detailed description

Specific embodiment 1: As shown in Figure 1-5, a quick braking device for a sheave according to the utility model includes a brake cylinder 1, a booster rod I2-1, a booster rod II2-2, and an adjustment bolt 3 , fixed rod 4, connection plate Ⅰ5-1, connection plate Ⅱ5-2, brake pad Ⅰ6-1, brake pad Ⅱ6-2, rope wheel 7, screw 8, pin shaft 9 and wear-resistant sleeve 10, the system The hydraulic cylinder 1 is composed of a cylinder body 11, a piston rod 13, a return spring 12, an output shaft 19, and a guide sleeve 14. The corresponding position of the moving oil cylinder 1 forms a rotational connection; the booster rod I2-1 and the booster rod II2-2 form a rotational connection with the corresponding position of the fixed rod 4 through a pin shaft and a wear-resistant sleeve; the booster rod I2-1 and The connecting plate I5-1 forms a rotational connection through a pin shaft and a wear-resistant sleeve; the booster rod II2-2 forms a rotational connection with the connecting plate II5-2 through a pin shaft and a wear-resistant sleeve; the connecting plate I5-1 is connected to the The moving plate I6-1 is fastened and connected by screws; the connecting disc II5-1 and the brake pad II6-2 are fastened and connected by screws; the distance between the three connecting holes of the booster rod 2 has a proportional relationship, and the adjusting bolt 3 Threaded connection with fixed rod 4 can fine-tune booster rod Ⅰ2-1, booster rod Ⅱ2-2 to rotate and correspondingly drive connecting disc Ⅰ5-1, connecting disc Ⅱ5-2 to move in opposite directions, adjust brake pad Ⅰ6-1, brake pad II6-2 The initial distance to the rope pulley 7, the cylinder body 11 and the piston rod 13 of the brake cylinder 1 are all floating type, the output shaft 19 is connected with the cylinder body 11 and the piston rod 13 through threads, and the system The return stroke of the hydraulic cylinder 1 is controlled by the return spring 12, and the positioning of the return spring 12 is determined by the piston rod 13 and the guide sleeve 14.
