Embodiment Construction

[0029] The self-locking reliability performance testing machine of the speed difference type anti-drop device of the present invention comprises a frame 20, an air pump 16, a cylinder 7, a movable plate 4, a release mechanism 5, a sensor (proximity switch) 13, an impact base 1, a weight group 3 and control cabinet11.

[0030] A suspension ring 19 is fixedly connected to the top central suspension plate 8 of the testing machine frame 20 for connecting the speed difference type fall arrester 9 .

[0031] The two fixing plates 10 are symmetrically arranged left and right, and divide the inner space of the frame 20 into upper and lower parts.

[0032] A two-way cylinder 7 is arranged vertically above the two fixed plates. An air rod 21 is respectively arranged in the two-way cylinder 7 . The lower end of the gas rod 21 is fixedly connected to the movable plate 4, and the movable plate 4 moves up and down under the drive of the gas rod 21.

[0033] Two movable plate limit rods 1...

Abstract

The invention discloses a speed-different type safety catcher self-locking reliability performance test machine which comprises a framework, a base plate 2 and an air pump. The framework is provided with two fixed plates, releasing mechanisms, one or two upper stop blocks, an impact pedestal, a control cabinet, a suspension ring, a weight block set, cylinders, movable plates, a sensor, movable plate gag lever posts, and a weight block gag lever post. Each releasing mechanism 5 comprises an electromagnet, a releasing pawl and a lever mechanism. The releasing pawl extends horizontally and inwardly to form a mobile platform capable of supporting the weight block set. The electromagnet and one end of the lever mechanism form a machinery linkage capable of tripping. The impact pedestal is arranged at a central position of the base plate. Center lines of the impact pedestal, the weight block set and the speed-different type safety catcher are superposed. The impact pedestal is provided witha counting sensor. The speed-different type safety catcher self-locking reliability performance test machine has the advantages of simple structure, low manufacture cost, good processing consistency,suitability of mass production and the like.

Description

technical field [0001] The invention relates to a test device for the fatigue performance of a speed difference type fall arrester. Specifically, it is a test device for testing whether the automatic locking function of the control system still meets the requirements when the safety rope in the speed difference type fall arrester is pulled out quickly for many times. Background technique [0002] The speed differential fall arrester is a safety protection device specially designed for workers working at heights to prevent falls from heights. Its working principle is to use the speed difference of falling objects for self-control. The speed difference type fall arrester is mainly composed of a hook (ring), a housing, a locking mechanism, and a safety rope. During use, the hook (ring) at one end of the housing is buckled on the structure, and the hook or ring at one end of the safety rope is buckled in the safety buckle on the safety belt of the human body. During normal us...
