Automatic tensioning device of spring type drag chain

Technical Field

The utility model belongs to the technical field of the drag chain overspeed device tensioner, concretely relates to automatic overspeed device tensioner of spring drag chain.

Background

The chain conveyor uses a chain as a bearing and traction member to finish the conveying work of materials. The chain belongs to a flexible traction member and is characterized by strong bearing capacity and small elongation when bearing load; can pass through a chain wheel, a guide wheel, a pulley and a tail wheel with small straightness; it is very convenient to fix various conveying elements on the conveying device. It is the same as another 'flexible traction member and a conveyor belt' and requires a tensioning adjustment device, otherwise the conveyor cannot work normally. The tensioning device is therefore an indispensable essential component of the chain conveyor. The chain is usually arranged at the tail part of the conveyor and can be adjusted together with the tail wheel, after the chain is loaded into the conveyor, the chain is loose under the condition of not being tensioned and cannot normally work, the conveyor can normally run only if the chain obtains a certain pretensioning force (namely initial tension), and the tail wheel of the conveyor is usually a driven wheel and is rotated by the friction force between the tail wheel and the chain. The traction member can be tensioned properly, so that the degree of suspension can be reduced, and the friction between the traction member and the shell is reduced. The tensioning device with a certain automatic tensioning function can also be used for carrying out micro extension or contraction on the traction member caused by tension change. The existing device is often fixed insecure, the position of the pressing block is easy to deviate, the angle of the pressing block is fixed, tensioning operation can be carried out only at one position, and once the position is changed, the angle cannot be adjusted as required, so that the use of the device is influenced.
