Description
Technical field
The present invention relates to the new method of a kind of buffer of elevator test recovery time.
Background technology
Buffer is a kind of important safety of elevator, is generally arranged at the bottom of the stroke of lift car and counterweight
Portion.When elevator surmounts bottom or top layer, car or counterweight cushion at collision, buffer absorb or consume the kinetic energy of elevator,
So that car or counterweight slow down safely until stopping.
Buffer is one of important safety parts of elevator.According to " elevator type approval test code " (trying) requirement, buffering
Device can must be gone into operation after type approval test mechanism form pass the test.And before elevator comes into operation after installing, special equipment is checked
Testing agency should by " elevator surveillance inspection procedure " requirement, hydraulic bjuffer working condition is implemented confirmatory supervision and inspection (note:
" elevator surveillance inspection and periodic inspection rule traction and the forcibly driving elevator " that will issue enforcement also has same control gauge
Fixed).Above-mentioned two technical specification of security all has the clear and definite inspection content requirement of corresponding clause and method to hydraulic bjuffer, as
8.2(in " elevator surveillance inspection procedure " annex 2 " elevator surveillance inspection content requires and method " the 8th article " function test " this
Item is significant terms) be so to describe: " need to carry out hydraulic buffer resetting and test, 120s should be not more than resetting time.”
The corresponding method of inspection is: " car, under no-load condition, declines with inspection speed, by buffer full compression, from car start from
Open buffer moment to rise, until buffer reinstatement.Observe and use manual time-keeping." from above-mentioned, answering of hydraulic bjuffer
Bit time is an important indicator characterizing its security performance, accurately measures its resetting time, it is possible to for judging the property of buffer
Good and bad can provide strong evidence.Obviously, the most general method observed with timer combination that uses determines buffer
Resetting time is inadequate science, accurate, it is necessary to research and develop more science, accurate and safe and efficient method of testing, emphatically
Solve following problem:
(1) accuracy: accurately catch starting point and terminating point that buffer recovers, discharge the interference signal being likely to occur,
Output reliable results data；
(2) practicality: can not operate in sedan-chair hole owing to test starts rear personnel, tester is wanted test data to be passed in real time
It is passed to host computer, and can be controlled by host computer, be effectively improved safety and the efficiency of test；
(3) ease for use: tester can be portable, simple to operate, and objective interface is easy-to-use.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art and meet detection accurate, practical, easy-to-use, the invention provides a kind of electricity
The new method of ladder buffer test recovery time, the method, with single-chip microcomputer as control core, makes to be arranged on light by clamping device
Rubber wheel on grid encoder axle contacts with buffer guide post, guide post drive grating encoder axle to rotate, to single-chip microcomputer
Signal is provided, thus judges the starting point and ending point that buffer recovers, calculate buffer recovery time, and can be at control box
Test result is shown in real time on display screen and mobile terminal screen.The clamping device of test instrunment can be advised according to the model of buffer
Lattice difference is adjusted, and instrument is easy for installation, simple to operate, precision is high.
The technical solution adopted in the present invention is: utilize buffer mobile drive of guide post in Recovery Process to be arranged on
Rubber wheel on grating encoder rotates and catches starting point and the terminating point that buffer recovers, thus reaches to calculate buffering and recover
Time judges the most satisfactory purpose of buffer.The pulse signal of grating encoder output is received by single-chip microcomputer and counts
Calculation processes, and exports display screen display the recovery time of gained, and can be sent to intelligent mobile terminal by bluetooth transmitters.
The method is easy for installation, simple to operate, precision is high, test result can real-time radio transmission, eliminate use at present observe and
The method that timer combines determines operation inconvenience resetting time of buffer, and precision is low, the deficiency that limitation is big.
Compared with prior art, the invention has the beneficial effects as follows:
(1) present invention is to have abandoned current employing observation and timer knot completely with the maximum difference of prior art
The method closed determines the method for the resetting time of buffer, utilizes high sensitivity output and the height of single-chip microcomputer of grating encoder
Speed computing, can accurately calculate the recovery time of buffer, it is ensured that the reliability of test result, the essence of test is greatly improved
Accuracy.
(2) by Bluetooth transmission function, can be real-time transmitted to test result the mobile terminal of software kit is installed such as
On smart mobile phone, notebook computer, it is possible not only to wireless receiving data, also can instruct by wireless transmission, tester is controlled.
During test, staff is not required to stop at the end, hole, only need to monitor in real time outside elevator, it is ensured that the safety of test process.
(3) combining the practical situation that test job is on-the-spot, the present invention adapts to the buffer of major part model specification, and installs
Conveniently, being easy to carry, simple to operate, objective interface is very clear, the workload of staff is greatly reduced, improves work
Efficiency.
