Embodiment Construction

[0040] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0041] refer to figure 1 , a safety mechanism for anti-falling, comprising a body of the anti-falling device and a connecting mechanism. The fall arrester body is connected to the use equipment and the ground foundation or the base of the use equipment through the connection mechanism. The connecting mechanism includes two connecting parts, namely an upper connecting part 1 and a lower connecting part 4 . Wherein, the upper connecting part 1 is arranged on the upper end of the outer sleeve 6, and the lower connecting part 4 is arranged on the lower end of the inner sleeve 7, and the upper end of the outer sleeve 6 is connected with the equipment using the present invention through the upper connecting part 1, and the lower connecting part 4. Connect ...

Abstract

The invention relates to the field of mechanical safety protection, in particular to an anti-falling safety mechanism. The anti-falling safety mechanism comprises an anti-falling device body and a connecting mechanism, wherein the anti-falling device body is connected with the connecting mechanism, the connecting mechanism is connected with an external fixing base, the anti-falling device body comprises a ball screw, the ball screw is fixed in an outer sleeve, the outer sleeve is arranged outside the inner sleeve in a sleeve mode, a ball nut is arranged on the inner sleeve, the ball nut is screwed into the ball screw, and the ball nut is provided with a mechanical braking device for braking rotary action of the ball nut after providing static friction force. Due to adoption of the technical scheme, the mechanism is applied to occasions with potential falling hidden danger of equipment machinery, and can play an effective buffering role when the mechanical equipment generates huge gravitational acceleration due to faults, so that the protection on mechanical parts is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical safety protection, in particular to an anti-drop safety mechanism. Background technique [0002] At present, most of the anti-fall safety structures used in the fields of elevators and construction hoists use gear cone drum type anti-fall safety devices, which are composed of gears, centrifugal speed limiting devices and cone-shaped brakes. The principle is: when the protection target goes down When the running speed reaches the calibrated operating speed, the throwing block of the centrifugal speed limiting device drives the cone drum to move towards the brake band and contact it to generate a braking torque, so that the gear stops rotating and avoids damage to the equipment due to a large impact force. Cause safety accidents, so as to achieve the purpose of falling prevention. [0003] However, when the traditional structure is working, the gravity of the protection target all acts on the ge...
