Four, description of drawings

Fig. 1 is a hanger structure birds-eye view of the present utility model.

Fig. 2 is front view of the present utility model (cutting open on one side).

Five, the specific embodiment

Below in conjunction with accompanying drawing the structure specific embodiment of the present utility model is elaborated.

By Fig. 1, shown in Figure 2, the utility model includes suspension bracket 2, suspension ring 6 and stay cord 18, stay cord one end is contained on the suspension ring, other end symmetry is contained on the crossbeam of suspension bracket both sides portion, driving device 4 is equipped with at suspension bracket 2 centers, driving device 4 is by the pawl wheel 14 that is contained on the support body, gear 15, drive link 9 and eccentric wheel 11 constitute, extension spring 13 is housed on the pawl wheel 14, the extension spring rope 16 that links to each other with suspension ring 6 is housed in the extension spring 13, pawl wheel 14 with gear 15 be contained in coaxial on, this gear 15 is meshed with gear on the transmission tube that drive link 9 links to each other, drive link is equipped with eccentric wheel 11 on 9 liang of outer ends, eccentric wheel 11 links to each other with the pipe link 12 at suspension bracket 2 two ends, and pipe link 12 is with revolving latch mechanism 1 link to each other (revolve latch mechanism and be existing rotary-locking device commonly used, stay cord and extension spring rope all adopt steel rope) on 2 four jiaos on the suspension bracket.

In order to guarantee result of use and convenient, in the suspension bracket 2 one side crossbeams suspension ring carriage 5 is housed in the heart, be used for the convenient suspension ring 6 of placing; Stay cord 18 two ends are fixed on suspension ring 6 and the suspension bracket 2 with aluminum alloy sleeve and lock shaft 3 compactings respectively, and are added with rope sheath 17; Suspension bracket 2 adopts stressed metal construction, and rigidity is strong, and solid durable, the life-span is long; For guaranteeing accurately to lift freight container, on the crossbeam that suspension bracket 2 one ends are connected and the longeron outside end guide plate 8 and side guide plate 10 are housed respectively; Turnover plate type terminal indicator 7 is housed on the drive link 9.

Service condition of the present utility model is that suspender driving link pawl wheel rotates pawl wheel by the strength of suspension hook lifting, whenever stirs a tooth and can make pawl wheel turn over 90 °; Pawl wheel drives the big gear wheel coaxial with it, big gear wheel and pinion, and by transmission tube drive drive link, doing 180 ° intermittence rotates, drive link drives the pipe link at two ends, promotes to revolve lock again, makes to revolve 90 ° of lock rotations, utilize guide plate to make suspender revolve lock and four jiaos of alignment of a holes of freight container, fall and revolve in the lock entrance angle hole by case; Transmission device action during lifting is revolved the lock rotation and 90 ° case is locked; Continue lifting case is winched to the case pine hook that falls behind the assigned address; Transmission device repeats the front action during recurrence hanging hook, revolves the lock rotation and promptly sets back for 90 °; Suspender and freight container are thrown off when continuing to hoist suspension hook, finish a working cycle.In the use, after revolving lock and forwarding the position to, driving device forces bearing pin to insert in the knock hole of pawl wheel, and the locking ratchet wheel can only rotate 90 ° thereby guaranteed to revolve lock, has eliminated to revolve lock and change phenomenon not in place.

It is to be noted during use:

1, suspender hoists when preparing to enter freight container, and revolving the lock direction must be consistent with the four jiaos of hole directions in freight container top: as differ from 90 °, and sky falls to once adjusting direction earlier, begins operation again.

2, suspender both sides guide plate is close to case two corresponding edge off the hook downwards the time, when guide plate leaned against the case both sides, four jiaos revolved lock and have aimed at container corner hole, get final product off the hook, and the clamping plate that fall put in place and middle wirerope loosens.

3, suspender is set level Shi Xuansuo and should all be entered the case hole on case, and the suspension hook that at this moment hoists then revolves lock and rotates 90 °, indicating device steering lock position, and case is pinned automatically, continues the suspension hook that hoists, and freight container is promptly sling.

4, when suspension hook that container crane is fallen to the desired location, drop down onto that the suspender clamping plate put in place and middle wirerope (being the extension spring rope) loosens, recurrence hanging hook then revolves lock and rotates 90 ° and get back to original position, continues the suspension hook that hoists, and suspender and case are thrown off automatically.

By above-mentioned situation as can be known, the utlity model has following good effect:

1, the utility model has adopted and has revolved the location structure that lock combines with transmission device, forwards the position to when revolving lock After force lock shaft to insert in the locating hole of pawl wheel, the locking ratchet wheel can only rotate thereby guaranteed to revolve lock 90 °, eliminated to revolve to lock and turned to phenomenon not in place;

2, suspender is mechanism's interlocking, can guarantee to be synchronized with the movement, and assembles terminal indicator simultaneously, and promptly the turnover plate type indicating device can be convenient to driver's distant surveillance and revolve the lock rotational orientation, and is safe and reliable;

3, adopt floating type rotary lock structure, revolving lock laterally floating adjustment amount is ± 6mm that the vertical floating adjustment amount is ± 11mm to adapt to the loading and unloading operation of distortion case, broken case;

4, steel rope (stay cord) two ends are fixing with the aluminum alloy sleeve compacting, and add the rope sheath, avoided the steel rope song to split wearing and tearing, prolonged the service life of stay cord greatly, and avoided the past to go up the phenomenon that wire clips interferes with each other more because of restricting, and increased shackle at suspension ring and steel rope termination, be convenient to on-the-spot single more change steel rope;

5, main stressed member has adopted the alloy steel manufacturing, and suspension ring adopt the high strength material solid forging, does not have welding, and is safe, feasible;

6, duel spreader frames one side has been installed the suspension ring carriage, can realize hook and post-job unhook that operation is preceding very easily, has alleviated labour intensity.
