The invention belongs to the technical field of construction engineering, and particularly relates to a bridge prestressing force intelligent tensioning system. The system comprises an oil source storage device, an electronic control system and a lifting jack, the oiling channel of the oil source storage device is connected with the lifting jack through an oil pipeline, the oil source storage device comprises a device housing and an oil tank installed at the bottom of the inner cavity of the device housing, a motor is installed on the left side of the top of the oil tank, the bottom of the output end of the motor is connected with a coupling, the bottom of the coupling is connected with the power input end of an oil pump, and a coarse filter is connected with the input end of the oil pumpthrough a pipeline. According to the system, tensioning procedures are controlled by the intelligent system to achieve the control of the operations of multiple lifting jacks and 'multiple lifting jack synchronous construction' to improve the quality of an engineering project; the stretching amount of steel tendons is accurately controlled and measured. By automatically measuring the stretching amount of steel strands through a warning system, synchronous loading speed of prestressing tensioning force is accurately controlled, and the error caused by time difference of tensioning force can beeffectively reduced.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a bridge prestressed intelligent tensioning system. Background technique [0002] Prestressed tensioning is one of the key links in the construction of prestressed bridges. The quality of tensioning directly determines the service life and operational safety of bridges. At present, the tensioning construction method of the prestressed steel beam generally adopts the method of manually operating the electric oil pump to drive the jack. During this process, the equipment is controlled manually, the tension is controlled by visually checking the readings of the mechanical pressure gauge, the elongation of the piston of the jack is manually measured, and the elongation of the prestressed steel beam is manually calculated to achieve the dual control goal of prestressed tension. The traditional prestressed tensioning process has poor measurement and control accuracy, ...
