Description

A kind of method of test belt force
Technical field
The present invention relates to a kind of pull force calculation instrument, and in particular to a kind of belt force detector and its detection method.
Background technology
During high-rise working including including electric line livewire work, the safety problem of operating personnel is most to be worth The key problem that must pay attention to.Wherein, protect the security tool of high-rise working personnel --- it is crucial that whether seat belt is sufficiently tight. It is all in 2 meters of height of fall datum level and the above, be possible to the operation that eminence is carried out fallen, referred to as high-rise working.According to《Electricity Power safety work order(Power line portion)》The regulation of GB26859-2011, high-rise working should use of seat belts.In order to ensure Every high-rise working personnel's personal safety, before seat belt use, first should visually inspect to seat belt outward appearance, and scene Impact test is carried out, whether seat belt is checked in serviceable condition, if can bear enough loads.In traditional safety In band impact test, operating personnel is often lack of standardization because of operational motion, or performs a task perfunctorily because safety consciousness is not strong, due to not having There is quantizating index to be used as to judge that done impact test is possible to be not reaching to expected standard, so as to leave potential safety hazard.At present, Home and abroad there is no the equipment application for solving this present situation.
Traditional seat belt impact test, mainly is carried out pulling to complete to seat belt by operating personnel, its operating procedure It is as follows:Operating personnel correctly dresses seat belt, by the enclosing belt of seat belt(Its fastener end)Bypass tower material of iron tower or concrete rod body Appropriate location;Safe provided with fastener is fixedly secured on the clasp of seat belt;Operating personnel stands into bow step, firmly backward, Pull three times and more than;Pulling process is experienced by operating personnel, judges that seat belt is qualified, then terminate impact test;To dual fail-safe The impact test method of the standby safety rope of seat belt is ibid.
Which be can be seen that from above-mentioned traditional seat belt impact test step to have the disadvantages that:
(1)Because operating personnel's operational motion is lack of standardization, or because its safety consciousness does not cause by force to perform a task perfunctorily, seat belt punching Hit test to be possible to not reach expected purpose;
(2)During impact test, no quantizating index is used as to judge, more not intuitively carrying to Impulse Test Result Show, whether qualified be completely dependent on operating personnel's subjective judgment seat belt impact test.
The content of the invention
It is an object of the invention to provide a kind of belt force detector and its detection method, solve existing seat belt The method of testing of pulling force is lack of standardization, inaccurate, because personal supervisor's factor causes test result to there is maximum error.
To solve above-mentioned technical problem, the present invention is employed the following technical solutions:
A kind of belt force detector, including tester main body and suspension strop, the two ends of the suspension strop are provided with clasp, And middle part is provided with length adjuster, one of clasp bypasses fixture and is buckled on length adjuster, the tester main body Two ends are provided with draw ring, and on suspension strop, another clasp is connected with a draw ring of tester main body, tester main body it is another Individual draw ring is connected with seat belt to be measured;
The tester main body includes microprocessor module, measurement module, supply module, reminding module, threshold value setting mould Block, memory module, radio frequency read module and transport module, the measurement module are made up of resistance strain type sensor, and resistance should Variant sensor is connected with microprocessor module by AD sample circuits, the supply module by charge-discharge control circuit and Microprocessor module is connected, and the reminding module includes speaker, alarm lamp and display panel module, speaker, alarm lamp and Display panel module is connected with microprocessor module by sound and light alarm control circuit, and the microprocessor module is adopted by AD Sample circuit is connected with transport module, memory module, and transport module is connected with external record terminal by wired or wireless way.
Further technical scheme is that the suspension strop overall length is 1.1m, and two ends are provided with clasp.
Further technical scheme is that the tester main body is arranged on waterproof and dampproof engineering plastics inside the shell.
A kind of method that belt force detector tests belt force, comprises the following steps:
One end of suspension strop is bypassed periphery the fixture of enough test spaces, and the clasp of the one end is held in outstanding On length adjuster in the middle part of lanyard;
Clasp on the other end of suspension strop is connected with a draw ring of tester main body;
After operating personnel correctly dresses seat belt to be measured, by another draw ring phase of the bracelet of seat belt and tester main body Even;
The supply module for opening tester main body is powered, and opens working condition, to the threshold value setting mould in tester main body Qualified pulling force parameter in block is preset;
Radio frequency read module reads seat belt coding to be measured;
Operating personnel stands into bow step, is firmly moved rearwards by, and applies the power that reversely pulls to seat belt with the weight of body;
When operating personnel applies pulling force to seat belt, resistance strain type sensor transmits increased resistance value to microprocessor Device module, the qualified pulling force parameter that microprocessor module is set according to threshold value setting module judge that resistance strain type sensor is It is no to be pullled by qualified pulling force, if it is decided that after suffered pulling force exceedes default qualified pulling force, microprocessor module control prompting Speaker in module sends that sound, alarm lamp flash and/or display panel module is pointed out, and represents the seat belt to be measured It is qualified;
Increased resistance value is converted into electric signal transmission to memory module by AD sample circuits by microprocessor mould, stores mould Block records the result that the seat belt coding to be measured and microprocessor module of radio frequency read module record storage judge simultaneously, transmits mould The result that seat belt to be measured coding and microprocessor module judge is transferred to external record end by wired or wireless way by block End, completes test.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention differentiates Impulse Test Result based on quantizating index, can avoid invalid seat belt impact test;Due to adopting With the underslung design of buckle, tower material of iron tower structure is not destroyed, do not affect the outward appearance globality of steel tower and concrete bar, do not affect operation Personnel activity;Impulse Test Result, including sound, light, LCD screen are pointed out using various ways;With the addition of radio frequency and read mould Block, can read the electronic tag on seat belt to be tested, and the safe tape recording read is preserved, and be formed test note Record;Wireless and wire transmission module is with the addition of, the test record for preserving can be passed through wireless and wired side inside tester Formula is derived;In detector, software program can adaptive given threshold gear;Systems soft ware can be transmitted according to the setting of RFID models Agreement, using convenient flexible;As tester is not affected by highfield, each electric pressure transmission of electricity is can be widely applied to Circuit.
