Description

Suspension chain conveying device Technical Field The utility model relates to the technical field of workpiece processing equipment, in particular to a suspension chain conveying device. Background The suspension chain workpiece cleaning system generally comprises a suspension chain, a suspension chain conveying device and a plurality of workpiece processing stations, wherein the suspension chain is used for suspending workpieces (such as flywheel shells, automobile brake pads, equipment parts and the like), and the suspension chain conveying device is used for driving the suspension chain and the workpieces to sequentially pass through different workpiece processing stations so as to realize the processing (such as cleaning, drying and the like) of the workpieces. Existing catenary chain conveyors typically include a chain and a sprocket that is coupled to a work piece catenary chain and is in meshed transmission with the chain to effect conveyance of the catenary chain and work piece. However, in the existing suspension chain conveying device, the chain is usually directly installed in the track frame, in order to reduce the installation difficulty, the size of the chain is usually slightly larger than that of the track frame, so that the chain is excessively loosened after being installed in the track frame, and the transmission stability of the chain and the chain wheel is further affected. Meanwhile, in the long-term running process, acting force between the chain and the chain wheel also easily causes loosening of the chain, and further influences the transmission stability of the chain and the chain wheel. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a suspension chain conveying device. In order to achieve the above purpose, the utility model adopts the following technical scheme: A suspension chain conveying device comprises a main frame, an annular chain and an annular frame for mounting the annular chain; the annular frame comprises a first installation frame and a second installation frame; The first installation frame is fixedly installed on the main frame, and the second installation frame is slidably installed at one end of the first installation frame and is enclosed with the second installation frame to form the annular frame; The chain tensioning assembly is capable of applying a force to the second mounting frame away from the first mounting frame.
