Description

Technical Field

[0001] The present invention relates to the technical field of cable shielding covers, and particularly to a cable shielding cover placement device for live working. Background Art

[0002] A cable shielding cover is made of insulating material and is used to shield live conductors or non-live conductor components. Among live working tools, the shielding cover does not play a main insulation role. It is only applicable to provide insulation shielding or isolation protection when a live working personnel has an accidental short-term collision, that is, when rubbing and contacting. During the daily maintenance and repair of cables, workers need to use cable shielding covers to shield and isolate cables. Therefore, installing cable shielding covers is a necessary measure to ensure the stability of the power grid and the personal safety of maintenance personnel.

[0003] In the existing installation process, such as the Chinese patent with the publication number CN218386424U, it discloses an insulating shielding cover installation tool, which includes two insulating pliers bodies that intersect in the middle and are hinged by a rotating shaft I; each of the insulating pliers bodies includes a pliers head and a handle disposed on both sides of the rotating shaft I. Two rows of convex block groups for adjusting the length of the insulating pliers body are symmetrically arranged on the outer periphery of the handle. Each row of the convex block groups includes several convex blocks arranged at intervals along the length direction of the handle. A groove is provided on one side of each convex block away from the pliers head; a connecting rod is slidably sleeved on the outer side of the handle; the connecting rod is a hollow structure with a closed lower end surface; a spring is fixedly connected to the bottom of the handle, and the other end of the spring is fixedly connected to the inner side of the lower end surface of the connecting rod; two fasteners are symmetrically hinged on both sides of the upper end surface of the connecting rod; the two fasteners can cooperate with the grooves on any two opposite convex blocks to fix the position of the handle; an insulating sheath is sleeved on the outer periphery of the connecting rod. The utility model can adjust the length of the handle of the insulating pliers body.

[0004] In the above-mentioned prior art, the installation is mainly carried out through the insulating pliers body. However, in the above-mentioned prior art, the positioning of the shielding cover during the installation process and the subsequent disassembly are not considered. In the prior art, the shielding cover is only installed and clamped by the pressure of the structure, but the clamping position of the shielding cover is not accurately specified, resulting in difficulty in controlling the clamping area generated when the upper and lower clamping points of the shielding cover are butted. When the clamping area is small, under the influence of outdoor wind and rain environment, it is easy to cause the shielding cover to fall off and injure people. Moreover, the prior art does not have a targeted design for the removal of the shielding cover. Since the position of the buckle of the shielding cover is uncertain after installation (this buckle position may be in any area on the outer circle of the cable), it is difficult for the pliers head in the prior art to stably and quickly remove it. When the buckle position is on the back of the cable, it is difficult for the pliers head to contact the buckle position, greatly increasing the disassembly difficulty. Based on this, there is still room for improvement on the existing technology of loading and unloading the shielding cover. Summary of the Invention

[0005] In order to automate the installation of a cable shielding cover in a live environment, the present application provides a cable shielding cover placement device for live working that can be directly mounted on a cable and is used for installing and disassembling the shielding cover.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The present application adopts a mechanical design with a two-in-one structure for the installation and disassembly of the shielding cover. Compared with the prior art without a disassembly function, the present application has stronger functionality, a wider scope of application, is more convenient to use, and the disassembly module of the present application can accurately position the gap position (snap position, clamping position, connection position) of the shielding cover, and the structural design of the separation component fits the structure between the connection positions of the shielding cover, reducing the difficulty of the separation component initially entering the gap and improving the smoothness of the subsequent disassembly process. At the same time, through the cooperation of the connection component, the linkage component and the arc plate, the purpose of automatically positioning the shielding cover before disassembly is achieved, improving the efficiency and safety;

[0022] 2. The installation module provided in the present application can accurately install the shielding cover. The upper and lower arranged partition plates limit the clamping ends at the upper and lower ends of the shielding cover, so as to achieve the effect of internal snap locking. After the connecting plates are combined, the partition plates retract. At this time, the clamping ends at the upper and lower ends of the shielding cover lose the barrier and are combined and clamped, and under the elastic pressure of the subsequent pressing block two, the clamping position is tightly pressed in a regional manner, so as to achieve the purpose of large-area snap, improving the clamping degree;

[0023] 3. The disassembly module is mainly used to replace the damaged shielding cover. Specifically, by squeezing the right end of the shielding cover, the right end of the clamping position is opened to generate a gap. At this time, the separation component is aligned with the gap, and the electric slider two drives the annular component and the separation component to move left synchronously, so as to expand the gap area and multiply open it, and then obtain the disassembled shielding cover, and then remove and replace it;

[0024] 4. The arc plate, the rotating ring, the linkage component and the connection component adopt a design concept of structural linkage to unlock the position of one of the rotating ring, the arc plate and the linkage component and temporarily lock it with the other, so as to cooperate with the separation component for rotational positioning and horizontal extrusion of the gap.

Detailed implementation manners

[0036] The following further elaborates on this application in conjunction with the attached Figures 1-10 to further explain this application in detail.

[0037] The embodiment of this application discloses a cable shielding cover placement device for live working. Through the design and improvement of the drive module 4 and the disassembly module 7, the functions of installing and disassembling the shielding cover are realized, reducing the frequency of manual operation, and the operation is simple and fast, greatly improving the efficiency and safety in the actual use process.

[0038] Referring to Figures 1-2 As shown in the figure, a metal stretching and straightening integrated machine disclosed in this embodiment includes a mounting rod 1, a housing 2, a mounting cross bar 3, a driving module 4, a mounting module 5, a positioning module 6, and a dismounting module 7. A housing 2 is provided at the front end of the mounting rod 1. A mounting cross bar 3 is fixedly connected to the front end of the housing 2. A driving module 4 is installed inside the housing 2. A mounting module 5 cooperating with the driving module 4 is rotatably arranged on the housing 2. A positioning module 6 is slidably arranged at the front end of the mounting cross bar 3. The positioning module 6 is in cooperative connection with the driving module 4. A dismounting module 7 is arranged inside the positioning module 6. Connecting hooks are symmetrically installed at the left and right ends of the mounting cross bar 3.

[0039] Referring to Figures 1-2 As shown in the figure, the positioning module 6 includes a transmission assembly 61, a merging assembly 62, and a cylinder 63. The cylinder 63 arranged above is connected to the mounting cross bar 3 by a sliding fit. The material of the cylinder 63 is light. A transmission assembly 61 is in cooperative connection between the cylinder 63 arranged above and the driving module 4. The cylinder 63 arranged below is slidably arranged on the merging assembly 62. A metal column 1 with a rubber outer layer is provided at the lower end of the cylinder 63 arranged above. A connecting hole 1 is provided at the upper end of the cylinder 63 arranged below, and the positions of the metal column 1 and the connecting hole 1 correspond. After the cylinders 63 arranged up and down are merged, the positions of the cylinders 63 arranged up and down are temporarily locked by inserting the metal column 1 into the connecting hole 1. And the insertion of the metal column 1 into the connecting hole 1 only serves as a temporary locking function. When separating the cylinders 63 arranged up and down, they can be forcibly separated by simply forcing them apart. At this time, the metal column 1 is disengaged from the connecting hole 1 under the action of an external force. The merging assembly 62 rotatably connected to the housing 2 is in cooperative connection with the driving module 4.

[0040] Referring to Figures 1-4As shown in the figure, the disassembly module 7 includes an annular track 71, an electric slider 72, a connecting block 73, an arc plate 74, a rotating ring 75, a linkage assembly 76, a separation assembly 77, a horizontal track 78, an electric slider 79, an expanding cylinder 80, a blocking block 81, and a connecting assembly 82. The annular track 71 is installed on the inner wall of the cylinder body 63. An electric slider 72 is installed on the annular track 71 arranged above. The electric slider 72 is connected to the arc plate 74 through the connecting block 73, and the arc plate 74 is in an embedded lock with the rotating ring 75 arranged above. The right end of the rotating ring 75 is temporarily inserted horizontally into the cylinder body 63 to ensure that the rotating ring 75 in the initial position will not fall off the cylinder body 63. A linkage assembly 76 is arranged inside the rotating ring 75. A separation assembly 77 is arranged at the upper end of the rotating ring 75 located above. A metal column two wrapped with an elastic material on the outside is arranged at the lower end of the rotating ring 75 located above. The function of the metal column two is the same as that of the metal column one. A connecting hole two is opened at the upper end of the rotating ring 75 located below, and the positions of the metal column two and the connecting hole two correspond. A horizontal track 78 is arranged at the front end of the installation cross bar 3. An electric slider 79 is connected to the horizontal track 78. The front end of the electric slider 79 is connected to a connecting assembly 82. The connecting assembly 82 is in a mating connection with the rotating ring 75. The right end of the cylinder body 63 is fixedly connected to an expanding cylinder 80. A blocking block 81 is rotatably arranged at the left end of the cylinder body 63 located below. The blocking block 81 limits the left end of the rotating ring 75. The blocking block 81 is connected to a receiving groove opened on the cylinder body 63 through a compression spring. The receiving groove serves to hide and receive the blocking block 81 after being squeezed. The number of the annular track 71, the rotating ring 75, and the expanding cylinder 80 is two, and they are arranged vertically. The number of the electric slider 72, the connecting block 73, the arc plate 74, the linkage assembly 76, the separation assembly 77, the horizontal track 78, the electric slider 79, the blocking block 81, and the connecting assembly 82 is one.

[0041] By adopting the above technical solution, during the actual installation process, the connection hook is lapped on the cable, so as to temporarily lock the position of the present application with the cable. Subsequently, the driving module 4 is used to squeeze the installation module 5, and the shielding cover is installed by the up-and-down closing of the installation module 5. Subsequently, the present application is withdrawn from the cable.

[0042] During the actual maintenance process, when it is necessary to disassemble the shielding cover, the connecting hook is lapped on the cable, and the driving module 4 is used to squeeze the merging component 62, so that the vertically arranged cylinders 63, the vertically arranged rotating rings 75, and the vertically arranged expanding cylinders 80 are merged (the merged cylinders 63 form a complete cylinder component, the merged rotating rings 75 form a complete ring component, and the merged expanding cylinders 80 form a complete expanding component). After the merger, the cylinder component, the ring component, and the expanding component are coaxial with the cable. While merging, the blocking block 81 is squeezed by the upper cylinder 63 and retracts into the storage groove. At this time, the blocking block 81 no longer limits the left end of the lower rotating ring 75. Subsequently, the driving module 4 drives the cylinder component and the expanding component to move leftward through the transmission component 61, so as to perform a squeezing and cavity-expanding treatment on the right end of the shielding cover. At this time, a gap is extruded at the clamping connection of the shielding cover. The electric slider 72 drives the arc plate 74 and the ring component to rotate until the separation component 77 is clamped corresponding to the gap of the shielding cover. At this time, the electric slider 79 drives the connecting component 82 to snap into the upper rotating ring 75 to the right. Under the action of the elastic squeezing force and the linkage component 76, the position between the arc plate 74 and the ring component is unlocked. At this time, the connecting component 82 and the ring component are temporarily locked, and the ring component and the arc plate 74 are temporarily separated. Subsequently, the electric slider 79 drives the ring component to move leftward through the connecting component 82. The synchronously moving separation component 77 further pushes and separates the gap position of the shielding cover in a linear manner. When the ring component moves to the leftmost end, the gap of the shielding cover is completely opened, and the connecting component 82 contacts the left side of the merging component 62. At this time, the locking method between the connecting component 82 and the rotating ring 75 changes. Subsequently, the electric slider 79 drives the rotating ring 75 to move rightward to the initial position until the annular component is docked with the arc plate 74 again. At this time, due to the change in the locking method between the connecting component 82 and the rotating ring 75, through the change in the locking method and the cooperation of the linkage component 76, the arc plate 74 and the annular component are re-clamped and locked, and the ring component and the connecting component 82 are re-unlocked. Subsequently, the cylinder component, the ring component, and the expanding component withdraw to the right and expand and reset, and this application is withdrawn from the cable. At this time, the connection position of the shielding cover is opened, and it is removed and replaced.

[0043] Through the special design of the fixture and the transmission mechanism, this application can realize different operations for the installation and disassembly of the shielding cover, and can accurately position the installation position of the shielding cover during the disassembly process, greatly reducing the risks and difficulties brought by high-altitude operations. This application is simple to operate and has a stable structure, which can greatly improve the work efficiency and safety during the actual installation process.

[0044] Refer to Figures 1-2As shown, the driving module 4 provided in the present application can apply power to the mounting module 5, transmission component 61, and merging component 62 at different angles. Specifically, the driving module 4 includes a cylinder 41, a connecting rod 42, a first extrusion block 43, a connecting sleeve 44, a second extrusion block 45, and an adjusting handle 46. The cylinder 41 is fixedly installed in the inner cavity of the mounting rod 1. The extending end of the cylinder 41 is connected to the first extrusion block 43 through the connecting rod 42. The lower inclined surface of the first extrusion block 43 is a structure that gradually rises from back to front. The connecting sleeve 44 is rotatably sleeved on the connecting rod 42. The second extrusion block 45 is installed on the connecting sleeve 44. Chamfer structures are provided on both sides of the front end of the second extrusion block 45. The adjusting handle 46 is installed at the rear end of the connecting sleeve 44, and the adjusting handle 46 can adjust the angle of the second extrusion block 45.

[0045] During the actual installation process, the cylinder 41 drives the first extrusion block 43 and the second extrusion block 45 to move forward through the connecting rod 42. The first extrusion block 43 first squeezes the merging component 62 so that the merging component 62 is closed with the connecting hook lapped on the cable (at this time, the cylinders 63 arranged up and down are in a merged state, but are located on the right side of the shielding cover and do not touch, and will not affect the normal installation of the shielding cover), thereby temporarily lapping and positioning the position of the present application and the cable. The connecting rod 42 continues to move so that the second extrusion block 45 squeezes the mounting module 5, and the mounting module 5 with the upper and lower angles merged sleevingly clamps the shielding cover on the cable. After the installation is completed, during disassembly, the adjusting handle 46 drives the second extrusion block 45 to rotate 90 degrees. At this time, the position between the second extrusion block 45 and the transmission component 61 corresponds. The cylinder 41 drives the connecting rod 42, the first extrusion block 43, and the second extrusion block 45 to move forward. The first extrusion block 43 first squeezes the merging component 62 so that the merging component 62 is closed with the connecting hook lapped on the cable (at this time, the cylinders 63 arranged up and down are in a merged state), thereby temporarily lapping and positioning the position of the present application and the cable. Subsequently, the second extrusion block 45 contacts the transmission component 61, and drives the overall merged cylinder 63 to move to the left under the drive of the transmission component 61.

[0046] Refer to Figures 1-2 、 Figure 5As shown, in order to ensure that the connection position of the shielding cover can be better clamped during the installation process, the present application is provided with an installation module 5. Specifically, the installation module 5 includes a transmission arm 51, a connecting plate 52, a contact block 53, a partition plate 54, a transmission plate 55, a rotating rod 56, a first pressing block 57, and a second pressing block 58. The rear end of the transmission arm 51 that cooperates with the second pressing block 45 is rotatably arranged in the housing 2. The transmission arm 51 is connected to the housing 2 through a first tension spring. The transmission arm 51 is symmetrically arranged up and down. The front end of the transmission arm 51 is provided with a connecting plate 52. A contact block 53 is slidably arranged in the inner cavity opened inside the connecting plate 52. When the vertically arranged connecting plates 52 rotate and close together, the corresponding contact blocks 53 squeeze each other and thus completely retract into the inner cavity. The upper end of the contact block 53 contacts the inclined surface at the lower end of the partition plate 54. The partition plate 54 is connected to the inner cavity through a compression spring. The partition plate 54 can expand and contract in the inner cavity through the extrusion of the contact block 53, realizing the functions of clamping and releasing the shielding cover. The inclined surface at the upper end of the partition plate 54 contacts the lower end of the transmission plate 55. The transmission plate 55 is slidably arranged up and down in the inner cavity. The upper end of the transmission plate 55 cooperates with the rotating rod 56. The rotating rod 56 is rotatably arranged in the inner cavity. The rotating rod 56 is connected to the inner cavity through a first return spring. The telescopic part at the rear end of the rotating rod 56 contacts the first pressing block 57. The first pressing block 57 is slidably arranged in the inner cavity. The lower end of the first pressing block 57 is elastically connected with the second pressing block 58. The protruding second pressing block 58 presses the connection position of the shielding cover in an elastic and opposite direction up and down, thereby improving the clamping degree of the connection position.

[0047] During the actual installation process, the air cylinder 41 drives the second pressing block 45 through the connecting rod 42 to squeeze the transmission arm 51 for angular adjustment in the opposite direction. When the connecting plates 52 installed on the transmission arm 51 are about to close together, the corresponding contact blocks 53 in the vertically arranged connecting plates 52 contact each other, and under the action of the mutual extrusion force, the corresponding partition plates 54 are squeezed, causing the partition plates 54 to gradually retract into the inner cavity. At the same time, the partition plates 54 squeeze the rotating rod 56 to rotate through the transmission plate 55. The first pressing block 57 at the rear end of the rotating rod 56 squeezes the connecting part (open end) of the shielding cover through the second pressing block 58. After the connecting plates 52 are completely closed, the partition plates 54 are completely retracted into the inner cavity, so that the connecting parts of the shielding cover are not blocked by the partition plates 54, and under the elastic extrusion of the protruding second pressing block 58, the upper and lower open ends of the shielding cover are pressed and clamped. At this time, the shielding cover clamping is completed.

[0048] Refer to Figures 1-2As shown, the transmission assembly 61 includes a sliding arm 611, a transmission rod 612, a sliding seat 613, and a moving groove 614. The sliding arm 611 cooperating with the second extrusion block 45 is slidably disposed on the housing 2. The right end of the sliding arm 611 is rotatably connected to the transmission rod 612. The middle of the transmission rod 612 is rotatably disposed in a rotating groove formed in the mounting cross bar 3. The transmission rod 612 is connected to the rotating groove through a second return spring. The second return spring can reset the transmission assembly 61. The front end of the transmission rod 612 is rotatably connected to the sliding seat 613. The sliding seat 613 is slidably disposed in the moving groove 614. The moving groove 614 is formed at the right end of the upper cylinder body 63. The formation of the moving groove 614 ensures the normal left and right movement of the upper cylinder body 63 driven by the transmission assembly 61 during the adjustment process.

[0049] During the actual working process, the cylinder 41 drives the second extrusion block 45 through the connecting rod 42 to extrude the sliding arm 611. The sliding arm 611 drives the sliding seat 613 to move leftward through the transmission rod 612. Since the sliding seat 613 is slidably disposed in the moving groove 614 formed at the right end of the upper cylinder body 63, the cylinder body 63 is driven to move leftward.

[0050] Refer to Figures 1-3 As shown, during the installation process, in order to ensure the relative position fixation between the present device and the cable, the present application is provided with a merging assembly 62, which is in a closed clamping connection with the connecting hook, thereby temporarily positioning the present application and the cable. Specifically, the merging assembly 62 includes a mounting arm 621, a mounting plate 622, and a fixing hook 623. The mounting arm 621 cooperating with the first extrusion block 43 is rotatably disposed in the housing 2. The mounting arm 621 is connected to the housing 2 through a second tension spring. The second tension spring can reset the merging assembly 62. The front end of the mounting arm 621 is provided with a mounting plate 622. The left and right ends of the mounting plate 622 are symmetrically provided with fixing hooks 623. Both the fixing hook 623 and the connecting hook are made of non-conductive materials and can directly contact the surface of the cable. The lower cylinder body 63 is slidably disposed on the mounting plate 622. During the actual working process, the cylinder 41 drives the first extrusion block 43 through the connecting rod 42 to extrude the mounting arm 621. The mounting arm 621 drives the fixing hook 623 to adjust the angle upward through the mounting plate 622 until the two are closed. At this time, the cylinder body 63 (this cylinder body 63 is arranged below) connected to the mounting plate 622 is closed synchronously with the upper cylinder body 63.

[0051] Refer to Figure 4 、 Figure 7As shown, the connection between the arc-shaped plate 74 and the rotating ring 75 is a temporary locking connection. Specifically, the arc-shaped plate 74 includes a clamping plate 741 and a clamping member 742. The clamping plate 741 is installed on the first connecting block 73. A clamping member 742 is slidably arranged in an internal groove opened at the left end of the clamping plate 741. An internal spring is connected between the clamping member 742 and the internal groove, and the internal spring can reset the clamping member 742.

[0052] Referring to Figure 2 、 Figure 4 、 Figure 7 As shown, the rotating ring 75 includes a ring body 751, a first annular groove 752, a second annular groove 753, an inclined groove 754, and a third annular groove 755. The ring body 751 is horizontally inserted into the left end of the cylinder 63, so that the ring body 751 in the initial position will not fall out of the cylinder 63. A first annular groove 752 is opened at the right end of the ring body 751. A clamping groove is opened at the rear end of the first annular groove 752 of the ring body 751 located above, and the clamping groove corresponds to the position of the clamping member 742. A second annular groove 753 is opened at the left end of the ring body 751. A sliding hole is opened between the first annular groove 752 and the second annular groove 753. An inclined groove 754 is opened at the right end of the second annular groove 753 and is communicated with the first annular groove 752. A third annular groove 755 communicated with the first annular groove 752 is opened on the ring body 751.

[0053] In the initial state, the clamping plate 741 extends into the first annular groove 752 in the rotating ring 75. Through the mutual clamping between the protruding clamping member 742 and the clamping groove in the first annular groove 752, the positions of the arc-shaped plate 74 and the ring body assembly are locked, playing a role of temporary locking.

[0054] Referring to Figures 3-4 、 Figure 7 As shown, in order to realize the transformation of the locking relationship between the ring body assembly, the arc-shaped plate 74, and the connecting assembly 82, the cooperation among the arc-shaped plate 74, the linkage assembly 76, the rotating ring 75, and the connecting assembly 82 provided in this application is used to replace the locked position. Specifically, the linkage assembly 76 includes a first sliding rod 761, a working spring 762, a compression plate 763, and an extrusion ring 764. A first sliding rod 761 is slidably arranged in the sliding hole. The first sliding rod 761 is annularly arranged. The first annular groove 752 is connected to the compression plate 763 through the working spring 762. The position of the compression plate 763 corresponds to the position of the clamping plate 741. The compression plate 763 is connected to the extrusion ring 764 through a first connecting rope. The extrusion ring 764 slidably arranged in the third annular groove 755 is connected to the third annular groove 755 through a connecting spring, and the elastic force of the connecting spring is less than the elastic force of the working spring 762.

[0055] Referring to Figures 3-4 、 Figure 7As shown, the connection component 82 includes a second connection block 821, a clamping block 822, a second inclined groove 823, a locking post 824, a sliding groove 825, a second sliding rod 826, and an extrusion groove 827. The second connection block 821 is arranged on the second electric slider 79. A telescopic spring is connected between the hidden groove opened in the second connection block 821 and the clamping block 822. The elastic force of the telescopic spring is greater than that of the built-in spring. The second connection block 821 is provided with a second inclined groove 823 penetrating from left to right, and the second inclined groove 823 is gradually inclined backward from left to right. The locking post 824 is slidably arranged inside the second inclined groove 823. The front end of the second connection block 821 is provided with a sliding groove 825, and the second sliding rod 826 is slidably arranged inside the sliding groove 825. The second sliding rod 826 is connected to the locking post 824 through a second connecting rope. The clamping block 822 is provided with an extrusion groove 827. During the process of the clamping block 822 gradually retracting into the hidden groove, the right end of the locking post 824 is gradually pushed to move leftward by the inclined surface of the extrusion groove 827. When the clamping block 822 is completely retracted into the hidden groove, the right side of the locking post 824 completely exits the extrusion groove 827, and the positions of the first inclined groove 754, the extrusion groove 827, and the second inclined groove 823 correspond to each other.

[0056] During the actual disassembly process, the electric slider two 79 drives the connection component 82 to move to the right, so that the right end of the connection component 82 enters the second annular groove 753. Under the action of the telescopic spring, the clamping block 822 is ejected from the hidden groove, and the clamping part 742 is pushed back into the built-in groove by means of the first sliding rod 761, thus unlocking the position between the arc-shaped plate 74 and the ring body component. At this time, the position between the second connecting block 821 and the ring body component is locked. The electric slider two 79 drives the connection component 82 and the annular component to move to the left synchronously (at the initial stage of moving to the left, the arc-shaped plate 74 disengages from the first annular groove 752. At this time, the compression plate 763 moves to the right under the action of the working spring 762, and drives the extrusion ring 764 to move to the right under the action of the first connecting rope. At this time, the extrusion ring 764 no longer extrudes the second sliding rod 826). The separation component 77 is used to forcibly open the gap of the shielding cover. When the annular component moves to the leftmost side, the locking column 824 is squeezed by the side wall of the connecting hook arranged on the left side and thus completely retracts into the second inclined groove 823. At this time, the right end of the locking column 824 passes through the extrusion groove 827 and enters the first inclined groove 754. At this time, the locking method between the second connecting block 821 and the ring body component changes (the clamping effect between the clamping block 822 and the second annular groove 753 disappears, and the right end of the locking column 824 is currently obliquely inserted into the first inclined groove 754). The change of the locking method does not affect the temporary locking between the second connecting block 821 and the ring body component. The electric slider two 79 drives the connection component 82 and the annular component to move to the right synchronously to the initial position. At this time, the arc-shaped plate 74 re-enters the first annular groove 752 for re-clamping (since the right end of the locking column 824 is inserted into the first inclined groove 754, forcing the clamping block 822 to completely retract into the hidden groove. At this time, the first sliding rod 761 loses the extrusion effect on the clamping part 742. At this time, the clamping part 742 is re-clamped with the clamping groove under the action of the elastic force). The left end of the arc-shaped plate 74 squeezes the compression plate 763. At this time, the first connecting rope is loosened, and the extrusion ring 764 instantaneously extends to the left under the action of the connecting spring and thus squeezes the second sliding rod 826 to move backward. The second sliding rod 826 drives the locking column 824 to move to the left through the second connecting rope and gradually withdraws from the first inclined groove 754 until the right end of the locking column 824 is flush with the right end of the extrusion groove 827 (at this time, the second connecting block 821 and the ring body component are unlocked). At this time, the electric slider two 79 drives the connection component 82 to move to the left to withdraw from the second annular groove 753. (Since the elastic force direction of the telescopic spring on the clamping block 822 and the extrusion direction of the extrusion groove 827 on the locking column 824 are in different orientations, the clamping block 822 slowly pops out. Therefore, it will not instantaneously pop out from the hidden groove immediately when the right end of the locking column 824 is flush with the right end of the extrusion groove 827. It will pop out and reset with a delay after the connection component 82 withdraws from the second annular groove 753. At this time, the right end of the locking column 824 is extruded out of the extrusion groove 827 by the reset pop-up of the clamping block 822).

[0057] Refer toFigures 3-4 , Figures 8-9 As shown in Figures 8-9 , the connection part of the shielding cover is connected in a relatively stable manner. In order to disassemble the connection position (clamping position) of the shielding cover more smoothly, the present application is provided with a separation component 77 that fits the clamping position. Specifically, the separation component 77 includes a metal plate 771, an expansion plate 772, an expansion spring 773, and a contact head 774. The rear end of the π-shaped metal plate 771 is rotatably connected to the expansion plate 772. The π-shaped structure design and the tapered front end of the metal plate 771 enable the metal plate 771 to be smoothly inserted into the shielding cover. An expansion spring 773 is connected between the front and rear arranged expansion plates 772, which can further separate the shielding cover. The front end of the metal plate 771 is elastically provided with a contact head 774, which can accurately position the installation position of the shielding cover.

[0058] During the actual disassembly process, the electric slider one 72 drives the separation component 77 to rotate. After the contact head 774 touches the widened gap part of the shielding cover, the separation component 77 stops rotating. At this time, the metal plate 771 is facing the gap part. The electric slider two 79 drives the ring body component to move leftward. The metal plate 771 with a tapered front end enters the gap and separates the connection part of the shielding cover. The expansion plate 772 moving synchronously with the metal plate 771 opens to both sides under the action of the expansion spring 773, further widening the connection position of the shielding cover for disassembly processing.

[0059] The implementation principle of this embodiment is as follows:

[0060] A. Installation: The connection hook is lapped on the cable, thereby temporarily locking the position of the present application with the cable. Subsequently, the driving module 4 squeezes the installation module 5 and the merging component 62. The fixed hook 623 in the merging component 62 closes with the connection hook, thereby temporarily lapping and positioning the present application with the cable. The shielding cover is installed by the up and down closing of the installation module 5;

[0061] B. Disassembly:

[0062] Step 1: The connection hook is lapped on the cable. The pressing block two 45 is driven to rotate 90 degrees by the adjusting handle 46. At this time, the pressing block two 45 corresponds to the transmission component 61. The driving module 4 squeezes the transmission component 61 and the merging component 62, causing the up and down arranged cylinders 63, the up and down arranged rotating rings 75, and the up and down arranged expanding cylinders 80 to merge. After merging, the cylinder body component, the ring body component, and the expanding component are on the same axis as the cable. While merging, the blocking block 81 is squeezed by the upper cylinder 63 and retracts into the receiving groove. At this time, the blocking block 81 no longer limits the left end of the lower rotating ring 75;

[0063] Step 2: The driving module 4 drives the cylinder assembly and the expanding assembly to move leftward through the transmission assembly 61, so as to perform an extrusion cavity expansion treatment on the right end of the shielding cover. At this time, a gap is extruded at the clamped connection of the shielding cover;

[0064] Step 3: The electric slider 72 drives the arc plate 74 and the ring assembly to rotate until the contact head 774 in the separating assembly 77 is clamped into the gap of the shielding cover. At this time, the ring assembly stops rotating;

[0065] Step 4: The electric slider 79 drives the connecting assembly 82 to be inserted into the upper rotating ring 75 to the right. Under the action of the elastic extrusion force and the linkage assembly 76, the position between the arc plate 74 and the ring assembly is unlocked. At this time, the connecting assembly 82 and the ring assembly are temporarily locked;

[0066] Step 5: The electric slider 79 drives the ring assembly to move leftward through the connecting assembly 82. The synchronously moving separating assembly 77 further pushes and separates the gap position of the shielding cover in a linear manner;

[0067] Step 6: When the ring assembly moves to the leftmost end, the gap of the shielding cover is completely opened, and the locking column 824 in the connecting assembly 82 contacts the fixed hook 623 arranged on the left side. Under the extrusion of the fixed hook 623, the right end of the locking column 824 is obliquely inserted into the inclined slot 754, and the clamping block 822 is forced to retract into the hidden slot due to the extrusion of the locking column 824. At this time, the clamping effect between the connecting block 821 and the annular slot 753 disappears;

[0068] Step 7: The electric slider 79 drives the rotating ring 75 to move rightward and reset to the initial position until the ring assembly is docked and clamped with the arc plate 74 again. At the same time, the arc plate 74 extending into the annular slot 752 presses the compression plate 763. At this time, the connecting rope 1 is loosened, and the extrusion ring 764 instantaneously extends leftward under the action of the connecting spring, thereby pressing the sliding rod 826 to move backward. The sliding rod 826 drives the locking column 824 to move leftward through the connecting rope 2 and gradually withdraw from the inclined slot 754 until the right end of the locking column 824 is flush with the right end of the extrusion slot 827 (at this time, the connection between the connecting block 821 and the ring assembly is unlocked);

[0069] Step 8: The electric slider 79 drives the connecting assembly 82 to move leftward to withdraw from the annular slot 753, and the clamping block 822 extends out with a delay under the action of the telescopic spring;

[0070] Step 9: Control the cylinder assembly, the ring assembly, and the expanding assembly to withdraw to the right and then expand and reset, and withdraw this application from the cable. At this time, the connection position of the shielding cover is opened, and it is removed for replacement.

Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
