Description
Technical field
The present invention relates to a kind of construction machinery, the construction lift of especially a kind of safe transmission.
Background technology
Lift of being constructed in various engineerings plays an important role, and can accelerate the progress of engineering, reduce the labor of worker
Fatigue resistance.It is but therein main former therewith problem appear to is that there is the generation of the accident of construction lift during site operation
Because being because caused by the transmission failure of lift.Current construction lift mainly has hawser transmission and turbine and worm transmission,
During running over time, hawser and gear meeting senile abrasion, and then cause the generation of accident.
Some present enterprises have begun to the drive mechanism using rack-and-pinion, but tooth form is worn during actual job
Seriously, wear phenomenon just occurs long very much for the lift rack-and-pinion usage time of constructing, it is necessary to which frequent more gear changing, causes to safeguard
The increase of cost；Do not debug when seated, in use cage deformation, roller displacement etc. cause the engagement of rack-and-pinion it is excessively loose,
The change of tension or contact area, add running danger coefficient.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of service life length, the good construction lift of security.
In order to solve the above technical problems, the invention provides a kind of construction lift of safe transmission, including：Car, hand
