An anti-fall elevator holding mechanism

Abstract

The invention discloses an anti-falling elevator tight holding mechanism. The anti-falling elevator tight holding mechanism is characterized in that a warping plate is arranged at the lower portion of a movable clamp block, and hinge shafts are arranged on the front side and the rear side of the middle portion of the warping plate correspondingly and fall into a vertical guiding groove in the shell; the positions of the hinge shafts in the guiding groove are higher than the inner end position of the warping plate; the distance between each hinge shaft and a guide rail is smaller than the length between each hinge shaft and the right end of the warping plate; the left side of the warping plate is naturally warped, and the distance is kept between the right end of the warping plate and the guide rail; and the upper portion of the shell is connected with a draught fan, a draught fan impeller shaft is connected with a walking wheel through a swinging arm, a driven belt wheel and a following belt wheel are in drive connection through a belt, the power of the walking wheel is transmitted to the draught fan, an overturning plate is controlled to overturn, and a round ball falls down to start braking. The anti-falling elevator tight holding mechanism is stable in work structure and low in failure probability.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to a fall-preventing elevator holding mechanism. Background technique [0002] With the vigorous advancement of urbanization in our country, urban construction is changing with each passing day, and there are many high-rise buildings. Elevators are a must in high-rise buildings. The number of elevators is increasing year by year. With the increase of service life, safety problems caused by elevator failures are often reported in the newspapers. The safety tongs can block the guide rail to realize the emergency braking of the car when falling down the ladder, but the existing safety tongs driving structure fails frequently, and these problems still need to be solved technically. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fall prevention elevator gripping mechanism. [0004] The technical solution adopted by the present inventi...
