Anti-glide safety device

Abstract

The invention relates to the field of mechanical equipment safety protection, in particular to an anti-glide safety device. The anti-glide safety device aims at solving the problem that after a vertical lifting device is powered off or a lifting mechanism loses efficiency, the reliability is poor when a lifted object falls to generate risks. The anti-glide safety device is characterized by comprising an anti-glide lock hook, an anti-glide lock hook seat plate, a linkage rod, a traction electromagnet, a linkage rod pin shaft, a lock hook pin shaft and a protection cover. The anti-glide lock hook is movably connected with the anti-glide lock hook seat plate; one end of the linkage rod is movably connected with the inner side of the anti-glide lock hook, and the other end of the linkage rod is movably connected with the traction electromagnet through the linkage rod pin shaft; the traction electromagnet is fixedly connected with an inclined plate on the anti-glide lock hook seat plate; and the anti-glide lock hook seat plate is covered with the protection cover. According to the anti-glide safety device, the anti-glide lock hook is reliably clamped into a wedge block or a lock hole under the effect of self weight of the lifted object, the anti-glide lock hook can be naturally in the locking state after power is off, the bearing capacity is high, and the anti-glide safety device has the beneficial effects of being simple in structure, convenient to operate and wide in application scope.

Description

technical field [0001] The invention relates to the field of mechanical equipment safety protection, in particular to an anti-sliding safety device. Background technique [0002] Large-scale vertical lifting equipment is widely used in various links of industrial production, such as large-scale lifting doors, large-scale gantry lifts, lifting gate valves, lifting winches, etc. Or the power of the downward movement, mostly using electric power, pneumatic or hydraulic pressure as the power source. When the power source fails due to power failure or other faults, the lifting object will slide down due to its own weight, causing irreparable losses. Because the large vertical lifting equipment has a large weight of the lifting object, and the free sliding of the lifting object has great destructive power, it is necessary to use large vertical lifting equipment. The lifting equipment is equipped with an anti-slip safety device to avoid falling and sliding after the lifting mechan...
