The specific purpose tool of industry, in order to find the hidden danger of climb plank in use, accident occurs for prevention, existing that climb plank is periodically tried
Test, existing climb plank experiment is visually observed by operating personnel or carries out self-inspection by stepping on bar operation, and Detection results are poor, it is impossible to
Timely find the hidden danger of climb plank and advance notice is carried out to operating personnel, make security performance during operation low.
The content of the invention
The technical problem to be solved in the present invention is just to provide distribution line cement pole climb plank method for testing performance, solves
The technical problem of potential safety hazard can not be found in time during existing climb plank experiment.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：Distribution line cement pole is used
Climb plank method for testing performance, including pedal, railing rope and metal hook, pedal comprise the following steps successively provided with mark:
Step one：In metal hook mark measurement point A1And A2, and measure A1And A2The distance between a；
Step 2：Pedal is arranged on reference test bar by railing rope, and sign first is marked between railing rope and reference test bar
Note；
Step 3：3500N is applied a load on pedal with 95~105mm/min speed, 5min is kept, it is negative in removal
Before lotus, the second mark is indicated again between railing rope and reference test bar, measurement takes the first mark and the second spacing marked to obtain
The maximum slippage of climb plank is measured, when maximum slippage is not more than 150mm, into step 4 test, when maximum slippage is more than
During 150mm, then return to step one；
Step 4：Removal load, removes climb plank, the A after measurement experiment1And A2The distance between a1, and pass through a and a1
To obtain metal hook permanent set △ a, △ a={ (a-a1)/a } × 100%, when metal hook permanent set △ a are not more than
When 2%, into step 5 test, when metal hook permanent set △ a are more than 2%, then return to step one；
Step 5：Simulation is carried out using same secondary climb plank in 60~75kg tester by two body weight respectively to step on
Bar is operated, and measuring distance is not less than 5m, is circulated 3 times up and down, and tester, which makes, during bar is stepped on faces upward body and action of jumping.
It is preferred that, by pressing plate to applying load on pedal in step 3, and the width of pressing plate is 98~102mm, and pressure
The vertical axis of plate is overlapped with the vertical axis of pedal, can guarantee that the stationarity for being applied to load on pedal, and ensure pedal by
Power is uniform, improves the accuracy rate of test.
It is preferred that, pedal, which is provided with, prevents the rubber blanket of pedal damage when pressing plate applies load, and the thickness of rubber blanket is 3
~5mm, can realize that the load that pressing plate applies is uniformly distributed, prevent stress from concentrating, so as to reduce the damage of pedal, improve test
Accuracy rate, when rubber blanket thickness be less than 3mm when, rubber blanket is fragile, when rubber blanket thickness be more than 5mm when, pedal by
Power is uneven, easily the stressed effect of influence pedal.
It is preferred that, visual examination is carried out to climb plank before step one, and obtain the size of pedal, railing rope and metal hook,
The overall appearance of climb plank can be checked, it is ensured that the security performance of test, and ensure pedal, railing rope and metal hook in peace
In full size range.
It is preferred that, immersion cloth and leaching absolute ethyl alcohol cloth are passed sequentially through before step one, and to mark, wiping 1min is identified respectively
Durability test, the mark after test should be without fuzzy or Loss, and overall mark should clear, complete and firm effect.
In summary, advantages of the present invention：1. by applying load with 95~105mm/min speed on pedal, and
Slippage that can be fast and effectively to climb plank by the first mark and the second mark is measured, and the accuracy rate of measurement is high, sliding
Shifting amount is measured conveniently, and need to ensure the slippage no more than 150mm of climb plank, and return to step is needed when slippage is more than 150mm
One, which carries out second, is tested, and the performance of climb plank is confirmed by the contrast of secondary detection, improves the accuracy rate of test, and
The change of climb plank is observed under the pressurization of load, can quickly find whether railing rope has whether stranded and pedal has cracking existing
As quickly can timely find climbers potential safety hazard that may be present；
2. pass through a and a1To obtain metal hook permanent set △ a, it need to ensure that metal hook permanent set △ a are not more than
2%, when metal hook permanent set △ a are more than 2%, need return to step one to carry out second and test, pass through secondary detection
Contrast to confirm the performance of climb plank, further increase the accuracy rate of test；
Bar operation is stepped on 3. dressing same secondary climb plank by two testers and carrying out simulation, can quickly check and step on bar
When climb plank whether have unexpected roll-off, whether whether metal hook should have stranded and pedal without obvious visible deformation, railing rope
There is cracking phenomena, improve the accuracy rate of experiment.
