The front end of the seal lip 80 protrudes forward from the front end opening of the case 41. As a result, when the case 41 descends along the truss slope 12a as shown in FIG. 9 described later, the seal lip 80 makes it easier for the oil on the truss slope 12a to be taken into the inside of the case 41. The seal lip 80 may be omitted, and the oil may be taken in directly from the front end of the bottom plate portion 43 of the case 41 to the inside of the case 41.

Further, as shown in FIGS. 5 and 6, in the middle portion in the front-rear direction of the bottom plate portion 43 of the case 41, in the portion near both ends in the left-right direction, a protrusion 81 having a triangular cross section or the like protruding upward so as to extend in the left-right direction Is formed. For example, the protrusion 81 may be formed by a rib formed by crimping a part of the bottom plate portion 43 upward.

As shown by arrows P1, P2, and P3 in FIG. 6, the cleaning jig 40 sends oil from the front end opening 42 to the rear side inside the case 41 and folded back at the rear end portion of the case 41. The case 41 is configured to be recoverable by two pocket portions 53 formed at both ends in the left-right direction.

Next, a truss slope cleaning oil disposal method performed using the cleaning jig 40 will be described. The truss slope cleaning oil disposal method includes a jig support step, an escalator operation step, a jig removal step, a lid removal step, and an oil disposal step.

FIG. 9 is a cross-sectional view showing a method of cleaning the truss slope 12a using the cleaning jig 40 in the embodiment. In the jig support step, the cleaning jig 40 is supported on the step shaft 31 in a state where the step shaft 31 of the step on the return path side of the escalator is inserted through the shaft support portion 72. At this time, the step shaft 31 is removed from the existing step 30 (FIG. 2), the cleaning jig 40 is supported so that the step shaft 31 is inserted into the shaft support portion 72, and then the step shaft 31 is assembled to the step 30. You may do so.

In the escalator operation step, the escalator is operated in the ascending direction so that the cleaning jig 40 descends along the truss slope 12a. As a result, as shown in FIG. 9, the cleaning jig 40 moves in the direction of the arrow γ.

At this time, the case 41 is elastically pressed against the truss slope 12a by the spring 71 in the direction of the arrow δ. As a result, even if the distance between the truss slope 12a and the shaft support portion 72 changes, the case 41 can easily follow the truss slope 12a within the range in which the spring 71 can expand and contract. At this time, the lid portion 60 functions as a weight for facilitating pressing the cleaning jig 40 against the truss slope 12a. Then, since the case 41 descends in a state where the lower end of the seal lip 80 is in contact with the truss slope 12a, the oil on the truss slope 12a is rearward from the front end opening 42 inside the case 41 as shown by the arrow η. Will be sent to. Then, the oil is folded back to the front side at the rear end portion of the case 41 while flowing to both sides in the left-right direction at the peripheral wall portions 63a and 63b on the front side of the lid portion 60 as shown in FIGS. The cleaning jig 40 allows the oil folded back in this way to get over the protrusions 81, and the two pocket portions 53 formed between the left and right side surfaces of the case 41 and the two inlet walls 50a and 50b. Collect at. The oil that has entered the pocket portion 53 is prevented from leaking to the outside of the case 41 when lowered by the peripheral wall portions 63a and 63b on the upper side of the pocket portion 53. Further, the protrusion 81 formed on the bottom plate portion 43 of the case 41 can more effectively suppress the leakage of oil from the pocket portion 53.

Then, when the truss slope 12a is moved from the upper side to the lower side at a predetermined position, the operation of the escalator is stopped and the cleaning work is completed.

In the jig removal step, the cleaning jig 40 is removed from the step shaft 31 after the operation of the escalator is stopped. In the lid removal step, the operator grasps the handle 64 and holds the cleaning jig 40 in a state where the front end opening 42 faces downward and the oil in the pocket portion 53 does not leak. Remove the lid 60 from the. As a result, the front side of the rear end opening 48a of the case 41 communicates with the inner space of the case 41 from which the oil has been collected.

In the oil disposal step, after removing the lid 60 from the cleaning jig 40, the operator changes the direction of the case 41 so that the rear end opening 48a is facing down, and the inside of the cleaning jig 40 is passed through the rear end opening 48a. Discard the oil. At this time, if solid foreign matter such as dust is collected together with the oil in the case 41, the foreign matter is also discarded together with the oil.

According to the cleaning jig 40 and the truss slope cleaning oil disposal method configured as described above, the truss slope can be lifted by simply operating the escalator in the ascending direction with the cleaning jig 40 supported by the step shaft 31 of the escalator. Can clean the oil. As a result, cleaning of the truss slope 12a can be simplified. Further, after the cleaning work is completed, the oil in the pocket portion 53 can be disposed of simply by removing the cleaning jig 40 from the step shaft 31 and removing the lid portion 60, so that the operator's oil disposal work can be facilitated.

In the above description, the case where the shaft support structure 70 is connected to both ends in the left-right direction of the upper end portion of the case 41 has been described, but there is only one shaft support structure at the center portion in the left-right direction of the upper end portion of the case 41. It may be combined. On the other hand, from the viewpoint of stably supporting the case 41 on the step shaft 31, it is preferable to connect the two shaft support structures 70 on both the left and right sides of the case 41 as described above.

FIG. 10 is a diagram showing a shaft support portion 72a in another cleaning jig of the embodiment. As shown in FIG. 10, the shaft support portion 72a in the cleaning jig of another example has a lower semicircular portion 82 coupled to the upper end of the bolt 73 and one end portion of the lower semicircular portion 82 (the left end portion in FIG. 10). ) Includes an upper semicircular portion 83, one end of which is swingably coupled. The other end of the upper semicircular portion 83 (the right end in FIG. 10) is detachably coupled to the other end of the lower semicircular portion 82 by an uneven engaging portion or the like. When such a shaft support portion 72a is used, the shaft support portion 72a can be easily installed in the intermediate portion of the step shaft 31 with the step shaft 31 (FIGS. 2 and 9) mounted on the step 30 (FIG. 2).
