Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] figure 1 It is a relationship diagram of the state parameters of the tower crane calculated in the prior art and the actual values ​​of the state parameters of the tower crane. Since the calculation methods of the amplitude, height and rotation limiter are basically similar, here only the calculation of the amplitude limiter is used as an example for illustration. In the prior art, the amplitude limiter (sensor) is calculated through the following steps:

[0020] First, run the luffing trolley of the tower crane to the root of the jib of the tower crane, obtain the sampling value of the amplitude limiter AD1, and the actual amplitude value R1, for examp...

Abstract

The present invention provides a tower crane state parameter measurement method, equipment, system and construction machinery, the method comprising: receiving the sampling value of the tower crane limiter and the tower crane state information, wherein the tower crane state information includes gear position information and time information; according to the sampled value and tower crane status information, calculate tower crane status parameters. The present invention can calculate tower crane state parameter (such as tower crane amplitude value, height value, and slew value) accurately in real time, thereby avoiding the large error between the calculated tower crane state parameter and the actual value. resulting in safety accidents.

Description

technical field [0001] The invention relates to construction machinery, in particular to a method for measuring tower crane state parameters, a tower crane state parameter measurement device, a tower crane state parameter measurement system, and construction machinery. Background technique [0002] Tower cranes, as lifting and transportation machinery widely used on construction sites, are responsible for high-altitude and long-distance transportation. Due to the tower height of the tower crane, the length of the boom, and the large lifting load, the risk factor is very high during use. Once the weight of the tower crane exceeds the rated load, safety accidents such as tipping, arm folding, and waist breaking may occur. Therefore, a tower crane safety monitoring system is installed on the tower crane. The monitoring system uses the amplitude, height and slewing limiters to measure the amplitude, height and slewing in real time, which are important for the safe operation of ...
