Abstract

The invention discloses an intelligent prestressing force stretching system, and relates to the technical field of prestressed girder stretching equipment in engineering construction of railroads, roads, municipal bridges and the like. The intelligent prestressing force stretching system comprises an intelligent stretching lifting jack and stretching pump stations, wherein at least two stretching pump stations are provided; the stretching pump stations are respectively connected with an oil inlet and an oil return opening of the intelligent stretching lifting jack through high-pressure oil pipes; a data cable of a control system of the stretching pump station is connected with a displacement sensor of the intelligent stretching lifting jack; and electromagnetic proportioning valves are arranged on oil lines of valve bodies of the stretching pump stations. Compared with the prior art, the pump stations are variable capacity oil pumps, the variable quantity is small flow rate when the stretching control pressure intensity is approximated, the accuracy can be ensured effectively when the preset stretching pressure value, the control accuracy of the stretching control pressure intensity Mpa is less than or equals to 0.5 percent, the control accuracy of the stretching elongation value is less than or equals to 0.5 percent, both the stretching control pressure intensity Mpa and the stretching elongation value are controlled by a computer automatically and accurately, the result of the stretching elongation value is obtained through automatic calculation, and the error range is narrowed from the conventional stretching range value down to the range value ranging from minus or plus 1 percent, wherein, the conventional stretching range value ranges from minus or plus 15 percent.

Description

technical field [0001] The invention relates to the technical field of prestressed beam tensioning equipment in the construction of railways, highways, municipal bridges and other projects, in particular to a prestressed intelligent tensioning system. Background technique [0002] In the construction of prestressed engineering, the anchorage of all prestressed tendons requires tensioning equipment to apply prestress to the prestressed tendons. At present, traditional tensioning equipment uses manual methods to operate multiple handles of each control valve. Measuring the elongation value of the prestressed tendon and reading the pressure value of the pressure gauge, there are complicated operating procedures, large reading errors, slow measurement process, and the prestressed tension value is generally insufficient due to human factors, and the misoperation rate is high; A series of problems such as recording according to the actual tensioning results and untrue records will...
