Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electric road in which a step is not generated between adjacent treads, and more particularly to an electric road with an improved tread shape.
[0002]
[Prior art]
Normally, as disclosed in Patent Documents 1 and 2, a motorized road is circulated by connecting endless treads having treads having substantially the same size as treads of escalator steps.
[0003]
The tread includes a cleat body, a strength member supporting the cleat body, and an end frame body supporting the strength member at both ends in the width direction.
[0004]

[Problems to be solved by the invention]
The electric roads described in Patent Literatures 1 and 2 have a large tread plate height because the cleat body, the strength member, and the end frame that constitute the tread plate are simply stacked in the tread plate height direction. As a result, the travel space required for the outward travel of the tread plate, the travel space required for the return travel, the safety space secured above and below these, and the frame body located between the forward travel travel space and the return travel travel space When the installation dimensions of the horizontal girder members, which are the constituent members of the above, are matched, there is a problem that the dimension of the frame body for housing these members in the height direction becomes large.
[0006]
In addition, since the height of the frame at the turning portion of the tread is determined by the depth and height of the tread, the height of the frame is reduced on a motorized road having ordinary treads. It was extremely difficult.
[0007]
An object of the present invention is to provide an electric road that can reduce the height dimension of a frame.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a strength member that supports a cleat body having juxtaposed cleats from below, a lateral member that supports the cleat body from below, and extends downward from the lateral member. A vertical member was formed, and an end frame supporting the wheel was connected to the vertical member.
[0009]
Furthermore, in an electric road in which a plurality of treads provided with wheels on both sides in the width direction are connected endlessly and circulated between the entrances and exits, the depth of the treads is set to be greater than three times the diameter of the wheels. It was shortened.
[0010]
As in the above configuration, the weight of the cleat body transmitted by the horizontal member is received by the vertical member, and the vertical member and the end frame are connected from the horizontal direction. Fastening parts and the like are not added in the height direction of the tread. In addition, since the load of the cleat body is supported by the longitudinal members of the strength member, the transverse members of the strength member can be made thin. As a result, in order to secure the strength for supporting the cleat body, it is possible to eliminate the factor of increasing the height of the tread plate by forming the strength member in a hat shape. For this reason, it is possible to reduce the height dimension of the tread plate, reduce the turning radius of the direction change portion of the tread plate, and reduce the height dimension of the intermediate portion of the frame body in which the forward and return paths of the tread plate are formed. be able to.
[0011]
Further, since the depth dimension of the tread can be reduced, the turning radius of the tread in the tread direction changing portion can be further reduced, and thereby the height dimension of the direction changing portion of the frame can be further reduced.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0013]
In general, the electric road 2 installed on the building structure 1 includes a frame 3 installed in a concave groove 1P formed by excavating the ground of the building structure 1 and two longitudinal ends of the frame 3. The floors 4 and 5 provided, a plurality of treads 6 connected endlessly between the two floors 4 and 5 and circulating, and standing on the frame 3 along both sides in the moving direction of the treads 6. And a moving handrail 8 guided by the periphery of the balustrade 7 and synchronously moved with the tread plate 6.
[0014]
The tread plate 6 includes left and right end frames 9A and 9B disposed on both sides in the width direction, a strength member 10 extending over the left and right end frames 9A and 9B, and a passenger fixed to the strength member 10 And a wheel 12 supported by the end frames 9A and 9B.
[0015]
Here, the cleat body 11, for example, is formed by bending a stainless steel sheet alternately and continuously in a wave crest to form a large number of cleats along the tread plate depth direction, and a space formed at a longitudinal end of the cleat. It is closed by caulking and filling. Note that the cleat body 11 may be formed of an aluminum molded product or another material.
[0016]
The strength member 10 includes a first strength side 13 and a second strength side 14, which have substantially the same length as the width dimension of the cleat body 11. The first strength side 13 and the second strength side 14 are each formed into a L-shaped cross section by bending a steel plate, and the horizontal sides 13H and 14H serving as lateral members for supporting the cleat body 11 from below. And vertical sides 13V and 14V which are vertical members extending downward from one ends of the horizontal sides 13H and 14H along the cleat body depth direction. The first strength side 13 and the second strength side 14 are arranged in parallel with a gap in the depth direction of the cleat body, and the groove bottoms of the cleat body 11 are provided on the horizontal sides 13H and 14H, for example, by well-known spot welding or the like. It is fixed by fixing means.
[0017]
Each of the end frames 9A and 9B has a shaft support 15 extending in the depth direction of the cleat body, and a connecting portion 16 projecting from the shaft support 15 in the width direction of the cleat body. The front end of the shaft support 15 in the tread-board traveling direction is displaced toward the outer side in the tread-board width direction as compared with the rear end in the tread-board traveling direction. In such a shaft support 15, a first shaft support is provided at a front end in the traveling direction of the tread plate, and a bearing 17 that supports the axle 12 </ b> S of the wheel 12 is fixed thereto. The rear end of the shaft support portion 15 in the tread plate traveling direction has a length protruding from the rear end in the depth direction of the cleat body 11, and a second shaft support portion is provided at the protruding portion, and a wheel serving as a rear wheel there. A shaft support groove 18 that receives a bearing 17M provided on the 12R axle 12RS is formed. The shaft supporting groove 18 is formed to be long along the depth direction of the cleat body, and the bearing 17M is supported so as to be slidable only in the shaft supporting groove 18.
[0018]
The connecting portion 16 is formed in a U-shaped cross section to be inserted between the first strength side 13 and the second strength side 14 of the strength member 10, and the first strength side 13 and the second strength side 14 has vertical sides 16V that are in contact with the respective vertical sides 13V and 14V.
[0019]
In the above configuration, the strength is obtained by fastening the vertical sides 16V of the connecting portion 16 to the vertical sides 13V and 14V of the first strength side 13 and the second strength side 14 by a known fastening means such as a bolt B. End frames 9A and 9B are integrally assembled at both ends in the width direction of the member 10. As described above, the cleat body 11 is fixed by spot welding on the horizontal sides 13H and 14H of the strength member 10 assembled as described above. When the cleat body 11 is spot-welded to the horizontal sides 13H, 14H, it may be performed before the end frames 9A, 9B are fixed to the strength member 10.
[0020]
The tread plate 6 thus configured is connected endlessly by connecting the axle 12S, which is supported by the bearings 17 of the end frames 9A and 9B, to an endless tread chain 19. Then, the tread plate chain 19 is wound around sprockets 20A, 20B pivotally supported at both ends in the longitudinal direction of the frame 3, and any one of the sprockets 20A, 20B is driven. The wheels 12 are rolled on guide rails (not shown) laid on the floor and circulate between the floors 4 and 5.
[0021]
In the above configuration, only the front wheel 12 is supported at a fixed position with respect to the tread plate 6, and the rear wheel is, as shown in FIG. As shown in FIG. 2, the wheel 12R supported at a fixed position of the shaft support 15 of the 6R is also used by being fitted into the shaft support grooves 18 of the end frames 9A and 9B of the tread plate 6. Become. Further, the wheel 12 serving as the front wheel of the tread plate 6 also serves as a rear wheel of the tread plate 6F adjacent to the front side (upper side in the drawing) in the tread plate traveling direction. For this purpose, as shown in FIG. 4, the front end in the traveling direction of the end frame 9A of the tread 6R is disposed at the rear end of the end frame 9A of the tread 6 in the traveling direction of the tread, so as to overlap in the tread width direction. In addition, the shaft support portions 15 of the end frame members 9A and 9B are positioned so as to protrude from both ends in the width direction of the cleat body 11. In this manner, by positioning the shaft supporting portions 15 of the end frame members 9A and 9B so as to protrude from both ends in the width direction of the cleat body 11, the shaft supporting portion 15 contacts the lower portion of the adjacent cleat body 11 at the tread plate direction changing portion. To prevent
[0022]
With the above-described configuration, the weight of the two adjacent treads 6, 6F and the load acting on the treads 6, 6F are shared by one wheel 12, so that the wheels are moved forward and backward with respect to one tread, respectively. The number of wheels can be reduced as compared with the configuration in which 12 are provided.
[0023]
According to the present embodiment, the height of the frame 3 of the electric road 2 can be reduced.
[0024]
That is, the cleat body 11 is directly supported by the horizontal surfaces 13H and 14H, and the two vertical sides 13V and 14V that bear the supporting force (load) are fastened to the end frame members 9A and 9B from the lateral direction, and the end portions are formed. Since the height H (FIG. 1) of the frames 9A and 9B is within the height of the cleat body 11 plus the height of the strength member 10, the strength member 10 and the end frame 9A, The height of the tread plate 6 can be reduced as compared with the related art in which the tread 9B is connected in the height direction.
[0025]
On the other hand, since one wheel is also used as a front wheel and a rear wheel of front and rear adjacent wheels, the depth dimension of the tread is reduced as compared with a configuration in which two wheels are supported on one tread in the past. As a result, the radius of rotation of the tread plate 6 at the direction change portion can be reduced. The interval between the adjacent wheels 12-12 </ b> R changes in the direction change portion of the tread 6, and the change in the interval is caused, for example, by the end frame members 9 </ b> A, 9 </ b> B of the tread 6 having the axle 12 RS of the wheel 12 </ b> R of the following tread 6 R preceding. The position is changed in the shaft support groove 18 of FIG.
[0026]
As described above, since the height of the tread plate 6 can be reduced and the turning radius of the tread plate 6 at the turning portion can be reduced, the height of the frame body 3 at the tread turning portion can be reduced. Also, the height of the frame 3 at the intermediate portion where the tread plate 6 reciprocates can be reduced. The fact that the height of the frame 3 can be reduced means that the concave groove 1P to be excavated to bury the frame 3 in the ground of the building structure 1 may be shallow, and the amount of civil engineering work is reduced. be able to. When the frame 3 is installed in the building structure 1, the height of the vertically adjacent floor can be reduced by the reduced height of the frame 3.
[0027]
By the way, in the above embodiment, the width dimension W of the tread 6 is the same as the tread of the conventional electric road, but the depth L can be shorter than the tread depth of the conventional electric road. . However, by setting the depth dimension L of the cleat body 11 to, for example, three times or less the outer diameter dimension of the wheel 12, the length can be reduced to about half the length as compared with the related art.
[0028]
With such a configuration, the turning radius of the tread plate 6 in the direction changing portion can be further reduced as compared with the conventional tread plate, and as a result, the height of the frame 3 can be further reduced.
[0029]
By the way, the width W of the treads 6 on which the passengers ride on the electric road is generally about 1000 mm so that two people can ride side by side, but in order to further improve the convenience, the width W of the treads 6 is set to about 1600 mm. Is being considered. However, when the width of the tread plate 6 is set to 1600 mm in the short tread plate 6 such that the depth of the tread plate is not more than three times the outer diameter of the wheel 12, a problem occurs that the tread plate 6 is easily bent by a passenger.
[0030]
Therefore, the second embodiment of the present invention shown in FIGS. 6 and 7 provides a structure in which even a tread having a short depth and a large width has a small bending.
[0031]
The second embodiment is almost the same as the configuration according to the first embodiment. The configuration different from the first embodiment is the configuration of the strength member 21. That is, the third strength side 22 is arranged between the first strength side 13 and the second strength side 14 which are arranged at an interval. The third strength side 22 has the same length dimension as the first strength side 13 and the second strength side 14, and has a horizontal side 22H and vertical sides 22V extending perpendicularly downward from both ends thereof. It is formed in a so-called U-shaped cross section.
[0032]
The horizontal side 22H of the third strength side 22 thus formed is brought into contact with the cleat body 11 from below, and the vertical sides 22V, 22V are changed to the vertical sides 13V, 14V of the first strength side 13 and the second strength side 14. To accompany. Next, with the connecting portions 16 of the end frames 9A, 9B inserted between the vertical sides 22V, 22V of the third strength side 22, the vertical sides 13V-22V-16V, and 14V-22V-16V are connected. It is connected from the lateral direction by fastening means such as bolts B. Note that the horizontal side 22H of the third strength side 22 does not necessarily need to be supported in contact with the bottom of the cleat body 11, and a gap may exist between the horizontal side 22H and the bottom of the cleat body 11. Further, the vertical sides 13V-22V-16V and 14V-22V-16V may not be directly in contact with each other, but may be fastened with a spacer interposed therebetween.
[0033]
According to the second embodiment configured as described above, the number of the vertical sides 13V-22V and 22V-14V receiving the cleat body 11 is doubled as compared with the first embodiment, so that the depth dimension is increased. Can be suppressed in the width direction of the cleat body 11 having a short width and a long dimension in the width direction.
[0034]
Incidentally, according to the present embodiment, the frame 3 in the portion E in FIG. 5, which had a height dimension of about 1000 mm in the past, had a height dimension of about 500 mm in the related art. The frame 3 in the portion M in FIG. 5 could be reduced to about 350 mm.
[0035]
FIG. 8 shows the third embodiment. What differs from the second embodiment is the shape of the strength member 23. That is, in the second embodiment, the strength member 21 has a configuration in which the three strength sides of the first strength side 13, the second strength side 14, and the third strength side 22 are combined. Has formed the strength member 23 by bending a single steel plate. More specifically, the vertical sides 13V and 22V of the first strength side 13 and the third strength side 22 and the second strength side 14 and the third strength side 22 of the second embodiment that are fastened together are the same. The strength members 23 were formed from a single steel plate by continuously bending the lower ends of the vertical sides 14V and 22V to be fastened without separating them.
[0036]
The other structure is the same as that of the first and second embodiments, and the description thereof will not be repeated.
[0037]
According to this embodiment, the same effects as those of the first and second embodiments can be obtained, and also, there is an effect that the number of components of the strength member 23 can be reduced.
[0038]
By the way, in the first to third embodiments, the horizontal sides 13H, 14H of the first strength side 13 and the second strength side 14 constituting the strength member are bent at substantially right angles from the vertical sides 13V, 14V. As shown in the fourth embodiment shown in FIG. 9, the cleats are formed so that the inclined sides 13S, 14S are interposed between the horizontal sides 13H, 14H and the vertical sides 13V, 14V, respectively. The bending of the end of the body 11 in the traveling direction may be suppressed. Further, the connecting portion 16 of the end frame members 9A and 9B in the first to third embodiments is formed in a U-shaped cross section which opens downward, as shown in the fourth embodiment shown in FIG. In this manner, the opening may be formed in a U-shaped cross section that opens upward. That is, regardless of whether the opening is upward or downward, the vertical sides 16V and 16V of the connecting portion 16 that are connected to the vertical sides 13V and 14V of the first strength side 13 and the second strength side 14 from the horizontal direction. This is because the position does not change. Therefore, depending on the type of the cleat body 11, it is possible to determine whether the opening is the connection portion 16 facing upward or the connection portion 16 facing downward. Note that FIG. 9 has basically the same configuration as each of the embodiments shown in FIGS. 1 to 3, and thus the description thereof will not be repeated.
[0039]
In the first to fourth embodiments, the strength members 10, 21, and 23 are formed by bending a steel plate. However, the material and shape are not particularly limited. The vertical member bears the load acting on the cleat body, and the end frame is connected to the vertical member from the horizontal direction. One wheel is fixed to one tread, and the other wheel advances. It is supported so that it can be displaced in the direction.
[0040]
