Description

Technical Field

[0001] This invention relates to a pole clamping device for reinforcing the lower support of a utility pole by installing it on one side of the lower part of the pole on which the power distribution line is suspended in the air to enhance its support to the ground. Background Technology

[0002] When installing utility poles to support overhead utility poles, a reinforcement device can be installed at the bottom of the pole to prevent it from falling or tilting. The reinforcement device consists of a reinforcement block (a concrete structure of a certain size), U-shaped bolts (U-bolts) for fixing the reinforcement block to the utility pole, and nuts.

[0003] This clamping device is installed by means of the following method: using manpower or equipment, the clamping block is pressed tightly against the side surface of the pole to be installed. After inserting the U-bolt into the through hole formed by the clamping block, the pole is positioned inside the pole. Then, the nut is tightened to press the pole and the clamping block tightly against each other and fix them in place.

[0004] However, because the clamping blocks are heavy concrete structures, they are difficult to transport to the construction site, and sometimes unnecessary labor is wasted in manually moving them back to the perimeter of the pole. Furthermore, because the pole is trapezoidal and its diameter narrows as it moves upwards, continuous application of external force to the pole can cause the U-bolts to loosen and create gaps, thus reducing its load-bearing capacity. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a pole clamping device that allows for easy selection of the installation position of the clamping device on the outer periphery of the pole.

[0006] According to an embodiment of the present invention, a pole clamping device for reinforcing the lower support of a utility pole includes: a support frame disposed in a disc shape along the outer periphery of the lower end of the utility pole, having a mounting surface and a sliding guide rail disposed circumferentially on the mounting surface; a clamping body extending laterally relative to the vertical direction of the utility pole, disposed on the mounting surface of the support frame, having a sliding portion on its bottom surface facing the mounting surface that engages with the sliding guide rail for sliding along the sliding guide rail, and configured to select a position relative to the outer periphery of the utility pole; and a connecting portion for fixing the positioned clamping body to the utility pole. Thus, by sliding the clamping body along the sliding guide rail of the support frame disposed along the outer periphery of the lower end of the utility pole, the mounting position of the clamping device relative to the outer periphery of the utility pole can be conveniently selected.

[0007] Here, the joint may include a U-bolt, with the clamping body equipped with a bolt-through-gap for the U-bolt to pass through, and having a permissible length in the lateral direction based on the stacking height of two or more clamping bodies. Thus, with two or more clamping bodies positioned on the same plane, they are fixedly joined to the outside of the utility pole, thereby further strengthening the pole's support, and the position of each clamping body can be selected by utilizing the sliding of a support frame.

[0008] Furthermore, according to an embodiment of the present invention, a method for supporting and reinforcing the lower part of a utility pole using a pole clamping device includes the following steps: providing a support frame along the outer periphery of the lower end of a utility pole that is embedded in a base surface, the support frame having a disc-shaped mounting surface and a sliding guide rail circumferentially arranged on the mounting surface; placing a clamping body on the mounting surface of the support frame, the clamping body having a sliding portion that engages with the sliding guide rail on its bottom surface facing the mounting surface; sliding the clamping body placed on the mounting surface along the sliding guide rail to select a position of the clamping body relative to a position on the utility pole; and using a connecting portion to engage and fix the positioned clamping body to the utility pole. Thus, by sliding the clamping body along the sliding guide rail of the support frame provided along the outer periphery of the lower end of the utility pole, the installation position of the clamping device relative to the outer periphery of the utility pole can be conveniently selected.

[0009] According to one embodiment of the present invention as described above, by sliding the clamping body along the sliding guide rail of the support frame provided along the outer periphery of the lower end of the utility pole, the installation position of the clamping device relative to the outer periphery of the utility pole can be conveniently selected.

[0026] Explanation of reference numerals in the attached figures Detailed Implementation

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate practice by those skilled in the art.

[0028] According to an embodiment of the present invention, the pole clamping device 10 is a pole lower support and reinforcement device, buried underground at the lower part of the pole 1, used to strengthen / reinforce the support of the pole 1 for overhead power distribution lines.

[0029] According to one embodiment, the utility pole 1 is a concrete utility pole (pole) in the form of a support column, used to support overhead power lines (such as power lines, communication lines, etc.). However, the present invention does not limit the material or shape of the utility pole 1; for example, the present invention also includes cases where the utility pole 1 is a steel pole made of steel pipe.

Figure 4 This is a perspective view of the utility pole clamping device after horizontal expansion. Figure 5 yes Figure 3 Side sectional view of the clamping device for the middle utility pole. Figure 6 and Figure 7 This is a diagram illustrating the span of the pole clamping device adjusted by sliding, according to the first invention.

[0031] Now for reference Figures 2 to 7 According to the first embodiment, the pole clamping device 10 includes a support frame 100 installed on one side of the lower end of the pole 1, and a pair of clamping bodies 210, 220 disposed within the support frame 100.

[0032] The support frame 100 is fixedly installed on the periphery of the lower end of the utility pole 1. In one embodiment, the support frame 100 may be made of metal steel sheet, such as, but not limited to, galvanized steel sheet.

[0033] According to one embodiment, the support frame 100 includes a top surface 110 and a bottom surface 120, which are U-shaped, open on both sides, and arranged parallel to each other at predetermined intervals in the lateral direction (e.g., horizontal direction) relative to the vertical direction of the pole 1; a back surface 130, which is arranged parallel to the vertical direction of the pole 1 and connects the top surface 110 and the bottom surface 120; and an adhesive surface 140. Here, the adhesive surface 140 is an inner surface that adheres to the outer circumference of the pole 1, and can be formed into an arcuate surface corresponding to the curvature of the outer circumference of the pole 1. In one embodiment, the lateral width of the support frame 100 is smaller than the width of the joint 300, which will be described later.

[0034] The top surface 110 and the bottom surface 120, at their two ends that contact the outer circumference of the utility pole 1, are provided with bent fasteners 111 and 121 in opposite directions (i.e., upward and downward, respectively). Each fastener 111 and 121 has bolt holes 112 and 122, so that the support frame 100 can be fixedly installed on the outer circumference of the utility pole 1 by bolts.

[0035] There is a hole 131 in the center of the back 130, through which the rotary control hole 430, described later, can be inserted. On the left and right sides of the opening 131 there is a pair of support protrusions 132, 133, which extend from the back 130 toward the utility pole 1 and are used to support and slide a pair of clamping bodies 210, 220.

[0036] The clamping bodies 210, 220 are arranged on the support frame 100 and are parallel to each other vertically relative to the upright direction (e.g., the vertical direction) of the utility pole 1. In one embodiment, the clamping bodies 210, 220 may be made of concrete or metal, such as, but not limited to, hot-dip galvanized steel.

[0037] A pair of clamping bodies 210 and 220 extend laterally (e.g., horizontally) along the vertical direction of the utility pole 1 and are arranged to slide relative to each other laterally. Here, as the pair of clamping bodies 210 and 220 slide laterally, they may move closer together or spaced apart, and the overall width W of the pair of clamping bodies 210 and 220 can be adjusted (decreased or increased) accordingly. For example, refer to... Figure 6 and Figure 7 When the pair of clamping bodies 210 and 220 slide away from each other, the total width W of the pair of clamping bodies 210 and 220 increases, thereby causing the clamping device 10 to extend horizontally.

[0038] According to one embodiment, each clamping body 210, 220 is arranged to have a tapered outer end. For example, the outer end of the clamping body 210 may have multiple tapered inclined inner surfaces 211, 212, and the outer end of the clamping body 220 may form multiple tapered inclined inner surfaces 221, 222.

[0039] Since the outer ends of each clamping body 210, 220 are made of paper, during the horizontal expansion of the clamping device 10, each clamping body 210, 220 can easily be driven into the ground by the mutual sliding of a pair of clamping bodies 210, 220.

[0040] The pole clamping device 10 includes a coupling 300 for fixing a pair of clamping bodies 210, 220 to the pole 1.

[0041] According to one embodiment, the joint 300 includes a U-bolt 310 with generally U-shaped threaded portions 311, 312 (external threaded portions) formed on the outer circumference of both ends, and nuts 321, 322 fastened to the threaded portions 311, 312 of the U-bolt 310. Here, as described above, the width of the support frame 100 in the lateral direction is arranged to be smaller than, for example, the horizontal distance between the threaded portions 311, 312 of the joint 300. The nuts 321, 322 corresponding to the threaded portions 311, 312 can be easily fixed to each threaded portion 311, 312 from the rear 130 side of the support frame 100 by bolts passing through gaps 213, 223 as described below.

[0042] Each clamping body 210, 220 has a bolt passing through the slots 213, 223, through which the threaded portions 311, 312 of the U-bolt 310 pass. The U-bolt 310 can be fastened with nuts 321, 322, whose threaded portions 311, 312 pass through the corresponding bolts passing through the slots 213, 223 and protrude to the rear of the clamping body 210, 220.

[0043] According to one embodiment, the permissible length of the bolt passing through the slots 213, 223 is consistent with the lateral sliding length of the pair of clamping bodies 210, 220. That is, the bolt is elongated laterally (i.e., horizontally) through the slots 213, 223 so that after the threaded portions 311, 312 of the U-bolt 310 pass through the slots 213, 223 and are fastened with the nuts 321, 322, the pair of clamping bodies 210, 220 are allowed to slide freely into or out of each other.

[0044] The U-bolt 310 includes a centrally located bent portion 313 and inclined extension portions 314 and 315 extending obliquely on both sides of the bent portion 313.

[0045] The arc-shaped portion 313 supports the utility pole 1, surrounds the utility pole 1 from the outside, and is arranged horizontally relative to the vertical direction of the utility pole 1.

[0046] Inclined extensions 314 and 315 are provided on both sides of the bend 313 to allow bolts entering each clamping body 210 and 220 at an angle through the slits 213 and 223. Here, the pair of clamping bodies 210 and 220 are arranged vertically parallel, and the bolts passing through the slits 213 and 223 of each clamping body 210 and 220 are also arranged vertically parallel, giving them different heights. The inclined extensions 314 and 315 on both sides of the bend are arranged to be inclined in opposite directions (e.g., upward and downward) towards the corresponding bolts passing through the slits 213 and 223. At both ends of each inclined extension 314 and 315, parallel threaded portions 311 and 312 are provided for the corresponding bolts to pass through the slits 213 and 223.

[0047] Such a joint 300 can be tightly wrapped around the lower outer circumference of the utility pole 1 by the bent part 313 of the supporting U-bolt 310, and the bolts passing through the corresponding utility pole clamping bodies 210 and 220 through the threaded parts 311 and 312 at both ends pass through the gaps 213 and 223 and are fastened to the nuts 321 and 322 respectively, so as to firmly fasten a pair of clamping bodies 210 and 220 to the utility pole 1.

[0048] The pole clamping device 10 includes an extension adjustment section 400 for adjusting the overall width of a pair of clamping bodies 210, 220.

[0049] According to one embodiment, the extended adjustment unit 400 includes a pair of racks 410, 420, which are fixedly mounted on opposite surfaces of a pair of clamping bodies 210, 220, respectively, and a pinion 430 fastened between the pair of racks 410, 420.

[0050] The pair of racks 410, 420 and pinion 430 are made of a metallic material, such as, but not limited to, carbon steel, alloy steel, stainless steel, aluminum, copper, brass, etc. In one embodiment, the pair of racks 410, 420 are bonded to one side (facing one side) of the corresponding clamping bodies 210, 220, wherein epoxy resin adhesive, silicone adhesive, or similar materials capable of bonding metal to concrete can be used. However, the connection between the racks 410, 420 and the clamping bodies 210, 220 is not limited to bonding; they can also be bolted to the clamping bodies 210, 220, for example, by forming bolt holes at both ends of the pair of racks 410, 420.

[0051] The pinion 430 can be rotated by operating the rotary manipulator 440. The pinion 430 has a connector 431 to which the rotary manipulator 440 can be connected.

[0052] In one embodiment, the rotary manipulator 440 includes an L-shaped wrench with a hexagonal cross-section. The connector 431 is in the form of a hexagonal groove with a predetermined depth into which the front end 441 of the rotary manipulator 440 can be tightly inserted. The rotary manipulator 440 can be operated manually or electrically.

[0053] Therefore, when the connector 431 is inserted (i.e. fastened) at the front end 441 of the rotary manipulator 440, the pinion 430 can be rotated by manipulating the rotary manipulator 440. As the pinion 430 rotates, the pair of racks 410 and 420 fastened to it move in opposite directions, i.e., they make linear motion.

[0054] Reference Figure 6 and Figure 7The mutual movement of the racks 410 and 420 in response to the rotation of the pinion 430 causes the clamping bodies 210 and 220 to slide into or out of each other in the lateral direction, thereby adjusting the overall width of the clamping bodies 210 and 220. For example, when the pinion 430 rotates in one direction (such as counterclockwise), the mutual movement of the racks 410 and 420 causes the clamping bodies 210 and 220 to slide apart, thereby increasing the span of the clamping bodies 210 and 220, and the clamping device 10 expands horizontally accordingly.

[0055] According to the first embodiment of the present invention described above, a method for reinforcing the lower support of a utility pole 1 using a utility pole clamping device 10 is described.

[0056] First, dig a pit at the location where you want to hang utility pole 1, and then erect utility pole 1.

[0057] According to one embodiment, an operator (user) excavates a pit (pole hole) (h), for example using a auger crane, to the proximal penetration depth of the utility pole 1 to be erected in the installation ground (g). The pit (pole hole) (h) can be excavated using a rotary drilling rig.

[0058] At this point, the space a for installing the pole clamping device 10 is further excavated to ensure that there is a space (proximity footprint) a for installing the pole clamping device 10. The arrangement of the space (a) near the pole allows the pole clamping device 10 to be installed above the depth (h) of the pole hole and below the ground. In one embodiment, the width of the pole footprint A is consistent with the total width of the pair of pole clamping bodies 210, 220 before extension (see...). Figure 6 (a)). However, in some cases, the width of the proximal footprint A can take into account the full width after expansion (see (a)). Figure 6 (b) in the middle.

[0059] Then, insert the lower end of pole 1 into the excavated pit (pole hole) h, thereby erecting pole 1. At this time, the lower end of pole 1 can be temporarily embedded into the installation ground (g).

[0060] The utility pole 1, which is erected and buried underground, is equipped with a utility pole clamping device 10.

[0061] According to one embodiment, the pole clamping device 10 installed on the pole 1 includes a support frame 100 on which a pair of clamping bodies 210 and 220 are mounted.

[0062] A pair of clamping bodies 210, 220 are arranged vertically and parallel to each other relative to the vertical direction of the utility pole 1, supported by a pair of support protrusions 132, 133 extending from the rear surface 130 of the support frame 100, with a pinion 430 arranged between them. Here, a pair of racks 410, 420 are respectively provided on opposite sides of the pair of upward and downward arranged clamping bodies 210, 220 to fasten the pinion 430, so that the pair of racks 410, 420 can move relative to each other in opposite directions as the pinion 430 rotates.

[0063] In this way, the support frame 100 with clamping bodies 210 and 220 is fixedly installed on one side of the lower end of the upright utility pole 1.

[0064] Then, a pair of clamping bodies 210, 220 mounted on the support frame 100 are attached to the utility pole 1 via the joint 300.

[0065] For example, the operator connects a pair of clamping bodies 210, 220 to the utility pole 1 by inserting the threaded portions 311, 312 at both ends into the bolts formed in each clamping body 210, 220 through the gaps 213, 223, while pressing the bent portion of the U-bolt 310 against the utility pole 1 from the outside, and then tightening the nuts 321, 322.

[0066] In one embodiment, the fastening between the threaded portions 311, 312 of these U-bolts 310 and the nuts 321, 322 is a temporary fastening (primary fastening) to prevent the fastening device 10 from moving relative to the utility pole 1, so that a full fastening (secondary fastening) can be performed subsequently to securely fasten the pair of fastening bodies 210, 220 to the utility pole 1.

[0067] Once the clamping bodies 210, 220 are thus attached to the utility pole 1, the area A occupied by the utility pole will be backfilled to bury the clamping device 10. At this time, the backfilling work does not include the area around the through hole 131 formed in the rear 130 of the support frame 100.

[0068] Then, the operator on the ground inserts the front end 441 of the rotation control shaft 430 into the hole 131, connects (tightens) it to the connection 431 of the pinion 430, and operates the rotation control shaft 430 to rotate the pinion 430.

[0069] Here, the operator manipulates the rotary knob 430 to rotate the pinion 430 in a unidirectional (e.g., counterclockwise) direction on top of the pole clamping device 10 embedded in the ground, excluding the area around the drill hole 131. As the pinion 430 rotates via this operation of the rotary knob 430, a pair of racks 410, 420 move relative to each other, causing a pair of clamping bodies 210, 220 to slide at intervals, thereby increasing its overall width, and the clamping device 10 expands horizontally accordingly. At this time, the tapered outer ends of the pair of clamping bodies 210, 220 drill into the ground, thus stably supporting the pole clamping device 10.

[0070] Thus, once the pole clamping device 10 is reliably supported by the horizontal extension, the pair of pole clamping bodies 210 and 220 can be completely fastened to the pole 1 using the fastening part 300 (secondary fastening). That is, by fully fastening the threaded parts 311 and 312 of the U-bolt 310 and the nuts 321 and 322, the pair of pole clamping bodies 210 and 220 are fixedly fastened to the pole 1.

[0071] Then, the backfilling (final backfilling) of the support frame 100 on the rear 130 side is completed to finish the construction of the pole clamping device 10.

[0072] However, the construction sequence of the pole clamping device 10 is not limited to the above. For example, backfilling can be performed, placing the pair of clamping bodies 210, 220 on the support frame 100, fixing the support frame 100 on the pole 1, and then, according to the operation of the rotary manipulator 430, sliding the pair of clamping bodies 210, 220 horizontally to extend a certain distance, fixing the pair of clamping bodies 210, 220 to the pole 1 through the joint 300, and then embedding them into the installation space of the pole clamping device 10. Alternatively, as another example, the support frame 100 can be installed at the lower end of the pole 1, and then a pair of clamping bodies 210, 220 can be placed on the support frame 100.

[0073] Example 2 Figure 8 This is a schematic diagram illustrating a pole clamping device installed on a utility pole according to a second embodiment of the present invention. Figure 9 and Figure 10 These are perspective and sectional views of the pole clamping device according to a second embodiment of the present invention. Figure 11 This is a diagram illustrating the expansion deformation of the expansion deformation anchoring member in the pole clamping device according to the second embodiment of the present invention. Figure 12 This is a diagram illustrating the fixed support of a pole clamping device consisting of two clamping bodies according to a second embodiment of the present invention.

[0074] See Figures 8 to 10According to a second embodiment of the present invention, the pole clamping device 11 includes a clamping body 200, which is installed on one side of the lower end of the pole 1.

[0075] The clamping body 200 extends laterally (e.g., horizontally) relative to the upright direction (e.g., vertical direction) of the pole 1. Here, the clamping body 200 may form a tapered inclined surface at its outer end toward the pole 1, but is not limited to this.

[0076] In one embodiment, the clamping body 200 may be made of concrete or metal, such as, but not limited to, galvanized steel.

[0077] According to one embodiment, the clamping body 200 forms a through hole 230 at one location along the vertical direction of the utility pole 1. The through hole 230 is formed, for example, at the central portion of the clamping body 200. However, the location of the through hole 230 is not limited; as another example, the through hole 230 can be formed at one end of the clamping body 200, as described later. Figure 12 In the embodiments described above.

[0078] In one embodiment, the upper surface 220 of the main body 200 is tightened by a finger twist 221 along the inner circumference of the through hole 230, so that the expandable deformable fixing member 500 described later can be securely installed.

[0079] The pole clamping device 11 includes a coupling portion 301 for fixing the clamping body 200 to the pole 1.

[0080] According to one embodiment, the fastening part 301 includes a U-bolt 330 with U-shaped threaded portions 331 and 332 (external threads) formed on the outer circumference of both ends, and nuts 341 and 342 fastened to the threaded portions 331 and 332 of the U-bolt 330.

[0081] Each clamping body 200 has bolt through holes 241, 242 through which the threaded portions 331, 332 (external threads) of the U-bolts 330 pass. The U-bolts 330 can be fastened with nuts 341, 342, each threaded portion 331, 332 passing through the corresponding bolt holes 241, 242 and protruding to the rear of the clamping body 200.

[0082] The U-bolt 330 includes a centrally located curved portion 333. The curved portion 333 supports the utility pole 1, surrounds the utility pole 1 from the outside, and is arranged horizontally relative to the vertical direction of the utility pole 1.

[0083] Such a fastening part 301 can be tightly wrapped around the lower outer circumference of the utility pole 1 by supporting the bending part 333 of the U-bolt 330, and the threaded parts 331 and 332 at both ends pass through the bolt through holes 241 and 242 of the corresponding utility pole fastening body 200 and are fastened to the nuts 341 and 342 respectively, thereby firmly fastening the utility pole fastening body 200 to the utility pole 1.

[0084] The pole clamping device 11 includes an extended deformable fixing member 500 that provides fixed support between the pole clamping body 200 and the base layer.

[0085] The extended deformation fixing member 500 includes a tubular main body portion 510 inserted into the through hole 230 and a flange portion 511 on one side of the main body portion 510.

[0086] The main body 510 is tubular, that is, hollow cylindrical, with a cavity inside the cylinder, into which the expansion manipulator 530 described later can be inserted axially.

[0087] A flange 511 is provided on one side of the main body 510 for contacting and supporting the upper surface of the pole clamping body 200 with the vertical direction of the pole 1. Here, the flange 511 can be fixed to a threshold provided on the upper surface of the clamping body 200 to provide stable contact support for the upper surface.

[0088] In one embodiment, the flange 511 is continuously formed at a leading edge of the body portion 510. For example, the flange 511 is formed by horizontally bending and extending along the periphery of the body portion 510 starting from the leading edge, such that the leading edge is the entry point of the extension manipulator 530.

[0089] On the inner circumferential surface 512 of the main body 510, a threaded portion 513 (internal thread) is formed that can be fastened to the external thread 531 of the expansion actuator 530. Here, the threaded portion 513 is formed on the other side of the inner circumference, that is, on the area of ​​the inner circumferential surface 512 on the rear end side of the main body 510, so as to embed the clamping body 200 into the mounting base.

[0090] The extension manipulator 530 can be used as a fastening tool, such as a screwdriver, electric screwdriver, L-wrench, or similar tool, for fastening to the extended deformation fixing component 500. The extension manipulator 530 can be operated electrically or manually.

[0091] The first end of the expansion manipulator 530 is provided with an external thread 531, which can be threadedly fastened to the threaded portion 513 (internal thread) of the expansion deformation fixing component 500.

[0092] The extended deformation fixing component 500 includes a deformable portion 520 disposed between the threaded portion 513 and the flange portion 511. The deformable portion 520 can be radially extended and deformed about an axis by the operation of the extended actuator 530.

[0093] According to one embodiment, the deformable portion 520 is formed by forming a plurality of longitudinal stripes 521 (raised stripes) on the outer circumferential surface of the main body portion 510. The plurality of longitudinal stripes 521 can be formed by knurling or the like to create a plurality of axial grooves at equal intervals along the circumferential direction on the outer circumferential surface of the main body portion 510.

[0094] According to one embodiment, the deformable portion 520 has a plurality of grooves 522 formed in the form of longitudinal (axial) cuts along the circumferential direction of the main body portion 510. Triangular cutouts 523 may be provided on both sides of the central portion of the plurality of grooves 522. For example, four grooves 522 may be formed in the deformable portion 520, but this is not a limitation.

[0095] The deformable portion 520, with its multiple longitudinal stripes 521 and multiple grooves 522, serves as a vulnerable area to pressure (e.g., axial pressure) applied externally to the main body 510. Therefore, while the deformable portion 520 supports the flange 511, the radial expansion deformation along the axis is achieved through the operation of the expansion manipulator 530, and the expansion deformation fixing member 500 provides fixed support for the base layer to the clamping body 200.

[0096] According to the second embodiment of the present invention described above, a method for reinforcing the lower support of a utility pole 1 using a utility pole clamping device 11 is described.

[0097] First, dig a pit at the location where you want to hang utility pole 1, and then erect utility pole 1.

[0098] According to one implementation plan, an operator (user) digs a pit (pole hole), for example using a auger crane, to a depth close to the location of the utility pole 1 to be erected on the installation ground (g). The pit (pole hole) can be excavated using a rotary excavating drill.

[0099] At this point, the space for installing the pole clamping device 11 is further excavated to ensure sufficient installation space (near-ground installation space) for the pole clamping device 11. The arrangement of the near-ground installation space allows the pole clamping device 11 to be installed at a position higher than the depth of the pole hole but lower than the ground. In one embodiment, the width of the pole installation space is the same as the total width of the pole clamping body 200. However, in some cases, the width of the pole installation space can be slightly wider to facilitate the installation of the pole clamping device 11.

[0100] Next, insert the lower end of pole 1 into the excavated pit (pole hole). At this point, the lower end of pole 1 can be temporarily embedded in the ground where it will be installed.

[0101] Then, standing on the installation ground, place the clamping body 200 on one side of the lower end of the underground utility pole 1.

[0102] Next, the clamping body 200 is connected and fixed to the utility pole 1 using the connecting part 301.

[0103] For example, the operator can insert the threaded portions 331 and 332 at both ends into the bolt through holes 241 and 242 formed on the pole clamping body 200, and at the same time push the bent portion 333 of the U-bolt 330 so that it wraps around the pole 1 from the outside, and then tighten the nuts 341 and 342, thereby fastening and fixing the pole clamping body 200 to the pole 1.

[0104] After the pole clamping body 200 is connected and fixed to the pole 1, backfilling can be carried out to bury the pole clamping device 11 underground. In this case, the backfilling height should reach the top surface of the pole clamping body 200.

[0105] Next, the drill bit is inserted and drilled through the through hole 230 of the clamping body 200 to form a hole of a predetermined depth in the lower ground.

[0106] Then, the extended deformation fixing member 500 is inserted into the through hole 230, and the threaded part 513 and the deformable part 520 are embedded in the recessed hole 50. At this time, the flange part 511 of the extended deformation fixing member 500 will be fixed on the upper surface of the clamping body 200, so that the upper surface of the clamping body 200 can reliably contact the support.

[0107] Then, the expansion manipulator 530 is inserted into the main body 510 of the expansion deformation fixing member 500, the flange 511 is fastened to the threaded part 513, and it is supported on the upper surface of the clamping body 200, so that the deformation part 520 expands and deforms radially along the axis.

[0108] Here, the operator lowers the expansion manipulator 530 through the through hole 230 and pushes the external thread 531, which is fastened to the expansion manipulator 530, into the main body 510 of the expansion deformation fixing member 500. At this time, when the inserted external thread 531 descends to a position where it can be fastened to the threaded portion 513 (internal thread), the operator rotates the external thread 531 in the forward direction (e.g., clockwise) by operating the expansion manipulator 530 (e.g., a fastening tool), thereby threading the external thread 531 to the threaded portion 513 (internal thread).

[0109] See Figure 11 When the external thread 531 rotates in the forward direction, it generates axial pressure, which pulls the threaded part 513 (internal thread) upward through the thread fastening of the external thread 531 and the threaded part 513 (internal thread).

[0110] During this process, multiple longitudinal stripes 521 and multiple grooves 522 cause the center of the deformable part 520 to bend, and the resulting force causes the deformable part 520 to deform in the lateral direction, which is a vulnerable area. Since the deformable part 520 is embedded in the base layer, when the deformable part 520 bends in the oblique direction, the deformable part 520 can be deformed into a bend, that is, fold.

[0111] Therefore, at the top of the bending deformation 520, the increased ground density can more reliably support the clamping body 200, thus providing greater support force.

[0112] Then, when the operator operates the expansion manipulator 530 to rotate the external thread 531 in the opposite direction (counterclockwise), the external thread 531 disengages from the threaded portion 513 (internal thread), and the expansion manipulator 530 is removed. At this time, the expansion deformation fixing component 500 is inserted into the through hole 230 of the clamping body 200 to continue to provide fixed support for the clamping body 200 and the base layer.

[0113] After the clamping unit 11 is firmly supported on the base layer by the expansion deformation fixing component 500, the upper side of the clamping body 200 is backfilled (final backfilling) to complete the construction of the clamping unit 11.

[0114] In the second embodiment, the pole clamping device can be installed by stacking two root bodies 201 and 202 together and fixedly supported on the base layer by using an extended deformation fixing component.

[0115] See Figure 12 Through holes 231 and 232 are formed at one end of each rhizome 201 and 202 along the vertical direction of the stem 1.

[0116] Two near-root bases 201 and 202 are stacked into an L-shape, with the two ends having through holes 231 and 232 overlapping each other. At this time, the root bases 201 and 202 are stacked so that the two through holes 231 and 232 of the two root bases 201 and 202 are connected to each other.

[0117] In this case, the rootstocks 201 and 202 are stacked in an L-shape, and each rootstock is joined and fixed to the utility pole 1 by the joint 301.

[0118] Once each pole body 201 and 202 is connected and secured to pole 1, backfilling begins to bury the clamping device 11. In this case, the backfilling work continues up to the height of the stacked pole bodies 201.

[0119] Next, the drill bit is inserted and drilled through two consecutive through holes 231 and 232 of the two root bodies 201 and 202 to form a hole of predetermined depth on the lower ground. A single extended deformation fixing member 500 is then inserted into the consecutive through holes 231 and 232, and the threaded portion 513 and the deformable portion 520 are embedded in the drill hole. At this time, the flange portion 511 of the extended deformation fixing member 500 contacts and supports the upper surface of the stacked root body 201.

[0120] Then, as described above, by inserting the extension manipulator 530 into the main body 510 of the extension deformation fixing member 500 and fastening the threaded part 513 to the flange part 511 supported on the upper surface of the root body 201, the deformation part 520 can be stretched and extended in the radial direction of the axis to stably fix and support the two stacked root bodies 201, 202 on the bottom ground.

[0121] The pole root device of the present invention can be implemented by a combination of the above embodiments.

[0122] Figure 13 This is a schematic diagram illustrating an example of the application of the extended deformation fixing component of the second embodiment to the pole clamping device according to the first embodiment of the present invention.

[0123] Reference Figure 13 According to one embodiment, the pole clamping device 12 has a through hole (not shown) formed at a location on each of the pair of clamping bodies 210, 220 described in the first embodiment, along the vertical direction of the pole 1. In the first embodiment, the pair of clamping bodies 210, 220 are arranged within a support frame 100, and through holes 113, 114 are formed at corresponding locations on the upper surface 110 and lower surface 120 of the support frame 100. Here, each through hole 113, 114 communicates with a corresponding through hole of the pair of clamping bodies 210, 220 in a horizontally extending state. However, for example, the through hole may be formed outside the support frame 100 of each pair of rootstocks 110, 120.

[0124] A support frame 100, which holds a pair of clamping bodies 210 and 220, is attached to the utility pole 1, for example, by bolts. Alternatively, a connecting part 300 can be used to attach the pair of clamping bodies 210 and 220 to the utility pole 1. However, since the pair of clamping bodies 210 and 220 are attached to the utility pole 1 via the support frame 100, the use of the connecting part 300 can be omitted.

[0125] Once the support frame 100 and the pair of clamping bodies 210, 220 are securely connected to the utility pole 1, backfilling can proceed to bury the utility pole clamping device 12 underground. In this case, the backfilling operation continues up to the height of the upper surface 110 of the support frame 100.

[0126] Next, as described in the first embodiment, a rotating manipulator 430 is operated on the upper part of the pole clamping device 12, causing a pair of clamping bodies 210, 220 to slide at intervals. Therefore, the pole clamping device 10 extends horizontally.

[0127] Subsequently, a drill bit is inserted and drilled through the through holes 113 and 114 of the support frame 100 and the through holes of the subsequent clamping bodies 210 and 220 to form a hole of predetermined depth on the lower ground. Expansion deformation fixing members 501 and 502 are inserted into each hole, and the expansion deformation of the deformable part 520 is achieved by inserting an expansion manipulator 530 into the body portion 510 of the expansion deformation fixing members 501 and 502, as described in the second embodiment.

[0128] According to this embodiment of the invention, the horizontal extension and extension deformation of the pair of clamping bodies 210, 220 and the extension deformation fixing members 501, 502 can make the clamping device 12 more reliably fixed and supported in the base layer.

[0129] Example 3 Figure 14 This is a schematic diagram of a pole clamping device installed on a utility pole according to a third embodiment of the present invention. Figure 15 and Figure 16 These are perspective and sectional views of the edge of the base of a utility pole according to a third embodiment of the present invention. Figure 17 This is a schematic diagram of the support frame of the utility pole clamping device according to the third embodiment of the present invention. Figure 18 This is a schematic diagram of the sliding positioning of the utility pole clamping device according to the third embodiment of the present invention. Figure 19 This is a schematic diagram of a utility pole clamping device according to a third embodiment of the present invention. The device includes two clamping bodies that are fixedly connected for positioning around the outer pole of the utility pole.

[0130] Now please see Figures 14 to 19 The pole clamping device 13 includes a support frame 101 installed on one side of the lower end of the pole 1 and a rooting body 203 disposed within the support frame 101.

[0131] The support frame 101 is installed along the outer circumference of the lower part of the utility pole 1. In one embodiment, the support frame 101 may be made of sheet metal, such as, but not limited to, galvanized steel sheet.

[0132] According to one implementation, the support frame 101 has a disc-shaped support surface 150 and a sliding guide rail 160 circumferentially disposed on the support surface 150.

[0133] Here, the sliding guide 160 may be arranged in the form of a pivot guide that protrudes upward from the seat surface 150, but is not limited thereto. For example, the sliding guide may include a pivot guide that is recessed from the seat surface 150, or it may include two or more protruding or recessed guides.

[0134] In one embodiment, the support frame 101 includes a downwardly positioned flange 170. The flange 170 may be formed by bending and extending the inner circumference of the disc-shaped support frame 101 that contacts the rod 1 downwardly.

[0135] See Figure 17 Multiple (e.g., four) bolt holes 171, 172, 173, and 174 are formed on the flange 170, so that the support frame 101 can be fixedly installed on the outer circumference of the utility pole 1 by bolt fastening.

[0136] The root body 203 extends laterally (e.g., horizontally) relative to the upright direction (e.g., vertical direction) of the utility pole 1 and rests against the support surface 150 (top surface) of the support frame 101. Here, the root body 203 may form a tapered inclined surface facing the utility pole 1 at its outer end, but is not limited to this.

[0137] In one embodiment, the root body 203 may be made of concrete or metal, such as, but not limited to, galvanized steel.

[0138] The root body 203 has sliding parts 250 and 260, which are fastened to the sliding guide rail 160 on the lower surface facing the stationary surface 150.

[0139] According to one embodiment, the sliding components 250, 260 are implemented in the form of rotating rollers that contact both sides of a sliding guide 160 protruding from the stationary surface 150. Here, each sliding component 250, 260 (rotating roller) can be coupled to the lower surface of the root body 203 using bolts or the like.

[0140] However, the implementation of the sliding portions 250 and 260 in this invention is not limited to rollers, and various configurations capable of sliding along the sliding guide 160 can also be adopted. For example, a sliding portion in the form of a ball bearing can be provided on the bottom surface of the rhizome body 203 to slide along the sliding guide implemented as a recessed rotary guide. In addition, in some cases, the sliding portion may include a concave structure (e.g., a protrusion) that can slide along the sliding guide without rollers or bearings.

[0141] In one embodiment, the sliding portions 250 and 260, in the form of rotating rollers, each move along two sides (i.e., the inner and outer arc surfaces) of the sliding guide 160. (See reference...) Figure 18The movement of the sliding parts 250 and 260 causes the root body 203 to rotate along the outer circumference of the utility pole 1, thereby changing the installation position of the root body 203 relative to the outer circumference of the utility pole 1. Here, the changed installation position is the angular position relative to the outer circumference of the utility pole 1, such as including but not limited to 0° (360°), 45°, 90°, 120°, 135°, 180°, 225°, 240°, 270°, 295°, etc.

[0142] The pole fastening device 13 includes a joint 301 for fixing the pole body 203 to the pole 1.

[0143] According to one embodiment, the fastening part 301 includes a U-bolt 330 with U-shaped threaded portions 331 and 332 (external threads) formed on the outer circumference of both ends, and nuts 341 and 342 fastened to the threaded portions 331 and 332 of the U-bolt 330.

[0144] Bolts pass through gaps 251 and 252 on the root body 203, and the threaded portions 331 and 332 (external threads) of the U-bolts 330 pass through these gaps. The U-bolts 330 can be fastened with nuts 341 and 342, and each threaded portion 331 and 332 passes through the corresponding bolt gaps 251 and 252 and protrudes towards the rear of the rootstock 203.

[0145] The U-bolt 330 includes a centrally located curved portion 333. The curved portion 333 supports the utility pole 1, surrounds the utility pole 1 from the outside, and is arranged horizontally relative to the vertical direction of the utility pole 1.

[0146] Such a fastening part 301 can firmly fasten the pole body 203 to the utility pole 1 through the bending part 333 of the supporting U-bolt 330, so that it is tightly wrapped around the lower outer circumference of the utility pole 1. The threaded parts 331 and 332 at both ends pass through the bolts passing through the gaps 251 and 252 of the corresponding pole body 203 and are fastened to the nuts 341 and 342 respectively.

[0147] According to one embodiment, the allowable length of the bolt slots 251 and 252 is consistent with the overlap height of the two or more U-bolts 330 in the vertical direction (i.e., the longitudinal direction) of the pole 1. In other words, the bolts are longitudinally, that is, vertically elongated through the slots 251 and 252, so that the threaded portions 331 and 332 of the two or more overlapping U-bolts 330 from top to bottom can pass through the bolt slots 251 and 252 of the corresponding root body 203 and be fastened to the nuts 341 and 342 respectively.

[0148] The fastening part 301 supports the bending part 333 of the U-bolt 330, which tightly wraps around the lower outer circumference of the utility pole 1. The threaded parts 331 and 332 at both ends pass through the corresponding bolt through slots 251 and 252 on the utility pole body 203, and are fastened to the nuts 341 and 342, respectively, thereby firmly fixing the utility pole body 203 to the utility pole 1.

[0149] See Figure 19 One of the bases, namely the first base 204, is placed on the support surface 150 of the support frame 101 and slides along the sliding guide 160 using the sliding parts 250 and 260 on the lower surface to position the first base 201 at a position perpendicular to the outer circumference of the utility pole 1, for example, at an angle of 120°.

[0150] The first base body 201 is fixedly connected to the utility pole 1 via the connecting part 301, that is, each threaded portion 331, 332 of the U-bolt 330 passes through the bolt through holes 251, 252 of the first base body 201 and is fastened with nuts 341, 342. In this case, the bolt passing through the slits 251, 252 is vertically elongated, and the threaded portions 331, 332 can be located at the lower end of the bolt passing through the slits 251, 252.

[0151] Then, another rootstock, namely the second rootstock 205, is placed on the stationary surface of the support frame 101. The sliding parts 250 and 260 on the lower surface slide along the sliding guide rail 160 to position the second rootstock 205 at different working positions relative to the outer circumference of the utility pole 1, such as an angular position of 0°.

[0152] The second base body 202 is also fixedly connected to the utility pole 1 via the connecting part 301, that is, each threaded portion 331, 332 of the U-bolt 330 passes through the bolt-through slits 251, 252 of the second base body 205 and is fastened with nuts 341, 342. In this case, the bolts through the slits 251, 252 are arranged in a vertically elongated shape, so that the threaded portions 331, 332 can be located at the top of the bolt-through slits 251, 252.

[0153] Although Figure 16 The illustrated embodiment shows the installation positions of the first and second near-root bodies 204 and 205 spaced 120° apart, but the spacing angle is not limited, and the near-root bodies can be spaced 90°, 100°, 135°, 180°, etc. The invention can also include the case where three or four root base bodies are positioned and installed on the rod 1 while sliding along the sliding guide rail 160.

[0154] According to one embodiment of the present invention, by fixing two or more rootstocks 204, 205 to the fixing surface 150 of the support frame 101, that is, to the outside of the utility pole 1 and fixing them on the same plane, it is advantageous to further strengthen the support of the utility pole 1 by means of two or more rootstocks 205, 206, while facilitating the sliding positioning of each rootstock 205, 206 with a support frame 101.

[0155] According to the third embodiment of the present invention described above, a method for reinforcing the support of the utility pole 1 under the utility pole 1 using the utility pole clamping device 13 is described.

[0156] First, dig a pit at the location where you want to hang utility pole 1, and then erect utility pole 1.

[0157] According to one implementation plan, an operator (user) digs a pit (pole hole), for example using a auger crane, to a depth close to the height of the utility pole 1 to be erected on the installation ground (g). The pit (pole hole) H can be dug using a rotary excavator.

[0158] At this point, the area where the pole clamping device 13 will be installed will be additionally excavated to ensure sufficient installation space (near-ground installation space) for the pole clamping device 13. The arrangement of the near-ground installation space allows the pole clamping device 13 to be installed above the depth of the pole hole but below the ground level. In one embodiment, the width of the pole installation space is equivalent to the full width of the pole body 203. However, in some cases, the width of the pole installation space can be slightly wider to facilitate the installation of the pole clamping device 13.

[0159] Next, insert the lower end of utility pole 1 into the dug hole (pole hole), and utility pole 1 will stand upright. At this point, the lower end of utility pole 1 can be temporarily embedded in the ground where it will be installed.

[0160] Here, pole 1 is equipped with pole clamping device 13.

[0161] According to one embodiment, a support frame 101 is installed along the outer perimeter of the lower end of the upright utility pole 1. The lower end of the support frame 101 is provided with a flange 170, and the flange 170 has multiple (e.g., four) bolt holes 121, 122, 123, and 124, so that the support frame 101 can be fixedly installed on the outer perimeter of the utility pole 1 by bolts.

[0162] Here, the support frame 101 is installed on the lower outer circumference of the utility pole 1, and the utility pole 1 can be erected in the utility pole hole.

[0163] Next, the rootstock 203 is fixed to the fixing surface 150 of the support frame 101. Here, a circumferential sliding guide rail 160 is provided on the mounting surface 150. After the rootstock 201 is installed, the sliding parts 250 and 260 on the lower surface of the mounting surface 150 of the support frame 101 can slide along the sliding guide rail 160.

[0164] Then, when the sliding parts 250 and 260 of the root body 203 slide along the sliding guide rail 160, the installation position of the root body 203 is selected to be perpendicular to the outer circumference of the utility pole 1, i.e., a predetermined angle position (e.g., 60°).

[0165] Once the installation location is selected, the rootstock 203 will be fixed to the utility pole 1 via the joint 301.

[0166] For example, the operator can securely fasten the pole body 203 to the pole 1 by inserting the threaded portions 331 and 332 at both ends into the bolts formed on the pole body 203 through the gaps 251 and 252, while pushing the bent portion of the U-bolt 330 to wrap around the pole 1 from the outside, and then tightening the nuts 341 and 342.

[0167] Here, if the pole clamping device 13 includes more than one rooting body, another rooting body, such as the second rooting body 205, is placed on the stationary surface of the support frame 101, and the sliding parts 250, 260 on the lower surface are slid along the sliding guide rail 160 to select the installation position of the second rooting body 205 relative to the outer periphery of the pole 1 at different working positions (such as 180°).

[0168] Then, in the same manner, the second body 205 is fixedly attached to the utility pole 1 using the joint 301.

[0169] Once the clamping bodies 200 and 205 are fixedly connected to the utility pole 1, backfilling can be carried out to bury the utility pole clamping device 13 underground, thus completing the construction of the utility pole clamping device 13.

[0170] Figure 20 This is a schematic diagram illustrating an example of applying the extended deformation fixing member of the second embodiment to a utility pole clamping device according to a third embodiment of the present invention. See Figure 20 In the pole clamping device 14 according to one embodiment, a through hole 233 is formed at a first position of the clamping body 203 as described in the third embodiment, along the vertical direction of the pole 1. Here, the through hole 133 may be formed on one end side of the clamping body 203 to prevent interference with the support frame 101. However, as an example, the through hole may be formed to continuously pass through the clamping body 203 and the support frame 101. In another example, multiple through holes may be formed on the support frame 101 at predetermined intervals.

[0171] After the clamping body 203 is placed on the support surface 150 of the support frame 101 as described above, it is positioned and installed at a first position relative to the outer periphery of the utility pole 1 by sliding along the sliding guide 160, and is fixedly connected to the utility pole 1 by the connecting part 301. If necessary, another pole body, such as the second pole body 205, can also be positioned and further fixedly connected to the pole 1 in the same manner.

[0172] Once the clamping body 203 is fixedly connected to the utility pole 1, backfilling is required to bury the clamping device 14. In this case, the backfill height should reach the height of the upper surface of the clamping body 203.

[0173] Next, the drill bit is inserted into the through hole 233 of the clamping body 203 and drilled to form a hole of a predetermined depth in the lower ground. In the drilled hole, the expansion deformation fixing member 500 is inserted through the through hole 233, and the expansion manipulator 530 is inserted into the main body 510 of the expansion deformation fixing member 500 to realize the expansion deformation of the deformation part 520, as described in the second embodiment.

[0174] On the other hand, when multiple through holes are formed at predetermined intervals on the support frame 101, the clamping body 203 will be fixed on the support frame 1201. After selecting the installation position, the clamping body 203 will be fixedly connected to the utility pole 1 through the joint 301.

[0175] Then, after a hole is formed in the lower ground through each through hole of the support frame 101, the expansion deformation fixing member 500 is inserted, and the deformation member 520 is expanded and deformed using the expansion manipulator 530 as described above.
