Detailed Description
The following describes embodiments of the present invention in further detail with reference to fig. 1 and 2.
A method for identifying the slag ladle position state in a slow cooling yard adopts a gantry crane 10 to transport slag ladles 20. After the gantry crane 10 moves to the target position, when the cart 11 and the trolley 12 are both in a stop state, the coordinates of the cart 11 and the trolley 12 are matched with the slag ladle position 21 in the slow cooling field,
if the matching fails, the current stop position of the trolley 12 on the portal crane 10 deviates from the slag ladle position 21, the transfer operation of the slag ladle 20 cannot be carried out, and the state change of the slag ladle position 21 caused by the transfer of the slag ladle 20 cannot occur, so that the trolley 12 is matched again when the trolley stops after the next displacement;
if the matching is successful, it is indicated that the current stop position of the trolley 12 on the gantry crane 10 is within the operation range of the slag ladle position 21, and the transfer operation of the slag ladle 20 can be performed, so that the slag ladle position 21 is marked as the current slag ladle position 21a, and then the state of the current slag ladle position 21a is updated according to the historical state of the current slag ladle position 21a and the operation condition of the lifting hook 13. Therefore, when the portal crane 10 carries out slag ladle transferring operation, the state change of the corresponding slag ladle position 21 is recorded in real time, so that the timely, accurate and synchronous state of the slag ladle position is ensured, and the safe and reliable completion of slow cooling operation is ensured.
According to the load condition on the lifting hook 13, the bag can be classified as no bag, empty bag or full bag. Because the material, the size and the shape of the slag ladle 20 are fixed, the weight of the slag ladle 20 loaded with slag and unloaded is relatively fixed, when the lifting hook 13 is unloaded, the state of the slag ladle is judged to be empty, when the load on the lifting hook 13 is consistent with the weight of the slag ladle 20, the slag ladle is judged to be empty, and when the load on the lifting hook 13 is consistent with the weight of the slag ladle 20 fully loaded with slag, the slag ladle is judged to be full.
The slag ladle position 21 includes four states: no-bag, empty-bag, air cooling and water cooling. When the slag ladle 20 is not placed in the slag ladle position 21, judging that the slag ladle is in a non-ladle state; when the slag ladle 20 placed in the slag ladle position 21 is empty, the state of the empty ladle is judged; when the slag ladle 20 is placed in the slag ladle position 21 and the slag ladle 20 is naturally and slowly cooled, the slag ladle is judged to be in an air cooling state; when the slag ladle 20 is placed in the slag ladle position 21 and the cooling water is sprayed to the slag ladle 20, the water cooling state is determined.
The historical state comprises the latest updated state of the slag ladle position 21, and the latest updated state of the slag ladle position 21 is defined as the latest historical state. The initial state of the slag ladle position 21 is no ladle.
In this embodiment, after the matching is successful, the lifting hook 13 is first guided to operate according to the current state of the slag ladle position 21a and the load condition of the lifting hook 13. That is, in step B11, if the current state of the slag ladle position 21a is not the no-ladle state and the state of the lifting hook 13 is empty ladle or full ladle, the maximum lowering position of the lifting hook 13 is defined. The safety accident caused by the contact between the hung slag ladle 20 and the slag ladle 20 positioned in the current slag ladle position 21a due to the descending of the lifting hook 13 hung with the slag ladle 20 is avoided.
And updating the state of the current slag ladle position 21a according to the historical state of the current slag ladle position 21a and the opening condition of the spray water ball valve. That is, in step B21, if the recent history state of the current slag ladle position 21a is air-cooled and the corresponding shower water ball valve is open, the state of the current slag ladle position 21a is updated to water-cooled. Furthermore, the slag ladle position 21 also comprises a slow cooling completion state. That is, the step B21 further includes updating the current slag ladle position 21a to be slowly cooled if the recent historical state of the current slag ladle position 21a is water-cooled and the corresponding shower water ball valve is closed.
Finally, the state of the current ladle position 21a is updated according to the load condition when the lifting hook 13 descends and ascends. The method specifically comprises the following steps of,
b31, recording the weight of the hook 13 and marking the descending state of the hook 13 when the hook 13 descends;
b32, recording the weight of the hook 13 and marking the lifting state of the hook 13 when the hook 13 is lifted;
b33, if the descending state of the lifting hook 13 is consistent with the ascending state, the state of the current slag ladle position 21a is unchanged;
if the descending state of the lifting hook 13 is no bag, and the ascending state is empty bag or full bag, the state of the current slag bag position 21a is updated to be no bag;
if the descending state of the lifting hook 13 is an empty ladle and the ascending state is a non-ladle state, updating the state of the current slag ladle position 21a to be an empty ladle;
if the descending state of the lifting hook 13 is full and the ascending state is no ladle, the state of the current slag ladle position 21a is updated to be air cooling;
if the descending state and the ascending state of the hook 13 are the other conditions, the current state of the hook 13 is calibrated.
Further, the state of the current slag ladle position 21a is judged according to the descending state of the lifting hook 13 and the current state obtained through calibration. That is, in step B33, if the descending state and ascending state of the hook 13 are the other states, the current state of the hook 13 is calibrated, and the routine proceeds to step B41:
if the descending state of the lifting hook 13 is full and the current state after calibration is no ladle, the state of the current slag ladle position 21a is updated to be air cooling;
if the descending state of the lifting hook 13 is full and the calibrated current state is full, the state of the current slag ladle position 21a is unchanged;
if the descending state of the lifting hook 13 is an empty bag and the calibrated current state is a no bag, updating the state of the current slag bag position 21a to be an empty bag;
if the descending state of the lifting hook 13 is an empty ladle and the calibrated current state is an empty ladle, the state of the current slag ladle position 21a is unchanged.
Furthermore, if the descending state of the hook 13 and the calibrated current state are the other conditions, the current state and the historical state of the hook 13 and the historical state of the current ladle position 21a are combined to manually determine the state of the current ladle position 21a. Here, the historical state includes the state update records of the hook 12 and the slag ladle position 21.
In other embodiments, after the coordinates of the cart 11 and the trolley 12 are successfully matched with the ladle position 21 in the slow cooling field, the step B11 may be omitted, and the process proceeds to the step B21 directly, or the steps B11 and B21 may be omitted, and the process proceeds to the step B31 directly.
In another embodiment, step B21 may be replaced by omitting step B21 and collecting information and updating the status of each ladle position 21 during the travel of gantry crane 10. The method specifically comprises the following steps:
in the running process of the gantry crane 10, a temperature measuring probe 30 installed on a cart 12 acquires infrared image information, acquires a temperature value of a slag ladle passing through a slag ladle position 21 by combining coordinate information of cart supporting legs 12, and updates the state of the slag ladle position 21 by combining the opening and closing conditions of the slag ladle position 21 corresponding to a spray water valve;
when the measured temperature value of the slag ladle in the slag ladle position 21 is lower than the water cooling set value, if the recent historical state of the slag ladle position 21 is that the corresponding spray water ball valve is in a closed state, the spray water ball valve of the slag ladle position 21 is opened and the state of the slag ladle position 21 is updated to be water cooling;
when the measured temperature value of the slag ladle in the slag ladle position 21 is lower than the slow cooling set value, if the recent historical state of the slag ladle position 21 is water cooling and the corresponding spray water ball valve is in an open state, the spray water ball valve of the slag ladle position 21 is closed and the state of the slag ladle position 21 is updated to be slow cooling completion.
In this embodiment, before identifying the slag ladle position state in the slow cooling pool, the cart 11, the trolley 12 and the hook 13 of the portal crane 10 are moved, coordinates of the cart 11 and the trolley 12 when the hook 13 is located at the central point of each slag ladle position 21 in the slow cooling pool are sequentially collected and marked, and a slag ladle position matching area 22 of each slag ladle position 21 is obtained according to the coordinates. In other embodiments, the ladle position matching area 22 of each ladle position 21 can also be marked artificially according to the arrangement of the slow cooling field.
