Embodiment 1

[0061] The monitoring device for the hoisting condition of the tower material provided in this embodiment is a device for monitoring the in-place height of the tower material and the distance between the tower material and the tower body during the tower material lifting process during the iron tower erection construction. It includes a wireless sensor group 9, an ad hoc wireless local area network 15 for transmitting sensor data, and a monitoring terminal 14 for processing data and displaying monitoring results.

[0062] like figure 1 As shown, the lifting of the tower material refers to binding and fixing one end of the lifting rope 2 to the tower material 1, and the other end is led out of the tower to the traction device 6 through the single-wheel upward tackle 3, the waist tackle 5, and the ground tackle 5, and the traction equipment is used to provide power. The process of lifting the tower material to the predetermined position.

[0063] The pole inclination sensor 4 r...

Embodiment 2

[0071] like Figure 4 As shown, the real-time calculation refers to the use of some sensors to monitor key parameters to obtain the spatial position and attitude of the pole-holding system, and then deduce the distance calculation model between the tower material 1 and the tower body. In the calculation model, all parameters obtained through sensor measurement adopt instantaneous values ​​to realize real-time monitoring of the distance between the tower material 1 and the tower body.

[0072] The calculation model for the distance between the tower material and the tower body shall be determined in the following way:

[0073] ζ——the inclination angle of the pole to the vertical line, (°);

[0074] α——the inclination angle of the hoisting rope to the horizontal plane, (°);

[0075] H——The rise height of the tower material, m;

[0076] h 0 ——The height of the erected tower exposed by the holding pole, m;

[0077] h 1 ——the working height of the pole (the height of the most...

Embodiment 3

[0105] Preferably, the exterior material of the integrated sensor adopts two kinds of contrasting color plastics (such as orange and blue, red and green) that are easy to observe outdoors, so as to facilitate the distinction during use.

Abstract

The invention provides a monitoring device for the tower material hoisting condition and a monitoring method of the monitoring device. The monitoring device is characterized in that the monitoring device comprises a sensor set,a self-built wireless local area network and a monitoring terminal, wherein the sensor set is composed of a wireless integrated sensor and a derrick inclination angle sensor; the wireless integrated sensor is mounted above a hoisting rope hook and used for monitoring the hoisting height of a tower material and the working inclination angle of a hoisting rope at the sametime; the derrick inclination angle sensor is installed on a derrick and used for monitoring the real-time working inclination angle of the derrick; and the monitoring terminal acquires data acquiredby the sensor set through the self-built wireless local area network. The monitoring device and the monitoring method can solve the technical problem that the real-time condition of the tower materialhoisting process cannot be quickly and accurately obtained in existing tower material hoisting process monitoring adopting an empirical method as the main method.

Description

technical field [0001] The invention belongs to the technical field of transmission line iron tower construction, and in particular relates to a monitoring device and a monitoring method for tower material lifting conditions. Background technique [0002] With the rapid development of electric power construction, the voltage level of transmission lines continues to increase, and the construction of iron towers faces more complicated and even dangerous working conditions. Especially when assembling some high-voltage iron towers with taller towers, because the ground command personnel and the operators on the tower are far apart, their hearing and sight distance are limited, and there may be problems between the tower materials and the assembled towers when lifting the tower materials. body collision or even the tower material falling off the ground or the tower material exceeding the height in place. This not only reduces the normal construction efficiency, but also causes e...
