All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment

[0035] Next, the present utility model will be further described in conjunction with the accompanying drawings.

[0036] As Figure 1 shown, an automated track transportation system provided in this embodiment includes:

[0037] Track 14, which is laid between Process 11 and Process 12;

[0038] Track transport vehicle 15, which travels on track 14;

[0039] Infrared limit device, which is arranged at both ends of track transport vehicle 15, and both the infrared limit device and track transport vehicle 15 are connected to controller 4.

[0040] The working principle and beneficial effects of the present utility model are:

[0041] An automated rail transportation system provided in this embodiment lays rail 14 between two fixed processes according to design requirements, and designs and manufactures rail transport vehicle 15; during transportation, rail transport vehicle 15 is placed on rail 14, and an operator of process one 11 steadily places the processed heavy workpiece on rail transport vehicle 15 through a crane. The operator of process two 12 remotely controls rail transport vehicle 15 to transport the workpiece to a preset position of process two 12. After the operator of process two 12 unloads the workpiece, the operator then remotely controls rail transport vehicle 15 to return to the preset position of process one 11. All operations are handled by the operator at process two 12. The working position of rail transport vehicle 15 is judged by an infrared limit device. After reaching the preset position, controller 4 automatically terminates the operation of rail transport vehicle 15, ensuring the accurate position of rail transport vehicle 15, facilitating the simultaneous loading and unloading of multiple objects and batch transportation, and significantly improving work efficiency.

[0042] As Figures 1-3 shown, in one embodiment, rail transport vehicle 15 includes: load-bearing plate 1, rail wheels 2, battery 3, controller 4, transmission assembly and servo motor 6; rail wheels 2 are connected to both sides of the bottom end of load-bearing plate 1 and roll along rail 14; battery 3, controller 4 and servo motor 6 are connected inside load-bearing plate 1, and both servo motor 6 and battery 3 are connected to controller 4. The output shaft of servo motor 4 is connected to the axle of rail wheel 2 through the transmission assembly.

[0043] The transmission assembly can be set as a chain drive. The transmission assembly includes a sprocket and transmission chain 5. Sprockets are connected to both the axle of rail wheel 2 and the output shaft of servo motor 6, and transmission chain 5 is connected to both sprockets at the same time.

[0044] The working principle and beneficial effects of the above technical solution are as follows:

[0045] When rail transport vehicle 15 travels, controller 4 controls the operation of servo motor 6. The sprocket on the output shaft of servo motor 6 rotates, drives the sprocket on the axle of rail wheel 2 through transmission chain 5, makes the axle of rail wheel 2 rotate accordingly, and further realizes the drive of rail wheel 2. Rail wheel 2 drives load-bearing plate 1 to move along rail 14, realizing the transportation of the workpiece on load-bearing plate 1. Load-bearing plate 1 is used to carry heavy workpieces, controller 4 is used to control the start and stop of servo motor 6, and battery 3 provides electrical energy for the operation of servo motor 6.

[0046] In one embodiment, the infrared limit device includes a first limit device A and a second limit device B. The first limit device A and the second limit device B are respectively connected to both ends of the same side of load-bearing plate 1, and the first limit device A and the second limit device B are connected to controller 4.

[0047] The first limit device A and the second limit device B are set as infrared sensors.

[0048] On process one 11, there is a first limit point a corresponding to the first limit device A, and on process two 12, there is a second limit point b corresponding to the second limit device B.

[0049] Limit blocks are provided at the first limit point a and the second limit point b.

[0050] The described automated rail transportation system further includes: a limit light 16, and the limit light 16 is connected to the controller.

[0051] The described automated rail transportation system further includes: a control panel, which is arranged within the workstations of process one 11 and process two 12, and the control panel is connected to the controller 4.

[0052] The working principle and beneficial effects of the above technical solution are as follows:

[0053] The heavy workpiece processed by process one 11 is smoothly placed on the load-bearing plate 1 by a crane. Then, the operator of process two 12 remotely controls the rail transport vehicle 15 to transport the workpiece to process two 12. When the rail vehicle reaches the second limit point b at process two 12, the second limit device B uses infrared sensing technology to detect the limit block provided at the second limit point b, indicating that the rail transport vehicle 15 has reached the preset position of process two 12. The controller 4 controls the limit light 16 to turn on and controls the rail transport vehicle 15 to automatically stop running. After the operator at process two 12 operates the crane to unload the workpiece, the rail transport vehicle 15 is remotely controlled to return to process one 11. When the rail vehicle reaches the first limit point a at process one 11, the first limit device A uses infrared sensing technology to detect the limit block provided at the first limit point a, indicating that the rail transport vehicle 15 has reached the preset position of process one 11. The controller 4 controls the limit light 16 to turn on and controls the rail transport vehicle 15 to automatically stop running. By using the infrared limit device to judge the working position of the rail transport vehicle 15, no manual supervision is required, and the function of automatic parking is realized. The positioning effect of the rail transport vehicle 15 is better, and the workpiece is accurately transported to the preset position, improving the operation efficiency.

[0054] In one embodiment, a storage 13 is provided between process one 11 and process two 12.

[0055] As Figure 4 、 Figure 5 shown, in one embodiment, the described automated rail transportation system further includes: positioning plates 21, two positioning plates 21 are respectively arranged within process one 11 and process two 12, a plurality of positioning holes 22 are evenly arranged on the positioning plates 21, and the positioning holes 22 are set as countersunk holes;

[0056] Positioning columns 23, a plurality of positioning columns 23 are respectively connected to both ends of the load-bearing plate 1.

[0057] At the bottom of the positioning hole 22, an electromagnetic plate 24 is connected. The positioning post 23 is set as a magnetic post. The electromagnetic plate 24 is connected to the controller 4. After the electromagnetic plate 24 is powered on, it attracts the positioning post 23.

[0058] The working principle and beneficial effects of the above technical solution are as follows:

[0059] Positioning plates 21 are provided at positions near the limit points in both the first process 11 and the second process 12. After the rail transport vehicle 15 stops running, the rail transport vehicle 15 approaches the positioning plate 21, and its two positioning posts 23 are inserted into the positioning holes 22 of the positioning plate 21. The positioning holes 22 are set as countersunk holes. When there is a slight deviation between the positioning post 23 and the positioning hole 22, the positioning post 23 slides along the countersunk part into the positioning hole 22, playing a role in correcting the deviation.

[0060] When the infrared limit device detects the in-place signal, the controller 4 simultaneously powers on the electromagnetic plate 24 to attract the positioning post 23, assisting the positioning post 23 to enter the positioning hole 22 more smoothly and without separation, thereby quickly fixing the rail transport vehicle 15.

[0061] Through the above structural design, the parking position of the rail transport vehicle 15 is more accurate, and at the same time, the stability of the rail transport vehicle 15 after parking is improved, reducing the situation of the vehicle body shaking during sudden stops.

[0062] In one embodiment, the positioning plate 21 further includes: a buffer groove 25, a guide post 26, a sleeve 27, a buffer plate 28, and a spring 29; the buffer groove 25 is provided at the center of the side of the positioning plate 21 close to the load-bearing plate 1. One end of the guide post 26 is connected to the bottom of the buffer groove 25. The sleeve 27 is slidably arranged at the other end of the guide post 26. The guide post 26 and the sleeve 27 are correspondingly provided in multiple numbers. The buffer plate 28 is connected to a plurality of sleeves 27 at the same time. The spring 29 is sleeved outside the sleeve 27 and the guide post 26, and both ends of the spring 29 are respectively connected to the bottom of the buffer groove 25 and the buffer plate 28.

[0063] The working principle and beneficial effects of the above technical solution are as follows:

[0064] A buffer assembly is provided on the positioning plate 21. When the rail transport vehicle 15 approaches the positioning plate 21, the side surface of the load-bearing plate 1 contacts the buffer plate 28, squeezes the buffer plate 28 into the buffer groove 25, and compresses the spring 29 until the buffer plate 28 completely moves into the buffer groove 25, and the rail transport vehicle 15 contacts the positioning plate 21; the sleeve 27 slides outside the guide post 26 to guide the buffer plate 28; under the action of the spring 29, when the rail transport vehicle 15 stops, the impact generated by the positioning plate 21 on it is reduced, and the parking stability of the rail transport vehicle 15 is improved.

[0066] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present creation of the utility model.
