Description

  The present invention relates to a carrying rack for a construction switch. In particular, the present invention relates to the structure of a transport enclosure for a construction switch that can be taken out from the transport rack when the operation handle disposed on the front surface of the work switch is in the “OFF” state.

  For example, when carrying out electrical work such as replacement of distribution lines, replacement of support insulators, replacement of transformers, etc. on high-voltage distribution lines, temporarily install a construction switch on the power pole in the construction section and install a temporary bypass circuit. Forming. And by this bypass circuit, power transmission is continued even during electrical work.

  By the way, a construction switch is normally provided as a construction equipment in an electric power company or a sales office of a construction company. When there is construction work, a construction switch is mounted on the work vehicle and transported to the construction site. When the construction is completed, the construction switch is mounted on the work vehicle and transported to the sales office.

  In this way, since construction switches are often transported by work vehicles, they must be securely stored in a rigid framed storage rack to prevent damage to the construction switch due to collision or falling. And carrying it.

  However, the conventional construction storage rack for transportation has a problem that it is not easy to attach the construction switch to the transportation rack or to remove the construction switch from the transportation rack. .

  In order to solve such problems, a transport enclosure for a construction switch that is easy to attach a construction switch to a transport rack or to remove a work switch from a transport rack is disclosed. (For example, refer to Patent Document 1).

  The construction storage rack for the construction switch according to Patent Document 1 has a hook-shaped hook on the construction switch side against the latching support part consisting of the recess and insertion hole on the support bracket upper side on the transportation rack side. Since the locking pin can be inserted in a state where the part is hooked and positioned, it is said that the installation work of the construction switch is easy.

  In addition, in the construction storage rack for the construction switch according to Patent Document 1, the locking pin at the rear end of the locking pin is fitted into the locking hole on the side of the support bracket on the transportation storage rack side so that the locking pin is retracted. Since the mounting gap can be secured with certainty, the construction switch can be locked easily.

(Configuration of the enclosure)
Next, the configuration of the storage rack body 1 according to the embodiment will be described. Referring to FIGS. 1 to 5, the storage rack main body 1 has a plurality of equilateral angle irons or unequal angle irons joined together by welding to form a cuboid frame.

  Referring to FIGS. 1 to 5, the storage rack main body 1 includes a pair of front racks 1a and 1b and a pair of rear racks 1c and 1d located at four corners. A bottom rack 1e is fixed to the bottoms of the front racks 1a and 1b and the rear racks 1c and 1d. An upper rack 1f is fixed to the upper parts of the front racks 1a and 1b and the rear racks 1c and 1d. The upper frame 1f is open at the top so that the switch 7 can be taken in and out.

  Referring to FIGS. 1 and 2, the pair of front racks 1a and 1b is provided with a pair of connecting racks 11f and 12f arranged horizontally. The pair of rear racks 1c and 1d are horizontally provided with connecting racks 13f, 14f, and 15f arranged in a horizontal state. The front rack 1a and the rear rack 1c are provided with a plurality of connecting racks 16f arranged horizontally (see FIG. 2 or FIG. 5). Similarly, the front rack 1b and the rear rack 1d are provided with a plurality of connecting racks 17f arranged horizontally (see FIG. 4).

  With reference to FIGS. 1 and 2, the switch 7 can be installed inside the storage rack body 1 from above the storage rack body 1 by grasping the pair of handles 74 a and 74 a. By grasping the pair of handles 74 a and 74 a and pulling up the switch 7, the switch 7 can be taken out from the storage rack main body 1.

  Referring to FIGS. 1 to 5, a pair of angle members 18 f and 18 f are suspended from the connecting frame 12 f arranged at the lower stage. These angle members 18f and 18f rotatably support a rotating shaft 3s constituting a locking means 3 described later. Also, a columnar stay 3st that reinforces the strength against these deformations is attached to the pair of angle members 18f and 18f.

  Referring to FIG. 2 or FIG. 5, the connecting bracket 13f arranged at the upper stage and the connecting rack 14f arranged at the middle stage fix the support metal fitting 410 whose both ends are bent at right angles. A hook-like hook portion 75 can be hooked on the support fitting 410. The upper portion of the support fitting 410 is substantially a hook support portion 41 described later. In addition, a locking portion 42 described later is attached to the lower portion of the support bracket 19f. The detailed description of the hook support portion 41 and the locking portion 42 will be described later.

(Configuration of mounting table)
Next, the configuration of the mounting table 2 according to the embodiment will be described. Referring to FIG. 4, the mounting table 2 has guide holes 2h opened at four corners. The mounting table 2 has a reinforcing channel member 21 attached to the bottom surface (see FIG. 2 or FIG. 5). On the other hand, referring to FIGS. 1 to 5, the storage rack main body 1 includes four guide pins 2 p and four compression coil springs 2 s. The guide pin 2p protrudes from the bottom of the storage rack main body 1. The guide pin 2p is fitted in the guide hole 2h.

  Referring to FIGS. 1 to 5, the compression coil spring 2 s is externally mounted on the guide pin 2 p in a state of being disposed between the bottom surface of the storage rack main body 1 and the mounting table 2. The compression coil spring 2s urges a force that lifts and returns the mounting table 2 against the force by which the mounting table 2 is lowered. That is, when the switch 7 is mounted on the mounting table 2, the mounting table 2 is lowered and the compression coil spring 2s is compressed (see FIG. 1 or FIG. 2). On the other hand, when the switch 7 is pulled up, the compression coil spring 2s is elastically restored, and the mounting table 2 can be raised to the original state (see FIGS. 3 to 5).

(Configuration of locking means)
Next, the structure of the locking means 3 by embodiment is demonstrated. 1 to 5, the locking means 3 includes a rack bar 3r and a pinion 3g which is a spur gear. The locking means 3 includes a rotation shaft 3s and a rotation lever 31. The rack bar 3r is erected from the mounting table 2. The rack bar 3r has a tooth surface 31r on one side surface (see FIG. 2 or FIG. 5).

  1 to 5, the pinion 3g meshes with the tooth surface 31r of the rack bar 3r. The pinion 3g converts the linear motion of the rack bar 3r into rotational motion. The rotation shaft 3s fixes the pinion 3g to one end side. Further, the rotating shaft 3s is rotatably supported by a pair of angle members 18f and 18f.

  Referring to FIG. 3 or FIG. 4, the rotary lever 31 is composed of a cylindrical boss portion 31b and a plate-like lever portion 31t. The boss part 31b is fixed to the base end part of the lever part 31t. The boss portion 31b has a hole that fits in the rotation shaft 3s at the center. The boss part 31b can be fixed to the rotating shaft 3s by fitting the boss part 31b to the rotating shaft 3s and using a set screw or the like.

  Referring to FIG. 2 or FIG. 5, the lever portion 31t extends in the centrifugal direction of the boss portion 31b. The tip of the lever portion 31t is formed in a bowl shape. When the mounting table 2 is lowered from the state shown in FIG. 5, the downward movement of the rack bar 3r is transmitted to the rotating lever 31, and the rotating lever 31 is rotated clockwise. Then, the rotary lever 31 is displaced to a locked state in which the distal end portion of the lever portion 31t is locked to the other end portion 7b side of the operation handle 7h (see FIG. 2).

  When the mounting table 2 is lifted from the state shown in FIG. 2, the lifting movement of the rack bar 3r is transmitted to the rotating lever 31 to rotate the rotating lever 31 counterclockwise. Then, the rotary lever 31 is displaced to an unlocked state in which the tip end of the lever portion 31t is separated from the other end 7b side of the operation handle 7h (see FIG. 5).

  As shown in FIG. 10, in a state where the operation handle 7h is tilted toward the other end 7b, the switch 7 can be stored in the storage rack body 1 without interfering with the tip of the lever portion 31t. 7 can be pulled out of the storage rack main body 1.

  As shown in FIG. 1 or 2, when the operating handle 7h is tilted toward the one end 7a side with the switch 7 placed on the mounting table 2, the tip of the lever 31t is the other end of the operating handle 7h. Since it latches on the 7b side, it becomes difficult to pull out the switch 7 from the storage frame main body 1. When the operation handle 7h is tilted toward the other end 7b, the switch 7 can be pulled out of the storage rack main body 1. That is, it is possible to prevent the switch 7 from being used when the internal switch of the switch body 70 is in the “ON” state.

(Configuration of hook support and locking part)
Next, the structure of the hook support part 41 and the locking part 42 by embodiment is demonstrated. FIG. 6 is an enlarged cross-sectional view taken along the line AA in FIG. 5 and is a state diagram in which the locking pin is made to wait. FIG. 7 is an enlarged cross-sectional view taken along the line AA in FIG. 5 and is a state diagram in which the locking pin is locked to the support protrusion.

  Referring to FIG. 6, the support metal fitting 410 includes a wide main surface plate 411 and a pair of bent pieces 412 and 412 in which both end portions of the main surface plate 411 are bent at a right angle. Referring to FIG. 5, the main face plate 411 has a rectangular cutout portion 41 k cut out at an upper portion thereof. The notch 41k is formed so that its width is slightly larger than the width of the hook 75 (see FIG. 2). The notch portion 41k is substantially the hook support portion 41, and the hook-like hook portion 75 can be hooked on the hook support portion 41. The switch 7 can be positioned with respect to the storage rack main body 1.

  Referring to FIG. 6 or FIG. 7, the locking part 42 includes a J-shaped locking pin 42p and a compression coil spring 42s. The locking portion 42 includes a pair of guide blocks 421 and 421 and a locking block 422. The pair of guide blocks 421 and 421 are fixed to the support fitting 410 at a predetermined interval. Further, the pair of guide blocks 421 and 421 are coaxially opened with a hole 42h in which the long axis of the locking pin 42p is slidable. A similar hole 42h is also coaxially opened in the locking block 422.

  Referring to FIG. 6 or FIG. 7, a clip member 42c is attached to the middle portion of the long axis of the locking pin 42p. The compression coil spring 42s winds the long axis of the locking pin 42p and is disposed between the clip member 42c and one guide block 421. The compression coil spring 42s urges the force of the long-axis tip portion of the locking pin 42p toward the locking block 422.

  Referring to FIG. 6, normally, the locking pin 42p is waiting in a state where the tip of the short axis of the locking pin 42p is locked in the hole opened in the bent piece 412. When the switch 7 is stored in the storage rack main body 1, the pin hole 76h (see FIG. 2) of the support protrusion 76 and the hole 42h (see FIG. 5) of the locking block 422 are made to coincide with each other, and the locking pin 42p is moved approximately 90 degrees. After the rotation, the locking projections 76 and the locking block 422 can be easily connected by releasing the locking pin 42p. That is, the switch 7 can be easily connected to the storage rack body 1.

[Operation of the storage rack for the construction switch]
Next, the operation and effect of the transport storage rack 10 will be described while describing the operation of the transport rack 10 according to the embodiment. Referring to FIG. 1 or FIG. 2, when the switch 7 is stored in the storage rack main body 1, the operation rack 7h is tilted toward the other end 7b as shown in FIG. The switch 7 is inserted into the storage rack main body 1 from above, and the switch 7 is mounted on the mounting table 2.

  When the switch 7 is mounted on the mounting table 2, the mounting table 2 is lowered by the weight of the switch 7. Referring to FIG. 2, in conjunction with the lowering of the mounting table 2, the rotation lever 31 can be directed toward the other end 7 b side of the operation handle 7 h. Next, when the operation handle 7h is tilted toward the one end 7a from the state shown in FIG. 10 (see FIG. 1), the rotation lever 31 makes it difficult to pull the switch 7 from the storage rack body 1 and the operation handle 7h It can be locked to the other end 7b side. In this case, since the operation handle 7h can be operated from between the framed storage rack main body 1, it is convenient.

  When pulling out the switch 7 from the storage rack body 1, the operation handle 7h is tilted toward the other end 7b from the state shown in FIG. In this state, the rotary lever 31 does not interfere with the operation handle 7 h on the other end 7 b side, so that the switch 7 can be pulled out from the storage rack body 1.

  Referring to FIGS. 1 to 7, the storage rack 10 according to the embodiment tilts the operation handle 7h toward the one end 7a so that the internal switch of the switch body 70 is in the “ON” state. Only when the operation handle 7h is tilted to the other end 7b side so that the switch 7 can be transported and the internal switch of the switch body 70 is in the “off” state, the switch 7 is transported to the transport rack 10. Therefore, forgetting to switch the operation handle 7h can be prevented.

  With reference to FIG. 2 or FIG. 5 to FIG. 7, the storage rack 10 according to the embodiment includes a hook support portion 41 that is hooked on a hook-like hook portion 75 provided in the switch body 70, and an open / close state. Since the locking projection 42 provided on the main body 70 is provided with a locking portion 42 having a locking pin 42p that can be locked, the switch 7 can be positioned on the carrying rack 10 and the switch 7 can be transported. It can be easily connected to the storage rack 10.

The carrying rack for the construction switch according to the present invention can be expected to have the following effects.
(1) Since the construction switch can be pulled out from the carrying rack only when it is in the “OFF” state, forgetting to switch the operation handle can be prevented. Human error can be reduced.
(2) Human errors can be reduced and construction can be performed safely.
