Description

  The present invention relates to a rigid rod reel to be applied to a reel or the like used for accommodating a wire rod (configured with a rigid rod) used in cable overhead wiring work.

  A reel frame made of a bowl-like body is pivotally attached to a base by a support shaft, and a rigid rod housed in a wound shape so as to surround the support shaft is surrounded by the reel frame. A structure having a structure in which the sheet is sequentially fed out is known (for example, Patent Document 1).

JP 2002-17013 (3rd page, FIG. 6)

    Needless to say, the rigid rod tends to become an original shape, that is, a straight line due to the rigidity. However, in the case of the conventional reel, the leading end of the rigid rod is released from the restricted state and is more than the reel frame. If the reel frame is pulled out and left unattended, the reel frame is rotated out of the reel frame due to its rigidity, and therefore, it is necessary to artificially interrupt the reeling out. When a reel is installed and an operator pushes a rigid rod as a wire rod into an aerial installation facility or wiring conduit at a remote work position such as a high place, another worker who is dedicated to rigid rod operation It was necessary to place and stop the reel.

  In addition, in order to prevent the spontaneous extension due to the rigidity of the rigid rod, it is conceivable to install a braking plate by contact friction at the reel center rotation shaft or the extraction position of the rigid rod and continuously add rotation resistance. In this case, the load of the reel rotation operation at the time of feeding and taking-up of the worker increases, which hinders work.

  The present invention has been devised to provide a rigid rod reel that can be automatically uninterrupted without being fed out beyond the reel frame.

  A reel frame made of a bowl-like body is pivotally supported on a base by a support shaft, and a rigid rod housed in a winding shape so as to surround the support shaft is sequentially delivered from the reel frame. In the rigid heel reel, the urns are arranged side by side on the reel frame at an appropriate interval in the rotation direction, and the urns are engaged with each other by an elastic action whose tip is stronger than the rigidity of the rigid heel. The base of the regulating piece to be removed is attached to the base.

  According to the present invention, the rotation of the reel frame due to the rigidity of the rigidity rod is such that the tip of the restriction piece with the base attached to the base engages between the urns constituting the reel frame, and the restriction piece is rigid. Stronger elasticity acts and is prevented, and as a result, the extension of the rigid rod from the reel frame can be restricted. Then, when the rigid rod is pulled in this state and the pulling force works stronger than the elasticity, the tip of the regulating piece repeats the engagement and disengagement between the antipods correspondingly, and the rigid rod is drawn out from the reel frame, and the external force By interrupting the application of, the feeding from the reel frame can be automatically stopped.

  In addition, using this rigid rod reel, for example, when inserting rigid rods at high places such as utility poles for equipment such as spiral hangers, it is necessary to install a reel frame at the high work position. Therefore, it is possible to safely leave the reel frame on the ground of the utility pole.

  In the rigid rod reel A of the embodiment, a support shaft 2 is laterally provided in a cantilever shape on a base 1 constructed by assembling metal rods to each other, and the support shaft 2 is passed through a central shaft tube 3. In this way, the reel frame 4 is pivotally supported by the support shaft 2 and assembled to the base 1.

  The reel 4 has a plurality of slightly curvilinear L-shaped urns 5, which are bent at a bent portion, arranged radially at equal intervals, and the urns 5,. The first to third ring rods 6, 6 ′, 6 having circular shapes at the intermediate portion of the flange portion 5 a and the free end portion of the short rod portion 5 b and the bent flange portion 5 c between the long rod portion 5 a and the short rod portion 5 b, respectively.籠 is arranged and welded to each other, and the casing is welded to the shaft tube 3 at the free end portion of the long rod portion 5a, and has a circular shape when viewed from the front centering on the shaft tube 3. It is constituted by a body, and is pivotally supported as described above on the support shaft 2 of the base 1 in the shaft tube 3 part.

  The reel frame 4 forms a circular gap surrounded by a second ring rod 6 ′ connecting the free ends of the short rod portions 5b,... It is accommodated in a winding shape so as to surround the support shaft 2 to the shaft tube 3 by utilizing rigidity through the accommodation port 8, and the accommodation state is fitted into a support cylinder 9 whose end is fixed to the reel frame 4. The hook 10 provided at the tip is locked to an appropriate urn 5 so that the rigid function is regulated and reliably maintained.

  The base 1 includes bifurcated leg rods 1a and 1a ', a handle rod 1b extending upward from the connecting portion of the leg rods 1a and 1a', and the support extending in the horizontal direction from the connecting portion. It consists of a shaft 2, and restricting pieces 11A, 11B, 11C, 11D are attached to one leg rod 1a.

  The restricting pieces 11A, 11B, 11C, and 11D are attached to the piece 13 of the attachment means 12 and protruded from the attachment means 12. The attachment means 12 includes the first holding piece 14 and the second holding piece 14 provided with the piece 13 protruding. The sandwiching pieces 15 are opposed to each other via the leg rod 1a, and the tip of the butterfly bolt 16 penetrating the sandwiching pieces 14 and 15 is screwed and tightened to the nut member 17 provided on the first sandwiching piece 14 side. The leading ends of the restricting pieces 11A, 11B, 11C, and 11D are engaged with the gaps between the urns 5 and 5 (long rib portions 5a and 5a) of the reel frame 4.

  In addition, the rigidity rod of an Example is applicable as a through-rod described in the said gazette. That is, the hook 10 provided on the rigid rod 7 is connected to the leading member, and the leading member is inserted into a spiral hanger suspended on a hanging line suspended between the utility poles, while using the rigidity of the rigid rod, one of the utility poles. After pushing out to one of the utility poles and feeding it to the other utility pole side, pull the rigid rod from the utility pole side and hold the cable connected to the end of the rigid rod on the spiral hanger between the utility poles It is applied for use in a so-called cable suspension work, and even if the lead material feeding operation is interrupted, the regulation pieces 11A, 11B, 11C, 11D are stronger than the rigidity of the rigid rod 7. The rotation of the reel frame 4 based on the rigidity is restricted by elastic contact with the urn 5, and therefore, the rigidity 杆 is not drawn out from the reel frame 4 except for the application of artificial external force. This is paid out by It is possible to prevent various troubles caused by.

First embodiment

  In the first embodiment shown in FIGS. 1 to 4, the regulating piece 11A is constituted by a leaf spring, and its base is screwed to the piece 13 of the mounting means 12, and the regulating piece 11A has the reel frame 4 attached thereto. When forced (artificially) rotated, the amount (length) of the extent that the urn 5 is in contact, elastically deformed and bent, and instantaneously disengages from between the urns 5 and 5 Are engaged (intervened) with the urns 5 and 5, and the greater (longer) the engagement amount (length), the more force is required. Determined by rigidity.

  That is, when the hook 10 is removed from the urn 5 and left to stand, the rigid rivet 7 tends to be linear due to the rigidity and tries to be fed out from the reel frame 4 while rotating the reel frame 4. The tip of 11A abuts against the urn 5 of the reel frame 4 to regulate the rigidity of the rigid rivet 7, that is, the elasticity of the restricting piece 11A is superior to the rigidity of the rigid rivet 7 and the rotation of the reel frame 4 can be restricted. In this sense, not only the amount of engagement of the restricting piece 11A with the reel frame 4 but also the elastic force of the restricting piece 11A itself can be used as an adjusting means for the rigidity of the rigid rod 7. it can.

Second embodiment

  In the second embodiment shown in FIGS. 5 and 6, the first embodiment uses the leaf spring as a regulation piece 11 </ b> A while the strip spring is in a band shape, whereas the leaf spring is bent into a ring shape and both ends are overlapped with each other. The remaining points are the same as those of the first embodiment except for the differences from the first embodiment.

  Since the circular curved surface comes into contact with the urn 5 and engages / disengages between the urns 5 and 5 in the restricting piece 11B of this embodiment, the engagement / disengagement operation is performed with a relatively weak external force applied to the reel frame 4. Therefore, the present invention is suitable for application to a reel for a rigid rod having a weak rigidity.

Third embodiment

  In the third embodiment shown in FIGS. 7 and 8, the restriction pieces 11A and 11B of the first and second embodiments are used to disengage the tip of the restriction piece 11C between the urns 5 and 5. Unlike the first and second embodiments, the elasticity of 11A and 11B itself is utilized, but the elasticity of the spring 18 that is separate from the restriction piece 11C is utilized.

  That is, the base piece 19b of the support piece 19 provided with a pair of arm pieces 19a and 19a on the distal end side and one end of the pair of springs 18 and 18 are screwed to the piece 13 of the attachment means 12, and the support The side piece 11C ″, 11C of the restriction piece 11C, which is configured by arranging the side piece 11C ″, 11C ″ relative to the rear of the main piece 11C ′ between the arm pieces 19a, 19a of the piece 19. ″ Is interposed, and the arm piece 19 a and the side piece 11 </ b> C ″ are pivotally attached to a support shaft 20 wound around an intermediate portion of the spring 18, and the regulating piece 11 </ b> C is pivotally attached to the support piece 19. The spring having one end fastened to the piece 13 and the other end fastened to the main piece 11C ′ of the restricting piece 11C using a clamping rod 23, with the pivot 20 as a fulcrum. 18 is regulated.

  In the case of this embodiment, when the regulating piece 11C (the main part piece 11C ″) is engaged between the urns 5 and 5, the elasticity of the spring 18 acts even if the rigidity of the rigid ridge 7 is about to work. The rotation of the restricting piece 111 </ b> C around the support shaft 20 by the urn 5 is restricted. As a result, the rotation associated with the rigidity of the rigidity 杆 7 of the reel frame 4 is restricted, and the rigidity 杆 7 from the reel frame 4 is restricted. The payout is interrupted. When the rigid rod 7 is artificially pulled by an external force greater than the elastic force of the spring 18, the urn 5 rotates the regulating piece 11 </ b> C around the support shaft 20 against the bias of the spring 18. Thus, the restriction of the reel frame 4 by the restriction piece 11C is released, and the rigid rod 7 is fed out from the reel frame 4.

Fourth embodiment

  In the fourth embodiment shown in FIGS. 9 and 10, as in the third embodiment, the movement of the urn 5 by the restricting piece 11D, that is, the reel frame 4 using the elasticity of the coil springs 18A and 18A separate from the restricting piece 11D. This is intended to regulate the rotation.

  In the fourth embodiment, the part 13 of the attachment means 12 is formed of a slightly longer rectangular cylinder, and the intermediate part of the restricting piece 11D made of a rectangular cylinder is rotated around the intermediate part of the part 13 by the support shaft 20A. One end of the pair of coil springs 18A, 18A is attached to one end side of the rod-shaped restricting piece 11D via a support 21, and the other ends of the coil springs 18A, 18A are connected to each other. It is configured to be attached to the piece 13 via the supports 21 'and 21' so as to be at an equidistant position from the support shaft 20A, and the remaining points are the same as in the third embodiment.

  When the external force is not applied, the regulating piece 11D of the fourth embodiment maintains a stationary state in a direction orthogonal to the piece 13 by the action of the coil springs 18A and 18A arranged at symmetrical positions. The spring 18A is provided with elasticity that does not expand and contract due to the rigidity of the rigid rod. Therefore, the tip of the restricting piece 11D engaged with the antiques 5 and 5 regulates the movement of the antique 5, and the reel accompanying the movement. The rotation of the frame 4 is also interrupted, and the feeding of the rigid rod 7 from the reel frame 4 is restricted.

  When the rigid rod 7 is pulled in the same manner as in the third embodiment, the pulling force overcomes the elasticity of the coil spring 18A, and the urn 5 presses the regulating piece 11D and rotates around the support shaft 20A. 5 and 5 are disengaged, and the next stage urns 5 and 5 are engaged, and the rigid ledge 7 is fed out from the reel frame 4.

  When the pulling of the rigid rod 7 is interrupted, the coil springs 18A and 18A are restored to their original shape due to their elasticity, and the regulating piece 11D regulates the movement of the regulating rod 5, that is, the reel frame 4, and regulates the feeding of the rigid rod 7.

  In the case of the embodiment, since the coil springs 18A and 18A having the same elastic force are used, they are positioned symmetrically to each other, but when a pair of coil springs 18A and 18A having different elastic forces are used. Should pay attention to the installation position.
