The pile hammer part 100 and the extension parts 200 respectively arranged on both sides of the pile hammer part 100 make the overall shape of the pile driving hammer head be an inverted U shape. When driving a pile, the pile column 910 is located in the groove of the pile driving hammer head, and the pile column 910 is restricted to move in the groove, which can prevent the position of the pile column 910 from shifting and improve the installation accuracy of the pile column 910; while keeping the height of the pile hammer part 100 unchanged, the extension parts 200 increase the overall weight of the pile driving hammer head and improve the pile driving pressure effect of the pile driving hammer head; the width of the extension part 200 gradually decreases from top to bottom, making the weight of the pile driving hammer head be heavier at the upper end and lighter at the lower end. Therefore, the center of gravity of the pile driving hammer head is biased towards the upper end of the pile driving hammer head, and further makes the center position of the pile driving hammer head closer to the abutting position of the pile column 910 and the pile hammer part 100. The center of gravity is close to the pile column 910, enabling the pile driving hammer head to better press the pile column 910 during operation and improving the pressing effect of the pile driving hammer head.

[0051] Furthermore, through the overall shape design of the pile driving hammer head, the center of gravity can be set at a position close to the lower part of the pile hammer part 100, and the center of gravity position is close to the abutting position of the pile column 910 and the pile hammer part 100.

[0052] In some embodiments, multiple layers of steps 210 are provided on the side of the extension part 200 away from the middle of the pile hammer part 100, and the height of the steps 210 gradually decreases from top to bottom. The stacked steps 210 can make the width of the pile driving hammer head gradually decrease from top to bottom, and the weight changes accordingly, making the center of gravity of the pile driving hammer head biased towards the upper part.

[0053] The height of the step 210, it can be understood that it is from the side of the extension part 200 away from the middle of the pile hammer part 100 to the side close to the middle of the pile hammer part 100.

[0054] Furthermore, an inclined surface or an arc surface is provided on the side of the extension part 200 away from the middle of the pile hammer part 100, and the thickness of the step 210 gradually decreases from top to bottom. The extension part 210 provided with the inclined surface or the arc surface can make the width of the pile driving hammer head gradually decrease from top to bottom, and the weight changes accordingly, making the center of gravity of the pile driving hammer head biased towards the upper part.

[0055] In some embodiments, a flat straight surface 220 is provided on the side of the extension part 200 close to the middle of the pile hammer part 100. The flat straight surface 220 plays a guiding role for the pile column 910, enabling the pile column 910 to be restricted to move in the inverted U-shaped groove, which is convenient for use.

[0056] In some embodiments, the indoor hammer pile driver further includes a guide portion 300, which is provided with an extension portion 200 and / or a pile hammer portion 100. The guide portion 300 is provided with a guide groove 310, which is configured to cooperate with a guide post 610 of the indoor hammer pile driver body. The guide portion 300 cooperates with the indoor hammer pile driver body to guide the direction of the pile driving hammer head, enabling the pile driving hammer head to move stably in the vertical direction and ensuring pile driving accuracy.

[0057] In some embodiments, the connecting portion 400 includes a bearing member 410 disposed in the middle of the pile hammer unit 100 and a connector 420 disposed on the pile hammer unit 100.

[0063] The first traction mechanism 700 is provided on the frame 600;

[0064] The piling hammer head, the first traction mechanism 700 is used to pull the piling hammer head.

[0065] According to an embodiment of the present utility model, by setting it in this way, at least the following effects can be achieved. The pile hammer part 100 and the extension parts 200 respectively arranged on both sides of the pile hammer part 100 make the whole pile driving hammer head in an inverted U shape. When driving a pile, the pile column 910 is located in the groove of the pile driving hammer head, and the pile column 910 is restricted to move within the groove, which can prevent the position of the pile column 910 from shifting and improve the installation accuracy of the pile column 910; while keeping the height of the pile hammer part 100 unchanged, the extension parts 200 increase the overall weight of the pile driving hammer head, improving the pile driving pressure effect of the pile driving hammer head; the width of the extension parts 200 gradually decreases from top to bottom, making the weight of the pile driving hammer head heavier at the upper end and lighter at the lower end. Therefore, the center of gravity of the pile driving hammer head is biased towards the upper end of the pile driving hammer head, and further makes the center position of the pile driving hammer head closer to the abutting position of the pile column 910 and the pile hammer part 100. With the center of gravity close to the pile column 910, the pile driving hammer head can better press the pile column 910 during operation, improving the crimping effect of the pile driving hammer head; the first traction mechanism 700 is used to drive the pile driving hammer head to move in the up and down direction, enabling the pile driving hammer head to drive piles for the pile column 910.

[0066] In some embodiments, it further includes a hook 810 and a second traction mechanism 820. The second traction mechanism 820 is arranged on the frame 600, and the second traction mechanism 820 is used to traction the hook 810. The hook 810 and the second traction mechanism 820 cooperate to enable the hook 810 to hang items such as the pile column 910; secondly, the hook 810 can be hooked onto other objects, so as to traction the whole frame 600 to move by shortening the driving rope.

[0067] It can be understood that rolling columns are arranged below the frame 600, and the fixed columns are rotatably arranged on the frame 600, enabling the frame 600 to move. The indoor pile hammering machine does not need to be provided with moving parts, and can move in the front and back directions through the hook 810 and the second traction mechanism 820 or move by means of a forklift, etc.

[0068] In some embodiments, the frame 600 is provided with guide columns 610, and the guide columns 610 extend in the up and down direction. The guiding part 300 and the indoor pile hammering machine body cooperate to guide the direction of the pile driving hammer head, enabling the pile driving hammer head to stably move in the up and down direction and ensuring the pile driving accuracy of the pile driving hammer head.

[0069] In some embodiments, it further includes a limiting part 900, and the limiting part 900 can completely penetrate the frame 600 and partially or completely insert into the pile driving hammer head. When the indoor pile hammering machine is not in use, the limiting part 900 can prevent the pile driving hammer head from moving downward, effectively relieving the pressure on the first traction mechanism 700.
