Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] gas The dynamic pile driver is a mechanized hand tool that uses compressed air as the power source to generate mechanical impact and strike the workpiece object. It is suitable for hammering steel drill piles and other similar piles to the ground on the construction site. It is a building frame and It is an ideal piling tool for electric ground piles and other industries. It can replace traditional manual sledgehammer strikes. It has large striking force, fast striking speed, high efficiency, convenient operation and low labor intensity.

[0022] Concrete structure of the present invention sees figure 1 As shown, it includes a casing 6, a cylinder body 43, a valve cabinet 18, a valve plate 19, a valve cover 36, a coupling sleeve 9, an impact rod 45, and a hammer body 40. The coupling sleeve 9 is placed on the upper end of the...

Abstract

The invention discloses a pneumatic pile driver, and relates to the technical field of a pile driver. The pneumatic pile driver comprises a case, an impacting rod, a hammer body, a sleeve, a cylinder, a valve cabinet, a valve plate, a valve cover and a connecting sleeve, wherein the outer wall of the case is provided with a left support frame and a right support frame with handles, the connecting sleeve is arranged at the upper end in a casing of the case, the valve cabinet, the valve plate and the valve cover are arranged in the connecting sleeve from top to bottom, the upper end of the cylinder body is provided with external screw threads, the lower end of the connecting sleeve is provided with internal screw threads, the cylinder body is connected with the connecting sleeve through screw threads, the upper end surface of the cylinder body is in contact with the lower end surface of the valve cover, the valve cabinet, the valve cover and the cylinder body are in positioning connection through a second cylindrical pin, an air path hole of the valve cabinet, an air hole of the valve cover and a lower air inlet hole of the cylinder body are vertically penetrated, and are communicated with an inner cavity of the cylinder body through a communicating hole formed in the lower end of the cylinder body, the middle part of the cylinder body is provided with an exhaust hole not communicated with the lower air inlet hole, the exhaust hole is communicated with the inner cavity of the cylinder body, and compressed air enters the connecting sleeve via an air connecting pipe through an air path rotating switch arranged on the handles, and is communicated with the air paths of the cylinder body, the valve cabinet, the valve plate and the valve cover. The pneumatic pile driver has the advantages that the airflow is smooth, the driving force is strong, the driving speed is high, and the pile driving efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pile drivers, in particular to a pneumatic pile driver. Background technique [0002] For small-scale piling or pile planting in building construction, the piles to be implanted are generally manually tapped with a sledgehammer to drive the piles into the ground. This construction method is time-consuming, laborious, inefficient, and The piles are easy to deflect, which is easy to cause safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pneumatic pile driver, which is easy to operate, strong in striking force, fast in striking speed and high in piling efficiency. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pneumatic pile driver, including a casing, an impact rod, a hammer body, a casing, a cylinder body, a valve cabinet, a valve plate, a valve ...
