Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1

The fixed tray comprises a tray 1 for bearing cylindrical goods and a stop component for stopping the cylindrical goods from displacing on the tray 1, wherein the stop component comprises a circumferential stop component 2 for preventing the cylindrical goods from circumferentially rolling, and the circumferential stop component 2 comprises two circumferential stops 2-1; (from fig. 2A two circumferential stop assemblies 2 are shown, a1 and a2 showing one circumferential stop assembly 2 and a3 and a4 showing the other circumferential stop assembly 2). The fixed tray is mainly used for carrying cylindrical goods, and the "cylindrical goods" refers to heavy material coils such as steel coils, copper coils and aluminum coils, and the following embodiments also take steel coils as an example for description.

The steel coil is also called coil steel. The steel is hot-pressed and cold-pressed into a roll shape, and the whole body is cylindrical. Various processes (e.g., processing into steel sheets, steel strips, etc.) are convenient for storage and transportation. At present, a steel coil does not have a special fixing device in the transportation process, and accidents are easy to happen.

The fixing tray provided by the above scheme can provide circumferential stopping for the steel coil (i.e. prevent the rolling of the steel coil), so the circumferential stopping component 2 comprises two circumferential stopping parts 2-1 which provide opposite-direction stopping for the steel coil, and the circumferential stopping parts 2-1 are used for stopping the rolling of the steel coil.

Since the size of the steel coil carried each time is not fixed, the above solution is difficult to adapt to the steel coils with different sizes.

In order to solve the above-mentioned problem, as shown in fig. 2A, the circumferential stopper 2-1 of the fixed tray of the present embodiment includes a fixed stopper seat 2-11 and a movable stopper seat 2-12; the distance between the two fixed stop seats 2-11 of one circumferential stop assembly 2 is fixed (i.e. the positions of the fixed stop seats 2-11 and the tray 1 are fixed, so that the positions of the fixed stop seats 2-11 and the tray 1 are fixed in various ways, for example, the fixed stop seats 2-11 and the tray 1 are directly fixed by conventional ways such as bolts); the distance between two movable stop seats 2-12 of one circumferential stop assembly 2 is changed by adjusting the relative position between the movable stop seat 2-12 and the fixed stop seat 2-11.

Taking fig. 2A as an example, the movable stop seats 2-12 of a1-a2 and/or a3-a4 are adjusted, so that the distance between the movable stop seats 2-12 of a1 and a2 and/or the distance between the movable stop seats 2-12 of a3 and a4 becomes larger or smaller.

In one embodiment, the solution to "the distance between the two fixed stop seats 2-11 of one circumferential stop assembly 2 is fixed" described above is: tray 1 uses chinese utility model patent: in the tray of 2021220149921 or 2021220133694, because the tray 1 is provided with the through hole 1-1 (named as the first through hole in 2021220149921 and named as the connecting through hole in 2021220133694), as shown in fig. 3, the lower portion of the fixed stop seat 2-11 is provided with the projection 2-14 (the projection 2-14 and the fixed stop seat 2-11 may be fixedly connected or integrally formed) complementary to the shape of the through hole 1-1, when in use, the projection 2-14 is directly inserted into the through hole 1-1, because the weight of the steel coil is large, the fixed stop seat 2-11 can ensure the relative fixation between the fixed stop seat 2-11 and the tray 1 without performing an additional fixing manner with the tray 1. This also has an advantage that the circumferential stopper 2-1 can be directly removed from the tray 1 after the coil is detached from the tray 1, and the tray 1 can be stacked to reduce the space as much as possible.

As shown in fig. 1 and 2A, the tray 1 is further provided with fixing holes 1-2, and after the steel coil is placed on the fixing tray, in order to ensure the stability between the tray 1 and the steel coil, the steel coil is bound on the tray 1 along the circumferential direction of the steel coil by using a binding band 5 through the fixing holes 1-2.
