The displacement sensor installation assembly comprises a linear displacement sensor, a connection piece, an outer shell and a protective sleeve in the outer shell. The linear displacement sensor is arranged in the protective sleeve in a penetrating mode, the fixing end of the linear displacement sensor is fixedly installed at one end of the outer shell, the movable end of the linear displacement sensor is connected to one end of the protective sleeve, the protective sleeve moves between the outer shell and the linear displacement sensor in a sliding mode, a linear limit groove is axially formed in the outer wall of the protective sleeve, and a limit pin matched with the linear limit groove is installed on the outer shell and is used for preventing the protective sleeve from rotating. The displacement sensor installation assembly is compact in structure and easy to install and use and maintain, can improve measurement precision of the displacement sensor, reduces measurement errors, and meanwhile can greatly prolong service life of the displacement sensor.
Description
Technical field
The utility model relates to the installation component in the intelligent tensioning system, is specifically related to the displacement transducer installation component in a kind of intelligent tensioning system.
Background technology
In bridge road construction of today, pre-stress construction is widely used, wherein critical process---stretch-draw, the quality of its construction quality, can directly affect the durability of structure, but traditional stretching construction is pure by by rule of thumb manual operation of constructor, error rate is very high, can't guarantee the pre-stress construction quality.Many bridges are forced to reinforce in advance because pre-stress construction is defective, and are serious even collapse suddenly, caused huge life and property loss to society.Intelligent tensioning refers to not rely on the workman manually to control, and utilizes the control with computational intelligence technology, by the instrument automatic operation, finishes the stretching construction of steel strand.The intelligent tensioning technology is effectively guaranteed the tensioning construction quality because high accuracy and the stability of intelligence system can be got rid of interference from human factor fully, is the state-of-the-art technique in present domestic prestressed stretch-draw field.
The intelligent tensioning system is comprised of system host, oil pump, stretch-draw jack three parts.Prestressing force intelligent tensioning system is take stress as the control index, and the elongation error is as the check and correction index; System gathers the operating pressure of every stretch-draw jack and the data such as elongation (containing amount of recovery) of steel strand via pressure sensor and displacement transducer, and transfer data in real time system host and analyze judgement, the instruction of simultaneous tension equipment (pumping plant) receiving system, adjust in real time the variable-frequency motor running parameter, thereby realize the rotating speed of high accuracy real-time monitoring Oil pump electrical machinery, realize the in real time accurately control of stretching force and loading velocity.The displacement transducer of existing intelligent tensioning system mostly is to be directly fixed on the stretch-draw jack, and then in addition the spacing slide-bar that parallels with it is set, and the two keeps and stretch-draw jack movable end synchronous shift by subtriangular vertical connector; Yet this of displacement transducer kind of mounting means easily produces torsional forces, and then produces deformation, not only causes the error of measurement, goes back easy fitted displacement sensor injury, greatly shortens its application life.
Summary of the invention
