[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] The core of the present application is to provide a pile driver, which has low requirements on the flatness of the construction site when used for pile driving operations.

[0063] The present 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 the pile driving assembly 2 is installed on the support column assembly 3; the support column assembly 3 is rotatably arranged on the base 1 with a transverse 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, and is used to drive the support column assembly 3 to rotate so as to adjust the angle between the support column assembly 3 and the longitudinal direction.

[0064] Specifically, 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., wherein the pile driving assembly 2 is used to press the pile body 13 into the ground, and the pile driver has the function of lifting and lowering 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, and the output end of the first drive assembly 4 is connected to the support column assembly 3 to be able 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 compared to the base 1.

[0065] During use, for example, when the ground has an angle of 15 degrees with the horizontal plane, after the pile driver is moved into position, the first drive assembly 4 is started to drive the support column assembly 3 to rotate to a position with a preset angle with the Y direction, for example, the support column assembly 3 is driven to rotate to a position with an angle of 78 degrees between itself and the Y direction; in summary, when the pile driver is used for pile driving operations, the flatness requirements for 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 of installation and support. For example, in some specific embodiments, the support column assembly 3 adopts a rod body with a uniform cross-sectional shape, such as a square rod or a round rod, etc.; or, preferably, in some specific embodiments, the support column assembly 3 includes a plurality of sections of straight support columns, and at least one end of the support column has a connecting seat, such as a flange, and adjacent support columns are fixedly connected by the connecting seat to form a straight column as the support column assembly 3, etc.

[0067] In order to further reduce the flatness requirements for the construction site during pile driving operations, on the basis of the above embodiments, 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, and the movable ends are used to support on the construction site, for supporting the base body 101, and adjusting the position of the corresponding vertex angle of the base body 101.

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

[0069] When in use, for example, when the 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 requirements of the construction site when the pile driver performs pile driving operations.

[0070] Of course, the number of supporting legs 102 is not limited to four, as long as it can meet the above-mentioned functional requirements. For example, in some specific embodiments, the number of supporting legs 102 is eight, wherein four supporting legs 102 are respectively arranged at the corresponding top corners of the rectangular layout area, and the remaining four supporting legs 102 are respectively arranged at the midpoints of the corresponding sides of the rectangular layout area; or, in some specific embodiments, the number of supporting legs 102 is twelve, wherein four supporting legs 102 are respectively arranged at the corresponding top corners of the rectangular layout area, and the remaining eight supporting legs 102 are respectively arranged at the corresponding sides of the rectangular layout area, and are evenly arranged on the corresponding sides, etc.

[0071] In order to improve the pile driving function of the pile driver and improve the construction efficiency, on the basis of the above embodiment, the pile driving assembly 2 includes an impact hammer; it also includes a first lifting assembly 5 and a second lifting assembly 6; the lifting rope of the first lifting assembly 5 is used to be detachably connected to the accessories to lift the accessories; the lifting rope of the second lifting assembly 6 is connected to the impact hammer and is used to lift the impact hammer arranged along the longitudinal direction.

[0072] Specifically, two sets of lifting components are arranged on the base body 101, namely, a first lifting component 5 and a second lifting component 6. The first lifting component 5 and the second lifting component 6 can adopt a hoisting mechanism or an electric hoist, etc., so as to be able to lift corresponding components.

[0073] Correspondingly, the pile driving assembly 2 is equipped with an impact hammer. The lifting rope of the second lifting assembly 6 is connected to the impact hammer, which can drive the impact hammer to move back and forth along the Y direction. When using the pile driver for operation, there is no need to drill holes. The pile body 13 can be pressed into the ground by the impact action of the impact hammer; and it is equipped with a first lifting assembly 5. When in use, the lifting rope of the first lifting assembly 5 can be connected to the pile body 13, drill rod or any other type of accessories to facilitate construction.

[0074] It should be noted that the pile driving assembly 2 is not limited to the above-mentioned type including the impact hammer. For example, the pile driving assembly 2 includes a vibration pile driving hammer.

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

[0076] Specifically, Figure 3 As shown, the first hoisting assembly 5 and the second hoisting assembly 6 both adopt a hoisting mechanism, and the first hoisting assembly 5 and the second hoisting assembly 6 are both installed on the base body 101 .

[0077] Correspondingly, a support base 701 is arranged on the support column assembly 3, and a rotatable first pulley 702 and a second pulley 703 are installed on the support base 701, and the first pulley 702 and the second pulley 703 are both fixed pulleys. The free end of the lifting rope in the first lifting assembly 5 is wrapped around the outside of the first pulley 702 to connect to the accessories, and the free end of the lifting rope in the second lifting assembly 6 is wrapped around the outside of the second pulley 703 to connect to the impact hammer.

[0078] In summary, through the first pulley 702 and the first lifting equipment's coordinated lifting accessories, through the second pulley 703 and the second lifting equipment's coordinated lifting hammer, since one end of the lifting 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 lifting 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 lifting assembly 5 and the second lifting assembly 6 are installed on the right side of the base body 101 along the Z direction, the pile driver is more evenly stressed and has higher stability in use; and since the first pulley 702 and the second pulley 703 are both installed on the support seat 701, during the disassembly and assembly process, only the support seat 701 needs to be operated.

[0079] In order to improve the stability of the support column assembly 3, on the basis of the above embodiment, it also includes a reinforced connection assembly 8; the bottom end of the support column assembly 3 is rotatably connected to the base body 101; the output end of the first drive assembly 4 is connected to the middle column section of the support column assembly 3; the reinforced connection assembly 8 is installed on the base body 101, and the reinforced connection assembly 8 is detachably connected to the top of the support column assembly 3.

[0080] For example, Figure 2 and Figure 3 As shown, 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 correspondingly, a reinforcing connection assembly 8 is connected to 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 into place by the first drive 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 restraint and tipping toward 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 drive assembly 4.

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

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

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

[0084] For example, Figure 3 As shown, the reinforcing connecting rod 801 can be a straight rod body or an F-shaped rod body, and the upper left end of the reinforcing connecting rod 801 is used to connect to the support column assembly 3. 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 assemblies 3 in different positions, and the two reinforcing connecting rods 801 are distributed on both sides of the support column assembly 3 along the X direction.

[0085] Similarly, if Figure 3 As shown, the first telescopic rod 401 is a linear telescopic rod, and the upper left end of the first telescopic rod 401 is used to connect to the support column assembly 3. 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 both sides of the support column assembly 3 along the X direction.

[0086] In summary, such a configuration can further reduce the risk of the support column assembly 3 losing restraint and tipping toward the left, and prevent the support column assembly 3 from tipping along the X direction. Based on this, it is helpful to ensure 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 pile driving operation, based on the above embodiment, the base 1 also includes a central support assembly 103, a first support assembly 104 and a second support assembly 105; the central support assembly 103 is located between the first support assembly 104 and the second support assembly 105; the base body 101 is vertically movable on the top of the central support assembly 103; the support leg 102 includes a support leg body 1021 and a track wheel 1022, the support leg body 1021 is a telescopic rod body and extends longitudinally, the first end of the support leg body 1021 is connected to the base body 101, and the second end is ball-connected to the track wheel 1022, and The track wheels 1022 of two support legs 102 are movably arranged in the horizontal direction at the corresponding first support assembly 104, and the track wheels 1022 of the remaining two support legs 102 are movably arranged in the horizontal direction at the corresponding second support assembly 105; it also includes a second drive assembly 9 and a third drive member 10, the first output end of the second drive assembly 9 is connected to the track wheel 1022 matched with the first support assembly 104, and the second output end of the second drive assembly 9 is connected to the track wheel 1022 matched with the second support assembly 105, which is used to drive the track wheel 1022 to move horizontally; the output end of the third drive member 10 is connected to the base body 101, which is used to drive the base body 101 to move vertically.

[0088] like Figure 3 and Figure 5 As shown, the support leg 102 is composed of a support leg body 1021 and a track wheel 1022. The support leg body 1021 extends along the Y direction, and the upper end of the support leg body 1021 is connected to the base body 101, and the lower end is connected to the track wheel 1022. In coordination, the pile driver is equipped with a first support assembly 104 and a second support assembly 105 that are independent of each other. The first support assembly 104 and the second support assembly 105 are arranged in parallel along the Z direction, and 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 two left support legs 102 slide with the tracks of the first support assembly 104 on the left, and the track wheels 1022 at the bottom of the two right support legs 102 slide with the tracks of the second support assembly 105 on the right.

[0089] The first support assembly 104 and the second support assembly 105 both include a base 1 and a track, the track is installed on the base 1, and the base 1 has a limiting portion, such as an L-shaped bending plate or a frame structure with a slot, etc., which is used to abut the track wheel 1022 to prevent the track wheel 1022 from detaching from the corresponding support assembly from the top opening of the limiting groove, so that when the support leg body 1021 is shortened to drive the track wheel 1022 to rise, it can drive the corresponding support assembly to rise.

[0090] Preferably, Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the base 1 is a linear base body with a limiting groove on 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 limiting plates extending toward each other, covering the top partial opening of the limiting groove, which are used to abut the track wheel 1022 to prevent the track wheel 1022 from detaching from the corresponding support assembly from the top opening of the limiting groove. With this arrangement, the weight of the support assembly is lower.

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

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

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

[0094] When in use, when the pile driver needs to move along the X direction, the support legs 102 are started to lift the central support assembly 103 and the base body 101, and then the second drive assembly 9 is started to drive the track wheel 1022 to move in the same direction along the X direction on the first support assembly 104 and the second support assembly 105.

[0095] When the pile driver needs to move along the Z direction, the support legs 102 are activated to lift the first support assembly 104 and the second support assembly 105 , and then the second drive assembly 9 is activated to drive the base body 101 to move along the Z direction on the central support assembly 103 .
