Description

[Detailed Description of the Invention] This invention relates to an improvement of a building cleaning machine that includes a roof car and an elevating body suspended from the roof car and cleans the exterior of a building.

First, a conventional building cleaning machine will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is a building, 1a is the roof of this building, 1b is a row of windows of building 1, 1c is a window row arranged closer to the front with a distance of the dimensions shown in FIG. are guide rails provided along each of the window rows 1b and lc,
2 is a window glass, 3 is a rail provided along the edge of the rooftop 1a, 4 is a roof car that moves on the rail 3, 5 is a hoisting machine provided on this and has a rope 6 wound around it, 7
8 is a pulley that guides the rope 6, 8 is an arm that supports and moves the pulley 7, 8a is a guide roller provided on the roof car 4 and holds the arm 8, 9 is a hydraulic cylinder or an electric cylinder, etc., and one side is attached to the roof car 4. a driving device for the arm 8 fixed and attached to the arm 8 on the other side, 10;
is a holding rail provided on the arm 8, 10a is attached to the holding rail 10, and the guide rail (1d) and the holding rail 1o are attached to the holding rail 10.
A limit switch 11 is an elevating body consisting of an automatic cleaning machine suspended from a rope 6 and engaged with a holding rail 10.

That is, when cleaning, first the arm 8 is moved by the drive device 9, the holding rail 10 is aligned with the perpendicular line of the guide rail 1d on the building side via the limit switch 10a, and then the hoisting machine 5 is driven to automatically The cleaning device 11 is lowered, and the window rows 1b and lc are cleaned by the operation of the automatic cleaning device 11.

In this way, the position of the guide rail 1d on the building 1 side is the window row 1b.
, lc, cleaning is performed by moving the arm 8 to align the holding rail 10 with the guide rail 1d.

However, on the other hand, the arm 8, the guide roller 8a, the drive device 9
is required, resulting in a complicated structure, and when the amount of movement of the arm 8 is small (for example, about 10 orrr IIL), the device becomes large-scale and expensive.

This invention solves the above-mentioned drawbacks and aims to provide a building cleaning machine that is simply constructed and can handle even when the position of the guide rail on the building side is slightly moved in and out due to the row of windows.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6.

In the figure, the same reference numerals as those in FIGS. 1 to 3 indicate corresponding parts, and 12 is an actuating device consisting of a hydraulic cylinder or an electric cylinder, etc., and one side is fixed to the roof car 4 and the other side is a holding rail 10.
They are mounted on the upper and lower ends of the holding rail 10, respectively, and by operating them in synchronization, the holding rail 10 is moved back and forth in a vertical state.

In other words, in a window row arranged at a distance from the window row 1b as shown in FIG. 6, such as the window row 1C, it is necessary to operate the actuating device 12 by the distance to align the holding rail 10 with the perpendicular line of the guide rail 1d. However, during this operation, the pulley 7 that guides the wire rope 6 does not move.

Therefore, only the holding rail 10 and the elevating body 11 engaged therewith move to a predetermined position, and the wire rope 6 suspending it is inclined at an angle θ shown in FIG. 5 with respect to the perpendicular line.

However, if the amount of movement of the holding rail 10 is appropriately restricted (
For example, if it is up to about 700TUn), there is no effect of this slope.

In this way, the holding rail 10 can be operated as required by a simple mechanism using only the actuating device 12, and manufacturing costs can be reduced.

As explained above, this invention has a holding rail that holds the elevating body, one side of which is fixed to the roof car and the other side attached to the holding rail, and this holding rail can be moved forward and backward independently of other equipment installed on the roof car. Since the robot can be moved to a predetermined position by itself using an actuating device, an inexpensive building cleaning machine that can handle a cleaning surface consisting of a row of windows with entrances and exits can be realized with a simple mechanism.

Claims (1)

[Scope of utility model registration request] In a building cleaning machine that is used in a building where the window rows on the exterior wall surface to be cleaned partially protrude or recede, and has a roof car that runs on the roof of the building, the roof car has a roof car installed on the roof car. an elevating body that is suspended by a hoist and engages with a guide rail provided on the building to move up and down; a holding rail that is provided on the roof car and engages with the elevating body and holds it so that it can be raised and lowered; One side is fixed to the roof car, and the other side is attached to the holding rail, and the holding rail is moved forward and backward independently of other equipment provided on the roof car, thereby causing the protruding or retracting. A building cleaning machine is provided with an actuation device that matches the guide rail of the window row.
