Description
Technical field
The invention belongs to technical field of ships, particularly to the abridged edition type lift heavy of a kind of heavy lift carrier
Test method.
Background technology
Along with the needs of marine cause development, operation on the sea is maximized increasingly, and marine large lifting equipment is required more by this
Come the highest.Rising on heavy lift carrier makes the manufacture requirements hung high, and difficulty is big, and wherein rising and making the hoisting test hung is of paramount importance one
Ring, the purpose of test is the inspection installation integrity of crane, correctness, functional reliability, and verifies whether performance indications accord with
Close design and test program requirement.Therefore rising and making the hoisting test hung is a comprehensive complicated engineering.Existing heavy lift carrier
Hoisting test method, be usually and from harbour, huge heavy weight be transported to ship, has then used to make and hung and join with huge heavy weight
Conjunction is tested, but this test method exists certain defect: in this test method, need to by huge heavy transporting heavy things to ship,
Carrying out hoisting test again, process is more complicated, meanwhile, need to use extraneous weight, can increase cost, and transport weight can strengthen labor
Fatigue resistance.
Therefore, a kind of cost, labor intensity and easily operated heavy lift carrier of can reducing is researched and developed
Abridged edition type hoisting test method is necessary.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can reduce cost, labor intensity

Hoist, turn round, three action joint operations of luffing, lifting altitude peaks, and angle of revolution controls in boom position
C70 °, luffing requires to accomplish the minimum radius of clean-up 9 meters and maximum working radius 33 meters, continues 15 minutes, finally at initial position
Lift heavy is removed by FR106；
B.1# crane second trial: lift heavy includes hanging/self-propelled hatchway cover P25, hangs/self-propelled hatchway cover P26, diformazan
Plate D 5 and two deck D12；1# crane is utilized to winch to, at FR106, then P25, D5 and D12 are added to by hatchway cover P26
On P26, making Loading Center be positioned at FR106, now the crane radius that hoists is 18m；Hang lift heavy, hoist with normal speed, return
Turn, three action joint operations of luffing, lifting altitude peaks, 360 °, angle of revolution, and luffing requires to accomplish minimum work
Radius 9 meters and maximum working radius 33 meters, continue 15 minutes, finally removed by lift heavy at initial position FR106；
C.1# crane auxiliary hook hoists test: by arm rotation direction harbour, arm is vertical with captain direction, and boom position is defined
For position D, lifting by crane lift heavy with auxiliary hook, hoist with normal speed, turn round, three action joint operations of luffing, lifting altitude reaches
To peak, angle of revolution controls in boom position D70 °, and luffing requires to accomplish the minimum radius of clean-up 9 meters and maximum working radius
36.5 meters, continue 15 minutes, finally at initial position FR106, lift heavy is removed；
D. 1# crane is used instead 2# crane, uses 2# crane to carry out load test, the test procedure repeat step (a)～
(c)；
(4) wheels-locked testing:
A. wheels-locked testing of main hook load: in a in step (3), hoist in maximum working radius, maximum and decline respectively
Brake during speed, hoist and do 1 brake, decline and do 3 brakes, meanwhile, carry out stopping examination when maximum speed of gyration, maximum luffing
Test；
B. main hook load secondary braking test: in b in step (3), hoist in maximum working radius, maximum and decline respectively
Brake during speed, hoist and do 1 brake, decline and do 3 brakes, meanwhile, carry out stopping examination when maximum speed of gyration, maximum luffing
Test；
C. 1# crane is used instead 2# crane, uses 2# crane to carry out wheels-locked testing, the test procedure repeat step (a)～
(b)；
(5) safety feature test:
A. emergent stopping is tested: start pumping plant, and carrying out at crane driver's cabin, main junction box, power unit, passage respectively should
Anxious button cuts off test, it is ensured that pumping plant can be made to quit work immediately in these position emergency switching-ofves；
B. manual operation of meeting an urgent need is tested: cut off the electricity supply, decide respectively with manual pump hoist, pair hoists, luffing and rotation；
C. load of meeting an urgent need discharges test: first tested by main hook, starts pumping plant, stops, and pass through after lift heavy is lifted by crane 0.5 meter
Pressing and emergent discharging button and discharge lift heavy；Again auxiliary hook is tested, start pumping plant, stop after lift heavy is lifted by crane 0.5 meter, and pass through
Pressing and emergent discharging button and discharge lift heavy；
(6) post-test-inspection: check that crane structure with or without substantially deformation or is damaged.
