As shown in Figure 1, I-beam section 2 is arranged on the downside of girder 3.Can walk about for Operation and Maintenance personnel on girder 3, both sides are provided with protection railing, and this girder is the primary load-carrying members of hoisting crane, and other mechanism of hoisting crane can drive this girder to carry out parallel motion.Hoist ceiling crane 1 is suspended on below I-beam section 2, hoist ceiling crane 1 can be conventional or customization hoist ceiling crane, usually lifting mechanism 1-1, operating unit 1-2, suspension hook 1-3, steel rope 1-4 etc. are comprised, lifting mechanism 1-1 comprises motor, drg, retarder, reel etc. usually, wherein the spindle nose 1-11 stretched out is left in motor one end, can be connected with one end of flexible axle 5, drg is configured with manual releasing draw ring 1-12, pull manual releasing draw ring 1-12, can open drg, namely the motor shaft of such motor is in free state.Operation support 4 is arranged on the side of hoist ceiling crane 1, for the operating side of fixing flexible axle 5 and stay cord 6.Flexible axle 5 one end connects the motor shaft head 1-11 of hosting mechanism of electric hoist 1-1, the other end of flexible axle 5 is fixed on operation support 4, and can be connected with long-armed crank 7, flexible axle 5 drives the motor shaft head 1-11 of hosting mechanism of electric hoist 1-1 to turn round by own rotation, and then drive motor axle, retarder and spool turns, and then suspension hook 1-3 is driven to move up and down by steel rope 1-4.One end of stay cord 6 connects the manual releasing draw ring 1-12 of lifting mechanism 1-1, to open drg, the other end of stay cord 6 is fixed on operation support 4, and can be connected with long-armed hook 8.
Wherein, with reference to figure 1, long-armed crank 7 and long-armed hook 8 fixed placement when normal operation, above girder 3, only uses when accident.Long-armed crank 8 can be operated by operating personal when accident, rotates the operating side 5-1 of flexible axle 5, and then drives flexible axle 5 and motor shaft head 1-11 to rotate.Parts when operation support 4, flexible axle 5, stay cord 6, long-armed crank 7, long-armed hook 8 are all emergency operations.
Similar function can be realized by other forms of manual driving device for the long-armed crank 7 in above-described embodiment.And also can realize similar function by other device for long-armed hook 8.Because the selection art technology of concrete device can be selected according to the actual requirements flexibly, therefore do not repeat at this.
Fig. 3 is the part A enlarged diagram of Fig. 1.Referring to figs. 1 to Fig. 3, the operating side 5-1 of flexible axle 5 is fixedly installed on operation support 4, and the side of operating side 5-1 is provided with projection 5-11 and projection 5-12, the axisymmetrical of the relative operating side 5-1 of projection 5-11 and projection 5-12.
Fig. 4 is the part B enlarged diagram of Fig. 1.With reference to figure 4 and Fig. 3, one end of long-armed crank 7 is provided with a shift fork head 7-1, the bottom of shift fork head 7-1 has cavity, the form fit of cavity and operating side 5-1, the bottom of shift fork head 7-1 is provided with two groove 7-11, the axisymmetrical of two groove 7-11 relative shift fork head 7-1, because shift fork head 7-1 has middle control chamber, therefore in fact two groove 7-11 are arranged on the housing of shift fork head 7-1, two groove 7-11 mate with the projection 5-11 of operating side 5-1 and projection 5-12 respectively, when operating side 5-1 is inserted in the cavity of shift fork head 7-1, projection 5-11 and projection 5-12 can snap in two groove 7-11 respectively.
Fig. 5 is the C enlarged schematic partial view of Fig. 1.As shown in Figure 5, in addition, with reference to figure 1, a draw ring 6-1 can be set in the operating side of stay cord 6, and hook draw ring 6-1 by the U-shaped gib head 8-1 of a long-armed hook 8.Can be operated by operating personal during accident, hook the operating side 6-1 of stay cord 6, pull the manual releasing draw ring 1-12 of drg by stay cord 6 and make it rotate the angle of setting, and opening the drg in lifting mechanism 1-1.
Referring to figs. 1 to Fig. 5, for the ease of operated by personnel's flexible axle 5 and stay cord 6, operation support 4 is arranged on the side of hoist ceiling crane 1, the operating side 5-1 of flexible axle 5 is fixedly installed on operation support 4, and the operating side 6-1 of stay cord 6 is fixedly installed on operation support 4.And the operating side 5-1 of flexible axle 5 can rotate by opposite brackets 4, the operating side 6-1 of stay cord 6 can be lifted by opposite brackets 4.
In addition, girder 3 is parts of hoisting crane carrying structure, other mechanism of hoisting crane can drive this girder to carry out parallel motion (all the other structures of hoisting crane, mechanism is not shown), the I-beam section 2 that girder is installed for 3 times is hung with hoist ceiling crane 1, the operating unit 1-2 of hoist ceiling crane 1 can drive hoist ceiling crane 1 self to carry out horizontal rectilinear motion along I-beam section 2, such hoist ceiling crane 1 can make level under the drive of girder 3, perpendicular to the cross motion of girder, the longitudinal movement being parallel to girder can be made under the drive of operating unit 1-2, lifting mechanism 1-1 can drive suspension hook 1-3 up-and-down movement, weight can be realized like this to be carried to another vicinal function from a place.
Composition graphs 1 to Fig. 5 sketches a kind of operating process of the present invention.After the motor of the lifting mechanism 1-1 of hoist ceiling crane 1 breaks down or has a power failure, operating personal climbs up girder 3, but operating personal cannot be directly adjacent to hoist ceiling crane 1, at this moment operating personal first can hook the operating side 6-1 of stay cord 6 by long-armed hook 8, firmly pull-up again, the drg manual releasing draw ring 1-12 of lifting mechanism 1-1 in hoist ceiling crane 1 is pulled by stay cord 6, and make manual releasing draw ring 1-12 rotate the angle of setting, finally open drg, make motor shaft in lifting mechanism 1-1 be in free state.Then operating personal is by long-armed crank 7, by its lower end--shift fork head 7-1 is enclosed within the operating side 5-1 of flexible axle 5, shake long-armed crank 7, the motor shaft head 1-11 of lifting mechanism 1-1 in hoist ceiling crane 1 is driven to rotate by flexible axle 5, and then drive the motor in lifting mechanism 1-1, retarder, spool turns and then drive suspension hook 1-3 to move up and down, to complete set work by steel rope 1-4.Like this, Operation and Maintenance personnel, after accident occurs, long-rangely can manually manipulate the work that hoist ceiling crane 1 completes requirement, realize emergency operation.As emergency operation device need be arranged at operating unit, can refer to lifting mechanism and arrange equally, so that service personnel carries out remote control.
In sum, the present invention adopts hoist ceiling crane to substitute traditional monkey, instead of two girder by single girder, by emergency operation devices such as operation support, flexible axle, stay cord, long-armed crank, long-armed hooks, can realize the emergency operation when accident condition of lifting mechanism, operating unit.So can simplify crane span structure, simplify monkey, significantly reduce costs.Meanwhile, above-described embodiment solves Operation and Maintenance personnel be difficult at an arbitrary position easily close to hoist ceiling crane by arranging long-armed crank and long-armed hook, causes being difficult to the problem with handwheel Direct driver hoist ceiling crane.
Although exemplary embodiment describe the present invention with reference to several, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Spirit of the present invention or essence is not departed from because the present invention can specifically implement in a variety of forms, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and should explain widely in the spirit and scope that claims limit, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claims and contained.
