The invention provides a hoisting device applied to automatic loading and unloading of an overhead high-voltage transmission line inspection robot. The hoisting device comprises a U-shaped support, nut lead-screw driving mechanisms and sliding blocks, wherein an opening of the U-shaped support faces downwards; two vertical bars are hollow, and vertical openings are opened in the inner side face and the outer side face (or one of the two side faces); the lower end of each vertical bar is connected with a horizontal platform which is bent inwards and extends, and the upper part of the outer side of each vertical bar is fixed with an upper hook which is bent downwards; in each nut lead-screw driving mechanism, a lead screw is respectively rotatably supported in the hollow vertical bar of the U-shaped support by an upper bearing and a lower bearing, the lower end of the lead screw is in key joint with a large gear, the large gear is meshed with a small gear pinion which is arranged on the output shaft of a motor, the motor can rotate positively and negatively and is fixed on the horizontal platform at the lower end of the vertical bar; each sliding block sleeves the exterior of the corresponding vertical bar of the U-shaped support and is fixedly connected with a nut of the corresponding nut lead-screw driving mechanism through the corresponding vertical opening, and a lower hook which is bent upwards is fixed on the outer side of the sliding block. The hoisting device provided by the invention can directly hoist the inspection robot, and realizes the automatic loading and unloading of the inspection robot; the operation is simple and convenient, and the hoisting device is safe and reliable.
