Embodiment Construction

[0026] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0027] Such as Figure 1 to Figure 5 As shown, it is a kind of anti-falling safety device 100 related to the present invention, which is applied in the vertical lifting system. The vertical lifting system is composed of a lifting mechanism 200, a traction mechanism 300 and a support mechanism 400. Both the mechanism 300 and the supporting mechanism 400 are existing structures, so no redundant description is given.

[0028] The anti-falling safety device 100 includes a fixing seat 1, a clamping seat 2 and a first engaging part 3, the lower end of the fixing base 1 is fixed on the lifting mechanism 200, and the upper end of the clamping seat 2 is connected with the traction mechanism 300. An engaging portion 3 is disposed on the support mechanism 400 and extends along the extending direction of the guide rail 41...

Abstract

The invention discloses an anti-falling safety device, which includes a fixed seat with a lower end fixed on a lifting mechanism, a clip connection seat with an upper end connected with a traction mechanism, and a first engagement part arranged on a support mechanism and extending along the guide rail extension direction. The middle part of the clip connection seat can be rotarily connected on the fixed seat via a rotary shaft, between the upper end of the clip connection seat and the fixed seat is also arranged an elastic body for driving the upper end of the clip connection seat to move close to the fixed seat, and at the lower end of the clip connection seat is also formed a second engagement part capable of being clip-connected to the first engagement part. According to the invention, when an accident occurs to lose a traction force, the second engagement part at the lower end of the clip connection seat can quickly get clip-connected to the first engagement part on the support mechanism, so that the whole lifting mechanism is locked on the support mechanism, to therefore prevent falling of the lifting mechanism; and the lifting mechanism can be quickly locked no matter whether a transmission chain is normal, so as to greatly reduce potential safety hazards of the whole vertical lifting system.

Description

technical field [0001] The invention relates to a fall prevention safety device of a vertical lifting system, which can automatically lock the lifting mechanism to prevent the lifting mechanism from falling when the traction mechanism fails. Background technique [0002] In the machinery industry, the vertical lifting system is widely used. In some extreme cases, the failure of the traction mechanism may cause the accident of the lifting mechanism falling. Especially in the case of heavy load, how to prevent the lifting mechanism from accidentally falling is particularly important. [0003] The vertical lifting system is generally composed of a traction mechanism, a support mechanism and a lifting mechanism. A guide rail is formed on the support mechanism. The lifting mechanism can be slidably arranged on the guide rail and can only move up and down. The pulling force of the lifting mechanism. At present, the common protective devices to prevent the accidental fall of the li...
