Description
Technical field
The utility model relates to electronic information control application, particularly a kind of attachment type raise scaffold safety guard.
Technical background
Attachment type raise scaffold is the outer scaffold of high-building construction, can carry out lift work, promotes one deck from bottom to up, the layer main body of constructing.When main body construction finishes, fitting up one deck one deck that just descends from top to bottom, until the bottom finishing is finished.Because attaching scaffold has good economic and social benefit, now is extensive use of by high-building construction.Mainly containing of using at present guide tracked, main cover posture, overhanging type, hang pull-type etc. several.Characteristics such as multi-functional, high effect that attachment type raise scaffold has, highly versatile, bearing capacity are big.But attaching scaffold in use, and when attaching scaffold lifting and conveying articles, if scaffold lifting imbalance promptly is not an integral elevating, or the goods that loads surpasses the scope of scaffold carrying, will cause the damage of scaffold and cave in.In order to address the above problem, must safety locking motion be set to attaching scaffold, modal safety locking motion is by being series at mechanical type load transducer, the relay station on the electric block seat in the plane and detecting display instrument automatically and form, per 4 sensor parallel connections are one group and are connected in parallel to relay station, each relay station is connected serially to autoamtic display device with the cable of 1 power line and holding wire unification, and the load of each seat in the plane is limited in the scope of 10 ~ 40kN.When the seat in the plane load exceeded above-mentioned scope, sensor detected display instrument automatically to central authorities immediately and sends alarm signal and indicate unusual seat in the plane and the situation type, cut off that general supply is concurrently spoken, visual alarm.This technical scheme exists obvious defects, is exactly that complex structure, reliability are lower.
The utility model content
The purpose of this utility model is exactly the lower defective of complex structure, reliability that exists in the prior art in order to solve, a kind of attaching scaffold safety guard that provides.
To achieve these goals, the utility model has adopted following technical scheme:
The attachment type raise scaffold safety guard, comprise guide rail, off-load tripod and promote the attachment type raise scaffold that base is formed, it is characterized in that connecting on the off-load tripod upper connecting rod, the upper connecting rod lower end connects a pulling force sensor, the lower end of pulling force sensor connects a lower connecting rod, the lower connecting rod lower end connects electric block, and the electric block lower end connects loop chain, and the loop chain lower end links to each other with the lifting base; The output of pulling force sensor also connects an electronic surveying control device.
Described electronic surveying control device is made up of the amplification modulate circuit, A/D change-over circuit, microprocessor and the display that connect successively, and the microprocessor control end also links to each other with photoelectric isolating circuit and braking holding circuit.
Technique scheme is made up of the two large divisions, i.e. sensor and electronic-controlled installation.Described sensor adopts the resistance-strain type structure, in this structure four strain ga(u)ges are sticked on the elastic body, and composition resistance bridge, when elastic body is subjected 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 with the difference 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.
When the weight of attaching scaffold hoist is transferred on the sensor that is installed on the electric block, make sensor produce the voltage change of trace, this voltage becomes data signal after instrument amplifier amplifies and by high-resolution A/D converter, data signal is directly read by chip microprocessor, is converted into gravimetric value after treatment.The rated value of this weight signal and setting compares, when hoisting weight reach specified hoisting weight 90% the time, first via alarm relay work makes alarm begin to report to the police, first via alarm lamp is bright, shows weight weight simultaneously; When hoisting weight reach specified hoisting weight 100% the time, No. the second alarm is started working, the second road alarm lamp is bright, at this moment, braking protection controller cuts off the power supply of electric block contactless for hoisting automatically, shows weight weight simultaneously; The weight rated value can set up on their own as required in addition.
Advantage of the present utility model is: the attaching scaffold safety guard owing to adopted sensor to carry out the detection of signal and adopted advanced anti-interference device and the design of original software; make the utility model simple in structure, have extremely strong antijamming capability and can be applicable to that the control of various attaching scaffolds shows.The use of this device can be guaranteed the safe in utilization of scaffold, reduces even stop the generation of accident, gives and uses the unit of attaching scaffold that huge economic benefit and social benefit is provided.
