Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of entrances and exits for escalators and moving walkways (hereinafter referred to as escalators, etc.).

[Conventional technology]

For example, as shown in FIGS. 2 and 3, conventional escalator entrances generally include a handrail 1 that rotates endlessly, and a step 2 that rotates endlessly in synchronization with the handrail 1. , a comb plate 3 that covers the inverted part of the step 2, a floor cover 4 that covers the machine room of the escalator, and a truss 5 that holds them.

Comb plate 3 that covers the inverted part of step 2
The platform has a gentle slope so that passengers can safely transfer to Step 2 or from Step 2 to Comb Plate 3. The structure has small steps.

Next, FIG. 4 shows the relationship between the step 2 movement locus 2a and the comb plate 3. The comb plate 3 usually has a surface design and an etched panel 3a that also serves as a non-slip surface, and a steel plate 3b that serves as a strength member to support the passengers and their own weight. The tip of the steel plate 3b has a plurality of combs 7 in the width direction so as to engage with the cleat 2b of step 2. ) is removable to prevent passengers' shoes or foreign objects from getting caught when boarding and disembarking passengers.
It is designed to prevent fingers from getting caught in the event that a passenger falls down at the entrance/exit.

[Problem to be solved by the invention]

By the way, the comb 7, which has the role of protecting the safety of passengers, must be installed so that the gap between it and the cleat 2b in step 2 is extremely small. If the comb plate 3 was manufactured and installed as is on site, there was a problem that the comb 7 would interfere with the cleat 2b of the step 2 even if there was a slight installation error.

For this reason, the current installation of comb 7 is
After step 2 and the steel plate 3b to which the etching panel 3a has been welded are installed separately,
Carefully position the multiple combs 7 on the steel plate 3b in order so as not to interfere with the cleat 2b in step 2, and then insert the combs 7 through the pre-prepared holes in the combs 7 to the tip of the steel plate 3b with a hand drill or the like. After drilling a pilot hole and tapping the pilot hole, the comb 7 is attached to the steel plate 3b as shown in FIG.
This is done by fixing 8 screws on the top.

However, even if these installation and adjustment tasks are easy in a factory, etc., they are extremely difficult to perform and require a great deal of labor and time in places such as installation sites where it is difficult to secure sufficient scaffolding. Currently, we are spending .

The present invention has been made in view of the above points, and
The purpose of this invention is to obtain an entrance structure or installation method for escalators, etc. that is easy to install on site.

[Means to solve the problem]

The present invention provides the following features: (1) At the entrance of an escalator, etc., a truss is provided with a comb plate equipped with a comb having comb teeth that engages with the cleats of the steps circulating in an endless manner, and a comb plate is provided on both sides downwardly. providing the truss with a plate having an angle having a piece extending toward the step, and having a member extending toward the step on the back side;
The one piece of the angle is provided with an engaging portion through which a bolt is screwed, and the comb plate has a mounting structure that is movable in the width direction on the member of the plate by rotation and pushing with the bolt.

(2) For entrances and exits of escalators, etc., the truss is equipped with a comb plate equipped with a comb having comb teeth that engages with the cleats of the steps that circulate endlessly, and the comb plate extends downward on both sides. the truss is provided with a plate having an angle having one piece and a member on the back side extending toward the step;
The one piece of the angle is provided with an engaging part into which a bolt is threaded through, and is fixed to the member through the elongated hole with a gap between the angle and the angle.

(3) At the entrances and exits of escalators, etc., a comb plate equipped with a comb with comb teeth that engages with the cleats of endlessly circulating steps is installed on the truss; a plate provided with a member in a direction in which the member extends toward the step;
After fixing both sides to the truss through an angle with one piece extending downward, the comb plate is placed on the member and a bolt threaded through the one piece of the angle is rotated. The comb plate is positioned in the width direction so that the comb does not interfere with the cleat of the step, and then the comb plate is fixed to the member.

It is something.

[Effect]

If configured or installed as described above, a plurality of combs lined up in the width direction can be easily installed without interfering with the crease of the step.

[Example] An example of the present invention will be described below with reference to the drawings.

Figure 1 is a plan view showing the structure of the board and comb plate at the entrance of an escalator, etc. Figure 6 is a sectional view taken along the - line in Figure 1, and the same reference numerals as in Figures 2 to 5 are shown in Figure 1. indicate the same thing, but 1
Reference numeral 1 designates a plate placed adjacent to the floor cover 4 of the entrance/exit, and an etching panel 11b is fixed to the upper surface of the steel plate 11a by plug welding or the like.
On both sides (upper and lower sides in Figure 1) of the balustrade panel a (not shown), angles 12 and 12' each having an L-shaped cross section are welded, etc., so that one side extends downward and the other side extends toward the balustrade panel. A member 13 is integrally attached to the back surface of the steel plate 11a by welding or the like so as to extend toward the step 2 side. This plate 11 is fixed to the transformer 5 via angles 12, 12'. 14 is a comb plate having a plurality of combs 7 in the width direction at the tip of the steel plate 14a;
An etched panel 14b is fixed to the upper surface of the steel plate 14a except for the comb 7 portion by plug welding or the like. And at both ends of the anti-comb 7 side there are long holes 1 in the width direction.
4c and 14'c are provided, and the comb plate 14 is fixed by threading bolts through the elongated holes 14c and 14'c into tap holes (not shown) provided in the member 13 of the plate 11. Further, nuts 12a, 12'a, for example, are welded to the downwardly extending sides of the angles 12, 12' of the plate 11 to form an engaging portion.
Bolts 12b and 12b' are inserted therethrough, and rotation of the bolts 12b and 12'b pushes the side surface of the comb plate 14 so that it can move on the member 13 in the width direction.

Next, a procedure for installing the plate 11 and the comb plate 14 according to the present invention will be explained. First, the step 2 connected to the truss 5 in an endless manner is installed, and the etched panels 11b,
The member 13 and angles 12, 12' are steel plates 11a.
The plate 11 welded to the angle 12,1
After fixing to the truss 5 via 2', the comb plate 14 is installed in which the etched panel 14bb is welded to the steel plate 14a in advance in the factory and a plurality of combs 7 are fixed to the tip of the steel plate 14a with screws 8 in the width direction. Place the comb 7 on the member 13 of the plate 11 so that it does not come into contact with the cleat 2b of step 2. after that,
To move the comb 7 upward in FIG. 1 so that the cleat 2b in step 2 is positioned approximately at the center of the gap between the comb teeth of the comb 7, rotate the bolt 12b clockwise; If you want to move the comb plate 14 downward in FIG. 1, rotate the bolt 12'b clockwise and push the side surface of the steel plate 14a to move and position the comb plate 14 as a whole. , 14'c and screw the bolts into the tapped holes in the member 13 of the plate 11 to connect and secure the plate 11 and the comb plate 14. Then, if a skirt panel (not shown) is erected in the central part of the etching panels 11b and 14b shown by the two-dot chain lines in FIG. It is not directly visible to the public and does not impair the design.

〔Effect of the invention〕

As described above, according to the present invention, even if a plurality of combs are attached to the comb plate in advance, the entire comb plate can be easily moved in the width direction. Even if there is a problem with the installation, it will not take much time to install.
