Description

Technical Field

[0001] This invention relates to the field of steel rolling auxiliary equipment technology, and in particular to a steel strip traction device and its usage method. Background Technology

[0002] On cold rolling continuous annealing or coating production lines, strip steel (also known as steel strip) may sometimes break due to scheduled maintenance or other abnormal situations (such as production stoppage due to material shortage). After the scheduled maintenance or abnormal handling is completed, in order to resume production, a traction head for strip steel (steel strip) needs to be made to complete the strip threading operation of the unit.

[0003] In the prior art, patent application number 201721258690.6 discloses a traction head for ultra-thin strip steel; the traction head is made with the assistance of a flat iron with rope holes; during manufacturing, the cut ends of the strip steel are first trimmed evenly, then the trimmed part of the strip steel is folded in half, the folded double-layer strip steel is hammered flat, holes are drilled in the two layers of strip steel according to the position of the rope holes on the flat iron, and the two layers of strip steel are cut into trapezoids; then the flat iron is sandwiched between the two layers of strip steel and the two layers of strip steel are fixed with strong adhesive tape. Together; finally, the rope is fixed by using the holes punched on the double-layer strip steel and the rope holes on the flat iron, thus completing the production of the traction belt head; by setting the two rope holes on the flat iron close to the end of the flat iron and ensuring that the distance between the two rope holes is far, the force on both sides is even during the traction process of the rope, which can reduce the twisting phenomenon of the belt head when passing through (especially when the distance between the two rollers to be passed through is long), and prevent the edge of the belt head from colliding with the equipment when passing through narrow spaces such as electrode plates and hot air drying ovens.

[0004] While the above solution can reduce the probability of belt tip twisting during passage and thus lower the risk of collision due to the more uniform force distribution during traction, cutting the belt tip into a trapezoidal shape can still cause twisting and deformation of the two ends due to pressure if the angle of the pulling force is slightly off, or even scratch the rollers, resulting in significant economic losses. Moreover, the operation process is cumbersome and complex, requiring multiple trimmings and frequent handling of the belt tip, resulting in high labor intensity and relatively high risk (the belt body is thin and the edges are sharp, posing a high risk of scratching during handling), which is not conducive to safe operation.

[0005] Therefore, there is a need for a steel belt traction device that is relatively simple and convenient to use, requires virtually no trimming of the belt head, has low operational risks, and requires little labor intensity. Summary of the Invention

[0006] This application provides a steel belt traction device that solves the technical problems of cumbersome and complex operation, high labor intensity, and high risk in the prior art. It achieves the technical effect of making the steel belt traction device relatively simple and convenient to use, basically eliminating the need for trimming the belt head, and reducing the risk and labor intensity of operation.

[0007] This application provides a steel belt traction device, including a positioning bar, an end flexible bar, a head positioning accessory, a covering cloth, and a pull rope assembly;

[0008] The positioning bar is fitted with a protective sleeve, including a basic telescopic bar that can be lengthened as needed and bar end blocks positioned at both ends of the basic telescopic bar;

[0009] The flexible end rod is longer than 6 cm, made of rubber, horizontally set, and there are two of them, each with one end positioned on one of the rod end blocks;

[0010] The head positioning accessory is covered with a protective sleeve and includes a base plate, an upper cover plate, and a plate assembly.

[0011] The base plate is horizontally arranged, with one side closely attached to and positioned on one side of the base telescopic rod, and at least two top protrusions on the top surface;

[0012] The bottom surface of the upper cover plate is provided with a matching strip that is adapted to the top protrusion strip; after the upper cover plate covers the base plate, the plate assembly will fix the two together near the positioning strip rod, thereby clamping and fixing the stacked steel strip sandwiched between the two; one side of the upper cover plate is fixed near the center of the covering cloth.

[0013] The covering fabric covers the steel strip near the head of the strip before the steel strip is stacked;

[0014] The pull rope assembly is positioned in a Y-shape at the non-fixed end of the flexible rod and is used to apply tension.

[0015] Furthermore, the pull rope assembly includes a combination rope, a positioning block, and a force-applying rope;

[0016] The number of the combined ropes is two, one end of which is fixed to the end of the flexible rod away from the positioning bar; the other end of the combined ropes is fixed to the positioning block.

[0017] The positioning block is a rubber block or a hard block covered with a soft rubber layer, which serves to connect and fix the parts.

[0018] One end of the force-applying rope is fixed to the positioning block, and its length is more than 3 meters;

[0019] In use, the tension rope is first passed through the gap between the rollers, and then the tension is transmitted to the positioning bar through the combined rope by pulling the tension rope, thereby driving the steel belt to move.

[0020] Furthermore, a rope end rod is positioned at the end of the force-applying rope away from the positioning block; the rope end rod is a flexible rubber rod.

[0021] Furthermore, it also includes a first auxiliary rod and a second auxiliary rod;

[0022] Both the first auxiliary rod and the second auxiliary rod are rigid long rods, with a length greater than the width of the steel strip to be processed; the first auxiliary rod is used to assist in arranging the covering fabric; one end of the second auxiliary rod is equipped with an electric or manual gripper, which can clamp the end of the steel strip as needed.

[0023] Preferably, it also includes protective components;

[0024] The protective assembly includes two flexible core rods, a first covering strip, and a second covering strip;

[0025] The flexible core rod is a strip-shaped rod made of rubber, with one end rotatably connected to the end of the flexible rod furthest from the end block, and its length is greater than 60 centimeters;

[0026] Two flexible core rods are respectively positioned on two rod end blocks and rotate around their own axes;

[0027] The first covering tape is a rectangular tape, with both ends wound and positioned on two soft core rods respectively;

[0028] The second covering tape is a rectangular tape; the first and second covering tapes are positioned with Velcro; the presence of Velcro allows the first covering tape, which is wound on the soft core rod, to fit more tightly, and the second covering tape can be glued and fixed to the first covering tape as needed.

[0029] Furthermore, the width of the first covering strip is greater than 60 centimeters, and its length is more than 1.3 times the width of the steel strip to be treated;

[0030] The second covering strip is wider than 40 cm and its length is more than 1.3 times the width of the steel strip to be treated.

[0031] Preferably, it also includes a bootloader component;

[0032] The guiding assembly is fixed to the end of the rope end rod away from the force-applying rope, and includes a bearing plate and two guiding units;

[0033] The bearing plate is a rigid plate covered with an anti-collision rubber layer. One side is positioned at the end of the rope end rod away from the force-applying rope, and two guide units are positioned on the opposite side.

[0034] The two guide units are symmetrically arranged, one above the other, and have the same structure.

[0035] The guiding unit is plate-shaped. The two guiding units move closer or further apart under the combined action of magnetic force and elastic force, thereby adjusting their posture to facilitate passage.

[0036] Furthermore, the guiding unit includes a connecting flexible strip, a C-shaped frame, a carrier roller, an outer outer belt, an adsorption magnet, and a limiting pin;

[0037] The connecting flexible strip is a horizontally placed rubber strip, with one side fixed to the bearing plate;

[0038] The C-shaped frame is arranged laterally, with the side away from the end fixed to the side of the connecting flexible strip away from the bearing plate;

[0039] The axial direction of the carrier roller is perpendicular to the axial direction of the rope end rod;

[0040] A guide unit includes two carrier rollers, both of which are rotatably connected to the C-shaped frame;

[0041] The outer sleeve is fitted onto two carrier rollers and is always kept taut;

[0042] The adsorption magnet is an electromagnet, which is fixed on the C-shaped frame;

[0043] The limiting pin is a horizontally placed electric pin that is controlled to extend and retract, and is positioned within the bearing plate;

[0044] The connecting flexible strip has a through hole for the limiting pin to pass through; the surface of the C-shaped frame near the connecting flexible strip has an insertion hole for the limiting pin to enter.

[0045] Preferably, the U-shaped frame is inclined and fixed to the connecting flexible strip;

[0046] When the connecting flexible strip is in a horizontal state, the inner diameter of its inner through hole is more than 1.3 times the outer diameter of the pin body of the limiting pin;

[0047] The axis of the insertion hole is parallel to the top and bottom surfaces of the U-shaped frame;

[0048] The inner diameter of the insertion hole is 2 to 4 millimeters larger than the outer diameter of the pin body of the limiting pin;

[0049] Once the limiting pin is inserted into the through hole, it will affect the ease with which the U-shaped frame rotates;

[0050] When the limiting pin is retracted, the two guide units are arranged in a figure-eight shape; the length of the insertion hole is greater than 3 cm; during use, as the limiting pin is gradually inserted into the insertion hole, the inserted C-shaped frame will gradually become straight due to pressure.

[0051] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0052] This invention provides a steel strip traction device comprising a positioning bar, two flexible end rods positioned on the side of the positioning bar near both ends, a plate-shaped strip head positioning accessory located between the two flexible end rods, a covering cloth, and a pull rope assembly positioned at the ends of the flexible end rods. During assembly, the covering cloth covers the strip head and the steel strip near the strip head, and the strip head positioning accessory clamps and fixes the folded steel strip near the strip head onto the positioning bar. During dragging, the tension of the pull rope assembly is transmitted to the positioning bar, indirectly dragging the steel strip. When passing through roller gaps, both the flexible end rods and the covering cloth provide protection. This effectively solves the technical problems of cumbersome and complex operation, high labor intensity, and high risk in existing steel strip traction devices. It achieves the technical effects of a relatively simple and convenient steel strip traction device, requiring virtually no strip head trimming, low operational risk, and low labor intensity.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0072] Example 1

[0073] like Figures 1 to 4 As shown, the steel belt traction device of this application includes a positioning strip rod, an end flexible rod 200, a head positioning accessory, a covering cloth 400, a pull rope assembly, a first auxiliary rod 600, and a second auxiliary rod 700.

[0074] The positioning strip is a rigid straight rod, including a basic telescopic rod 110 and rod end blocks 120. The basic telescopic rod 110 is a rigid telescopic rod that can extend and retract at both ends as needed to adjust its overall length. The rod end blocks 120 are rigid blocks, two in number, positioned at both ends of the basic telescopic rod 110, used to support the positioning end flexible rod 200. Both the basic telescopic rod 110 and the rod end blocks 120 are covered with soft protective sleeves, preferably made of rubber, to prevent direct collision between the positioning strip and the roller.

[0075] Furthermore, the basic telescopic rod 110 includes a base pipe and two sliding rods that pass through the base pipe and slide along the axial direction of the base pipe; the two sliding rods are respectively set near both ends of the base pipe, and the sliding rods are dragged as needed to adjust the total length of the basic telescopic rod 110 during use; a bolt is positioned on the base pipe and passes through the base pipe in a direction perpendicular to the axis of the base pipe. The bolt is threaded to the base pipe, and the sliding rod is restricted from sliding when the bolt abuts against and compresses the sliding rod.

[0076] Preferably, the rod end block 120 is a cylindrical block, with its axis perpendicular to the axis of the base telescopic rod 110, and after the base telescopic rod 110 is placed on the steel strip 001, the axis of the rod end block 120 is parallel to the ground.

[0077] The flexible end rod 200 is rod-shaped, longer than 6 cm, made of rubber, horizontally positioned, and its length direction is perpendicular to the length direction of the positioning strip rod. One end is positioned on the rod end block 120. There are two flexible end rods 200, each corresponding to a rod end block 120. The ends of the flexible end rods 200 that are away from the rod end block 120 are relatively sharp. After the positioning strip rod is placed on the steel strip 001 and before the positioning strip rod is inserted between the rollers, the ends of the flexible end rods 200 that are away from the rod end block 120 are relatively closer to the rollers.

[0078] The belt head positioning accessory is used to press and fix the steel strip 001 close to the belt head, thereby assisting the belt head to pass between the rollers; the belt head positioning accessory includes a base plate 310, an upper cover plate 320 and a plate assembly;

[0079] The base plate 310 is a rigid rectangular plate, horizontally positioned, with a thickness of less than 0.6 cm, a width of less than 5 cm, and a length that is one-third to one-half the length of the positioning strip. Its length direction is the same as that of the positioning strip, and one side is tightly attached to and positioned on one side of the base telescopic rod 110. After the positioning strip is placed on the steel strip 001 and before it passes between the rollers, the base plate 310 is closer to the rollers than the positioning strip. The top surface of the base plate 310 has at least two top protrusions 311. Each top protrusion 311 is a rigid strip with a semi-circular longitudinal section. The top protrusions 311 are parallel to each other and parallel to the base telescopic rod 110, with a spacing of 1 to 3 cm between them.

[0080] The upper cover plate 320 is a rigid rectangular plate that is fixed horizontally on the base plate 310. One or more matching strips 321 are provided on its bottom surface. Each matching strip 321 is a rigid long strip, parallel to the base telescopic rod 110, and is adapted to the top protrusion 311 of the plate. There are one or more matching strips. After the base plate 310 and the upper cover plate 320 are fixed together, the matching strips 321 will press the steel strip 001, which is covered by the covering fabric 400, into the gap between the top protrusions 311, thereby fixing the head of the steel strip 001. The side of the upper cover plate 320 furthest from the plate assembly is fixed to the covering fabric 400 near its center.

[0081] The plate assembly is a combination of bolts and threaded holes or a snap-fit ​​structure, used to fix the base plate 310 and the upper cover plate 320 together; the plate assembly is located near the positioning strip rod.

[0082] After the upper cover plate 320 covers the base plate 310, the plate assembly fixes the two together near the positioning strip bar, thereby clamping the base plate 310 and the upper cover plate 320 and fixing the head of the steel strip 001.

[0083] Both the base plate 310 and the top cover plate 320 are provided with soft protective sleeves.

[0084] The length of the flexible end rod 200 is more than 3 centimeters greater than the width of the upper cover plate 320.

[0085] Furthermore, the base plate 310 is directly fixed to one side of the base telescopic rod 110.

[0086] The covering cloth 400 is a rectangular cloth with a length that is more than 1.3 times the width of the steel strip 001 to be processed. It is preferably a scratch-resistant cloth, used to cover the head of the steel strip 001 in a timely manner to prevent it from injuring the operator and scratching the roller. At the same time, it can also enhance the fixing effect of the head positioning accessories on the head of the steel strip 001.

[0087] The pull rope assembly is positioned at the end of the flexible rod 200 away from the positioning bar, and is used to apply a pulling force to the flexible rod 200 to pull the positioning bar and thus pull the steel strip 001 through the roller gap.

[0088] The pull rope assembly includes a combination rope 510, a positioning block 520, and a force-applying rope 530;

[0089] The number of the combined ropes 510 is two, one end of which is fixed to the end of the flexible rod 200 away from the positioning bar; the other end of the combined ropes 510 is fixed to the positioning block 520.

[0090] The positioning block 520 is a rubber block or a hard block covered with a soft rubber layer, which serves to connect and fix the parts.

[0091] One end of the force-applying rope 530 is fixed to the positioning block 520, and its length is more than 3 meters;

[0092] In use, the force is first passed through the gap between the rollers using the force rope 530, and then the tension is transmitted to the positioning bar through the combination rope 510 by pulling the force rope 530, thereby driving the steel strip 001 to move.

[0093] Furthermore, the length of the combined rope 510 is greater than 3 meters.

[0094] Furthermore, in order to facilitate the application of the force rope 530 through the gap between the rollers, a rope end rod 540 is positioned at the end of the force rope 530 away from the positioning block 520; the rope end rod 540 is a rubber flexible rod.

[0095] The first auxiliary rod 600 and the second auxiliary rod 700 are both rigid long rods, with a length greater than the width of the steel strip 001 to be processed; the first auxiliary rod 600 is used to assist in arranging the covering cloth 400; one end of the second auxiliary rod 700 is equipped with an electric or manual gripper, which can clamp the head of the steel strip 001 as needed.

[0096] Furthermore, such as Figure 5 As shown, a soft steel wire mesh (soft steel wire mesh) is fixed on one or both sides of the covering fabric 400. The presence of the soft steel wire mesh can further enhance the anti-slip effect of the covering fabric 400.

[0097] Preferably, the soft wire mesh on the covering fabric 400 is made of ferromagnetic material; the second auxiliary rod 700 has a magnet at one end with a gripper and / or the other end; in use, the covering fabric 400 can be conveniently arranged using the magnet on the rod.

[0098] When the steel belt traction device of this application embodiment is used, such as Figure 6 As shown, the steps are as follows:

[0099] 1. First, adjust the length of the base telescopic rod 110 according to the width of the steel strip 001 to be processed, so that the base telescopic rod 110 is the same length as the steel strip 001 to be processed; if the end of the steel strip 001 has a sharp acute angle (less than 60 degrees), the end of the steel strip 001 needs to be roughly trimmed (the probability of this is very small and there is no need to trim it evenly); then place the positioning strip horizontally on the steel strip 001 near the end, so that the length direction of the positioning strip is the same as the width direction of the steel strip 001, and the positioning strip is 30 to 50 cm away from the end of the steel strip 001;

[0100] 2. Pass the end of the pull rope assembly furthest from the positioning bar through the gap between the rollers and straighten the pull rope assembly;

[0101] 3. With the help of the first auxiliary rod 600 or the second auxiliary rod 700 or by manual adjustment, the positions of the two combined ropes 510 are adjusted so that the combination of the two combined ropes 510 is in a U-shape, so that the rope assembly is no longer pressing on the steel strip 001 so that the end of the strip can be covered by the covering cloth 400.

[0102] 4. Using the second auxiliary rod 700, lift (raise) the head of the steel strip 001. Using the first auxiliary rod 600, wrap about half of the covering fabric 400 around it and fill it under the steel strip 001 and flatten it (at least so that the covering fabric 400 is filled under the base plate 310 at this time). Then flatten the other half of the covering fabric 400 so that it covers the steel strip 001 near the head. At this time, the side of the upper cover plate 320 with the matching strip 321 faces upward and the upper cover plate 320 is set close to the head of the steel strip 001.

[0103] 5. Fold the edge of the covering fabric 400 manually or with the help of the second auxiliary rod 700 so that the edge of the covering fabric 400 is above the steel strip 001, thereby completely covering the head of the steel strip 001;

[0104] 6. Lift the upper cover plate 320, and bend the steel strip 001 wrapped with the cloth 400 between the upper cover plate 320 and the positioning strip rod multiple times and stack it on top of the base plate 310. Use the upper cover plate 320 to press down the steel strip 001 and the cloth 400 stacked on the base plate 310. Then use the plate assembly to fix the base plate 310 and the upper cover plate 320 together and clamp the end of the steel strip 001. After the operation is completed, it is necessary to ensure that the steel strip 001 between the upper cover plate 320 and the base plate 310 does not protrude more than 3 cm from the side away from the positioning strip rod.

[0105] 7. Apply pressure to the stacked steel strips 001 located on both sides of the head positioning accessory to flatten them and avoid affecting dragging;

[0106] 8. Apply tension to the pull rope assembly, pulling the belt through the gap between the rollers.

[0107] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0108] This invention solves the technical problems of cumbersome and complex operation, high labor intensity, and high risk in the operation of existing steel belt traction devices; and achieves the technical effect of relatively simple and convenient use of steel belt traction devices, basically no need to trim the belt head, low risk of operation, and low labor intensity.

[0109] Example 2

[0110] Considering that the lead roller travels between roller group 002 (a combination of two rollers, one above and one below), if Figure 7 As shown, a slight deviation in the angle of the applied tension may cause the edge of the steel strip 001 near the head to be closer to the roller end, which may easily lead to the steel strip 001 near the head being squeezed and deformed, or even deformed and scratching the roller surface, resulting in unnecessary losses. In order to further improve the practicality of this application and reduce the risk of damage to the steel strip and roller, this application embodiment adds a protective component to the above embodiment; while maintaining the applicability of the steel strip traction device to steel strips 001 of different widths, the risk of damage to the roller, steel strip 001 and surrounding components of the roller is reduced, specifically as follows:

[0111] like Figure 8 and Figure 9 As shown, the protective assembly includes two flexible core rods 810, a first covering strip 820, and a second covering strip 830;

[0112] The flexible core rod 810 is a strip-shaped rod made of rubber, with one end rotatably connected to the end of the flexible rod 200 at the far end of the rod end block 120, and a length greater than 60 centimeters; the two flexible core rods 810 are respectively positioned on the two rod end blocks 120 and rotate around their own axes;

[0113] The first covering tape 820 is a rectangular tape with a width greater than 60 cm and a length more than 1.3 times the width of the steel tape 001 to be treated; the two ends of the first covering tape 820 are respectively wound and positioned on two soft core rods 810;

[0114] The second covering tape 830 is a rectangular tape with a width greater than 40 cm and a length more than 1.3 times the width of the steel tape 001 to be processed; the first covering tape 820 and the second covering tape 830 are positioned with sheet-like or strip-like hook and loop fasteners (also known as hook and loop tapes, male and female hook and loop fasteners); the presence of hook and loop fasteners can make the first covering tape 820 wrapped around the soft core rod 810 fit more tightly, and can also stick and fix the second covering tape 830 to the first covering tape 820 as needed;

[0115] During use, when adjusting the length of the positioning strip to fit the steel strip 001, the width of the first covering strip 820 between the soft core rods 810 can be adjusted by winding or releasing the first covering strip 820 wound on the soft core rod 810; when placing the positioning strip, the first covering strip 820 covers the steel strip 001; before the positioning strip is inserted into the gap between the rollers, the second covering strip 830 is inserted to the bottom of the steel strip 001, and then the two ends of the second covering strip 830 are glued and fixed to the top of the first covering strip 820 and kept taut; so that the combination of the first covering strip 820 and the second covering strip 830 covers the steel strip 001, reducing its risk of extrusion deformation and scratches.

[0116] Preferably, both the first covering tape 820 and the second covering tape 830 are anti-scratch fabrics (made of nylon, polyester fiber, etc.).

[0117] Example 3

[0118] Considering that in practical use there is sometimes a need to continuously pass through multiple roller groups 002 (for example, passing through a scale breaking and straightening machine), these roller groups 002 generally have different heights and large height differences. Using only the force rope 530 or rope end rod 540 for passage is difficult and time-consuming. To address these issues, this application embodiment optimizes and improves the structure of the base plate 310 based on the above embodiment and adds a guide component. The guide component, in conjunction with the pull rope component, enables convenient and efficient passage. Specifically:

[0119] like Figure 10 As shown, the base plate 310 is hinged to the base telescopic rod 110 and can rotate relative to the base telescopic rod 110 at an angle of 30 to 60 degrees.

[0120] like Figure 11 and Figure 12 As shown, the guide assembly is fixed to the end of the rope end rod 540 away from the force-applying rope 530, and includes a bearing plate 910 and two guide units;

[0121] The bearing plate 910 is a rigid plate covered with an anti-collision rubber layer. One side is positioned at the end of the rope end rod 540 away from the force-applying rope 530, and two guide units are positioned on the opposite side. The two guide units are symmetrically arranged one above the other and have the same structure.

[0122] The guiding unit includes a connecting flexible strip 920, a zigzag frame 930, a carrier roller 940, an outer outer belt 950, an adsorption magnet 960, and a limiting pin 970;

[0123] The connecting flexible strip 920 is a horizontally placed rubber strip with a rectangular longitudinal section, and one side is fixed to the bearing plate 910;

[0124] The U-shaped frame 930 is a rigid frame in the shape of a U-shape, covered with a rubber layer, and arranged horizontally. The surface away from the end is fixed to the surface of the connecting soft strip 920 away from the bearing plate 910, and is used to support the carrier roller 940.

[0125] The carrier roller 940 is a horizontally arranged rubber roller, with its axial direction perpendicular to the axial direction of the rope end rod 540.

[0126] A guide unit includes two carrier rollers 940, both of which are rotatably connected to the convex frame 930. The distance between the two carrier rollers 940 is greater than four times their own diameter. They are parallel to each other and are respectively positioned close to the ends of the convex frame 930 and the connecting flexible strip 920. The diameter of the carrier rollers 940 is greater than the thickness of the convex frame 930.

[0127] The outer sleeve 950 is an annular tubular belt that is fitted onto two carrier rollers 940 and is always taut.

[0128] The adsorption magnet 960 is an electromagnet, fixed on the shaped frame 930 and located in the space enclosed by the outer strap 950; it is controlled to be powered on and off, thereby cooperating with the connecting soft strip 920 to control the two guide units to move closer or further apart;

[0129] The limiting pin 970 is used to restrict the rotation of the shaped frame 930 relative to the support plate 910. It is a horizontally placed electric pin that is controlled to extend and retract and is positioned within the support plate 910.

[0130] The connecting flexible strip 920 is provided with a through hole 921 for the limiting pin 970 to pass through; the surface of the C-shaped frame 930 near the connecting flexible strip 920 is provided with an insertion hole 931 for the limiting pin 970 to enter; both the through hole 921 and the insertion hole 931 are adapted to the limiting pin 970; the limiting pin 970 in the extended state is in clearance fit with the through hole 921 and the insertion hole 931;

[0131] The operation of the adsorption magnet 960 and the extension and retraction of the limiting pin 970 are both controlled by a remote control.

[0132] When the rope end of the force rope 530 needs to be passed through multiple sets of rollers continuously, the guide component can be inserted into the gap between the rollers by holding the rope end rod 540. Then, the operator observes and judges the position of the gap between the rollers and adjusts the posture of the guide component to efficiently and quickly insert the guide component into and pass through the gap of the roller group 002. When adjusting the posture of the guide component, the connection soft strip 920 can be bent by the attraction force by controlling whether the limit pin 970 penetrates the through hole 921 (when the limit pin 970 is inserted into the through hole 931, the connection soft strip 920 will be unable to bend due to restriction) and the amount of bending that the guide unit can bend when it is attracted by the attraction force from the adsorption magnet 960 (the amount by which the limit pin 970 is inserted into the through hole 921 will have different restrictions on the connection soft strip 920). If one guide unit is restricted from bending, when the adsorption magnet 960 is energized, another guide unit will bend and come close to the guide unit to form a sharp-angled composition for passage. Using a limit pin 970 in conjunction with an adsorption magnet 960 to control the bending of the guiding unit can result in a smaller size and is less prone to unnecessary rotation due to compression compared to directly using a motor.

[0133] Preferred, such as Figure 13 and Figure 14 As shown, in order to make the sharp angle formed by the two guide units smaller and more inclined, thus enabling more convenient and efficient passage; the U-shaped frame 930 is inclined and fixed on the connecting flexible strip 920; when the connecting flexible strip 920 is in a horizontal state (without bending), the inner diameter of its inner passage hole 921 is more than 1.3 times the outer diameter of the pin body of the limiting pin 970 (the retractable part of the limiting pin 970); the end of the pin body of the limiting pin 970 is hemispherical; the axis of the passage hole 931 is aligned with the U-shaped frame The top and bottom surfaces of 930 are parallel; the inner diameter of the insertion hole 931 is 2 to 4 millimeters larger than the outer diameter of the pin body (retractable part) of the limiting pin 970; after the limiting pin 970 is inserted into the through hole 921, it will affect the ease of rotation of the cubit frame 930; in the retracted state of the limiting pin 970, the two guide units are arranged in a figure-eight shape; the length of the insertion hole 931 is greater than 3 centimeters; during use, as the limiting pin 970 is gradually inserted into the through hole 931, the inserted cubit frame 930 will gradually tend to be straight due to pressure.

[0134] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
