Description
Technical field
This utility model relates to tube drawing technical field of construction, particularly a kind of intelligence pipe drawing device.
Background technology
Cut-pff wall is as cost-effective vertical seepage control system, and joint construction is to ensure that the critical process of cut-pff wall anti-seepage effect and construction quality.The cut-pff wall joint construction technology that extubation is low as a kind of cost, work efficiency is high, construction quality is good, present stage is widely used in impervious wall construction.The key technology of extubation construction has been in that the time of pulling out and has acted the control pulling out pressure, due to all uncertain factors in construction, as led wall load-bearing and breaking, drawbench fault or act the time of pulling out and control too late etc., cause failing to rise in time to pull out, will appear from " cast tube " accident, gently then schedule delays, increase construction cost, heavy then affect impervious wall construction quality and anti-seepage effect, bring tremendous influence to engineering.Therefore, the pressure in real-time collecting tube drawing process, displacement data, and then to tube drawing work progress rises the time of pulling out and rise pull out pressure be controlled research, be just particularly important.
Data collection in present stage tube drawing process, mainly adopt the mode of hand-kept, the needs of real-time collecting can not be met, can not in the whole process of complete documentation tube drawing, pressure and drawbench displacement stroke, it is impossible to for acting the time of pulling out and acting the control research the most direct data of offer pulling out pressure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of intelligence pipe drawing device, it is possible to the drawbench stroke in Real-time Collection work progress pulls out pressure data with rising, and information is displayed, transmits.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of intelligence pipe drawing device, including drawbench, drawbench is equiped with data acquisition unit, data acquisition unit includes MCU, stay-supported type displacement sensor, pressure transducer, concrete surface elevation detector, it is characterized in that: described stay-supported type displacement sensor, pressure transducer, concrete surface elevation detector are all connected with MCU, and MCU is also connected with power module and display module.Described MCU is also connected with alarm module, and alarm module is sound and light alarm module, and is provided with the display lamp of different colours.
Preferably, described MCU is also connected with memory module, key-press module, communication interface.
Preferably, described stay-supported type displacement sensor is fixedly installed in the fixing end of drawbench by base, and the stay cord bondage of stay-supported type displacement sensor is in the mobile terminal of drawbench.
Preferably, the big I of described base is arranged according to the size of stay-supported type displacement sensor.
Preferably, described pressure transducer is connected with the stock solution pressure pipe of drawbench by tee T.
Preferably, described MCU is also connected with wireless communication module, and wireless communication module is connected with control terminal again.
