Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering cables, and in particular to an electric power engineering cable winding device and a winding method thereof. Background Art

[0002] Cable reels used in power engineering are devices designed specifically for handling, storing, and distributing various types of wires and cables. Such devices are very common in power transmission, distribution, building construction, communication networks, and other industries involving a large number of cable applications. They are designed to improve work efficiency, reduce cable damage, ensure safe operation, and facilitate the transportation and management of cables.

[0003] In the prior art, after the cable is wound, it may become loose, causing the cable to be wound, tangled or even thrown out, which will not only damage the cable but also endanger the safety of the operator. Therefore, the winding end of the cable is fixed with a cable tie or a special clamp to ensure the safety and stability of the cable winding state.

[0004] Although corresponding mechanisms are used to prevent the cables from loosening after they are rolled up, the cables may become loose when the binding tape or special clamp is damaged or the cables need to be unwound. At this time, the elastic potential energy stored when the cables are rolled up is released, driving the cables to swing, causing harm to people and objects around them, and may even cause damage to the cables themselves, such as outer sheath wear and internal conductor breakage. Summary of the invention

[0005] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a power engineering cable winding device and a winding method thereof, which are used to solve the problem proposed in the above-mentioned background technology that when the cable becomes loose during winding, it will cause the cable to swing, causing damage to the cable and posing a safety hazard to surrounding personnel.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The cable drum is provided with a protective mechanism for reducing the cable throwing-out amplitude and throwing-out speed; the protective mechanism includes a plurality of connecting shafts arranged along the circumference of the baffle and a protective sleeve sleeved on the connecting shaft; when the free end of the cable is thrown out and the cable contacts the protective sleeve, the throwing-out range of the cable is limited by the plurality of protective sleeves, and the cable throwing-out speed is reduced by the friction between the cable and the protective sleeve; and when the resistance between the cable and the protective sleeve is large, so that the friction between the cable and the protective sleeve is greater than the friction between the protective sleeve and the connecting shaft, the cable drives the protective sleeve to rotate on the connecting shaft to allow the cable to continue to swing.

[0009] Preferably, the baffle is provided with a first driving mechanism for driving multiple connecting shafts to move radially along the winding drum; when the rotating mechanism drives the winding drum to rotate and reel in the cable, the first driving mechanism drives the connecting shafts to move away from the winding drum radially along the winding drum to allow the cable to be reeled in; when the rotating mechanism completes reeling in the cable, the first driving mechanism drives the connecting shafts to move closer to the winding drum radially along the winding drum until the protective cover contacts the cable to clamp the cable.

[0010] Preferably, the first driving mechanism includes a first rotating rod, a second rotating rod and a first linkage mechanism; both ends of the connecting shaft are connected to the baffle plate by sliding grooves along the radial sliding direction of the winding drum, one end of the first rotating rod is coaxially connected to the connecting shaft, the other end of the first rotating rod is hinged to the second rotating rod, and a first torsion spring is arranged at the hinge position between the first rotating rod and the second rotating rod, and the end of the second rotating rod away from the first torsion spring is rotatably connected to the baffle plate through a rotating shaft; the first linkage mechanism is used to drive multiple second rotating rods to rotate along the axis of the rotating shaft.

[0011] Preferably, the first linkage mechanism includes a gear ring, a connecting rod and a first gear; the gear ring rotates coaxially on the baffle, the two gear rings are connected by a connecting rod, the first gear is arranged on a rotating shaft connected to the second rotating rod, and the first gear is meshed with the gear ring.

[0012] Preferably, a positioning mechanism is provided on the baffle; when the gear ring rotates to drive the multiple connecting shafts away from the winding drum, the positioning mechanism is used to lock the position of the gear ring after rotation, so that the connecting shafts maintain a state of being away from the winding drum.

[0013] Preferably, the positioning mechanism includes a ratchet, a pawl and a second driving mechanism; the ratchet is arranged on the gear ring, the pawl is rotatably connected to the baffle, and one end of the handle is adapted to the ratchet; the second driving mechanism is used to drive the pawl to engage or disengage with the ratchet.

[0014] Preferably, a limiting mechanism is provided on the baffle, and the limiting mechanism is used to limit the rotation between the support seat and the baffle or to limit the rotation between the winding drum and the baffle.

[0015] Preferably, the limiting mechanism includes a limiting member slidably connected to the baffle and a second linkage mechanism for driving the limiting member to move along the axial direction of the winding drum; the second linkage mechanism is used to drive the limiting member to be inserted into the first limiting groove or to drive the limiting member to be inserted into the second limiting groove; when the second linkage mechanism drives the limiting member to be inserted into the first limiting groove, it allows the rotation between the support seat and the baffle and limits the rotation between the winding drum and the baffle; when the second linkage mechanism drives the limiting member to be inserted into the second limiting groove, it allows the rotation between the winding drum and the baffle and limits the rotation between the support seat and the baffle.

[0016] Preferably, the second linkage mechanism includes a rack, a second gear and a slider; the rack is an arc-shaped structure, and is coaxially arranged on the inner ring of the gear ring, the second gear is rotatably connected to the baffle, and the rack is meshed with the second gear, the limit member is coaxially inserted into the second gear, a slider is arranged in the second gear, and the slider is slidably connected to the spiral groove on the limit member; when the second gear rotates to drive the slider to rotate, the limit member moves toward the first limit groove or the second limit groove through the cooperation of the spiral groove.

[0017] A winding method for a cable winding device for electric power engineering, comprising the following steps:

[0018] Step 1: Cable drum installation: First, install the cable drum on the support seat, and then use the limit mechanism to limit the rotation between the support seat and the baffle, and allow the take-up drum and the baffle to rotate;

[0019] Step 2, winding and positioning: the winding drum is then driven to rotate through the rotating mechanism to realize the winding of the cable. When the winding is completed, the rotation between the winding drum and the baffle is limited by the limiting mechanism, and the rotation between the support seat and the baffle is allowed. Then, the protective cover is driven to approach the winding drum through the first linkage mechanism until the protective cover contacts the cable, and the cable is clamped and locked by the cooperation of the protective cover and the winding drum.

[0020] Beneficial effects of the present invention:

[0021] By setting up a protective mechanism, when the cable is wound up and the end of the cable accidentally loses the limit fixation, the cable stretches and swings. At this time, the swinging cable contacts the protective cover, and the swinging range of the cable is limited by multiple protective covers to limit the swinging amplitude of the cable during the unfolding process, effectively eliminating the hidden dangers posed to surrounding workers; when the cable swings with a large force, the cable will first contact the protective cover, and the friction between the cable and the protective cover will hinder the swinging of the cable, so as to offset a part of the elastic potential energy stored in the cable, reduce the swinging speed of the cable, and prevent the cable from being damaged by collision due to excessive swinging speed; and when the friction between the cable and the protective cover is greater than the friction between the protective cover and the connecting shaft, the swinging of the cable will drive the protective cover to rotate on the connecting shaft, thereby reducing the sliding friction between the cable and the protective cover, and preventing the cable from being worn;

[0022] By setting the first driving mechanism and the first linkage mechanism, it is possible to drive multiple protective covers to move synchronously closer to or farther from the winding drum; after the winding of the cable is completed, the multiple protective covers can be driven synchronously to move closer to the winding drum through the first torsion spring, so as to automatically clamp the wound cable; when the cable is accidentally loosened, the cable will push the protective cover to move away from the winding drum, thereby increasing the distance between the protective cover and the winding drum, and allowing the cable to be loosely unfolded within a certain range;

[0023] By setting a limit mechanism, the rotation of the baffle can be restricted, and the hexagonal shaft is separated from the first limit groove, allowing the baffle and the winding drum to rotate, which is convenient for the next step of cable winding; after the cable winding is completed, the rotation locking between the winding drum and the baffle can be achieved to prevent the cable from loosening; and when the cable needs to be unwound, the hexagonal shaft can be driven to separate from the first limit groove, so that the winding drum and the baffle can rotate, that is, at this time the winding drum will rotate in coordination with the swinging of the terminal end of the cable, further improving the release speed of the elastic potential energy of the cable and reducing the swinging speed and amplitude of the cable.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-9 as well as Figure 11-12 As shown, a cable winding device for electric power engineering, such as Figure 1-2 and Figure 4 as well as Fig.12As shown, it includes a support base 1, a cable drum 2 and a rotating mechanism 3 installed on the support base 1; the cable drum 2 is rotatably connected to the support base 1, and the rotating mechanism 3 is used to drive the winding drum 21 to rotate; it can be understood that the present application does not limit the specific structure and installation method of the rotating mechanism 3, as long as it can achieve the driving of the winding drum 21 to rotate, for example, a motor 31 installed on the support base 1, and the output end of the motor 31 is coaxially connected to the winding drum 21; the cable drum 2 includes the winding drum 21 and baffles 22 coaxially rotatably arranged at both ends of the winding drum 21, and the baffles 22 are connected to the support base 1;

[0040] A protective mechanism 4 for reducing the cable throwing-out amplitude and throwing-out speed is provided on the cable reel 2; the protective mechanism 4 includes a plurality of connecting shafts 41 arranged along the circumference of the baffle 22 and a protective sleeve 42 sleeved on the connecting shaft 41; when the free end of the cable is thrown out and the cable contacts the protective sleeve 42, the throwing-out range of the cable is limited by the plurality of protective sleeves 42, and the cable throwing-out speed is reduced by the friction between the cable and the protective sleeve 42; and when the resistance between the cable and the protective sleeve 42 is large, so that the friction between the cable and the protective sleeve 42 is greater than the friction between the protective sleeve 42 and the connecting shaft 41, the cable drives the protective sleeve 42 to rotate on the connecting shaft 41 to allow the cable to continue to swing.

[0041] It should be noted that, since the cable will be bent and tightened when it is rolled up, it stores a certain amount of elastic potential energy. When the terminal end of the cable winding is loosened, the elastic potential energy will be converted into kinetic energy, causing the cable to stretch quickly and form a swinging phenomenon; therefore, when the cable is completely rolled up and the terminal end of the cable winding is loosened, the cable will stretch and swing. At this time, the swinging cable contacts the protective cover 42, and the swinging range of the cable is limited by multiple protective covers 42, so as to limit the swinging amplitude of the cable during the unfolding process, and effectively eliminate the safety hazards posed to the surrounding workers;

[0042] When the cable is unfolded and swung, if the cable swing force is large, the cable will first contact the protective cover 42, and the friction between the cable and the protective cover 42 will hinder the swinging of the cable, so as to offset a part of the elastic potential energy stored in the cable, reduce the swinging speed of the cable, and prevent the cable from being damaged by collision due to excessive swinging speed; and when the friction between the cable and the protective cover 42 is greater than the friction between the protective cover 42 and the connecting shaft 41, the swinging of the cable will drive the protective cover 42 to rotate on the connecting shaft 41, thereby reducing the sliding friction between the cable and the protective cover 42, and preventing the cable from being worn;

[0043] During the cable unwinding process, when the starting end of the cable winding separates from the winding drum 21, the cable may also swing. At this time, the swinging amplitude of the cable can also be limited by the protection mechanism 4, effectively eliminating the hidden dangers to the surrounding staff.

[0044] like Figure 1-3 as well as Fig.11 As shown, a first driving mechanism 43 is provided on the baffle 22 for driving multiple connecting shafts 41 to move radially along the winding drum 21; when the rotating mechanism 3 drives the winding drum 21 to rotate and reel in the cable, the first driving mechanism 43 drives the connecting shafts 41 to move away from the winding drum 21 radially along the winding drum 21 to allow the cable to be reeled in; when the rotating mechanism 3 completes reeling in the cable, the first driving mechanism 43 drives the connecting shafts 41 to move closer to the winding drum 21 radially along the winding drum 21 until the protective cover 42 contacts the cable to clamp the cable.

[0045] It should be noted that when it is necessary to reel in the cable, the first driving mechanism 43 is first used to drive the connecting shaft 41 to move away from the reel 21 in the radial direction of the reel 21, thereby increasing the distance between the reel 21 and the connecting shaft 41. At this time, more cable can be reeled in; when reeling in or unreeling, the cable passes through the space between two adjacent protective sleeves 42, and the reel 21 is driven to rotate (that is, the baffle 22 remains stationary), thereby preventing the provided protective sleeve 42 from interfering with the reeling and unreeling of the cable; and when the reeling of the cable is completed, the first driving mechanism 43 is used to drive the connecting shaft 41 to move closer to the reel 21 in the radial direction of the reel 21 until the protective sleeve 42 contacts the cable, and the protective sleeve 42 cooperates with the reel 21 to clamp and fix the reeled cable and the terminal end of the cable winding, thereby improving the cable reeling stability and preventing the cable from becoming loose during transportation and movement; and when the cable becomes loose accidentally, the cable can still be clamped by providing multiple protective sleeves 42 to prevent the cable from completely loosening and unfolding.

[0046] like Figure 1 and Figure 3 as well as Fig.11 As shown, the first driving mechanism 43 includes a first rotating rod 432, a second rotating rod 433 and a first linkage mechanism 434; both ends of the connecting shaft 41 are connected to the baffle 22 through a slide groove 431 along the radial sliding of the winding drum 21, one end of the first rotating rod 432 is coaxially connected to the connecting shaft 41, the other end of the first rotating rod 432 is hinged to the second rotating rod 433, and a first torsion spring is arranged at the hinge position between the first rotating rod 432 and the second rotating rod 433, and the end of the second rotating rod 433 away from the first torsion spring is connected to the baffle 22 through a rotating shaft; the first linkage mechanism 434 is used to drive multiple second rotating rods 433 to rotate along the axis of the rotating shaft.

[0047] It should be noted that before the cable is wound up, the first linkage mechanism 434 drives the plurality of second rotating rods 433 to rotate, thereby driving the first rotating rod 432 to move, and under the guidance of the slide groove 431, drives the protective sleeve 42 on the connecting shaft 41 to move away from or approach the winding drum 21, thereby achieving the purpose of adjusting the distance between the protective sleeve 42 and the winding drum 21; and when the rotation of the second rotating rod 433 drives the protective sleeve 42 to move away from the winding drum 21, at this time, due to the rotation between the second rotating rod 433 and the first rotating rod 432, the first torsion spring will be compressed; and when the cable is wound up, when the rotation restriction of the second rotating rod 433 is released, the plurality of protective sleeves 42 can be driven by the first torsion spring to synchronously approach the winding drum 21, thereby achieving automatic clamping of the wound cable;

[0048] When the cable accidentally becomes loose, the cable will push the protective cover 42 to move away from the winding drum 21, increasing the distance between the protective cover 42 and the winding drum 21. At this time, the first torsion spring is compressed, allowing the cable to be loosely unfolded within a certain range until the elastic potential energy driving the cable to unfold is balanced with the elastic potential energy of the first torsion spring preventing the cable from unfolding through the protective cover 42. At this time, the cable is in a stable state where it remains wound and will not stretch or be thrown out.

[0049] like Figure 1 and Figure 3-4 as well as Figure 11-12 As shown, the first linkage mechanism 434 includes a gear ring 4341, a connecting rod 4342 and a first gear 4343; the gear ring 4341 rotates coaxially on the baffle 22, the two gear rings 4341 are connected by the connecting rod 4342, the first gear 4343 is arranged on a rotating shaft connected to the second rotating rod 433, and the first gear 4343 is meshed with the gear ring 4341.

[0050] It should be noted that when it is necessary to adjust the distance between the protective sleeve 42 and the winding drum 21, the connecting rod 4342 is pushed to move, thereby driving the gear ring 4341 to rotate, and the gear ring 4341 drives multiple first gears 4343 to rotate, thereby driving multiple second rotating rods 433 to rotate. Similarly, the rotation of the second rotating rod 433 will drive the protective sleeve 42 and the winding drum 21 to move away from or closer to each other, thereby achieving the purpose of synchronously adjusting the positions of multiple protective sleeves 42.

[0051] like Figure 1 and Figure 3 as well as Fig.11As shown, a positioning mechanism 435 is provided on the baffle 22. It is understandable that the present application does not limit the specific structure and installation method of the positioning mechanism 435. Only a specific structure is provided below for reference. When the gear ring 4341 rotates to drive the multiple connecting shafts 41 away from the winding drum 21, the positioning mechanism 435 is used to lock the position of the gear ring 4341 after rotation, so that the connecting shaft 41 maintains a state of being away from the winding drum 21. The positioning mechanism 435 includes a ratchet 4351, a pawl 4352 and a second driving mechanism. The ratchet 4351 is provided on the gear ring 4341, and the pawl 4352 rotates to connect the connecting shafts 41 to the winding drum 21. On the baffle 22, one end of the handle 4353 is adapted to the ratchet 4351; the second driving mechanism is used to drive the pawl 4352 to engage or disengage with the ratchet 4351; the second driving mechanism is a prior art and its specific structure and installation method are not limited, as long as it can drive the pawl 4352 to rotate, such as the handle 4353 installed on the pawl 4352 and the second torsion spring arranged at the rotation connection between the pawl 4352 and the baffle 22. The handle 4353 can be used to push the pawl 4352 to rotate, and the second torsion spring can be used to push the pawl 4352 to automatically reset and engage with the ratchet 4351.

[0052] It should be noted that, when the first linkage mechanism 434 drives the multiple protective sleeves 42 to move away from the winding drum 21, since the first torsion spring is in a compressed state, when the connecting rod 4342 is released, the first torsion spring will drive the protective sleeve 42 to reset. In order to limit the protective sleeve 42 to a state away from the winding drum 21 and facilitate the cable winding work, it is necessary to lock the state of the first linkage mechanism 434 through the positioning mechanism 435; that is, when the first linkage mechanism 434 drives the multiple protective sleeves 42 to move away from the winding drum 21, the pawl 4352 is engaged with the ratchet 4351 at the corresponding position to prevent the tooth ring 4341 from rotating and resetting. Therefore, the protective sleeve 42 can be maintained away from the winding drum 21, which is convenient for the cable winding work.

[0053] like Figure 4-6 and Fig. 9 as well as Fig.12 As shown, a limiting mechanism 436 is provided on the baffle plate 22, and the limiting mechanism 436 is used to limit the support seat 1 (such as Figure 1The limiting mechanism 436 includes a limiting member slidably connected to the baffle 22 and a second linkage mechanism for driving the limiting member to move along the axis of the winding drum 21; the second linkage mechanism is used to drive the limiting member to be inserted into the first limiting groove 4366 or to drive the limiting member to be inserted into the second limiting groove 4367; when the second linkage mechanism drives the limiting member to be inserted into the first limiting groove 4366, it allows the rotation between the support seat 1 and the baffle 22 and limits the rotation between the winding drum 21 and the baffle 22; when the second linkage mechanism drives the limiting member to be inserted into the second limiting groove 4367, it allows the rotation between the winding drum 21 and the baffle 22 and limits the rotation between the support seat 1 and the baffle 22;

[0054] It can be understood that the present application does not limit the specific structure and installation method of the limit member, as long as the limit member can slide on the baffle 22 along the axial direction of the winding drum 21 and the limit member does not rotate, for example, the hexagonal shaft 4363 is inserted into the baffle 22, and the handle 4353 is slidably connected to the baffle 22 through a hexagonal hole formed on the baffle 22 and compatible with the hexagonal shaft 4363.

[0055] It should be noted that when the cable is wound up, after the cable drum 2 is mounted on the support seat 1, the baffle 22 is rotationally limited by the limiting mechanism 436. At this time, the winding drum 21 and the baffle 22 can rotate, that is, when the gear ring 4341 rotates to drive the protective sleeve 42 and the winding drum 21 away, at this time, as the gear ring 4341 rotates, one end of the limiting member is driven to be inserted into the second limiting groove 4367 through the second linkage mechanism. At this time, the other end of the limiting member is separated from the first limiting groove 4366. At this time, the rotation of the baffle 22 is limited by the limiting member, and the winding drum 21 is allowed to rotate. At this time, the winding drum 21 can be driven to rotate by the rotating mechanism 3 to achieve cable winding;

[0056] When the cable is wound up, as the gear ring 4341 rotates to drive the protective sleeve 42 and the winding drum 21 closer, similarly, one end of the limit member is driven to separate from the second limit groove 4367 through the second linkage mechanism, and the other end of the limit member is plugged into the first limit groove 4366, that is, at this time, the baffle 22 and the support seat 1 are allowed to rotate, and the baffle 22 and the winding drum 21 are restricted. By restricting the rotation between the baffle 22 and the winding drum 21, the wound cable is prevented from becoming loose, ensuring that the cable is in a good winding state.

[0057] like Figure 4-9 as well as Fig.12As shown, the second linkage mechanism includes a rack 4361, a second gear 4362 and a slider 4365; the rack 4361 is an arc-shaped structure, and the rack 4361 is coaxially arranged on the inner ring of the gear ring 4341, the second gear 4362 is rotatably connected to the baffle 22, and the rack 4361 is meshed with the second gear 4362, the limiter is coaxially inserted into the second gear 4362, a slider 4365 is arranged in the second gear 4362, and the slider 4365 is slidably connected to the spiral groove 4364 on the limiter; when the second gear 4362 rotates to drive the slider 4365 to rotate, the limiter moves toward the first limiter groove 4366 or the second limiter groove 4367 through the cooperation of the spiral groove 4364.

[0058] It should be noted that when the gear ring 4341 rotates to drive the protective sleeve 42 away from the winding drum 21, the gear ring 4341 rotates, driving the rack 4361 to move, and the second gear 4362 is driven to rotate through the rack 4361, thereby driving the slider 4365 to rotate, and the hexagonal shaft 4363 is pushed to move through the cooperation of the spiral groove 4364, so that one end of the hexagonal shaft 4363 is inserted into the second limiting groove 4367, so as to limit the rotation of the baffle 22. At the same time, the hexagonal shaft 4363 is separated from the first limiting groove 4366, allowing the baffle 22 to rotate with the winding drum 21, so as to facilitate the next step of cable winding.

[0059] After the cable is wound up, as the driving protective sleeve 42 approaches the winding drum 21, the gear ring 4341 is driven to rotate, and then the second linkage mechanism drives one end of the hexagonal shaft 4363 to be inserted into the first limiting groove 4366 through the gear ring 4341, and the other end of the hexagonal shaft 4363 is separated from the second limiting groove 4367. At this time, since the hexagonal shaft 4363 is separated from the second limiting groove 4367, the cable drum 2 can be removed from the support seat 1. At the same time, by inserting the first limiting groove 4366 into the first limiting groove 4366, the rotation locking between the winding drum 21 and the baffle 22 is achieved to prevent the cable from loosening.

[0060] When the cable needs to be unwound, the gear ring 4341 is pushed to rotate, driving the protective sleeve 42 and the winding drum 21 to move away from each other, thereby increasing the distance between the protective sleeve 42 and the winding drum 21, making it easier to loosen the clamping of the cable and to extend the terminal end of the cable to release its elastic potential energy. At the same time, the rotation of the gear ring 4341 drives the hexagonal shaft 4363 to separate from the first limiting groove 4366, so that the winding drum 21 and the baffle 22 can rotate. That is, at this time, the winding drum 21 will rotate in coordination with the swinging of the terminal end of the cable, further increasing the speed of releasing the elastic potential energy of the cable and reducing the swinging speed and amplitude of the cable.

[0061] It should be noted that the length of the hexagonal shaft 4363 and the depth of the first limit groove 4366 are deep enough, that is, when the protective sleeve 42 moves close to the winding drum 21, the hexagonal shaft 4363 will be inserted into the end of the first limit groove 4366, and when the protective sleeve 42 moves slightly closer to the winding drum 21 from the position farthest from the winding drum 21, the hexagonal shaft 4363 has been separated from the second limit groove 4367, and the other end of the hexagonal shaft 4363 has been inserted into the first limit groove 4366, that is, the cable reel 2 can adapt to the winding and locking work of cables of different lengths and sizes.

[0062] like Figure 1-12 As shown, a winding method of a cable winding device for electric power engineering includes the following steps:

[0063] Step 1: Cable drum installation: first install the cable drum 2 on the support base 1, and then use the limiting mechanism 436 to limit the rotation between the support base 1 and the baffle 22, and allow the take-up drum 21 and the baffle 22 to rotate;

[0064] Step 2, winding and positioning: the winding drum 21 is then driven to rotate through the rotating mechanism 3 to realize the winding of the cable. When the winding is completed, the rotation between the winding drum 21 and the baffle 22 is limited by the limiting mechanism 436, and the rotation between the support seat 1 and the baffle 22 is allowed. Then, the protective cover 42 is driven to approach the winding drum 21 through the first linkage mechanism 434 until the protective cover 42 contacts the cable, and the cable is clamped and locked by the cooperation of the protective cover 42 and the winding drum 21.
