Description

{Reader module for ground excavators}

The present invention relates to a reader module for a ground excavator coupled with a guide rod for vertically guiding a drive device in a ground excavator. More specifically, the reader module is configured as a square type, The present invention provides a reader module for a ground excavation that enables a reader module to be manufactured at a low cost and to have a long service life.

A ground excavator is a construction machine that drills a ground in a foundation work for a construction structure to form a digging hole.

The basic structure of the ground excavator is such that a leader, which is a vertical shaft type structure, is mounted in front of the self-propelled vehicle body, and a driving device is coupled to the leader.

As a representative example of the above-described leader, a leader structure of a hanger of the Korean Utility Model Registration Utility (Y1) 20-0127795 has been proposed. The structure of the hanger is composed of auger and hammer, Wherein the guide rails are provided on the front and one side surfaces of the adjusting mast of the leader mast in the longitudinal direction, wherein the guide rails are provided on the guide rails of the first adjusting mast, And a guide rail having an insertion groove at an upper end thereof in three directions, and the top end of the leader mast, A plurality of rear surface rollers and front surface rollers selectively guided and guided by the auger wires, Fastening a guide for the direction in which optionally being provided with bilateral switching roller and side rollers, and would work the hayeoseo wire is selectively fastened to consist of guide rollers respectively disposed in both side surfaces.

As another example, a modular reader for a live live of Korean Registered Patent No. B1-12-120094 (Feb. 23, 2013) is proposed, and its configuration is constituted by connecting a plurality of tubular bodies formed with flanges at both ends thereof, And a coupling recess and a coupling protrusion are formed at both ends of the guide rod. When the tubular body is connected, the coupling recess and the coupling protrusion of the guide rod are coupled to each other. When the slider of the driving device is coupled to the guide rod The connection and the diameter of the projecting shaft are formed at both ends of the pipe body having the flange formed therein, and the connecting pipe is formed by partially expanding the inner diameter of the pipe body The diameter of the projecting shaft portion is reduced and the outer diameter of the tube body is reduced. The inner diameter of the connection reamer and the outer diameter of the projecting shaft portion are formed to coincide with each other, And an engagement / withdrawal / engagement portion coupled to the connection extension; An outer peripheral surface of an annular plate, which is an annular plate concentric with the tubular body, is joined and fixed to the inner peripheral surface of the tubular body, and the annular plate is joined in a direction orthogonal to the tubular center line.

However, in the case of the above-described conventional reader, there is a disadvantage that the guide rod is provided only on one side, and the guide rod is replaced by the reader or the entire reader is exchanged when the guide rod is worn.

Accordingly, the present inventor has provided a novel reader module for a ground excavator which can solve the above-mentioned problems of the prior art earthmoving machine readers, thereby remarkably reducing the manufacturing cost while prolonging the service life. will be.

That is, in the case of a guide rod applied to a reader, four guide rods are disposed in a square shape on the assumption that only the outer surface of the guide rod is worn when the reader is fitted to the reader coupling provided in the driving device. A reader module in which the support plate is coupled to the inner space sealed by the side finishing plates at regular intervals and the support plate is exposed by forming a through hole with a predetermined width in the side finishing plate, The present invention provides a new and improved reader module for a ground excavator which can rotate a lead 90 degrees when a guide rod is worn and replace a guide rod after four times of using one reader. Thereby completing the present invention.

According to an embodiment of the present invention, a reader applied to a ground excavator comprises a reader module having a predetermined length; Wherein the reader module comprises: four guide rods disposed at a corner of a square when viewed in a plan view; Side end closure plates welded to both guide rods in the axial direction of the guide rods; And support plates welded to the side finishing plates at regular intervals in the inner space sealed by the side finishing plates at right angles with the guide rods; A through hole formed in the side finishing plate to expose the supporting plate; A handle combined with a foot plate provided on the support plate so as to be exposed through the through hole; And an assembly hole formed on the upper and lower end sides of the guide rod so as not to interfere with the side finishing plate so that the leader module can be disassembled and assembled by the fixing means composed of bolts and nuts.

Second, the footrest combined handle has an inner groove formed in each of four sides of a support plate exposed through a through hole formed in the side finishing plates; And a rod-like gripping rod having both ends thereof connected to the support plate so as to be horizontally disposed with respect to the support plate.

Third, the assembly hole is formed in an externally exposed shape by a work hole formed by cutting a part of the side finishing plate at the upper and lower end sides of the guide rod.

The use of the reader module for a ground excavator provided in the present invention has the following effects.

Since four guide rods are arranged at regular angles, it is possible to reuse four times by turning the guide rods by 90 degrees when they are worn.

A through hole is formed in the side finishing plate and a hole is formed at the center of the support plate, so that the weight of the leader can be minimized.

It is possible to recycle the reader 4 times by replacing -4 guide sticks, which can minimize the cost of manufacturing and repairing the reader.

- It is possible to fulfill the function of ladder with good appearance because it is not exposed to the outside of the side finishing plate by being formed on the supporting plate, which serves as a ladder.

- Leader length can be easily extended by stacking reader modules.
