Embodiment Construction

[0016] Such as image 3 As shown: the tilt sensor 2 is a tilt trigger circuit switch, which is mainly composed of a disc-shaped conductor plumb 4 and a cylindrical conductor inner cylinder 5 with a closed bottom. The outer diameter of the conductor plumb 4 is smaller than the inner diameter of the conductor inner cylinder 5. When When the inclination sensor is in a vertical state, the conductor plumb 4 has no contact with the conductor inner cylinder 5, the trigger switch is in an open circuit state, and the alarm does not work; when the inclination sensor is tilted in any direction, the conductor plumb 4 is in contact with the conductor inner cylinder 5 , the trigger switch is in the access state, and the alarm works.

[0017] image 3 The middle inclination sensor is provided with an outer cylinder 6 of an insulator, which plays an insulating and protective role on the conductor inner cylinder 5 . The conductor inner cylinder 5 is provided with a top cover 14, the top cove...

Abstract

The invention relates to a safety monitoring system of tower crane, particularly to an inclination alarming device of tower crane, and belongs to mechanical and electrical equipment processing technology field. The device comprises: a closed loop formed by the electrically connection of a power supply, an inclination sensor, and a sound and light alarm, wherein the inclination sensor is vertically fixed at the part of the tower crane which needs to be monitored; the inclination sensor is an inclination triggering circuit switch, which consists of a disc-shaped conductor plumb and a cylindrical conductor internal barrel; the bottom of the conductor internal barrel is sealed and the top of the conductor internal barrel has a top cover; the top cover is connected with an insulator external barrel through cup screw threads; and the conductor plumb is hanged on the top cover through a plumb hanging string. When the inclination sensor is in a vertical state, the conductor plumb does not contact with the conductor internal barrel, the triggering switch is in off state and the alarm does not work; while the inclination sensor is inclined in any direction, the conductor plumb contacts with the conductor internal barrel, the triggering switch is in on state and the alarm works.

Description

technical field [0001] The invention relates to a tower crane safety monitoring system, in particular to a tower crane tilt alarm device, which belongs to the technical field of electromechanical equipment processing. Background technique [0002] Tower crane is currently the most widely used vertical transportation tool in my country's construction industry. At the same time, tower crane is a kind of special mechanical equipment with high risk. Although the country has issued strict safety regulations and industry standards from the design, manufacture, installation and use of tower cranes, safety accidents of tower cranes still occur from time to time, especially the overall overturning accident of tower cranes will cause huge casualties. loss of life and property. According to relevant statistics, the overall overturning accidents of tower cranes in my country account for more than half of the total number of tower crane accidents. The main reason for this situation is ...
