The specific embodiment

The scraper plate machine local structure front view that Fig. 1 provides for the utility model embodiment, Fig. 2 is the birds-eye view of Fig. 1, the utility model embodiment provides a kind of scraper plate machine; Comprise aircraft tail shelf 1 and tail wheel 4; Aircraft tail shelf 1 is provided with open slot, and tail wheel 4 passes this open slot and is fixed on the aircraft tail shelf 1, wherein; This scraper plate machine also includes the linear actuator 2 and passing seat 3 that is fixedly installed on the aircraft tail shelf; An end of passing seat 3 is captiveed joint with linear actuator 2, and the body of passing seat 3 is taken turns 4 with tail and captiveed joint, and is used under the drive of linear actuator 2 the promotion tail and takes turns 4 and move with respect to aircraft tail shelf 1; Pass seat 3 and be provided with guide rail towards aircraft tail shelf 1 one sides, said aircraft tail shelf 1 is provided with guide groove 6, and said guide groove 6 matches with said guide rail, realizes passing 3 relatively moving with respect to aircraft tail shelf 1.

When scraper chain was in normal working, tail wheel 4 was to be fixed on the aircraft tail shelf 1 through bolt or other connecting element, after finding that scraper chain is lax; Connecting element is unclamped, open linear actuator 2, promote to pass seat 3; Pass seat 3 and drive tail wheel 4 along guide groove 6 side travels, tension chain is when chain tension to suitable degree; Through fastener tail wheel 4 is fastened on the aircraft tail shelf 1 again, thereby has realized the tensioning of chain.The scraper plate machine that the utility model embodiment provides drives the passing seat through the linear actuator that is provided with on the aircraft tail shelf and moves, thereby it is mobile to promote the tail wheel, has realized the purpose of chain tension, and is simple in structure, easy to operate.

Passing holder structure scheme drawing in the scraper plate machine that Fig. 3 provides for the utility model embodiment; Please be simultaneously with reference to Fig. 1; Preferably, on the body 31 of passing seat 3, offer mating holes 32, be used for cooperating socket with tail wheel 4; Simultaneously on body 31, also offer a plurality of bolts hole 33, passing seat 3 is fixed on the aircraft tail shelf 1 thereby can match with bolt.
