Accompanying drawing explanation
The electric power lifting that Fig. 1 provides for the utility model is from the structural representation of stop fixed pulley.
Detailed description of the invention
Below in conjunction with accompanying drawing, the electric power lifting that the utility model proposes is described further from stop fixed pulley.
As shown in Figure 1, electric power lifting is from the structural representation of stop fixed pulley.The lifting of this electric power comprises the pulley yoke 2 with hook 1 from stop fixed pulley, pulley yoke 2 is provided with the pulley 4 with groove 3, the side of pulley yoke 2 is provided with inverse u shape bracing frame 5, bracing frame 5 comprises upper plate 51 and two side shields 52, the lower end of bracing frame 5 and the lower end of pulley yoke 2 are fixed and intersect certain angle with pulley yoke 2, the upper plate 51 of bracing frame 5 is provided with through hole 53, expansion link 6 is provided with in through hole 53, the lower end of expansion link 6 is provided with wheel fork 7, be provided with to compress between wheel fork 7 upper end and upper plate 51 of expansion link 6 and push up spring 8, wheel fork 7 is provided with the brake wheel 10 with axis 9, brake wheel 10 inserts in the groove 3 of pulley 4, the side shield 52 of bracing frame 5 is provided with along side shield direction, there is the groove 54 of one fixed width, axis 9 two ends are positioned at groove 54, at side shield 53, pulley yoke 2 side and axis 9 correspondence position are provided with annulus 11, in annulus 11, are installed with the spacing stay cord 12 that end is fixedly connected with axis 9.During use, one end is fastened the free end of the rope of article from passing pulley 4 away from bracing frame 5 side and being placed in groove 3, axis 9 is positioned at the side of groove away from pulley yoke 5, upwards top pressure compression top spring 8, rope is pressed between brake wheel 10 and pulley 4, and the free end of rope is delivered to ground; Pull down the free end of rope, under the effect of rope friction force and compression top spring, axis 9 is positioned at the side of groove away from pulley yoke 5, and article rise along with rope; When article arrive assigned address, stop pulling down rope, come up rope, rope slides along pulley to reversing sense under the gravity of article drives, now, under the effect of friction force, rope drives axis 9 to move from the side of groove away from pulley yoke 5 to pulley yoke 5 side, axis 9 is in the process of movement, and owing to pressing by the top of pulley 4, expansion link 6 moves along on through hole 53, compression top spring, along with the top compressive strain of compression top spring 8, the increasing pressure between brake wheel and rope is large, until rope stops mobile; After construction completes, pull spacing stay cord, axis is made to get back to groove away from pulley yoke side, the pressure of brake wheel and rope reduces greatly, and its friction force also decreases, under the effect of article gravity, article drive rope to get back to ground, use convenient, and personnel take few, human cost reduces greatly; When article are lifted beyond assigned address, pull spacing stay cord, axis is made to get back to groove away from pulley yoke side, the pressure of brake wheel and rope reduces greatly, and its friction force also decreases, under the effect of article gravity, article drive rope automatically to fall to assigned address, then spacing stay cord is unclamped, and the rope that comes up, use convenient.
