Problems solved by technology
The hoist used in this method must have a large pulling tonnage and a large rope capacity, resulting in a large weight (about 5 tons) and a large volume of the hoist. Turning and other operations have brought great difficulty
Preparatory work for beam traction requires more manpower, material resources and time, which is not conducive to improving construction efficiency and construction economy

The invention discloses a full-automatic hydraulic steel strand traction machine. The full-automatic hydraulic steel strand traction machine comprises an intelligent pump station system and a jack. The jack is connected to the intelligent pump station system through a hydraulic oil pipe; the jack is provided with a second lead channel in the axis direction. the jack comprises a fixed rod and a piston rod; a first support is arranged between the jack and a segmental beam body; a second support is nested and fixedly arranged at one end, far away from the first support, of the fixed rod; a firstautomatic anchorage device is fixedly arranged at the end part of the piston rod; a second automatic anchorage device is arranged on the side, away from the jack, of the second support; a steel strandlead is arranged on the axes of the first lead channel, the second lead channel, the first automatic anchorage device and the second automatic anchorage device in a penetrating manner; and a steel strand connector is fixedly arranged at the end part, close to the segmental beam body, of the steel strand lead. The traction force is large, the self-weight is light, the size is small, and the automation degree is high.
Description
technical field [0001] The present disclosure generally relates to the technical field of building construction equipment, and in particular to a fully automatic hydraulic steel strand tractor. Background technique [0002] With the progress of road and bridge engineering technology at home and abroad, segmental beam assembly technology has become the mainstream in bridge design and construction. According to the structural characteristics of segmental assembled bridges, the segmental girders are placed on the bridge erecting machine or temporary supports, adjusted and installed in place according to the linear monitoring data, temporarily stretched, and then permanently prestressed steel strands are stretched, and the self-weight of the segmental girders The system is transferred to the pier, and the main body of the bridge is installed. [0003] The tensioning construction of permanent prestressed steel strands is the last link in the installation of the main body of the ...
