Description

Technical Field

[0001] The present application relates to the technical field of electric power equipment, and in particular to an insulator disassembly and assembly auxiliary mechanism and an insulator disassembly and assembly device. Background Art

[0002] In the national power grid system, insulators are widely used in the transmission and distribution of electricity. Insulators are devices installed between conductors of different potentials or between conductors and grounded components. They can withstand voltage and mechanical stress and play a good supporting and insulating role in the power system. In some high-voltage scenarios, insulator strings are used to increase the insulation effect.

[0003] In actual use, since insulators are exposed to the external environment for a long time and are easily affected by external influences such as electric fields or rain, the performance of insulators is easily affected. Therefore, insulators need to be replaced regularly.

[0004] In the related technology, for the replacement of insulators, related manufacturers directly clamp the steel cap through some clamps, and most of these clamps adopt a wrapping method to wrap and clamp the steel cap of the entire insulator. The contact between them is a large-area surface-to-surface contact, and the steel cap is clamped by friction between the surfaces.

[0005] However, this method has the following shortcomings. On the one hand, the friction between the surface of the clamp and the steel cap is not enough to clamp some large steel caps, which may cause the steel caps to slip and fall, thereby causing damage to other parts of the insulator. On the other hand, in an insulator string, if a clamp and a steel cap slip, it is likely to cause the clamp to cause damage to the zinc ring of the adjacent insulator, thereby increasing the cost of replacement. Summary of the invention

[0014] Wherein, the force-bearing part is used to make the connecting piece move toward the direction approaching the steel cap under the action of external force, so that one end of the connecting piece drives the first convex part and the second convex part to rotate synchronously, so that the clamping part rotates toward the direction approaching the steel cap until it abuts and locks the steel cap, and the second convex part abuts and limits the positioning convex body, and the elastic reset part is in a compressed state at this time; and when the external force acting on the force-bearing part is released, the elastic reset part elastically resets and drives the cam body to rotate and reset, so that the first convex part and the second convex part rotate in the direction away from the steel cap, so that the clamping part releases the lock on the steel cap, and the second convex part is spaced apart from the positioning convex body.

[0015] In one of the embodiments, a connecting recess is provided at one end of the engaging member; the clamping portion is arranged at the end of the connecting recess; the force-bearing portion is used to be subjected to the external force so that the end of the connecting recess is protruded from the inner wall of the accommodating cavity, so that the clamping portion and the steel cap are abutted and locked; and when the external force acting on the force-bearing portion is released, the curved surface where the connecting recess is located can be coplanar with the curved surface where the inner wall of the accommodating cavity is located.

[0016] In one of the embodiments, the insulator disassembly and assembly auxiliary mechanism includes at least two of the engaging members.

[0017] Among them, the at least two engaging parts include a first engaging part and a second engaging part; the first engaging part and the second engaging part are symmetrically and movably arranged on the fixing component along the axial direction of the accommodating cavity.

Among them, the clamping of the steel cap by the engaging member is a friction fixing method, which is different from the fixation of the steel cap by the accommodating cavity. The friction fixing area of ​​the steel cap by the clamping part is smaller, so that the friction force is more concentrated, and the steel cap can be effectively fixed to achieve anti-slip. Furthermore, the movement of the engaging member can reduce and change the installation matching size of the accommodating cavity to the steel cap. Even if it falls, the steel cap in a larger position can be clamped and limited by the engaging member, or slowed down to stop by greater friction to avoid further falling of the steel cap, thereby effectively avoiding the impact on other parts of the insulator and other insulators, effectively reducing the number of insulator replacements and reducing maintenance costs.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0041] Refer to Figure 1, which shows a structural schematic diagram of an insulator disassembly and assembly device 10 in an embodiment of the present application. The insulator disassembly and assembly device 10 provided in an embodiment of the present application includes an insulator disassembly and assembly auxiliary mechanism 100, a drive motor 200 and a transmission assembly 300.

[0042] Specifically, see Figures 2 to Figure 3 The insulator disassembly and assembly auxiliary mechanism 100 includes a fixing assembly 110 and a clamping member 120. The inner side wall of the accommodating cavity 111 is surrounded to form the accommodating cavity 111, and the accommodating cavity 111 is used to accommodate the steel cap 410 of the insulator 400. In one embodiment, the inner side wall of the accommodating cavity 111 can fit tightly with the steel cap 410, which is conducive to reducing the gap between the steel cap 410 and the accommodating cavity 111, improving the supporting capacity of the accommodating cavity 111 for the steel cap 410, and avoiding collision damage.

[0043] The engaging member 120 can be rotatably arranged on the fixing assembly 110. A force-bearing portion 121 is provided at one end of the engaging member 120, and a clamping portion 122 is provided at the other end. The engaging member 120 is provided with a fixing hole 1201, and the fixing hole 1201 is arranged near the force-bearing portion 121 relative to the middle of the engaging member 120. It should be noted that the fixing hole 1201 can be arranged adjacent to the force-bearing portion 121, or the position where the fixing hole 1201 is arranged on the engaging member 120 is the force-bearing portion 121, and the design selection can be made according to different usage requirements.

[0044] The driving assembly is installed and matched with the fixing hole 1201, so that the transmission assembly 300 is fixedly matched with the insulator disassembly and assembly auxiliary mechanism 100, so that the force-bearing part 121 switches between a force-bearing state and a non-force-bearing state.

[0045] It should be noted that, in an embodiment in which the insulator disassembly and assembly device 10 includes a drive motor 200 and a transmission assembly 300, the drive motor 200 can always act on the force-bearing part 121 through the transmission assembly 300, and the timing of acting on the force-bearing part 121 can also be selected according to needs, as long as the drive motor 200 can drive the locking member 120 to rotate relative to the fixed assembly 110 through the transmission assembly 300 to achieve the clamping part 122 locking the steel cap 410 located in the accommodating cavity 111 or releasing the resistance lock on the steel cap 410.

[0046] For ease of understanding, the working principle of the insulator disassembling and assembling device 10 is explained below in conjunction with the forward and reverse rotation of the driving motor 200.

[0047] If the driving motor 200 rotates forward, the transmission assembly 300 drives the engaging member 120 to rotate relative to the fixing assembly 110, so that the clamping portion 122 locks the steel cap 410 located in the accommodating cavity 111. Then, when the driving motor 200 rotates reversely, the transmission assembly 300 drives the engaging member 120 to rotate in the opposite direction relative to the fixing assembly 110, so that the clamping portion 122 releases the lock on the steel cap 410, and the steel cap 410 can slide relative to the accommodating cavity 111.

[0048] In the engaging member 120, the force-bearing portion 121 causes the clamping portion 122 to abut and lock the steel cap 410 located in the accommodating cavity 111 under the action of an external force, and when the external force acting on the force-bearing portion 121 is released, the clamping portion 122 releases the abutment and locking of the steel cap 410. Therefore, when the driving motor 200 releases the force acting on the transmission assembly 300 and the engaging member 120, it means that the external force acting on the force-bearing portion 121 is released.

[0049] Based on this, the force-bearing part 121 can be switched between a force-bearing state under the action of an external force and a non-force-bearing state in which the force-bearing part 121 releases the force by adjusting the working state of the driving component or the matching state of the transmission component 300 and the engaging member 120. For example, in some embodiments, the force-bearing state refers to the state of the force-bearing part 121 under the cooperation of the fixing hole 1201 and the transmission component 300, that is, when the transmission component 300 exerts a force on the engaging member 120, the external force brought by the transmission component 300 to the force-bearing part 121 can make the clamping part 122 move in the direction close to the steel cap 410, and then the clamping part 122 resists and locks the steel cap 410 to fix the steel cap 410. An example usage scenario is as follows: the transmission component 300 drives the auxiliary mechanism of the insulator 400 to move vertically downward, and at this time, the force-bearing part 121 can be subjected to a vertical downward force, so that the clamping part 122 is subjected to a horizontal component force, driving the clamping part 122 to move in the direction close to the steel cap 410.

[0050] Correspondingly, the non-stressed state refers to the state in which the cooperation between the transmission component 300 and the fixing hole 1201 is released, that is, when the transmission component 300 does not generate the specific external force on the engaging part 120, the effect of the external force on the force-bearing part 121 (that is, the force applied to the engaging part 120 by the transmission component 300 in the stress state) disappears. At this time, the force-bearing part 121 loses the external force, so that the clamping part 122 moves away from the steel cap 410, and then the clamping part 122 releases the resistance to the steel cap 410 to complete the unlocking.

[0051] In this way, through the active cooperation between the clamping member 120 and the fixing assembly 110, the clamping member 120 can be used to hold the steel cap 410 to achieve friction locking between the two. Different from the fixing of the steel cap 410 by the accommodating chamber 111, the friction fixing area of ​​the clamping member 120 is smaller, so that the friction force is more concentrated, and the steel cap 410 can be effectively fixed to avoid anti-slip. Furthermore, the activity of the clamping member 120 can reduce the size of part of the accommodating chamber 111. Even if it falls, the clamping member 120 can be used to clamp and fix the larger position of the steel cap 410, or slow down to stop by friction to prevent the steel cap 410 from falling further, thereby effectively avoiding the impact on other parts of the insulator 400 and other insulators 400, effectively reducing the number of replacements of the insulator 400 and reducing maintenance costs.

[0052] In addition, in an embodiment in which the insulator disassembly and assembly device 10 includes a drive motor 200 and a transmission assembly 300, the rotation state of the locking member 120 can be controlled by utilizing the presence or absence of the driving force of the drive motor 200 on the transmission assembly 300, so as to realize the switching of clamping and locking or releasing and unlocking the steel cap 410. There is no need to additionally set up fixing components such as screws that need to be manually disassembled to enhance the clamping effect, thereby reducing the setting of fixing components. At the same time, there is no need to manually disassemble the fixing components, thereby facilitating the disassembly and assembly operation.

[0053] It should be noted that, when the clamping portion 122 releases the support to the steel cap 410, the clamping portion 122 can be recessed or coplanar with the inner wall of the accommodating cavity 111. In addition, the transmission assembly 300 and the drive motor 200 can be matched in different ways, such as the matching of the flexible member and the winding machine, the drive of the screw rod and the motor, etc., which are not limited here.

[0054] In one embodiment, the transmission assembly 300 includes a driving screw. One end of the driving screw is transmission-connected to the driving motor 200, and the other end is fixedly connected to the fixing hole 1201. The driving motor 200 drives the driving screw and the engaging member 120 to move synchronously. In this way, the transmission accuracy is improved through the transmission cooperation between the driving screw and the driving motor 200, and the transmission speed is faster.

[0055] In one example, the other end of the driving screw is fixedly connected to the fixing hole 1201, which can be achieved by a fixing pin. Specifically, the driving screw is fixedly connected to the fixing hole 1201 by a fixing pin, so that the fixing pin can be used to increase the size of the fit, facilitate installation, and help improve installation efficiency.

[0056] It should be noted that the rotational cooperation between the engaging member 120 and the fixing assembly 110 may be achieved through a rotating shaft or through a stud or the like.

[0057] In some embodiments, see Figures 4 to 5 , the engaging member 120 is provided with a first mounting hole 123. The fixing assembly 110 is provided with a first matching hole 112 which is in communication with the first mounting hole 123. The insulator disassembly and assembly auxiliary mechanism 100 further includes a first fastener 130. The first fastener 130 is inserted and fixed in the first mounting hole 123 and the first matching hole 112, so that the engaging member 120 can be rotatably matched with the fixing assembly 110 through the first fastener 130, and the depth direction Y of the first mounting hole 123 is perpendicular to the axial direction X of the accommodating cavity 111.

[0058] For the sake of convenience, the principle of the insulator disassembly and assembly device 10 will be described below in conjunction with the driving motor 200 to drive the transmission assembly 300 and the engaging member 120 in forward and reverse rotations.

[0059] The cooperation principle of the force-bearing portion 121 and the clamping portion 122 can refer to the lever principle. Figure 3 As shown, assuming that the driving motor 200 rotates forward, the transmission assembly 300 can give the force-bearing part 121 a vertical downward force along the axial direction X. At this time, the force-bearing part 121 is in a force state under the action of a vertical downward external force, and then the clamping part 122 has a vertical upward motion vector along the axial direction X, so that the clamping part 122 rotates in the direction close to the steel cap 410, and gradually protrudes from the inner wall of the accommodating cavity 111, so that the clamping part 122 can abut against the steel cap 410 to fix the steel cap 410.

[0060] Correspondingly, when the driving motor 200 reverses, the transmission assembly 300 drives the engaging member 120 to rotate in the opposite direction relative to the fixing assembly 110. At this time, the force-bearing portion 121 is in a non-stressed state in which the vertically downward external force is released, and the steering transmission assembly 300 gives the force-bearing portion 121 a vertically upward force along the axial direction X, and then the clamping portion 122 has a vertically downward motion vector along the axial direction X, so that the clamping portion 122 rotates in the direction away from the steel cap 410 and gradually retracts to the inner side wall of the accommodating chamber 111, so that the clamping portion 122 can release the resistance to the steel cap 410, thereby facilitating the disassembly of the steel cap 410 relative to the accommodating chamber 111.

[0061] It can be understood that in this embodiment, the first fastener 130 has at least two functions. On the one hand, the first fastener 130 can serve as the rotating shaft of the engaging member 120, so that the engaging member 120 can rotate relative to the first fastener 130, thereby switching the clamping portion 122 toward or away from the steel cap 410 to achieve clamping or separation of the steel cap 410. On the other hand, the first fastener 130 is fixedly matched with the first mounting hole 123 and the first matching hole 112, which can achieve a fixed connection between the engaging member 120 and the clamping assembly, without the introduction of too many fixing elements, which is conducive to simplifying the structure and improving the connection strength between the engaging member 120 and the clamping assembly.

[0062] Specifically, in a specific embodiment, the first fastener 130 is a bolt, and the fixing assembly 110 is provided with an internal threaded hole arranged around the first matching hole 112. The bolt passes through the first matching hole 112 and the first mounting hole 123. The external thread of the bolt is threadedly matched with the second internal threaded hole, so that the engaging member 120 is fixedly connected to the fixing assembly 110. In this way, the fixing method of the threaded connection is convenient for disassembly and assembly, and has a good fixing effect, which is conducive to improving the connection strength between the engaging member 120 and the fixing assembly 110.

[0063] In another specific embodiment, see Figure 5 As shown, the first fastener 130 is a bolt, and the insulator disassembly and assembly auxiliary mechanism 100 also includes a nut matched with the bolt. The bolt passes through the first mounting hole 123 and the first matching hole 112 and is threadedly matched with the nut to fix the engaging member 120 and the fixing assembly 110. In this way, the engaging member 120 and the fixing assembly 110 are connected by directly threading the bolt and the nut, so that the first matching hole 112 does not need to be threaded, and the matching bolt and nut can be directly used, which reduces the processing steps and is conducive to improving the processing efficiency.

[0064] In conjunction with any of the above embodiments of the fixing assembly 110, refer to Figure 6 The fixing assembly 110 includes a first fixing member 114 and a second fixing member 115. The first fixing member 114 and the second fixing member 115 are fixedly connected, so that the first fixing member 114 and the second fixing member 115 surround and form a receiving cavity 111.

[0065] Further, in one embodiment, Figure 4As shown, the fixing assembly 110 is further provided with a mounting groove 113 communicating with the accommodating cavity 111. The engaging member 120 is inserted into the mounting groove 113. That is, the engaging member 120 is embedded in the mounting groove 113, and the engaging member 120 can rotate within a small range relative to the mounting groove 113 in the mounting groove 113, so that the engaging member 120 and the fixing assembly 110 can be rotatably matched. Among them, the installation groove 113 can be set on the first fixing member 114, can also be set on the second fixing member 115, or can be set between the two.

[0066] In this way, the design of the mounting groove 113 realizes the accommodation of the engaging member 120, making the disassembly and assembly auxiliary mechanism more beautiful as a whole. Further, the size design of the mounting groove 113 can be used to realize the small-range rotation of the engaging member 120, that is, the side wall of the mounting groove 113 can be used as the rotation fulcrum of the engaging member 120. The specific understanding can refer to the lever matching principle between the force-bearing part 121 and the clamping part 122 in the above embodiment, so that the rotation switching work in the direction of approaching or moving away from the steel cap 410 can be completed, and the structure is simple and the design is convenient.

[0067] In addition, in one example, the first fixing member 114 is provided with a mounting groove 113. Providing the mounting groove 113 on a single part does not require processing of two parts, reduces the occurrence of processing errors when the two parts are processed and matched, and improves the matching accuracy between the engaging member 120 and the mounting groove 113.

[0068] In combination with any of the above embodiments of the engaging member 120, refer to Figures 7 to 8 , the engaging member 120 is provided with a first surface 124 and a second surface 125 which are arranged opposite to each other along the depth direction Y. At least one of the first surface 124 and the second surface 125 is provided with a first matching structure 1202 (that is, the first matching structure 1202 can be installed to the first surface 124, the second surface 125 or both). The first matching structure 1202 is provided with a first end 1202a which is arranged close to the clamping portion 122 and a second end 1202b which is arranged close to the force-bearing portion 121. Among them, the first mounting hole 123 is arranged close to the clamping portion 122 relative to the middle part of the engaging member 120. Along the depth direction Y, the cross-sectional area S of the surface A where the first end 1202a is located is A Greater than the cross-sectional area S of the surface B where the second end 1202b is located B , so that the cross-sectional area of ​​the plane where the clamping portion 122 is located is larger than the cross-sectional area of ​​the plane where the force-bearing portion 121 is located, and then the engaging member 120 at least partially forms a wedge-like structure or a step-like structure.

[0069] It is understandable that a wedge-like structure or a step-like structure is formed on the engaging member 120, so that the axes of the clamping portion 122 and the force-bearing portion 121 are not consistent, and then there is an eccentric effect between the clamping portion 122 and the force-bearing portion 121, which can change the direction of the force (such as converting the vertical downward driving force received by the force-bearing portion 121 into a horizontal component force that drives the clamping portion 122 to move along the axial direction X, so that the clamping portion 122 rotates in the direction close to the steel cap 410). Further, the cross-sectional area S A Greater than the cross-sectional area S B , the engaging member 120 can form a labor-saving lever, that is, the torques of the force-bearing portion 121 and the clamping portion 122 are different, so that even when the force-bearing portion 121 takes a smaller force, it can still generate an increased clamping force on the clamping portion 122, which is conducive to labor saving.

[0070] In addition, in some embodiments, the engaging member 120 can be slidably matched with the mounting groove 113 in the above-mentioned embodiment to realize the limited sliding of the engaging member 120, improve the motion limit accuracy of the engaging member 120 and the mounting groove 113, and thus ensure the clamping accuracy of the engaging member 120 on the steel cap 410.

[0071] In one example, see Figure 8 , the first matching structure 1202 is installed to the first surface 124 and the second surface 125. In this way, when the force-bearing portion 121 is in a force-bearing state, the eccentric direction of the clamping member 120 is relatively concentrated, so that the clamping member 120 can move toward the direction close to the steel cap 410 and clamp with the steel cap 410, without the front and back shaking caused by the asymmetric arrangement of the first surface 124 and the second surface 125, avoiding the steel cap 410 from slipping, and improving the clamping effect of the clamping member 120 on the steel cap 410.

[0072] In one embodiment, Figures 7 to 8 , the first matching structure 1202 is a wedge-shaped structure. Specifically, the first matching structure 1202 is a ramp-like structure. Among them, the ramp-like structure can be an inclined plane structure or an inclined concave structure, and the inclined structure is gradually gathered toward the second end 1202b in the direction from the first end 1202a to the second end 1202b. In this way, through the setting of the ramp-like structure, the first matching structure 1202 is a wedge-shaped structure. When the force-bearing part 121 is subjected to force, it can have a good self-locking ability based on the wedge-shaped structure, so that the clamping part 122 has a good clamping and locking effect on the steel cap 410. Furthermore, the setting of the gradually closing width of the wedge-shaped structure is conducive to uniform clamping force on the steel cap 410. In addition, the design of the wedge-shaped structure is relatively simple, which is convenient for processing and helps to reduce processing costs.

[0073] In one embodiment, the clamping portion 122 can be formed integrally with the wedge structure. Specifically, the engaging member 120 is a wedge-shaped clamping member. The clamping portion 122 is one end of the wedge-shaped clamping member. The wedge-shaped clamping member is movably matched with the mounting groove 113 (equivalent to the wedge-shaped groove). When the force-bearing portion 121 is in a force-bearing state, the end of one side of the wedge-shaped clamping member (i.e., the clamping portion 122) rotates in a direction close to the steel cap 410 to achieve the clamping and locking of the steel cap 410 by the wedge-shaped clamping member. In this way, by integrating the arrangement on the wedge-shaped clamping member, the processing steps can be reduced and simplified, which is conducive to improving the processing efficiency.

[0074] In addition, in one embodiment, Figure 8 , the shape of the clamping portion 122 can also be adapted to the inner side wall of the accommodating cavity 111. Specifically, in one example, a connecting recess 1203 is provided at one end of the wedge-shaped clamp, and the clamping portion 122 is arranged at the end of the connecting recess 1203. That is, the steel cap 410 is clamped by the end of one side of the wedge-shaped clamp. Specifically, its working principle is as follows: when the force-bearing portion 121 is in a non-stressed state, the connecting recess 1203 is relative to the accommodating cavity 111, and the curved surface where the connecting recess 1203 is located is coplanar with the curved surface where the inner side wall of the accommodating cavity 111 is located. When the force-bearing portion 121 is in a stressed state, the end of the connecting recess 1203 is protrudingly arranged on the inner side wall of the accommodating cavity 111, and the clamping portion 122 is pressed and locked with the steel cap 410. That is, when the force-bearing portion 121 is in a non-stressed state, the clamping portion 122 and the inner side wall of the accommodating cavity 111 are located on the same curved surface. In this way, the insulator disassembly and assembly auxiliary mechanism 100 can be made more beautiful as a whole.

[0075] In another embodiment, see Figures 9 and 10 The engaging member 120 may also be in the form of a cam assembly. Specifically, the engaging member 120 further includes a cam body 126, an elastic reset member, and a connecting member 127. The cam body 126 is rotatably connected to the first fastener 130 via the elastic reset member. One end of the connecting member 127 is fixedly connected to the cam body 126, and the other end is fixedly connected to the force-bearing portion 121.

[0076] The cam body 126 is provided with a first convex portion 1261 and a second convex portion 1262. The clamping portion 122 is fixedly connected to the first convex portion 1261. The mounting groove 113 is provided with a positioning convex body that is limitedly matched with the second convex portion 1262.

[0077] For ease of understanding, the working principle of the insulator disassembling and assembling device 10 is described below in conjunction with the driving and stopping of the driving motor 200 , the transmission assembly 300 , and the engaging member 120 .

[0078] like Fig. 9As shown, it is assumed that the driving motor 200 drives the transmission assembly 300 and the engaging member 120 in a forward rotation, so that the transmission assembly 300 drives the engaging member 120 to rotate relative to the fixing assembly 110 (that is, the force-bearing portion 121 is in a force-bearing state under the action of an external force). Specifically, the force-bearing portion 121 drives one end of the connecting member 127 and the cam body 126 to rotate, so that the first convex portion 1261 and the clamping portion 122 rotate in a direction close to the steel cap 410, so that the second convex portion 1262 rotates to abut against the positioning convex body, so that the cam body 126 is fixed relative to the engaging member 120, and the elastic reset member is in a compressed state (the force-bearing portion 121 and the cam body 126 need to overcome the work of the elastic reset member), and the clamping portion 122 abuts and locks the steel cap 410. That is, the snap-fit ​​fixation between the second protrusion 1262 and the positioning protrusion limits the rotation angle of the cam body 126, so that when the force-bearing portion 121 moves in a directional direction, the rotation angle of the cam body 126 is fixed, driving the rotation angle of the clamping portion 122 to be fixed, so that the clamping portion 122 will not slip between the steel cap 410 due to the continuous rotation of the cam body 126, thereby improving the fixed clamping effect of the steel cap 410.

[0079] like Fig.10 As shown, assuming that the driving motor 200 stops driving the transmission assembly 300 and the engaging member 120 (i.e., the force-bearing portion 121 is in a non-stressed state in which the external force is released), the elastic reset member (such as a torsion spring or a tension spring, etc.) resets and drives the cam body 126 to reset and rotate, and the second protrusion 1262 is spaced apart from the positioning protrusion, thereby achieving the abutment unlocking between the second protrusion 1262 and the positioning protrusion, so that the first protrusion 1261 and the clamping portion 122 rotate in a direction away from the steel cap 410, and the engaging member 120 no longer has a resisting effect on the steel cap 410, thereby facilitating the disassembly of the auxiliary mechanism.

[0080] It should be noted that the number of the engaging members 120 in the above embodiment can be one, two, three, etc., and no excessive limitation is made here.

[0081] In combination with any of the above embodiments of the engaging member 120, Figure 3 The insulator disassembly and assembly auxiliary mechanism 100 includes at least two engaging members 120 .

[0082] In one example, the insulator disassembly and assembly auxiliary mechanism 100 includes two engaging members 120. The two engaging members 120 include a first engaging member 128 and a second engaging member 129. The first engaging member 128 and the second engaging member 129 are symmetrically and movably arranged on the fixing assembly 110 along the axial direction X. It can be understood that the first engaging member 128 and the second engaging member 129 are symmetrically arranged on the fixing assembly 110 along the axial direction X, so that the clamping and locking of the steel cap 410 by the clamping portion 122 also maintains a symmetrical state, which can increase the clamping area of ​​the steel cap 410 while improving the clamping stability of the steel cap 410, thereby achieving the locking stability of the clamping of the steel cap 410. Further, the fixing hole 1201 on the engaging member 120 is matched with the transmission assembly 300 in a one-to-one transmission manner, so that the insulator disassembly and assembly auxiliary mechanism 100 and the steel cap 410 can be symmetrically driven, and the motion stability of the steel cap 410 disassembly can be achieved. In addition, the number of the engaging members 120 will not be too large, so that the stability of the disassembly of the steel cap 410 can be ensured while the cost of installing the engaging members 120 will not be increased.

[0083] In another example, the insulator 400 disassembly auxiliary mechanism includes at least three engaging members 120. The at least three engaging members 120 include a first engaging member 128, a second engaging member 129, and a third engaging member. The first engaging member 128, the second engaging member 129, and the third engaging member are sequentially arranged on the fixing assembly 110 at intervals. In this way, when the clamping portions 122 on the first engaging member 128, the second engaging member 129, and the third engaging member are clamped and locked with the steel cap 410, a clamping and locking surface can be formed, which effectively improves the clamping and locking effect of the steel cap 410.

[0084] It should be noted that the fixing method of the first fixing member 114 and the second fixing member 115 in the above embodiment can be, but is not limited to, screw fixing, plug fixing, magnetic fixing, etc., and no excessive restrictions are made here.

[0085] In conjunction with any of the above embodiments of the fixing assembly 110, refer to Figures 11 to 12 , one of the first fixing member 114 and the second fixing member 115 is provided with a sliding portion, and the other is provided with a sliding matching portion 1151. The sliding portion and the sliding matching portion 1151 are plugged and matched so that the first fixing member 114 can be switched at least between the first position and the second position relative to the second fixing member 115. That is, the first fixing member 114 and the second fixing member 115 are fixedly connected by sliding matching. Specifically, when the first fixing member 114 is in the first position, the first fixing member 114 and the second fixing member 115 are fixedly connected to enclose and form the accommodating cavity 111. When the first fixing member 114 is in the second position, the first fixing member 114 can be slidably matched with the second fixing member 115. In this way, the sliding installation method is convenient to operate and is conducive to improving the installation efficiency.

[0086] Furthermore, in order to improve the fixing and matching effect of the first fixing member 114 and the second fixing member 115, in one embodiment, the fixing assembly 110 further includes a second fastener 116. The sliding portion is provided with a second mounting hole, the sliding matching portion 1151 is provided with a second matching hole, and the second fastener 116 is penetrated and fixed in the second mounting hole and the second matching hole, so that the first fixing member 114 is fixedly connected with the second fixing member 115. In this way, through the matching of the second fastener 116 with the second mounting hole and the second matching hole, the connection strength of the first fixing member 114 and the second fixing member 115 is strengthened, thereby improving the connection strength between the fixing assembly 110 and the engaging member 120, so that the clamping and locking effect of the engaging member 120 and the steel cap 410 is better.

[0087] In addition, in order to improve the installation and fixing efficiency of the first fixing member 114 and the second fixing member 115, in one embodiment, the first fixing member 114 is provided with a sliding portion, and the second fixing member 115 is provided with a sliding matching portion 1151. Fig.11 As shown, the first fixing member 114 includes a mounting body 1141 provided with a slide groove 1142 and a limiting boss 1143 protruding from the mounting body 1141. Fig.12 As shown, the sliding portion includes a slide groove 1142. The slide groove 1142 is arranged adjacent to the limiting boss 1143. The sliding matching portion 1151 includes a sliding body 1151a and a limiting flange 1151b that are limited and slidably matched with the slide groove 1142. Along the sliding matching direction between the slide groove 1142 and the sliding body 1151a, the sliding body 1151a is provided with a third end and a fourth end at intervals. The third end is fixedly connected to the limiting flange 1151b, and the fourth end is provided with a second matching hole.

[0088] For ease of understanding, the usage scenario is described below in conjunction with the sliding cooperation between the sliding groove 1142 and the sliding body 1151a.

[0089] See you later Figure 4As shown, assuming that the sliding matching direction of the slide groove 1142 and the sliding body 1151a is the first direction, when the first fixing member 114 is in the first position, the limiting flange 1151b and the limiting boss 1143 are in contact and limited matching, and at this time, the second fastener 116 can be inserted and fixed between the second mounting hole and the second matching hole, so that the first fixing member 114 and the second fixing member 115 are locked. By using the second fastener 116 and the matching of the limiting flange 1151b and the limiting boss 1143, the first fixing member 114 and the second fixing member 115 can be locked in the first direction (such as preventing left and right reset sliding). At the same time, the side wall of the slide groove 1142 can be used to make the sliding body 1151a and the slide groove 1142 match to achieve the locking of the second direction perpendicular to the first direction (such as preventing up and down movement). In this way, the movement locking of the first fixing member 114 and the second fixing member 115 on the plane is formed, and the fixing effect of the first fixing member 114 and the second fixing member 115 is improved.

[0090] If the second fastener 116 is unlocked and the first fixing member 114 is slid to the second position, the limiting flange 1151b is spaced apart from the limiting boss 1143. At this time, the first fixing member 114 can slide relative to the second fixing member 115 to achieve separation of the first fixing member 114 and the second fixing member 115.
