Problems solved by technology
[0003] At present, there is no special equipment for the tailor welding of the tower top group frame of the tower crane. The conventional tower top welding method is to connect one end with the upper support, and the other end needs to be welded through the shaft, and it is difficult to ensure the accuracy. If the post-welding processing is too expensive High, heavy workload, high labor intensity, high cost
Tower top group frame tooling is not common in the tower crane industry, and welding is generally carried out by matching welding, which is inefficient, time-consuming and labor-intensive

The invention discloses a tower top frame assembly tool for a tower crane. The tool comprises a bottom frame, a backup plate, bearing bases, a positioning base I, a positioning base II and positioning bases III. The pairs of bearing bases used for fixing the top of a bearing tower and the positioning base I are fixed to the bottom frame. Containing grooves are formed in the bearing bases. A positioning hole is formed in the positioning base I and matched with a hole in a chord member on the tower top, and the positioning hole and the hole in the chord member on the tower top are connected through a pin shaft. The end, arranged on the bottom frame, of the backup plate is connected with the connecting end of the tower top, and the positioning bases III connected with a lug plate on the tower top are arranged at the four corners of the backup plate. The positioning base II is arranged at the other end of the bottom frame, and the positioning base II is provided with a positioning hole which is matched with a hole in a pulley shaft of a tower head. The tool is of an integrated type, the two ends of the tool are connected with the lug plate and the pulley shaft in a positioning manner respectively, the middle of the tool supports a whole product piece through the bearing base, and it is guaranteed that when the product piece is placed on the upper side, hole position butt joint can be achieved; and meanwhile, deformation caused by the dead weight is prevented, tower top frame assembly welding is facilitated, tower top welding cost is saved, and labor intensity is reduced.
Description
technical field [0001] The invention relates to a tower crane assembly tool, in particular to a tower top frame assembly tool for the tower crane. Background technique [0002] Tower cranes are referred to as tower cranes for short, also known as tower cranes. The slewing crane with the boom installed on the top of the high tower has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, the boom and the base, etc. The working mechanism has four parts: lifting, luffing, slewing and walking. [0003] At present, there is no special equipment for the tailor welding of the tower top group frame of the tower crane. The conventional tower top welding method is to connect one end with the upper support, and the other end needs to be welded throug...
