Description

Technical Field

[0001] The invention relates to the technical field of intelligent conveying systems, and in particular to a ground double-track trolley which is convenient for turning. Background Art

[0002] The existing aerial double-track trolley turning technology is relatively mature, capable of fast turning, driven by a single motor, with a simple design structure and low production cost. However, there are not many companies in China that can give a satisfactory answer to the development of ground double-track trolleys. They also face a series of problems such as the track, running wheels, guide wheel design or drive components are very complicated, resulting in a slow turning speed, high production cost, and light rated load. In order to solve these problems, we decided to invent a new type of ground double-track trolley after in-depth discussion and research. It only needs one set of motor drive to achieve turning and even continuous curvature turning, and it has strong load-bearing capacity, fast turning speed, simple structure and relatively low cost.

The main vehicle 1 and the second auxiliary vehicle 3 are respectively fixed to two opposite corners of the bearing member 5, and the first trolley and the third trolley are respectively rotatably connected to the other two corners of the bearing member 5. The rotatable connection is specifically realized by the following structure: Figure 2 , Figure 3 and Figure 4As shown, the rotating mechanism includes a circular slide groove 62, a fixed seat 63 arranged in the middle of the circular slide groove 62, and a turntable 61. A reversing wheel 64 is provided below the turntable 61, and the reversing wheel 64 is clamped in the circular slide groove 62. The turntable 61 is fixed above the fixed seat 63.
