The technical solution used in the present invention is as follows:
A kind of building hanging basket safety guard; comprise hanging basket and two bogeys; one group of pivot pin is set respectively in each bogey to link to each other with hanging basket; it is characterized in that: be respectively equipped with one group of foil gauge in each pivot pin and consist of a shaft pin sensor; one group of foil gauge in the shaft pin sensor connects into resistance bridge, and its output connects respectively amplification modulate circuit, A/D change-over circuit, microprocessor and a display by successively connection and forms electronic-controlled installation.
On the basis of technique scheme, following further technical scheme can be arranged:
The face of cylinder of shaft pin sensor is provided with the twice groove, and the foil gauge of two symmetries is set respectively in the per pass groove, and shaft pin sensor inside is provided with fairlead, and each foil gauge connected wire is connected to electronic-controlled installation by fairlead respectively;
The microprocessor control end is connected with respectively clock circuit, memory, EPROM and keyboard;
The microprocessor control end is connecting communication interface circuit, printout interface circuit respectively;
The microprocessor control end also links to each other with photoelectric isolating circuit and braking holding circuit.
The invention provides a kind of detection principle and method of building hanging basket safety guard, the building hanging basket protective device is comprised of the two large divisions, i.e. sensor and control display device.Sensor adopts the pivot pin form structure.After building hanging basket installs, the weight of building hanging basket is transferred on the shaft pin sensor that is installed in bogey, make shaft pin sensor produce the voltage change of trace, this shaft pin sensor output voltage is transformed into data signal after instrument amplifier amplifies and by high-resolution A/D converter, data signal is directly read and is processed by chip microprocessor, is converted into after treatment gravimetric value.The rated value of this weight signal and setting compares, when hoisting weight reach specified hoisting weight 90% the time, first via alarm relay 1 work, alarm begins to report to the police, first via alarm lamp is bright, shows simultaneously weight weight; When hoisting weight reach specified hoisting weight 100% the time, the No. the second alarm 2 is started working, the second road alarm lamp is bright, when the weight of hanging basket for surpass or be lower than setting weight 30% the time, 3 work of Third Road alarm at this moment, are cut off the power supply of building hanging basket automatically.This controller also can set up on their own by gravimetric value as required.
Beneficial effect of the present invention:
The building hanging basket safety guard makes this device have extremely strong antijamming capability can be applicable to the control display of various building hanging baskets owing to having adopted shaft pin sensor to carry out the detection of signal and having adopted advanced anti-interference device and original Software for Design.The use of this device can be guaranteed the use safety of building hanging basket, and the generation that reduces even stop accident provides huge economic benefit and social benefit for production unit and the applying unit of building hanging basket.

Implementation
As shown in Figure 3, building hanging basket 9 two ends link to each other with a pair of bogey 11, are respectively equipped with two each and every one shaft pin sensors 1 in each bogey 11 and link to each other with building hanging basket 9, and bogey moves up and down along pole-climbing 10.
As Fig. 2, shown in Figure 3 be shaft pin sensor 1, replace pivot pin with shaft pin sensor among the present invention, because building hanging basket has two bogeys, so need with four shaft pin sensors, therefore, when hanging basket carrying weight, weight just is added on the sensor, makes sensor that voltage signal output be arranged.
The face of cylinder of shaft pin sensor 1 is provided with twice groove 5, the resistance strain gage 2 of a symmetry is set respectively in the per pass groove, shaft pin sensor 1 inside is provided with radial lead hole 6 and axial lead hole 7, and each resistance strain gage 2 connected wire 8 is connected to electronic-controlled installation by fairlead respectively.
As shown in Figure 4,1 one group of foil gauge 2 connects into resistance bridge in the shaft pin sensor, this shaft pin sensor operating principle is, four resistance strain gages are sticked on the pivot pin elastic body, and composition is such as the resistance bridge of Fig. 4, when elastic body is subject to making the time spent elastic body and will deforming of power, and the resistance of resistance strain gage is changed, according to electric bridge and poor characteristic, when the two ends of electric bridge add voltage, in addition two ends just have one to be proportional to the signal of telecommunication output that power changes, by detecting the just size of power or weight as can be known of this signal of telecommunication.
