Abstract

The invention discloses a foldable circular-arc-shaped supporting device. Inner telescopic shafts and outer telescopic shafts are connected in a sliding mode, the outer ends of the inner telescopic shafts are connected with left supporting shafts in a rotating mode, and the outer ends of the outer telescopic shafts are connected with right supporting shafts in a rotating mode. Sleeves are arranged on the outer telescopic shafts in a sleeved mode, and front top plates and first sleeves are fixedly connected. The two ends of each connecting rope penetrate through front top plate rope holes and rear top plate rope holes respectively, and connecting convex plates and connecting concave grooves are matched. A plurality of supporting modules are sequentially arranged from front to rear in an arc shape, and a cross is arranged between every two adjacent supporting modules. The two ends of first upper cross bar frames, the two ends of second upper cross bars, the two ends of first lower cross bars and the two ends of second lower cross bars are connected with the corresponding left supporting shafts and the corresponding right supporting shafts respectively in a rotating mode. Two bases are arranged on the front portions and the rear portions of the supporting modules respectively. The lower ends of the left supporting shafts on the front portion and the rear portion are fixedly connected with corresponding second base pillars respectively, and the lower ends of the right supporting shafts on the front portion and the rear portion are fixedly connected with corresponding first base pillars respectively. The foldable circular-arc-shaped supporting device is used for supporting other components in an annular cavity.

Description

technical field [0001] The invention relates to a supporting device, in particular to a foldable arc-shaped supporting device. Background technique [0002] The support device is a device built inside or outside the equipment, and its function is to provide passage and support for other equipment or people. For example, the annular support guide rail constructed in the annular cavity of the tokmak device, or the passage of maintenance and staff in huge equipment, all need a support device that is convenient to construct and has strong structural adaptability. Most of the existing support guide rail technologies are monolithic structures, which are not conducive to construction and have poor adaptability. Contents of the invention [0003] The present invention provides a foldable arc-shaped supporting device in order to solve the problems that the existing supporting guide rail is an integral structure, which is unfavorable for construction and not strong in adaptability....
