Description

TECHNICAL FIELD

[0001] The present invention relates to a root holder for a power distribution pole, and more particularly, to a root holder for a power distribution pole installed at the bottom of a power distribution pole and buried in the ground to support the power distribution pole. BACKGROUND

[0002] Generally, a power distribution pole is installed at a distance from the ground to provide power from a power substation to a user.

[0003] Such a power distribution pole is generally cylindrical, and a root is provided at the bottom of the power distribution pole to ensure resistance against wind pressure or self-weight.

[0004] In particular, if the object ground on which the power distribution pole is installed is a weak ground, a method of reinforcing the ground by additionally laying a root or pouring concrete of a certain thickness around the power distribution pole has been used to prevent conduction of the power distribution pole due to uneven settlement.

[0005] The root holder has developed from a conventional on-site concrete pouring construction to a precast concrete construction.

[0006] Registered Utility Model No. 20-0303402 is a root holder arranged on one side of a power distribution pole and fixed by a bolt, and Registered Patent No. 10-1277142 is a root holder buried in the ground to support a power distribution pole, wrapped around the outer circumferential surface of the power distribution pole by being combined with each other, formed in a circular plate shape, and arranged between a plurality of support bodies formed in a ring shape on one side and a sheet for combining the plurality of support bodies together as a whole structure surrounding the entire support bodies.

[0007] That is, the conventional root holder can be installed on only one side of the power distribution pole, and the circumferential portion of the power distribution pole is arranged in a circular shape by a bolt fixing method and formed in a combined manner, and these methods can be constructed separately, and thus, in the bolt fixing method, a support base cannot be ensured on the other side of the root holder, and in the circular combined method, the root holder cannot be used if a support is present on one side of the power distribution pole.

[0036] In describing this invention, detailed descriptions of the functions or components of the invention will be omitted if it is believed that such descriptions might unnecessarily obscure the essence of the invention. Furthermore, the terms used below are defined for their functionality according to the invention and may vary depending on the intent or convention of the user or operator. Therefore, their definitions should be based on the entire contents of this listing.

[0037] like Figure 1 and Figure 2 As shown, the support frame for the power distribution pole of the present invention consists of a first support block 10, a second support block 20, and an oil-filled voltmeter 30. Depending on the installation environment of the power pole 1, the first support block 10 can be used to support only half of the perimeter of the power pole 1, or the first and second support blocks 10 and 20 can be used simultaneously to support the entire perimeter of the power pole 1. The specific configuration is as follows.

[0038] The first near-block 10 includes a first near-block body 11 in a hexahedral form, a first support portion 12 supporting a peripheral portion of the pole 1, a second near-block receiving portion 13 into which the second near-block 20 is inserted, and a first oil groove through-hole 14 through which the linear portions 32 of the oil groove 30 are inserted. Figure 4

[0039] The first near-block body 11 is a base structure (concrete, iron, synthetic resin, etc.) supporting the pole 1, and, as viewed in plan, the remaining portions thereof, except for the first support portion 12, can be formed in a straight line, or the other side of the first support portion 12 can be formed in a semicircular shape.

[0040] The first support portion 12 is formed in a semicircular shape on the inner side of the first near-block body 11, supports one half of the peripheral portion of the pole 1, and forms the second near-block receiving portion 13 in the interior thereof, and thus is a structure formed in the upper and lower portions of the second near-block receiving portion 13, respectively.

[0041] The second near-block receiving portion 13 is formed in the interior of the first near-block body 11, receives the second near-block 20, and is open on both sides in the lengthwise direction in order to protrude the second near-block 20 outward, and is arranged along the same line as the upper and lower portions of the first and second near-blocks 10 and 20 in order to support the first and second near-blocks 10 and 20 on the peripheral portion of the pole 1, and thus the second near-block 10 and the second support portion 12 of the second near-block 20 support the pole 1 on the other side of the first near-block 10.

[0042] The second near-block receiving portion 13 is formed in a semicircular shape so as to protrude when the second near-block 20 is rotated.

[0043] The first oil groove through-hole 14 is formed in two places so as to pass through the linear portions 32 of the oil groove 30, one of which is communicated with the second near-block receiving portion 13, and the other of which is a circular hole communicated with the outside.

[0044] In addition, as viewed in plan, the first and second near-blocks 10 and 20 must be formed in semicircular shapes in order to support one half of the circular pole 1, respectively, and, in order to maintain the connection state of the first and second near-blocks 10 and 20, the opposite ends of the first near-block 10 include second near-block connection portions 15.

[0045] The second near-block connection portions 15 are formed in a straight line parallel to each other on the opposite ends of the semicircular first near-block body 11, connect the first near-block 10 on the side of the pole 1, and maintain the connection state of the second near-block 20 by securing a length longer than the semicircular shape so as to overlap the second near-block 20. The connection portions 15 are open on the inner side for the rotation of the semicircular second near-block 20.

[0046] As Figures 1 to 3 ​As shown, the second near-street block 20 includes a second near-street block body 21, a second support portion 22, a second oil valve through hole 23, and an oil valve insertion groove 24.

[0047] The second near-street block body 21, when inserted into the second near-street block receiving portion 13, requires the second support portion 22 to support the surrounding portion of the pole 1 together with the first support portion 12, and in the protruding case, to support the surrounding portion of the other side of the pole 1 on the other side of the first support portion 12.

[0048] The second support portion 22 forms a semicircle on the inner side of the second near-street block body 21, supporting the surrounding portion of the pole 1.

[0049] The second support portion 22 can be handled with sliding or installed with a roller so as to extract the second near-street block 20 with less force inside the first near-street block 10.

[0050] The second oil valve through hole 23 is formed in two places so that the straight portions 32 of the oil valve 30 are respectively penetrated, and regardless of the position (inserted, protruding) of the second near-street block 20, it is communicated with the first oil valve through hole 14.

[0051] The oil valve insertion groove 24 is formed to stably insert the curved portion 31 of the oil valve 30, and is a groove structure that is open to the outside so that the second near-street block 20 can insert the oil valve 30 in the position where the first near-street block 10 protrudes, and both ends are communicated with the second oil valve through hole 24.

[0052] The oil valve insertion groove 23 is opposite to the back of the second support portion 22, that is, there will be the second support portion 22 between the curved portion 31 of the oil valve 30 and the circumferential portion of the pole 1, and thus the position of the oil valve 30 depends on the position of the second near-street block 20.

[0053] The first and second near-street block bodies 11, 21 are formed in a gyroscopic cross section (a cross section that widens from the bottom to the upper portion) to prevent subsidence.

[0054] The oil valve 30 is a product that has a semicircular curved portion 31 and straight portions 32 on both sides, and is fixed to the pole 1 with the first near-street block 10 (the first and second near-street blocks 10, 20).

[0055] Before the oil valve 30 is signed on the first and second near-street blocks 10, 20, a fixing ball 40 can be included to maintain the assembled state of the first and second near-street blocks 10, 20.

[0056] The fixing ball 40 can be clamped to a fixing pin at the overlapping portion (or screw connection) of the first and second near-street block bodies 11, 21, and can prevent the second near-street block 20 from falling out of the second near-street block receiving portion 13, and thus can be applied to only one.

[0057] To configure the second near block 20 from the first near block 10, a fixed ball 40 can be used.

[0058] The upper surface of the first near block 11 passes through the fixed area 40, forming a guide long hole 16 in the same direction as the rotation of the second near block 20, and the second near block 21 forms a circular fixed groove clamped (or screw connected) by the fixed area 40. The fixed groove can be formed more than one along the guide long hole 16, and the ideal position is consistent with the length direction of the two ends of the guide long hole 16 and the center.

[0059] The fixed ball 40 is formed by the size of the head being larger than the width of the guide long hole 16, which can be used as a lever. If the fixed ball 40 is moved along the guide long hole 16, the second near block 20 combined with the fixed ball 40 will move and protrude to the outside of the first near block 10.

[0060] The second near block 20 will protrude the same length as the length of the guide long hole 16, and then the operator can grasp the second near block 20 and rotate after separating the fixed ball 40. Alternatively, the second near block 20 can also be moved by moving the fixed ball 40.

[0061] According to the present application, the installation method of the power distribution pole is as follows:

[0062] Figure 4 The second near block 20 is inserted into the second near block receiving portion 13 of the first near block 10, and the first and second near blocks 10, 20 are fixed by the fixed area 40.

[0063] The first near block 10 in this state is attached to one side of the pole 1, and the other side is signed with an oil bush 30. Specifically, the curved portion 31 of the oil bush 30 is aligned with the circumference of the pole 1, the straight line portion 32 on both sides is inserted into the second oil bush through hole 23 of the second near block 20, and the nut is signed on the other side.

[0064] In this way, the oil bush 30 supports half in the circumference of the pole 1, and the first near block 10 is fixed on the pole 1, and the first support portion 12 of the first near block 10 and the second support portion 22 of the second near block 20 together support half in the circumference of the pole 1.

[0065] On the other hand, in the environment where it is necessary to be set to support the entire circumference of the pole 1, as shown in Figure 5 In the case of inserting the second near block 20, the first near block 10 is attached to one side of the pole 1, so that the first support portion 12 is supported on the circumference of the pole 1, and the second near block 20 is extracted from the first near block 10. The second near block 20 can be withdrawn by rotating the fixed ball 40 and the like, as described above.

[0066] The second proximity block 20 is supported on the periphery of the utility pole 1 by the second support part 22, and on the other side it is supported on the inside of the second proximity block receiving part 13 of the first proximity block 10. When it is rotated and lifted, the first support part 12 remains supported on the periphery of the utility pole 1.

[0067] The second oil through hole 23 of the second near frame pressure block 20 is consistent with the first oil through hole 14 of the first near frame pressure block 10. The curved part 31 of the oil 30 is aligned with the oil insertion groove 24. The straight part 32 is aligned with the second oil through hole 23 and pushed in. The straight part 32 inserts the first through hole 31 of 14 into the protruding nut of the second near frame pressure block 10. The curved part 31 is pressed tightly against the opposite direction.

[0068] Therefore, the first and second support parts 12 and 22 of the first and second near-frame areas 10 and 20 will each support half of the perimeter of the utility pole 1 to support the entire perimeter of the utility pole 1.

[0069] like Figure 6 As shown, it includes wing block 50, which is used to prevent near-shore subsidence, etc.

[0070] The wing blocks 50 are symmetrically protruding from both sides of the first pre-frame block 10 to increase support. However, the present invention specifies that the overall size in the plane changes when the second pre-frame block 20 is inserted into and extended from the first pre-frame block 10. Therefore, the wing blocks 50 should be movable depending on the position of the second pre-frame block 20.

[0071] With the first pre-frame block 10 inserted into the second pre-frame block 20 as the reference position, when the second pre-frame block 20 extends out of the first pre-frame block 10 and is placed on the other side of the front pillar 1, it moves toward the second pre-frame block 20 to reduce eccentricity.

[0072] For example, the moving structure of the wing block 50 includes guide protrusions formed on both sides of the first proximity block 10 along the moving direction of the wing block 50, and guide grooves formed on the side of the wing block 50 for inserting into the guide protrusions, allowing the wing block 50 to move along the guide protrusions. The guide protrusions and guide grooves are designed to prevent the wing block 50 from laterally detaching and moving towards the end (side), thus increasing the cross-sectional area. Furthermore, to keep the wing block 50 fixed at both positions of the first proximity block 10, it is recommended to include fixing openings.

[0073] Additionally, since wing block 50 only supports the first pre-frame block 10, when moving towards the second pre-frame block 20, according to the drawing standard, the left end 20 of wing block 50 lacks a supporting foundation. To solve this problem, the left end of wing block 50 may contain a connecting rod 51 connected to the second pre-frame block 20 (the drawing only shows the lower wing block 50, for example, in a city).

[0074] The connecting rod 51 is inserted into the wing-shaped block 50, and after the second near-frame block 20 is placed on the other side of the front column 1, the connecting rod 51 is advanced toward the second near-frame block 20 and clamped in the connecting groove formed beside the second near-frame block 20.
