Description

  The present invention relates to an escalator installation method.

  As a conventional escalator installation method, there is a method in which a pulley is attached to the ceiling of the top floor of a building, the lower ends of the suspension wires hung on the escalator are connected to both ends of the escalator, and the escalator is lifted to a predetermined position. (For example, see Patent Document 1)

However, the above conventional method attaches the pulley to the ceiling, so to lift a heavy object such as an escalator, it is necessary to increase the attachment strength of the pulley, and not only the installation work becomes large, but also the pulley. However, there is a problem in that there is no degree of freedom with respect to the deflection of the wire and the wire on the pulling side becomes an obstacle.
Japanese Patent Laid-Open No. 9-2767

  The problem to be solved by the present invention is that the suspension wire can be safely and reliably lifted in any direction, and a heavy object such as an escalator is lifted or installed safely and efficiently. Is to provide an escalator installation method.

In the construction method in which the escalator is lifted by a suspension wire and installed at a predetermined position, the present invention penetrates the wire guide pipes at predetermined positions on at least two upper floors of the escalator to be installed and suspends the wire guide pipes respectively. The upper part of each suspension wire is lifted by the suspension platform through the wire, and the lower ends of these suspension wires are connected to both ends of the escalator, respectively. In addition, the wire guide tube is constituted by a tube passing through the floor and two sets of guide rollers which are installed in the tube and are vertically spaced from each other. Furthermore, the wire guide tube is characterized in that it is composed of a tubular body that penetrates the floor, and a trumpet guard in which an intermediate portion swells inwardly in the tubular body .

  The escalator installation method of the present invention can safely and reliably lift a suspension wire in any direction, and can lift or install a heavy object such as an escalator safely and efficiently. There is an advantage that you can.

  1 to 7 are explanatory diagrams of the construction method of the present invention, where F1 is the first floor, F2 is the second floor, F3 is the third floor, FB is the basement floor, C1 is the first floor ceiling line, and C2 is Second floor ceiling. The building of this embodiment is an atrium that has been removed from the second floor F2 and a part of the first floor ceiling line C1, such as a hotel entrance hall lobby. Escalator E is already installed. The installation method of the present embodiment is to add a new escalator to the existing escalator E and newly install an escalator from the second floor to the third floor.

  FIG. 1 is an explanatory diagram mainly showing a preparation stage of construction. First, the work gantry 1 is lifted below the escalator installation location F3-1 (broken line portion) on the third floor F3. The lifting work is carried out by placing two casters with casters 2 on the left and right at predetermined positions on the third floor F3, lowering the four suspension wires 3 from each suspension base 2 through the third floor F3, and lower ends thereof. Are connected to the left and right corner portions (four locations) of the work gantry 1. Although FIG. 1 shows a state when the lifting is completed, the working gantry 1 placed on the first floor F1 is lifted.

  Reference numeral 4 denotes a pit (indentation) formed on the first floor F1, which is provided adjacent to the pit of the existing escalator E. 4a is also a working gantry. A rail 5 is laid on the pit 4 and the first floor F1. Reference numeral 6 denotes a new escalator, which is carried into the rail 5 while being separated into an upper part 6a and a lower part 6b.

  As shown in FIG. 2, the upper part 6a and the lower part 6b carried into a predetermined lifting position are connected to each other by a hinge part 7 made of a pin or the like so as to be bent. The hinge portion 7 is lifted and supported via a wire 8 by a lifting support member 9 made of H-shaped steel or the like. The lifting support member 9 is installed on the third floor F3 on both sides of the opening. The lifting support member 9 is provided with a winch (not shown) for winding the wire.

  A lifting auxiliary frame 10 is attached to the lower side of the outer end 6a-1 of the upper part 6a. The lifting assist frame 10 extends obliquely downward from the lower side of the outer end 6a-1 of the upper part 6a, and the wire 8 is attached to the tip. The wire 8 passes through a wire guide tube 12 penetrating the third floor F3 and is lifted by a caster-mounted suspension base 11 installed on the third floor F3. Moreover, the lifting auxiliary | assistant frame 10 is provided also under the outer end part 6b-1 of the lower part 6b, and the wire 8 is connected. The wire 8 passes through a wire guide tube 12 penetrating the second floor F2 and is lifted by a caster-mounted suspension base 11 installed on the second floor F2.

  FIG. 3A shows an embodiment of the wire guide tube 12, which is composed of a tube body 12a, a first guide roller 12b, and a second guide roller 12c. The first guide roller 12b and the second guide roller 12c are spaced apart from each other and are orthogonal to each other. FIG. 3B shows another embodiment of the wire guide tube, and a trumpet guard 12d having an intermediate portion swelled inward is provided inside the tube body 12a. With the configuration of these wire guide tubes 12, the upper wire 8 can always maintain the same position and direction regardless of which direction the wire 8 below is deflected. 8 can be rolled up and down stably and reliably. Further, since the wire guide tube 12 can bear the horizontal force accompanying the deflection of the wire when the escalator is lifted, the suspension frame 11 is burdened only by the vertical force, and a light frame structure is sufficient.

  FIG. 4 shows a state where the newly installed escalator 6 is being lifted. The escalator 6 is lifted in a state where the central portion is lowered and the overall length is slightly shortened, and the outer end portion 6a-1 of the upper part 6a is moved to the third floor. While approaching the predetermined installation location of the floor 3F, the outer end 6b-1 of the lower part 6b is brought closer to the predetermined installation location of the second floor.

  Next, as shown in FIG. 5, the upper and lower parts 6 a, 6 b of the newly installed escalator 6 are changed from the bent virtual line state to the straight solid line state (assembled state) while lifting the intermediate hinge portion 7. Finally, the end portions 6a-1 and 6b-1 of the new escalator 6 are fixedly attached to the floor (building frame).

  When the installation work of the new escalator 6 is completed, the installation work of the extension escalator 13 between the first floor and the second floor is subsequently performed as shown in FIG. First, as in the case of the newly established escalator 6, it is carried into the site in the state of parts. The parts of the additional escalator 13 are immediately assembled, and the wires 8 are connected to the upper end portion 13a and the lower end portion 13b, respectively, and are suspended by the suspension base 11 with casters. In particular, the lower end portion 13b is lifted, and the tilting carriage 14 is placed below the lower end portion 13b. A lifting auxiliary frame 10 extends obliquely downward from the lower side of the upper end 13a of the additional escalator 13, and the wire 8 is connected to the tip thereof.

  As shown in FIG. 7, the tilting carriage 14 includes a carriage main body 14b having wheels 14a, a tilting member 14c pivotally mounted on the carriage main body 14b, and a receiver provided on the tilting member 14c. It consists of a frame 14d. Therefore, as shown in FIG. 8, by supporting the lower end portion 13 b of the additional escalator 13 by the tilting carriage 14, the additional escalator 13 can be moved in its longitudinal direction (left and right in FIG. 6) and suspended. By lifting the inserted upper end portion 13a (see FIG. 6), the imaginary line state can be tilted to the solid line state.

  FIG. 9 shows another embodiment. A lifting auxiliary frame 16 is attached to the lower side of the upper end of the newly installed escalator 15 so as to extend obliquely downward, and a suspension wire is attached to the tip of the lifting auxiliary frame 16. 8, the suspension wire 8 is inserted through the wire guide tube 10, and is lifted by a suspension base 11.
