Problems solved by technology

[0002] The opening and unloading process of the grab bucket in bulk cargo operation is as follows: when the support rope and the opening and closing rope drop to the range of 3 meters from the cargo pile, they stop at the same time, and then the support rope remains motionless, and the opening and closing rope descends to realize the opening and unloading until the grab Stop after the bucket is fully opened; so far, the unloading process is completely dependent on the manual operation of the staff; automatic unloading of the grab bucket cannot be realized
[0003] In order to solve the above problems, the existing patent notification number CN207312962U discloses an automatic unloading system, but this device is too rigid when grasping, and cannot detect the grasping weight, and some materials have the same volume density. , so that the weight difference during a single grab is large, which will lead to potential safety hazards in grabbing

Embodiment 1

[0017] see Figure 1~3 , in an embodiment of the present invention, a grab bucket automatic unloading system for a portal crane includes a controller, a distance measuring module, a supporting machine control motor, an opening and closing machine control motor, and a human-computer interaction module. The distance measuring module is set at On the beam of the gantry crane, including the cargo pile distance detection module and the grab distance detection module, the distance measurement module, the support machine control motor, the opening and closing machine control motor and the human-computer interaction module are all connected to the controller, and the controller is supported through the control The machine controls the motor to drive the movement of the support rope, and the controller controls the motor to drive the movement of the opening and closing rope by controlling the opening and closing machine. The human-computer interaction module includes a working mode sele...

Embodiment 2

[0027] The difference from Embodiment 1 is that the controller is also electrically connected with an infrared sensor and a voice prompt module. When someone is detected around the infrared sensor, the controller will control the voice prompt module to work, thereby sending a leave signal to the surrounding people , further improving the security of the device.

Abstract

The invention discloses an automatic portal crane grab unloading system which comprises a controller and a ranging module, and is characterized in that the ranging module, a support machine control motor, an on-off machine control motor and a man-machine interaction module are connected to the controller; the controller controls the support machine control motor to drive a holding rope to move; the controller controls the on-off machine control motor to drive an on-off rope to move; the controller is further electrically connected to a safety detection module. According to the arrangement of the safety detection module, the safety detection module comprises a holding force detection module, a single load detection module and a steering speed detection module, the problem that working partsare damaged by the grab is solved, overloading is avoided, and the condition that the device has potential safety hazards due to high centrifugal force generated by rotation is avoided. Due to the arrangement of the safety detection module, the grabbing safety of the grab is greatly ensured.

Description

technical field [0001] The invention relates to the technical field of portal crane unloading, in particular to an automatic grab bucket unloading system of a portal crane. Background technique [0002] The opening and unloading process of the grab bucket in bulk cargo operation is as follows: when the support rope and the opening and closing rope drop to the range of 3 meters from the cargo pile, they stop at the same time, and then the support rope remains motionless, and the opening and closing rope descends to realize the opening and unloading until the grab After the bucket is fully opened, it stops; so far, the unloading process is completely dependent on the manual operation of the staff; automatic unloading of the grab bucket cannot be realized. [0003] In order to solve the above problems, the existing patent notification number CN207312962U discloses an automatic unloading system, but this device is too rigid when grasping, and cannot detect the grasping weight, a...
