Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The invention provides a kind of assembly pulley rapid fixing, comprise top braces and switching device 1, fixed pulley 2.
Figure 2 shows that top braces of the present invention and switching device structure schematic diagram.
Described top braces and switching device 1 comprise bracing frame 1-1, opening-closing plate 1-3, double hook plate 1-2 and anchor shaft 1-5, lock shaft 1-4 and locking pin 1-7, play the function to the support of whole equipment and the fixing of fixed pulley 2.
Support frame as described above 1-1 is connected on the jib of elevator machinery, supports whole lifting appliance.
Anchor shaft 1-5 is used for connecting and fixing each group of double hook plate 1-2.
Fig. 3 is of the present invention pair of plate hook and opening-closing plate unitized construction schematic diagram.
Described double hook plate 1-2 is buckle structure, two double hook plate 1-2 are mounted opposite, a fixed pulley unit is fixed after the two plate hook 1-2 of two pieces interlocks, the "eight" shape guide groove that the double hook plate 1-2 of make-up is formed can make up fixed pulley 2 by reversing the deviation produced, make fixed pulley 2 easily fix by double hook plate 1-2.
Described opening-closing plate 1-3 is welded on the top of double hook plate 1-2, and be provided with two groups of locking axis holes, adopt lock shaft 1-4 to fix, playing the effect of locking, is safety guard.
Relative two double hook plate 1-2 and bracing frame 1-1 are installed together by anchor shaft 1-5.
Locking pin 1-7 is spring cotter or Type B pin, is provided with anticreep pin-and-hole, is arranged on lock shaft 1-4, has the effect of multiple anticreep.
Fig. 4 is fixed pulley structural representation of the present invention.
Described fixed pulley 2 comprises fixed pulley 2-1, fixed pulley frame 2-2, fixed pulley axis 2-3 and bearing pin 2-4.
Described fixed pulley frame 2-2 is two panels symmetric panel, and fixed pulley 2-1 is fixed on fixed pulley frame 2-2 by fixed pulley axis 2-3.
Bearing pin 2-4 is arranged on the top of fixed pulley frame 2-2, be used for connecting fixed pulley 2 and double hook plate 1-2, be fixed on fixed pulley frame 2-2 by only axillare, the combination of described top braces and switching device 1 and fixed pulley 2 or to be separated be that folding by bearing pin 2-4 and double hook plate 1-2 realizes.
