cable path adaptive mechanism

Abstract

The invention relates to a cable diameter self-adaptation mechanism. The cable diameter self-adaptation mechanism comprises an axle. A driven wheel is arranged at the middle portion of the axle. Connecting blocks are fixedly arranged on the two sides of the driven wheel through the axle. One side of each connecting block is fixedly provided with a sliding rod. Each sliding rod is sleeved with an elastic piece. First limiting pieces are fixedly arranged at the two ends of the axle. The driven wheel is located in a device box, and space for a stay cable to penetrate is formed between the driven wheel and a drive wheel. Sliding grooves are formed in the two opposite side faces of the box, and the two ends of the axle penetrate the sliding grooves and are clamped in the sliding grooves. The first limiting pieces are located outside the box, the diameter of the first limiting pieces is larger than that of the sliding grooves, and the first limiting pieces are closely attached to the outer wall of the box. The connecting blocks are located in the box. One end of each elastic piece abuts against the corresponding connecting block, and the other end of each elastic piece abuts against the inner wall of the box. The box is provided with through holes for the sliding rods to penetrate. According to the cable diameter self-adaptation mechanism, the driven wheel can tightly press the stay cable through elastic force of the spring, the purpose that the mechanism elastically adapts to the cable diameter is finally achieved, stable work of the device is guaranteed, and the cable force detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a cable diameter adaptive mechanism in a cable-stayed climbing device. Background technique [0002] The cable-stayed bridge is an important type of bridge. The cable-stayed cable is one of its main stress components. Its working state is the decisive factor for the safe operation of the cable-stayed bridge. Therefore, it is necessary to The internal force of the cable is measured to ensure that the stay cable is in a normal stress state. [0003] At present, in engineering applications, there have been devices that can automatically climb and detect the cable force, such as the cable climbing device mentioned in the Chinese Patent Publication No. CN205741908U, but these devices cannot adapt well to the cable path during the climbing process. Changes lead to instability in the climbing process, and for stay cables with completely different cable diameters, the device cann...
