SU376128A1 - VIBRATOR FOR DIPPING IN GROUND PILED - Google Patents

Description

one

The invention relates to the field of construction and can be used in the construction of foundations for the sinking or removal of piles.

Devices for immersing or extracting piles, i.e. Vibrators, are known, including housing, drive, driving and driven shafts with unbalances.

. However, these devices do not provide the ability to control the magnitude of the disturbing force by smoothly moving from harmonic to impulsive disturbance during operation.

To achieve this goal, the driven shafts of the vibrator are made with the possibility of vertical movement relative to the driving shafts and are fixed to a base plate installed with the possibility of moving in wedge guides mounted in its own turn in the body with the possibility of horizontal movement, each of leading and following shaft is connected by means of a rocker mechanism made with a crank and a slider mounted for movement along a rod, one end of which is fixed on the driven shaft, and and the other end is mounted an eccentric weight.

FIG. 1 shows the proposed vibrator, a general view; in fig. 2 - the same section

on aa in fig. one; in fig. 3 is the same; the section along BB in FIG. 2

The vibrator includes electric motors /, klinoremennye transmission 2, body 3, leading

shafts 4, brakes 5, crush-in 6 with fingers 7, sliders 8, unbalances 9, connecting rods 10, unbalanced shafts //, supports of mobile debalance shafts 12, support plate 13, having the possibility of vertical displacement

in the wedge guides 14, which are capable of moving in the guides 15 along the base of the housing 16 with the help of a double-cut screw 17, a gearbox 18 and an electric motor 19. To ensure

rigid fixation of unbalance shafts; their bodies have stops 20 fixed by guides 21.

The vibrator works as follows. The rotation from the electric motors / by means of the timing gears 2, the scraper 5 is transmitted to the drive shafts 4 with the cranks 6 rigidly mounted on them. Rotating the cranks 6 with the help of the fingers 7 and the sliders 8 moving in the connecting rods 10, leads the rods and fixed on they unbalance in rotational motion. The balances located on different shafts, rotating in pairs towards each other, create a disturbing force of directional action. In the event that the axes are unbalanced

// and the leading 4 shafts are the same, there is a harmonic perturbation. When the distance between the axes of the drive and unbalance shafts is changed by the value of ± e, a pulsed perturbation takes place. The change in the position of the axes of the unbalance shafts relative to the axes of the drive shafts is carried out as follows.

The motor 19 through the gearbox 18 causes a rotational screw, which pushes and pushes the wedge guides 14, displacing in the vertical plane the base plate 13 with the unbalance shafts 12 fixed to it 12. The eccentricity e is adjusted continuously in the process, which ensures possibility of automating the building of the vibrator to the desired mode
