Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, it is a tower crane tower top inclination diagnosis device of the present invention, which is installed on a main limb 2 of the tower crane slewing tower body.

[0016] The device for diagnosing the inclination angle at the top of the tower crane body includes a hoop 1 , a pair of fixed columns 3 , an inclination sensor 4 , and a display record alarm device 7 .

[0017] The hoop 1 is used to hoop the main limb 2 . It includes a V-shaped middle section that hoops the adjacent two sides of the main limb 2, and a left edge section and a right edge section connected with the V-shaped middle section. Threaded holes are provided on the left and right edge segments.

[0018] In the embodiment of the present invention, a pair of fixing posts 3 are long screw rods, which respectively pass through the threaded holes on the lef...

Abstract

The invention provides a tower body top inclination diagnosis device for a tower crane and a diagnosis method of the tower body top inclination diagnosis device. The device comprises a hold hoop for holding a slewing tower limb of a tower crane, a pair of fixing columns, an inclination sensor and a display recording alarm device, wherein the fixing columns are connected with two ends of the hold hoop, the inclination sensor is connected with the other ends of the fixing columns, and the display recording alarm device is electrically connected with the inclination sensor which is provided with a clamping port for clamping the slewing tower limb of the tower crane. The inclination sensor is mainly used for measuring the tower body top inclination, and is clamped on the slewing tower limb of the tower crane through the clamping port and connected with the hold hoop through the fixing columns; and the display recording alarm device 7 makes a sound-light alarm, controls a hoisting circuit and simultaneously records overload information when serious overload occurs.

Description

technical field [0001] The invention relates to a method and device for judging overload of a tower crane (abbreviated as tower crane), in particular to a method and a device for judging tower crane overload based on an established characteristic model of inclination angle at the top of the tower body when the tower crane is in good condition. Background technique [0002] With the prosperity and development of real estate in recent years, due to its unique advantages, such as wide working range, high lifting height and large hoisting load, the application of tower cranes is increasing. [0003] The tower crane belongs to the high-altitude operation device. Whether it is in the working state or the non-working state, the safety of the tower crane can only be ensured if the torque on the tower body is within its bearing range. But in fact, at present, most tower cranes have a lot of illegal operations during their work. The most typical illegal operation is excessive lifting...
