Abstract
The utility model relates to a composite insulator fitting locking pin tensile testing machine, which comprises a frame. The tensile testing machine is innovative in that the central part of the frame is fixedly provided with a fitting installing seat; a fixed pulley is arranged right above the fitting installing seat; the bottom of the frame is provided with a driving motor with a decelerator; a wire rope is connected on the output shaft of the decelerator; the wire rope is connected with a shackle after passing through the fixed pulley; a hook with a tension sensor is arranged on the shackle; output signals of the tension sensor are accessed to a programmable controller; and a touch screen connected with the programmable controller is arranged on the outer side of the frame upper part. A fitting is placed inside the fitting installing seat. The hook makes a locking pin of the fitting hooked. The wire rope is driven by the driving motor to draw the hook. An operator can observe instant tension through the touch screen so as to judge whether the tension of the locking pin is in accordance with the requirements or not. No manual detection is needed. The labor intensity is lowered while the detection efficiency and the detection accuracy are enhanced.
Description
Technical field
The utility model relates to a kind of tension tester, particularly a kind of composite insulator hardware locking pin tension tester.
Background technology
The end part of composite insulator gold utensil plays a part to support and insulated conductor that it need to be tested the locking pin pulling force of insulator hardware in manufacture process as the key element in the DC power transmission line, to guarantee the reliability of work.Traditional detection method adopts artificial foot-operated spring balance, and the hook portion of spring balance is hooked gold utensil, manually holds gold utensil and upwards lifts to check.The shortcoming of this kind detection method is: hand labor intensity is large, and misreading appears in read untrue easily, the very big accuracy that detects that affected.
Summary of the invention
The technical problems to be solved in the utility model provides 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, the technical solution of the utility model 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 the described installation seat; The bottom of frame is equipped with a drive motor with speed reduction unit, connecting steel wire ropes on the output shaft of described speed reduction unit, described wire rope is walked around joining shackle behind the fixed pulley, the described suspension hook of buckling the mounting strap pulling force sensor that unloads, the output signal access Programmable Logic Controller of described pulling force sensor, the upper outside of frame is equipped with the touch-screen that is connected with Programmable Logic Controller.
The utility model has the advantage of: during use, gold utensil is placed in the metal installation base, suspension hook hooks the locking pin of metal, by drive motor pulling wire rope, spur again suspension hook by wire rope, to touch-screen, operating personnel can observe instant pulling force by touch-screen to pulling force sensor with real-time pull transfer at this moment, thereby whether the pulling force of accurately judging locking pin meets the requirements.Need not to detect manually, when reducing labour intensity, improved detection efficiency and accuracy.
Description of drawings
Fig. 1 is the utility model composite insulator hardware locking pin tension tester structural representation.
Embodiment
As shown in Figure 1, comprise 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.
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.
Be provided with fixed pulley 3 directly over the installation seat 2, the bottom of frame 1 is equipped with a drive motor 4 with speed reduction unit, connecting steel wire ropes 5 on the output shaft of speed reduction unit, this wire rope 5 is walked around fixed pulley 3 rear joining shackles 6, the suspension hook 8 of mounting strap pulling force sensor 7 in the shackle 6, the output signal access Programmable Logic Controller 9 of pulling force sensor 7, the upper outside of frame 1 is equipped with the touch-screen 10 that is connected with Programmable Logic Controller 9, and the control enclosure of drive motor 4 is connected with Programmable Logic Controller 9.
Principle of work: the gold utensil level is placed in the cylindrical hole, that presses touch-screen 10 hooks the locking pin of gold utensil by suspension hook, start drive motor 4 pulling wire rope 5, spur again suspension hook 8 by wire rope 5, this moment pulling force sensor 7 with real-time pull transfer to Programmable Logic Controller 9, and by touch-screen 10 demonstrations, operating personnel can observe instant pulling force by touch-screen 10, thereby whether the pulling force of accurately judging locking pin meets the requirements.
