after the material is taken from the cargo carrying platform, in order to ensure that the lifting mechanism can drive the cargo carrying platform after the material is taken to move, the lifting mechanism drives the cargo carrying platform to ascend by a preset height, wherein the preset height can be 10mm, the weight which can be born by the lifting mechanism is avoided to exceed after the material is taken from the cargo carrying platform, the cargo carrying platform does not fall down because the upright post is locked by the braking jaw to prevent the cargo carrying platform from falling down, and if the lifting mechanism is not controlled to drive the cargo carrying platform to ascend for verification, the locking of the braking jaw to the upright post is directly released, the falling risk of the cargo carrying platform is possible.
S400, controlling the lifting driving assembly to drive the telescopic piece to release the connection with the connecting arm and reset.
The lifting driving assembly drives the sliding part to descend so that the telescopic part descends together, the telescopic part is separated from the connecting arm under the guidance of the guiding part, the connecting arm falls under the action of gravity, and the braking jaw is driven to be away from the upright post, so that locking of the upright post is relieved, and the lifting mechanism can normally drive the cargo carrying platform to ascend and descend.
When the lifting mechanism drives the cargo carrying platform to move to the material taking station, the lifting driving assembly drives the telescopic piece to ascend, and in the ascending process of the telescopic piece, the guide piece guides the telescopic piece to move towards the direction close to the connecting arm and is connected with the connecting arm, and the lifting driving assembly continues to drive the telescopic piece to ascend, so that the connecting arm drives the brake jaw to lock the upright post, and further the cargo carrying platform is prevented from falling in the material taking process; even if the wire rope driving the cargo carrying platform to lift breaks, the brake jaw prevents the cargo carrying platform from falling down, so that the safety accident caused by the process that the cargo carrying platform falls to completely stop is avoided; when the cargo carrying platform finishes taking the material, the lifting device drives the cargo carrying platform to ascend for a preset distance, so that the weight of the cargo carrying platform which finishes taking the material is still within the lifting capacity range of the lifting device, and the phenomenon that the cargo carrying platform falls down due to the fact that the lifting device cannot bear the weight of the cargo carrying platform due to the fact that the brake jaw is removed first is avoided; after the lifting device drives the cargo carrying platform to ascend for a preset distance, the lifting driving piece drives the telescopic piece to descend, the connecting arm descends together, the braking jaw is separated from the upright post, and the telescopic piece is separated from the connecting arm under the guidance of the guiding piece in the descending process and finally resets.
In addition, the invention also provides a computer readable storage medium, wherein the computer readable storage medium stores a stacker control program, and the stacker control program realizes the steps of the stacker control method when being executed by a processor.
The foregoing is only the preferred embodiments of the present invention, and not the limitation of the scope of the present invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the present invention.
