[0031] In order to make the skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0032] The first aspect embodiment of the present application provides a steel coil transportation system, which improves the electricity pickup effect of the electricity pickup device and ensures the running stability of the transport vehicle.

[0033] The present application will be described below in conjunction with the drawings and with reference to specific embodiments: Please refer to Figure 1 and Figure 2The steel coil transportation system provided by the embodiments of the present application comprises a track assembly and a transportation vehicle 200. The track assembly is provided with two track assemblies, and the two track assemblies are cross arranged. The track assembly comprises two parallel tracks, the top surface of the track is flush with the ground, and a high-frequency cable is embedded in the ground. The transportation vehicle 200 runs on one of the track assemblies. The transportation vehicle 200 comprises a power pickup assembly 230, and the power pickup assembly 230 comprises a support 232 and a power pickup device 233. The power pickup device 233 is installed on the support 232, and is used to pick up power from the high-frequency cable. The power pickup device 233 is arranged in a spaced manner with the ground. The power pickup device 233 is provided with at least two power pickup devices 233, and the at least two power pickup devices 233 are arranged in a spaced manner along the running direction of the transportation vehicle 200.

[0034] There can be two track assemblies in the workshop. For example, one of the track assemblies is used for running the transportation vehicle 200 for transporting steel coils, and the other track assembly is also used for running the transportation vehicle 200 for transporting steel coils. That is, two transportation vehicles 200 run on two track assemblies respectively to realize the transportation of steel coils. Since the transportation directions of different steel coils can be different, the two track assemblies can be cross arranged. For example, the two track assemblies are perpendicular to each other, or the included angle between the two track assemblies is an acute angle. The specific cross direction can be determined according to the transportation demand.

[0035] The transportation vehicle 200 runs on the track assembly to realize the transportation of the steel coil. The power for the running of the transportation vehicle 200 comes from the driving member 241, for example, a motor. The power pickup assembly 230 of the transportation vehicle 200 can pick up the power of the high-frequency cable embedded in the ground. The driving member 241 is electrically connected with the power pickup device 233. That is, the power pickup device 233 picks up the power of the high-frequency cable in a non-contact manner, and then supplies the power to the driving member 241, so as to realize the continuous work of the driving member 241 and ensure the running of the transportation vehicle 200.

[0036] The high-frequency cable is embedded in the ground. At the position where the two tracks intersect, the high-frequency cable is located below the track of the other track assembly. When the power pickup device 233 moves to the track of the other track assembly, it cannot pick up the power of the high-frequency cable, which can cause the transportation vehicle 200 to lose the running power. The power pickup device 233 is provided with at least two power pickup devices 233, and the at least two power pickup devices 233 are arranged in a spaced manner along the running direction of the transportation vehicle 200. In this way, when one of the power pickup devices 233 runs above the track of the other track assembly, the other power pickup device 233 can be offset from the track of the other track assembly, so as to pick up the power of the high-frequency cable and ensure the running power of the transportation vehicle 200.

[0037] For the convenience of introduction, the two track assemblies are respectively named as a first track assembly 110 and a second track assembly 120. The two parallel tracks of the first track assembly 110 are called first tracks 111, and the two parallel tracks of the second track assembly 120 are called second tracks 121. The first tracks 111 and the second tracks 121 are perpendicular to each other.

[0038] Please refer to Figure 2 , the transport vehicle 200 comprises a vehicle body 210 and a walking wheel set 220, the walking wheel set 220 is installed on the vehicle body 210 and walks on the two first tracks 111. The walking wheel set 220 is provided with multiple groups, and the multiple groups of walking wheel sets 220 are sequentially arranged along the walking direction of the transport vehicle 200, so as to realize stable walking of the transport vehicle 200 and ensure the stability of the steel coil transportation.

[0039] Please continue to refer to Figure 2 In some embodiments, the walking wheel set 220 comprises two walking wheels 221 and a shaft coupling 222, and the two walking wheels 221 are connected through the shaft coupling 222. The rim 2211 of the walking wheel 221 protrudes radially from the body of the walking wheel 221 to form a flange. Generally, the flange is located on the side of the two walking wheels 221 of the walking wheel set 220 that are close to each other. Of course, in other embodiments, the flange can also be located on the side of the two walking wheels 221 of the walking wheel set 220 that are far from each other, and the present application does not make any limitation. In the following description, the flange is located on the inner side of the two walking wheels 221 that are close to each other as an example.

[0040] The setting of the flange can avoid the problem of derailment when the transport vehicle 200 turns. The flange is located on the side of the first track 111, so the ground and the first track 111 are not fully attached, and a groove accommodating the flange is formed between the ground and the first track 111. Similarly, the second track 121 also has a groove accommodating the flange between the ground and the second track 121.

[0041] Please refer to Figure 8 , Figure 9 and Figure 10 , the connecting part of the first track 111 and the second track 121 is provided with an avoiding groove 104 avoiding the flange 2211, and the avoiding groove 104 is provided through along the walking direction of the transport vehicle 200, that is, the connecting part of the first track 111 and the second track 121 is provided with an avoiding groove 104 avoiding the flange, so that the transport vehicle 200 can smoothly pass through the second track 121.

[0042] In some embodiments, the walking wheel set 220 is provided with multiple groups, and the multiple groups of walking wheel sets 220 are arranged at intervals along the walking direction of the transport vehicle 200, and the adjacent two walking wheel sets 220 are connected through a chain transmission mechanism.

[0043] The plurality of walking wheels 221 can improve the stability of the transport vehicle 200 during walking. Adjacent walking wheel groups 220 can be connected by a chain transmission mechanism. One driving member 241 can drive two walking wheel groups 220 to move, so as to realize the walking of the transport vehicle 200. For example, four walking wheel groups 220 are arranged in two groups, and two driving members 241 are arranged. Each driving member 241 drives two walking wheel groups 220 to realize the walking of the transport vehicle 200. Of course, one driving member 241 can be arranged for each walking wheel group 220, and each driving member 241 can drive the walking wheel group 220 independently to realize the walking of the transport vehicle 200.

[0044] In some embodiments, as shown in Figure 2 , the adjacent two walking wheel groups 220 are connected by a chain transmission mechanism. In the case that the second walking wheel 221 walks to the connection between the first track assembly 110 and the second track assembly 120, the rim 2211 is arranged to be spaced from the groove bottom of the avoidance groove 104. The adjacent two walking wheel groups 220 are connected by a chain transmission mechanism, so that the angular velocities of the walking wheels 221 of the two walking wheel groups 220 are the same, but the diameters of the rims 2211 are relatively large, so that the linear velocities of the rims 2211 are greater than the linear velocities of the walking wheels 221. The rim 2211 is arranged to be spaced from the groove bottom of the avoidance groove 104, so that the linear velocities of the adjacent two walking wheel groups 220 are consistent, and the chain is uniformly stressed. If the rim 2211 contacts the groove bottom of the avoidance groove 104, the linear velocities of the adjacent two walking wheel groups 220 can be inconsistent, and the chain can be taut.

[0045] In some embodiments, the groove width of the avoidance groove 104 gradually increases from the middle to both ends. The openings of the avoidance groove 104 on both sides in the walking direction of the transport vehicle 200 are relatively large, so that the rims 2211 of the walking wheel groups 220 can be guided to enter the avoidance groove 104, and the operation of the transport vehicle 200 is more stable. In other embodiments, the groove width of the avoidance groove 104 remains unchanged in the walking direction of the transport vehicle 200, so that a space for the rims 2211 to pass through can also be formed.

[0046] In some embodiments, as shown in Figure 8 to Figure 10 , the connection assembly 130 is arranged at the connection between the first track 111 and the second track 121, and the connection assembly 130 and the tracks jointly form the avoidance groove 104. The connection assembly 130 is arranged to make the installation of the tracks more convenient. In other embodiments, the connection between the first track 111 and the second track 121 can also be arranged as an integrated structure, and the installation of the track assembly can still be realized.

[0047] As shown in Figure 9, the first track 111 is provided with two, the second track 121 is provided with two, therefore the first track 111 and the second track 121 junction has four, the connecting assembly 130 is also provided with four, four connecting assembly 130 and four junctions one-to-one corresponding arrangement. In some embodiments, please refer to Figure 10 , the connecting assembly 130 includes support frame 134, first connecting piece 131 and second connecting piece 132, the first track 111 is disconnected, forming the interval for the second track 121 through, that is, the first track 111 has two track segments, two track segments are arranged at intervals, the second track 121 passes through the interval. The first connecting piece 131 and the second connecting piece 132 are located on both sides of the width direction of the second track 121 respectively, and the first connecting piece 131 and the second connecting piece 132 are located on the same side of the first track 111, the first connecting piece 131 is connected with one of the track segments and the support frame 134, the second connecting piece 132 is connected with the other track segment and the support frame 134, the second track 121 is connected with the support frame 134, the first connecting piece 131 and one of the track segments enclose the first avoiding groove 101, the second connecting piece 132 and the other track segment enclose the second avoiding groove 102, the second track 121 is provided with the third avoiding groove 103, so that the first track 111 and the second track 121 are connected at the disconnected part of the first track 111 through the support frame 134, the first connecting piece 131 and the second connecting piece 132, the first avoiding groove 101, the third avoiding groove 103 and the second avoiding groove 102 are sequentially communicated along the walking direction of the transport vehicle 200, and jointly constitute the avoiding groove 104 for the rim 2211 to pass through.

[0048] In some embodiments, please refer to Figure 11 , the first connecting piece 131 has a fitting surface matched with the side surface of the width direction of the first track 111, and the second connecting piece 132 also has a fitting surface matched with the side surface of the width direction of the first track 111, that is, the first connecting piece 131 and the second connecting piece 132 are both profiled according to the first track 111, and the first connecting piece 131 and the second connecting piece 132 can be fitted with the first track 111, closely and firmly, improving the installation stability of the first track 111.

[0049] The walking wheel set 220 of the transport vehicle 200 passing through the second track 121 is the same as the walking wheel set 220 of the transport vehicle 200 passing through the first track 111, therefore the second track 121 is similar to the first track 111, and also needs to be provided with the avoiding groove 104 for the rim 2211 of the walking wheel set 220 to pass through at the junction of the first track 111 and the second track 121. In some embodiments, please refer to Figure 10 , Figure 12 and Figure 13The connecting assembly 130 further comprises a third connecting piece 133, a middle portion of the third connecting piece 133 in the extension direction of the second track 121 is provided with a positioning gap 1331 for inserting the first track 111, two ends of the third connecting piece 133 in the extension direction of the second track 121 are respectively located on both sides of the first track 111 in the width direction, and the two ends of the third connecting piece 133 in the extension direction of the second track 121 are respectively connected with the second track 121. The third connecting piece 133, the first track 111 and the second track 121 jointly form an avoiding groove 104 for the gap of the rim 2211 to pass through.

[0050] For the electricity pickup assembly 230, it is a non-contact power supply device. According to the principle of electromagnetic induction, when the high-frequency cable embedded in the ground passes through high-frequency current, a magnetic field is generated around the high-frequency cable. The electricity taker 233 located above the ground generally includes coils, capacitors and other elements. After sensing the magnetic field around the high-frequency cable, an electric current is excited, which plays a role of electricity pickup, thereby providing energy for the transport vehicle 200.

[0051] In the width direction of the transport vehicle 200, the electricity pickup assembly 230 is arranged above the first track 111, and the high-frequency cable extends in parallel to the first track 111. Therefore, at the intersection of the first track 111 and the second track 121, the high-frequency cable is located below the second track 121, and the electromagnetic field generated by the high-frequency cable at the intersection is disturbed by the second track 121. In some embodiments, referring to Figure 5 The electricity taker 233 can be provided with two, which can realize uninterrupted electricity pickup and reduce equipment cost. Of course, in other embodiments, the electricity taker 233 can be provided with three, four or other numbers, and the present application does not make any limitation.

[0052] Taking the case that the electricity taker 233 is provided with two as an example, the two electricity takers 233 are respectively a first electricity taker and a second electricity taker. In the selection of the electricity taker 233, the peak power of a single electricity taker 233 is greater than the walking power of the transport vehicle 200, but the stable power of the electricity taker 233 is lower than the walking power of the transport vehicle 200. In this way, during the normal walking of the transport vehicle 200, the two electricity takers 233 work at the stable power at the same time, which can provide the walking power of the transport vehicle 200, and the electricity taker 233 is not easy to heat, thereby improving the service life of the electricity taker 233. Although the peak power of the electricity taker 233 is greater than the walking power of the transport vehicle 200, the single work can still ensure the normal walking of the transport vehicle 200, but the heat quantity is large, which will reduce the service life of the electricity taker 233.

[0053] In the present application, the dimension of the power taker 233 along the walking direction of the transport vehicle 200 and the dimension of the interval between the two power takers 233 are not less than the width of the second track 121, that is, in the case where the first power taker is above the second track 121, the projection of the second power taker in the vertical direction must fall outside the second track 121, so that the second power taker can take power from the high-frequency cable, further ensuring uninterrupted power supply of the transport vehicle 200. Since the peak power of the first power taker and the second power taker is greater than the walking power of the transport vehicle 200, in the case where the first power taker is above the second track 121, the second power taker can use the peak power to provide energy for the transport vehicle, ensuring the normal walking of the transport vehicle 200. The time for the first power taker to pass through the second track 121 is very short, and the peak power of the second power taker can be maintained for a certain period of time, for example, 15s, without causing overheating damage to the second power taker. Therefore, the cooperation of the two power takers 233 not only meets the energy demand of the transport vehicle 200, but also does not generate excessive heat, ensuring the service life of the power taker 233.

[0054] In some embodiments, the dimension of the power taker 233 along the walking direction of the transport vehicle 200 is less than the interval between the two second tracks 121, that is, the interval between the two second tracks 121 is greater than the length dimension of the power taker 233, so that during the process of the transport vehicle 200 passing through the second track assembly 120, the power taker 233 does not coincide with the two second tracks 121 at the same time, further ensuring that the power taker 233 takes power from the high-frequency cable and provides uninterrupted power supply to the transport vehicle 200.

[0055] In some embodiments, please refer to Figure 5 、 Figure 6 and Figure 7 The power pickup assembly 230 can include a support wheel set 231 mounted to the bracket 232, the support wheel set 231 being rollingly connected to the ground, the support wheel set 231 being provided in at least three sets, the at least three sets of support wheel sets 231 being spaced apart along the walking direction of the transport vehicle 200.

[0056] The power taker 233 needs to be arranged with an interval between the ground to achieve non-contact power taking, but may be scratched by the power taker 233 when encountering uneven ground. The support wheel set 231 is provided, and the support wheel set 231 is rollingly connected to the ground, so that even if encountering uneven ground, the support wheel set 231 can ensure that the power taker 233 does not contact the ground, and the power taker 233 is maintained.

[0057] Since the transport vehicle 200 will pass through the second track assembly 120 during the process of walking on the first track assembly 110, and there is a groove between the second track 121 and the ground, the supporting wheel group 231 will sink when passing through the groove, so at least three supporting wheel groups 231 are arranged to make the power pickup assembly 230 more stable, and ensure that the power pickup device 233 is always not in contact with the ground and the second track 121, thereby protecting the power pickup device 233.

[0058] When the supporting wheel group 231 is arranged, please refer to Figure 7 , the supporting wheel group 231 can be arranged between the two power pickup devices 233, and the supporting wheel group 231 can also be arranged on the two outer sides opposite to the two power pickup devices 233.

[0059] In some embodiments, please continue to refer to Figure 7 , the support 232 includes a mounting frame 2321 and an adjusting frame 2323, the mounting frame 2321 is mounted to the vehicle body 210, and the supporting wheel group 231 is mounted to the adjusting frame 2323. The adjusting frame 2323 is movably connected with the mounting frame 2321 to adjust the height of the adjusting frame 2323.

[0060] The bottom surface of the supporting wheel group 231 is lower than the power pickup device 233, so the supporting wheel group 231 is always in rolling contact with the ground, and the power pickup device 233 is kept at a certain distance from the ground. In the case of uneven ground, the adjusting frame 2323 can be adjusted in a small range relative to the mounting frame 2321 to drive the height of the power pickup device 233 to be adjusted, thereby ensuring that the power pickup device 233 stably takes power from the high-frequency cable to obtain electric energy.

[0061] In some embodiments, please refer to Figure 7 , the support 232 can also include a rotating arm 2322, and the two ends of the rotating arm 2322 in the height direction are respectively hinged to the mounting frame 2321 and the adjusting frame 2323 through hinge shafts, and the hinge shafts extend horizontally. Through the hinged connection between the rotating arm 2322, the mounting frame 2321 and the adjusting frame 2323, the movable connection between the adjusting frame 2323 and the mounting frame 2321 is realized. In other embodiments, the support 232 can also be connected with the adjusting frame 2323 through a shock-absorbing cylinder, and the movable connection between the adjusting frame 2323 and the mounting frame 2321 can also be realized.

[0062] Please refer to Figure 9 , the vehicle body 210 of the transport vehicle 200 can be provided with a plurality of avoiding openings 211 for avoiding the winding trolley, so as to facilitate the winding and unwinding of the winding trolley for the transport vehicle 200. The vehicle body 210 is also provided with a support structure, and the number of the support structure is the same as that of the avoiding openings 211 and corresponds one by one. The support structure includes two saddle blocks 242 located on the two sides of the avoiding openings 211 along the length direction of the vehicle body 210, so that the steel rolls are supported by the saddle blocks 242 at the same time.

[0063] Each of the escape ports 211 can correspond to four saddle blocks 242, two on each side, and the two saddle blocks 242 are sequentially arranged along the width direction of the vehicle body 210. The two sides of the vehicle body 210 located on the escape ports 211 along the walking direction of the transport vehicle 200 can be provided as inclined surfaces, and the height of the inclined surfaces close to each other is lower than the height of the side far away, that is, in a V shape, and the saddle blocks 242 are installed on the inclined surfaces. When the steel coil is placed, the axial direction of the steel coil is perpendicular to the running direction of the transport vehicle 200, and the V-shaped structure design improves the stability of the steel coil transportation process. The saddle blocks 242 can be made of nylon or polyurethane, which can protect the surface of the steel coil.

[0064] The two ends of the first track 111 respectively extend to the coil unloading bay and the coil loading bay, and the first track 111 located on the same side of the escape port 211 is provided with two discontinuities 1111, and the two discontinuities 1111 are located in the coil unloading bay and the coil loading bay respectively. The discontinuity 1111 is used for the passage of the steel coil trolley, so that the steel coil can be transferred to the support structure by the steel coil trolley in the coil loading bay without being lifted by the crown block. After being transported to the coil unloading bay, the steel coil on the transport vehicle 200 can be unloaded by the steel coil trolley. The whole process does not need the crown block to participate, reduces the risk of steel coil collision, and improves the quality of the steel coil.

[0065] Specifically, when one of the escape ports 211 of the transport vehicle 200 reaches the coil unloading position, the escape port 211 corresponds in position to the discontinuity 1111 of the coil unloading bay, so that the steel coil trolley can unload the steel coil. When one of the escape ports 211 of the transport vehicle 200 reaches the coil loading position, the escape port 211 corresponds in position to the discontinuity 1111 of the coil loading bay, so that the steel coil trolley can load the steel coil at this position.

[0066] The vehicle body 210 can be welded from section steel and steel plate.

[0067] The walking wheel set 220 is provided in multiple groups, and the multiple groups of walking wheel sets 220 are arranged at intervals along the walking direction of the transport vehicle 200. The interval between any two adjacent groups of walking wheel sets 220 is greater than the length of the discontinuity 1111, so that when the transport vehicle 200 passes through the discontinuity 1111 of the first track 111, at most one walking wheel 221 is suspended, the stress of the vehicle body 210 is balanced, and the running stability of the transport vehicle 200 is ensured.

[0068] The vehicle body 210 is provided with a driving member 241, such as a speed reducer, and the walking wheel set 220 is provided with a sprocket 223 coaxial with the shaft coupling 222. The driving member 241 is in transmission connection with one of the walking wheel sets 220, and the sprockets 223 of the adjacent walking wheel sets 220 are in meshing connection with the closed chain, so as to realize power transmission. The chain transmission can realize that one power member transmits torque to multiple groups of walking wheel sets 220, and the equipment is simpler and occupies less space.

[0069] Please refer to Figure 4 , the transport vehicle 200 further comprises a control cabinet 250 installed on the vehicle body 210, and a controller in the control cabinet 250 is electrically connected with the driving member 241 to realize receiving and sending instructions. The transport vehicle 200 can further comprise a guardrail surrounding the control cabinet 250 to provide protection for the controller. The guardrail can be obtained by welding steel pipes and steel plates.

[0070] The transport vehicle 200 further comprises a tracking assembly, please refer to Figure 2 , the tracking assembly comprises an RFID reader 263 and a mounting bracket, the mounting bracket is fixed on the front end or the rear end of the vehicle body 210 by bolts, facilitating installation and maintenance, and tracking the real-time position of the transport vehicle 200.

[0071] The transport vehicle 200 further comprises a positioning assembly, please refer to Figure 1 and Figure 4 , the positioning assembly comprises a displacement sensor 261 and a detection reference 262, the displacement sensor 261 is installed on the vehicle body 210, and the detection reference 262 is installed on the ground. The displacement sensor 261 is electrically connected with the controller, the displacement sensor 261 can detect the distance between itself and the detection reference 262 and transmit a signal to the controller, and the controller can determine whether the transport vehicle 200 reaches a target position, such as whether it reaches a coiling position or an uncoiling position, according to the distance between the vehicle body 210 and the detection reference 262. In specific implementation, the detection reference 262 can be arranged in both the coiling and uncoiling bays, and the precise position of the transport vehicle 200 can be determined by displacement, so that the transport vehicle 200 can be automatically stopped at the coiling and uncoiling positions, and the degree of automation is high. The displacement sensor 261 can be a laser range finder or other displacement sensor 261, which is not limited in the present application.

[0072] The vehicle body 210 can further be provided with a pressure sensor (not shown in the figure), which is electrically connected with the controller. The pressure sensor can transmit a pressure signal to the controller. When there is a steel coil on the saddle block 242, the pressure detected by the pressure sensor is large, and the controller will determine that there is a steel coil on the saddle block 242. When there is no steel coil on the saddle block 242, the pressure detected by the pressure sensor is zero, and the controller will determine that there is no steel coil on the saddle block 242. That is, the pressure sensor can detect whether there is a steel coil on the saddle block 242, which is convenient for determining whether the coiling or uncoiling is successful.

[0073] Please refer to Figure 4 , the vehicle body 210 is further provided with a radar 264 to ensure the safety of the forward and backward directions of the transport vehicle 200. When the forward direction is blocked by an obstacle, the radar 264 will transmit a signal to the controller, and the controller will control the driving member 241 to stop working to avoid collision with the obstacle.

[0074] If there are conductive impurities on the ground, the electromagnetic field around the high-frequency cable can be affected, reducing the electromagnetic coupling efficiency and thus reducing the power obtained by the power extractor 233. Therefore, in some embodiments, the vehicle body 210 can also be provided with a cleaning brush (not shown in the figure) to clean the ground. The conductive impurities on the ground are cleaned during the movement of the transport vehicle 200, improving the power extraction effect of the power extractor 233.

When the transport vehicle 200 passes through the cross track, the power pickup assembly 230 can smoothly pass through the break 1111 of the track and will not cause the power extractor 233 to knock against the track.

[0076] (2) The power extractor 233 is provided with multiple power extractors. Even when passing through the cross track, at least one power extractor 233 can be ensured to be electromagnetically coupled with the high-frequency cable at all times, ensuring the power extraction efficiency of the power extractor 233 and the running stability of the transport vehicle 200.

[0077] (3) The power pickup assembly 230 is provided with multiple sets of support wheel groups 231, so that the power extractor 233 will not knock against the second track 121 when the transport vehicle 200 passes through the cross track, further improving the running stability of the transport vehicle 200.

[0078] (4) The two track assemblies intersect to form a cross track, and the intersection is provided with an avoidance slot 104. The rim 2211 of the walking wheel 221 is arranged at an interval from the slot bottom of the avoidance slot 104, improving the stability of the chain wheel 223 transmission.

[0079] (5) The height of the vehicle body 210 is low, which can reduce the lifting stroke of the steel coil trolley when the coil is taken off or placed on the transport vehicle 200, saving energy consumption.

[0080] (6) One side of the vehicle body 210 has multiple avoidance openings 211, which facilitate the loading or unloading of the steel coil trolley. The distance between the walking wheels 221 on the side of the avoidance opening 211 is greater than the length of the break 1111 of the first track 111, so that at most one walking wheel 221 is suspended when passing through the break 1111, and the running stability of the vehicle body 210 is high.

[0081] (7) The transport vehicle 200 has a positioning assembly, a steel coil detection and tracking assembly, and a radar 264, etc., realizing precise positioning and the signal of whether the saddle seat has a coil, and having high automation degree.
