[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION In the present invention, a wall is blasted by a blast device which is configured to be able to move vertically and horizontally on the wall while projecting shots on the wall and collecting the shots. Improvement of wall cleaning equipment.

[0002]

2. Description of the Related Art In general, this type of equipment is designed so that the blast device is moved on the wall surface by remote control while the operator monitors the movement of the blast device and the wall surface with the naked eye, and cleans the blast device. Therefore, if the operator is required to perform mental and physical labor and requires skill in operating the equipment, and it is not possible to sufficiently monitor the movement of the blast device and its wall surface, The blast device rises and descends while meandering greatly, and there is a problem that a portion that is not polished or a portion that is excessively polished is generated on the wall.
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a wall cleaning apparatus capable of appropriately moving a blast device up and down with respect to a wall without monitoring by an operator.

[0003]

In order to achieve the above-mentioned object, the wall surface cleaning equipment according to the present invention is capable of projecting shots on a wall surface and moving the wall vertically and horizontally while collecting the shots. In the wall surface cleaning equipment configured to clean the wall surface by using the blast device configured as described above, the presence of the detected member when approaching the bar-shaped detected member oriented vertically along the wall surface The blasting device is characterized in that two sensors capable of detecting the pressure are mounted on the blasting device with a predetermined interval between them with the detected member interposed therebetween.

[0004]

The wall cleaning equipment thus configured detects the presence of the detected member by one of the two sensors, and operates the shot projecting device in the direction of the sensor that has detected the presence of the detected member. Make them run on their own. This allows
The blast device is automatically prevented from being largely moved in the horizontal direction, and moves up and down along the detected member while reducing the meandering width.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to FIGS. As shown in FIG. 2 which is a front view, at the lower end of the wire rope 2 of the wire rope hoisting device 1,
A blast device 3 configured to be capable of moving vertically and horizontally on the wall surface S while projecting shots on the wall surface S and collecting the projected shots is mounted. further,
On the left side of the wire rope winding device 1, a rope 4 as a detected member is attached with a support member 18 so as to hang down at a required distance from the wire rope winding device 1 and along the wall surface S. . FIG.
As shown in FIG. 1 which is an enlarged detailed view of the main part of FIG. 1, a proximity switch as two sensors capable of detecting the presence of the rope 4 when approaching the rope 4 is provided near the left central part of the blasting device 3. As shown in FIG. 4, the two proximity switches 5 and 6 are arranged at a required distance from each other with the rope 4 interposed therebetween, as shown in FIG. Usually, the presence of the rope 4 cannot be detected, and the rope 4
Can be detected.

As shown in FIG. 1, in the blasting device 3, two rotating shafts 9, 10 are provided on the left and right sides of a traveling platform 8 attached to the lower end of the wire rope 2, respectively. A special wheel 11 is fitted on each of the upper and lower ends of the rotating shafts 9 and 10. In the special wheel 11, as shown in FIGS. 5 and 6, a plurality of rollers 13 are pivotally mounted on a peripheral portion of a disk-shaped wheel main body 12. As shown in FIG. 1, an output shaft of a motor 14 mounted on the traveling platform 8 is connected to a lower end of the rotating shaft 9, and the rotating shafts 9 and 10 are connected to a chain wheel 15 and an endless roller chain. When the special wheel 11 rolls on the wall surface S by driving of the motor 14, the traveling platform 8 self-runs in the left-right direction. The traveling platform 8 is moved up and down through the rotation of the rollers 13 of the special wheels 11 by the winding and unwinding of the wire rope 2 by the forward and reverse driving of the hoisting device 1.

As shown in FIG. 3, which is a cross-sectional view taken along the line AA of FIG. 1, the traveling platform 8 has a projection device main body 15 for projecting a shot obliquely upward toward the wall surface S, and a projected wall surface S
A sealing mechanism 1 for sucking and collecting shots bounced off and supplying a shot to the projection device main body 15 for sealing between the shot collecting mechanism 16 and the wall surface S
7 are provided.

The equipment constructed in this way drives the blasting device 3 with the wire rope 2 up and down along the wall surface S by forward and reverse driving of the hoisting device 1 while driving the projecting device body 15 and the shot collecting mechanism 16 and the like. The wall S is cleaned. In this case, when the blast device 3 moves up and down with a bias with respect to the rope 2, for example, when the proximity switch 5 on the left side detects the presence of the rope 2, the blast device 3
Has moved too far to the right. As a result, the motor 14 of the blast device 3 is driven, the special wheels 11 are rotated, and the traveling platform 8 is moved to the left. In this way, when the motor 14 is driven forward and backward as appropriate during the up and down movement of the blast device 3 and the special wheel 11 is rotated forward and backward, the blast device 3 is automatically corrected in the left-right direction and the meandering width is reduced. While going up and down along the rope 2.

Although the rope 2 is used as a member to be detected, any member may be used as long as it has a bar shape and extends vertically. Further, although the proximity switches 5 and 6 are used as sensors, other conventional position sensors, for example, limit switches may be used. Further, the blast device 3 may use a device configured to move up and down by itself without using the wire rope hoisting device 1.

[0010]

As is apparent from the above description, according to the present invention, two sensors capable of detecting the presence of a detected member when approaching a required distance to a detected member hanging down along a wall surface are used. Since the blast device is mounted on the blasting device with the required distance between the blasting device and the blasting device, the blasting device is automatically prevented from moving large in the horizontal direction, and the blasting device is reduced while the meandering width is reduced. As a result, as with conventional equipment of this type, the operator does not constantly monitor the movement of the blasting device, but rather lifts or lowers the surface mechanically, and cleans or grinds the wall. It has excellent practical effects, such as being able to accurately polish without oversweeping.
