[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following description, with reference to the accompanying drawings, describes a support device for a large-diameter, atmospheric pressure cutter head according to an embodiment of the present invention. For example... Figures 1 to 6 As shown, the support device for a large-diameter atmospheric pressure cutter head according to an embodiment of the present invention includes a base plate 1, a first support column 2, and a second support column 3.

[0037] The thickness direction of the base plate 1 is vertical. The first support column 2 and the second support column 3 are both provided on the upper surface of the base plate 1, and both the first support column 2 and the second support column 3 extend vertically. The top of the first support column 2 has a first support surface 22 facing upward, and the top of the second support column 3 has a second support surface 32 facing upward. The first support surface 22 is located above the second support surface 32, and the distance between the first support surface 22 and the second support surface 32 in the vertical direction is a first preset value.

[0038] According to an embodiment of this utility model, the support device for a large-diameter atmospheric pressure cutter head includes a first support column 2 and a second support column 3 mounted on a base plate 1. The base plate 1 has a large contact area with the ground, preventing the first support columns 2 and 3 from damaging the ground and causing tilting. The base plate 1 supports the first support columns 2 and 3, ensuring stability when supporting the large-diameter atmospheric pressure cutter head. The first support surface 22 is located above the second support surface 32, and the vertical distance between the first support surface 22 and the second support surface 32 is a first preset value. Thus, after the first support surface 22 contacts the large-diameter atmospheric pressure cutter head and the first support column 2 supports it, a jack can be placed on the second support surface 32 of the second support column 3. The extension length of the jack can then be adjusted to facilitate the cooperation between the second support column 3 and the jack for position adjustment and support of the large-diameter atmospheric pressure cutter head.

[0039] Therefore, the support device for large-diameter atmospheric pressure cutter discs according to the embodiments of the present invention facilitates the support of large-diameter atmospheric pressure cutter discs.

[0040] like Figures 1 to 6 As shown, the support device for a large-diameter atmospheric pressure cutter head according to an embodiment of the present invention further includes a reinforcing plate, which is connected to at least two of the base plate 1, the first support column 2, and the second support column 3. The reinforcing plate can support the first support column 2 and the second support column 3 to improve the structural strength of the support device for the large-diameter atmospheric pressure cutter head, thereby improving the stability of the first support column 2 and the second support column 3 when supported.

[0041] like Figures 1 to 4 As shown, in some embodiments, the reinforcing plate includes a first reinforcing plate 41, a second reinforcing plate 42, and an intermediate reinforcing plate 43.

[0042] Multiple first reinforcing plates 41 are spaced apart and arranged around the periphery of the first support column 2. Each first reinforcing plate 41 is connected to the outer peripheral surface of the first support column 2 and the upper surface of the base plate 1. Multiple second reinforcing plates 42 are spaced apart and arranged around the periphery of the second support column 3. Each second reinforcing plate 42 is connected to the outer peripheral surface of the second support column 3 and the upper surface of the base plate 1. An intermediate reinforcing plate 43 is disposed between the first support column 2 and the second support column 3. The intermediate reinforcing plate 43 is connected to the upper surface of the base plate 1, the outer peripheral surface of the first support column 2, and the outer peripheral surface of the second support column 3. Specifically, the multiple first reinforcing plates 41 are disposed at the lower part of the periphery of the first support column 2 to support the first support column 2. The multiple second reinforcing plates 42 are disposed at the lower part of the periphery of the second support column 3 to support the second support column 3.

[0043] In some embodiments, the thickness direction of the first reinforcing plate 41 and the second reinforcing plate 42 is a first direction, and the thickness direction of the intermediate reinforcing plate 43 is a second direction. Any two of the first direction, the second direction, and the up-down direction are perpendicular to each other. The first direction can be a left-right direction, and the second direction can be a front-back direction. For example, the thickness direction of the first reinforcing plate 41 and the second reinforcing plate 42 is both a left-right direction, and the thickness direction of the intermediate reinforcing plate 43 is a front-back direction.

[0044] The first support column 2 and the second support column 3 are spaced apart in a first direction. Specifically, the first direction is the length direction of the large-diameter atmospheric pressure cutter head, and the first support column 2 and the second support column 3 are spaced apart in the length direction of the large-diameter atmospheric pressure cutter head. For example, the first support column 2 and the second support column 3 are spaced apart in the left-right direction.

[0045] There are two first reinforcing plates 41, which are arranged on both sides of the first support column 2 in the second direction, and the dimensions of the first reinforcing plates 41 increase downward in the second direction. For example, the first reinforcing plates 41 are trapezoidal. The two first reinforcing plates 41 are arranged on both sides of the first support column 2 in the front-rear direction, and the dimensions of the first reinforcing plates 41 in the front-rear direction increase downward.

[0046] There are two second reinforcing plates 42, which are arranged on both sides of the second support column 3 in the second direction, and the dimensions of the second reinforcing plates 42 increase downward in the second direction. For example, the second reinforcing plates 42 are trapezoidal. The two second reinforcing plates 42 are arranged on both sides of the second support column 3 in the front-rear direction, and the dimensions of the second reinforcing plates 42 in the front-rear direction increase downward.

[0047] The intermediate reinforcing plate 43 is located between the first support column 2 and the second support column 3 in the first direction. This allows the first support column 2 and the second support column 3 to be connected to the base plate 1, further increasing structural stability. For example, the intermediate reinforcing plate 43 can be located between the first support column 2 and the second support column 3 in the left-right direction.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the reinforcing plate further includes a top reinforcing plate 44, which is located above the intermediate reinforcing plate 43. The top reinforcing plate 44 is positioned between the first support column 2 and the second support column 3 in a first direction, and is connected to the top of the outer peripheral surface of the first support column 2 and the outer peripheral surface of the second support column 3. Specifically, the thickness direction of the top reinforcing plate 44 is a second direction, and the top reinforcing plate 44 is used to connect to the upper middle part of the first support column 2 and the upper part of the second support column 3 to further increase the structural strength. For example, the top reinforcing plate 44 is positioned between the first support column 2 and the second support column 3 in a left-right direction, and the thickness direction of the top reinforcing plate 44 is a front-back direction.

[0049] In some embodiments, the top of the first support column 2 is provided with a first top plate 21 whose thickness direction is vertical, and the upper surface of the first top plate 21 forms a first support surface 22. The top of the second support column 3 is provided with a second top plate 31 whose thickness direction is vertical, and the upper surface of the first top plate 21 forms a second support surface 32.

[0050] Specifically, both the first top plate 21 and the second top plate 31 are rectangular plates, and both the first support surface 22 and the second support surface 32 are rectangular planes facing upwards. The outer perimeter of the cross-sections of the first support column 2 and the second support column 3 are circular. In the cross-section perpendicular to the vertical direction, the projection of the first support column 2 is located inside the outer perimeter of the projection of the first top plate 21, and the projection of the second support column 3 is located inside the outer perimeter of the projection of the second top plate 31. In other words, the side length of the first top plate 21 is greater than the outer diameter of the first support column 2, and the side length of the second top plate 31 is greater than the outer diameter of the second support column 3. This increases the area of ​​the first support surface 22 and the second support surface 32, thereby increasing the stability during support. For example, both the first support column 2 and the second support column 3 are made of steel pipes, with the first support column 2 having a reinforcing rib connected to the first top plate 21, and the second support column 3 having a reinforcing rib connected to the second top plate 31.

[0051] In some embodiments, the first support column 2 is provided with first fork plates 23 on both sides in the second direction, and the thickness direction of the first fork plates 23 is the vertical direction. And / or, the second support column 3 is provided with second fork plates 33 on both sides in the second direction, and the thickness direction of the second fork plates 33 is the vertical direction. Specifically, the first support column 2 is provided with first fork plates 23 on both sides in the second direction, and the thickness direction of the first fork plates 23 is the vertical direction. And / or, the second support column 3 is provided with second fork plates 33 on both sides in the second direction, the thickness direction of the second fork plates 33 being the vertical direction, including: a) the first support column 2 is provided with first fork plates 23 on both sides in the second direction (front-rear direction), so that the forklift can lift the first fork plates 23 (and the second top plate 31) to move the support device for the large-diameter atmospheric pressure cutter head; b) the second support column 3 is provided with second fork plates 33 on both sides in the second direction (front-rear direction), so that the forklift can lift the second fork plates 33 to move the support device for the large-diameter atmospheric pressure cutter head; c) the first support column 2 is provided with first fork plates 23 on both sides in the second direction (front-rear direction), and the second support column 3 is provided with second fork plates 33 on both sides in the second direction (front-rear direction), so that the forklift can lift the first fork plates 23 and the second fork plates 33 to move the support device for the large-diameter atmospheric pressure cutter head.

[0052] In some embodiments, the first top plate 21 is provided with a first hanging hole located outside the first support column 2, and the second top plate 31 is provided with a second hanging hole located outside the second support column 3. Specifically, the first hanging hole is located at the corner of the first top plate 21, and the second hanging hole is located at the corner of the second top plate 31, so that shackles can be hung on the first and second hanging holes, thereby facilitating the lifting of the support device for the large-diameter atmospheric pressure cutter head by a crane.

[0053] In some embodiments, the first preset value is greater than or equal to 0.4 meters and less than or equal to 1 meter. That is, the height difference between the first support surface 22 and the second support surface 32 is greater than or equal to 0.4 meters and less than or equal to 1 meter. For example, the height difference between the first support surface 22 and the second support surface 32 is 0.5 meters, 0.6 meters, 0.7 meters, 0.8 meters, or 0.9 meters.

[0054] like Figures 1 to 4 As shown, the vertical dimension between the top surface of the first top plate 21 and the bottom surface of the bottom plate 1 is 0.95 meters, the vertical dimension between the top surface of the second top plate 31 and the bottom surface of the bottom plate 1 is 0.5 meters, and the vertical dimension between the top surface of the first fork plate 23 and the bottom surface of the bottom plate 1 is 0.5 meters.

[0055] like Figure 5 and Figure 6 As shown, the vertical dimension between the top surface of the first top plate 21 and the bottom surface of the bottom plate 1 is 1.35 meters, and the vertical dimension between the top surface of the second top plate 31 and the bottom surface of the bottom plate 1 is 0.9 meters.
