SU975904A1 - Apparatus for driving pile by pressing-in - Google Patents

Description

The invention relates to the construction and can be used for immersion in the soil of piles, pipes and other construction elements.

A device for diving piles with indentation, including a traverse carriage with an indentation mechanism installed on it, made in the form of a chain mechanism with a drive [11.

The disadvantage of this device is its complexity and low reliability.

It is also known a device for immersing piles with indentation, including a mast with a guide, on which a support plate with clamps, a head-cap and hydraulic cylinders are movably mounted [2 3..

The disadvantages of the known devices are the low efficiency of immersion, the need to use jacks of high power and the complexity of the design of the device.

• · The aim of the invention is to increase the efficiency of piling.

This goal is achieved by the fact that in the device for immersion in-. This includes a mast with a rail on which the stop2 is movably mounted.

naya plate with retainers head cover and hydraulic cylinders, thrust plate, made in the form of a carriage with articulated

with unequal arms mounted on it, some ends of which have the possibility of interaction with the headrest, while others are connected to the carriage by the damage of hydraulic cylinders and have stops interacting with retainers made self-jamming.

FIG. 1 shows a device for indentation of piles, total

. _ view of FIG. 2 is a view A of FIG. one.

The device consists of a base machine 1, a mast with a guide 2, in the lower part of which a power beam 3 is fixed with anchors 4. On the mast

along the guide 2, there is mounted a stop plate 5, made in the form of a movable carriage, on which the power cylinders 6 are movably mounted, unequal arms 7 with stops 8, and a cap 9 with a lift

"loop 10 and self-wedging clamps 11 with return springs 12.

Piling Device

four

anchoring by means of anchors 4. In a known manner, the pile is loaded into the headgear 9. By supplying hydraulic fluid to the piston cavity of the power hydraulic cylinders b using unequal arms 7 through the head 5, the pile 8 is pressed into the ground and the stops 8 come out of engagement with the shanks 'self-clamping retainers 11, ensuring reliable fixation of the thrust plate No. 5 relative to the guide 2. The pile is pressed in until the rods are fully released from the hydraulic cylinders b, then the fluid is fed into the rod shaft They switch the movement of the hydraulic cylinder b to the reverse stroke, while the stops 8 act on the shanks of the self-clamping grippers 11, forcibly opening them and ensuring the free movement of the support plate 5 down to the contact of the unequal arms 7 with the Headrest 9. Then the immersion cycle repeats. After the pile has been immersed to the required depth, with the self-seam grips 11 opened by the lifting winch of the base machine 1 with the help of the lifting loop 10, production-. they lead the lifting of the head cover 9 together with the support plate 5 to the initial position • The proposed device allows to significantly increase the force of immersion and to refuse from manual operations for switching clips when lifting the support plate.

Claims (1)

Claim A device for pushing in piles, including a mast with a guide, on which a stop plate with clamps is movably mounted, a cap and hydraulic cylinders, characterized in that, in order to improve the efficiency of the dip, the stop plate is made 15 in the form of a carriage with unequal arm levers hinged on it, one ends of which have the ability to interact with the head and others, are connected to the ^carriage by means of hydraulic cylinders and have stops interacting with retainers made self-jamming.
