Description

  The present invention relates to a column-top rotary working device for performing work such as overhead wire repair at a position above a vehicle travel path such as a railway track.

In the construction work of railway tracks, a work vehicle such as a railroad vehicle equipped with a work table that can be moved up and down is used as a scaffold. This work vehicle can travel on rails, travels to a position directly below the construction overhead line, and moves the work table on which the worker is placed to a height that reaches the overhead line (for example, Patent Documents). 1).
Japanese Patent Laid-Open No. 9-30316

  However, since the work vehicle used for the overhead line construction travels on the rail and moves to a position directly below the construction overhead line, the construction of the overhead line cannot be performed while the construction on the rail side is being performed. For this reason, conventionally, the rail side construction and the overhead line construction had to be carried out with a time difference.

  SUMMARY OF THE INVENTION Accordingly, the present invention is intended to provide a column-top rotary working device that can efficiently perform work at a position above a vehicle travel path without being affected by work on the vehicle travel path side.

In order to achieve the above object, the present invention provides an apparatus for an operator to perform work above a vehicle travel path, in a vehicle of a ground structure beam straddling the vehicle travel path in the width direction. A suspension column that is detachably attached to a position spaced a set distance in the width direction from the traveling road, and is attached to the suspension column so as to be rotatable in the horizontal direction, at least above the vehicle traveling path and above the vehicle traveling path. And a work table that can be rotationally displaced between the retracted position and the retracted position.
Thereby, the work table is suspended from the beam of the ground structure via the suspension column, and a space is secured between the work table and the vehicle travel path. Further, when the work is not performed at a position above the vehicle travel path, the work table can be rotated to the retracted position.

  Further, at this time, it is desirable to provide a locking mechanism capable of fixing the position of the work table between the upper position of the vehicle traveling path and the retracted position in the column rotating work apparatus. When such a lock mechanism is provided, the work table can be reliably fixed at a fixed position during work and during retraction.

The present invention is particularly effective when the vehicle travel path is a railway track.
When the vehicle travel path is a railroad track, suspension posts are arranged between the railroad tracks so that the work table can be rotationally displaced between the retracted position and the upper positions of the railroad tracks on both sides. May be.
In this case, the work above the adjacent railway track can be switched by rotating the work table while the suspension column is attached to one place on the ground structure.

The work table may be provided with an auxiliary work table that can be advanced and retracted.
In this case, the operator's scaffolding can be expanded further by extending the auxiliary workbench as appropriate as necessary, and the auxiliary workbench can be retracted in situations where the auxiliary workbench is unnecessary. The rotation radius of the work table can be reduced.

Further, the work table may be provided with a gauge for measuring and confirming the work position.
In this case, the distance from the suspension column to the work position can be confirmed by the gauge without returning the work table to the retracted position.

Further, a safety fence that can be adjusted up and down is provided on the work table, and the gauge may be provided on the safety fence.
In this case, the work position can be measured and confirmed using the gauge of the safety fence. Further, by appropriately adjusting the height of the safety fence, for example, the overhead line position on the railway track can be brought close to the measurement object and accurately measured.

According to the present invention, the work platform is suspended from the beam of the ground structure via the suspension column, and a space is secured between the vehicle travel path and the work platform. The work can be performed at an upper position of the vehicle travel path without being received. Therefore, it is possible to perform the work on the vehicle travel path side and the work on the upper side without giving a time difference, so that the work efficiency can be greatly improved.
In addition, when the work is not performed, the workbench can be rotated in the horizontal direction and retracted to a position spaced a set distance from the vehicle travel path in the width direction. As a result, the work using the work table can be temporarily suspended without hindering the running of the vehicle.

Next, an embodiment of the present invention will be described with reference to the drawings.

Pins 13a are pivotally supported. Further, the lower arm 11 extends obliquely downward from the center of the scaffold frame 8 toward the suspension column 5, and the connecting fitting 12 b coupled to the tip of the lower arm 11 is similarly attached to the support piece 13 b on the suspension column 5 side. Pin is pivotally supported. The support pieces 13a and 13b are fixed to the suspension column 5 by clamps 14a and 14b, respectively.

  The workbench 6 is configured to be able to rotate in the range of 90 ° to the left and right around the position perpendicular to the rail 2 at the upper position of the rail 2 (the position shown in FIG. 1). In any orientation rotated by 90 °, the work table 6 comes off the rail 2 and the train track. 1 and 2 show a state in which the work table 6 is at an upper position of the rail 2 in a posture orthogonal to the rail 2, and FIGS. 3 and 4 show the work table 6 in a posture parallel to the rail and the rail 2 and the train. The state in the retreat position out of the orbit is shown.

  A first lock mechanism 15 (see FIG. 2) that locks the rotation of the workbench 6 at a position above the rail 2 (hereinafter referred to as “working position”) between the workbench 6 and the suspension column 5; A second lock mechanism 16 (see FIGS. 3 and 4) for locking the rotation of the work table 6 at the left and right retracted positions is provided.

  The first lock mechanism 15 is provided on the upper surface of the coupling metal 12a so as to be foldable and turnable via a hinge 17, and is suspended from a lock plate 19 having a pair of locking grooves 18 formed on the end face on the turning end side. A pair of lock claws 20 projecting from the support piece 13a on the support column 5 side, and when the work table 6 is in the working position, the lock plate 19 is folded back to form the locking groove 18 as shown in FIG. The lock claw 20 can be fitted from above. The work table 6 is locked at the work position by the engagement of the locking groove 18 and the lock claw 20.

  The second locking mechanism 16 includes a locking protrusion 21 provided on the left and right positions of the support piece 13a on the clamp 14a, and a locking protrusion provided on the upper arm 10 when the work table 6 is in the left and right retracted positions. The locking claw 22 is superposed on the upper and lower surfaces of the 21, and the locking projection 21 and the lock pin 23 (see FIG. 4) inserted into the pin holes 21 a and 22 a provided in the locking claw 22. Yes. The work table 6 is locked at the retracted position by inserting the lock pin 23 into the pin holes 21 a and 22 a of the locking projection 21 and the locking claw 22 when the work table 6 is in either the left or right retracted position.

  Further, as shown in FIG. 5, a flat connection plate 25 is provided on the upper end portion of the suspension column 5 via a plurality of support walls 24, and this connection plate 25 is a flat lower surface of the beam 4 a of the overhead pole 4. To be bolted. In addition, when the beam 4a of the overhead wire 4 is cylindrical, a clamp 26 having a semicircular clamping surface is provided on the upper end portion of the suspension column 5 via the support wall 24 as shown in FIG.

The on-column rotary working device 1 configured as described above is attached to a set position on the beam 4a of the overhead pole 4, and the work table 6 is rotated below the overhead line 3 as shown in FIGS. The position is fixed by the first lock mechanism 15. When carrying out the overhead line construction from this state, an operator rides on the work table 6 and performs the work on the work table 6.
At the time of this overhead wire construction, the work table 6 is suspended from the beam 4 a of the overhead wire pole 4 via the suspension column 5, so that a large space is secured below the work table 6. Therefore, when the work is performed using the work table 6, even if the work on the rail 2 side is performed in parallel, the pole-mounted rotary working device 1 does not interfere with the work on the rail 2 side. .

Further, when the overhead wire construction is temporarily suspended from this state, the lock of the first lock mechanism 15 is released, the work table 6 is rotated to the retracted position, and the work table 6 is moved to the position by the second lock mechanism 16. Fix it. In this state, the work table 6 is out of the rail 2 and the train track. For example, even if the train operation is temporarily resumed in this state, the train operation is kept safe.
In addition, when the train operation is stopped from this state and the overhead wire work is resumed, the second lock mechanism 16 is released and the work table 6 is rotated to the work position. The rotation position is locked by the first lock mechanism 15.

  The work table 6 may be fixed at the work position and the retracted position in addition to the first and second lock mechanisms 15 and 16 described above, and may be fixed to the ground by applying tension with a tow rope or the like. .

FIG. 7 shows another embodiment of the present invention.
In this embodiment, the pole-rotating working device 1 according to the present invention is arranged between a pair of adjacent railroad tracks. Also in this embodiment, the suspension column 5 of the on-column rotary working device 1 is attached to the beam 4a of the overhead pole 4, and the attachment position of the suspension column 4 is the railroad on both sides on the beam 4a. It is set at almost the middle position of the overhead wire arrangement part of the track.

  The basic structure of the column-top rotary working device 1 is substantially the same as that of the above-described embodiment, but the workbench 6 is rotatable between the work position and the retreat position of the railroad tracks on both sides. Also in the case of the pole-rotating work device 1 of this embodiment, although not shown, first and second lock mechanisms 15 and 16 similar to those of the above-described embodiment are provided, and each work position and retreat are provided. The rotational position of the work table 6 can be fixed at the position.

  This embodiment can basically obtain the same operations and effects as those of the above-described embodiment, but the work can be performed while the suspension column 5 of the on-column rotary working device 1 is attached to the beam 4a of the overhead column 4. By simply rotating the platform 6, it can be switched and used as a work platform for two railway tracks. Therefore, the installation of the scaffold can be facilitated, and the overhead line construction of a plurality of railway tracks can be efficiently performed.

  8 to 10 show still another embodiment of the present invention. In the following description, the same parts as those in the above-described embodiment are denoted by the same reference numerals, and the description of the overlapping parts is partially omitted.

  The column-top rotary working device 101 of this embodiment has a basic structure substantially the same as that of the above-described embodiment, and an upper arm 10 and a lower arm 11 are connected to a scaffold frame 8 of a work bench 106, and these arms. The ends of 10 and 11 are rotatably attached to the suspension column 5. A substantially rectangular auxiliary work table 30 is supported between the left and right side frames 8a and 8b of the scaffold frame 8 so as to be movable forward and backward along the extending direction of the side frames 8a and 8b. The front end of the base 106 can be moved forward and backward. Specifically, in the auxiliary work table 30, guide grooves 33 are formed on both side surfaces of the auxiliary scaffold frame 32 that supports the tread plate 31, and the guide rollers 34 project from the side frames 8a and 8b (see FIG. 9). Is supported by the side frames 8a and 8b so as to be able to advance and retreat.

  As shown in FIG. 9, the auxiliary workbench 30 can adjust the advance / retreat position by operating the operation handle 35 disposed between the scaffold frame 8 and the upper arm 10. Specifically, the operation handle 35 is connected to, for example, a rotating shaft of a drum 37 that winds a rope 36 connected to the auxiliary work table 30, and the position of the auxiliary work table 30 is rotated by rotating the drum 37. Can be adjusted.

  In the case of the work table 106 of this embodiment, the safety fence 109 includes a first frame 38 that is supported and coupled to the scaffold frame 8 and a second frame 39 that is supported by the first frame 38 so as to be movable up and down. The relative position of the first frame 38 and the second frame 39 is fixed by a stopper 40. The second frame 39 can freely adjust the elevation height by releasing the stopper 40.

  Further, a gauge 41 is provided on the upper side 39a of the second frame 39, as shown in FIG. 8, and the distance from the suspension column 5 to the overhead line 3 is compared by silently comparing the scale of the gauge 41 and the position of the overhead line. Can be confirmed with sight.

  Although not shown in detail, in the case of this embodiment as well, a locking mechanism similar to that of the above-described embodiment for fixing the rotation position of the work table 106 at the work position and the retracted position is provided. .

  In this on-column rotary working device 101, the work table 106 is suspended from the overhead pole beam via the suspension column 5 in the same manner as in the above-described embodiment. Even if it is rotated, the work table 106 does not hinder the construction on the rail side, and temporary train operation is performed by rotating the work table 106 to the retracted position off the train track. Can be allowed to resume.

  Further, in this column-top rotary working device 101, the operator's platform is expanded by sliding the auxiliary work table 30 forward from the front end of the work table 106 by operating the operation handle 35 on the work table 106. Therefore, the workability of the operator at a position away from the suspension column 5 can be greatly improved. In addition, since the auxiliary workbench 30 can be moved back and forth with respect to the workbench 106, when the workbench 106 is rotated between the upper position of the rail and the retracted position, the auxiliary workbench 30 must be retracted. Thus, the turning radius of the work table 106 can be reduced. Accordingly, the work table 106 can be rotated with a sufficient margin around it, and the work table 106 can be easily rotated.

  Further, in the case of this column-top rotary working device 101, since the gauge 41 for measuring and confirming the installation position of the overhead wire 3 is provided on the upper side 39a of the safety fence 109, the work table 106 is moved to the retracted position. In addition, an operator on the work table 106 can confirm the installation position of the overhead line 3 almost accurately.

  In particular, in this column-top rotary working device 101, since the safety fence 109 is composed of a first frame 38 and a second frame 39 that can be adjusted in relative positions, the stopper 40 is released and the first frame 38 is raised. By doing so, the scale of the gauge 41 can be brought close to the overhead line 3, and the installation position of the overhead line 3 can be measured and confirmed more accurately.

In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in each of the above-described embodiments, the suspension column 5 of the on-column rotary working device 1, 101 is attached to the overhead wire column 4, but the ground structure to which the suspension column 4 is attached is not limited to the overhead wire column 4. As long as it is a ground structure straddling the rail 2 and the overhead wire 3, it may be a bridge bridge.
Moreover, although the case where the on-pillar rotary working device 1 according to the present invention is used for the railway track overhead construction has been described above, the application of the on-column rotary working device 1 according to the present invention is limited to the railway track overhead construction. It can also be used for work above a traveling road such as an automobile road.
