Description

Rail type guide vehicle Technical Field The application relates to the technical field of article handling equipment, in particular to a track type guide vehicle. Background In modern warehouse logistics systems and automatic production lines, efficient and accurate material transportation from an initial place to a target place is a key link for ensuring smooth operation of an overall operation flow. With the continuous expansion of industrial scale and the continuous rise of labor cost, the traditional manual handling-dependent mode has difficulty in meeting the requirements of high-efficiency and high-strength production and logistics. For this reason, the use of rail guided vehicles for material transport is an effective solution. The equipment can automatically run along the preset track, so that the pressure of manual carrying is obviously reduced, the material circulation efficiency is improved, the operation cost is reduced, and the intelligent and automatic management of the whole logistics system is realized. The rail guided vehicles generally comprise a chassis structure, on which a carrier or platform for carrying the material is arranged, under which a wheel assembly is arranged, which is matched to the rail. The wheels can travel along the track paved on the ground under the drive of the motor, so that the whole guide vehicle is driven to move according to a set path, and the fixed-point transportation task of the materials is completed. The equipment has simple structure and stable operation, is suitable for conveying materials in a fixed route in a factory or between warehouses, and has been widely applied in a plurality of industries. However, existing rail guided vehicles still have certain technical drawbacks, particularly when dealing with non-linear paths. Most current guided vehicles are only well adapted to straight track and are limited in application in complex paths requiring turns. When the guide vehicle carries the weight to pass through the curve, the vehicle body can generate larger transverse force in the original travelling direction due to the inertia effect, which puts higher requirements on the cooperation between the steering wheels and the track. The existing wheel structure cannot adjust the advancing direction in advance according to the track trend, so that derailment risk is very easy to occur after the wheels are subjected to inertia of a vehicle body in the steering process, and the running safety and stability of equipment are further affected. Therefore, how to improve the steering structure of the track-type guided vehicle, so that the track-type guided vehicle can adapt to a curve path and effectively reduce the derailment probability, has become an important research direction for improving the application range and technical performance of the track-type guided vehicle.
