Problems solved by technology

[0005] The purpose of the present invention is to provide a windage induction type fall arrester which is different from the triggering principle of the existing fall arrester. When the elevator slides down rapidly, a large windage is generated and the work of the windage trigger mechanism is used. The windage induction type fall arrester can solve the problem of weightlessness The one-way problem of induction, and can solve the stability problem of electronic induction equipment

Embodiment Construction

[0037] The anti-fall device of the present invention adopts the principle of wind resistance for induction, and the moving object can adapt to the downward movement, upward movement or tilting movement, and solves the unidirectional problem of the existing weightlessness induction, and because the mechanical structure adopted by the present invention is more stable, relatively It is more reliable than electronic sensing equipment.

[0038] like figure 1 , 6 As shown, the elevator fall arrester includes a housing 200 fixedly connected to the elevator car. The housing 200 is provided with a guide rail guide groove 210 matching the guide rail 100. The housing 200 is also connected with a wind resistance sensing mechanism 300. A linkage mechanism 400 matching with the windage sensing mechanism 300 is installed on the body 200 , and a brake slider 500 connected with the linkage mechanism 400 and used for braking is slidably matched with the casing 200 .

Abstract

The invention discloses a wind resistance induction type fall arrester for elevator safety braking. The wind resistance induction type fall arrester comprises a shell fixedly connected to an elevatorcar, and the shell is provided with a guide rail slot matched with a guide rail; the shell is further connected to a speed sensing mechanism, and provided with a link mechanism matched with the speedsensing mechanism; the shell is further matched with braking sliding blocks connected to the link mechanism and used for braking; the speed sensing mechanism is used for sensing the elevator moving speed, and connected to the link mechanism, and the link mechanism comprises a rotary table; a shift lever is connected to the rotary table, and a rotating shaft can be driven to rotate synchronously through the rotation of the shift lever; the rotary table is installed on the shell, and can be rotated around its own axis; the rotary table is hinged to a pair of connecting rods separately, and connecting lines of the hinged positions between the connecting rods and the rotary table penetrate the central axis of the rotary table, and are arranged on the both sides of the rotary table symmetrically; and the suspension ends of the connecting rods are hinged to the braking sliding blocks.

Description

[0001] This invention is a divisional application of the invention patent with the application date of February 05, 2017, the application number: 2017100647301, and the invention title of "wind resistance sensing device based on aerodynamics". technical field [0002] The invention relates to a wind resistance sensing device. Background technique [0003] At present, known elevator fall arresters are mainly triggered in two ways. One is to use weightlessness to sense, and when the elevator slides rapidly, the counterweight is in a state of weightlessness to trigger; Sensing, such as velocity sensing. [0004] The invention provides an elevator fall arrester triggered by wind resistance, which is different from the trigger principle of the existing fall arrester. Contents of the invention [0005] The purpose of the present invention is to provide a windage induction type fall arrester which is different from the triggering principle of the existing fall arrester. When the...
