The operation method of the bridge ship unloader mainly comprises cabin opening operation, cabin expansion operation and cabin cleaning operation, and is shown in figure 1.
Step S1: and (5) opening the cabin.
S11: the hold is divided into odd and even holds from bow to stern.
The number of cabins of a ship is typically odd. The ship is assumed to have nine cabins, and the directions from the bow to the stern are as follows: odd, even, odd, even, and odd compartments, as shown in fig. 4. The hatch of the cabin is generally located in the center of the cabin roof, and the grab bucket enters from the hatch and grabs the material below the hatch.
S12: and controlling the grab bucket to grab the even numbered cabins, and after grabbing the materials with the set weight, grabbing the odd numbered cabins to grab the materials with the set weight.
The number of grab buckets of the ship unloader is larger than the number of even numbered cabins and the number of odd numbered cabins, so that the grab operation on the even numbered cabins or the odd numbered cabins is ensured simultaneously.
The control grab bucket grabs the material in the even number cabin first, and after every even number cabin is grabbed the material of settlement weight, running gear removes, drives the grab bucket and removes near odd number cabin, and the control grab bucket snatchs the material in the odd number cabin again, and every odd number cabin is grabbed the material of settlement weight.
When the grab bucket snatchs the operation, mainly snatch the material in the hatch below scope. On the premise of ensuring the safe distance between the grab bucket and the cabin, the grabbing range is expanded as much as possible. The gripping range of the hopper is generally the range below the hatch.
S2: and (5) carrying out cabin expansion operation.
Because the grab bucket is near the odd-numbered cabin when the cabin opening operation is finished, the odd-numbered cabin is expanded first and then the even-numbered cabin is expanded when the cabin is expanded, so that frequent cabin position exchange is avoided. And (4) cabin expansion, namely cleaning the selected cabin expansion position by using a grab bucket. The material supply operation is that the loader 6 conveys the materials at other positions of the cabin to the grabbing range of the hopper (generally, the position below the hatch).
S21: and selecting the cabin expansion position of the odd-numbered cabin, expanding the selected cabin expansion position, hoisting the expanded cabin position into a loader after the cabin expansion is finished, feeding by the loader, and conveying the materials in other areas in the odd-numbered cabin to the hopper grabbing range.
In this step, the cabin expansion position of the odd number of cabins is selected, and the cabin expansion is performed on the selected cabin expansion position, which specifically includes: and selecting the bilge position corresponding to the hatchway opening of the odd number of cabins as a cabin expanding position, and expanding the cabin at the cabin expanding position by using the grab bucket. The hatch is positioned at the center of the top of the cabin, so that the cabin expanding position of the odd-numbered cabin is positioned in the middle of the cabin, the stability of the whole ship can be ensured, and the completion of cabin cleaning of the even-numbered cabin can be insisted.
S22: and selecting the cabin expansion position of the even-numbered cabin during the feeding period of the loader in the odd-numbered cabin, expanding the cabin at the selected cabin expansion position, hoisting the expanded cabin at the cabin expansion position into the loader after the cabin expansion is finished, feeding by the loader, and conveying materials in other areas in the even-numbered cabin to the hopper grabbing range.
In this step, the cabin expansion position of the even number of cabins is selected, and the cabin expansion is performed on the selected cabin expansion position, which specifically includes: and selecting the front half part (close to the bow) of the bilge of the even number of the cabins or the rear half part (close to the stern) of the bilge as a cabin expanding position, and expanding the cabin at the cabin expanding position by using a grab bucket. That is to say, the cabin expanding position of the even-numbered cabin is the front half part or the rear half part, so that the materials in the even-numbered cabin can be discharged as soon as possible.
During the expansion of the even numbered compartments, the loaders in the odd numbered compartments perform the feeding operation. And at the end of the cabin expansion of the even numbered cabins, the loading machines in the odd numbered cabins finish the feeding operation.
S3: and (5) clearing the cabin.
When the cabin expanding operation of the even-numbered cabin is finished, the loader in the odd-numbered cabin finishes the feeding operation, so that the grab bucket moves to the position near the odd-numbered cabin, and the grabbing operation is firstly carried out on the odd-numbered cabin until the material cannot be grabbed; then, grabbing operation is carried out on the even number of cabins until the materials cannot be grabbed; then carrying out grabbing operation on the odd cabins; and circulating in sequence until the materials in the cabin are completely discharged.
Therefore, when the cabin is cleaned, the grab bucket is controlled to alternately grab the odd numbered cabins and grab the even numbered cabins; when grabbing operation is carried out on the odd numbered cabins, the loader in the even numbered cabins carries out feeding operation; when grabbing operation is carried out on the even numbered cabins, the loader in the odd numbered cabins carries out feeding operation so as to improve operation efficiency.
In the embodiment, during the cabin cleaning operation, when the odd-numbered cabin is subjected to grabbing operation, the loader in the odd-numbered cabin stops at a position close to the sea and far away from the grabbing range of the grab bucket in the cabin; after the grabbing is finished, the loader performs feeding operation again; so as to avoid the cross operation of the grab bucket and the loader and ensure the safety of the loader.
In this embodiment, during the cabin cleaning operation, when the even-numbered cabin is subjected to the grabbing operation, the loader and the grab bucket in the even-numbered cabin perform the partitioned feeding operation, that is, the mode of feeding and grabbing is adopted simultaneously, so as to increase the cabin cleaning speed of the even-numbered cabin. But the loader and the grab bucket work in a partitioning mode, and cross operation is strictly forbidden to ensure safety.
As another preferred design scheme of this embodiment, during the cabin cleaning operation, when the even number of cabins are grabbed, the grab bucket grabbing range is divided into a sea side grabbing range and a land side grabbing range, the sea side grabbing range is grabbed first, and after the grabbing is finished, the land side grabbing range is grabbed; during grabbing operation on the sea side grabbing range, the loaders in even numbered cabins perform intermittent feeding operation after the grab bucket leaves the hatch opening position, and the moving area of the loaders avoids the sea side grabbing range, so that cross operation is avoided, and cabin cleaning efficiency is guaranteed; during grabbing operation on the land side grabbing range, the loaders in the even numbered cabins continuously feed in the sea side grabbing range, and the moving areas of the loaders avoid the land side grabbing range, so that cross operation is avoided, and cabin cleaning efficiency is guaranteed.
As another preferable configuration of this embodiment, when the even-numbered compartments are subjected to the grabbing operation during the cabin cleaning operation, the loader in the even-numbered compartments is subjected to the feeding operation after the grab bucket leaves above the hatch. When only the materials on the side of the land side cabin are left in the even number of cabins, the partitioned operation of the grab bucket and the loader cannot be realized in space, and at the moment, when continuous operation is needed for key ships or key cabins, the operation of the grab bucket and the loader needs to be staggered in time, so that the loader performs feeding operation (including material taking operation and material dumping operation) after the grab bucket leaves the position above the hatch.
When the grab bucket passes in and out of the hatch of the cabin, the distance between the grab bucket and the hatch edge is obtained, if the distance is smaller than the set distance, an alarm is given to remind a driver, the position of the grab bucket is corrected, and the grab bucket and the hatch are prevented from colliding so as to ensure the safety of the grab bucket and the cabin.
In the embodiment, a laser scanner is installed at the bottom of a cab, and a controller, an alarm and a display screen are installed in the cab; laser scanner scans the image information of hatch department to send to the controller, the controller is handled received image information, obtains the distance between hatch edge and the grab bucket, when this distance is less than the settlement distance, the control alarm reports to the police to remind the driver, in time correct the grab bucket position, prevent grab bucket and hatch collision. Meanwhile, the controller processes the received image information and sends the image information to the display screen for display, and the display screen displays the image information at the hatch so as to be convenient for a driver to observe.
