Jig for rapidly welding a tarpaulin receiving and keeping carrier of truck

The present invention relates to a jig for quickly welding a truck carrier for storing and storing a waterproof sheet, and to fix the pipe member, which is a component of the truck carrier in the form of a lattice basket in the form of a grid, to rotate about a vertical axis and to rotate the horizontal axis It relates to a jig that enables to quickly weld the connections between the components while turning relative to.

The truck carrier 10 in the form of a lattice basket has two leg pipes arranged parallel to each other and having portions 11a and 11a parallel to the truck driver's seat plate 20, as shown in FIG. 11, 11); A group of N-shaped base tubes (12, 12, .....) welded to the parallel portions (11a, 11a) and arranged parallel to each other and perpendicular to the parallel portions (11a, 11a); A first upper rail tube (13) welded to one end of the group of base tubes (12, 12,...) And arranged in parallel to the parallel portions (11a, 11a); A first lower rail tube (14) welded to the other end of the group of base tubes (12, 12, ...) arranged in parallel to the parallel portions (11a, 11a); One end is welded to both ends of the first upper rail tube 13 and the other end is welded to both ends of the first lower rail tube 14 and arranged perpendicular to the parallel portions 11a and 11a. A-shaped upper tube (15, 15) to form an approximately rectangular shape in cooperation with the N-shaped base tube (12, 12) arranged at both ends of the B-shaped base tube (12, 12, ....); A second lower rail tube (16) welded to a portion at which the N-shaped base tube (12, 12, ...) starts to stand and arranged in parallel with the parallel portions (11a, 11a); The second upper rail tube 17 is welded to the portion of the L-shaped upper tube 15 and 15 which is started to be inverted and arranged in parallel with the parallel portions 11a and 11a.

Here, the two leg pipes 11 and 11 are portions 11a and 11a parallel to the truck driver's seat top plate 20 and portions 11b and 11b inverted at both ends of the parallel portions 11a and 11a. 11b and 11b, and the inverted portions 11b, 11b, 11b and 11b are welded to the connecting rods 11c and 11c at their ends.

Applicant, in the application specification of Application No. 20-2001-034689, filed previously herein, does not integrate the parallel portions 11a, 11a and the inverted portions 11b, 11b as separate portions. And the rear end portions of the inverted portions 11b and 11b are inserted into the parallel portions 11a and 11a to selectively maintain the inserted state by bolts.

However, when the tubes constituting the carrier are arranged in a grid basket shape, separate jigs are sequentially provided for welding the respective joints when welding the joints between the tubes, so that the bottom view welding and the top welding are performed. Should be.

To this end, conventionally, a number of separate jigs were required for the jig for welding the respective connecting parts, and in order to avoid the top welding, an auxiliary worker needed to rotate the connection part fixed to the jig. It was necessary to move left, right, up and down, and back and forth to a position where an operator can weld each said connection part.

Therefore, in the welding operation for making the carrier in the shape of a lattice basket, as described above, the welding worker and the auxiliary worker provide a lot of time and effort, and there is a problem that the productivity is low.

Accordingly, the present invention has been made to solve the above problems, and fixedly arrange the tubes constituting the carrier in a grid basket shape, and at the same time rotates the connections between the tubes fixedly arranged in the grid basket shape with respect to the vertical direction And it aims at providing the set jig which can be rotated about a horizontal direction.
