Description

Technical Field

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

[0002] Pile frames are essential large-scale machine tools in construction projects. Various pile foundation construction devices, such as piling and drilling, must be mounted on the frame to perform these operations. Crawler pile frames are one type of pile frame, utilizing crawler tracks for movement, offering flexibility and convenience. Crawler pile frames typically consist of a chassis, a body, columns, diagonal supports, and a hydraulic system. Due to their lengthy columns (typically 20 to 40 meters), long-distance transport requires dismantling the columns and re-installing the masts at the new site.

[0003] At present, there are several crawler pile frames and their installation methods:

[0004] like Figure 1 As shown, the first method requires the assistance of a crane. When erecting the mast, the winch drives the pulley block to pull the column 01 up to 75 degrees. The crane assists in lifting the diagonal support cylinder to the installation position, and then the diagonal support cylinder pulls the column vertically.

[0005] like Figure 2 As shown, the second method, when the mast height is relatively low, can be achieved using a set of cylinders. Column 01, cylinder 02, and the fuselage are hinged together to form a large triangle, and the cylinders' contraction and retraction adjust the verticality of the columns. However, this method requires a limited height for the mast's pile frame, resulting in a low fulcrum and reduced stability.

[0006] like Figure 3 As shown, the third method does not require crane assistance and uses two groups of cylinders 02 to perform compound actions to erect the mast. During the operation, the synchronization requirements for the mast-erecting cylinders are particularly high, and the operation is difficult.

[0007] In summary, how to provide a pile frame that does not require crane assistance and has simple mast erection operation is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a pile frame, which can pull the column assembly to a vertical state without the assistance of a crane during use, and the mast erection process is convenient and easy to operate, and does not require the consistent movement of multiple cylinders, thereby reducing the difficulty of operation.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The core of the present invention is to provide a pile frame. During use, the column assembly can be pulled to a vertical state without the assistance of a crane. The mast erection process is convenient and easy to operate, and does not require the coordinated movement of multiple cylinders, thereby reducing the difficulty of operation.

[0042] Please refer to Figures 4 to 10 .

[0043] This specific embodiment discloses a pile frame, comprising: a rotary platform 4, a front bracket 3 hinged to the rotary platform 4, a column assembly 2 hinged to the front bracket 3, an oblique support 9 and a mast assembly 7;

[0044] The vertical mast assembly 7 includes a main body, a vertical mast winch 72 and a retractable power part. One end of the main body is hinged to the rotating platform 4, and the other end is hinged to the inclined support 9. The other end of the inclined support 9 is hinged to the column assembly 2; the power part is retractable, and one end of the power part is hinged to the rotating platform 4, and the other end is hinged to the main body to adjust the rotation angle of the main body relative to the rotating platform 4.

[0045] During the use of the pile frame provided in this specific embodiment, when the column assembly 2 needs to be erected, it is first necessary to drive the main body to rotate relative to the rotary platform 4 through the power unit, so that the end of the main body hinged to the oblique support 9 is lifted. After it is lifted to a suitable height, the power unit is controlled to retract, and the wire rope on the mast winch 72 forms a multiplier group through the upper pulley group 74 and the lower pulley group 75 to pull up the column assembly 2 to about 75 degrees, and then the oblique support 9 is controlled to retract, driving the column assembly 2 to rotate relative to the front bracket 3 until the column assembly 2 is in a vertical state.

[0046] Compared with the prior art, the pile frame provided in this specific embodiment does not require the assistance of a crane during use, and the column assembly 2 can be pulled to a vertical state. In addition, the mast erection process is convenient and easy to operate, and does not require the coordinated movement of multiple cylinders, thereby reducing the difficulty of operation.

[0047] In a specific embodiment, if Figure 10 As shown, the main body includes a straight frame 73 and a crossbeam 77 arranged perpendicular to the straight frame 73. One end of the straight frame 73 is hinged to the rotating platform 4, and the other end is hinged to the crossbeam 77. The diagonal support 9 is hinged to the crossbeam 77. There are two straight frames 73, and the two straight frames 73 are arranged in parallel. The power unit is a lifting cylinder 71; the diagonal support 9 is a telescopic cylinder. Of course, the power unit and the diagonal support 9 can also be electric screws, electric cylinders, etc. Compared with electric structures, setting the power unit as the lifting cylinder 71 and the diagonal support 9 as the telescopic cylinder can save costs, and the finished structures of the lifting cylinder 71 and the telescopic cylinder are easy to obtain.

[0048] During use, when the lifting cylinder 71 is extended, it can drive the straight frame 73 to rotate relative to the rotary platform 4, so that the end of the straight frame 73 connected to the oblique support 9 is lifted.

[0049] Preferably, the lifting cylinder 71 is hinged to a non-end position of the straight frame 73 .

[0050] The two straight frames 73 may correspond to different lifting cylinders 71 respectively, or may correspond to the same lifting cylinder 71 , which is determined according to actual conditions and will not be elaborated here.

[0051] In a specific embodiment, if Figure 10 As shown, the crossbeam 77 includes a fixed end 771, a telescopic end 772 connected to the fixed end 771 and telescopically extendable along the length direction of the crossbeam 77, and a telescopic power member 76 that drives the telescopic end 772 to extend and retract relative to the fixed end 771; the fixed end 771 is hingedly connected to the I-frame 73, and the end of the telescopic end 772 is provided with an ear seat for hinged connection to the oblique support 9; the oblique support 9 is hingedly connected to the ear seat.

[0052] like Figure 9As shown, there are two oblique supports 9 and two telescopic ends 772 , and the two telescopic ends 772 are telescopically arranged at both ends of the fixed end 771 , and the oblique supports 9 are connected to the telescopic ends 772 in a one-to-one correspondence.

[0053] During use, after the telescopic end 772 is extended, the length of the base of the triangle formed by the oblique support 9, the crossbeam 77, and the column assembly 2 can be increased, thereby improving the stability of the structure.

[0054] In a specific embodiment, if Figure 10 As shown, the main body includes an upper pulley block 74 provided on the crossbeam 77 and a lower pulley block 75 provided on the rotary platform 4, and the wire rope is wound around the mast winch 72, the upper pulley block 74, and the lower pulley block 75 in sequence; in the process of use, when the pile frame is in Figure 6 In the position shown, the column assembly 2 can be lifted by the mast winch 72 so that the column assembly 2 forms an angle of about 75° with the vertical direction.

[0055] In a specific embodiment, the rotating platform 4 is provided with a support rod for supporting the cross beam 77, and the support rod is detachably connected to the cross beam 77. During use, when the cross beam 77 needs to be moved during the process of erecting the column assembly 2, the connection between the cross beam 77 and the support rod can be released. When the column assembly 2 is erected to a vertical state, the support rod can be connected to the cross beam 77 to support and limit the cross beam 77, thereby improving the stability of the structure.

[0056] like Figure 6 As shown, the column assembly 2 includes a plurality of detachably connected column segments 21 .

[0057] like Figure 4 、 Figure 5 As shown, during transportation, some column segments 21 can be disassembled to reduce the space occupied by the column assembly 2; Figure 7 As shown, the rotary platform 4 is provided with a hoisting winch, and a pulley assembly 10 is provided at the end of the column segment 21 away from the rotary platform 4. One end of the wire rope with a hook portion is connected to the hoisting winch, and the other end passes through the pulley assembly 10. After part of the column segment 21 is disassembled, the column assembly 2 is driven to rotate relative to the front bracket 3 through the oblique support 9, and a pulley structure is provided on the remaining undisassembled column segment 21. At this time, the pile frame can be used as a small crane.

[0058] like Figure 4-10As shown, the pile frame includes: a column assembly 2, a front bracket 3, a rotary platform 4, a separation device 5, a crawler chassis 6, a mast assembly 7, a counterweight 8, an oblique support 9, a pulley assembly 10, etc. The goose head 1 is fixed to the top of the column assembly 2 by bolts. The column assembly 2 is hinged to the front bracket 3, and the front bracket 3 is hinged to the rotary platform 4. The separation device 5 connects the crawler chassis 6 and the rotary platform 4 together. One end of the mast assembly 7 is hinged to the rotary platform 4, and the other end serves as the lower hinge point of the oblique support 9. The upper end of the oblique support 9 is hinged to the column assembly 2 to form a stable support. The counterweight 8 is fixed to the rear of the rotary platform 4 by bolts. In the process of using the pile frame provided in this application document, the mast erection operation of the entire machine does not require the assistance of a crane. Before erecting the mast, it is first necessary to lift the end of the straight frame 73 hinged to the oblique support 9 by the lifting cylinder 71, that is, to lift the crossbeam 77 until it is as shown. Figure 6 As shown, it is convenient for the subsequent wire rope and oblique support 9 to apply force to the column assembly 2; then control the vertical mast winch 72 action, the wire rope passes through the upper pulley group 74 and the lower pulley group 75 to form a multiplier group to pull up the column assembly 2 to Figure 7 then through the expansion and contraction of the diagonal support cylinder 9 to straighten the column assembly 2 to a vertical state, such as Figure 8 To further improve stability, the telescopic end 772 can be extended by the telescopic power member 76 to Figure 9 The status shown completes the mast erection operation.
