On east side operation platform.There is tower height indicator light on operation console：101HL-103HL.
The course of work of the crane hoisting of the utility model and cocked mechanism switching control protective device is：
1st, operation sequence during main raising：
The changing-over gear 9 of main hoisting mechanism is switched on main hoisting drum 4, switching switch 102LK, which is switched to, has led raise-position
Put.Travel switch QBK2, QBK4, QBK6 is connected with 102LK (5-6) at this time, and master controller 101LK is in " 0 " position, system zero
Position, performs startup and prepares.
Operate 1-5 grades of the rising of 101LK or decline the 1-5 grades of raisings for carrying out main hoisting mechanism or step-down operation.
2nd, operation sequence when cocked：
The changing-over gear 9 of main hoisting mechanism is switched on cocked reel 3 first, switching switch 102LK is switched to cocked position.
Travel switch QBK1, QBK3, QBK5 is connected with 102LK contacts (1-2) at this time, and master controller 101LK is in " 0 " file location, PLC
Cocked zero-bit is connected, startup is performed and prepares.
A, the cocked operation of pylon：Cocked operation operates the rising of 101LK as the raising operation sequence of main hoisting mechanism
1-5 grades carry out cocked operation.
In operation, after pylon 6 is in place, spacing 1QCK, 2QCK action in place of cocked frame 1, cuts off positive contactor,
Cocked end.After need to mount cocked frame 1 and cocked frame strut 2, cut off cocked circuit, connect main hoisting circuit.
During cocked, due to the cocked action of pylon 6 so that the angle of pylon 6 constantly increases, and makes the pylon of root high
Spend spacing 13-15 to act successively, be followed successively by pylon 22.5 meters of positions spacing 13 (301XK), 25 meters of positions of pylon spacing 14
(302XK) and pylon 45.5 meters of positions spacing 15 (303XK).Tower height is spacing to be used as height instruction.
B, pylon lowering operation：Lowering operation is as the step-down operation program of main hoisting mechanism.Pylon stopped after falling
Reverse contactor circuit, operation terminate.
3rd, cocked and main raising conversion operation：
When cocked and main raising is changed each other, it is necessary to operate changing-over gear, have to declutch before operating changing-over gear.Declutch
Operation is to declutch on manual operation joint action table by lower button QA, QB, brake.Then changing-over gear is operated to complete cocked and lead
The conversion operation risen, when changing-over is to cocked position, QBK1, QBK3, QBK5 action, can carry out cocked operation.Changing-over is to raising
During position, QBK2, QBK4, QBK6 action, can carry out lift operations.
Above example is implemented under premised on technical solutions of the utility model, gives detailed embodiment
With specific operating process, but the scope of protection of the utility model is not limited to the above embodiments.Side used in above-described embodiment
Method is conventional method unless otherwise instructed.
