Tower crane vertical jacking anti-tipping alarm

Abstract

The invention relates to a vertical jacking tip-over prevention alarm of a tower crane. The alarm comprises a measuring ruler, an infrared spotter and an alarm assembly, wherein the alarm assembly comprises a panel; a buzzer, a leveler, an indication pointer and an angular scale below the indication pointer are arranged on the panel; fixing contacts are further mounted on two sides of the indication pointer; the fixing contacts and the buzzer are connected with a battery on the back side of the panel through circuits; a track is mounted on the top of the panel; the measuring ruler is mounted on the track; the infrared spotter is mounted on one side of the measuring ruler. When the alarm is used, information that a tip-over accident can be caused when the perpendicularity is too high and exceeds 0.2% of the standard is provided in time, the 'danger' is prompted to operators in an early warning mode, so that the operation is stopped immediately and the deviation is corrected, and thus the happening of the tip-over accident is prevented; the alarm has the characteristics of simple structure, small size, simplicity in operation, convenience in carrying and the like.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a vertical jacking anti-tipping alarm for a tower crane. Background technique [0002] With the rapid development of the construction industry, tower cranes have become an indispensable means of vertical transportation, and their safe operation has also become an important indicator of safe production in the construction industry. However, in recent years, the frequency of tower crane tipping accidents in various places has shown a linear upward trend. The reason is that operators themselves cannot strictly control the allowable deviation of verticality of 2‰ in accordance with national standards. For tower cranes used in many projects, the verticality needs to be measured by theodolite. However, in fact, most operators only operate by feeling or experience, resulting in the inability to strictly control the deviation. In turn, providing a tool that is easy to ope...
