Description
Technical Field
[0001] The utility model relates to the technical field of wear test fixtures, in particular to a wear test fixture for electric power fittings. Background Art
[0002] In recent years, China has vigorously developed its Northwest power grid. However, the region's complex climate and environment are subject to persistent strong winds. Under the influence of wind, the electrical hardware used in transmission lines swings significantly, causing wear and tear, which reduces the reliability of the hardware and poses a risk to the safe operation of the power grid. To better understand the lifespan of electrical hardware in high wind conditions, wear tests on hardware are being conducted to help workers better understand the service life of electrical hardware. Suspension clamps used for erecting power lines are often used as experimental materials.
[0003] The wear test fixture used for electrical hardware in the existing technology has a single clamping direction and cannot effectively clamp the suspension clamp according to its appearance characteristics. In addition, after the simulated wear, the suspension clamp needs to be moved to the test area for strength testing, which requires disassembly and re-clamping, which is quite troublesome and delays the efficient progress of the experiment. Therefore, we propose a wear test fixture for electrical hardware. Utility Model Content
[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a wear test fixture for electrical hardware. The fixture has a reliable hardware clamping unit, and can reinforce the suspension wire clamp from multiple directions based on the appearance characteristics of the suspension wire clamp, thereby effectively ensuring the stability of the suspension wire clamp during experimental testing; and has a reliable and convenient shifting unit, which can move the hardware from the wear simulation area to the detection area for strength testing without disassembly, greatly improving the convenience of the experiment and effectively solving the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wear test fixture for electric power fittings, comprising a base, a convenient shifting unit and a fitting clamping unit;
[0006] Base: A square plate with a U-shaped and inverted mounting bracket fixedly connected to the left and right sides of its upper end;
[0007] Convenient shift unit: installed at the upper end of the mounting frame;
[0008] Hardware clamping unit: includes mounting groove, slider, clamping block, card slot and hydraulic cylinder. The convenient shifting unit contains a movable slide, which is arranged horizontally between two mounting frames. A mounting groove is provided in the middle of the upper end of the movable slide. The cross-section of the mounting groove is a T-shaped structure, and two sliders with the same T-shaped structure are slidably connected inside. Two front and rear hydraulic cylinders are embedded in the interior of the movable slide. The telescopic ends of the two hydraulic cylinders are respectively fixedly connected to the side of a slider. The lower end of the slider extends downward from the mounting groove and is fixedly connected to the upper end of the clamping block. The clamping block is a square structure, and a semicircular card slot is provided on the opposite side of the left and right clamping blocks.
[0009] The movable slide is used for the installation of the clamping assembly and can drive the clamping assembly to move, so that the hardware can be moved to the testing area for strength testing without disassembly; when the movable slide is placed above the blower on the left side of the base, the swinging movement of the hardware is generated by simulating the wind scene; the big head of the suspension wire clamp is inserted between the two clamping blocks, and the left and right hydraulic cylinders push the sliders to slide toward the middle respectively, and the slide groove is installed for the installation of the slider, and the two sliders can slide smoothly horizontally. When the left and right sliders move toward the middle, the two clamping blocks on the lower side are driven to move closer to the middle to clamp the suspension wire clamp. The slot on the inside of the clamping block can be stuck in the arc-shaped part of the big head of the suspension wire clamp, which plays a longitudinal limit fixation, thereby improving the fixing effect of the suspension wire clamp.
[0010] Furthermore, the hardware clamping unit also includes an extension block and an auxiliary clamping block. The lower end of the clamping block is fixedly connected to a triangular extension block, with the tip of the extension block facing downward and both sides of equal length. An auxiliary clamping block is fixedly connected along the hypotenuse on each of the two opposite sides of the extension blocks, one of which is fixedly connected to the front end of the left extension block, and the other is fixedly connected to the rear end of the right extension block. The extension block is used to install the auxiliary clamping block. As the clamping block moves, the two auxiliary clamping blocks form a V-shaped structure and are jointly clamped on the hypotenuse side of the large end of the suspension wire clamp, which can prevent the suspension wire clamp from moving horizontally, thereby further enhancing the clamping effect of the suspension wire clamp and ensuring that the wear test can be carried out stably and effectively.
[0011] Furthermore, the convenient shifting unit includes an inner slide and a movable carriage. A longitudinal inner slide is provided on opposite sides of the upper ends of the left and right mounting frames. The movable carriage is arranged transversely and slidably connected to the inner slide at both ends. The inner slide is used to clamp the ends of the movable carriage and enable the movable carriage to slide longitudinally.
[0012] Furthermore, the convenient shifting unit further includes a straight slot, a threaded shaft, and a tightening handwheel. The left and right mounting brackets each have a straight slot on the opposite sides of their upper ends, which is connected to the inner slide. A threaded shaft is fixedly connected to each end of the movable slide. The threaded shaft extends outward and is externally threadedly connected to a tightening handwheel. A rubber washer is fixedly mounted on the inner side of the tightening handwheel. The straight slot allows the threaded shaft to extend outward, and the movable slide can be fixed by turning the tightening handwheel on the outside.
[0013] Furthermore, the device also includes a blower, one mounted on each side of the upper end of the base, with the air outlets of both blowers facing the center of the device. The left and right blowers operate alternately under the control of a control switch, creating alternating wind directions. The alternating wind forces cause the hanging wire clamp to sway, simulating actual wear conditions.
[0014] Furthermore, the base also includes a tensioning device and a barb. The tensioning device is embedded in the rear upper end of the base, and the telescopic end of the tensioning device is fixedly connected to the barb. The barb is used to catch the hanging hook end of the suspension wire clamp. Under the action of the tensioning device, the strength of the worn suspension wire clamp can be tested.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the wear test fixture for electric hardware has the following advantages:
[0016] 1. It has a reliable hardware clamping unit. According to the appearance characteristics of the suspension wire clamp, it can achieve the reinforcement effect of the suspension wire clamp from multiple directions, thereby effectively ensuring the stability of the suspension wire clamp during experimental testing;

The slot 44 on the inner side of the clamping block 43 can be stuck in the arc-shaped part of the big head of the suspension wire clamp, which plays a longitudinal limit fixation, thereby improving the fixing effect of the suspension wire clamp.
[0029] The hardware clamping unit 4 also includes an extension block 46 and an auxiliary clamping block 47.

The extension block 46 is used to install the auxiliary clamping block 47. As the clamping block 43 moves, the two auxiliary clamping blocks 47 form a V-shaped structure and are jointly clamped on the hypotenuse side of the large end of the suspension wire clamp, which can prevent the suspension wire clamp from moving horizontally, thereby further enhancing the clamping effect of the suspension wire clamp and ensuring that the wear test can be carried out stably and effectively.
