Description

Technical Field

[0001] The invention belongs to the technical field of cable stranding machines, in particular to a fixed-point parking and feeding device for a power cable stranding machine. Background Art

[0002] A stranding machine is a type of wire and cable processing equipment widely used for stranding various types of soft and hard conductors, as well as electronic wires. It generally consists of a frame, a stranding system, a tension adjustment system, and a take-up mechanism. The frame is the supporting structure of the entire machine. The stranding system consists of a series of rotating dies, which are used to twist multiple wires together according to a specific pattern. The tension adjustment system is used to adjust the tension of the wires during the twisting process, and the take-up mechanism reels the stranded wires.

[0003] Since a stranding machine needs to be equipped with multiple cable rollers, and the cable rollers are heavy, even using auxiliary loading devices often requires workers to align them. The process even requires manual adjustment of the position and angle of the cable rollers and the stranding machine. Therefore, not only does it increase the labor intensity of the loading personnel, but it also makes it difficult to ensure the accuracy and efficiency of loading. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention proposes a fixed-point parking loading device for a power cable stranding machine. This invention primarily addresses the problem that existing cable stranding machine loading devices require workers to perform centering and even manual adjustment of the position and angle between the cable rollers and the stranding machine. This not only increases the loading worker's workload but also makes it difficult to ensure loading accuracy and efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problems is: the present invention provides a fixed-point parking and loading device for a power cable stranding machine, including a base, a lifting mechanism, a horizontal transfer mechanism, a movable support plate, a centering mechanism, a limiting mechanism and an angle adjustment mechanism; the base is provided with the lifting mechanism for driving the horizontal transfer mechanism to lift up and down; the horizontal transfer mechanism is used to drive the movable support plate above to move horizontally; the angle adjustment mechanism is provided at one end of the movable support plate; the angle adjustment mechanism is used to adjust the angle of the cable roller thereon; the centering mechanism and the limiting mechanism are provided on the angle adjustment mechanism; the centering mechanism is used to limit the axial position of the cable roller; the limiting mechanism is used to limit the position of the axis of the cable roller.

[0006] During operation, the power cable stranding machine uses a fixed-point parking loading device to place the wire roller placement frame corresponding to the cable stranding machine. In the initial state, the lifting mechanism is in the lowest position, and the horizontal transfer mechanism is in a retracted state away from the cable stranding machine; the cable roller to be installed is rolled onto the movable support plate, and then pushed to the centering mechanism on the angle adjustment mechanism. The axial position of the cable roller is limited by the centering mechanism, and the cable roller is continued to be rolled so that it contacts the limiting mechanism. The limiting mechanism limits the position of the cable roller axis, and then the controller controls the angle adjustment mechanism through an electrical signal to carry the cable roller that has completed the position limit in the horizontal plane to rotate 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine; then the controller controls the angle adjustment mechanism through an electrical signal to carry the cable roller that has completed the position limit in the horizontal plane to rotate 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine; then the controller controls the angle adjustment mechanism through an electrical signal to The signal controls the horizontal transfer mechanism to move the cable roller carried on the movable support plate to the bottom of the roller placement rack of the cable stranding machine. The controller then controls the lifting mechanism through electrical signals to send the cable roller into the roller placement rack of the cable stranding machine in the vertical direction. Finally, the movable tightening shaft on the roller placement rack for locking the cable roller is locked, thereby realizing semi-automatic loading of the power cable stranding machine that is parked at a fixed point. In this case, the heavier cable roller is transported to the roller placement rack of the cable stranding machine through the loading device. The centering mechanism and the limiting mechanism are used for positioning during the process, thereby improving the accuracy and efficiency of loading. The loading is carried out by the lifting mechanism, the horizontal transfer mechanism and the angle adjustment mechanism and is automatically controlled by the controller, thereby further improving the accuracy and efficiency of loading.

[0007] Preferably, the fixed-point parking and loading device for the power cable stranding machine also includes an alignment mechanism; the alignment mechanism is arranged on the other end of the movable support plate; the alignment mechanism includes a first jacking roller frame, a first jacking cylinder, a second jacking roller frame, a second jacking cylinder, a push plate and a pushing cylinder; two strip grooves are arranged in parallel on the movable support plate; the first jacking roller frame and the second jacking roller frame are respectively arranged in the strip grooves; the lower end of the first jacking roller frame is connected to the cylinder rod end of the first jacking cylinder; the cylinder body of the first jacking cylinder is fixedly connected to the movable support plate; the lower end of the second jacking roller frame is connected to the cylinder rod end of the second jacking cylinder; the cylinder body of the second jacking cylinder is fixedly connected to the movable support plate; a push-pull groove is provided on the movable support plate between the two strip grooves; the push plate is slidably connected in the push-pull groove; the lower end of the push plate is fixedly connected to the cylinder rod end of the pushing cylinder; the pushing cylinder is fixedly connected to the movable support plate.

[0008] During operation, the cable roller to be installed is rolled to the position of the alignment mechanism on the movable support plate, and the controller controls the first lifting cylinder and the second lifting cylinder to extend the cylinder rod at the same time through electrical signals, and then lifts the cable roller through the first lifting roller frame and the second lifting roller frame. Since the first lifting roller frame and the second lifting roller frame are parallel to each other, the cable roller is lifted while its own axis is aligned with the first lifting roller frame and the second lifting roller frame. Then the controller controls the push cylinder to pull the push plate through electrical signals, and the push plate pushes the cable roller along the axis to the middle of the movable support plate to align, so that the axial position of the cable roller is aligned with the centering mechanism, and there is no need to manually adjust the angle and position of the cable roller to push it into the centering mechanism, thereby reducing the labor intensity of the loading personnel while improving the accuracy and efficiency of loading. The push plate and the pushing cylinder can be set up in one group on each side of the movable support plate, or in one group only on one side; if only one group is set up, when the cable roller is placed on the movable support plate, the cable roller needs to be placed close to that side, so that the push plate can adjust the cable roller within the effective stroke.

[0009] Preferably, the first lifting cylinder and the second lifting cylinder are separately connected to the controller via electrical signals; after the alignment mechanism aligns the cable roller with the centering mechanism, the controller separately controls the second lifting cylinder close to the centering mechanism to retract. Since the first lifting cylinder is still in an extended state at this time, the cable roller rolls toward the centering mechanism under the action of its own weight after the second lifting cylinder retracts, so there is no need to manually push the cable roller to roll toward the centering mechanism, thereby reducing the labor intensity of the loading personnel. By setting a back pressure valve in the retraction air path of the second lifting cylinder, the speed of retraction of the cylinder rod of the second lifting cylinder is controlled, and the rolling speed of the cable roller is controlled, so that the impact force of the cable roller rolling to the centering mechanism and the limiting mechanism is controlled.

[0010] Preferably, the angle adjustment mechanism includes a turntable, a connecting column, a rotation drive cylinder and a rotation support; the movable support plate is a double-layer structure; the movable support plate includes an upper support plate and a lower support plate; the upper support plate and the lower support plate are connected and fixed by a support plate; the turntable is rotatably connected to the lower support plate through the rotation support; the turntable extends into a circular hole provided on the upper support plate, and the upper surface of the turntable is flush with the upper surface of the upper support plate; the connecting column is provided on the lower surface of the turntable at a position deviating from the rotation center; the end of the connecting column is rotatably connected to the cylinder rod of the rotation drive cylinder; the terminal end of the rotation drive cylinder is hinged to the lower support plate.

[0011] During operation, the controller controls the extension of the rotary drive cylinder through an electrical signal. Since the limit column offsets the movement distance of the rotation center of the turntable, the turntable rotates during the extension of the rotary drive cylinder. After the rotary drive cylinder is fully extended, the turntable rotates 90°, thereby driving the cable roller on it to adjust the angle.

[0012] Preferably, the angle adjustment mechanism also includes an axially movable unit; the axially movable unit includes a first movable plate, a second movable plate, a guide rod, a guide seat, an L-shaped connecting plate and a movable driving cylinder; a rectangular opening groove is provided on the turntable corresponding to the position of the centering mechanism; the first movable plate is provided in one opening groove, and the second movable plate is provided in the other opening groove; the first movable plate and the second movable plate are fixedly connected by two parallel guide rods; the guide rod is slidably connected to the lower surface of the turntable through the guide seat; the first movable plate is connected to the cylinder rod of the movable driving cylinder through the L-shaped connecting plate; the movable driving cylinder is fixedly connected to the turntable.

[0013] During operation, the controller controls the lifting mechanism to vertically feed the cable roller into the roller placement frame of the cable stranding machine. The controller then controls the movement of the driving cylinder through an electrical signal, thereby driving the first movable plate and the second movable plate used to support the cable roller to move, and then the cable roller on it is moved axially, so that the cable roller is pressed against the fixed tightening shaft on the roller placement frame, thereby avoiding the use of the movable tightening shaft on the roller placement frame to forcibly push the cable roller against the fixed tightening shaft. This not only increases the difficulty of the loading personnel to lock the movable tightening shaft, but also because the cable roller is heavy, the increased locking difficulty will also lead to an increased risk of incomplete locking, thereby increasing the risk of accidents. In this case, one end of the cable roller is first pressed against the fixed tightening shaft through the axial moving unit, and then only the movable tightening shaft needs to be locked against the other end of the cable roller. During the process, there is no need to drive the movement of the cable roller, thereby greatly reducing the labor intensity of the loading personnel and reducing the probability of the cable roller not being fully locked, thereby improving the safety of the operation of the power cable stranding machine.

[0014] Preferably, the centering mechanism includes a guide bar, a first spring and a support plate; the centering mechanism is a symmetrical structure; the guide bar is symmetrically arranged on both sides of the turntable; the support plate is arranged on the outer side of the guide bar; the support plate is fixedly connected to the turntable; a plurality of the first springs are evenly spaced between the guide bar and the support plate; the two ends of the first spring are respectively fixedly connected to the guide bar and the support plate.

[0015] During operation, the cable roller rolls between the two guide bars, thereby limiting its axial position. In this case, the compressible guide bar not only automatically aligns the cable roller through the elastic force of the first springs on both sides, but also consumes the kinetic energy of the rolling cable roller as it squeezes the first spring, thereby reducing the force exerted by the cable roller against the limit mechanism. This allows the cable roller to stop more stably when forced to do so by the limit mechanism, thereby improving the limiting accuracy of the limit mechanism and the safety of the loading device during the loading process. By absorbing kinetic energy through the guide bar and the first spring, the cable roller has a longer service life than using elastic rubber strips.

[0016] Preferably, the limit mechanism is symmetrically arranged on both sides of the turntable; the limit mechanism includes a swing lever, a second spring, a rotating block, a sliding block and a mounting support plate; the lower end of the swing lever is hinged on the support plate; a mounting support plate is provided on the outer side of the swing lever; the mounting support plate is fixedly connected to the support plate; a second spring is provided perpendicular to the direction of the mounting support plate; one end of the second spring is fixedly connected to the mounting support plate through a fixing column; the other end of the second spring is fixedly connected to the rotating block; the rotating block is hinged to the sliding block; the sliding surface of the sliding block is in contact with the swing lever; the swing lever and the second spring are perpendicular to each other; the limiting support column is fixedly connected to the mounting support plate; a distance is left between the protruding end of the limiting support column and the swing lever.

[0017] During operation, the cable roller is axially restricted by the centering mechanism and then hits the limit mechanism. The limit plates on both sides of the cable roller hit the swing rod, and then the swing rod positively squeezes the second spring. During the compression of the second spring, the angle of the swing rod relative to the second spring also changes. Since the swing rod does not squeeze the second spring vertically, the sliding block slides along the swing rod in the direction of the component force, thereby rapidly reducing the elastic supporting force of the second spring. At this time, the swing rod is only subjected to the rebound force of the bending of the second spring, and the rebound force is much smaller than the positive compression force. Therefore, in this case, the cable When the limit plates on both sides of the roller hit the swing arm, they obtain a large rebound force by positively compressing the second spring in the early stage, which quickly consumes the kinetic energy of the cable roller. In the later stage, after the angle of the swing arm relative to the second spring changes, the sliding block slides along the swing arm, so that the second spring only has a small rebound force generated by bending, so that the cable roller can slowly squeeze the swing arm to contact the limit support column, and the second spring will not be continuously squeezed to cause the stored rebound force to be too large, thereby not pushing the cable roller to roll in the opposite direction, thereby improving the limiting accuracy of the cable roller by the limiting mechanism.

[0018] Preferably, limiting structures are provided on both sides of the sliding block.

[0019] By setting a limiting structure on both sides of the sliding block, the sliding block is prevented from detaching from the swing rod when sliding along the swing rod, which causes the sliding block to be unable to return to the initial position, thereby causing the function of the limiting mechanism to fail, and the position of the cable roller cannot be guaranteed, and the loading device is unable to complete the subsequent automatic loading of the cable roller.

[0020] Preferably, the lifting mechanism includes a lower U-shaped groove rod, a lifting drive cylinder, a driving bracket, a first limiting wheel, a first scissors arm, a second scissors arm, an upper U-shaped groove rod, a second limiting wheel and a lifting support plate; the lifting support plate is arranged above the base; the lifting support plate is connected to the base through the first scissors arm and the second scissors arm hinged to each other in the middle; the upper end of the first scissors arm is hinged on the lifting support plate, and the lower end of the first scissors arm is rotatably connected to the end portion, and the first limiting wheel slides in the lower U-shaped groove rod; the lower U-shaped groove rod is fixedly connected to the base; the lower end of the second scissors arm is hinged to the base, and the upper end of the second scissors arm is rotatably connected to the end portion, and the second limiting wheel slides in the upper U-shaped groove rod; the upper U-shaped groove rod is fixedly connected to the lifting support plate; the lifting support plate is connected to the horizontal moving mechanism; the two ends of the driving bracket are respectively connected to the rotating shafts of the two first limiting wheels; the driving bracket is fixedly connected to the cylinder rod of the lifting driving cylinder; and the lifting driving cylinder is fixedly connected to the base.

[0021] A third limiting wheel is provided on each side of the driving bracket, thereby improving the smoothness of the movement of the driving bracket; when working, the controller drives the lifting driving cylinder to extend through an electrical signal, and then pushes the lower end of the first scissor arm closer to the lower end of the second scissor arm through the driving bracket. Since the angle between the first scissor arm and the second scissor arm is reduced, the support height of the upper ends of the first scissor arm and the second scissor arm is increased, thereby realizing the lifting of the horizontal transfer mechanism on the lifting support plate, that is, realizing the lifting of the cable roller.

[0022] Preferably, the horizontal transfer mechanism includes a transfer drive cylinder and a linear guide rail; the movable support plate is connected to the lifting support plate through the linear guide rail; one end of the movable support plate is fixedly connected to the cylinder rod of the transfer drive cylinder; the cylinder body of the transfer drive cylinder is fixedly connected to the lifting support plate.

[0023] During operation, the controller controls the transfer drive cylinder to extend through electrical signals, thereby sending the cable roller on the mobile support plate to the bottom of the roller placement frame of the cable stranding machine.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. In the present invention, the cable roller to be installed is rolled onto the movable support plate, and then pushed toward the centering mechanism on the angle adjustment mechanism. The axial position of the cable roller is limited by the centering mechanism, and the cable roller is continued to be rolled so that it hits the limiting mechanism. The limiting mechanism limits the position of the cable roller axis. Then, the controller controls the angle adjustment mechanism through electrical signals to carry the cable roller that has completed the position limit in the horizontal plane and rotates 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine; then, the controller controls the horizontal transfer mechanism through electrical signals to move the cable roller carried on the movable support plate to the cable stranding machine where the roller is placed. Directly below the rack, the controller controls the lifting mechanism through electrical signals to send the cable roller into the roller placement rack of the cable stranding machine in the vertical direction, and finally locks the movable tightening shaft on the roller placement rack for locking the cable roller, thereby realizing semi-automatic loading of the power cable stranding machine that is parked at a fixed point. In this case, the heavier cable roller is transported to the roller placement rack of the cable stranding machine through the loading device, and the centering mechanism and the limiting mechanism are used for positioning during the process, thereby improving the accuracy and efficiency of loading. The loading is carried out through the lifting mechanism, the horizontal transfer mechanism and the angle adjustment mechanism and is automatically controlled by the controller, thereby further improving the accuracy and efficiency of loading.

[0026] 2. In the present invention, the cable roller to be installed is rolled to the position of the alignment mechanism on the movable support plate, and the controller controls the first lifting cylinder and the second lifting cylinder to extend the cylinder rod at the same time through an electrical signal, and then the cable roller is lifted up by the first lifting roller frame and the second lifting roller frame. Since the first lifting roller frame and the second lifting roller frame are parallel to each other, the cable roller is lifted up and at the same time its own axis is aligned with the first lifting roller frame and the second lifting roller frame. Then the controller controls the push cylinder to pull the push plate through an electrical signal, and the push plate pushes the cable roller along the axis to the middle of the movable support plate to align, so that the axial position of the cable roller is aligned with the centering mechanism, and there is no need to manually adjust the angle and position of the cable roller to push it into the centering mechanism, thereby reducing the labor intensity of the loading personnel while improving the accuracy and efficiency of loading.

[0027] 3. In the present invention, the controller controls the lifting mechanism to vertically feed the cable roller into the roller placement frame of the cable stranding machine. The controller then controls the movement of the driving cylinder through an electrical signal to extend, thereby driving the first movable plate and the second movable plate for supporting the cable roller to move, and then the cable roller thereon is moved axially, so that the cable roller is pressed against the fixed tightening shaft on the roller placement frame, thereby avoiding the use of the movable tightening shaft on the roller placement frame to forcibly push the cable roller against the fixed tightening shaft, which not only increases the difficulty of the loading personnel to lock the movable tightening shaft, but also because the cable roller is heavy, the increased locking difficulty also leads to an increased risk of incomplete locking, thereby increasing the risk of accidents. In this case, one end of the cable roller is first pressed against the fixed tightening shaft through the axial moving unit, and then only the movable tightening shaft needs to be locked against the other end of the cable roller. During the process, there is no need to drive the movement of the cable roller, thereby greatly reducing the labor intensity of the loading personnel and reducing the probability of the cable roller being incompletely locked, thereby improving the safety of the operation of the power cable stranding machine.

[0028] 4. In the present invention, the cable roller is axially restricted by the centering mechanism and then hits the limiting mechanism. The limiting plates on both sides of the cable roller hit the swing rod, and then the swing rod positively squeezes the second spring. During the compression of the second spring, the angle of the swing rod relative to the second spring also changes. Since the swing rod does not squeeze the second spring vertically, the sliding block slides along the swing rod in the direction of the component force, and the elastic supporting force of the second spring is rapidly reduced. At this time, the swing rod is only subjected to the rebound force of the bending of the second spring. The rebound force is much smaller than the positive compression force. In this case, When the limit plates on both sides of the cable roller hit the swing arm, they initially obtain a large rebound force by positively compressing the second spring, which quickly consumes the kinetic energy of the cable roller. In the later stage, after the angle of the swing arm relative to the second spring changes, the sliding block slides along the swing arm, so that the second spring only has a small rebound force generated by bending, so that the cable roller can slowly squeeze the swing arm to contact the limit support column, and the second spring will not be continuously squeezed to cause the stored rebound force to be too large, thereby pushing the cable roller to roll in the opposite direction, thereby improving the limiting accuracy of the cable roller by the limiting mechanism.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0042] like Figures 1 to 4As shown, a fixed-point parking and loading device for a power cable stranding machine includes a base 1, a lifting mechanism 2, a horizontal transfer mechanism 3, a movable support plate 4, a centering mechanism 5, a limiting mechanism 6 and an angle adjustment mechanism 7; the base 1 is provided with the lifting mechanism 2 for driving the horizontal transfer mechanism 3 to lift up and down; the horizontal transfer mechanism 3 is used to drive the movable support plate 4 above to move horizontally; the angle adjustment mechanism 7 is provided at one end of the movable support plate 4; the angle adjustment mechanism 7 is used to adjust the angle of the cable roller thereon; the centering mechanism 5 and the limiting mechanism 6 are provided on the angle adjustment mechanism 7; the centering mechanism 5 is used to limit the axial position of the cable roller; the limiting mechanism 6 is used to limit the position of the axis of the cable roller.

[0043] During operation, the power cable stranding machine uses a fixed-point parking loading device to place the wire roller placement frame of the cable stranding machine. In the initial state, the lifting mechanism 2 is in the lowest position, and the horizontal transfer mechanism 3 is in a retracted state away from the cable stranding machine; the cable roller to be installed is rolled onto the movable support plate 4, and then pushed to the centering mechanism 5 on the angle adjustment mechanism 7. The axial position of the cable roller is limited by the centering mechanism 5, and the cable roller is continued to be rolled so that it contacts the limiting mechanism 6. The limiting mechanism 6 limits the position of the cable roller axis, and then the controller controls the angle adjustment mechanism 7 through an electrical signal to carry the cable roller that has completed the position limit in the horizontal plane to rotate 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine; then the controller controls the angle adjustment mechanism 7 through an electrical signal to carry the cable roller that has completed the position limit in the horizontal plane to rotate 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine; then the controller controls the angle adjustment mechanism 7 through an electrical signal to carry the cable roller that has completed the position limit in the horizontal plane to rotate 90°, so that the axis of the cable roller is consistent with the installation axis on the cable stranding machine The signal controls the horizontal transfer mechanism 3 to move the cable roller carried on the movable support plate 4 to the bottom of the roller placement rack of the cable stranding machine. The controller then controls the lifting mechanism 2 through an electrical signal to send the cable roller into the roller placement rack of the cable stranding machine in the vertical direction. Finally, the movable tightening shaft on the roller placement rack for locking the cable roller is locked, thereby realizing semi-automatic loading of the power cable stranding machine that is parked at a fixed point. In this case, the heavier cable roller is transported to the roller placement rack of the cable stranding machine through the loading device. The centering mechanism 5 and the limiting mechanism 6 are used for positioning during the process, thereby improving the accuracy and efficiency of loading. The loading is carried out by the lifting mechanism 2, the horizontal transfer mechanism 3 and the angle adjustment mechanism 7 and is automatically controlled by the controller, thereby further improving the accuracy and efficiency of loading.

[0044] like Figures 5 to 8As shown, the fixed-point parking and feeding device for the power cable stranding machine also includes an alignment mechanism 8; the alignment mechanism 8 is arranged on the other end of the mobile support plate 4; the alignment mechanism 8 includes a first lifting roller frame 81, a first lifting cylinder 82, a second lifting roller frame 83, a second lifting cylinder 84, a push plate 85 and a push cylinder 86; two strip grooves are arranged in parallel on the mobile support plate 4; the first lifting roller frame 81 and the second lifting roller frame 83 are respectively arranged in the strip grooves; the lower end of the first lifting roller frame 81 is connected to the first lifting cylinder The cylinder rod end of cylinder 82; the cylinder body of the first lifting cylinder 82 is fixedly connected to the movable support plate 4; the lower end of the second lifting roller frame 83 is connected to the cylinder rod end of the second lifting cylinder 84; the cylinder body of the second lifting cylinder 84 is fixedly connected to the movable support plate 4; a push-pull groove is provided on the movable support plate 4 between the two strip grooves; the push plate 85 is slidably connected in the push-pull groove; the lower end of the push plate 85 is fixedly connected to the cylinder rod end of the pushing cylinder 86; the pushing cylinder 86 is fixedly connected to the movable support plate 4.

[0045] During operation, the cable roller to be installed is rolled to the position of the alignment mechanism 8 on the movable support plate 4, and the controller controls the first lifting cylinder 82 and the second lifting cylinder 84 to extend the cylinder rod at the same time through electrical signals, and then lifts the cable roller through the first lifting roller frame 81 and the second lifting roller frame 83. Since the first lifting roller frame 81 and the second lifting roller frame 83 are parallel to each other, the cable roller is lifted up while its own axis is aligned with the first lifting roller frame 81 and the second lifting roller frame 83. Then the controller controls the push cylinder 86 to pull the push plate 85 through electrical signals, and the push plate 85 pushes the cable roller along the axis to the middle of the movable support plate 4 to align, so that the axial position of the cable roller is aligned with the centering mechanism 5, and there is no need to manually adjust the angle and position of the cable roller to push it into the centering mechanism 5, thereby reducing the labor intensity of the loading personnel while improving the accuracy and efficiency of loading. The push plate 85 and the pushing cylinder 86 can be set in one group on each side of the movable support plate 4, or in one group on only one side; if only one group is set, when the cable roller is placed on the movable support plate 4, the cable roller needs to be placed close to that side, so that the push plate 85 can adjust the cable roller within the effective stroke.

[0046] like Figure 3As shown, the first lifting cylinder 82 and the second lifting cylinder 84 are each independently connected to the controller via electrical signals; after the alignment mechanism 8 aligns the cable roller with the centering mechanism 5, the controller independently controls the retraction of the second lifting cylinder 84 near the centering mechanism 5. Because the first lifting cylinder 82 is still in the extended state at this time, the cable roller rolls toward the centering mechanism 5 under the action of its own weight after the second lifting cylinder 84 retracts. Therefore, there is no need to manually push the cable roller to roll toward the centering mechanism 5, thereby reducing the labor intensity of the loading personnel. By providing a back pressure valve in the retraction air path of the second lifting cylinder 84, the speed of the cylinder rod of the second lifting cylinder 84 is controlled, and the rolling speed of the cable roller is controlled, thereby controlling the impact force of the cable roller rolling onto the centering mechanism 5 and the limiting mechanism 6.

[0047] like Figures 5 to 7 As shown, the angle adjustment mechanism 7 includes a turntable 71, a connecting column 72, a rotation drive cylinder 73 and a rotation support 74; the movable support plate 4 is a double-layer structure; the movable support plate 4 includes an upper support plate 41 and a lower support plate 42; the upper support plate 41 and the lower support plate 42 are connected and fixed by a support plate 53; the turntable 71 is rotatably connected to the lower support plate 42 through the rotation support 74; the turntable 71 extends into the circular hole provided on the upper support plate 41, and the upper surface of the turntable 71 is flush with the upper surface of the upper support plate 41; the connecting column 72 is provided on the lower surface of the turntable 71 at a position deviating from the rotation center; the end of the connecting column 72 is rotatably connected to the cylinder rod of the rotation drive cylinder 73; the terminal end of the rotation drive cylinder 73 is hinged to the lower support plate 42.

[0048] During operation, the controller controls the extension of the rotation drive cylinder 73 through an electrical signal. Since the limit column offsets the movement distance of the rotation center of the turntable 71, the turntable 71 rotates during the extension of the rotation drive cylinder 73. After the rotation drive cylinder 73 is fully extended, the turntable 71 rotates 90°, thereby driving the cable roller thereon to adjust the angle.

[0049] like Figures 5 to 7As shown, the angle adjustment mechanism 7 also includes an axial moving unit 75; the axial moving unit 75 includes a first moving plate 751, a second moving plate 752, a guide rod 753, a guide seat 754, an L-shaped connecting plate 755 and a moving drive cylinder 756; a rectangular opening groove is set on the turntable 71 corresponding to the position of the centering mechanism 5; the first moving plate 751 is set in one opening groove, and the second moving plate 752 is set in the other opening groove; the first moving plate 751 and the second moving plate 752 are fixedly connected by two parallel guide rods 753; the guide rod 753 is slidably connected to the lower surface of the turntable 71 through the guide seat 754; the first moving plate 751 is connected to the cylinder rod of the moving drive cylinder 756 through the L-shaped connecting plate 755; the moving drive cylinder 756 is fixedly connected to the turntable 71.

[0050] During operation, the controller controls the lifting mechanism 2 to send the cable roller into the roller placement frame of the cable twisting machine in the vertical direction, and then the controller controls the mobile drive cylinder 756 to extend through an electrical signal, thereby driving the first movable plate 751 and the second movable plate 752 for carrying the cable roller to move, and then moving the cable roller thereon axially, so that the cable roller is pressed against the fixed tightening shaft on the roller placement frame, thereby avoiding the forced pushing of the cable roller against the fixed tightening shaft by the movable tightening shaft on the roller placement frame, which not only increases the difficulty of the loading personnel to lock the movable tightening shaft, but also because the cable roller is heavy, the increased locking difficulty will also lead to an increased risk of incomplete locking, thereby increasing the risk of accidents. In this case, one end of the cable roller is first pressed against the fixed tightening shaft through the axial moving unit 75, and then the movable tightening shaft needs to be locked and pressed against the other end of the cable roller. During the process, there is no need to drive the movement of the cable roller, which greatly reduces the labor intensity of the loading personnel and the probability of the cable roller not being completely locked, thereby improving the safety of the operation of the power cable stranding machine.

[0051] like Figures 9 and 10 As shown, the centering mechanism 5 includes a guide bar 51, a first spring 52 and a support plate 53; the centering mechanism 5 is a symmetrical structure; the guide bar 51 is symmetrically arranged on both sides of the turntable 71; the support plate 53 is arranged on the outer side of the guide bar 51; the support plate 53 is fixedly connected to the turntable 71; a plurality of first springs 52 are evenly spaced between the guide bar 51 and the support plate 53; the two ends of the first spring 52 are respectively fixedly connected to the guide bar 51 and the support plate 53.

[0052] During operation, the cable roller rolls between the two guide bars 51 to limit the axial position of the cable roller. In this case, the compressible guide bar 51 is not only automatically centered by the elastic force of the first springs 52 on both sides, but also consumes the kinetic energy of the rolling cable roller in the process of the cable roller squeezing the first spring 52, thereby reducing the force of the cable roller impacting the limit mechanism 6. As a result, the cable roller is more stably stopped when forced to stop by the limit mechanism 6, thereby improving the limiting accuracy of the limit mechanism 6 and also improving the safety of the loading device during the loading process. By absorbing kinetic energy through the guide bar 51 and the first spring 52, the service life is longer than that of using elastic rubber strips.

[0053] like Figures 9 and 10 As shown, the limit mechanism 6 is symmetrically arranged on both sides of the turntable 71; the limit mechanism 6 includes a swing rod 61, a second spring 62, a rotating block 63, a sliding block 64 and a mounting support plate 65; the lower end of the swing rod 61 is hinged on the support plate 53; a mounting support plate 65 is provided on the outer side of the swing rod 61; the mounting support plate 65 is fixedly connected to the support plate 53; a second spring 62 is provided in a direction perpendicular to the mounting support plate 65; one end of the second spring 62 is fixedly connected to the mounting support plate 65 through a fixing column; the other end of the second spring 62 is fixedly connected to the rotating block 63; the rotating block 63 is hinged to the sliding block 64; the sliding surface of the sliding block 64 contacts the swing rod 61; the swing rod 61 and the second spring 62 are perpendicular to each other; a limiting support column 66 is fixedly connected to the mounting support plate 65; a distance is left between the protruding end of the limiting support column 66 and the swing rod 61.

[0054] During operation, the cable roller is axially restricted by the centering mechanism 5 and then hits the limiting mechanism 6. The limiting plates on both sides of the cable roller hit the swing rod 61, and then the swing rod 61 positively squeezes the second spring 62. During the compression of the second spring 62, the angle of the swing rod 61 relative to the second spring 62 also changes. Since the swing rod 61 does not squeeze the second spring 62 vertically, the sliding block 64 slides along the swing rod 61 in the direction of the component force, thereby rapidly reducing the elastic supporting force of the second spring 62. At this time, the swing rod 61 is only subjected to the rebound force of the bending of the second spring 62, which is much smaller than the positively compressed force. In this case, The limiting plates on both sides of the cable roller hit the swing rod 61 and initially obtain a large rebound force by positively compressing the second spring 62, thereby quickly consuming the kinetic energy of the cable roller. In the later stage, after the angle of the swing rod 61 relative to the second spring 62 changes, the sliding block 64 slides along the swing rod 61, so that the second spring 62 only has a small rebound force generated by bending, so that the cable roller can slowly squeeze the swing rod 61 to contact the limiting support column 66, and the second spring 62 will not be continuously squeezed to cause the stored rebound force to be too large, thereby not pushing the cable roller to roll in the opposite direction, thereby improving the limiting accuracy of the limiting mechanism 6 on the cable roller.

[0055] like Figures 9 and 10 As shown, limiting structures are provided on both sides of the sliding block 64 .

[0056] By setting a limiting structure on both sides of the sliding block 64, the sliding block 64 is prevented from detaching from the swing rod 61 when sliding along the swing rod 61, which causes the sliding block 64 to be unable to return to the initial position, thereby causing the function of the limiting mechanism 6 to fail, and the position of the cable roller cannot be guaranteed, and the loading device is unable to complete the subsequent automatic loading of the cable roller.

[0057] like Figure 2 and Figure 4As shown, the lifting mechanism 2 includes a lower U-shaped groove rod 21, a lifting drive cylinder 22, a driving bracket 23, a first limiting wheel 24, a first scissor arm 25, a second scissor arm 26, an upper U-shaped groove rod 27, a second limiting wheel 28 and a lifting support plate 29; the lifting support plate 29 is arranged above the base 1; the lifting support plate 29 is connected to the base 1 through the first scissor arm 25 and the second scissor arm 26 hinged to each other in the middle; the upper end of the first scissor arm 25 is hinged on the lifting support plate 29, and the lower end of the first scissor arm 25 slides in the lower U-shaped groove rod 21 through the first limiting wheel 24 rotatably connected at the end. movement; the lower U-shaped groove rod 21 is fixedly connected to the base 1; the lower end of the second scissor arm 26 is hinged on the base 1, and the upper end of the second scissor arm 26 slides in the upper U-shaped groove rod 27 through the second limiting wheel 28 connected by end rotation; the upper U-shaped groove rod 27 is fixedly connected to the lifting support plate 29; the lifting support plate 29 is connected to the horizontal transfer mechanism 3; the two ends of the driving bracket 23 are respectively connected to the rotating shafts of the two first limiting wheels 24; the driving bracket 23 is fixedly connected to the cylinder rod of the lifting driving cylinder 22; the lifting driving cylinder 22 is fixedly connected to the base 1.

[0058] A third limiting wheel is provided on each side of the driving bracket 23, thereby improving the smoothness of the movement of the driving bracket 23; during operation, the controller drives the lifting driving cylinder 22 to extend through an electrical signal, and then pushes the lower end of the first scissor arm 25 toward the lower end of the second scissor arm 26 through the driving bracket 23. Since the angle between the first scissor arm 25 and the second scissor arm 26 is reduced, the support height of the upper ends of the first scissor arm 25 and the second scissor arm 26 is increased, thereby realizing the lifting of the horizontal transfer mechanism 3 on the lifting support plate 29, that is, realizing the lifting of the cable roller.

[0059] like Figure 2 and Figure 4 As shown, the horizontal transfer mechanism 3 includes a transfer drive cylinder 31 and a linear guide rail 32; the movable support plate 4 is connected to the lifting support plate 29 through the linear guide rail 32; one end of the movable support plate 4 is fixedly connected to the cylinder rod of the transfer drive cylinder 31; the cylinder body of the transfer drive cylinder 31 is fixedly connected to the lifting support plate 29.

[0060] During operation, the controller controls the transfer drive cylinder 31 to extend through an electrical signal, thereby delivering the cable roller on the movable support plate 4 to the bottom of the roller placement frame of the cable stranding machine.
