Abstract

The invention discloses a tower crane climbing system. The system involves a tower crane body, wherein the tower crane body is formed by sequentially connecting standard knots in vertical direction, acrawling ladder arranged in vertical direction is arranged on the tower crane body, a lifting mechanism is arranged at the upper end of the tower crane body, a fixing shaft is detachably connected tothe upper end of the tower crane body, the fixing shaft is sleeved with a steel wire rope, one end of the steel wire rope is connected with a counterweight box, the other end of the steel wire rope is connected with a strap rope, the end, close to the strap rope, of the steel wire rope is connected with a hook, a guiding mechanism for guiding the counterweight box to move in the vertical direction is detachably connected to the tower crane body, the guiding mechanism comprises fixing plates fixed on the tower crane body, two fixing plates are arranged at intervals in the vertical direction, aguiding steel wire in a tensioned state is fixedly arranged between the two fixing plates, and the guiding steel wire penetrates through the counterweight box. The system has the effect of keeping the counterweight block used for stable movement.

Description

technical field [0001] The invention relates to the technical field of tower crane auxiliary systems, in particular to a tower crane climbing system. Background technique [0002] Construction tower cranes are the most commonly used lifting equipment on construction sites. Usually, tower crane operators have to climb from the ground to the top of the tower to operate the tower crane. Therefore, this is a high-altitude and dangerous job. Existing tower cranes lack facilities to protect the personal safety of tower crane operators, especially in the process of climbing to the top of the tower, tower crane operators not only consume physical strength, but also have a low safety factor when climbing with bare hands. [0003] The Chinese utility model patent with the authorized announcement number CN203946820U discloses a safety device for building tower cranes, including a climbing ladder, two pulleys, a safety rope, a buckle rope, two safety buckles and a counterweight, and the...
