Detailed description of the invention
See Fig. 1 and 2, it is shown that the Multifunctional lifting mechanism of steel wire rope variable power of the present utility model.
The Multifunctional lifting mechanism of described steel wire rope variable power includes that trolley frame 4, described trolley frame 4 are provided with hoist engine 2 and the driving means driving hoist engine 2 to rotate, and described trolley frame 4 is additionally provided with fixed pulley group 3.
In order to realize variable steel wire rope multiplying power, described Multifunctional lifting mechanism also can be provided with the first running block 5 and the second running block 6, described trolley frame 4 is provided with the locking device 4 of dismountable fixing described first running block 5, described second running block 6 is detachably secured to suspender, and described suspender also can be provided with the fixing device of dismountable fixing described first running block.
Thus, trolley frame being installed hoist engine and fixed pulley group, the first running block can lock with trolley frame, become fixed block group, it is also possible to transfer and be connected with suspender, becomes running block and uses.Lifting by crane lighter object when, the first running block is locked with trolley frame, be only connected with suspender with the second running block, lifting by crane heavier object when, release the locking of the first running block, use two groups of running blocks to be connected work with suspender simultaneously.
The operation principle of the application be described below:
1, when the less lifting capacity of needs and fast speed, release the connection of the first running block and suspender, hoist engine works, and receives steel wire rope, and the first running block can rise, when the first running block rises to trolley frame upper locking device, first running block is locked by locking device, and the most only running block two is connected with suspender, and the multiplying power of steel wire rope reduces, lifting capacity reduces, and lifting velocity increases.
2, when needs relatively big elevating capacity and fast speed, release the locking of the first running block and trolley frame, then hoist engine work, transfers steel wire rope, and the first running block declines by deadweight, after the first running block drops to the position of suspender, being connected with suspender by first running block, the multiplying power of such steel wire rope is the multiplying power sum of two groups of assembly pulleys, and multiplying power increases, lifting capacity increases, and lifting velocity reduces.
Wherein, described driving means can comprise driving motor, and the output shaft of described driving motor can be connected to hoist engine 2 by shaft coupling.
Wherein, the movable pulley of described first running block 5 is more than the movable pulley of the second running block 6.
Wherein, hold lower edge to be provided with multipair travelling wheel before and after described trolley frame 1, move with traveling before and after providing trolley frame 1.
Wherein, described locking device 4 can be lock pin and the driving structure driving lock pin, and described first running block 5 is provided with the lockhole passed for lock pin or houses fixing locked groove for lock pin, thus realizes the auto lock of locking device 4.
Wherein, also can comprise the 3rd running block, described trolley frame 1 is provided with the locking device of dismountable fixing described 3rd running block.
Wherein, described locking device can be lock pin and the driving structure driving lock pin, and described 3rd running block is provided with the lockhole passed for lock pin or houses fixing locked groove for lock pin, thus realizes the auto lock of locking device.
As can be seen here, the utility model has the advantage of:
1, simple in construction, easy to use, with low cost；
2, realize two kinds or the conversion of above steel wire rope multiplying power, need not wiring again, be suitable for the most extensive.
It is readily apparent that above description and record are only to illustrate rather than in order to limit disclosure of the present utility model, apply or use.Although describing the most in an embodiment and being described in the drawings embodiment, but this utility model be not intended to by accompanying drawing example and be described as in an embodiment it is now recognized that optimal mode with implement teaching of the present utility model specific examples, scope of the present utility model will include any embodiment falling into description and appended claims above.
