Description

[Technical field]

[0001] The present invention relates to the technical field of building construction equipment, and more particularly to pile frames. [Background technology]

[0002] Pile frames are large machine tools that are indispensable in construction work, and all kinds of pile foundation construction tools such as pile driving and hole drilling must be mounted on pile frames to carry out construction work. Crawler pile frames are one of the various pile frames, and are moved to a different location by crawler travel, and are characterized by their flexibility and convenience. Crawler pile frames usually mainly consist of a chassis, a machine body, a column, an inclined support, and a power hydraulic system, etc., and since the column is long (usually 20 to 40 meters), when transporting the frame over a long distance, the mast must be tilted sideways relative to the column to remove it, and then the mast must be erected and installed again at the new construction site.

[0003] Currently, there are several types of crawler pile frames and their mounting methods:

[0004] As shown in Figure 1, the first type requires the assistance of a crane. When raising the mast, the hoist moves the pulley block to raise column 01 to 75 degrees, and the crane assists in hoisting the tilt support cylinder to the installation position, and then the tilt support cylinder pulls the column vertically.

[0005] As shown in Figure 2, the second type can use a set of cylinders to raise the mast when the height of the mast is small, and the column 01, the cylinder 02 and the body are hinged to a large triangle, and the verticality of the column is adjusted by contracting the cylinder. The pile frame used to raise the mast in this way must not have too high a column, and the support point is low and not very stable.

[0006] As shown in Figure 3, the third type does not require the assistance of a crane and employs the combined action of two sets of cylinders 02 to raise the mast. During the operation, the requirements for the synchronization of the mast-raising cylinders are particularly high, making the operation difficult.

[0007] As described above, how to provide a pile frame which does not require the assistance of a crane truck and allows for easy mast erection operation is a problem that must be urgently solved by those skilled in the art at present.
