Problems solved by technology

In most cases, the balance is judged by experience, such as observing the bolt connection, the support of each roller of the sleeve frame 20' and the standard section 10', etc., which requires the operator to have considerable practical experience and clear thinking , however, this kind of subjective assumption often leads to wrong results, which is also the main reason why cranes often have accidents in disassembly and assembly conditions.

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] The invention provides a balance detection system of a tower crane.

[0030] Such as Figure 2 to Figure 5 As shown, according to the balance detection system of the tower crane of the present invention, the tower crane includes the lower support 30 and the sleeve frame 20, the balance detection system includes a load cell 80, and the lower support 30 and the sleeve frame 20 pass through the load cell 80 connected.

[0031] The load cell 80 is used as the connecting portion between the lower support 30 and the sleeve frame 20, and detects the force condition of the sleeve frame 20 through its own force, thereby judging whether the upper turning part of the tower crane has reached the The balanced state reduces the occurrence of major personal injury accidents under disassembly and assembly conditions, and improves the safety...

Abstract

The invention provides a tower crane and a balance detection system thereof. In the balance detection system of the tower crane according to the invention, the tower crane comprises a lower support and a stock, the balance detection system of the tower crane comprises a force sensor, and the lower support and the stock are connected through the force sensor. The tower crane according to the invention comprises the balance detection system of the tower crane. Because the stress condition of the stock is detected by the force sensor, whether a rotating part on the tower crane under a dismounting working condition is in a balance state is judged, thereby reducing significant personal injury accidents under the dismounting working condition, and improving the use safety performance of the tower crane.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, and more specifically, to a tower crane and a balance detection system thereof. Background technique [0002] Tower cranes are one of the main construction machines for modern industrial and civil buildings. The performance advantages of tower cranes in terms of lifting height and working range make them widely used in high-rise building construction. [0003] Due to the characteristics of high-altitude operation of tower cranes, there are many factors that induce unsafety. During the installation, use and dismantling of high-rise tower cranes, the level of safety technology management and operators is extremely high, and a little carelessness can easily cause serious accidents. Judging from the accident cases of tower cranes in my country in recent years, the accidents mainly occurred during the assembly and disassembly of tower cranes. As far as the current technical level of to...
