Description

Technical Field

[0001] The invention relates to the technical field of tension wire clamps, and in particular to a compression type tension wire clamp. Background Art

[0002] Compression type tension clamps are mainly used for high-altitude wires. They are fixed by crimping the wire clamps to the wires. However, due to the long-term tension of the wires, the aluminum tubes are prone to breakage. After breaking, the entire line will be unable to supply power, resulting in a long-term power outage in the entire area.

[0003] Chinese Patent: CN202011098654.4 A method for analyzing and warning defects in a transmission line tension clamp discloses locations where conductors are prone to breakage, and discloses methods for defect analysis and warning.

[0004] Chinese Patent: CN202410436844.4 A method for analyzing and warning defects in tension clamps discloses that when a conductor breaks, the drain wire serves the purpose of the conductor so that the current can enter the jumper along the drain wire. However, although this method can prevent power outages in the area when the aluminum tube breaks. However, since the drain wire cannot limit the position of the breaking point, it is inconvenient for maintenance personnel to grab the breaking point at high altitude during subsequent maintenance, which is prone to danger. What is more troublesome is that the jumper will be subjected to the pulling force of the guide at this time, and the jumper itself will not be over-clamped between the wire clamp, which leads to the probability that the jumper will be pulled down by the wire and separated from the wire clamp, which will increase the difficulty of maintenance. Therefore, it is necessary to design a compression-type tension clamp, which can prevent the breaking point from being offset to a farther position after a break, and the wire will not exert a downward pulling force on the jumper after a break. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment: The present invention provides a compression type tension clamp, such as Figure 1 As shown, the connector 5 includes a body and a connector 5, wherein the connector 5 includes a steel tube 5a, an upper clamp 5b and a lower clamp 5c, wherein the upper clamp 5b is clamped on the aluminum tube 3, and the lower clamp 5c is clamped on the jumper 2, wherein the top of the steel tube 5a is hinged to the upper clamp 5b, and the bottom of the steel tube 5a is hinged to the lower clamp 5c, and a jumper tensioner 6 is fixedly arranged on the steel tube 5a, and the jumper tensioner 6 is hinged to the aluminum tube 3. When the aluminum tube region between the upper clamp 5b and the jumper tensioner 6 is broken, the wire 1 will pull the breaking point away from the wire clamp body by the tension, and due to the limiting effect of the jumper tensioner 6, the breaking point will not be able to leave a position far from the wire clamp. And before the breakage occurs, a triangular structure is formed between the connector 5, the jumper tensioner 6 and the steel pipe 5a, that is, when the breakage does not occur, the downward pulling force borne by the jumper 2 is reduced by supporting the lower clamp 5c, and the jumper 2 and the drainage tube 4 are prevented from being separated. And the jumper tensioner 6 and the connector 5 realize the triangular support structure of the wire clamp body, so that the overall rigidity of the wire clamp body is stronger. Therefore, through the role of the connector 5 and the jumper tensioner 6, the following effects are achieved: first, the breakage point is prevented from being far away from the wire clamp body; second, the jumper 2 is supported before the breakage occurs; and third, the overall rigidity of the wire clamp body is improved when there is no breakage.

[0027] Since the above scheme adopts the jumper tensioner 6 for support, this leads to a seesaw-like distance. Although the hinge point will not be too far away from the wire clamp body, the distance will still be far. At the same time, the bottom end of the steel pipe 5a will push up the jumper 2, which will cause friction and collision between the jumper 2 and the drainage tube 4. In order 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 tube 4. Through the action of the jumper tensioner 6 and the limit tensioner 7, after the breakage occurs, the swing amplitude of the steel pipe 5a is limited, so that the bottom of the steel pipe 5a will not move significantly, avoiding friction and collision between the jumper 2 and the drainage tube 4. And through the action of the limit tensioner 7, the area from the jumper tensioner 6 to the lower clamp 5c increases the support point, further increasing the bearing capacity.

[0028] And when the aluminum tube breaks, the wire still has a large pulling force, which causes it to break. The jumper tensioner 6 acts as the first supporting point, and the limit tensioner 7 acts as the second supporting point. Finally, the connection between the jumper 2 and the connector 5 acts as the last protective connection. Through these three protections, circuit breaking can be avoided.

[0029] In order to make the connector 5, the jumper tensioner 6 and the limit tensioner 7 applicable to the tension clamps of various angles, these parts can be processed in batches and can be used even if there is an angle error in the manufacturing of the clamps. Figure 2 As shown, the jumper tensioner 6 comprises a connecting rod 1 6a, a connecting rod 2 6b, a hinged rod 1 6c and an upper clamp 2 6d, the upper clamp 2 6d is clamped on the aluminum tube 3, the connecting rod 1 6a is fixedly mounted on the bottom of the upper clamp 2 6d, the connecting rod 2 6b is fixedly mounted on the steel tube 5a, one end of the hinged rod 1 6c is hinged to the connecting rod 1 6a, and the other end of the hinged rod 1 6c is hinged to the connecting rod 2 6b. By providing the hinged rod 1 6c, the hinge between the aluminum tube 3 and the steel tube 5a becomes a two-stage hinge, which increases the activity of the jumper tensioner 6.

[0030] like Figure 2 As shown, the position-limiting tensioner 7 comprises a connecting rod 3 7a, a connecting rod 4 7b, a hinged rod 2 7c and a lower clamp 2 7d, wherein the lower clamp 2 7d is clamped on the drainage tube 4, the connecting rod 3 7a is fixedly mounted on the bottom of the lower clamp 2 7d, the connecting rod 4 7b is fixedly mounted on the steel pipe 5a, one end of the hinged rod 2 7c is hinged to the connecting rod 3 7a, and the other end of the hinged rod 2 7c is hinged to the connecting rod 4 7b. By providing the hinged rod 2 7c, the hinge between the drainage tube 4 and the steel pipe 5a becomes a two-stage hinge, which increases the activity of the position-limiting tensioner 7.

[0031] By increasing the amount of movement of the jumper tensioner 6 and the limit tensioner 7, when adapting to the tension clamps at different angles, the upper clamp 5b, the upper clamp 6d, the upper clamp 6d and the lower clamp 5c can be mounted on the clamp without being fixed, so that they can be slid and adjusted on the clamp, so that the lower clamp 7d can wrap between the jumper 2 and the drainage tube 4, and the upper clamp 5b and the upper clamp 6d are both on the aluminum tube 3. After the above conditions are met, a tension clamp that can be applied to various angles is realized, and even if the tension clamp itself has an angle error in production, it can still be fixed on the tension clamp, ensuring that these parts can be processed in batches.

[0032] And through the structure of the jumper tensioner 6 and the limit tensioner 7, the steel pipe 5a can swing in a motion profile similar to a parallelogram. After the break occurs and when the wire 1 is blown by the wind, the force between the connecting rod 2 6b and the steel pipe 5a can be relieved by this shaking method, avoiding the instantaneous impact force from tearing it.

[0033] Due to the action of the jumper tensioner 6 and the limit tensioner 7, although the breaking point can be swung, the swing range is small. However, due to the frequent shaking of the jumper 2 pulled by the lower clamp 5c during the hours of waiting for maintenance, wrinkles will still be generated between the jumper 2 and the drainage tube 4. If the waiting time for maintenance is too long, there is a probability that the wrinkles will cause breakage. For this reason, Figure 2 As shown, it also includes a locker 8, one end of which is hinged to the middle of the hinge rod 1 6c, and two connection holes are provided on the aluminum tube 3 and the drainage tube 4, and the other end of the locker 8 is connected to one of the connection holes. By setting the locker 8, when a break occurs, the locker 8 locks the position of the hinge rod 1 6c, that is, the connecting rod 2 6b cannot move, which ensures that the limit tensioner 7 cannot move, that is, the steel tube 5a is locked, and the bottom of the jumper 2 is prevented from shaking, that is, the occurrence of wrinkles or breaks between the jumper 2 and the drainage tube 4 is avoided, and at the same time, the position of the break point is further limited, so that the break point can only rotate slightly.

[0034] like Figure 3 As shown, even with the addition of the locker 8, it can still be applied to tension clamps with various angles. When the angle changes significantly, the connection hole connected to the locker 8 can be replaced, and the number of connection holes can be adjusted as needed, not limited to two.

[0035] Since the steel pipe 5a is locked, when the conductor 1 is subjected to a large impact force at the moment, the sway buffer is lost, which will cause the connection between the steel pipe 5a and the connecting rod 6b to break. Figure 4-6As shown, the locker 8 includes a displacement tube 8a, a sleeve 8b, a pressure plate 8d, a positioning and pulling 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 hinge rod 6c, one end of the sleeve 8b is hinged to the connecting hole, the middle part of the displacement tube 8a is fixedly connected to the pressure plate 8d through a connecting column, a 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 mechanism 8e, the pressure plate 8d is transmission-connected to the positioning and pulling mechanism 8e, and when the pressure plate 8d is displaced to a preset position, the pressure plate 8d pushes the positioning and pulling mechanism 8e to separate from the retaining ring 8f. When the conductor 1 exerts a small impact force, the laminated spring 8c is compressed to a low degree. Although the pressure plate 8d slides along the sleeve 8b and squeezes the laminated spring 8c, the movement displacement of the pressure plate 8d is small, which will not cause the separation between the positioning and pulling mechanism 8e and the retaining ring 8f. When the pressure plate 8d has a large displacement, it means that the instantaneous impact force is large. At this time, it must be buffered by the swing of the steel pipe 5a, and this large impact force will often occur. Therefore, in the case of a large impact force, the positioning and pulling mechanism 8e and the retaining ring 8f are separated, and the retaining ring 8f no longer blocks the laminated spring 8c, that is, the displacement tube 8a and the sleeve 8b can slide freely, which means that the steel pipe 5a can swing freely, avoiding the breakage of the connection between the steel pipe 5a and the connecting rod 2 6b.

[0036] In order to enable the positioning and pulling mechanism 8e to be separated from the retaining ring 8f when the pressing plate 8d is displaced to the preset position, Figure 5 and Figure 6As shown, the positioning and pulling mechanism 8e includes an elastic pressing mechanism, a card plate 8e1, a column 8e2 and a push block 8e3. The column 8e2 is fixedly installed on the outer edge of the retaining ring 8f, and the sleeve 8b is provided with an avoidance groove 1 for horizontal sliding of the column 8e2. The push block 8e3 is fixedly installed on the outer edge of the pressure plate 8d. The sleeve 8b is provided with an avoidance groove 2 for horizontal sliding of the push block 8e3. The pressing mechanism is fixedly installed on the sleeve 8b, and the card plate 8e1 is fixedly installed on the bottom of the pressing mechanism. The card plate 8e1 is provided with a card hole for inserting the end of the column 8e2, and the bottom of the card plate 8e1 is provided with a trapezoidal protrusion 8e4 for contacting with the push block 8e3. When the displacement tube 8a is pulled horizontally, the push block 8e3 will be pulled to move horizontally, so that the push block 8e3 pushes the trapezoidal protrusion 8e4 to move outward, and the trapezoidal protrusion 8e4 will drive the card plate 8e1 to move outward, so that the card plate 8e1 and the plug post 8e2 are separated. After separation, the elastic force of the laminated spring 8c will push the retaining ring 8f away from the retaining hole to prevent the plug post 8e2 from being engaged with the card plate 8e1 again when the card plate 8e1 is lowered. The pushed plug post 8e2 will slide horizontally along the avoidance groove 1. At this time, the displacement tube 8a will not compress the laminated spring 8c regardless of whether it slides to the left or right. This is because the position of the retaining ring 8f at this time will not cause compression of the laminated spring 8c due to the small movement amplitude of 4a. The length of the avoidance groove 1 and the distance between the displacement tube 8a and the pressure 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 mechanism 8e can release the lock on the retaining ring 8f, and the release process is rapid. In addition, this intelligent release process does not require power supply, so that the wire clamp does not incur a large production cost.

[0038] like Figure 5 As shown, the elastic downward pressing 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, the two ends of the slide bar 8e5 are respectively inserted in the two side plates 8e9, and the side plates 8e9 are provided with a strip-shaped slide groove for the slide bar 8e5 to slide vertically, 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, and the spring 8e8 is used to apply a downward elastic force to the slide bar 8e5, and the spring 8e8 is sleeved on the outer edge of the guide post 8e6, one end of the spring 8e8 is in conflict with the slide bar 8e5, and the other end is in conflict with the guide plate 8e7. When the card plate 8e1 is pushed upward, the spring 8e8 will be compressed, and the vertical movement of the card plate 8e1 is guided by the slide bar 8e5 and the guide post 8e6.

[0039] like Figure 1 and Figure 2As shown, the upper clamp 1 5b, the upper clamp 2 6d and the lower clamp 2 7d have the same structure, and all include an upper semicircular plate and a lower semicircular plate, and the upper and lower semicircular plates are connected by bolts.

[0040] like Figure 1 As shown, the lower clamp 1 5c includes two rotating semicircular plates, one end of the two rotating semicircular plates is rotatably connected, one of the rotating semicircular plates is hingedly connected to the steel pipe 5a, and the other ends of the two rotating semicircular plates are connected by bolts. Through the structural design of the upper clamp 1 5b, the lower clamp 1 5c, the upper clamp 2 6d and the lower clamp 2 7d, when working at high altitude, the upper clamp 1 5b can be connected to the aluminum pipe 3 first, and then the lower clamp 1 5c can be buckled with the jumper 2, and finally the upper clamp 2 6d and the lower clamp 2 7d can be installed, and the whole installation process will not be difficult to install.

[0041] The compression type tension clamp improves the overall rigidity of the clamp body when there is no breakage, and supports the jumper. After the breakage, the connector and the jumper tensioner prevent the breakage point from shifting to a distant position, and after the breakage occurs, the wire will not exert a downward pulling force on the jumper. And through the action of the locker, when the breakage occurs, the locker locks the position of the hinged rod 1, so that the connecting rod 2 cannot move, which ensures that the limit tensioner cannot move, that is, the steel pipe is locked, and the bottom of the jumper is prevented from shaking, that is, wrinkles or breaks between the jumper and the drainage tube are prevented. At the same time, the position of the breakage point is further restricted, so that the breakage point can only rotate slightly. When the wire is instantly subjected to a large impact force, the positioning pull-up mechanism is separated from the retaining ring, and the retaining ring no longer blocks the laminated spring, that is, the displacement tube and the sleeve can slide freely, which means that the steel pipe can swing freely, and the connection between the steel pipe and the connecting rod 2 is prevented from breaking.

[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 equivalents, the present invention is also intended to include these modifications and variations.
