Description

Technical Field

[0002] In the production and use of cables, the strength of the cables is one of the key factors that determine their safety performance. In order to ensure the reliability of the cables in various application environments, they must be subjected to strict strength testing.

Although the above patent can detect the strength of the cable, it can only detect the strength of the cable in a linear stretching state. However, in actual applications, the cable often needs to withstand a complex mechanical environment, especially when stretched in a bent state. The stress state of the internal fiber of the cable in the bent state is significantly different from that in a linear stretch. At the bend, the fiber of the cable may produce additional stress and strain due to bending, thereby increasing the risk of cable breakage.

The L-shaped plate 16 is symmetrically fixed to the middle of the left and right fixed seats 6. The winding roller 161 is rotatably connected between the front and rear L-shaped plates 16. A coil spring Ⅰ1611 is arranged between the winding roller 161 and the L-shaped plate 16. A material blocking cloth 162 is wound between the winding roller 161 and the L-shaped plate 16.

When the fiber passes through the opening 163 and falls downward, the collecting frame 166 can collect and process the fiber. Four through holes 1671 are evenly spaced on the base 1, and the through holes 1671 correspond to the guide rod 165. A pushing component is arranged between the fixed seat 6 and the U-shaped guide rail 1661.

The straight hole plate 169 is inclined, and the inner side of the straight hole plate 169 is slidably connected to the contact rod 1610. When the straight hole plate 169 moves, the straight hole plate 169 can drive the contact rod 1610 to move up and down.

[0033] First, the device is pushed to the designated area by the universal wheel 5, and the electric limit block 2 is started to move downward to contact the ground to generate friction, and the electric limit block 2 is closed, which makes the base 1 more firmly placed, and then the tension value is set to a qualified value of the cable, and the cable to be tested is fixed between the limit balls 8 on the left and right sides, and the dual-axis motor 152 is started to rotate forward to drive the left and right screw rods 153 to rotate forward, and the screw 153 rotates forward to drive the left and right U-shaped plates 151 to move away from each other, and the U-shaped plates 151 drive the fixed seats 6 on the left and right sides to move away from each other, and the fixed seats 6 drive the left and right movable seats 4 to move away from each other, and the universal wheel 5 guides the movement of the movable seat 4 The movable seat 4 moves to drive the articulated frame 154 to unfold, the fixed seat 6 drives the tension sensors 81 on the left and right sides to move away from each other through the fixed column 7, the tension sensor 81 drives the limit balls 8 on the left and right sides to move away from each other, the limit balls 8 on the left and right sides pull the cable, that is, the strength of the cable in the horizontal state is detected, and the tension sensor 81 detects the tension value. After the strength detection of the cable in the horizontal state is completed, the cylinder 14 is started, the telescopic rod of the cylinder 14 is shortened to drive the driving plate 141 to move upward, the driving plate 141 moves upward to drive the sliding rod 11 to move upward, the sliding rod 11 moves upward to drive the arc plate 12 to move upward, and the arc plate 12 moves upward The arc plate 12 pushes the cable to bend upward, so that the cable can be tested for strength in the bent state. The cylinder 14 is closed, and the drive plate 141 stops driving the arc plate 12 to move upward through the slide bar 11. In this way, the cable can be simulated to be tested for strength in a bent state and in a horizontal state, so as to conduct a comprehensive test. When the tension sensor 81 detects that the tension value reaches the set value, if the cable is broken, it means that the cable strength is unqualified, otherwise it is qualified. At the same time, the tension sensor 81 controls the dual-axis motor 152 to be turned off through the control module, and the limit ball 8 stops pulling the cable. Then the dual-axis motor 152 is started to reverse and drive the left and right side screws 153 to reverse. 153 drives the left and right U-shaped plates 151 to move and reset in the direction of approaching each other, and the U-shaped plates 151 drive the left and right fixed seats 6 to move and reset in the direction of approaching each other, and the fixed seats 6 drive the left and right limit balls 8 to move and reset in the direction of approaching each other through the fixed columns 7 and the tension sensor 81, and the fixed seats 6 drive the left and right movable seats 4 to move and reset in the direction of approaching each other, thereby reducing the space occupied by the device, and the movable seat 4 resets and drives the articulated frame 154 to be retracted, and then the tested cable is removed from the limit ball 8. When all the cables are fully tested, the electric limit block 2 is started to move upward and reset to be out of contact with the ground, and the device can be pushed to move through the universal wheel 5; Fiber collection: When the fixed seats 6 on the left and right sides move away from each other, the fixed seats 6 drive the winding rollers 161 on the left and right sides to move away from each other through the L-shaped plate 16, and the winding rollers 161 move away from each other and rotate to release the blocking cloth 162, and the coil spring I 1611 is compressed. At the same time, the fixed seat 6 also drives the elastic telescopic rods II 168 on the left and right sides to move away from each other, and the elastic telescopic rods II 168 drive the one-shaped perforated plates 169 on the left and right sides to move away from each other, and the one-shaped perforated plates 169 drive the contact rods 1610 on the left and right sides to move downward, and the contact rods 1610 move downward, driving the U-shaped guide rails 1661 to move downward, and the compression springs 167 are compressed, and the U-shaped guide rails 1661 move upward. The downward movement drives the middle part of the material blocking cloth 162 to move downward in an inclined state, and the U-shaped guide rail 1661 also drives the guide rod 165 to move downward into the through hole 1671. When the contact rod 1610 moves downward to the maximum stroke in the straight hole plate 169, the straight hole plate 169 stops driving the contact rod 1610 to move downward, and the contact rod 1610 stops the straight hole plate 169 from moving. The straight hole plate 169 limits the elastic telescopic rod II 168, and the fixed seat 6 continues to move to pull the elastic telescopic rod II 168 for stretching. When the cable strength breaks, the broken fibers fall downward onto the material blocking cloth 162. Since the middle part of the material blocking cloth 162 is in an inclined state, the fibers on the material blocking cloth 162 pass through the opening 163 and fall onto the collection frame 1 66, the collecting frame 166 collects the fibers. Since the articulated frame 154 is in the expanded state at this time, the articulated frame 154 will not affect the removal of the collecting frame 166, and the collecting frame 166 can be pulled forward to disengage from the U-shaped guide rail 1661, and the fibers in the collecting frame 166 are poured out for processing. After all the fibers are poured out, the collecting frame 166 is put back into the U-shaped guide rail 1661, and when the left and right fixed seats 6 move and reset in the direction of approaching each other, the fixed seat 6 drives the left and right winding rollers 161 to move and reset in the direction of approaching each other through the L-shaped plate 16, and the winding roller 161 moves and resets so that the material blocking cloth 162 is relaxed, and due to the action of the winding spring Ⅰ1611, the winding roller 161 rotates in the opposite direction to rewind the material blocking cloth 162 At the same time, the fixed seat 6 first drives the left and right elastic telescopic rods II 168 to shrink and reset, and then the fixed seat 6 drives the left and right side straight hole plates 169 to move and reset in the direction of approaching each other through the elastic telescopic rods II 168, and the straight hole plates 169 drive the contact rod 1610 to move upward and reset, and the contact rod 1610 drives the U-shaped guide rail 1661 to move upward and reset, and the compression spring 167 is reset, and the U-shaped guide rail 1661 drives the guide rod 165 to move upward and reset, and the U-shaped guide rail 1661 also drives the collecting frame 166 to move upward and reset, and at the same time, the U-shaped guide rail 1661 drives the middle part of the material blocking cloth 162 to move upward and reset, so that the fibers caused by the broken cable can be prevented from falling to the surroundings and affecting the working environment, thereby ensuring a good working environment.

[0034] See also Figure 8 and Fig. 9 As shown, the cable strength detection device also includes a shielding component installed on the fixed seat 6, the shielding component includes a support plate 17, a winding roller 171, a coil spring II 1711, a blocking cloth 172, a contact strip 173, a blocking plate 174 and an L-shaped limit block 1741, the top of the right fixed seat 6 is symmetrically fixed with a support plate 17, the upper part of the front and rear support plates 17 is rotatably connected with a winding roller 171, the winding roller 171 and the support plate 17 are connected with a coil spring II 1711, and the winding roller 171 is wound with a blocking cloth. The blocking cloth 172 can block the cable that is swinging due to the breakage when the cable breaks. A contact strip 173 is fixedly connected to the head end of the blocking cloth 172, and a blocking plate 174 is fixedly connected to the right side of the top of the left fixed seat 6. The blocking plate 174 can block and limit the contact strip 173. The upper parts of the front and rear side surfaces of the blocking plate 174 are connected to L-shaped limit blocks 1741 through damping rotation. When the L-shaped limit block 1741 rotates ninety degrees, the L-shaped limit block 1741 can limit the contact strip 173.

[0035] When the cable is fixed between the limiting balls 8 on the left and right sides, the contact strip 173 is pulled to move left, and the contact strip 173 moves left to drive the blocking cloth 172 to move left, and the blocking cloth 172 moves left to drive the winding roller 171 to reverse, and the coil spring II 1711 is compressed. When the contact strip 173 moves to the left above the blocking plate 174, the contact strip 173 is pulled downward to contact the upper part of the blocking plate 174, and the blocking plate 174 limits the contact strip 173 to prevent the contact strip 173 from moving to the right under the action of the coil spring II 1711. At this time, the blocking cloth 172 blocks the upper part of the cable, and then pulls the L-shaped limiting blocks 1741 on the front and rear sides to swing ninety degrees in the direction of approaching each other, and the L-shaped limiting blocks 1741 swing to contact the top of the contact strip 173, and the L-shaped limiting blocks 1741 limit the contact strip 173 to prevent the contact strip 173 moves upward and disengages from the blocking plate 174, affecting the use of the blocking cloth 172, thereby ensuring the stable use of the blocking cloth 172. When the cable strength is unqualified and broken, the cable will swing due to the force generated by the break, and the blocking cloth 172 blocks the swinging cable. After the cable strength test is completed, the L-shaped limit blocks 1741 on both sides are pulled to swing 90 degrees away from each other to reset, and the L-shaped limit blocks 1741 are reset and disengaged from the contact strip 173, and then the contact strip 173 is pulled upward to disengage from the blocking plate 174, and the contact strip 173 is pulled to move rightward to reset, and the contact strip 173 moves rightward to drive the blocking cloth 172 to move rightward, and the blocking cloth 172 is in a relaxed state. Due to the action of the winding spring II 1711, the winding roller 171 rotates forward to rewind the blocking cloth 172 and reset it, loosening the contact strip 173. In this way, the cable can be prevented from being injured by the swinging force of the break, thereby ensuring the safety of the operator.

[0036] See also Fig.10As shown, the cable strength detection device also includes a counterweight block 19, and the counterweight block 19 is fixedly connected to the bottom of the base 1 symmetrically.

[0037] When the electric limit block 2 limits the base 1, under the action of the counterweight block 19, the base 1 can be placed more firmly on the bottom surface for use. In this way, the base 1 can be prevented from moving and affecting the strength test of the cable, thereby ensuring the normal strength test of the cable.
