Anti-drifting anti-rotating structure for main chord member of tower body

Abstract

The invention discloses an anti-drifting anti-rotating structure for a main chord member of a tower body, and relates to the related technical field of building machinery. The anti-drifting anti-rotating structure for the main chord member of the tower body comprises an anti-drifting anti-rotating mechanism, a first fixing mechanism, a second fixing mechanism and a tower body main chord member mechanism, wherein the anti-drifting anti-rotating mechanism is sleeved with one end of the first fixing mechanism, the first fixing mechanism is connected with the interior of the tower body main chord member mechanism in an inserted mode, the second fixing mechanism is arranged below the first fixing mechanism, and is connected with the interior of the tower body main chord member mechanism in an inserted mode, the second fixing mechanism is arranged below the first fixing mechanism, the second fixing mechanism is connected with the interior of the tower body main chord member mechanism in an inserted mode, and one end of the second fixing mechanism is sleeved with the anti-drifting anti-rotating mechanism. According to the anti-drifting anti-rotating structure for the main chord member of the tower body, through the anti-drifting anti-rotating mechanism, the first fixing mechanism, the second fixing mechanism and the tower body main chord member mechanism, the problems that according to existing pin shafts, the maintenance cost is improved, and impact vibration, alternating loads and shaft hole abrasion deformation are caused during working are solved.

Description

technical field [0001] The invention belongs to the related technical field of construction machinery, and in particular relates to an anti-channeling and anti-rotation structure for main chords of a tower body. Background technique [0002] At present, the main chord mechanism of the tower crane tower body is generally connected by pin shafts. After the pin shafts are driven into the connection holes, the pin shafts are fixed by safety pins and cotter pins to effectively prevent the pin shafts from being impacted and vibrated during use. As a result, the pin shaft escapes from the connecting hole, causing a tower crane safety accident. The existing installation method effectively restricts the axial movement of the pin shaft, so that the pin shaft cannot escape from the shaft hole due to axial movement, ensuring the safe use of the tower crane. However, in the actual use of the main chord connecting pin shaft, in addition to the impact vibration, it is also affected by the ...
