Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of pile driving equipment, in particular to a hydraulic pile driver device. Background Art
[0002] In the construction industry, pile foundations are crucial for ensuring building stability. Traditional pile foundation construction methods often rely on manual labor, which is not only inefficient but also difficult to ensure precision and safety.

These devices utilize the powerful power of hydraulic systems to mechanize pile foundation construction, significantly improving efficiency and precision.
[0003] However, existing hydraulic pile driver devices still have some shortcomings. When using small hydraulic pile drivers, construction workers need to hold the hydraulic pile driver in their hands before driving piles. During operation, the pile driver has poor stability and is prone to deflection or shaking, which affects the accuracy and safety of construction. Utility Model Content

DETAILED DESCRIPTION
[0015] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.
[0016] Example: A hydraulic pile driver device
[0017] like Figure 1 - As shown in Figure 2, a hydraulic pile driver device, the specific structure of which includes:
[0018] The bottom of the housing 1 is open, and a hydraulic cylinder 2 is fixedly mounted on the top surface of the inner wall of the housing 1. A connecting rod 3 is fixedly mounted on the lower end of the movable rod of the hydraulic cylinder 2, and a movable block 4 is fixedly mounted on the lower end of the connecting rod 3. The movable block 4 is slidably mounted in the housing 1 through a limit assembly, enabling stable vertical movement. A support plate 5 is fixedly mounted on the bottom of the outer periphery of the housing 1 to provide stable basic support. A circular ring 6 is slidably mounted on the outer periphery of the housing 1, and a number of evenly distributed insertion rods 7 are fixedly mounted on the bottom surface of the circular ring 6. By raising and lowering the circular ring 6, the insertion rods 7 can be inserted into the ground for pile foundation construction. The top surface of the support plate 5 has a number of through holes 8 corresponding to the insertion rods 7, allowing the insertion rods 7 to penetrate for further fixation. Stoppers 9 are fixedly mounted on the upper portion of each side of the housing 1 to limit the maximum rise position of the circular ring 6, ensuring that the top surface of the circular ring 6 can contact the bottom surface of the stopper 9, thereby preventing excessive lifting.
[0019] The above working principle: When the device is performing piling, the hydraulic cylinder 2 drives the connecting rod 3 and the moving block 4 to move downward, so that the moving block 4 presses the pile foundation downward to perform the piling operation. When in use, the ring 6 and the insertion rod 7 can be lowered to insert the insertion rod 7 into the soil, thereby achieving reinforcement and stabilization of the casing 1 through the mutual cooperation between the insertion rod 7 and the support plate 5, avoiding the deflection or shaking of the device during construction, and improving the accuracy and safety of construction.
[0020] The limiting assembly includes a slider 10. Limiting slots 11 are defined at the lower portions of both sides of the inner wall of the housing 1. Sliders 10 are slidably mounted within the limiting slots 11. The inner sides of the sliders 10 are fixedly connected to the opposite side of the movable block 4. When the movable block 4 moves up and down under the drive of the hydraulic cylinder 2, the sliding of the sliders 10 within the limiting slots 11 ensures a stable motion trajectory of the movable block 4, preventing deflection or shaking, and improving construction accuracy and safety.
[0021] A plurality of guide tubes 12 corresponding to the through holes 8 are fixedly mounted on the top surface of the support plate 5. The guide tubes 12 are coaxially arranged with the corresponding through holes 8. The lower ends of the insertion rods 7 extend through the corresponding guide tubes 12 and into the corresponding through holes 8. The guide tubes 12 provide a precise insertion path for the insertion rods 7, ensuring that the insertion rods 7 can accurately pass through the through holes 8 and enter the soil, thereby improving construction accuracy and efficiency.
[0022] The insert rod 7 is provided with a screw sleeve 13, and the lower part of the outer periphery of the insert rod 7 is provided with an external thread 14 that cooperates with the screw sleeve 13. The screw sleeve 13 is tightened on the external thread 14 of the insert rod 7 by rotation, which can further fix the position of the insert rod 7 in the soil, prevent it from loosening, and enhance the stability of the pile foundation.
[0023] The lower end of the rod 7 is a tapered structure. The tapered lower end of the rod 7 is easier to penetrate the soil, reducing construction resistance and energy consumption, improving construction efficiency, and increasing the contact area with the soil, thereby improving the bearing capacity of the pile foundation.
[0024] In the interpretation of the present invention, it should be noted that the terms indicating orientation are only for the convenience of description and understanding, and are not the only limitation on the installation position of specific technical features, and do not exclude other possible installation methods.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
