[0069] Furthermore, a threaded hole 1211 is provided inside the slider 121;

[0070] The rotating shaft 112 and the threaded holes 1211 corresponding to the two groups of the sliders 121 are respectively provided with positive threads 1121 and negative threads 1122 for driving the sliders 121 to move synchronously in the opposite direction.

[0071] Furthermore, both ends of the clamping block 124 are respectively provided with inclined surfaces 125 adapted to the oblique rod 101 for clamping the oblique rod 101;

[0072] The clamping block 124 is configured as a plane at one end opposite to the first push rod 123 , and is used to clamp the straight rod 102 .

[0073] Wherein, both ends of the clamping block 124 and located at the lower part of the inclined surface 125 are fixedly connected with a first support plate 1251 for bottom support of the inclined rod 101 in a clamped state;

[0074] A second support plate 1252 is fixedly connected to the lower portion of one end of the clamping block 124 opposite to the first push rod 123 , so as to provide bottom support for the straight rod 102 in a clamped state.

[0075] As an improvement, Figure 4 As shown, the tightening unit 2 includes:

[0076] The cylinder 21 is installed on the upper end of the adjusting block 111;

[0077] A lifting rod 22, fixedly connected to the upper end of the cylinder 21;

[0078] The second push rod 23 is provided with two groups, which are respectively fixedly connected to the two ends of the lifting rod 22. The outer side of the second push rod 23 is provided with a guide sleeve 231 for guiding the movement of the second push rod 23. The guide sleeve 231 is fixedly connected to one end of the adjustment block 111;

[0079] The pressure rod 24 is fixedly connected to the lower end of the second push rod 23 and is used to tighten the straight rod 102 and the oblique rod 101 in the clamped state.

[0080] It should be supplemented that the oblique rod 101 in the present invention is X-shaped.

[0081] It should be noted that: Figure 2-5As shown, in the specific implementation process of the present invention, the flange 1133 is connected to the lower end of the lifting and adjusting arm of the crane. When the inclined rod 101 is hoisted and welded, the adjusting block 111 is driven to the upper part of the inclined rod 101 by controlling the crane, so that the two groups of clamping blocks 124 are respectively located on both sides of the inclined rod 101 and the first support plate 1251 is located below the inclined rod 101, and the motor at one end of the driving gear 115 is started. The motor drives the driven gear 114 to rotate through the driving gear 115, and the driven gear 114 drives the rotating shaft 112 to rotate. The rotating shaft 112 drives the slider 121 to move relatively along the rotating shaft 112 under the action of the thread tangential force between the positive thread 1121 and the negative thread 1122 and the corresponding threaded hole 1211. The slider 121 moves relative to the rotating shaft 112 through the first top The rod 123 drives the clamping block 124 to move toward the oblique rod 101, and the clamping block 124 drives the inclined surface 125 to clamp the side of the oblique rod 101, thereby completing the left and right positioning of the oblique rod 101. Subsequently, the cylinder 21 is started, and the cylinder 21 drives the second push rod 23 to move downward along the guide sleeve 231 through the lifting rod 22. The second push rod 23 presses the oblique rod 101 downward through the pressing rod 24, so that the oblique rod 101 is pressed against the upper end of the first supporting plate 1251, thereby completing the up and down positioning of the oblique rod 101. Finally, the positioned oblique rod 101 is lifted by controlling the crane and sent to between the two groups of support beams 100 for welding. Thus, by positioning the oblique rod 101 before hoisting and welding, it is avoided that the welding process is difficult to control, thereby improving the welding efficiency.

[0082] like Figure 6As shown, similarly, when the straight rod 102 is hoisted and welded, the adjusting block 111 is driven to the upper part of the straight rod 102 by controlling the crane, so that the two groups of clamping blocks 124 are respectively located on both sides of the straight rod 102 and the second supporting plate 1252 is located below the straight rod 102, and the motor at one end of the driving gear 115 is started, and the motor drives the driven gear 114 to rotate through the driving gear 115, and the driven gear 114 drives the rotating shaft 112 to rotate, and the rotating shaft 112 drives the slider 121 to move relatively along the rotating shaft 112 under the action of the thread tangential force between the positive thread 1121 and the negative thread 1122 and the corresponding threaded hole 1211, and the slider 121 drives the clamping block 124 toward the straight rod 102 through the first push rod 123. The straight rod 102 is moved so that the clamping block 124 clamps the side of the straight rod 102, thereby completing the left and right positioning of the straight rod 102. Subsequently, the cylinder 21 is started, and the cylinder 21 drives the second push rod 23 to move downward along the guide sleeve 231 through the lifting rod 22. The second push rod 23 presses the straight rod 102 downward through the pressing rod 24, so that the straight rod 102 is pressed against the upper end of the second support plate 1252, thereby completing the upper and lower positioning of the straight rod 102. Finally, the straight rod 102 after positioning is lifted by controlling the crane and sent to between the two groups of support beams 100 for welding. In this way, the straight rod 102 is positioned before lifting and welding, and it can be used for positioning both the straight rod 102 and the inclined rod 101.
