Since the sector-shaped groove inside the rotary disk is in fit with the control rod, the control rod can be controlled to move inwards by rotating the rotary disk, and then the three jaws move towards the center, so as to fix the end of the cable, which is convenient and fast. And after fixation, the position of the rotary disk can be fixed through the positioning pin holes and positioning pins, which can effectively avoid the loosening of the jaws and has a good fixing effect; further, by providing a movable chuck assembly that can move left and right, only by controlling the movable chuck assembly to move away from the fixed chuck assembly through a hydraulic rod, and in cooperation with the use of a tensile force sensor, the tensile performance of the cable can be accurately measured.

[0024] Embodiment 1

[0025] As Figures 1 - 3As shown in the figure, a cable tensile property detection device proposed by the present utility model includes a bottom plate 1, a clamping seat 10, a clamping assembly 11, a tensile force detection assembly, and a lifting drive assembly. The bottom plate 1 is connected to a U-shaped frame 2, the U-shaped frame 2 is connected to a control host 3, a display 4 electrically connected to the control host 3 is arranged on the housing of the control host 3, and the U-shaped frame 2 is slidably connected to a movable plate 5. Sliding grooves 201 are arranged on the vertical rods on both sides of the U-shaped frame 2, and the two ends of the movable plate 5 are respectively inserted into the sliding grooves 201 on the corresponding sides and slidably connected to the inner walls thereof. Two groups of clamping seats 10 are respectively connected to the bottom plate 1 and the movable plate 5, and the cable end insertion ports of the two groups of clamping seats 10 face each other. Two groups of clamping assemblies 11 are respectively connected to the two groups of clamping seats 10. The clamping assembly 11 includes a rotating shaft 111, a gear 112, a connecting rod 113, a vertical plate 114, a sleeve 117, a rack 118, and a hydraulic cylinder 119. A jack is arranged in the middle of the clamping seat 10, and a number of storage holes 1001 communicating with the jack are arranged in a circular array on the clamping seat 10. Each rotating shaft 111 is respectively located in the storage holes 1001 on the corresponding side and rotatably connected to the inner wall thereof, and each rotating shaft 111 in each group of storage holes 1001 includes two upper and lower ones. The rotating shaft 111 is connected to the gear 112 and the connecting rod 113. The two connecting rods 113 in the same storage hole 1001 are parallel to each other and connected to the same vertical plate 114, and the connecting rods 113 on the clamping seat 10 connected to the bottom plate 1 all incline downward, and the connecting rods on the clamping seat 10 connected to the movable plate 5 all incline upward. The sleeve 117 is sleeved outside the clamping seat 10 and slidably connected to the outer wall thereof. The sleeve 117 is connected to each rack 118, and each rack 118 is respectively meshed and connected to the two gears 112 on the corresponding side. The hydraulic cylinder 119 is connected to the clamping seat 10 and drives the sleeve 117 and the rack 118 to slide up and down to adjust the distance between the vertical plates 114. The mutually approaching ends of the vertical plates 114 are connected to a flexible gasket 115, and a number of anti-slip teeth are arranged on the mutually approaching sides of the flexible gaskets 115. The tensile force detection assembly is connected to the movable plate 5 and one of the clamping seats 10, and the tensile force detection assembly is electrically connected to the control host 3. The tensile force detection assembly includes a pressure sensor A7. The pressure sensor A7 is connected to the upper end surface of the movable plate 5. The movable plate 5 is slidably connected to a suspension rod 8. The top end of the suspension rod 8 is connected to a limiting plate 9, and the bottom end of the suspension rod 8 is connected to the clamping seat 10. The limiting plate 9 is located above the movable plate 5, and the lower surface of the limiting plate 9 abuts against the detection end of the pressure sensor A7. The lifting drive assembly is connected to the U-shaped frame 2 and drives the movable plate 5 and the clamping seat 10 connected thereto to lift. The lifting drive assembly includes a linear module 6. The linear module 6 is located in the sliding groove 201 and slidably connected to the inner wall thereof, and the two ends of the movable plate 5 are respectively connected to the output ends of the linear modules 6 on both sides.

[0026] In this embodiment, both ends of the cable sample are respectively inserted into the jacks of two clamping seats 10. Subsequently, the clamping assemblies 11 on the two clamping seats 10 are activated. At this time, the hydraulic cylinder 119 drives the sleeve 117 to slide, thereby driving the rack 118 to slide. During the sliding process of the rack 118, the gear 112, the rotating shaft 111, and the connecting rod 113 are driven to rotate, so that each vertical plate 114 approaches synchronously to clamp the cable. Subsequently, the linear module 6 is activated, and the linear module 6 pulls up the movable plate 5, and the cable is gradually tightened. When the cable is tightened, the pulling force acts on the vertical plate 114 in the reverse direction, and the vertical plate 114 is obliquely supported by the connecting rod 113. Therefore, the tighter the cable is tightened, the tighter the vertical plate 114 clamps. During the cable tightening process, since the limiting plate 9 presses on the pressure sensor A7, the pressure sensor A7 detects the pressure signal and feeds it back to the control host 3. After the control host 3 processes the signal, the result is displayed on the display 4. When the detection is completed, the hydraulic cylinder 119 is activated to drive the sleeve 117 to slide in the reverse direction, and then the reverse-sliding rack 118 drives the gear 112, the rotating shaft 111, and the connecting rod 113 to rotate in the reverse direction, so that the distance between the vertical plates 114 is enlarged, facilitating the extraction of the cable end.
