Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Such as Figure 2-4 As shown, a detection device for the lifting force of the safety gear includes an electronic tension gauge 1, and the pull ring of the electronic tension gauge 1 is connected with a suspension assembly for connecting the lifting pin 2 of the safety gear;

[0030] The top of the electronic tension gauge 1 is connected with a positioning bracket 3 , and the positioning bracket 3 includes a clamping assembly for connecting with the top of the lower beam linkage shaft fixing plate 4 .

[0031] Specifically, during the test, the lifting force of the suspension assembly on the lifting pin 2 connected to the safety gear is the tension force of the wire rope simulating the speed governor, wherein the tension force must not be less than the larger value of the following two values ...

Abstract

The invention relates to the technical field of safety tongs of elevators, and in particular relates to a device for detecting pulling force of safety tongs. The device comprises an electronic tension meter, wherein a pull ring of the electronic tension meter is connected with a hanging assembly for connecting a lifting pin of the safety tongs; the electronic tension meter is connected with a positioning bracket; and the positioning bracket comprises a clamping slot connected with the top of a lower beam linking shaft fixing plate in a clamping manner. According to the device for detecting the pulling force of the safety tongs, a measurement mod and a reference are unified, namely that the upward lifting height and the lifting direction are fixed, and the error rate is low; measurement of data is more precise, so that the reliability of a product is guaranteed; and furthermore, the device is simple and convenient to operate, and a worker does not need to perform lifting operation for a long time, so that the measurement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of elevator safety gear, in particular to a detection device for lifting force of the safety gear. Background technique [0002] In the elevator structure, the safety gear is a mechanical device that stops the movement of the elevator car, and the speed limiter is a device that limits the speed of the elevator car, and the combined action of the safety gear and the speed limiter works. [0003] Specifically, when the car overspeeds, the overspeed governor acts, and the friction force generated by the tension of the overspeed governor steel wire rope makes the overspeed governor steel wire rope pull up the lifting point of the safety gear, pull up the wedge block of the safety gear, and pass through the wedge clamp Hold the guide rail to stop the car. [0004] In order to prevent the misoperation of the safety gear when the elevator is in normal operation, a torsion spring is provided to keep the wedge posit...
