Description

Technical Field

[0001] This invention relates to the field of bulk material sampling technology, specifically to a follow-up anti-reverse fully automated sampling device and its sampling method. Background Technology

[0002] With the development of automation control technology for industrial equipment in my country, large and medium-sized coal production enterprises and coal-consuming units such as power plants are striving to improve their automation levels to enhance work efficiency and operational quality. The market has developed sampling devices capable of automatic random sampling. These devices typically include a sampling head and a moving and lifting mechanism. The entire system is automatically controlled by a PLC, which provides counting and position information for the moving and lifting mechanisms. With just a click of the mouse, the sampling device automatically samples according to pre-set parameters such as the number of sampling attempts and the location of sampling points. This significantly improves the scientific rigor and efficiency of sampling. Currently, mainstream automated train sampling devices primarily target incoming coal, employing a fixed sampling method that requires the train carriages to remain stationary, and are widely used in power plants. However, in large coal mines and coal washing plants in my country, coal trains are loaded while being pulled by a traction locomotive. This necessitates that the sampling device possess a dynamic sampling function, enabling rapid sampling during vehicle movement to improve sampling efficiency. Furthermore, considering that coal trains may suddenly accelerate or reverse to reload under special circumstances, the sampling device should also be able to automatically identify train acceleration or reversing and avoid collisions with the carriages. When multiple carriages reverse continuously at once, the sampling device should be able to identify the carriages that have already been sampled, avoid resampling the reversing carriages, and retract the sampling head to prevent collisions with the carriages. Existing technologies cannot solve the problem of automatic identification and avoidance of train reversing; when encountering reversing, one can only manually press the emergency stop button or manually click to change the sampling point, which cannot achieve truly fully automated sampling without human intervention. A comprehensive and reliable follow-up anti-reversing sampling device is urgently needed in the field of bulk solid mineral sampling in my country.

[0003] Chinese invention patent application number CN201810133565.5 discloses a train sampling system with follow-up function. This technical solution adopts train synchronization technology and uses PLC to control the sampler to maintain a relative speed of zero with the train carriage during sampling, ensuring that the sampling head does not contact the carriage. This technical solution achieves follow-up sampling to a certain extent. However, since the mobile sampling device must be installed on the rail, it needs to leave space for movement, which occupies a large amount of working space and valuable land space. Moreover, after sampling each carriage, the sampler must return to the initial position and maintain the same speed with the train again to collect coal samples from another carriage. The operation steps are complicated, time-consuming, and prone to missed sampling.

[0004] Chinese utility model patent application number CN200520074662.X discloses a dynamic coal sampling device, which is a technical solution for sampling on the top of a moving train car. It enables sampling while the train is being loaded, but the device cannot sample randomly and does not have an anti-reverse function. Summary of the Invention

[0005] In my country, coal trains transporting coal to large coal mines and coal washing plants (outgoing coal) are loaded while being pulled by locomotives, but existing mechanical sampling devices on the market can only sample from a stationary position. The following-motion anti-reverse fully automated sampling device and its sampling method provided by this invention have a following-motion sampling function, solving the technical problem that current equipment cannot operate online, and require no additional sampling track, thus occupying a small area.

[0006] Existing technologies cannot solve the problem of automatic identification and avoidance of sudden train acceleration or reversing. When encountering sudden acceleration or reversing, one can only manually press the emergency stop button or manually click to change the sampling point. The follow-up anti-reversing fully automated sampling device and its sampling method provided by this invention can automatically identify the train's speed and direction. When the train suddenly accelerates or reverses, no matter where the sliding trolley is, the sampling head will stop sampling and lift up, and the trolley traveling mechanism will return to the origin, avoiding the carriage body and preventing a collision.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A follow-up anti-reverse fully automated sampling device includes an operation monitoring device, a fully automated sampling central control system, an electronic and hydraulic device for operating each system, and a sampling device.

[0009] The operation monitoring device includes several sensors and detectors installed on both sides of the train track and on the sampling device for acquiring information on train speed, carriage gap, carriage size, and train reversing operation.

[0010] The fully automatic sampling control system is connected to the operation monitoring device and the sampling device. It is used to control the sampling device to complete sampling within the time it takes for the train carriage to pass through, and to avoid the risks of acceleration and reversing, based on various train operation information obtained by the operation monitoring device.

[0011] The sampling device includes a bridge frame fixed above the train track, a trolley traveling mechanism that can slide horizontally on the bridge frame, and a sampling head that can be raised and lowered on the trolley traveling mechanism for collecting samples on a moving train car.

[0012] Preferably, the sensors and detectors are connected to the input interface of the central processing unit (PLC) of the fully automatic sampling control system; the sensors and detectors are used to acquire information on the train's forward direction, running speed, carriage gap, carriage size, and train reversing operation, and transmit the information to the central processing unit (PLC).

[0013] Preferably, the sampling device also includes a speed sensor and a speed detector connected to the central processing unit (PLC) for monitoring the speed of the carriage.

[0014] Preferably, the trolley traveling mechanism includes a sliding trolley, a longitudinal slide rail and a transverse guide rail disposed on the bridge frame; the longitudinal slide rail and the transverse guide rail are arranged perpendicularly to each other, the sliding trolley can slide on the longitudinal slide rail and the transverse guide rail, and the sampling head is mounted on the sliding trolley and slides along the longitudinal slide rail and the transverse guide rail with the sliding trolley.

[0015] Preferably, the bridge frame is equipped with a working platform.

[0016] A follow-up, fully automated sampling method for preventing reverse parking includes the following steps:

[0017] Ensure that the train carriages can run on the train tracks;

[0018] The bridge frame of the sampling device is fixed above the train track, the trolley traveling mechanism is slidably installed on the bridge frame, and the sampling head for collecting samples on the moving train carriage is installed on the trolley traveling mechanism in a liftable manner.

[0019] The sensors and detectors used to acquire information on train speed, carriage clearance, carriage size, and train reversing are installed on both sides of the train track and on the sampling device in the operation monitoring device.

[0020] The fully automatic sampling control system, which is connected to the operation monitoring device and the sampling device and is used to control the sampling device to complete sampling within the time of train carriage passage and avoid the risks of acceleration and reversing based on various train operation information obtained by the operation monitoring device, will be debugged. After debugging, the sensors and detectors will be connected to the input interface of the central processing unit (PLC) of the fully automatic sampling control system to obtain the train's forward direction, running speed, carriage gap, carriage size, and train reversing operation information, and transmit the information to the central processing unit (PLC).

[0021] The central processing unit (PLC) acquires the information and performs A / D conversion on the information;

[0022] The central processing unit (PLC) determines whether the coal train is traveling at a normal and uniform speed and whether it meets the sampling conditions.

[0023] If the coal train is moving at a normal and constant speed, and the time it takes for a certain carriage to pass the sampling device meets the sampling requirements, the central processing unit PLC will randomly determine a sampling point in the carriage.

[0024] The central processing unit (PLC) outputs a sampling instruction corresponding to the determined sampling point position to the sampling device.

[0025] The sampling device acquires the sampling instruction and moves directly above the sampling point location to perform sampling according to the sampling instruction.

[0026] Preferably, the sampling device further includes a speed sensor and a speed detector connected to the central processing unit PLC for monitoring the speed of the carriage;

[0027] If the car body suddenly accelerates in the forward direction, the central processing unit (PLC) determines the distance between the rear of the coal car body and the sampling head that is in operation based on the acceleration of the car body.

[0028] If the central processing unit (PLC) determines that the distance between the rear of the acceleration carriage and the sampling head in operation is sufficient for the sampling head to continue the entire sampling process, the central processing unit (PLC) will not output a correction command to the sampling head.

[0029] If the central processing unit (PLC) determines that the distance between the rear of the acceleration carriage and the sampling head in operation is insufficient for the sampling head to continue completing the entire sampling process, the PLC will output a stop sampling command to the sampling head.

[0030] Regardless of the position of the sliding trolley, once the sampling head receives a stop sampling command, it will stop sampling and lift up, causing the trolley's traveling mechanism to return to its origin, avoiding the rear of the carriage and preventing a collision.

[0031] Preferably, if the coal train car suddenly reverses, regardless of the reversing speed, the central processing unit (PLC) will output a stop sampling command to the sampling head.

[0032] Regardless of the position of the sliding trolley, once the sampling head receives a stop sampling command, it will stop sampling and lift up, causing the trolley's traveling mechanism to return to its origin, avoiding the head of the carriage and preventing a collision.

[0033] Preferably, when the train is running normally, the sensors and detectors automatically collect the carriage passing signals, and the central processing unit (PLC) counts the number of carriages passing based on the collected signals; when the train is reversing, the sensors and detectors automatically collect the carriage passing signals in the opposite direction, and the central processing unit (PLC) automatically reduces the number of carriages passing based on the collected signals.

[0034] After the coal train resumes normal travel from the reversing state, the sensors and detectors continue to automatically collect the car passing signals. The central processing unit (PLC) continues to increase the number of cars passing on the basis of the reduced number of cars reversing. The central processing unit (PLC) will not output sampling instructions to the sampling device.

[0035] When the number of carriages is restored to the same level as before reversing, the central processing unit (PLC) randomly determines sampling points within the carriages.

[0036] The central processing unit (PLC) outputs a sampling instruction corresponding to the determined sampling point position to the sampling device.

[0037] The sampling device receives the sampling instruction and moves directly above the sampling point according to the sampling instruction to continue sampling. This process is repeated to complete the sampling of all coal-loading cars in the train.

[0038] The fully automated anti-reverse sampling device and sampling method provided by this invention can realize full-process automated sampling, automatically identify reversing risks, and eliminate the need for human intervention, thereby improving work efficiency and reducing manual labor intensity and potential dangers.
