The technical scheme that its technical matters that solves the utility model adopts is:
A kind of tight rope device of amplitude variation trolley, comprise the rope sheave assembly, the tight rope assembly, described tight rope assembly comprises bearing up pulley, spacer, the tight rope otic placode, described tight rope otic placode is connected with cart stationary, described bearing up pulley, spacer is installed on the tight rope otic placode by bearing pin, described rope sheave assembly comprises and steel rope bonded assembly reel, described reel is installed in rotation on the dolly, described rope sheave assembly also comprises ratchet, the ratchet otic placode, ratchet, ratchet otic placode and tight rope spanner, described ratchet connects with reel is coaxial, described ratchet is installed on the ratchet otic placode, described ratchet cooperates with ratchet, described ratchet is connected rotationally with the ratchet otic placode, described ratchet otic placode, the ratchet otic placode is installed on the dolly; Described tight rope spanner comprises the tight rope plate, pulls pin, and described tight rope sleeve-board is contained on the ratchet shaft, and the described pin of pulling is plugged on the tight rope plate, and the described pin of pulling cooperates with teeth groove on the ratchet.
Further, described ratchet and spacer are abutted against, and described ratchet, spacer are connected with the ratchet otic placode by bearing pin.
Further, described ratchet is two, and described two ratchets are installed in the both sides of reel.
Further again, described rope sheave assembly also comprises nut, screw, pressing plate, and described pressing plate is provided with the hole, and described screw passes pressing plate captives joint with ratchet, and described nut sleeve is in the end of screw.Two holes are arranged on the ratchet plate, and one of them hole of steel wire penetrating is enclosed within pressing plate on the screw steel rope is embedded on the half slot of pressing plate, with the nut screwing clamping compacting; Again steel rope is wrapped in above the reel.
Technical conceive of the present utility model is: connects with reel by ratchet, detent mechanism, and the rotation of design spanner drive reel, effectively locate by ratchet, use convenient.
After luffing steel rope pine, the driver opens amplitude variation trolley to the arm root, the maintainer pierces within the jib by the maintenance hanging basket, and pull-up tight rope spanner makes the plate pin on the tight rope spanner insert certain detent positions on the ratchet, be that the maintainer can make on the ratchet slot of power, pulling tight rope spanner slowly tightens up the luffing rope, and the ratchet deadweight is blocked till the ratchet, repeatable operation is finished the tight rope purpose.Again on-station position is put in the spanner pull-up, i.e. tight rope spanner disengaging ratchet puts down spanner downwards and gets final product.
The beneficial effects of the utility model mainly show: convenient to use, avoid potential safety hazard.
