specific Embodiment approach
[0036] Specific embodiment: the two ends of the tension clamp are respectively suspended on the suspension ring 24 and the pull ring, the hydraulic cylinder 5 is controlled to shrink, and then the hydraulic cylinder 5 and the column 26 work together to pull the tension clamp, and the tension clamp is During the pulling process, due to its irregular shape, when it rotates, the tension clamp drives the disc sleeve 23 to rotate around the disc head 25, which plays the role of releasing force and controls the pressure plate 14 and the fixed seat 8 during the shrinkage process of the hydraulic cylinder 5. The structure formed by co-extruding the pressure box 16 and the box cover 15, the box cover 15 squeezes the liquid in the pressure box 16, and the squeezing force of the liquid in the pressure box 16 is transmitted to the pressure gauge 10 through the connecting pipe 11, so that the pressure The reading of Table 10 is changed, and when the tension clamp is broken, it is convenient...

The invention relates to the field of strain clamp detection, in particular to an electric power strain clamp performance detector which comprises a base, a support is fixedly connected to the edge of one side of the upper surface of the base, and a fixing base is fixedly connected to the edge of the side, away from the support, of the upper surface of the base. A horizontally-arranged hydraulic cylinder used for pulling the strain clamp is installed on the face, away from the fixing base, of the support, a penetrating hole formed in the length direction of the hydraulic cylinder is formed in the face, facing the support, of the fixing base, a column rod is inserted into the penetrating hole, and a detachable pressing disc is installed at the end, away from the hanging piece, of the column rod. An indicating piece used for detecting the withstand pressure of the strain clamp is arranged between the pressing disc and the fixing base, an annular arc-shaped groove is machined in the middle of the outer surface of the column rod, and a detecting piece used for detecting whether the arc-shaped groove is deformed or not is installed on the upper portion in the penetrating hole. The method has the following beneficial effect that the deformed column rod is prevented from influencing the accuracy of the endurance detection data of the strain clamp.
Description
technical field [0001] The invention relates to a performance detector of a power tension clamp, belonging to the field of tension clamp detection. Background technique [0002] The tension clamp is used to fix the wire to bear the tension of the wire, and hang the wire to the hardware on the tension string or tower. When testing the resistance of the tension clamp, pull the force at both ends of the tension clamp until the tension clamp breaks, and obtain the maximum tensile strength data of the tension clamp through the pressure gauge. During the process, the pendant used to limit the position of one end of the tension clamp is prone to deform before the tension clamp, which affects the accuracy of the test data of the tension clamp. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a performance detector for electrical tension clamps, so as to solve the problems raised in the above-mentioned background ...
