeezes the lower end of the second wedge block when it is hit by the lower end of the car, so that the second wedge block moves toward the direction close to the first wedge block, thereby accelerating and pushing the second wedge block toward the first wedge block direction movement, improve the efficiency of braking the car.

Description

technical field [0001] The invention belongs to the technical field of safety gear and relates to an elevator safety gear structure. Background technique [0002] The safety gear is an important safety component in elevator equipment. It is used to stop the car in an emergency and clamp the car on the elevator guide rail when the elevator has faults such as overspeed and broken rope. However, if the car is skewed, the safety gear will also be skewed relative to the guide rail, so the safety gear cannot safely stop the car on the guide rail. [0003] Chinese patent CN209583321U discloses a progressive elevator safety tongs, including two mounting plates, the two ends of the two mounting plates are connected by reinforcing columns, the two ends of the mounting plate are equipped with fixed blocks, and the inner walls of the two fixed blocks are clamped with sliding clamps. The damping plate is installed on the inner wall of the sliding pliers, and the guide plate is installed...
