Anti-falling device for perpendicular counterweight

Abstract

The invention discloses an anti-falling device for a perpendicular counterweight. The anti-falling device comprises two supporting structures which are oppositely arranged, wherein a fixed framework is connected on the supporting structures; two connecting shafts which are oppositely arranged are mounted on the fixed framework; the two ends of each connecting shaft connected to hook bodies throughtorsion springs; adjacent hook bodies on different connecting shafts are connected through a first connecting line; the two first connecting lines are connected by two second connecting lines; the second connecting lines are provided with an annular part in a penetrating mode; the two ends of the annular part separately are provided with third connecting lines in the penetrating mode; and one ends of the two third connecting lines are connected to speed difference anti-falling devices. The anti-falling device accomplishes locking of the counterweight while the counterweight has an accident, and has a higher success rate, so that the risk that lower floor is destroyed is avoided; a bored position above a conveyor counterweight device is utilized for mounting the anti-falling device; load on mounted floor is small in a working process, so that the anti-falling device is suitable for being additionally arranged on an existing model; and counterweight can be effectively prevented from laterally swinging to hit against a floor wall body.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a vertical heavy hammer anti-falling device. Background technique [0002] The tensioning device is an essential part to ensure the normal operation of the belt conveyor, and the middle weight hammer type tensioning device is the most widely used tensioning device with simple structure. The most basic feature is that the tensioning force is provided by the gravity of the weight box, and the weight of the weight box ranges from 2-3 tons to more than ten tons. The suspension height is generally several meters high, or even more than ten meters high. Due to the high-load operation of the tape machine and some unexpected factors, such as metal objects blocking the tape, the tape will suddenly break. If the heavy hammer is arranged indoors, it will fall directly. Impacting the floor or foundation is very likely to cause the floor to collapse and threaten the safety of on-site personnel, caus...

AI Technical Summary

Problems solved by technology

This form of fracture will cause the weight to tilt when the tape is broken, which will cause the weight to swing left and right, breaking the left and right walls or frames, which will easily lead to accidents.
