Description

Technical Field

[0002] In the field of precast pile construction, the hammer driving method is widely used due to its high efficiency. However, traditional hammer driving devices have exposed many technical shortcomings when dealing with the construction of precast piles of different depths and types, which seriously restricts the improvement of construction efficiency and quality.

[0003] Traditional hammer-driven pile driving devices rely on extremely rudimentary methods for adjusting the hammering height, often involving manual disassembly, addition of components, or overall adjustment of the equipment height. For example, when constructing precast piles at different depths, workers must use cranes to lift the hammering components, manually add or remove support pads, or adjust the length of the support rods. This entire process requires multiple people working together, and a single adjustment can take several hours. This cumbersome procedure not only severely delays construction progress but also leads to prolonged equipment downtime. Therefore, these problems need to be addressed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 The present invention relates to a hammer-driven pile driving device for precast piles, comprising a base plate 1, a mounting block fixedly connected to the base plate 1, a mounting plate fixedly connected to the top of the mounting block, a rope take-up seat mounted on the mounting plate, and a rope 3 mounted on the rope take-up seat, which facilitates precise control of the lifting height of the hammering component; guide rails 13 are fixedly connected to both sides of the top of the mounting block, which facilitates the smooth and accurate movement of the adjusting seat 2, avoiding deviation or jamming, and improving the accuracy and efficiency of the hammering component position adjustment; the mounting block is provided with an adjusting component, and two telescopic support rods 6 are welded to one end of the top of the base plate 1, which facilitates flexible height adjustment according to construction needs, adapting to precast pile construction of different depths and types; the hammering component is slidably mounted on the two telescopic support rods 6, and a fixing plate is welded to the other end of the top of the base plate 1, with support plates 4 hinged to both sides of the fixing plate, which enhances the stability of the hammering component during hammering and prevents it from shaking or deviating; wheels 9 are mounted on the bottom of the base plate 1, which significantly improve the mobility and flexibility of the device.

[0020] In this invention, multiple insertion ports are equidistantly provided on the two telescopic support rods 6. A support post for support is inserted into one insertion port. A hook 10 is attached to one end of the rope 3. The hammering component is connected to the rope 3 through the hook 10. The rope 3 abuts against the side wall of the support post. A rocker arm for winding the rope is provided at one end of the rope winding seat. The hook 10 ensures that the hammering component will not detach from the rope 3 during lifting and lowering, ensuring construction safety. Connecting plates 5 are threaded to both ends of the support post. The other end of the connecting plate 5 is rotatably connected to the support plate 4. The connecting plate 5 ensures that the support post is firmly fixed, providing a reliable support point for the rope 3 and ensuring the stability of the lifting and fixing of the hammering component. The adjusting component includes a screw rod 11 located on the inner wall of the top of the mounting block. A matching gear is fixed to one end of the screw rod 11. A linkage rod is threaded to the screw rod 11. Adjusting seats 2 are fixed to both ends of the linkage rod. The seat 2 is slidably connected to the guide rail 13. A motor is installed on the outer wall of the mounting block. The output end of the motor is equipped with a transmission gear, which meshes with the mating gear. The lead screw 11 facilitates precise control of the movement distance and position of the adjusting seat 2, thereby accurately adjusting the horizontal position of the hammering component. The side wall of the support plate 4 is equipped with a hinge seat 12. A movable rod is rotatably mounted on the adjusting seat 2. One end of the movable rod is hinged to the hinge seat 12. The hinge seat 12 facilitates flexible adjustment of the angle of the support plate 4, ensuring that the support plate 4 can be adjusted synchronously when the adjusting seat 2 moves, maintaining the stability and accurate striking angle of the hammering component. The hammering component includes a rotating seat mounted on the telescopic support rod 6. A pneumatic pump 7 is installed on the rotating seat. The extended end of the pneumatic pump 7 is screwed onto a hammering block 8. The pneumatic pump 7 provides a stable and adjustable power output, allowing the hammering block 8 to strike the precast pile with appropriate force, improving the pile driving efficiency.

[0021] Working Principle: When using this utility model, during precast pile construction, the construction personnel can use the pushing device and the wheels 9 at the bottom of the base plate 1 to move the hammer-driven pile device to the target pile position. After reaching the designated position, according to the position of the precast pile and construction requirements, the motor on the outer wall of the mounting block is started. The transmission gear at the output end of the motor drives the matching gear at one end of the lead screw 11 to rotate. When the lead screw 11 rotates, the connecting rod connected to it will generate linear motion through the threaded transmission, thereby driving the adjusting seat 2 to slide horizontally on the guide rail 13. While the adjusting seat 2 moves, the support plate 4 is driven to adjust the angle through the connection between the movable rod and the hinge seat 12, thereby achieving precise positioning and angle adjustment of the hammering component in the horizontal direction, ensuring that it can be accurately aligned with the precast pile. Then, after positioning is completed, the rocker arm of the rope-retracting seat is rotated to wind and retract the rope 3. The rope 3 lifts the hammering component through the hook 10. When the hammering component is raised to the appropriate position... At the designated height, insert the abutment post into the corresponding insertion port on the telescopic support rod 6. The rope 3 abuts against the side wall of the abutment post, temporarily fixing the hammering component and keeping it suspended in the air to prepare for hammering. Then, release the rope 3, and the hammering component falls under the action of gravity. At this time, the air pump 7 on the operating seat starts, outputting powerful air pressure to push the hammering block 8 to accelerate downward. The hammering block 8 strikes the top of the precast pile at extremely high speed, converting air pressure energy into mechanical energy and generating a huge impact force. This impact force overcomes the resistance of the soil to the precast pile, causing the precast pile to gradually sink into the ground. Finally, when it is necessary to adjust the hammering height to adapt to the construction of precast piles of different depths or types, the height of the telescopic support rod 6 can be changed by adjusting the components, and the insertion port can be re-selected to insert into the abutment post, changing the height of the support point of the rope 3, thereby adjusting the falling height and hammering force of the hammering component. This concludes the use of the hammering pile driving device for precast piles.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
