The present invention is installed on the inside of the hanger that is bound to the wire of the crane, the soft ground reinforcing sheet for pressing or drawing the sheet pile to the predetermined depth to the ground is coupled to the chuck to hold the soft ground reinforcing sheet pile The present invention relates to a pile press-fitting and drawing device, and more particularly, a motor generated when a sheet pile is press-fitted for soft ground reinforcement by operating a piston as a high-pressure air without using a driving motor to prevent mechanical overload. And the overload of machinery, which eliminates the risk of failure in the motor or gear parts and bearings, thereby reducing labor costs, logistics costs, maintenance costs, etc. caused by frequent machine repairs and replacements. The present invention relates to a sheet pile press-fitting and drawing device for reinforcing soft ground.

In general, the driving or driving the seat pile pressed into the ground to strengthen the soft ground is a hanger (1) is bound to the wire of the crane (not shown) as shown in Figure 1 perpendicular to the predetermined position on the ground I'm hanging.

Then, after holding a sheet pile (not shown) in the chuck 2 coupled to the lower end of the driving machine 10, and applying power to the driving machine 10 from the moment when the lower end of the sheet pile is in contact with the ground, The drive motor 3 of the driving machine 10 rotates, and the rotational force is changed into a linear motion to generate vibration in the oscillation unit 4.

Therefore, the conventional anti-taking 10 is composed of the operating principle of the oscillator to generate a vibration by a mechanical configuration, at this time, is pressed into the ground on the sheet pile by the force of the linear motion (vibration) generated.

However, the above-described conventional rider 10 has a rotating shaft (not shown), a driving gear (not shown), and an interlocking gear (not shown) for converting the rotational motion of the driving motor 3 into linear motion as described above. ) And a hammer (not shown), the vibration generated when the sheet pile is press-fitted causes a failure in the coupling structure of the mechanical components.

In addition, even if it is operated for a long time on a solid ground or bad seat pile, overload occurs in these machines, causing frequent failures in the drive motor, gear, bearing, etc., and frequent replacement and repair of parts and delay in working time. You have a problem.

In addition, since the conventional driving machine 10 is used only to press-in the sheet pile, the drawing time of drawing the sheet pile may cause trouble such as the need to cover the adjacent ground around the sheet pile. Of course, this also leads to a huge expense of work costs.

The present invention devised to solve the above problems can be performed to selectively perform the work to press or draw the sheet pile to shorten the working time, so as not to overload even if the hard ground or bad sheet pile is pressed The purpose is to shorten the working time and reduce the maintenance cost by not causing mechanical defects and failures.

As a device for switching so that it may be a three-way opening and closing device that is commonly used, and may be a three-way using a solenoid, the present invention is not limited to this, but the inlet air is drawn in with the air supply pipe 120 for drawing Since it can be selectively branched toward the air supply pipe 121, the detailed description thereof will be omitted below.

In addition, the through hole 115 inserted into the guide 112a of the fixed valve 112 is formed vertically, and is inserted into the wear sleeve, the upper and lower piston 113, respectively, on the upper and lower portions of the fixed valve 112. ) 114 is inserted, a plurality of air indentation grooves 116 are formed on the outer diameter surfaces of the upper and lower pistons 113 and 114 extending to a predetermined length in the up and down directions, The groove 116 is not formed to extend at both ends, but is formed only from the lower predetermined position of the outer diameter surface of the upper and lower pistons 113 and 114 to the upper predetermined position as shown, and the upper and lower pistons 113 and 114. ) Is in communication with the upper and lower hitting parts 106 and 107 in communication with the lower and lower grooves 108 and the elevating grooves 111 formed on the upper and lower inner diameter surfaces of the upper and lower wear sleeves 109 and 110. Or only up to a position that can be in an open state.

In addition, the through hole 115 penetrating to the upper and lower ends of the upper and lower pistons 113 and 114 is inserted into the guide 112a of the fixed valve 112, and the upper and lower striking parts 106 and 107. Exhaust guide pipe 126 of a predetermined height is inserted into the through hole of the upper and lower pistons 113 and 114, respectively, when the upper and lower pistons 113 and 114 are raised and lowered. The through holes 115 are respectively inserted in the lower portion.

Meanwhile, the upper and lower pistons 113 and 114 are inserted to be in close contact with the inner diameters of the upper and lower wear sleeves 109 and 110 and are in contact with upper and lower predetermined portions of the fixed valve 112 and the fixed valve 112. The upper and lower inner sleeves 117 and 118 are enveloped in a predetermined portion of the outlet, and the air supplied to the air flow path 112b of the fixed valve 112 is formed in the upper and lower inner sleeves 117 and 118. It is to be guided to the air inlet groove 116 by (125).

On the other hand, after holding the sheet pile by the chuck 102, when pressurized into the ground, the high-pressure air is supplied to the air hose 124 from a remote air compressor, but the air is pressurized by operating the air switching device 119 It can be supplied to the air supply pipe 121.

Therefore, the air supplied to the air flow path 112b of the fixed valve 112 through the press-fit air supply pipe 121 is supplied to the lower wear sleeve 110 through the distribution hole 125 of the inner sleeve, Since the upper portion of the outer diameter of the lower piston 114 disposed below the fixed valve 112 is in close contact with the inner diameter of the inner sleeve, the air moves immediately along the air inlet groove 116.

Here, the end of the air pressurizing groove 116 is open to the lifting groove 111 of the lower wear sleeve 110, as shown in Figure 2, so that the lower piston 114 of the lifting groove 111 Supplied at the bottom.

At this time, the lower portion of the lower piston 114 is in close contact with the lower striking portion 107 and the through hole 115 of the lower percussion portion and the lower portion of the through hole 115 of the lower piston 114 are simultaneously inserted with the exhaust guide pipe 126. As a result, it has a sealed structure.

Therefore, the air supplied below the lower piston 114 floats (elevates) the lower piston, and when the lower piston 114 which has been elevated by the supplied air reaches a predetermined position, that is, the lower piston 114 The lower end of the air inlet groove 116 of the elevating groove 111 is out of the open state and ascend more than at the same time as shown in Figure 3 the through hole 115 of the lower piston 114 is the exhaust guide pipe ( When the air escapes from 126, the air that raises and lowers the lower piston 114 from the lower piston 114 is discharged through the through hole of the exhaust guide pipe 126 and the lower striking part 107 and the exhaust opening 123 of the lower opening / closing member 105. ) Is exhausted into the space between the casing 103 and the lower wear sleeve 110.

At this time, the air supplied to the distribution hole 125 of the lower inner sleeve 118 is compressed by the air inlet groove 116 to lower the lower piston 114, the lower piston 114 is to lower the lower striking portion 107 The hitting force generated at this time acts on the chuck 102 and the sheet pile held by the chuck 102 to press the sheet pile into the ground.

In addition, as described above, after the lower piston 114 hits the lower striking part 107, the air pressurizing groove 116 and the lifting groove 111 have a state in which they are open to each other, and are continuously supplied. Air is again supplied to the lower portion of the lower piston 114 to elevate the lower piston 114. After the lower piston 114 is elevated to a predetermined height, the air is introduced into the air indentation groove 116 as described above. While the lower piston 114 is forcibly lowered while being supplied, the air remaining in the lower portion of the lower piston 114 repeats the operation of exhausting through the exhaust guide pipe 126 about 600 times per minute.

On the other hand, in order to draw the sheet pile press-fitted into the ground to bind the hanger 101 to the wire of the crane and to allow the sheet pile to be gripped by the chuck 102, the air switching device 119 is supplied to the air supplied To be supplied to the drawing air supply pipe (120).

Therefore, the air supplied to the drawing air supply pipe 120 is guided to the distribution hole 125 of the upper inner sleeve 117 via the air flow path 112b of the fixing valve 112, and the upper inner sleeve 117 The air guided to the distribution hole 125 of the air of the upper piston 113 whose outer diameter is in close contact with the inner diameter of the upper wear sleeve 109 in a state seated on the upper portion of the fixed valve 112 as shown in FIG. The upper piston 113 is supplied to the indentation groove 116 to lift the upper piston 113 to strike the upper striking portion 106.

At this time, when the upper piston 113 strikes the upper striking portion 106, the striking force not only acts on the casing 103 and the hanger 101, but also acts on the chuck 102 coupled to the lower end of the casing 103. It acts as a force for forcing (lifting) the sheet pile pressed into the ground.

Here, when the upper piston 113 hits the upper striking portion 106, the upper end of the air indenting groove 116 of the upper piston 113 is the lower groove 108 formed on the upper inner diameter surface of the upper wear sleeve 109 ) And the air supplied to the air pressurizing groove 116 is supplied between the upper piston 113 and the upper striking part 106 along the lower groove 108 to lower the upper piston 113. In this way, the upper piston 113 is lowered accordingly.

Then, when the upper piston 113 is lowered by a predetermined distance, that is, the upper portion of the through hole 115 of the upper piston 113 exits the exhaust guide pipe 126 and the air inlet groove 116 of the upper piston 113 When reaching the position which is out of the open state with the lower groove 108, the upper piston 113 is raised and lowered again by the high pressure air supplied to the air inlet groove 116, at this time, the upper piston 113 The air remaining at the upper portion of the air is exhausted along the exhaust hole 123 of the upper opening and closing member 104 and the through hole of the exhaust guide pipe 126 and the upper striking portion 106 by the compression of the upper piston 113 to move up and down. .

Therefore, the air inlet groove 116 and the lower groove 108 of the upper piston 113 are reciprocated (rising) up and down while repeating the opening and closing states by the air pressure continuously supplied. This continually occurs, wherein the upper piston 113 hits the upper striking portion 106 about 600 times per minute, so that the sheet pile held by the chuck 102 can be drawn out of the ground.

Here, the upper and lower striking portion 106, 107 is preferably embedded in the dustproof material 122 to cushion the shock and noise as shown in Figure 2 to prevent physical impact and noise. Do.

In addition, when the sheet file is press-fitted due to the work characteristics, only the press-in operation of the plurality of sheet files is continuously performed, and when the sheet file is pulled out, only the plurality of sheet-file drawing operations are continuously performed, so that the air switching device 119 It is also possible to use a manual or remote automatic switching device, the present invention is not limited to this.

As described above, the present invention mechanically converts the rotational motion of the drive motor into a linear motion and oscillates so that the physical force acts on the mechanical component, thereby reducing the conventional problem that the weakening of the coupling force between the mechanical components and defects occur. By supplying the air to make the straight reciprocating movement so that mechanical components are not affected by the physical force, the maintenance cost incurred by frequent breakdowns and parts replacement can be minimized. It is possible to utilize driving during drawing work, which has the effect of drastically shortening the work time required for drawing work of sheet file.
