Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailer boxes, and specifically relates to a steel coil tooling for a semi-trailer box. Background Art

[0002] A semi-trailer is a trailer with axles placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and equipped with a coupling device that can transfer horizontal and vertical forces to the tractor. Generally, a semi-trailer is a three-axle semi-trailer, and its types include eleven-meter barn semi-trailers, thirteen-meter barns, low-bed semi-trailers, etc. It is a heavy transportation vehicle connected to the semi-trailer head through a kingpin.

[0003] The semi-trailer box has good transportation and loading capacity. Therefore, when transporting long-distance and large-quality goods, a semi-trailer box is usually selected for transportation. During the transportation process of the semi-trailer box, there are relatively large safety hazards in the transportation of steel coils. The main problem is that the quality of the steel coil is relatively large. When the external force changes, once the steel coil starts to move, its inertia is relatively large, which will pose a great threat to the surrounding environment. The fixing method using ropes is not stable enough. When using a special carriage for transportation, the cost is relatively high, and the transportation of the vehicle is single, increasing the transportation cost of the driver, which is not conducive to adapting to the market. For this reason, we propose a steel coil tooling for a semi-trailer box. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a steel coil tooling for a semi-trailer box, which solves the problems raised in the above background art.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A steel coil tooling for a semi-trailer box includes a bottom plate. Above the bottom plate is provided a top plate. The outside of the bottom plate and the top plate is sleeved with a carriage wall. Inside the top plate is movably sleeved with a lifting column. On the upper surface of the bottom plate is fixedly supported a telescopic column. The output shaft of the telescopic column is connected to a support frame. Inside the top plate is movably sleeved with a limiting rod, and the bottom end of the limiting rod is fixedly connected to a support spring.

[0006] Optionally, a servo motor is fixedly sleeved inside the lifting column. The top end of the output shaft of the servo motor is fixedly connected to a driving gear. Inside the lifting column are movably sleeved with two driven gears. Outside the driven gears near the top end is fixedly sleeved with a support disk.

[0007] Optionally, the top surface of the support frame is in contact with the bottom surface of the lifting column. The vertical section of the support frame is inclined at a position away from the telescopic column.

[0008] Optionally, the top end of the lifting column extends upward above the top plate. The bottom end of the support spring is in contact with the top surface of the bottom plate. The top end of the limiting rod extends upward above the top plate.

[0009] Optionally, the diameter value of the support disk is smaller than the diameter value of the lifting column, and the two driven gears are symmetric with each other along the axis of the lifting column.

[0010] Optionally, the outer sides of the driving gear and the driven gear are meshed with each other, and the axes of the driving gear and the lifting column are located on the same vertical line.

[0011] The utility model provides a steel coil tooling for a semi-trailer box, which has the following beneficial effects:

[0012] 1. For the steel coil tooling of the semi-trailer box, through the arrangement of the bottom plate and the top plate, a lifting column is movably sleeved inside the top plate, a telescopic column is supported above the bottom plate, and a support frame is fixedly connected to the outside of the output shaft of the telescopic column. The support frame can be used to support the lifting column, so as to control the position of the lifting column, make the lifting column rise or fall, and enable the vehicle bottom plate to normally transport other goods without fixing the steel coil.

[0013] 2. For the steel coil tooling of the semi-trailer box, a limiting rod located outside the lifting column is movably sleeved inside the top plate, and the bottom end of the limiting rod is connected to the bottom surface of the bottom plate through a support spring. When transporting the steel coil, the support spring can be used to support the limiting rod, and the limiting rod is used in cooperation with the support disk inside the lifting column to support the steel coil. At the same time, when transporting ordinary goods, under the action of gravity, the limiting rod will not cause interference. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Please refer toFigures 1 to 4 , the utility model provides a technical solution: a steel coil tooling for a semi-trailer box, including a bottom plate 1, a top plate 2 is arranged above the bottom plate 1, the top end of the lifting column 3 extends upward above the top plate 2, the bottom end of the support spring 11 is in contact with the top surface of the bottom plate 1, the top end of the limiting rod 10 extends upward above the top plate 2, the cooperation of the bottom plate 1 and the top plate 2 can complete the storage of the lifting column 3 and the limiting rod 10, improve the function of the carriage, improve the universality of application. At the same time, the setting of the lifting column 3 and the cooperation of the support plate 7 can complete the stable fixation inside the steel coil, and the limiting rod 10 can complete the stable fixation on the side of the steel coil. The outer part of the bottom plate 1 and the top plate 2 is sleeved with a carriage wall, the lifting column 3 is movably sleeved inside the top plate 2, the top surface of the support frame 9 is in contact with the bottom surface of the lifting column 3, the vertical section of the support frame 9 is inclined at a position away from the telescopic column 8. The setting of the telescopic column 8 plays a role in controlling the position of the support frame 9. By using the setting of the telescopic column 8, the position of the lifting column 3 can be controlled, and then the position of the steel coil can be restricted. At the same time, when transportation is not required, the lifting column 3 is controlled to drop into the top plate 2 to ensure that the top surface of the top plate 2 is horizontal and other goods can be placed arbitrarily. The telescopic column 8 is fixedly supported on the upper surface of the bottom plate 1, the output shaft of the telescopic column 8 is connected with the support frame 9, the limiting rod 10 is movably sleeved inside the top plate 2, the bottom end of the limiting rod 10 is fixedly connected with the support spring 11, and the setting of the support spring 11 plays a role in supporting the limiting rod 10. During the use process, the position of the limiting rod 10 can be restricted through the cooperation of the support spring 11. The steel coil will press down part of the limiting rod 10, and then part of the limiting rod 10 will be pressed down into the top plate 2. The cooperation of part of the limiting rod 10 can complete the restriction of the position of the steel coil.

[0021] A servo motor 4 is fixedly sleeved inside the lifting column 3, the top end of the output shaft of the servo motor 4 is fixedly connected with a driving gear 5, the outer sides of the driving gear 5 and a driven gear 6 are meshed with each other, the axis of the driving gear 5 and the axis of the lifting column 3 are located on the same vertical line. By controlling the rotation of the servo motor 4, the output shaft of the servo motor 4 drives the driving gear 5 to rotate. During the rotation of the driving gear 5, the driven gear 6 will be driven to rotate, and at the same time, the driven gear 6 will drive the support plate 7 to rotate around the axis of the driven gear 6, and the fixation of the steel coil is completed by using the support plate 7. Two driven gears 6 are movably sleeved inside the lifting column 3, a support plate 7 is fixedly sleeved on the outer part of the driven gear 6 near the top end. The setting of the support plate 7 can complete the fixation of most steel coils, ensure the stability of use, and facilitate the use of the equipment. At the same time, the setting of the driven gear 6 can control the support plate 7. Through the rotation of the support plate 7, the inner side of the steel coil is stably supported. The diameter value of the support plate 7 is smaller than the diameter value of the lifting column 3, and the two driven gears 6 are symmetric with each other along the axis of the lifting column 3.

[0022] In summary, when transporting the steel coil with this semi-trailer steel coil tooling, the steel coil is lowered downward from above the top plate 2 and aligned with the axis of the lifting column 3, so that the axis of the inner sleeve of the steel coil is as close as possible to the axis of the lifting column 3. During the process of lowering the steel coil, the steel coil will press down some of the limiting rods 10, and then press some of the limiting rods 10 into the interior of the top plate 2. The cooperation of some of the limiting rods 10 can complete the limitation of the position of the steel coil. Subsequently, control the rotation of the servo motor 4, and use the output shaft of the servo motor 4 to drive the driving gear 5 to rotate. During the rotation of the driving gear 5, it will drive the driven gear 6 to rotate. At the same time, the driven gear 6 will drive the support disc 7 to rotate around the axis of the driven gear 6, and use the support disc 7 to fix the steel coil. During non-carrying operations in daily life, first use the servo motor 4 to control the two support discs 7 to retract into the interior of the lifting column 3, and then control the output shaft of the telescopic column 8 to retract. Use the output shaft of the telescopic column 8 to drive the support frame 9 to retract, so that the lifting column 3 slowly drops downward until the top surface of the lifting column 3 fits the top surface of the top plate 2, and that's it.
