Description

Technical Field

[0001] The utility model relates to the technical field of pile drivers, in particular to a ground wheel tube structure of a pile driver. Background Art

[0002] The walking structure of a pile driver is generally a pipe-type, crawler-type, or walking-type structure. It supports the upper part of the pile driver and performs the walking function. Since the soil in the south is mostly soft foundation, some construction sites require the pile driver to be light in weight. The walking-type and crawler-type structures are too heavy to enter the site, so the pipe-type structure is the only option. However, the existing pipe-type structure uses a ground wheel pipe to lay sleepers, which may cause the sleepers to sink and cannot be removed during construction, reducing the stability of the pile driver during construction. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a ground wheel tube structure of a pile driver, including a chassis, a pressure wheel member, a ground wheel tube and a base, the two sides of the chassis are fixedly connected with pressure wheel members, the pressure wheel member is provided with an arc groove adapted to the ground wheel tube, the base includes a U-shaped member and a bottom plate connected thereto, and the ground wheel tube is arranged between the pressure wheel member and the U-shaped member.

[0004] By adopting the above technical solution, the traditional single ground wheel tube structure is replaced by a combined structure of a base and a ground wheel tube, and the contact area between the chassis and the ground is increased through the base ground wheel tube to reduce the pressure of the pile driver on the foundation and improve the stability of the pile driver during walking and drilling.

[0005] The utility model is further configured that reinforcing ribs connected to the bottom plate are provided on both sides of the U-shaped member, and the reinforcing ribs are evenly distributed on the bottom plate in a straight line.

[0006] Furthermore, side walls are provided on both sides of the U-shaped part, the inner sides of the side walls are inclined surfaces, and the side walls are provided with rounded surfaces abutting against the ground wheel tube.

[0007] By adopting the above technical solution, a U-shaped part is welded on the base plate, and the connection strength between the two is improved by reinforcing ribs. The U-shaped part forms a trapezoidal groove that is wide at the top and narrow at the bottom through an inclined surface. When the ground wheel tube is placed on the base, the outer surface of the ground wheel tube is always tangent to the rounded surface.

[0008] The utility model is further configured such that the chassis is provided with a first steering support for rotationally connecting the column, and a second steering support for rotationally connecting the pull rod, the second steering support is arranged on both sides of the first steering support, and the first steering support and the second steering support are arranged directly above the ground wheel tube.

[0009] By adopting the above technical solution, the connection points between the column and the pull rod of the pile driver and the chassis are respectively the first steering support

[0010] The seat and the second steering support enable the force exerted by the column and the pull rod on the chassis to act directly on the ground wheel tube, avoiding bending deformation of the chassis due to long-term stress and maintaining the stability of the structure.

[0011] The utility model is further configured that an outer support frame is connected to one side of the chassis close to the first steering support, and the outer support frame is provided with support legs.

[0012] By adopting the above technical solution, an external support frame is bolted to one side of the chassis, and the support legs increase the contact area between the chassis and the ground. When the column is tilted towards the chassis, the center of gravity of the chassis is prevented from shifting and tipping over, thereby improving the stability of the chassis structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The structure of the base and the ground wheel tube combination replaces the traditional sleepers, and the base ground wheel tube increases the contact area between the chassis and the ground to reduce the pressure of the pile driver on the foundation and improve the stability of the pile driver during walking and drilling.
