Child and mother vehicle

Abstract

The invention discloses a child and mother vehicle, and belongs to the technical field of transportation equipment. The child and mother vehicle is used for transporting workpieces into and out of a target bin position, and comprises a motion control system; a mother vehicle, wherein the mother vehicle comprises a rack and a bearing platform arranged on the rack, the rack can move back and forth in the X direction, and the bearing platform can ascend and descend in the Z direction; a child vehicle arranged on the bearing platform, capable of ascending and descending along with the bearing platform and capable of moving back and forth in the Y direction relative to the mother vehicle; and a butt joint device, wherein the butt joint device comprises an X-direction positioning portion movablyarranged on the bearing platform, and the X-direction positioning portion is used for being in positioning butt joint with the target bin position. The workpieces can be carried to a three-dimensional warehouse, and the child vehicle does not shake when passing through rails from the bearing platform to the target bin position.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a mother and child vehicle. Background technique [0002] In prefabricated buildings, the manufacture of prefabricated components is generally completed in advance in professional factories. After the prefabricated components are manufactured, they are generally stored in the prefabricated component yard. [0003] In the prior art, the prefabricated component storage yard is generally a flat storage, and the area occupied by the storage yard is often 1.2-2 times the area of ​​the prefabricated component production line. The stockyards in the state of flat storage have technical problems such as high land cost, low turnover efficiency, low land volume ratio, and low output value per unit of land. [0004] Therefore, the storage of prefabricated components has gradually developed from flat storage to three-dimensional storage. However, in the prior art, when tra...

Problems solved by technology

However, in the prior art, when transportation equipment is used to transport prefabricated components to the three-dimensional storage, for example, a sub-car is used for handling operations, and the motion control system on the sub-car can ensure that the sub-car moves to the working position. When entering the three-dimensional warehouse, the mother car is generally controlled to move to the designated position through the motion control system, and then the sub-car is lifted vertically to the designated height for operation, but the mother car is initially positioned through the motion control system, and the mother car is lifted There is a certain amount of sloshing that causes the offset, resulting in inaccurate docking positions between the sub-car rails of the sub-car and the track of the three-dimensional storage. Due to the inaccurate docking position, the sub-car often shakes when it enters the three-dimensional storage, resulting in inaccurate workpiece transportation. stable
