Description

Technical Field

[0001] The present invention relates to a chimney soot removal machine that can remove soot inside a chimney without manual labor. The cleaning machine itself can move up and down, and a brush for removing soot touches the inner wall of the chimney.

Background Art

[0002] Conventionally, for chimney soot removal, a device has been proposed in which a rope is lowered from the chimney's smoke outlet, and a machine that rotates a brush for removing soot on the inner wall of the chimney is suspended from the rope. The position of the part for removing soot inside the chimney is determined at the hanging tip of the rope. Therefore, a worker who operates the rope is required, and there is also a dangerous operation of transporting the hanging rope to the top of the chimney.

[0003] In Patent Document 1, a winch is fixed to the chimney smoke outlet, and an electric motor of a chimney cleaning machine suspended from a winch wire hook is driven, and soot is removed with a brush. It has a complicated mechanism configuration and a dangerous operation of fixing a winch to the high chimney smoke outlet before work, and also requires an operator to operate the winch. An automatic chimney cleaning machine has been proposed.

[0004] In Patent Document 2, a winch is fixed to the top of the chimney, and an automatic chimney cleaning machine is proposed, which uses a rotating brush attached to two upper and lower rotating substrates that rotate in opposite directions and are driven at a low speed by a motor of a suspended cleaning machine to remove soot from the inner wall of the chimney.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Conventional chimney cleaning was carried out by suspending from the upper part of the chimney. Therefore, it was necessary for the worker to climb up to the upper part of the chimney, which was very dangerous. Furthermore, a great deal of work was required to provide a support structure for hanging a winch on the upper part of the chimney. On the other hand, since the inner diameter of the chimney was different between the upper and lower parts, there was no device that could be dealt with by a simple mechanism. Therefore, an object of the present invention is to eliminate dangerous work and to facilitate the work by allowing the cleaning machine itself to move up and down and the brush to rub against the inner wall of the chimney by a simple mechanism.

Means for Solving the Problems

[0007] In order to solve the above problems, the inventor invented the following means. The invention of Means 1 is a chimney soot cleaning machine comprising a support body, a lifting guide, and a soot scraping tool, the lifting guide is provided around the support body, the lifting guide comprises an arm A, an arm B, a telescopic member, and a rotating body, the rotating body is located at the connection part of the arm A and the arm B, the telescopic member is connected between the arm A and the arm B, whereby the rotating body can follow the inner diameter of the chimney and be displaced in the diameter direction of the chimney A chimney soot cleaning machine characterized by the above is provided.

[0008] The rotating body may have any structure as long as it can contact the inner wall of the chimney and move up and down. The optimal structure is preferably one with a sharp blade tip. Incidentally, the rotating body is rotated by a driving device such as a motor, and the position of the motor may be anywhere. A preferable position is near the connection part of the arm A and the arm B. The strut is preferably composed of a strut pipe. However, for example, when the inner diameter of the chimney is large, it may be a shaped body including a strut pipe as shown by 1 in Fig. 5.

[0009] The lifting guide has the characteristic that the telescopic member between the arm A and the arm B causes the force with which the lifting guide presses against the inner wall of the chimney to change, and can continuously correspond to the inclination of the thickness from the thickness of the upper part of the chimney to the thickness of the top part where the smoke is discharged. In addition, the telescopic member may be any material as long as stress acts in the pulling direction. For example, a hydraulic cylinder, rubber, or a spring is preferable. It is shown as a spring in the drawings. The number of the lifting guides should be at least three. Considering safety, it is safer to install six in a symmetric arrangement of three installations.

[0010] The invention of means 2 provides a chimney soot cleaning machine according to means 1, characterized in that the cleaning tool support arm of the soot cleaning tool is provided with a joint member composed of a bending mechanism as shown in Fig. 2, for example.

[0011] The joint member has the characteristic of being able to correspond to various inner diameters because the inner diameter of the chimney is different between the upper and lower parts, and is a chimney soot cleaning machine.

Effect of the Invention

[0012] The remarkable effect of the present invention is about how to overcome the automatic lifting and lowering of the cleaning machine itself along the inner wall of the chimney. The automatic lifting and lowering of the cleaning machine can prevent the operator from falling from a high place, and it is a simple and inexpensive chimney soot cleaning machine that can be easily configured.

Embodiments for Carrying Out the Invention

[0014] The present invention will be described with reference to the drawings, but the present invention is not limited thereto.

[0015] In FIG. 1, a side view of the entire chimney soot cleaner is depicted. At the lower part of the support body (1), a member lifting guide (4) necessary for lifting and lowering the chimney inner wall is arranged. The lifting guide (4) includes an arm A (401), an arm B (402), a telescopic member (404), a lifting electric motor (9), and a rotating body (403). The force with which the lifting guide (4) presses against the chimney inner wall is the contraction force that connects to both ends of the telescopic member (404) and narrows the separation distance between the arm A (401) and the arm B (402), which changes into the force pressing against the chimney inner wall and serves as the support necessary for lifting and lowering. It is a chimney soot cleaner that lifts and lowers by rotating the lifting electric motor (9) forward and backward. Also, a soot removal member is depicted at the upper part of the support body (1), and a cleaning tool electric motor (10), a cleaning tool support arm (5), a joint member (6), and a brush (7) are arranged. The joint member (6) is located approximately in the middle of the cleaning tool support arm (5) and has a structure that can bend and adapt to changes in the diameter of the chimney.

[0016] FIG. 2 is a cross-sectional view taken along line A-A of the soot removal part at the upper part of the support body (1), showing the cleaning tool electric motor (10), the cleaning tool support arm (5), the joint member (6), and the brush (7). By installing the joint member (6) in the middle of the cleaning tool support arm (5), it is adapted to changes in the chimney diameter.

[0017] Figure 3 is a sectional view taken along line B-B of the lifting guide (4) part at the lower part of the support column (1). It is in a fixed state from the support column (1) which is the center of the sweeper, to the inner wall of the chimney, fixed by the lifting guide (4) arranged at the apex of an equilateral triangle. The lifting guide (4) is composed of an arm A (401), an arm B (402), a telescopic member (404), a lifting electric motor (9), and a rotating body (403). A lifting electric motor (9) and a rotating body (403) are provided at the intersection of the arm A (401) and the arm B (402). Due to the contraction force of the telescopic member (404), the chimney soot cleaning machine can move up and down with the tension force against the inner wall of the chimney, the rotation of the lifting electric motor (9), and the rotating body (403).

[0018] Figure 4 is a sectional view taken along line B=B of the lifting guide (4) part at the lower part of the support column (1). The lifting guide (4) is in a fixed state from the support column (1) for lifting to the inner wall of the chimney, arranged at the apex of a regular hexagon. Centered on the support column (1), there are two sets of the equilateral triangle-shaped lifting guides (4) in Figure 3 symmetrically. When the lifting guide (4) has three legs, if the tension force of one leg is insufficient, it will fall. However, in the case of six legs, even if the tension force of one of the lifting guides (4) is insufficient, the chimney soot cleaning machine will not fall and can be safely lifted and lowered by the other five lifting guides (4).

[0019] Figure 5 shows that when the chimney is thick, the thickness of the support column (1) is composed of the thickness obtained by subtracting the horizontal dimension of the lifting guide (4). By providing the lifting guide (4) at the vertices of a polygon on the support column (1), the multiple lifting guides (4) support the support column (1) and enable lifting and lowering.

[0020] Figure 6 shows that the lifting guide (4) is installed in two stages to ensure the center position of the support column (1) in the inner wall of the chimney, and due to the support column (1) maintaining the center position, the lifting movement is carried out by the entire lifting guide (4), and each lifting electric motor is synchronized to enable lifting and lowering.

[0021] Fig. 7 shows that the lifting guide (4) using the wheels (12) on the rotating body (403) of the lifting guide is installed in two stages. Wheels (12) are installed instead of the upper rotating body (403). The support body (1) ensures the core position of the chimney inner wall, and the lifting movement is carried out by the entire lifting guide (4), and the electric motors for lifting synchronize to enable lifting and lowering.

[0022] When the chimney itself is made of steel, it is also possible to fix a magnet instead of the cutting edge of the rotating body (403) and automatically lift and lower the sweeper by the attractive force between the magnet and the iron. By the way, by providing sensors for detecting the upper and lower ends of the chimney and controlling the forward and reverse rotations of the electric motor for lifting, it is possible to prevent falling accidents from high places. That is, by using this chimney soot cleaning machine, it can be lifted and lowered automatically, so that workers are no longer required.

Industrial Applicability

[0023] Recently, the number of concrete chimneys has also been decreasing. The people who clean the chimney soot are getting older, and the number of people involved is also decreasing. The era when a chimney soot cleaning machine that can lift and lower itself inside the chimney and clean the soot without having to climb the chimney is in urgent need is approaching.
