A sheet member that is disposed between adjacent bone members with respect to the circumferential direction of the rail and that can be expanded between the bone members ;
The rail is configured to be attached to the column via an U-shaped mounting jig that is fitted from above into a horizontal plate that is a structural material of the column through an opening that opens downward. ,
The mounting jig is a distance that can adjust a horizontal distance between the rail and the inner peripheral surface of the rail.
It is attached to the rail through a separation adjusting means,
Further, the distance adjusting means is a simple tent characterized in that the distance adjusting means is constituted by a lever fixed to the rail and the mounting jig through hinge portions at both ends .

The second aspect of the present invention is:

  According to the present invention, the seat member can be extended through the bone member by attaching the rail to the support and moving the moving pieces along the rail. Moreover, a series of operations can be performed easily and quickly.

  As a result, a work space that does not get wet in the rain can be formed below the sheet member, and a predetermined work can be performed in this work space without getting wet in the rain. Therefore, it is possible to easily and quickly carry out maintenance and inspection of electrical equipment that is particularly unsuitable for adhesion of moisture, for example, maintenance and inspection in the rain on the operation mechanism of the disconnect switch installed outdoors.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a disconnector to which the present embodiment is applied. As shown in the figure, the disconnector 1 has a three-phase base 3 (3a, 3b, 3c) installed in parallel on a support column 2, which is a frame, and a thrust bearing at the center of the upper surface of each base 3. A rotary insulator 5 is vertically and rotatably attached via 4. Further, at both ends of the base 3, a stationary insulator 6 is vertically fixed on the upper surface thereof, and an insulator device 7 is constituted by the rotating insulator 5 and the stationary insulator 6.

  A blade 8 is fixed horizontally to the upper end of the rotary insulator 5 via a support portion 9, and the blade 8 rotates integrally with the rotation of the rotary insulator 5. In addition, a contact terminal 11 having a terminal block 11a to which the overhead wire 10 is connected, a finger contact 11b electrically connected to the terminal block 11a, and the like are provided at the upper end of the fixed insulator 6. The blade 8 is formed of a conductive member, and is provided with a blade contact that constitutes a contact that can contact the finger contact 11b at both ends.

  An operation box 13 that houses an operation mechanism that rotates the operation rod 12 manually or automatically is attached to the support 2. Here, the distal end of the operation rod 12 is connected to a thrust bearing 4 attached to the base 3 via a drive mechanism 14. The thrust bearing 4 connected to the operation rod 12 via the drive mechanism 14 is connected to the thrust bearing 4 of another phase via the operation round bar 15.

  In such a disconnector, the rotational force generated by the operating mechanism is transmitted to the thrust bearing 4 via the operating rod 12 and the drive mechanism 14, and is also transmitted to the thrust bearing 4 of another phase via the operating round bar 15. Since each of the rotors 5 is transmitted to the rotary insulator 5 via the thrust bearings 4, the rotary insulators 5 of the respective phases rotate in synchronization. As a result, both ends of each blade 8 are separated or contacted with the contact terminals 11 and 11 of each phase, thereby opening and closing between the overhead wires 10 and 10. That is, the blades 8 of each phase perform the same opening / closing operation.

  FIG. 2 is a view showing a simple tent used for maintenance / inspection in the rain of the operation mechanism housed in the operation box 13 of the disconnector 1, wherein (a) is a front view thereof, and (b) is a front view thereof. It is a top view. 3A and 3B are diagrams showing each part extracted. FIG. 3A is an enlarged view of a part A in FIG. 2A, and FIG. 3B is an enlarged view of a part B in FIG.

  As shown in these drawings, the simple tent according to this embodiment includes a rail 21, a bone member 22, a seat member 23, and a moving piece 24.

  Here, the rail 21 is a U-shaped member that is formed to be detachable from the support 2 and has a curved portion disposed around the support 2 so as to surround the support 2. Therefore, the rail 21 is disposed so as to surround the column 2 in a horizontal plane by being pushed into the column 2 through the U-shaped opening when mounted on the column 2. The rail 21 is provided with a plurality (five in this embodiment) of moving pieces 24 that move along the rail 21. More specifically, as shown in FIG. 3 (b), the rail 21 is bent at the upper and lower ends of the vertical surface so that the cross-section is L-shaped. Each moving piece 24 moves along the peripheral surface of the rail 21 as a result of its outer peripheral portion coming into contact with the bent portion of the rail 21 to prevent the moving piece 24 from coming out to the outside.

  Further, the mounting of the rail 21 at this time can be performed by one touch through a jig formed of an angle member (the specific structure of the mounting portion of the rail 21 will be described in detail later).

  The same number of bone members 22 as the moving pieces 24 are configured such that their base ends are attached to the moving pieces 24 and project to the opposite side of the support column 2. Here, each bone member 22 is extended obliquely upward from the proximal end portion toward the distal end. That is, the column 2 side is the lowest, and the level is higher toward the outer side (the side opposite to the column 2).

  The sheet member 23 is affixed between the adjacent bone members 22 in the circumferential direction of the rail 21 so that the sheet member 23 can be spread between the bone members 22.

  As a result, the moving piece 24 is moved and moved to one side to bundle the bone members 22 and the sheet member 23 is folded. From this state, the moving piece 24 is moved to the other side to expand the sheet member 23. And a roof can be formed. Moreover, although it is a long thing prescribed | regulated by the length of the bone member 22 when it folds, it becomes a convenient thing for conveyance as a lightweight thing which does not become so bulky.

  When the operation box 13 is opened in the rain and maintenance / inspection of the operation mechanism, which is an internal electrical component, is performed, a predetermined work space is formed using the simple tent according to the present embodiment. Specifically, the rail 21 is first mounted on the support 2. Then, the sheet | seat member 23 is extended through the bone member 22 by moving the moving piece 24 along the rail 21, respectively.

  As a result, as clearly shown in FIG. 2B, a work space that does not get wet with rain can be formed below the sheet member 23, and the operation box 13 is opened in this work space to perform predetermined work. Can be done without getting wet. Here, since the bone member 22 is located at a higher position as the distance from the support column 2 increases, the work space gradually increases toward the outside. This means that the outside ceiling where the worker stands and walks around is high, and good workability can be secured also in this respect.

  The moving piece 24 may be fixed to the bone member 22 through its proximal end, including fixing, and the shape is not particularly limited. It can also be attached to be rotatable. In this case, the moving piece 24 functions as a roller, so that the movement along the rail 21 can be performed extremely smoothly.

  Moreover, in the said embodiment, although the rail 21 was made into the U-shaped member, it is not restricted to this. Of course, it can also be configured in an annular shape. And when it is made cyclic | annular, the sheet | seat member 23 can be extended over the perimeter of the support | pillar 2, and the work space formed can be ensured widely.

  FIG. 4 is an enlarged view showing an extracted rail according to another embodiment of the present invention formed in an annular shape. As shown in the figure, the rail 31 is formed by bringing the opening end of one U-shaped member 31a into contact with the opening end of another U-shaped member 31b and connecting the both ends so as to close the opening end. The whole is formed in an annular shape. That is, one end portions of the U-shaped members 31a and 31b are connected via the hinge portion 32, and the other end portion is connected to the plate member 33 fixed to the other end portion of the U-shaped member 31b by the bolt 34. It has become.

  When the rail 31 is provided, first, the bolt 34 is loosened, and the end of the U-shaped member 31a is opened by rotating the U-shaped member 31b in the clockwise direction in FIG. The U-shaped member 31 a is attached to the column 2 after being pushed around the column 2 through the opening. In this state, the U-shaped member 31b is rotated counterclockwise around the hinge portion as a rotation center, thereby closing the open end of the U-shaped member 31a and connecting the U-shaped members 31a and 31b. As a result, a ring closed by the rail 31 is formed.

  5 is a cross-sectional view taken along the line CC of FIG. 1, FIG. 6 is an enlarged view of a portion D of FIG. 5, (a) is a plan view, and (b) is from the direction E of FIG. FIG. As shown in these drawings, the rail 21 is configured to be attached to the support column 2 via a mounting jig 25 having a U-shaped cross section having an opening 25a that opens downward. That is, it fits into the horizontal plate 2a which is the structural material of the support column 2 from above through the opening 25a of the mounting jig 25.

  Here, as shown in FIG. 6, the rail 21 and the mounting jig 25 are fixed to the inner peripheral surface of the rail 21 and the inner peripheral surface of the mounting jig 25 via hinges 26a and 26b at both ends. The lever 26 is connected. As a result, the distance between the rail 21 and the mounting jig 25 can be adjusted by rotating the lever 26 via the hinge portions 26a and 26b. That is, the lever 26 functions as a distance adjusting unit. As a result, even if the width of the column 2 to which the simple tent is attached changes, this can be flexibly dealt with. That is, if the width is narrowed, the lever 26 is rotated to increase the mounting angle with respect to the rail 21 and the mounting jig 25, and the distance between the rail 21 and the mounting jig 25 is increased. Adjustment may be made so that the distance between the mounting jigs 25, 25 arranged on the left and right is reduced, and in the opposite case, adjustment may be made so as to increase.

  The distance adjusting means need not be limited to the lever 26 as long as the distance in the horizontal direction between the inner peripheral surface of the rail 21 on the column 2 side and the mounting jig 25 can be adjusted.

  Further, in the present embodiment shown in FIG. 5, the base end portions of the belts 27a and 27b are fixed to the front end portion of the rail 21, and the front end portions of both the belts 27a and 27b are connected via, for example, Velcro (registered trademark). By doing so, the fixing of the rail 21 to the support column 2 is made more reliable. In the figure, reference numeral 28 denotes a reinforcing member.

  The present invention can be used in the industrial field where maintenance and inspection of electric power equipment is performed.
