[0030] In the above technical solution, the plurality of bottom beams are sequentially referred to as the first bottom beam, the second bottom beam, the third bottom beam, etc., and the auxiliary device is explained by taking the welding and fixation of the first bottom beam, the second bottom beam and the third bottom beam as an example.

[0031] After the first bottom beam is welded, the two sets of positioning units are clamped on the first bottom beam and the second bottom beam respectively, the bottom of the mounting block 1 contacts the upper surface of the bottom beam, and the two positioning clamp arms 5 contact the two side walls of the bottom beam respectively, so as to adjust the distance between the first bottom beam and the second bottom beam, and position the second bottom beam with the first bottom beam, so as to quickly position the second bottom beam;

[0032] After the second bottom beam is positioned and welded, when the welding is completed, the positioning unit in contact with the second bottom beam does not move, and the positioning clamp arm 5 in contact with the first bottom beam is lifted upward by the handle member, and the positioning clamp arm 5 slides upward and separates from the first bottom beam, and then the telescopic arm 3 is rotated with the second hinge shaft 4 on the mounting block 1 in contact with the second bottom beam as the rotation axis, so that the mounting block 1 at the other end is separated from the first bottom beam, and the mounting block 1 originally in contact with the first bottom beam is moved to the side of the second bottom beam away from the first bottom beam, and at this time, the moved positioning unit can position the third bottom beam, and the third bottom beam is positioned by relying on the second bottom beam;

[0033] After the mounting block 1 contacts the third bottom beam, the position of the third bottom beam is adjusted, and the pair of positioning clamp arms 5 are driven downward by the handle mechanism so that the pair of positioning clamp arms 5 contact the two sides of the third bottom beam for positioning. The device can position the adjacent bottom beam to be welded by relying on the bottom beam that has been welded, and is easy to use, fast and convenient.

[0034] The length of the telescopic arm 3 can be adjusted, so that the welding distance between two adjacent bottom beams can be adjusted according to actual needs, which is highly practical.

[0035] In a preferred embodiment of the invention, the mounting block 1 is equipped with a spacing adjustment mechanism for driving a pair of positioning clamping arms 5 to move toward or away from each other.

[0036] In the above technical solution, the distance between the pair of positioning clamp arms 5 can be adjusted by the distance adjustment mechanism, so as to be adjusted according to the width of the bottom beam actually welded.

[0037] In a preferred embodiment of the invention, the spacing adjustment mechanism includes a pair of movable arms 6 symmetrically distributed about the first hinge axis 2 and parallel to the first hinge axis 2, each movable arm 6 is fixedly connected with at least one rack 7 whose length direction is perpendicular to the length direction of the movable arm 6 and the length direction of the first hinge axis 2 and is slidably connected to the mounting block 1 along its own length direction, the mounting block 1 is axially connected with at least one connecting shaft 8 parallel to the positioning clamp arm 5, the connecting shaft 8 is fixedly sleeved with a gear 9 on both sides of which are respectively meshed with the racks 7 on a pair of movable arms 6, the mounting block 1 is equipped with a locking member detachably connected to the connecting shaft 8, and the pair of positioning clamp arms 5 slide through the movable arm 6 along a direction perpendicular to the length direction of the movable arm 6.

[0038] In the above technical solution, the locking member is opened, and one of the movable arms 6 is pulled closer to or away from the mounting block 1, driving the corresponding rack 7 to slide on the mounting block 1, and the other meshing rack 7 is driven to slide through the cooperation of the gear 9, thereby driving a pair of movable arms 6 to slide toward or away from each other. After the spacing between a pair of positioning clamp arms 5 is adjusted, the connecting shaft 8 is fixed by the locking member.

[0039] In a preferred embodiment of the invention, the locking member includes a clamping block 10 fixedly mounted on the mounting block 1 and at least one first locking bolt 11, the clamping block 10 is penetrated by a clamping portion whose opposite side walls are in contact with the connecting shaft 8, and the first locking bolt 11 passes through one end of the clamping portion and is threadedly connected to the other end of the clamping portion.

[0040] In the above technical solution, by loosening the first locking bolt 11, the distance between the two side walls of the clamping portion increases, and the connecting shaft 8 can be rotated. By tightening the first locking bolt 11, the two side walls of the clamping portion tightly clamp the connecting shaft 8.

[0041] In a preferred embodiment of the invention, a positioning sleeve 12 is fixedly mounted on the movable arm 6 for the positioning clamp arm 5 to vertically slide through, and a mounting groove 13 with a cross-section larger than that of the positioning clamp arm 5 is penetrated by the movable arm 6, and a first limiting member 14 that can be moved into the mounting groove 13 is connected to the lower end of the positioning clamp arm 5, and a wedge portion 15 is protruding from the lower end of the positioning clamp arm 5.

[0042] In the above technical solution, the inclined wedge portion 15 facilitates the contact between the positioning clamp arm 5 and the side wall of the bottom beam when it slides downward; when it is necessary to rotate the telescopic arm 3 to separate the mounting block 1 from the bottom beam, the positioning clamp arm 5 is lifted upward by the handle mechanism, and the positioning clamp arm 5 slides upward on the positioning sleeve 12 until the first limit member 14 moves into the mounting groove 13 and contacts the positioning sleeve 12.

[0043] In a preferred embodiment of the invention, the telescopic arm 3 includes a pair of first adjusting arms 16 which are arranged in the same length direction and are respectively hinged to the corresponding first hinge shafts 2, and a second adjusting arm 17 which is parallel to the first adjusting arm 16.
