Embodiment 1 FIG.
First, the structure of the escalator will be described with reference to FIGS. FIG. 1 is a side view showing the structure of an escalator.

  1 is an escalator truss. The truss 1 is composed of a structure that supports the weight of the escalator and the load. An angle member 2 is provided at the upper end of the truss 1. The angle member 2 is made of an L-shaped member in a side view. A part of the angle member 2 extends in the vertical direction and is fixed to the end surface of the upper end portion of the truss 1. The other part of the angle member 2 protrudes in the horizontal direction from the upper end of the truss 1 so as to further extend in the longitudinal direction of the truss 1. The other part of the angle member 2 is placed on and supported by the fixed body 3 on the building side on the upper floor (for example, the second floor).

  An angle member 4 is provided at the lower end of the truss 1. The angle member 4 is made of an L-shaped member when viewed from the side. A part of the angle member 4 extends in the vertical direction and is fixed to the end surface of the lower end portion of the truss 1. The other part of the angle member 4 projects in the horizontal direction from the lower end of the truss 1 so as to further extend in the longitudinal direction of the truss 1. The other part of the angle member 4 is placed and supported from above on the fixed body 5 on the building side on the lower floor (for example, the first floor).

  The angle member 2 is supported by the fixed body 3 and the angle member 4 is supported by the fixed body 5, whereby the truss 1 is spanned between the upper and lower floors. Moreover, as shown in FIG. 1, the intermediate | middle inclination part of the truss 1 is also supported by the fixed body by the side of a building as needed.

  6 is a step on which the passenger of the escalator rides when moving between the upper and lower floors. A number of steps 6 are connected to the endless step chain 7. The step chain 7 is wound around the sprocket 9 in the upper machine room 8. The step chain 7 is wound around the sprocket 11 in the lower machine room 10.

  Reference numeral 12 denotes a moving handrail for a passenger who gets on and off the step 6 or a passenger on the step 6 to grab. The moving handrail 12 has an endless shape. The moving handrail 12 is driven to synchronize with the step 6. The motor 13 includes a driving device that drives the step 6 and the moving handrail 12. The motor 13 is installed in the upper machine room 8.

  In the upper machine room 8, a control panel 14 is provided in addition to the sprocket 9 and the motor 13. The control panel 14 controls the operation of the escalator. For example, the motor 13 is controlled by the control panel 14.

  FIG. 2 is an enlarged view of part A shown in FIG. In FIG. 2, H steel 3 a is shown as an example of the fixed body 3. FIG. 3 is an enlarged view of part B shown in FIG. In FIG. 3, H steel 5 a is shown as an example of the fixed body 5.

  The upper angle member 2 is placed and fixed on the upper surface of the H steel 3a via the bearing plate 15a and the liner 16a. The bearing plate 15a is a cradle fixed to the fixed body 3 on the building side. The bearing plate 15a is made of, for example, a metal plate member.

The liner 16a is provided on the upper surface of the bearing plate 15a in order to adjust the height of the angle member 2 (that is, the height of the upper end portion of the truss 1). The liner 16a is made of, for example, a thin plate member made of metal, and a plurality of the liners 16a are arranged to overlap each other. By appropriately providing the liner 16a on the bearing plate 15a, the truss 1 is horizontally disposed at a predetermined height.
L <b> 1 shown in FIG. 2 indicates the cost of the angle member 2.

  The lower angle member 4 is placed and fixed on the upper surface of the H steel 5a via the bearing plate 15b and the liner 16b. The bearing plate 15b has the same configuration and function as the bearing plate 15a. The liner 16b has the same configuration and function as the liner 16a. L <b> 2 shown in FIG. 3 indicates the cost of the angle member 4.

  Since the support structure on the upper side and the support structure on the lower side of the escalator are the same, only the angle member 2 will be specifically described below, and the description on the angle member 4 will be omitted.

  FIG. 4 is a perspective view showing another example of the A part. In FIG. 4, the concrete fixed body 3 is shown. When the fixed body 3 is made of concrete, the bearing plate 15 a is fixed to the fixed body 3 using, for example, anchor bolts 17. Even in such a case, the angle member 2 is supported by the fixed body 3 via the bearing plate 15a and the liner 16a. Reference numeral 18 shown in FIG. 4 is a stopper for determining the position of the angle member 2 (truss 1).

  FIG. 5 is a side view showing various states of the A portion. As shown in FIG. 2, the bearing plate 15a and the liner 16a are preferably arranged and fixed so that the end of the truss 1 side coincides with the end of the H steel 3a on the truss 1 side. However, at the actual installation site of the escalator, as shown in FIGS. 5A to 5H, the end of the bearing plate 15a protrudes toward the truss 1 from the end of the H steel 3a or the liner 16a. An edge part protrudes from the edge part of H steel 3a to the truss 1 side. Further, the end of the bearing plate 15a is arranged at a position away from the truss 1 from the end of the H steel 3a, or the end of the liner 16a is arranged at a position away from the truss 1 from the end of the H steel 3a. Or

  The dimension of the angle member 2, the dimension of the bearing plate 15a, and the dimension of the liner 16a are known. For this reason, for example, when installing the escalator, if the installation state of the angle member 2 can be confirmed from above, the cost of the angle member 2 can be easily measured. However, in the escalator already installed in the building, the upper side of the angle member 2 is finished as the floor of the upper floor. For this reason, in the existing escalator, the installation state of the angle member 2 cannot be confirmed from above.

  In the following, the configuration of the apparatus for measuring the cost of the angle member 2 (and 4) will be specifically described with reference to FIGS.

  FIG. 6 is a diagram showing an escalator turnover measuring apparatus according to Embodiment 1 of the present invention. FIG. 6A shows a front view of the bar allowance measuring device. FIG. 6B shows a left side view of the bar allowance measuring apparatus. FIG.6 (c) has shown the right view of the principal part of a bar allowance measuring apparatus. 7 is a cross-sectional view taken along the line CC shown in FIG. 8 is a cross-sectional view taken along the line DD shown in FIG.

  The principal part of the bar allowance measuring apparatus according to the present embodiment includes, for example, a tube body 19, an operating rod 20, an elastic body 21, a backing plate 22, a first mounting portion 23, and a second mounting portion 24.

The tube body 19 is formed of a tubular member that is bent so that one end thereof has an L shape.
The tubular body 19 includes, for example, a base portion 19a, a distal end portion 19b, and a bending portion 19c. The base portion 19a has a linear shape and has a predetermined length. The tip 19b is linear and has a predetermined length shorter than the base 19a. The distal end portion 19b is disposed so as to be orthogonal to the base portion 19a. The bending part 19c consists of a part which connects the base part 19a and the front-end | tip part 19b. Since the tubular body 19 is a tubular member, the hollow portion of the base portion 19a, the hollow portion of the curved portion 19c, and the hollow portion of the distal end portion 19b are formed continuously.

  The operation rod 20 is a cylindrical rod-shaped member having a predetermined length. One end of the operation rod 20 is disposed in the internal space of the tube body 19 (the hollow portion of the base portion 19a). The other end portion side of the operation rod 20 is disposed so as to protrude from one end surface of the tube body 19 (end surface of the base portion 19a). The operation rod 20 is arranged in a straight line with respect to the base portion 19 a of the tube body 19. The operation rod 20 is provided to be displaceable in the longitudinal direction with respect to the base portion 19a so that the amount of protrusion from the end surface of the base portion 19a can be changed.

  The elastic body 21 is formed of a predetermined member that is linear when no external force is applied, and is easily deformed (bent) when the external force is applied. Even if an external force is applied to the elastic body 21 in the axial direction, the elastic body 21 is not easily deformed. One end portion of the elastic body 21 is provided at one end portion of the operation rod 20 in the internal space of the tube body 19 (the hollow portion of the base portion 19a). The elastic body 21 is disposed such that the intermediate portion passes through the hollow portion of the base portion 19a, the hollow portion of the curved portion 19c, and the hollow portion of the distal end portion 19b. The other end portion of the elastic body 21 is disposed so as to protrude from the other end face of the tube body 19 (end face of the tip end portion 19b).

  As described above, one end of the elastic body 21 is connected to one end of the operation rod 20. For this reason, when the operating rod 20 is displaced with respect to the tube body 19, the elastic body 21 is also displaced with respect to the tube body 19. That is, when the operating rod 20 is displaced in the longitudinal direction with respect to the base portion 19 a, the protruding amount (projecting length) of the elastic body 21 from the distal end portion 19 b changes according to the displacement of the operating rod 20.

  When the elastic body 21 is displaced with respect to the tubular body 19, the elastic body 21 is configured by a tension spring 21a, for example, so that the elastic body 21 can smoothly move through the hollow portion of the curved portion 19c. Is done. The tension spring 21a has a predetermined diameter and length. One end of the tension spring 21a is provided at one end of the operating rod 20 in the hollow portion of the base 19a. The middle part of the tension spring 21a passes through the curved part 19c, and the other end projects from the end surface of the tip part 19b.

  A stopper 21b is provided at the other end of the tension spring 21a. The stopper 21b is provided to prevent the operating rod 20 and the elastic body 21 from being detached from (removed from) the tube body 19. The stopper 21b has a diameter larger than the diameter of the tension spring 21a. The stopper 21b is constituted by, for example, a bolt head. In this case, the screw portion of the bolt is inserted into the hollow portion from the end surface of the other end portion of the tension spring 21a, and the screw portion is bonded and fixed to the other end portion of the tension spring 21a.

The tube body 19 is provided with a measurement scale 19d on the outer surface of the base portion 19a along the length thereof. The scale 19d is disposed on the outer surface of the base portion 19a at least on the surface facing the direction opposite to the direction in which the elastic body 21 protrudes from the end surface of the tip portion 19b.
The operation bar 20 has a measurement scale 20a on its outer surface along its length. The scale 20a is disposed on the outer surface of the operating rod 20 at least on the surface facing the direction opposite to the direction in which the elastic body 21 protrudes from the end surface of the tip 19b.

  The backing plate 22 is for maintaining the posture of the tube body 19 at the time of measurement. The contact plate 22 is made of a plate-like member. The backing plate 22 is provided on the base portion 19 a of the tube body 19. The contact plate 22 is disposed such that the flat side surface 22a faces in a direction opposite to the direction in which the elastic body 21 protrudes from the end surface of the tip end portion 19b.

  The first attachment portion 23 and the second attachment portion 24 will be described later.

  Next, with reference to FIGS. 9 and 10 as well, a method of using the cost measuring apparatus having the above configuration will be described. 9 and 10 are diagrams for explaining a method of using the escalator cost measuring apparatus in Embodiment 1 of the present invention.

  When measuring the cost of the angle member 2 using the above-described cost measurement device, the escalator maintenance person removes the floor board (not shown) forming the upper entrance and exit from the truss 1 and enters the upper machine room 8. To do. In the upper machine room 8, the maintenance person reaches out from the gap between the members constituting the truss 1 so that the side surface 22a of the backing plate 22 is in close contact with the inner side surface 2a of the angle member 2 facing the H steel 3a side. A barbed measuring device is installed.

  Next, the maintenance staff moves the operating rod 20 upward (G direction in FIG. 9) while maintaining the state in which the side surface 22a is in close contact with the inner side surface 2a and the tube body 19 is fixed to the angle member 2. By moving the operating rod 20 upward, the elastic body 21 protrudes in the horizontal direction from the tip 19b, and the other end of the elastic body 21 moves in a direction away from the tip 19b (H direction in FIG. 9).

  The fact that the other end portion of the elastic body 21 is in contact with the end surface of the bearing plate 15a can be recognized by a feeling when the operating rod 20 is being operated. When the other end of the elastic body 21 comes into contact with the end surface of the bearing plate 15a, the maintenance staff reads the scale 20a of the operation rod 20 at that time. This read value is the distance between the inner surface 2a of the angle member 2 and the end surface of the bearing plate 15a.

  Next, the maintenance staff moves the tube body 19 slightly upward, and then measures the distance between the inner surface 2a of the angle member 2 and the end surface of the liner 16a by the same procedure as described above. From the distance between the inner surface 2a of the angle member 2 and the end surface of the bearing plate 15a and the distance between the inner surface 2a of the angle member 2 and the end surface of the liner 16a, the installation state of the angle member 2 is grasped. The allowance can be calculated.

  FIG. 10 shows another method of using the cost measurement apparatus. The maintenance staff of the escalator can also measure the distance between the lower surface 2b of the angle member 2 and the upper surface of the bearing plate 15a by using the above-described bar allowance measuring device. In such a case, the maintenance person reaches out from the gap between the members constituting the truss 1 in the upper machine room 8, the side surface 22 a of the contact plate 22 is in close contact with the inner side surface 2 a of the angle member 2, and the tube body 19 The bar allowance measuring device is arranged in the vertical direction so that the upper end (of the tip 19b) contacts the lower surface 2b of the angle member 2.

  The diameter (thickness) of the tip 19b is known. A scale 19d is attached to the base 19a of the tube body 19 according to the diameter of the tip 19b. For example, when the upper end of the distal end portion 19b is brought into contact with the lower surface 2b of the angle member 2 with the base portion 19a of the tube body 19 arranged in the vertical direction, the angle 19d is positioned at the position of the scale 19d indicating the numerical value of the diameter of the distal end portion 19b. The lower end of the material 2 is arranged. For example, when the diameter of the distal end portion 19b is 10 mm, when the upper end of the distal end portion 19b is brought into contact with the lower surface 2b of the angle member 2 in a state where the base portion 19a of the tube body 19 is disposed in the vertical direction, 10 mm of the scale 19d is indicated. The lower end of the angle member 2 is disposed at the position.

  When the maintenance staff brings the contact plate 22 into close contact with the inner surface 2a and the upper end of the tip 19b is brought into contact with the lower surface 2b, the scale 19d is visually observed, and the lower end of the angle member 2 is arranged at a position of 10 mm of the scale 19d. Make sure. Next, the maintenance person holds the tube body 19 and moves the margin measuring device downward, and places the tip 19b of the tube body 19 on the upper surface of the bearing plate 15a. The maintenance staff places the base portion 19a of the tube body 19 in the vertical direction with the tip portion 19b of the tube body 19 placed on the upper surface of the bearing plate 15a, and in this state, the position of the lower end of the angle member 2 with respect to the scale 19d Read. This read value is the distance between the lower surface 2b of the angle member 2 and the upper surface of the bearing plate 15a.

Embodiment 2. FIG.
As described in the first embodiment, in the escalator already installed in the building, the maintenance staff must measure the cost of the angle member 2 from the upper machine room 8. Since the motor 13 and the control panel 14 are installed in the upper machine room 8, a sufficient work space cannot be ensured. In addition, the maintenance staff cannot directly observe the measurement point when measuring the cost of the angle member 2 from the upper machine room 8.

  FIG. 11 is a diagram showing a fiberscope. In the present embodiment, a case will be described in which the cost of the angle member 2 is measured using the cost measurement device and the fiber scope 25.

  The fiber scope 25 includes a main body 25a, an operation unit 25b, a display unit 25c, a fiber unit 25d, and a lens unit 25e. The lens part 25e is provided at the tip of the fiber part 25d. The distal end portion of the fiber portion 25d is configured to bend in a predetermined direction.

  The first attachment portion 23 and the second attachment portion 24 of the bar allowance measuring device are for attaching the distal end portion (of the fiber portion 25 d) of the fiber scope 25 to the tube body 19. The 1st attaching part 23 and the 2nd attaching part 24 consist of a member which exhibits a short cylindrical shape. The 1st attachment part 23 is provided in the intermediate part (or contact plate 22) of the base 19a, for example. The first attachment portion 23 is disposed in parallel with the base portion 19a. The second attachment portion 24 is provided, for example, at the distal end portion 19b. The 2nd attachment part 24 is arrange | positioned in parallel with the front-end | tip part 19b.

  FIG. 12 is a view for explaining a method of using the escalator cost measuring apparatus in Embodiment 2 of the present invention. FIG. 12 shows a state in which the fiber portion 25d of the fiberscope 25 is attached to the first attachment portion 23 and the second attachment portion 24 of the bar allowance measuring device. The fiber scope 25 is arranged such that the lens portion 25e faces the direction in which the elastic body 21 protrudes from the end surface of the tip portion 19b.

  By attaching the fiberscope 25 to the margin measuring device, the maintenance staff performs various measurement operations while confirming the position of the other end portion of the elastic body 21 and the position of the distal end portion 19b of the tubular body 19 on the display portion 25c. be able to. For this reason, even in the narrow and dark upper machine room 8, the measurement work can be performed accurately and quickly.

In addition, when the diameter of the 2nd attachment part 24 is larger than the diameter of the front-end | tip part 19b of the pipe body 19, according to the diameter of the 2nd attachment part 24, the scale 19d is attached | subjected. In this case, when the maintenance staff brings the contact plate 22 into close contact with the inner side surface 2a and the upper end of the tip end portion 19b is brought into contact with the lower surface 2b, the lower end of the angle member 2 is visually inspected by the scale 19d. Confirm that it matches the position showing the numerical value of the diameter.
Others are the same as in the first embodiment.
