Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention discloses a portable pile driving device, including a frame 1, a driving mechanism 2 is fixedly installed on the front side of the frame 1, guiding mechanisms 3 are fixedly installed on the front sides of the left and right sides of the driving mechanism 2 on the front side of the frame 1, a mounting plate 4 is fixedly installed between the front sides of the driving mechanism 2 and the guiding mechanism 3, a mounting bracket 5 is fixedly installed on the front side of the mounting plate 4, a rotary drilling mechanism 6 is fixedly installed on the upper surface of the mounting bracket 5, support frames 7 are fixedly installed at the lower left and right edge positions on the front and rear sides of the frame 1, and fixed support legs 8 are fixedly installed at the front edge positions on the lower surfaces of the front support frames 7, and movable support legs 10 are installed on the rear support frames 7 near the rear edge positions through adjusting mechanisms 9, rollers 11 are fixedly installed on the rear sides of the support frames 7, and handles 12 are fixedly installed at the upper left and right edge positions near the rear side of the frame 1.

[0022] Specifically, the driving mechanism 2 includes a first fixing block 201 and an electric linear module 202. The first fixing block 201 is fixedly installed at the upper and lower edge positions in the middle of the front side of the frame 1, and the electric linear module 202 is fixedly installed between the upper and lower first fixing blocks 201. The front side of the sliding table of the electric linear module 202 is connected and fixed to the mounting plate 4.

[0023] In this embodiment, the first fixing block 201 is used to install the electric linear module 202, and the sliding table of the electric linear module 202 drives the rotary drilling mechanism 6 on the mounting bracket 5 to move up and down through the mounting plate 4.

[0024] Specifically, the guiding mechanism 3 includes a second fixing block 301, a guiding rod 302 and a sliding block 303. The second fixing block 301 is fixedly installed at the upper and lower edge positions of the front side of the frame 1, and a guiding rod 302 is fixedly installed between the upper and lower second fixing blocks 301. The guiding rod 302 is sleeved with a sliding block 303, and the front side of the sliding block 303 is fixedly connected to the rear side of the mounting plate 4.

[0025] In this embodiment, the sliding block 303 moves up and down on the guiding rod 302 along with the mounting plate 4, achieving the effect of guiding the up and down movement of the mounting frame 5 on the mounting plate 4, that is, guiding the up and down movement of the rotary drilling mechanism 6, so that the drilling position of the rotary drilling mechanism 6 is accurate.

[0026] Specifically, the rotary drilling mechanism 6 includes a motor 601, a connecting component 602 and a helical drill bit 603. The motor 601 is installed on the upper surface of the mounting frame 5, and the lower surface of the output shaft of the motor 601 is provided with a helical drill bit 603 through the connecting component 602.

[0027] In this embodiment, the output shaft of the motor 601 drives the connecting component 602 to rotate, so that the connecting component 602 drives the helical drill bit 603 to rotate for drilling and piling.

[0028] Specifically, the connecting component 602 includes an internal hexagonal sleeve 6021, a pin hole 6022 and a pin shaft 6023. The internal hexagonal sleeve 6021 is fixedly installed on the lower surface of the output shaft of the motor 601. Pin holes 6022 are formed in the left and right side walls of the internal hexagonal sleeve 6021 and on the helical drill bit 603, and a pin shaft 6023 is arranged in the pin hole 6022.

[0029] In this embodiment, the pin hole 6022 and the pin shaft 6023 cooperate to make the internal hexagonal sleeve 6021 and the helical drill bit 603 a detachable structure. When the depth of the helical drill bit 603 is insufficient, an extension rod can be added between the helical drill bit 603 and the internal hexagonal sleeve 6021 so that the helical drill bit 603 can reach the required depth.

[0030] Specifically, the adjusting mechanism 9 includes a threaded sleeve 901, a bolt rod 902 and a bearing 903. The threaded sleeve 901 is embedded in the rear support frame 7. The bolt rod 902 is threadedly installed in the threaded sleeve 901, and the lower surface of the bolt rod 902 is fixedly connected to the movable support leg 10 through the bearing 903.

[0031] In this embodiment, the bolt rod 902 rotates and moves downward in the threaded sleeve 901, so that the bolt rod 902 drives the movable support leg 10 to move downward through the bearing 903, making the movable support leg 10 flush with the fixed support leg 8.

[0032] Specifically, reinforcing rods 13 are fixedly installed between the front and rear side surfaces of the frame 1 and the upper surfaces of the front and rear support frames 7.

[0033] In this embodiment, the reinforcing rods 13 connect the support frame 7 to the frame 1, enhancing the strength of the support frame 7.

[0034] During use, the operator holds the handle 12 and tilts the frame 1 towards the roller 11. At this time, both the fixed support leg 8 and the movable support leg 10 are disengaged from the ground, facilitating the movement of the pile driving device. After the pile driving device is moved to the desired position, the frame 1 is reset, and the fixed support leg 8 supports on the ground. Then, by rotating the bolt rod 902 in the threaded sleeve 901 of the adjustment mechanism 9 downward, the bolt rod 902 drives the movable support leg 10 to move downward through the bearing 903, making the movable support leg 10 flush with the fixed support leg 8, that is, keeping the frame 1 in a horizontal state. The output shaft of the motor 601 in the rotary drilling mechanism 6 drives the connection assembly 602 to rotate, and the connection assembly 602 drives the helical drill bit 603 to rotate for drilling and pile driving. Then, the electric linear module 202 of the driving mechanism 2 drives the slide table to drive the rotary drilling mechanism 6 on the mounting frame 5 to move up and down through the mounting plate 4, and the mounting plate 4 drives the slider 303 in the guiding mechanism 3 to move downward on the guiding rod 302, achieving the effect of guiding the downward movement process of the rotary drilling mechanism 6, making the position of the pile drilled by the rotary drilling mechanism 6 accurate. When the helical drill bit 603 cannot reach the required depth, the pin hole 6022 and the pin shaft 6023 cooperate to make the internal hexagonal sleeve 6021 and the helical drill bit 603 a detachable structure, so that the helical drill bit 603 is separated from the motor 601 through the connection assembly 602, and the driving mechanism 2 drives the motor 601 to move upward and reset. When the depth of the helical drill bit 603 is insufficient, an extension rod can be added between the helical drill bit 603 and the internal hexagonal sleeve 6021 to enable the helical drill bit 603 to reach the required depth. This pile driving device is small in size, convenient to operate, can be completed only by manual labor, easy to control the depth, reduces cost investment, makes it possible to drive piles in a small space, and has strong practicability.

[0035] In summary, this portable pile driving device is small in size, convenient to operate, can be completed only by manual labor, the position of the driven pile is accurate, the depth is easy to control, the cost investment is reduced, it is possible to drive piles in a small space, and it is convenient to move the pile driving device, with strong practicability.
