れる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator or a moving walkway machine room. 2. Description of the Related Art A conventional machine room of an escalator will be described with reference to FIGS. A truss 1 which is a main frame of an escalator which is housed and supported on the entire escalator and is bridged between floors is an upper chord 2a, a lower chord 2b, 2c, a diagonal beam 2d and a cross beam 3a mainly composed of a section steel. 3b and the like. A machine room 4 for accommodating a drive unit for the escalator is installed on the upper floor of the truss, and a drive unit 5 including an electric motor and a worm reducer is directly fixed to a cross beam 3c of the main frame of the floor with bolts, and its output is output. The sprocket 6 is connected via a drive chain 8 to a chain wheel 7 of a step device of the escalator. [0004] Recently, there has been an increasing demand for energy saving along with the renovation of the existing escalator, and in order to meet this demand, it has been necessary to replace it with an energy-saving drive device. That is, the conventional worm speed reducer is about 15% less efficient than a spur gear type helical speed reducer in terms of mechanical efficiency, so that energy saving can be realized by replacing it with a helical type. However, the mechanism and mounting structure of the worm speed reducer and the drive device using the helical speed reducer are different. The worm speed reducer 9 includes the cross beams 3a, 3
The conventional mounting method is that the driving device fixing beams 3c, 3c are fixed by bolts. In an existing building or the like, when repairing or modernizing an elevator of an existing escalator, there is a problem that a firearm (fire) cannot be used for disaster prevention, and a welding machine and a fusing machine cannot be used naturally. Therefore, when mounting is performed differently from the conventional method, the members must be fixed by fastening with bolts or the like. A worm speed reducer has a small installation area, while a helical speed reducer requires a large floor area. The worm speed reducer is a mounting method in which the worm speed reducer is directly installed on the drive device fixing beam 3c. The mounting surface is not a uniform flat surface, it is configured in the form of a mounting seat on a frame of a mold steel such as an angle and has many irregularities, and it is not in a state where other types of driving devices can be mounted immediately, and during operation There was a problem that it was difficult to clean the machine room cleaning surface such as accumulated dust. [0008] In particular, energy saving is progressing at present, and a recent escalator uses a helical speed reducer of a spur gear system, and the production of the existing worm speed reducer is stopped due to poor transmission efficiency. Therefore, if the existing worm speed reducer breaks down and there is no replacement part, it is necessary to switch to the current helical speed reducer, but it cannot be mounted as it is because of incompatible mounting. Moreover, since it is an existing building facility, a welding machine or the like, which is a firearm (fire), cannot be used for constructing a mounting base for the helical speed reducer for disaster prevention (there is a risk of building fire). The present invention solves these problems,
For the large installation area of the helical speed reducer, a new floor is installed so that it can be installed firmly and the floor surface is flat, making it easy to change to the energy-saving helical speed reducer and easy to replace the drive unit of the existing escalator It is intended to be able to be realized. According to the present invention, there is provided an escalator in which a driving mechanism is directly fixed to a main frame of a machine room, a mounting hole is formed in the main frame, and a receiving angle is formed in the mounting hole. Mount to form a mounting seat and divide it into multiple pieces on this mounting seat
The drive plate is fastened by placing the floor plate on it ,
Attach the machine bed receiving angle to the floor plate,
Place the machine bed on this machine bed receiving angle
And press the top surface with the machine bed holding angle,
It is characterized by being integrally fastened and fixed on the floor plate . The receiving angle is mounted on the main frame to form a mounting seat .
If you put the floor plate divided into multiple pieces on this mounting seat
First, place the machine bed on the machine bed receiving angle mounted on the floor plate, and
It was mounted on the machine bed because it was
In addition, the replacement of the drive device is facilitated. [0012] Incidentally, since there is a floor plate even when entering the machine room, etc. installed after cleaning, indoor movement, the cleaning can be easily performed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS. The floor plate of the present invention is installed in a trussed machine room as follows. Holes (A) are provided at a plurality of positions on the vertical side surfaces of the cross beams 3a and 3b of the truss with a special tool lug borer or the like. On the other hand, a side hole B is provided in the receiving angle 11 of the floor, and a bolt is inserted between the side hole B and the hole (A) to receive the receiving angle 1.
Fix 1 An upper hole C is provided on the upper surface of the receiving angle 11, and floor plates 12, 13, and 14 are placed on the upper hole C. That is, the floor plate 12 is placed on the receiving angle 11 so as to come to the drive chain side, and is fixed by providing a long hole D for mounting, and connecting bolt E to a screw hole C provided in the receiving angle 11 from the upper side. To conclude. The screw hole C may be formed by attaching a weld nut to the lower surface of the receiving angle 11. In this case, it is only necessary to screw the connection bolt E.
The floor plates 13 and 14 are similarly attached. The level plate 15 includes floor plates 12, 13,
14 is provided in order to eliminate the steps of the floor plates 12, 13, and 14 when the floor plates 12, 13 and 14 are mounted.
When the floor plates 12, 13, and 14 are abutted with each other, they are arranged and fixed in a zigzag manner on the back surfaces of 3, 14;
The level plate 15 is engaged so as to be inserted into the back side to form a flat surface without a step. Next, the machine bed receiving angle 16 (FIG. 3) is attached to the floor plate 12 and the floor plate 13. At that time, the machine bed receiving angle 16 is
The fixing position of the connection hole 18 is matched to the fixing hole 17 of No. 3 and fixed. Further, the fixing hole 17 is formed with a tap or a screw hole on the back side with a weld nut or the like. [0018] Place the Mashinbe' de on anti-vibration rubber 19 of the machine bed receiving angle 16, further, the Mashinbe'
The machine bed holding angle 21 (FIG. 4) is placed on the door via a vibration isolating rubber 19b, and bolts are passed through the mounting holes F and the holes G of the fixing plate 22 of the machine bed receiving angle 16 and are fixed with nuts. As described above, the machine bed receiving angle 16
The machine bed is fixed by the machine bed holding angle 21. A helical speed reducer 23 is formed by combining a speed reducer, a motor, a brake, and the like on the upper part of the machine bed. By the way, in order to center the helical speed reducer 23, four support frames (supports) 24 and two support frames 25 in the front-rear direction are provided on the floor plates 13 and 14 in advance in the left-right direction. The support frame 25 is provided with a push bolt 26 as shown in FIG. 1, and is arranged at a position where the machine bed can be pushed in. Although the above floor plate is constituted by division,
This can be configured integrally. [0022] Since the floor of the escalator machine room is configured as described above, when the worm speed reducer of the existing escalator is out of order for replacement, the worm speed reducer is removed from the existing escalator main body, and then the main frame of the truss. A plurality of mounting holes are provided on the vertical side surface of the cross beam with a rag borer or the like, and an L-shaped mounting seat is provided in the mounting hole.
And a floor plate is mounted on it. This floor plate covers the above-mentioned mounting seat surface so as not to receive any influence of the mounting seat surface of the speed reducer by integral or splitting. Then, centering of the driving device in the left-right direction is performed with an adjustment bolt (FIG. 2). On the other hand, for adjusting the tension of the drive chain 8, the tip of the bolt is a flat plate so that the tension can be obtained by pushing the machine bed with the push bolt 26, and rubber is attached to the tip. Then adjust the tension. Further, when the operator performs an inspection for maintenance or the like at a later date, since the floor plates 12, 13, and 14 are horizontally installed in the machine room, cleaning is easy and safety is high. Furthermore, in order to wipe off when oil or the like adheres to the bottom of the floor plate, a wiping hole H large enough to allow a hand to enter the floor plate 14 is cut. [0025] With this configuration, the worm speed reducer can be replaced with a helical speed reducer, and the floor surface is flat, safe, easy to clean, semi-permanently usable by laying plates, and the loading is divided. It can be done easily because of the formula. Further, since the floor plates are all screw-fastened, firearms are not used and there is no fear of building fire, so that the floor plates are safe. According to the present invention, since the floor plate can be easily installed in the machine room of the existing escalator, it is possible to easily replace the worm speed reducer with the helical speed reducer. Further, since the transmission efficiency of the helical reducer can be improved, it is economical in terms of energy saving. The simplification of the structure of the floor plate and the simplification and reduction of the weight of the floor plate facilitate the replacement work, and provide advantages such as easy cleaning and improved safety in maintenance.
