Technical Field

[0001] The utility model relates to the technical field of anti-kinking of main hoisting wire ropes when replacing a tower crane, in particular to preventing the main hoisting wire ropes of a tower crane from being kinked when being replaced. Background Art

[0002] As the main vertical transportation equipment for construction, tower cranes are widely used in the construction industry. The safe use of tower cranes is crucial in construction sites, and their maintenance is increasingly becoming an important issue that needs to be addressed on construction sites.

[0003] During the use of tower cranes, wire ropes often deform, stab, break, and fracture, which poses a great safety hazard. During replacement, the wire rope is too long and is restricted by the construction site, so the wire rope cannot be effectively unfolded, which will cause the wire rope to be kinked and deformed during the replacement process and cannot be used, causing serious material waste. According to the current situation, it is urgent to develop a tower crane main winch wire rope anti-kink device to avoid damage to the wire rope during the replacement process, thereby reducing material costs, improving operating efficiency and reducing the labor intensity of operators. Summary of the invention

[0004] Technical issues to be solved

[0005] The technical problem to be solved by the utility model is: when a construction unit needs to replace the main hoisting wire rope of a tower crane, the wire rope cannot be effectively unfolded due to limited construction site. The anti-winding device can be used to quickly solve the problem of limited site, avoid damage caused by the inability to effectively unfold the wire rope, thereby saving maintenance time, reducing material costs, reducing safety hazards during operation, improving operation production efficiency and reducing the labor intensity of operators.

[0006] In order to solve the above technical problems, the utility model provides a tower crane main hoist wire rope anti-kink device, characterized in that it includes: a cross bar, an upper fixed tray, a lower fixed tray, a vertical pole, and a bolt; the cross bar is provided with a φ10mm round hole at one end, and is installed on the upper part of the upper fixed tray by bolts for placing the wire rope; the upper fixed tray is made of welded steel plates, and is provided with an ear plate for installing the cross bar and the vertical pole at the upper part, and a bearing groove is provided at the center position of the lower part to install a built-in bearing, and the inner ring of the built-in bearing is installed on the shaft on one side of the lower fixed tray, which can be rotated 360° to play a rope breaking role; the lower fixed tray is made of welded steel plates, and a φ40mm shaft is welded at the center of the upper surface, and is connected to the upper fixed tray by a bearing; the vertical pole is welded by a rectangular tube and a steel plate, and is hinged with the upper fixed tray, and cooperates with the cross bar to prevent the wire rope from falling off and tangling during rotation; the bolt is M10-60, and is used to hinge and fix the cross bar and the vertical pole.

[0007] Preferably, the cross bar is made of a 40mm×20mm×3mm rectangular tube, and the material is Q235B.

[0008] Preferably, the upper fixed tray is made of a φ300mm, 8mm thick steel plate, and the material is Q235B.

[0009] Preferably, the lower fixed tray is made of φ500mm×8mm steel plate, welded with a φ40mm, 150mm long shaft, and the material is Q235B.

[0010] Preferably, the vertical pole is welded by a 300mm×20mm×3mm rectangular tube and a 38mm×30mm×6mm ear plate, and a φ10mm round hole is provided on the ear plate, which is connected to the upper fixed tray by bolts.

[0011] Preferably, the bolts are M10-60 common hexagonal bolts, which are used to connect the upper fixed tray with the crossbars and vertical bars.

[0012] (III) Beneficial effects

[0013] An anti-kink device for the main hoisting wire rope of a tower crane can quickly break the tension of the wire rope, avoiding problems such as kinking and cage-shaped distortion of the wire rope caused by the inability to effectively unfold the wire rope due to the small construction site of the construction unit. It not only reduces the labor intensity of operators, but also saves material cost consumption, while saving working time and improving operation production efficiency, with good economic and social benefits.
