Problems solved by technology

[0004] 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

[0031] 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.

[0032] Such as 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 wind resistance induction equipment based on air flow mechanics. The wind resistance induction equipment comprises a fan housing and a shifting lever, wherein the shifting lever is connected with the wall of the fan housing. The fan housing is a bowel body with a vertically-downward opening, a center sleeve is further arranged in the fan housing and connected with the wall of the fan housing through a connecting plate, and air passages communicating with an inner cavity of the fan housing are formed between the center sleeve and the wall of the fan housing in a spaced mode. An air passage switch is arranged in the center sleeve in a matched mode and comprises a guiding shaft sleeved with the center sleeve and coaxially arranged with the center sleeve, an inner air plate is installed on the end side, located inside the fan housing, of the guiding shaft, and a limiting ring is installed at the top end of the guiding shaft. The guiding shaft is further sleeved with a restoration spring between the fan housing and the inner air plate, and the restoration spring pushes the inner air plate to move towards the inner cavity direction of the fan housing. According to the wind resistance induction equipment based on the air flow mechanics, wind resistance generated in the movement process of an object is used for controlling, the larger the speed of object movement is, and the larger the generated wind resistance is; and therefore, triggering is conducted through the wind resistance induction equipment, and rapid induction during speeding is achieved.

Description

technical field [0001] The invention relates to a wind resistance sensing device. Background technique [0002] 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. [0003] 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 [0004] 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 can solve the st...
