Between counterweight trolley and the upper end of telescopic joint, be also connected with anti-dumping rope503, prevent that whole mechanism from toppling, improve safety coefficient. In specifically arranging, be provided with bolt at the top of counterweight trolley exhibition arm 501Groove 505, the lower sides of column base pitch 2 is provided with the bolt corresponding with dolly exhibition arm bolt groove position of protrusion, by this boltFurther fixed weight dolly.
The lifting mechanism of telescopic joint 3 is set, and this lifting mechanism comprises: with the capsizing moment spindle 601 of two capstan winches, capsizing moment spindle is logicalCross on the mounting base 504 that bearing bracket stand is located at counterweight trolley exhibition arm 501 front ends, be connected with handwheel 603 in the rear end of capsizing moment spindle, riseThe one end that rises braiding suspender belt 602 connects firmly on the capsizing moment spindle 601 between two capstan winches, and the other end connects firmly in telescopic joint 3 bottomsOn braiding suspender belt fixed bar 302, on the fixed pulley that the middle part Self-stabilised post base pitch 2 outer wall tops of braiding suspender belt 602 arrange, walk around.
The Dual-locking mechanism that telescopic joint 3 is set, the first lockable mechanism comprises: be rigidly attached to before capsizing moment spindle 601 by keyThe pawl base 701 of end, is symmetrically connected with two ratchets 702 by bearing pin, torsion spring on pawl base; In the installation of dolly exhibition arm front endOn pedestal, be bolted ratchet brake mount 703, rear end face and the ratchet of the ratchet 704 coordinating with two ratchets 702 are stoppedVehicle seat 703 inner chamber seating plane contacts, arrange the ratchet platen 705 contacting with the front end face forming surface of ratchet, in ratchet platenHeart hole is threaded with brake handle 706 and locks by locking nut 707, in the excircle of ratchet platen and ratchet brake mountChamber sidewall thread connects.
The second lockable mechanism comprises: the ratchet that is equidistantly installed with protrusion at a side outer wall of telescopic joint 3 from top to bottom304, be provided with sour jujube bar mounting ear 202 in the external wall of upper portion of column base pitch 2, the sour jujube bar 203 coordinating with ratchet is by bearing pin, torsion spring peaceBe contained on sour jujube bar mounting ear 202, the square hole at a part of Self-stabilised post base pitch sour jujube bar mounting ear place of sour jujube bar 203 stretches in column base pitchForm and coordinate with the ratchet 304 of telescopic joint outer wall. Telescopic joint often stretches out 50mm, realizes a ratchet kayser, guarantee lifting andWhen personnel's operation, the unsettled of telescopic joint stablized.
The top four limit outer walls of column base pitch 2 are provided with deep groove ball bearing 201, and a part for each deep groove ball bearing extends into verticalThe inner chamber of base for post joint, and the axle of each deep groove ball bearing is laterally fixed on the outer wall of column base pitch; In four limits, bottom of telescopic joint 3Wall is provided with bearing 303 equally, and a part for each bearing 303 is extended the outside of telescopic joint, and the axle of each bearing is laterally fixingAt the inwall of telescopic joint.
In concrete application, in the time that needs hoist bucket basket 4 time, forward rotation handwheel 603, handwheel drives capsizing moment spindle 601 to rotateAnd being wound around suspender belt 602, suspender belt drives telescopic joint 3 in the interior rising of column base pitch 2, due to rubbing between column base pitch 2 and telescopic joint 3Wipe as rolling friction the effect of bearing 303 (deep groove ball bearing 201 with), thus rise lift do not need much, when on telescopic joint 3Rise to after specified altitude assignment, the handwheel 603 that stops operating, due to the effect of ratchet, ratchet, telescopic joint can rest on arbitrary height, thisTime, between ratchet platen 705 and brake handle 706, be integrated by locking nut 707 lockings, and ratchet platen 705 is by itBeing screwed in ratchet brake mount 703 of excircle, ratchet platen 705 and two ends of ratchet brake mount 703 from ratchet 704Face is by locked ratchet in the inner chamber of ratchet brake mount 703, and ratchet 704 is controlled pawl base 701 can only one-directional rotation, due to ratchetSeat 701 is rigidly attached on capsizing moment spindle 601, and therefore handwheel 603 can only forward rotation, guarantees that telescopic joint 3 can stop in the time risingAt arbitrary height. In addition, because the sour jujube bar 203 on column base pitch top blocks the ratchet 304 of telescopic joint outer wall, guarantee that telescopic joint onlyThe unidirectional rising of energy, cannot fall, and operating personnel's safety has been played to the effect of double shield. When needs fall bucket in the keyTime, first remove spacing to ratchet 304 of sour jujube bar 203, then rotate backward a little brake handle 706, now ratchet platen 705Also slightly in ratchet brake mount 703, exit a bit, ratchet platen 705 reduces the pressure of ratchet 704, and therefore ratchet 704 canWith in the interior idle running of ratchet brake mount 703, due to the effect of gravity, bucket basket 4 declines with telescopic joint 3, drives capsizing moment spindle 601 to reverse,Capsizing moment spindle drives pawl base and ratchet, ratchet to drive ratchet idle running, in the time that needs stop telescopic joint, only needs forward rotation brakingHandle 706, by locked ratchet in ratchet brake mount.
