In embodiment which concerns on this invention, it is a figure which shows a mode that the distance of the gap | interval between a step and a skirt guard is measured using the measurement adjustment jig.

  Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a diagram showing skirt guard portions 50 to 66 and steps 12 a to 12 h in the escalator 10. The escalator 10 is a device that moves passengers between a landing floor and a landing floor having a height difference. The escalator 10 includes skirt guard portions 50 to 66 and steps 12a to 12h. In addition to the skirt guard portions 50 to 66 and steps 12a to 12h, the escalator 10 includes components such as a moving handrail, an inner plate, a step chain, and a driving device, but detailed description thereof is omitted here.

  Steps 12a to 12h have such a size that one or two passengers can ride. When the escalator 10 is operating, the steps 12a to 12h move while maintaining a horizontal state with respect to the floor surface of the landing floor and the landing floor. Further, a plurality of grooves 13 (see FIG. 5) for preventing slipping are provided in steps 12a to 12h.

  The skirt guard portions 50 to 66 are erected on both sides in the longitudinal direction of the steps 12a to 12h so that the gaps between the steps 12a to 12h are a predetermined distance. And the skirt guard over the full length of the escalator 10 will be provided by connecting the adjacent skirt guard part mutually. The skirt guard portions 50 to 66 are attached by attachment portions described later. Then, as will be described later, by adjusting the attachment portion, the gap between the skirt guard portions 50 to 66 and the steps 12a to 12h can be adjusted to a predetermined distance.

  FIG. 2 is a view showing a state in which the vicinity of the skirt guard portions 52, 54, 56, and 58 among the skirt guards standing on the left side of steps 12a to 12h from the direction of arrow A in FIG. 3 is a cross-sectional view taken along line BB in FIG. As shown in FIGS. 2 and 3, the attachment portion 46a for attaching the skirt guard portion 52 and the skirt guard portion 54 on the upper side includes a first attachment member 32a, screws 85a and 86a, and a second attachment member 38a. And the fastening portion 76a.

  In the attachment part 46a for attaching the skirt guard part 52 and the skirt guard part 54 on the upper side, the skirt guard part 52 is fixed to the first attachment member 32a by screws 86a, and the skirt guard part 54 is attached to the first attachment member 32a by screws 85a. Fixed. The first attachment member 32a is attached to the second attachment member 38a by the fastening portion 76a. The hole through which the fastening portion 76a provided for attaching the first attachment member 32a and the second attachment member 38a has a substantially rectangular shape, loosens the fastening portion 76a and moves the first attachment member 32a to the left side or By sliding to the right (see FIG. 2), the skirt guard 52 and the gap 7 between the skirt guard 54 and the step 12a can be adjusted simultaneously.

  Since the attachment part 46b for attaching the skirt guard part 52 and the skirt guard part 54 on the lower side has the same configuration as the attachment part 46a, detailed description thereof is omitted. Note that the attachment portion 44a for attaching the skirt guard portion 54 and the skirt guard portion 56 and the attachment portion 42a for attaching the skirt guard portion 56 and the skirt guard portion 58 shown in FIG. 2 have the same configuration as the attachment portion 46a. Therefore, detailed description is omitted. As described above, the adjacent skirt guard portions are connected to each other by the corresponding attachment portions, so that the skirt guard is provided over almost the entire length of the escalator 10.

  As described above, the skirt guard portions 50 to 66 are arranged over the substantially entire length of the escalator 10 such that the gap 7 between the steps 12a to 12h is a predetermined distance. The gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h is deformed or displaced due to a passenger or the like using the escalator 10 hitting the skirt guard portions 50 to 66. May cause the distance of the gap 7 to change. Therefore, the distance of the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h is regularly measured and inspected in the maintenance management of the escalator 10, and is adjusted to be an appropriate distance of the gap 7. .

  Here, as a method for adjusting the distance of the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h, it is necessary to specify one step to be measured from the plurality of steps 12a to 12h. Here, the description will be made assuming that the step 12a is specified. When the maintenance worker adjusts the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h, the specified step 12a is moved between the landing floor and the landing floor, and the skirt guard portions 50 to 50 are moved. The gap 7 is adjusted by measuring the distance in the gap 7 between the plurality of skirt guard portions from 66. Here, the gap 7 between the step 12a and the skirt guard 52, the gap 7 between the step 12a and the skirt guard 56, the gap 7 between the step 12a and the skirt guard 60, and the step 12a and the skirt guard 64. The gaps 7 between the two are adjusted to an appropriate distance so that the distances are uniform.

  The measurement adjustment jig 100 measures the distance of the gap 7 between the skirt guard portions 50 to 66 and steps 12a to 12h, and adjusts the positional relationship between the skirt guard portions 50 to 66 and steps 12a to 12h. It is a jig. FIG. 4 is a perspective view of the measurement adjustment jig 100. FIG. 5 is a diagram illustrating a state in which the distance of the gap 7 between the step 12 a and the skirt guard 52 is measured using the measurement adjustment jig 100. The measurement adjustment jig 100 includes a main body part 110, an extending part 120, a recording part 130, a collar part 140, and an urging part 150.

  The main body 110 has a quadrangular prism shape that is fixedly fitted into the groove 13 of the step 12a that is the step to be measured. And the main-body part 110 has the main body side through-hole 112 penetrated along the longitudinal direction (arrow D direction of FIG. 5) of step 12a in the approximate center of the flat plate surface. Further, the main body 110 is formed with a main body side threaded portion 112 a on the outer periphery of the main body side through hole 112 for screwing with a body portion 130 b of the recording unit 130 described later.

  The extending portion 120 is an extending member that is inserted into the main body side through hole 112 of the main body portion 110 so as to be able to advance and retract. The cross-sectional area of the extending part 120 in the direction perpendicular to the extending direction (the direction of arrow D in FIG. 5) is slightly smaller than the hole area of the main body side through hole 112 of the main body part 110. The extending part 120 has a roller part 122 attached to the tip part (left side in FIG. 5) to contact the surface of the skirt guard parts 50 to 66 without being damaged. Here, the roller part 122 of the extending | stretching part 120 is attached in the state (state which can change an angle) which can rotate to the arrow C direction shown by FIG. 4 by making the axis | shaft 122a into a rotating shaft. Therefore, even if the step 12a is moved with the roller portion 122 of the extending portion 120 kept in contact with the surfaces of the skirt guard portions 50 to 66, the angle of the roller portion 122 can be changed following the moving direction of the step 12a. . The extending portion 120 adjusts the gap 7 by measuring the distance of the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h on the base end side (the right side in FIG. 5) opposite to the distal end portion. A scale 124 is provided for this purpose. Note that the cross-sectional area of the extending portion 120 in the direction perpendicular to the extending direction (the direction of arrow D in FIG. 5) is slightly smaller than the hole area of a recording-side through hole 132 of the recording unit 130 described later.

  The recording unit 130 includes a head 130a having a cross-sectional area (cross-sectional area in a direction perpendicular to the arrow D direction in FIG. 5) larger than the hole area of the main body side through hole 112 of the main body 110, and the main body side of the main body 110. A body portion 130b having an outer shape threaded to be screwed with the threaded portion 112a is included. Further, the recording unit 130 has a hole area larger than the cross-sectional area in the direction perpendicular to the extending direction (the arrow D direction in FIG. 5) among the cross-sectional areas of the extending unit 120, and the recording side through which the extending unit 120 is inserted A through hole 132 is formed. The relationship between the cross-sectional area and the hole area of the extending part 120, the recording part 130, and the main body part 110 is (cross-sectional area in a direction perpendicular to the extending direction of the extending part 120) <(the recording side through hole 132 of the recording part 130). Hole area) <(hole area of the main body side through hole 112 of the main body 110).

  The flange portion 140 is a flange member provided between the roller portion 122 and the main body portion 110 in the extending portion 120. The flange 140 has an outer shape in which the cross-sectional area in the direction perpendicular to the extending direction (arrow D direction in FIG. 5) is larger than the cross-sectional area in the direction perpendicular to the extending direction (arrow D direction in FIG. 5) of the extending part 120. have.

  The urging portion 150 is a spring member that urges the roller portion 122 provided at the distal end portion of the extending portion 120 and the surfaces of the skirt guard portions 50 to 66 in contact with each other. The urging portion 150 has one end attached to the left flat surface of the main body 110 and the other end attached to the right flat surface of the flange 140.

  The operation of the measurement adjustment jig 100 having the above configuration will be described with reference to FIGS. When the escalator 10 is used for a long period of time, the distance of the gap 7 changes due to the skirt guard portions 50 to 66 being deformed or displaced due to a passenger hitting the skirt guard portions 50 to 66 or the like. There is a case. Therefore, maintenance and inspection work for adjusting the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h is performed periodically. When the maintenance worker adjusts the gap 7 between the skirt guard portions 50 to 66 and the steps 12a to 12h, for example, the specified step 12a is moved between the landing floor and the landing floor, and the skirt There is a maintenance and inspection method in which the gap 7 is adjusted by measuring the distance in the gap 7 between the plurality of skirt guards specified from among the guard portions 50 to 66. Here, the gap 7 between the step 12a and the skirt guard 52, the gap 7 between the step 12a and the skirt guard 56, the gap 7 between the step 12a and the skirt guard 60, and the step 12a and the skirt guard 64. A maintenance and inspection operation for adjusting the gaps 7 to be appropriate distances and making the distances uniform will be described.

  Specifically, the maintenance worker fits and fixes the main body 110 in the groove 13 of step 12a in the maintenance adjustment jig 100. For example, as shown in FIG. 5, the third groove 13 from the left side is fixed. Fit into. Then, the distance of the gap 7 between the skirt guard 52 and the step 12a is measured. Specifically, the maintenance worker measures the gap 7 between the skirt guard 52 and the step 12a with a ruler or the like, and the gap 7 is a predetermined distance (for example, 1.5 mm to 2 mm). Confirm that 0 mm is within the allowable range).

  When the gap 7 between the skirt guard 52 and the step 12a is, for example, 2.0 mm, the distance between the skirt guard 52 and the step 12a is within a predetermined range. , The measured value (2.0 mm) measured as described above is recorded to be a reference value for adjusting the gap between the skirt guard portions 56, 60, 64 and step 12a. Specifically, the maintenance worker moves the right end surface of the head 130a of the recording unit 130 to a position corresponding to the measurement value (2.0 mm) on the scale unit 124 (in other words, the head of the recording unit 130). The right end surface of the portion 130a is set to coincide with the position indicating 2.0 mm on the scale portion 124). In addition, when the distance of the gap 7 between the skirt guard 52 and the step 12a is out of 1.5 mm to 2.0 mm, the first mounting members 32a and 32b of the mounting portions 46a and 46b are slid. Thus, the distance of the gap 7 between the skirt guard 52 and the step 12a is adjusted so as to fall within the range of 1.5 mm to 2.0 mm, and the adjusted gap 7 is measured again using a ruler or the like. Then, the maintenance worker moves the right end surface of the head portion 130a of the recording unit 130 to a position corresponding to the adjusted measurement value (for example, 2.0 mm) on the scale unit 124. In the following description, it is assumed that the distance (measured value) of the gap 7 between the step 12a and the skirt guard 52 is 2.0 mm.

  Subsequently, the maintenance worker moves step 12a to the position of the skirt guard portion 56 which is the next measurement location. Here, if the position of the skirt guard 56 is deviated from the normal time, the gap 7 between the skirt guard 56 and the step 12a changes. For example, when the gap 7 between the skirt guard portion 56 and the step 12 a is large, the extending portion 122 is moved until the roller portion 122 comes into contact with the surface of the skirt guard portion 56 by the urging force of the urging portion 150. It will move in the direction of arrow D. As described above, in order to set the measured value of the gap 7 between the skirt guard 52 and the step 12a as the reference value for the gap adjustment, the position where the right end surface of the head 130a indicates 2.0 mm on the scale portion 124. However, since the gap 7 is large, the position of the right end surface of the head portion 130a of the recording unit 130 on the scale unit 124 matches 2.6 mm on the scale unit 124, for example. As described above, the gap 7 between the skirt guard portion 56 and the step 12a becomes larger (here, 0.6 mm). Therefore, in order to adjust the gap 7 between the skirt guard portion 56 and the step 12a, the attachment portion 42a until the right end surface of the head portion 130a coincides with the position indicating 2.0 mm on the scale portion 124. , 44a, etc. are adjusted. Thereby, the distance of the gap 7 between the skirt guard 52 and the step 12a and the distance of the gap 7 between the skirt guard 56 and the step 12a can be made uniform.

  When the gap 7 between the skirt guard 56 and the step 12a is small, the position of the right end surface of the head portion 130a of the recording unit 130 on the scale unit 124 is, for example, 1.3 mm on the scale unit 124. As a result, the gap 7 between the skirt guard 56 and the step 12a is deviated by a small amount (0.7 mm in this case). Also in this case, in order to adjust the gap 7 between the skirt guard portion 56 and the step 12a, the attachment portions 42a, until the right end surface of the head portion 130a coincides with the position indicating 2.0 mm on the scale portion 124. 44a and the like are adjusted. Thereby, the distance of the gap 7 between the skirt guard 52 and the step 12a and the distance of the gap 7 between the skirt guard 56 and the step 12a can be made uniform.

  Next, the maintenance worker moves the step 12a to the position of the skirt guard 60 which is the next measurement location, measures the distance of the gap 7 between the skirt guard 60 and the step 12a, and is the same as the above adjustment method. Further, the distance of the gap 7 between the skirt guard 52 and the step 12a is adjusted to be uniform. Subsequently, the maintenance worker moves the step 12a to the position of the skirt guard 64, which is the next measurement location, measures the distance of the gap 7 between the skirt guard 64 and the step 12a, and is the same as the adjustment method described above. Further, the distance of the gap 7 between the skirt guard 52 and the step 12a is adjusted to be uniform.

  As described above, the maintenance worker measures the gap 7 between the plurality of skirt guard portions 52, 56, 60, and 64 in the step 12 a to be measured, and the step 12 a and the skirt guard portions 52, 56, and 60 are measured. , 64, the gap 7 between the step 12a and the skirt guard 52 is a distance within a predetermined range corresponding to the measured value on the scale portion 124. The right end surface of the head 130a of the recording unit 130 is moved to the position. Further, when the gap 7 is out of a predetermined range, the positional relationship between the step 12a and the skirt guard 52 is adjusted to correspond to the measured value after the adjustment on the scale portion 124. The right end surface of the head 130a of the recording unit 130 is moved to the position where the recording is performed. Thereafter, while moving the step 12a, the distance of the gap 7 between the step 12a and the skirt guard portions 56, 60, 64 is equal to the gap 7 between the step 12 of the measurement adjusting jig 100 and the skirt guard 52. Each can be adjusted to be uniform with the distance measurement. As a result, the distance of the gap 7 between the step 12a and the skirt guards 52, 56, 60, 64 is within a predetermined range (for example, an allowable range is 1.5 mm to 2.0 mm). Furthermore, the gaps 7 can be made to have a uniform distance.

  Note that the biasing portion 150 of the measurement adjusting jig 100 is biased in the direction in which the roller portion 122 provided at the distal end portion of the extending portion 120 and the surfaces of the skirt guard portions 50 to 66 come into contact with each other. The end is attached to the left flat surface of the main body 110 and the other end is attached to the right flat surface of the flange 140. However, one end is attached to the left flat surface of the main body 110 and the other end is extended. The part 120 may be attached to a part between the roller part 122 and the main body part 110.

  Moreover, although the said measurement adjustment jig 100 demonstrated as what has the main-body part 110 engage | inserted in the groove part 13 of step 12a to be measured, the main-body part 110 is engage | inserted in the groove part which comprises the riser of step 12a to be measured. The gap 7 between the step 12a and the skirt guard portions 50 to 66 can be measured and adjusted in the same manner even if the shape is a shape to be adjusted.
