Description

  The present invention relates to an elevator hoistway dimension measuring apparatus.

  For the purpose of dealing with the aging of elevators and improving the performance and function of elevators, existing elevators called refurbishment or modernization are often updated.

  In the renovation and renewal of the rope type elevator, the existing structure (frame) of the guide rail and hoistway, including the entrance / exit structure at the landing on each floor, is used as it is, and the car that moves in the hoistway, the hoisting mechanism, or control There are many cases where a panel is replaced.

  In such renovation and renewal of existing elevators, unlike the installation of elevators for new buildings, the landing door mechanism on each floor uses the state already built in the hoistway, so new A hoistway in consideration of the position of the existing landing door mechanism in order to carry a car etc. into the hoistway and install it so that an appropriate position interval can be obtained without any hindrance between the landing doorway on each floor. Dimensional measurements are required again.

  By the way, the existing landing door mechanism at each floor entrance has a sill (sill) that guides the landing door so that it protrudes into the hoistway. Therefore, in the hoistway dimension measurement, the sill position is taken into account. Is required.

  Conventionally, in elevator hoistway dimension measurement work that has been done for renovation and renewal, for example, one worker stood at the entrance of the landing with a tape measure and another worker who got down to the pit in the hoistway, The tip part (claw part) of the measuring part of the tape measure was pulled out and applied to the rear wall surface to be measured, and the worker on the entrance side read the scale of the measuring part located at the sill edge.

  The same applies to the left and right side walls in the hoistway. The worker at the entrance / exit side of the hall sets the position with the edge of the sill as the measurement standard, and the claw part of the tape measure pulled out by another worker is on the left and right The distance (dimension) between the left and right walls was obtained from the sum of the scale values at the measured reference position.

  In conventional elevator hoistway dimension measurement, the tape measure measure part is pulled out and the distance is read, so the pull out measure part is slack or the pulling direction is not perpendicular to the wall surface and the angle is shifted. In such a case, an error occurs in the measured value.

  Therefore, in the past, in order to increase the measurement accuracy as much as possible, an L-shaped tape measure (Kanejakaku) was applied to the threshold part on the sill side and the wall surface side against the ruler part passed between the two points. The angle was also confirmed.

  In general, in measuring a linear distance between two points, a so-called laser distance meter that obtains a distance from time measurement between transmission and reception to a measurement object of a transmission pulse laser beam can be used in addition to a tape measure.

  Laser rangefinders can measure distances with good linearity, so that good distance measurement accuracy can be obtained, but the device itself has a built-in computer and a complicated configuration that incorporates an arithmetic processing function. Requires considerable skill. In addition, as the hoistway dimension measurement in the existing elevator, the sill of the landing door, which is the measurement reference position and the installation location of the measurement equipment, is structurally attached so as to protrude into the hoistway. In the laser rangefinder that measures the distance by installing it at the center, it is inconvenient to measure the horizontal dimension of the hoistway at the same time, apart from the distance measurement in the depth direction of the hoistway.

Note that the distance between two points in the horizontal direction is not measured with a tape measure as in the hoistway dimension measurement, but a measuring tool that integrates a laser irradiator and a tape measure and measures the distance in the vertical direction is provided. Proposed.
JP-A-2001-255042

  In any case, when measuring the hoistway dimensions of an elevator using a conventional tape measure, pull out the measure part of the tape measure as the measuring means, apply the claw part at the tip to the inner wall surface of the hoistway, Since the linearity, the angle with respect to the wall surface, and the like were measured, there was a problem that even if the music scale was operated, the operation was complicated and the measurement accuracy was unavoidable.

  Accordingly, the present invention has been made to solve the above problems, and provides an elevator hoistway dimension measuring apparatus that can easily and accurately measure the dimensions to the hoistway wall with a simple configuration. With the goal.

  In order to achieve the above object, the present invention is an elevator hoistway dimension measuring device that is attached to a sill for a landing door and measures the distance to the inner wall surface of the hoistway, and is configured to be detachable from the sill.

  As described above, the hoistway dimension measuring apparatus according to the present invention is configured such that the light irradiator and the measuring means are installed on a pedestal that is detachable from the sill for the landing door, and the ruler portion of the measuring means is irradiated linearly. Therefore, the distance (dimension) by the measuring means from the sill position to the wall surface of the hoistway can be easily and accurately measured with a simple configuration.

Hereinafter, an embodiment of an elevator hoistway dimension measuring apparatus according to the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an embodiment of an elevator hoistway dimension measuring apparatus according to the present invention. FIG. 1 is a front view of a state in which the hoistway dimension measuring apparatus is attached to a sill for a landing door as seen from the hoistway side. 2 is a plan view of the main part of FIG. 1, FIG. 3 is a right side view of the arrow direction from the AA line in FIG. 1, and FIG. 4 is a main part plan of the arrow direction from the BB line in FIG. FIG.

  There are two types of landing doors at the entrance of an elevator, that is, a double door type that is guided by two sill grooves and a central door type that is guided by one sill groove even with the same side sliding door. However, in this embodiment, description will be made assuming that the hoistway dimension measuring device is attached to a sill for opening two doors guided by two sill grooves.

  As shown in FIGS. 1 and 3, a pair of anchor bolts 21, 21 are driven into the housing wall 2 in advance in order to fix the sill 1 for landing door guidance to the housing wall 2 facing the inside of the hoistway. It is.

As shown in FIG. 1, the anchor bolts 21 and 21 are fitted through the elongated holes 3 a of the brackets 3 and 3 having a L-shaped cross section, and are fastened and fixed by nuts 22.
As shown in FIG. 1 or 3, the long sill receiving portion 4 for supporting the sill 1 includes a bolt 51 penetrating the long hole 3 b of the brackets 3, 3 and the long hole 4 a of the sill receiving portion 4. It is fixed with a nut 52.

As shown in FIGS. 1 and 3, the sill 1 brought into close contact with the end surface of the landing floor 6 is placed on the sill receiving part 4 and fixed to the sill receiving part 4 by bolts 71 and nuts 72. Yes.
As shown in FIGS. 2 to 4, the sill 1 of this embodiment has two sill grooves 1 a and 1 b with a concavo-convex longitudinal section, but the sill 1 and the sill receiving portion. Since the bolt 71 for fastening 4 is positioned at the convex portion between the two sill grooves 1 a and 1 b, the bolt 71 is inserted into the hollow on the upper portion of the convex portion and screwed into the nut 72.

  Further, the sill 1 is manufactured by extruding aluminum material, and at the bottom of the two sill grooves 1a and 1b formed, as shown by broken lines in FIGS. 2 and 4, the sill grooves 1a and 1b are formed. Long holes 1aa and 1ba for dropping the accumulated dust downward are appropriately formed, and although not shown, bolt holes are formed in the threshold receiving portion 4 at positions corresponding to the long holes 1aa and 1ba. .

  As shown in FIGS. 1 to 4, the hoistway dimension measuring apparatus 8 of this embodiment has a pedestal 81 configured to be detachable on the sill 1, and the pedestal 81 is detachably fixed to the sill 1. A plate-like base 811 and a rectangular slide plate 812 which is on the base 811 and is slidable in a horizontal plane as shown in particular in FIG. ing.

  On the slide plate 812 of the pedestal 81, as shown in FIGS. 1 to 3, a tape measure 82 as a measuring means and a laser irradiator 83 as a light irradiator are installed, and FIGS. As shown in FIG. 4, the tilt position of the base 811 attached to the sill 1 at four locations of the base 811 can be adjusted. In other words, the base 811 is provided with an angle adjustment mechanism 84 serving as a so-called jack bolt so that the inclination angle of the laser beam irradiation direction with respect to the horizontal plane by the laser irradiator 83 mounted on the slide plate 812 can be adjusted. Yes. As the laser irradiator 83 of this embodiment, a commercially available handy type laser irradiator can be adopted.

  The base 811 of the pedestal 81 is fixed to the sill 1 and the sill receiving part 4 by so-called grip bolts 813 shown in FIGS.

  That is, as shown in FIGS. 2 and 4, the base 811 is formed with a long hole 811A, and the grip bolt 813 through the long hole 811A is connected to the long holes 1aa and 1ba of the sill 1, and not shown. The bolt hole of the sill receiving part 4 is penetrated and the tip part of the grip bolt 813 is passed through the pin 813a, and the sill receiving part 4 is locked. In this state, the base 811 can be fixed to the sill 1 and the sill receiving portion 4 by tightening the nut 814 screwed to the grip bolt 813 (see FIGS. 1 to 4).

As shown in FIG. 4, the slide plate 812 is formed with a pedestal through hole 812a having a long slit shape along the longitudinal direction thereof.
Since the bolt 815 that is loosely inserted into the base through hole 812a of the slide plate 812 and penetrates the base 811 is screwed into the wing nut 815a, the base 811 and the slide plate 812 are connected via the bolt 815. Is pivoted.

  Accordingly, the slide plate 812 can slide on the base 811 and change its position and orientation while the base through-hole 812a is restrained by the bolt 815 by the fitting / removing operation of the butterfly nut 815a with respect to the bolt 815. By sliding the nut 815a, the slide plate 812 can be fixed to the base 811 at an arbitrary position and orientation (see FIGS. 1, 3 and 4).

  4, in the state shown in FIG. 1, one side of the rectangular base 811 on the hoistway side is attached so as to be parallel to the longitudinal direction of the sill 1. At the same time, when the slide plate 812 is fixed on the base 811, it is attached so that the longitudinal direction of the base through-hole 812 a is orthogonal to the longitudinal direction of the sill 1 (that is, the one side of the base 811). .

  As shown in FIGS. 1 to 4, stoppers 811 a and 811 b are planted on the edge of the base 811 on the hoistway side. Therefore, the wing nut 815 a of the bolt 815 is loosened, and the slide plate 812 is shown in FIG. When moved along the pedestal through hole 812a from the position shown in FIGS. 1 to 4 and rotated 90 degrees to the right and left, the slide plate 812 comes into contact with the stoppers 811a and 811b, respectively, and the mounted laser irradiation The direction of the container 83 and the tape measure (measuring means) 82 can be made to coincide with the longitudinal direction of the sill 1, that is, the direction orthogonal to the left and right inner wall surfaces of the hoistway.

  Further, as shown in FIG. 1 to FIG. 4, since the level 85 is screwed to the rear upper surface of the base 811, an operator can look at the level 85 and use a plurality of jack bolts. By adjusting the angle adjusting mechanism 84, the inclination angle of the base 811 with respect to the horizontal plane is adjusted, and the orientation of the laser irradiator 83 and the tape measure 82 mounted on the slide plate 812 is set to be horizontal. be able to.

Next, as shown in FIG. 1, a box-shaped mounting base 8121 for mounting the laser irradiator 83 is fixed on the upper surface of the slide plate 812.
As shown in FIGS. 1 to 3, the laser irradiator 83 placed on the mount 8121 is covered with a U-shaped fixture 8122 that is screwed to the mount 8121 while covering the laser irradiator 83. It is fixed.

  As shown in FIG. 3, a protrusion 8121a is planted at the rear end of the mounting base 8121 so that the mounted laser irradiator 83 does not move backward and drop off. The fall prevention locking portion 83a provided in the laser irradiator 83 is configured to be locked to the protrusion 8121a. Therefore, the laser irradiator 83 is fixed on the mounting base 8121 in a state where the fall prevention locking portion 83a is locked to the protrusion 8121a.

  Next, on the upper surface of the fixture 8122 to which the laser irradiator 83 is fixed, as shown in FIG. 1 to FIG. It is attached with folding claws 8123a and 8123a, and the tape measure 82 is accommodated in this U-shape. Of course, the tape measure 82 is housed in the tape measure fixture 8123 in such a direction that the drawing direction of the ruler 82a coincides with the laser beam irradiation direction of the laser irradiator 83.

  And since the belt 8124 is spanned so as to cover the upper part of the tape measure 82 and pass between the folded claws 8123a and 8123a of the tape measure fixture 8123, the tape measure 82 is stable in a state of being fitted into the tape measure fixture 8123. . The belt 8124 is preferably formed of a stretchable material such as a rubber member so that the tape measure 82 can be fixed more stably.

  As shown in FIG. 2, a claw portion 82b is integrally provided at the front end portion of the measure portion 82a drawn from the tape measure 82. In this embodiment, when the claw portion 82b is pulled out in a straight line in the horizontal direction. As shown in an enlarged view in FIG. 5, the tape measure 82 and the laser are formed so that a distance of a predetermined distance d is formed between the center position P of the opening of the laser irradiator 83 and the lower end of the claw portion 82b. The height position between the irradiator 83 is set.

  Further, on the rectangular base 811 constituting the pedestal 81, the angle adjusting mechanism 84 formed of a so-called jack bolt is screwed into the four locations corresponding to the upper surface (convex portion) of the sill 1 as described above. Therefore, the operator operates the angle adjustment mechanism 84 at each position while looking at the level 85 to adjust the height position of the base 811, and the irradiation direction by the base 81, that is, the laser irradiator 83 is changed. The laser beam can be irradiated perpendicularly to the inner wall surface of the hoistway to be distance-measured without being deviated from the horizontal plane.

In this embodiment, as shown in FIGS. 1 to 3, a guide portion 86 that is entirely long and has an inverted U shape is detachably attached to a base 811 of a base 81.
Since the guide portion 86 is screwed to the base 811 on both sides in the longitudinal direction, the edge (the sill side) of the tip portion bent downward is brought into contact with the edge on the hoistway side of the sill 1, In the center portion, at a position intersecting with the ruler portion 82 a drawn from the tape measure 82, the guide portion 86 is perpendicular to the ruler portion 82 a and indicates the line position of the edge of the sill 1.

  Therefore, the worker draws out the ruler 82a of the tape measure 82 in a straight line and reads the scale of the ruler 82a intersecting with the guide 86 while the claw 82b is in contact with the inner wall of the hoistway. It is possible to accurately measure the distance (dimension) from one to the corresponding hoistway wall.

  In this embodiment, the guide portion 86 is attached to the base 811 so as to be passed between the laser irradiator 83 and the measure portion 82a drawn from the tape measure (measuring means) 82. When the wing nut 815a is loosened and the slide plate 812 is rotated, it collides with the tape measure 82 protruding upward. Therefore, as will be described below, when the slide plate 812 is slid and rotated to measure the distance to the left and right wall surfaces of the hoistway, the guide portion 86 is once removed from the base 811 and then the slide plate 812 is removed. , And the direction of the slide plate 812 (that is, the direction of the tape measure 82 and the laser irradiator 83) is made to coincide with the longitudinal direction of the sill 1, and then the guide portion 86 is fixed to the base 811 again.

  1 to 4, the slide plate 812 fixed to the base 811 is positioned so that the longitudinal direction of the base through-hole 812a is orthogonal to the longitudinal direction of the sill 1, so that the direction of the slide plate 812 passes through the base. The laser irradiator 83 that coincides with the longitudinal direction of the hole 812a irradiates the laser beam perpendicularly to the back wall of the hoistway, and the tape measure 82 is linearly along the irradiated linear laser beam locus. The ruler 82a can be pulled out to the back wall.

The hoistway dimension measuring method by the elevator hoistway dimension measuring apparatus in this embodiment installed on the sill 1 with the above configuration will be described.
First, in measuring the distance (dimension) in the depth direction of the hoistway, after adjusting the direction of the slide plate 812 by adjusting the tightening of the wing nut 814, the operator looks at the level 85 and looks at the pedestal. After confirming that 81 is horizontal or making an adjustment so as to form a horizontal plane, the laser irradiator 83 is activated to irradiate the laser beam toward the depth wall surface of the hoistway to be measured. The irradiation direction of the laser light is perpendicular to the wall surface of the hoistway, a bright beam spot is drawn on the wall surface, and the light trace length indicates the shortest distance.

  Next, the operator pulls out the claw portion 82b of the measuring tape 82, which is a measuring means, in a straight line in a state where the laser beam is appropriately irradiated toward the hoistway wall surface, and pulls the claw portion 82b on the wall surface of the laser light. It is positioned at the beam spot that is the irradiation position.

  At this time, similarly to the positional relationship shown in FIG. 5, that is, a distance of a constant distance d is formed between the center position P of the opening of the laser irradiator 83 and the lower end of the claw portion 82b, FIG. As shown, the claw portion 82b is applied so that a constant distance d is similarly obtained between the laser beam spot S and the lower end of the claw portion 82b in contact with the wall surface thereof. Thereby, distance (dimension) measurement can be performed more accurately.

  In FIG. 6, when the claw portion 82b of the tape measure 82 is brought into contact with the hoistway wall surface, the interval (constant interval d) between the beam spot S and the claw portion 82b is set easily and reliably. Fig. 9 shows a state in which the aiming plate 82c is attached and fixed to the claw portion 82b in advance. In FIG. 6, the aiming hole 82ca is formed at the position of the aiming plate 82c to be irradiated with the beam spot S (the position at a constant interval d from the lower end of the claw portion 82). If the contact can be made, it is not always necessary to open the hole (sighting hole 82ca).

  Next, the direction of the laser irradiator 83 and the tape measure 82 is changed by a combination of the loosening and tightening operations of the wing nut 815a and the sliding and rotating operations of the slide plate 812 to change the distance between the left and right walls of the hoistway ( 1 to FIG. 1, which are cross-sectional views taken along the line B-B in FIGS. 1 and 1. FIG. 7 to FIG. 9, and FIG. 10 and FIG. The description will be given with reference.

  First, the worker removes the guide portion 86 from the base 811 of the base 81, loosens the wing nut 815a, and moves (slides) the slide plate 812 in the direction of the arrow Y as shown in FIG. Transition to the state shown in.

  Next, in the state of FIG. 8, the slide plate 812 is rotated in the direction of the arrow R shown in FIG. 9 to the position shown in FIG. 9, and the slide plate 812 is moved (slid) in the direction of the arrow X. Comes into contact with the stopper 811b, and its direction is parallel to the direction of the sill 1, as shown in the plan view of the main part of FIG. In this state, the wing nut 815 a shown in FIG. 1 is tightened, and the slide plate 812 is fixed to the base 811.

  After that, the guide part 86 is attached to the base 811 as shown in FIG. 10, and the laser irradiation toward the inner wall of the hoistway in the right direction in the figure is performed in the same procedure as the distance measurement in the hoistway depth direction described above. The distance to the wall surface in the right direction in the figure at this position is measured by the irradiation of the laser beam by the device 83 and the operation of the tape measure 82.

  As shown in FIG. 10, the reference line 86a to be the distance measurement reference position is drawn on the guide part 86 in advance by marking or the like so as to be convenient for the reading operation of the ruler part 82a in the distance measurement. It is good to add.

  Although detailed description is omitted, the distance measurement to the left wall surface in the figure is also performed by bringing the slide plate 812 into contact with the stopper 811a as shown in FIG. Accurate distance measurement is possible.

  In this way, the dimension in the width direction of the hoistway can be easily and accurately obtained from the sum of the distance measurement values to the left and right side walls of the hoistway with the reference line 86a of the guide portion 86 as the measurement reference position.

  In the description of the above embodiment, the guide portion 86 attached to the base 811 has the edge line on the landing side (the sill side) of the guide portion 86 as shown in the plan view of the main part of FIG. Thus, the operator can accurately read the scale of the ruler 82a of the tape measure 82 by matching the line of the hoistway side with the vertical line.

  Therefore, for example, the shape and size of the sill 1 may vary depending on the type of the door opening direction of the landing door, and the edge line on the landing side (the sill side) of the guide portion 86 is moved up and down the sill 1 due to the mounting structure. When it is not possible to match the edge line on the road side in the vertical direction, as shown in FIG. 12, a cut line 86b that matches the edge line on the hoistway side of the sill 1 is formed in the guide portion 86 in advance. It is good to keep.

  In the above description, the tape measure 82 as the measuring means has been described as adopting an analog type so that the scale 82a is pulled out to read the scale, but instead of an analog type tape measure, it has recently been commercially available. A digital tape measure can also be used.

  In the above embodiment, the light irradiator is described as irradiating a laser beam. However, in order to assist the proper operation of pulling out the ruler 82a, it is possible to irradiate a light beam with a small diameter in a straight line. Any irradiator can be used. Therefore, although it is actually desirable to be a laser irradiator, the irradiator is not limited to laser light, for example, as long as it is an irradiator that can output light with a thin linear beam diameter that can indicate the direction in which the measure 82a is drawn. Any other visible light may be used as long as it can irradiate light that allows the worker to recognize the light trace with the eyes.

  As described above, according to the elevator hoistway dimension measuring apparatus of the present invention, the light irradiator and the measuring means are mounted and installed so that the drawing direction of the ruler unit and the light irradiation direction are common. By a simple calibration operation, highly accurate distance (dimension) measurement with few errors can be easily performed.
