Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a state quantity measuring method for a frame of a passenger conveyor for measuring a state quantity such as a length of a frame of an escalator or the like.

[0002]

2. Description of the Related Art When a passenger conveyor, such as an escalator, is renewed due to deterioration over time, the existing handrails, steps, etc. are left as they are on the building side and only the balustrade is renewed in order to redesign only the design. Is often done.

FIG. 10 is a schematic side view showing an existing escalator.

The outer shell of the escalator shown in FIG. 10 is
It is mainly composed of a balustrade 2 and a frame 1 supporting the balustrade 2. The frame 1 includes an upper chord member 1a and a lower chord member 1b. For example, the upper chord member 1a includes a lower horizontal portion 4C and an upper horizontal portion 4D, and an inclined portion 4E connecting the lower horizontal portion 4C and the upper horizontal portion 4D. Have.

When the escalator was initially installed, the inclined portion 4E of the upper chord member 1a of the frame 1, for example, had a linear shape, but it often bends into a curve F due to aging. Along with this, the lower horizontal portion 4C
The lower intersection A where the inclined portion 4E intersects with the inclined portion 4E changes to the lower intersection C, and the upper intersection B where the inclined portion 4E and the upper horizontal portion 4D intersect changes to the upper intersection D.

As described above, even when only the balustrade 2 is renewed, it is desired to shorten the construction period. Along with this, in the assembly factory, a new blocked balustrade 2 is assembled in advance on a virtual frame of the existing frame 1 to which the renewed balustrade 2 is attached, and the blocked balustrade 2 is carried to the site to create a frame. It is being installed at 1.

When such a work is performed, even if the frame 1 is bent and distorted as shown by the curve F in FIG. 10, the pedestal in the assembly factory is manufactured in the same bent and distorted shape. Things are almost impossible. Therefore, in an assembly factory, the balustrade 2 which is made into a block is assembled on a gantry formed in a linear shape.

FIG. 11 is a schematic side view of an existing escalator showing a preparatory work for mounting a new balustrade 2.

As shown in FIG. 11, when the frame 1 is warped or distorted, a plurality of interfaces 10 are connected to the frame 1 to form a straight line G connecting the lower intersection point C and the upper intersection point D. Is installed. Blocked balustrades 2 will be attached along a straight line G formed by the upper surfaces of these interfaces 10. Therefore, in order to facilitate the attachment of the balustrade 2 which is made into a block, it is necessary to accurately grasp the amount of state such as the length and deflection of the frame 1.

From the above, conventionally, in order to confirm the length of the straight line G connecting the lower intersection C and the upper intersection D of the frame 1 shown in FIG. Has measured the length of the frame 1 and the like.

[0011]

As described above, conventionally, in the case of measuring the length of the straight line connecting the lower intersection C and the upper intersection D of the existing frame 1 shown in FIG. There is a problem in that it requires a complicated work of installing a measure or a piano wire and reading the numerical values, and that this work takes time and the efficiency of the measurement work cannot be expected to improve. That is, with the conventional technology, it has been difficult to realize a shortened construction period for renewing the balustrade 2. Also,
As described above, there is a problem in that reading errors are likely to occur when reading numerical values, and the measurement accuracy is likely to decrease.

In addition, when installing or extending a measure or a piano wire, in addition to the balustrade 2, it is necessary to remove the parts related to the frame, ballast, and handrail near the lower intersection C or the upper intersection D, which requires a large amount of work. In this respect as well, there is a problem that the improvement of the efficiency of the measurement work cannot be expected.

Further, when the corners of the lower intersection C and the upper intersection D of the frame 1 are deformed due to deterioration over time and become so-called R-shaped, the lower intersection C and the upper intersection D are determined. However, there is a problem that the measurement accuracy of the length of the straight line connecting the lower intersection point C and the upper intersection point D is reduced from another viewpoint. Such a decrease in measurement accuracy has led to a decrease in the efficiency of the work of attaching the new balustrade 2.

A technique capable of quickly measuring the distance to the target point is disclosed in, for example, Japanese Patent Laid-Open No. 7-77424. This prior art is provided with an optical surveying instrument, that is, a transit fixed body having a calculation function and a position indicator. The transit fixed body projects light in a predetermined direction. The position indicator includes a reflection unit that reflects a part of the light projected from the transit fixing member and causes the return light to travel backward. The transit fixed body that has captured the return light calculates the displacement angle of the position indicator and the distance from the transit fixed body or a certain reference point to the position indicator with reference to a certain set azimuth. By the calculation in this transit fixed body, the distance to the target point can be measured quickly.

Recently, it has been considered to apply such a technique to the technical field for measuring the state quantity such as the length of the frame of the passenger conveyor, which is the object of the present invention.

The present invention has been made in view of the current state of the art of this kind described above, and the first purpose thereof is a passenger conveyor capable of measuring a state quantity related to a frame without using a measure or a piano wire. To provide a method for measuring a state quantity related to the frame.

A second object is an escalator equipped with a frame having a lower intersection and an upper intersection, and parts related to the frame ballast handrail installed near the lower intersection and the upper intersection are removed. Without
An object of the present invention is to provide a state quantity measuring method for a frame of a passenger conveyor, which can measure a state quantity for a frame.

A third object is to provide an escalator equipped with a frame having a lower intersection and an upper intersection, and even if it is difficult to determine the lower intersection and the upper intersection, the lower intersection and the upper intersection are calculated. Another object of the present invention is to provide a state quantity measuring method for a frame of a passenger conveyor, which can obtain the distance between the lower intersection and the upper intersection based on the obtained lower intersection and the upper intersection.

[0019]

In order to achieve the first object, there is provided a passenger conveyor having a balustrade and a frame supporting the balustrade, and a frame of the passenger conveyor for measuring a state quantity related to the frame. In such a state quantity measuring method, a position indicator having a first reflecting portion and a second reflecting portion that respectively reflect light, and a distal end portion arranged so as to come into contact with a portion of the frame, and an optical device having a computing function. By using a type surveying instrument, by projecting light from the optical surveying instrument to each of the first and second reflecting portions of the beam in a state where the position indicator is in contact with the frame, The position coordinates of each of the first and second reflecting portions are obtained, the position coordinates of the portion of the frame with which the position indicator is in contact are obtained based on these position coordinates, and the position of the portion of this frame is obtained. It is so as to obtain a state quantity relating to the frame from the target.

The present invention for obtaining the state quantity relating to the frame in this way is such that the optical surveying instrument projects light onto each of the first reflecting portion and the second reflecting portion of the position indicator. A triangle can be formed between the first reflecting portion and the second reflecting portion. Based on this triangle, calculation is performed by the optical surveying instrument, and the position coordinates of the first reflecting portion and the second reflecting portion are obtained. First reflection part or second
By setting the distance between the reflecting portion and the portion of the position indicator in contact with the frame with high accuracy in advance, the position coordinates of the portion of the position indicator in contact with the frame can be obtained. That is, the position coordinates of the part of the frame with which the position indicator is in contact can be obtained. For example, by obtaining corresponding position coordinates in a plurality of portions of the frame and obtaining a virtual straight line connecting these portions, it is possible to obtain the state quantity such as the length of the frame without using a measure or a piano wire.

Further, in order to achieve the above second object,
In particular, the passenger conveyor comprises an escalator, and the frame includes an upper chord member having a lower horizontal portion, an upper horizontal portion, and an inclined portion connecting the lower horizontal portion and the upper horizontal portion.

In such an escalator, for example, the position coordinate is brought into contact with the lower intersection point where the lower horizontal portion and the inclined portion intersect, and the position coordinate of the lower intersection point is determined by performing the measurement by the above-mentioned optical surveying instrument. Can be obtained, and at the upper intersection where the inclined part and the upper horizontal part intersect,
The position coordinates of the upper intersection can be obtained by bringing the position indicator into contact and performing the measurement by the above-described optical surveying instrument. The distance between the lower intersection and the upper intersection, that is, the length of the inclined portion of the frame can be determined from the obtained position coordinates of the lower intersection and the upper intersection. In such a measurement, it is only necessary to bring the position indicator into contact with the lower intersection and the upper intersection, and this work can be performed by removing only the balustrade. Therefore, it is arranged near the lower intersection and the upper intersection of the existing escalator. Measurements can be made without removing parts associated with the frame ballast handrail.

In order to achieve the second and third objects, the passenger conveyor comprises an escalator, and the frame includes a lower horizontal portion, an upper horizontal portion, and these lower horizontal portion and upper horizontal portion. By including the upper chord member having an inclined portion connecting the and, and by contacting the position indicator to a plurality of portions of the lower horizontal portion of the upper chord member, to obtain the respective position coordinates of the corresponding plurality of portions. , A first virtual straight line connecting these position coordinates is obtained based on these position coordinates, and the position indicator is provided at a plurality of parts of a part of the inclined part of the upper chord member located on the lower horizontal part side. By making contact with each other, the respective position coordinates of the corresponding plurality of parts are obtained, and based on these position coordinates, a second virtual straight line connecting these position coordinates is obtained, and the first virtual straight line and the second virtual line are obtained. From the straight line, the position coordinates of the lower intersection point where these virtual straight lines intersect are obtained, and the position indicator is brought into contact with a plurality of parts of the upper horizontal part side of the inclined part of the upper chord member. , The respective position coordinates of the corresponding plurality of parts are obtained, the third virtual straight line connecting these position coordinates is obtained based on these position coordinates, and the positions are provided at the plurality of parts of the upper horizontal part of the upper chord member. By contacting the indicator with each other, the respective position coordinates of the corresponding plurality of parts are obtained, and the fourth virtual straight line connecting these position coordinates is obtained based on these position coordinates, and the third virtual straight line and the third virtual straight line are connected. From the four virtual straight lines, the position coordinates of the upper intersection point where these virtual straight lines intersect are obtained, and based on the position coordinates of the lower intersection point and the position coordinates of the upper intersection point,
The length of the inclined portion of the upper chord member is determined.

In the present invention for obtaining the state quantity of the frame in this way, it suffices to bring the position indicator into contact with a site on the frame which is distant from the lower intersection or the upper intersection, and therefore, the lower intersection and the upper intersection of the existing escalator. The measurement can be performed without removing the parts related to the frame, ballast, and handrails that are located nearby, and without contacting the position indicator to the lower intersection and upper intersection where the corners are R-shaped. The position coordinates of the lower intersection and the position coordinates of the upper intersection can be determined by calculation. Based on the lower intersection and the upper intersection obtained by these calculations, the lower intersection,
The distance between the upper intersections, ie the length of the sloping part of the frame, can be determined.

It is a front view of the escalator which shows the state which installed the beam shown in FIG.

As shown in FIG. 1, the position indicator used in the first embodiment and the second embodiment described later, for example, the beam 3, is provided in the shape of a rod and has a first reflecting portion 3A for reflecting light. The second reflection portion 3B is provided, and the tip portion 3C arranged so as to come into contact with the site of the frame 1 is formed in a tapered shape. Note that, for example, the first reflecting portion 3A and the tip portion 3
The distance to C is preset to a highly accurate predetermined distance.

Further, an optical surveying instrument having an arithmetic function used in the first embodiment and a second embodiment described later, for example, a lightwave distance meter 5 shown in FIG. 2 is a known one.

The first embodiment and the second embodiment described later are applied to, for example, an escalator. As shown in FIG. 2, the escalator has a balustrade 2 as a main component.
And a frame 1 supporting the balustrade 2. As described above, the frame 1 includes the upper chord member 1a and the lower chord member 1b. For example, the upper chord member 1a includes the lower horizontal portion 4C, the upper horizontal portion 4D, and the lower horizontal portion 4C and the upper horizontal portion 4D. It has the inclined part 4E which connects.

Further, there is a lower intersection point C where the lower horizontal portion 4C and the inclined portion 4E intersect, and an upper intersection point D where the inclined portion 4E and the upper horizontal portion 4D intersect. Here, it is assumed that the balustrade 2 is renewed for the purpose of redesigning the design, and for this reason, the first embodiment is directed to the inclined portion 4E of the upper chord member 1a.
, The length of a straight line connecting the lower intersection C and the upper intersection D is taken as the state quantity of the frame 1 to be measured.

Further, for example, it is assumed that the corners of the lower intersection C and the upper intersection D are not deformed regardless of deterioration over time.

In such a situation, in the first embodiment, for example, first, the optical distance meter 5 is installed at the entrance / exit located above the lower horizontal portion 4C of the upper chord member 1a of the frame 1.
The tip portion 3C of the beam 3 is, for example, the upper chord member 1a of the frame 1
The lower intersection point C is contacted and the beam 3 is held so as not to move.

In this state, light is projected from the optical distance meter 5 toward each of the first reflecting portion 3A and the second reflecting portion 3B of the beam 3, and the respective reflected light is received by the optical distance measuring device 5.

As a result, the lightwave distance meter 5 and the first reflector 3
A triangle is formed between A and the second reflecting portion 3B. Based on this triangle, the lightwave rangefinder 5 performs a calculation for obtaining the position coordinates of the first reflecting portion 3A and the second reflecting portion 3B, for example, three-dimensional coordinates. Such calculation is known.

The first reflecting portion 3 obtained as described above

Similarly, an optical distance meter 5 is installed at the entrance / exit of the upper horizontal portion 4D of the upper chord member 1a of the frame 1 and the beam 3
The tip portion 3C of the beam 3 is brought into contact with the upper intersection D of the upper chord member 1a of the frame 1, for example, and the beam 3 is held so as not to move.

In this state, light is projected from the optical distance meter 5 toward each of the first reflecting portion 3A and the second reflecting portion 3B of the beam 3, and the respective reflected light is received by the optical distance meter 5.

The beam 3 is held so as not to move. Also on the side of the upper intersection D, the beam 3 is similarly held so as not to move.

In this first embodiment in which the length of the inclined portion 4E of the upper chord member 1a of the frame 1 is measured in this manner, the state quantity relating to the frame 1, that is, the inclined portion 4E of the frame 1 is measured without using a measure or a piano wire. Since it is possible to measure the length, it is possible to obtain the length of the inclined portion 4E within a relatively short time without the need for complicated manual installation work of a measure or piano wire and reading work of numerical values. Therefore, the measurement work efficiency can be improved. As a result, it is possible to shorten the renovation period of the balustrade 2. Further, the tip portion 3C of the beam 3 is properly arranged at the lower intersection C and the upper intersection D, and the beams 3 are held by the blocks 8A and 8B so as not to move.
As a result, there is no numerical reading error, which allows highly accurate measurement.

It is sufficient to remove only the balustrade panel 7 and bring the tip portion 3C of the beam 3 into contact with the lower intersection point C and the upper intersection point D of the upper chord member 1a. The parts related to the frame, ballast, and handrail do not have to be removed, which simplifies the work and also improves the work efficiency.

Further, since the tip portion 3C of the beam 3 is formed in a tapered shape, the target portion on the frame 1
That is, the tip 3C can be reliably brought into contact with the lower intersection C and the upper intersection d, which contributes to the realization of highly accurate measurement.

In the above description, the first reflecting portion 3A of the beam 3 is used.
The distance between the tip 3C and the tip 3C is set with high accuracy in advance, and the three-dimensional coordinates of the tip 3C, that is, the three-dimensional coordinates of the lower intersection C and the upper intersection D are set based on the obtained three-dimensional coordinates of the first reflecting portion 3A. The second reflecting portion 3A
And the tip portion 3C are set in advance, and the three-dimensional coordinates of the tip portion 3C, that is, the three-dimensional coordinates of the lower intersection point C and the upper intersection point D are obtained based on the obtained three-dimensional coordinates of the second reflecting portion 3B. You may
