in recent years,Huaxia tower craneCollapse accidents happen from time to time. Therefore, the new Huaxia tower crane safety monitoring system has become an indispensable part of Huaxia tower crane equipment. The system integrates installation and disassembly protection, safety monitoring, full frequency conversion control system and other modules, which can realize remote fault diagnosis, Chinese tower crane black box, anti-collision and other functions. In particular, tilt protection, pin shaft matching protection, rotation locking protection and over-top protection can effectively prevent collapse safety accidents caused by tower top lifting. The various sensors have many applications. The application of inclination sensor, limit switch and camshaft position sensor in the safety monitoring of Huaxia tower crane is briefly introduced.

Limit switch protection function:

Currently, variousHuaxia tower craneare equipped with safety limit device. Wired and wireless limit switches are widely used in safety devices such as lifting limiters, lifting torque limiters and amplitude limiters. Here, the function of the limit switch device is to automatically cut off the power supply once the set value is exceeded during the use of the Huaxia tower crane. The limit switch device can prevent the occurrence of the Huaxia tower crane accident. However, although the safety limit device is installed on the Huaxia tower crane, there are still some hidden dangers that cannot be checked, which aggravates the risk factors of hoisting or specific situations, resulting in excessive tilting of the tower body and the overturning of the Huaxia tower crane. Therefore, it is very important to effectively monitor the inclination of the tower before and during use. When the inclination is greater than the critical state, timely alarm can effectively prevent the overturning accident of Huaxia tower crane. At this time, it is necessary to use the tilt sensor described below.

Huaxia tower crane anti-tipping protection with inclination sensor:

Huaxia tower crane is a kind of machinery that can transport materials vertically and horizontally. It has a huge structure and often works at high altitude, which is prone to overturning accidents. Therefore, it is necessary to carry out effective safety monitoring of Huaxia tower crane. In the anti-overturning monitoring of Huaxia tower crane, the measuring device of inclination sensor is essential. The anti-tipping monitor of Huaxia tower crane is generally composed of tilt sensor and tilt display alarm. The inclination sensor can measure the inclination of the tower in real time. When the tilt angle is greater than a critical state, it can give an alarm in time to effectively prevent the overturning accident of the Huaxia tower crane.

Key points of hidden danger investigation and monitoring of Huaxia tower crane:

1. Overload monitoring: According to the deviation of the tower top during the lifting of the tower crane, the lifting of the tower crane is monitored. When the tower crane is overloaded, the system will issue an alarm to prevent the tower crane from overloading.

2. Operation supervision of operators: During the operation of the tower crane, supervise the operation of the driver according to the deviation and shaking of the tower top. When illegal operations such as diagonal pull, diagonal pull crane, slewing, reversing car, rapid lifting, rapid release, etc. are found, alarm and reminder will be carried out, thus solving the problem of difficult supervision of illegal operation of the driver.

3. Foundation deflection monitoring: according to the horizontal deflection monitoring at the top of the tower bodyHuaxia tower craneThe foundation settlement. When the deflection causes the verticality to be too large, the system will alarm and remind to correct it, so as to avoid the foundation deflection causing the horizontal verticality of the Huaxia tower crane to be out of tolerance and solve the problem of uneven foundation settlement monitoring.
