Technical Field

[0001] This utility model belongs to the field of steel pipe pile installation technology, and in particular relates to a pit excavation device for steel pipe pile installation. Background Technology

[0002] Steel pipe pile installation is an important foundation construction technology in building engineering, applicable to various geological conditions. During the installation process, it is first necessary to use equipment such as a pit digger for precise positioning and excavation to prepare suitable holes for the insertion of the steel pipe piles. The selection of the pit digger must be determined according to the specific geological conditions and design requirements to ensure that the excavation task can be completed efficiently while avoiding damage to the surrounding soil structure. Subsequently, the construction personnel will drive the prefabricated steel pipe piles into the predetermined depth using professional equipment, and strictly control their verticality and stability to ensure that they meet the engineering standard requirements.

[0003] The problem with existing technology is that existing equipment generally lacks an effective support design mechanism, resulting in significant instability during operation due to insecure fixing. Especially in complex terrain or uneven ground conditions, the insufficient contact area of ​​the equipment support and the lack of reliable fixing measures can easily lead to safety hazards such as equipment displacement, tilting, or even overall overturning.

A through hole 5 is opened at the top of the base plate 1. A lifting frame 6 is fixedly connected to the top of the base plate 1. The pit digger body 2 is placed on the right side of the lifting frame 6. The left side of the pit digger body 2 is slidably connected to the inside of the lifting frame 6. The position of the pit digger body 2 corresponds to the position of the through hole 5.

[0023] refer to Figure 1 Inside the lifting frame 6 is a lead screw 7. The bottom of the lead screw 7 is rotatably connected to the bottom of the lifting frame 6, and the top of the lead screw 7 extends through and out of the top of the lifting frame 6. The hole digger body 2 is threadedly connected to the surface of the lead screw 7. The top of the lifting frame 6 is fixedly connected to a motor 8, and the top of the lead screw 7 is fixedly connected to the output end of the motor 8.

[0024] By adopting the above solution, the automatic lifting and lowering of the main body 2 of the post hole digger can be achieved by setting the lead screw 7 and the motor 8, thereby accurately controlling the digging depth and improving work efficiency and ease of operation.

[0025] refer to Figure 2 and Figure 3 The base plate 1 has connecting grooves 9 on both the front and rear sides. An extension plate 10 is placed inside the connecting groove 9. The extension plate 10 is slidably connected to the inside of the connecting groove 9. A connecting frame 11 is fixedly connected to the bottom of the left and right sides of the extension plate 10. A fixing nail 12 is placed inside the connecting frame 11. The fixing nail 12 is slidably connected to the inside of the connecting frame 11. The top of the fixing nail 12 penetrates through and extends out of the top of the extension plate 10.

[0026] By adopting the above solution, the support range of the equipment can be expanded by setting the extension plate 10, the overall stability can be enhanced, and additional installation positions can be provided for the fixing nails 12, thereby adapting to the operation requirements under different terrain conditions.

[0027] refer to Figure 3 The surface of the connecting frame 11 is provided with irregular grooves 13, and the surface of the fixing nail 12 is fixedly connected with sliders 14, which are slidably connected to the inside of the irregular grooves 13.

[0028] By adopting the above solution, by setting the irregular groove 13 and the slider 14, it can be ensured that the fixing nail 12 is firmly locked in the connecting frame 11 when not in use, avoiding accidental detachment, while realizing rapid deployment and adjustment, improving operating efficiency and equipment stability.

[0029] refer to Figure 2 and Figure 4 The base plate 1 has a receiving block 15 fixedly connected to the front and rear sides of the top. The receiving block 15 has a receiving groove 16 inside. The top of the receiving groove 16 is fixedly connected to a spring 17. The bottom of the spring 17 is fixedly connected to a fixing rod 18. The bottom of the fixing rod 18 passes through and extends into the interior of the connecting groove 9. The top of the extension plate 10 has a fixing hole 19. The fixing hole 19 is used in conjunction with the fixing rod 18.

[0030] By adopting the above solution, a stable lock can be provided when the extension plate 10 is inserted into the connecting slot 9 by setting the fixing rod 18 and the spring 17, ensuring the stability of the equipment in the moving or non-operating state.

[0031] refer to Figure 4 Each of the fixed rods 18 is fixedly connected to a pull rod 20, and the top of each pull rod 20 extends through and out of the top of the receiving block 15.

[0032] By adopting the above solution, the locking state of the extension plate 10 can be quickly released by setting the pull rod 20, so that the user can easily pull the pull rod 20 to lift the fixing rod 18, thereby facilitating the pulling out or retracting operation of the extension plate 10.

[0033] refer to Figure 2 Each of the fixing pins 12 has a pull ring 21 on its top, and the side of the pull ring 21 away from the slider 14 is rotatably connected to the top of the fixing pin 12.

[0034] The above solution allows for easy adjustment of the height of the fixing nail 12 by setting the pull ring 21, thereby driving the slider 14 to move along the irregular groove 13 in the connecting frame 11. This allows the user to easily adjust the position of the fixing nail 12 or pull it out of the ground by simple lifting and rotating actions.

[0035] The working principle of this utility model:

[0036] In use, first move the device to a suitable working location, then fix the casters 4. Next, use the pull rod 20 to pull the fixing rod 18 upwards. When the fixing rod 18 moves out of the fixing hole 19, the fixing state of the extension plate 10 is released. Then, pull the extension plate 10 out along the connecting groove 9. After the extension plate 10 is pulled out, use the pull ring 21 to pull the fixing pin 12 upwards. The fixing pin 12 drives the slider 14 to move upwards. When the slider 14 moves to the top of the irregular groove 13, rotate the fixing pin 12 to drive the slider 14 upwards. 4. Rotate along the irregular groove 13. When the slider 14 rotates 90 degrees, stop rotating the fixing nail 12. At this time, the limit of the slider 14 is released. Then release the fixing nail 12. The fixing nail 12 will move down along the connecting frame 11. When the bottom of the fixing nail 12 contacts the ground, use a hammer or other tools to firmly drive the fixing nail 12 into the ground. After all the fixing nails 12 are installed, start the hole digger body 2 and the motor 8. The motor 8 drives the lead screw 7 to rotate, which drives the hole digger body 2 to move down along the lifting frame 6 to start the hole digging operation.

[0037] In summary, the pit excavation device for installing steel pipe piles, through the coordinated use of a base plate 1, excavator body 2, push handle 3, caster wheel 4, through hole 5, lifting frame 6, lead screw 7, motor 8, connecting groove 9, extension plate 10, connecting frame 11, fixing nail 12, irregular groove 13, slider 14, receiving block 15, receiving groove 16, spring 17, fixing rod 18, fixing hole 19, tie rod 20, and pull ring 21, solves the problem that existing equipment generally lacks an effective support design mechanism, resulting in significant instability during operation due to insecure fixing. Especially in complex terrain or uneven ground conditions, the insufficient contact area of ​​the equipment support and the lack of reliable fixing measures can easily lead to safety hazards such as equipment displacement, tilting, or even overall overturning.
