Description

Jacking freight trolley Technical Field The utility model relates to the technical field of freight trolleys, in particular to a jacking freight trolley. Background An AGV (Automated Guided Vehicl, also called an automatic guided vehicle) is equipped with an automatic guiding device such as an electromagnetic or optical device, which can travel along a predetermined guide path and has safety protection and various transfer functions. The control of the AGV system is completed through the mutual cooperation among the logistics upper scheduling system, the AGV ground control system and the AGV vehicle-mounted control system. The automatic guided vehicle can flexibly, accurately and efficiently carry out material handling and is widely applied to flexible manufacturing workshops. The AGV with multiple carriers can simultaneously carry multiple workpieces, has strong carrying flexibility, and has stronger complexity and multiple constraint of a path planning problem and higher solving difficulty. In the prior art, when using AGV to transport the goods on the goods shelves, generally need the AGV to remove under the goods, then jack-up the goods through elevating system, then remove the goods from the goods shelves through the removal of AGV to transport, and in this process, the position that causes the AGV to stop easily differs with the transport position of goods, thereby cause inconsistent between freight and the goods tray of AGV, cause the goods to drop in the transportation easily, its transportation stability is low. Disclosure of utility model The present utility model aims to provide a jacking freight car which overcomes or at least partially solves the above-mentioned problems. In order to achieve the above purpose, the technical scheme of the utility model is specifically realized as follows: The utility model provides a jacking freight trolley, which comprises an AGV body, wherein a protective shell is arranged on the AGV body, a thread sleeve is inserted on the protective shell in a guiding way, the top end of the thread sleeve is rotatably connected with a supporting plate through a bearing, the top end of a supporting tray is connected with a roller conveying assembly, the lower part of the thread sleeve is connected with an adjusting screw rod, the thread sleeve is in meshed connection with the adjusting screw rod through threads, the adjusting screw rod is arranged in the protective shell, the bottom of the adjusting screw rod is rotatably connected with the AGV body through a bearing, a first servo motor is further arranged in the protective shell, the first servo motor is connected with the adjusting screw rod through a first driving gear and a first ring gear and drives the adjusting screw rod to rotate, the left part of the thread sleeve is provided with a second servo motor, and the second servo motor is connected with the supporting tray through a second driving gear and a second ring gear and drives the supporting tray to rotate. As a further scheme of the utility model, the protective shell is provided with a guide hole, and the thread bush is inserted into the guide hole and guided to move along the guide hole. As a further scheme of the utility model, a limiting hole is further formed in the protective shell, and the lower part of the second servo motor penetrates through the limiting hole. As a further scheme of the utility model, the first driving gear is sleeved and fixed on an output shaft at the lower side of the first servo motor, the first ring gear is sleeved and fixed on the adjusting screw rod, and the first ring gear is meshed and connected with the first driving gear through gear teeth. As a further scheme of the utility model, the second driving gear is sleeved and fixed on the output shaft at the upper side of the second servo motor, the second ring gear is sleeved and fixed on the supporting tray, and the second ring gear is meshed and connected with the second driving gear through gear teeth. The lifting freight trolley has the beneficial effects that the purpose of stably transporting cargoes through an AGV is achieved, the cargoes can be aligned with the cargoes, the cargoes can be stably taken down from a goods shelf, and the gravity center of the cargoes can be adjusted so as to ensure the stability and the safety of the cargoes in the transportation process, and the lifting freight trolley is simple to operate and high in automation degree.
