Description

[Technical Field]

[0001] The present invention relates to an improvement in a pole mounting member for attaching electrical equipment to a utility pole. [Background technology]

[0002] In addition to wires and cables, utility poles are equipped with various devices such as insulators, switches, high-voltage cutouts, and transformers. These devices are attached to the poles using cross arms fixed to the poles.

[0003] The cross arm is generally formed in a hollow rectangular shape and is fixed horizontally to a utility pole via a band. Non-Patent Document 1 listed below shows an example of a method for attaching a transformer to a hollow rectangular cross arm. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] Aichi Electric Technical Report No. 40 (2019) p31 Control Power Transformer

[0005] 9 and 10 show a method of attaching an electrical device to an arm according to the method described in Non-Patent Document 1. Fig. 9 is a side view showing the state in which an electrical device 102 is attached to an arm 101, and Fig. 10 is a front view thereof.

[0006] 9 and 10, 103 is a case for an electrical device, and 104 is a lid for the case 103. 105 is a fixed seat fixed to the top of the lid 104 by welding or the like, and 106 is a support rod fixed to the fixed seat 105 by passing its lower end formed in an L-shape from the inside (the center side in FIG. 10) to the outside (the left and right sides in FIG. 10) of the fixed seat 105 and then crimping its tip.

[0007] Reference numeral 107 denotes a pair of clamping members arranged on the arm 101, and reference numeral 108 denotes a nut that is screwed onto the support rod 106 via the clamping members 107, using the threaded portion formed on the upper end of the support rod 106.

[0008] When attaching electrical equipment 102 to arm 101 at a high location on a pole using the method shown in Figures 9 and 10, the clamping member 107 and nut 108 shown in Figures 9 and 10 are removed, and the upper part of fixing seat 105 fixed to the upper part of cover body 104 is placed against the underside of arm 101.

[0009] At this time, as shown in FIG. 9, the arm 101 is positioned between a pair of support rods 106 arranged in the left-right direction, and since the support rods 106 are arranged on the depth side of FIG. 9 (the left-right direction of FIG. 10), the arm 101 passes through between the pair of support rods 106 existing in the left-right direction of FIG. 9 and is in contact with the upper surface of the fixed seat 105 as shown in FIG. 10.

[0010] In this state, the upper ends of the four support rods 106 are inserted into mounting holes (not shown) of the clamping member 107, and then nuts 108 are screwed onto the threaded portions formed on the upper ends of the support rods 106, thereby clamping the cross arm 101 from above and below by the fixing washer 105 and the clamping member 107.

[0011] As a result, the electrical equipment 102 is attached to the cross arm 101 fixed to the utility pole so as not to be able to swing. Summary of the Invention [Problem to be solved by the invention]

[0012] According to the above mounting methods, the electrical equipment 102 can be securely mounted on the cross arm 101 attached to the utility pole, but there are the following problems associated with each method.

[0013] When the electrical device 102 is attached to the arm 101 by the method shown in Figures 9 and 10, as described above, the clamping members 107 and nuts 108 are removed from the four support rods 106 attached to the fixing seat 105 before the electrical device 102 is attached to the arm 101.

[0014] In this state, the upper surface of the fixed seat 105 fixed on the cover 104 of the electrical equipment 102 must be abutted against the lower surface of the arm 101, the clamping member 107 must be placed on the upper surface of the arm 101, and then nuts 108 must be screwed onto each support rod 106 from above the clamping member 107.

[0015] In other words, the work of attaching the electrical device 102 to the cross arm 101 requires carrying the electrical device 102, clamping member 107, and nut 108 to a high position on the utility pole, and then at that high position, performing the work of attaching the electrical device 102 to the cross arm 101, inserting the support rod 106 into an attachment hole (not shown) of the clamping member 107, and screwing the nut 108 onto the support rod 106.

[0016] Handling such a large number of components at a high altitude requires a considerable number of workers, but it is not easy to secure a work area for such a large number of workers at a high altitude.

[0017] Furthermore, components such as clamping member 107 and nut 108 are very easy to drop, and it is extremely dangerous if they are dropped from a high position on the utility pole to the bottom of the pole. Workers who must handle these components separately must exercise more care than usual, which inevitably increases the workload and may result in a loss of worker safety.

[0018] The present invention aims to solve such problems by providing a pole-mounted hanger that can easily work on poles for electrical equipment 102, ensure the safety of workers and those around them, and can be attached to brackets of various sizes. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0030] An embodiment of the present invention will be described below with reference to Figures 1 to 8. Figure 1 is a front view showing a pole mounting hanger 1 of the present invention attached to an electrical device 2. The pole mounting hanger 1 of the present invention is installed at a high position on a utility pole by using a hollow rectangular cross arm, which will be described later, that is fixed horizontally to the utility pole via a band.

[0031] The electric device 2 exemplified in this embodiment is assumed to be, for example, a transformer installed on a pole or a balancer that corrects an imbalance in power load, but is not limited to this.

[0032] The electric device 2 shown in FIG. 1 is generally composed of a case 3 that houses the electric device body inside, and a lid 4 that closes the upper opening of the case 3.

[0033] On the side of the case 3, pole mounting metal fittings 5 ​​for fixing the pole mounting hanger 1 of the present invention to the electrical equipment 2 are attached by welding or the like at upper and lower positions.

[0034] The pole mounting hanger 1 is composed of a lower support bracket 7 and a bolt 8a fixed to the pole mounting bracket 5 by a fixing means 6 consisting of a bolt 6a and a nut 6b, and an upper support bracket 9 connected to the lower support bracket 7 by passing the bolt 8a through the lower support bracket 7 and tightening the nut 8b.

[0035] The lower support bracket 7 has a crank shape consisting of a lower portion 7a and an upper portion 7c extending vertically, and an intermediate portion 7b extending in an inclined direction connecting the lower portion 7a and the upper portion 7c, and the upper support bracket 9 is formed in an approximately crank shape consisting of a lower portion 9a and an upper portion 9c extending vertically, an intermediate portion 9b extending in an inclined direction connecting the lower portion 9a and the upper portion 9c, and an end portion 9d extending horizontally from the upper portion 9c.

[0036] Reference numeral 10 denotes a fixing means for connecting the upper part 7c of the lower support fitting 7 to the upper part 9c of the upper support fitting 9 by means of a bolt 10a provided on the upper part 7c and a nut 10b threadedly engaged therewith.

[0037] Reference numeral 11 denotes a retaining bracket composed of a horizontal portion 11a that abuts against the underside of the end portion 9d of the upper support bracket 9 and a vertical portion 11b that abuts against an arm described below. The lower portion of the vertical portion 11b of the retaining bracket 11 is provided with an L-shaped retaining means 12 whose tip extends from that position to the right in Figure 1.

[0038] Reference numeral 13 denotes a first fixing means for connecting and fixing the end portion 9d of the upper support bracket 9 to the horizontal portion 11a of the holding bracket 11, and is composed of a bolt 13a and a nut 13b. Reference numeral 14 denotes a second fixing means for connecting and fixing the upper portion 9c of the upper support bracket 9 and the upper portion 7c of the lower support bracket 7 to the vertical portion 11b of the holding bracket 11, and is composed of a bolt 14a and a nut 14b.

[0039] Fig. 2 is a plan view showing the pole mounting hanger 1 attached to the electrical equipment 2. As shown in Fig. 2, a first insertion hole 15a is formed in the end 9d of the upper support bracket 9 as a position adjustment means, through which the bolt 13a of the first fixing means 13 is inserted, and the first insertion hole 15a is formed as an elongated hole extending in the longitudinal direction of the end 9d. Note that a first through-hole 15b for inserting the bolt 13a is formed in the horizontal part 11a of the holding bracket 11 shown in Fig. 1 at a position overlapping with the first insertion hole 15a.

[0040] Fig. 3 is a left side view showing the pole mounting hanger 1 attached to the electrical equipment 2. As shown in Fig. 3, a second insertion hole 16a is formed as a position change means from the upper part 7c to the middle part 7b of the lower support bracket 7, through which the bolt 14a of the second fixing means 14 is inserted, and the second insertion hole 16a is formed as an elongated hole extending in the longitudinal direction from the upper part 9c to the middle part 9b. Note that a second through hole 16b having an elongated hole shape is formed from the upper part 9c to the middle part 9b of the upper support bracket 9 shown in Fig. 1, so as to overlap with the second insertion hole 16a, through which the bolt 14a is inserted.

[0041] Reference numeral 17 shown in Figure 3 is a fixing bracket interposed between the head of the bolt 14a of the second fixing means 14 and the upper part 7c of the lower support bracket 7, and has a U-shaped planar shape.As the second fixing means 14 is tightened, its two end portions 17a, 17b are pressed in the direction of fitting into the side of the upper part 7c of the lower support bracket 7, as shown in Figure 2.

[0042] Fig. 4 is a right side view showing the state in which the pole mounting hanger 1 is attached to the electrical equipment 2. Reference numeral 18 shown in Fig. 4 denotes a fixing bracket having a substantially U-shaped planar shape that is interposed between the nut 14b of the second fixing means 14 and the vertical portion 11b when connecting the vertical portion 11b of the holding bracket 11 to the upper portion 9c of the upper support bracket 9 and the upper portion 7c of the lower support bracket 7 with the second fixing means 14.

[0043] The fixing bracket 18 is attached so that its lower portion is positioned above the anti-slip means 12, and by tightening the nut 14b, its both ends 18a, 18b are pressed in a direction to fit onto both side surfaces of the vertical portion 11b of the retaining bracket 11, as shown in Figure 1.

[0044] Reference numeral 19 in Figure 4 denotes an insertion groove drilled upward from the lower end of the widthwise center of the vertical portion 11b of the retaining fitting 11 shown in Figure 1, and the anti-removal means 12 is provided at the bottom of the vertical portion 11b, divided into two parts, left and right, with the center position of the insertion groove 19 open so as not to be blocked.

[0045] Next, the case where the pole mounting hanger 1 configured as described above is used to attach the electrical device 2 to an arm attached to a utility pole will be described with reference to Figures 5 to 8. The electrical device 2 is attached to the arm using an aerial work vehicle or the like at a high position on the utility pole (not shown) by a minimum number of workers.

[0046] Fig. 5 is a front view illustrating a stage prior to mounting the electrical device 2 on the cross arm 20 fixed horizontally to a utility pole via a band or the like. As shown in Fig. 5, the cross arm 20 is generally formed in a hollow rectangular shape.

[0047] 5, before the pole mounting hanger 1 attached to the electrical equipment 2 is attached to the arm 20, the second fixing means 14 is not connected to the retaining bracket 11. Specifically, the second fixing means 14 is in a state where a fixing bracket 17 is attached to the head side of the bolt 14a and a fixing bracket 18 is attached to the nut 14b side, the nut 14b is screwed onto the bolt 14a, and the shaft portion of the bolt 14a is inserted into the second insertion hole 16a of the lower support bracket 7 and the second through hole 16b of the upper support bracket 9.

[0048] In this state, the bolt 14a of the second fixing means 14 is hooked with its shaft portion abutting the lowest part of the second insertion hole 16a and the second through hole 16b, and is tilted so that the nut 14b is on the downward side, with the nut 14b side resting on and abutting the cover body 4.

[0049] In other words, prior to attaching the pole-mounting hanger 1 to the arm 20, the multiple parts constituting the second fixing means 14, such as the bolts 14a, nuts 14b, and fixing brackets 17, 18, are attached to the pole-mounting hanger 1 fixed to the electrical equipment 2, so there is no need to place, hold, or manage these parts at a high location separately from the electrical equipment 2, thereby reducing the burden on the worker.

[0050] Furthermore, there is no risk of these parts falling from a height, ensuring the safety of the surrounding area and reducing the amount of attention required of the worker.

[0051] On the other hand, the first fixing means 13 has the bolt 13a inserted from the underside of the horizontal portion 11a of the retaining bracket 11 through the first insertion hole 15a formed in the end portion 9d of the upper support bracket 9 and the first through hole 15b formed in the horizontal portion 11a, and the nut 13b is screwed onto the tip of the bolt, but the nut 13b is in a state where it is loosened to a certain extent.

[0052] In other words, the retaining bracket 11 is connected to the upper support bracket 9 by the first fixing means 13, but by moving the shaft portion of the bolt 13a of the first fixing means 13 within the first insertion hole, which has a long hole shape, the retaining bracket 11 can be moved horizontally relative to the end 9d of the upper support bracket 9.

[0053] When attaching the pole-mounting hanger 1 with the electrical equipment 2 fixed thereto to the arm 20 from this state, the retaining bracket 11 is moved horizontally relative to the upper support bracket 9 so as to match the width dimension of the arm 20, and then the nut 13b of the first fixing means 13 is tightened onto the bolt 13a to determine the fixing position of the retaining bracket 11.

[0054] Then, the pole mounting hanger 1 is hooked onto the cross arm 20 by hooking the pole mounting hanger 1 from above the cross arm 20 so that the cross arm 20 is positioned between the upper part 9c of the upper support bracket 9 and the vertical part 11b of the retaining bracket 11.

[0055] At this time, since the holding fitting 11 is connected to the end 9d of the upper support fitting 9, there is no need to hold or manage the holding fitting 11 separately from the electrical device 2, which reduces the burden on the worker. In addition, there is no risk of the holding fitting 11 falling from a high place.

[0056] Figure 6 shows the state in which the arm 20 is fitted between the upper part 9c of the upper support bracket 9 and the vertical part 11b of the holding bracket 11. In the state shown in Figure 6, the position of the vertical part 11b of the holding bracket 11 has been adjusted in advance to match the width dimension of the arm 20, as described above, so the arm 20 can be fitted between the upper part 9c of the upper support bracket 9 and the vertical part 11b without any gaps or rattles.

[0057] Next, as shown in Figure 6, the nut 14b side of the second fixing means 14, which is in an inclined state, is lifted, and the shaft portion of the bolt 14a is moved upward within the second insertion hole 16a and the second through hole 16b, which serve as position change means, so that the fixing bracket 18 and the nut 14b are positioned outside the vertical portion 11b of the retaining bracket 11 (to the right side in Figure 7), as shown in Figure 7.

[0058] At this time, the shaft portion of the bolt 14a of the second fixing means 14 passes between the two divided anti-pullout means 12 shown in Figure 4 and is lifted to the top of the insertion groove 19 using the insertion groove 19 in the vertical part 11b of the retaining fitting 11, thereby moving to the horizontal state shown in Figure 7.

[0059] Then, the fixing bracket 18 attached to the bolt 14a passes beside the L-shaped end of the anti-pullout means 12 without coming into contact with it and is lifted to the position shown in Figure 7, and its shaft portion abuts against the underside of the cross arm 20.

[0060] Normally, in this state, the bolt 14a of the second fixing means 14 is positioned at the top of the second insertion hole 16a and the second through hole 16b, but if, for example, the height dimension of the cross arm 20 is greater than that shown in Figure 7, the bolt 14a may be abutted against the underside of the cross arm 20 at a position slightly below the top of the second insertion hole 16a and the second through hole 16b so that the shaft portion is horizontal.

[0061] Once the state shown in Figure 7 is reached, both ends 17a, 17b (see Figure 3) of the fixing bracket 17 on the head side of the bolt 14a of the second fixing means 14 are fitted into the sides of the upper part 7c of the lower support bracket 7, and then the nut 14b is tightened onto the bolt 14a, thereby fitting both ends 18a, 18b (see Figure 4) of the fixing bracket 18 on the nut 14b side into the sides of the vertical part 11b of the retaining bracket 11, thereby transitioning to the state shown in Figure 8.

[0062] In the state shown in Figure 8, the arm 20 is securely clamped around the periphery by the upper part 9c and end part 9d of the upper support bracket 9 and the vertical part 11b of the retaining bracket 11, and the electrical equipment 2 can be fixed so that it cannot swing via the pole-mounting hanger 1.

[0063] In other words, when the pole-mounted hanger 1 is fixed to the arm 20 by the second fixing means 14 using the upper support bracket 9 and the retaining member 11, the pole-mounted hanger 1 can be fixed to the arm 20 without ever removing the fixing bracket 18 or nut 14b from the second fixing means 14, which dramatically reduces the workload on the worker and at the same time ensures safety.

[0064] After the pole-mounting hanger 1 is attached to the arm 20 by the second fixing means 14, the lower part of the fixing bracket 17 of the second fixing means 14 is hooked onto the upper part of the inclined middle part 7b of the lower support bracket 7, thereby reliably preventing the head side of the bolt 14a from sliding down within the second insertion hole 16a and the second through hole 16b.

[0065] Furthermore, the fixing metal fitting 18 on the nut 14b side is caught on the retaining means 12, thereby preventing the nut 14b side from falling out of the insertion groove 19 of the holding metal fitting 11 shown in FIG.

[0066] As described above, the pole mounting hanger 1 of the present invention can be easily and safely attached to the cross arm 20, and the number of workers required can be reduced. As a result, the working space required for workers at high altitudes can be reduced.

[0067] Furthermore, the state in which the pole mounting hanger 1 is attached to the arm 20 is reliably maintained by the presence of the intermediate portion 7b of the lower support bracket 7 and the anti-detachment means 12, so that the fixed state to the arm 20 is firm.

[0068] As described above, according to the pole mounting hanger of the present invention, the second fixing means can be hooked into the second insertion hole and the second through hole of the support bracket before being hung on the cross arm, so there is no need to hold or manage the second fixing means separately from the pole mounting hanger at high altitudes on the pole, thereby reducing the workload and improving workability for workers.

[0069] Furthermore, when using the second fixing means to clamp and fix the arm with the support bracket and retaining bracket, there is no need to remove the nuts that make up the second fixing means, insert bolts, or fit the nuts, which dramatically simplifies the work and prevents components and parts such as bolts and nuts from falling, reducing the amount of attention required from the worker and ensuring safety in the surrounding area.

[0070] Furthermore, the support bracket is provided with a position adjustment means, which allows it to be attached to arm brackets of various sizes, eliminating the need to prepare different pole hangers for each size of arm bracket.

[0071] Furthermore, after the second fixing means clamps the arm between the support bracket and the retaining bracket, the presence of the intermediate portion of the fixing bracket and the support bracket and the anti-slip means reliably prevents the second fixing means from slipping down the second insertion hole and second through hole or from falling out of the insertion groove of the retaining bracket.

[0072] In this embodiment, the pole mounting hanger 1 is explained as being composed of a lower support bracket 7 and an upper support bracket 9, both of which are connected by upper and lower fixing means, but it goes without saying that the pole mounting hanger 1 of the present invention does not have to be composed of two support brackets, and may be composed of a single support bracket in the shape shown in Figure 1.

[0073] Furthermore, the equipment to be mounted on a pole is not necessarily limited to electrical equipment, and it is obvious that it can be used for any equipment that needs to be mounted on a pole, and as long as it is attached via an arm, it does not necessarily have to be installed on a utility pole. [Industrial Applicability]
