Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator for dry coke quenching and a positioning method thereof. Background Art
[0002] The dry coke quenching elevator is a special conveying equipment. The dry coke quenching elevator is a device that takes the coke out from the bottom of the coke oven and lifts it to the upper equipment for transportation through an elevator. It is mainly used to lift the coke tank filled with red coke (high-temperature coke) transported to the top of the derrick, and walk along the track set above the dry quenching tower, transport the red coke tank to the top of the set dry quenching tower loading device, and then slowly roll the red coke tank down and sit on the loading device. The gate at the bottom of the coke tank will open automatically to load the red coke into the dry quenching tower. After the coke loading is completed, the empty coke tank will be rolled up and returned to the top of the lifting derrick, and the empty coke tank will be rolled down and sent back to the carrier to receive the coke; according to the different structures and characteristics, the dry coke quenching elevator can be divided into chain dry coke quenching elevator, scraper dry coke quenching elevator, disc dry coke quenching elevator and other types.
[0003] The working principle of the CDQ elevator is to evenly cool the high-temperature coke through cooling air to achieve the purpose of controlling the coke temperature, reducing coke cracking, and reducing production losses. There are multiple sets of nozzles in the CDQ elevator to release cooling gas blown from the dryer to evenly cool the coke. The cooled coke is transported and separated through the elevator to improve the coke quality and reduce heat loss.
[0004] After searching, the patent application document with the prior art publication number CN102515034A proposed a dry coke quenching elevator and elevator positioning method. The elevator includes a lifting mechanism and a translation mechanism, and a control system PLC / DCS. The lifting mechanism and translation mechanism are provided with multiple encoders, and data collection is realized through the encoders to complete the lifting and translation distance measurement of the elevator, and the measured distance measurement value is transmitted to the control system PLC / DCS; the control system PLC / DCS positions the operation of the elevator according to the received distance measurement value. By using a pulse absolute value encoder with DP bus function to measure the lifting and translation distance of the elevator, the positioning of the elevator is completed, the positioning accuracy of the elevator operation is improved, and the faults caused by inaccurate positioning during the operation conversion and fixed-point stop of the elevator are greatly reduced. At the same time, the limit switch is combined to perform auxiliary positioning, which further ensures the safety of the production operation of the elevator, thereby further improving the reliability and stability of the operation of the elevator system.
[0005] Compared with the above documents, in the above documents, the lifting and translation distance of the elevator is measured by using a pulse absolute encoder with DP bus function to complete the positioning of the elevator, which improves the positioning accuracy of the elevator operation and greatly reduces the failure of the elevator due to inaccurate positioning during operation conversion and fixed-point stop. At the same time, the limit switch is combined for auxiliary positioning to further ensure the safety of the production operation of the elevator, thereby further improving the reliability and stability of the operation of the elevator system. However, the power mechanism in the positioning method of the dry coke quenching elevator in the above document is used in a single way to realize the working principle, thereby reducing the production efficiency of the dry coke quenching elevator, increasing the production cost of the dry coke quenching elevator, and reducing the production safety of the dry coke quenching elevator. For this reason, a dry coke quenching elevator and a positioning method thereof are proposed. Summary of the invention
[0006] The object of the present invention is to provide a dry coke quenching elevator and a positioning method thereof, so as to solve the problem that the power mechanism in the current positioning method of the dry coke quenching elevator is used in a single manner to realize the working principle, thereby reducing the production efficiency of the dry coke quenching elevator, increasing the production cost of the dry coke quenching elevator, and reducing the production safety of the dry coke quenching elevator.
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] A dry quenching elevator comprises a control system and a power mechanism, wherein the power mechanism comprises a driving motor, a reducer, a clutch, a transmission shaft brake and a power encoder;
[0009] The present invention further specifically describes that the driving motor and the reducer are connected through a coupling, the reducer and the transmission shaft are driven through an output shaft and a gear, the clutch and the driving motor are switched manually and automatically, the transmission shaft and the brake can perform safe braking, and the encoder and the power mechanism can perform position feedback and speed detection;
[0010] As can be seen from the above, in the positioning method of the dry coke quenching hoist, the optimized coordination between the various components of the power mechanism brings many benefits. The following are the benefits of the coupling connection between the drive motor and the reducer, the transmission between the reducer and the transmission shaft through the output shaft and gears, the manual and automatic switching between the clutch and the drive motor, the safe braking between the transmission shaft and the brake, and the position feedback and speed detection between the encoder and the power mechanism:
[0011] The coupling is used to connect the drive motor and the reducer. The coupling can ensure the maximum energy transfer efficiency between the drive motor and the reducer and reduce energy loss. The coupling has a certain buffering and vibration reduction effect, which can reduce the vibration and impact between the drive motor and the reducer and protect the equipment from damage. By optimizing the connection of the coupling, the stability of the entire power system can be improved, ensuring the stable operation of the hoist in a complex environment.
[0012] The reducer and the transmission shaft are connected by the output shaft and gear transmission. The reducer accurately transmits the torque of the drive motor to the transmission shaft through the output shaft and gear transmission to ensure that the motion trajectory and speed of the elevator meet the requirements. The gear transmission has a high transmission efficiency, which can reduce energy loss and improve the operating efficiency of the elevator. By optimizing the design and manufacture of the gear transmission, the reliability of the system can be improved, the failure rate can be reduced, and the continuous operation of the elevator can be ensured;
[0013] The clutch can realize manual and automatic switching between the drive motors through manual and automatic switching between the clutch and the drive motor, which improves the flexibility of the system and can meet the needs of different working conditions. In an emergency, the clutch can quickly cut off the power transmission to protect the equipment from damage and ensure the safety of personnel. By optimizing the design and manufacturing of the clutch, its failure rate can be reduced, maintenance costs can be reduced, and the availability of the equipment can be improved;
[0014] The transmission shaft and the brake are used for safe braking. The brake can ensure that the transmission shaft stops quickly and accurately when it needs to stop, thereby ensuring the accurate positioning of the elevator. The safety braking function of the brake can prevent the elevator from continuing to move in unexpected situations and avoid safety accidents. By optimizing the design and manufacture of the brake, the stability of the system can be improved and the vibration and impact caused by poor braking can be reduced;
[0015] By performing position feedback and speed detection between the encoder and the power mechanism, the encoder can monitor the position and speed information of the drive shaft in real time, and feed this information back to the control system to achieve precise control. The position feedback function of the encoder can improve the positioning accuracy of the elevator and meet more stringent process requirements. The real-time data provided by the encoder can help factory managers analyze the operating status of the elevator, promptly discover and correct problems in the production process, and thus optimize the production process.
[0016] The drive motor, reducer, clutch, transmission shaft, brake and encoder are arranged inside the power mechanism to optimize the coordination, which has the following benefits:
[0017] The encoder can monitor the position information of the transmission shaft in real time and feed this information back to the control system. Through optimized coordination, the control system can more accurately adjust the output of the drive motor according to the feedback signal of the encoder, thereby achieving precise positioning of the elevator.
[0018] The optimized coordination among the components can reduce the errors caused by improper installation, wear or adjustment. The reduction of these errors helps to improve the overall positioning accuracy of the elevator, so that it can meet more stringent process requirements.
[0019] The optimized coordination between the drive motor and the reducer can reduce energy loss and improve power transmission efficiency; it helps to reduce energy consumption, improve the operating efficiency of the elevator, and reduce downtime. Through optimized coordination, the downtime caused by component failure or wear can be reduced, which helps to maintain the continuous operation of the elevator and improve production efficiency; the optimized coordination between the components can reduce the stress concentration and wear caused by vibration and impact, which helps to extend the service life of the components and improve the stability of the system. Through optimized coordination, the system's resistance to external interference (such as temperature, humidity, electromagnetic interference, etc.) can be improved, which helps to maintain the stable operation of the system and reduce the possibility of failure;
[0020] The optimized coordination between the components can reduce the damage caused by friction and wear, and help reduce the replacement frequency and maintenance cost of components. Through optimized coordination, the maintenance process can be simplified, the maintenance difficulty can be reduced, and the maintenance time and maintenance cost can be reduced, and the availability of equipment can be improved. The optimized coordination between the brake and the drive shaft can improve the braking performance, ensure that the hoist can respond in time when it needs to stop or slow down, and help prevent safety accidents caused by brake failure. Through optimized coordination, the protection ability between the components can be enhanced to prevent safety hazards caused by loose or falling components.
[0021] In summary, by optimizing the coordination among the drive motor, reducer, clutch, transmission shaft, brake and encoder inside the power mechanism in the positioning method of the CDQ elevator, it is possible to effectively improve positioning accuracy, improve operating efficiency, enhance system stability, reduce maintenance costs and ensure safety. The realization of these benefits helps to meet various needs in the CDQ production process, improve production efficiency, reduce production costs and ensure production safety.
[0022] The control system includes an absolute value encoder, a position detection switch, an electric transmission control system, an auxiliary equipment control system and a signal transmission cable trolley;
[0023] The present invention further specifically describes that the position detection switch is used to set the lifting stroke, lifting speed change point, upper and lower limits of the stroke, lateral operation range, travel speed change point and parking position of the hoist; the control system is used to monitor the operating status of the hoist in real time; the absolute encoder is a pulse setting with a DP bus function; the control system monitors the operating status of the hoist in real time, including position, speed and acceleration; the electric transmission control system includes a power supply control cabinet, a rectifier feedback device, a lifting inverter device and a travel inverter device; the electric transmission control system is used to provide power and control for the hoist; the electric transmission control system adopts a variable frequency speed control mode with an energy feedback function to work; the auxiliary equipment control system includes lighting, lubrication, ventilation and maintenance electric hoists; the signal transmission cable trolley is used to transmit the signals of the absolute encoder and the position detection switch to the control room or the remote monitoring center;

The control system can be integrated with other production systems or equipment to realize information sharing and collaborative operation;
[0026] The absolute encoder can provide high-precision position information to ensure the accurate positioning of the hoist in a complex environment. The absolute encoder relies on mechanical position to determine the encoding, without the need for memory function, which improves the reliability and response speed of the system. The absolute encoder has high anti-interference ability and can operate stably in harsh environments to ensure data accuracy. The absolute encoder has a compact structure, is easy to install, and is easy to maintain and replace.
[0027] The position detection switch can monitor the position of the hoist in real time and automatically stop when it reaches the preset position to prevent equipment damage. The position detection switch can ensure that the hoist stops safely at a specific position to avoid safety accidents. The position detection switch is small in size, easy to install, and easy to integrate with the existing system;
[0028] The electric drive control system adopts variable frequency speed regulation technology, which can automatically adjust the motor speed according to load changes to achieve high efficiency and energy saving. The electric drive control system has complete protection measures and fault diagnosis functions to ensure the stable operation of the hoist. The electric drive control system has a clear structure, is easy to maintain and manage, and reduces maintenance costs;

Through reasonable control and maintenance, the auxiliary equipment control system can extend the service life of the equipment and reduce replacement costs. The stable operation of the auxiliary equipment control system can ensure the continuous operation of the production line and improve production efficiency.
[0030] The signal transmission cable trolley can ensure the stable transmission of cables and signal lines during the movement of the hoist, avoiding signal interruption or distortion. The signal transmission cable trolley has the function of protecting the cables and can prevent the cables from being damaged due to friction, extrusion, etc. The signal transmission cable trolley is flexibly designed and can adapt to the movement requirements of hoists at different heights and angles.
