Description

Power transmission and distribution cable support device for power conduits that facilitates maintenance of power transmission and distribution cables

[0001] The present invention relates to a power transmission and distribution cable support device for a power conduit that facilitates the maintenance of power transmission and distribution cables. More specifically, the invention relates to a power transmission and distribution cable support device for a power conduit that facilitates maintenance by enabling easy separation of a specific cable or a portion of a cable supported by a support device installed inside a power conduit and supporting a plurality of power transmission and distribution cables from adjacent cables.

[0002] With the recent acceleration of industrialization, electricity consumption is increasing rapidly. Since this power is supplied from production sites to consumption sites via transmission and distribution cables, these cables are installed by burying them underground to consider various factors, such as urban aesthetics and preventing obstruction to the movement of people and vehicles. They are buried at a certain depth below the surface, and underground power conduits are used to facilitate this process.

[0003]

[0004] To explain this in detail, in order to install power transmission and distribution cables installed underground more safely and securely and to maintain the installation state for a long period, multiple supports are installed at regular intervals on one side of the inner wall of the underground power conduit, and multiple support members are installed at regular intervals above and below each of these supports to install various types of cables, thereby enabling the intended power transmission and distribution cables to be installed safely and in an aligned state inside the underground power conduit.

[0005]

[0006] Many support devices are being developed to enable the stable installation of cables in this manner, and their structures are also being used in various variable ways.

[0007]

[0008] First, if we look at conventional technology,

[0009] Patent No. 10-1571462 (Patent) A support fixing plate for power transmission and distribution cables for power conduits relates to a support fixing plate that prevents cable sagging, wherein a space is formed inside and a slide groove and a rotation groove are formed on one side that penetrate to the outside, wherein a sliding part is formed on one side that is inserted into the space and slides, and a support part is formed on the other side that penetrates the slide groove from the sliding part and extends outwardly, and a support spring is formed between the lower surface of the sliding groove and the lower surface of the support part of the movable member, in a support fixing plate that supports a power transmission and distribution cable, wherein a pulling spring is formed on the upper side of the space formed inside the support fixing plate and the upper side of the sliding part of the movable member are interconnected, and a rotating member is included that rotates by being connected to a rotation shaft formed in the rotation groove of the support fixing plate, wherein one side extends to the space of the support fixing plate so that the lower side of the sliding part can be touched, and the other side extends outward so that the lower side of the support part can be touched. Posting what is happening.

[0010]

[0011] According to the prior art described above, when the cable is positioned on the support fixing plate, the rotating base is configured to support the lower part of the movable member, thereby preventing the movable member on which the cable is seated from sagging.

[0012] However, in a structure where multiple cables are supported side by side on the upper part of the aforementioned movable member, there was no separate component provided for distinguishing specific cables when specific marking or maintenance was required for some of the cables, leading to cumbersome issues such as workers having to share information about certain cables separately. Furthermore, due to the structure in which most cables are arranged and supported side by side, there was an inevitable problem of reduced operational efficiency, such as the narrowing of the working radius caused by other cables placed and supported adjacently during tasks like maintenance of certain cables.

[0013] The present invention was devised to solve the problems of the aforementioned prior art, and focuses on providing a power transmission and distribution cable support device for power conduits that facilitates maintenance of power transmission and distribution cables by forming a horizontally extended shaft portion at the other end of a base portion connected to a support member, and configuring multiple support members along the shaft portion to be able to rotate vertically around the shaft portion, thereby enabling the separation of a specific cable or some cables from adjacent cables for maintenance purposes and improving work efficiency for the specific cable or some cables.

[0014] According to the present invention for achieving the above-mentioned objective, a power transmission and distribution cable support device installed inside a power conduit comprises: a plate-shaped support member installed such that one side portion abuts against the inner side wall of the power conduit; a plurality of base members configured such that one end portion is connected to the other side portion of the support member and is spaced apart at a certain interval along the upper and lower portions of the other side portion; and a shaft portion formed by extending horizontally from the other end portion of the base member and having a plurality of fastening holes formed along the horizontal direction; and a support portion configured such that a plurality of support members are formed along the shaft portion, wherein a through hole into which the shaft portion is inserted is formed from one end portion to the other end portion, a fastening hole is formed from the front portion to the rear portion, an arc-shaped support groove is inserted into the lower portion, and the length from the through hole to the support groove is longer than the length from the through hole to the upper surface, so that each of the support members is configured to rotate vertically around the shaft portion. The technical features include: a fixing member that is inserted into the front fastening hole of each support member configured along the shaft, the fastening hole of the shaft, and the rear fastening hole of the support member, thereby fixing the support member capable of vertical rotation around the shaft to the shaft; and a finishing member connected to the end of the shaft configured with the plurality of support members.

[0015] In addition, the technical feature is that the support member has slide grooves formed at each of the lower ends of the support member, which are inserted from the lower side to the upper side, and a sliding member capable of sliding along the slide groove is configured in each of the slide grooves, and a plurality of fastening grooves are formed at the upper and lower ends of the support member where the slide grooves are formed, which are inserted from the outer side to the inner side, and an insertion hole is formed in the sliding member that communicates with each of the fastening grooves when sliding along the slide grooves, and the sliding member is fixed to the slide groove by a fastening member that is inserted through the insertion hole and fastened to the fastening groove.

[0016] In addition, the technical features include the fact that the support members formed in multiple numbers along the shaft are formed such that their left and right widths become narrower as they go from one side of the shaft adjacent to the base member toward the other side, which is the end of the shaft, and that a phosphorescent part is formed on the outer side of the remaining fastening grooves, excluding the lowest fastening groove among the multiple fastening grooves.

[0017] According to the power transmission and distribution cable support device for a power conduit that facilitates maintenance of power transmission and distribution cables according to the present invention, it maintains the original purpose of being installed inside a power conduit to seat and support power transmission and distribution cables, while at the same time, when it is necessary to indicate specific cables or some cables among the power transmission and distribution cables seated and supported on the upper part of a plurality of support members, or to distinguish them from adjacent cables due to maintenance or other external factors, the support member can be rotated vertically and the specific cables or some cables can be seated in the support groove, thereby allowing them to be positioned at a higher location than other cables that are previously seated on the upper part of the support member, so that a worker can easily recognize the specific cables or some cables, and the worker can smoothly perform tasks such as maintenance of the specific cables or some cables without being constrained by the location of adjacent cables.

[0045]

[0046] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 10 as follows.

[0047]

[0048] First, before describing the present invention, the configuration thereof is examined with reference to FIGS. 1 to 7. In a power transmission and distribution cable support device installed inside a power conduit, the device comprises: a plate-shaped support member (100) installed such that one side portion contacts the inner side wall of the power conduit; a plurality of base members (210) each having one end portion connected to the other side portion of the support member (100) and spaced apart at a certain distance along the upper and lower portions of the other side portion; and a shaft portion (230) formed by extending horizontally from the other end portion of the base member (210) and having a plurality of fastening holes (233) formed along the horizontal direction. A support member (300) is configured such that a plurality of support members (310) are formed along the shaft (230), wherein a through hole (311) into which the shaft member (230) is inserted is formed from one end to the other end, a fastening hole (313) is formed from the front to the rear, an arc-shaped support groove (315) is inserted into the lower portion, and the length from the through hole (311) to the support groove (315) is longer than the length from the through hole (311) to the upper surface, so that each of the support members (310) can rotate vertically around the shaft member (230); It is composed of: a fixing part (400) that is inserted into the front fastening hole (313) of each support member (310) configured along the shaft part (230), the fastening hole (233) of the shaft part (230), and the rear fastening hole (313) of the support member (310), thereby fixing the support member (310) capable of vertical rotation around the shaft part (230) to the shaft part (230); and a finishing part (500) that is connected to the end of the shaft part (230) configured with the plurality of support members (310).

[0049]

[0050] To explain the present invention configured as described above in more detail,

[0051]

[0052] The above support (100) is configured in the shape of a plate so that one side portion is installed to contact the inner side wall of the power conduit.

[0053] Here, it is preferable that the support member (100) be configured such that one side portion contacts the inner side wall of the power conduit and is fixed to the side wall by means of a separate fixing member, etc.

[0054]

[0055] As shown in FIGS. 1 and 2, the base portion (200) is composed of a base member (210) and a shaft portion (230).

[0056] The above base member (210) is configured such that one end is connected to the other side of the support member (100), and multiple base members are configured to be spaced apart at a certain distance along the upper and lower parts of the other side of the support member (100).

[0057]

[0058] The shaft portion (230) is formed by extending horizontally from the other end of the base member (210), and a plurality of fastening holes (233) are formed along the horizontal direction.

[0059]

[0060] As shown in FIG. 2, the support portion (300) is composed of a plurality of support members (310) configured along the shaft portion (230).

[0061] Here, the support member (310) is composed of a through hole (311), a fastening hole (313), and a support groove (315).

[0062]

[0063] The above through hole (311) is formed by penetrating from one end of the support member (310) to the other end so that the shaft portion (230) is inserted therein.

[0064] Here, it is preferable that the shape of the shaft portion (230) and the through hole (311) be formed as a circular shape with the same shape of the side cross-section, so that the support member (310) can rotate vertically with the shaft portion (230) as an axis.

[0065]

[0066] The above fastening hole (313) is formed by penetrating from the front part to the rear part of the support member (310).

[0067] Here, it is preferable that the fastening hole (313) be formed to correspond to the fastening hole (233) so that the fastening hole (313) and the fastening hole (233) of the shaft (230) are connected when the support member (310) is configured along the shaft (230), and this is so that the fixing part (400) to be described below can be inserted into the fastening hole (313) and the fastening hole (233).

[0068]

[0069] The above support groove (315) is formed by being inserted into the lower part of the support member (310) in an arc shape.

[0070] That is, the purpose is to allow the support member (310) to rotate vertically around the shaft (230) so that the lower surface of the support member (310) is positioned at the top and the upper surface is positioned at the bottom, thereby enabling the support groove (315) to accommodate specific cables or some cables.

[0071]

[0072] Additionally, as shown in FIGS. 4 and 5, the support member (310) is formed such that the length (t2) from the through hole (311) to the support groove (315) is longer than the length (t1) from the through hole (311) to the upper surface.

[0073] That is, as illustrated in FIGS. 6 and 7, when the support member (310) rotates vertically around the shaft (230) so that the lower surface of the support member (310) is positioned at the top, the height of the lower surface of the vertically rotated support member (310) and the support groove (315) can be positioned higher than the height of the upper surface of another support member (310) that does not rotate vertically and remains at the top, thereby allowing specific cables or some cables that are seated and supported in the support groove (315) to be positioned at a higher position than adjacent cables, thereby improving the efficiency of the worker's work.

[0074]

[0075] As shown in FIG. 4, the fixing part (400) is inserted into the front fastening hole (313) of each support member (310) configured along the shaft part (230), the fastening hole (233) of the shaft part (230), and the rear fastening hole (313) of the support member (310), thereby fixing the support member (310), which is capable of vertical rotation around the shaft part (230), to the shaft part (230).

[0076] That is, the fixed part (400) is separated from the fastening hole (313) of the support member (310) and the fastening hole (233) of the shaft part (230), so that the worker can vertically rotate the support member (310) so that the lower surface of the support member (310) having the support groove (315) formed therein faces upward as needed, and then insert it into the rear fastening hole (313) of the support member (310), the fastening hole (233) of the shaft part (230), and the front fastening hole (313) of the support member (310) to fix the support member (310) to the shaft part (230).

[0077]

[0078] As shown in FIG. 3, the end portion (500) is connected to the end portion (230) in which the plurality of support members (310) are formed.

[0079] Here, when the end portion (500) is connected to the end of the shaft portion (230), it is preferable that the height of the upper surface of the end portion (500) be positioned higher than the height of the upper surface of the support member (310) in which the support groove (315) is formed at the lower portion, so as to prevent the power transmission cable (c) that is seated and supported on the upper surface of the support member (310) from escaping to the outside.

[0080]

[0081] As shown in FIG. 8, a slide groove (317) and a fastening groove (319) are formed in the support member (310).

[0082]

[0083] The above slide groove (317) is formed by being inserted from the lower side to the upper side at each of the lower ends of the support member (310).

[0084]

[0085] In addition, each of the above slide grooves (317) is configured with a sliding member(s) that can slide along the slide groove (317).

[0086]

[0087] The above fastening groove (319) is formed by being inserted from the outside to the inside at both ends of the support member (310) where the above slide groove (317) is formed, and is formed in multiple numbers with a gap between the upper and lower ends.

[0088]

[0089] Additionally, the sliding member(s) has an insertion hole (s1) formed therein that communicates with each fastening groove (319) when sliding along the slide groove (317), and the sliding member(s) is fixed to the slide groove (317) by a fastening member (b) that is inserted through the insertion hole (s1) and fastened to the fastening groove (319).

[0090]

[0091] That is, the sliding member(s) performs the role of preventing a plurality of power transmission and distribution cables (c) that are seated in the support groove (315) from moving outward when the support member (310) rotates vertically around the shaft portion (230) as an axis and the lower surface of the support member (310) is positioned at the top and the support groove (315) is positioned at the top.

[0092] In other words, when a plurality of power transmission and distribution cables (c) are seated and supported in the support groove (315), the fastening member (b) is separated from the fastening groove (319) and the insertion hole (s1), and after sliding the sliding member (s) upward along the slide groove (317), the fastening member (b) is inserted and fastened into the insertion hole (s1) and the fastening groove (319) communicating with the insertion hole (s1), thereby allowing the sliding member (s) that has moved upward to be fixed.

[0093]

[0094] Meanwhile, as illustrated in FIG. 9, the support members (310) formed in multiple numbers along the shaft (230) are formed such that their left and right widths become narrower as they go from one side of the shaft (230) adjacent to the base member (210) toward the other side, which is the end of the shaft (230).

[0095] That is, the left and right widths of the support member (310) located adjacent to the support member (100) and the base member (210) are formed wider than the left and right widths of the support member (310) located furthest from the base member (210), so that more power transmission cables (c) can be placed and stacked on the upper surface of the support member (310) located adjacent to the support member (100) and the base member (210), thereby enabling stable support of the placed and stacked power transmission cables (c).

[0096]

[0097] In addition, as shown in FIG. 10, a phosphorescent part (319a) is formed on the outer side of the remaining fastening grooves (319), excluding the lowest fastening groove (319) among the plurality of fastening grooves (319).

[0098] That is, the above-mentioned phosphorescent part (319a) facilitates communication between the insertion hole (s1) of the sliding member(s) that slides along the slide groove (317) and the fastening groove (319), thereby allowing the fastening member (b) to be inserted smoothly and enabling the worker to easily find the fastening groove (319) even in a relatively dark working environment.

[0099]

[0100] According to the power transmission and distribution cable support device for a power conduit that facilitates maintenance of power transmission and distribution cables according to the present invention, it maintains the original purpose of being installed inside a power conduit to seat and support power transmission and distribution cables, while at the same time, when it is necessary to indicate specific cables or some cables among the power transmission and distribution cables seated and supported on the upper part of a plurality of support members, or to distinguish them from adjacent cables due to maintenance or other external factors, the support member can be rotated vertically and the specific cables or some cables can be seated in the support groove, thereby allowing them to be positioned at a higher location than other cables that are previously seated on the upper part of the support member, so that a worker can easily recognize the specific cables or some cables, and the worker can smoothly perform tasks such as maintenance of the specific cables or some cables without being constrained by the location of adjacent cables.
