Abstract
The utility model discloses a pulling force test device for insulator metal fitting head locking pins, which is characterized in that: the pulling force test device comprises a base board, a metal fitting head fixing base and a cylinder which are respectively fixed at two sides of the base board; an end of a piston rod of the cylinder is provided with a draw hook which is matched with and connected with the locking pin; and the draw hook is provided with a pulling force sensor. The pulling force test device has a simple structure. The cylinder is used as a loading device for pulling the locking pin and ensuring a continuous and constant pulling force. Once the locking pin falls from the metal fitting head, a cylinder piston slowly retreats and a relatively large reaction force is prevented. Furthermore the base has a relatively large weight, thereby ensuring high stability and relatively high safety of the whole device. Furthermore, a force which is applied by the piston rod of the cylinder directly acts on the locking pin, no middle loss is caused and test accuracy is greatly improved.
Description
Technical field
The utility model relates to strength testing device, is specifically related to a kind of insulator hardware head locking pin pull force tester.
Background technology
?each corner that high voltage transmission line spreads all over the world, each parts on power transmission line must normally use under complicated climatic environment, insulator is as the vitals on power transmission line, locking pin on its gold utensil head needs through tensile test in manufacture process, to guarantee that its intensity meets request for utilization.Existing for test the device of locking pin pulling force adopt more driven by motor pulley system pull locking pin, once the wire rope bounce-back that locking pin is drawn out on pulley easily hurts people, security is poor, moreover the operational process of pulley system friction consumption mechanical energy is more, higher to the power requirement of motor.
Summary of the invention
The technical problems to be solved in the utility model is to provide the hot beam test machine of a kind of core rod of insulator, uses safety, test result accurately reliable, greatly improves the detection means of product.
The utility model is achieved through the following technical solutions:
Insulator hardware head locking pin pull force tester, it is characterized in that: comprise base plate, be separately fixed at gold utensil head holder and the cylinder of base plate both sides, the end of the piston rod of described cylinder is provided with the drag hook being connected with locking pin, and described drag hook is provided with pulling force sensor.
The further improvement project of the utility model is that described gold utensil head holder is the scroll chuck being fixed on described base plate.
The utility model further improvement project is that the cylinder seat of described cylinder is fixed in the stand of described base plate one side.
The utility model further improvement project is that the center line of the axis of described cylinder piston rod and gold utensil head pin-and-hole is on same straight line.
Compared to the prior art the utility model has the following advantages:
The utility model is simple in structure, charger with cylinder as pulling locking pin, ensure that pulling force continues balanced, once locking pin can slow retraction can not form larger reacting force from the gold utensil head cylinder piston that comes off, and the weight of base is larger, also guaranteed the steady of whole device, security is higher, moreover the power that the piston rod of cylinder applies acts directly on locking pin, there is no middle loss, greatly improved the accuracy of test.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Insulator hardware head locking pin pull force tester as described in Figure 1, comprise base plate 1, be separately fixed at gold utensil head holder 2 and the cylinder 3 of base plate 1 both sides, cylinder 3 is as also selecting other type of drive such as oil cylinder in the charger practical operation of pulling force, the end of the piston rod of cylinder 3 is provided with the drag hook 5 being connected with locking pin 4, and drag hook 5 is provided with pulling force sensor 6.Locking pin 4 in the present embodiment is R shape pin, when detection, drag hook 5 is buckled in outside R shape pin and is exposed on the annulus outside gold utensil head 8, open cylinder 3 and pull laterally locking pin 4, the external display screen of pulling force sensor 6 shows test results, and whether the tensile strength that judges locking pin 4 with this meets standard.
In the present embodiment, gold utensil head holder 2 is for being fixed on the scroll chuck on base plate 1, fixing reliable.The cylinder seat of cylinder 3 is fixed in the stand 7 of base plate 1 one sides, and in order to ensure that pulling force loads evenly, the center line of the axis of cylinder 3 piston rods and gold utensil head 8 pin-and-holes is on same straight line.
