[0025] Example:

[0026] like Figure 1 As shown, this embodiment provides a transport tooling for a subway train traction / auxiliary reverse electrical box, including a main frame 1 and a plurality of fixing units located inside the main frame 1.

[0027] As can be seen from the figure, the main frame 1 includes an opening for accommodating the traction / auxiliary reverse electrical box, the side walls of the main frame 1 are composed of multiple strip structures, and the bottom is composed of multiple strip structures and plate structures distributed in a grid. The grid distribution at the bottom includes: a first strip structure 11, a second strip structure 12, a first plate structure 13, a second plate structure 14, a third strip structure 15 and a fourth strip structure 16 arranged from left to right, and a fifth strip structure 17, a sixth strip structure 18 and a seventh strip structure 19 arranged from back to front. The ends of the first strip structure 11, the fourth strip structure 16, the fifth strip structure 17 and the seventh strip structure 19 are fixedly connected to each other to form a rectangular bottom of the main frame 1, and the rectangular bottom is located on a horizontal plane; the two ends of the sixth strip structure 18 are respectively fixedly connected to the middle positions of the first strip structure 11, the second strip structure 12, the first plate structure 13, the second plate structure 14, the third strip structure 15 and the fourth strip structure 16; the two ends of the second strip structure 12, the first plate structure 13, the second plate structure 14 and the third strip structure 15 are respectively fixedly connected to the fifth strip structure 17 and the seventh strip structure 19. The opening of the main frame 1 is a rectangle formed by the ends of the four strip structures connected together, the plane where the rectangular opening is located is parallel to the plane where the rectangular bottom is located, and the opening and the bottom are fixedly connected by multiple strip structures, thereby forming the side wall of the main frame 1.

[0028] Each group of fixing units includes a limiting element, a supporting element and a strap fixing seat. As can be seen from the figure, the four groups of fixing units are symmetrically distributed along the midline of the side length of the main frame 1, that is, they are symmetrical along the straight line where the sixth strip structure 18 is located, and they are symmetrical along the midline of the fifth strip structure 17 and the seventh strip structure 19. In this embodiment, the limiting element includes four limiting blocks, Figure 1 The transport tooling comprises a limit block 2 located at the lower left of the main frame 1, and the other three limit blocks are respectively located at the upper left, upper right and lower right. The four limit blocks respectively bear the four connecting parts of the electrical box to fix the traction / auxiliary reverse electrical box.

[0029] The supporting element includes four supporting columns, which respectively support the four limit blocks mentioned above. Figure 1The transport tooling includes a support column 3 located at the upper left of the main frame 1. The support column 3 includes two perpendicular strip structures. The vertical strip structure is fixedly connected to the second strip structure 12, and the horizontal strip structure is fixedly connected to the strip structure on the side wall of the main frame 1. Therefore, the support column 3, the second strip structure 12, and the strip structure on the side wall together form a small rectangle, thereby providing a stable support for the limiting element. In some other embodiments, strip structures can be added to the diagonal of the small rectangle to further improve the stability of the support, thereby improving the stability of the electrical box transportation. The strap fixing seat 4 is installed on the third strip structure 15 and is located close to the bottom of the corresponding support column.

[0030] The above four limit blocks are fixedly connected or movably connected to the support columns at the corresponding positions, and jointly support the force-bearing parts of the box body, so that the box body is suspended in the air, and the box body is protected to the greatest extent. At the same time, each limit block limits the displacement of the electrical box during transportation, reducing the damage to the box body caused by excessive bumps, and each strap fixing seat can cooperate with the strap to further strengthen the fixation of the electrical box and enhance the reliability of the overall tooling.

[0031] In addition, if Figure 2 As shown, the traction / auxiliary reverse electrical box is controlled to be installed into the main frame 1 through the lifting equipment and the sling. At this time, the sum of the heights of the supporting elements, the limiting elements and the traction / auxiliary reverse electrical box is less than the height of the main frame 1, that is, the capacity of the main frame 1 matches the traction / auxiliary reverse electrical box, and the electrical box is completely sunk into the main frame 1, which can better protect the box from external damage. On this basis, a movable top cover can be installed at the opening of the main frame 1 to protect the electrical box from the influence of the external environment, such as rain, dust, etc.

[0032] In some other embodiments, a buffer portion may be provided on the limiting element, or a buffer material may be provided to achieve a shock-absorbing and buffering effect, thereby reducing the impact of vibration on the electrical box and further ensuring the stability of transportation.

[0033] The transport tooling provided in this embodiment utilizes the original installation and fixing structure of the subway train traction / auxiliary reverse electrical box. It can be quickly hoisted and placed on the limiting element and the supporting element to limit the electrical box as a whole within the main frame 1. At the same time, through the limiting effect of the limiting element, the displacement space of the subway train traction / auxiliary reverse electrical box is very small. In view of the fact that the subway train traction / auxiliary reverse electrical box often needs to be transported over long distances and the road conditions are complicated, in order to better cope with this situation, a strap fixing seat is added to further strengthen the fixation of the electrical box, and a strap is used to increase the stability of the electrical box during transportation. The special tooling for transporting the subway train traction / auxiliary reverse electrical box can reduce unnecessary transportation damage and reduce the maintenance work caused by damage caused by transportation. It not only improves the safety of the subway train traction / auxiliary reverse electrical box during transportation, but also reduces the workload of staff and reduces maintenance costs.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
