Description
Technical field
The utility model relates to measurement mechanism, particularly relates to a kind of chain block performance parameter measurement mechanism.
Background technology
What the power that pulls adopted is that method of heavily cutting or polish jade with an emery wheel is measured, namely first tested cucurbit is hung up at product testing product, the test load being equivalent to rated load weight is added on hoist lifting hook, and promote the height of 300mm, decline side chain bar during measurement, chain block being pulled chain is fixed, the specified counterweight (counterweight position is as far as possible near tested cucurbit) pulling force value of tested cucurbit is first added pulling on chain of lifting side, add simultaneously and be equivalent to the specified additional weight pulling force value 50%, when unclamp decline side pull chain time, observe the decline situation that lifting side pulls counterweight on chain, if counterweight is when midway stops or accelerating decline, then should suitably increase or reduce the specified counterweight pulling force value, until counterweight can with the effective travel of more uniform speed decline 200mm, then the weight of this counterweight is the numerical value of the surveyed power that pulls, such measurement should carry out three times, get the mean value of these three measurement data, what be this chain block pulls power, then through calculating the efficiency can obtaining collection, the general needs of this measurement granting are repeated multiple times could obtain valid data, if and be applied on large-tonnage chain block, relative heavier of the counterweight of mentioning, therefore the labour intensity measured is large, poor stability.
Utility model content
For the problems referred to above, the utility model provides a kind of chain block performance parameter measurement mechanism.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of chain block performance parameter measurement mechanism, comprise tested chain block, measurement mechanism body, described measurement mechanism body comprises system base and is arranged on the work sprocket wheel on system base, drive unit, on described work sprocket wheel, cover has a chain, described work sprocket wheel is connected by chain with tested chain block, a torque speed sensor is connected in series between described drive unit with work sprocket wheel, described drive unit comprises speed reduction unit, magnetic powder brake, motor, temperature controller, described speed reduction unit, magnetic powder brake, be connected successively by coupling shaft between motor, described motor is connected by electric wire with temperature controller.
Further, described torque speed sensor is each side provided with rolling bearing units for supporting.
Further, the crampon that described tested chain block is provided with is placed with a load.From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
