Stay cable whole bundle intelligent tensioning equipment

Abstract

The invention discloses stay cable whole bundle intelligent tensioning equipment which comprises a front fixing plate, a rear fixing plate and an outer supporting frame and is characterized in that the front fixing plate and the rear fixing plate are supported and connected through the outer supporting frame, an inner fixing plate and an inner supporting frame are further arranged in the front fixing plate, the rear fixing plate and the outer supporting frame, the inner supporting frame is connected with the front fixing plate, the inner supporting frame supports and fixes the inner fixing plate, tensioning anchors are arranged in the inner fixing plate and the inner supporting frame, the rear ends of the tensioning anchors are fixedly connected with tensioning columns, second open holes are formed in the center of the inner fixing plate, the diameter of the second open holes is larger than that of the tensioning columns, movable base plates are arranged at the other ends of the tensioning columns, the tensioning columns penetrate through the second open holes to be fixedly connected with the movable base plates, four first jacks are arranged between the movable base plates and theinner fixing plate, and four second jacks are arranged between the movable base plates and the rear fixing plate. The stay cable whole bundle intelligent tensioning equipment has the beneficial effects of being consistent in tensioning strength and capable of preventing slipping.

Description

technical field [0001] The invention relates to the technical field of tensioning equipment, in particular to an intelligent tensioning equipment for whole bundles of cable stays. Background technique [0002] Cable-stayed cables are the main load-bearing components that directly transfer the weight of the main girder and deck of the cable-stayed bridge to the tower. The material of the stay cable is usually a steel wire rope, and the main form is different according to its composition method, especially when the multi-strand steel wire rope is installed and fixed, it needs to be completed with the help of equipment with the whole bundle tension condition. [0003] However, at present, the more common cable tensioning equipment is mostly single-strand steel wire tensioning equipment, which leads to a large amount of engineering work and cumbersome procedures for the installation of multi-strand steel wire ropes, and it is easy to cause tension between multi-strand steel wire...

Problems solved by technology

[0003] However, at present, the more common cable tensioning equipment is mostly single-strand steel wire tensioning equipment, which leads to a large amount of engineering work and cumbersome procedures for the installation of multi-strand steel wire ropes, and it is easy to cause tension between multi-strand steel wire ropes. Inconsistency, etc., and the equipment with multi-strand steel wire rope tension has the inconvenience of adjusting the tension stroke of the steel wire rope, which leads to the jack stroke unable to meet the tension force, resulting in secondary tension, and there is no protective measure during the tension process, which is easy Cause defects such as steel wire falling off. At the same time, due to the stretching of the steel wire rope during the stretching process, the crystal phase of the internal structure is stretched during the process of thinning and elongating the steel wire rope and has more contact with oxygen, resulting in accelerated corrosion. Therefore, it is necessary to design a kind of intelligent tensioning equipment for the whole bundle of cable stays with consistent tension force and anti-skid
