The static pressure hammering structure 3 can hammer and sink the precast pile or static pressure pile according to the soil quality, the static pressure hydraulic rod group 4 provides power for static pressure pile sinking, the hammer hydraulic rod 6 provides power for hammering pile sinking, the load block 5 plays a role of connecting the static pressure hydraulic rod group 4 and the hammer hydraulic rod 6, and also increases its own load for static pressure pile sinking, the clamping structure 8 and the conveying structure 19 cooperate with each other to accurately move the precast pile to the bottom of the static pressure hammering structure 3.

[0027] The clamping structure 8 includes a clamping platform 9, a working groove 10 opened on the outside of the clamping platform 9, a pushing hydraulic rod 11 arranged in the working groove 10, a connecting block 12 arranged at the telescopic end of the pushing hydraulic rod 11, a clamping hydraulic rod 13 arranged on the inside of the connecting block 12, and a clamping block 14 arranged at the telescopic end of the clamping hydraulic rod 13. The working groove 10 facilitates the contraction and pushing of the pushing hydraulic rod 11, and the connecting block 12 is used to connect the pushing hydraulic rod 11 and the clamping hydraulic rod 13.

[0028] The conveying structure 19 includes a retractable platform 15, a conveying hydraulic rod 16 arranged on the inner side of the retractable platform 15, and a movable chassis 17 arranged at the retractable end of the conveying hydraulic rod 16. The retractable platform 15 is convenient for retracting and storing the conveying hydraulic rod 16, and the movable chassis 17 is convenient for placing and moving prefabricated piles.

[0029] The movable chassis 17 includes an "E"-shaped support base 18 and a plurality of metal rollers 20 arranged below the opening of the "E"-shaped support base 18. The "E"-shaped support base 18 provides a perfect support to prevent the metal rollers 20 from being deformed due to excessive pressure on both sides.

[0030] A driving motor 21 is provided at the four end corners of the lower end surface of the main body 1, and a supporting connection block 22 is provided between the two driving motors 21 on the same side. A rotatably connected rotating support shaft 23 is provided on the outer side of the supporting connection block 22. The driving motor 21 provides moving power for the device, and the supporting connection block 22 is used to connect and fix the driving motor 21 and the main body 1.

[0031] Both the driving motor 21 and the rotating support shaft 23 are provided with movable hubs 24, and several movable hubs 24 are wrapped by metal tracks 25. Metal clips 26 are provided on the inner and outer sides of the metal tracks 25. The metal tracks 25 increase the contact area and reduce the pressure to prevent them from getting stuck at the construction site. The metal clips 26 prevent the movable hubs 24 from detaching from the metal tracks 25 due to loosening.

[0032] A connection block limiting strip 27 for limiting support is provided on the side where the clamping platform 9 contacts the connection block 12, and anti-slip convex strips 28 are provided on the inner side of the clamping block 14. The connection block limiting strip 27 supports and limits the connection block 12 to prevent the connection block 12 from breaking, and the anti-slip convex strips 28 make the clamping of the precast pile more stable.

[0033] A rubber noise reduction block 29 is provided on the lower surface of the striking hammer 7, and a weight balance block 30 is provided on the upper surface of the main body 1 at one end away from the clamping structure 8. The rubber noise reduction block 29 reduces the noise when the hammer drives the pile, and the weight balance block 30 maintains the front and rear balance of the entire device.

[0034] like Figure 1-Figure 7As shown, the principle of the hammer pile driving device for precast piles provided in this embodiment is as follows: when using the device, static pressure pile driving or hammer pile driving should be selected according to the hardness of the soil, and then the device should be moved to the construction position, and then the movable chassis 17 should be moved to the bottom of the clamping structure 8 at the front end of the device through the conveying hydraulic rod 16. At this time, the precast pile is placed on the movable chassis 17, and then the clamping block 14 is controlled by the clamping hydraulic rod 13 to clamp and support the precast pile, and then the push hydraulic rod 11 and the conveying hydraulic rod 16 are contracted at the same speed and the precast pile is clamped and moved to the bottom of the static pressure hammering structure 3. At this time, the movable chassis 17 will retract to the initial position under the action of the conveying hydraulic rod 16, and the precast pile will slide down vertically under the action of the clamping structure 8 until it touches the ground;

[0035] When using static pressure pile sinking, the striking hammer 7 contacts the top of the precast pile by hammering the hydraulic rod 6, and at the same time the static pressure hydraulic rod group 4 will slowly statically press the precast pile, and the hammering hydraulic rod 6 will also slowly extend to assist static pressure, and then the clamping structure 8 will slowly loosen when the top of the precast pile is almost level with the clamping block 14, and shrink to the initial position by pushing the hydraulic rod 11;

[0036] When using a hammer to sink a pile, the hammer 7 will use the hammer hydraulic rod 6 to perform gravity strikes on the top of the precast pile. At the same time, the static pressure hydraulic rod group 4 will slowly descend, so that when the precast pile moves downward, the static pressure hammer structure 3 will also move downward as a whole, so that the striking effect is always at the optimal distance. Then the clamping structure 8 will slowly loosen when the top of the precast pile is almost level with the clamping block 14, and shrink to the initial position by pushing the hydraulic rod 11.

[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0039] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
