Abstract

The present invention relates to a pile driver capable of performing hitting by using elastic force, and more specifically, to a pile driver comprising: a housing (100); an operation unit (200) receiving rotary power of an operation means (500) to be rotated inside the housing (100); and a hitting unit (300) to perform hitting by operation of the operation unit (200) on one side of the housing (100). The operation unit (200) comprises: an operation shaft (210) installed inside the housing (100) and having a first gear (211) on an outer circumference; a second gear (220) engaged with the first gear (211) to be rotated; and a cam (230) formed on one side of the second gear (220). The hitting unit (300) comprises: a hitting assembly (310) installed inside the housing (100) and periodically being in contact with the cam (230) to perform reciprocal motion; and an elastic member (320) installed between an upper part of the hitting assembly (310) and an inner upper side of the housing (100) to move the hitting assembly (310) in operation of the operation unit. Thus, the pile driver is formed in a simple structure. Since a hit is continuously and periodically applied while the pile driver is used by connecting to an apparatus, such as an existing brush cutter, including an operation means, work convenience is provided. Since hitting is performed through elastic force of the elastic member, not direct friction with the operation means, when a pile or an object is hit, vibration or impact generated in hitting is not transferred to a worker or the operation means, so the pile driver is prevented from being damaged.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pile driver capable of using an elastic force,

The present invention relates to a hinge capable of being struck using an elastic force, and more particularly, to a hinge capable of striking a striking portion that directly applies a striking force to a pile, The present invention relates to a hammering device capable of being hit by using a hammering device.

Generally, many piles are required for cultivation of crops in fields such as construction, civil engineering, and cultivated areas such as red pepper and orchards. To this end, the pile is placed at a desired position and then the operator uses a separate hitting means such as a hammer or hammer have.

In the conventional method, when the work is performed by a worker, it is difficult to accurately hit the pile, and a large force can not be applied at a time, and the upper part of the pile is struck several times, .

In recent years, a hammer is mounted on a machine equipped with a driving means, and a pile hanger hitting a pile is used to easily work.

A main body part having a rotary member rotated by receiving a rotational driving force outside the registration number 20-0469700 (room); A first hitting portion coupled to one side of the body portion and having a hollow housing having a first inner diameter and a hammer periodically reciprocating in a linear reciprocating motion with the rotary member and repeatedly striking an end of the pile; A hollow housing coupled to the other side of the main body and having a second inner diameter larger than the first inner diameter so as to strike an end of the pile having a wider sectional area due to the impact of the first striking part; A second striking part having a hammer which repetitively strikes an end of a pile having a larger cross-sectional area while linearly reciprocating in contact with the striking part; And a rotation connecting member connecting the main body and the cable for transmitting a rotational driving force to the rotating member and rotatably coupled to the main body.

No. 10-0932662 (Actual) An air knocker connected to a compressor to extrude air at a high pressure; A cylinder coupled to a lower portion of the air knocker and having an air communication hole formed therebetween so as to be penetrated into the air communication hole by being elastically supported by an elastic body; And a pile support portion coupled to a lower portion of the cylinder, the pile support portion having a hollow formed therein so that a pile can be inserted therein, a through hole formed at an upper end thereof to penetrate and insert the hammer, Wherein the hammer is divided into a first stage jaw and a second stage jaw with a boundary between the first and second stages, and the first and second stage jaws are provided with an elastic spring And a gripping flange is provided on a connection portion between the cylinder and the pile support portion and a striking plate is provided on the inner diameter of the pile support portion so as to have a cap shape and the handle is extended to the lower direction of the pile support portion And an elastic spring for buffering an impact is provided at a joint portion with the pile support portion.

The prior art described above uses a hammer drill to place a pile on the bottom of the holder and directly strike the top of the holder. However, this technique is practically applied to the case where the force It is difficult to concentrate and it is necessary to blow several times, so that the device is overloaded and the work time is long.

In another type of technology, the first and second striking parts are operated by direct friction due to the rotation of the rotating member by receiving an external rotational driving force while the operator grips and fixes the striker. Frequent abrasion and impact due to friction are exerted by the external rotational driving force in addition to the rotating member and also applied to the worker, so that there is a problem that the device is damaged and inconvenience of the work is accompanied.

Another type of technology is a pile hanger which can easily and firmly pile the pile on the ground by using high-pressure air. The structure is very complicated, so that the manufacturing cost is high and the air supply means must always be provided. Therefore, when the pile is continuously hit, the hammer moved downward by the air supply is restored to its original state by a predetermined pressure or magnet remaining in the interior. As a result, It is necessary to carry out the operation of the first hammer and the flowable clearance of the first hammer must recognize the state before the pile striking as the entirety of the worker so that the hitting force is inevitably lowered when the worker is not a skilled worker .
