Description

Technical Field

[0001] The present invention relates to the technical field of strain clamps, and particularly to a compression type strain clamp. Background Art

[0002] The compression type strain clamp is mainly used for high-altitude conductors, and is fixed between the clamp and the conductor by crimping. Due to the long-term load of the conductor's tensile force, its aluminum tube is prone to fracture. After the fracture, the entire line cannot be powered, resulting in a long-term power outage in the entire area.

[0003] Chinese Patent: CN202011098654.4, a method for analyzing and warning defects of a strain clamp for transmission lines, discloses the positions where the conductor is prone to fracture, and discloses the methods for defect analysis and warning.

[0004] Chinese Patent: CN202410436844.4, a method for analyzing and warning defects of a strain clamp, discloses that when the conductor fractures, the purpose of the conductor is achieved through a bypass wire, so that the current can enter the jumper along the bypass wire. Although this method can avoid power outages in the area when the aluminum tube fractures, since the bypass wire cannot limit the position of the fracture point, it is not convenient for maintenance personnel to grasp at high altitude during subsequent maintenance, and it is prone to danger. Even more troublesome is that the jumper will bear the tensile force of the conductor at this time, and the jumper itself will not be overly clamped with the clamp, which may cause the jumper to be pulled down by the conductor and separated from the clamp, increasing the maintenance difficulty. Therefore, it is necessary to design a compression type strain clamp that can prevent the fracture point from shifting to a far position after fracture and prevent the conductor from applying a downward tensile force to the jumper after fracture. Summary of the Invention

The column is fixedly installed on the outer edge of the retaining ring, and a first avoidance groove for horizontal sliding of the column is provided on the sleeve. The push block is fixedly installed on the outer edge of the pressure plate, and a second avoidance groove for horizontal sliding of the push block is provided on the sleeve.

Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment: The present invention provides a compression type strain clamp, as Figure 1 shown, including a body and a connector 5. The connector 5 includes a steel tube 5a, a first upper clamp 5b and a first lower clamp 5c. The first upper clamp 5b is clamped on the aluminum tube 3, and the first lower clamp 5c is clamped on the jumper wire 2. The top end of the steel tube 5a is hinged to the first upper clamp 5b, and the bottom end of the steel tube 5a is hinged to the first lower clamp 5c. A jumper wire tensioner 6 is fixedly arranged on the steel tube 5a, and the jumper wire tensioner 6 is hinged to the aluminum tube 3. When the aluminum tube area between the first upper clamp 5b and the jumper wire tensioner 6 breaks, the wire 1 will pull the break point away from the clamp body through the tension, and due to the limiting effect of the jumper wire tensioner 6, the break point will not be able to leave the clamp too far. And before the break occurs, a triangular structure is formed among the connector 5, the jumper wire tensioner 6 and the steel tube 5a, that is, before the break occurs, by supporting the first lower clamp 5c, the downward tension borne by the jumper wire 2 is reduced, and the separation between the jumper wire 2 and the drainage tube 4 is avoided. And through the jumper wire tensioner 6 and the connector 5, a triangular support structure is realized for the clamp body, making the overall rigidity of the clamp body stronger. Therefore, through the action of the connector 5 and the jumper wire tensioner 6, the following effects are achieved: firstly, the break point is prevented from moving away from the clamp body; secondly, the jumper wire 2 is supported before the break; thirdly, the overall rigidity of the clamp body is improved when there is no break.

[0027] Since the above solution uses the jumper tensioner 6 for support, this results in a situation similar to a seesaw moving away. Although the hinge point will not move too far away from the clamp body, the distance will still be relatively large. At the same time, the bottom end of the steel pipe 5a will push up the jumper wire 2, that is, it will cause friction and collision between the jumper wire 2 and the drainage pipe 4. To solve this problem, a limit tensioner 7 is also included. The limit tensioner 7 is fixedly installed on the connector 5, and one end of the limit tensioner 7 is hinged to the drainage pipe 4. Through the action of the jumper tensioner 6 and the limit tensioner 7, after a fracture occurs, the swinging amplitude of the steel pipe 5a is restricted, so that the bottom of the steel pipe 5a will not move significantly, avoiding friction and collision between the jumper wire 2 and the drainage pipe 4. And through the action of the limit tensioner 7, in the area from the jumper tensioner 6 to the lower clamp 5c, the support points are increased, further increasing the bearing capacity.

[0028] And when the aluminum pipe breaks, the wire still has a relatively large tensile force, which still leads to fracture. Through the action of the jumper tensioner 6, it plays the role of the first support point, and through the action of the limit tensioner 7, it plays the role of the second support point. Finally, the connection between the jumper wire 2 and the connector 5 plays the role of the last protection connection. Through these three protections, the situation of open circuit is avoided.

[0029] Among them, in order for the connector 5, the jumper tensioner 6 and the limit tensioner 7 to be applicable to strain clamps at various angles, so that these parts can be mass-produced, and even if there are manufacturing angle errors in the clamps, they can still be used. Therefore, as Figure 2 shown, the jumper tensioner 6 includes a connecting rod 6a, a connecting rod 6b, a hinge rod 6c and an upper clamp 6d. The upper clamp 6d clamps on the aluminum pipe 3. The connecting rod 6a is fixedly installed at the bottom of the upper clamp 6d. The connecting rod 6b is fixedly installed on the steel pipe 5a. One end of the hinge rod 6c is hinged to the connecting rod 6a, and the other end of the hinge rod 6c is hinged to the connecting rod 6b. By setting the hinge rod 6c, the hinge between the aluminum pipe 3 and the steel pipe 5a becomes a two-stage hinge, which increases the movement amount of the jumper tensioner 6.

[0030] As Figure 2 shown, the limit tensioner 7 includes a connecting rod 7a, a connecting rod 7b, a hinge rod 7c and a lower clamp 7d. The lower clamp 7d clamps on the drainage pipe 4. The connecting rod 7a is fixedly installed at the bottom of the lower clamp 7d. The connecting rod 7b is fixedly installed on the steel pipe 5a. One end of the hinge rod 7c is hinged to the connecting rod 7a, and the other end of the hinge rod 7c is hinged to the connecting rod 7b. By setting the hinge rod 7c, the hinge between the drainage pipe 4 and the steel pipe 5a becomes a two-stage hinge, which increases the movement amount of the limit tensioner 7.

[0031] Moreover, the movement ranges of both the jumper tensioner 6 and the limit tensioner 7 increase. This allows, when adapting to strain clamps at different angles, the upper gripper one 5b, the upper gripper two 6d, and the lower gripper one 5c to be sleeved on the strain clamp without being fixed, enabling them to slide and adjust their positions on the strain clamp. This ensures that the lower gripper two 7d can wrap around between the jumper 2 and the drainage pipe 4, and both the upper gripper one 5b and the upper gripper two 6d are on the aluminum pipe 3. After meeting the above conditions, it realizes the ability to be applicable to strain clamps at various angles. And even if there are production angle errors in the strain clamp itself, it can still be fixed on the strain clamp, ensuring that these parts can be mass-produced.

[0032] Furthermore, due to the structures of the jumper tensioner 6 and the limit tensioner 7, the steel pipe 5a can swing with a movement profile similar to that of a parallelogram. After a fracture occurs and when the conductor 1 is blown by the wind, through this swaying method, the force between the connecting rod two 6b and the steel pipe 5a can be relieved, preventing the instantaneous impact force from splitting it.

[0033] Due to the actions of the jumper tensioner 6 and the limit tensioner 7, although the fracture point can be made to swing and the swing range is small, during the several hours that the lower gripper one 5c waits for repair, the frequent swaying of the lower gripper one 5c pulling the jumper 2 will still cause wrinkles to form between the jumper 2 and the drainage pipe 4. And if the waiting time for repair is too long, there is a probability that the wrinkles will break. Therefore, as Figure 2 shown, it also includes a lock 8. One end of the lock 8 is hinged to the middle of the hinge rod one 6c. Two connection holes are opened on both the aluminum pipe 3 and the drainage pipe 4. The other end of the lock 8 is connected to one of the connection holes. By setting the lock 8, when a fracture occurs, since the lock 8 locks the position of the hinge rod one 6c, it ensures that the connecting rod two 6b cannot move, which in turn guarantees that the limit tensioner 7 and the steel pipe 5a cannot move and are locked, preventing the bottom of the jumper 2 from swaying, that is, avoiding the occurrence of wrinkles or fractures between the jumper 2 and the drainage pipe 4. At the same time, the position of the fracture point is further restricted, allowing the fracture point to only rotate slightly.

[0034] If Figure 3 shown, even with the addition of the lock 8, it can still be applicable to strain clamps at various angles. When the angle changes significantly, the connection hole to which the lock 8 is connected can be replaced, and the number of connection holes can also be determined as needed, not limited to two.

[0035] Since the steel pipe 5a is locked, in the case of a large instantaneous impact force exerted by the conductor 1, due to the loss of the swaying buffer, this will cause the connection between the steel pipe 5a and the connecting rod two 6b to break. Therefore, as Figures 4 - 6As shown, the locking device 8 includes a displacement tube 8a, a sleeve 8b, a pressing plate 8d, a positioning and pulling-up mechanism 8e, a retaining ring 8f, and a plurality of laminated springs 8c. The displacement tube 8a is inserted into the sleeve 8b. One end of the displacement tube 8a is hinged to the first articulated rod 6c, and one end of the sleeve 8b is hinged to the connection hole. The middle part of the displacement tube 8a is fixedly connected to the pressing plate 8d through a connecting column. The plurality of laminated springs 8c are sleeved on the connecting column. The retaining ring 8f is fixedly installed on the outer edge of the sleeve 8b through the positioning and pulling-up mechanism 8e. The pressing plate 8d is in transmission connection with the positioning and pulling-up mechanism 8e. When the pressing plate 8d is displaced to a preset position, the pressing plate 8d pushes the positioning and pulling-up mechanism 8e to separate from the retaining ring 8f. When a small impact force is applied to the wire 1, the degree of compression of the laminated springs 8c is relatively low. Although the pressing plate 8d slides along the sleeve 8b and squeezes the laminated springs 8c, since the movement displacement of the pressing plate 8d is small, it will not cause the separation between the positioning and pulling-up mechanism 8e and the retaining ring 8f. When the pressing plate 8d has a large displacement, it means that the instantaneous impact force is large. At this time, buffering must be carried out through the swing of the steel pipe 5a, and this large impact force often occurs. Therefore, in the case of a large impact force, the positioning and pulling-up mechanism 8e and the retaining ring 8f are separated, and the retaining ring 8f no longer blocks the laminated springs 8c, that is, the displacement tube 8a and the sleeve 8b can slide freely, indicating that the steel pipe 5a can swing freely, avoiding the fracture at the connection between the steel pipe 5a and the second connecting rod 6b.

[0036] In order to enable the positioning and pulling-up mechanism 8e to separate from the retaining ring 8f when the pressing plate 8d is displaced to a preset position, therefore, as Figure 5 and Figure 6As shown in the figure, the positioning and pulling-up mechanism 8e includes an elastic pressing-down mechanism, a clamping plate 8e1, a plug post 8e2, and a pushing block 8e3. The plug post 8e2 is fixedly installed on the outer edge of the retaining ring 8f. An avoidance groove one for the horizontal sliding of the plug post 8e2 is provided on the sleeve 8b. The pushing block 8e3 is fixedly installed on the outer edge of the pressing plate 8d. An avoidance groove two for the horizontal sliding of the pushing block 8e3 is provided on the sleeve 8b. The pressing-down mechanism is fixedly installed on the sleeve 8b. The clamping plate 8e1 is fixedly installed at the bottom of the pressing-down mechanism. A clamping hole for the end of the plug post 8e2 to insert is provided on the clamping plate 8e1. A trapezoidal convex block 8e4 for abutting against the pushing block 8e3 is provided at the bottom of the clamping plate 8e1. When the displacement tube 8a is horizontally pulled, the pushing block 8e3 will be pulled to move horizontally, so that the pushing block 8e3 pushes the trapezoidal convex block 8e4 to move outwards, and the trapezoidal convex block 8e4 will drive the clamping plate 8e1 to move outwards, so that the clamping plate 8e1 and the plug post 8e2 are separated. After the separation, the elastic force of the laminated spring 8c will push the retaining ring 8f away from the clamping hole to prevent the plug post 8e2 from being clamped with the clamping plate 8e1 again when the clamping plate 8e1 descends. The pushed plug post 8e2 will slide horizontally along the avoidance groove one. At this time, whether the displacement tube 8a slides to the left or right, it will not compress the laminated spring 8c. This is because, due to the small movement amplitude of 4a, the position where the retaining ring 8f is located at this time will not cause extrusion of the laminated spring 8c. The length of the avoidance groove one and the distance between the displacement tube 8a and the pressing plate 8d can be changed as needed to ensure that the laminated spring 8c is not compressed.

[0037] By pulling the displacement tube 8a, the positioning and pulling-up mechanism 8e can release the locking of the retaining ring 8f, and the release process is rapid. Moreover, this intelligent release process does not require power supply, so that the production cost of this wire clamp will not be too high.

[0038] As Figure 5 shown, the elastic pressing-down mechanism includes a slide bar 8e5, a guide post 8e6, a guide plate 8e7, and a spring 8e8. Two side plates 8e9 are fixedly arranged on both sides of the sleeve 8b. Both ends of the slide bar 8e5 are respectively inserted into the two side plates 8e9. A strip-shaped chute for the vertical sliding of the slide bar 8e5 is provided on the side plate 8e9. The guide plate 8e7 is fixedly installed on the top of the side plate 8e9. The guide post 8e6 is slidably connected with the guide plate 8e7. The bottom of the guide post 8e6 is fixedly connected with the slide bar 8e5. The spring 8e8 is used to apply a downward elastic force to the slide bar 8e5. The spring 8e8 is sleeved on the outer edge of the guide post 8e6. One end of the spring 8e8 abuts against the slide bar 8e5, and the other end abuts against the guide plate 8e7. When the clamping plate 8e1 is pushed upwards, the spring 8e8 will be compressed, and the vertical movement of the clamping plate 8e1 is guided through the slide bar 8e5 and the guide post 8e6.

[0039] As Figure 1 and Figure 2As shown, the upper clamp one 5b, the upper clamp two 6d and the lower clamp two 7d have the same structure, each including an upper semi-circular plate and a lower semi-circular plate, which are connected by bolts between the upper and lower semi-circular plates.

[0040] As Figure 1 shown, the lower clamp one 5c includes two rotating semi-circular plates. One end of the two rotating semi-circular plates is rotatably connected. One of the rotating semi-circular plates is hinged to the steel pipe 5a, and the other ends of the two rotating semi-circular plates are connected by bolts. Through the structural design of the upper clamp one 5b, the lower clamp one 5c, the upper clamp two 6d and the lower clamp two 7d, during high-altitude operation, the upper clamp one 5b can be first connected to the aluminum pipe 3, then the lower clamp one 5c can be buckled to the jumper wire 2, and finally the upper clamp two 6d and the lower clamp two 7d can be installed. Difficult installation situations will not occur during the entire installation process.

[0041] For this compression type strain clamp, when there is no fracture, the overall rigidity of the clamp body is improved, and the jumper wire is supported. After fracture, through the action of the connector and the jumper wire tensioner, it is avoided that the fracture point will not shift to a far position, and after fracture, the conductor will not apply a downward pulling force on the jumper wire. And through the action of the locking device, when fracture occurs, since the locking device locks the position of the hinged rod one, the connecting rod two cannot move, which ensures that the limit tensioner cannot move either, that is, the steel pipe is locked, avoiding the bottom of the jumper wire from shaking, that is, avoiding the occurrence of wrinkles or fractures between the jumper wire and the drainage pipe. At the same time, the position of the fracture point is further restricted, making the fracture point can only rotate slightly. In the case of a large impact force instantaneously applied by the conductor, the positioning upper pulling mechanism is separated from the retaining ring, and the retaining ring no longer blocks the laminated spring, that is, the displacement pipe and the sleeve can slide freely, indicating that the steel pipe can swing freely, avoiding fracture at the connection between the steel pipe and the connecting rod two.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
