The invention fires on a pile apparatus for working and installation movements of the H1-D2:

Izzesgen pile anparag dredger, which guides; a pile with a longitudinal ogversgiy, power cylinders with loaded spring cylinders and ring clamps.

The purpose of the invention is the simplification of the CEC; as well as reducing the size and weight of the device.

This goal is achieved by the fact that coaxial holes are made in the grips, in which fingers are movably mounted, connected by means of cross-arms with spring-loaded cylinder plungers fixed on the grips parallel to the fingers.

On the FKG, 1 the proposed apparatus is shown, on the FKG, 2 is a section along A-A in FIG. one

The pile apparatus includes a working gripper 1 and an auxiliary gripper 2, which encloses the pile 3. The pile is movably mounted in the guide 4 and has keys in the guide grooves. Each grip is made in the form of a ring 5, with the ring

Also, the capture of compound 1eno with gndrotsil: hadron 6 of double action. The lid of the hydraulic cylinder 7 with the two plungers 8, which are pressed against the springs 9, 8, are rigidly connected with the help of the traverse 10 about the fingers: 11, which are movably mounted in the guides 12. The pile has a longitudinal row of holes for the fingers 11, which are located with a certain pitch. On the working grab 1, reinforced loaded springs 13.

The device provides, in the operating mode, raising and decelerating the pile, as well as the installation hoist {or lowering the pile within its entire length. An axial force to the pile is transmitted from the cylinder 6 through the working pick ring, the guides 12 and the fingers 11.

In the operating mode, the pile is moved by the cylinder rod 6 through the working gripper 1 coupled to the pile. The auxiliary gripper 2 in this case moves with the pile, with which it is engaged, at a distance from the working gripper 1, equal to the stroke of the hydraulic cylinder 6. The pile is set in the following sequence. Worker grip 1, with deeper soil development, engages with the pile near the upper end of the pile, and with less depth development, closer to the lower end of the pile. Changing the place of engagement of the working gripper 1 with the pile (interception) is carried out with the help of auxiliary gripper 2. When switching to a deeper development of the soil, the auxiliary gripper 2 coupled to the pile rests on guide 4, while the working gripper 1 lowers until it stops against the hydraulic cylinder 6. After that, the working gripper 1 disengages from the pile (by supplying working fluid into its plunger hydraulic cylinder 7) and is raised by the hydraulic cylinder 6 to the required height, a multiple of the pitch of the holes in the pile and engages with it (by discharging the working fluid from its plunger hydraulic cylinder 7). Then, the auxiliary gripper disengages from the pile and engages with it after lowering the pile to the stop on the hydro-cylinder 6. When going to a shallower excavation depth, the auxiliary gripper 2 disengages from the pile, the pile is raised by the hydraulic cylinder 6 to the required height, which is a multiple of the hole hole in the pile, After this, the gripper 2 engages with the pile, and the gripper 1 disengages from the pile, drops to 6, and then spelled it to the hydraulic cylinder with the pile. The formula was invented by a dredger pile machine, including guides, a pile with a longitudinal row of holes, power cylinders with spring-loaded plungers and ring clamps, characterized in that, in order to simplify the design, reduce the size and weight of the device, coaxial holes are made in the hooks in which the fingers are movably mounted, connected by means of cross-arms with spring-loaded cylinder plungers, fixed on the grippers parallel to the fingers. ig. one
