Description

Power and free type traction trolley for heavy ground

Technical Field

The utility model relates to a but be used for heavy ground long-pending formula traction table car of putting, in the surface coating line of mainly used fork truck balancing weight.

Background

With the continuous development of the modern coating industry towards the directions of high efficiency, automation and intellectualization, the surface coating production line of the forklift counterweight block quickly eliminates the backward production mode of spreading and manually transferring workpieces by point-to-point transfer of a forklift in the past, and instead adopts a continuous operation automatic production line. Because the weight of fork truck counter weight is big, and the shape is complicated various, among the intelligent coating line of present mainstream, the automation equipment that is used for the work piece to carry mainly adopts the conveyer of following two kinds of forms:

1. an overhead chain conveyor mode.

The loading trolley group is formed by the accumulating trolley group and the loading beam together, the workpiece is hung below the loading beam through a hanger, the workpiece is automatically conveyed to each process section of the production line through a hanging conveying chain, and the automatic accumulating function of the workpiece at any position in the production line is realized in each process section through the cooperation between the trolley group and a stopper. The conveying mode has high automation degree and high efficiency, and is particularly suitable for a production line with high requirements on continuous operation and capacity.

However, the forklift counterweight block has complex and various shapes, and the size and weight difference is often large, the suspension mode is complex to operate at an upper workpiece station and a lower workpiece station, and the safety risk of operators is large; secondly, the hanging conveying chain can cause the equipment main body to be higher in height, the reason that the equipment structure bears, the structural strength requirement is higher, the equipment investment is higher, and the equipment maintenance cost is higher.

2. Floor drag chain conveyor.

The workpiece is placed on the ground trolley through a forklift, the trolley is transferred between different operation stations mainly through pushing trolleys which are arranged on chains of a floor drag chain conveyor at equal intervals, each pushing trolley is provided with a ground trolley, the floor drag chain moves forwards in a stepping mode at equal intervals every time, and the pushing trolleys can push the ground trolleys to move forwards, so that the workpiece is automatically conveyed between different operation stations. The workpiece is only required to be forked on the trolley by the forklift at the workpiece loading and unloading stations, so that the safety risk of operators is low, and the operation is simple. And secondly, the overall height of the equipment is greatly reduced compared with that of a suspension chain conveyor, and the equipment does not need to bear the load of workpieces, so that the equipment investment is greatly reduced.

However, the conveying mode has relatively obvious defects, the trolleys are only arranged at equal intervals under the influence of the chain pushing head trolleys, and the distance between different process chamber bodies on a production line is often large in order to reduce the mutual interference among different processes; secondly, the trolley can only step at equal intervals when running forwards every time, and the efficiency is extremely low.
