A method for measuring the verticality of a tower crane using an electronic compass

Abstract

This invention provides a method for measuring the verticality of a tower crane using an electronic compass, comprising the following steps: Step 1: Measurement equipment selection: including a main controller, an electronic compass, a display screen, and an alarm; Step 2: Equipment installation: Install the electronic compass at any main member position on the top of the standard section, install the main controller and display screen in the operator's cab, and install the alarm in a suitable location; Step 3: Verticality measurement: Input the coordinates of the four main members at the foundation position and the tower crane height H into the main controller. The main controller calculates the verticality of the tower crane by reading the coordinates of the electronic compass. If the verticality exceeds the standard, the alarm will sound. This method can effectively detect the verticality of the tower crane in real time. Connecting the main controller to a mobile phone allows for real-time reading of the tower crane's verticality information on the mobile phone. If the verticality exceeds the standard, the mobile phone can also issue an alarm; thus, it can promptly detect abnormalities in the verticality of the tower crane.

Description

Technical Field

[0001] This invention relates to the field of electronic compass tower crane verticality measurement technology, specifically a method for measuring tower crane verticality using an electronic compass. Background Technology

[0002] The verticality of tower cranes is a key aspect of ensuring their safe operation and all safety inspections, highlighting its importance. Currently, tower crane verticality is monitored using a theodolite or total station in conjunction with a measuring tape. The accuracy of this method depends heavily on the instrument's precision and the operator's skill. Monitoring frequency is also limited, typically occurring during safety inspections and maintenance. Relying solely on manual monitoring and pre-tensioning cannot provide real-time monitoring. To better address the challenges of monitoring and providing early warning of tower crane verticality, and to effectively improve the safety and economy of tower crane operation, this invention provides a method for measuring tower crane verticality using an electronic compass. Summary of the Invention

[0003] The purpose of this invention is to provide a method for measuring the verticality of a tower crane using an electronic compass, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for measuring the verticality of a tower crane using an electronic compass, comprising the following steps:

[0005] Step 1: Selection of measuring equipment: including main controller, electronic compass, display screen and alarm;

[0006] Step 2: Equipment installation: Install the electronic compass at any main limb position at the top of the top standard section, install the main controller and display screen in the cab, and install the alarm in a suitable position;

[0007] Step 3: Verticality measurement: Input the coordinates of the four main components of the foundation and the tower crane height H into the main controller. The main controller calculates the verticality of the tower crane by reading the coordinates of the electronic compass. If the verticality exceeds the standard, the alarm will sound.

[0008] Preferably, step 3 specifically involves: the coordinates of the basic position main limbs being (X1, Y1), (X2, Y2), (X3, Y3), and (X4, Y4), respectively, and the main controller reading the coordinates of the electronic compass, which are the coordinates of the top main limb of the uppermost standard section (X', Y').

[0009] Preferably, the verticality of the tower crane boom when it is located on the north side is:

[0010] The verticality of the tower crane boom on the west side is:

[0011] If there is a large deviation in the four verticalities, it indicates that the standard section of the tower has undergone significant torsional deformation.

[0012] Preferably, the equipment in step 1 is installed on a standard section tower crane with a 2m cross-section.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention provides a method for measuring the verticality of tower cranes using an electronic compass. This method effectively detects the verticality of the tower crane in real time. By connecting the main controller to a mobile phone, the verticality information can also be read in real time on the mobile phone. If the verticality exceeds the standard, the mobile phone can also issue an alarm. Timely detection of abnormalities in the verticality of the tower crane greatly improves the safety and economy of tower crane operation. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see the appendix Figure 1-3 This invention provides a method for measuring the verticality of a tower crane using an electronic compass, comprising the following steps:

[0020] Step 1: Selection of measuring equipment: including main controller, electronic compass, display screen and alarm; the main controller, electronic compass, display screen and alarm are installed on a standard section tower crane with a 2m cross-section;

[0021] Step 2: Equipment installation: Install the electronic compass at any main limb position at the top of the top standard section, install the main controller and display screen in the cab, and install the alarm in a suitable position;

[0022] Step 3: Verticality measurement: Input the coordinates of the four main components of the foundation and the tower crane height H into the main controller. The main controller calculates the verticality of the tower crane by reading the coordinates of the electronic compass. If the verticality exceeds the standard, the alarm will sound.

[0023] Specifically: the coordinates of the main limbs at the base position are (X1, Y1), (X2, Y2), (X3, Y3), and (X4, Y4). The main controller reads the coordinates from the electronic compass, which are the coordinates of the top main limb of the uppermost standard section (X', Y'). The verticality of the tower crane jib when it is located on the north side is...

[0024] The verticality of the tower crane boom on the west side is:

[0025] If there is a large deviation in the four verticalities, it indicates that the standard section of the tower has undergone significant torsional deformation.
