Embodiment Construction
[0015] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] Depend on Figure 1 to Figure 5 Given, the present invention includes a walking beam 1, an electric hoist 2 is provided on the walking beam 1, a mounting plate 3 is provided in the middle of the electric hoist 2, a first collision groove 4 and a second collision groove 5 are provided on both ends of the mounting plate 3, The depth of the first collision groove 4 is smaller than that of the second collision groove 5. The two ends of the walking beam 1 are provided with the first transmission shaft 6 and the buffer shaft 7 which are aligned with the first collision groove 4 and the second collision groove 5. The first collision The diameters of the groove 4 and the second collision groove 5 are respectively larger than the diameters of the first transmission shaft 6 and the buffer shaft 7, and the end of the first t...

The invention relates to an anti-impact device of an electric hoist and effectively solves a problem that the electric hoist is liable to damage. In the technical scheme, the electric hoist includes a travel beam, the electric hoist arranged thereon. A first transmission shaft and a buffer shaft are respectively arranged on two ends of the travel beam. A second transmission shaft is arranged at one side of the first transmission shaft. The first transmission shaft is connected to the second transmission shaft through a sliding plate. A second spring is connected to the left side of the sliding plate. A third spring is connected to the right side of the sliding plate. A rotatable clamp board is arranged above the second transmission shaft. The end of the clamp board is an arc-shaped surface. A gap is formed in the middle lower end of the clamp board, so that a structure that the gap can clamps a pressing ring, the upper end of the sliding plate can pushes the clamp board up to rotate the clamp board and the gap is separated from the pressing ring is formed. A start motor is arranged at the right side of the second transmission shaft and is provided with a button switch which is corresponding to the pressing ring. The button switch is non-contacted with the second transmission shaft. A swinging apparatus is connected to the start motor. The anti-impact device avoids damage on the electric hoist and also reminds a worker.
Description
technical field [0001] The invention relates to the technical field of crane lifting, in particular to an anti-collision device for an electric hoist. Background technique [0002] Electric hoist, referred to as electric hoist, is a light and small lifting equipment. Electric hoist has the characteristics of small size, light weight, and simple operation. It is easy to operate and easy to use. It is used in industrial and mining enterprises, storage terminals and other places. The lifting capacity is generally 0.1-80 tons, and the lifting height is 3-30 meters. It consists of a motor, a transmission mechanism and a reel or sprocket, and is divided into a wire rope electric hoist and a chain electric hoist. [0003] Electric hoists include wire rope electric hoists and chain electric hoists. As for the wire rope electric hoist, the electric hoist is a lifting device that combines lifting and walking, and the lifting part is composed of three parts. The conical rotor motor ...
