Figure 3 The bottoms of the first driving hydraulic cylinders 14 are installed with second pressing seats 53, and the first pressing seats 33 are arranged below the second pressing seats 53 and are fixed on the support table 1, and arc-shaped grooves are arranged on the opposite surfaces of the second pressing seats 53 and the first pressing seats 33 (as indicated by an arrow A in the drawings). Figure 3 The two free ends of the cable 12 are arranged in the arc-shaped grooves between the second pressing seats 53 and the first pressing seats 33, the first driving hydraulic cylinders 14 drive the second pressing seats 53 to descend to press the cable 12, and the cable 12 is prevented from sliding.
[0041] As shown in the drawings, Figure 1 A rectangular opening 23 is arranged on the support table 1 away from the third L-shaped frame 24 on the side of the first L-shaped seat 15, and two symmetrically arranged pulling devices are arranged in the rectangular opening 23, and the two pulling devices are correspondingly arranged with the two pressing mechanisms.
[0042] As shown in the drawings, Figure 3 and Figure 4 The pulling device comprises a fourth pressing seat 40, the fourth pressing seat 40 is located above the support table 1, the fourth pressing seat 40 is a rectangular plate, guide sleeves 49 are connected to the two sides of the fourth pressing seat 40, first guide rods 36 are inserted into each guide sleeve 49, one end of the first guide rod 36 close to the first L-shaped seat 15 is connected with a first connecting seat 32, the bottom of the first connecting seat 32 is fixed on the edge of the rectangular opening 23, the other end of the first guide rod 36 is connected with a second clamping seat 18, and the second clamping seat 18 is installed on the other edge of the rectangular opening 23, so that the fourth pressing seat 40 can move back and forth along the first guide rod 36.
[0043] Two fourth clamping seats 40 are each fitted with a second L-shaped seat 38 at their top ends, which are close to each other. The two second L-shaped seats 38 are arranged opposite to each other. A second driving hydraulic cylinder 35 is vertically mounted on the top of each second L-shaped seat 38. A third clamping seat 37 is mounted on the bottom of each second driving hydraulic cylinder 35. The third clamping seat 37 is located directly above the fourth clamping seat 40. Arc-shaped grooves are formed on the opposing surfaces of the third clamping seat 37 and the fourth clamping seat 40. The cable 12 is placed in the arc-shaped groove (e.g., ...). Figure 3 (Inside the area indicated by the middle arrow B);
[0044] Support plates 22 are vertically mounted on both sides of the bottom of the fourth clamping seat 40. The support plates 22 extend from the rectangular opening 23 to the bottom of the support platform 1. The bottom of the support plates 22 is vertically fixed to the movable seat 48. A second guide rod 39 is provided through both ends of each movable seat 48. The end of the second guide rod 39 near the first L-shaped seat 15 is connected to a second connecting seat 50. The top of the second connecting seat 50 is fixedly connected to the bottom of the support platform 1. A push hydraulic cylinder 52 is connected to the middle of the side of each movable seat 48. The end of the push hydraulic cylinder 52 away from the movable seat 48 is connected to a cylinder seat 51. The top of the first guide rod is fixedly connected to the bottom of the support platform 1. The other end of the second guide rod 39 is connected to the strip mounting seat 44. The strip mounting seat 44 is installed at the bottom of the support platform 1 below the second clamping seat 18. When the hydraulic cylinder 52 extends, it drives the moving seat 48 to move. The moving seat 48, the support plate 22, the fourth clamping seat 40, and the second L-shaped seat 38 are an integral structure. Therefore, when the second driving hydraulic cylinder 35 drives the third clamping seat 37 to clamp and fix the cable 12, the cable is pulled by the movement of the moving seat 48. As the driving hydraulic cylinder 52 continues to move, the moving seat 48 will eventually break the cable 12.
[0045] like Figure 6 As shown, the movable seat 48 is provided with an L-shaped fixed seat 46 on the side away from the push hydraulic cylinder 52. The bottom of the L-shaped fixed seat 46 is fixedly connected to the mounting plate 45. Two guide seats 47 are installed on the bottom of the mounting plate 45. Two third guide rods 43 are symmetrically provided through each guide seat 47. Both ends of the third guide rods 43 are fixedly connected to the U-shaped frame 20. The top two ends of the U-shaped frame 20 are respectively connected and fixed to the bottom of the support platform 1.
[0046] Among them, a guide support shaft 21 is vertically installed in the middle of a guide seat 47 away from the moving seat 48. The other end of the guide support shaft 21 is installed through a U-shaped frame 20 away from the push hydraulic cylinder 52. A support spring 42 is sleeved on the guide support shaft 21. The two ends of the support spring 42 are respectively connected and fixed to the U-shaped frame 20 and the guide seat 47. The support spring 42 is a high-elasticity spring, so that the support spring 42 still has elasticity after the cable is pulled off.
[0047] A pressure sensor 41 is mounted on the side of the L-shaped fixed base 46. The detection head of the pressure sensor 41 is in contact with the side of the movable base 48. Figure 6 As shown, when the device is stationary, the compressive force between the pressure sensor 41 and the moving seat 48 is zero. When the hydraulic cylinder 52 is pushed to extend, it pulls the cable, which increases the pressure between the pressure sensor 41 and the moving seat 48. As the cable is gradually stretched, the vertical position of the pressure sensor also changes. Finally, the force at which the cable breaks is measured. It should be emphasized that the tensile test of the cable is carried out after the swing test, or the cable can be placed in the clamping seat for the test alone.
[0048] The top of one end of the third clamping seat 37 is vertically mounted with a second guide shaft 54, and the top of the second guide shaft 54 passes through the second L-shaped seat 38.
[0049] The top of one end of the second clamping seat 53 is vertically mounted with a first guide shaft 34, and the top of the first guide shaft 34 passes through the first L-shaped seat 15.
[0050] like Figure 1 As shown, the top of the second clamping seat 18 has two symmetrical placement slots 17, and the cable 12 is placed in the placement slots 17. The first clamping seat 16 is hinged to one end of the top of the second clamping seat 18, and the other end of the first clamping seat 16 is connected to the second clamping seat 18 by a latch.
[0051] Furthermore, a current sensor 19 is installed at the end of the support platform 1. The current sensor 19 is connected in series with the cable 12. The current sensor 19 can also detect the magnitude of the current flowing through the cable. The two ends of the cable can be connected to the power supply to form a circuit. Both the current sensor 19 and the pressure sensor are connected to a computer or controller via a data cable.
[0052] A baffle 57 is vertically installed at one end of the support platform 1. Two counters 58 are installed on the side of the baffle 57. One counter counts the swing of the second connecting plate 55, and the other counter counts the swing of the first connecting plate 6. The counters are either ultrasonic counters or infrared counters. The counters are connected to a computer or controller via a data cable.
[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
