Description

[Technical Field]

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

[0002] Pile frames are large machine tools that are essential in construction work, and all types of pile foundation construction equipment, such as pile driving and drilling, must be mounted on pile frames to carry out construction work. Crawler pile frames are one type of pile frame, and are moved to their location using a crawler travel method, featuring flexibility and convenience. Crawler pile frames usually consist mainly of a chassis, body, column, tilt support, and power hydraulic system, etc., and because the column is long (usually 20 to 40 meters), when transporting over long distances, the mast must be tilted sideways relative to the column to remove it, and then re-erected and re-attached 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, Type 1 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. The column 01, cylinder 02 and the frame are hinged to a large triangle, and the cylinder contracts to adjust the verticality of the column. The pile frame used to raise the mast in this way must not have too high a column, as the support point is low and the stability is not high.

[0006] As shown in Figure 3, the third type does not require the assistance of a crane and uses 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 that does not require the assistance of a crane truck and allows for easy mast erection operation is a problem that must be solved urgently by those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0023] The essence of the present invention is to provide a pile frame that can lift a column assembly to a vertical position without the assistance of a crane during use, and that makes the mast raising process convenient and easy to operate, eliminating the need for multiple cylinders to operate in unison, thereby reducing the difficulty of operation.

[0024] Please refer to Figures 4 to 10.

[0025] This particular embodiment discloses a pile frame, including a rotating platform 4, a front bracket 3 hinged to the rotating platform 4, a column assembly 2 hinged to the front bracket 3, a tilting support 9, and a mast raising assembly 7; The mast raising assembly 7 includes a main body, a mast raising winch 72, and a telescopically installed power unit, one end of the main body is hingedly connected to the rotating platform 4 and the other end is hingedly connected to the tilting support 9, the other end of which is hingedly connected to the column assembly 2, the power unit is telescopically installed, and one end of the power unit is hingedly connected to the rotating platform 4 and the other end is hingedly connected to the main body, thereby adjusting the rotation angle of the main body relative to the rotating platform 4.

[0026] In the process of using the pile frame provided in this specific embodiment, when the column assembly 2 needs to be erected, the power unit first drives the main body to rotate relative to the rotating platform 4, and then controls the power unit to lift one end of the main body that is hinged to the inclined support 9, and after lifting it to an appropriate height, retract it. The wire rope of the mast erecting hoist 72 forms a magnification group via the upper pulley block 74 and the lower pulley block 75, and lifts the column assembly 2 to reach 75 degrees left and right. Then, controls the inclined support 9 to retract, and rotates the column assembly 2 relative to the front bracket 3 until the column assembly 2 is in a vertical state.

[0028] 10 , the main body includes a bar frame 73 and a cross rail 77 perpendicular to the bar frame 73. One end of the bar frame 73 is hinged to the rotating platform 4 and the other end is hinged to the cross rail 77, and the tilt support 9 is hinged to the cross rail 77. There are two bar frames 73, and the two bar frames 73 are installed in parallel. The power unit is a lift cylinder 71, and the tilt support 9 is a telescopic cylinder. Of course, the power unit and the tilt support 9 can also be electric screws, electric cylinders, etc. However, compared to an electric structure, installing the power unit as a lift cylinder 71 and the tilt support 9 as a telescopic cylinder can save costs and easily obtain the complete lift cylinder 71 and telescopic cylinder structure.

[0029] In the process of use, after the lift cylinder 71 is extended, the bar-shaped frame 73 can be rotated relative to the rotating platform 4, and one end of the bar-shaped frame 73 connected to the inclined support 9 is lifted.

[0030] Preferably, the lift cylinder 71 is hinged to a non-end position of the one-piece frame 73 .

[0031] The two straight frames 73 may correspond to different lift cylinders 71 or the same lift cylinder 71, and the specifics are determined according to the actual situation, and will not be detailed here.

[0032] In one specific embodiment, as shown in FIG. 10 , the cross rail 77 includes a fixed end 771, a telescopic end 772 telescopically connected to the fixed end 771 along the longitudinal direction of the cross rail 77, and a telescopic power member 76 that telescopically extends and retracts the telescopic end 772 relative to the fixed end 771.

[0033] As shown in FIG. 9, there are two inclined supports 9 and two telescopic ends 772, and the two telescopic ends 772 are respectively installed at both ends of the fixed end 771 so as to be telescopic, and the inclined supports 9 are connected to the telescopic ends 772 respectively.

[0034] In use, after the telescopic end 772 is extended, the length of the base of the triangle formed by the inclined support 9, the cross rail 77 and the column assembly 2 can be increased, thereby improving the stability of the structure.

[0035] In one specific embodiment, as shown in FIG. 10, the main body includes an upper pulley block 74 installed on the cross rail 77 and a lower pulley block 75 installed on the rotating platform 4, and the wire rope is wound around the mast raising hoist 72, the upper pulley block 74, and the lower pulley block 75 in sequence. During use, when the pile frame is in the position shown in FIG. 6, the column assembly 2 can be pulled up by the mast raising hoist 72 so that the column assembly 2 forms an included angle of 75° on the left and right with respect to the vertical direction.

[0036] In one specific embodiment, the rotating platform 4 is equipped with support rods for supporting the cross rail 77, and the support rods are detachably connected to the cross rail 77. During use, if the cross rail 77 needs to be moved while erecting the column assemblies 2, the connection between the cross rail 77 and the support rods can be released. After the column assemblies 2 are erected in an upright position, the support rods can be reconnected to the cross rail 77, providing support and limiting the position of the cross rail 77 and improving the stability of the structure.

[0037] As shown in FIG. 6, the column assembly 2 includes a number of removably connected column segments 21.

As shown in Figure 7, a lifting hoist is installed on the rotating platform 4, and a pulley assembly 10 is installed at the end of the column segment 21 away from the rotating platform 4. One end of a wire rope with a hook attached is connected to the lifting hoist and the other end is installed through the pulley assembly 10. After some column segments 21 are removed, the column assembly 2 is rotated relative to the front bracket 3 via the inclined support 9, and a pulley structure is installed on the remaining column segments 21 that will not be removed. In this case, the pile frame may be used as a terhar.

[0039] As shown in Figures 4 to 10, the pile frame includes a column assembly 2, a front bracket 3, a rotating platform 4, a separation device 5, a crawler chassis 6, a mast raising assembly 7, a counterweight 8, an inclined support 9, a pulley assembly 10, etc. The luffing mechanism 1 is fixed to the top of the column assembly 2 via a bolt, the column assembly 2 is hingedly connected to the front bracket 3, the front bracket 3 is hingedly connected to the rotating platform 4, the separation device 5 connects the crawler chassis 6 and the rotating platform 4, the mast raising assembly 7 has one end hingedly connected to the rotating platform 4 and one end as a lower hinge connection point of the inclined support 9, and the upper end of the inclined support 9 is hingedly connected to the column assembly 2, thereby forming a stable support. The counterweight 8 is fixed to the rear of the rotating platform 4 via bolts. When using the pile frame provided by this application, the mast raising operation of the entire machine does not require the assistance of a crane truck. Before raising the mast, first, the end of the inclined frame 73 that is hinged to the inclined support 9 is raised via the lift cylinder 71, that is, the cross rail 77 is raised to the state shown in FIG. 6, so that the wire rope and the inclined support 9 can conveniently urge the column assembly 2. Then, by controlling the operation of the mast raising hoist 72, the wire rope forms a magnification group via the upper pulley block 74 and the lower pulley block 75, and the column assembly 2 is raised to the position shown in FIG. 7. Then, as shown in FIG. 8, the inclined support cylinder of the inclined support 9 is extended to raise the column assembly 2 to a vertical position. To further improve stability, the telescopic end 772 is extended via the telescopic power member 76, and the mast raising operation can be completed to the state shown in FIG. 9.
