Like the structure of fixture, can be improved the stability maintenance of the lifting lug connector 7 and container lifting lug, guarantee the lifting lug connector 7 with
The case where being not in loosening in the fixation procedure of container lifting lug.
The support plate 41 of upper end connection 4 is equipped with CCD camera assembly 8 can be convenient for by the setting of CCD camera assembly 8
When carrying out decentralization top cover suspender, top cover suspender and 1 fixation procedure of top cover are observed, to guarantee top cover suspender and top cover 1
Secure match installation avoids top cover suspender and top cover 1 that installation is fixed or dismantle when separating, due to that can not be observed
Adjustment causes top cover suspender and top cover 1 to collide and the damage of top cover suspender or top cover 1 occurs, then passes through CCD camera assembly 8
The service life for having accordingly increased the top cover 1 and top cover suspender is set, the recycling property of the top cover suspender is improved.
The inner wall of the one end of lower end force piece 5 far from support plate 41 is equipped with chamfering 9, by the chamfering 9 of setting, can into
When row transfers the top cover suspender, it is set in the outer circle of top cover 1 convenient for the top cover suspender, to reduce top cover suspender and top cover 1
The time is transferred in matching when being arranged, slings the time to reduce the top cover 1, and then increase the efficiency of whole operating condition.
Referring to shown in Fig. 1 to Fig. 3, the embodiment of the present invention also provides a kind of hanging method using above-mentioned top cover suspender, packet
Include following steps:
Top cover suspender is transferred, and matches positioning tube 43 with top cover 1；
Lower end force piece 5 is acted on primary shield water tank 3, and upper end connection 4 is fixedly connected with container lifting lug；
After the top cover 1 that adjusting lower end force piece 5 is secured to top cover suspender drive moves upwards a distance, complete
To the lifting operation of top cover suspender；
When carrying out installation top cover 1, decentralization is fixed with the top cover suspender of top cover 1, is located at top cover 1 on vessel 2.
When by the top cover suspender decentralization for being fixed with top cover 1, comprising the following steps: move the top cover suspender for being fixed with top cover 1
It moves to 2 top of vessel, transfers the top cover suspender for being fixed with top cover 1, and adjusting top cover 1 makes it be placed horizontally at container sheet
On body 2, top cover suspender and the disassembly of container lifting lug are removed.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
