Description

Technology Field

[0001] The present invention relates to a fall prevention auxiliary device for a transmission tower climbing tower and a fall prevention assembly including the same. More specifically, the present invention relates to a fall prevention auxiliary device for a transmission tower climbing tower and a fall prevention assembly including the same. Background Technology

[0002] When performing maintenance work on structures such as transmission towers, workers climb the transmission towers wearing ordinary gloves, such as work gloves, and a lanyard device such as a double large-diameter one. That is, the worker climbs the transmission tower by sequentially fastening two lanyards to the stepping-board bolts of the transmission tower with both gloved hands.

[0003] However, when climbing a transmission tower using a lanyard, one must climb by attaching one lanyard to a stepping platform bolt, removing another lanyard from that bolt, and reattaching it to a stepping platform bolt located on the upper side. Consequently, the process of reattaching the removed lanyard to the stepping platform bolt located on the upper side is cumbersome, and there is a risk of the worker falling during this process. In particular, elderly workers aged 60 or older find it difficult to climb transmission towers due to insufficient hand strength, and the risk of falling is even greater.

[0004] When a worker wears a lanyard, they must wear a separate suit that supports their waist and fasten the lanyard connected to the suit with a rope; consequently, there are problems such as increased fatigue and difficulty in performing work due to the load of the suit, rope, and lanyard. In addition, there is an increasing need for enhanced measures to prevent on-site safety accidents following the enforcement of the Serious Accidents Punishment, etc. Act.

[0005] Therefore, there is a need for a device that allows climbing transmission towers in a safe and convenient manner. Prior art literature

However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0026] FIGS. 1 to 4 are perspective views schematically showing the shape of a fall prevention auxiliary device (10) for a transmission tower climbing / descending tower (hereinafter referred to as the fall prevention auxiliary device (10)) according to an embodiment of the present invention. Specifically, FIG. 1 shows the fall prevention auxiliary device (10) supported by a step bolt (B) of a transmission tower (T), and FIGS. 2 to 4 show the configuration of the fall prevention auxiliary device (10). The fall prevention auxiliary device (10) in FIGS. 1 to 4 is merely for illustrating the present invention and is not limited thereto. Accordingly, the shape of the fall prevention auxiliary device (10) can be modified differently.

[0027] As illustrated in FIG. 1, the fall prevention assist device (10) is worn on the user's arm and is formed to catch on the step bolt (B) of the transmission tower (T) when the user climbs onto the step bolt (B) for maintenance work, thereby preventing the user from falling. Meanwhile, the fall prevention assist device (10) can be used to catch on structures such as utility poles or other frame members that the user climbs onto, in addition to the step bolt (B) of the transmission tower (T).

[0028] As illustrated in FIGS. 1 and 2, the fall prevention auxiliary device (10) is formed to be caught on the footrest bolt (B) of the transmission tower (T) to prevent the user from falling, and includes a shoulder attachment unit (100), a hook unit (200), and a band member (300).

[0029] The shoulder attachment unit (100) is fixed to the user's arm. For example, the shoulder attachment unit (100) is fixed to the user's forearm from the elbow to the wrist via a fixing part (120). A hook unit (200) is connected to the shoulder attachment unit (100) via a band member (300). The shoulder attachment unit (100) includes a shoulder attachment part (110) and a fixing part (120).

[0030] The shoulder support (110) is fixed to the user's forearm (hereinafter referred to as the arm) through a fixing part (120). The shoulder support (110) wraps around the user's arm, and its inner surface is formed in a semicircular shape to correspond to the arm. The shoulder support (110) includes a cushion member (111) attached to the outer surface of the shoulder support (110) to mitigate the impact transmitted to the user's arm when the shoulder support (110) strikes the footrest bolt (B).

[0031] The fixing part (120) secures the shoulder part (110) to the user's arm. This fixing part (120) includes a Velcro or snap-fastening strip and is detachably fastened to the shoulder part (110). Additionally, the fixing part (120) is adjustable in length using a buckle. Thus, the shoulder part (110) can be easily worn or removed from the user's arm through the fixing part (120).

[0032] As illustrated in FIGS. 1 and 2, the hook unit (200) is supported to be hooked onto the footrest bolt (B) of the transmission tower (T). The hook unit (200) is formed in a hook shape above the back of the user's hand. The hook unit (200) includes a support frame (210) and a hook frame (220).

[0033] The support frame (210) extends in a direction opposite to the extension direction of the band member (300). That is, the support frame (210) extends in a left-right direction relative to the back of the hand. The support frame (210) is rotatably connected to the band member (300). For example, the support frame (210) is rotatably connected to the band member (300) so as to be inserted into a through hole (310) formed at the end of the band member (300).

[0034] The hook frame (220) is provided in multiple numbers, with one side extending forward from both ends of the support frame (210) and extending toward the other side so as to bend upward toward the back of the user's hand. That is, the hook frame (220) is formed in a hook shape that bends upward toward the back of the hand so as to be caught on the footrest bolt (B) of the transmission tower (T).

[0035] The band member (300) connects the shoulder attachment unit (100) and the hook unit (200). The band member (300) extends from the shoulder attachment unit (100) to a point adjacent to the back of the user's hand. Accordingly, the hook frame (220) connected to the band member (300) extends forward of the user's hand. The lower surface of the band member (300) can be supported to contact the back of the user's hand. A through hole (310) into which a support frame (210) is inserted is formed at the end portion of the band member (300).

[0036] The shoulder attachment unit (100), hook unit (200), and band member (300) of the fall prevention assist device (10) can be custom-manufactured using a 3D printer or the like based on a 3D design so that they can be worn on the arm in a suitable manner, taking into account the user's various physical conditions. The shoulder attachment unit (100), hook unit (200), and band member (300) can be formed from a lightweight material with strong durability.

[0037] As illustrated in FIGS. 2 to 4, the hook frame (220) extends forward from both ends of the support frame (210) and includes a first hook portion (221), a second hook portion (222), and a hinge member (223).

[0038] One side of the first hook portion (221) extends forward from one end of the support frame (210), and extends toward the other side so as to bend upward toward the back of the user's hand.

[0039] The second hook portion (222) extends rearward to form a predetermined curvature with the first hook portion (221). That is, the second hook portion (222) is formed in a hook shape together with the first hook portion (221). The second hook portion (222) is rotatably connected to the first hook portion (221) through a hinge member (223).

[0040] The hinge member (223) includes various members such as pins, bolts, etc., that can rotatably connect the second hook portion (222) to the first hook portion (221).

[0041] The second hook portion (222) is rotatably connected to the first hook portion (221) to form a predetermined curvature defined as a critical curvature with the first hook portion (221). Here, the critical curvature refers to a curvature at which the second hook portion (222) can be formed in a hook shape together with the first hook portion (221) so that the hook frame (220) can be caught on the footrest bolt (B) of the transmission tower (T).

[0042] As illustrated in FIG. 3, the first hook portion (221) has a step (221a) formed thereon to support the second hook portion (222) so as to prevent the second hook portion (222) from rotating beyond a critical curvature when the second hook portion (222) is rotated outwardly to be spaced apart from the first hook portion (221).

[0043] In the second hook portion (222), a stopper (222a) is formed that engages with a step (221a) to prevent rotation beyond a critical curvature when the second hook portion (222) is rotated outwardly to be spaced apart from the first hook portion (221). That is, when the second hook portion (222) is rotated outwardly to be spaced apart from the first hook portion (221), rotation beyond a critical curvature is prevented by the step (221a) and the stopper (222a).

[0044] For example, when a user hooks the hook frame (220) onto the footrest bolt (B) of a transmission tower (T), the second hook portion (222) is prevented from rotating further outward to maintain the hook shape. Therefore, the hook frame (220) can maintain a hook shape when hooked onto the footrest bolt (B). Meanwhile, a separate cover member may be attached to the outer surface of the hook frame (220) to prevent damage to the hook frame (220) when it strikes the footrest bolt (B).

[0045] As illustrated in FIG. 4, when the second hook portion (222) is rotated inward to be adjacent to the first hook portion (221), it is allowed to rotate below a critical curvature. For example, when a user climbs onto the step bolt (B) of a transmission tower (T) and the second hook portion (222) hits the step bolt (B), the second hook portion (222) can be rotated inward so as to be gathered to the first hook portion (221). Thus, the impact when the hook frame (220) hits the step bolt (B) can be mitigated. Meanwhile, when the second hook portion (222) is rotated to be adjacent to or separated from the first hook portion (221), an open space can be formed between the first hook portion (221) and the second hook portion (222) through which the step bolt (B), which is a frame member, is inserted or withdrawn.

[0046] FIG. 5 is a schematic perspective view showing the shape of a fall prevention assist device (10). Specifically, FIG. 5 shows a detection sensor (400) and a communication unit (500) of the fall prevention assist device (10). The fall prevention assist device (10) of FIG. 5 is merely for illustrating the present invention and is not limited thereto. Therefore, it can be modified differently.

[0047] As illustrated in FIG. 5, the fall prevention assist device (10) further includes a detection sensor (400) and a communication unit (500) in addition to the shoulder attachment unit (100), hook unit (200), and band member (300).

[0048] A detection sensor (400) is positioned on the inner surface of the shoulder piece (110) and detects whether the shoulder piece (110) is in contact with the user's arm. That is, if the detection sensor (400) detects that the shoulder piece (110) is in contact with the user's arm, it can be seen that the shoulder piece (110) is properly worn on the user's arm. Conversely, if the detection sensor (400) detects that the shoulder piece (110) is not in contact with the user's arm, it can be seen that the shoulder piece (110) is separated from the user's arm.

[0049] The communication unit (500) remotely transmits to an external communication terminal (M), such as a mobile phone, whether the shoulder attachment part (110) detected by the detection sensor (400) is in contact with or not in contact with the user's arm. That is, another external worker can determine through the communication terminal whether the shoulder attachment part (110) of the shoulder attachment unit (100) is properly worn on the arm of the user who has climbed onto the platform bolt (B) of the transmission tower (T), or whether the shoulder attachment part (110) has been detached from the user's arm. Therefore, it is possible to prevent safety accidents involving the user who has climbed the transmission tower (T) or to take emergency measures in the event of an accident.

[0050] FIG. 6 is a schematic perspective view showing the shape of a fall prevention assembly (1) including a fall prevention auxiliary device (10) according to an embodiment of the present invention. That is, FIG. 5 shows the configuration of the fall prevention auxiliary device (10), chute (20), and rope (30) of the fall prevention assembly (1). The fall prevention assembly (1) of FIG. 6 is merely for illustrating the present invention and is not limited thereto. Therefore, it can be modified differently. Also, in describing FIG. 6, since the configurations of the fall prevention auxiliary device (10) are similar to the structures of FIG. 1 and FIG. 2, the same reference numerals are used for identical parts and detailed descriptions are omitted.

[0051] As illustrated in FIG. 6, the fall prevention assembly (1) is supported to be caught on the structure when a user ascends or descends the structure, and includes a fall prevention aid (10), a chute (20), and a rope (30).

[0052] The fall prevention assist device (10) is provided in multiple units and is fixed to both arms of the user. The configuration of the fall prevention assist device (10) is as described above.

[0053] The suit (20) is worn by the user. This suit (20) includes various safety devices, such as a safety belt, that are worn when the user climbs the transmission tower (T) to perform work.

[0054] The rope (30) connects the fall prevention aid (10) and the chute (20) and is detachably connected to the fall prevention aid (10) and the chute (20). Therefore, when a user climbs the transmission tower (T) to perform work, the fall prevention aid (10) can be detached from the arm for convenience, preventing the fall prevention aid (10) from falling down from the transmission tower (T).

[0055] Although the present invention has been described as previously stated, those skilled in the art will readily understand that various modifications and variations are possible without departing from the concept and scope of the claims set forth below. Explanation of the symbols
