[0061] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0062] The core of the present application is to provide a pile driver, which has a lower requirement for the flatness of a construction site when performing pile pressing work.

[0063] This application provides a pile driver, which includes a base 1, a pile driving assembly 2, a support column assembly 3, and a first drive assembly 4; wherein, the pile driving assembly 2 is used for driving piles and is installed on the support column assembly 3; the support column assembly 3 is rotatably disposed on the base 1 with the transverse axis as the axis, the first drive assembly 4 is installed on the base 1, and the output end of the first drive assembly 4 is connected to the support column assembly 3 for driving the support column assembly 3 to rotate, so as to adjust the included angle between the support column assembly 3 and the longitudinal direction.

[0064] Specifically, such as Figures 1 to 3 As shown, the base 1 is used to install and / or support the pile driving assembly 2, the support column assembly 3, and the first drive assembly 4, etc. The pile driving assembly 2 is used to press the pile body 13 into the ground, so the pile driver has the function of lifting and pushing the pile body 13 along the Y direction. The bottom end of the support column assembly 3 is rotatably connected to the top of the base 1 with the X direction as the axis. Correspondingly, the output end of the first drive assembly 4 is connected to the support column assembly 3 so as to drive the support column assembly 3 to rotate around the X direction. Since the pile driving assembly 2 is installed on the support column assembly 3, the pile driving assembly 2 can rotate with the support column assembly 3 with the X direction as the axis relative to the base 1.

[0065] For example, when the ground has a 15-degree angle with the horizontal plane, after moving the pile driver into position, start the first drive component 4 to drive the support column component 3 to rotate to a position with a preset angle with the Y direction. For example, drive the support column component 3 to rotate to a position with a 78-degree angle between itself and the Y direction. In summary, when using this pile driver for pile driving operations, the flatness requirements of the construction site are relatively low.

[0066] It should be noted that the type of support column assembly 3 is not limited, as long as it meets the requirements for installation and support. For example, in some specific embodiments, the support column assembly 3 adopts a rod with a uniform cross-sectional shape, such as a square rod or a round rod; or, preferably, in some specific embodiments, the support column assembly 3 includes several straight support columns, and each support column has a connecting seat, such as a flange, at least one end of which is fixedly connected by the connecting seat to form a straight column as the support column assembly 3, etc.

[0067] To further reduce the flatness requirements of the construction site during pile driving operations, based on the above embodiment, the base 1 includes a base body 101 and four retractable support legs 102; the pile driving assembly 2, the support column assembly 3, and the first drive assembly 4 are all connected to the base body 101; the four support legs 102 are arranged in a rectangular shape, and the fixed ends of the support legs 102 are connected to the base body 101, while the movable ends are used to support the construction site, support the base body 101, and adjust the position of the corresponding top corner of the base body 101.

[0068] like Figure 3 ,Figure 5 、 Figure 7 and Figure 8 As shown in the drawings, the support column assembly 3, the first driving assembly 4 and the like are mounted on the base body 101, and the support legs 102 extending along the Y direction are mounted on the base body 101, and the four support legs 102 are arranged in a rectangular layout to stably support the base body 101 and the components thereon.

[0069] In use, for example, when the local terrain is stepped from left to right, the left support leg 102 is supported on the left step, and the right support leg 102 is supported on the right step, so that the base body 101 is as horizontal as possible, which is beneficial to further reduce the flatness requirement of the construction site when the pile machine is performing pile pressing operation.

[0070] Of course, the number of support legs 102 is not limited to four, as long as the functional requirements described above can be met, for example, in some embodiments, the number of support legs 102 is eight, of which four support legs 102 are arranged at the corresponding top corner positions of the rectangular layout area, and the remaining four support legs 102 are arranged at the midpoint positions of the corresponding sides of the rectangular layout area; or in some embodiments, the number of support legs 102 is twelve, of which four support legs 102 are arranged at the corresponding top corner positions of the rectangular layout area, and the remaining eight support legs 102 are arranged at the corresponding sides of the rectangular layout area and uniformly arranged on the corresponding sides.

[0071] In order to improve the pile pressing function of the pile machine and improve the construction efficiency, on the basis of the above embodiments, the pile pressing assembly 2 comprises an impact hammer; further comprising a first hoisting assembly 5 and a second hoisting assembly 6; the hoisting rope of the first hoisting assembly 5 is used for detachable connection with the accessory to lift the accessory; the hoisting rope of the second hoisting assembly 6 is connected with the impact hammer to lift the longitudinally arranged impact hammer.

[0072] Specifically, two groups of hoisting assemblies are arranged on the base body 101, i.e. the first hoisting assembly 5 and the second hoisting assembly 6, which can adopt winch mechanism or electric hoist to lift the corresponding components.

[0073] Correspondingly, the pile pressing assembly 2 is provided with an impact hammer, and the hoisting rope of the second hoisting assembly 6 is connected to the impact hammer, so that the impact hammer can be driven to move back and forth along the Y direction, and when the pile machine is used for operation, it is not necessary to drill holes, but the pile body 13 can be pressed into the ground by the impact of the impact hammer; and the first hoisting assembly 5 is provided, which can be connected to the pile body 13, drill rod or other accessories by the hoisting rope of the first hoisting assembly 5 for construction.

[0074] It should be noted that the pile pressing assembly 2 is not limited to the type including the impact hammer as described above, for example, the pile pressing assembly 2 includes a vibration pile driver.

[0075] In order to improve the stability of the equipment and reduce the disassembly difficulty of the pile driver, on the basis of the above embodiment, the support column assembly 3 is provided with a machine head assembly 7, the machine head assembly 7 includes a support seat 701, a plurality of first pulleys 702 and a plurality of second pulleys 703, the first pulleys 702 and the second pulleys 703 are rotatably arranged on the support seat 701; the first hoisting assembly 5 is a hoisting device, and the hoisting rope of the first hoisting assembly 5 is movably wound on the first pulley 702; the second hoisting assembly 6 is a hoisting device, and the hoisting rope of the second hoisting assembly 6 is movably wound on the second pulley 703; and the support column assembly 3 is arranged on one side of the base body 101 along the vertical direction, the first hoisting assembly 5 and the second hoisting assembly 6 are arranged on the other side of the base body 101 along the vertical direction, and any two of the vertical direction, the horizontal direction and the longitudinal direction are perpendicular to each other.

[0076] Specifically, as shown in Figure 3 the first hoisting assembly 5 and the second hoisting assembly 6 are both hoisting mechanisms, and the first hoisting assembly 5 and the second hoisting assembly 6 are both installed on the base body 101.

[0077] Correspondingly, the support seat 701 is arranged on the support column assembly 3, and the rotatable first pulley 702 and the second pulley 703 are installed on the support seat 701, both the first pulley 702 and the second pulley 703 are fixed pulleys, the free end of the hoisting rope in the first hoisting assembly 5 is wound outside the first pulley 702 to connect the accessory, and the free end of the hoisting rope in the second hoisting assembly 6 is wound outside the second pulley 703 to connect the impact hammer.

[0078] In summary, the accessory is hoisted by the cooperation of the first pulley 702 and the first hoisting device, and the impact hammer is hoisted by the cooperation of the second pulley 703 and the second hoisting device, since one end of the hoisting rope is connected to the corresponding component, the middle position is supported on the support column assembly 3, and the other end is connected to the hoisting assembly arranged on the base body 101, and the support column assembly 3 is installed on the left side of the base body 101 along the Z direction, and the first hoisting assembly 5 and the second hoisting assembly 6 are installed on the right side of the base body 101 along the Z direction, so that the stress of the pile driver is more uniform, and the stability is higher; and since the first pulley 702 and the second pulley 703 are both installed on the support seat 701, only the support seat 701 needs to be operated during disassembly.

[0079] To improve the stability of the support column assembly 3, on the basis of the above embodiment, a reinforcing connection assembly 8 is further included; the bottom end of the support column assembly 3 is rotatably connected to the base body 101; the output end of the first driving assembly 4 is connected to the middle column segment of the support column assembly 3; the reinforcing connection assembly 8 is installed on the base body 101, and the reinforcing connection assembly 8 is detachably connected to the top of the support column assembly 3.

[0080] For example, as shown in Figure 2 and Figure 3 The bottom end of the support column assembly 3 is connected to the hinge seat above the base body 101 through a pin shaft, and in cooperation, the reinforcing connection assembly 8 is connected to the top of the base body 101. Specifically, the lower right end of the reinforcing connection assembly 8 is fixedly connected to the base body 101, and the upper left end is used to be connected to the top of the support column assembly 3 after the support column assembly 3 is adjusted in place by the first driving assembly 4. Then the support column assembly 3, the base body 101 and the reinforcing connection assembly 8 form a triangular stable structure, which reduces the risk of the support column assembly 3 losing constraint and tilting to the left side, and because the top end of the reinforcing connection assembly 8 is detachably connected to the support column assembly 3, the reinforcing connection assembly 8 can loosen the support column assembly 3 to facilitate the adjustment of the position of the support column assembly 3 by the first driving assembly 4.

[0081] Furthermore, the output end of the first driving assembly 4 is connected to the middle height column segment of the support column assembly 3, in other words, the position where the support column assembly 3 is connected to the first driving assembly 4 is located between the position where the support column assembly 3 is connected to the base body 101 and the position where the support column assembly 3 is connected to the reinforcing connection assembly 8, then the support column assembly 3, the base body 101 and the first driving assembly 4 form another triangular stable structure to ensure the stability of the support column assembly 3 during adjustment.

[0082] It should be noted that the type of reinforcing connection assembly 8 is not limited, as long as it can achieve the above functions, for example, the reinforcing connection assembly 8 can include a steel wire rope, one end of which is buckled on the top of the base body 101, and the other end is buckled on the top of the support column assembly 3.

[0083] To further improve the stability of the pile driver, on the basis of the above embodiment, the reinforcing connecting assembly 8 comprises two reinforcing connecting rods 801, the first ends of the reinforcing connecting rods 801 are rotatably connected to the base body 101, the second ends are detachably connected to the support column assembly 3, and one reinforcing connecting rod 801 is located on one side of the support column assembly 3 along the transverse direction, and the other reinforcing connecting rod 801 is located on the other side of the support column assembly 3 along the transverse direction; the first driving assembly 4 comprises two first telescopic rods 401, the first ends of the first telescopic rods 401 are movably connected to the base body 101, and the second ends are movably connected to the support column assembly 3, and one first telescopic rod 401 is located on one side of the support column assembly 3 along the transverse direction, and the other first telescopic rod 401 is located on the other side of the support column assembly 3 along the transverse direction.

[0084] For example, as shown in Figure 3 , the reinforcing connecting rod 801 can adopt a straight rod body or an F-shaped rod body, and the upper left end of the reinforcing connecting rod 801 is used for connection on the support column assembly 3, and since the lower right end of the reinforcing connecting rod 801 is rotatably connected to the base body 101, the upper end of the reinforcing connecting rod 801 can be connected to the support column assembly 3 in different positions, and the two reinforcing connecting rods 801 are distributed on the two sides of the support column assembly 3 along the X direction.

[0085] Similarly, as shown in Figure 3 , the first telescopic rod 401 adopts a straight telescopic rod, and the upper left end of the first telescopic rod 401 is used for connection on the support column assembly 3, and since the lower right end of the first telescopic rod 401 is rotatably connected to the base body 101, when the support column assembly 3 is pulled to adjust its position, the first telescopic rod 401 can adjust its own position to stably pull the support column assembly 3, and the two first telescopic rods 401 are distributed on the two sides of the support column assembly 3 along the X direction.

[0086] In summary, such a setting can further reduce the risk of the support column assembly 3 losing constraint and tilting to the left side, and avoid the support column assembly 3 from tilting along the X direction, which is conducive to ensuring the position accuracy of the pile body 13 pressed by the pile driver.

[0087] In order to adjust the position of the pile driver and improve the stability of the pile driver during the pile pressing operation, the base 1 further comprises a central support assembly 103, a first support assembly 104 and a second support assembly 105 on the basis of the above embodiment; the central support assembly 103 is located between the first support assembly 104 and the second support assembly 105; the base body 101 is movably arranged on the top of the central support assembly 103 along the vertical direction; the support leg 102 comprises a support leg body 1021 and a track wheel 1022; the support leg body 1021 is a telescopic rod body and extends along the longitudinal direction; the first end of the support leg body 1021 is connected to the base body 101, and the second end is connected to the track wheel 1022 by a ball joint; the track wheels 1022 of the two support legs 102 are movably arranged on the corresponding first support assembly 104 along the transverse direction; the track wheels 1022 of the remaining two support legs 102 are movably arranged on the corresponding second support assembly 105 along the transverse direction; the second driving assembly 9 and the third driving member 10 are further included; the first output end of the second driving assembly 9 is connected to the track wheel 1022 matched with the first support assembly 104; the second output end of the second driving assembly 9 is connected to the track wheel 1022 matched with the second support assembly 105, for driving the track wheel 1022 to move along the transverse direction; the output end of the third driving member 10 is connected to the base body 101, for driving the base body 101 to move along the vertical direction.

[0088] As shown in Figure 3 and Figure 5 , the support leg 102 is composed of the support leg body 1021 and the track wheel 1022; the support leg body 1021 extends along the Y direction; the upper end of the support leg body 1021 is connected to the top of the base body 101, and the lower end is connected to the top of the track wheel 1022; correspondingly, the pile driver is provided with the first support assembly 104 and the second support assembly 105 which are independent of each other; the first support assembly 104 and the second support assembly 105 are arranged side by side along the Z direction; the first support assembly 104 and the second support assembly 105 both have tracks extending along the X direction; the track wheels 1022 at the bottom of the left two support legs 102 are in sliding fit with the track of the left first support assembly 104; the track wheels 1022 at the bottom of the right two support legs 102 are in sliding fit with the track of the right second support assembly 105.

[0089] The first support assembly 104 and the second support assembly 105 both comprise the base 1 and the track; the track is mounted on the base 1; the base 1 has a limiting portion, such as an L-shaped bent plate or a frame structure with a notch, for abutting against the track wheel 1022, so as to prevent the track wheel 1022 from being separated from the corresponding support assembly from the top opening of the limiting slot, and to enable the support leg body 1021 to drive the corresponding support assembly to rise when the support leg body 1021 is shortened and the track wheel 1022 is lifted.

[0090] Preferably, as shown in Figure 3 , Figure 5 ,Figure 7 and Figure 8 As shown in the drawings, the base 1 is a linear seat body with a limiting groove opened at the top, the base 1 extends along the X direction, the limiting groove extends along the length direction of the base 1, the track is embedded in the limiting groove, and the top of the base 1 has two opposite extending limiting plates which shield the top part of the opening of the limiting groove and abut against the track wheel 1022 to prevent the track wheel 1022 from being separated from the corresponding support assembly from the top opening of the limiting groove. In this way, the weight of the support assembly is low.

[0091] Furthermore, the central support assembly 103 is arranged between the first support assembly 104 and the second support assembly 105 arranged side by side, and the top of the central support assembly 103 is provided with a guide structure such as a guide rail or a sliding groove extending along the Z direction for guiding the base body 101 to move along the Z direction.

[0092] The pile machine is also provided with a second driving assembly 9 which can output linear movement. For example, the third driving member 10 can include two sets of gear and rack structures or can include two sets of screw and block structures, etc. to connect the corresponding track wheels 1022 through the corresponding gear and rack structures or screw and block structures. The left first output end of the second driving assembly 9 is connected to the track wheel 1022 supported on the left first support assembly 104, and the right second output end is connected to the track wheel 1022 supported on the right second support assembly 105, so as to drive the track wheels 1022 to move along the X direction.

[0093] The pile machine is also provided with a third driving member 10 which can output linear movement. For example, the third driving member 10 can adopt a gear and rack structure. The output end of the third driving member 10 is connected to the base body 101 or the component connected to the base body 101, so as to drive the base body 101 to move along the Z direction.
