SU1234520A1 - Arrangement for compacting soil - Google Patents

Description

The invention relates to building machines used to dynamically compact soils by dropping a large mass using serial cranes or other lifting means, and can be used in construction.

The purpose of the invention is to increase productivity.

FIG. 1 shows the device, a general view; in fig. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. 2

A dropable hammer 5 hangs on the crane hook with the help of a latch 11. At the same time, the cap 8 is mounted on the safety device 6, the ropes 4 are natu at the expense of the weight of loosely sagging ends. To drop the hammer, the machinist steals the lifting of the hook and the hammer begins to rise. When the latch 11 stops 10 seconds from the stop 13 and turns, the catcher 6 and cap 8 will be undocked. The hammer falls freely on the ground, compacting it (the surface of the ground is pre-planned). At the same time, the friction device 14 ensures constant tension of the ropes 4 during

On the boom of the crane 1, which is equipped with a boom cushioning system or a device providing gradual acceleration of the load, blocks 2 and 3 are located at its base and at the end. Tension by the ropes 4. The ropes, with their ends of the fasteners 4, when placing the load on the ground, are towards the discharged hammer 5 in such a way that the lower parts of the ropes have some free sag. On the drop hammer 5, a safety device 6 is installed, having a 2Q outer conical surface. On the load hook 7, for example, of a crane, a centering cap 8 is suspended, having an internal conical surface on which guide blocks 9 are mounted, spanning the ropes 4. On the safety device there is a collar 25 of the cage, the latch 10 engages, and the it automatically joins the center 11, which is pivotally mounted on the cap cap 8 and the safety device b. Next is ke 8. The latch lever is connected to the spring, the hammer is raised and the cycle repeats. 12. In the upper part of the boom there is a stop 13. The proposed device allows auto

The idle branches of the ropes 4 interact to mechanize the docking operation of the hammer with the friction device 14, thereby increasing the productivity of the free movement of the idle tires and eliminating manual labor.

it is provided with the weight of the lower sagging part of the ropes even with a certain unevenness of the soil. To dock the hammer with the cap 8, the driver lowers the hook with the cap hanging on it. In this case, blocks 9 move along tensioned ropes 4 as along guideways. This ensures accurate centering of the cap 8 relative to the catcher 6. Under the action of the weight of the cap and hook

branches of the ropes 4 down and braked upward movement.

The device works as follows.

To drop the hammer, the machinist steals the lifting of the hook and the hammer begins to rise. When the latch 11 stops up and stops 13, the catcher 6 and cap 8 will be uncoupled. The hammer falls freely onto the ground, compacting it (the ground surface is pre-planned). At the same time, the friction device 14 ensures constant tension of the ropes 4 during

free fall time. Tension of the ropes 4 when the load is placed on the ground of the cage triggers the latch 11, and it automatically joins the centering cap 8 and the safety device b. Next comes the rise of the hammer and the cycle repeats. The proposed device allows auto
