Description
[technical field]
The utility model is related to field of measuring technique, specifically a kind of detachable dicycly measurement apparatus.
[background technology]
At present, China is more than 200,000 and annual with about 10% number with escalator and moving sidewalk quantity
Amount is increasing, according to the existing escalator of China and moving sidewalk technical specification and technical standard, these escalators and
Moving sidewalk either in installation and debugging or supervision and inspection every require the speed of service, braking distance, stop slowed down
Degree index carries out to allow to come into operation after detection is qualified, therefore, braking distance, stop deceleration, the inspection of speed of service parameter
Survey is that a workload is big, requires technical work high.
By literature search and patent retrieval, and industry investigation, at present to the speed of service, braking distance testing equipment and
Technology it is representative have following 3 kinds：
1. existing inspection rule is to escalator and moving sidewalk speed, the detection of braking distance；
Existing test is implemented by the way of tape measure is combined using handmarking, and specific testing scheme is：In ladder
Level, pedal, skirt panel carry out mark, then after operating escalator operation to normal speed, when escalator operation is to marking weight
Emergency stop switch is pressed during conjunction, with tape measure step apron board marker distance is again then braking distance.
The detection does not possess the technological means of the braking deceleration of detection escalator and moving sidewalk, its measurement staircase
Also due to test process is complicated, braking distance and the speed of service are tested and can not completed simultaneously for the speed of service and staircase brake distance,
Measuring accuracy is difficult to ensure by man's activity.
2. the staircase brake distance meter that Shenzhen City Special Equipment Safety Test Inst. researches and develops；
The principle of the measuring instrument is rotated using measuring instrument runner, built-in sensors sensing runner moving situation, and by pulse
Signal issues counter and carries out signal conversion, then is transmitted to CPU processing datas, calculates braking distance, calculates the starting of braking distance
Point is the moment point that emergency stop switch is pressed by trigger switch, is so also achieved that synchro measure.
During using the apparatus measures braking distance, measuring instrument is contacted with step pedal, measuring instrument runner can be with step one
Rise and rotate, when staircase reaches normal speed, go to press emergency stop switch, the complete stop of staircase using measuring instrument touch switch
Afterwards, measuring instrument can show the braking distance of staircase.
The inspection equipment does not possess the technological means of the braking deceleration of detection escalator and moving sidewalk equally, by
Common revolution counter is similar in hand-held metering system, the support without specialty, only testing wheel contact escalator treadboards, operation
When measuring instrument runner and step pedal be very easy to produce deflecting, slips, bounce etc. that artificially interference problem can influence to a certain degree
Measurement result.
3. the escalator brake safe performance detector that Anhui special equipment Inspection Research institute researches and develops；
Three velocity pick-up modules are fixed using the machinery mount of special design, collection both sides handrail and three, pedal lead to
The speed data of road whole process, then will be passed on portable instrument main frame by three cables, at main frame intelligent data
Reason, calculates three passages and opens braking acceleration, average speed, braking distance, sync rates and speed deviations situation.
Although the inspection equipment solve the problems, such as to test start and stop acceleration, while also having discharged some by mounting bracket
The artificial disturbing factor for participating in measurement, but this instrument host volume is big, and weight support frame is big, and installation needs time etc. for instrument
Transport, the test of device are all with certain difficulty, it has not been convenient to which reviewer detects.
For case above, the utility model is required according to national new standard GB16899-2011, with reference to existing inspection
Rules and methods, have developed a kind of detachable dicycly measurement apparatus, it is not necessary to which mounting bracket, test job can only rely on one
Individual compact instrument just can be completed, and simplified test process to greatest extent and reduced the error of manual operation.
[utility model content]
The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of detachable dicycly measurement dress
Put, compact structure, constructed using two-wheel, it is not necessary to which specific supports are installed, save the testing time and increase the reliability of detection.
To achieve these goals, a kind of detachable dicycly measurement apparatus, including two wheels, escalators are designed
Measurement apparatus and handle, it is characterised in that escalator measurement apparatus one end is provided with testing wheel, testing wheel is driven in test main frame
The code-disc of split type digital encoder rotate, the escalator measurement apparatus other end is connected with connecting seat, is provided with connecting seat
Rotary axle box, rotary axle box is connected with rotary shaft, and rotary shaft is connected with wheel, with handle one end at the top of escalator measurement apparatus
Connection, handle is in concave shape, and two wheel contacts escalator step tests, the handle other end is attached on fishback, is formed
Three point contact.
Described handle and escalator measurement apparatus detachable connection.
Described connecting seat and escalator measurement apparatus detachable connection.
Compared with the existing technology, combining structure simple possible the advantage is that the utility model：
1) do not need specific supports to install, save the testing time；
2) compact structure, convenient test and durable in use；
3) two-wheeled contact escalator step test, handle is attached on fishback, three point contact, Stability Analysis of Structures, instrument
Will not laterally or longitudinally slide, test data is unaffected；
4) by after handle, the dismounting of subtest wheel, the measurement apparatus can also be as the part of other test events, such as to limit
Fast device rope speed carries out speed verification.
