[0025] Next, we will combine the appendix Figure 1-9 A specific embodiment of the present invention will be described in detail below.

[0026] A pre-planted pile vibratory hammer with rotating pile-holding function, as shown in the attached... Figure 1 As shown, the device includes a vibration isolation device 1, a vibration device 2, a rotating device 3, and a clamping device 4. The vibration device 2 is disposed inside the vibration isolation device 1 and is rotatably connected to the vibration isolation device 1 through the rotating device 3. The vibration device 2 is connected to the clamping device 4 through a connecting device 5. The clamping device 4 is used to clamp the pile body 91. That is, by rotating the rotating device 3, the vibration device 2 is rotated, thereby causing the clamping device 4 at the front end of the vibration device 2 to rotate, so that the horizontal pile body 91 is in a vertical state. Then, the vibration device 2 is started to perform a pile driving operation on the pile body 91.

[0027] As attached Figure 2 As shown, the vibration device 2 includes an excitation box 21. Inside the excitation box 21, there are two eccentric shafts 22 rotating in opposite directions. The eccentric shafts 22 are integrally manufactured, which improves the overall performance of the eccentric shafts 22. A driver 23 is provided at the upper end of the excitation box 21.

[0028] The output end of the driver 23 is provided with a pulley 24, and the front end of one of the eccentric shafts 22 inside the vibration box 21 is also provided with a pulley 24. The eccentric shaft 22 is set inside the vibration box 21 through a bearing 25, and a gear 26 is provided on the eccentric shaft 22. The two gears 26 rotate in opposite directions. The gears 26 are connected to the eccentric shaft 22 through a key connection, and the two pulleys 24 are connected by a belt. That is, by starting the driver 23, the pulleys 24 are driven to rotate, thereby causing the eccentric shaft 22 inside the vibration box 21 to rotate. Due to the gears 26, the eccentric shaft 22 inside the vibration box 21 can rotate in opposite directions, so that the entire device produces vertical up-and-down vibration, thereby achieving the purpose of pile driving.

[0029] Preferably, the driver 22 can be hydraulically driven or driven by an electric motor; when the driver 22 is driven by an electric motor, the driver 22 adopts a four-stage anti-vibration motor, which increases the speed of the driver 22 by 50%, which helps to reduce the weight, volume and cost of the driver, and extends the advantages of the vibratory hammer.

[0030] The rotating device 3 includes pins 31 at both ends of the vibration box 22. The pins 31 are rotatably connected to the inner sides of the vibration isolation device 1. One end of the pin 31 is fixedly connected to a rotating cylinder 32, which is fixed to one side of the vibration isolation device 1. That is, by controlling the rotation of the rotating cylinder 32, the pins 31 are rotated, thereby causing the vibration box 21 to rotate. It should be noted that when the pins 31 rotate, they will not interfere with the eccentric shaft 22 inside the vibration box 21; and the rotating cylinder 32 will self-lock after rotating 90°. Preferably, the rotating cylinder 32... It can be a swing cylinder or a gear / rack cylinder. When the rotating shaft cylinder 32 is a gear / rack cylinder, a gear is provided at the upper end of the rack. By driving the gear to rotate, it meshes with the rack below. When it travels to both ends of the rack, the gear stops rotating, i.e., it is self-locking. When the rotating shaft cylinder 32 is a swing cylinder, the upper end of the swing cylinder is fixedly connected to the upper end of the vibration isolation device 1, and the lower end is connected to the rotation point of the vibration device 2. That is, it drives the cylinder on the swing cylinder to extend its length, thereby causing the vibration device 2 to rotate. When it reaches the designated position, it stops driving, achieving the purpose of self-locking.

[0031] As described above, the clamping device is used to clamp the pile body 91. In actual operation, the applicant found that the pile body 91 is divided into solid pile body and circular pile body, that is, the clamping device 4 corresponding to each different type of pile body 91 is different. Therefore, the applicant has taken the following measures:

[0032] When the pile body 91 is a solid pile body, as shown in the attached... Figure 3 As shown, the clamping device 4 includes symmetrically arranged clamping bases 41. The clamping bases 41 are detachably installed with the connecting device 5. The center of each clamping base 41 is hollow. The two clamping bases 41 are evenly provided with mounting holes 42. A telescopic cylinder 43 is provided outside the mounting holes 42. A pile clamping block 44 is provided at the front end of the telescopic cylinder 43. The front end of the pile clamping block 44 is arc-shaped. That is, when the solid pile extends into the center of the clamping base 41, the telescopic cylinder 43 is controlled at the same time so that the pile clamping blocks around it clamp and fix the solid pile inside.

[0033] However, through practice, the applicant has found that if all telescopic cylinders are controlled simultaneously for clamping, it will lead to two problems: first, energy waste; second, increased production costs. Therefore, the applicant has adopted the following solution: the clamping base 41 is evenly provided with five mounting holes 42. The rear ends of the two bottom-side clamping blocks 44 do not have telescopic cylinders 43, while the other three clamping blocks 44 do. That is, the lower surface of the pile to be clamped is flush with the upper surface of the clamping blocks 44 on both sides of the bottom of the clamping base 41 using pads. Then, the pile is inserted into the clamping base 41, and the telescopic cylinders 43 are controlled to clamp and fix it. It should be noted that in this application, the mounting holes 42 are evenly set to five, and the number of clamping blocks 44 is also five. This arrangement allows the clamping blocks 44 to apply force more evenly to the solid pile, preventing uneven force on the pile and damage.

[0034] Preferably, two clamping bases 16 are provided;

[0035] When the pile body 91 is a circular ring pile body, as shown in the attached... Figure 9 As shown, the clamping device 4 includes a connecting base 45 that is detachably installed with the connecting device 5. The front end of the connecting base 45 is provided with a clamp 46, which is used to fix the pile body 91. This technology is existing technology and will not be described in detail here.

One end of the swing cylinder 79 is fixed at the upper end of the Y-shaped fixing frame by a first fixing plate, and the other end of the swing cylinder 79 is fixed to the side of the excitation box 21. Locking plates 92 are provided on the inner side of the Y-shaped fixing frame 71, and locking cylinders 93 are fixed on one side of the locking plate 92, which can maintain the stability of the vibratory hammer and also fix the shape of the vertical pile.

[0039] It adopts a rotatable single-axis suspension with a built-in combined butterfly spring, which maximizes the protection of the vibratory hammer while increasing the lifting force;

[0040] like Figure 8As shown, when the vibration isolation device 1 uses rubber block vibration isolation 8, the rubber block vibration isolation 8 includes connecting frames 81 arranged on both sides of the excitation box 21. The two ends of the pin shaft 31 are rotatably connected to the two inner sides of the connecting frame 81. A mounting frame 82 is provided at the upper end of the excitation box 21. The mounting frame 82 and the connecting frame 3 are connected by rubber blocks 83. The rubber blocks 83 are arranged in two rows, with more than three in each row. The mounting surface of the rubber blocks 83 is parallel to the axis of the eccentric shaft 2. The rubber blocks 83 are in the shape of "I" and have mounting holes. The mounting frame 82 is fixedly connected to the connecting frame 81 by bolts. A second fixing plate 84 is provided on one side of the connecting frame 81. The second fixing plate 84 is used to fix the rotating shaft cylinder 32. The rotating shaft cylinder 32 is a gear / rack cylinder.

[0041] Each vibration isolation device 1 is equipped with a hanging ring 9 at its upper end. The entire vibratory hammer is lifted by hooking the hanging ring 9 with an external hook.
