Detailed description of the invention
Illustrate selected embodiment of the present invention referring now to Figure of description, the following explanation of embodiments of the invention is only exemplary, the scheme be not meant to limit the present invention.
With reference to figure 1,2, a kind of crane hoisting becomes multiplying factor device automatically, comprises fixed pulley 1, zoom rate pulley 6, running block 7, drop in beam 2 and fixed axis 8; Fixed axis 8 is arranged on crane, fixed axis 8 is installed fixed pulley 1 and Wirerope fixing device 9; Drop in beam 2 one end is hinged on fixed axis 8, and drop in beam 2 other end is provided with hanging scroll 3; Zoom rate pulley 6 is arranged on pulley spindle 13, and pulley spindle 13 is positioned at below hanging scroll 3, pulley spindle 13 is connected with link plate 4, and this link plate 4 can mount with hanging scroll 3 and be integrated; Running block 7 is arranged in movable pulley rack 14 by movable pulley axle 15, and movable pulley axle 15 is positioned at below pulley spindle, and running block comprises the first movable pulley 10 and the second movable pulley 11; Fixed pulley, the first movable pulley, zoom rate pulley and the second movable pulley are wound around successively by steel wire rope 16.
In the present embodiment, link plate 4 is provided with the pocket for the punch head 401 that can hold hanging scroll 3, and link plate 4 is provided with block 403, pocket for the punch head 401 is semicircular structure, when drop in beam 2 rotates around fixed axis 8 time, can meet the swing requirement that hanging scroll 3 is linked into or throws off link plate 4.
In the present embodiment, link plate 4 is outwards provided with downward-sloping extended surface 402 along pocket for the punch head 401 side, baffle plate 5 upper end is the inclined plane 501 being tilted to lower setting, and inclined plane 501 and extended surface 402 play the guiding role when hanging scroll 3 is linked into or throws off.
In the present embodiment, link plate 4 is connected with baffle plate 5 by a rotating shaft, baffle plate 5 center of gravity is positioned at the left side of center of rotation, baffle plate 5 lower-left end is connected with balancing weight 12, and baffle plate 5 can rotate around the axis under gravity, under balancing weight 12 acts on, spacing by the block 403 of link plate 4, baffle plate 5 can stop in the position shown in the figure 1, namely closes door state, can prevent hanging scroll 3 from throwing off.
In practice, link plate 4 is two, is separately positioned on the two ends of pulley spindle 13.
As shown in Fig. 3 a-1 to Fig. 3 d-2, when two multiplying powers become four multiplying powers, suspension hook rises, and hanging scroll 3 contacts inclined plane 501 and descending along inclined plane 501, until bump against baffle plate 5, and makes hanging scroll 3 slightly lower than the pocket for the punch head 401 of link plate 4.Suspension hook slowly rises, and under gravity, hanging scroll 3 will enter in the pocket for the punch head 401 of link plate 4 slowly, and drop in beam 2 is combined with zoom rate pulley 6, and operation suspension hook declines, and zoom rate pulley 6 is separated with running block 7, completes the process that two multiplying powers become four multiplying powers.
As shown in Figure 4 a-1 to 4 d-2, when four multiplying powers become two multiplying powers, operation suspension hook rises, until zoom rate pulley 6 enters running block 7 and is combined as a whole, suspension hook slowly rises, hanging scroll 3 contacts extended surface 402 and descending along extended surface 402, press against baffle plate 5 to rotate clockwise simultaneously, until baffle plate 5 is separated with hanging scroll 3 and return under gravity, operation suspension hook declines, and hanging scroll 3 is separated with zoom rate pulley 6, because baffle plate 5 is closed the door, therefore hanging scroll 3 can not reenter pocket for the punch head 401 under gravity, complete four multiplying powers and become two multiplying power processes.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
