The shortcoming that prior art exists comprises: (1) manual dismounting is wasted time and energy, and labour intensity is big, efficient is low; (2) pin roll end face has the hammer trace, influences presentation quality; (3) there is potential safety hazard in aerial work.
Summary of the invention
The present invention improves prior art, and a kind of crane bearing pin handler is provided.Knock assembling with hydraulic machinery assembling replacement is manual, avoid wasting time and energy of manual dismounting, influence the problem of outward appearance.Also avoided the rope bearing pin to carry out the potential safety hazard that aerial work brings.
The present invention realizes through following technical scheme: a kind of bearing pin handler comprises: door frame; Support is connected the door frame below, has the lifting portion of hanging bearing pin; Hydraulic jack is fixedly connected on the door frame, has telescopically and drives the piston rod that connects bearing pin.
Further, comprise also that slide rail is fixedly connected door frame, the support upper end connects slide rail slidably.
Further, comprise also that suspension ring are fixedly connected with door frame.
Further, also comprise be connected with hydraulic jack pressure regulating part.
Further, also comprise the hydraulic lock that is connected with hydraulic jack.
Further, support directly is connected with door frame.
Further, support comprises at least two lifting portions.
Further, each lifting portion is configured to the structure that height can be regulated respectively.
Through technique scheme, major advantage of the present invention is, device integrates the bearing pin assembling, dismantles, and utilizes pumping plant power, and stable drive, structure are compact, and versatility is good, is applicable to assembling, the dismounting of multiple crane bearing pin.
