Example 3:
the present embodiment is a method for replacing a core box 2 by using the core sorting apparatus of embodiment 2, as shown in fig. 4 to 8, the method for replacing a core box 2 includes the following steps:
In the first step, referring to fig. 4-8, the core transfer box 1 is placed in each core grid of the core box 2 filled with the soft fragile core in an inverted mode, wherein the box body extending pieces 121 at the opening edge of the core transfer box 1 are downwards aligned with the inner walls of the core grids of the core box 2 until the box bottom of the core transfer box 1 is flush with the top line of the core grids, and the box body extending pieces 121 of the core transfer box 1 are tightly attached to the grid bottom of the core grids and semi-wrap the soft fragile core.
Further, the box body extension piece 121 enters the core lattice and is acted by the inward attraction, and automatically contracts inwards after entering the core lattice. The box extension piece 121 comprises a lower vertical section 1212 and an upper concave arc section 1211, wherein the upper concave arc section 1211 is bent inwards and is used for encircling a columnar core in the core lattice in the inserting process.
The core box 2 is a core box 2 commonly used in the prior art, and generally comprises three core grids sequentially arranged, wherein each core grid can be used for placing a soft and fragile core.
Because the box body extension pieces 121 have an inward attraction effect, the box body extension pieces 121 automatically shrink inwards after entering the core grids, and when the core transfer box 1 completely enters the core grids, the grids of the core grids of the box body extension pieces 121 are tightly attached, so that the state that the box body extension pieces 121 of the core transfer box 1 are semi-wrapped with the soft and fragile core is achieved. The remaining other core grids are completed into the box according to the scheme.
A fixed rod mechanism 3 is additionally arranged between the core transfer box 1 and the core box 2, a first fixed cross rod 31 of the fixed rod mechanism 3 is additionally arranged on the core transfer box 1, a second fixed cross rod 32 of the fixed rod mechanism 3 is additionally arranged on the core box 2, and a connecting component 33 is connected with the first fixed cross rod 31 and the second fixed cross rod, so that the core transfer box 1 and the core box 2 form an assembly structure;

Then, the new core box 2 'is reversely buckled on the core transfer box 1 until the box bottom of the core transfer box 1 is flush with the top line of the core lattice of the new core box 2', an assembly structure is formed again, and the assembly structure of the new core box 2 'with the reversely buckled structure is turned by 180 degrees through the turnover table mechanism 4, so that the replacement of the core box can be completed, and the soft and fragile core is completely and in-situ transferred into the new core box 2'.
In the process of replacing the core box 2, under the protection of the box body extension piece 121 and the core transfer box 1, the soft fragile core is always and stably fixed in the core transfer box 1, and the original structure, construction, deposition sequence and the like of the core are not changed.
Compared with the traditional method that when the soft and fragile core is manually transferred by using a shovel, the method needs to be transferred for multiple times, and has a low speed (each group needs 2 people and 4-5 minutes/meter), the method can completely solve the problems that the manual speed is low, the man-made dominant factors are many, and the original state of the soft and fragile core is damaged (the original core is broken more, the layer structure and geological structure phenomena (morphology) are damaged, the original length of the core is shortened or lengthened, and the core precipitation sequence is changed in a misplacement manner), greatly improves the transferring and replacing efficiency of the soft and fragile core, and has the replacing speed of only 1-2 minutes/meter, and because the overturning table mechanism can only carry out 180-degree overturning (one gear), the main pipe judgment of technicians on the horizontal direction and the rotating angle is reduced again, the machine-like modeling working flow is realized, and the complete wrapping and transferring and replacing of the core are ensured.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
