Problems solved by technology
[0002] At present, there is no very suitable mechanism for welding the outer ring seam of the tower. Most of them use a welded four-column style platform. The height of the platform cannot be adjusted, and it is laborious to move. It is not suitable for welding towers of different specifications
Even if some welding platforms can be raised and lowered, the lifting stability is poor, and welders are in danger on the platform

Embodiment Construction
[0018] Combine below Figure 1 to Figure 4 Detailed description of the present invention:
[0019] The gantry-type tower tube circumferential seam welding frame includes a platform 1, four uprights 2, and two bottom beams 3 parallel to each other. The four uprights 2 are arranged between the platform 1 and the bottom beam 3. A lifting platform 4 is arranged inside the four uprights 2, and the lifting platform 4 is connected to a lifting mechanism on the platform 1 through a steel wire 5. The four corners of the lifting platform 4 are provided with a guide wheel group 6 which consists of two guide wheels 7 located on the upper and lower surfaces of the lifting platform 4, and each corner of the lifting platform 4 passes through two sets of guide wheels The group 6 is in contact with the inner end surface of the corresponding column 2, and the two sets of guide wheels 6 respectively contact the two adjacent inner end surfaces of the column 2, and each guide wheel 7 can roll up and...

The invention discloses a gantry-type tower circular seam weld holder comprising a platform, four upright posts and two parallel mudsills, wherein the four upright posts are arranged between the platform and the mudsills; lifting tables are arranged in the four upright posts and are connected with a lifting mechanism on the platform via a steel wire rope; four corners of each lifting table are all provided with pulley sets; each pulley set comprises two pulleys positioned on the upper surface and the lower surface of each lifting table; each corner of the lifting table contacts with the end surface of the inner side of a corresponding upright post by two pulley sets; two pulley sets respectively contact with two adjacent inner end surfaces of the upright post; each pulley can roll up and down along the contacted upright post; and a locking mechanism is arranged between two adjacent pulley sets and is in contact positioning with the upright post by an extension screw. The weld holder has the advantages of novel structure and convenience of use and can effectively improve the working efficiency for welding.
Description
Technical field [0001] The invention relates to a bracket used for welding outer ring welds in the manufacturing process of pressure vessels or towers. Background technique [0002] At present, there is no very suitable mechanism for welding the outer circumferential seam of the tower. Most of them use a welded four-column style platform. The height of the platform cannot be adjusted, and it is laborious to move. It is not suitable for welding towers of different specifications. . Even if some welding platforms can be raised and lowered, the lifting stability is poor, and electric welders are in danger on the platform. Therefore, the design of a special bracket for welding large cylindrical outer rings has positive and progressive significance for improving welding efficiency and improving the working environment of electric welders. Summary of the invention [0003] The purpose of the present invention is to provide a gantry-type tower tube circumferential seam welding frame, w...
