Abstract

Abstract PURPOSE:To improve the efficiency by providing a packing mechanism, consisting of tamping bars, and a generating mechanism for driving the packing mechanism in a crawler shovel system excavator, and vibrating the tamping bar, while it is slightly opened and closed, so as to pack ballasts in a railroad line. CONSTITUTION:Front and rear members 2 are formed of transverse bars 4, tamping bars 1 fixed through a box unit to this transverse bar 4 and eccentric weight type vibrating member 8 provided in the box unit. Next the member 2 is rotatably supported to the lower end of a hanger member 3 through an arm piece 9 fixedly provided in the bar 4. Then an opening-closing mechanism of the member 2, consisting of a cylinder and link, is provided, while the member 3 is mounted to an arm of a shovel by a horizontal shaft 18. Further a generator B for driving the member 8 is mounted to the shovel. The bar 1 is sunk in ballasts, in a condition that a sleeper (b) is surrounded, to perform vibratory excitation while a little open-close swiveling. In this way, construction can be performed in a short time further uniformly with reduction or elimination of labor attained in ballast packing work.
