Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is side view of the present invention;
Fig. 2 is front view of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of reciprocating engine embodiment with compensatory control provided by the invention, comprise crane 1, the base of crane 1 is provided with reducing motor 2, crane 1 is provided with corresponding drive sprocket 3 and driven sprocket 4, the output shaft 21 of reducing motor 2 connects drive sprocket 3, drive sprocket 3 is connected by driving chain 5 with driven sprocket 4, crane is provided with the support 6 that dusts, the support 6 connection for transmission chain 5 being driven by driving chain 5 of dusting moves up and down along crane 1, and the support 6 that dusts is provided with spray gun 7.
Further, crane 1 two ends are respectively arranged with the limit switch 11,12 limiting support 6 displacement of dusting, when the support 6 that dusts arrives crane 1 two ends; limit switch 11,12 can be triggered, send control signal, reciprocating engine can be made to shut down; or reducing motor 2 is reversed, support 6 oppositely movement of dusting.Dust the balancing weight 61 support 6 is provided with for controlling its balance; Dust and be also provided with the tensioning spring 62 of cushioning effect in support 6, improve the service life of the support 6 that dusts.
