Abstract
The utility model discloses a detection device of a stress sensor, comprising a dynamometer, a chain hoist, a steel wire rope, a steel wire rope clip, a fixed pulley, a computer and a printer, wherein the fixed pulley, the computer and the printer adopt a fixed pulley, a computer and the printer in a wire winding machine system; the fixed pulley is fixed at the lower end of the stress sensor; one end of the steel wire rope is fixed together with a pre-stress steel wire through the steel wire rope clip and the other end of the steel wire rope winds around the fixed pulley and then is connected with the upper end of the dynamometer; the lower end of the dynamometer is connected with the upper end of the chain hoist; the lower end of the chain hoist is fixed on the ground or is fixed on a fixed object for bearing pull force; a data output end of the stress sensor is connected with the computer; and the computer is connected with the printer. With the adoption of the detection device, the stress sensor does not need to be detached and the stress sensor can be detected and calibrated in time at a fixed period; and the detection device of the stress sensor has the advantages of convenience for installation and detachment, simplicity in operation, direct observation and rapidness for detection, brings the convenience for the construction, improves the production efficiency and reduces the manufacturing cost of products.
Description
Technical field
The utility model relates to a kind of pick-up unit of strain gauge.
Background technology
Twining silk is the important procedure that Prestressed concrete cylinder pipe (PCCP) is produced; Twine that need to answer power apparatus be that steel wire applies prestress in the process of silk; For accurately holding the stress of compressor wire in winding process,, produce specification product to reach the stress requirement of Prestressed concrete cylinder pipe; Need strain gauge to monitor the prestress size on the steel wire, so that the prestressed error that timely more normal stress device applies.But because mounted strain gauge needs calibration before using, after use a period of time, it also can produce display error; Need calibration in time,, must take off strain gauge and detect calibration to special detection department because the scene does not have calibration detection apparatus now; Need another strain gauge replacement work, this has not only brought construction to manufacturer inconvenience has influenced production efficiency; And must prepare the replacement strain gauge, also increase the production of products cost.
The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art; A kind of pick-up unit of strain gauge is provided; Use this pick-up unit, need not strain gauge is pulled down, at the scene with regard to timely counter stress sensor detect, calibration operation.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of pick-up unit of strain gauge, and it comprises dynamometer, bottle gouard moved by hands, wire rope, wire line clamp, fixed pulley, computing machine and printer; Described fixed pulley, computing machine and printer adopt and twine the intrasystem fixed pulley of a machine, computing machine and printer; Fixed pulley is fixed on the lower end of strain gauge; Wire rope one end is fixed together through wire line clamp and compressor wire; The other end is walked around the upper end that is connected dynamometer behind the fixed pulley; The lower end of dynamometer is connected the bottle gouard moved by hands upper end; The bottle gouard moved by hands lower end is fixed on ground or is fixed on the fixed object that bears pulling force, and the data output end of strain gauge connects computing machine, and computing machine connects printer.
When using the utility model counter stress sensor to detect; At first each equipment of the utility model syndeton according to the utility model is installed on strain gauge and the compressor wire; Move bottle gouard moved by hands and produce tension; Tension acts on the compressor wire through dynamometer, fixed pulley, wire rope; At this moment the power on the power+wire rope on power=dynamometer of receiving of sensor, the power on the wire rope is the pulling force that receives of compressor wire just, the power that the power of the power=wire rope on the dynamometer=1/2 strain gauge receives.Like this, because the precision of dynamometer is very high, as long as see the data of reality on the dynamometer, just can calculate the actual power that receives of strain gauge, comparing with its power that shows at computing machine just to obtain the display error of strain gauge; Regulate strain gauge, its error is made zero.After the counter stress sensor finishes, remove each equipment of the utility model, recover former preparation of construction and can recover construction.The utility model installation and removal are convenient.Use this pick-up unit, need not strain gauge is pulled down, just can be in time regularly the counter stress sensor detect, calibration operation.It is simple to operate, and intuitive display detects bug, and construction has been brought convenience, has improved production efficiency, has reduced the production of products cost.The utility model is used to detect and twines the deviation that a thread machine stress system occurs, and also can be used for need applying the deviation that prestressed system occurs to other and detects.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further description.
As shown in Figure 1, present embodiment is used for the detection to the pull-type sensor 1 of S type.It comprises CLY-50 dynamometer 2,5T bottle gouard moved by hands 3, wire rope 4, wire line clamp, fixed pulley 5, computing machine 6 and printer 7.Fixed pulley 5, computing machine 6 and printer 7 adopt and twine the intrasystem fixed pulley of a machine, computing machine and printer.The top of the pull-type sensor 1 of S type is fixed on and twines on the machine pylon 8, and fixed pulley 5 is fixed on the lower end of the pull-type sensor 1 of S type.Wire rope 4 one ends are fixed together through wire line clamp and compressor wire; The other end is walked around the upper end that is connected CLY-50 dynamometer 2 behind the fixed pulley 5; The lower end of CLY-50 dynamometer 2 is connected 5T bottle gouard moved by hands 3 upper ends; 5T bottle gouard moved by hands 3 lower ends fix on the ground, and the data output end of the pull-type sensor 1 of S type connects computing machine 6, and computing machine 6 connects printer 7.
If detect the strain gauge of other model, can adopt the dynamometer and the bottle gouard moved by hands of other model.
