Heavy frictional combined conveying line

Abstract

The invention discloses a heavy frictional combined conveying line which is characterized by comprising a rail, a double-wheel driving device and / or a single-wheel driving device, and a dolly. The double-wheel driving device comprises motors, driving wheels, friction plates and a spring compressing device; the driving friction wheels are installed on driving shafts of the motors; friction objects are cast or installed at outer parts of the driving friction wheels; a gap is formed between the friction plates on the driving wheels; bases of the motors rotating in opposite directions are connected on a steel structure by using a base shaft and a bearing respectively; and the spring compressing device is connected with the bases of the two motors; centers of the base shaft of one motor and a motor driving shaft are not in a same line; the thickness of a dolly friction plate is slightly greater than the width of the gap; and the frictional force is adjusted by the spring compressing device. The heavy frictional combined conveying line has the advantages that firstly, work pieces carried by the conveying line are mainly carried by the rail, and the driving device provides the frictional force only; secondly, the conveying line can have a power and free function, the frictional force is easy to adjust, and the friction plates are easy to change and convenient to maintain; and thirdly, the conveying line comprises an upper layer and a lower layer, thereby being convenient for automatic production.

Description

technical field [0001] The invention relates to a heavy-duty friction combined conveying line used in the production of engineering machinery, belonging to the technical field of conveying machinery. Background technique [0002] The production of existing engineering machinery is generally to use driving to cooperate with forklift and shelf to produce. Set up several work stations in the factory. After the relevant operations are completed at this work station, the parts are placed on the shelf with a crane, and then the forklift truck transports the shelf to the next work station. Such a production method is relatively primitive and the production efficiency is low. With the vigorous development of domestic infrastructure construction, construction machinery has developed rapidly, especially the production of excavators has been unable to keep up with market demand. [0003] Since the excavator is gradually developing into a large excavator, its weight is also quite larg...

AI Technical Summary

Problems solved by technology

[0003] As the excavator gradually develops into a large excavator, its weight is also quite large, reaching a maximum of more than 40 tons. The maximum weight that the existing ground conveyor line can carry is usually only 4 tons, which is far from this and cannot meet the requirements.
