The two clamping plates 13 are in contact with each other. A protrusion is provided on the rear side of the clamping plate 13. The clamping plate 13 can clamp the end of the braided rope. A torsion spring 131 is connected between the clamping plate 13 and the vertical rod 132.

[0031] See also Figure 7 and Figure 8As shown, the buffer assembly includes a reset spring 15, an L-shaped plate 151, a cylinder 152, an electromagnetic rod 153, a rotating assembly, a wedge block 156 and a connecting spring 157. The front side surfaces of the upper and lower fixed seats are symmetrically fixed with L-shaped plates 151. The front and rear sides of the ends of the upper and lower U-shaped rods 7 are vertical surfaces. The sides of the upper and lower L-shaped plates 151 that are away from each other are fixed with electromagnetic rods 153. The electromagnetic rods 153 can buffer the U-shaped rods 7 through magnetic force to buffer and eliminate the tension generated by the breakage of the braided rope. The diameters of the upper and lower electromagnetic rods 153 gradually increase from the ends that are close to each other to the ends that are away from each other. The sides of the upper and lower L-shaped plates 151 that are away from each other are rotatably connected with the cylinder 152. The electromagnetic rods 153 Located in the cylinder 152, wedge blocks 156 are evenly spaced and slidably connected on the left and right sides of the cylinder 152. The wedge blocks 156 can limit the U-shaped rod 7. A connecting spring 157 is connected between the wedge block 156 and the inner side of the cylinder 152. A return spring 15 is symmetrically connected between the U-shaped rod 7 and the fixed plate 6. A rotating component is arranged between the cylinder 152 and the L-shaped plate 151. When the rotating component is in operation, the rotating component can drive the cylinder 152 to rotate; the rotating component includes an electric gear 154 and an outer gear ring 155. The outer side surface of the cylinder 152 is fixedly connected with the outer gear ring 155 circumferentially away from the fixed plate 6, and the electric gear 154 is installed on the front side of the L-shaped plate 151, and the electric gear 154 is meshed with the outer gear ring 155.

[0032] First, start the electromagnetic rod 153, then press the left and right side clamps 13 to swing open, the torsion spring 131 is compressed, then move the movable end of the braided rope between the left and right side clamps 13, loosen the clamps 13, due to the action of the torsion spring 131, the left and right side clamps 13 swing back to clamp the ends of the braided rope, then start the exposure board 10 to emit light, the light shines on the braided rope and the receiver 9, the receiver 9 cooperates with the exposure board 10 to test the position of the braided rope, if the braided rope is in an inclined state, the receiver 9 controls the electric screw 14 to rotate through the control module, the electric screw 14 rotates to move horizontally through the thread, the electric screw 14 moves to drive the sliding frame 11 to move, the sliding frame 11 drives the fixed cylinder 12 to move, the fixed cylinder 12 is driven by the vertical rod 132 The movable clamp 13 moves, and the clamp 13 drives the braided rope to move. When the upper clamp 13 drives the upper part of the braided rope to move forward, the lower clamp 13 drives the lower part of the braided rope to move backward. Similarly, when the upper clamp 13 drives the upper part of the braided rope to move backward, the lower clamp 13 drives the lower part of the braided rope to move forward. This is repeated to adjust the position of the braided rope, thereby correcting the position of the braided rope so that the braided rope is in a vertical state to prevent the braided rope from being tilted for tensile performance testing, thereby improving the accuracy of the test. When the braided rope is in a vertical state, the receiver 9 controls the electric screw 14 to close through the control module, the clamp 13 stops driving the end of the braided rope to move, the exposure plate 10 is closed, and then the electric clamp 8 is started to clamp the corrected braided rope to tighten The electric screw rod 3 is fixed, and then the electric screw rod 3 is started to rotate forward. The electric screw rod 3 rotates forward to drive the upper and lower movable seats 4 to move away from each other. The movable seats 4 drive the upper and lower tension sensors 5 to move away from each other. The tension sensor 5 drives the upper and lower fixed plates 6 to move away from each other. The fixed plates 6 drive the upper and lower U-shaped rods 7 to move away from each other. The U-shaped rods 7 drive the upper and lower electric clamps 8 to move away from each other. The upper and lower electric clamps 8 move in the direction away from each other to pull the braided rope, thereby testing the tensile performance of the braided rope. The tension sensor 5 tests the tension on the braided rope. The tension sensor 5 transmits the test data to the terminal for display. When the braided rope breaks, the tension sensor 5 also After the final tension test is completed, the terminal displays the tension value when the braided rope breaks. At the same time, the electric clamp 8 moves outward due to the tension at the moment the braided rope breaks, and the reset spring 15 is compressed. The electric clamp 8 moves outward and drives the U-shaped rod 7 to move outward. The U-shaped rod 7 moves outward to the cylinder 152 and is sleeved on the electromagnetic rod 153. The electromagnetic rod 153 buffers the outward movement of the U-shaped rod 7 due to the magnetic force, thereby buffering and eliminating the tension caused by the breakage of the braided rope, and the U-shaped rod 7 moves outward and contacts the inclined surface of the wedge block 156. The U-shaped rod 7 drives the left and right wedge blocks 156 to move away from each other, and the connecting spring 157 is compressed. As the U-shaped rod 7 continues to move outward, the U-shaped rod 7 is out of contact with the inclined surface of the wedge block 156.Due to the action of the connecting spring 157, the wedge blocks 156 on the left and right sides move and reset in the direction of approaching each other. In this way, the tension caused by the break of the braided rope can be prevented from causing the U-shaped rod 7 to violently impact the device, thereby ensuring the normal use of the device. When the tension caused by the break of the braided rope is eliminated, the U-shaped rod 7 stops moving outward, and the wedge block 156 limits the U-shaped rod 7, closes the electromagnetic rod 153, and then starts the electric clamp 8 to reset and loosen the broken braided rope, pushes the left and right side clamps 13 to swing to loosen the broken braided rope ends, and then the broken braided rope can be removed, and then the electric gear 154 is started to rotate, the electric gear 154 rotates to drive the outer gear ring 155 to rotate, and the outer gear ring 155 rotates to drive the cylinder 152 to rotate The cylinder 152 rotates to drive the wedge block 156 to rotate, and the wedge block 156 rotates and slides on the U-shaped rod 7. When the wedge block 156 rotates 90 degrees, the electric gear 154 is turned off, and the wedge block 156 rotates to correspond to the vertical surface of the end of the U-shaped rod 7. The wedge block 156 is out of contact with the U-shaped rod 7. Due to the action of the reset spring 15, the upper and lower U-shaped rods 7 move inwards to reset, driving the upper and lower electric clamps 8 to move inwards to reset, and the electric gear 154 is started to rotate in the opposite direction to drive the outer gear ring 155 to rotate in the opposite direction. The outer gear ring 155 drives the cylinder 152 to rotate in the opposite direction by 90 degrees. The cylinder 152 drives the wedge block 156 to rotate in the opposite direction by 90 degrees to reset. The electric gear 154 is turned off, and the tension value on the terminal can be checked to determine whether the tensile performance of the braided rope is qualified.

[0033] See also Fig. 9 As shown, the braided rope tensile performance testing device also includes a blowing assembly installed on the support frame 2, the blowing assembly includes a guide sleeve 16, a U-shaped guide rod 161, a fixed shaft 162, an arc cover plate 163, an blowing assembly and a sponge sleeve 167, the left and right side surfaces in the support frame 2 are symmetrically fixed with guide sleeves 16, the U-shaped guide rod 161 is slidably connected between the guide sleeves 16 on the left and right sides, and a fixed shaft 162 is fixed between the middle parts of the U-shaped guide rods 161 on the upper and lower sides, and two arc cover plates 163 are rotatably connected to the fixed shaft 162, and the arc cover plates 163 on the left and right sides cooperate with each other, and the arc cover plate 163 can cover the braided rope, and the fixed shaft A sponge sleeve 167 is provided on the middle fixed sleeve 162, and the sponge sleeve 167 can increase the friction between the hand and the arc cover plate 163. A locking assembly is provided on the arc cover plate 163, and when the locking assembly is in operation, the locking assembly can lock the arc cover plate 163; the locking assembly includes a fixing rod 165 and a buckle 166, and the fixing rod 165 is symmetrically fixed to the right side of the outer side surface of the right arc cover plate 163, and the buckle 166 is symmetrically connected to the outer side surface of the left arc cover plate 163 in an upward and downward rotation. When the buckle 166 contacts the fixing rod 165, the buckle 166 can lock the fixing rod 165 to complete the locking of the arc cover plate 163.

[0034] Initially, the air blowing pipes 164 on the left and right sides are both connected to an external air supply machine. When the braided rope after deviation correction is electrically clamped, the sponge cover 167 is held to pull the fixed shaft 162 forward. Due to the effect of the sponge cover 167, the friction with the hand can be increased, so the fixed shaft 162 can be pulled more firmly. The fixed shaft 162 moves forward to drive the U-shaped guide rod 161 to move forward. The U-shaped guide rod 161 guides the fixed shaft 162. The fixed shaft 162 moves forward and also drives the arc-shaped cover plates 163 on the left and right sides to move forward. When the arc-shaped cover plates 163 move forward to the specified position, stop pulling. The fixed shaft 162 is moved forward, and then the upper and lower buckles 166 are pulled to swing upward 90 degrees, and then the arc-shaped cover plates 163 on the left and right sides are pulled to swing toward each other and close together. The arc-shaped cover plates 163 on the left and right sides contact each other to form a circular tube to cover the braided rope. At this time, the upper and lower buckles 166 are pulled to swing downward and buckle on the fixed rod 165. The buckle 166 cooperates with the fixed rod 165 to lock the two arc-shaped cover plates 163 together to prevent the two arc-shaped cover plates 163 from being out of contact and affecting the covering of the braided rope. When the tensile strength of the braided rope needs to be improved in a hot environment, When testing, start the external air supply machine to discharge hot air into the air blowing pipe 164, and the air blowing pipe 164 sprays hot air to contact the braided rope, so that the braided rope is in a high temperature environment, and then the tensile performance of the braided rope can be tested in the high temperature environment. When the tensile performance test of the braided rope in the high temperature environment is completed, stop discharging hot air into the air blowing pipe 164, pull the buckle 166 to swing upward and disengage from the fixing rod 165, and stop locking the two arc-shaped cover plates 163, pull the arc-shaped cover plates 163 on the left and right sides to swing outward and open, and then pass the sponge cover 1 67 drives the fixed shaft 162 to move backward, and the fixed shaft 162 moves backward to drive the U-shaped guide rod 161 and the arc cover plate 163 to move backward and reset. Similarly, when it is necessary to test the tensile performance of the braided rope in a low-temperature environment, it is only necessary to start the external air supply machine to discharge the cold air into the air blowing pipe 164, and the air blowing pipe 164 will spray the cold air into contact with the braided rope, and then the tensile performance of the braided rope can be tested in a low-temperature environment. In this way, the tensile performance of the braided rope can be tested in high and low temperature environments, and the test is diversified, thereby further improving the accuracy of the test.

[0035] See also Fig.10 As shown, the braided rope tensile performance testing device also includes a transparent protective plate 17 and a handle 18. The transparent protective plate 17 is rotatably connected to the left front side of the support frame 2. The transparent protective plate 17 can block the broken braided rope. The handle 18 is fixedly connected to the right side of the front side of the transparent protective plate 17.

[0036] When the tensile strength of the braided rope needs to be tested, the handle 18 is held to pull the transparent protective plate 17 to swing forward and open, and then the braided rope is moved to the left and right clamps 13 to clamp and correct the deviation. When the braided rope is electrically clamped, the handle 18 is held to push the transparent protective plate 17 to swing backward and close, and the tensile strength of the braided rope can be tested. The operator can view the situation during the braided rope test through the transparent protective plate 17. When the braided rope breaks, the protective plate can block the braided rope that bursts out due to the break, and the transparent protective plate 17 can be pulled forward to swing open and the broken braided rope can be removed. In this way, the braided rope can be prevented from causing harm to the operator due to the breakage, thereby ensuring the safety of the operator.
