Shown in Fig. 1,2,3, cross bar socket 4,5 is made up of short tube 4.1 and latch 10.Short tube 4.1 is welded on the middle part of two oblique vertical rod 1 upper top intersections or little cross bar 3, and is parallel with leger 2.Latch 10 inserts in the radial hole of short tube 4.1 and leger 2 ends.
The use operating process of this hanging apparatus: as shown in Figure 1, 2, 3, tiltedly vertical rod of detachable one-tenth left side during resettlement, right tiltedly vertical rod and leger 2 three parts.Running roller stop assembly 6 and leger 2 together, tiltedly vertical rod is together for rolling wheel actuating assembly 8 and a left side.Utilize latch 10 in the cross bar socket 4 at operation field, just above-mentioned three parts can be assembled into one.If it is lower that sling height requires, leger 2 can be inserted on the cross bar socket 5.After frame is in place,, the running roller stop assembly 6 on the leger 2 is locked in appropriate position according to by the position and the angle of inclination of lifting workpiece.Operate rolling wheel actuating assembly 8 then, steel rope 7 is lengthened, make movable pulley 22 and suspension hook 23 drop to appropriate height.Suspension hook 23 non-perpendicular (oblique) tangles and (is for example hung workpiece, diesel cylinder sleeve or Piston and rod assembly), operate rolling wheel actuating assembly 8 again, it is short that steel rope 7 is received, movable pulley 22 and suspension hook 23 just rise along non-perpendicular direction, finish non-perpendicular (oblique) lifting operation.In this lifting process, running roller 16 is locked on the leger 2 by the backing block 39 below it, can be because of not being subjected to the oblique pulling shift position.
Running roller stop principle of work: as shown in Figure 7, running roller 16 can freely roll on leger 2, and stop at an arbitrary position.Press big ratchet handle 29 at first downwards, make pull bar 32 drive big ratchet 26 and move up, as shown in Figure 6, make big ratchet 26 be separated from ratchet on the large ratchet 15.Stir big handle 25 then, as shown in Figure 7, big handle 25 drives adapter sleeve 33, interior six square bolts 24 and castellated shaft 34 and rotates.Castellated shaft 34 drives eccentric wheel 37 again and rotates an angle, the cylindrical of eccentric wheel 37 is upwards compressed withstand backing block 39 below.Because the last cambered surface of backing block 39 has some anti-skidding teeth, so backing block 39 just is locked at running roller 16 on the leger 2.At this moment, upwards stir big ratchet handle 29 again, the big ratchet 26 among Fig. 6 is snapped in again in the ratchet of large ratchet 15, big handle 25 promptly is locked in place, and backing block 39 just is locked in running roller 16 position that requires on the leger 2 firmly.Carry out non-perpendicular (oblique) lifting operation then, not only convenient but also safe and reliable.
Rolling wheel actuating principle of work: shown in Fig. 9,10,11, one or two rolling wheel rocking handle 9 is inserted in left and right two spline housings 46.When the needs cw shakes right rocking handle 9, earlier the little ratchet handle 55 in the right side is pulled outwardly out, righter lock dog 54 is buckled, make clavula pawl 58 be separated from right clavula wheel 42, just can shake right rocking handle 9 by cw then.At this moment, though left little ratchet is stuck in the left clavula wheel 41, because be one-way lock mechanism, so also can clockwise rotate, conter clockwise then locking can not rotate, and prevents to reverse out of control.When the needs cw shakes left rocking handle 9, earlier right lock dog 54 is pushed aside, make right clavula pawl 58 returns block right clavula wheel 42, again the little ratchet handle 52 in a left side is pulled outwardly out, again left lock dog 51 is buckled, made left clavula pawl 58 break away from left clavula wheel 41, just can shake left rocking handle 9 by cw then.At this moment, right clavula pawl 58 also has the unidirectional locking function, prevents to reverse out of control.If left and right two clavula pawls 58 insert respectively in left and right two clavulas wheel 41,42 simultaneously, then forward and reversely all can not shake, belong to complete lockup state.At this moment, steel rope 7 can not lengthen, and can not receive weak point again.According to the requirement of lifting operation, can change the aforesaid operations mode at any time, very flexible and safe and reliable.
