Description

Technical Field

[0001] The invention relates to the technical field of coke drum transverse movement and traction, and in particular to an improved method for a dry coke quenching coke drum transverse movement and traction device. Background Art

[0002] In some steel joint ventures, after decades of development, the scale has become larger and larger, and the production equipment and facilities are updated and eliminated faster and faster. In order to ensure the stability of the production chain, advanced equipment and facilities need to be built and put into production in advance before the old equipment and facilities are eliminated. Due to limited land resources, during the period when the new equipment and facilities are planned and the old equipment and facilities coexist, it is inevitable to make some adjustments to the layout of the new equipment and facilities.

[0003] Take a steel plant as an example. Since the 5-meter coke oven in the south area is still in production, the No. 9 and No. 10 coke ovens can only be built in the north area as replacement coke ovens. However, land resources in the north area are still scarce, and the supporting dry coke quenching hoist derrick cannot be built above the coke quenching car track, but can only be built on the side of the coke quenching car track. For this reason, the manufacturer designed a coke tank transverse traction device. Due to the increase in equipment, a new interlocking logic needs to be designed to ensure the safe and efficient operation of the process of sending full coke tanks and receiving empty coke tanks. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides an improved method for a lateral movement and traction device of a coke dry quenching tank, which solves the problems existing in the prior art.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an improved method for a CDQ coke tank transverse traction device, characterized in that: the specific operations are as follows:

[0008] The improvements are as follows:

[0009] Move the coke tank horizontally to the bottom of the lifting derrick without the "coke tank stop signal 2" signal;

[0010] Adjust the position of the ejector limit signal detection piece at the bottom of the coke tank trolley and lift it up 2mm in the vertical direction to ensure that the traction hook is evenly stressed and can be lifted into place smoothly;

[0011] Install a gasket on the head track of the transverse traction device to ensure that it is consistent with the flatness of the traction track;

[0012] The traction hook at the head of the transverse traction device was rectified by grinding it and reducing its width so that it can smoothly enter the hook pin to ensure that the coke can is pulled away;

[0013] The motor brake of the transverse traction device is changed from a single-side brake to a double-side brake. In order to prevent the coke tank from slipping or shifting on the track of the transverse traction device and ensure the safety factor of operation, the original single-side brake of the motor of the transverse traction device is transformed into a double-side brake working mode;

[0014] The dovetail rod that was raised at the tail of the original transverse traction device was detached and converted into a straight push mode. The design is to use a suspended dovetail rod to cover the tail of the traction rod of the transverse traction device and pull it into the air, hanging it at a 75-degree angle. However, this design has safety hazards. When the transverse traction motor brake fails, or the motor loses power, or the brake is not tightened, the dovetail rod suspended at the tail will fall by inertia, pushing the coke tank on the transverse traction track to slide forward, causing the coke tank to roll over. In order to prevent such accidents from happening, the original design was changed, the dovetail rod at the tail was detached, and a pre-buried traction rod base wheel was installed on the ground at the back, so that the traction rod can be extended and straightened to run in parallel;

[0015] Two extreme stop limits are added. In order to increase the safety and stability during the transverse traction operation, a set of head and tail stop limits are added on the opposite side of the existing limit. That is: when the empty coke tank is towed to the trolley, ensure that the "coke tank stop 2" signal is not lost; when the full tank is towed to the bottom of the lifting derrick, ensure that the "coke tank stop 2" signal is not lost, and the hoist can lift the coke tank normally to load coke; even if the detection element on one side fails, the signal can be detected on the other side, ensuring the continuous operation of the transverse traction device;

[0016] Modify the program and increase the time to ensure the normal operation of the transverse traction. During the transverse movement of the full tank, the connecting rod traction trolley shakes. At this time, the hook signal is abnormal, the hook falls prematurely, and continued traction will cause the traction trolley's travel motor to overload and stop. In response to this phenomenon, a protection program is added to the program. When the hook signal is abnormal, the traction trolley automatically stops to protect the equipment and prevent accidents, thereby improving the safety factor of the transverse traction device.

[0017] Preferably, during the process of delivering a full tank: the quenching car delivers a full tank from the coke oven area to the trolley alignment point, and the PLC system detects the "coke tank trolley alignment signal", "hoist hook opening signal", "coke tank stop signal", "APS clamping signal", and "transverse hook lifting signal" one by one. If at least one of the signals is not in place, the coke tank transverse traction device will not move, and the fault point will be reported for maintenance personnel to troubleshoot and handle the fault. After the fault troubleshooting is completed, the PLC will check the above signals one by one again until all signals are in place, and the coke tank transverse traction device will pull the coke tank to move horizontally toward the hoist derrick. During the transverse movement, the PLC detects whether the hook signal is lost. If so, it will pause the action and report the fault point for maintenance personnel to troubleshoot and handle the fault. After the fault troubleshooting is completed, the coke tank continues to move horizontally toward the hoist derrick. After the coke tank is moved horizontally into place, the PLC detects whether the coke tank stop signal under the hoist derrick is in place. If not, the hoist hook will not move, and the fault point will be reported for maintenance personnel to troubleshoot and handle the fault. After troubleshooting is completed, the hoist hook is locked and the coke tank is lifted.

[0018] Preferably, during the process of receiving the empty tank: after the coke tank is placed on the bed, the PLC system detects the "coke tank trolley alignment signal", "hoist hook opening signal", "coke tank stop signal", "APS clamping signal", and "transverse hook lifting signal" one by one. If at least one of the signals is not in place, the coke tank transverse traction device will not move, and the fault point will be reported for inspection and maintenance personnel to troubleshoot and handle the fault. After the fault investigation and processing is completed, the PLC will detect the above signals one by one again until all signals are in place, and the coke tank transverse traction device will pull the empty tank to the coke tank trolley for transverse movement. During the transverse movement process, the PLC will detect whether the hook signal is lost. If so, the action will be suspended, and the fault point will be reported for inspection and maintenance personnel to troubleshoot and handle the fault. After the fault investigation and processing is completed, the coke tank transverse traction device will continue to pull the empty tank to the coke tank trolley for transverse movement. The coke tank is in place, the coke tank stop signal on the coke tank trolley is in place, the transverse hook falls, and the quenching car has completed receiving the empty tank.

[0019] Preferably, the operation of the transverse traction device must meet the interlocking conditions: "the coke tank trolley is in normal positioning, the hoist hook opening signal is in place, the coke tank stop signal 2 is in place, the APS clamping signal is in place, and the transverse hook lifting signal is in place" before it can be started.

[0020] (III) Beneficial effects

[0021] The present invention provides an improved method for a lateral traction device of a dry coke quenching coke tank. It has the following beneficial effects:

[0022] The improved method of the CDQ coke drum transverse traction device transforms the original single-sided brake of the motor of the transverse traction device into a double-sided brake working mode, thereby preventing the coke drum from slipping and shifting on the track of the transverse traction device, and ensuring the safety factor of operation.

[0023] The dovetail rod that was raised at the tail end of the original transverse traction device rod was detached and converted into a straight push mode to prevent the coke tank trolley from slipping due to gravity inertia.

[0024] A set of head and tail stop limits are added on the opposite side of the existing limit. That is, when the empty coke tank is pulled onto the trolley, ensure that the "coke tank stop 2" signal is not lost; when the full tank is pulled under the lifting derrick, ensure that the "coke tank stop 2" signal is not lost, and the hoist can lift the coke tank normally to load coke; even if the detection element on one side fails, the signal can be detected on the other side, ensuring the continuous operation of the transverse traction device and increasing the safety and stability of the transverse traction operation.

[0025] A protection program is added to the program. When the hook signal is abnormal, the traction trolley automatically stops. During the transverse movement of a full tank, the hook signal is abnormal when the connecting rod traction trolley shakes, the hook falls early, and continued traction will cause the traction trolley's travel motor to overload and stop. This improvement prevents accidents, protects the equipment, and improves the safety factor of the transverse traction device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-3 The present invention provides a technical solution: an improved method for a CDQ coke tank transverse traction device, the specific operation is as follows:

[0031] The improvements are as follows:

[0032] Move the coke tank horizontally to the bottom of the lifting derrick without the "coke tank stop signal 2" signal;

[0033] Adjust the position of the ejector limit signal detection piece at the bottom of the coke tank trolley and lift it up 2mm in the vertical direction to ensure that the traction hook is evenly stressed and can be lifted into place smoothly;

[0034] Install a gasket on the head track of the transverse traction device to ensure that it is consistent with the flatness of the traction track;

[0035] The traction hook at the head of the transverse traction device was rectified by grinding it and reducing its width so that it can smoothly enter the hook pin to ensure that the coke can is pulled away;

[0036] The motor brake of the transverse traction device is changed from a single-side brake to a double-side brake. In order to prevent the coke tank from slipping or shifting on the track of the transverse traction device and ensure the safety factor of operation, the original single-side brake of the motor of the transverse traction device is transformed into a double-side brake working mode;

[0037] The dovetail rod that was raised at the tail of the original transverse traction device was detached and converted into a straight push mode. The design is to use a suspended dovetail rod to cover the tail of the traction rod of the transverse traction device and pull it into the air, hanging it at a 75-degree angle. However, this design has safety hazards. When the transverse traction motor brake fails, or the motor loses power, or the brake is not tightened, the dovetail rod suspended at the tail will fall by inertia, pushing the coke tank on the transverse traction track to slide forward, causing the coke tank to roll over. In order to prevent such accidents from happening, the original design was changed, the dovetail rod at the tail was detached, and a pre-buried traction rod base wheel was installed on the ground at the back, so that the traction rod can be extended and straightened to run in parallel;

[0038] Two extreme stop limits are added. In order to increase the safety and stability during the transverse traction operation, a set of head and tail stop limits are added on the opposite side of the existing limit. That is: when the empty coke tank is towed to the trolley, ensure that the "coke tank stop 2" signal is not lost; when the full tank is towed to the bottom of the lifting derrick, ensure that the "coke tank stop 2" signal is not lost, and the hoist can lift the coke tank normally to load coke; even if the detection element on one side fails, the signal can be detected on the other side, ensuring the continuous operation of the transverse traction device;

[0039] Modify the program and increase the time to ensure the normal operation of the transverse traction. During the transverse movement of the full tank, the connecting rod traction trolley shakes. At this time, the hook signal is abnormal, the hook falls prematurely, and continued traction will cause the traction trolley's travel motor to overload and stop. In response to this phenomenon, a protection program is added to the program. When the hook signal is abnormal, the traction trolley automatically stops to protect the equipment and prevent accidents, thereby improving the safety factor of the transverse traction device.

[0040] During the process of delivering a full tank: the quenching car delivers a full tank from the coke oven area to the trolley alignment point, and the PLC system detects the "coke tank trolley alignment signal", "hoist hook opening signal", "coke tank stop signal", "APS clamping signal", and "transverse hook lifting signal" one by one. If at least one of the signals is not in place, the coke tank transverse traction device will not move, and the fault point will be reported for the maintenance personnel to troubleshoot and handle the fault. After the fault is checked and handled, the PLC will check the above signals one by one again until all signals are in place, and the coke tank transverse traction device will pull the coke tank to the hoist derrick. During the transverse movement, the PLC detects whether the hook signal is lost. If so, it will pause and report the fault point for the maintenance personnel to troubleshoot and handle the fault. After the fault is checked and handled, the coke tank continues to move horizontally to the hoist derrick. After the coke tank is in place, the PLC detects whether the coke tank stop signal under the hoist derrick is in place. If not, the hoist hook will not move, and the fault point will be reported for the maintenance personnel to troubleshoot and handle the fault. After troubleshooting is completed, the hoist hook is locked and the coke tank is lifted.

[0041] During the process of receiving empty cans: After the coke can is placed on the bed, the PLC system detects the "coke can trolley alignment signal", "hoist hook opening signal", "coke can stop signal", "APS clamping signal", and "transverse hook lifting signal" one by one. If at least one of the signals is not in place, the coke can transverse traction device will not move, and the fault point will be reported for the inspection and maintenance personnel to troubleshoot and handle the fault. After the fault is troubleshooted, the PLC will check the above signals one by one again until all signals are in place, and the coke can transverse traction device will pull the empty can toward the coke can trolley. During the transverse movement, the PLC will detect whether the hook signal is lost. If so, it will pause and report the fault point for the inspection and maintenance personnel to troubleshoot and handle the fault. After the fault is troubleshooted, the coke can transverse traction device will continue to pull the empty can toward the coke can trolley. The coke can is in place, the coke can stop signal on the coke can trolley is in place, the transverse hook falls, and the quenching car has completed receiving the empty can.

[0042] The operation of the transverse traction device must meet the interlocking conditions: "The coke tank trolley is normally positioned, the hoist hook opening signal is in place, the coke tank stop signal 2 is in place, the APS clamping signal is in place, and the transverse hook lifting signal is in place" before it can be started.

[0043] Example:

[0044] Since the 9# coke oven was put into operation on September 29, the transverse traction device has been put into operation. The operation of the transverse traction device must meet the interlocking conditions: "the coke tank trolley is aligned normally, the hoist hook opening signal is in place, the coke tank stop signal 2 is in place, the APS clamping signal is in place, and the transverse hook lifting signal is in place" before it can be started. All of these are indispensable. Various problems have been exposed during the operation of the transverse traction device.

[0045] 1. The coke tank moves horizontally to the bottom of the lifting derrick without the "coke tank stop signal 2" signal:

[0046] 1 When this phenomenon occurs when the coke tank is full, the elevator cannot automatically operate to lift the coke tank. Personnel need to go to the site to confirm the position, manually operate the transverse traction device, pull the coke tank to the "coke tank stop 2" limit, and then manually operate the elevator to lift the coke tank to the loading device for coking. Although this completes the coke loading process, it greatly affects production efficiency.

[0047] 2. After the elevator is loaded with red coke, the empty can returns to the transverse traction device. When this happens, the APS mechanism will not be clamped, and the empty can receiving step cannot be completed. It is also necessary to manually operate the transverse traction device to the "coke can stop 2" limit. After the signal is in place, the coke quenching car is notified to send an empty can receiving instruction to complete the empty can receiving process. This slows down the production rhythm of the coke oven.

[0048] 3 In response to this phenomenon, the organization analyzed the cause and determined that there was slipping during operation, which led to signal loss and interruption. The brake limit of the transverse traction device was adjusted in time to ensure that there was no slipping and eliminate the hidden danger.

[0049] 2. The lateral traction hook is not lifted to the right position:

[0050] 1 After the quenching car issues the "take empty tank" or "deliver full tank" command, the APS mechanism is clamped. When the transverse hook is not lifted into place, the transverse traction device cannot move.

[0051] 2 Three methods were adopted to solve this problem.

[0052] (1) Adjust the position of the ejector limit signal detection plate at the bottom of the coke tank trolley and lift it up 2mm in the vertical direction to ensure that the traction hook is evenly stressed and can be lifted into place smoothly.

[0053] (2) Install gaskets on the head rail of the transverse traction device to ensure that it is consistent with the flatness of the traction rail.

[0054] (3) The traction hook at the head of the transverse traction device is rectified by grinding it and reducing its width so that it can smoothly enter the hook pin to ensure that the coke can is pulled away.

[0055] 3. Change the motor brake of the transverse traction device from a single-sided brake to a double-sided brake.

[0056] In order to prevent the coke tank from slipping or shifting on the track of the transverse traction device and ensure the safety factor of operation, the original single-sided brake of the motor of the transverse traction device was transformed into a double-sided brake working mode.

[0057] 4. Disconnect the dovetail rod that is raised at the tail end of the original transverse traction device rod and transform it into a straight push mode.

[0058] The design is to use a suspended dovetail rod to pull the tail rod of the lateral traction device into the air and hang it at a 75-degree angle. However, this design has safety hazards. When the brake of the lateral traction motor fails, or the motor loses power, or the brake is not tightened, the dovetail rod suspended at the tail will fall by inertia, pushing the coke tank on the lateral traction track forward and causing the coke tank to roll over. In order to prevent such accidents, the original design was changed, the dovetail rod at the tail was detached, and a pre-buried traction rod base wheel was installed on the ground behind to make the traction rod parallel, extended and straightened for operation.

[0059] 5. To ensure that the limit positions at the transverse traction device are effective, two extreme stop positions at the head and tail are added. In order to increase the safety and stability during the transverse traction operation, a set of head and tail stop positions are added on the opposite side of the existing limit positions. That is: when the empty coke tank is pulled onto the trolley, ensure that the "coke tank stop 2" signal is not lost; when the full tank is pulled under the lifting derrick, ensure that the "coke tank stop 2" signal is not lost, and the hoist can lift the coke tank normally to load coke; even if the detection element on one side fails, the signal can be detected on the other side, ensuring the continuous operation of the transverse traction device.

[0060] 6. Modify the program and increase the time to ensure the normal operation of the transverse traction.

[0061] During the full tank transverse movement, the connecting rod traction trolley shakes. At this time, the hook signal is abnormal, the hook falls prematurely, and continued traction will cause the traction trolley's travel motor to overload and stop. In response to this phenomenon, a protection program is added to the program. When the hook signal is abnormal, the traction trolley automatically stops to protect the equipment and prevent accidents, thereby improving the safety factor of the transverse traction device.

[0062] In summary, the improved method of the CDQ coke drum transverse traction device transforms the original single-sided brake of the motor of the transverse traction device into a double-sided brake working mode, thereby preventing the coke drum from slipping and shifting on the track of the transverse traction device, and ensuring the safety factor of operation.

[0063] The dovetail rod that was raised at the tail end of the original transverse traction device rod was detached and converted into a straight push mode to prevent the coke tank trolley from slipping due to gravity inertia.

[0064] A set of head and tail stop limits are added on the opposite side of the existing limit. That is, when the empty coke tank is pulled onto the trolley, ensure that the "coke tank stop 2" signal is not lost; when the full tank is pulled under the lifting derrick, ensure that the "coke tank stop 2" signal is not lost, and the hoist can lift the coke tank normally to load coke; even if the detection element on one side fails, the signal can be detected on the other side, ensuring the continuous operation of the transverse traction device and increasing the safety and stability of the transverse traction operation.

[0065] A protection program is added to the program. When the hook signal is abnormal, the traction trolley automatically stops. During the transverse movement of a full tank, the hook signal is abnormal when the connecting rod traction trolley shakes, the hook falls early, and continued traction will cause the traction trolley's travel motor to overload and stop. This improvement prevents accidents, protects the equipment, and improves the safety factor of the transverse traction device.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
