Abstract

PURPOSE:To improve adsorption movement, variation of a direction, and durability of a device, especially durability to excitation by a method wherein a movement direction varying mechanism for a device to process a wall surface as it is moved in a state to be adsorbed on a wall surface is brought into surface contact with a body part for support. CONSTITUTION:A rubber hose 3 is communicated with a vacuum suction device, a space formed with a cylinder body 1 with a cover, an adsorption seal 2, and a wall surface is brought into a negative pressure state, and a whole device is adsorbed on the wall surface W. With an exciting device 11 actuated, the whole of the device is vibrated leftwardly obliquely upwardly to repeat rocking based on the wall surface W, and the device is moved leftward. During this movement, a wall surface processing device mounted to the cylinder body 1 with a cover is actuated to continue processing of wall surface. When the moving direction of the device is varied, a chain wheel 14 is rolled in an engaged state along a chain 6 with the aid of a geared motor 12. This constitution causes slide movement of revolving guide bodies 8, 8, 8, and 8 in an integrally formed state as they are brought into surface contact with an annular recessed groove 5, and causes movement of the exciting device 11 along with the slide movement of the revolving guide plates and the stop of the device in a proper position.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus that vacuum-adsorbs the wall surface of a building or a gas tank, such as a vertical surface or a ceiling surface, and processes the wall surface while moving.

(Prior art and problems) Conventionally, the above-mentioned device has been developed that uses excitation force to move the device, but the device that changes the direction of movement is rotatable using rollers etc. in the device body. This support mechanism using rollers and the like has a problem that it is not durable against vibrations by a vibration device and is damaged in a short period of time because it is supported by point contact or line contact.

The present invention has been made with the aim of solving the above problems.

(Means for Solving the Problems) The present invention includes attaching an adsorption seal to the periphery of the opening of a cylindrical body with a lid having a cross-sectional opening shape, and connecting the cylindrical body with a lid to a suction pipe that communicates with a vacuum suction device. In the wall suction moving device, a guide member having an annular groove facing outward is provided on the outer circumferential side of the cylindrical body with a lid, and a chain is attached parallel to the guide member at an appropriate distance, and a chain is attached in parallel to the annular groove. Four swing guide plates are slidably fitted into the grooves at equal intervals, and each swing guide plate is connected by four arc-shaped rings. A rotating guide plate is provided with mounting seats, a vibration excitation device is mounted on one mounting seat 1, a gear motor is provided on the other mounting seat, and a chain wheel that meshes with the chain is mounted on the rotating shaft of the gear motor. That is.

(Example) Examples of the present invention will be described in detail below based on the drawings.

In the figure, (1) is a cylindrical body with a lid that has a mouth-shaped cross section, and a certain suction seal body (2) made of rubber or plastic is attached to the periphery of the opening of the cylindrical body (1) with a lid. At the same time, a suction pipe (4) is provided in the ceiling and communicates with a vacuum suction device (not shown) through a rubber hose (3).

Furthermore, a guide member (6) having an annular groove (5) facing outward is provided on the outer peripheral side of the lower portion of the cylindrical body (1) with a lid.
) is fixed to the guide member (6), and a chain (7) is attached to the guide member (6) at an appropriate distance downward from the guide member (6).
) is installed parallel to the The guide member (
There are four turning guide plates (8) (8) in the annular groove (5) of 6).
) (8) (8) are slidably fitted at equal intervals, and each turning guide plate (8) (8) (8) (8) has four arc-shaped rings (9) (9 ) (9) (9) are connected and integrated into one body, and are prevented from slipping out from the annular groove (5).

In addition, the mounting seats (10) (10) are attached to the l pair of swing guide plates (8) (8) located at the target positions in the swing guide plates (8) (8) (8) (8), and one mounting seat (10) is attached with an excitation device (1l) consisting of an air cylinder (or an air vibrator), and the other mounting seat is attached with a gear motor (12) facing downward. A chain wheel (14) that meshes with the chain (7) is attached to the rotating shaft (13).

In the figure, (15) is a hanging device for connecting to a hoisting wire to prevent the device from falling, and (W) is a wall surface. Furthermore, a device (for example, a rotating brush or a shot projecting device) for treating the wall surface (W) is built into the cylindrical body (1) with a lid, but it is omitted in the drawing.

The item configured in this way is equipped with a rubber hose (
3) is communicated with a vacuum suction device (not shown) to create a negative pressure in the space defined by the cylindrical body with lid (1), the suction seal body (2), and the wall surface (W), and the entire device is placed on the wall surface (W). Let it absorb.

In this state, by operating the vibration excitation device (1l) consisting of an air cylinder, the entire device is vibrated diagonally upward to the left in Fig. 2, and is repeatedly oscillated against the wall surface (W), causing the device to move to the left. move in the direction.

During this time, a wall surface treatment device (not shown) provided on the cylindrical body (1) with a lid is operated to continue wall surface treatment. If the wall surface treatment continues in this manner and it becomes necessary to change the moving direction of the apparatus, the gear motor (12) is operated to engage and roll the chain wheel (14) along the chain (6). This allows the turning guide plate (8) (8). (8)
(8) is slid as one body without being in surface contact with the annular groove (5), and along with this, the vibration device (11) is also moved and stopped at an appropriate position.

In this way, the vibration device (1) is applied to the cylindrical body (1) with a lid.
By changing the position of l), the direction of movement of the device is changed and the treatment of the wall surface is continued.

The wall surface is processed in the manner described above, but the mechanism for changing the moving direction of the device is in surface contact with the annular groove (5) of the guide member (6) via the rotation guide plate (8). Since it is supported and slid and rotated while maintaining this state, it has good durability against vibration operations for moving the device and can withstand long-term use.

(Effects) As is clear from the above description, the present invention has a special structure for the moving direction changing mechanism of the device that treats the wall surface while adsorbing it to the wall surface and moving it so that it is in surface contact with the main body part. Since the monument is supported by a holder, it is possible to move the device by suction and change the direction of movement, which is the same as before, and the durability of the device and the durability of the monument against vibrations are greatly improved. It is.
