Description

  The present invention relates to a tubing device for press-fitting and extracting a cylindrical body from the ground, such as casings and steel pipe piles used for foundation work such as construction and civil engineering, and in particular, the work can be performed by approaching a narrow corner portion. The present invention relates to a tubing device with a reaction force weight provided with a reaction force weight that can be made.

  In foundation work such as construction and civil engineering, for example, the casing is pushed into the ground while excavating the earth and sand, the old foundation and other obstacles are removed, the earth and sand in the casing are discharged, and concrete is placed in the inside. There are the all-casing method and the steel pipe pile rotary burying method in which the steel pipe pile is driven into the foundation pile. In such a construction method, a tubing device that rotationally presses a casing and a steel pipe pile into the ground is used. FIG. 10 is a cross-sectional view showing a conventional tubing device.

  In this tubing device 100, four thrust jacks 110, 110... Are erected on a base frame 101, and a lifting frame 102 and a chuck frame 103 are supported on the thrust jacks. In the thrust jack 110, a lift guide cylinder 112 is slidably fitted to a post 111 fixed to the base frame 101, and a chuck guide cylinder 113 is slidably fitted to the lift guide cylinder 112. A thrust cylinder 114 is connected to the inside, and when the thrust cylinder 114 expands and contracts, the lifting frame 102 fixed to the lifting guide cylinder 112 moves up and down.

  The chuck frame 103 is connected to the lifting frame 102 by a chuck cylinder 120 and moves up and down simultaneously with the lifting frame 102 by expansion and contraction of the thrust jack 110. The expansion and contraction of the chuck cylinder 120 moves the chuck frame 103 up and down relative to the lifting frame 102, and the wedge-shaped chuck 121 is inserted between the casing 1 and the cone 122. Therefore, the casing 1 held by the chuck 121 is rotated by the rotation output of the motor 123 transmitted to the cone 122. Therefore, rotation by the motor 123 and contraction operation of the thrust jack 110 are performed simultaneously, and the gripped casing 1 is rotationally press-fitted into the ground.

  When the casing 1 is rotationally press-fitted into the ground, a rotational reaction force and an indentation reaction force act on the tubing device 100, and thus a reaction force removing device is required to reliably rotate and press-fit the casing 1 while suppressing these. The rotary press-fitting is performed by holding the casing 1 with the thrust cylinder 114 extended and sending pressure oil to the contraction side of the thrust cylinder 114 while rotating the casing 1. The pushing force is adjusted according to the condition of the ground so that the pressure is changed and suitable for construction on the ground. However, this pushing force can only be increased up to the weight below the base frame portion. This is because if the pushing force is further increased, the lower part is supported by the casing 1 and floats.

  Therefore, if further pressing force is required, a weight base is coupled to the side surface of the base frame (often on both the left and right sides to prevent an unbalanced load) as a pressing reaction force removal device, and a weight is mounted on the weight base. Thus, in addition to the lower weight, the pushing force is increased to the weight of the weight base and the weight. As for the rotational reaction force removing device, it is common to connect a beam or the like to a base frame and fix it separately with a spike or a working machine. Here, FIG. 11 is a plan view showing a tubing device provided with the reaction force removing device, and FIG. 12 is a side sectional view of the tubing device equipped with the reaction force removing device.

In the tubing device 100, a connecting block 131 is fastened to the side surface of the base frame 101 with bolts. A bracket 132 protrudes from the connection block 131, and a square ring-shaped weight base 133 is pivotally attached thereto. The weight table 133 protrudes horizontally with the connection block 131 and the end surfaces being abutted against each other, and the weight 135 is placed thereon. Further, a beam 136 is connected to the tubing device 100. That is, the connection block 137 is fastened to the side surface of the base frame 101 by bolts and is pivotally attached to the bracket, and the opposite side is fixed by a spike or working machine (not shown).

  By the way, when a building is rebuilt by redevelopment of an urban area, there are already buildings around and the construction site may be partitioned by walls or the like. Therefore, as shown in FIG. 11, the position where the casing 1 is rotationally pressed may be a corner portion formed by the walls K1 and K2. Furthermore, in order to cut an obstacle such as an old foundation with a cutter bit attached to the tip of the casing, a pressing force may be considerably required, and it is necessary to mount a weight as described above. However, in the conventional tubing device 100, the weight table 133 and the weight 135 project to the left and right, and the casing 1 through the through-hole 180 can be moved to the corner portion to perform work regardless of the direction of installation. There wasn't. For this reason, conventionally, a leader pile driver equipped with an auger in addition to the tubing device 100 has to be prepared, which has been troublesome and costly.

  Therefore, an object of the present invention is to provide a tubing device with a reaction force weight suitable for work in a corner portion, in order to solve such a problem.

  In the tubing device with reaction force weight according to the present invention, an elevating frame is provided so as to be movable up and down by a plurality of thrust cylinders with respect to a base frame, and the elevating frame is provided with a chuck mechanism that can be rotated by a motor. The cylinder passing through the through hole is gripped by the chuck mechanism, and the rotation by the motor and the raising / lowering operation by the thrust cylinder are transmitted to the cylinder, and the horizontal jack cylinder for leveling protrudes from the lower surface of the base frame. The reaction force weight disposed in the lower space is connected to and integrated with the base frame.

Further, in the tubing device with reaction force weight according to the present invention, the reaction force weight is an iron plate formed in substantially the same size as the base frame, and a circular hole formed in accordance with the through hole, It is preferable that a notch is formed in accordance with the position of the horizontal jack cylinder.
Moreover, the tubing device with reaction force weight according to the present invention is provided at one corner portion of the outer diameter of the substantially rectangular shape of the device projected on the horizontal plane among the plurality of thrust cylinders provided around the through hole. It is preferable that one unit is disposed at each of two corners adjacent to each other, and the rotation driving unit including the motor is disposed on the sides excluding both sides sandwiching the corners.

  In the tubing device with reaction force weight according to the present invention, the chuck mechanism is provided such that the chuck frame can be moved up and down by a plurality of chuck cylinders relative to the lifting frame, and the lifting frame has a cone that can be rotated by a motor. The chuck is inserted between the cylinder through the through-hole of each frame and the cone by driving the chuck cylinder to grip the cylinder, and the thrust cylinder and the chuck cylinder are arranged coaxially. It is preferable that

In addition, the reaction force weight for a tubing device of the present invention is attached to a tubing device that pushes or pulls it into the ground while rotating the gripped cylindrical body, and can be attached under the base frame of the tubing device. It is an iron plate having a size substantially the same as that of the base frame or a size smaller than the base frame.
In addition, the reaction force weight for the tubing device according to the present invention is formed with a hole or a notch in accordance with the position of the through hole or the horizontal jack cylinder of the tubing device, and the pins are passed through the mounting brackets with respect to the base frame. It is preferably a pin-coupled one.

According to the present invention, since the reaction weight is mounted under the base frame, there is no lateral overhang as in the prior art, and a cylindrical body such as a casing inserted into the through hole is brought closer to the corner portion. It becomes possible to do so.
In addition, since the lifting and lowering unit composed of a plurality of cylinder mechanisms and the rotational driving unit including the motor are distinguished from each other, the number of components that limit the positions of the through holes is reduced. Work can be done with the body close to the corner.

  Next, an embodiment of a tubing device with reaction force weight according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a tubing device with reaction force weight according to the present embodiment, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is a sectional view thereof.

  A reaction force weighted tubing device (hereinafter simply referred to as “tubing device”) 10 includes a base frame 11 having four thrust cylinders 15, 15. A frame 13 is attached so as to be movable up and down. The base frame 11, the elevating frame 12, and the chuck frame 13 are all formed with through holes 80 having a diameter that allows the cylindrical casing 1 to pass therethrough, and are provided by four thrust cylinders 15, 15,. It is constructed integrally. Here, FIG. 5 is an enlarged sectional view of the cylinder mechanism.

  The cylinder tube 501 of the thrust cylinder 15 is directly fixed to the base frame 11. The cylinder tube 501 plays the role of the post 111 in the conventional tubing device 100 so as to guide the lifting and lowering of the lifting frame 12. Therefore, it is formed by a thick pipe having sufficient rigidity to support the lifting and lowering of the lifting frame 12 and the like. The cylinder tube 501 is directly fitted with the lifting guide 16 provided on the lifting frame 12. The lifting guide 16 is provided with a bush on the inner peripheral surface side, and is in sliding contact with the outer peripheral surface of the cylinder tube 501.

  In the thrust cylinder 15, the piston rod 502 protrudes upward, and a ring 503 formed at the tip of the thrust cylinder 15 is pivotally attached to the connecting member 17. The cylinder tube 501 is covered with a chuck post 19, which is fixed to the lifting frame 12. The chuck post 19 protrudes above the cylinder tube 501, and the connecting member 17 is assembled to that portion. Thus, the elevating frame 12 is moved up and down via the chuck post 19 when the thrust cylinder 15 expands and contracts.

  A chuck cylinder 18 is coaxially provided above the thrust cylinder 15. The piston rod 802 protrudes downward, and a ring 803 formed at the tip is pivotally attached to the connecting member 17. On the other hand, a chuck guide 21 that guides the sliding of the chuck frame 13 is fitted to the chuck post 19. The chuck guide 21 includes a bush on the inner peripheral surface thereof, and is in sliding contact with the outer peripheral surface of the chuck post 19. The upper end of the chuck guide 21 is fixed to the chuck frame 13, and the cylinder tube 801 of the chuck cylinder 18 is fixed to the chuck frame 13 via the fixture 22. Accordingly, the expansion and contraction of the chuck cylinder 18 moves the chuck frame 13 up and down via the fixture 22.

  In the tubing device 10 of the present embodiment, the thrust cylinder 15 and the chuck cylinder 18 are thus coaxially connected to form a cylinder mechanism 20 (20A to 20D), and the four cylinder mechanisms 20 penetrate as shown in FIG. The holes 80 are arranged close to each other. As shown in FIG. 1, the four cylinder mechanisms 20 are arranged at equal intervals in the circumferential direction so that the two cylinder mechanisms 20A and 20B located at the ends of the apparatus are separated from each other. This is because the through holes 80 are configured to be as close to the left side of the drawing of the tubing device 10 as possible with a gap between the cylinder mechanisms 20A and 20B. The chuck frame 13 is formed in such a size that the four cylinder mechanisms 20 are arranged.

  On the other hand, the elevating frame 12 has a thick ring member 25 (see FIG. 4) inside, the rotation drive unit frame 26 is fixed so as to protrude horizontally, and the weight 27 is fixed on the opposite side. ing. The weight 27 is formed by laminating a plurality of thick plates into upper and lower parts having different shapes, and a thrust cylinder 15 is penetrated through the upper part. Two motors 31 are fixed to the rotation drive unit frame 26, and their positions are arranged outside the chuck frame 13 as shown in FIG. 1.

  The tubing device 10 according to the present embodiment is an abbreviation of a device in which a lifting unit composed of a plurality of cylinder mechanisms 20 provided around the through hole 80 and a rotation driving unit composed of a motor 31 and a speed reducer 32 are projected on a horizontal plane. As shown in FIG. 1, the position of the through-hole 80, that is, the position of the casing 1, is arranged to distinguish between one end side of the outer shape having a rectangular shape (the shape of the base frame 11) and the other end side opposite thereto. The structure which was approached to one side of is taken. Since the motor 31, the speed reducer 32, and the like are biased to one side, a weight 27 is provided on the opposite side to balance the weight.

  The elevating frame 12 is provided with a rotation drive mechanism that transmits rotation from the motor 31 to the cone 35 disposed so as to surround the through hole 80. That is, a reduction gear 32 is connected to the motor 31, and high-torque rotation with a reduced number of rotations is transmitted to the pinion gear 33. Specifically, a pinion gear 33 and an idler gear 34 that are rotatably supported in the rotation drive unit frame 26 mesh with each other, and the idler gear 34 meshes with a gear formed on the outer peripheral surface of the cone 35. The cone 35 is rotatably attached to the lifting frame 12 by a bearing 36.

  The cone 35 is a cylindrical body formed with a predetermined diameter so that there is a gap between the cone 1 and the inner surface of the cone 35 is inclined so that the diameter decreases downward. A plurality of tapered grooves are formed. In the tubing device 10, a plurality of chucks 41 fitted in the taper grooves are arranged on the same circumference, and configured to grip the casing 1 through the through hole 80 from the outside. The chuck 41 has a vertical gripping surface for gripping the casing 1 on the inner side, and a taper groove on the cone 35 on the opposite outer side so that the gripping surface comes into contact with the casing 1 in an upright state without tilting. It has a wedge shape with an inclined surface of the same angle.

  The chuck 41 is suspended from the chuck frame 13 via a bearing 42 and a link 43. The outer ring of the bearing 42 is fixed to the chuck frame 13, and the chuck 41 is attached to the shaft via a link 43 connected to the rotating inner ring side. Therefore, the chuck 41 is attached to be freely rotatable by the bearing 42 and has an attachment structure that can be displaced in the horizontal direction by the link 43. The chuck 41 attached in this way is integrated with the chuck frame 13 to move up and down by expansion and contraction by the chuck cylinder 18 so as to grip and release the casing 1.

  Incidentally, the base frame 11 of the tubing device 10 is formed in a substantially rectangular shape larger than the lifting frame 12 and the chuck frame 13 as shown in FIG. Then, the chuck frame 13 is disposed so as to be biased to one side in the longitudinal direction with respect to the base frame 11, and a through hole 80 is formed. The base frame 11 is provided with horizontal jack cylinders 45 at the four corners. The two on the side where the chuck frame 13 overlaps are provided coaxially with the thrust cylinder 15 and the chuck cylinder 18 of the cylinder mechanisms 20A and 20B. Yes. The remaining two are provided at the corners on the motor 31 side. A plurality of brackets 46 are attached to the base frame 11 in order to connect an external beam that takes a rotational reaction force.

  Further, in the present embodiment, a reaction force weight for taking a pushing reaction force is arranged below the base frame 11. The base frame 11 is provided with the horizontal jack cylinders 45 at the four corners as described above. The horizontal jack cylinder 45 is fixed by the mounting flange 51 and protrudes from the lower surface of the base frame 11 even in a contracted state. Therefore, in the tubing device 10, the base frame 11 is located at a certain height from the ground, and a space is formed below the base frame 11. In the present embodiment, the reaction force weight is attached using such a space that is free under the base frame 11.

  Here, FIG. 6 is a view showing the reaction force weight 55. The reaction force weight 55 includes three thick steel plates 55a, 55b, and 55c which are integrally formed by welding. The reaction force weight 55 is a plate-like weight formed in accordance with the space below the base frame 11, and is formed with substantially the same size so as not to protrude from the base frame 11. The four corners are cut out so that the horizontal jack cylinder 45 is not covered, and the iron plate 55a is further cut away by the amount of the mounting bracket 56 fixed to the iron plate 55b. A through hole 57 of the same size is formed in the reaction force weight 55 so as to overlap the through hole 80 of the tubing device 10. On the other hand, a mounting bracket 48 for mounting the reaction force weight 55 by pin coupling projects downward from the base frame 11 of the tubing device 10.

Next, construction using the tubing device 10 having such a configuration will be described. Here, FIG. 7 is a plan view showing the tubing device 10 when the corner portion is constructed. FIG. 8 shows the installation work of the tubing device, and FIG. 9 shows the tubing device that has been leveled.
First, the reaction force weight is suspended and conveyed by a crane and installed at the driving position of the casing 1. And the tubing apparatus 10 suspended with the crane is conveyed to the position, as shown in FIG. The tubing device 10 is lowered so that the mounting bracket 48 is inserted into the bifurcated mounting bracket 56 of the reaction force weight 55. Then, the pins are passed through the overlapping holes of both the mounting brackets 48 and 56 to perform pin coupling.

After the reaction force weight 55 is mounted on the tubing device 10 in this way, the horizontal jack cylinder 45 is expanded and contracted, and leveling as shown in FIG. 9 is performed so that the casing 1 can be driven vertically. The reaction force weight 55 is attached to be suspended and integrated with the base frame 11.
As shown in FIG. 7, the tubing device 10 is arranged in such a direction that the cylinder mechanisms 20A, 20B on the chuck frame 13 side are located on the wall K2, and the cylinder mechanisms 20A, 20D are located on the wall K1, and the through hole 80 is a corner. To approach. A beam 50 is pivotally attached to the bracket 46 of the base frame, and the beam 50 is fixed by a spike or a working machine (not shown).

  Subsequently, after the casing 1 is passed through the through holes 80 of the frames 11, 12, and 13 in the tubing device 10, the chuck cylinder 18 is contracted. Since the piston cylinder 802 side of the chuck cylinder 18 is connected to the connecting member 17 and is stationary, the cylinder tube 801 side is lowered, and the chuck frame 13 is further lowered via the fixture 22. At this time, the chuck guide 21 slides on the chuck post 19, so that the horizontal state of the chuck frame 13 is maintained.

  When the chuck frame 13 is lowered, the position of the chuck 41 is similarly lowered and inserted between the casing 1 and the cone 35. The chuck 41 slides in the tapered groove of the inserted cone 35, and the contraction force of the chuck cylinder 18 becomes a horizontal component force to press the casing 1 in the axial direction from the outside. The plurality of chucks 41, 41... Are pressed in the same manner from around to hold the casing 1, so that the cone 35 and the casing 1 are integrated.

  Next, rotational press-fitting is performed on the casing 1 held by the chuck 41. For this purpose, the two motors 31 are driven, and the rotational output thereof is decelerated by the reduction gear 32 and transmitted to the cone 35 through the pinion gear 33 and the idler gear 34 as a high torque rotation. As the cone 35 rotates, the casing 1 held by the chuck 41 rotates. The tubing device 10 performs press-fitting into the ground as the casing 1 rotates, and this is done by lowering the lifting frame 12 by the contraction of the thrust cylinder 15.

  That is, when the extended thrust cylinder 15 contracts, the piston rod 502 enters the cylinder tube 501 on the fixed side. Therefore, due to the contraction of the piston rod 502, the chuck post 19 and the lifting frame 12 are lowered via the connecting member 17. When the elevating frame 12 is elevated, the elevating guide 16 slides on the cylinder tube 501, and the horizontal state of the elevating frame 12 is maintained. Since the rotational press-fitting by the tubing device 10 can only be lowered by one stroke of the thrust cylinder 15 at a time, the gripping by the chuck 41 is repeated and performed stepwise.

  On the other hand, in the all casing method, for example, the earth and sand inside the casing 1 is discharged while the casing 1 is press-fitted in this way, a reinforcing bar is built there, and the casing 1 is pulled out and collected while pouring concrete. To pull out the casing 1, first, the chuck 41 is inserted between the cone 35 and the casing 1 by the chuck cylinder 18. In such a gripping state, the thrust cylinder 15 is extended, and the elevating frame 12 is pushed up. In such operations, the extraction of the stroke of the thrust cylinder 15 is repeated.

When the casing 1 is rotationally press-fitted into the ground in this way, the tubing device 10 receives an indentation reaction force or a rotation reaction force due to its resistance. The indentation reaction force can increase the weight of the lower part of the tubing device 10 by the reaction force weight 55 provided under the base frame 11, and can prevent lifting. Also. In addition to the reaction force weight 55, it is held by a work machine or the like via the beam 50, so that it can receive a rotational reaction force.
According to the tubing device 10 of the present embodiment, the reaction weight 55 is thus mounted under the base frame 11, so that there is no overhang as in the conventional case, and the casing 1 inserted into the through hole 80. It is now possible to bring the closer to the corner. Further, in the present embodiment, the casing 1 can be brought closer to the corner portion from the structure of the tubing device 10 itself.

  That is, the arrangement of the elevating part corresponding to the area of the chuck frame 13 where the cylinder mechanism 20 is arranged and the rotation driving part corresponding to the area of the rotation driving part frame 26 where the motor 31 and the speed reducer 32 are arranged are divided. By adopting a structure in which the rotation drive unit is arranged on the side other than the corner part, the number of components that limit the position of the through hole 80 is reduced, and the position of the through hole 80 can be brought closer to the corner of the apparatus. I can do it now. More specifically, as shown in FIG. 1, the chuck frame 13 can be arranged on one side of the base frame 11 in the longitudinal direction, whereby the through holes 80 are formed in the cylinder mechanisms 20A and 20B and the cylinder mechanisms 20A and 20D. We were able to get close to the corner of the device where is located. Therefore, as shown in FIG. 7, it is possible to make the casing 1 inserted into the through hole 80 closer to the corner portion than in the prior art. In addition, by making it possible to work at the corner, which has been impossible until now, a leader pile driver and the like that had to be prepared only for the work at the corner becomes unnecessary, and the labor of transportation is eliminated. It also reduced costs.

In the tubing device 10, the cylinder mechanism 20 is configured such that the thrust cylinder 15 and the chuck cylinder 18 are coaxial, or the cylinder tube 501 of the thrust cylinder 15 is configured to slide up and down the guide 16. By reducing the diameter of 20, the casing 1 can be made closer to the corner.
Further, as shown in FIG. 7, since the cylinder mechanisms 20A and 20B located at the end of the apparatus are separated from each other, the through hole 80 can be brought close to the end of the apparatus (the right end in the drawing), and is very close to the wall K2 in the drawing. It became possible to approach. Therefore, the tubing device 1 can make the casing 1 close to the corner portion, and can be operated with being very close to the boundary of the construction site.

As described above, the tubing device with reaction force weight according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
In the above-described embodiment, a special mechanism configuration is provided so as to approach the corner portion. However, a configuration in which a weight is disposed under the base frame of the conventional tubing device illustrated in FIG. 10 may be used, and a wedge-shaped chuck 41 is used as the chuck mechanism. However, in addition to this, a tubing device provided with a band chuck type chuck mechanism may be used.
In the above embodiment, the reaction force weight 55 is formed in accordance with the shape of the base frame 11, but the shape is not limited as long as the configuration is arranged below the base frame 11.
