[0008] The present invention further describes that two speakers are fixedly installed on the left side of the moving block, and the two speakers are respectively connected to the two chamber pipes.
[0009] The present invention further illustrates that the operation steps of the correction system include: step S1, the coal carriage is moved by the robot, and when it moves to the tipping machine position, the limit block of the coal carriage contacts the calibration block and pushes it to slide until the sensing head moves directly above the sensor, and the information transmission module causes the sensor to receive the signal and send out information, and the robot controls the coal carriage to stop moving; step S2, the coal carriage generates inertia and moves slightly to the right, at this time it contacts the buffer rod and generates buffering, and at the same time the buffering force automatically increases the hydraulic oil pressure in the buffer chamber through the hydraulic chamber; step S3, then the motor runs, and continues to pressurize the inside of the buffer chamber by the hydraulic chamber, so that the buffer rod moves in the opposite direction, and the coal carriage is accurately calibrated; step S4, after the position correction of the coal carriage is completed, the hydraulic plate squeezes the slide rod, causing the horn to sound; step S5, the tipping machine starts to flip the coal carriage.

The coal carriage can be calibrated to avoid inaccurate positioning of the coal carriage, which may result in the coal not being fully unloaded into the coal bunker during unloading. When the inertia of the coal carriage is large, it can play a role in buffering the coal carriage. At the same time, when the correction block moves, the hydraulic oil on the right side of the hydraulic plate is squeezed and enters the buffer chamber through the pipeline, increasing its internal hydraulic pressure, thereby further enhancing the buffering force, and fully avoiding excessive movement of the coal carriage resulting in reduced correction efficiency. The hydraulic oil is squeezed into the buffer chamber by hydraulic means, and the buffer plate moves to the left along the inner wall of the buffer chamber, thereby pushing the correction block to the left through the buffer rod for secondary correction work until the sensing head is fully aligned with the sensor, so that the coal carriage is fully corrected to ensure positioning accuracy.

[0013] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0014] See also Figure 1-7 The present invention provides a technical solution: a positioning and correction system for a car tipper based on automated control, comprising a coal carriage, a car tipper, and a plurality of positioning mechanisms, each of which includes a correction system. Limit blocks are provided at the front and rear of the coal carriage, and the plurality of positioning mechanisms are installed on the car tipper and each includes a track 1, a slider 2, a correction block 3, a sensor 4, and a sensor head 5. The slider 2 is slidably connected to the inside of the track 1, the correction block 3 is fixedly installed above the slider 2 and horizontally aligned with the limit block of the coal transport car, the sensor 4 is fixedly installed below the track 1, and the sensor head 5 is fixedly installed below the slider 2 and located above the sensor 4. The correction system includes a signal transmitting module, a signal receiving module and an information transmission module. The signal receiving module is respectively connected to the information transmission module and the signal transmitting module, and the information transmission module is connected to the external robot signal. The signal transmitting module is arranged inside the sensor head 5 and is used to transmit the sensing signal. The signal receiving module is arranged inside the sensor 4 and is used to receive the sensing signal emitted by the signal transmitting module after the sensor head 5 moves to directly above the sensor 4. The information transmission module is used to send information after the sensor 4 receives the signal and control the coal transport car to stop moving through the robot; When the coal carriage enters the tipping machine position, the limit block of the coal carriage contacts the correction block 3 and pushes the correction block 3 to move. The correction block 3 slides to the right along the track 1 through the slider 2, thereby driving the sensing head 5 to move. When the sensing head 5 moves to the top of the sensor 4, the signal transmitting module transmits the sensing signal, the signal receiving module receives the sensing signal emitted by the signal transmitting module, and controls the robot through the information transmission module to stop the coal carriage from moving, thereby performing a preliminary calibration of the coal carriage. If the inertia generated by the carriage is small and there is no excessive movement to the right, the tipping machine starts to run and flips the coal carriage to dump coal. The whole process is automated and has high correction accuracy. It can calibrate the coal carriage to avoid its inaccurate position causing the coal material to not be completely poured into the coal bin when dumping coal.
[0015] A buffer cavity 11 is fixedly installed at the right end of the track 1, a buffer plate 111 is slidably connected to the inner wall of the buffer cavity 11, and a buffer rod 112 is fixedly installed on the left side of the buffer plate 111; The buffer rod 112 is horizontally aligned with the correction block 3. The right side of the buffer plate 111 is filled with hydraulic oil. A hydraulic chamber 12 is fixedly installed on one side of the track 1. A hydraulic plate 121 is slidably connected to the inner wall of the hydraulic chamber 12. The hydraulic plate 121 is spring-connected to the right side of the inner wall of the hydraulic chamber 12. A push-pull rod 31 is fixedly installed on one side of the correction block 3. The right end of the push-pull rod 31 is located on the left side of the hydraulic plate 121. The right side of the hydraulic chamber 12 is connected to the right pipe of the buffer chamber 11. The right side of the hydraulic plate 121 is also filled with hydraulic oil. When the inertia of the coal transport car is large, the sensing head 5 moves to the top of the sensor 4 and then continues to move to the right. At this time, the correction block 3 contacts the buffer rod 112 and pushes the buffer rod 112. The buffer rod 112 drives the buffer plate 111 to slide along the inner wall of the buffer chamber 11. The hydraulic oil on the right side of the buffer plate 111 is subjected to pressure to generate a reaction force, thereby buffering, which can play a role in buffering the coal transport car. At the same time, when the correction block 3 moves, it drives the push-pull rod 31 to move to the right. The push-pull rod 31 contacts the hydraulic plate 121 and pushes the hydraulic plate 121 to slide along the inner wall of the hydraulic chamber 12. The spring is deformed under force, and the hydraulic oil on the right side of the hydraulic plate 121 is squeezed and enters the buffer chamber 11 through the pipeline, thereby increasing the internal hydraulic pressure, thereby further enhancing the buffering force, and fully avoiding the excessive movement of the coal transport car and causing a decrease in correction efficiency.
[0016] A motor 13 is fixedly mounted on one side of the track 1, and a gear 131 is fixedly connected to the output end of the motor 13. A slide rail 14 is fixedly mounted on one side of the track 1, and a toothed plate 141 is slidably connected to the bottom of the slide rail 14. The toothed plate 141 and the gear 131 are meshed with each other. The right end of the tooth plate 141 is located on the left side of the hydraulic plate 121; After buffering the coal carriage, the motor 13 runs, driving the gear 131 to rotate. The gear 131 drives the tooth plate 141 to slide uniformly to the right along the slide rail 14 through engagement until the tooth plate 141 contacts the left side of the hydraulic plate 121 and pushes the hydraulic plate 121 to move further to the right, thereby squeezing the hydraulic oil into the buffer chamber 11 by hydraulic means, and the buffer plate 111 moves to the left along the inner wall of the buffer chamber 11, thereby pushing the correction block 3 to move to the left through the buffer rod 112, and performing secondary correction work until the sensor head 5 is fully aligned with the sensor 4, so that the coal carriage is fully corrected to ensure positioning accuracy.
[0017] A slot 311 is provided in the middle of the push-pull rod 31, and a moving block 312 is slidably connected to the outer surface of the slot 311. The moving block 312 is fixedly connected to one side of the track 1; Two chambers 313 are fixedly mounted on the right side of the moving block 312. The inner walls of the two chambers 313 are slidably connected to slide plates 314. A slide bar 315 is fixedly mounted on the right side of the slide plates 314. The slide plates 314 are spring-connected to the left inner walls of the chambers 313. After the cam 314 is in the state of being moved, the cam 314 will move in the opposite direction to the left, and the cam 314 will move in the opposite direction to the right.
[0018] Two speakers 316 are fixedly installed on the left side of the moving block 312, and the two speakers 316 are respectively connected to the pipes of the two chambers 313; Through the above steps, when the slide 314 slides to the left along the inner wall of the chamber 313, the gas on the left side of the slide 314 is squeezed and enters the speaker 316 through the pipe, causing the speaker 316 to sound, thereby reminding the operator that the position between the coal transport car and the tipper has been corrected and the coal can be dumped. It can also remind the operator to stay away from the tipper to avoid safety accidents.
[0019] The steps for operating the calibration system include: Step S1: The coal carriage is moved by the robot. When it moves to the tipping machine position, the limit block of the coal carriage contacts the calibration block 3 and pushes it to slide until the sensing head 5 moves directly above the sensor 4. The sensor 4 receives the signal through the information transmission module and sends a message, and the robot controls the coal carriage to stop moving. Step S2: The coal carriage moves slightly to the right due to inertia, and then contacts the buffer rod 112, generating a buffer. At the same time, the buffering force automatically increases the hydraulic oil pressure in the buffer chamber 11 through the hydraulic chamber 12; Step S3: The motor 13 then operates to continue pressurizing the hydraulic chamber 12 against the buffer chamber 11, causing the buffer rod 112 to move in the opposite direction, thereby precisely calibrating the coal carriage. Step S4: After the position of the coal carriage is corrected, the hydraulic plate 121 squeezes the slide bar 315, causing the speaker 316 to emit a sound. Step S5: The car tipper starts to flip the coal carriage.
[0020] In steps S1 to S4, the sensor 4 and the sensor head 5 are firstly calibrated, the hydraulic chamber 12 and the buffer chamber 11 are then used for buffering, and the motor 13 is then used for secondary calibration. Finally, the horn 316 is sounded after the calibration is completed. Automated positioning correction of the position between the coal carriage and the dumper can ensure the correction accuracy to the greatest extent. Through secondary correction, the position between the coal carriage and the dumper can be kept at high precision to avoid accidents in coal dumping. The whole process is more intelligent and the coal unloading efficiency of the dumper is greatly improved.
