Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an oil pan cleaning device for an escalator, which cleans an oil pan by a brush sliding on the surface of the oil pan as a step moves.

[0002]

[Prior Art]

 Conventionally, for example, as described in Japanese Utility Model Application Laid-Open No. 50-91992, a frame body detachably attached to a tread surface of a step moving in a horizontal plane or a plane close to horizontal, and an oil provided on the frame body. An oil pan cleaning device for passenger conveyors has been proposed which is composed of a brush capable of rubbing the surface of the pan. In this conventional oil pan cleaning device, the tip of the elastic member of the brush rubs the surface of the oil pan when the step moves on the return path side, so that the foreign matter on the oil pan is removed, that is, The oil pan is cleaned.

[0003]

[Problems to be solved by the device]

 By the way, generally, in an escalator, as shown in FIG. 4, a plurality of steps 1 continuously connected in an endless manner horizontally move in the vicinity of the upper entrance 2 and the lower entrance 3, and these entrances 2, 3 It is designed to skew at the center of the space. For example, when the step 1 moves in the direction of the arrow in FIG. 1, the step 1 is raised in the upper machine compartment 2a after the step 1a is lifted up from the lower entrance 3 to the upper entrance 2 with the tread 1a facing upward. Rotate 4 counterclockwise. Next, with the tread 1a facing downward, the step 1 descends on the return path from the upper machine room 2a to the lower machine room 3a. The oil pan 4 extending downward along the return path of the step 1 has horizontal portions 4a and 4b at both ends and an intermediate portion having an inclination angle of about 30 ° with respect to these horizontal portions 4a and 4b. It is composed of the inclined portion 4c. A space of, for example, about 40 mm to 200 mm is formed between the tread surface 1a of the step 1 on the return path side and the oil pan 4. Further, as the step 1 rotates, foreign matters such as dust and dust attached to the tread 1a fall from the tread 1a and accumulate on the oil pan 4.

In the above-mentioned conventional oil pan cleaning device, the oil pan has a horizontal shape or a shape close to horizontal, and the length of the elastic member of the brush that rubs the surface of the oil pan is special. No consideration is given. When such an oil pan cleaning device is to be installed in the above-described escalator, the distance between the tread surface 1a and the oil pan 4 is about 40 mm to 200 mm as described above, which varies considerably. It is difficult to rub the tip of the elastic member of the brush over a wide range, and in particular, there is a concern that foreign matter on the horizontal portions 4a and 4b cannot be reliably removed.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and an object thereof is to provide an oil pan cleaning device for an escalator capable of rubbing the surface of the oil pan over a wide range. is there.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the present invention provides a frame body that is detachably attached to the tread surface of an endlessly continuous step, and an oil pan provided on the frame body and extending below the step. In the oil pan cleaning device of the escalator, which comprises a brush capable of rubbing the surface of the oil pan, the brush is made of elastic members of various lengths that are predetermined according to the distance between the tread surface and the oil pan. It has a configuration.

[0007]

[Action]

 According to the present invention, as described above, the length of the elastic member of the brush is preset to various dimensions according to the distance between the tread surface of the step and the oil pan. When moving, the tip of a relatively short elastic member rubs against the surface of the oil pan when the distance is small, and the tip of a relatively long elastic member moves when the distance is large. Rub the surface. As a result, the surface of the oil pan can be rubbed over a wide area.

【Example】

 An embodiment of the oil pan cleaning device for an escalator according to the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of an oil pan cleaning device of the present invention mounted on a step of an escalator, FIG. 2 is a front view of the step shown in FIG. 1, and FIG. 3 is an oil pan cleaning device of FIG. FIG. 4 is a side view of the escalator showing a state where the oil pan is cleaned. 1 is a view of the steps of FIG. 2 as seen from the line AA. Further, the same components as those shown in FIG. 4 described above in FIGS. 1 to 3 are designated by the same reference numerals. That is, 1 is a step, 1a is a tread, 2 and 3 are entrances and exits, 2a and 3a are machine rooms, 4 is an oil pan, 4a and 4b are horizontal parts, and 4c is an inclined part.

The step 1 of the escalator shown in FIG. 1 is mounted on the frame body 4, a frame body 4 on which a tread surface 1 a is fixed, a front wheel shaft 5 and a rear wheel shaft 6 rotatably provided on the frame body 4, and a frame body 4. The riser 7 covers the rear wheel shaft 6 side, and as shown in FIG. 2, has a front wheel 5a and a rear wheel 6a mounted on the front wheel shaft 5 and the rear wheel shaft 6, respectively.

The oil pan cleaning device according to the present embodiment is provided with a frame 8 detachably attached to the tread 1a of the step 1, and a brush provided on the frame 8 for rubbing the surface of the oil pan 4. It consists of a rash 9. The brush 9 is composed of elastic members having a large elastic force and which are bristled in the frame body 8, for example, a plurality of piano wires 9a to 9g, and these piano wires 9a to 9g are the tread surface 1a and the oil pan 4. It has various length dimensions that are predetermined depending on the distance between the and. Among these piano wires 9a to 9g, the shortest piano wire 9a is arranged on the front wheel shaft 5 side, the piano wires 9b to 9f are arranged in ascending order from the relatively short one, and the longest piano wire 9g is arranged rearward. It is arranged on the wheel axle 6 side.

A plurality of protrusions 10 that engage with the cleat grooves of the tread surface 1 a of the step 1 are provided on the bottom of the frame body 8 described above. There are provided brackets 11 and 12 that engage with each other, and retaining bodies 13 and 14 that retain the engaged state of these brackets 11 and 12.

In this embodiment, an operator enters the upper machine room 2a and attaches the frame body 4 of the oil pan cleaning device to the tread surface 1a of any step 1. At this time, the projections 10 of the frame body 4 are engaged with the cleat grooves of the tread surface 1a, respectively, and the tips of the brackets 11 and 12 are engaged with the front wheel shaft 5, and the engagement state is retained by the retaining bodies 13 and 14. It is designed to be held by. Next, while contacting another worker in the lower machine room 3a, the step 1 is driven in the direction of the arrow in FIG. 3 so that the step 1 descends the return path from the upper machine room 2a to the lower machine room 3a. In doing so, the brush 9 rubs the surface of the oil pan 4 to remove the foreign matter 15 on the oil pan 4. For example, when the distance between the tread 1a of the step 1 and the oil pan 4 is small, the tip of a relatively short piano wire 4a rubs against the surface of the oil pan 4, and when the distance is large, a relatively long piano wire 9g, etc. The tip portion of the is rubbed against the surface of the oil pan 4.

Next, after the piano wire 9g of the brush 9 is separated from the horizontal portion 4b of the oil pan 4, the operation of the step 1 is stopped, and the worker inside the lower machine room 3a removes the retaining bodies 13, 14 from outside. By doing so, the engaged state of the brackets 11 and 12 is released, and then the frame body 8 is removed from the tread surface 1a. Depending on the dirt condition of the oil pan 4, the above-mentioned cleaning work is repeated.

In the embodiment thus constructed, the brush 9 is composed of the piano wires 9a to 9g having various lengths, so that the surface of the oil pan 4 is rubbed by the brush 9 over a wide range. be able to.

[0015]

[Effect of the device]

 Since the present invention is configured as described above, the surface of the oil pan can be rubbed over a wide range, and therefore foreign matters on the oil pan can be considerably removed, and more effective cleaning can be performed.
