Problems solved by technology

[0004] The purpose of the present invention is to provide an elevator safety gear and its debugging method, which is convenient for workers to debug the safety gear, and can ensure that the first debugging is qualified. Gaskets are used to adjust the pressure value, which makes the debugging work extremely cumbersome, and when adding or subtracting gaskets, it is difficult to make precise adjustments due to the constant thickness of the gaskets, resulting in errors in the adjustment work

Embodiment 1

[0042] A kind of debugging method of elevator safety gear, its debugging method comprises the following steps:

[0043] (1) Preparation: first place the caliper body on the surface of the equipment operating table, and check whether the parts are complete at the same time, then place a gasket between the fixed brake block and the movable brake block, and push the movable brake block along the direction of the slope Assemblies to press the fixed brake block through the gasket. The parts to be inspected include the caliper body, the fixed brake block assembly, the movable fixed brake block assembly, the needle roller assembly and the butterfly spring group;

[0044] (2) Clamp body fixation: place the safety gear inside the equipment, and align the two hexagonal grooves with the two hexagon head studs on the equipment, then open the longitudinal cylinder and press the clamp body, the pressure of the longitudinal cylinder will Less than the strength of the forceps;

Abstract

The invention relates to the technical field of elevator equipment, and particularly relates to safety tongs for an elevator and a debugging method thereof. The safety tongs comprise a tongs body, a movable brake block, a fixed brake block and an adjusting assembly, wherein the movable brake block is arranged on the right side of the interior of the tongs body; the adjusting assembly is arranged on the right side of the front surface of the tongs body; the adjusting assembly is used in cooperation with the movable brake block; a cavity is formed in the left side of the interior of the tongs body; and the fixed brake block is in sliding connection with the inner wall of the cavity. According to the safety tongs, workers can conveniently debug the safety tongs, moreover, one-time debugging is qualified, so that the debugging operation becomes simple, repeated debugging is not needed, and the problems that the debugging work becomes extremely tedious due to the fact that the adjustment ofthe pressure value of some existing safety tongs for the elevator is realized by increasing or decreasing gaskets in contact with a disc spring, and when the gaskets are increased or decreased, due to the fact that the thickness of the gaskets is certain, accurate adjustment is difficult to make, and errors exist in the adjustment operation are solved.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator safety gear and a debugging method thereof. Background technique [0002] The car elevator has been widely favored by users since its inception. With the rapid development of science and technology in the 21st century, its stability and transportation efficiency have also been continuously updated and improved. The safety of the car elevator depends entirely on the speed limit and safety gear. The elevator safety gear device is under the control of the speed limiter. When the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes, it will stop the car in an emergency and clamp it on the guide rail. A safety device on the It provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. [0003] Some existing safety ...
