Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a braking device for electric block includes casing 1, and the left side of casing 1 is fixed with motor 2, and the inside of casing 1 rotates there is reel 3, is provided with braking component 4 on the output shaft of motor 2.
Wherein the braking component 4 comprises a sleeve 5 and a connecting plate 6, the sleeve 5 is fixed outside an output shaft of the motor 2, the left side inside the connecting plate 6 slides on the right side of the output shaft of the motor 2, the right side inside the connecting plate 6 slides on the left side of the winding drum 3, two ends of the right side of the sleeve 5 are hinged with connecting rods 7, the connecting rods 7 are arranged in an arc shape, the left side of the sleeve 5 is fixed with a fixed plate 8, the right side of the fixed plate 8 slides with a transmission rod 9, the transmission rod 9 and the connecting rods 7 are in a hinged state, the connecting plate 6 is internally provided with a sliding groove, the sliding groove is inclined at 60 degrees, two ends between the fixed plate 8 and the connecting plate 6 are both fixed with spring telescopic rods 10, the purpose of positioning the connecting plate 6 is achieved through the arrangement of the spring telescopic rods 10, the front surface of the transmission rod, thereby achieving the purpose of driving the transmission rod 9 to drive the connecting plate 6 to move, when the electric hoist is hoisted, the motor 2 rotates clockwise, the connecting rod 7 drives the transmission rod 9 to move towards the sleeve 5, meanwhile, the motor 2 drives the winding drum 3 to rotate through the connecting plate 6, when the hoisting is finished, the motor 2 rotates anticlockwise, the sleeve 5 rotates anticlockwise, the connecting rod 7 expands, thereby the transmission rod 9 moves towards each other, the connecting plate 6 moves leftwards by the sliding of the rotating rod 11 in the chute of the connecting plate 6, the clamping connection between the connecting plate 6 and the winding drum 3 is released, the motor 2 can not drive the winding drum 3 to work, the braking is finished, compared with the traditional clamping type braking device, the braking device brakes the motor 2, the load on the motor 2 is small, and the service life of the motor 2 is prolonged, the use cost of the electric hoist is indirectly reduced, and the practicability of the electric hoist is improved.
