Description

  The present invention relates to a vertically long member hanging tool for moving to a predetermined place in a state where a plurality of vertically long members are suspended.

  Examples of the vertically long member include a protective tube for protecting an electric wire, and a protective tube housing bag that can accommodate and carry a plurality of the protective tubes together has been proposed. The protective tube storage bag includes a cylindrical upper part, a bottomed cylindrical lower part, a plurality of ropes connecting the lower part of the upper part and the upper part of the lower part in the vertical direction, and the upper part And a rope for suspension connected to the upper end portion (see, for example, Patent Document 1).

  Explaining how to use the above-mentioned protective tube storage bag, first, a plurality of protective tubes are stored vertically in the protective tube storage bag, and a work table (operator gets on board) connected to the tip of the boom of an aerial work platform. Hang a rope for hanging on a hook provided in a basket that can be raised at a high altitude and work at a high place. Subsequently, the work table is raised and moved to the vicinity of the electric wire. Thereafter, the protective tube accommodated in the protective tube storage bag is lifted upward so that the lower end of the protective tube is positioned higher than the upper end of the lower portion. From this state, the protective tube is tilted so that the lower end of the protective tube is disengaged from the lower side. From this tilted state, the protective tube is lowered downward, and the protective tube is removed from the upper side portion, thereby being removed from the storage bag.

  Since the protective tube is hung outside a work table located at a high place, the operation of taking out the protective tube in this situation becomes complicated. For this reason, during the take-out operation of the protective tube, the hand may slip from the protective tube, causing the protective tube to fall to the ground. Therefore, the protective tube must be taken out carefully, which is a very time-consuming operation and there is room for improvement.

  Then, this invention makes it a subject to provide the vertical member hanging tool which can take out a vertical member easily and rapidly.

  A vertically long member suspending tool according to the present invention includes a plurality of holders for holding a vertically long member and a connecting member for connecting the plurality of holders, and each of the holders is inserted from one end side to sandwich the vertically long member. The pair of holding portions hold the vertical member by holding the vertical member by moving the vertical member in the radial direction and entering between the holding portions from one end side. Further, the vertically long member is configured to be able to be released by being moved to one end side.

  According to such a configuration, the longitudinal member can be sandwiched and held by the pair of sandwiching portions only by allowing the longitudinal member to enter between the sandwiching portions from one end side. Further, by simply moving the held vertically long member to one end side, the holding is released and the vertically long member can be quickly taken out. When the vertically long member is a particularly long protective tube, the protective tube is not lifted when it is taken out, so that the protective tube can be easily and quickly taken out without contacting the electric wire.

  Further, in the vertically long member hanging tool according to the present invention, the plurality of holders are rotatably connected to the connecting member, and each of the holders is connected to the connecting member in a state where the vertically long member is not held. On the other hand, a vertically long member is inserted into the pair of holding portions of the holder rotated from one end of the holder so that one end faces downward and the other end rotates in the horizontal direction. It may be configured to be held above the center portion.

  According to such a configuration, in the state where the holder does not hold the vertically long member, the vertical member hanging tool becomes compact due to its own weight in a hanging posture in which one end faces downward with respect to the annular member. This is advantageous in terms of transportation and storage of the hanger. Further, by holding the vertically long member inserted from one end side into the pair of holding portions of the holder rotated so that one end thereof is directed in the horizontal direction, the center of gravity of the vertically long member is increased. Can be located on the lower side. Thereby, downward gravity acts on the vertically long member, and the vertically long member can maintain the posture along the substantially vertical direction. On the other hand, when the vertically long member is held slightly below the central portion in the length direction, the vertically long member collapses and spreads in the lateral direction. Problems such as difficulty in moving occur.

  Further, in the vertically long member hanging tool according to the present invention, the connecting member includes an annular member to which the plurality of holders are connected, and a string-like body to be connected at two locations in the circumferential direction of the annular member. It may be a configuration.

  According to such a configuration, since the string-like body is provided, the vertically long member hanging tool can be suspended only by hooking the string-like body on the hook.

  As described above, according to the present invention, it is possible to take out a vertically long member by providing a plurality of holders that can be held and held by being moved from one end side to the one end side. It is possible to provide a vertically long member suspension that can be easily and quickly performed.

  A vertically long member hanging tool according to the present invention will be described with reference to the drawings. 1 and 2 show a vertically long member hanging tool 1 in a state where a protective tube 4 attached to an electric wire is held, and FIG. 3 shows a vertically long member hanging member in a state where the protective tube 4 is not held. The tool 1 is shown, and FIG. 4 shows the vertically long member suspending tool 1 in a state where only one protective tube 4 is held. FIG. 5 shows the vertically long member suspending tool 1 in a state in which the bird harm prevention pipe 7 configured by providing the needle-like body 6 on the outer surface of the protection pipe 4 shown in FIGS. 1 and 2 is mounted. The protective tube 4 and the bird damage prevention tube 7 are vertically long members as used in the present invention. Here, the protective pipe 4 and the bird damage prevention pipe 7 will be described. However, the present invention is not limited to these pipes, and includes a vertically long bar member, a plate member, and the like.

  As shown in FIGS. 1 to 3, the vertically long member hanging tool 1 includes a string-like body 2 (shown only in FIG. 1) and an annular member 3 that is connected to and suspended from the string-like body 2. And a plurality of (here, five) holders 5 that are attached to the annular member 3 at intervals in the circumferential direction and hold the protective tube 4.

  As the string-like body 2, a string, a band, a rope, a wire, or the like can be used in addition to the insulation-coated cable. Moreover, as a material of the string-like body 2, a material having stretchability may be used, or a material having no stretchability may be used. Both ends of the string-like body 2 are tied to the annular member 3 at two locations in the circumferential direction of the annular member 3. The string-like body 2 is hooked on a hook F (see FIG. 1) provided on a work table (a basket on which an operator gets on and lifts to work at a high place) connected to the tip of a boom of an aerial work vehicle. belongs to.

  The annular member 3 has a circular cross section and is configured in a ring shape (ring shape), for example, an elastically deformable synthetic resin (which may be configured by a hard synthetic resin or metal material that cannot be deformed). ing.

  The protective tube 4 is expanded by an indirect hot wire tool (not shown), and an electric wire (for example, a high-voltage electric wire) K shown in FIG. 6 is inserted. The protective tube 4 is made of an insulating material such as plastic, and is configured to be expandable by a slit 4M (see FIGS. 1 and 2) formed over the entire length in the longitudinal direction. The protective tube 1 has a length of 1.5 m, 2 m, 2.5 m, etc., and a length of 3 m or more, for example, 4 m.

  The holder 5 is made of a synthetic resin material having flexibility and has a substantially U-shape. The holder 5 is attached to the annular member 3 so as to be rotatable. Further, the other end of the holder 5 is provided with a pair of arcuate sandwiching portions 5A and 5A that are sandwiched and held by inserting the protective tube 4 from the other end of the holder 5.

  The holding portions 5A and 5A hold the protective tube 4 with a restoring force that is expanded by insertion of the protective tube 4 and returns to the original state. The clamping by the clamping parts 5A and 5A can be released by moving the clamped protective tube 4 to the other end side against the clamping force. In addition, projecting portions 5B and 5B projecting obliquely from the sandwiching portions 5A and 5A so as to increase in distance from the outside in the length direction of the holder 5 are extended. The protective tube 4 can move to the sandwiching portions 5A and 5A by abutting the protective tube 4 on these protruding portions 5B and 5B and expanding the protruding portions 5B and 5B. Note that the protective tube 4 may be moved to the sandwiching portions 5A and 5A after the sandwiching portions 5A and 5A are spread by hand.

  Since one end of the holder 5 is rotatable and the other end is free, when the protective tube 4 is not held, the other end of the holder 5 is suspended by its own weight under its own weight. It becomes a posture (see FIG. 3). Thereby, the vertically long member hanging tool 1 becomes compact, which is advantageous in terms of transportation and storage of the vertically long member hanging tool 1. On the other hand, when the protective tube 4 is held in the holder 5, the protective tube 4 inserted from the other end into the pair of sandwiching portions 5A and 5A of the holder 5 rotated so that the other end faces the horizontal direction. It is held above the central portion in the longitudinal direction (here, the upper end of the protective tube 4). By doing so, the protective tube 4 is maintained in a posture substantially along the vertical direction (see FIGS. 1 and 2, in FIG. 2, the protective tube 4 is in a vertical posture along the vertical direction). On the contrary, when the protective tube 4 is held below the central portion in the longitudinal direction (not shown), the protective tube 4 falls down and the protective tube 4 is laterally moved. The trouble that it spreads and it is difficult to move the vertically long member hanging tool 1 occurs.

  FIG. 4 shows a state in which only one protective tube 4 is held by the holder 5 and the string-like body 2 is hooked on the hook F. In this way, even when only one protective tube 4 is held by the holder 5, the protective tube 4 does not turn sideways, and maintains an inclined posture in which the lower side approaches the annular member 3 side.

  In FIG. 5, the bird damage prevention pipe 7 provided with a large number of needle-like bodies 6 protruding in the radial direction from the outer surface of the protection pipe 4 and preventing the birds from catching on the protection pipe 4 is provided. 5 shows the case where it is held. Each needle-like body 6 is provided with a large number of needles 6A configured in a cross shape projecting radially outward in an arc-like fitting member 6B that is fitted and fixed to the outer surface of the protective tube 4. It is configured.

  When a plurality of bird damage prevention pipes 7 provided with the needle-like body 6 are accommodated in, for example, a bag, the needle-like shape of the bird damage prevention pipe 7 on the side to be taken out to the needle-like body 6 of the adjacent bird damage prevention pipe 7 The body 6 must move from above while colliding. For this reason, there is a disadvantage in that the movement resistance is large and the taking time is long. On the other hand, in the present invention, the bird harm prevention pipe 7 provided with the needle-like body 6 is held in the holder 5 of the vertically long member suspending tool 1, so that it is not from above but from the side (the radial direction of the annular body). ) By moving to the outside, the needle-like body 6 does not collide, and the bird damage prevention pipe 7 provided with the needle-like body 6 can be easily taken out from the radial direction. The taken-out bird harm prevention pipe 7 is attached to the electric wire K as shown in FIG.

  The procedure from holding the protective tube 4 to the vertically long member suspending tool 1 until mounting the protective tube 4 to the electric wire K will be described. As shown in FIG. 3, the vertically long member suspending tool 1 is in a hanging posture in which all (here, five) holders 5 have the other end facing downward due to their own weight. From this state, the string-like body 2 is hooked on the hook F shown in FIG. Subsequently, the other end of the holder 5 is rotated so that the other end thereof is directed horizontally, and then the protective tube 4 is pushed from the other end of the holder 5, whereby the pair of holding portions 5 </ b> A. Hold at 5A. After all the protective tubes 4 are held in the holder 5, the work table is moved up and down to the vicinity of the electric wire K where the protective tubes 4 are to be mounted. After the movement, the protective tube 4 held by the holder 5 is removed by moving radially outward, and the removed protective tube 4 is attached to the electric wire K. Subsequently, the protective tube 4 held by the holder 5 is removed by moving it radially outward, and all the protective tubes 4 are attached to the electric wires K, and the operation is completed.

  In addition, the vertically long member hanging tool according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, the holder 5 is composed of a single U-shaped member. For example, the center of the pair of members in the longitudinal direction is set as a rotation fulcrum part, and the holding part is provided on one side of the rotation fulcrum part. You may comprise from the clip which has a holding part in the side. Then, an elastic member is provided that can be opened and closed by rotating the holding portion of the pair of members around the rotation fulcrum portion, and is biased in the closing direction of the holding portion. Therefore, the clamping part closed by the elastic member is switched to the open state by operating the grip part to the approach side by hand against the biasing force of the elastic member. The vertically long member is held between the holding portions by sandwiching the vertically long member between the opened holding portions and releasing the hand.

  In the above embodiment, the holder 5 is rotatably connected to the annular member 3 that is a connecting member. However, the holder 5 may be fixed to the annular member 3 so as not to rotate.

  Moreover, in the said embodiment, although the connection member was comprised from the cyclic | annular member 3 and the string-like body 2, you may comprise only from the string-like member which can connect the holder 5. FIG. In this case, when the vertically long member is suspended from the hook, both ends of the string-like member are tied to the hook.

  Moreover, in the said embodiment, although the both ends of the string-like body 2 are respectively tied together in the circumferential direction 2 places of the annular member 3, and are connected with the annular member 3, string-like via a cylindrical connection metal fitting, for example The body 2 may be connected to the annular member 3.

A vertically long member hanging tool according to the present invention includes a plurality of holders for holding a vertically long member to be attached to an electric wire and a connecting member for connecting the plurality of holders, and each of the holders is inserted from one end side. A pair of sandwiching portions that sandwich and hold the longitudinal member, and the pair of sandwiching portions sandwich the longitudinal member by moving the longitudinal member in the radial direction and entering between the sandwiching portions from one end side. Each of the holders is pivotably connected to the connecting member, and each of the holders is connected to the vertically long member. In a state in which no member is held, one end side of the holder is placed on the pair of holding portions of the holder which is in a hanging posture in which one end is directed downward with respect to the connecting member and the one end is turned in the horizontal direction. Enter from An elongated member Mase, characterized in that to hold at the upper side of the central longitudinal portion of it.

According to such a configuration, the longitudinal member can be sandwiched and held by the pair of sandwiching portions only by allowing the longitudinal member to enter between the sandwiching portions from one end side. Further, by simply moving the held vertically long member to one end side, the holding is released and the vertically long member can be quickly taken out. When the vertically long member is a particularly long protective tube, the protective tube is not lifted when it is taken out, so that the protective tube can be easily and quickly taken out without contacting the electric wire.
In addition, when the holder does not hold the vertically long member, the vertical member hanging tool becomes compact by itself due to its own weight in a hanging posture with one end facing downward with respect to the annular member. This is advantageous in terms of transportation and storage. Further, by holding the vertically long member inserted from one end side into the pair of holding portions of the holder rotated so that one end thereof is directed in the horizontal direction, the center of gravity of the vertically long member is increased. Can be located on the lower side. Thereby, downward gravity acts on the vertically long member, and the vertically long member can maintain the posture along the substantially vertical direction. On the other hand, when the vertically long member is held slightly below the central portion in the length direction, the vertically long member collapses and spreads in the lateral direction. Problems such as difficulty in moving occur.
