Description

Technical Field

[0001] The utility model relates to the technical field of pile-driving machinery, in particular to a fixing device for a pile driving and pulling machine. Background Art

[0002] A pile driver is a pile-driving machine that uses vibration, static force or hammering to drive piles into or out of the ground. In pile construction, vibration is the most common method. During operation, the vibration pile driver is fixed to the pile head and suspended under the hook through a spring absorber and rigging. When the pile driver is started, the vibration generated by the vibrator causes the pile body and the soil to resonate, destroying the soil structure and reducing the friction between the pile body and the soil.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0046] This embodiment provides a pile driver fixing device for fixing a pile driver fixed on the upper end of a pipe pile. The pipe pile to be driven into or pulled out of the ground is inserted into the pile hole, and the pile driver is fixed on the upper end of the pipe pile.

[0047] like Figure 1 As shown, the fixing device of the pile driver comprises a fixing seat 1, a fixing structure 2 and a clamping structure 3. There are multiple fixing structures 2, which are arranged at intervals on the fixing seat 1. A plurality of fixing holes are arranged around the pile hole, and the plurality of fixing structures 2 are inserted into the plurality of fixing holes one by one to fix the device on the ground. The pile driver passes through the through hole 10 provided on the fixing seat 1, and the clamping structure 3 provided on the fixing seat 1 is clamped on the outside of the pile driver to ensure the stability of the pile driver during operation.

[0048] Specifically, in this embodiment, two fixing structures 2 are provided, and the two fixing structures 2 are respectively arranged at two ends of the fixing base 1 to enhance the stability of the fixing base 1 fixed to the ground.

[0049] Optionally, refer to Figure 2The fixing structure 2 includes a first driving member 21, a first transmission assembly 22 and a plurality of insertion rods 23. The first driving member 21 is fixed on the fixing seat 1, and the output end of the first driving member 21 is connected to the plurality of insertion rods 23 through the first transmission assembly 22, and the plurality of insertion rods 23 are circumferentially arranged on the first transmission assembly 22. Under the drive of the first driving member 21, the plurality of insertion rods 23 can be inserted into the soil layer around the fixing hole, further enhancing the stability of the fixing of the device.

[0050] Exemplarily, the first driving member 21 is a motor commonly used in the art, and the output end of the first driving member 21 can rotate clockwise or counterclockwise. Figure 3 When the first driving member 21 rotates clockwise, it can drive the multiple insertion rods 23 to be inserted into the side wall of the fixing hole; when the first driving member 21 rotates counterclockwise, it can drive the multiple insertion rods 23 to be pulled out from the side wall of the fixing hole.

[0051] Specifically, in this embodiment, there are four insertion rods 23, which are distributed in a cross shape on the first transmission assembly 22, which can further improve the stability of the device. In other embodiments, the number of insertion rods 23 can be set as needed. In addition, in this embodiment, the two ends of the fixing seat 1 are respectively provided with extension plates, and the fixing structure 2 is arranged on the extension plates.

[0052] Furthermore, if Figure 2 and Figure 3 As shown, the first transmission assembly 22 includes a rotating shaft 221, a rotating block 222, a first limiting seat 223 and a plurality of connecting rods 224. The rotating shaft 221 extends vertically and is rotatably connected to the output end of the first driving member 21, the rotating block 222 is connected to one end of the rotating shaft 221 away from the first driving member 21, and the two ends of the connecting rod 224 are rotatably connected to the rotating block 222 and the insertion rod 23 respectively. A guide portion 231 is provided on each insertion rod 23, and the first limiting seat 223 is provided with a plurality of first guide grooves 225 along the circumferential direction, and the plurality of guide portions 231 are slidably provided in the plurality of first guide grooves 225 in a one-to-one corresponding manner. Driven by the first driving member 21, the rotating shaft 221 rotates, thereby driving the rotating block 222 to rotate. Since the two ends of the connecting rod 224 are rotatably connected to the rotating block 222 and the plug rod 23, combined with the sliding cooperation of the guide portion 231 and the first guide groove 225, multiple plug rods 23 can be driven to slide linearly along the first guide groove 225 at the same time, so that multiple plug rods 23 can be inserted or pulled out of the soil layer around the side wall of the fixed hole at the same time. The operation is simple and convenient, saving time and effort. When the device needs to be retracted, the multiple plug rods 23 can be quickly retracted under the drive of the first driving member 21 and the transmission of the first transmission assembly 22.

[0053] For example, in this embodiment, the connecting rod 224 is an L-shaped rod. In other embodiments, the connecting rod 224 may also be a straight rod or an arc-shaped rod. In addition, the first limit seat 223 is circular, and the plurality of first guide grooves 225 extend along the radial direction of the first limit seat 223. In other embodiments, the first limit seat 223 may also be rectangular.

[0054] Optionally, refer to Figure 2 The fixing structure 2 further includes an inserting tube 24, which extends vertically and is arranged on the bottom side of the fixing seat 1. The first transmission assembly 22 and a plurality of inserting rods 23 are arranged in the inserting tube 24. A plurality of slots 241 are provided along the circumferential direction on the side wall of the inserting tube 24. The slots 241 are used to allow the inserting rods 23 to pass through, so as to ensure that the inserting rods 23 are smoothly inserted into the soil layer around the fixing hole. The above arrangement can prevent the soil debris in the fixing hole from falling onto the surface of the first transmission assembly 22 and hindering the transmission of the first transmission assembly 22. At the same time, it has a certain protective effect on each component.

[0055] Optionally, a tip is protruded from one end of the insertion rod 23 facing outwards to facilitate insertion of the insertion rod 23 into the soil layer.

[0056] Optionally, refer to Figure 4 The clamping structure 3 includes a second driving member 31, a second transmission assembly 32 and a plurality of clamping members 33. The second driving member 31 is fixed on the fixed seat 1, and the output end of the second driving member 31 is connected to the plurality of clamping members 33 through the second transmission assembly 32. The plurality of clamping members 33 are slidably arranged on the second transmission assembly 32. Driven by the second driving member 31, the plurality of clamping members 33 can approach or move away from the periphery of the pile driver to clamp or detach from the periphery of the pile driver. The above arrangement enables the device to be applicable to pile drivers of different sizes and has good applicability.

[0057] Exemplarily, the second driving member 31 is a motor commonly used in the art, and the output end of the second driving member 31 can rotate clockwise or counterclockwise to drive the plurality of clamping members 33 to approach or move away from the periphery of the pile driver at the same time.

[0058] Further, continue to refer to Figure 4The second transmission assembly 32 includes a first gear 321 and a second gear 322 that mesh with each other. The first gear 321 is connected to the output end of the second driving member 31, and the second gear 322 is stacked on a plurality of clamping members 33. A slider 331 is convexly provided on the side of each clamping member 33 facing the second gear 322. The second gear 322 is provided with a plurality of slide grooves 323 along the circumferential direction, and the plurality of sliders 331 are slidably provided in the slide grooves 323 in a one-to-one correspondence. Under the drive of the second driving member 31, the first gear 321 rotates, driving the second gear 322 to rotate. Combined with the sliding cooperation between the slider 331 and the slide groove 323, the plurality of clamping members 33 can be driven to slide to approach or move away from the outer periphery of the pile driver. In addition, the number of teeth of the first gear 321 is less than the number of teeth of the second gear 322, which saves space while achieving deceleration and increasing the transmitted torque, and providing a larger torque to ensure the stable sliding of the plurality of clamping members 33. The second gear 322 is provided with an escape hole 324 for allowing a pile driver to pass through. The pile driver passes through the through hole 10 on the fixing base 1 and the escape hole 324 on the second gear 322 in sequence, and is clamped and fixed by the clamping action of the plurality of clamping members 33 .

[0059] Illustratively, in this embodiment, the slide groove 323 is an arc-shaped groove.

[0060] Furthermore, the second transmission assembly 32 further includes a second limit seat 325 protruding from the fixing seat 1, and the second limit seat 325 is arranged around the outer side of the through hole 10. The second limit seat 325 is provided with a plurality of second guide grooves 326 along the circumferential direction, and the second guide grooves 326 extend along the radial direction of the through hole 10. The plurality of clamping members 33 are slidably arranged in the plurality of second guide grooves 326 in a one-to-one correspondence, and under the guiding action of the second guide grooves 326, the clamping members 33 slide along the radial direction of the through hole 10, thereby improving the stability of the clamping members 33 clamping the pile driver.

[0061] For example, in this embodiment, the second limit seat 325 is annular, and a total of eight second guide grooves 326 are provided on the second limit seat 325. Accordingly, a total of eight clamping members 33 are also provided. In other embodiments, the number of second guide grooves 326 and clamping members 33 can be set as required.

[0062] Alternatively, if Figure 1 As shown, the fixing seat 1 includes a first fixing plate 11 and a second fixing plate 12 arranged at intervals in the vertical direction, and a plurality of support columns 13 are arranged between the first fixing plate 11 and the second fixing plate 12. Through holes 10 are provided on the first fixing plate 11 and the second fixing plate 12, a plurality of fixing structures 2 are arranged at intervals on the first fixing plate 11, and a clamping structure 3 is arranged on the second fixing plate 12. The above arrangement enables the clamping structure 3 to be clamped in the middle position of the pile driver, and the stability is higher.

[0063] Furthermore, a plurality of fasteners 14 are provided on the first fixing plate 11 , and the fasteners 14 are used to be inserted into the soil layer around the pile hole to further enhance the stability of the device fixed on the ground.

[0064] Illustratively, in this embodiment, four fasteners 14 are provided on the first fixing plate 11 , and the fasteners 14 may be ground bolts commonly used in the art.
