Description

Technical Field

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

[0002] The rotary suspension wire clamp is used to suspend and support the wire. However, due to the long-term friction between the rotating shaft and the hanging plate on the suspension wire clamp under the push of the wind, there is a probability that the hanging plate will be broken by friction at the bottom. Since the rotating shaft itself will be quenched to increase the rigidity, it will not break before the hanging plate. Therefore, avoiding the breakage of the hanging plate is a problem that needs to be solved. In the prior art, a bearing is generally installed between the rotating shaft and the hanging plate to reduce the occurrence of breakage through the bearing. However, the outer shell of the bearing generally needs to be fixedly connected to the hanging plate, which leads to the long-term use of the bearing, and the steel ball will produce long-term friction on the outer shell, which will still cause the bottom of the outer shell to be worn through. If the steel ball is worn, it will also cause the bearing to get stuck. The main reason for the failure of the above-mentioned bearing is that it has only one guarantee. Whether the steel ball or the outer shell is worn, it will cause the suspension wire clamp to fail, and this failure will cause the wire to be pulled off, and high-altitude maintenance is more difficult, resulting in more economic losses.

[0003] Therefore, it is necessary to design a rotary suspension wire clamp that can activate multiple safeguards to extend the service life of the suspension wire clamp and reduce the occurrence of faults. Summary of the invention

DETAILED DESCRIPTION

[0030] 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.

[0031] Embodiment: The present invention provides a rotary suspension clamp, such as Figure 1-5As shown, it includes a main body 1, a hanging plate 2, a rotating shaft 3, a rotating sleeve 4 and a pin 5. The rotating shaft 3 is fixedly installed on the main body 1. When the main body 1 rotates, it will drive the rotating shaft 3 to rotate synchronously. The rotating sleeve 4 is sleeved on the outer edge of the rotating shaft 3. The two ends of the rotating sleeve 4 are respectively in contact with the main body 1. The rotating sleeve 4 is inserted into the inner edge of the hanging plate 2. The hanging plate 2 is fixedly installed on the external frame by bolts. The pin 5 is clamped between the rotating shaft 3 and the rotating sleeve 4. The rotating shaft 3 is provided with a socket for the end of the pin 5 to be clamped. The end of the pin 5 is provided with an external thread. The rotating sleeve 4 is provided with a screw hole connected with the pin 5. The outer edge of the pin 5 is provided with a breaking groove 5a, and the breaking groove 5a is located between the rotating sleeve 4 and the rotating shaft 3. When the main body 1 drives the rotating shaft 3 to rotate, the rotating sleeve 4 will rotate along with the rotating shaft 3 due to the connection between the rotating shaft 3 and the rotating sleeve 4 by the bayonet 5. During the long-term rotation, the friction between the rotating sleeve 4 and the hanging plate 2 will cause the rotating shaft 3 to encounter resistance when driving the rotating sleeve 4 to rotate. The resistance will be converted into a shear force between the rotating shaft 3 and the rotating sleeve 4, and the shear force is mainly applied on the bayonet 5. Over time, the bayonet 5 that is continuously subjected to force will break along the fracture groove 5a. The friction between the rotating sleeve 4 and the hanging plate 2 will be converted into friction between the rotating sleeve 4 and the rotating shaft 3. Therefore, this can extend the service life of the suspension wire clamp and avoid the situation where the hanging plate 2 breaks due to continuous wear between the rotating sleeve 4 and the hanging plate 2. It should be explained that the rotary suspension wire clamp can also be used in fixed scenes of ground wires.

[0032] If only dry grinding is used between the hanging plate 2, the rotating shaft 3 and the rotating sleeve 4 without lubrication, the service life of the suspension wire clamp will be shortened. In order to lubricate the hanging plate 2, the rotating shaft 3 and the rotating sleeve 4 when they rotate, Figure 6 and Figure 2As shown, an annular oil storage chamber 4a is provided in the middle of the rotating sleeve 4, and solid grease is stored in the annular oil storage chamber 4a. Multiple arc-shaped oil guide grooves 4b are extended outward on both sides of the annular oil storage chamber 4a. The multiple arc-shaped oil guide grooves 4b are evenly distributed along the circumferential direction of the rotating shaft 3. The slot ends of the arc-shaped oil guide grooves 4b do not penetrate the ends of the rotating sleeve 4, and the fracture grooves 5a are located in the annular oil storage chamber 4a. When the bayonet 5 is broken along the fracture groove 5a, the rotating sleeve 4 and the rotating shaft 3 can rotate relative to each other. When the rotation occurs, the annular oil storage chamber 4a is slowly melted by the heat generated by friction, and the rotating shaft 3 and the rotating sleeve 4 are lubricated along the arc-shaped oil guide grooves 4b, thereby reducing the friction between the rotating shaft 3 and the rotating sleeve 4. The fracture grooves 5a are located in the annular oil storage chamber 4a, so that the cantilever beam of the bayonet 5 is extended, which is easier to control and break. When grease is first added to the annular oil storage chamber 4a, the bayonet pin 5 is removed, and grease is added along the threaded hole of the rotating sleeve 4. After the grease is added, the bayonet pin 5 is inserted to seal. After the bayonet pin 5 is broken, the threaded end of the bayonet pin 5 is still connected to the threaded hole on the rotating sleeve 4 to continue to play a sealing role. The arc-shaped oil guide groove 4b does not penetrate the rotating sleeve 4, mainly to keep the end of the arc-shaped oil guide groove 4b in a closed state to prevent grease from overflowing.

[0033] It should be noted that if the pin 5 breaks, friction will occur between the rotating shaft 3 and the rotating sleeve 4, and if the rotating sleeve 4 is in a non-rotating state, the contact position of the rotating shaft 3 on the rotating sleeve 4 is always constant, which leads to the probability that the bottom of the rotating sleeve 4 will be worn off. In order to further improve the service life of the suspension wire clamp, a one-way rotating mechanism 6 is provided at the end of the rotating sleeve 4, and a receiving groove 4c for accommodating the one-way rotating mechanism 6 is provided at the end of the rotating sleeve 4. When the rotating shaft 3 rotates clockwise, the one-way rotating mechanism 6 will drive the rotating sleeve 4 to move in the same direction, and when the rotating shaft 3 rotates counterclockwise, the rotating sleeve 4 stops moving. The rotating shaft 3 rotates, and then the one-way rotating mechanism 6 converts the movement of the rotating shaft 3, so that the clockwise rotation of the rotating shaft 3 can drive the rotating sleeve 4 to rotate clockwise together, and the rotating sleeve 4 will not be able to move when it rotates counterclockwise, avoiding the displacement driven by the rotating shaft 3 clockwise, and bringing it back when the rotating shaft 3 rotates counterclockwise.

[0034] If the rotating shaft 3 rotates counterclockwise, the rotating sleeve 4 will be driven to rotate, which will cause the rotating sleeve 4 to rotate all the time. Although it is not a reciprocating rotation, it is also a continuous rotation in one direction, which will still increase the friction burden between the rotating sleeve 4 and the hanging plate 2. In order to enable the rotating sleeve 4 to be driven to rotate, and the rotating sleeve 4 is not driven to rotate for a long time and continuously, the one-way rotating mechanism 6 includes a trapezoidal push block 6a and a plurality of trapezoidal transmission blocks 6b. The trapezoidal push block 6a can be slidably installed in the rotating shaft 3. A slide groove for radial sliding of the trapezoidal push block 6a is provided in the rotating shaft 3. The end of the trapezoidal push block 6a is vertically downward, and the plurality of trapezoidal transmission blocks 6b are fixedly installed on the inner wall of the rotating sleeve 4. When rotating clockwise, the plane end of the trapezoidal push block 6a contacts the plane end of the trapezoidal transmission block 6b. When rotating counterclockwise, the inclined surface end of the trapezoidal push block 6a contacts the inclined surface end of the trapezoidal transmission block 6b. The trapezoidal push block 6a can be driven to rotate by rotating the rotating shaft 3. When the trapezoidal push block 6a rotates, the trapezoidal push block 6a can only drive the rotating sleeve 4 to rotate clockwise through its own structure, but cannot rotate counterclockwise. In addition, when the wind force is small, the amplitude of the shaking of the main body 1 driven by the wire is small, which reduces the amplitude of the shaking of the rotating shaft 3 at the same time. Although the trapezoidal push block 6a can be driven to rotate, the trapezoidal push block 6a cannot move from one trapezoidal transmission block 6b to the next trapezoidal transmission block 6b, that is, reciprocate between the two trapezoidal transmission blocks 6b, and cannot drive the rotating sleeve 4 to rotate. This utilizes the shaking amplitude of the main body 1 to drive the rotating sleeve 4 to rotate only under strong wind conditions, avoiding the problem of driving the rotating sleeve 4 to rotate for a long time.

[0035] Although the annular oil storage chamber 4a stores a large amount of solid grease, the solid grease can only lubricate the space between the rotating shaft 3 and the rotating sleeve 4, but cannot lubricate the space between the rotating sleeve 4 and the hanging plate 2, which makes it easy for the two to wear and damage. Figure 8 , 9 As shown in FIG. 10 , a transverse groove 4f is provided on the outer edge of the rotating sleeve 4, and a vertical groove 4e for connecting the transverse groove 4f and the transverse groove 4f is provided inside the rotating sleeve 4. When the rotating sleeve 4 rotates, the grease in the annular oil storage chamber 4a will flow into the transverse groove 4f along the arc-shaped oil guide groove 4b and the vertical groove 4e, and then the rotating sleeve 4 rotates so that the transverse groove 4f rotates together, so that the grease in the transverse groove 4f can be evenly applied between the rotating sleeve 4 and the hanging plate 2, so as to achieve lubrication between the two and reduce wear and damage.

[0036] If the rotating shaft 3 and the rotating sleeve 4 can rotate relative to each other, the vertical groove 4e originally facing the lower surface will rotate toward the upper surface. At this time, the grease can be in contact with the air for a long time, which will cause the grease to be affected by the outside world and easily oxidized, resulting in grease failure. When the rotating shaft 3 and the rotating sleeve 4 are not separated, they are sealed by the hanging plate 2, so there is no need to worry. Therefore, when the rotating shaft 3 and the rotating sleeve 4 are separated, the vertical groove 4e can be automatically closed. For this reason, if Figure 8 , Fig.10 and Fig.11 As shown, the rotating sleeve 4 has a movable groove 4d connected to the vertical groove 4e, and an elastic closing mechanism 7 for closing the vertical groove 4e is arranged in the movable groove 4d. A vertical slide bar 3c is arranged in the rotating shaft 3, and the vertical slide bar 3c can be installed in the rotating shaft 3 in a vertical sliding manner. A strip-shaped slide groove for the vertical slide bar 3c to slide is provided in the rotating shaft 3. The side of the vertical slide bar 3c close to the elastic closing mechanism 7 is an inclined structure. The elastic closing mechanism 7 is provided with an inclined groove for the vertical slide bar 3c to be inserted into the inclined surface, and inclined grooves 4h extending outward are arranged on both sides of the vertical groove 4e. Fig.11 It can be seen that the vertical slide bar 3c forms a resistance trend to the elastic sealing mechanism 7, so that the elastic sealing mechanism 7 cannot close the vertical groove 4e, so that the grease can flow. If the bayonet 5 breaks, the rotating shaft 3 and the rotating sleeve 4 can rotate with each other, which makes the rotating shaft 3 drive the vertical slide bar 3c to rotate, and the vertical slide bar 3c will contact the inclined groove 4h, so that the vertical slide bar 3c is pushed upward into the rotating shaft 3 along the strip slide, so that the vertical slide bar 3c is retracted, so that the elastic sealing mechanism 7 can be resisted, and then the vertical groove 4e is closed, which can ensure that after the bayonet 5 breaks, when the vertical groove 4e rotates upward, it will not be oxidized by long-term contact with oxygen. Among them, in order to make the vertical slide bar 3c rotate better, the left and right ends of the two vertical slide bars 3c can be beveled inward at an angle, so that the vertical slide bar 3c can be better lifted upward.

[0037] like Fig.11 and Fig.12 As shown, the elastic closing mechanism 7 includes an extrusion block 7a, two guide posts 7b and two springs 7c. The extrusion block 7a is located in the movable groove 4d, and the two guide posts 7b can be installed on the rotating sleeve 4 in a horizontally slidable manner. One end of the two guide posts 7b is fixedly connected to the extrusion block 7a, and the spring 7c is used to apply an elastic force to the extrusion block 7a to squeeze the vertical slide bar 3c. When the vertical slide bar 3c is retracted upward, the spring 7c will push the extrusion block 7a so that the extrusion block 7a closes the vertical groove 4e. A through groove is provided on the side of the extrusion block 7a close to the rotating shaft 3, one end of the through groove is connected to the arc-shaped oil guide groove 4b, and the other end of the through groove is connected to the vertical groove 4e. When there is no closure, grease can pass through the through groove and enter the vertical groove 4e.

[0038] like Figure 4 As shown, an extrusion hole 3d is opened in the middle of the rotating shaft 3, and the extrusion hole 3d is connected with the strip slide groove for the vertical slide bar 3c to slide. At the initial installation, when the rotating shaft 3 is installed in place, the vertical slide bar 3c is still unable to push open the extrusion block 7a. At this time, a tool is inserted into the extrusion hole 3d, and the tool will push the vertical slide bar 3c downward, so that the inclined surface of the vertical slide bar 3c conflicts with the inclined surface of the extrusion block 7a, and the extrusion block 7a can be pushed open, so that the elastic closing mechanism 7 opens the vertical groove 4e.

[0039] like Figure 3 As shown, the rotating shaft 3 includes a screw 3a and a nut 3b. The end of the screw 3a is a polygonal structure. The body 1 is provided with a groove for the end of the screw 3a to be embedded. The nut 3b is meshed and installed on the end of the screw 3a, and one side of the nut 3b is in contact with the body 1. Through the action of the groove, a snap connection is formed between the screw 3a and the body 1, and when the body 1 rotates, the screw 3a will be driven to rotate together. In the process of inserting the screw 3a into the body 1, the one-way rotating mechanism 6 can be rotated toward the upper side, and then before the end of the screw 3a is about to be inserted into the groove, the one-way rotating mechanism 6 is rotated downward, which can prevent the one-way rotating mechanism 6 and the vertical slide bar 3c from sliding downward due to gravity.

[0040] like Figure 3 As shown, a clamping hole is provided on the screw 3a and penetrates the screw 3a. A steel wire 3e is installed in the clamping hole, and the steel wire 3e contacts one side of the nut 3b. When the body 1 is used for a long time, the nut 3b and the screw 3a may become loose due to vibration, and the nut 3b is limited by the steel wire 3e to prevent the nut 3b from loosening and displacement.

[0041] When in use, when the body 1 drives the rotating shaft 3 to rotate, the bayonet 5 connects the rotating shaft 3 and the rotating sleeve 4, so that the rotating sleeve 4 will rotate together. In the long-term rotation process, the rotating sleeve 4 and the hanging plate 2 will generate friction, which will cause the rotating shaft 3 to drive the rotating sleeve 4 to rotate. The resistance will be converted into a shear force between the rotating shaft 3 and the rotating sleeve 4, and the shear force is mainly applied on the bayonet 5. Over time, the bayonet 5 that is continuously stressed will break along the fracture groove 5a. The friction between the rotating sleeve 4 and the hanging plate 2 will be converted into friction between the rotating sleeve 4 and the rotating shaft 3.

[0042] When the rotating shaft 3 rotates, the one-way rotating mechanism 6 can drive the rotating sleeve 4 to rotate when the rotation amplitude is large, and the friction position of the rotating shaft 3 on the rotating sleeve 4 changes.

[0043] When the rotating shaft 3 drives the rotating sleeve 4 to rotate, the grease in the annular oil storage chamber 4a will flow into the transverse groove 4f along the vertical groove 4e to lubricate the rotating sleeve 4 and the hanging plate 2. After the bayonet 5 breaks, the rotating shaft 3 will rotate, so that the elastic sealing mechanism 7 will close the vertical groove 4e, and the grease will only lubricate the rotating shaft 3 and the rotating sleeve 4.

[0044] The rotary suspension wire clamp, when the conductor drives the body 1 to swing for a long time, the friction between the rotating sleeve 4 and the hanging plate 2 serves as the first protection. During the long-term friction, the latch 5 breaks, which is converted into friction between the rotating shaft 3 and the rotating sleeve 4, which serves as the second protection to avoid the risk of the hanging plate 2 being worn off. In order to prevent the rotating sleeve 4 from being worn off by the rotating shaft 3, the rotating sleeve 4 is driven to rotate by the one-way rotating mechanism 6 to avoid the rotating sleeve 4 having a single stress point and the one-way rotating mechanism 6 for a long time, which serves as the third protection. In addition, during the rotation process before the latch 5 breaks, the grease will lubricate the rotating sleeve 4 and the hanging plate 2 along the oil channel. After the latch 5 breaks, the elastic sealing mechanism 7 can be automatically closed to prevent the grease from being oxidized, ensuring that the grease can lubricate the rotating shaft 3 and the rotating sleeve 4 for a long time, so that the service life of the suspension wire clamp can be extended.

[0045] 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.
