JP4630701B2 - Movable inspection table for struts in cableway - Google Patents

Description

  The present invention relates to a check stand which is provided in a support for standing a cable line and supports a rope, and serves as a scaffold during inspection and maintenance.

  A cableway is a facility that bridges a rope between two or more stops, and suspends a carrier on the rope to transport personnel, cargo, etc., and is widely used. In the cableway, in order to support the above-mentioned rope, a pillar is erected in the track, and the rope is supported by the rope receiving device provided on the upper part of this pillar, and the rope is elevated between the stop and the pillar. I have to.

  FIG. 5 and FIG. 6 are a front view and a plan view showing a strut used for a recirculating cableway represented by a generally well-known ski lift. In the figure, a column body 11 is fixedly installed by anchor bolts on a concrete foundation placed in the ground, and a long column arm 12 is crossed over the cableway line above the column body 11. It extends in the direction and is fixed. Although not shown in the drawing, a cable receiving device in which a plurality of receiving rings 13 are rotatably combined is attached to both ends of the support arm 12, and this receiving apparatus or receiving ring 13 is mounted. The rope 14 is supported so as to be movable along the cableway.

A plurality of inspection tables 16 are fixed to the strut arm 12 in the vicinity along the arrangement of the ropes 13 at both ends and between the central portion of the strut body 11 and both ends. An attendant who has climbed the ladder 15 provided in the column main body 11 can inspect and maintain the receiving device and the rope on the inspection table 16. Japanese Patent Application Laid-Open No. H10-228561 discloses a conventional technique for a column check stand in a cableway installed in this way.

  However, since the support table for the support as shown above is fixed to the support arm so that the floor surface is horizontal, it is easy to accumulate snow here if there is snow in the winter. When performing maintenance or maintenance, it was necessary to first remove snow from the inspection table, which was complicated and somewhat dangerous. The present invention has been made in order to solve such a conventional problem, and aims to reduce the labor of snow removal work on an inspection table provided on a cable post and to improve work safety. It is what.

Corresponding to this problem, the present invention is an inspection table formed so as to extend from an arm provided along a slope of the cableway to a support in the cableway so that the floor surface is horizontal. The base is composed of a floor member on which a floor surface is formed and a round steel pipe, and has a first hole drilled in a direction perpendicular to the longitudinal direction at a predetermined position on one end side thereof. An arm member to which the floor member is fixed so that a perforation direction and the floor surface of the floor member are parallel to each other. A mounting bracket made of a round steel pipe having a large diameter is welded and fixed through the arm in the horizontal direction, and the mounting bracket is formed on the upper surface of the portion extending from the arm by the diameter of the arm member. Has a notch cut out with a large width, and the notch At a position near the arm of the mounting bracket has a second hole drilled in a direction perpendicular to the extending direction of the mounting bracket and in the horizontal direction. is inserted into the cutout portion, and wherein by said first hole pin into the second hole is inserted, relative to the arm, the floor surface and the upright state where the floor surface is upright substantially vertical horizontal It is configured to be connected to the sideways state that can be rotated.

  The present invention is configured as described above, so that the floor surface of the inspection table is normally set up in an upright state in the vertical direction, so that there is no snow on the floor surface of the inspection table even if there is a snowfall. By rotating the inspection table to a horizontal position at the time of inspection or maintenance, a platform without snow accumulation is formed, and it is not necessary to remove snow. Therefore, there is an effect that it is possible to quickly start work without performing dangerous snow removal work on the support.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 3 and 4 are a front view and a plan view, respectively, of a cableway post. In FIG. 3, the column main body 21 is erected in a vertical direction on a concrete foundation 20 placed in the ground of the cableway. As shown in FIG. 4, a support arm 22 is fixed to the upper portion of the support body 21 so as to extend in the transverse direction with respect to the cableway. At both ends of the support arm 22, a cable receiving device in which a plurality of cable rings 23 are rotatably arranged and combined is attached, and the cable 24 is supported so as to be movable along the inclination of the cable track. .

  At a position slightly inside from both ends of the support arm 22, an inspection table arm 27 extends and is fixed so as to substantially follow the inclination of the receiving ring 23, and the inspection table arm 27 is inspected outward. A base 26 is rotatably attached. A ladder 25 is fixed from the lower part to the upper part of the column main body 21, and an inspection table 28 is rotatably provided between the upper end of the ladder 25 and the inspection table arm 27.

  Next, details of the mounting portion of the inspection table 26 will be described with reference to FIGS. The inspection table 26 includes a floor member 31 and an arm member 32. The floor member 31 is formed by forming an L-shaped steel frame into a rectangular shape, and an expanded metal is attached to the inner surface to form a floor surface. A hole is drilled, and two L-shaped steels are welded to the upper part so as to be parallel to the hole, and the floor member 31 is placed and fixed on this part.

  On the other hand, a mounting bracket 33 is formed on the inspection table arm. The mounting bracket 33 uses a round steel pipe having a diameter larger than that of the arm member 32, and has one end portion penetrating and fixed to the inspection table arm 27 and the other end portion extending toward the inspection table 26. . The upper surface of the extended portion of the bracket 33 is cut out with a width slightly larger than the diameter of the arm member 32, and a hole is drilled in the horizontal direction at a position near the inspection table arm 27. Yes.

  In such a configuration, the arm member 32 of the inspection table 26 is inserted into the cutout portion of the mounting bracket 33, and the pin 34 is inserted into and connected to the hole of the arm member 32 and the hole of the mounting bracket 33, in this way. The inspection table 26 is rotatably attached. Here, a stopper 35 is fixed to the inner surface of the bracket 33 so that the floor surface of the inspection table 26 becomes horizontal when the inspection table 26 is in the sideways state. When the floor surface of the inspection table 26 is in an upright state, the floor member 31 and the inspection table arm 27 come into contact with each other at a position slightly rotated from the vertical direction toward the inspection table arm 27. By doing in this way, the inspection stand 26 can maintain the standing state by its own weight. In FIG. 1, the state indicated by the solid line is the sideways state, and the state indicated by the broken line is the standing state.

  While the embodiment of the inspection table 26 has been described above, the inspection table 28 can also be configured to rotate between a standing state and a sideways state. In addition, the inspection tables 26 and 28 of the support column configured so as to be rotatable in this way are kept in an upright state at the normal time, so that the snow does not accumulate on the floor member 31 even if there is a snowfall. Sometimes the inspection tables 26 and 28 are brought to the sideways state to form a scaffold without snow accumulation, and since the work for removing snow is unnecessary, the work can be started immediately and safely.
