Description

Technical Field

[0001] The present application relates to the technical field of clamping devices, and in particular to a clamping device for a spring bayonet. Background Art

[0002] In the power system, spring bayonet, as a key connection and fixing element, is of great significance for ensuring the stable operation of power equipment. Among them, spring bayonet is widely used in hexagonal head bolts with pin holes (i.e., pin bolts) due to its unique structural characteristics and excellent limiting function; this spring bayonet can effectively limit the range of motion of the connection parts through its elastic effect, prevent the bolts from falling off, and thus ensure the safe operation of the power grid. However, in practical applications, the removal and placement of spring bayonet faces many challenges; especially in transmission lines, due to the large number of spring bayonet, for example, in the multiple conductor tension strings of voltage levels such as 500kN and 1000kN, the number of spring bayonet can often reach more than dozens. The traditional method of taking and placing spring bayonet mainly relies on manual operations such as knocking. The knocking operation will not only cause certain damage to the spring bayonet and the connection parts, affecting their service life and reliability; but also requires the staff to have a high level of operating skills. If the operation is improper, it may cause electric shock accidents, causing serious physical injuries to the operators, and even endangering their lives, and there are safety hazards.

[0003] In addition, with the continuous development of the power grid, the requirements for live working are getting higher and higher. The traditional pick-and-place method not only cannot meet the requirements of fast, efficient and safe operation, but also has a certain impact on the normal operation of the power grid. Therefore, in view of this, the inventor proposes a clamping device with a spring bayonet to solve the above technical problems. Summary of the invention

[0004] In view of this, the present application provides a clamping device for a spring bayonet, which is used to solve the technical problem that the traditional spring bayonet is difficult to pick up and put when working at high altitude. In order to achieve one or part or all of the above purposes or other purposes, the present application provides a clamping device for a spring bayonet, comprising a first guide rod and a second guide rod, wherein the first guide rod and the second guide rod are rotatably connected, and the central axis of the first guide rod and the central axis of the second guide rod are arranged at a preset angle;

[0005] A connecting member, wherein two ends of the connecting member are respectively connected to the first guide rod and the second guide rod, and the connecting member can slide on the first guide rod and the second guide rod at the same time, and the first guide rod, the second guide rod and the connecting member are enclosed together to form a triangular structure;

[0006] Wherein, a driving member is disposed on the first guide rod and a clamping member is disposed on the second guide rod; or,

[0007] A clamping member is provided on the first guide rod and a driving member is provided on the second guide rod;

[0008] The driving member can drive the clamping member to open or close through the connecting member.

[0009] According to the above technical solution, the clamping device of the spring latch cleverly utilizes the stability of the triangular structure and the flexibility of the sliding connection; when the device is in the initial state, the first guide rod and the second guide rod are connected to a preset angle through a rotatable connection to form a stable triangular frame, and the two ends of the connecting member are respectively connected to the first guide rod and the second guide rod for sliding connection, which means that the connecting member can slide freely along the two guide rods while maintaining the connection with both (the first guide rod and the second guide rod), thereby ensuring the stability and coordination of the entire structure. In terms of working principle, the driving member in the device is a key component, which is located on the first guide rod or the second guide rod and is responsible for providing power. When the driving member is activated, it moves along the guide rod and transmits power through the connecting member. After receiving the power, the connecting member slides along the first guide rod and the second guide rod, thereby changing its position relative to the two. This sliding movement then drives the clamping member set on the other guide rod to open or close. Specifically, if the driving member moves along the first guide rod, it will push or pull the clamping member on the second guide rod through the connecting member, causing it to open to clamp the spring pin or close to release the spring pin; vice versa, if the driving member is located on the second guide rod, it will affect the clamping member on the first guide rod through the connecting member. The design of the spring pin clamping device greatly improves the convenience and efficiency of operation, and the stability of the triangular structure ensures that the device is not easily deformed or damaged when clamping the spring pin. Secondly, the flexibility of the sliding connection allows the clamping member to open and close easily, thereby quickly and accurately clamping and releasing the spring pin. In addition, since the device is compact and easy to operate, it is very suitable for use at high altitudes, in narrow spaces or in complex environments.

[0010] Preferably, the connecting member comprises a first ring, a second ring and a connecting rod;

[0011] The first sleeve is sleeved on the first guide rod, and the first sleeve can slide along the length direction of the first guide rod;

[0012] The second sleeve is sleeved on the second guide rod, and the second sleeve can slide along the length direction of the second guide rod;

[0013] Two ends of the connecting rod are respectively connected to the first guide rod and the second guide rod.

[0014] According to the above technical solution, the working principle of the spring pin clamping device is based on its unique structural design. First, the first ring and the second ring are respectively mounted on the first guide rod and the second guide rod, and both can slide freely along the length direction of their respective guide rods; the two ends of the connecting rod are respectively connected to the first ring and the second ring, thereby indirectly connected to the first guide rod and the second guide rod; such a design enables the connecting piece to slide synchronously on the first guide rod and the second guide rod while maintaining the stability of the triangular structure formed between the three. In the process of clamping the spring pin, an external driving force (such as manual rotation, hydraulic push, etc.) acts on an operating component connected to the first guide rod or the second guide rod, so that the relative position of the first guide rod or the second guide rod changes. Since the connecting piece is connected to the two guide rods (the first guide rod and the second guide rod) at the same time and can slide thereon, as the position of the guide rods changes, the connecting piece will also slide on the two guide rods accordingly, thereby changing the shape and size of the triangle enclosed by the first guide rod, the second guide rod and the connecting piece. This change directly drives the opening or closing of the clamping jaws connected to the connecting piece. When the shape of the triangular frame changes, the distance between the clamping jaws changes accordingly, thereby achieving the clamping or release of the spring pin.

[0015] On the one hand, the stability of the triangular structure ensures the stability of the device during the clamping process; on the other hand, the flexibility of the sliding connection enables the fast and accurate clamping and release of the spring bayonet, greatly improving the work efficiency. In addition, the design of the device is also universal and can be applied to the clamping needs of spring bayonet pins of different sizes and shapes.

[0016] Preferably, the clamping member comprises a first clamping jaw and a second clamping jaw, the first clamping jaw and the second clamping jaw are arranged in an "X" shape, and the first clamping jaw and the second clamping jaw are hinged to each other;

[0017] The top end of the first clamping jaw is fixedly connected to the first guide rod, and the top end of the second clamping jaw is fixedly connected to the first sleeve ring.

[0018] According to the above technical solution, the working principle of the spring pin clamping device mainly relies on its unique driving member design and the stability of the triangular structure. The driving member consists of a first clamping jaw and a second clamping jaw, which are arranged in an "X" shape and hinged to each other to form a structure that can be flexibly opened and closed.

[0019] In the initial state, the top end of the first jaw is fixedly connected to the first guide rod (or related components), and the top end of the second jaw is fixedly connected to the second ring. This design enables the first jaw to move when the first ring moves, and then transmits force through the hinge point to make the second jaw produce corresponding movement.

[0020] When the spring pin needs to be clamped, the first guide rod or the component connected thereto can be driven to move by external force (such as manual operation, electric drive, etc.); since the first clamping jaw and the second clamping jaw are arranged in an "X" shape, their sliding will cause the angle between the two to change, thereby realizing the opening or closing of the clamping piece and the placement or clamping of the spring pin.

[0021] Preferably, a first elastic member is sleeved on the first guide rod, the first elastic member is located between the first clamping jaw and the second clamping jaw, and the first elastic member has a tendency to drive the driving member to transform from a closed state to an open state.

[0022] Preferably, it further comprises a connecting head, which is arranged at the intersection of the first guide rod and the second guide rod and is used to connect the first guide rod and the second guide rod;

[0023] The first guide rod is rotatably or fixedly connected to the connecting head;

[0024] The second guide rod is fixedly or rotatably connected to the connecting head.

[0025] According to the above technical solution, the working principle and effect of the spring bayonet clamping device are further optimized and improved. The core lies in the introduction of the connector, which is cleverly arranged at the intersection of the first guide rod and the second guide rod, playing a key connection and support role.

[0026] When working, first, the connector acts as the hub of the entire device, allowing the first guide rod and the second guide rod to rotate relative to each other or remain fixed within a certain range, which enables the device to adapt to different working angles and requirements; the driving member, a component that can rotate or move, is installed on the first guide rod. When the driving member is subjected to external force (such as manual rotation or electric drive), it will move along the first guide rod, and this movement is transmitted to the clamping member on the second guide rod through the connecting member; the clamping member is a clamping claw that can be relatively opened or closed, and is designed to clamp or release the spring latch. As the driving member moves, the connecting member will push or pull the clamping member to open or close it. Specifically, when the driving member moves forward, the connecting member will push the clamping member to close and clamp the spring latch; when the driving member moves backward, the connecting member will pull the clamping member to open and release the spring latch. This design not only simplifies the operation process and improves the work efficiency, but also enhances the stability and reliability of the device. The introduction of the connector makes the device more flexible and adaptable to more operating scenarios. At the same time, the stability of the triangular structure ensures that the device is not easily deformed or damaged when subjected to force, thereby extending its service life. In general, the spring bayonet clamping device provides strong support for the maintenance and overhaul of power systems with its unique working principle and remarkable effect.

[0027] Preferably, a fastener is provided on the connecting head, and the fastener is rotatably mounted on the connecting head, and the fastener fixes the first guide rod and the second guide rod through the connecting head.

[0028] According to the above technical solution, the spring bayonet clamping device adds a fastener design on the original basis, further improving its stability and practicality; in terms of working principle, when the device needs to clamp or release the spring bayonet, the angle between the first guide rod and the second guide rod is adjusted by adjusting the position of the fastener. The fastener is rotatably mounted on the connecting head, so that the operator can flexibly adjust the angle between the first guide rod and the second guide rod according to actual needs to adapt to different working environments and working angles; after adjusting the angle, the fastener fixes the first guide rod and the second guide rod through the connecting head to ensure that the device will not shake or deform due to external forces during use. Under the action of the driving member, the connecting member begins to slide on the first guide rod and the second guide rod. This sliding process drives the opening or closing of the clamping member, thereby achieving the clamping or release of the spring bayonet. The clamping piece is designed with an X-shaped structure. When the connecting piece slides upward, the two jaws of the clamping piece gradually close under the action of the spring and tightly clamp the spring pin; conversely, when the connecting piece slides downward, the two jaws of the clamping piece gradually open and release the spring pin. By adjusting the position and angle of the fastener, the operator can easily cope with various complex working environments and operation requirements, greatly improving work efficiency and operation quality.

[0029] Preferably, a second elastic member is sleeved on the second guide rod, and the second elastic member is arranged between the connecting head and the second ring. The second elastic member has a tendency to drive the second ring away from the connecting head.

[0030] According to the above technical solution, the second elastic member is cleverly arranged between the connector and the second sleeve ring. The second elastic sleeve is arranged on the second guide rod and has a certain elastic potential energy, and always maintains a tendency to push the second sleeve ring away from the connector. This design enables the clamping member to automatically remain in a relatively open state when the device is not subjected to external force, making it convenient for the operator to put the spring bayonet into the clamping position. When it is necessary to clamp the spring bayonet, the operator can push the connector to slide on the first guide rod and the second guide rod through the driving member. As the connector slides, the two clamping claws of the clamping member begin to gradually close and compress the second elastic member at the same time. In this process, the second elastic member stores a certain elastic potential energy, which provides power for the subsequent release action.

[0031] When the clamping member successfully clamps the spring latch, if it needs to be released, the operator only needs to stop applying force to the driving member, and the second elastic member will use its stored elastic potential energy to push the second ring and the connecting member along the second guide rod to move away from the connecting head. This movement process drives the clamping member to open, thereby smoothly releasing the spring latch.

[0032] This design not only improves the automation and operation convenience of the clamping device, but also makes the device more stable and reliable in the process of clamping and releasing the spring latch. In addition, the introduction of the second elastic member also enhances the adaptability and durability of the device, enabling it to better cope with various complex working environments and operating requirements.

[0033] Preferably, the driving member is a screw block, the second guide rod is a screw rod, and the screw block is sleeved on the screw rod;

[0034] The screw block is provided with an internal thread, the outer periphery of the screw rod is provided with an external thread, and the internal thread is matched with the external thread.

[0035] According to the above technical solution, the spring bayonet clamping device further improves its operation convenience and clamping accuracy by adopting a screw block as a driving member and designing the second guide rod as a screw. In terms of working principle, the screw block is sleeved on the screw and is adapted to the external thread of the screw through its internal thread, forming a thread transmission mechanism, so that the operator only needs to rotate the screw block, and the screw block moves up and down on the screw (i.e., the second guide rod), and the screw block pushes the position of the connecting member on the first guide rod and the second guide rod (screw) to change accordingly, thereby driving the clamping member to open or close. Specifically, when the operator rotates the screw block clockwise, the screw block will move upward along the external thread of the screw, drive the clamping member to close through the connecting member, and clamp the spring bayonet; conversely, when the operator rotates the screw block counterclockwise, the screw block will move downward along the external thread of the screw, drive the clamping member to open through the connecting member, and release the spring bayonet.

[0036] This threaded drive design not only makes the operation of the device simpler and more intuitive, but also greatly improves the accuracy and stability of clamping. Due to the characteristics of the threaded drive, the device can maintain a high clamping force and stability when clamping the spring bayonet, effectively avoiding shaking or falling off caused by external forces.

[0037] In addition, the design also makes the device highly adaptable and flexible. The operator can control the opening and closing degree of the clamping piece by adjusting the rotation angle and speed of the screw block according to actual needs, thereby achieving the clamping and release of spring bayonet pins of different sizes and shapes. In general, the spring bayonet pin clamping device provides strong support for the maintenance and overhaul of the power system with its unique working principle and remarkable effect.

[0038] Preferably, a mounting position is provided at one end of the screwing block away from the second guide rod;

[0039] The mounting position includes a threaded hole and / or a slot for connecting with the insulating operating rod.

[0040] According to the above technical solution, in terms of working principle, the design of the mounting position allows the operator to reliably connect the insulating operating rod with the screw block. The mounting position specifically includes multiple forms of threaded holes and / or card slots, which provides the operator with multiple connection options. If one end of the insulating operating rod is designed with an external thread, it can be threadedly connected to the threaded hole on the screw block; if one end of the insulating operating rod is designed with a buckle or other card connection structure, it can be carded with the card slot on the screw block. This design allows the operator to rotate the screw block through the insulating operating rod at a safe distance away from the live equipment, thereby realizing remote control of the spring bayonet clamping device. This not only greatly improves the safety of operation, but also enables the device to be used in a wider range of scenarios, such as live work and high-altitude work in power systems. In addition, the design of the mounting position also takes into account the convenience and stability of operation. Whether it is a threaded connection or a card connection, it can ensure that the connection between the insulating operating rod and the screw block is firm and reliable, avoiding operational errors or safety accidents caused by loose connections. In general, the spring pin clamping device achieves reliable connection and remote control with the insulating operating rod by opening a mounting position on its screw block, further improving the operational flexibility and wide application scenarios of the device, and bringing more convenience and safety guarantees to the maintenance and inspection of the power system.

[0041] On the other hand, the present invention also provides a method for using a clamping device for a spring bayonet, using the clamping device for the spring bayonet as described above, comprising the following steps:

[0042] S1: The first guide rod is connected to the second guide rod, and the central axes of the two are set at a preset angle; the first guide rod and / or the second guide rod can rotate, and the two ends of the connecting member are respectively connected to the first guide rod and the second guide rod, and can slide on the first guide rod and the second guide rod at the same time to form a triangular structure together;

[0043] S2: a clamping member is arranged on the first guide rod, and a driving member is arranged on the second guide rod; the clamping member includes a first clamping jaw and a second clamping jaw, which are arranged in an "X" shape and hinged to each other, so that the top end of the first clamping jaw is fixedly connected to the end of the first guide rod, and the top end of the second clamping jaw is connected to the second sleeve;

[0044] S3: a connecting head is arranged at the intersection of the first guide rod and the second guide rod to connect the two and enable the first guide rod and the second guide rod to rotate relative to the connecting head; a fastener is arranged on the connecting head to limit and fix the first guide rod and the second guide rod through the fastener;

[0045] S4: The driving member moves to drive the connecting member to slide on the first guide rod and the second guide rod, thereby driving the first clamping jaw and the second clamping jaw of the clamping member to open or close through the connection relationship between the connecting member and the second clamping jaw, thereby clamping or releasing the spring latch.

[0046] Implementing the embodiments of the present application will have the following beneficial effects:

[0047] 1. The present invention realizes the flexibility and adaptability of the clamping action by rotatably connecting the first guide rod and the second guide rod, and setting the central axis of the two at a preset angle. This design enables the device to operate effectively in narrow or complex spaces, and improves the accuracy and efficiency of clamping the spring bayonet. At the same time, the formation of the triangular structure enhances the stability and bearing capacity of the overall structure, ensuring the safety and reliability during the clamping process. Secondly, the connecting member can not only slide on the first guide rod and the second guide rod at the same time, but also serves as a bridge between the two, realizing effective linkage between the driving member and the clamping member. This design simplifies the transmission mechanism, so that the driving member can more efficiently drive the clamping member to open or close through the connecting member, thereby realizing rapid and stable clamping and release of the spring bayonet.

[0048] 2. The clamping device of the present invention realizes reliable connection and remote control with the insulating operating rod by opening a mounting position on its screw block. This design enables the device to be used in a wider range of scenarios, such as live operations in power systems and high-altitude operations, which not only improves the versatility and flexibility of the device, but also enables the device to meet the needs of different application scenarios.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] This embodiment provides a clamping device for a spring latch, such as Figures 1 to 3 As shown, it includes a first guide rod 1, a second guide rod 2 and a connecting member 3, the first guide rod 1 and the second guide rod 2 are rotatably connected, and the central axis of the first guide rod 1 and the central axis of the second guide rod 2 are set at a preset angle; the two ends of the connecting member 3 are respectively connected to the first guide rod 1 and the second guide rod 2, the connecting member 3 can slide on the first guide rod 1 and the second guide rod 2 at the same time, and the first guide rod 1, the second guide rod 2 and the connecting member 3 are together enclosed to form a triangular structure; wherein, the first guide rod 1 is provided with a driving member 4 and the second guide rod 2 is provided with a clamping member 5; or, the first guide rod 1 is provided with a clamping member 5 and the second guide rod 2 is provided with a driving member 4; the driving member 4 can drive the clamping member 5 to open or close through the connecting member 3.

[0058] In this embodiment and the following contents, it is explained that the first guide rod 1 is provided with a clamping member 5 and the second guide rod 2 is provided with a driving member 4 .

[0059] The spring pin 10 clamping device provided in this embodiment cleverly utilizes the stability of the triangular structure and the flexibility of the sliding connection; when the device is in the initial state, the first guide rod 1 is connected to the second guide rod 2 at a preset angle to form a stable triangular frame, and the two ends of the connecting member 3 are respectively slidingly connected to the first guide rod 1 and the second guide rod 2, which means that the connecting member 3 can slide freely along the two guide rods (the first guide rod 1 and the second guide rod 2) while maintaining connection with both of them, thereby ensuring the stability and coordination of the entire structure.

[0060] As a preferred implementation of this embodiment, Figure 2 As shown, the connecting member 3 includes a first ring 31, a second ring 32 and a connecting rod 33; the first ring 31 is sleeved on the first guide rod 1, and the first ring 31 can slide along the length direction of the first guide rod 1; the second ring 32 is sleeved on the second guide rod 2, and the second ring 32 can slide along the length direction of the second guide rod 2; the two ends of the connecting rod 33 are respectively connected to the first ring 31 and the second ring 32, specifically, the two ends of the connecting rod 33 are connected in the form of hinged connection with the first ring 31 and the second ring 32, so that the connecting member 3 can slide synchronously on the first guide rod 1 and the second guide rod 2, while maintaining the stability of the triangular structure formed between the three.

[0061] In a possible embodiment, the surfaces of the first guide rod 1 and the second guide rod 2 are both provided with guide grooves (not shown), and the first collar 31 and the second collar 32 of the connector 3 are respectively provided with guide protrusions (not shown) matching the guide grooves, and the guide protrusions can slide in the guide grooves. This embodiment achieves a more precise and stable sliding connection by providing guide grooves on the surfaces of the first guide rod 1 and the second guide rod 2, and providing guide protrusions matching the guide grooves inside the first collar 31 and the second collar 32 of the connector 3. The cooperation between the guide grooves and the guide protrusions prevents the connector 3 from deflecting or shaking during the sliding process, thereby enhancing the structural strength and stability of the entire device.

[0062] In the process of clamping the spring bayonet 10, as the driving member 4 moves, the connecting member 3 slides along the guide grooves on the surfaces of the first guide rod 1 and the second guide rod 2 through the guide protrusions inside it, further improving the accuracy and reliability of the opening or closing of the clamping member 5. In addition, the cooperation between the guide groove and the guide protrusion also enables the device to maintain good sliding performance and wear resistance to a certain extent during long-term use, thereby extending the service life of the device.

[0063] As a preferred implementation mode of this embodiment, the clamping member 5 includes a first clamping jaw 51 and a second clamping jaw 52, ​​the first clamping jaw 51 and the second clamping jaw 52 are arranged in an "X" shape, and the first clamping jaw 51 and the second clamping jaw 52 are hinged to each other; the top end of the first clamping jaw 51 is connected to the end of the first guide rod 1, and the top end of the second clamping jaw 52 is connected to the first ring 31. Such a design enables the clamping member 5 to move when the first ring 31 moves, and then the first clamping jaw 51 and the second clamping jaw 52 produce corresponding movements through the rotation of the hinge point.

[0064] When the spring pin 10 needs to be clamped, the driving member 4 can be moved by external action (such as manual operation, electric drive, etc.); since the first clamping jaw 51 and the second clamping jaw 52 are arranged in an "X" shape, their sliding will cause the angle between the first clamping jaw 51 and the second clamping jaw 52 to change, thereby realizing the opening or closing of the clamping member 5 and the placement or clamping of the spring pin 10.

[0065] Of course, it is understandable that in other embodiments, the clamping member 5 may also be other structures, as long as the clamping member 5 can clamp or release the spring latch 10 through the movement of the first ring 31 .

[0066] As a preferred implementation of this embodiment, a first elastic member 8 is sleeved on the first guide rod 1, and the first elastic member 8 is located between the first clamping jaw 51 and the second clamping jaw 52. The first elastic member 8 has a tendency to drive the driving member 4 to change from a closed state to an open state.

[0067] In this embodiment, the first elastic member 8 is provided so that when the device is not subjected to external force, the first jaw 51 and the second jaw 52 can be maintained in a relatively open state. When external force acts on the driving member 4, the elastic force of the first elastic member 8 can be overcome, so that the first jaw 51 and the second jaw 52 are gradually closed, thereby clamping the spring pin 10; when the external force disappears, the elastic force of the first elastic member 8 can drive the first jaw 51 and the second jaw 52 to automatically open, releasing the spring pin 10; such a design not only simplifies the operation process, but also improves the automation and practicality of the device; in this embodiment, the first elastic member 8 is concretized as a spring, and its two ends are fixedly connected to the first jaw 51 and the second jaw 52 respectively. This design further enhances the automation and ease of operation of the device.

[0068] In a possible implementation, the bottom of the first clamping jaw 51 and the inner side of the bottom of the second clamping jaw 52 (or the side close to each other) in the clamping member 5 are both provided with anti-slip teeth, which are used to increase the friction between the spring clamping pin 10 and prevent the spring clamping pin 10 from slipping during the clamping process, further improving the stability and reliability of the device in the process of clamping the spring clamping pin 10, so that the spring clamping pin 10 is more secure when clamped and is not easy to slip. This design is particularly suitable for the clamping operation of the spring clamping pin 10 at high altitude, in a small space or in a complex environment, and can effectively avoid operation failure or safety accidents caused by the spring clamping pin 10 slipping.

[0069] At the same time, the material and shape of the anti-slip teeth can also be selected and adjusted according to actual needs to meet the needs of different spring bayonet pins 10 types and working environments.

[0070] As a preferred implementation manner of this embodiment, it also includes a connecting head 6, which is arranged at the intersection position of the first guide rod 1 and the second guide rod 2, and is used to connect the first guide rod 1 and the second guide rod 2; the first guide rod 1 is rotatably or fixedly connected to the connecting head 6; the second guide rod 2 is fixedly or rotatably connected to the connecting head 67, and the connecting head 6 plays a role of connection and support limitation.

[0071] As an exemplary embodiment, this embodiment adopts a method in which the connecting head 6 is fixedly connected to the second guide rod 2, and the connecting head 6 is rotatably connected to the first guide rod 1. At the same time, when the connecting head 6 connects the first guide rod 1 and the second guide rod 2, the axis of the first guide rod 1 is perpendicular to the axis of the second guide rod 2.

[0072] When performing the clamping operation, firstly, the connector 6 serves as the connecting hub of the entire device, allowing the first guide rod 1 and the second guide rod 2 to rotate relative to each other along their own axes within a certain range, which enables the device to adapt to the clamping requirements of different working angles.

[0073] As a preferred implementation of this embodiment, a fastener 7 is provided on the connector 6, and the fastener 7 is rotatably mounted on the connector 6. The fastener 7 limits and fixes the first guide rod 1 and the second guide rod 2 through the connector 6. The spring bayonet clamping device provided in this embodiment adds the design of the fastener 7 on the original basis, further improving its stability and practicality. When the device needs to clamp or release the spring bayonet 10, first adjust the angle between the first guide rod 1 and the second guide rod 2, and after adjusting to a suitable position, limit and fix the first guide rod 1 and the second guide rod 2 by twisting the fastener 7. In this embodiment, the fastener 7 is rotatably mounted on the connector 6, so that the operator can flexibly adjust the rotation of the first guide rod 1 according to actual needs, which is convenient for use.

[0074] As a preferred implementation of this embodiment, the driving member 4 is a screw block, the second guide rod 2 is a screw rod, and the screw block is sleeved on the screw rod; the screw block is provided with an internal thread, and the outer periphery of the screw rod is provided with an external thread, and the internal thread and the external thread are adapted. According to the above technical scheme, the spring bayonet 10 clamping device further improves its operation convenience and clamping accuracy by adopting a screw block as the driving member 4 and designing the second guide rod 2 as a screw rod. In terms of working principle, the screw block is sleeved on the screw rod, and its internal thread is adapted to the external thread of the screw rod, forming a thread transmission mechanism, so that the operator only needs to rotate the screw block, and the screw block moves up and down on the screw rod (i.e., the second guide rod 2), and the screw block pushes the connecting member 3 on the first guide rod 1 and the second guide rod 2 (screw rod) to change its position accordingly, thereby driving the clamping member 5 to open or close. Specifically, when the operator rotates the screw block clockwise, the screw block moves upward along the external thread of the screw rod, and drives the first ring 31 to approach the clamping member 5 through the connecting member 3, and the distance between the second clamping jaw 52 on the clamping member 5 and the upper end of the first clamping jaw 51 changes, thereby driving the clamping member 5 to close and clamp the spring bayonet 10; conversely, when the operator rotates the screw block counterclockwise, the screw block moves downward along the external thread of the screw rod, and drives the clamping member 5 to open through the connecting member 3, releasing the spring bayonet 10; this threaded transmission design not only makes the operation of the device simpler and more intuitive, but also greatly improves the accuracy and stability of clamping. Due to the characteristics of the threaded transmission, the device can maintain a high clamping force and stability when clamping the spring bayonet 10, effectively avoiding shaking or falling off due to external forces.

[0075] Of course, it is understandable that the driving member 4 includes but is not limited to the screw block in the above embodiment, and the driving member 4 may also be a telescopic cylinder, a pneumatic cylinder, etc., as long as it can push the second ring 32 to slide along the axial direction of the second guide rod 2. Based on the technical solution in this embodiment, the operator can control the opening and closing degree of the clamping member 5 by adjusting the rotation angle and speed of the screw block according to actual needs, thereby clamping and releasing the spring bayonet 10 of different sizes and shapes; in general, the spring bayonet 10 clamping device provides strong support for the maintenance and repair of the power system with its unique working principle and remarkable effect.

[0076] As a preferred implementation of this embodiment, a mounting position is provided at one end of the screwing block away from the second guide rod 2; the mounting position includes a threaded hole 41 and / or a slot 42 for connecting with the insulating operating rod.

[0077] In this embodiment, the mounting position adopts the form of a combination of a threaded hole 41 and a slot 42; of course, it is understandable that the mounting position can also be in the form of only a threaded hole 41 or only a slot 42. According to the above technical solution, the design of the mounting position allows the operator to reliably connect the insulating operating rod (not shown) with the screw block. The mounting position specifically includes multiple forms of threaded holes 41 and / or slots 42, which provides the operator with a variety of connection options. If one end of the insulating operating rod is designed with an external thread, it can be threadedly connected to the threaded hole 41 on the screw block; if one end of the insulating operating rod is designed with a buckle or other snap-on structure, it can be snap-on with the slot 42 on the screw block. In addition, the design of the mounting position also takes into account the convenience and stability of operation. Whether it is a threaded connection or a snap-on connection, it can ensure that the connection between the insulating operating rod and the screw block is firm and reliable, avoiding operational errors or safety accidents caused by loose connections. In general, the spring pin 10 clamping device achieves reliable connection and remote control with the insulating operating rod by opening a mounting position on its screw block, further improving the operational flexibility and wide application scenarios of the device, and bringing more convenience and safety guarantees to the maintenance and inspection of the power system.

[0078] On the other hand, the present invention also provides a method for using a clamping device for a spring bayonet 10, using the clamping device for the spring bayonet 10 as described above, comprising the following steps:

[0079] S1: Connect the first guide rod 1 with the second guide rod 2 to ensure that their central axes are set at a preset angle (such as 90 degrees or other required angles) to form a stable support structure; the first guide rod 1 and / or the second guide rod 2 have sufficient flexibility at their connection points and can rotate relative to each other along themselves; the two ends of the connecting member 3 are respectively connected to the first guide rod 1 and the second guide rod 2, so that they can slide freely on the first guide rod 1 and the second guide rod 2 at the same time, and the three together form a dynamically stable triangular structure to adapt to different operational requirements.

[0080] S2: A clamping member 5 is provided on the first guide rod 1, and the clamping member 5 includes a first clamping jaw 51 and a second clamping jaw 52, ​​which are arranged in an "X" shape and are hinged to each other at a point in the middle, so that the top end of the first clamping jaw 51 is fixedly connected to the end of the first guide rod 1 by a fixed connecting member 3 (such as bolts, welding, etc.), and the top end of the second clamping jaw 52 is connected by a second ring 32 (or a similar structure) in the connecting member 3, so that when the second ring 32 slides on the first guide rod 1 or the second guide rod 2, it can drive the second clamping jaw 52 to move relative to the first clamping jaw 51, thereby changing the angle between the two; a driving member 4 is provided on the second guide rod 2, and the driving member 4 can be a screw block, a telescopic cylinder, a cylinder, etc., which is used to provide a driving force to push the connecting member 3 to slide.

[0081] S3: A connector 6 is provided at the intersection of the first guide rod 1 and the second guide rod 2, and the connector 6 is used to firmly connect the two together to adapt to different working angles; a fastener 7 (such as a bolt, a nut, a locking pin, etc.) is provided on the connector 6, and the first guide rod 1 and the second guide rod 2 can be limited and fixed by the fastener 7 to ensure that the relative position between the two remains stable during the operation.

[0082] S4: By operating the driving member 4 (such as rotating the screw block, starting the telescopic cylinder, etc.), the driving member 4 is moved along the second guide rod 2 (or the first guide rod 1, depending on the setting position of the driving member 4), and this movement will drive the connecting member 3 to slide on the first guide rod 1 and the second guide rod 2; since the connecting member 3 is connected to the second clamping jaw 52 (through the second sleeve ring 32), the sliding will cause the second clamping jaw 52 to move relative to the first clamping jaw 51, thereby changing the angle between the two, and realizing the opening or closing of the clamping member 5; when the clamping member 5 is closed, the first clamping jaw 51 and the second clamping jaw 52 will tightly clamp the spring bayonet 10 to achieve its clamping; when the clamping member 5 is opened, the spring bayonet 10 is released. During the whole process, the sliding of the connecting member 3 and the opening / closing action of the clamping member 5 are kept stable and accurate to ensure the effective clamping and release of the spring bayonet 10, which is convenient for the staff to clamp and place the spring bayonet when working at high altitude.

[0083] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
