TECHNICAL FIELD
[0001] The present application relates to the technical field of steel coil transportation, in particular to a cold-rolled strip steel coil overpass transportation device. BACKGROUND
[0002] The overpass car, also known as a trolley or an electric flatcar, is an electric rail factory transportation vehicle, mainly used for heavy goods transportation in factories and warehouses. It has the advantages of simple structure, easy use, easy maintenance, strong heavy load capacity, stable operation, and less pollution. Its power system includes single-phase or three-phase AC motor, which is powered by track or battery, and supports on-board handle line control or remote control operation. This device belongs to the category of industrial transportation equipment and is used for transporting heavy objects in the workshop in cooperation with the crane. It is applied downstream in mechanical manufacturing, metallurgical plants, etc. In addition, there is also a trackless electric flatcar, which uses polyurethane rubber-coated wheels and does not require track laying. It can straighten, turn, and has higher flexibility, suitable for flexible transportation scenarios in workshops and factories.
[0003] However, in actual use, we found that the existing trackless overpass car has the problem that when transporting cold-rolled strip steel coils, the existing overpass car usually adopts a rigid bearing structure to ensure its running stability. The V-shaped frame of this rigid structure usually has a fixed angle and cannot be adjusted to adapt to different diameters of steel coils, which leads to problems such as unstable clamping or local stress concentration when transporting different specifications of steel coils, affecting the transportation safety and the surface quality of the steel coils. If a small-diameter steel coil is encountered, the V-shaped frame angle may be too large, causing the steel coil to shake or even slip during transportation. On the other hand, a large-diameter steel coil may cause stress concentration on the contact surface due to the small angle, causing surface indentation or deformation. Therefore, we propose a cold-rolled strip steel coil overpass transportation device. SUMMARY

[0045] The grading assembly 7 comprises a filler 11 arranged on the first frame plate 4, which is used to fill the distance between the first frame plate 4 and the two clamping plates 3, and a trigger 12 arranged on the first frame plate 4, which is used to drive the two lifting plates 101 to split, and an aggregation piece 13 arranged above the cross car body 1, which is used to drive the two lifting plates 101 and the threaded grooves 102 arranged in the two lifting plates 101 to close.
[0046] The filler 11 comprises two filler plates 111 arranged above the two sides of the first frame plate 4, respectively, and the two filler plates 111 are both arc-shaped and are attached to the top of the first frame plate 4, and the opposite sides of the two filler plates 111 have a smaller thickness than the sides away from them, and are gradually thinned in an arc shape, and each of the two filler plates 111 is provided with a filler shaft 112, and the two filler shafts 112 are located on the opposite sides of the two filler plates 111, and each end of the two filler shafts 112 is rotatably provided with an auxiliary plate 113, and the four auxiliary plates 113 are rotatably arranged in the first frame plate 4 through the rotating shafts, and if the diameter of the steel roll body 2 is larger, the screw rod 91 needs to be continuously driven to rotate, at this time, since the first frame plate 4 has contacted the clamping plate 3 and is limited by the reaction force of the clamping plate 3 and the steel roll body 2, it will not continue to rise, and with the continuous rotation of the screw rod 91, the filler plate 111 located between the clamping plate 3 and the first frame plate 4 will be gradually rotated by the upward thrust of the first frame plate 4 and will be completely inserted between the clamping plate 3 and the first frame plate 4, and since the arc surface of the filler plate 111 has a high degree of attachment to the outer wall of the steel roll body 2, it can further enhance the wrapping and friction of the clamping after being inserted, and through the thickness deviation design, it realizes self-adaptive adjustment during the insertion process, effectively compensates the gap between the clamping plate 3 and the first frame plate 4, ensures the close contact between the clamping plate 3, the first frame plate 4 and the steel roll body 2 without gaps, thereby improving the reliability and safety of clamping, and when the filler plate 111 is rotated, the filler plate 111 will move downward together with the filler shaft 112 inside it, and the auxiliary plates 113 at both ends of the filler shaft 112 can guide and stabilize the movement of the filler shaft 112, preventing the filler shaft 112 from deflecting or jamming during movement, and its role is to enable the filler plate 111 to realize self-adjusting attachment according to the change in the outer diameter of the steel roll body 2 during the insertion process through the design of the filler plate 111 and the thickness difference of its arc surface, ensuring that the clamping plate 3 can maintain stable contact and uniform stress during clamping of steel roll bodies 2 of different specifications, and at the same time, with the stable support of the auxiliary plate 113 to the filler shaft 112, it ensures that the entire filling process is smooth and smooth, avoiding structural damage caused by eccentricity or uneven stress.

[0048] The polymerization member 13 comprises polymerization frames 131 arranged at the bottom of both ends of the first frame plate 4, polymerization springs 132 arranged at the top of the two polymerization frames 131, polymerization plates 133 arranged at the top of the two polymerization springs 132 and used in cooperation with the two lifting plates 101, four vertical plates 122 arranged at one end away from the four trigger plates 121 on the adjacent two polymerization plates 133, two sliding grooves 134 opened at the bottom of the first frame plate 4, and the two polymerization plates 133 slidingly arranged in the corresponding sliding grooves 134, the bottom of the two lifting plates 101 being inclined, two polymerization grooves 135 opened in the two polymerization plates 133 and used in cooperation with the two lifting plates 101, the top of the two polymerization grooves 135 being inclined, eight tension springs 136 arranged in the two sliding grooves 134 and corresponding to the eight equal parts divided by the two lifting plates 101, in the process of slow rotation of the filling plate 111, the filling shaft 112 moves reversely, the trigger plate 121 resets and drives the vertical plate 122 to rise, at this time, the polymerization spring 132 pushes the polymerization plate 133 to move upward, so that it slides in the sliding groove 134 and gradually passes through the polymerization groove 135 to reapply the guiding constraint to the inclined surface at the bottom of the lifting plate 101, so as to make the four equal parts divided by the lifting plate 101 re-polymerize, the lifting plate 101 slides along the limiting groove 104 under the guidance of the polymerization groove 135 and gradually closes, until completely resets, at this time, the tension spring 136 restores the initial tension, and prepares for the next clamping action; along with the re-polymerization of the lifting plate 101, the screw groove 102 in the lifting plate 101 rethreads with the screw rod 91, the screw rod 91 gradually establishes stable engagement with the lifting plate 101 in the process of continuing rotation, restores the power transmission path, so as to drive the lifting plate 101 to synchronously descend as a whole, in the process of descending of the lifting plate 101, the first frame plate 4 adhering to the top of the lifting plate 101 will move downward, so that the first frame plate 4 and the second frame plate 5 jointly descend, until completely resets, in this process, the clamping plate 3 gradually escapes from the limitation of the first frame plate 4 and the second frame plate 5, and naturally opens under the action of gravity, after the clamping plate 3 completely opens, the staff can smoothly take down the steel roll body 2, which serves to automatically restore the power chain and orderly reset the clamping plate 3 through the polymerization of the lifting plate 101 and the re-engagement of the screw rod 91, so as to ensure that the equipment can automatically release the locked state and restore to the initial standby position after completing a clamping operation, provides reliable guarantee for the installation and fixation of the next round of steel roll body 2, and improves the safety and efficiency of the overall operation.
[0049] In use, when the staff needs to use the cross car body 1 to transfer the steel roll body 2, first place the steel roll body 2 between the two clamping plates 3, in the initial state, the two clamping plates 3 are in the open state, after the steel roll body 2 is placed therebetween, start the double shaft extension motor 81, at this time, the double shaft extension motor 81 will drive the two drive shafts 82 at its ends to rotate synchronously, when the drive shaft 82 rotates, the drive bevel gears 83 arranged at the opposite ends of the two drive shafts 82 will rotate with the drive shaft 82, when the drive bevel gears 83 rotate, the transmission bevel gears 92 engaged with them will rotate, when the two transmission bevel gears 92 rotate, the two transmission bevel gears 92 will drive the screw rods 91 arranged at their respective shaft centers to rotate in the cross car body 1, when the screw rod 91 rotates, the second frame plate 5 threadedly connected with the screw rod 91 will move along the axial direction of the screw rod 91, thereby driving the second frame plate 5 to move upward, in the initial state, the lifting plate 101 is in the closed state under the action of the aggregation plate 133 and the aggregation groove 135, as the screw rod 91 rotates, the lifting plate 101 gradually rises by cooperating with the screw rod 91 through the threaded groove 102 in the lifting plate 101, in the process of the lifting plate 101 rising, the lifting plate 101 pushes the first frame plate 4 to move upward, thereby making the first frame plate 4 and the second frame plate 5 move upward synchronously, and then pushing the two clamping plates 3 to rotate in the cross car body 1 through the cooperation of the first frame plate 4 and the second frame plate 5, as the first frame plate 4 and the second frame plate 5 rise, the two clamping plates 3 slowly clamp the steel roll body 2, until completely fit and fix, if the steel roll body 2 is small in diameter, and the first frame plate 4 and the second frame plate 5 are located at the axial position of the steel roll body 2, it is not necessary to continue to drive the first frame plate 4 and the second frame plate 5 to rise, at this time, the function of the first frame plate 4 is to guide and stabilize the clamping process of the two clamping plates 3, to ensure that the clamping force is uniform, and to avoid deformation or falling of the steel roll due to unbalanced load, and the function of the second frame plate 5 is to reinforce and support the peripheral structure of the first frame plate 4, to ensure the stability and rigidity of the whole clamping system;
[0050] If the steel coil body 2 is larger in diameter, the screw 91 needs to continue to be driven to rotate. At this time, since the first frame plate 4 has been in contact with the clamping plate 3 and is limited by the reaction force of the clamping plate 3 and the steel coil body 2, it no longer continues to rise. With the continuous rotation of the screw 91, the filler plate 111 located between the clamping plate 3 and the first frame plate 4 will be gradually rotated by the upward thrust of the first frame plate 4 and completely inserted between the clamping plate 3 and the first frame plate 4. Since the arc surface of the filler plate 111 has high adhesion to the outer wall of the steel coil body 2, it can further enhance the wrapping and friction of clamping after insertion. And through the thickness deviation design, it realizes self-adaptive adjustment in the insertion process, effectively compensates the gap between the clamping plate 3 and the first frame plate 4, ensures the close contact between the clamping plate 3, the first frame plate 4 and the steel coil body 2 without gap, thereby improving the reliability and safety of clamping. When the filler plate 111 rotates, the filler shaft 112 inside the filler plate 111 will also move downward, and the auxiliary plate 113 at both ends of the filler shaft 112 can guide and stabilize the movement of the filler shaft 112, preventing the filler shaft 112 from deviating or jamming during movement. When the filler shaft 112 moves obliquely downward, the trigger plate 121 arranged at both ends of the filler shaft 112 will be displaced, thereby pushing the upright plate 122 at the other end of the trigger plate 121 to move downward, thereby transmitting the rotating force of the filler plate 111 to the polymerization plate 133 at the bottom of the upright plate 122. When the polymerization plate 133 is subjected to the downward pressure transmitted by the upright plate 122, the polymerization plate 133 will slide downward in the sliding groove 134, thereby causing the polymerization groove 135 in the polymerization plate 133 to gradually disengage from the cooperation with the lifting plate 101. At the moment when the polymerization plate 133 disengages from the limit, the lifting plate 101 loses the constraint and immediately separates rapidly under the action of the tension spring 136, and slides in the limiting groove 104 of the respective limiting plate 103 through the respective top limiting plate 103, completing the rapid disengagement action. The rapid separation of the lifting plate 101 causes the connection between the screw 91 and the lifting plate 101 to be decoupled instantaneously, and the screw 91 continues to rotate without driving the lifting plate 101 to rise, realizing automatic cut-off of power transmission, effectively avoiding damage to the clamping plate 3 and the steel coil body 2 caused by excessive lifting. With the continuous rotation of the screw 91, the second frame plate 5 continues to rise under the drive of the screw 91 and gradually disengages from the protruding part of the first frame plate 4. With the gradual rising of the second frame plate 5, the second frame plate 5 will gradually contact the clamping plate 3 on both sides and exert an upward guiding force, so that the second frame plate 5 is located at the axial level position of the larger diameter steel coil body 2, improving the centering and clamping stability of the clamping plate 3, so that the clamping plate 3 will not be pressed downward by the weight of the steel coil body 2 when facing the larger diameter steel coil body 2, causing clamping failure or the opening of the clamping plate 3, further improving the clamping force and structural stability of the clamping plate 3 to the steel coil body 2, ensuring that it always remains closely fitted during dynamic transportation or hoisting, effectively preventing the steel coil body 2 from axially shifting or circumferentially loosening;
[0051] When it is necessary to unload the steel coil body 2, the screw rod 91 is reversed, and the second frame plate 5 is lowered until the second frame plate 5 is recombined with the protruding part of the first frame plate 4. When the second frame plate 5 is combined with the protruding part of the first frame plate 4, the first frame plate 4 and the clamping plate 3 are gradually separated from each other as the second frame plate 5 continues to move downward. In the process of the gradual separation of the first frame plate 4 and the clamping plate 3, the filling shaft 112 is reversely moved, the trigger plate 121 is reset and the vertical plate 122 is lifted, at this time, the polymerization spring 132 pushes the polymerization plate 133 to move upward, so that the polymerization plate 133 slides in the sliding groove 134 and gradually passes through the polymerization groove 135 to reapply the guiding constraint to the slope at the bottom of the lifting plate 101, so as to promote the four equal parts of the lifting plate 101 to recombine. The lifting plate 101 slides along the limiting groove 104 under the guidance of the polymerization groove 135 and gradually closes until it is completely reset. At this time, the tension spring 136 restores the initial tension to prepare for the next clamping action. As the lifting plate 101 recombines, the screw groove 102 in the lifting plate 101 is recombined with the screw rod 91, and the screw rod 91 gradually establishes stable engagement with the lifting plate 101 in the process of continuing to rotate, so as to restore the power transmission path and drive the lifting plate 101 to synchronously descend as a whole. In the process of the descent of the lifting plate 101, the first frame plate 4 combined with the top of the lifting plate 101 moves downward, so that the first frame plate 4 and the second frame plate 5 jointly descend until they are completely reset. In this process, the clamping plate 3 gradually separates from the first frame plate 4 and the second frame plate 5 and naturally opens under the action of gravity. After the clamping plate 3 is completely opened, the staff can smoothly take down the steel coil body 2. The clamping and releasing process is smooth and efficient, fully meets the operation requirements of steel coils of different diameters, significantly improves the loading and unloading efficiency and operation safety, and provides reliable protection for continuous and high-strength steel logistics transportation.
