Description

Technical Field

[0001] This invention relates to the field of railway transportation systems, and in particular to an automatic weighing and tipping system for railway transportation. Background Technology

[0002] Railway transportation is a mode of transport that uses railway trains to carry passengers and goods. It plays an important role in the social material production process. Its characteristics include large transport capacity, high speed, low cost, and generally no restriction by weather conditions. It is suitable for long-distance transport of bulk and heavy goods. During railway transportation, a tipping device is needed to weigh and unload the carriages. A tipping device is a large mechanical device used to unload bulk materials from open railway wagons. It is a loading and unloading machine that can tilt or tilt rail vehicles to unload materials. It is suitable for ports with large transport volumes and industrial sectors such as metallurgy, coal, and thermal power.

[0003] With the development of the railway transportation industry, efficient loading and unloading and automated management of freight trains have become key to improving logistics efficiency. Traditional railway freight car weighing and unloading (such as bulk materials like coal and ore) suffers from a fixed and singular method, which is impractical for cars of different specifications. Furthermore, the tilting and unloading process is prone to displacement, affecting safety. Additionally, the internal cleaning structure of the car is inadequate, leading to residue issues during unloading. Untreated dust generated during unloading also causes environmental pollution. Therefore, an automatic weighing and tipping system for railway transportation is proposed. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an automatic weighing and tipping system for railway transportation. This system achieves smooth and automatic tipping of the carriages through a gear-ring transmission mechanism, and works in conjunction with a built-in rail scale to complete simultaneous weighing and unloading operations, significantly improving operational efficiency. Multi-dimensional fixing units are used to ensure the stability of the carriages during weighing and tipping. Furthermore, intelligent cleaning and dust removal units (such as adjustable sweeping brushes, negative pressure suction, and atomized dust suppression) are integrated to achieve automatic cleaning of the carriages, reducing material residue and dust pollution, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic weighing and tipping system for railway transportation, comprising a base and a track scale:

The input ends of the first electric push rod, the second motor, and the third motor are electrically connected to the output end of the controller. The third motor is started to drive the second lead screw to rotate to adjust the distance between the two pressure frames. The second motor drives the first lead screw to rotate to move the pressure frame to the top surface of the carriage.

The right end of the hydraulic rod is connected to one end of the left side of the limiting plate. The first linear motor is installed in each of the two grooves on the right side of the limiting plate. The surface of the first linear motor's actuator is provided with a clamping plate. The input ends of the hydraulic rods and the first linear motors are electrically connected to the output end of the controller. The hydraulic rods drive the limiting plate to fit against the side of the carriage, thus providing support during the carriage's tilting process. The first linear motor drives the clamping plate to clamp the sides of the carriage, improving the carriage's fixing stability.

[0011] Furthermore, the fixing unit also includes a laser rangefinder, a frame, and a detection camera. The laser rangefinder is installed in the middle of the right side of the limiting plate.

The sponge strips are evenly distributed on the right side of the limiting plate, the main anti-slip pads are bonded to the inner side of the clamping plate, and the secondary anti-slip pads are bonded to the inside of the pressure frame. The main and secondary anti-slip pads can increase the firmness of the carriage, while the sponge strips can reduce the wear on the surface of the carriage when it is tilted.

[0017] Furthermore, it also includes a wireless transmitter, which is fixed to the top surface of the base. The output of the wireless transmitter is electrically connected to the input of the controller. The wireless transmitter can transmit the detected data to the personnel's electronic devices in real time, so as to facilitate personnel to view, adjust and maintain it.

The first linear motor drives the clamping plate to clamp the sides of the carriage, improving the stability of the carriage. The hydraulic rod drives the limit plate to fit against the side of the carriage, thus providing support during the carriage's tilting process. This method can fix carriages of different specifications.

[0020] 2. Adjust the height of the sweeping brush by activating the electric telescopic rod, while the pneumatic push rod allows the sweeping brush to fit against the inner wall of the truck bed. Then, activate the second linear motor to move the sweeping brush back and forth to quickly clean the inner wall of the truck bed and thoroughly remove any residue. Activate the second electric push rod to make the sponge pad fit against the surface of the truck bed, and the vibration motor, in conjunction with the spring, generates high-frequency vibrations to tap the truck bed and remove any remaining materials inside.

Simultaneously, the third motor 29 is activated to rotate the second lead screw 28 to adjust the distance between the two pressure frames 23. The second motor 26 drives the first lead screw 27 to rotate, moving the pressure frame 23 to the top surface of the carriage. The first electric push rod 21 pushes the pressure frame 23 down to secure the carriage. The main anti-slip pad 16 and secondary anti-slip pad 17 further enhance the carriage's stability. Meanwhile, the sponge strip 15 reduces wear on the carriage surface during tilting. The first motor 13 is activated to engage the gear 12 with the gear ring 7, and... The load-bearing roller 5 is engaged with the wheel groove on the outer side of the ring frame 6 to drive its rotation, thus emptying the materials inside the truck bed. The electric telescopic rod 33 is activated to adjust the height of the sweeping brush 38, while the pneumatic push rod 36 allows the sweeping brush 38 to fit against the inner wall of the truck bed. At this time, the second linear motor 32 is activated to drive the sweeping brush 38 to move back and forth to quickly clean the inner wall of the truck bed and thoroughly remove the residue. Simultaneously, the second electric push rod 316 is activated to make the sponge pad 312 fit against the surface of the truck bed, and the vibration motor 314, in conjunction with the spring 317, generates high-frequency vibration to tap the truck bed. To remove residual materials inside the carriage, during the tipping and unloading process, the negative pressure fan 43, in conjunction with the dust suction pipe 41, sucks the dust generated during the tipping process into the filter box 45, where it is filtered by the activated carbon placed inside. At the same time, the external water pump, in conjunction with the atomizing spray pipe 46, generates water mist to suppress dust dispersion, thereby reducing environmental pollution. Finally, after the ring frame 6 reverses and returns to its original position, the weight of the carriage is detected. Thus, the total weight of the materials inside the carriage can be obtained. The wireless transmitter 18 can transmit the detected data to the personnel's electronic devices in real time, so that personnel can view, adjust, and maintain it.
