DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0025] like Figure 3-8 As shown, the technical solution of the present invention provides a cross-arm transfer shuttle, comprising a mother car 1 and a child car 4 mounted on the mother car 1. The mother car 1 comprises a mother car body 2 and a child car running track 3 disposed on the mother car body 2, and the running base 5 is slidably connected to the child car running track 3. The child car 4 comprises, from bottom to top, a running base 5, a lifting base 6, a rotating base 7 mounted on the lifting base 6, and a rotating material receiving assembly disposed on the rotating base 7.

[0026] The walking base 5 is slidingly connected to the mother vehicle 1, and the jacking base 6 is connected to a jacking drive member for driving the jacking base 6 to move up and down. The rotating material receiving assembly includes a rotating drive member, a material receiving base 8 driven by the rotating drive member, and four material receiving arms 9 arranged on the material receiving base 8. The angle between two adjacent clamping arms is 90 degrees.

[0027] The mother car moves on the mother car running track 14 on the ground, and the connecting points 15 are located on both sides of the mother car running track 14. The coiled goods 16 to be transferred are placed at the connecting points 15. After the mother car 1 arrives at the pickup point, the sub-cart 4 walks on the sub-cart running track 3 on the mother car 1. The walking direction of the mother car 1 is perpendicular to the walking direction of the sub-cart 4, and it moves close to the coiled goods 16 until the receiving arm 9 is inserted into the socket of the coiled goods 16. At this time, the jacking drive drives the jacking base 6 to rise, and then indirectly drives the receiving arm 9 to move upward, wherein the jacking drive can be implemented by a structure such as a hydraulic cylinder. After the receiving arm 9 lifts the goods, the sub-cart 4 moves back again to complete the picking work. The position of the receiving arm 9 can be exchanged by rotating the drive until all four receiving arms 9 are loaded with goods.

[0028] Traditional mother-and-child carts can only connect one cargo at a time, with low transfer efficiency, and are not suitable for occasions where higher transfer efficiency is required. In this solution, the four receiving arms 9 are arranged in a cross shape for connecting cargoes, and can connect four cargoes at a time, with high transfer efficiency and reduced operating costs.

[0029] The receiving arms 9 extend horizontally outward from the receiving base 8, and each receiving arm 9 transfers a coiled cargo 16. One receiving arm 9 includes two receiving rods 10 spaced apart, and the receiving surface of the receiving rods 10 is configured as an arc surface, and the curvature is adapted to the curvature of the inner surface of the insertion hole on the coiled cargo 16.

[0030] In this solution, the material receiving rod 10 is relatively long, so there is no need to lay a ground track for the sub-trolley. The sub-trolley only needs to run on the sub-trolley running track 3 to receive the coiled goods 16. At the same time, to prevent derailment, mechanical barriers can be installed at both ends of the sub-trolley track. Compared with the existing technology of setting up sub-trolley tracks on the ground, this solution makes the material receiving process safer. The curved surface structure of the material receiving rod 10 can conform to the surface of the insertion hole of the coiled goods 16, preventing the goods from falling off to a certain extent.

[0031] The rotary drive assembly includes a rotary drive motor 11, a driving gear 12 connected to the output end of the rotary drive motor 11, and a driven gear 13 meshing with the driving gear 12. The driven gear 13 is connected to the material receiving base 8. The diameter of the driving gear 12 is smaller than that of the driven gear 13. The rotation of the rotary drive motor 11, in conjunction with the driving gear 12 and the driven gear 13, causes the material receiving base 8 to rotate. The material receiving base 8 can rotate 90 degrees at a time, switching the position of the material receiving arm 9.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
