SU1703607A1 - Outrigger for hoisting-and-conveying machinery - Google Patents

Abstract

This invention relates to outrigger hoisting machines. The purpose of the invention is to improve performance. The outrigger comprises a jack 3 with a stem extension device installed with the ability to interact with its support point 6 with the support plate 7 of the support plate 8, a mechanism for rotating the support plate 8 including a horizontal shaft mounted on the rod with a gear wheel on which the levers 12 are rigidly fixed, pivotally connected to the base plate 8, and additional levers 13 pivotally connected to the latter and the stem 13. The stem is hollow, its extension device is a nut fixed in the upper part of the stem; to cooperate with it and in positioning vertically a hollow stem screw rotatably mounted in the housing of the jack 3, two motor and coaxially installed with their shafts lenny and associated with their housings and the casing jack planetary gear. The device is applicable to the operation of the machine on weak soils, with a deep track. 2 hp ff, 10 ill. AND

Claims (3)

Claim 1. An outrigger of a hoisting-and-transport machine, comprising a jack rigidly fixed to the frame with its body and a device for extending its rod, mounted with the possibility of interaction of its support heel with the thrust bearing of the base plate, and a rotation mechanism of the latter, including a horizontal shaft with gear mounted on the rod, on which levers are rigidly fixed, pivotally connected to the base plate, and additional levers pivotally connected to the latter and to the rod, characterized in that, in order to improve operational characteristics, the rod is hollow, the device for its extension includes a nut fixed in the upper part of the rod, installed with the possibility of interaction with it and placing in the rod a vertical hollow screw mounted for rotation in the jack body, two electric motors mounted coaxial with their output shafts and a planetary gearbox connected to their bodies and the jack body by its epicycle, the sun gear shaft of which is connected to the output shaft of the first electric motor by means of a connecting device the carrier, and the carrier is connected to the output shaft of the second electric motor and kinematically connected with the specified screw, the rotation mechanism of the base plate includes a vertical worm mounted in the stem with the possibility of interaction with the gear of its horizontal shaft, a disk clutch connected to it by its first disk, connected to it the last disk a hollow rod installed with the possibility of vertical movement in the specified screw, connected with its upper part and placed in it a rod, spring-loaded relative to the top parts of the latter and a sleeve mounted on it with the possibility of limited vertical movement, mounted with the possibility of interaction with its lower end with the upper end of the specified rod. 2. The outrigger according to claim 1, characterized in that said connecting device includes a double-acting freewheel coupled with a fork to said sun gear shaft and kinematically coupled with its last ferrule yoke, a freewheel, the sprocket of which is rigidly connected to the sprocket the first coupling, and the cage - with the output shaft of the first electric motor. 3. The outrigger according to claims 1 and 2, which is the only one. that the rotation mechanism of the base plate includes an additional double-acting freewheel. FIG. 7 Fig 8 1703507 Fig. U
