[0021] The embodiment of the present application provides a piling device with adjustable piling force, which effectively solves the problem that the existing piling device is unable to adjust the force during piling according to the hardness of the soil and is unable to adjust the force when piling piles of different sizes, thereby reducing the efficiency of piling and increasing the risk of damage to the pile body. The present invention provides a fixing plate and a locking screw at the upper end of the impact block, so that when the device impacts the pile rod, a weight block can be added and then threadedly connected to the fixing plate by the locking screw to fix the weight block, thereby increasing the weight of the impact block. When the gravity of the impact block increases, due to the relationship between the weight and the falling acceleration, the function of adjusting the piling force is achieved, and the device can also adjust the force by adjusting the falling height of the impact block.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing piling device cannot adjust the force during piling according to the soil hardness, cannot adjust the force when piling piles of different sizes, thereby reducing the efficiency of piling and increasing the risk of pile damage. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a pile driving device with adjustable pile driving force, including a guide cylinder 11, a U-shaped frame 21 is provided on the guide cylinder 11, a base bracket 27 is fixedly installed at the lower end of the U-shaped frame 21, rectangular holes 22 are penetrated on both sides of the U-shaped frame 21, and fixed screws 25 are fixedly installed in the two rectangular holes 22 opened in the U-shaped frame 21, a threaded sleeve 24 is penetrated and installed on the circumferential surface of the fixed screw 25 through a thread, a semicircular positioning ring 23 is penetrated and sleeved on the circumferential surface of the threaded sleeve 24, a pile rod 29 is provided between the two semicircular positioning rings 23, an impact block 12 is slidably installed in the guide cylinder 11, a cylindrical rod 16 is fixedly installed on the upper end of the impact block 12, a weighting block 13 is sleeved on the surface of the cylindrical rod 16, and a fixing plate 15 is fixedly installed on the upper end of the cylindrical rod 16 When the device uses the pile rod 29 to drive piles into the ground, the pile rod 29 is inserted from the upper end of the guide cylinder 11, and then passes through the two semicircular positioning rings 23, and then is flush with the ground, and then the threaded sleeve 24 can be rotated. Through the threaded connection between the threaded sleeve 24 and the fixed screw 25, the threaded sleeve 24 can be moved up, and the semicircular positioning ring 23 can be driven to move up while the threaded sleeve 24 moves up, so that the two semicircular positioning rings 23 support the middle section of the pile rod 29 to prevent the pile rod 29 from deflecting when being hammered. After that, the user can reel in the steel cable 17 through the winch 26, and then release it, and impact the pile rod 29 through the gravity of the impact block 12 itself and the falling acceleration, and then reel in the steel cable 17 through the winch 26 and then release it, thereby completing the piling process.

[0025] The fixing plate 15 is provided with a locking screw 14 through a thread, and the semicircular positioning rings 23 in the two rectangular holes 22 of the U-shaped frame 21 are relatively fitted, and the locking screw 14 is fitted to the upper end of the weight block 13, and the upper end of the cylindrical rod 16 is fixedly provided with a steel cable 17, and the U-shaped frame 21 is fixedly provided with a support rod 28, and the support rod 28 is rotatably provided with a roller 18, and a winch 26 is fixedly provided with a base bracket 27, and the winch 26 is fixedly connected with the steel cable 17, and the steel cable 17 is slidably installed on the surface of the roller 18. The fixing plate 15 and the locking screw 14 are provided at the upper end of the impact block 12, so that the device can impact the pile rod 29. When the weight block 13 is added, it is threadedly connected to the fixing plate 15 by the locking screw 14 to fix the weight block 13, thereby increasing the weight of the impact block 12. When the gravity of the impact block 12 increases, due to the relationship between the weight and the falling acceleration, the function of adjusting the piling force is completed, and the device can also adjust the force by adjusting the falling height of the impact block 12. The two semicircular positioning rings 23 set in the U-shaped frame 21 of the present invention can limit the semicircular positioning rings 23 when piling, and the height of the two semicircular positioning rings 23 can be adjusted, which is very convenient to use.

[0026] Working principle:

[0027] In the first step, when the device uses the pile rod 29 to drive piles into the ground, the pile rod 29 is inserted from the upper end of the guide cylinder 11, and then passed between the two semicircular positioning rings 23, and then flush with the ground, and then the threaded sleeve 24 can be rotated. Through the threaded connection between the threaded sleeve 24 and the fixed screw 25, the threaded sleeve 24 can be moved up, and the semicircular positioning ring 23 will be driven up while the threaded sleeve 24 moves up, so that the two semicircular positioning rings 23 support the middle section of the pile rod 29 to prevent the pile rod 29 from being offset when being hammered. After that, the user can reel in the steel cable 17 through the winch 26, and then release it, and impact the pile rod 29 through the gravity of the impact block 12 itself and the falling acceleration, and then reel in the steel cable 17 through the winch 26 and then release it, thereby completing the piling process.

[0028] In the second step, the present invention provides a fixing plate 15 and a locking screw 14 at the upper end of the impact block 12, so that when the device impacts the pile rod 29, the weight block 13 can be added, and then the locking screw 14 is threadedly connected to the fixing plate 15 to fix the weight block 13, thereby increasing the weight of the impact block 12. When the gravity of the impact block 12 increases, due to the relationship between the weight and the falling acceleration, the function of adjusting the piling force is completed, and the device can also adjust the force by adjusting the falling height of the impact block 12. The present invention provides two semicircular positioning rings 23 in the U-shaped frame 21, so that the semicircular positioning rings 23 are limited when piling, and the height of the two semicircular positioning rings 23 can be adjusted, which is very convenient to use.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
