Anti-collision device for cart traveling mechanisms of ship unloader and control method

Abstract

The invention relates to an anti-collision device for cart traveling mechanisms of a ship unloader and a control method. The anti-collision device for the cart traveling mechanisms of the ship unloader comprises a distance measuring module, an image module and a main controller. The distance measuring module comprises a distance displayer and a plurality of distance measuring sensors; the distance displayer is installed in a cab, and the distance measuring sensors are installed on the front sides and the rear sides of all the cart travelling mechanisms; the image module comprises an image displayer and a plurality of image sensors, the image displayer is installed in the cab, and the image sensors are installed on the front side and the rear side of all the cart travelling mechanisms; and the main controller is in communication connection with the distance displayer, the distance measuring sensors, the image displayer and the image sensors. Compared with the prior art, the real-time distance between the cart travelling mechanisms and the obstacle is obtained through the distance measuring module, real-time images of the cart travelling mechanisms are obtained through the image sensors, and a visual blind area is eliminated, so that collision prevention is achieved, and the digitization and visualization degree is higher; and hidden dangers of poor contact and a short circuit of an existing limiting column-travel switch structure are eliminated.

Description

technical field [0001] The invention relates to the technical field of ship unloaders, in particular to an anti-collision device and a control method for a traveling mechanism of a cart of a ship unloader. Background technique [0002] The ship unloader is equipment for unloading ships at ports, docks, and shores. A ship unloader cart is equipped with 4 cart traveling mechanisms. When the ship unloader is running, the movement of the cart traveling mechanisms along the track drives the unloading Cart movement. During the horizontal movement of the ship unloader cart on the rail, in order to avoid colliding with the ends of both sides of the rail or colliding with objects intruding into the movement range of the cart device or detaching from the side end of the rail, such as figure 2 As shown, limit switches (travel switches) are often used at the ends of both sides of the rail to limit the range of motion of the traveling mechanism of the cart. The travel switch is connect...

Problems solved by technology

That is: it can prevent the movement of the cart beyond the limit, but the anti-collision function is not perfect

[0006] 3. If figure 2 As shown, within a range of more than ten meters between the A2 side and the B1 side of the traveling mechanism of the cart, there is no protection for people and objects near the track.

However, the driver has a blind spot when working at a high place, and there is a risk of collision with the surrounding area during the movement of the cart mechanism, which poses a great threat to safe production
