The specific embodiment
Illustrate selected embodiment of the present invention referring now to Figure of description, the following explanation of embodiments of the invention only is exemplary, the scheme that is not meant to limit the present invention.
With reference to figure 1,2, a kind of crane hoisting becomes the multiplying power device automatically, comprises fixed pulley 1, becomes multiplying power pulley 6, running block 7, drop in beam 2 and anchor shaft 8; Anchor shaft 8 is arranged on the hoisting crane, and fixed pulley 1 and steel rope fixer 9 are installed on the anchor shaft 8; Drop in beam 2 one ends are hinged on the anchor shaft 8, and drop in beam 2 other ends are provided with hanging scroll 3; Become multiplying power pulley 6 and be installed on the sheave shaft 13, sheave shaft 13 is positioned at hanging scroll 3 belows, is connected with link plate 4 on the sheave shaft 13, and this link plate 4 can articulate with hanging scroll 3 and be one; Running block 7 is installed on the movable pulley frame 14 by movable pulley axle 15, and movable pulley axle 15 is positioned at sheave shaft below, and running block comprises first movable pulley 10 and second movable pulley 11; Fixed pulley, first movable pulley, change multiplying power pulley and second movable pulley twine successively by steel 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, and pocket for the punch head 401 is semicircular structure, when drop in beam 2 when anchor shaft 8 rotates, can satisfy the swing requirement that link plate 4 was hung or thrown off to hanging scroll 3.
In the present embodiment, outwards be provided with downward-sloping extended surface 402 along pocket for the punch head 401 sides on the link plate 4, baffle plate 5 upper ends are to be tilted to down the dip plane 501 that arranges, and dip plane 501 and extended surface 402 play the guiding role when hanging scroll 3 is hung or thrown off.
In the present embodiment, be connected with baffle plate 5 by a rotating shaft on the link plate 4, baffle plate 5 centers of gravity are positioned at the left side of center of turn, baffle plate 5 lower-left ends are connected with clump weight 12, can rotate around the axis at gravity effect lower baffle plate 5, under clump weight 12 effects, block 403 by link plate 4 spacing, baffle plate 5 can stop in the position shown in the figure 1, and the state of namely closing the door can prevent hanging scroll 3 disengagements.
To shown in Fig. 3 d-2, when two multiplying powers became four multiplying powers, suspension hook rose as Fig. 3 a-1, and hanging scroll 3 contact dip plane 501 are also 501 descending along the dip plane, up to bumping against baffle plate 5, and made hanging scroll 3 be lower than the pocket for the punch head 401 of link plate 4 slightly.Suspension hook slowly rises, and under the gravity effect, hanging scroll 3 will enter in the pocket for the punch head 401 of link plate 4 slowly, drop in beam 2 and 6 combinations of change multiplying power pulley, and the operation suspension hook descends, and change multiplying power pulley 6 is separated with running block 7, finishes the process that two multiplying powers become four multiplying powers.
As Fig. 4 a-1 to shown in Fig. 4 d-2, when four multiplying powers become two multiplying powers, the operation suspension hook rises, enter running block 7 and be combined as a whole up to becoming multiplying power pulley 6, suspension hook slowly rises, hanging scroll 3 contact extended surfaces 402 and descending along extended surface 402, pressing baffle plate 5 to clockwise rotate simultaneously, separate and return under the gravity effect with hanging scroll 3 up to baffle plate 5, the operation suspension hook descends, and hanging scroll 3 separates with change multiplying power pulley 6, because baffle plate 5 has been closed the door, so hanging scroll 3 can not reenter pocket for the punch head 401 under the gravity effect, finish four multiplying powers and become two multiplying power processes.
Though above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be 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 modifications that creative work can make or distortion still in protection scope of the present invention.
