[0029] Please refer to Figure 1 The embodiment provides a stable support special for welding large oil tank, which comprises a supporting frame 1, a hydraulic clamping assembly 2 and a hydraulic tilting assembly 3.

[0030] The supporting frame 1 is used for placing the oil tank, and a plurality of hollow positions 11 are arranged on the supporting frame 1 and arranged relative to the bottom of the oil tank to be welded.

[0031] The hydraulic clamping assembly 2 is arranged around the edge of the supporting frame 1 and is used for clamping and fixing the oil tank.

[0032] The hydraulic tilting assembly 3 is arranged at the bottom of the supporting frame 1.

[0033] The supporting frame 1 can be a rectangular structure. When a large oil tank is placed on the supporting frame 1 by using a crane, the hollowed-out position 11 is aligned with the to-be-welded position at the bottom of the oil tank, so that the supporting frame 1 does not block the to-be-welded position. The hydraulic clamping assembly 2 can fix the large oil tank, and provide good support force through hydraulic driving. After the hydraulic clamping assembly 2 fixes the large oil tank, the hydraulic tilting assembly 3 can tilt the whole supporting frame 1, so that the to-be-welded position at the bottom of the oil tank is raised and faces the worker position, thereby achieving the tilting and displacement of the oil tank, and facilitating the horizontal position welding. Since the supporting frame 1 is connected with the hydraulic tilting assembly 3, and the oil tank is fixed on the supporting frame 1, the situation that the oil tank slips and injures the worker during tilting is avoided. Therefore, compared with the traditional method of supporting the oil tank by using a columnar object to raise the to-be-welded position, the safety factor is higher.

[0034] The supporting frame 1 can be a rectangular structure. When a large oil tank is placed on the supporting frame 1 by using a crane, the hollowed-out position 11 is aligned with the to-be-welded position at the bottom of the oil tank, so that the supporting frame 1 does not block the to-be-welded position. The hydraulic clamping assembly 2 can fix the large oil tank, and provide good support force through hydraulic driving. After the hydraulic clamping assembly 2 fixes the large oil tank, the hydraulic tilting assembly 3 can tilt the whole supporting frame 1, so that the to-be-welded position at the bottom of the oil tank is raised and faces the worker position, thereby achieving the tilting and displacement of the oil tank, and facilitating the horizontal position welding. Since the supporting frame 1 is connected with the hydraulic tilting assembly 3, and the oil tank is fixed on the supporting frame 1, the situation that the oil tank slips and injures the worker during tilting is avoided. Therefore, compared with the traditional method of supporting the oil tank by using a columnar object to raise the to-be-welded position, the safety factor is higher.

[0035] Further, the supporting frame 1 comprises a plurality of cross beams 12 and longitudinal beams 13 arranged in cross, and the hollowed-out position 11 is formed between the cross beams 12 and the longitudinal beams 13.

[0036] The cross beams 12 and the longitudinal beams 13 are arranged in cross perpendicularly to each other, so that the whole supporting frame 1 is in a grid shape, and the hollowed-out position 11 is in the grid-shaped supporting frame 1. It should be noted that, when the large oil tank is placed, in order to ensure that the cross beams 12 or the longitudinal beams 13 do not block the to-be-welded position of the oil tank, a downward curved groove can be arranged on the cross beams 12 or the longitudinal beams 13 at a position opposite to the to-be-welded position, and a reinforcing rib can be arranged below the groove position of the cross beams 12 or the longitudinal beams 13, so as to increase the strength of the beams.

[0037] Further, the hydraulic tilting assembly 3 comprises a plurality of first hydraulic rods 31, and the fixed end and the movable end of the first hydraulic rod 31 are connected with the ground and the supporting frame 1 through a ball hinge 32 respectively.

[0038] The number of the first hydraulic rods 31 can be four, and the four first hydraulic rods 31 can be arranged at the bottom of the four corners of the supporting frame 1 respectively. When two adjacent first hydraulic rods 31 are raised or lowered, the corresponding position on the supporting frame 1 can be raised or lowered, so that the whole supporting frame 1 is tilted.

[0039] Further, the hydraulic clamping assembly 2 comprises a plurality of hydraulic clamping arms arranged at the edges of the support frame 1, the hydraulic clamping arms comprising a swing arm 21, a vertical clamping plate 22 and a second hydraulic rod 23.

[0040] One end of the swing arm 21 is hinged to the support frame 1, and the other end is hinged to the vertical clamping plate 22.

[0041] The fixed end and the movable end of the second hydraulic rod 23 are respectively hinged to the support frame 1 and the swing arm 22.

[0042] The second hydraulic rod 23 can drive the swing arm 21 to swing towards or away from the support frame 1, and the vertical clamping plate 22 always maintains a vertical state when the swing arm 21 swings. When the crane places the large oil tank on the support frame 1, the second hydraulic rod 23 can drive the swing arm 21 to swing inward, so that the vertical clamping plate 22 adheres to the outside of the large oil tank. When a plurality of swing arms 22 simultaneously adhere the vertical clamping plate 22 to the outside of the large oil tank, the hydraulic clamping assembly 2 clamps and fixes the large oil tank.

[0043] Further, the cross beams 12 and the longitudinal beams 13 and the swing arms 21 are I-shaped steel, thereby increasing the support strength.

[0044] Further, the cross beams 12 and the longitudinal beams 13 at the middle part of the support frame 1 extend outward to form a hinge seat 14, and the hinge seat 14 is sequentially hinged with the swing arm 21 and the second hydraulic rod 23 along the length direction thereof.

[0045] Specifically, the longitudinal beams 13 can be 3, and the cross beams 12 can be 5. The support frame 1 is composed of 5 cross beams 12 and 3 longitudinal beams 13. The cross beam 12 and the longitudinal beam 13 at the middle position are longer than those at other positions, thereby extending to form the hinge seat 14. When the swing arm 21 and the second hydraulic rod 23 are hinged on the hinge seat 14, the second hydraulic rod 23 is located outside the swing arm 21.

[0046] Further, the length of the upper end of the vertical clamping plate 22 relative to the hinge is less than the length of the lower end.

[0047] Specifically, the length of the upper part of the vertical clamping plate 22 relative to the hinge is less than the length of the lower part, so that the center of gravity of the vertical clamping plate 22 is always below the hinge, thereby enabling the vertical clamping plate 22 to maintain a vertical state when the swing arm 21 swings.

[0048] Further, the support frame 1 is rectangular, and the first hydraulic rod 31 is arranged at the four corners of the rectangle.

[0049] Principle description:

[0050] The support frame 1 can be a rectangular structure, when a large oil tank is placed on the support frame 1 by using a crane, the hollowed-out position 11 is aligned with the to-be-welded position of the bottom of the oil tank, so as to avoid that the support frame 1 shields the to-be-welded position, the hydraulic clamping assembly 2 can fix the large oil tank, and good supporting force is provided by hydraulic driving, after the hydraulic clamping assembly 2 fixes the large oil tank, the hydraulic tilting assembly 3 can tilt the support frame 1 as a whole, so that the to-be-welded position of the bottom of the oil tank is lifted and faces the worker position, the oil tank is tilted and displaced to realize position welding, since the support frame 1 and the hydraulic tilting assembly 3 are connected together, and the oil tank is fixed on the support frame 1, the situation that the oil tank slips and injures the worker when the oil tank is tilted is avoided, and therefore, compared with the traditional mode of supporting the oil tank to lift the to-be-welded position by using a columnar object, the safety factor is higher.
