Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a flue cleaning device and a flue cleaning method.

[0002]

2. Description of the Related Art In recent years, various apparatuses have been proposed to remove dusts such as black soot and the like adhering to the inside of a stack and a flue, which are increasing in height. For example, there is a method in which a gondola that can be moved up and down is suspended from above the chimney, and a cleaning worker gets into the gondola to scrape dust. On the other hand, in consideration of the safety of workers, an unmanned cleaning device is also provided.For example, a cleaning tool such as a brush is provided around a freely movable gondola, and a brush is provided by moving the gondola up and down. However, there is a configuration in which the inside of the flue is cleaned.

[0003]

In the above-described cleaning device, it is inevitable to reduce the cleaning efficiency by the brush.
Problems such as a decrease in work efficiency due to uneven cleaning may occur. It is an object of the present invention to provide a flue cleaning device that makes cleaning of a flue unmanned and has high working efficiency.

[0004]

Means for Solving the Problems and Action / Effect To solve the above problems, a flue cleaning device of the present invention comprises a suspending means, and a suspending main body which is suspended vertically by the suspending means. A plurality of cleaning means disposed on the outer peripheral surface of the hanging main body and including a portion in contact with the inner surface of the flue; and arranged on the outer peripheral surface of the hanging main body, and rotating the hanging main body in the circumferential direction. And a torque generating means for generating torque for the purpose.

[0005] According to the above-mentioned flue cleaning device, the plurality of cleaning means arranged on the outer peripheral surface of the hanging main body and abutting on the inner surface of the flue, scratches the inner surface of the flue as the hanging main body moves up and down. Cleaning), but in the present invention,
Since the torque generating means is attached to the suspension main body, the cleaning means moves in the circumferential direction in addition to the elevating direction to scratch the inner surface of the flue. By moving in the vertical direction and in the circumferential direction, the inner peripheral surface of the flue is efficiently cleaned, and uneven cleaning is less likely to occur due to the rotation in the circumferential direction. It can be shortened.

[0006] Such a torque generating means is configured to be in contact with the inner surface of the flue. When the suspension main body is moved up and down, the abutting portion receives resistance from the inner surface of the flue, and is rotated by the resistance. A configuration in which a force is generated can be adopted. Specifically, an inclined surface inclined at a predetermined angle with respect to the lifting / lowering direction of the suspension body is formed in the torque generating means, and the inclined surface receives resistance from the inner surface of the flue as the suspension body moves up and down. A rotational force may be generated.

On the other hand, the cleaning means may be constituted as a torque generating means, and a rotational force may be generated when the cleaning means contacts the inner surface of the flue. In this case, the cleaning means comes into contact with the inner surface of the flue while ascending and descending together with the suspension main body portion, thereby receiving a resistance from the inner surface of the flue and generating a torque by the resistance. For example, at the time of cleaning, the inclined surface moves up and down while scratching dust and the like, but resistance is generated on the inclined surface from the dust, and a rotational force corresponding to the inclination angle of the inclined surface is generated by the resistance in the hanging main body, The flue cleaning device rotates in the flue circumferential direction around the suspension shaft.

[0008] By the rotation of the cleaning device accompanying the elevation, a plurality of cleaning means arranged on the outer peripheral surface of the suspension main body efficiently clean the inner peripheral surface of the flue. In addition, since the configuration is such that the suspension body rotates naturally as it moves up and down, there is no need to provide a special drive unit such as a motor for rotating the suspension body, so that the cleaning device can be made lightweight and inexpensive. Can be provided.

The hanging means can be exemplified by a method of hanging a hanging body by a crane truck or the like via a wire or the like, and the cleaning means means a tool for cleaning. For example, brush (brush), cloth,
It is composed of a sheet scraper or the like.

[0010] The torque generating means can be spirally attached to the outer peripheral surface of the suspension main body. By attaching the torque generating means to the suspension main body in a spiral shape, it becomes possible to more effectively generate the rotational force to the cleaning device generated by the resistance received from the inner peripheral surface of the flue.

Further, the cleaning means comprises a mounting support attached to the suspension main body, and a cleaning main body provided on the tip side of the mounting support, and the cleaning main body is used as torque generating means. be able to. The cleaning body is
For example, it is composed of a brush (brush), cloth, sheet scraper, or the like. In this case, for example, the inclined surface can be formed on the cleaning main body, and the cleaning device rotates on its own due to the resistance applied to the inclined surface. The cleaning body provided on the tip side of the mounting support slides on the inner surface of the flue in the circumferential direction by rotation, so that dust and the like adhering to the inner surface of the flue can be effectively and uniformly removed. is there.

On the other hand, the mounting support portion may be helically attached to the suspension main body, and the cleaning main body may form the inclined surface along the helical shape. Also in this case, the spiral inclined surface formed by the cleaning main body receives resistance from the inner surface of the flue as it moves up and down, and the cleaning device rotates by its resistance. The inclined surface formed by the cleaning body (cleaning means) can be adjusted to an arbitrary angle, and in this case, the rotation speed is adjusted according to the angle. In addition, it is preferable that the number of the mounting support portions attached to the hanging main body portion is as large as possible. In this case, the area of the inclined surface formed by the cleaning main body portion provided at the tip becomes large, so that the inner surface of the flue And the rotation efficiency is improved.

The cleaning main body includes a flexible member such as a brush, and an outer peripheral portion of the cleaning main body formed of the flexible member forms a large-diameter portion larger than the inner diameter of the flue. Wherein the flexible member is bent and deformed, whereby the flue cleaning device is inserted into the flue, and the cleaning body is biased toward the inner surface of the flue based on the bent deformation. It can be. In this case, the inner surface of the flue is effectively scratched and cleaned by the urging force of the cleaning main body toward the inner surface of the flue caused by the deformation of the cleaning main body, and the cleaning main body is removed from the inner surface of the flue. Since a large resistance force is received, a large torque for rotating the suspension body is generated. As a result, a large circumferential scratching effect is produced on the inner surface of the flue, and the efficiency of cleaning the inner surface of the flue is further improved.

Next, the suspension main body can be provided with a load applying means for applying a constant load to the suspension main body downward in the direction of suspension. The suspension body is suspended by a crane truck or the like via suspension means such as a wire.When the cleaning device is inserted into the chimney, the load applying means is provided in the suspension body. The position of the center of gravity is stabilized, and the insertion becomes easy. Further, by providing the load applying means, the suspension state of the suspension main body during the cleaning operation is stabilized, and the lifting operation can be performed smoothly.

The lower part of the suspension main body in the suspension direction includes:
A taper that tapers can be formed. By thus tapering the lower part of the suspension main body, the cleaning device can be more easily inserted into the chimney.
Further, the suspension main body may be provided with a light emitting unit that emits light from the lower side in the suspension direction of the suspension main body. The light emitted by the light emitting means is sensed by a sensor (monitor) provided inside the chimney, for example (including artificial visual sensing), and the sensed information is transmitted to an operator (driver) such as a crane truck. By doing so, the light emitting means can be an insertion assisting means when inserting the flue cleaning device into the chimney.

On the other hand, on the outer peripheral surface of the suspension main body portion, a rotatable auxiliary roller that slides and abuts on the flue surface to be cleaned can be provided. When the auxiliary roller is in sliding contact with the inner peripheral surface of the flue, the cleaning device can be smoothly moved up and down and inserted into the chimney, and the swing of the cleaning device in the suspended state can be prevented or suppressed. Becomes

In the above configuration, the cleaning means can be detachably attached to the suspension main body. For example, a cleaning means having a cleaning body such as a brush may be unusable due to wear due to repetitive cleaning work. Can be replaced, and it becomes possible to cope with the unusable situation as described above. In addition, since the detachable configuration enables the length of the mounting support portion to be changed in various ways, the outer diameter of the stack cleaning device can be made to correspond to, for example, various chimneys having different stack inner diameters. It becomes possible.

On the other hand, the mounting support portion of the cleaning means can be configured to be extendable and contractible. In this case, by expanding and contracting the mounting support portion corresponding to the inside diameter of the stack such as a chimney, the stack can be used for stacks having several different inside diameters. Examples of such an extendable structure include a method in which the mounting support portion is configured to be slidable stepwise, and a method in which an elastic member or the like is provided in the mounting support portion.

For example, when a part or the whole of the mounting support portion is made of an elastic member, even if one chimney has a different inner diameter in the height direction (a tapered chimney having a tapered shape, etc.), the elastic member can be used. Using the elastic deformation, it is possible to effectively clean the inner surface of the flue. Specifically, the mounting support corresponding to the maximum inner diameter of the chimney is attached to the suspension main body,
At the position where the inner diameter of the chimney becomes smaller, the cleaning member is reduced in diameter by the elastic deformation of the elastic member of the mounting support, thereby effectively cleaning the inner surface of the flue. The elastic return force works to clean the inside of the flue.

Further, in the method of cleaning a flue according to the present invention, the cleaning means which is lowered and / or raised while being in contact with the inner surface of the chimney is rotatably supported around the axis of the chimney, and the cleaning means descends inside the chimney. And / or determine the shape or arrangement of the cleaning means such that the resistance of the chimney inner surface causes its rotation as it ascends, whereby the cleaning means lowers and / or raises itself on the chimney inner surface. The method is characterized in that the deposits are rotated to remove the deposits on the inner surface of the chimney. With such a method, the deposits such as dust on the inner surface of the chimney can be easily and effectively removed.
