Description

technical field [0001] The invention belongs to the technical field of logistics equipment machinery, and in particular relates to a device for driving, turning and changing tracks of a rail-type transport vehicle. Background technique [0002] At present, the existing rail material handling vehicles in the domestic automated logistics system are: linear reciprocating shuttle vehicles, monorail circular shuttle vehicles, and monorail circular air shuttle vehicles. The linear reciprocating shuttle car is driven by a single motor, and travels in a straight line on the double-row track, without steering and track changing functions. The linear reciprocating shuttle car can exert high efficiency for simple linear transportation due to its reciprocating linear travel. However, it cannot meet the handling requirements of multiple vehicles and complex paths in the system. The monorail circular shuttle car is driven by dual motors, runs circularly along the single row of tracks, a...

Problems solved by technology

Since each turnout needs to be equipped with a switch mechanism, the complexity of the track system is increased, which is not conducive to the expansion and change of the track system

[0003] In addition, there is another rail-type transport vehicle that realizes the driving, steering, and track-changing functions of the transport vehicle on the double-row track by controlling the speed difference between the two motors. Due to errors in the production and installation of the track, the theoretical radius calculated by the control system is different from the actual radius. There is an inevitable deviation in the radius of the track, and the speed matching of the two motors lacks an absolute reference basis, so the control is difficult and the mechanical wear is large. Using two sets of servo systems to control the two motors not only increases the manufacturing cost, but also increases the cost of the truck. The self-weight also increases accordingly, and the economy of use is not optimized enough, and it is difficult to meet the requirements of high-speed driving and large-flow handling.
