The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, a kind of RAM packaged type double-box hanger, comprise middle lock box plate 1, be respectively equipped with tapered end hole 2 on four jiaos of the middle lock box plates, be provided with case bar hole 3 perpendicular to central axis position, tapered end hole, that bearing fit has case bar (not shown) in the case bar hole, the other square position limiting clamp base plate 5 that is provided with in case bar hole, parallelly with former case bar centerline hole on the described middle lock box plate set up auxiliary case bar hole 6, the described top, case bar hole of assisting is provided with auxiliary position limiting clamp base plate 7.Described assisting in the case bar hole is connected with case rod bush 8, the second ejector pin bar 4 of pegging graft in the described case rod bush.Described the second ejector pin bar comprises ejector pin bar body 4-1 and induction cap 4-2, and described ejector pin bar body upper end and induction cap are spirally connected, and radially are provided with locking pin-and-hole 4-3, insert the resilient pin (not shown) in the locking pin-and-hole.
Principle of work
When adding suspender lifting freight container before the second ejector pin since former ejector pin bar at the inside line (for hanger twist is locked into the case hole, being extended by land side direction sea side) of hanger twist lock, so lock not the inlet hole and when being stuck in casing sea side when revolving, the ejector pin bar also can be responded to (spacing collection ejector pin signal, namely confirming case), can unblank or block action, this moment as revolve pintle hook lock and live the position and rotatably then revolve lock and unblank or block action carries out, as unblank then to revolve pintle hook lock in casing sea side, can't move; Such as the successful freight container of then can slinging of locking, revolve lock and really do not lift freight container in the case hole right this moment, (8 freight containers that revolve the lock lifting are at this moment few lifting power of revolving lock at least, and occuring, homonymy two revolves lock all outside the case hole during locking, actual 6 revolve lock lifting freight container, very easily cause the case accident of falling).
When adding suspender lifting freight container behind the second ejector pin in (keep in the situation of former ejector pin invariant position and carry out), the position of the second ejector pin in the outside of hanger twist lock namely when revolving when being locked into the cartonning hole ejector pin masthead in casing sea side; As it is outside in casing sea side to revolve pintle hook lock, the unsettled casing that do not contact of ejector pin bar then, this moment unassured case signal (will case spacing move to the second ejector pin place gather this signal be the case signal carry out open locking and move), move without open locking this moment, the unassured case signal of suspender, the maintenance of attonity notice, freight container is not sling can not cause and is fallen case.Guarantee the suspender operational security.
Keep the container operation safety after original mechanical interlocks ensures lifting.Add the second ejector pin bar and limit signal moved to making coming into effect accurate operation from the case link and guarantee safty hoisting herein, accomplish to lift by crane for full inlet hole.Reach safe operation and ensure requirement.
Mechanics: outside keeping former mechanical interlock protection, safe and efficient case is avoided moving because revolving outside the lock when guaranteeing normal operation; cause " false sense is answered " lifting; because ejector pin is tapered end case outermost, so this ejector pin induction limit signal is accurate, realize safe in operation.
In the program: the second ejector pin and the induction of mechanical chain ejector pin of middle lock random angle is spacing, the ejector pin at other three angles in parallel after the series connection (ejector pin at other three angles is also so processed), this operating mode program segment, guarantee that suspender is all revolving in the locking angle fitting case eye at normal case and all tapered ends, carries out effective open locking.
Working process
The first, the measurement related data is as follows: measure actual container corner seating size: it is long to revolve lockhole: 124mm; Wide: 65mm; Cone head part developed width: 100mm before the RAM suspender tapered end; Vertically wide: 57mm; The inboard 10mm of ejector pin position tapered end place, diameter is 30mm.Revolving lock sheath condition amount: 6mm throws when suspender tapered end entrance angle accessory revolves lockhole and removes sheath condition amount and have developed width that the actual gap amount of 18mm is arranged, axial clearance amount 8mm, case in " V " font to two gap value data deficiencies or " driving dull formula " case so that tapered end forms;
The second, confirm the second ejector pin bar point of addition: add the under casing place (case face position is for parallel from the beginning of 45 degree near tapered end) that the second ejector pin bar (diameter is 30mm) should be installed on the outer skew back miter angle of tapered end;
Three, perforate is added and the spacing position of affirmation installation induction.
Four, test run is normal, is the situation generation of box after the locking outside casing without tapered end, revolves lock not in the position, and the signal that namely loses induction can't hoist safety assurance.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
