Description
Technical field
The utility model is related to engineering machinery fields, more particularly to a kind of adjustable and portable formula hobboing cutter torque measuring trial work
Dress.
Background technology
With the expansion in China city and the increase of population, traffic blocking problem getting worse, in order to alleviate traffic problems
For the restriction of urban development, many cities have all carried out subway planning.By in June, 2017, China's Mainland, which is built up, puts into operation ground
The city of iron is up to 29.
Shield construction method is generally used during subway construction.Shield cutter is as wear-resisting easy in shield construction method
Consumable component, usage amount is larger, especially shield hobboing cutter, has working environment is severe, service load is unstable, impact loaded is big etc.
Feature, consume and service life directly affect quality, efficiency and the cost of driving.Since the cutter ring of hobboing cutter is worn or is damaged,
It needs to repair, for torque as the important parameter in the cutting process of hobboing cutter, measurement method seems of crucial importance.Shield is dug
Into in the process, cutterhead is pushed and is rotated forward, and frictional force is generated between hobboing cutter cutting edge and the rock stratum of contact, and frictional force generation rubs
Wiping torque drives hobboing cutter cutter ring to be rotated around cutter shaft.Friction torque has to be larger than the starting torque of hobboing cutter, just can guarantee hobboing cutter just
Often work.Hobboing cutter torque can be by influences such as abrasions during the workmanship, technological problems and use of hobboing cutter, and torque can be with
It and generates variation using process.
Shield machine open a position inspection when, the detection about hobboing cutter torque be entirely empirically, with tool push cutter ring
Rotation, using can rotate as whether the standard being continuing with, traditional torque accurately detection hobboing cutter must be disassembled
It can measure, increase workload, quantifiable standard can not be given for judging whether hobboing cutter can be continuing with.For TBM
In tunneling process, since hobboing cutter use condition is more severe compared with city underground shield construction, opening a position, it is more frequent to check.
The utility model patent that one number of patent application is 201020602504.8, discloses a kind of shield machine roller cutter torque
Detection device comprising the circular cutter ring snap ring rolled by steel band, cutter ring snap ring opening are provided in the opening with opposite two
Connecting lugs, two connecting lugs use bolt-connection, are welded with lug on the outside of cutter ring snap ring, spiral shell is fixed on lug
Mother, the snap ring in the utility model must be locked with cutter ring contact position can ensure that snap ring is locked with cutter ring, otherwise can not be accurate
Torsion-testing is really completed, and snap ring can not adjust locked position according to cutter ring size, this is during testing torque
It is very inconvenient.A kind of quantifying detecting tool in executable hobboing cutter torque cabin therefore, it is necessary to design.
