Description

The utility model relates to pile drivers designed for driving piles.

Piling installations of various designs are known, including a base machine - an excavator, a crane or a truck, a pile driver mast with a pile driving control system, a pile driving hammer. When placed on the base excavator, the pile mast is flexibly attached using a pantograph, a triangle with a frame, or a rigid bracket, mounted instead of a bucket and a handle. There are options when only the handle and bucket are removed, the boom itself is not dismantled. When placed on a crawler crane, hydraulic pile grips are added to reduce the time of guiding the pile to the driving point. When placing the installation on a truck, it is provided for its movement on its own on public roads [1].

The disadvantage of piling installations is the complexity of the design, the need to re-equip the base machine, when transported on semi-trailers, the dismantling of standard equipment is required, and low productivity when driving piles.

Known copra installation containing a base machine (chassis) with a turntable, pivotally mounted on her boom with a carriage on the head, movably connected to the last mast, having guides in which the percussion mechanism is installed, the carriage with the drive of its movement and a fracturing device made with base fifth. In order to increase labor productivity and work safety, the mast is equipped with additional guides located in its lower part, along the side surfaces, in which the carriage of the fracturing device is installed, and the drive for its movement is made in the form of a power cylinder installed parallel to the mast on the side opposite to the movement of the shock mechanism, while the body of the power cylinder is connected to the mast, and the rod to the carriage, made with a window in which the heel of the breaking device is installed with the possibility of vertical movement [2].

The disadvantage of a pile driver is the complexity of the design.

Known pile driver SP-49D, designed for pile driving, lifting, moving and holding the pile driver on the mast, pulling, lifting and installing the pile under the pile driver, at the point of driving and in the desired position (inclined or vertical), extending the mast with the pile driver and the raised pile, for aiming at the point of driving, containing a T10MB tractor on caterpillar tracks, converted for a hinged part, a hammer, a head and a hinged part - pile equipment. The hinged part consists of a movable frame, hydraulic equipment, a carrier frame, a side brace, hydropolyspasts, a rear brace, a mast, a head, a pile arrow, an emphasis for piles, a block for pulling piles, and a device for lifting a hammer. The copra is controlled from the tractor cab. Power drive - hydraulic. As a pile driver, rod (SP5, SP6 VM), tubular (SP 75A, SP76A) diesel hammers can be hung on the pile driver, as well as, after completion of the pile driver, the hydraulic hammer SP7G [3].

The disadvantage of the copra is the high complexity of the work associated with the absence of a turntable in its design.

As a prototype, a pile driver was adopted, containing a base machine (chassis) with a turntable, an arrow hinged on it with a carriage on the head, movably connected to the last mast, having guides in which an impact mechanism is installed, a carriage with a drive for its movement and a breaking device made with a support heel. In order to increase labor productivity and work safety, the mast is equipped with additional guides located in its lower part, along the side surfaces, in which the carriage of the fracturing device is installed, and the drive for its movement is made in the form of a power cylinder installed parallel to the mast on the side opposite to the movement of the shock mechanism, while the body of the power cylinder is connected to the mast, and the rod to the carriage, made with a window in which the heel of the breaking device is installed with the possibility of vertical movement [2].

The disadvantage of a pile driver is the complexity of the design.

The utility model is based on the task of improving the design by optimizing the load on the base chassis by moving its engine outside the running gear, by reducing the overall height and overall length of the copra in order to ensure the convenience of transporting the copra on a heavy truck semi-trailer in a height dimension of up to 4 0 m on public roads by folding sections of the pile mast, turning the hammer on the pile mast from the transport position to the working position, without additional re-equipment and technological operations, as well as improving performance when driving piles by providing a longitudinal shift of the turntable with the pile mast and impact mechanism.

The technical result of the claimed utility model is an improvement in design, an increase in operational characteristics and its reliability.

The technical result is achieved by the fact that the pile driving caterpillar pile driver contains a base chassis, a turntable, to which a pile mast with guides, an impact mechanism and a hydraulic cylinder is fixed through a hinge, the base chassis is made in the form of a tractor caterpillar cart, the engine is located outside it on a remote platform, the turntable is made with the possibility of longitudinal shift relative to the base chassis, the rotation of the impact mechanism relative to the vertical axis of symmetry of the pile mast at an angle equal to 90 degrees is carried out using a swivel joint, the pile mast consists of sections interconnected by a hinge and a latch, two sections of the pile mast made folding, folding.

On the turntable there is a counterweight, an operator's cabin, a winch for pulling and installing piles, a winch for lifting and lowering the percussion mechanism.

The impact mechanism is made in the form of a hammer, the tractor caterpillar truck is made with a hydrostatic transmission.

The turntable with a pile mast, an impact mechanism and a hydraulic cylinder is designed to be mounted on a vehicle chassis with at least three axles.

Thus, the claimed implementation of the pile driving caterpillar pile driver provides an improvement in the design, redistribution of loads on the caterpillar bogie, reduced labor costs for bringing the pile driver to the working position, increasing operational characteristics and its reliability.
