Description

Technical Field

[0001] The utility model relates to the field of crane installation structures, in particular to an auxiliary installation tool for a bolt tensioner. Background Art

[0002] During the installation of floating cranes, the installation of slewing bearings is a heavy-duty process that determines the overall progress of the work. With the increase in the number of products, the traditional purely manual installation method can no longer meet the requirements of rapid advancement of the process. In addition, manual operations are more restricted in the narrow space of the inner platform of the cylinder, and it is also difficult to move the bolt tensioner. At the same time, because the bolt tensioner needs to be kept in a balanced state, at least two workers are required to lift the work, and one worker operates the tensioner alone, so the labor demand is relatively large. For the installation of some projects, some simple tooling has also been derived. The main functional advantage is that it can easily lift the bolt tensioner, eliminating the unstable factors of manual lifting. However, this type of tooling product has a single function and is only suitable for simple lifting work. Due to volume limitations, it is impossible to enter the internal work, and it is heavy. Utility Model Content

The opening directions of the top limit slot and the middle and lower limit slot are consistent, so the bottom of the bolt tensioner passes through the top limit slot and the middle and lower limit slot in sequence and is placed on the bottom plate.

[0013] Furthermore, an arc-shaped plate is installed on the inner wall of the top limit slot;

[0014] The middle and lower limiting part includes a supporting column and a limiting folding plate, the supporting column is fixed on both sides of the bottom plate, the limiting folding plate is a horizontally arranged symmetrical structure, including a first transverse section, a first longitudinal section, a first inclined section, a second transverse section, a second inclined section, a second longitudinal section and a third transverse section arranged in sequence, and the first and third transverse sections are connected to the supporting column, and the first longitudinal section, the first inclined section, the second transverse section, the second inclined section and the second longitudinal section constitute the middle and lower limiting groove.

[0019] 3) The overall size of the utility model can meet the smooth movement of the platform inside the cylinder, and is suitable for narrow spaces and complex terrains inside the cylinder. It has a high pass rate and is easy to operate. One person can perform the operations of transportation, locking and lifting. The internal space structure of this structure allows construction workers to use ratchet wrenches at a large angle, overcoming the problem that the bolt tensioner cannot be conveniently used and transported under limited space;

[0020] 4) The operation of the lifting system of the utility model does not overlap with the space used by the bolt tensioner, thus avoiding waiting waste between processes. BRIEF DESCRIPTION OF THE DRAWINGS
