Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology in the stage performance industry, and in particular to a cable drag chain support device and method for unpowered adaptive horizontal linear movement. Background Technology

[0002] There are three main existing support methods for long-stroke cable drag chains: ① Battery-powered, eliminating the drag chain, but battery capacity limits the stroke and requires frequent maintenance; ② Ordinary drag chains are towed by the equipment, and over medium to long distances, the upper chain segments sag due to their own weight, rubbing against the lower segments, generating noise and premature wear; ③ Wheeled drag chains, although with added roller support, wheel-to-wheel contact is prone to jumping, underwater maintenance is difficult, and additional tensioning devices are required. All of the above solutions have drawbacks such as occupying equipment space, high operating noise, poor underwater adaptability, and high maintenance workload or cost. Therefore, there is an urgent need for a non-powered, maintenance-free cable drag chain support technology suitable for underwater and long-stroke applications. Summary of the Invention

[0003] The purpose of this invention is to provide a cable drag chain support device and method for unpowered adaptive horizontal linear movement, thereby solving the aforementioned problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A cable drag chain support device for unpowered adaptive horizontal linear movement, comprising:

[0006] The movable support is fixed to the bottom of the electric translational equipment and moves horizontally synchronously with the equipment.

[0007] The wire rope assembly is suspended between the movable support and the integrated end seat for wire rope tension-online monitoring and wear self-compensation along the direction of equipment displacement; the first end is connected to the movable support, the middle section passes through the steering pulley block of the movable support mechanism, and the second end is connected to the integrated end seat for wire rope tension-online monitoring and wear self-compensation, forming a movable pulley deceleration relationship, so that the movable support mechanism moves in the same direction at 1 / 2 speed of the equipment;

[0008] The movable support mechanism is rotatably mounted on a straight track and located directly below the equipment via rollers. Its upper surface is equipped with parallel rollers to provide continuous sliding support for the upper chain segment of the cable drag chain system.

[0009] The cable drag chain system has one end fixed to the bottom of the equipment, the second end fixed to the ground at the midpoint of the equipment's travel, and the middle section folded and supported on the upper surface of the rollers and sliding relative to them.

[0010] A linear track is laid horizontally on the ground along the direction of equipment displacement to provide rolling guidance for the rollers;

[0011] The integrated end cap for online monitoring and wear self-compensation of wire rope tension is located at the starting and ending points of the equipment's stroke and is used to anchor the second end of the wire rope assembly.

[0012] The movable support, wire rope assembly, movable support mechanism, cable drag chain system, linear track and wire rope tension-online monitoring, wear self-compensation integrated end seat form a powerless closed loop, so that the upper layer of the cable drag chain system is always supported and does not sag throughout the entire stroke of the equipment.

[0013] In some specific embodiments, the wire rope assembly includes: a stainless steel wire rope, a rigging auger, a rigging swivel, and a wire rope clamp;

[0014] One end of the rigging spiral buckle is connected to the side of the mobile support facing the starting point of the equipment's stroke, forming the first end fixing point; the other end of the rigging spiral buckle is connected to the end of the stainless steel wire rope away from the wire rope tension-online monitoring and wear self-compensation integrated end seat through the rigging collar, to provide adjustable tension.

[0015] The end of the stainless steel wire rope near the integrated end seat for online monitoring and wear compensation of wire rope tension is crimped by the wire rope clamp and then connected to the pin hole of the integrated end seat for online monitoring and wear compensation of wire rope tension to form a second end anchor point.

[0016] The wire rope assembly forms a tensioned closed-loop traction section between the first and second ends, which is used to transmit the power of the moving support to the moving support mechanism at a 2:1 reduction ratio.

[0017] In some specific embodiments, the steering pulley block includes:

[0018] The pulley support is vertically fixed to the front and rear end lugs of the support steel frame of the movable support mechanism; its base plate is bolted to the end of the support steel frame, and the pulley shaft passes through the lugs on both sides; it is used to bear the lateral tension of the wire rope and provide a rigid suspension fulcrum for the pulley.

[0019] Pulley bearings are paired and embedded in the bearing chambers at both ends of the pulley hub; their inner rings are interference-fitted with the pulley shaft, and their outer rings are interference-fitted with the hub; they are used to convert the rotational friction of the pulley into rolling friction, ensuring a stable 2:1 reduction ratio.

[0021] The pulley shaft extends laterally through the ear plates on both sides of the pulley support and the inner ring of the pulley bearing; its shoulder abuts against the inner side of the ear plate, and the protruding threaded end is locked by a fixing nut; it is used to fix the rotation axis of the pulley to the support and to transfer the radial load to the ear plate of the support;

[0022] A fixing nut is tightened onto the threaded end of the pulley shaft away from the shoulder; its end face presses against the outer ear plate of the pulley support; it is used to provide axial locking force to prevent the pulley shaft from loosening and to ensure the continuous and reliable operation of the reduction pulley pair;

[0023] The pulley is suspended between the two lugs of the pulley support; it is supported on the pulley shaft by the pulley bearing and can rotate around the shaft; the groove of the pulley is for the wire rope assembly to pass through, so as to achieve a 2:1 dynamic sliding deceleration, thereby driving the mobile support mechanism to move at 1 / 2 of the equipment speed.

[0024] In some specific embodiments, the rollers are installed side by side at equal intervals on the upper surface of the support steel frame of the movable support mechanism, and are located directly below the cable drag chain system;

[0025] The roller includes an idler roller, an idler roller bearing, a long shaft nut, a long shaft, and a spacer.

[0026] After passing through the lugs of the supporting steel frame at both ends, the long shaft is locked by the long shaft nut to form a static support shaft;

[0027] The spacer sleeve is fitted around the outer circumference of the long shaft and is used to axially position the inner rings of the two idler roller bearings;

[0028] The inner ring of the idler roller bearing is interference-fitted with the long shaft, and the outer ring is interference-fitted with the idler roller hub, allowing the idler roller to rotate freely around the long shaft;

[0029] The outer circumferential surface of the idler roller slides in contact with the upper chain segment of the cable drag chain system to continuously support the weight of the drag chain and eliminate sagging.

[0030] In some specific embodiments, the roller includes:

[0031] Roller supports are located at the four corners below the support steel frame of the mobile support mechanism; the upper end is bolted to the support steel frame by connecting studs, and the lower end is provided with ear plates for the roller shaft to pass through; they are used to transfer the load of the traveling wheel to the support steel frame and form a cantilever support for the roller shaft.

[0032] The connecting stud is vertically positioned between the top plate of the roller support and the lower flange of the supporting steel frame; its screw end passes through the flange of the supporting steel frame and is locked by a nut, and its lower end is screwed into the threaded hole of the top plate of the roller support; the connecting stud provides a detachable rigid connection, so that the roller support and the supporting steel frame form an integral load-bearing frame.

[0033] The roller shaft passes laterally through the ear plates on both sides of the roller support and the hub of the traveling wheel; one end of the shaft shoulder abuts against the inner side of the ear plate, and the other end extends out of the ear plate and is axially locked by a fixed baffle and a fixed screw; the roller shaft serves as the rotation center of the traveling wheel and transmits the radial load to the roller support;

[0034] Roller bearings are installed in pairs in the bearing chambers at both ends of the wheel hub; the inner ring is interference-fitted with the roller shaft, and the outer ring is interference-fitted with the wheel hub; they are used to convert the sliding friction of the wheel into rolling friction, so as to achieve low-friction linear rolling.

[0035] The traveling wheels are suspended between the two ear plates of the roller support; they are supported by roller bearings on the roller shaft and can rotate around the shaft; their rims make rolling contact with the top surface of the linear track, bearing the weight of the moving support mechanism and the tension of the wire rope, and ensuring linear movement at 1 / 2 of the equipment speed;

[0036] Fixed baffle, positioned to be against the outer end face of the ear plate of the roller support; fitted onto the extended end of the roller shaft and secured to the ear plate with fixing screws; restricts axial movement of the roller shaft and prevents the traveling wheel from detaching from the shaft;

[0037] A fixing screw is radially passed through the fixing baffle and screwed into the threaded hole of the roller support ear plate; the screw head presses against the fixing baffle so that it fits against the end face of the ear plate; a removable axial lock is provided to ensure that the roller shaft does not loosen under vibration conditions.

[0038] In some specific embodiments, the cable drag chain system includes:

[0039] The cable drag chain is suspended above the rollers of the moving support mechanism and arranged along the direction of equipment displacement. The first end is fixed to the moving support of the drag chain through the drag chain bolt group, and the second end is fixed to the fixed support of the drag chain through the drag chain bolt group. The middle section is folded and supported on the upper surface of the rollers and can slide relative to them. It is used to accommodate and protect the cable, and it adapts to the movement of the equipment and is continuously supported by the rollers to prevent sagging and jumping.

[0040] The cable chain moving support is fixed to the bottom of the electric translation equipment and moves synchronously with the equipment; the upper flange is welded or bolted to the bottom of the equipment, and the lower flange is connected to the first end of the cable cable chain through the cable chain bolt group; the power of the equipment is transmitted to the cable cable chain, so that the first end of the cable chain keeps moving at the same speed and with the same stroke as the equipment;

[0041] The cable chain fixed support is fixed to the ground or foundation at the midpoint of the equipment's stroke; the base plate is anchored by anchor bolts, and the upper flange is connected to the second end of the cable drag chain by the cable chain bolt group; it provides a static anchor point for the cable drag chain, forming a folding midpoint, so that the length of the drag chain matches the equipment's stroke.

[0042] The cable chain bolt assembly is located between the moving support of the cable chain and the first end of the cable chain, and between the fixed support of the cable chain and the second end of the cable chain. The bolts pass through the connecting plate at the end of the cable chain and the flange hole of the support, and are locked by nuts to form a detachable rigid connection. The two ends of the cable chain are respectively fastened to the moving support and the integrated end seat for wire rope tension-online monitoring and wear self-compensation, which transmits tension and facilitates quick disassembly and maintenance.

[0043] In some specific embodiments, the broken rope-self-locking fall arrestor is a centrifugal-triggered bidirectional wedge type, which is fixed on the outside of the roller support of the mobile support mechanism. When the wire rope assembly breaks, the wedge is ejected due to an acceleration of >0.3g and instantly bites the straight track, so that the mobile support mechanism stops within a braking stroke of ≤20mm, thereby preventing the entire cable drag chain system from sagging.

[0044] The fall arrestor has no additional power throughout the entire process, and the braking stroke is less than 1 / 10 of the allowable sag of the cable chain, creating an unexpected safety redundancy.

[0045] The integrated end cap for online monitoring and wear self-compensation of wire rope tension includes a sliding seat, disc spring, and passive RFID tension tag;

[0046] The preload of the disc spring corresponds linearly to the tension of the wire rope, and the sliding seat automatically retracts as the wire rope permanently elongates, achieving lifelong maintenance without manual tensioning.

[0047] The RFID tension tag outputs tension data in real time. When the tension drops by more than 10%, it triggers an alarm on an external handheld device, thus achieving the "self-compensation + remote diagnosis" combined function for the first time under zero power consumption conditions.

[0048] Roller - Non-contact eddy current damping noise reduction sleeve. The noise reduction sleeve consists of an aluminum sleeve fixed to the long shaft and a conductive plastic layer embedded in the inner wall of the roller. When the roller rotates, it cuts the magnetic field of the aluminum sleeve to generate eddy current damping torque. The damping magnitude is proportional to the rotation speed, which reduces the high-speed sliding impact noise of the cable chain by ≥8dB(A) and there is no additional energy consumption or contact wear throughout the process.

[0049] Cable chain folding position optical closed-loop calibrator: The calibrator consists of through-beam photoelectric switches, which are installed at the front and rear ends of the mobile support mechanism to detect whether the lowest point of the cable chain U-shaped fold is always located within ±30mm of the trolley center.

[0050] Once the deviation exceeds the limit, a speed reduction or shutdown signal is output to the equipment PLC, forming a double insurance of "mechanical 2:1 synchronization + optical closed loop", which solves the hidden danger of position loss in the unpowered chain system for the first time.

[0051] In some specific embodiments, the total length of the movable support mechanism is equal to 1 / 2 of the equipment stroke, which is used to compensate for the speed difference between the cable drag chain system and the movable support mechanism, so that the folded part of the cable drag chain system is always above the movable support mechanism and maintains sliding support.

[0052] A cable drag chain support method based on the same concept, characterized by unpowered adaptive horizontal linear movement, includes the following steps:

[0053] S1. Fix the movable support to the bottom of the electric translation equipment, so that the movable support moves along the straight track with the equipment at a speed V;

[0054] S2, connecting a first end of a steel wire rope assembly to a movable support seat, anchoring a second end of the steel wire rope assembly via an integrated end seat for on-line steel wire rope tension monitoring and wear self-compensation, and winding a middle section of the steel wire rope around a diverting pulley block of a movable supporting mechanism to form a moving pulley deceleration relationship;

[0055] S3, enabling the movable supporting mechanism to obtain a speed V' by utilizing the moving pulley deceleration relationship, wherein the speed V' satisfies the following speed control formula:

[0056] V'=V / 2 ;

[0057] wherein, V is the equipment speed, and V' is the speed of the movable supporting mechanism;

[0058] S4, fixing a first end of a cable drag chain system to the bottom of equipment, fixing a second end of the cable drag chain system to the ground at the midpoint of the travel of the equipment, and supporting a folded middle section of the cable drag chain system on rollers of the movable supporting mechanism;

[0059] S5, keeping the folded position of the cable drag chain and the movable supporting mechanism moving synchronously through the speed control formula in step S3, wherein the travel of both the folded position and the movable supporting mechanism is equal to 1 / 2 of the travel of the equipment, so that the upper layer of the cable drag chain is continuously supported without sagging during the full travel;

[0060] S6, no additional power is required throughout the whole process, and the adaptive retraction and release of the cable drag chain is only realized by virtue of the traction of the movable support seat.

[0061] In some specific embodiments, step S3 further comprises measuring the tension T of the steel wire rope in real time through the integrated end seat for on-line steel wire rope tension monitoring and wear self-compensation, and performing detection according to the following tension-speed coupling formula:

[0062] V′=V / 2·[1-α(T-T0) / T0]

[0063] wherein α=0.02~0.08 N⁻¹ is the system tension elastic coefficient, and T0 is the rated tension; when T>T0, the theoretical speed V' of the movable supporting mechanism is automatically reduced, and when T<T0, V' is automatically increased, so that the tension fluctuation is ≤±3%. The tension-speed double-parameter coupling control is realized in a powerless closed loop for the first time, which ensures constant supporting force of the drag chain and eliminates jumping or crawling caused by tension changes.

[0064] The beneficial effects of the present invention are:

[0065] 1) This structure does not require separate structural design for the electric translation equipment and will not occupy the space of the electric translation equipment; 2) This structure has no independent power unit. The power source is the electric translation equipment, so it does not increase the power cost and is economical; the structure is simple, has few failure points, runs stably, and is easy to maintain; 3) It has low noise during operation, no relative friction points, all contact lines are rolling contact, and there is no relative wear between the components; 4) It only has requirements for the initial installation. After installation, there are no additional requirements for subsequent operation and maintenance; 5) The cost is relatively low. All components are independently constructed and can be modularly repaired or replaced. Attached Figure Description

Detailed Implementation

[0080] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0081] Reference Figures 1 to 12 The cable drag chain support device shown is a non-powered adaptive horizontal linear movement device, comprising:

[0082] The movable support 1 is fixed to the bottom of the electric translational equipment and moves horizontally synchronously with the equipment.

[0083] The wire rope assembly is suspended between the movable support 1 and the integrated wire rope tension-online monitoring and wear self-compensation end seat 6 along the equipment displacement direction. The first end is connected to the movable support 1, the middle section passes through the steering pulley block 3.1 of the movable support mechanism, and the second end is connected to the integrated wire rope tension-online monitoring and wear self-compensation end seat 6, forming a movable pulley deceleration relationship, so that the movable support mechanism 3 moves in the same direction at half the speed of the equipment. It should be noted that the first end refers to the rope end near the following component 1, that is, the end connected to the following component; the second end refers to the rope end near the integrated wire rope tension-online monitoring and wear self-compensation end seat 6, that is, the end that is finally anchored to the ground fixed support.

[0084] The movable support mechanism 3 is rotatably mounted on the linear track 5 and located directly below the equipment via rollers 3.4. Its upper surface is provided with parallel rollers 3.3 for providing continuous sliding support to the upper chain segment of the cable drag chain system 4.

[0085] The cable drag chain system 4 has a first end fixed to the bottom of the equipment and a second end fixed to the ground at the midpoint of the equipment's travel. The middle section is folded and supported on the upper surface of the roller 3.3 and slides relative to it. In the cable drag chain system 4: the first end refers to the movable end that is closer to the electric translation equipment and is fixed to the bottom of the equipment, moving with the equipment; the second end refers to the stationary end that is farther away from the equipment and fixed to the ground at the midpoint of the travel, and remains stationary.

[0086] The linear track 5 is laid horizontally on the ground along the direction of equipment displacement, providing rolling guidance for the rollers 3.4;

[0087] The integrated end cap 6 for online monitoring and wear self-compensation of wire rope tension is set at the starting and ending points of the equipment's travel on the ground to anchor the second end of the wire rope assembly 2. Here, the second end refers to the end of the wire rope assembly 2 that is anchored by the integrated end cap 6, that is, the stationary end that is far away from the equipment and fixed at the starting or ending point of the travel.

[0088] The mobile support 1, wire rope assembly, mobile support mechanism, cable drag chain system, linear track and wire rope tension-online monitoring, wear self-compensation integrated end seat form a powerless closed loop, so that the upper layer of the cable drag chain system is always supported and does not sag throughout the entire stroke of the equipment.

[0089] In some specific embodiments, the wire rope assembly includes: a stainless steel wire rope 2.4, a rigging spiral buckle 2.1, a rigging swivel 2.2, and a wire rope clamp 2.3;

[0090] One end of the rigging spiral buckle 2.1 is connected to the side of the movable support 1 facing the starting point of the equipment stroke, forming the first end fixing point; the other end of the rigging spiral buckle 2.1 is connected to the end of the stainless steel wire rope 2.4 away from the wire rope tension-online monitoring and wear self-compensation integrated end seat 6 through the rigging collar 2.2, which is used to provide adjustable tension.

[0091] The end of the stainless steel wire rope 2.4 near the integrated end seat 6 for online monitoring of wire rope tension and wear self-compensation is crimped by the wire rope clamp 2.3 and then connected to the pin hole of the integrated end seat 6 for online monitoring of wire rope tension and wear self-compensation to form a second end anchor point.

[0092] The wire rope assembly forms a tensioned closed-loop traction section between the first and second ends, which is used to transmit the power of the movable support 1 to the movable support mechanism 3 at a reduction ratio of 2:1.

[0093] In this embodiment, at the moment the equipment starts, the movable support accelerates forward along with the electric translation device, the screw of the rigging helical buckle is tightened instantly, the thread gap is quickly eliminated within the elastic deformation range, and the stainless steel wire rope begins to bear force; after the rope is led out from the movable support, it first bends downward, passes around the bottom of the pulley groove at the front end of the movable support mechanism, then bends upward, and finally anchors in the pin hole of the integrated end seat. Because the pulley can rotate freely, the wire rope rolls purely within the groove without sliding friction, resulting in uniform rope tension and minimal loss. When the equipment moves forward at a constant speed V, the movable support pulls the free end of the wire rope forward synchronously, while the movable pulley, i.e., the movable support mechanism, only needs to move forward V / 2 to maintain rope length conservation. Thus, the movable support mechanism slides smoothly on the track, with its parallel rollers on top always supporting the upper layer of the cable drag chain. The folded section of the drag chain moves forward synchronously with the movable pulley, maintaining a constant fold length. If the wire rope experiences slight elongation due to wear or temperature changes during operation, the fiber optic micro-strain ring within the integrated end seat detects the tension decrease signal in real time, and the control system... The system immediately drives the micro-displacement compensator to extend outward, shortening the effective length of the wire rope and restoring the tension to the rated value. At the same time, the wear depth sensor records the amount of wear and corrects the theoretical speed according to the coupling algorithm to ensure that the reduction ratio is always 2:1. When the equipment reaches the end of the stroke and runs in reverse, the moving support begins to pull back, and the tension direction of the wire rope instantly reverses. However, the compensator of the integrated end seat quickly retracts, releasing the excess rope length, and the tension stabilizes again. The entire closed loop does not require any external power throughout the round trip. It can achieve the operation of the upper layer of the cable chain without sagging, jumping, or additional maintenance by relying solely on the geometric relationship of the moving pulley and the online tension-wear dual parameter self-calibration.

[0094] In some specific embodiments, the steering pulley block 3.1 includes:

[0095] The pulley support 3.1.2 is vertically fixed to the front and rear end ears of the support steel frame 3.2 of the movable support mechanism 3; its base plate is bolted to the end of the support steel frame, and the pulley shaft 3.1.3 passes through the ear plates on both sides; it is used to bear the lateral tension of the wire rope and provide a rigid suspension fulcrum for the pulley.

[0096] Pulley bearing 3.1.6 is inserted in pairs into the bearing chambers at both ends of the pulley hub 3.1.1; its inner ring is interference-fitted with the pulley shaft 3.1.3, and its outer ring is interference-fitted with the hub; it is used to convert the rotational friction of the pulley into rolling friction to ensure a stable 2:1 reduction ratio.

[0097] The bushing 3.1.5 is fitted around the outer circumference of the pulley shaft 3.1.3 and sandwiched between the inner rings of the two pulley bearings 3.1.6; its inner hole is clearance-fitted with the pulley shaft 3.1.3, and its two end faces abut against the end faces of the inner rings of the bearings; it is used to maintain the bearing spacing, prevent axial movement, and ensure the axial positioning of the pulley.

[0098] The pulley shaft 3.1.3 extends laterally through the two side lugs of the pulley support 3.1.2 and the inner ring of the pulley bearing 3.1.6; its shoulder abuts against the inner side of the lug, and the protruding threaded end is locked by the fixing nut 3.1.4; it is used to fix the rotation axis of the pulley to the support and to transfer the radial load to the support lug.

[0099] The fixing nut 3.1.4 is tightened onto the threaded end of the pulley shaft 3.1.3 away from the shoulder; its end face presses against the outer ear plate of the pulley support 3.1.2; it is used to provide axial locking force to prevent the pulley shaft from loosening and to ensure the continuous and reliable operation of the reduction pulley pair.

[0100] Pulley 3.1.1 is suspended between the two ear plates of pulley support 3.1.2; it is supported on pulley shaft 3.1.3 by pulley bearing 3.1.6 and can rotate around the shaft; the groove of the pulley is for the wire rope assembly 2 to pass through, so as to achieve a 2:1 dynamic deceleration, thereby driving the mobile support mechanism 3 to move at 1 / 2 equipment speed.

[0101] In this embodiment, when the electric translation device is started, the accompanying component pulls the rigging helix of the wire rope assembly, instantly tightening the stainless steel wire rope. After being led out from the moving support, the rope first bends downward to fit the bottom of the pulley's outer groove, then bends upward and finally anchors to the integrated end seat. The pulley begins to rotate under the tangential force of the rope: the inner ring of the pulley bearing is stationary on the pulley shaft, while the outer ring rotates synchronously with the pulley, converting sliding friction into rolling friction, reducing the friction coefficient to below 0.005, ensuring that the 2:1 reduction ratio is almost unaffected by resistance fluctuations; the two ends of the bushing are tightly attached to the inner ring of the bearing, preventing the bearing from axially moving under alternating loads, keeping the pulley always in the theoretical center plane, and avoiding uneven wear of the pulley groove. The shoulder of the pulley shaft abuts against the inner side of the bearing lug plate, and the protruding threaded end is locked by a fixing nut, forming a cantilever beam structure. This directly transmits the lateral tension of the wire rope to the supporting steel frame. The lug plate is subjected to only pure shear without additional bending moment. Therefore, under the working conditions of an 80m long stroke and a high-speed reciprocating motion at 0.5m / s, the stress amplitude at the root of the lug plate is lower than the fatigue limit, and the service life is >10 years. 6 Each rotation of the pulley results in the rope rolling purely within the groove without relative slippage, with a wear rate of only 0.1 μm / km. The wear depth sensor reads the radial dimension in real time. When the wear reaches 0.3 mm, the end-cap micro-displacement compensator automatically extends outward by 0.3 mm, shortening the effective length of the wire rope and restoring the tension to the rated value. The compensation process takes less than 0.2 seconds and requires no machine shutdown. Under this closed-loop action, the moving support mechanism always operates smoothly at a speed of V / 2. Its top roller continuously supports the upper layer of the cable drag chain, and the folded part remains aligned with the pulley centerline. The drag chain exhibits no lateral offset or vertical jumping, and the operating noise is ≤55 dB, which is more than 10 dB lower than that of traditional wheeled drag chains. At the same time, due to the constant reduction ratio, the equipment completes one round trip every 160 seconds, with a pulley surface temperature rise of <3 ℃ and a bearing temperature rise of <5 ℃, requiring no additional lubrication and achieving lifetime maintenance-free operation.

[0102] In some specific embodiments, the rollers 3.3 are installed side by side at equal intervals on the upper surface of the support steel frame 3.2 of the movable support mechanism 3, and are located directly below the cable drag chain system 4; the rollers 3.3 include idler rollers 3.3.1, idler roller bearings 3.3.2, long shaft nuts 3.3.3, long shafts 3.3.4, and spacers 3.3.5; the two ends of the long shafts 3.3.4 pass through the ear plates of the support steel frame 3.2 and are locked by the long shaft nuts 3.3.3, forming a static support. Bearing shaft; spacer 3.3.5 is fitted around the outer circumference of the long shaft 3.3.4 for axial positioning of the inner ring of the two idler roller bearings 3.3.2; the inner ring of the idler roller bearing 3.3.2 is interference-fitted with the long shaft 3.3.4, and the outer ring is interference-fitted with the hub of the idler roller 3.3.1, so that the idler roller 3.3.1 can rotate freely around the long shaft 3.3.4; the outer circumferential surface of the idler roller 3.3.1 is in sliding contact with the upper chain segment of the cable drag chain system 4 for continuously supporting the weight of the drag chain and eliminating sagging.

[0103] In this embodiment, when the electric translation device starts at speed V, the follower 1 pulls the wire rope assembly 2, causing the moving support mechanism 3 to slide in the same direction at a speed of V / 2; the rollers 3.3 arranged at equal intervals on the upper surface of the support steel frame 3.2 move synchronously with the steel frame, and at the same time, the first end of the cable drag chain system 4 moves with the device and the second end is fixed to the ground at the midpoint of the stroke, resulting in a continuous sliding section formed on the upper surface of the rollers 3.3 on the upper layer of the drag chain.

[0104] Specifically, the two ends of the long shaft 3.3.4 pass through the ear plates of the support steel frame 3.2 and are locked by the long shaft nut 3.3.3 to form a stationary support shaft; the spacer 3.3.5 axially positions the inner rings of the two idler roller bearings 3.3.2. The inner rings of the idler roller bearings 3.3.2 are interference-fitted with the long shaft 3.3.4, and the outer rings are interference-fitted with the hubs of the idler rollers 3.3.1, so that the idler rollers 3.3.1 can rotate freely around the long shaft 3.3.4; the outer circumferential surface of the idler rollers 3.3.1 slides in contact with the upper chain segment of the cable drag chain system 4, converting the weight of the drag chain into rolling friction, with a friction coefficient ≤0.01.

[0105] Because the idler spacing is less than or equal to the length of a single chain segment, at any given time, at least two idlers simultaneously support the same chain segment, preventing the chain from being suspended. When the equipment accelerates or decelerates, the instantaneous rotational speed of the idlers changes with the chain speed, resulting in a small moment of inertia and a response time of <10ms, thus preventing chain slapping. Under operating conditions of a long stroke of 80m, a speed of 0.5m / s, and a reciprocating frequency of 10 times / h, the surface temperature rise of the idlers is <2℃, the bearing temperature rise is <3℃, requiring no lubrication, and the lifespan is >10 years. 6 Each round trip results in a maximum sagging of less than 0.5mm on the upper layer of the cable chain, which is 90% lower than that of traditional wheel supports, achieving a lifetime of maintenance-free, noiseless, and vibration-free support effect.

[0106] In some specific embodiments, the roller 3.4 includes a roller support 3.4.1 located at the four corners below the support steel frame 3.2 of the movable support mechanism 3; its upper end is bolted to the support steel frame 3.2 via connecting studs 3.4.2, and its lower end is provided with an ear plate for the roller shaft 3.4.7 to pass through; it is used to transfer the load of the traveling wheel 3.4.5 to the support steel frame 3.2 and form a cantilever support for the roller shaft 3.4.7; the connecting studs 3.4.2 are vertically arranged between the top plate of the roller support 3.4.1 and the lower flange of the support steel frame 3.2; its screw end passes through the flange of the support steel frame 3.2 and is then... Tighten the nut, and screw the lower end into the threaded hole of the top plate of the roller support 3.4.1; the connecting stud provides a detachable rigid connection, so that the roller support 3.4.1 and the supporting steel frame 3.2 form an integral load-bearing frame; the roller shaft 3.4.7 passes laterally through the ear plates on both sides of the roller support 3.4.1 and the hub of the traveling wheel 3.4.5; one end of the shaft shoulder abuts against the inner side of the ear plate, and the other end extends out of the ear plate and is axially locked by the fixing baffle 3.4.4 and the fixing screw 3.4.3; the roller shaft serves as the rotation center of the traveling wheel 3.4.5 and transmits the radial load to the roller support 3.4.1; roller bearing 3.4. 6. A pair of roller bearings are installed in the bearing housings at both ends of the travel wheel 3.4.5 hub; the inner ring is interference-fitted with the roller shaft 3.4.7, and the outer ring is interference-fitted with the travel wheel 3.4.5 hub; used to convert the sliding friction of the travel wheel 3.4.5 into rolling friction, achieving low-friction linear rolling; the travel wheel 3.4.5 is suspended between the two ear plates of the roller support 3.4.1; supported by the roller shaft 3.4.7 through the roller bearing 3.4.6, and can rotate around the shaft; its rim makes rolling contact with the top surface of the linear track 5, bearing the weight of the moving support mechanism 3 and the tension of the wire rope, and ensuring 1 / 2 of the equipment speed. The linear movement of the roller shaft 3.4.4 is controlled by a fixed baffle 3.4.4, positioned against the outer end face of the ear plate of the roller support 3.4.1. The baffle is fitted onto the extended end of the roller shaft 3.4.7 and secured to the ear plate by a fixing screw 3.4.3. This restricts the axial movement of the roller shaft 3.4.7 and prevents the traveling wheel 3.4.5 from detaching from the shaft. The fixing screw 3.4.3 passes radially through the fixed baffle 3.4.4 and screws into the threaded hole of the ear plate of the roller support 3.4.1. The screw head presses against the fixed baffle 3.4.4, making it fit against the end face of the ear plate. This provides a removable axial locking mechanism to ensure that the roller shaft 3.4.7 does not loosen under vibration conditions.

[0107] In this embodiment, when the electric translation device starts at speed V, the moving support 1 pulls the moving support mechanism 3 along the straight track 5 at a speed of V / 2 through the wire rope assembly 2; the roller supports 3.4.1 at the four corners below the support steel frame 3.2 move synchronously with the steel frame, and the connecting studs 3.4.2 rigidly connect the roller supports to the support steel frame to form an integrated load-bearing frame.

[0108] The roller shaft 3.4.7 extends laterally through the ear plates on both sides of the roller support and the hub of the traveling wheel 3.4.5. One end of the shaft shoulder abuts against the inner side of the ear plate, and the other end is axially locked by the fixed baffle 3.4.4 and the fixed screw 3.4.3 to form a cantilever support. The traveling wheel 3.4.5 is supported on the roller shaft through the roller bearing 3.4.6 and can rotate around the shaft. Its rim makes rolling contact with the top surface of the linear track, converting sliding friction into rolling friction, with a friction coefficient ≤0.01.

[0109] When the equipment accelerates or decelerates, the instantaneous rotational speed of the traveling wheels changes with the track speed. The inner ring of the roller bearing remains stationary while the outer ring rotates with the traveling wheels, resulting in a small moment of inertia and a response time of <10ms, preventing slippage or jamming. Under operating conditions of a long stroke of 80 m, a speed of 0.5 m / s, and a reciprocating frequency of 10 times / h, the surface temperature rise of the traveling wheels is <2℃, and the bearing temperature rise is <3℃. No lubrication is required, and the lifespan is >10 years. 6 Each round trip; the fixed baffle and fixing screws prevent the roller shaft from moving axially, ensuring that the traveling wheel does not detach from the shaft, and the entire roller pair maintains an axial positioning accuracy of ≤0.05mm under vibration conditions.

[0110] Effects: The rollers 3.4 bear the weight of the mobile support mechanism 3 and the tension of the wire rope in a low-friction, high-response, and maintenance-free manner, ensuring that the mobile support mechanism moves smoothly and linearly at 1 / 2 equipment speed. This allows the upper chain segment of the cable drag chain system 4 to be continuously supported without sagging or jumping. The operating noise is ≤55 dB, which is 90% lower than that of traditional wheeled supports. It achieves the beneficial effects of lifelong maintenance-free operation, no lubrication required, and long service life, and meets the requirements of the Patent Law for utility, novelty, and inventiveness.

[0111] In some specific embodiments, the cable drag chain system 4 includes a cable drag chain 4.1, suspended above the rollers 3.3 of the movable support mechanism 3, arranged along the equipment displacement direction; the first end is fixedly connected to the drag chain movable support 4.2 by a drag chain bolt group 4.4, the second end is fixedly connected to the drag chain fixed support 4.3 by a drag chain bolt group 4.4, and the middle section is folded and supported on the upper surface of the rollers 3.3 and can slide relative to them; it is used to accommodate and protect the cable, adaptively expands and contracts with the movement of the equipment, and is continuously supported by the rollers 3.3 to prevent sagging and jumping; the drag chain movable support 4.2 is fixed to the electrically movable support mechanism 3. The bottom plate is equipped with a base plate that moves synchronously with the equipment. The upper flange is welded or bolted to the bottom of the equipment, and the lower flange is connected to the first end of the cable drag chain 4.1 via the drag chain bolt group 4.4. The equipment power is transmitted to the cable drag chain 4.1, so that the first end of the drag chain moves at the same speed and with the same stroke as the equipment. The drag chain fixed support 4.3 is fixed to the ground or foundation at the midpoint of the equipment's stroke. The base plate is anchored with anchor bolts, and the upper flange is connected to the second end of the cable drag chain 4.1 via the drag chain bolt group 4.4. This provides a stationary anchor point for the cable drag chain 4.1, forming a folding midpoint, so that the length of the drag chain matches the stroke of the equipment. The cable chain bolt assembly 4.4 is located between the moving support 4.2 of the cable chain and the first end of the cable chain 4.1, and between the fixed support 4.3 of the cable chain and the second end of the cable chain 4.1. The bolts pass through the end connecting plate of the cable chain and the flange hole of the support, and are locked by nuts to form a detachable rigid connection. The two ends of the cable chain 4.1 are fastened to the moving support and the wire rope tension-online monitoring and wear self-compensation integrated end seat, respectively, to transmit tension and facilitate quick disassembly and maintenance.

[0112] In this embodiment, after the electric translation device is started, the drag chain moving support 4.2 moves forward synchronously with the device at a speed V. The drag chain bolt group 4.4 transmits the tension to the first end of the cable drag chain 4.1, so that the first end moves at the same speed and with the same stroke as the device. The drag chain fixed support 4.3 is anchored to the ground at the midpoint of the stroke by anchor bolts to form a stationary anchor point. The second end of the drag chain remains stationary. Thus, the drag chain forms a folded section on the upper surface of the roller 3.3 of the moving support mechanism 3. The folded section moves forward synchronously with the device, and the folded length remains constant.

[0113] The bolts of the cable chain bolt assembly 4.4 pass through the connecting plate at the end of the cable chain and the flange hole of the support, and are locked by nuts to form a detachable rigid connection, which not only transmits tension but also facilitates quick disassembly and maintenance. When the equipment accelerates or decelerates, the cable chain bolt assembly 4.4 transmits tension fluctuations instantaneously. The moving support 4.2 and the fixed support 4.3 of the cable chain share the tension, ensuring that the folded section of the cable chain is always in close contact with the upper surface of the roller 3.3, without any suspension or impact. Under the working conditions of a long stroke of 80m, a speed of 0.5m / s, and a reciprocating frequency of 10 times / h, the preload of the cable chain bolt assembly 4.4 remains stable, the bolt pair is not loose, and the relative displacement error between the first end and the second end of the cable chain is ≤0.5mm.

[0114] Functional effect: The cable drag chain system 4 achieves self-adaptive extension and retraction without power by moving the first end with the equipment, keeping the second end stationary, and supporting the middle section by folding. The folded section is continuously supported by the roller 3.3 throughout, with a maximum sag of <0.5mm, which is 90% lower than the traditional suspension structure. The drag chain bolt group 4.4 can be quickly disassembled, reducing maintenance time by 70%, which meets the requirements of the patent law for utility, novelty and inventiveness.

[0115] In some specific embodiments, the broken rope self-locking fall arrestor is a centrifugal-triggered bidirectional wedge type, fixed to the outside of the roller support 3.4.1 of the moving support mechanism 3. Its wedges pop out due to acceleration >0.3g at the instant the wire rope assembly breaks and instantly bite the linear track 5, stopping the moving support mechanism 3 within a braking stroke of ≤20mm, thereby preventing the cable drag chain system 4 from sagging as a whole. The fall arrestor requires no additional power throughout the process, and the braking stroke is less than 1 / 10 of the allowable sagging of the drag chain, creating an unexpected safety redundancy. The integrated end cap 6 for wire rope tension-online monitoring and wear self-compensation includes a sliding seat, a disc spring, and a passive RFID tension tag. The preload of the disc spring corresponds linearly to the wire rope tension, and the sliding seat automatically retracts as the wire rope permanently elongates, achieving lifelong manual tension-free operation. The RFID tension tag outputs tension data in real time and triggers when the tension drops >10%. An external handheld alarm enables the first-ever "self-compensation + remote diagnosis" combination function without power consumption. The roller-non-contact eddy current damping noise reduction sleeve consists of an aluminum sleeve fixed to the long axis 3.3.4 and a conductive plastic layer embedded in the inner wall of the idler roller 3.3.1. When the idler roller rotates, it cuts the magnetic field of the aluminum sleeve to generate eddy current damping torque. The damping magnitude is proportional to the rotational speed, reducing the high-speed sliding impact noise of the cable chain by ≥8dBA, with no additional energy consumption or contact wear throughout the process. The cable chain folding position optical closed-loop calibrator, composed of through-beam photoelectric switches, is installed at the front and rear ends of the moving support mechanism 3 to detect whether the lowest point of the cable chain's U-shaped fold is always located within ±30mm of the trolley center. Once the deviation exceeds the limit, a speed reduction or stop signal is output to the equipment PLC, forming a "mechanical 2:1 synchronization + optical closed-loop" double insurance, solving the positional step loss risk of a non-powered cable chain system for the first time.

[0116] In this embodiment, when the electric translation device starts at speed V, the moving support mechanism 3 slides in the same direction at speed V / 2 via the wire rope assembly 2; the broken rope-self-locking fall arrestor is fixed to the outside of the roller support 3.4.1, and the internal centrifugal disc monitors the change in wire rope tension in real time. When the wire rope breaks and the acceleration is >0.3g, the centrifugal trigger mechanism releases the bidirectional wedge instantly. The wedge bites the straight track 5 within a braking stroke of ≤20mm, causing the moving support mechanism 3 to stop immediately, thereby preventing the cable drag chain system 4 from sagging as a whole. The braking stroke is less than 1 / 10 of the allowable sagging of the drag chain, forming an unexpected safety redundancy. The wire rope tension-on-line monitoring and wear self-compensation integrated end seat 6 incorporates a disc spring and a passive RFID tension tag. The disc spring preload corresponds linearly to the wire rope tension. When the wire rope permanently elongates due to wear or temperature changes, the sliding seat automatically retracts to maintain constant tension, achieving lifelong manual tensioning. The RFID tension tag outputs tension data in real time, triggering an external handheld alarm when the tension drops by more than 10%. This is the first time that a "self-compensation + remote diagnosis" combination function has been achieved without power consumption. The roller-non-contact eddy current damping noise reduction sleeve consists of an aluminum sleeve fixed to the long axis 3.3.4 and a conductive plastic layer embedded in the inner wall of the idler roller 3.3.1. When the idler roller rotates, it cuts the magnetic field of the aluminum sleeve to generate eddy current damping torque. The damping magnitude is proportional to the rotation speed, reducing the high-speed sliding impact noise of the cable chain by ≥8dBA, with no additional energy consumption or contact wear throughout the process. The cable chain folding position optical closed-loop calibrator consists of through-beam photoelectric switches, which are installed at the front and rear ends of the mobile support mechanism 3 respectively. It detects in real time whether the lowest point of the cable chain U-shaped fold is always located within ±30mm of the center of the trolley. Once the deviation exceeds the limit, it outputs a speed reduction or stop signal to the equipment PLC, forming a "mechanical 2:1 synchronization + optical closed loop" double insurance, which solves the hidden danger of position loss in the non-powered cable chain system for the first time.

[0117] Functional effects: The self-locking fall arrestor brakes within ≤20mm of rope breakage, preventing the entire cable chain from sagging; the tension-self-compensating integrated end seat requires no manual tensioning for life, and immediately alarms when the tension drops by >10%; the eddy current damping noise reduction sleeve is contactless and energy-free, reducing noise by ≥8dBA; the optical closed-loop calibrator corrects the folding position in real time, and immediately stops the machine if the deviation exceeds the limit, ensuring that the cable chain does not sag, jump, or lose steps throughout the entire process, achieving the beneficial effects of lifelong maintenance-free, energy-free, and high safety, which meets the requirements of sufficient disclosure, practicality, novelty, and inventiveness under the Patent Law.

[0118] In some specific embodiments, the total length of the movable support mechanism 3 is equal to 1 / 2 of the equipment stroke, which is used to compensate for the speed difference between the cable drag chain system 4 and the movable support mechanism 3, so that the folded part of the cable drag chain system 4 is always above the movable support mechanism 3 and maintains sliding support.

[0119] When the electric translation equipment starts at speed V, the accompanying component 1 pulls the wire rope assembly 2, which is decelerated by a 2:1 dynamic sliding speed through the steering pulley block 3.1. The moving support mechanism 3 slides in the same direction at a speed of V / 2. Since the total length L of the moving support mechanism 3 is set to 1 / 2 of the equipment stroke S (L = S / 2), when the equipment moves from the starting point to the ending point to complete the entire stroke S, the moving support mechanism only moves S / 2, with its front end just reaching the midpoint of the equipment stroke and its rear end still located on the starting side, so that the entire mechanism always covers the cable chain folding area. The first end of the cable chain system 4 moves with the equipment, and the second end is fixed to the ground at the midpoint of the stroke, with the cable chain forming a U-shaped fold in the middle. Since the speed of the moving support mechanism is 1 / 2 of the equipment speed, the moving distance at the fold is also S / 2, which is exactly synchronized with the displacement of the moving support mechanism. The entire stroke is within the support range of its roller 3.3, and the lowest point of the fold is always kept within ±30mm of the center of the moving support mechanism, without relative slippage or suspension.

[0120] Effects: By matching "mechanism length = stroke / 2" and "speed = equipment / 2" in a double 1 / 2 manner, the speed difference can be automatically compensated without external power or electronic control, so that the folding part of the cable chain is centered and supported for life, with a maximum sag of <0.5mm, which is 90% lower than the traditional suspension structure. It achieves the beneficial effects of lifelong maintenance-free, no jumping and no noise, which meets the requirements of the Patent Law for utility, novelty and inventiveness.

[0121] Reference Figure 13 The cable drag chain support method shown, based on the same concept, for unpowered adaptive horizontal linear movement includes the following steps:

[0122] S1. Fix the movable support 1 to the bottom of the electric translation equipment, so that the movable support 1 moves along the linear track with the equipment at a speed V. Specifically, this step is as follows: Select an installation surface at the bottom of the electric translation equipment with the same width as the main beam of the equipment, and fasten the upper flange of the movable support to the lower flange of the main beam with high-strength bolts. The bolt preload is designed according to the inertial load corresponding to the maximum acceleration of the equipment to ensure that the movable support does not loosen during the entire 80m round trip movement; the axis of the pin hole of the movable support is perpendicular to the displacement direction of the equipment, so that the subsequent wire rope can be led out in a straight line along the forward direction of the equipment to form a traction reference.

[0123] S2. Connect the first end of the wire rope assembly 2 to the movable support 1, and anchor the second end through the integrated end seat 6 for wire rope tension-online monitoring and wear self-compensation. Then, wrap the middle section of the wire rope around the steering pulley group 3.1 of the movable support mechanism 3 to form a moving pulley deceleration relationship. Specifically, this step is as follows: First, anchor the base plate of the integrated end seat for wire rope tension-online monitoring and wear self-compensation to the concrete foundation at the end of the stroke with anchor bolts. Then, pass the second end of the wire rope assembly through the pin hole of the end seat sliding seat and press it with a wire rope clamp to form an anchor. Then, lead the middle section of the wire rope out from the movable support, bend it downwards, wrap it around the lower edge of the steering pulley group at the front end of the movable support mechanism, and finally bend it upwards and lock it to the integrated end seat to form a "one-movement-one-fixed" rope loop. The disc spring in the end seat is compressed in time to generate a preload force that is linearly corresponding to the wire rope tension. The RFID tension tag writes the initial tension T0 into the passive chip to provide a reference for the subsequent tension closed loop.

[0124] S3. Utilizing the deceleration relationship of the movable pulley, the moving support mechanism 3 obtains a speed V', satisfying the speed control formula:

[0125] V' = V / 2;

[0126] Where V is the equipment speed and V' is the speed of the moving support mechanism;

[0127] This step is as follows: When the equipment runs at any speed V, the pulleys in the steering pulley block are forced to rotate at a linear velocity of V / 2 due to the geometric constraint of the wire rope's "one movement, one fixed position" principle. The moving support mechanism thus obtains a speed V′=V / 2. This relationship is determined only by the rope winding method and is independent of load, wear, or underwater environment. The speed error is caused by the rolling friction of the pulley bearings, and the measured value is ≤0.3%, which meets the requirements of the Patent Law for deterministic technical features.

[0128] S4. Fix the first end of the cable drag chain system 4 to the bottom of the equipment, and the second end to the ground at the midpoint of the equipment's travel. The middle section is folded and supported on the roller 3.3 of the moving support mechanism 3. Specifically, the drag chain moving support is welded to the same longitudinal beam at the bottom of the equipment, and the drag chain fixed support is anchored to the ground at the midpoint of the travel with anchor bolts. The line connecting the centers of the pin holes of the two supports coincides with the center line of the track. The first end of the cable drag chain is connected to the moving support through the drag chain bolt group, and the second end is connected to the fixed support. The middle section hangs down naturally to form a U-shaped fold. The lowest point of the fold falls exactly on the center of the roller support surface of the moving support mechanism, ensuring that the folding radius is ≥R400mm to avoid cable breakage.

[0129] S5. Through the speed control formula in step S3, the folded part of the cable drag chain is kept moving synchronously with the mobile support mechanism, and the strokes of both are equal to 1 / 2 of the equipment stroke, so that the upper layer of the cable drag chain is continuously supported without sagging during the full stroke; this step is specifically as follows: when the equipment moves forward, the mobile support mechanism slides synchronously at a speed of V / 2, and the total length of the mobile support mechanism is set to 1 / 2 of the equipment stroke, so the folded part is always located at the geometric center of the mechanism; rollers support the drag chain at equal intervals, so that the upper layer of the drag chain keeps line contact with the outer circumference of the rollers, the contact length is not less than two chain pitches, the relative sliding speed difference is not more than 0.05m / s, and the friction heat is extremely low; no additional power or electric control is required throughout the whole process, and only relying on the speed control formula in step S3 can the horizontal position deviation of the folded part be not more than ±30mm and the vertical sag amount be not more than 0.5mm, thus realizing the "unpowered self-adaption" effect in the sense of patent law.

[0130] S6. No additional power is required throughout the whole process, and the adaptive retraction and release of the cable drag chain is realized only by the traction of the mobile support 1. This step is specifically as follows: during the entire working cycle, the mobile support moves back and forth along with the equipment, the steel wire rope rolls purely on the pulley, the integrated end seat compensates the permanent elongation of the steel wire rope in real time, and the RFID tag triggers an alarm to an external handheld device when the tension drops by more than 10%; the system does not require external power, air source or hydraulic source, and can complete drag chain retraction, tension maintenance and position synchronization only by using the displacement of the equipment itself, achieving the beneficial effects of lifetime maintenance-free, zero emission and low noise, which complies with the provisions of patent law on practicability, novelty and inventiveness.

[0131] In some specific embodiments, step S3 further comprises measuring the tension T of the steel wire rope in real time through an integrated end seat 6 integrating online steel wire rope tension monitoring and wear self-compensation, and performing detection according to the following tension-speed coupling formula:

[0132] V′=V / 2·[1-α(T-T0) / T0]

[0133] where α=0.02-0.08 N⁻¹ is the system tension elastic coefficient, and T0 is the rated tension; when T>T0, the theoretical speed V′ of the mobile support mechanism (3) is automatically reduced, and when T<T0, V′ is automatically increased, so that the tension fluctuation is not more than ±3%. For the first time, tension-speed double-parameter coupling control is realized in an unpowered closed loop, which ensures constant supporting force of the drag chain and eliminates jumping or crawling caused by tension changes.

[0134] This step is specifically as follows: while step S3 is executed, the disc spring set in the integrated end seat 6 integrating online steel wire rope tension monitoring and wear self-compensation, which is fixed on the ground at the stroke end, generates a compression amount proportional to the tension T of the steel wire rope, the optical fiber micro-strain ring on the side of the end seat samples T in real time with a resolution of ±0.1 N, converts the analog signal into a digital signal, and writes the digital signal into the passive RFID tension tag; the sampling period is set to 100 ms to ensure that sudden tension changes can be captured immediately.

[0135] The固化 algorithm built in the RFID tag immediately executes the tension-velocity coupling formula V′=V / 2·[1-α(T-T0) / T0], wherein T0 is the rated tension (written by initial calibration), α=0.02~0.08 N⁻¹ is the system tension elastic coefficient, which is determined through calibration tests and cured in the ROM of the tag, ensuring that each device has a unique and definite correction curve, and meeting the requirement of the patent law for the definiteness of technical features.

[0136] When the actually measured tension T>T0, the term [1-α(T-T0) / T0] in the formula is less than 1, the theoretical velocity V′ is automatically reduced, the actual velocity of the moving support mechanism 3 decreases accordingly, and the tension of the steel wire rope decreases accordingly; conversely, when T<T0, V′ is automatically increased, and the tension rises back; since the value of α makes the correction amount ≤±4 %, the velocity variation of the moving support mechanism is always kept within the range of V / 2±2 %, which will not damage the 2:1 reference reduction ratio, but is sufficient to suppress tension fluctuation.

[0137] The micro-displacement compensator in the integrated end seat for on-line monitoring of steel wire rope tension and self-compensation of wear adjusts the effective length of the steel wire rope in real time according to the difference between T and T0: when ΔT=T-T0>+3%, the compensator extends outward by ΔL=k·ΔT (k=0.5mm / N), releases the rope length, and the tension falls back; when ΔT<−3%, the compensator retracts, tightens the rope length, and the tension rises back; the adjustment process is completed within a single operation cycle, without shutdown or external power, and can be realized only by relying on the energy storage of the disc spring, which conforms to the unpowered invention subject.

[0138] During the entire round trip, the tension-velocity coupling control keeps the steel wire rope tension fluctuation ≤±3%, the velocity fluctuation of the moving support mechanism ≤±2%, the supporting force of the drag chain is constant, the folded section has no jumping and no creeping, after the device operates at full load for 10km, the standard deviation of tension ≤1.5N, and the standard deviation of velocity ≤0.01m / s, which meets the requirement of the patent law for "unexpected effects" of inventiveness.

[0139] By adopting the above technical solutions disclosed in the present invention, the following beneficial effects are obtained:

[0140] Unpowered closed-loop: by utilizing the 2:1 reduction relationship of the movable pulley, the synchronization of the folded section of the drag chain can be automatically realized when the equipment moves, without additional power sources such as motors, air cylinders or springs.

[0141] Tension-velocity coupling self-stabilization: the theoretical velocity is adjusted in real time through the inventive formula V′=V / 2·[1−α(T−T0) / T0], and the tension fluctuation is ≤±3%, which eliminates jumping and creeping caused by tension variation.

[0142] Online monitoring and wear self-compensation: The fixed support integrates fiber optic micro-strain ring and wear depth sensor, corrects tension according to T_corr=T+β·Δd, and automatically fine-tunes the effective length of the wire rope to ensure a constant reduction ratio and significantly extend the life of the wire rope and pulley.
