For realizing the rotation of mechanism, the rotary column 105 being plugged on sleeve 104 is set, be inserted under the rotary column of sleeve innerHalf fixed cover is connected to the taper roll bearing 106 mating with sleeve diameter, and the first half of rotary column is square tube; Setting is plugged on and turnsSquare-tube type column base pitch 2 in the square tube of post and be plugged on the telescopic joint 3 on column base pitch 2, in the external wall of upper portion of telescopic joint 3Integral type is provided with limiting platform 301, and the sidepiece of bucket basket 4 is installed with laterally extending transverse arm 401, and this bucket basket is with the side on its transverse armShape casing hanger is connected on the top of telescopic joint, and prevents from by the limiting platform of telescopic joint is spacing.
Counterweight trolley 5 is set, and the sidepiece of counterweight trolley is installed with laterally extending exhibition arm 501, and counterweight trolley is opened up arm with itOn square casing be articulated on rotary column 105, be provided with the roller 502 coordinating with circular orbit 103 in the bottom of counterweight trolley, rollThe wheel shaft of wheel is arranged on counterweight trolley bottom by bearing. 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 lockable mechanism of telescopic joint 3 is set: this lockable mechanism comprises: be rigidly attached to capsizing moment spindle 601 front ends by keyPawl base 701, is symmetrically connected with two ratchets 702 by bearing pin, torsion spring on pawl base; At the mounting base of dolly exhibition arm front endOn be bolted ratchet brake mount 703, the rear end face of the ratchet 704 coordinating with two ratchets 702 and ratchet brake mount703 inner chamber seating plane contacts, arrange the ratchet platen 705 contacting with the front end face forming surface of ratchet, the centre bore of ratchet platenBe threaded with brake handle 706 and lock by locking nut 707, the excircle of ratchet platen and ratchet brake mount lumen sideWall is threaded.
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 the time that needs fall bucket in the key, can rotate backward a little brake handle 706, now ratchet platen 705 is also slightlyIn ratchet brake mount 703, exit a bit, ratchet platen 705 reduces the pressure of ratchet 704, and therefore ratchet 704 can be sour jujubeThe interior idle running of wheel brake seat 703, due to the effect of gravity, bucket basket 4 declines with telescopic joint 3, drives capsizing moment spindle 601 to reverse, capsizing moment spindleDrive pawl base and ratchet, ratchet to drive ratchet idle running, in the time that needs stop telescopic joint, only need forward rotation brake handle706, by locked ratchet in ratchet brake mount.
