The application relates to a carrying device for carrying a web. The coiled material is placed above the bearing device, the bearing device is used for supporting the coiled material, and the bearing device is transported and carried, so that the coiled material is transported and carried. In the process, transportation equipment such as a forklift, a crane and the like directly acts on the bearing device and avoids direct contact with the coiled material, so that the coiled material is protected. Of course, the carrying device can also be used for carrying other objects and transporting and carrying the objects.

In the prior art, as shown in fig. 1, the bottom end of the coil 20 is placed on the upper surface 110 of the tray 100 of the carrying device 10, all positions of the upper surface 110 of the tray 100 are on the same horizontal plane, and an included angle α close to 90 ° is formed between the bottom end of the outer edge 21 of the coil 20 and the upper surface 110 of the tray 100. when the coil 20 collides with the tray 100, the outer edge 21 of the coil 20, particularly the outer edge (the area shown by the dotted line in the figure) of the bottom end of the coil 20 is easily damaged.

As shown in fig. 2, in the present application, the carrying device 10 includes a tray 100 and a supporting foot 200 fixed below the tray 100, and the roll material can abut against the upper surface 110 of the tray 100.

As shown in fig. 3, the upper surface 110 has a first boundary 101, a second boundary 102 and a third boundary 103, and the second boundary 102 surrounds the first boundary 101 and the third boundary 103 surrounds the second boundary 102. Wherein the second border 102 has dimensions comparable to the dimensions of the outer edge of the bottom end of the web. As shown in fig. 4, 5, and 8, the abutting region 105 is formed inside the first boundary 101, the first boundary 101 and the third boundary 103 enclose a relief region 104, and the relief region 104 is recessed downward to form a relief groove 120. As shown in fig. 6, the depth H of the relief groove 120 at the second boundary 102 is equal to or greater than the depth of the relief groove 120 at other positions. In the present embodiment, the coil has a cylindrical shape, and the outer edge of the base end has a circular shape, so that the second boundary 102 also has a circular shape, and the diameter of the second boundary 102 is the same as the diameter of the coil. The first boundary 101 and the third boundary 103 are both circular, the diameter of the first boundary 101 being smaller than the diameter of the second boundary 102, and the diameter of the third boundary 103 being larger than the diameter of the second boundary 102. Of course, the first boundary 101 and the third boundary 103 may also have other shapes, such as rectangular, triangular, or other irregular shapes. Of course, when the carrier 10 is used to transport other shaped objects, the shape of the second boundary 102 is determined based on the shape of the outer edge of the bottom end of the object.

When the coil is placed against the tray 100, the coil is placed against the second border 102 and down until the coil is placed on the tray 100. At this point, the bottom end of the web is brought into close abutment against the abutment area 105 enclosed by the first border 101. The outer edge of the bottom end of the roll is spaced from the tray 100 or hard contact of the bottom end of the roll with the tray 100 is avoided. Especially, the outer border of coiled material corresponds and sets up in the top on second border 102, and the outer border of coiled material is along the great distance with the bottom surface 121 interval of recess for when bearing device 10 drives the coiled material and take place vibrations, avoid coiled material and tray 100 to bump the atress, thereby avoid the damage of tray 100 to the outer border of the bottom of coiled material, with the security of assurance coiled material in the transportation. By providing the first and third boundaries 101 and 103, it is ensured that the outer edge of the coil deviates from the second boundary 102 in size and position during the coil manufacturing process, the coil being placed on the tray 100, or the coil being transported in a proper scale. At the same time, the same carrier 10 is made to be able to accommodate more rolls of similar size.

As shown in fig. 6, the depth H of the escape groove 120 gradually increases within the second boundary 102 in the direction X from the first boundary 101 toward the second boundary 102, and the bottom surface 121 of the escape groove 120 smoothly connects with the upper surface 110 of the tray 100. In the above arrangement, an excessive included angle between the inner wall surface of the avoiding groove 120 close to the first boundary and the upper surface 110 of the tray can be avoided, and when the upper surface 110 contacts with the coil due to the excessive included angle at the first boundary 101, a stress concentration situation occurs at the bottom end of the coil, thereby protecting the coil. In the present embodiment, the depth of the escape groove 120 is the same in the region surrounded by the second boundary 102 and the third boundary 103. Of course, the depth of the escape groove 120 may be gradually reduced in the direction X from the first boundary 101 to the second boundary 102 in the region surrounded by the second boundary 102 and the second boundary 102.

As shown in fig. 7, the blocked area 106 is formed within the second boundary 102, and since the second boundary 102 has a size corresponding to the outer edge of the bottom end of the web, the orthographic area of the web coincides with the blocked area 106 when the web is placed on the tray 100. The ratio of the area of the abutting region 105 to the area of the shielding region 106 is 0.7 or more and 0.9 or less. With the above arrangement, it is ensured that the tray 100 has a sufficient area contacting the coil 20 while reducing damage to the outer edge of the bottom end of the coil 20, so as to ensure that the tray 100 can stably support the coil 20.

Further, the diameter of the first boundary 101 is 1000 mm or more and 1020 mm or less. The diameter of the second boundary 102 is 1090 mm or more and 1110 or less; the diameter of the third boundary 103 is 1160 mm or more and 1180 mm or less. In this embodiment, the diameter of the first boundary 101 is 1010 mm, the diameter of the second boundary 102 is 1100 mm, and the diameter of the third boundary 103 is 1175 mm. In actual use, the outer diameter of the coil 20 is typically 1100 mm, and the first border 101 is set to 1100 mm in diameter to better fit the coil 20. Also, with this arrangement, the ratio of the area of the abutting region 105 to the area of the shielding region 106 is 0.84.

Further, as shown in fig. 2, the tray 100 has a rectangular pillar shape, and the upper surface 110 thereof has four corners 130. Of course, in other embodiments, the tray 100 may have other shapes, and the shape determines the number of the corners 130. The third boundary 103 is remote from the corner 130 of the upper surface 110. With the above arrangement, the planes in which the corners 130 of the tray 100 are located coincide and are all horizontal. The corners 130 in the horizontal plane are beneficial to improve the stability of the stacked placement of the plurality of carriers 10 in the vertical direction when the plurality of carriers 10 are stacked.

As shown in fig. 2 and 9, the number of the supporting legs 200 is plural, and the supporting legs 200 are fixedly disposed below the tray 100. In two adjacent carriers 10, the supporting foot 200 of the upper carrier 10 can abut against the upper surface 110 of the tray 100 of the lower carrier 10. In this embodiment, the supporting legs 200 are made of steel pipes, and the number of the supporting legs 200 is 3. The supporting legs 200 extend from one end of the tray 100 to the other end of the tray 100, which is oppositely disposed. When a plurality of carriers 10 are stacked in a vertical direction, the support legs 200 at both sides of the upper carrier 10 can abut against the corners 130 of the tray 100 of the lower carrier 10, and the support leg 200 at the center of the upper carrier 10 can abut against the abutting area 105 of the lower carrier 10, so as to ensure balance and stability when a plurality of carriers 10 are stacked. Of course, in other embodiments, the number of the supporting legs 200 may be 2, 4 or more. In fig. 2 and 9, the relief groove on the upper surface of the tray 100 is not shown.

Further, as shown in fig. 10, the carrying device 10 further includes a plurality of anti-slip blocks 300, the number of the anti-slip blocks 300 is plural, the plurality of anti-slip blocks 300 are fixedly disposed on the upper surface 110 of the tray 100, and when the coil is disposed on the carrying device, the upper surface 110 of the anti-slip blocks 300 is higher than the upper surface 110 of the tray 100. When the coil 20 is placed on the tray 100, the stoppers 300 are pressed and deformed, and the stoppers 300 increase the coefficient of friction between the tray 100 and the coil 20, so that the coil 20 can be more stably seated on the tray 100 and move along with the tray 100. In the embodiment, the material of the anti-slip block 300 is rubber, but in other embodiments, the anti-slip block 300 may be other materials capable of increasing the friction coefficient. Each anti-slip block 300 may be an integrally formed member, and the anti-slip block 300 may also be a member formed by splicing a plurality of rubber blocks.

Further, as shown in fig. 11, the supporting device 10 further includes a protection layer 400, and the protection layer 400 is disposed above the tray 100. In actual use, the protective layer 400 is disposed on the tray 100, and the roll 20 is disposed on the protective layer 400. The protective layer 400 may be deformed, and the protective layer 400 may serve as a buffer when the tray 100 and the web 20 move relative to each other. In this embodiment, the protection layer 400 is made of corrugated paper, which is low in cost, and can deform effectively to achieve a better shock absorption effect. Of course, in other embodiments, the protection layer 400 may be made of other deformable materials. In actual use, when the roll 20 is placed on the tray 100, the rubber is elastically deformed so that the plane in which the upper surface of the rubber lies approximately coincides with the plane in which the upper surface 110 of the tray 100 lies. The anti-slip blocks 300 shown in the drawings have a certain thickness, which is only for illustration.

The ratio of the depth of the relief groove 120 at the second boundary 102 to the thickness of the protective layer 400 is equal to or greater than 1/2. So that the relief groove 120 can be used to accommodate the deformed protective layer 400. In this embodiment, when the roll 20 is placed on the protective layer 400, the protective layer 400 of corrugated paper is compressed and its thickness is reduced to half of the original thickness. The protective layer 400 in the relief area 104 enters the relief groove 120 to provide more effective cushioning of the tray 100 and the web 20 and protect the outer edge of the web 20.

In the present embodiment, the thickness of the protection layer 400 is equal to or greater than 4 mm and equal to or less than 6 mm, and the depth of the avoiding groove 120 at the second boundary 102 is equal to or greater than 2 mm and equal to or less than 3 mm. A large number of experiments show that when the thickness of the protective layer 400 made of corrugated paper is greater than or equal to 4 mm and less than or equal to 6 mm, the protective layer 400 can play a better protective role, and the protective layer 400 cannot influence the installation and fixation of the coiled material 20 and the tray 100 due to the overlarge thickness.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
