Safety positioning early warning device for bridge crane

Abstract

A safety positioning early warning device for a bridge crane comprises a mounting support, a positioning mechanism, an early warning mechanism and a controller, the positioning mechanism, the early warning mechanism and the controller are connected with the mounting support, the mounting support is connected with a traveling mechanism of the bridge crane, the positioning mechanism is mounted on one side of the mounting support, and the early warning mechanism is mounted on the other side of the mounting support. And the early warning mechanism and the controller are mounted on the other side of the mounting bracket. Whether the crane is unloaded at present is judged through a visual detection function of the industrial camera, a sound and light dual safety warning mode is carried out in a non-unloaded lifting state, and nearby ground personnel are reminded by utilizing visual and auditory effects; the safety positioning and early warning device synchronously displaces along with the movement of the vehicle mechanism, and the actual contour of the hoisted cargo projected to the ground by the laser projector moves along with the movement, so that the safety positioning and early warning device dynamically displays the falling risk area of the hoisted cargo in real time; the safety positioning and early warning device is connected with a power supply device of the crane, so that an integrated power supply mode of the safety positioning and early warning device and the crane is realized.

Description

technical field [0001] The invention relates to the technical field of crane safety, in particular to a safety positioning early warning device for bridge cranes. Background technique [0002] Bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting, also known as the overhead crane. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides, and the hoisting trolley runs horizontally along the rails laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame for hoisting and transporting materials. Hindered by ground equipment. This kind of crane is widely used in indoor and outdoor warehouses, factories, docks and open storage yards. [0003] Cranes are widely used, large in number, large in parameters, harsh in operating environment, and numerous in operators, and accidents occur frequen...

AI Technical Summary

Problems solved by technology

In the process of lifting objects by bridge cranes, improper operation, broken slings, brittle hooks and other conditions often cause the objects to be lifted to fall.

The personnel on the ground do not know that the crane is performing lifting operations or know that there are lifting operations above, but because they have no anticipation and awareness of prevention of accidental falling objects, coupled with the high noise in the working area and the inevitable need for cross operations, etc. Factors, the ground personnel do not have an intuitive reminder of the location of the dropped objects, so safety accidents are prone to occur during the lifting operation, resulting in casualties

Some of the traditional cranes currently in use are equipped with early warning and prompting devices, but the early warning and prompting devices cannot move synchronously with the horizontal displacement of the hoisted goods, resulting in the failure of the positioning and early warning, and cannot accurately project the actual outline of the hoisted goods, resulting in early warning and prompt errors. Crane operating safety is poor

In addition, the traditional crane safety warning device needs to replace the battery, which is extremely inconvenient and has potential safety hazards
