Description

A kind of quick method of calibration of wide range running scale

Technical field

The invention belongs to calibration technology fields of driving a vehicle, and in particular to a kind of quick method of calibration of wide range running scale.

Background technology

For wide range running scale because by size truck position, position is different, the levelness of scale body is different, be weighed object height and Influences, the weighing precisions such as weight size and swing stabilization time, movable pulley lubrication circumstances and environmental factor also accordingly occur Variation.Wide range：Refer to running scale full scale and be more than big specification truck scale range 150t, verification can not be measured with truck scale and substituted Object, the quality standard device that the verification of wide range running scale uses use a suspender mostly, are such as verified with standard test weight, and precision is high, But counterweight is loaded and unloaded with truck crane or traveling crane, the personnel needed are more, preparation is long with the checking procedure time, efficiency is low.Such as with scattered Substitute is easy in checking procedure to slide, dangerous, weight accuracy is low；More than the big substitute of truck scale maximum capacity range, It can only be weighed with running scale itself, weight accuracy is lower, and the calibration of its traditional method of calibration is not directed to and uses process and shape State, which is selectively simulated, uses process and state.The verification only review to self-aligning after traditional running scale calibration, and It is not the verification to being weighed in object measurement process meaning.

Invention content

In order to compensate for the shortcomings of the prior art, the present invention provides a kind of quick methods of calibration of wide range running scale.

The present invention is achieved through the following technical solutions：

A kind of quick method of calibration of wide range running scale, includes the following steps：

1) object suspender and its two haulage vehicle base dimensions, travelling crane hook, hanging beam size design schools are weighed according to running scale Specific weight suspender appearance and size is tested, be allowed to and travelling crane hook and is weighed object suspender haulage vehicle and matches；

2) the sum of upper suspender counterweight and dead weight are designed and is weighed object suspender weight to load, the sum of lower suspender counterweight and dead weight To be weighed object maximum nt wt net weight；

3) being flexible coupling between two suspenders of design：Trunnion upper and lower side above and below when the length being flexible coupling is more stacked than above and below two hanging scaffolds The long 500mm in the distance between face is flexible coupling between trunnion end flange lower end and hanging scaffold with chain limit；

4) according to counterweight suspender size, counterweight size and specification are designed；

5) accurate under size truck position, height under hook and movable pulley normally lubrication under the conditions of running scale normal operating condition Standby verification running scale；

6) running scale driving string is hung into two verification specific weight suspenders, calibrates maximum capacity point；

7) lower verification specific weight suspender is put down, verification is weighed object suspender weighing point；

8) string hangs two suspenders again, is placed into designated position, verification terminates.

Further, the step 4）The counterweight of middle design and counterweight and counterweight and the mutual concave-convex clutch of suspender, avoid counterweight Sliding is fallen.

The beneficial effects of the invention are as follows：Solve traditional wide range running scale verification mode verification efficiency and checking precision contradiction The problem of, when verifying running scale, using normal use process and state as foundation, make verification state simulation use state, solves Wide range running scale tradition verification mode does not require verification status condition targetedly, and reduction process and state differ The unknown uncertain error brought is caused, the security risk that substitute present in checking procedure or counterweight slide is eliminated.

Specific implementation mode

Specific embodiments of the present invention are given below, for further explaining the composition of the present invention.

A kind of quick method of calibration of wide range running scale of the present invention, includes the following steps：

1) object suspender and its two haulage vehicle base dimensions, travelling crane hook, hanging beam size design schools are weighed according to running scale Specific weight suspender appearance and size is tested, be allowed to and travelling crane hook and is weighed object suspender haulage vehicle and matches；

2) the sum of upper suspender counterweight and dead weight are designed and is weighed object suspender weight to load, the sum of lower suspender counterweight and dead weight To be weighed object maximum nt wt net weight；

3) being flexible coupling between two suspenders of design：Trunnion upper and lower side above and below when the length being flexible coupling is more stacked than above and below two hanging scaffolds The long 500mm in the distance between face is flexible coupling between trunnion end flange lower end and hanging scaffold with chain limit；

4) according to counterweight suspender size, counterweight size and specification are designed；

5) accurate under size truck position, height under hook and movable pulley normally lubrication under the conditions of running scale normal operating condition Standby verification running scale；

6) running scale driving string is hung into two verification specific weight suspenders, calibrates maximum capacity point；

7) lower verification specific weight suspender is put down, verification is weighed object suspender weighing point；

8) string hangs two suspenders again, is placed into designated position, verification terminates.

Further, the step 4）The counterweight of middle design and counterweight and counterweight and the mutual concave-convex clutch of suspender, avoid counterweight Sliding is fallen.
