Abstract
The present invention relates to a kind of composite insulator hardware locking pin tension tester, comprise frame, its innovative point is: central rack is fixed with an installation seat, is provided with fixed pulley directly over described installation seat; The bottom of frame is provided with the drive motor of a band speed reduction unit, connecting steel wire ropes on the output shaft of described speed reduction unit, joining shackle after fixed pulley walked around by wire rope, describedly unload the suspension hook buckling mounting strap pulling force sensor, the output signal access Programmable Logic Controller of pulling force sensor, the upper outside of frame is provided with the touch-screen be connected with Programmable Logic Controller.Be placed in by gold utensil in metal installation base, the locking pin of hook metal, pulls wire rope by drive motor, pulls suspension hook again by wire rope, and operating personnel observe instant pulling force by touch-screen, thus accurately judges whether the pulling force of locking pin meets the requirements.Without the need to detecting manually, while reduction labour intensity, improve detection efficiency and accuracy.
Description
Technical field
The present invention relates to a kind of tension tester, particularly a kind of composite insulator hardware locking pin tension tester.
Background technology
End part of composite insulator gold utensil is as the key element in DC power transmission line, and play a part to support and insulated conductor, it needs to test the locking pin pulling force of insulator hardware, to ensure the reliability of work in the fabrication process.Traditional detection method adopts artificial foot-operated spring balance, and the hook portion of spring balance hooks gold utensil, manually holds gold utensil and upwards lifts to check.The shortcoming of this kind of detection method is: hand labor intensity is large, and misreading, easily appear in read untrue, the very big accuracy that have impact on detection.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of labor strength is low, detection efficiency is high and composite insulator hardware locking pin tension tester accurately.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of composite insulator hardware locking pin tension tester, comprise frame, its innovative point is: described central rack is fixed with an installation seat, is provided with fixed pulley directly over described installation seat; The bottom of frame is provided with the drive motor of a band speed reduction unit, connecting steel wire ropes on the output shaft of described speed reduction unit, joining shackle after fixed pulley walked around by described wire rope, describedly unload the suspension hook buckling mounting strap pulling force sensor, the output signal access Programmable Logic Controller of described pulling force sensor, the upper outside of frame is provided with the touch-screen be connected with Programmable Logic Controller.
The invention has the advantages that: during use, gold utensil is placed in metal installation base, the locking pin of hook metal, wire rope is pulled by drive motor, suspension hook is pulled again by wire rope, now pulling force sensor is by real-time pull transfer to touch-screen, and operating personnel observe instant pulling force by touch-screen, thus accurately judges whether the pulling force of locking pin meets the requirements.Without the need to detecting manually, while reduction labour intensity, improve detection efficiency and accuracy.
Accompanying drawing explanation
Fig. 1 is composite insulator hardware locking pin tension tester structural representation of the present invention.
Embodiment
As shown in Figure 1, frame 1, installation seat 2, fixed pulley 3, drive motor 4, wire rope 5, shackle 6, pulling force sensor 7, suspension hook 8, Programmable Logic Controller 9, touch-screen 10 is comprised.
The middle part of above-mentioned frame 1 is fixed with an installation seat 2, and this installation seat 2 has the cylindrical hole of a horizontal direction, and the top in hole has groove.
Fixed pulley 3 is provided with directly over installation seat 2, the bottom of frame 1 is provided with the drive motor 4 of a band speed reduction unit, connecting steel wire ropes 5 on the output shaft of speed reduction unit, the rear joining shackle 6 of fixed pulley 3 walked around by this wire rope 5, the suspension hook 8 of mounting strap pulling force sensor 7 in shackle 6, the output signal access Programmable Logic Controller 9 of pulling force sensor 7, the upper outside of frame 1 is provided with the touch-screen 10 be connected with Programmable Logic Controller 9, and the control enclosure of drive motor 4 is connected with Programmable Logic Controller 9.
Principle of work: gold utensil level is placed in cylindrical hole, press touch-screen 10 by the locking pin of hook gold utensil, start drive motor 4 and pull wire rope 5, suspension hook 8 is pulled again by wire rope 5, now pulling force sensor 7 by real-time pull transfer to Programmable Logic Controller 9, and shown by touch-screen 10, operating personnel observe instant pulling force by touch-screen 10, thus accurately judge whether the pulling force of locking pin meets the requirements.
