Description

Technology Field

[0001] The present invention relates to a vertical cable support bracket, and more specifically, to a vertical cable support bracket installed on a utility pole to provide a place for the head portion of a vertical cable to be installed. Background Technology

[0002] Distribution lines primarily consist of overhead lines, but in urban areas, they are often constructed as underground lines. The connection between these overhead and distribution lines is made by riser cables.

[0003] One end of the riser cable is connected to an underground line, and the other end, that is, the head of the riser cable, is fixedly installed on a support bracket installed on a utility pole.

[0004] Figure 1 illustrates the installation of a riser cable (3). A support bracket (1) is installed on a utility pole, a crossarm (2) is mounted on the end of the support bracket (1), and the head (3a) of the riser cable (3) is installed on the crossarm (2). The head (3a) of the riser cable (3) is connected to an overhead power line (5) by a jumper wire. Additionally, a lightning arrester (4) connected to each overhead power line (5) is installed on the crossarm (2).

[0005] As shown in FIG. 2, the above support member (1) is formed with a structure in which a Y-shaped connecting member (1b) is formed at one end of the main body (1a), a semicircular first band (1c) is formed at the other end, and a semicircular second band (1d) made separately is bolted (1e) to the first band (1c).

[0006] Accordingly, the support bracket (1) can be installed on the utility pole using the first band (1c) and the second band (1d), and the cross arm (2) is mounted on the cross arm coupling member (1b), and the head (3a) of the vertical cable (3) and the lightning arrester (4) are installed on the cross arm (2) as described above.

[0007] However, the above-mentioned conventional support bracket (1) weighs about 20 kg, which is very heavy, making it very difficult for a single worker to operate. In addition, the number of bolts (1e) connecting the first band (1c) and the second band (1d) is four, so the work of attaching and detaching the support bracket (1) is very cumbersome and time-consuming. As such, the conventional support bracket (1) had the problem of reduced work efficiency due to being heavy and having many bolts.

[0008] In addition, the upper surface of the main body (1a) of the support member (1) is a flat surface, and the crossarm connecting member (1b) is in a branched Y shape, and the upper surface of the main body (1a) and the upper surface of the crossarm mounted on the crossarm connecting member (1b) are at almost the same height, making it very easy for birds to build a nest.

[0009] Therefore, there was a problem in that birds or nests came into contact with the live parts, such as the vertical cable (3) and lightning arrester (4), causing malfunctions and power outages in the electrical equipment installed on the utility pole. Prior art literature

[0010] Korean Patent Publication No. 10-2124183 (Published June 17, 2020) The problem to be solved

[0011] Accordingly, the present invention has been devised to solve the aforementioned problems, and aims to provide a vertical cable support bracket that is lightweight and has a reduced number of bolts to improve work efficiency during installation and removal, and prevents the formation of bird nests, thereby preventing electrical equipment failures and power outages. means of solving the problem

[0012] The present invention for achieving the above-mentioned purpose comprises a base that is in close contact with a utility pole and supports a load applied to a support bracket, a pair of bands connected to one side of the base and joined together by a single bolt, a body installed horizontally protruding from the other side of the base, and a cross-linking member installed in a direction perpendicular to the end of the body.

[0013] The above body is made of a lightweight cylindrical pipe.

[0014] The above band has a cylindrical ring portion formed at one end, and the ring portion is rotatably connected to the base via a bolt.

[0015] The above base includes a support portion, which is a curved plate material that adheres to the utility pole, and a cylindrical coupling portion formed on the support portion, and one end of the body is inserted and fixed into the coupling portion.

[0016] A plurality of right-angled triangular reinforcing members are installed between the above-mentioned support member and the connecting member.

[0017] The above band is divided into a fixed part connected to the base and an adjustable part having an end formed for joining with a bolt, the fixed part and the adjustable part overlap, a plurality of connecting holes are formed in the overlapping part, and the fixed part and the adjustable part are connected to each other by inserting a fastening means into the connecting holes that coincide with each other in the fixed part and the adjustable part.

[0018] There is a height difference between the horizontal portion of the above body and the reinforcing member.

[0019] Grounding terminal blocks are installed on both sides of the body of the above-mentioned reinforcing member.

[0020] The above grounding terminal block is a square tube, having a plurality of insertion holes formed on one side into which a grounding wire is inserted, a bolt hole formed on an adjacent side of the one side that corresponds one-to-one with the insertion hole, and a fixing bolt that secures the grounding wire is fastened to the bolt hole.

[0021] A first hole and a second hole are formed at both ends of the body, and a ground-side grounding wire is inserted into the first hole and drawn out through the interior of the body to the second hole, and then connected to one of the two grounding terminal blocks. The two grounding terminal blocks are connected by a connecting wire, and the grounding wires connected to the lightning arresters are connected to the remaining insertion holes in the two grounding terminal blocks, excluding the insertion hole where the ground-side grounding wire and the connecting wire are connected. Effects of the invention

[0022] According to the present invention as described above, the weight of the support member is significantly reduced as it is manufactured using a lightweight pipe.

[0023] The number of bolts connecting the bands of the support bracket is significantly reduced, making the attachment and detachment of the support bracket easier and reducing the time required.

[0024] As described above, the reduction in the weight of the support bracket and the number of bolt work points has the effect of improving the efficiency of the support bracket installation and removal work.

[0025] Meanwhile, the above-mentioned support member has a body composed of a cylindrical lightweight pipe, and the formation of a bird nest is prevented by the existence of a height difference between the body, the crossarm connecting member, and the crossarm connected thereto.

[0026] Therefore, by reducing contact between birds or their nests and the charged parts, it has the effect of preventing electrical equipment failures or power outages. Brief explanation of the drawing

[0028] The present invention is susceptible to various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. The thickness of lines or the size of components, etc., illustrated in the attached drawings may be exaggerated for clarity and convenience of explanation.

[0029] Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these definitions may vary depending on the intent of the user or operator or case law. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0030] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0031] As illustrated in FIGS. 3 and 4, the vertical cable support bracket according to the present invention comprises a band (10) that fixes the support bracket to a utility pole (100), a base (20) that contacts the utility pole (100) to support the load acting on the support bracket and provides a place for installation of the band (10) and the body (30), a body (30) that is installed horizontally on the base (20) to secure a predetermined distance from the utility pole (100), and a cross-linking member (40) mounted in a direction perpendicular to the end of the body (30).

[0032] The above band (10) is manufactured by dividing it into two semicircular parts, left and right. A cylindrical ring portion (11) is formed at one end of each band (10), and the other end is bent to form a flat end portion (12).

[0033] The above ring portion (11) is rotatably connected to the base (20) by fastening a bolt (B1) that penetrates it to the base (20).

[0034] A bolt hole is formed in the end portion (12) so that the ends (12) of the two bands (10) can be joined together by a bolt (B2). Only one bolt hole is formed in the end portion (12), so that the bands (10) can be joined by one bolt (B2). Of course, a nut is used when fastening each of the bolts (B1, B2).

[0035] The above base (20) includes a support portion (21) formed of a curved plate having the same curvature as the outer surface curvature of the utility pole (100) so as to be in close contact with the utility pole (100), and a cylindrical connecting portion (22) protruding from the outer surface of the support portion (21).

[0036] One end of the circular pipe-shaped body (30) is inserted and fixed into the above-mentioned connecting part (22). To this end, the inner diameter of the connecting part (22) is formed to be slightly larger than the outer diameter of the body (30) (about 1 to 1.5 mm).

[0037] The joint (22) and the body (30) can be welded together, and can be connected by a bolt that penetrates the entire joint (22) and the body (30) so that they can be disassembled if necessary.

[0038] In addition, it is preferable that a reinforcing member (23) be formed between the support member (21) and the connecting member (22).

[0039] The above reinforcing member (23) is a plate in the shape of a right triangle connecting the support member (21) and the connecting member (22), and is welded to the support member (21) and the connecting member (22).

[0040] A plurality of reinforcing members (23) may be installed along the outer circumference of the connecting member (22), and in particular, two reinforcing members (23) parallel to each other may be installed on both sides of the connecting member (22), and a bolt (B1) to which the loop member (11) of the band (10) is connected may be installed by forming a bolt hole in each of them.

[0041] Additionally, the coupling part (22) may be installed so as to be positioned toward the upper side of the support part (21). Accordingly, the support part (21) protrudes long toward the lower side of the coupling part (22), thereby securing a sufficient support area at a position lower than the body (30), so that the load acting on the body (30) can be supported more efficiently and stably.

[0042] The above body (30) is a circular lightweight pipe and plays a major role in reducing the total weight of the support bracket. The support bracket according to the present invention has a weight of about 10 kg, which is a significant reduction compared to the weight of a conventional support bracket, which is about 20 kg.

[0043] An L-shaped bar connecting member (40) is welded to the end of the body (30). A bolt hole is formed on the upper surface of the bar connecting member (40) so that a bar (50) of the required length can be connected with a bolt.

[0044] As described above, the vertical cable support bracket according to the present invention is installed on a utility pole (100) using a pair of bands (10), and can normally perform its original function of installing the head of the vertical cable or a lightning arrester on the crossarm (50) provided at the end.

[0045] At this time, the weight of the above-mentioned support bracket is greatly reduced, making it easy for a worker to handle, so that the work can be performed by only one worker.

[0046] In addition, by using only one bolt (B2) to connect the two bands (10), the number of bolt work points is reduced, so the work of installing or removing the support bracket on the utility pole (100) can be carried out very simply and quickly.

[0047] As described above, using the support bracket according to the present invention has the effect of improving work efficiency.

[0048] As shown in FIG. 5, the band (10) may be divided into a fixed part (10a) connected to the base (20) and an adjustable part (10b) where the end (12) is formed.

[0049] The fixed part (10a) and the adjusting part (10b) overlap for a predetermined length, and a plurality of connecting holes (10c) are formed through the overlapped part.

[0050] Therefore, the overlapping length of the fixed part (10a) and the adjusting part (10b) can be adjusted (so that some of the connecting holes (10c) match), and the length of the band (10) can be adjusted by fastening bolts or rivets, etc. to the connecting holes (10c).

[0051] FIG. 6 illustrates an embodiment in which a reinforcing member (40) is not mounted on the body (30), and a reinforcing member (50) is directly mounted on the end of the body (30).

[0052] In this way, if the reinforcing bar (50) is directly mounted on the body (20), the inconvenience of assembling the reinforcing bar (50) to the support bracket at the construction site can be eliminated.

[0053] FIG. 7 is an enlarged view showing the state in which a reinforcing member (40) is installed at the end of the body (30).

[0054] A vertical portion of a reinforcing member (40) is mounted on the end of the body (30), and there is a height difference (h) between the horizontal portion of the reinforcing member (40), that is, between the upper surface and the upper end of the outer surface of the body (30).

[0055] The above height difference (h) is better as it increases, but since the total weight of the support member increases if the vertical portion of the reinforcing member (40) is excessively increased to increase the height difference (h), it is desirable to have an appropriate size.

[0056] The above height difference (h) is intended to prevent linear materials such as branches used by birds when building a nest from being placed between the body (30) and the cross joint (40), thereby making the initial process of building a nest impossible; therefore, it should be approximately 10 to 20 cm.

[0057] As described above, the body (30) is in the shape of a circular pipe, so it is impossible to place a linear material on its upper surface. In addition, due to the height difference (h), a linear material cannot be placed around the intersection point between the body (30) and the reinforcing member (40), making it impossible for birds to build a nest.

[0058] Therefore, by preventing bird nests from forming on the support bracket, damage to electrical equipment or power outages caused by birds or nests coming into contact with nearby live parts can be prevented.

[0059] FIG. 8 illustrates the bottom surface of the connection between the body (30) and the reinforcing member (40).

[0060] A first hole (31) is formed in the body (30) near the base (20), and a second hole (32) is formed near the reinforcing member (40). It is preferable that the first hole (31) and the second hole (32) be formed with a size sufficiently larger than the thickness of the grounding wire so that the grounding wire (70), which will be described later, can be easily inserted and withdrawn.

[0061] In addition, grounding terminal blocks (60) are installed on both sides of the horizontal bottom surface of the reinforcing member (40) relative to the body (30).

[0062] The grounding terminal block (60) is in the shape of a tubular body having a rectangular cross-section, and a plurality of insertion holes (61) are formed on one side, and bolt holes (62) corresponding one-to-one to the insertion holes (61) are formed on a side adjacent to the side where the insertion holes (61) are formed. One of the insertion holes (61) and the corresponding bolt holes (62) are formed on the same line along a direction perpendicular to the length direction of the grounding terminal block (60).

[0063] The upper end of the ground-side grounding wire (70) is inserted into the first hole (31) of the body (30), drawn out through the interior of the body (30) to the second hole (32), and then connected to one of the two grounding terminal blocks (60).

[0064] The end of the grounding wire (70) is inserted into one of the insertion holes (61) of the grounding terminal block (60), and a fixing bolt (63) is inserted into the corresponding bolt hole (62) and tightened. Then, the end of the fixing bolt (63) presses the end of the grounding wire (70) inside the grounding terminal block (60) to fix the grounding wire (70) to the grounding terminal block (60).

[0065] Both grounding terminal blocks (60) are connected by a connecting wire (71). Both ends of the connecting wire (71) are connected and fixed to each of the grounding terminal blocks (60) by a fixing bolt (63).

[0066] As described above, by installing the ground-side grounding wire (70) and the connecting wire (71), the grounding wires (72) connected to the multiple lightning arresters are connected to suitable places among the remaining empty insertion holes (61) of the grounding terminal block (60), thereby grounding the lightning arresters.

[0067] Therefore, not only can the lightning arrester-side grounding wires (72) connected to the multiple lightning arresters installed on the crossarm (50) be neatly arranged without sagging, but also only one ground-side grounding wire (70) from the support bracket runs down the utility pole (100) and connects to the ground, so that the appearance of multiple grounding wires being bundled and fixed on the side of the utility pole (100) as in the past is not visible.

[0068] As described above, by providing a grounding terminal block (60) on the support bracket, the connection and organization of the grounding wire are simplified, thereby increasing the convenience of construction.

[0069] As described above, the present invention has been explained with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the claims below. Explanation of the symbols
