Abstract

The invention relates to a pile driver, which mainly comprises a winch, a traction device and a rammer, wherein when the pile driver lifts the rammer upwards and the rammer falls down to pile, the winch, the traction device and the rammer are connected without being separated to carry out pile driving operation, and the hammer head of the rammer is a conical head.

Description

Pile driver

Technical Field

The invention relates to the field of piling machinery, in particular to a non-unhooking type piling machine.

Background

In the existing unhooking type dynamic compactor or pile driver, when in operation, a winch controls a steel wire rope to lift a rammer to a certain height, a unhooking device is used for separating the rammer from the steel wire rope, and the rammer falls freely to perform dynamic compaction or pile driving. In the operation process, after the rammer is lifted to a certain height, the rammer is unhooked and separated from the rammer, and after the rammer falls down, the hook or the manual auxiliary hook is re-hooked, so that the operation process is relatively complicated, the construction efficiency is relatively low, and potential safety hazards also exist. Meanwhile, the operation depth of the existing unhooking type dynamic compaction machine or pile driver is limited, when the rammer falls into a deeper foundation hole, the rammer is prone to being inclined in the hole, the hook is not easy to operate, phenomena that the rammer cannot be found due to the fact that the hammer is sucked and buried easily, the rammer cannot be hung again, the piling construction progress is influenced, economic loss can be caused, and safety problems can be caused.

In summary, it is an urgent need to solve the above problems by those skilled in the art to improve the efficiency of pile driving, to expand the range of pile driving depth operation of the pile driver, and to enable the pile driver to perform pile driving operation on both shallow and deep ground.

Disclosure of Invention

In order to solve the above technical problems, the present invention provides a pile driver, which not only expands the pile depth range of the pile driver, so that the pile driver can pile both the shallow layer and the deep layer of the foundation, but also can improve the pile driving efficiency.

In order to achieve the purpose, the invention provides a pile driver, which mainly comprises a winch, a traction device and a rammer, and is characterized in that: when the pile driver upwards promotes the ram and the ram whereabouts pile, hoist engine, draw gear are connected with the ram and do not throw off and carry out the pile driving operation, the ram tup is the conical head, the appearance of conical head is circular, triangle-shaped, rhombus, polygon, parabola shape, toper or olive shape, the bottom surface of ram tup is sharp end, arc end or flat.

Preferably, the winch is a manual sliding type winch, an electric sliding type winch, a hydraulic sliding type winch or a belt-loaded quick-release winch.

Preferably, when the pile driver is used for piling, the winch is a single winch or a double winch or a multiple winch.

Preferably, the rammer head is a conical head, and the side surface of the conical head is smooth or is provided with a hammer blade or a blade.

Preferably, the traction device is a steel wire rope, a chain, a rigging or a connection combination of two or three of the steel wire rope, the chain and the rigging.

Preferably, the pile driver is further provided with a traveling device, and the traveling device is a crawler-type traveling device.

The invention has the beneficial effects that: when the pile driver lifts the rammer upwards and the rammer falls to pile, the winch and the traction device are connected with the rammer without disengaging for piling, so that the range of the piling depth construction work of the pile driver is expanded, the pile driver can pile on a shallow foundation soil layer and can also complete the piling work on a deep foundation, the construction efficiency of the pile driver is improved, and the pile driver is more suitable for various working condition requirements.

Drawings

The figure is a schematic view of a pile driver of the present invention.

It should be understood that the drawings are not necessarily to scale, showing the particular construction of the invention, and that illustrative features in the drawings, which are used to illustrate certain principles of the invention, may also be somewhat simplified. Specific design features of the invention disclosed herein, including, for example, specific dimensions, orientations, locations, and configurations, will be determined in part by the particular intended application and use environment.

Detailed Description

The pile driver of the invention mainly comprises a pile driver platform 1, a pile frame 2, a rammer 3, a pulley 4, a traction device 5, a winch 6, a walking device 7 and the like.

The pile machine platform 1 provides mounting support for other components, and other components such as the winch 6 and the pile frame 2 can be mounted on the pile machine platform 1. Alternatively, a crawler-type walking device 7 can be arranged below the pile driver platform 1 to facilitate the movement of the pile driver.

The traction device 5, alternatively, the traction device 5 may be a wire rope, a chain, a rigging, or a combination of two or three of them. Alternatively, the steel cord may be single, double or multiple.

Pulley 4, which pulley 4 may alternatively comprise a pulley provided on pile frame 2 and a pulley provided on pile machine platform 1, pulley 4 may cause the direction of traction means 5 to change.

The rammer 3, as an option, the rammer 3 can include the tup, the tup can be the conical head, the appearance of conical head can be for circular, triangle-shaped, rhombus, polygon, parabola, toper or olive shape, the bottom surface of tup can be sharp bottom, arc bottom or flat bottom, the conical head side can be for level and smooth or be provided with the hammer blade or be provided with the cutting edge.

The winch 6 can be a manual sliding type winch or an electric sliding type winch or a hydraulic sliding type winch or a belt-loaded quick-release winch as an option. Alternatively, the winch 6 may have a clutch for restraining or releasing the restraint of the winding drum of the winch 6, the clutch of the winch 6 restrains the winding drum when the rammer 3 is lifted, the wire rope is wound on the winding drum of the winch 6 by rotating, the winding drum of the winch 6 releases the restraint by the clutch when the rammer 3 is lowered, and the rammer 3 drives the traction device 5 to fall together under the action of its own weight to perform piling. Alternatively, hoist 6 may be a single hoist or a double or multiple hoists.

The above embodiments are provided to illustrate the principle of the present invention and its efficacy, but the present invention is not limited to the above embodiments. Those skilled in the art will recognize that changes may be made in the above embodiments without departing from the spirit and scope of the invention, which is set forth in the following claims. Therefore, the scope of the present invention should be covered by the appended claims.
