Description

Pile Frame

The present disclosure relates to the field of construction equipment technology, and more particularly to pile frames.

Pile frames are essential large-scale machinery tools in construction. Various foundation work devices such as pile driving and drilling are mounted on the pile frames to perform construction work. The crawler pile frame is one of the various types of pile frames, which can move flexibly and conveniently by crawler driving. The crawler pile frame is generally composed of a crawler chassis, a machine body, a column, a slope support, a power hydraulic system, etc. Because the length of the column is relatively long (usually in the range of 20 to 40 meters), the column must be lowered and disassembled during long-distance transportation, and then installed and assembled again when arriving at a new site.

Currently, there are several types of crawler pile frames and their installation methods, as follows:

As shown in Fig. 1, the crawler pile frame of the first type requires the assistance of a crane. During the installation work, the column 01 is pulled up to 75 degrees by a pulley block driven by a winch, and then pulled vertically by a slant support cylinder raised to the installation position with the assistance of a crane.

As shown in Fig. 2, when the installation height is low, the second type of crawler pile frame uses a set of cylinders for installation work. The column 01, the cylinder 02 and the machine body are hingedly connected to form a large triangle. The verticality of the column is adjusted by the extension and contraction of the cylinder. The column of the pile frame installed in this way should not be too high, and the support point is low and the stability is low.

As shown in Fig. 3, the third type of crawler pile frame does not require the assistance of a crane, and two sets of cylinders 02 cooperate to perform the installation work. The synchronization requirement of the installation cylinders during the work is particularly high, which makes the work difficult.

In view of the above, those skilled in the art are seeking a solution for providing a pile frame that does not require crane assistance and is easy to install.

In view of the above, an object of the present disclosure is to provide a pile frame capable of vertically pulling a column assembly without the assistance of a crane during use, which is convenient for installation and easy to operate. The difficulty of the work is reduced because multiple cylinders do not need to operate simultaneously.

The core of the present disclosure is to provide a pile frame that can vertically pull a column assembly without the assistance of a crane during use, and has a convenient installation process and simple installation work. In the present disclosure, the difficulty of the work is reduced because there is no need for multiple cylinders to operate simultaneously.

Referring to Figures 4 to 10,

The pile frame provided in the present embodiment comprises a rotating platform 4, a front bracket 3 hingedly connected to the rotating platform 4, a column assembly 2 hingedly connected to the front bracket 3, a slope support 9, and an installation assembly 7.

The above installation assembly 7 includes a main body, an installation winch 72, and an expandable power unit. One end of the main body is hingedly connected to the rotation platform 4, and the other end is hingedly connected to the inclined support 9. The other end of the inclined support 9 is hingedly connected to the pillar assembly 2. The power unit is arranged in an expandable manner, and one end of the power unit is hingedly connected to the rotation platform 4, and the other end is hingedly connected to the main body to adjust a rotation angle of the main body with respect to the rotation platform 4.

In the process of using the pile frame provided in the present embodiment, when installing the pillar assembly 2, first, the main body is driven to rotate with respect to the rotating platform 4 by the power unit, so that an end of the main body portion hingedly connected to the inclined support 9 is lifted. When the end of the main body portion hingedly connected to the inclined support 9 is lifted to an appropriate height, the power unit is controlled to retract. The steel wire rope of the installation winch 72 pulls the pillar assembly 2 up to about 75 degrees through the group of double pulleys formed by the upper pulley block 74 and the lower pulley block 75. Then, the inclined support 9 is controlled to retract, so that the pillar assembly 2 is driven to rotate with respect to the front bracket 3, so that the pillar assembly 2 rotates until it becomes vertical.

Compared with the existing technology, the pile frame provided in the present embodiment can pull the column assembly 2 into a vertical state without the assistance of a crane during the use process. The installation process is convenient, the installation work is simple, and the operation consistency of a plurality of oil cylinders is not required, so the difficulty of the work is reduced.

In one embodiment, as illustrated in FIG. 10, the main body includes a straight bracket 73 and a cross beam 77 arranged perpendicular to the straight bracket 73. One end of the straight bracket 73 is hingedly connected to the rotating platform 4, and the other end is hingedly connected to the cross beam 77. The inclined support 9 is hingedly connected to the cross beam 77. Two straight brackets 73 may be arranged in parallel. The power unit may be a lifting cylinder 71, and the inclined support 9 may be an expandable cylinder. Alternatively, the power unit and the inclined support 9 may be an electric screw, a robo-cylinder, or other structures. Compared with the electric structure, implementing the power unit as a lifting cylinder 71 and the inclined support 9 as an expandable cylinder can reduce costs, and the completed structures of the lifting cylinder 71 and the expandable cylinder can be easily obtained.

In use, when the lifting cylinder 71 is extended, it drives the straight bracket 73 to rotate relative to the rotating platform 4, thereby lifting the end of the straight bracket 73 connected to the inclined support 9.

Preferably, the lifting cylinder 71 is hingedly connected to a portion other than both ends of the straight bracket 73.

The two straight brackets 73 may be configured to correspond to different lifting cylinders 71, or they may share a single lifting cylinder 71, which may be determined according to actual circumstances and will not be described further here.

In one embodiment, as illustrated in FIG. 10, the cross beam 77 includes a fixed member 771, an extension member 772 connected to the fixed member 771 and extendable in the longitudinal direction of the cross beam 77, and an extendable actuator 76 configured to extend or retract the extension member 772 relative to the fixed member 771. The fixed member 771 is hingedly connected to the straight bracket 73, and a lug is provided at an end of the extension member 772 for hinged connection with the inclined support 9. The inclined support 9 is hingedly connected to the lug.

As illustrated in FIG. 9, two inclined supports 9 and two extensions 772 may be provided. The two extensions 772 are each extendibly arranged at both ends of the fixed part 771, and the two inclined supports 9 are each connected to the two extensions 772 in a one-to-one correspondence.

When in use, the extension portion 772 can be extended to increase the length of the base of the triangle formed by the inclined support 9, the cross beam 77, and the column assembly 2, thereby improving structural stability.

In one embodiment, as illustrated in FIG. 10, the main body includes an upper pulley block 74 positioned on the cross beam 77 and a lower pulley block 75 positioned on the rotating platform 4. A steel wire rope is sequentially wound around the installation winch 72, the upper pulley block 74 and the lower pulley block 75. In use, when the pile frame is in the position illustrated in FIG. 6, the column assembly 2 can be lifted by the installation winch 72 to form an angle of about 75 degrees between the column assembly 2 and the vertical direction.

In one embodiment, the rotating platform 4 is provided with a support bar for supporting the cross beam 77. The support bar can be detachably connected to the cross beam 77. In use, when the cross beam 77 needs to be moved during the process of installing the pillar assembly 2, the connection between the cross beam 77 and the support bar can be released. When the pillar assembly 2 is installed vertically, the support bar can be connected to the cross beam 77 to support and restrict the cross beam 77, thereby improving structural stability.

As illustrated in FIG. 6, the pillar assembly 2 includes a plurality of pillar sub-assemblies 21 that are detachably connected to one another.

As illustrated in FIGS. 4 and 5, a portion of the column sub-assembly 21 may be disassembled during transportation to reduce the space occupied by the column assembly 2. As illustrated in FIG. 7, a hoist winch is provided on the rotating platform 4, and a pulley assembly 10 is provided at an end of the column sub-assembly 21 located away from the rotating platform 4. One end of a steel wire rope equipped with a hook is connected to the hoist winch, and the other end of the steel wire rope is arranged to pass through the pulley block 10. After a portion of the column sub-assembly 21 is disassembled, the column assembly 2 is driven to rotate relative to the front bracket 3 by the inclined support 9. In addition, a pulley structure may be provided on the non-disassembled column sub-assembly 21. In this way, the pile frame can be used as a small crane.

As shown in FIGS. 4 to 10, the pile frame includes a column assembly 2, a front bracket 3, a rotating platform 4, a separation unit 5, a crawler chassis 6, an installation assembly 7, a counterweight 8, an inclined support 9, a pulley assembly 10, etc. A gooseneck boom 1 is fixed to an upper end of the column assembly 2 with a bolt. The column assembly 2 is hingedly connected to the front bracket 3, and the front bracket 3 is hingedly connected to the rotating platform 4. The separation unit 5 connects the crawler chassis 6 to the rotating platform 4. One end of the installation assembly 7 is hingedly connected to the rotating platform 4, and the other end serves as a lower hinge point of the inclined support 9. The upper end of the inclined support 9 is hingedly connected to the column assembly 2 to form a stable support. The counterweight 8 is fixed to the rear end of the rotating platform 4 with a bolt. In the process of using the pile frame provided in the present disclosure, the installation work of the entire machine is performed without the assistance of a crane. Before performing the installation work, first, the end of the straight bracket 73 hingedly connected to the inclined support 9 is lifted by the lifting cylinder 71. That is, the cross beam 77 is lifted to the position shown in FIG. 6, thereby facilitating the steel wire rope and the inclined support 9 to apply force to the column assembly 2 thereafter. Next, the installation winch 72 is controlled to operate so that the steel wire rope pulls up the column assembly 2 through the group of sheaves formed by the upper pulley block 74 and the lower pulley block 75 to the position shown in FIG. 7. Then, the column assembly 2 is pulled to a vertical state as shown in FIG. 8 by the extension or contraction operation of the inclined support cylinder of the inclined support 9. To further improve stability, the extension part 772 can be extended by the extension actuator 76 to the state shown in Fig. 9, thereby completing the installation work.

Various implementations of this specification are described in a progressive manner, with each implementation explaining the differences from other implementations. The same or similar parts between the implementations may be referenced to each other. All combinations of implementations provided in this disclosure are within the scope of this disclosure and will not be described repeatedly herein.
