Piling head for pile driver

Abstract

The invention discloses a novel piling head for a piling machine. The novel piling head comprises an impact piece in an impact piece guide sleeve, the outer wall of the lower end of the impact piece guide sleeve is connected with a back pile sleeve covering the upper end of a timber pile in a screwed mode, the internal diameter of the back pile sleeve is larger than that of the impact piece guide sleeve, the inner wall of the lower end of the back pile sleeve is connected with a pile cover sleeve in a screwed mode, the top of the pile cover sleeve is provided with a base plate, the diameter of the base plate is larger than the internal diameter of the pile cover sleeve but smaller than the internal diameter of the back pile sleeve, and a spring is arranged between the bottom of the back pile sleeve and the upper surface of the base plate. According to the novel piling head for the piling machine, the piling acting force is more balanced, the novel piling head can be suitable for piling small piles and can be more suitable for piling large piles, and the piling machine is more stable and more efficient.

Description

technical field [0001] The invention relates to a pile driver head for a pile driver. Background technique [0002] Existing pile drivers are all large-scale machinery with heavy volume, inconvenient operation and transportation, and are not suitable for piling operations of piles such as fence piles in farms and manors. Manual hammering is time-consuming and laborious. In view of the above technical problems, the inventor applied for a "New Pile Driver" (application number: 201420043985.1) on January 24, 2014. This new pile driver is small in size, easy to operate and transport, and can Locate and support the wooden pile, and prevent the broken wooden stick from the upper end of the wooden pile from flying out, eliminating potential safety hazards. [0003] Yet this novel pile driver can only satisfy the piling of small-diameter piles (diameter below 70 millimeters of piles), and its principle is that the impactor 5 of the pile driver directly knocks the piles (referring t...

Problems solved by technology

[0003] Yet this novel pile driver can only satisfy the piling of small-diameter piles (diameter below 70 millimeters of piles), and its principle is that the impactor 5 of the pile driver directly knocks the piles (referring to its instruction manual attached). figure 1 )

Due to the small size of the impactor, the force on the pile is too concentrated during work, which affects the stability and efficiency of pile driving, and it is not suitable for pile driving of large diameter piles (wood piles with a diameter of more than 70 mm and less than 150 mm).
