Description
Technical field
The invention belongs to technical field of ships, in particular to the abridged edition type hoisting test method of a kind of heavy lift carrier.
Background technique
With the needs that marine cause develops, operation on the sea is increasingly enlarged, this requires to get over to marine large lifting equipment
Come higher.Rising on heavy lift carrier enables the manufacture requirement hung high, and difficulty is big, wherein acting enable the hoisting test hung be mostly important one
Ring, the purpose of test are to examine the installation integrity of crane, correctness, functional reliability, and verify whether performance indicator accords with
Close design and test program requirement.Therefore rising and enabling the hoisting test hung is a comprehensive complicated engineering.Existing heavy lift carrier
Hoisting test method, be usually transported on ship from harbour by huge heavy weight, order then used to hang and match with huge heavy weight
Conjunction is tested, but the test method have the defects that it is certain: in the test method, need to by huge heavy transporting heavy things to ship,
Hoisting test is carried out again, process is more complicated, meanwhile, extraneous weight need to be used, will increase cost, and transports weight to enhance labor
Fatigue resistance.
Therefore, a kind of abridged edition type hoisting test that can reduce cost, labor intensity and easily operated heavy lift carrier is researched and developed
Method is necessary.
Summary of the invention
It can reduce cost, labor intensity the technical problem to be solved in the present invention is to provide a kind of and easily operated hang again
The abridged edition type hoisting test method of ship.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of abridged edition type hoisting test method of heavy lift carrier,
Method includes the following steps:
(1) experiment of weighing hoist: weighing examines the test hoist approved by shipowner's ship, hangs/self-propelled hatchway cover
P25 hangs/self-propelled hatchway cover P26, and two deck D5, two deck D 12, two deck D 7, two deck D6 and several weight are not
One 1x hanging block；
(2) overload test:
A.1# crane main hook load raising test: hoist includes hanging/self-propelled hatchway cover P25, hangs/self-propelled cabin
Cover board P26, two deck D 5, two deck D 6 and two deck D 12；To be hung using 1# crane/self-propelled hatchway cover P26 hangs
To FR106, that is, hatchcover stop place is moved ,/self-propelled hatchway cover P25 block hoist superposition then will be hung by 1# crane
On hatch coaming, and lock, then successively D6, D5 and D12 are added to by wharf crane and hung/self-propelled hatchway cover P25 on, make
Loading Center is located at FR106, and 1# crane raising radius is 18m at this time；Suspender is hung, main hook, which slowly rises, rises to 5 meters of height, and by 5
The high position of rice is defined as position A；
B.1# crane main hook load luffing test: after step a, from position, A does luffing movement, reaches luffing movement
To maximum functional angle, it is then back to position A；

(g)；
(3) load test:
A.1# crane is once tested: hoist includes hanging/self-propelled hatchway cover P25 and two deck D 5；Utilize 1# crane
To hang/self-propelled hatchway cover P25 is hung at FR106, then two deck D5 are added to hang/self-propelled hatchway cover P25 on,
Loading Center is set to be located at FR106,1# crane raising radius is 18m at this time；
Hoist is hung, after boom rotates outboard to boom and beam upright position, boom position is defined as position C, with normal speed
Three raising, revolution, luffing movement joint operations are done, lifting altitude peaks, and angle of revolution control becomes C70 ° of position
Width requires to accomplish 9 meters and 33 meters of maximum working radius of minimum working radius, continues 15 minutes, finally incites somebody to action in initial position FR106
Hoist removes；
B.1# crane second trial: hoist includes hanging/self-propelled hatchway cover P25, hangs/self-propelled hatchway cover P26, diformazan
Plate D 5 and two deck D12；To be hung using 1# crane/self-propelled hatchway cover P26 is hung at FR106, then will hang/from
Line hatchway cover P25, two deck D5 and two deck D12 be added to hang/self-propelled hatchway cover P26 on, be located at Loading Center
FR106,1# crane raising radius is 18m at this time；Hoist is hung, three raising, revolution, luffing movement joints are done with normal speed
Operation, lifting altitude peak, 360 ° of angle of revolution, and luffing requires to accomplish 9 meters of minimum working radius and maximum functional half
33 meters of diameter, continues 15 minutes, finally remove hoist in FR106；
C.1# crane auxiliary hook raising is tested: by boom rotation direction harbour, boom is vertical with captain direction, and boom position is defined
For position D, hoist is lifted by crane with auxiliary hook, three raising, revolution, luffing movement joint operations are done with normal speed, lifting altitude reaches
To highest point, D70 ° of position, luffing requires to accomplish 9 meters of minimum working radius and maximum working radius 36.5 for angle of revolution control
Rice, continues 15 minutes, finally removes hoist in initial position FR106；
D. use 1# crane instead 2# crane, using 2# crane carry out load test, the test procedure repeat step (a)~
(c)；
(4) wheels-locked testing:
A. main hook loads a wheels-locked testing: in a in step (3), respectively in maximum working radius, maximum raising and maximum
It brakes when decrease speed, raising does 1 brake, and 3 brakes are done in decline, meanwhile, when maximum rotational speed, maximum luffing, is stopped
Only test；
B. main hook load secondary braking test: in the b in step (3), respectively in maximum working radius, maximum raising and decline
It brakes when speed, raising does 1 brake, and 3 brakes are done in decline, meanwhile, when maximum rotational speed, maximum luffing, carries out stopping examination
It tests；
C. use 1# crane instead 2# crane, using 2# crane carry out wheels-locked testing, the test procedure repeat step (a)~
(b)；
(5) safety feature test:
A. emergency stops test: starting pumping plant is answered at crane driver's cabin, main junction box, power unit, channel respectively
Anxious button cutting test, guarantees pumping plant can be made to stop working immediately in these position emergency switching-ofves；
B. emergency manual operation test: cutting off the power, raising of being decided respectively with manual pump, secondary raising, luffing and rotation；
C. emergency load discharges test: first testing main hook, starts pumping plant, stops after hoist is lifted by crane 0.5 meter, and pass through
It presses emergency and discharges button release hoist；Auxiliary hook is tested again, starts pumping plant, is stopped after hoist is lifted by crane 0.5 meter, and pass through
It presses emergency and discharges button release hoist；The hoist includes hanging/self-propelled hatchway cover P25, hangs/self-propelled hatchway cover
P26, two deck D5, two deck D6 and two deck D12；
(6) post-test-inspection: check that whether there is or not obvious deformation or damages for crane structure；The crane include 1# crane and
2# crane.
