Description
Technical Field
[0001] This invention relates to the field of anti-lift control technology, specifically to an electronically controlled anti-lift automatic control device. Background Technology
[0002] The electronically controlled anti-lifting automatic control device is an automated device that combines electronic control technology to prevent illegal or accidental lifting / opening. It is commonly found in equipment such as elevators, lifting platforms, smart locks, and industrial valves. Its core working principle is based on a closed-loop control system of sensor monitoring + control unit judgment + actuator action, ensuring that the equipment is only allowed to be lifted or started when safety conditions are met.
[0003] When staff perform equipment maintenance, troubleshooting, component replacement, or upgrades, they may disconnect the main cable harness of the servo driver. When reconnecting, the main cable harness bends at the same location each time, which significantly accelerates the mechanical fatigue of the cable at that point. This may lead to conductor breakage, insulation cracking, or shielding failure, resulting in signal interference, poor contact, interference with STO signals, and malfunctions. To address these issues, the following solutions are proposed. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides an electrically controlled anti-lift automatic control device, including a servo driver, an STO terminal fixedly disposed on the side wall of the servo driver, a main wiring harness fixedly disposed on the side wall of the servo driver, and further comprising:
[0005] The stop mechanism is slidably installed on the inner wall of the servo drive;
[0006] The braking mechanism is slidably mounted on the inner wall of the stop mechanism;
[0007] The follower mechanism is slidably mounted on the outer wall of the servo driver.
[0008] Preferably, the stop mechanism includes:
[0009] The force-applying component is slidably disposed on the inner wall of the servo driver;
[0010] The force-bearing component is fixedly installed on the inner wall of the force-applying component;
[0011] During the insertion process, the outer wall of the main wire harness comes into contact with the force-applying component, and when the force-applying component moves, the force-receiving component is subjected to a thrust.
[0012] Preferably, the braking mechanism includes:
[0013] The control component is slidably disposed on the inner wall of the force-applying component;
[0014] A protective component is slidably disposed on the inner wall of the force-applying component;
[0015] When the force-applying component moves, the protection component moves accordingly.
[0016] Preferably, the follower mechanism includes:
[0017] A tilting component is slidably mounted on the outer wall of the servo drive.
[0018] A limiting component is provided, which is installed on the inner wall of the protective component.
[0019] When the protection component moves, it generates a thrust on the limiting component, causing the limiting component to move as well.
[0020] Preferably, the force-applying component includes a restraint rod slidably connected to the inner wall of the servo drive, a fixed column fixedly connected to the inner wall of the servo drive, a movable block fixedly connected to the right end of the outer wall of the restraint rod, and a rotating block rotatably connected to the end of the movable block away from the restraint rod.
[0021] During the insertion process, the main wire harness is first placed on the top of the outer wall of the restraint rod, and then a pulling force is applied to the main wire harness to generate a pushing force on the moving block. The rotating block moves synchronously with the moving block.
[0022] Preferably, the force-bearing component includes a fixed rod fixedly connected to the inner wall of the fixed column, and a force-bearing block fixedly connected to the inner wall of the fixed column;
[0023] When the moving block and rotating block are moved by force, they move along the side wall of the fixed rod, and the liquid inside the fixed column is pushed, which applies a thrust to the force-bearing block.
[0024] Preferably, the control component includes a spring sheet fixedly connected to the inner wall of the rotating block, and an inclined block is fixedly connected to one end of the spring sheet near the fixed rod;
[0025] During the process of the rotating block moving towards one end of the force-bearing block under force, the spring and the inclined block move synchronously. At this time, the inclined block contacts the thread on the outer wall of the fixed rod with its inclined surface. When the main wire harness is pulled out, the inclined block contacts the thread surface of the fixed rod with its right-angled surface, so that the rotating block rotates during the movement. When the liquid passes through the circular groove on the surface of the moving block and the rotating block, the flow rate changes continuously. At the initial movement, the rotating block does not rotate, and the liquid flow rate is equal.
[0026] Preferably, the protection component includes a force-applying rod slidably connected to the top of the inner wall of the restraint rod, a drive rod rotatably connected to the top of the outer wall of the force-applying rod, a swing plate rotatably connected to the end of the drive rod near the restraint rod, and several protection plates slidably connected to the outer wall of the servo drive.
[0027] When the restraint rod moves, it drives the force application rod to move synchronously. During the movement of the force application rod, it generates a thrust on several protective plates. The shortest protective plate is the first. With the push of the swing plate, the protruding surfaces of several protective plates gradually increase and fit into the surface of the main wire harness.
[0028] Preferably, the tilting assembly includes a movable plate slidably connected to the outer wall of the servo drive, a passive plate rotatably connected to the side wall of the movable plate, a ball slidably connected to the bottom of the inner wall of the passive plate, and a telescopic rod fixedly connected to the bottom of the outer wall of the ball.
[0029] When the swing plate rotates, it generates a thrust on the moving plate. During the movement, the telescopic rod contacts the inclined surface of the outer wall of the servo driver. As the passive plate continues to move, the telescopic rod is subjected to force and moves along the inclined surface of the outer wall of the servo driver, causing the passive plate to rotate.
[0030] Preferably, the limiting component includes a limiting block slidably connected to the top of the inner wall of the force-applying rod, a spring piece 1 fixedly connected to the side wall of the limiting block, and a spring piece 2 fixedly connected to the end of the force-applying rod near the restraining rod;
[0031] When the protective plate contacts the surface of the main wiring harness, the force bar moves inside the restraint bar. During the movement, the limiting block is ejected outward by the elastic force of the spring piece one.
[0032] The present invention has the following beneficial effects:
[0033] (1) When the present invention is plugged in, a pulling force is generated on the binding rod, which forces the moving block to move and the rotating block to move synchronously. At this time, the liquid inside the fixed column is pushed. When the main wire harness is pulled out, the moving block and the rotating block move to the left. At this time, the inclined block contacts the threaded surface of the fixed rod with a right angle surface. During the movement, the rotating block rotates. During the reset process, the flow rate of the liquid changes continuously when it passes through the circular groove on the surface of the moving block and the rotating block. When the moving block and the rotating block move initially, the rotating block does not rotate, which causes the resistance of the binding rod to change during the reset process. Through the above components, the bending position of the main wire harness is different after each plugging, thereby effectively dispersing mechanical stress, delaying cable fatigue, and improving signal stability.
[0034] (2) When the binding rod moves, the present invention drives the force-applying rod to move synchronously. During the movement of the force-applying rod, a pulling force is generated on the driving rod, causing the driving rod to move under force. The driving rod drives the swing plate to rotate. During the rotation of the swing plate, a pushing force is generated on several protective plates, forcing several protective plates to move. Since the lengths of the several protective plates are different, with the shortest protective plate as the first, the protruding surfaces of several protective plates gradually increase during the push of the swing plate and fit with the surface of the main wire harness. By increasing the bending angle of the main wire harness (i.e., increasing the bending radius) through the above components, mechanical stress can be effectively reduced and fatigue of the main wire harness can be delayed.
[0035] (3) When the swing plate rotates, the present invention generates a thrust on the moving plate, causing the moving plate to move under force, and the passive plate moves accordingly. During the movement of the passive plate, a tension is generated on the telescopic rod, forcing the telescopic rod to be stretched. During the movement, the telescopic rod contacts the outer wall slope of the servo driver. As the passive plate continues to move, the telescopic rod moves along the outer wall slope of the servo driver under force. At this time, the ball slides inside the passive plate and generates a tension on the passive plate, causing the passive plate to rotate. By increasing the angle formed between the outermost edge of the protection plate and the surface of the main wire harness through the above components, the pressure on the surface of the main wire harness is relieved by expansion, thereby enhancing the protection of the main wire harness.
[0036] (4) During the movement of the force bar, when the protective plate contacts the surface of the main wire harness, it is resisted by the main wire harness. At this time, the force bar generates a pushing force on the second spring, forcing the second spring to be compressed and accumulating potential energy. The force bar moves inside the restraint bar. During the movement, the limiting block moves synchronously with the first spring. When the second spring is fully compressed, the limiting block pops outward through the elastic force of the first spring and is located above the surface of the main wire harness. Through the above components, the main wire harness is automatically restrained during the process of the main wire harness contacting the restraint bar and pulling the main wire harness.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0053] Example 1, please refer to Figures 1-8 This invention is an electrically controlled anti-lifting automatic control device, including a servo driver 13, an STO terminal 14 fixedly disposed on the side wall of the servo driver 13, a main wiring harness 15 fixedly disposed on the side wall of the servo driver 13, and further including:
[0054] The stop mechanism 1 is slidably disposed on the inner wall of the servo drive 13;
[0055] Braking mechanism 2 is slidably disposed on the inner wall of the stop mechanism 1;
[0056] Follower mechanism 3 is slidably disposed on the outer wall of servo driver 13.
[0057] The following are included in the following stop mechanism 1:
[0058] Force application component 11 is slidably disposed on the inner wall of servo driver 13;
[0059] Force-receiving component 12 is fixedly installed on the inner wall of force-applying component 11;
[0060] In the automated production line, when the safety door is not closed, the safety fence is not closed, or the equipment is not in a safe position, the sensor sends a signal to the safety controller. At this time, the safety controller sends a signal to the STO terminal 14 on the outer wall of the servo drive 13. If the safety is not met, the STO terminal 14 will disconnect. During installation, the operator vertically installs the servo drive 13 in a closed metal control cabinet and installs the STO terminal 14 on the outer wall of the servo drive 13. At this time, the operator plugs in the main wiring harness 15. When plugging in, the outer wall of the main wiring harness 15 contacts the force application component 11, and by pulling the main wiring harness 15, the force application component 11 is moved. When the force application component 11 moves, the force receiving component 12 is pushed.
[0061] Braking mechanism 2 includes:
[0062] Control component 21 is slidably disposed on the inner wall of force application component 11;
[0063] The protective component 22 is slidably disposed on the inner wall of the force-applying component 11;
[0064] When the force-applying component 11 moves, the control component 21 is resisted and moves, while the protection component 22 moves with the force-applying component 11.
[0065] The follower mechanism 3 includes:
[0066] The tilting component 31 is slidably disposed on the outer wall of the servo driver 13.
[0067] The limiting component 32 is slidably disposed on the inner wall of the protective component 22;
[0068] When the protection component 22 moves, it generates a thrust on the tilting component 31, forcing the tilting component 31 to move. At the same time, when the protection component 22 moves a certain distance, it generates a thrust on the limiting component 32, causing the limiting component 32 to move.
[0069] Example 2, please refer to Figures 3-12 The present invention is an electronically controlled anti-lifting automatic control device. Based on Example 1, the force application component 11 includes a restraining rod 111 slidably connected to the inner wall of the servo driver 13, a fixed column 112 fixedly connected to the inner wall of the servo driver 13, a moving block 113 fixedly connected to the right end of the outer wall of the restraining rod 111, and a rotating block 114 rotatably connected to the end of the moving block 113 away from the restraining rod 111.
[0070] The operator vertically installs the servo drive 13 in a closed metal control cabinet and installs the STO terminal 14 on the outer wall of the servo drive 13. At this time, the operator plugs in the main wiring harness 15. When plugging in, the operator first places the main wiring harness 15 on the top of the outer wall of the restraint rod 111, and then applies a pulling force to the main wiring harness 15 to plug it into the side wall of the servo drive 13. During the pulling process, the main wiring harness 15 generates a pulling force on the restraint rod 111, causing the restraint rod 111 to move. During the movement, a pushing force is generated on the moving block 113, forcing the moving block 113 to move. At the same time, the right end of the outer wall of the restraint rod 111 gradually enters the interior of the fixed column 112, and the rotating block 114 moves synchronously with the moving block 113.
[0071] The force-bearing component 12 includes a fixed rod 121 fixedly connected to the inner wall of the fixed column 112, and a force-bearing block 122 fixedly connected to the inner wall of the fixed column 112;
[0072] When the moving block 113 and the rotating block 114 are moved by force, they move along the side wall of the fixed rod 121. As the binding rod 111 continues to move, the left end of the outer wall of the fixed rod 121 gradually enters the interior of the binding rod 111. At this time, the liquid inside the fixed column 112 is pushed, which applies a pushing force to the force block 122, causing the force block 122 to move and generate a pushing force on the spring at the outer wall of the force block 122.
[0073] The control component 21 includes a spring piece 211 fixedly connected to the inner wall of the rotating block 114, and an inclined block 212 fixedly connected to one end of the spring piece 211 near the fixed rod 121;
[0074] During the process of rotating block 114 moving towards one end of force-bearing block 122 under force, it drives spring piece 211 and inclined block 212 to move synchronously. At this time, inclined block 212 makes threaded contact with the outer wall of fixed rod 121 with its inclined surface, and the fixed rod 121 generates a pushing force on inclined block 212, causing inclined block 212 to move under force. During the movement, pressure is applied to spring piece 211, forcing spring piece 211 to be compressed and accumulating potential energy. When the staff performs equipment maintenance or troubleshooting, it is necessary to unplug the main wire harness 15. At the same time as the main wire harness 15 is unplugged, the main wire harness 15 again generates a pulling force on the restraint rod 111. During the pulling process, moving block 113 and rotating block 114 move to the left. At this time, inclined block 212 moves in a straight line. The angled surface contacts the threaded surface of the fixed rod 121, causing the inclined block 212 to rotate on the outer wall of the fixed rod 121 during the movement. Simultaneously, this rotation drives the rotating block 114 to rotate. During this rotation, several circular grooves on the surface of the rotating block 114 rotate synchronously. This causes the flow rate of liquid through the circular grooves on the surfaces of the moving block 113 and the rotating block 114 to continuously change during the resetting process. Initially, the rotating block 114 does not rotate, and the liquid flow rate is equal. This results in a change in the resistance of the binding rod 111 to the liquid during the resetting process, ultimately causing the resetting position to differ from the initial position.
[0075] The protective component 22 includes a force-applying rod 221 that is slidably connected to the top of the inner wall of the restraint rod 111, a driving rod 222 that is rotatably connected to the top of the outer wall of the force-applying rod 221, a swing plate 223 that is rotatably connected to one end of the driving rod 222 near the restraint rod 111, and several protective plates 224 that are slidably connected to the outer wall of the servo driver 13.
[0076] When the restraint rod 111 moves, it drives the force application rod 221 to move synchronously. During the movement of the force application rod 221, it generates a pulling force on the driving rod 222, causing the driving rod 222 to move under the force. The driving rod 222 then drives the swing plate 223 to rotate. During the rotation of the swing plate 223, it generates a pushing force on several protective plates 224, forcing the protective plates 224 to move. Since the lengths of the protective plates 224 are different, with the shortest protective plate 224 as the first, the protruding surfaces of the protective plates 224 gradually increase and come into contact with the surface of the main wire harness 15 as the swing plate 223 pushes them. When the pushing force of the swing plate 223 is lost, the protective plates 224 lose their supporting force on the main wire harness 15. Under the elasticity of the main wire harness 15, they gradually move towards the swing plate 223. When they stop, their positions are different.
[0077] The tilting assembly 31 includes a movable plate 311 slidably connected to the outer wall of the servo drive 13, a passive plate 312 rotatably connected to the side wall of the movable plate 311, a ball 313 slidably connected to the bottom of the inner wall of the passive plate 312, and a telescopic rod 314 fixedly connected to the bottom of the outer wall of the ball 313.
[0078] When the swing plate 223 rotates, it generates a pushing force on the moving plate 311, causing the moving plate 311 to move under the force. The passive plate 312 moves along with it. During the movement of the passive plate 312, it generates a pulling force on the telescopic rod 314, forcing the telescopic rod 314 to be stretched. During the movement, the telescopic rod 314 contacts the outer wall inclined surface of the servo driver 13. As the passive plate 312 continues to move, the telescopic rod 314 moves along the outer wall inclined surface of the servo driver 13 under the force. At this time, the ball 313 slides inside the passive plate 312 and generates a pulling force on the passive plate 312, causing the passive plate 312 to rotate.
[0079] The limiting component 32 includes a limiting block 321 that is slidably connected to the top of the inner wall of the force-applying rod 221. A spring piece 322 is fixedly connected to the side wall of the limiting block 321. A spring piece 323 is fixedly connected to one end of the force-applying rod 221 near the restraint rod 111.
[0080] During the movement of the force-applying rod 221, the swing plate 223 rotates synchronously and drives several protective plates 224 to move. When the protective plate 224 contacts the surface of the main wire harness 15, it is resisted by the main wire harness 15. At this time, the force-applying rod 221 exerts a pushing force on the second spring 323, forcing the second spring 323 to be compressed and accumulate potential energy. The force-applying rod 221 moves inside the restraint rod 111. During the movement, the limiting block 321 moves synchronously with the first spring 322. When the second spring 323 is fully compressed, the limiting block 321 is ejected outward by the elastic force of the first spring 322 and is located above the surface of the main wire harness 15.
[0081] One specific application of this embodiment is as follows: In an automated production line, when the protective door (safety door) is not closed, the safety fence is not closed, or the equipment is not in a safe position, the sensor sends a signal to the safety controller. At this time, the safety controller sends a signal to the STO terminal 14 on the outer wall of the servo drive 13. If the safety is not met, the STO terminal 14 will be disconnected. During installation, the worker vertically installs the servo drive 13 in a closed metal control cabinet and installs the STO terminal 14 on the outer wall of the servo drive 13. At this time, the worker plugs in the main wiring harness 15.
[0082] When staff unplug the main cable harness 15 during equipment maintenance, troubleshooting, component replacement, or upgrades, the bends in the main cable harness 15 are always at the same location during reconnection. This significantly accelerates mechanical fatigue of the cable at that point, potentially leading to conductor breakage, insulation cracking, or shielding failure. This can cause signal interference, poor contact, interference with STO signals, and malfunctions. To address this, during reconnection, the main cable harness 15 should first be placed on the top of the outer wall of the restraint rod 111. Then, a pulling force should be applied to the main cable harness 15 to insert it into the side wall of the servo drive 13. During this pulling process, the main cable harness 15 exerts a pulling force on the restraint rod 111, causing the restraint rod 111 to move. This movement generates force on the moving block 113. The thrust forces the moving block 113 to move, while the right end of the outer wall of the restraining rod 111 gradually enters the interior of the fixed column 112. The rotating block 114 moves synchronously with the moving block 113. When the moving block 113 and the rotating block 114 are moved by the force, they move along the side wall of the fixed rod 121. As the restraining rod 111 continues to move, the left end of the outer wall of the fixed rod 121 gradually enters the interior of the restraining rod 111. At this time, the liquid inside the fixed column 112 is thrust, which applies a thrust to the force-bearing block 122, causing the force-bearing block 122 to move and generating a thrust on the spring at the outer wall of the force-bearing block 122. As the rotating block 114 moves towards the force-bearing block 122 under the force, it drives the spring piece 211 and the inclined block 212 to move synchronously. The inclined block 212 contacts the threaded surface of the fixed rod 121 with its inclined surface, and the fixed rod 121 exerts a pushing force on the inclined block 212, causing the inclined block 212 to move under the force. During the movement, pressure is applied to the spring piece 211, forcing the spring piece 211 to be compressed and accumulating potential energy. When the staff performs equipment maintenance or troubleshooting, the main wire harness 15 needs to be unplugged. At the same time as the main wire harness 15 is unplugged, the main wire harness 15 again exerts a pulling force on the restraining rod 111. During the pulling process, the moving block 113 and the rotating block 114 move to the left. At this time, the inclined block 212 contacts the threaded surface of the fixed rod 121 with its right-angled surface, causing the inclined block 212 to rotate at the outer wall of the fixed rod 121 during the movement. At the same time as the rotation, the rotating block 114 is driven to rotate. During rotation, several circular grooves on the surface of the rotating block 114 rotate synchronously, causing the flow rate of liquid through the circular grooves on the surfaces of the moving block 113 and the rotating block 114 to change continuously during the reset process. When the moving block 113 and the rotating block 114 initially move, the rotating block 114 does not rotate, and the liquid flow rate is equal at this time. This causes the resistance of the binding rod 111 to change during the reset process, and the final reset position changes from the initial position. Through the above components, the bending position of the main wire harness 15 is different after each insertion, thereby effectively dispersing mechanical stress, delaying cable fatigue, significantly improving service life and system reliability, and improving signal stability.
[0083] Utilizing the movement characteristics of the aforementioned restraint rod 111, the restraint rod 111 moves, driving the force-applying rod 221 to move synchronously. During the movement of the force-applying rod 221, a pulling force is generated on the driving rod 222, causing the driving rod 222 to move under the force. This movement, in turn, causes the swing plate 223 to rotate. During the rotation of the swing plate 223, a pushing force is generated on several protective plates 224, forcing them to move. Since the lengths of the protective plates 224 are different, with the shortest protective plate 224 leading, the protruding surfaces of the protective plates 224 gradually increase as they are pushed by the swing plate 223, eventually reaching the surface of the main wire harness 15. In terms of fit, if the main wire harness 15 is kept at too small a bending angle when it is not plugged in for a long time, it may cause permanent deformation of the internal structure of the main wire harness 15, cracking of the insulation layer, and breakage of the conductor, which will affect the electrical performance and safety reliability during subsequent use. By increasing the bending angle of the main wire harness 15 (i.e., increasing the bending radius) by the above-mentioned components, mechanical stress can be effectively reduced, fatigue of the main wire harness 15 can be delayed, and the stability and service life of the electrical connection can be significantly improved. When the thrust of the swing plate 223 is lost, the protection plate 224 loses its support force on the main wire harness 15. Under the elasticity of the main wire harness 15, it gradually moves towards the swing plate 223. When it stops, its position is different.
[0084] Utilizing the oscillating characteristics of the aforementioned swing plate 223, when the swing plate 223 rotates, it generates a pushing force on the moving plate 311, causing the moving plate 311 to move under the force. The passive plate 312 follows suit. During the movement of the passive plate 312, it generates a pulling force on the telescopic rod 314, forcing the telescopic rod 314 to be stretched. During the movement, the telescopic rod 314 contacts the inclined surface of the outer wall of the servo driver 13. As the passive plate 312 continues to move, the telescopic rod 314 moves along the inclined surface of the outer wall of the servo driver 13 under the force. At this time, the sphere 3... 13 Slides inside the passive plate 312 and exerts a pulling force on the passive plate 312, causing the passive plate 312 to rotate. Since the outermost of several protective plates 224 still forms a small angle with the outer wall of the main wire harness 15 when the bending angle of the main wire harness 15 is increased, damage to the surface of the main wire harness 15 still exists under the support of the protective plates 224. By increasing the angle formed between the outermost of the protective plates 224 and the surface of the main wire harness 15 through the above-mentioned components, the pressure on the surface of the main wire harness 15 is relieved by expansion, thereby enhancing the protection of the main wire harness 15.
[0085] Utilizing the characteristics of the movement of the aforementioned force-applying rod 221, during the movement of the force-applying rod 221, the swing plate 223 rotates synchronously, driving several protective plates 224 to move. When the protective plate 224 contacts the surface of the main wire harness 15, it is resisted by the main wire harness 15. At this time, the force-applying rod 221 generates a pushing force on the second spring 323, forcing the second spring 323 to be compressed and accumulating potential energy. The force-applying rod 221 moves inside the restraint rod 111. During the movement, the limiting block 321 and the first spring 322 move synchronously. When the second spring 323 is fully compressed, the limiting block 321 moves through the first spring 322... The elastic force of component 2 causes it to pop outward and position itself above the surface of the main wire harness 15. Since the main wire harness 15 is fixed for a long time, if the main wire harness 15 detaches from the restraint rod 111 at this time, it will lose the protection of the bending point of the main wire harness 15, resulting in a smaller bending angle. This causes the main wire harness 15 to bear higher stress during frequent movement, and the copper wire inside the conductor is prone to micro-fractures that gradually expand, eventually leading to signal interruption or power failure. Through the above-mentioned components, the main wire harness 15 is automatically restricted during the process of contacting the restraint rod 111 and pulling the main wire harness 15, preventing deviation during subsequent device vibration.
