[0025] In some embodiments, the object-carrying platform 20 can include: a platform base 210, the bottom of the platform base 210 being fixedly arranged on the top of the transport vehicle body 10; a first slope structure 220 arranged on the first side of the top of the platform base 210; a second slope structure 230 arranged on the second side of the top of the platform base 210; wherein the first side of the top of the platform base 210 is opposite to the second side of the top of the platform base 210, the slope surface of the first slope structure 220 is opposite to the slope surface of the second slope structure 230, a groove 240 is arranged between the first slope structure 220 and the second slope structure 230, and the concave carrying surface includes the slope surface of the first slope structure 220, the slope surface of the second slope structure 230 and the surface of the groove 240.

[0026] Specifically, the height of the slope surface of the first slope structure 220 gradually decreases from the first side of the top of the platform base 210 to the central position of the top of the platform base 210, and the height of the slope surface of the second slope structure 230 gradually decreases from the second side of the top of the platform base 210 to the central position of the top of the platform base 210. By arranging the first slope structure 220 and the second slope structure 230, the movement of the steel coil can be restricted to some extent, so that the inclination angle of the steel coil is prevented from being too large, and the possibility of the steel coil being rolled over is reduced.

[0027] It should be noted that in the concave bearing surface, the slope surface of the first slope structure 220 and the slope surface of the second slope structure 230 are in contact with the steel coil, and the surface of the groove 240 can be in contact with the steel coil or not. The groove 240 can be mainly used for installing a range finder. The extension direction of the groove 240 is parallel to the first side of the top of the platform base 210. The groove 240 can be a solid structure arranged between the first slope structure 220 and the second slope structure 230, or a non-solid structure formed by the gap between the first slope structure 220 and the second slope structure 230.

[0028] In some embodiments, the first range finder 30 is located at the first end of the groove 240, and the second range finder 40 is located at the second end of the groove 240. The first end of the groove 240 and the second end of the groove 240 are the two ends in the extension direction of the groove 240.

[0029] Reference Figure 2 shown, Figure 2 is a schematic view of the installation position of the range finder on the object carrying platform in the embodiment of the utility model, wherein, Figure 2 (a) is an oblique view of the object carrying platform, Figure 2 (b) is a top view of the object carrying platform. It should be noted that the extension direction of the groove 240 can be parallel to the movement direction of the steel coil transport vehicle.

[0030] In some embodiments, the steel coil transport vehicle can further include: a third range finder 50 arranged on the groove 240 and close to the first end of the groove 240; and a fourth range finder 60 arranged on the groove 240 and close to the second end of the groove 240. The ranging direction of the third range finder 50 and the fourth range finder 60 is perpendicular to the horizontal plane on which the object carrying platform 20 is located, and the controller is electrically connected to the third range finder 50 and the fourth range finder 60, respectively.

[0031] Reference Figure 2As shown, since the first distance meter 30, the second distance meter 40, the third distance meter 50 and the fourth distance meter 60 are all arranged on the groove 240, the distance deviation of the detection distance of the first distance meter 30 and the detection distance of the second distance meter 40 can represent the inclination degree of the steel coil, and the distance deviation of the detection distance of the third distance meter 50 and the detection distance of the fourth distance meter 60 can also represent the inclination degree of the steel coil. Therefore, the first distance meter 30 and the second distance meter 40 can be selected, or the third distance meter 50 and the fourth distance meter 60 can be selected to judge the inclination degree of the steel coil. Since the distance between the first distance meter 30 and the second distance meter 40 is greater than the distance between the third distance meter 50 and the fourth distance meter 60, the specific selection method can be determined according to the width of the steel coil. For example, if the width of the steel coil is greater than the distance between the first distance meter 30 and the second distance meter 40, the first distance meter 30 and the second distance meter 40 can be selected to judge the inclination degree of the steel coil. If the width of the steel coil is less than the distance between the first distance meter 30 and the second distance meter 40, the steel coil can be placed between the first distance meter 30 and the second distance meter 40, so that the first distance meter 30 and the second distance meter 40 cannot detect the steel coil. Therefore, only the third distance meter 50 and the fourth distance meter 60 can be selected to judge the inclination degree of the steel coil. Therefore, the accuracy of detecting the inclination degree of the steel coil is improved.

[0032] In some embodiments, the steel coil transport vehicle can further comprise: a fifth distance meter 70 arranged on the slope surface of the first slope structure 220; and a sixth distance meter 80 arranged on the slope surface of the second slope structure 230, wherein the distance measuring direction of the fifth distance meter 70 and the sixth distance meter 80 is perpendicular to the horizontal plane on which the object carrying platform 20 is located, the controller is electrically connected with the fifth distance meter 70 and the sixth distance meter 80 respectively, and the straight line on which the fifth distance meter 70 and the sixth distance meter 80 are located is perpendicular to the extension direction of the groove 240.

[0033] In some embodiments, the distance between the fifth distance meter 70 and the groove 240 is equal to the distance between the sixth distance meter 80 and the groove 240, the fifth distance meter 70 is located at the position with the maximum slope surface height on the slope surface of the first slope structure 220, and the sixth distance meter 80 is located at the position with the maximum slope surface height on the slope surface of the second slope structure 230.

[0034] Reference Figure 3 and Figure 4 As shown, Figure 3 Fig. 1 is a schematic view of a steel coil in the x-axis direction according to an embodiment of the present application, and specifically, Figure 3 (a) is a schematic view of a steel coil in the x-axis direction without inclination under a first perspective, Figure 3 (b) is a schematic view of a steel coil in the x-axis direction with inclination under the first perspective; Figure 4A schematic view of the steel coil in the y-axis direction in the embodiment of the utility model, Figure 4 (a) is a schematic view of the steel coil in the y-axis direction not inclined under the second perspective, Figure 4 (b) is a schematic view of the steel coil in the y-axis direction inclined under the second perspective; assuming that the extension direction of the groove 240 is the x-axis direction, the direction perpendicular to the extension direction of the groove 240 and parallel to the horizontal plane where the object platform 20 is located is the y-axis direction, then the first distance meter 30 and the second distance meter 40 realize the detection of the inclination degree of the steel coil in the x-axis direction, the fifth distance meter 70 and the sixth distance meter 80 realize the detection of the inclination degree of the steel coil in the y-axis direction, so that the inclination degree of the steel coil is detected in multiple directions, and the accuracy of the inclination degree detection of the steel coil is improved.

[0035] In some embodiments, the fifth distance meter 70 and the sixth distance meter 80 are located on the symmetry plane of the groove 240, and the symmetry plane of the groove 240 refers to the symmetry plane perpendicular to the extension direction of the groove 240.

[0036] It should be noted that the fifth distance meter 70 and the sixth distance meter 80 are located on the symmetry plane of the groove 240, that is, the fifth distance meter 70 and the sixth distance meter 80 are located at the center position of the concave bearing surface, in this case, the fifth distance meter 70 and the sixth distance meter 80 can conveniently detect the inclination degree of the steel coil, and the situation that the fifth distance meter 70 and the sixth distance meter 80 are located at the edge position of the concave bearing surface and the steel coil is not detected is avoided. Therefore, the accuracy of the inclination degree detection of the steel coil is improved.

[0037] In some embodiments, the first distance meter 30, the second distance meter 40, the third distance meter 50, the fourth distance meter 60, the fifth distance meter 70 and the sixth distance meter 80 can be laser distance meters, and the laser emission direction of the laser distance meter is perpendicular to the horizontal plane where the object platform 20 is located.

[0038] In some embodiments, the transport vehicle body 10 can include: a vehicle body base 110; a wheel 120 arranged at the bottom of the vehicle body base 110; a hydraulic elevator 130, the bottom fixed end of the hydraulic elevator 130 is arranged at the top of the vehicle body base 110, and the bottom of the object platform 20 is fixedly arranged at the top moving end of the hydraulic elevator 130.

[0039] Reference Figure 5 As shown, Figure 5 It is a schematic view of the position relationship between the steel coil transport vehicle and the steel coil in the embodiment of the utility model.

[0040] It should be noted that the transport vehicle body 10 further includes a motor for providing power. The hydraulic elevator 130 is electrically connected with the controller.

[0041] In some embodiments, the steel coil transport vehicle can further comprise an alarm electrically connected to the controller.

[0042] It should be noted that the alarm can be installed on the groove 240, or on the side of the object carrying platform 20, etc. The alarm can be an audible and visual alarm. When the inclination of the steel coil is detected to be too large, the controller can control the alarm to alarm to prompt the staff to intervene, thereby improving the safety of the steel coil transportation.

[0043] It should be noted that in a continuously running steel coil production line, the steel coil transport vehicle is responsible for the transportation of the steel coil. The steel coil transport vehicle at the entrance section lifts the steel coil from the saddle and transports it to the ground roller, during which the width is measured, then the diameter is centered, and then the steel coil is smoothly transported to the decoiler spindle for decoiling. The steel coil transport vehicle at the exit section is responsible for unloading the steel coil produced by the coiling machine from the coiling machine spindle, transporting it to the weighing saddle for weighing, and then transporting it to the stepping bar. The position of the steel coil transport vehicle can be determined by the steel coil transport vehicle rotary encoder. However, in actual production, due to abnormality of the width and diameter measuring gratings and interference of complex environmental factors on site, there are reasons such as slippage of the steel coil transport vehicle wheels 120 and the track, which can cause deviation of the steel coil transport vehicle from the centering position of the steel coil, resulting in a rollover accident. The reasons for the rollover are as follows: first, the detection device is abnormal, which can cause the rollover. For example, abnormality of the width measuring device can cause the center line of the steel coil transport vehicle to deviate too much from the center line of the steel coil, and the trolley can tip over when lifting the steel coil from the saddle or the ground roller. In addition, abnormality of the outer diameter measuring device can cause the inner circle of the steel coil on the steel coil transport vehicle to fail to align with the decoiler spindle, and the steel coil can be tipped over by the spindle. Second, the on-site equipment and the position of the steel coil are unreasonable. Specifically, the steel coil transport vehicle can collide with the equipment during the transportation of the steel coil, which can cause the steel coil to tilt. Foreign matter on the saddle or the ground roller can also cause the steel coil to tilt and roll over when the steel coil is lifted or lowered. When the steel coil is lifted to the saddle, the center position of the steel coil and the steel coil transport vehicle deviates too much, and the trolley can tip over the steel coil when the trolley is lifted on the saddle. Therefore, during normal production, the operator needs to keep an eye on the state of the steel coil at all times, and once the steel coil is found to be tilted, the action of the steel coil transport vehicle should be stopped immediately. The dependence on manual protection is too high, which is not conducive to effectively ensuring the safety of the operation, and with the development of automated factories and the construction of unmanned workshops, the safety of the operators also needs to be considered, and the self-driving intelligent protection of the transportation needs to be implemented. The embodiments of the present application can reduce the rollover probability during steel coil transportation, can continuously monitor the position and inclination angle of the steel coil on the steel coil transport vehicle in real time, and can increase the timeliness and safety of the intelligent interlocking protection during the transportation process.

[0044] It should be noted that when the steel coil exceeds the width boundary value L, the output results of the first distance meter 30 and the second distance meter 40 can be applied; when the steel coil is below the width boundary value L, the output results of the third distance meter 50 and the fourth distance meter 60 are applied. The priority of the distance measurement results of the first distance meter 30 and the second distance meter 40 is higher than the priority of the distance measurement results of the third distance meter 50 and the fourth distance meter 60. The laser distance meter can be a diffuse reflection laser distance meter.

[0045] The control method of the steel coil transport vehicle in the embodiment of the utility model will be described below. It is assumed that the second distance meter 40 is located at the head position of the steel coil transport vehicle. The method comprises the following steps S1-S5:

[0046] S1, when the controller receives the automatic coil loading execution program sent by the production line operation table, the first step only triggers the second distance meter 40, that is, starts distance measurement. At this time, the steel coil transport vehicle starts to move and approaches the steel coil on the saddle.

[0047] S2, when the steel coil transport vehicle moves to the position below the steel coil, the second distance meter 40 detects the steel coil and starts timing. Until the second distance meter 40 cannot detect the steel coil, the timing time is output. According to the timing time and the vehicle speed, the width of the steel coil can be determined, and the position of the steel coil on the saddle can be determined.

[0048] S3, the position of the steel coil transport vehicle is automatically adjusted according to the position of the steel coil on the saddle. When the steel coil transport vehicle moves directly below the steel coil, that is, the center line of the steel coil transport vehicle and the center line of the steel coil coincide, the steel coil is placed on the steel coil transport vehicle, and all distance meters are triggered to start distance measurement.

[0049] S4, during the lifting, lowering, advancing and retreating of the steel coil transport vehicle, the difference y12 between the value measured by the fifth distance meter 70 and the value measured by the sixth distance meter 80 can be converted into the inclination degree of the steel coil in the y-axis direction; when the steel coil exceeds the width boundary value L, the difference x14 between the value measured by the first distance meter 30 and the value measured by the second distance meter 40 can be converted into the inclination degree of the steel coil in the x-axis direction; when the steel coil does not exceed the width boundary value L, the difference x23 between the value measured by the third distance meter 50 and the value measured by the fourth distance meter 60 can be converted into the inclination degree of the steel coil in the x-axis direction.

[0050] S5, further, in step S4, the process can determine in real time whether the inclination of the steel coil exceeds a safety value. If any one of y12 and x14 (x23) exceeds the safety value, for example, 3mm, it indicates that the position or angle of the steel coil is abnormal and in a dangerous state of rolling over. At this time, the steel coil transport vehicle stops moving, and an alarm program is started to prompt the staff to pay attention.

[0051] It should be noted that the utility model embodiment is applicable to the transportation process of coiling-in trolley, coiling-out trolley and walking beam, contains the transportation device of heavy goods such as steel coil, wide use range, simple logic, high reliability, good stability. Can make the transport car reduce the coiling probability when first contacting heavy goods such as steel coil. Protects and restricts on the control of the transportation process, reacts quickly, can effectively reduce the occurrence of human error.

[0052] The utility model embodiment provides a kind of steel coil transport car, comprising: transport car body 10;Object platform 20, the bottom of object platform 20 is fixedly arranged on the top of transport car body 10;First range finder 30 and second range finder 40, are arranged in the different positions of the bottom of the concave load surface of object platform 20, and the ranging direction of first range finder 30 and second range finder 40 is all the direction perpendicular to the horizontal plane where object platform 20 is;Controller, with transport car body 10, first range finder 30 and second range finder 40 electric connection.When steel coil is placed on object platform 20, the detection distance of first range finder 30 is the distance between steel coil and first range finder 30, and the detection distance of second range finder 40 is the distance between steel coil and second range finder 40, and since first range finder 30 and second range finder 40 are arranged in the different positions of the bottom of the concave load surface, so the distance deviation of the detection distance of first range finder 30 and the detection distance of second range finder 40 can represent the inclination degree of steel coil.In the case that the inclination degree of steel coil is relatively large, the steel coil transport car is controlled to stop moving by controller, to avoid the inclination degree of steel coil continue to increase, so that the coiling accident of steel coil is avoided. Therefore, the transportation safety of steel coil is improved.
