VIBRO-HAMMER HAVING SIDE GRIP
[Technical Field]

[Background Art]
[2] In general, in order to build all structures such as a building or a bridge on the ground, a foundation work must be performed to embed a concrete pile, a steel pipe pile, and an I-beam so that the ground can withstand the weight of the structure.
[3] In the case of the pile construction, the pipe construction is very important in constructing the structure and the building, and in particular, in the case of soft ground, the foundation work in which a pile is drive and fixed in a bedrock in a basement layer below the ground surface should be carried out, and in the foundation work, an operation of driving a pile into the ground is called a driving operation.
[4] Recently, in the driving operation, a method is mainly used, which vibrates a chuck in a driving direction, that is, in a vertical direction with respect to the pile, using a drive gear and an eccentric weight operated by driving a motor in a state where the pile is fixed through the vibro-hammer. Accordingly, a friction between the pile and the ground is reduced through the vibrations of the pile, and thus, a smooth driving operation is achieved.
[5] Meanwhile, since vibrations generated from a gear device including the motor, the drive gear and the eccentric weight are transmitted not only to the pile but also to the connected heavy equipment machine for construction, there is a concern that the machine is overwhelmed and may cause a breakdown.
[6] In addition, when vibrations are transmitted to a heavy equipment machine, there is a concern that a position is deviated from an initial position at which the driving operation is performed, and in this case, the position of the file is also changed together.
Accordingly, there is a fatal disadvantage that the file cannot be stably driven into the ground and the foundation work is poor.

[56] Prior to the description, the perforated pile described in the present disclosure is divided into a sheet pile PI, an I-type file P2, and circular piles P3 and P3' according to the shapes thereof, and when explaining by applying different perforated piles PI, P2, and P3 as necessary, it should be stated that the description is given with reference numerals.
[57] The present disclosure relates to a vibro-hammer connected to heavy construction equipment, and more particularly, a vibro-hammer having a side grip in which vibrations are prevented from being transmitted to a connected heavy equipment machine to avoid a problem such as a change in a perforation position and the vibro-hammer is firmly connected to a perforated pile to transmit vibrations generated in a gear box to the perforated pile through the side grip and improve workability, and the vibro-hammer 1 includes a mount portion 1000, a side clamp portion 2000, a housing bracket 3000, and a bottom clamp 4000.
[58] The mount portion 1000 is connected to a boom bracket or quick coupler installed at a distal end of a boom of a construction heavy equipment machine such as an excavator and shovel.
[59] The mount portion 1000 has a plurality of holes which are formed on an upper surface to be coupled to the heavy equipment machine, and a lower surface of the mount portion 1000 is coupling-fixed in close contact with an upper surface of the housing bracket 3000 in a vertical direction.
[60] The side clamp portion 2000 generates vibrations through a provided gear box module 2110 provided to transmit the vibrations to a connected arm 2300 and a side grip 2400, and plays a role of easily griping and vibrating the perforated pile so as to perform perforation work. This side clamp portion 2000 includes a gear box 2100, a cylinder 2200, the arm 2300 and the side grip 2400.
[61] The gear box 2100 includes the gear box module 2110 therein and has a box frame 2101 in the shape of a hexahedron with opened front surface and rear surface, and inside the box frame 2101, a plurality of horizontal frames 2102 divided into regions along an inner height of the box frame 2101 are provided.
[62] First, a cylinder coupling shaft 23130 coupled to an upper arm 2300a descried later and a pair of rotating shafts 2120 are provided inside the uppermost horizontal frame, and the pair of gear box modules 2110 is provided at a center of the inside of the box frame 2101 having the horizontal frame 2102 as upper and lower surfaces, and thus, generates vibrations.
[63] A hydraulic motor 2111 is provided on a rear surface of the gear box module 2110 to generate vibrations, and as illustrated in FIG. 2A, a gear 2110b and an eccentric weight 2110c are coupled to shaft 2110a inside the gear box module 2110 to generate vibrations.
[64] The vibrations generated by the gear box module 2110 is connected to the box frame 2101 and the horizontal frame 2102, and is transmitted to the arm 2300 and the side grip 2400 connected to the gear box 2100. Accordingly, the perforated pile gripped by the side grip 2400 is vibrated.
[65] A horizontal frame 2102 having a vertical distance corresponding to the heights of the rotating shaft 2120 and the cylinder coupling shaft 2130 is also provided on the lower side where the gear box module 2110 is provided. That is, the inside of the box frame 2101 is divided into three zones, the gear box module 2110 generating vibrations is provided at the center thereof, and on upper side and lower side based on the gear box module 2110, the rotating shaft 2120 and the cylinder coupling shaft 2130 coupled to the cylinder 2200 and the arm 2300 are coupled to the horizontal frame 2102 located in the vertical direction, and thus, the cylinder 2200 and the arm 2300 are not deviated from installation positions thereof, and are connected to the box frame 2101 to receive vibrations.
[66] Moreover, an engagement portion 2140 is provided on a front surface on which the rotating shaft 2102 and the cylinder coupling shaft 2130 so as to prevent the pair of arms 2300 from excessively rotating inward. That is, an engagement groove is formed on the rear surface side of the engagement portion 2140 to be recessed in the front surface direction from the rear surface, and in order to prevent the gear-coupled first and second arms 2310 and 2320 from being separated from each other due to excessive rotation of a gear arm 2330 described later, the first and second arms are gear-coupled inside the engagement groove 2141.
[67] Moreover, a front frame 2103 is provided on the front surface side of the gear box 2100, the arm 2300 is introduced into an inlet/outlet hole 2104 formed to horizontally penetrate the front frame 2103 so as to move the inside of the inlet/outlet hole 2104, and thus, the pair of arms 2300 can be prevented from excessively rotating.
[68] The rotating shaft 2120 vertically penetrates rotating shaft introduction holes 2302 respectively formed in the first and second arms 2310 and 2320, the first and second arms 2310 and 2320 can rotate about the coupled rotating shaft 2120, the cylinder coupling shaft 2130 penetrates the shaft coupling hole 2210 formed on one end of the cylinder 2200 and is coupled thereto, the other end of the cylinder 2200 is coupled to the first arm 2310 formed in the cylinder coupling hole 2301 of the arm 2300 to drive the cylinder 2200, and thus, the first arm 2310 rotates about the rotating shaft 2120.
[69] The cylinder 2200 is driven so that the connected arm 2300, that is, the first arm 2310 rotates about the coupled rotating shaft 2120. When the first arm 2310 is rotated to one side by the driving of the cylinder 2200, the pair of arms 2300 is close to each other, comes into close contact with the outer surface of the perforated pile to grip the perforated pile, or when the first arm 2310 rotates to the other side, the pair of arms 2300 is away from each other to be separated from the outer surface of the perforated pile, and thus, is detached from the perforated pile.
[70] The cylinder 2200 may be driven by a heavy equipment machine connected to the vibro-hammer 1 or a separate operation module (not illustrated in the drawings) provided outside. As illustrated in FIG. 3A and Fig. 3B, the cylinder 2200 is provided on a side opposite to the positions of the upper arm 2300a and the lower arm 2300b.
Therefore, the side clamp portion 2000 is prevented from being bent one side due to that the cylinder 2200 is driven to one side, and the cylinders 2200 are provided to intersect each other. Accordingly, the side clamp portion 2000 uniformly grips the perforated pile and grips the perforated pile with a good balance, and thus, the side clamp portion 2000 also has a good balance and is prevented from being pulled to one side.
[71] The arm 2300 connected to the cylinder 2200 and the rotating shaft 2120 of the gear box 2100 is divided into the upper arm 2300a located above the gear box 2110 and the lower arm 2300b located below the gear box 2110, and thus, the pair of arms 2300 includes the first arm 2310 and the second arm 2320.
[72] First, in each of the upper arm 2300a and the lower arm 2300bb, the first arm 2310 and the second arm 2320, and the cylinder 2200 are provided on sides opposite to each other in the vertical direction, and thus, when the cylinder 2200 is driven, the first arm 2310 and the second arm 2320, and the cylinder 2200 intersect each other in a plan view.
[73] Each of the upper arm 2300a and the lower arm 2300b is coupled to the side grip 2400, and not simply grip only one side of the perforated pile but grips upper and lower portions on the same vertical line to be in stable-close contact with the perforated pile and fixed to the perforated pile.
[74] The first arm 2310 and the second arm 2320 have the same shape as each other, and the first arm 2310 has a cylinder coupling hole 2301 for coupling the cylinder 2200 on an end portion extending to the cylinder 2200 side.
[75] In each of the first arm 2310 and the second arm 2320, the rotating shaft introduction hole 2302 is formed so that the rotating shaft 2120 vertically penetrates and is coupled to the arm, and gear arms 2330 are formed at a position close to the rotating shaft introduction hole 2302 so that the first arm 2310 and the second arm 2320 are gear-coupled to each other.
[76] The gear arm 2330 is provided on a side on which the rotating shaft introduction hole 2302 of each of the first arm 2310 and the second arm 2320 is provided, and teeth of the gear arm 2330 are formed to protrude the side of the other facing arm 2300. Moreover, in order to easily perform replacement later, the gear is not directly formed on the arm 2300, and the gear arm 2330 formed along a side surface according to a degree of the rotation of the arm 2300 is coupled to the gear coupling hole 2303 so that the arm 2300 and the gear arm 2330 can be coupled.
[77] That is, the upper surface of the gear arm 2330 is provided with a protrusion protruding upward according to the position of the gear coupling hole 2303 which can penetrate the inside of the gear coupling hole 2303, the protrusion is introduced into the gear coupling hole 2303, and thus, the gear arm 2330 and the arm 2300 can be coupled to each other. In addition, when a gear portion of the gear arm 2330 is worn due to frequent use, or the like, only the gear arm 2330 can be removed from the arm 2300 and replaced.
[78] The first arm 2310 and the second arm 2320 protrude to the front surface side of the gear box 2100 about the position where the rotating shaft coupling hole 2210 is formed, and the side surfaces of the perforated piles are easily provided inside, and protrude in a lateral direction so that the perforated pile is easily provided therein.
[79] Moreover, a first coupling bracket 2340 which can be coupled to the side grip 2400 is provided on a protruding end portion of each of the first arm 2310 and the second arm 2320. The first coupling bracket 2340 comes into close contact with the .. second coupling bracket 2420 of the side grip 2400 described later, and a separate coupling member such as a bolt penetrates the first coupling bracket 2340 and the second coupling bracket 2420, and thus, the first and second coupling brackets and 2420 are fixed to each other.
[80] Accordingly, the first and second arms 2310 and 2320 are coupled to the rotating shaft 2120 in the gear box 2100, and vibrations generated in the gear box module 2110 can be transmitted to the side grip 2400 side through the arm 2300.
[81] One end of the side grip 2400 is connected to the arm 2300 so that the side grip 2400 receives the vibrations transmitted from the gear box 2100 side, the other end of the side grip 2400 comes into close contact with the perforated pile to be fixed thereto, the vibrations transmitted from the gear box 2100 side is transmitted to the close contacted perforated pile, and thus, the perforated pile can perform perforation work by the vibrations.
[82] The side grip 2400 extends similarly to the arm 2300 of which one end extends, and an end portion side of the side grip 2400 includes a side grip frame 2410 curved .. inward so that the side grip 2400 comes into close contact with the perforated pile provided inside.
[83] One end of the side grip frame 2410 includes the second coupling bracket 2420 to be coupled to the above-described first coupling bracket 2340.
[84] In this case, in the second coupling bracket 2420, the second coupling bracket .. 2420 has a height corresponding to the pair of first coupling brackets 2340 located at the same vertical line so that the upper arm 2300a and the lower arm 2300b are coupled by one side grip 2400 and the pair of first coupling bracket 2340 respectively provided in the upper arm 2300a and the lower arm 2300b and located on the same vertical line are coupled to the single second coupling bracket 2420 (refer to FIGS. 4A
.. and 6A).
[85] The second coupling bracket 2420 allows the upper arm 2300a and the lower arm 2300b to come into close contact with the perforated pile in the same way through the second coupling bracket 2420 even if the upper arm 2300a and the lower arm 2300b are not driven equally due to a slight difference.
[86] The other end of the side grip frame 2410 includes a close-contact portion 2430 which comes into close contact with the outer surface of the perforated pile.
[87] In the close-contact portion 2430, a close-contact surface in close contact with the perforated pile includes a slight protrusion having a pyramid shape to increase a friction force with the outer surface of the perforated pile and secure stable fixing and .. coupling. Moreover, a shape of the protrusion may be configured in an embodiment illustrated in FIGS. 4 and 5 or another embodiment illustrated in FIG. 6 according to the shape of the perforated pile.
[88] A user of the side grip 2400 having the above-described embodiments separate the first and second coupling brackets 2340 and 2420 coupled according to the shape of the perforated pile from each other, and thereafter, couples the second coupling bracket 2420 of the side grip 2400 to be used to the first coupling bracket 2340. Accordingly, the user can use the side grip 2400 matching the perforated piles having various shapes.
[89] First, when the perforation work is performed using the sheet pile P1, as illustrated in FIG. 4a, the close-contact portion 2430 having a columnar shape in which the close-contact portion 2430 is connected to the other end of the side grip frame 2410 is used, and a plurality of protrusion are formed on the close-contact surface of the close-contact portion 2430.
[90] In this case, together with the second coupling bracket 2420, a vertical bracket 2440 which connects the side grip 2400 coupled to the upper arm 2300a and the lower arm 2300b to the side grip 2400 located on the same vertical line may be provided.
[91] The vertical bracket 2400 prevents the side grip 2400 from being inclined downward due to frequent vibrations and load, and the side grips 2400 located on the upper side and lower side at equal intervals can come into close contact with the perforated pile similarly.
[92] In this case, the vertical bracket 2440 may be contracted or expanded due to thermal deformation or the like. When the vertical bracket 2440 is warped, since the position of the side grip 2400 connected to the upper and lower ends is changed, preferably, a plurality of perforation holes are provided in the vertical bracket 2440.
[93] Accordingly, as illustrated in FIG. 4B, in the sheet pile P1 having the above-

[56] Prior to the description, the perforated pile described in the present disclosure is divided into a sheet pile PI, an I-type file P2, and circular piles P3 and P3' according to the shapes thereof, and when explaining by applying different perforated piles PI, P2, and P3 as necessary, it should be stated that the description is given with reference numerals.
[57] The present disclosure relates to a vibro-hammer connected to heavy construction equipment, and more particularly, a vibro-hammer having a side grip in which vibrations are prevented from being transmitted to a connected heavy equipment machine to avoid a problem such as a change in a perforation position and the vibro-hammer is firmly connected to a perforated pile to transmit vibrations generated in a gear box to the perforated pile through the side grip and improve workability, and the vibro-hammer 1 includes a mount portion 1000, a side clamp portion 2000, a housing bracket 3000, and a bottom clamp 4000.
[58] The mount portion 1000 is connected to a boom bracket or quick coupler installed at a distal end of a boom of a construction heavy equipment machine such as an excavator and shovel.
[59] The mount portion 1000 has a plurality of holes which are formed on an upper surface to be coupled to the heavy equipment machine, and a lower surface of the mount portion 1000 is coupling-fixed in close contact with an upper surface of the housing bracket 3000 in a vertical direction.
[60] The side clamp portion 2000 generates vibrations through a provided gear box module 2110 provided to transmit the vibrations to a connected arm 2300 and a side grip 2400, and plays a role of easily griping and vibrating the perforated pile so as to perform perforation work. This side clamp portion 2000 includes a gear box 2100, a cylinder 2200, the arm 2300 and the side grip 2400.
[61] The gear box 2100 includes the gear box module 2110 therein and has a box frame 2101 in the shape of a hexahedron with opened front surface and rear surface, and inside the box frame 2101, a plurality of horizontal frames 2102 divided into regions along an inner height of the box frame 2101 are provided.
[62] First, a cylinder coupling shaft 23130 coupled to an upper arm 2300a descried later and a pair of rotating shafts 2120 are provided inside the uppermost horizontal frame, and the pair of gear box modules 2110 is provided at a center of the inside of the box frame 2101 having the horizontal frame 2102 as upper and lower surfaces, and thus, generates vibrations.
[63] A hydraulic motor 2111 is provided on a rear surface of the gear box module 2110 to generate vibrations, and as illustrated in FIG. 2A, a gear 2110b and an eccentric weight 2110c are coupled to shaft 2110a inside the gear box module 2110 to generate vibrations.
[64] The vibrations generated by the gear box module 2110 is connected to the box frame 2101 and the horizontal frame 2102, and is transmitted to the arm 2300 and the side grip 2400 connected to the gear box 2100. Accordingly, the perforated pile gripped by the side grip 2400 is vibrated.
[65] A horizontal frame 2102 having a vertical distance corresponding to the heights of the rotating shaft 2120 and the cylinder coupling shaft 2130 is also provided on the lower side where the gear box module 2110 is provided. That is, the inside of the box frame 2101 is divided into three zones, the gear box module 2110 generating vibrations is provided at the center thereof, and on upper side and lower side based on the gear box module 2110, the rotating shaft 2120 and the cylinder coupling shaft 2130 coupled to the cylinder 2200 and the arm 2300 are coupled to the horizontal frame 2102 located in the vertical direction, and thus, the cylinder 2200 and the arm 2300 are not deviated from installation positions thereof, and are connected to the box frame 2101 to receive vibrations.
[66] Moreover, an engagement portion 2140 is provided on a front surface on which the rotating shaft 2102 and the cylinder coupling shaft 2130 so as to prevent the pair of arms 2300 from excessively rotating inward. That is, an engagement groove is formed on the rear surface side of the engagement portion 2140 to be recessed in the front surface direction from the rear surface, and in order to prevent the gear-coupled first and second arms 2310 and 2320 from being separated from each other due to excessive rotation of a gear arm 2330 described later, the first and second arms are gear-coupled inside the engagement groove 2141.
[67] Moreover, a front frame 2103 is provided on the front surface side of the gear box 2100, the arm 2300 is introduced into an inlet/outlet hole 2104 formed to horizontally penetrate the front frame 2103 so as to move the inside of the inlet/outlet hole 2104, and thus, the pair of arms 2300 can be prevented from excessively rotating.
[68] The rotating shaft 2120 vertically penetrates rotating shaft introduction holes 2302 respectively formed in the first and second arms 2310 and 2320, the first and second arms 2310 and 2320 can rotate about the coupled rotating shaft 2120, the cylinder coupling shaft 2130 penetrates the shaft coupling hole 2210 formed on one end of the cylinder 2200 and is coupled thereto, the other end of the cylinder 2200 is coupled to the first arm 2310 formed in the cylinder coupling hole 2301 of the arm 2300 to drive the cylinder 2200, and thus, the first arm 2310 rotates about the rotating shaft 2120.
[69] The cylinder 2200 is driven so that the connected arm 2300, that is, the first arm 2310 rotates about the coupled rotating shaft 2120. When the first arm 2310 is rotated to one side by the driving of the cylinder 2200, the pair of arms 2300 is close to each other, comes into close contact with the outer surface of the perforated pile to grip the perforated pile, or when the first arm 2310 rotates to the other side, the pair of arms 2300 is away from each other to be separated from the outer surface of the perforated pile, and thus, is detached from the perforated pile.
[70] The cylinder 2200 may be driven by a heavy equipment machine connected to the vibro-hammer 1 or a separate operation module (not illustrated in the drawings) provided outside. As illustrated in FIG. 3A and Fig. 3B, the cylinder 2200 is provided on a side opposite to the positions of the upper arm 2300a and the lower arm 2300b.
Therefore, the side clamp portion 2000 is prevented from being bent one side due to that the cylinder 2200 is driven to one side, and the cylinders 2200 are provided to intersect each other. Accordingly, the side clamp portion 2000 uniformly grips the perforated pile and grips the perforated pile with a good balance, and thus, the side clamp portion 2000 also has a good balance and is prevented from being pulled to one side.
[71] The arm 2300 connected to the cylinder 2200 and the rotating shaft 2120 of the gear box 2100 is divided into the upper arm 2300a located above the gear box 2110 and the lower arm 2300b located below the gear box 2110, and thus, the pair of arms 2300 includes the first arm 2310 and the second arm 2320.
[72] First, in each of the upper arm 2300a and the lower arm 2300bb, the first arm 2310 and the second arm 2320, and the cylinder 2200 are provided on sides opposite to each other in the vertical direction, and thus, when the cylinder 2200 is driven, the first arm 2310 and the second arm 2320, and the cylinder 2200 intersect each other in a plan view.
[73] Each of the upper arm 2300a and the lower arm 2300b is coupled to the side grip 2400, and not simply grip only one side of the perforated pile but grips upper and lower portions on the same vertical line to be in stable-close contact with the perforated pile and fixed to the perforated pile.
[74] The first arm 2310 and the second arm 2320 have the same shape as each other, and the first arm 2310 has a cylinder coupling hole 2301 for coupling the cylinder 2200 on an end portion extending to the cylinder 2200 side.
[75] In each of the first arm 2310 and the second arm 2320, the rotating shaft introduction hole 2302 is formed so that the rotating shaft 2120 vertically penetrates and is coupled to the arm, and gear arms 2330 are formed at a position close to the rotating shaft introduction hole 2302 so that the first arm 2310 and the second arm 2320 are gear-coupled to each other.
[76] The gear arm 2330 is provided on a side on which the rotating shaft introduction hole 2302 of each of the first arm 2310 and the second arm 2320 is provided, and teeth of the gear arm 2330 are formed to protrude the side of the other facing arm 2300. Moreover, in order to easily perform replacement later, the gear is not directly formed on the arm 2300, and the gear arm 2330 formed along a side surface according to a degree of the rotation of the arm 2300 is coupled to the gear coupling hole 2303 so that the arm 2300 and the gear arm 2330 can be coupled.
[77] That is, the upper surface of the gear arm 2330 is provided with a protrusion protruding upward according to the position of the gear coupling hole 2303 which can penetrate the inside of the gear coupling hole 2303, the protrusion is introduced into the gear coupling hole 2303, and thus, the gear arm 2330 and the arm 2300 can be coupled to each other. In addition, when a gear portion of the gear arm 2330 is worn due to frequent use, or the like, only the gear arm 2330 can be removed from the arm 2300 and replaced.
[78] The first arm 2310 and the second arm 2320 protrude to the front surface side of the gear box 2100 about the position where the rotating shaft coupling hole 2210 is formed, and the side surfaces of the perforated piles are easily provided inside, and protrude in a lateral direction so that the perforated pile is easily provided therein.
[79] Moreover, a first coupling bracket 2340 which can be coupled to the side grip 2400 is provided on a protruding end portion of each of the first arm 2310 and the second arm 2320. The first coupling bracket 2340 comes into close contact with the .. second coupling bracket 2420 of the side grip 2400 described later, and a separate coupling member such as a bolt penetrates the first coupling bracket 2340 and the second coupling bracket 2420, and thus, the first and second coupling brackets and 2420 are fixed to each other.
[80] Accordingly, the first and second arms 2310 and 2320 are coupled to the rotating shaft 2120 in the gear box 2100, and vibrations generated in the gear box module 2110 can be transmitted to the side grip 2400 side through the arm 2300.
[81] One end of the side grip 2400 is connected to the arm 2300 so that the side grip 2400 receives the vibrations transmitted from the gear box 2100 side, the other end of the side grip 2400 comes into close contact with the perforated pile to be fixed thereto, the vibrations transmitted from the gear box 2100 side is transmitted to the close contacted perforated pile, and thus, the perforated pile can perform perforation work by the vibrations.
[82] The side grip 2400 extends similarly to the arm 2300 of which one end extends, and an end portion side of the side grip 2400 includes a side grip frame 2410 curved .. inward so that the side grip 2400 comes into close contact with the perforated pile provided inside.
[83] One end of the side grip frame 2410 includes the second coupling bracket 2420 to be coupled to the above-described first coupling bracket 2340.
[84] In this case, in the second coupling bracket 2420, the second coupling bracket .. 2420 has a height corresponding to the pair of first coupling brackets 2340 located at the same vertical line so that the upper arm 2300a and the lower arm 2300b are coupled by one side grip 2400 and the pair of first coupling bracket 2340 respectively provided in the upper arm 2300a and the lower arm 2300b and located on the same vertical line are coupled to the single second coupling bracket 2420 (refer to FIGS. 4A
.. and 6A).
[85] The second coupling bracket 2420 allows the upper arm 2300a and the lower arm 2300b to come into close contact with the perforated pile in the same way through the second coupling bracket 2420 even if the upper arm 2300a and the lower arm 2300b are not driven equally due to a slight difference.
[86] The other end of the side grip frame 2410 includes a close-contact portion 2430 which comes into close contact with the outer surface of the perforated pile.
[87] In the close-contact portion 2430, a close-contact surface in close contact with the perforated pile includes a slight protrusion having a pyramid shape to increase a friction force with the outer surface of the perforated pile and secure stable fixing and .. coupling. Moreover, a shape of the protrusion may be configured in an embodiment illustrated in FIGS. 4 and 5 or another embodiment illustrated in FIG. 6 according to the shape of the perforated pile.
[88] A user of the side grip 2400 having the above-described embodiments separate the first and second coupling brackets 2340 and 2420 coupled according to the shape of the perforated pile from each other, and thereafter, couples the second coupling bracket 2420 of the side grip 2400 to be used to the first coupling bracket 2340. Accordingly, the user can use the side grip 2400 matching the perforated piles having various shapes.
[89] First, when the perforation work is performed using the sheet pile P1, as illustrated in FIG. 4a, the close-contact portion 2430 having a columnar shape in which the close-contact portion 2430 is connected to the other end of the side grip frame 2410 is used, and a plurality of protrusion are formed on the close-contact surface of the close-contact portion 2430.
[90] In this case, together with the second coupling bracket 2420, a vertical bracket 2440 which connects the side grip 2400 coupled to the upper arm 2300a and the lower arm 2300b to the side grip 2400 located on the same vertical line may be provided.
[91] The vertical bracket 2400 prevents the side grip 2400 from being inclined downward due to frequent vibrations and load, and the side grips 2400 located on the upper side and lower side at equal intervals can come into close contact with the perforated pile similarly.
[92] In this case, the vertical bracket 2440 may be contracted or expanded due to thermal deformation or the like. When the vertical bracket 2440 is warped, since the position of the side grip 2400 connected to the upper and lower ends is changed, preferably, a plurality of perforation holes are provided in the vertical bracket 2440.
[93] Accordingly, as illustrated in FIG. 4B, in the sheet pile P1 having the above-
17 described configuration, the close-contact portion 2430 comes into close contact with the inside of the sheet pile P1, both end portions of the sheet pile P1 protruding to one side are provided between the arm 2300 extending outward and the side grip 2400, and thus, the close fixing of the perforated pile can be realized.
[94] Thereafter, when the cylinder 2200 is driven and contracted, the first arm 2310 coupled to the cylinder 2200 rotates about the rotating shaft 2120, the gear arm 2330 coupled to the first arm 2310 and the gear arm 2330 of the gear-coupled second arm 2320 rotate in directions opposite to each other, and thus, the second arm 2320 and the first arm are away from each other, the side grips 2400 which are connected to the first and second arms 2310 and 2320 and located at the same horizontal line are away from each other, the close-contact portion 2430 and the perforated pile are away from each other, and thus, the perforated pile and the side grip 2400 can be separated from each other.
[95] Meanwhile, when the I beam (P2) other than the sheet pile P1 and the side grips 2400 are coupled to each other, an auxiliary close-contact portion 2450 which locks the end portions protruding to the side surface of the I beam P2 to the side grip 2400 so as to further fix the I beam P2 may be formed.
[96] The auxiliary close-contact portion 2450 is provided on a front surface side of the side grip 2400 to protrude to the close-contact portion 2430 side, and has a close-contact groove 2451 which is recessed in a direction opposite to the close-contact surface of the close-contact portion 2430.
[97] When the side grip 2400 comes into close contact with the I beam P2, the end portion protruding inside the close-contact groove 2451 can be introduced, and thus, as illustrated in FIG. 5A, the end portion of the I beam P2 can be locked to the inner surface of the close-contact groove 2451 in the auxiliary close-contact portion 2450 to
[94] Thereafter, when the cylinder 2200 is driven and contracted, the first arm 2310 coupled to the cylinder 2200 rotates about the rotating shaft 2120, the gear arm 2330 coupled to the first arm 2310 and the gear arm 2330 of the gear-coupled second arm 2320 rotate in directions opposite to each other, and thus, the second arm 2320 and the first arm are away from each other, the side grips 2400 which are connected to the first and second arms 2310 and 2320 and located at the same horizontal line are away from each other, the close-contact portion 2430 and the perforated pile are away from each other, and thus, the perforated pile and the side grip 2400 can be separated from each other.
[95] Meanwhile, when the I beam (P2) other than the sheet pile P1 and the side grips 2400 are coupled to each other, an auxiliary close-contact portion 2450 which locks the end portions protruding to the side surface of the I beam P2 to the side grip 2400 so as to further fix the I beam P2 may be formed.
[96] The auxiliary close-contact portion 2450 is provided on a front surface side of the side grip 2400 to protrude to the close-contact portion 2430 side, and has a close-contact groove 2451 which is recessed in a direction opposite to the close-contact surface of the close-contact portion 2430.
[97] When the side grip 2400 comes into close contact with the I beam P2, the end portion protruding inside the close-contact groove 2451 can be introduced, and thus, as illustrated in FIG. 5A, the end portion of the I beam P2 can be locked to the inner surface of the close-contact groove 2451 in the auxiliary close-contact portion 2450 to
18 be fixed thereto.
[98] Accordingly, the auxiliary close-contact portion 2450 can fix the side grip 2400 together with the close-contact portion 2430, and even when the I beam P2 is deviated from the side grip 2400 due to excessive vibrations, the I beam P2 is locked to the inside of the close-contact groove 2451, and thus, the I-beam P2 does not move or deviate over a predetermined radius.
[99] Meanwhile, When the outer surface is curved such as the circular pile P3, it is difficult to fix the circular pile P3 to the side grip 2400 in a close contact state by only the pair of close-contact portions 2430. Particularly, when strong vibrations are applied, the side grip 2400 slides along the curved outer surface of the circular pile P3, and thus, there is a concern that the circular pile P3 is deviated from the inside of the side grip 2400.
[100] Accordingly, in another embodiment of the side grip 2400, the pair of close-contact portions 2430 is provided, and the side grip 2400 can be rotated along the .. curvature of the outer surface of the circular pile P3, which will be described with reference to FIGS. 6 to 6C.
