Description

The invention relates to foundation building and can be used in vibratory pickups for sinking piles and pile shells. A vibratory pile driver is known, which includes a housing, an actuator, several groups of unbalances and a mechanism for changing the total static moment in the form of a differential, the debalans obtaining rotation through the differential by chain transmissions, and changing the static torque by rotating the differential case. The disadvantage of this vibrator is the presence of long communications in the form of asterisks and chains and the need to rotate the casing of the differential, which increases the size and weight of the vibrator and reduces reliability. A vibratory pile driver is known, comprising a housing, an actuator, groups of pairs of unbalances mounted on shafts interconnected by a system of gears, and a device for changing the total static moment. a vibratory driver, made in the form of a planetary gear mechanism, in which the central gear wheel and the carrier are connected to the de balances, and the gear wheel, along which the starlets roll around, with the mechanism of its rotation. A disadvantage of the known vibrator is that the gear on which the satellites are mounted is installed on the same axis with the central gear wheel, which necessitates the use of two groups of satellites and leads to an increased speed of their rotation and, consequently, to increased wear on them. the central gear forest and the carrier are not placed on the shaft with unbalances, but located on an additional axis located between the two groups of shafts with unbalances, which also leads to lengthening of the kinematic chains and ozhneniyu design. . The aim of the invention is to simplify the design and increase the reliability of the vibrator. The goal is achieved by the fact that in a vibratory driver, including a housing, an actuator, groups of unbalances installed in shafts connected in pairs, connected with the system, are wired, and a device for changing the total static moment of the vibrating engine, implemented in the form of a gear planetary mechanism, which has a central gear the wheel and the carrier are connected with unbalances, and the gear, along which the satellites run around, with its turning mechanism, the central gear wheel is fixed on one of the unbalanced shafts on which m installed with the possibility of rotation additional gear. connected to the carrier and meshing with the gear mounted on another shaft with unbalances, and the gear on which the satellites run in is made with internal teeth. The drawing shows a diagram of the vibrator. In the case of the vibrator, groups of two unbalances 2 and 3 are installed in pairs, kinematically connected with each other by gears 4, 5 and 6, 7. The unbalance groups 2 and 3 are driven from electric motor 8 through gears 9 and 10 - .. mentor vibrator, made in the form of a gear planetary mechanism, consisting of additional gear 11, connected to the planet carrier 12, seated freely on the shaft 13, satellites 14, rotating on the axis x 15, carrier 12, the central gear 16, rigid about connected with. shaft 13 and gear 17, along which the satellites 14 are driven. Gear 17 has its own drive, made, for example, in the form of a worm gear 18 with an electric motor 19, Gear 10 is rigidly connected to the shaft 20 of the unbalance gear 2. The vibro-loader works as follows. When the motor 8 is turned on, gears 9, 10, and 4 receive rotational unbalances 2, and gears planetary gear and gears 6, 7 receive unbalances 3. If motor 19 is not turned on, gear 17 is stationary, while the gear ratio between unbalances 2 and unbalance 3 equals one. If the electric motor 19
