Problems solved by technology

[0004] It can be seen from Figure 1 that in order to solve this problem, most of the existing technologies use encoders to measure the rotation angle of the tower crane. The encoder is installed on the shaft driven by the motor 2 at this rotation angle, and the original mechanical structure must be disassembled during installation.

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] It can be seen from Fig. 2 that the present invention includes: the boom 10 of the tower crane; also includes: a geomagnetic sensor 11; the geomagnetic sensor 11 is fixedly placed on the balance arm of the boom 10;

[0016] Can also comprise a junction box that can play waterproof, put corrosion effect outside geomagnetic sensor 11;

[0017] A support 12 is fixed on the balance arm of the boom 10, and the geomagnetic sensor 11 is fixedly arranged on the upper end of the support 12;

[0018] The bracket 12 is fixed in the guardrail 13 of the balance arm.

[0019] The invention can measure the rotation angle of the tower crane and record the running conditions of the rotation angle, so that the operator of the tower crane can know the rotation angle value of the tower crane in time, and can lock the over-angle rotation operation of the tow...

Abstract

The present invention relates to one kind of tower crane with geomagnetic sensor. The tower crane includes one giant arm, and one geomagnetic sensor fixed onto the balance arm of the giant arm. The present invention has the positive effects of simple installation, and relatively high precision and resolution.

Description

technical field [0001] The invention relates to a tower crane, in particular to a tower crane with a structure for measuring the turning angle. Background technique [0002] With the rapid development of my country's social economy and the emergence of a large number of high-rise buildings, the safety and timely maintenance of elevators are becoming more and more important, which also puts forward higher requirements for tower cranes. [0003] Most of the current tower crane systems do not have human-computer interaction monitoring equipment, and most professional operators of tower cranes operate tower crane systems based on their own experience and feelings. As the national construction agency has attached great importance to the tower crane system in the past one or two years, it will be mandatory to install the tower crane monitoring system in the next few years: including the measurement of the rotation angle. [0004] It can be seen from Figure 1 that in order to solv...
