Description

Description: FIELD OF THE INVENTION The present invention relates to a core lifting device for an oil combustor having a lever-type operating portion.

[Prior Art] As a core lifting device for an oil combustor, a lever-type core lifting device has been put into practical use in place of the conventional dial type. The lever type core up / down device has a narrow operating range of the operating lever.
Since the rotation angle of the vertical axis of the core is narrow, the accuracy of each component is required. However, the narrow operating range of the operating lever is preferred because it allows one-touch centering operation.

[Problems to be Solved by the Invention] By the way, the lever-type core up / down device capable of lifting the core by one-touch pushing operation enables one-touch operation by narrowing the moving distance of the operation lever and the core vertical axis as described above. However, when adjusting the combustion amount using the operating lever, the core height changes significantly by simply moving the operating lever, making fine adjustment of the combustion amount unsuitable.

Since the combustion cylinder of the conventional core up-down type oil combustor could hardly adjust the combustion amount, and there was almost no opportunity to adjust the combustion amount, this point was not taken up as a problem even in the lever system, but recently As a result of the development of a large number of combustion cylinders with adjustable combustion amounts, it began to be recognized as a serious drawback.

[Means for Solving the Problem] The present invention relates to a core up / down device that enables a fine drive operation of an operation lever, and includes an operation lever 2 for rotating a core up / down shaft 1, and an operation lever 2 attached to the operation lever 2. Drive pin 3 and a plurality of drive levers 5 that rotate about the same support shaft 4 are provided, and the drive lever 5 faces the drive pin 3 of the operation lever 2 that is rotated to the center-up position. The notch 6 is provided so that the inner portion of the V-shaped notch 6 abuts the drive pin 3 when the drive lever 5 is rotated, and the shape of the V-shaped notch 6 is different for each of the plurality of drive levers 5. When the V-shaped notch 6 of the selected one drive lever 5 is rotated toward the drive pin 3, the end face of the V-shaped notch 6 moves the operation lever 2 through the drive pin 3 It is to rotate a small angle.

Further, an L-shaped bent portion 7 is formed at the ends of the plurality of drive levers 5 at different bending positions, and the operation panel that reaches the L-shaped bent portion 7 on the front panel 8 of the oil combustor. A plurality of sheets 9 are arranged side by side, and the operation plate 9 of the front panel 8 allows the drive lever 5 to rotate via the L-shaped bent portion 7.

[Explanation of Action] When adjusting the combustion amount during combustion of the oil combustor, when one of the plurality of drive levers 5 is rotated around the support shaft 4, the drive lever 5 is turned into a V shape. The notch 6 moves toward the drive pin 3. The drive pin 3 located in the V-shaped notch 6 from the front opening of the V-shaped notch 6 is pushed by the end surface of the V-shaped notch 6 and rotates the operating lever 2 to rotate the V-shaped notch 6
The core vertical shaft 1 is rotated so that the amount of combustion is determined by the drive lever 5 and is located in the inner part of the core. Therefore, it is possible to set a plurality of combustion amounts by preparing a plurality of drive levers 5 that are gradually changed to positions at the inner part of the V-shaped notch 6.

Further, if a plurality of operation plates 9 are arranged side by side on the front panel 8 of the oil combustor, and the operation plates 9 are set so as to reach the L-shaped bent portion 7 at the end of the operation lever 5, the operation of the front panel 8 By pushing the plate 9, the drive lever 5 moves via the L-shaped bent portion 7, and the combustion amount of the oil combustor can be changed.
