Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an escalator assembly method for assembling an escalator integrally in a factory or the like.

(Prior Art) In general, relatively short escalators are constructed by assembling them in a factory, transporting them by truck or the like, and then transporting and installing them at the installation site.

The method for assembling the escalator in one piece at the factory is to first assemble the main body frame 1, commonly called a truss, as shown in FIG. This main body frame 1 is a main frame that supports the entire weight of the escalator, and is installed diagonally by passing over the upper and lower floor beams (not shown) of the building via angle-shaped beams 2a and 2b at both ends. The main body frame 1 is divided into an upper frame part 3a bent in a truss structure, an intermediate frame part 3b straight, and a lower frame part 3C bent in an opposite shape. Each of these frame parts 3a is manufactured by

3b and 3c are arranged in a row and are integrally assembled by fastening them at each end with a plurality of fasteners 4 such as reamer bolts.

In addition, the upper floor side frame part 3a and the intermediate frame part 3b
Various devices that can be assembled are attached to the frame portion 3C on the lower floor side while each is divided into a single unit. That is, a drive device 5 such as a motor, a speed reducer, a control panel, etc., a step drive wheel device 6, and guide rails 7a and 8a for the front and rear wheels of the steps are assembled to the upper frame portion 3a, and the intermediate frame portion 3
Assemble the guide rails 7b and 8b for the front and rear wheels of the step to b,
Guide rails 7 for the front and rear wheels of the steps are installed on the lower floor side frame portion 3C.
Assemble c, 8c and step driven wheel device 9.

In this state, the upper frame part 3a, the intermediate frame part 3b, and the lower frame part 3C are fastened to each other using a plurality of fasteners 4 as described above to assemble them integrally. Guide rail 7a for front and rear wheels of steps
, 8a and 7b, 8b and 7c, and 8c.

The main body frame 1 thus assembled over the entire length of the upper and lower floor sides is supported on the upper surface of the floor 10 by support stands 11 and 12. In other words,
The support stands 11 and 12 are generally called leveling blocks, and are arranged in pairs on the front and back, on the left and right sides. The body frame 1 is mounted and supported, and the partially bent bottom part B of the lower frame part 3C of the main body frame 1 is mounted and supported on the left and right support stands 12 at the rear.

In this state, inside the main body frame 1 there is a step equipment M13 (step chain 14 and a large number of steps 1) that are escalator supplies.
5) is incorporated in an endless manner so as to be rotationally drivable, and the left and right handrails 16 are assembled and fixed on the main body frame 1. When assembling the balustrade 16, a plurality of balustrade panels 16a, such as glass plates, divided into sections of several meters are aligned straight along the piano wire 17 stretched in the longitudinal direction, and the same is done. Deck board 16 divided into multiple parts
b are connected and assembled and fixed.

When the escalator is almost completed, it is transported by truck or the like to the installation site, and then hung diagonally by passing it to the upper and lower floor beams (not shown) of the building via the wires 2 m and 2 b at both ends of the main body frame 1. Erection and fixation. Finally, the installation is completed by carrying out construction work on the surrounding building, installation of exterior panels (not shown) around the main body frame, and work on incidental equipment.

(Problems to be Solved by the Invention) As described above, in the conventional floor-mounted integral assembly method of escalators in factories, the upper end lower part A of the main body frame 1 and the lower part B bent halfway on the lower floor are connected to the floor. The escalator is mounted and supported on support stands 11 and 12 on top of the escalator, and in this state the escalator equipment such as the step device 113 and the left and right handrails 16 are assembled.
The support points A and B of the main body frame 1 at this time and the main body frame 1 when installed between the upper and lower floor beams at the actual building installation site.
Since the support points C and D (both ends 2a and 2b) are different, the main body frame 1 is different during assembly and installation.
have different deflection characteristics. For this purpose, especially the main body frame 1
There is a problem in that the assembly accuracy of the left and right handrails 16 assembled above cannot be maintained at factory quality, and distortions etc. occur in the handrails 16 when installed on site.

For example, in the case of a two-seater wide escalator with a floor height of 5 m, when it is assembled on the floor as described above, it will bend approximately 3 mm downward at position E, which is between support points A and B of main body frame 1, and the lower floor will At the D position of the end beam 2a, it jumps upward by 0.7 ■l. The step device 1 is attached to the half frame 1 in this state.
3, the downward deflection at the E position increases to 611 and the bounce at the D position increases to 1.8 tam. In this state, when the left and right handrails 16 are assembled and fixed on the main body frame 1 and carried to the site as a nearly completed product and installed, the main body frame 1 is supported at the support points C and D at the upper and lower floor ends, so that the above-mentioned The downward deflection at position E increases by lO, 3 mmg. In other words, when the parapet 16 is assembled and fixed on the main body frame 1 supported at support points A and B at the factory, the main body frame 1 is at the support point C when installed on site.

By increasing the amount of deflection by being supported by D, even if the middle part is simply considered, the 4
Deflection of mm or more occurs. For this reason, the balustrade panels 16a that are connected one after the other with a gap equal to the joint etc. move in the direction that the gap between them decreases, and a buckling force is generated in the deck boards 16b that are connected one after the other without a gap. Distortion occurs.

In such a case, if some of the parapet panels 16a or deck boards 16b of the parapet 16 are removed for maintenance work or overhaul work, and even if you try to restore the parapet panels 16a or deck boards 16b after the work is completed, they may be stuck in their original positions. First, there was a problem that required re-alignment.

In particular, the lower-floor frame portion 3c of the main body frame 1 is often extended to fit between the beams of the building, but in such a case, the moment when the lower-floor frame portion 3C moves away from the support point B in the direction D increases. Therefore, the downward deflection at the intermediate E position between the support points A and B of the main body frame 1 is due to the above-mentioned 6
The difference from the deflection 10.3a+m of the main body frame 1 in the on-site installation state increases, and the above-mentioned problems tend to get worse.

The present invention has been developed in view of the above circumstances, and is an integral assembly method for escalators placed on the floor in factories, etc., while maintaining the main body frame in the on-site installation state of the building and the deflection characteristics such as between roads, and assembling escalator supplies. To provide an escalator assembly method that allows the entire assembly to be performed, maintains the assembly accuracy of handrails, etc. at factory quality even after the escalator is installed on site, and prevents defects such as distortion.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention assembles the main body frame of an escalator over the entire length of the upper and lower floors, and places the lower part of the upper floor end of this main body frame on a support base. On the other hand, by placing the lower part of the lower end of this main body frame on a relatively tall stand whose angle can be adjusted, both ends of the main body frame are supported in a state floating off the floor. It is characterized by assembling escalator equipment such as a step device to the frame.

(Function) With the escalator assembly method having the above configuration, when supporting the main body frame on the floor in order to assemble the escalator integrally at a factory, etc., the lower end of the upper floor side of the main body frame is placed on the support stand. Comparison where the angle of the lower end of the lower end of the main body frame can be adjusted without supporting the bent bottom part B of the lower end of the main frame as in the conventional case. Since the main body frame is mounted and supported on a tall stand, both ends of the main body frame are supported in a state that it is floating off the floor. With this, the main body frame has the installation state where it is passed between the upper and lower floor beams of the building at the actual installation site, and the deflection characteristics such as the road gap are achieved, and the escalator supplies are assembled as is to assemble the entire escalator. By transporting the escalator assembled in this way to the building installation site and installing it by passing the hook between the upper and lower floor beams, the assembly precision of the left and right handrails can be maintained at factory quality, and distortions etc. can be avoided. It disappears.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, components that overlap with those in FIG. 4 are given the same reference numerals to simplify the explanation.

As shown in FIG. 1, first, as in the past, at a factory, etc., the main frame 1 of the escalator is divided into two parts: an upper frame part 3a which is bent in a U-shape, and an intermediate frame part 3b which is straight. The frame parts 3c on the lower floor side bent in the shape of a square are arranged in a line and are integrally assembled by fastening them at each end with a plurality of fasteners 4 such as reamer bolts.

The upper frame portion 3a includes a drive device 5 such as a motor, a speed reducer, and a control panel, a step driving wheel device 6, and a guide rail 7a for the front and rear wheels of the steps.

8a, and the guide rails 7b and 8b for the front and rear wheels of the steps are assembled to the intermediate frame part 3b, and the lower frame part 3c is assembled.
The guide rail 7C18c for the front and rear wheels of the step and the step driven wheel device 9 are assembled in the upper frame part 3a, the intermediate frame part 3b, and the lower frame part 3 in this state.
C and C are fastened to each other by a plurality of fasteners 4 as described above and assembled integrally, and the guide rails 7a, 8a and 7b, 8b and 7c for the front and rear wheels of the steps are assembled together.

While placing the lower part A of the upper floor side end of the room 1 on the support stand 11,
By mounting the lower end F of the lower floor side of the main body frame 1 on the stand 20, the main body frame 1 is supported at both ends in a state floating from the floor 10.

In other words, the upper end lower part A of the main body frame 1 is placed on a pair of left and right support stands 11, which are generally called leveling blocks, as in the past, and the height of each of the left and right support stands 11 is adjusted. It is supported by fine adjustment to achieve horizontality in the width direction.

On the other hand, the lower side of the main body frame 1 does not support the bent bottom part B of the lower frame part 3c of the main body frame 1 in the middle as in the conventional case. The bottom end beam 3d having an angular cross-section at the position is mounted and supported on a pair of relatively tall left and right stands 20.

As shown in FIGS. 2 and 3, the pair of left and right stands 20 are each provided with a pair of front and rear caster wheels 22 at the bottom of a base 21, and an anti-sway bolt 23 that can be raised and lowered from the floor surface. A vertically elongated support frame 24 is erected and fixed on this base 21, and one screw rod 25 is vertically inserted into the upper frame member 24a of this support frame 24 so as to be movable up and down. Two height adjustment nuts 26 and 27, upper and lower, are screwed together, and a head 28 is rotatably attached to the upper head 25a of the threaded rod 25 via a pin 29. The height of the head 28 can be individually adjusted by operating the screw rod 25 to move it up and down, and the angle of the head 28 can be adjusted by rotating it via the pin 29. In addition, the left and right stands 20 connect the support frame 24 to each other using a plurality of connecting beams 3.
0, they are integrally connected to each other with an interval equal to the width of the main body frame 1.

Such a pair of left and right stands 20 is stably installed on the floor 10 by tensioning the anti-sway bolts 23, and the heights of the left and right heads 28 are adjusted equally by the respective threaded rods 25, and the heights of the left and right heads 28 are adjusted to be equal. An angled horizontally long support plate 31 having claws 31a for preventing displacement is installed. In this state, by mounting the bottom end beam 3d at the lower end F of the lower end of the lower frame portion 3C of the main body frame 1 on the upper surface of the support plate 31, the support plate 31 is lowered together with the head 28. The bottom end beam 3d is received at an angle that follows the inclination angle θ of the floor side frame portion 3C, and the edge of the bottom end beam 3d is stopped by the claw 31g for preventing slippage. The lower part F of the lower end of the main body frame l is stably supported.

As shown in the figure, the left and right stands 20 have their respective bases 21 attached to support stands 1 which are the same leveling blocks as conventional ones.
It is also possible to finely adjust the height by placing it on top of 2.

As described above, when the main body frame 1 is supported by the upper end lower part A and the lower end lower part F in a state floating from the floor 0, a step device 13 which is an escalator equipment is placed inside the main body frame 1. (a step chain 14 and a large number of steps 15) are incorporated in an endless manner so as to be rotationally drivable. In addition, a piano wire 17 is stretched in the longitudinal direction on the main body frame 1, and this piano wire 1
A plurality of balustrade panels 16a such as glass plates are arranged in series while being aligned straight along the line 7, and deck boards 16b divided into a plurality of pieces are similarly arranged in series to assemble and fix the left and right balustrades 16.

Once the escalator is almost completed, it is transported by truck or the like to the installation site, and the hooks are passed to the upper and lower floor beams (not shown) of the building via the beams 2a and 2b at both ends of the main body frame 1, as in the conventional case. This allows the structure to be erected and fixed diagonally. Finally, the installation is completed by carrying out construction work around the area, installing an exterior plate (not shown) around the main body frame, and working on incidental equipment.

By doing this, when assembling the escalator in a factory, etc., the main body frame 1 can be made to have the same flexural characteristics as the installation condition where the bridge is passed between the upper and lower floor beams of the building at the actual installation site, and the bending characteristics such as the road gap. Since the entire escalator can be assembled by assembling the supplies, the escalator is transported to the building installation site and the main body frame 1 is inserted between the upper and lower floor beams.
, D. If the hangings are passed and installed, the assembly precision of the left and right handrails 16, etc. can be maintained at factory quality, and distortions etc. will not occur.

〔Effect of the invention〕

Since the escalator assembly method of the present invention is performed as described above,
Although this is an integrated floor-mounted assembly method for escalators in factories, etc., it is possible to assemble the entire escalator by assembling escalator supplies while maintaining the main body frame in the building's on-site installation state and the deflection characteristics such as between roads. Even after installation, it is possible to maintain the assembly precision of the handrails and the like at factory quality, thereby preventing defects such as distortion.
