Product introduction:
Intelligent tensioning:
Intelligent tensioning means not relying on manual control of workers, but using computer intelligent control technology, through the automatic operation of the instrument to complete the tensioning of steel strands.
The intelligent tensioning system is easy to operate, user-friendly, and suitable for all kinds of construction site environment. With the help of intelligent tensioning system, can automatically read the beam parameters, intelligent calculation of stretching process pressure, oil pump and wireless control, real-time wireless data acquisition and oil displacement information, automatic tensioning record function.
The whole without manual intervention, and with error correction, data synchronization, Zhang Lashen nuclear tension process control, the core is in the prestressed tension based control and summarize the construction technology, to control the tensioning process through the computer, completely changed the traditional manual manipulation by pump tensioning operation, realize the synchronization control of tension.
Because of the high precision and stability of the intelligent system, the intelligent tensioning technology can completely eliminate the interference of human factors and effectively ensure the construction quality of prestressed tensioning. It is the most advanced technology in the field of prestressed tension at home.
High frequency vibrator:
The high frequency vibrator depends on the frequency modulation power source to modulate the motor frequency to the high speed rotation, and drives the eccentric wheel to make the circle movement, thus produces the vibration, and passes the vibration through the raceway to the end cover and even the shell. Mainly used in high-speed railway construction, highway construction, track slab factory and bridge factory.
Characteristic:
Shaped GPG series high frequency vibrator has the advantages of long service life, high efficiency, large amplitude, strong vibration force, no vibration phenomenon, compact structure, convenient operation, few wearing parts and convenient maintenance.
High frequency power cabinet

Intelligent tensioning system
Intelligent prestress tensioning system, through the computer software to achieve control of prestressed Laquan process automation, to eliminate the interference of human factors, can effectively ensure the prestressing construction quality, prestressing technique domestically most advanced areas.
Working principle：
The intelligent tensioning system consists of three parts, the main engine, the oil pump and the jack. The stress of prestressed intelligent tension system is taken as the control index, and the elongation error is used as the proof index. System acquisition each tensioning equipment through the sensor technology (Jack) working pressure and elongation of steel strand (including shrinkage) data, and real-time data transmission to the host system to analyze and judge, at the same time stretching equipment (pump) receiving system commands, real-time adjustment of motor parameters, in order to achieve high precision the real-time control of pump motor speed, realize the real-time control of tension and loading speed. According to the preset program, the system sends instructions from the host computer, synchronously controls each mechanical action of each device, and automatically
completes the whole stretching process.
Main functions and features
Apply stress accurately
The intelligent tensioning system can precisely control the prestress value applied during construction, and reduce the error range from 15% to 1% of the traditional tension, (7. 12. 2) the second paragraph of the technical code for construction of highway bridges and culverts stipulates that the accuracy of tension control stress shall be + %
check the amount of elongation in time and realize z/double control"”
The system sensor collects the steel strand data in real time, feed back to the computer, calculate the elongation automatically, check whether the elongation error is within + 6% or not, and realize the z/double control" of stress and elongation”, (paragraph of the technical specification for highway bridge and culvert construction stipulates that the prestressing force should be checked with elongation when tensioning method is adopted. . . . The deviation shall be controlled at + 6%
3 、 symmetrical synchronous stretching
A computer controls two or more jacks simultaneously and synchronously symmetrically tensioning to realize the multiple top synchronous tensioning process, () the first paragraph of the technical code for construction of highway bridges and culverts stipulates that the allowable error of synchronous tensile force between the jacks is 2%
standardize tension process to reduce the loss of prestress
The tension intelligent control program, it is not affected by human and environmental factors: pause, loading rate, loading time and stretching process elements completely conforms to the bridge design and construction technical specification requirements, avoid or greatly reduce prestressing loss in the process of. (7. 12. 2) the second paragraph of the technical code for construction of highway bridges and culverts stipulates that "ensure that the jack has enough load time (5 minutes)"
automatically generate reports, eliminate data fraud
Automatic generation of tension record table, to eliminate the possibility of artificial fraud,
Real construction process can be restored. At the same time, the calculation and filling process of the data such as tensile force and elongation are omitted, and the work efficiency is improved.
6 、 remote monitoring function
Realize remote monitoring function, facilitate quality management and improve management efficiency. The unity of the owners, supervision, construction and inspection unit on the same Internet platform, can interact in real time, breaking the geographical constraints, to grasp the precast beams and bridge prestressed construction quality, to achieve real-time tracking, intelligent control, timely correction”.
