きる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone station wiring board (MD).
F) Electric work table, and generally relates to a support device for the electric work table used on the vertical (V) or horizontal (H) side. 2. Description of the Related Art In general, a work moving ladder is used to perform work related to a telephone station distribution board, but in recent years, an electric work table has been used. However, the electric work table is free to move in the field, causing an accident. The present invention was devised for the purpose of avoiding such a cause as much as possible. Means for Solving the Problems A suspension vehicle is provided at the upper end of a worktable body supported by wheels, and the roller of the suspension vehicle can be freely rolled onto an existing guide rail for a work ladder for a wiring board. The existing guard rail placed on the front of the wiring board is provided with a pair of L-shaped pieces facing in the vertical direction,
A lower guide rail having an inner surface of a tip end piece of the L-shaped piece as a guide surface is attached along the guard rail, and a tip of a projecting member provided at a lower portion of the workbench main body is inserted between the tip end pieces. The lower roller that is housed in the lower guide rail and that rolls in contact with the guide surface is provided at the tip. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an embodiment of a supporting device for an electric work table for a telephone board according to the present invention. FIG. 1 is a schematic front view, FIG. 2 is a schematic side view, FIG. 3 is a cross-sectional view showing the relationship between the lower guide rail and the lower roller, and FIG. 4 is a cross-sectional view showing the relationship between the guide rail and the suspension wheel. In the figure, A is an electric work table, B is a telephone board of a telephone office that uses the electric work table to perform work at a high place, and the electric work table A is attached to a work table body 1 supported by wheels 2. The basket 3 is assembled so that it can be moved up and down, and an operator rides on the basket 3 to control the control panel 4 provided in the basket 3.
The basket 3 is moved up and down as well as moved and stopped in the front-rear direction, and arranged at a desired height position to the wiring board B.
The maintenance inspection work of the right place is performed. 5 is a wiring board B above the wiring board B.
In the existing guide rail provided along the guide rail 5, the guide rail 5 has been used as a work ladder for the past (the electric work table A is an alternative to this work ladder)
The electric work table A is supported on the upper side by assembling a suspension wheel 6 provided at the upper end of the guide rail 5. The suspension wheel 6 is attached to the work table main body 1 on the base side and protrudes from the upper end of the main body 1, and a pair of horizontally rotatable rollers 6a and 6a provided on the upper end side are guided by the guide. A pair of rail pieces 5a, 5a of the rail 5 are mounted so as to roll freely and support the main body 1, that is, the upper side of the electric work table A so as not to fall down. Reference numeral 7 denotes a power supply rail, and reference numeral 8 denotes a power supply trolley combined with the power supply rail 7. Devices such as the control panel 4 mounted on the workbench main body 1 are electrically connected through the power supply rail 7 and the power supply trolley 8. Is supplied and activated. There is also means for connecting the control panel 4 and the like to the power source via a cord without using the power rail 7 and the power trolley 8, but the cord obstructs the movement of the work table A. Should. At the lower part of the workbench main body 1, an arm piece 9 is projected in the direction of the wiring board B, and a long hole 10 is formed in the tip end piece 9a of the arm piece 9 in the vertical direction. 10 guide car 1
The guide wheel 11 is assembled to the arm piece 9 so that the leading end piece 9a is sandwiched between a pair of nuts 12 and 12 that pass through one main body rod 11b and are screwed into a screw portion of the main body rod 11b. The lower roller 11 that can rotate the horizontal axis of the guide wheel 11
a and 11a are assembled to the lower guide rail 13; The lower guide rail 13 is made of a steel material having a cross-sectionally laid groove shape with a pair of L-shaped pieces 13a, 13a opposed in the vertical direction, and a central piece 13b interposed between the L-shaped pieces 13a, 13a. A U-shaped attachment piece 14 is attached at a proper position along the longitudinal direction on the outer surface side of the outer side of the guard rail 15. Attached and arranged along. The L-shaped piece 13a of the lower guide rail 13 is provided.
The inner side surfaces of the tip end pieces 13a ′ and 13a ′ are guided surfaces 13A.
And a pair of the lower rollers 11a and 11a rolling in contact with the guide surface 13A.
As described above, the main shaft 11b is accommodated and disposed in the lower guide rail 13 through a 'and is provided so as to be rotatable in the horizontal axis. In the embodiment, the arm piece 9 and the main body 11b of the guide wheel 11 constitute the projecting member referred to in the “claims”. However, in the practice of the present invention, it is necessary to limit to the structure of the embodiment. Absent. In the case of the embodiment, the guide wheel 11 has a nut 12,
12 is fastened to the arm piece 9, but when the nut 12 is loosened moderately, the arm piece 9 side, that is, the workbench main body 1 side is The length of the long hole 10 becomes free, so the wheel 2
Can absorb the unevenness of the floor on which the vehicle runs. However, if the floor surface is not so uneven, the level of the wheel 2 and the guide rail 13 is adjusted using the long hole 10, the nut 12 is tightened, and the guide wheel 11 is fixed to the arm piece 9. The arm piece 9 and the guide car 1
1, that is, a structure in which the main body 11 b is integrated may be configured as a “protruding member”. Thus, in the vertical direction of the wiring board B, the basket 3 assembled to the workbench main body 1 is moved up and down, stopped at a desired height position, and the work related to the wiring board B is performed. The movement in the direction along the wiring board B supports the electric work table A with the wheels 2, while the upper side is an assembly relationship of the suspension vehicle 6 and the guide rail 5, and the lower side is the guide vehicle 11.
And the lower guide rail 13 are fixedly regulated in the direction along the wiring board B of the work table A, and the control panel 4 moves and stops the work table A and raises and lowers the basket 3. It is done by the operation. Since the present invention is configured as described above,
You can use the existing facilities in the telephone office as they are, and assemble an electric work platform to replace the work ladder.
Since the electric workbench is assembled on the fixed side between the upper side and the lower side, its movement can be moved only in a certain direction without meandering, and therefore the adjustment of the separation width with the wiring board is possible. In addition, since the travel path is constant, it is possible to prevent unnecessary accidents due to indefiniteness.
