Cross bearing to be erected in the installation pedestal 504 of 501 front end of counterweight trolley exhibition arm, handwheel 603 is connected with the rear end of capsizing moment spindle,
One end of raising braiding suspender belt 602 is connected firmly on the capsizing moment spindle 601 between two capstan winches, and the other end is connected firmly in 3 bottom of telescopic joint
Raising braiding suspender belt fix bar 302 on, what the 2 outer wall top of middle part Self-stabilised post base pitch of raising braiding suspender belt 602 was arranged determines cunning
Bypass on wheel.
The dual-locking mechanism of telescopic joint 3 is set, and the first lockable mechanism includes：It is rigidly attached to before capsizing moment spindle 601 by key
The pawl base 701 at end, is symmetrically connected with two ratchets 702 by bearing pin, torsion spring on pawl base；Installation in little car exhibition arm front end
Ratchet brake mount 703 has been bolted on pedestal, and the rear end face of the ratchet 704 coordinated with two ratchets 702 is stopped with ratchet
703 inner chamber seating plane of vehicle seat is contacted, and is arranged and is formed the ratchet platen 705 that face contacts with the front end face of ratchet, in ratchet platen
Heart hole is threadedly coupled with brake handle 706 and is locked by locking nut 707, in the excircle of ratchet platen and ratchet brake mount
Chamber sidewall thread connection.
Second lockable mechanism includes：In the ratchet that the side outer wall of telescopic joint 3 is equidistantly installed with protrusion from top to bottom
304, spine bar mounting ear 202 is provided with the external wall of upper portion of column base 2, the spine bar 203 coordinated with ratchet is pacified by bearing pin, torsion spring
It is mounted in spine bar mounting ear 202, the square hole at a part of Self-stabilised post base pitch spine bar mounting ear of spine bar 203 is stretched in column base
Formed with the ratchet 304 of telescopic joint outer wall and coordinated.Telescopic joint often stretches out 50mm, that is, realize a ratchet kayser, it is ensured that lifting and
During personnel's operation, the hanging of telescopic joint is stablized.
The four side outer wall of top of column base 2 is provided with deep groove ball bearing 201, and the part of each deep groove ball bearing extends into vertical
The inner chamber of base for post section, and the axle of each deep groove ball bearing is secured transverse to the outer wall of column base；In four side of bottom of telescopic joint 3
Wall is again provided with bearing 303, and a part for each bearing 303 extends the outside of telescopic joint, and the axle of each bearing is laterally fixed
Inwall in telescopic joint.
In concrete application, when raising bucket basket is needed, handwheel 603 is rotated forward, handwheel drives capsizing moment spindle 601 to rotate and twine
Suspender belt 602 is woven around raising, suspender belt drives telescopic joint 3 to rise in column base 2, due between column base 2 and telescopic joint 3
Friction be the rolling friction effect of bearing 303 (deep groove ball bearing 201 with), so play lift need not be much, when flexible
After section 3 rises to specified altitude assignment, stop operating handwheel 603, and due to ratchet, the effect of ratchet, telescopic joint can rest on any height
Degree, now, is integrated by the locking of locking nut 707 between ratchet platen 705 and brake handle 706, and ratchet platen 705 is logical
Cross being screwed in ratchet brake mount 703 of its excircle, ratchet platen 705 and ratchet brake mount 703 are from the two of ratchet 704
Individual end face by locked for ratchet in the inner chamber of ratchet brake mount 703, ratchet 704 control pawl base 701 can only one-directional rotation, due to
Pawl base 701 is rigidly attached on capsizing moment spindle 601, and therefore handwheel 603 can only be rotated forward, it is ensured that telescopic joint 3 can when rising
Rest on arbitrary height.Further, since the spine bar 203 on column base top blocks the ratchet 304 of telescopic joint outer wall, it is ensured that flexible
Section unidirectional can only rise, it is not possible to fall, the effect for serving double shield to the safety of operating personnel.When needs will struggle against in the key
During drop, spine bar 203 is released first to the spacing of ratchet 304, be then slightly reverse rolling brake handle 706, now ratchet platen
705 also slightly exit a bit from ratchet brake mount 703, and ratchet platen 705 reduces to the pressure of ratchet 704, therefore ratchet 704
Capsizing moment spindle 601 can be driven anti-in idle running in ratchet brake mount 703 as the effect of gravity, bucket basket are declined with telescopic joint 3
Turn, capsizing moment spindle drives pawl base and ratchet, ratchet to drive ratchet idle running, when needing to stop telescopic joint, need to only rotate forward
Brake handle 706, by locked for ratchet in ratchet brake mount.
