Description

Crane controllable volume alarm device based on video identification

Technical Field

The utility model relates to the technical field of crane alarm, in particular to a crane controllable volume alarm device based on video identification.

Background

The existing gantry crane with a frame structure is characterized in that a travelling mechanism of the gantry crane is called a 'cart', and the gantry crane consists of two sets of 'door legs' and a pair of bearing rail beams arranged on the door legs; the trolley frame is erected on the rail bearing beam, the cab is suspended below the trolley frame, the cab faces the front door leg, and the cab can walk back and forth along the rail bearing beam during operation; wheels are arranged on the door legs, and the door can walk left and right on the ground along the direction vertical to the rail bearing beam during operation. Limited by the structural shielding of the gantry crane, the left side and the right side of the cart are positioned in sight blind areas of a crane driver, the cart possibly generates accidents that the traveling part collides with ground obstacles in the ground traveling process, and common obstacles comprise trucks, pedestrians or traffic isolation facilities which invade the safety limit of the traveling part of the cart, so that equipment is damaged, and casualties can be caused when serious.

In order to cope with various collision accidents, a set of audible and visual alarms and cameras are respectively arranged at the front end positions of four door legs of a cart of a general portal crane, a video recording device (such as a digital video recorder) is arranged in an electrical room, continuous audible and visual alarm reminding is carried out in the traveling process of the cart, continuous shooting and video recording are carried out on the front of the traveling of the cart, and video recording evidence of the accident is obtained by adopting a manual query mode when the collision accident happens, so that the main stream anti-collision system has the following defects in practical application:
