Background
At present, a high large formwork supporting system is used in building construction, belongs to a high accident occurrence point, a group death and group injury event can occur once the supporting system is unstable, the stability of the supporting system is directly determined by the fastening degree of a nut of a steel pipe fastener, namely, the fastener fails due to the sliding of the nut, and finally the support collapses.
The standard section bolt of tower crane is not hard up very easily among the construction, and whether current tower crane nut is not hard up detects still adopts the most original method, and the manual work is regularly climbed a tower crane nut and is step up to avoid because the not hard up harm that produces of nut. However, in the mode, each nut of the tower crane needs to be tightened by workers, pertinence is unavailable, a large amount of time is consumed, and meanwhile, the workers are risky to climb for a long time. And still appear after the manual inspection because the nut becomes flexible and lead to the tower crane collapse incident frequently, and also lack corresponding early warning solution among the prior art.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the tower crane nut looseness monitor based on magnetic induction, wherein equipment is arranged on a tower crane nut, and can be driven to move when the tower crane nut rotates anticlockwise, so that the equipment can detect corresponding displacement, and early warning is given.
The technical scheme adopted by the utility model is as follows: the utility model relates to a tower crane nut loosening monitor based on magnetic induction, which comprises a smart nut and an induction magnet, wherein the smart nut is buckled on one surface of a tower crane nut through a portable fastener, the induction magnet is adsorbed on a member of a tower crane and used as a positioning coordinate, and when the tower crane nut rotates, the smart nut sends a signal when detecting that the tower crane nut rotates anticlockwise (the tower crane nut is in a loosening state).
Further, wisdom nut includes control panel and alarm lamp, the control panel adopts STM32 chip L series's low-power consumption chip as the main control core of equipment to insert three full polarity hall sensor, two full polarity hall sensor is used for judging displacement direction and amplitude, another full polarity hall sensor resets as trigger equipment, just the alarm lamp of a hi-lite is connected to the control panel is used as the early warning.
Further, the alarm lamp is detected at the wisdom nut bright red light when the tower crane nut takes place anticlockwise rotation to the scintillation is reported to the police.
Adopt above-mentioned structure this scheme a tower crane nut based on magnetic induction not hard up monitor, the beneficial effect who gains as follows:
(1) the construction safety of the tower crane can be improved;
(2) the loosening condition of the nut can be monitored in real time, and the hysteresis of manual inspection is solved;
(3) the method can improve economic benefits, solves the problem that the original manual inspection needs shutdown and matched inspection, and can tighten the loose nut after work.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figures 1-3, the tower crane nut looseness monitor based on magnetic induction comprises a smart nut 1 and an induction magnet 2, wherein the smart nut 1 is buckled on one surface of a tower crane nut 3 through a portable fastener 4, the induction magnet 2 is adsorbed on a member of a tower crane to serve as a positioning coordinate, and when the tower crane nut 3 rotates, the smart nut 1 sends a signal when detecting that the tower crane nut 3 rotates anticlockwise.
Wherein, wisdom nut 1 includes control panel and alarm lamp, the control panel adopts STM32 chip L series's low-power consumption chip as the main control core of equipment to insert three full polarity hall sensor, two full polarity hall sensor is used for judging displacement direction and amplitude, another full polarity hall sensor resets as trigger equipment, just the alarm lamp that a hi-lite is connected to the control panel is used as the early warning.
The alarm lamp is detected at wisdom nut 1 bright red light when tower crane nut 3 takes place anticlockwise rotation to the scintillation is reported to the police.
The working principle is as follows: as shown in fig. 2, the proximity of the induction magnet 2 is in state 1, the default states IC2(Left) and IC1(Right) are both 1, and the nut direction: (looking at the sensor magnet at the lower end), the working distance of the all-polarity hall sensor is idle output high level, and the induction magnet 2 is close to low level.
Counterclockwise-upward shift 11 → 10 → 00 → 01 → 11 round
Clockwise-shift down 11 → 01 → 00 → 10 → 11 round
Three groups of full-polarity Hall sensors inside the intelligent nut 1 detect when the tower crane nut 3 rotates anticlockwise, the alarm lamp lights a red light, and the alarm lamp flashes to give an alarm and sends a signal.
