Abstract

PURPOSE:To provide an escalator cleaning tool which can gather the dust to the manhole side by setting the length of the operation part so that the grip projects upward from the floor surface of the escalator gateway when a brush is contacted with the floor surface of a lower machine room, and setting the length of a brush mounting part some smaller than the dimension between the front wheel rails for the steps. CONSTITUTION:A cleaning tool for escalator is composed of an operation part 1 and a brush mounting part 2, wherein the operation part 1 is fitted with a grip 3 while the part 2 moves similarly in linkage with the left-right motion of the grip 3. The level of the operation part 1 is set so that the grip 3 projects upward from the floor surface of the escalator gateway to provide an easy-to- grasp positioning when a brush 4 is grounded on the floor surface of a lower machine room, and the length of the brush mounting part 2 is made some smaller than the dimension between the front wheel rails in order to facilitate the coming-in and going-out to/from the machine room. This cleaning tool is inserted between the step and lower machine room floor and rotated to the left and right, and thereby the dust is gathered to the manhole side, which leads to enhancement of the efficiency of the cleaning works.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator cleaning tool suitable for cleaning the floor surface of a lower machine room of an escalator.

[0002]

2. Description of the Related Art Conventionally, when cleaning a floor surface of a lower machine room of an escalator, for example, as shown in Japanese Utility Model Laid-Open No. 2-86453, a large number of small suction holes connected to a suction port of an electric vacuum cleaner are provided. Insert the flat pipe provided in the gap between the floor of the lower machine room (oil pan) of the escalator and the steps on the floor so that dust on the floor can be sucked in through the small holes in the flat pipe, It was designed to collect dust in the dust collection chamber inside the cleaner body.

[0003]

In the above-mentioned cleaning with the flat pipe, dust on the floor surface causes the suction small hole of the flat pipe to be immediately clogged, so the work for removing the clog is repeated many times. It was necessary and inconvenient. Further, the gap between the floor of the lower machine room and the steps on the floor is about 30 mm, which is narrow. Therefore, it is difficult to insert and move the flat pipe into the gap, and the cleaning workability is extremely poor.

In view of the above problems, an object of the present invention is to provide an escalator capable of collecting dust between the floor surface of the lower machine room and the steps on the floor to the manhole side of the lower machine room. To provide cleaning tools.

[0005]

The above-mentioned object comprises a brush mounting portion on which a brush is mounted, an operating portion extending upward from one end of the brush mounting portion, and a handle portion mounted on the upper end of the operating portion. The length of the operating portion is set so that the grip portion projects upward from the floor surface of the escalator entrance / exit when the brush is in contact with the floor surface of the lower machine room of the escalator, and the brush is mounted. This can be achieved by setting the length of the portion to be smaller than the dimension between the front wheel rails of the step rails on the escalator.

[0006]

[Function] When cleaning the floor surface of the lower machine room, the escalator cleaning tool is inserted into the manhole of the lower machine room, and the brush mounting part of the escalator cleaning tool is inserted between the step and the lower machine room. After inserting it into the gap, the operating part of the cleaning tool for the escalator, which is protruding from the manhole above the floor of the entrance / exit, is gripped, and the brush mounting part is rotated. When the brush mounting portion is rotated, the dust in the gap between the step and the lower machine room is scraped by the brush to a portion above the floor of the lower machine room where there is no machine such as the step.
The collected dust may be sucked at the suction port of the vacuum cleaner. In this case, the suction port is operated in a wide space that is not disturbed by machinery such as steps without being inserted in the gap between the steps and the lower machine room, so that dust collection work by the electric vacuum cleaner can be performed smoothly. Done. Also, since the operating portion of the escalator cleaning tool projects above the floor of the entrance / exit entrance, the operator can rotate the brush while sitting down on the floor surface of the entrance / exit entrance, and the operator can operate the cleaning tool for the escalator. It has excellent properties. Further, since the length of the brush mounting portion is smaller than the length between the front wheel rails in the step rail, it is possible to rotate the brush mounting portion without being disturbed by the front wheel rail.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. The escalator cleaning tool of this embodiment is for cleaning the floor surface of the lower escalator machine room. This escalator cleaning tool comprises an operating section 1 and a brush mounting section 2, which are integrally configured. A grip portion 3 is provided on the operation portion 1, and the brush mounting portion 2 also moves in the same manner as the grip portion 3 moves left and right. Then, the brush 4 is bonded to the brush mounting portion by a bonding means 5 with a double-sided adhesive tape or the like.

The operating part 1 has a height of 1320 mm and the brush mounting part has a length of 1110 mm. Both are made of aluminum steel, and the handle part 3 has a length of 160 mm and 50 mm.
With φ, the same material as the length of the brush 4 of 1100 mm is used and urethane foam is used.

FIG. 2 is a cross section of the brush mounting portion 2, the brush 4, and the bonding means 5. A thickness of 15 mm can be inserted into a gap of 30 mm between the steps 6 and the lower machine room floor 7, and a width of 25 mm is It takes into account the contact resistance with the floor of the machine room when moving left and right. The height of the operating portion is set so that when the brush 4 is grounded on the floor surface of the lower machine room, the grip portion 3 projects above the escalator entrance / exit floor surface 8 and is in a position where it can be easily gripped. The length is set to be smaller than the dimension between the front wheel rails in order to prepare for entry into and exit from the machine room.

FIG. 3 shows an example in which an escalator cleaning tool is put between the steps 6 and the lower machine room floor 7 to carry out the operation. By rotating the escalator cleaning tool to the right from the position on the lower machine room left side 8 and then to the left from the position on the lower machine room right side 9, the dust on the lower machine room floor 7 is removed from the manhole side 10.
It has a structure that can be scraped and easily cleaned.

FIG. 4 shows another embodiment of the present invention, in which the brush mounting portion 2a is made elastic so that the cleaning range can be adjusted, and the connection with the operating portion 1a is made by a pin connection 1b. By adopting this, the structure is made to fold when moving.

[0012]

According to the present invention, it is possible to provide a cleaning tool for an escalator, which can easily remove dust accumulated between machinery such as steps and the floor surface of the lower machine room to improve the efficiency of cleaning work.
