Safety early warning method and equipment for hoisting machinery

Abstract

The invention relates to the technical field of hoisting machines, and discloses a hoisting machinery safety early warning method and equipment, the hoisting machinery safety early warning equipment comprises a hoisting arm, a hoisting rope and a hook, an outer sleeve is fixedly arranged at the bottom of the hoisting arm, two arc-shaped plates are symmetrically arranged in the outer sleeve, the hoisting rope penetrates through the space between the two arc-shaped plates, and connecting rods are fixedly arranged on the sides, away from each other, of the two arc-shaped plates; first cavities are formed in the two sides of the outer sleeve correspondingly, extrusion blocks are arranged in the two first cavities correspondingly, first springs are fixedly arranged on the side walls of the extrusion blocks, the other ends of the first springs are fixedly connected with the side walls of the first cavities correspondingly, touch sensors are fixedly arranged on the tops of the two first cavities correspondingly, and the extrusion blocks can make contact with the touch sensors. The ends, away from the arc-shaped plate, of the two connecting rods penetrate into the two first cavities correspondingly and are fixedly connected with the side walls of the two extrusion blocks correspondingly. According to the safety early warning method and equipment for the hoisting machinery, the shaking amplitude of the hoisting rope can be limited, and the danger of hoisting an object is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting machines, in particular to a hoisting machine safety early warning method and equipment. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, aerial crane, and crane. Even for light and small lifting equipment, the lifting weight can reach the tonnage. When an accident occurs, it may cause damage to items and casualties. Sometimes, when the heavy object shakes, it is easy to affect the work of the electric hoist. Once the heavy object falls, it will be thrown out in the form of a parabola due to inertia, which will pose a great safety hazard and cause damage to the hoisted object. Dangerous if shaken or dropped. [0003] Among them, the patent number is CN107738987A, which discloses a two-state safety auxiliary device for the lifting arm of light and small li...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a lifting machinery safety early warning method and equipment, which can control the swaying range of the sling, reduce the danger of hoisting objects, and solve the problem that there is no function to reduce the swaying range of objects at present. Make shaking objects still have certain dangerous problems
