The insertion tool has an iron rod-shaped lever 1 and an iron rod-shaped locking member 2.
The lever 1 has an action portion 4 having a flat stepped portion 3 protruding in the longitudinal direction engaging with the upper end side surface of the skirt guard at a tip portion 1a of the rod, and an intermediate portion 1b extending from the tip portion 1a of the rod in the longitudinal direction. , A fulcrum 6 having a slit 5 orthogonal to the step 3 and a power point 7 formed on a wedge and applied to the other end 1c for applying an external force. The stepped portion 3 is engaged with the upper end surface of the skirt guard to prevent the skirt guard from being displaced in the direction of the balustrade or the step and coming off the lever.
The locking member 2 is formed by bending one end 2a of a rod into a U-shape, and is disposed on a portion sandwiched between balustrades such as a back surface of a step, a trailing rail or a step shaft. .), And a hook 8 for stopping the upward movement of the locking member 2, and the intermediate portion 2 b of the rod engages with the slit 5 of the lever 1 to support the fulcrum 6 of the lever 1. And a mark portion 10 wound on the other end 2c of the rod at the other end 2c so as to indicate the bending direction of the locking portion 8 on the same plane as the bending by a half turn. The locking portion 8 has a bent portion 8a bent when viewed from the end 2a of the locking member 2, and a straight portion 8b connected to the bent portion 8a. The projections 11 such as three nuts are fixed to the support portion 9 by welding or the like at a distance. The locking portion 8 is covered with a protective film 12 made of a dip-coated film of polyethylene or the like.
[0009]
The skirt support 13 has an upper support 14 and a lower support 15 as shown in FIG. The upper receiving member 14 extends in the moving direction of the escalator, is fixed to the lower trust 16, has a cross-sectional shape obtained by rotating the L-shape by 180 degrees, and has an upper surface portion 14a and a side portion 14b facing the step 17. are doing. The side surface portion 14b has screw holes 20 aligned with the holes 19 of the upper end portion 18a of the skirt guard 18 at equal intervals in the moving direction of the escalator. An opaque panel 21 is fixed to the upper surface 14a with screws 22. On the other hand, like the upper receiving member 14, the lower receiving member 15 extends in the moving direction of the escalator, and is fixed to the lower trust 16, has a reverse L-shaped cross section, and faces the lower surface portion 15a and the step 17. And a rising portion 15b.
[0010]
The skirt guard 18 is fixed to the lower edge portion 18b along the moving direction of the escalator with an opening downward, and is attached to a leaf spring 23 fitted to the rising portion 15b of the lower receiving member 15, and to the upper edge portion 18a. And a hole 19 corresponding to the screw hole 20.
[0011]
Next, a procedure for inserting and fixing the skirt guard 18 to the skirt receiving member 13 using this insertion tool will be described.
The skirt guard 18 is first dropped into the gap between the step 17 and the side surface 14b of the upper receiving member 14 and the rising portion 15b of the lower receiving member 15 while abutting the side surface thereof. The lowering of the skirt guard 17 stops when the leaf spring 23 hits the rising portion 15b of the lower receiving member 15. At this time, the leaf spring 23 and the rising portion 15b are lightly fitted, and if a force is applied downward from the upper end surface 18c of the skirt guard 18, the leaf spring 23 can be fitted more strongly. Next, the locking portion 8 of the locking member 2 of the insertion tool is inserted into the gap between the skirt guard 18 and the step 17 so that the surface including the bending of the locking portion 8 is parallel to the skirt guard 16. . Since the gap is about 10 mm at the maximum, it cannot be inserted perpendicularly to the skirt guard 16. Also, if the bending of the locking portion 8 is reduced, the locking portion 8 cannot be securely locked to the step back surface 15a. Next, the locking member 2 is rotated by 90 degrees in the horizontal direction with the mark portion 10 as a mark so that the bending of the locking portion 8 is perpendicular to the skirt guard 16, and then the bent portion 8a of the locking portion 8 is formed. Raise it until it hits the step back surface 15a. Next, the support 9 is pushed into the slit 5 from the skirt guard 18 side toward the step 17 side, with the upper surface of the lever 1 being arranged to contact the lower surface of the nut 26 of the locking member 2. Next, the step 3 of the lever 1 is engaged with the upper end surface 18c of the skirt guard 18.
[0012]
In this way, the upward movement of the locking portion 8 of the locking member 2 of the insertion tool is restricted by the step back surface 17a. The lever 1 constitutes a lever with the fulcrum supported by the nut 26 of the locking member 2, the operating part 4 engaged with the skirt guard 18 and the power point 7 as the power point. When the force point portion 7 is pushed upward, the skirt guard 18 is pushed down, and the rising portion 15 b of the lower receiving member 15 is strongly pushed into the gap of the leaf spring 23. At this time, the skirt guard 18 is pushed down while aligning the hole 19 of the skirt guard 18 with the screw hole 20 of the upper receiving bracket 14. Since the skirt guard 18 has a width of 1 m or more in the moving direction of the escalator, the insertion work described above is performed at several places to align the positions of the holes 19 and the screw holes 20, and the skirt guard 18 is fixed with the screws 22 so as to be fixed. The operation of inserting and fixing the 18 into the skirt fitting 12 is completed.
[0013]
Next, a procedure for using the plurality of nuts 26 will be described. At the start of the insertion operation, the position of the upper end surface 18c of the skirt guard is almost the same height as the uppermost nut 26, so that the upper surface of the lever-1 is attached to the lower surface of the uppermost nut 26. The support 9 is pushed into the slit 5 from the skirt guard 18 side toward the step 17 side. However, when the skirt guard 18 is pushed down, the position of the upper end face 18c of the skirt guard 18 becomes considerably lower than the uppermost nut 26, and the locking member 2 and the lever 1 become almost parallel. Then, the lever 1 is pulled out from the slit 5, and the lever 1 is arranged so that the upper surface of the lever 1 is in contact with the lower surface of the nut 26 located in the middle, and the support portion 9 is slit from the skirt guard 18 side to the step 17 side. Push into 5. Further, when the skirt guard 18 is pushed down, the lever 1 is supported by the nut 26 located further below. When the nuts having different heights are sequentially used as the support portions of the lever 1, the locking member 2 and the lever 1 become close to vertical, and it is easy to push up.
[0014]
If the skirt guard 18 is depressed too much, the gripping portion 7 of the lever 1 is brought into contact with the lower end surface 18d of the skirt guard 18 from the gap between the skirt guard 18 and the step 17, and is supported at the corner of the step 17. As a supporting point, the skirt guard 18 can be slightly lifted.
[0015]
When the old skirt guard 18 is removed and the new skirt guard 18 is replaced, the grasping portion 7 of the lever 1 is applied to the lower end face 18d of the skirt guard 18 from the gap between the skirt guard 18 and the step 17, and the angle of the step 17 is changed. And the skirt guard 18 can be lifted and removed.
[0016]
Such an escalator skirt guard insertion tool can insert the skirt guard with a small force by using a lever supported by a locking member that can be hooked and fixed to the main body of the escalator such as the back of the step, the following rail or the step shaft, Fine adjustments can be made while watching the displacement of the holes little by little.
[0017]
Further, since the locking portion is covered with a protective film such as a dip coating film, the surface of the skirt guard is not damaged.
[0018]
Also, since the mark part is wound in the same plane as the locking part, it is possible to make an approximate registration of the part that is in contact with the escalator body such as the step back surface of the locking part, the following rail or the step shaft. it can. Further, since the length of the locking portion is larger than the gap between the skirt guard and the step, the locking portion does not come off from the back surface of the step, the following rail, or the step shaft during the insertion operation.
