Description

Technical Field

[0001] The utility model relates to the technical field of spacer bars, in particular to a spacer bar. Background Art

[0002] In overhead ultra-high voltage transmission, compared with a single conductor, split conductors can reduce the inductance and increase the capacitance of the transmission line, reduce its wave impedance to AC power, and improve the transmission capacity of the line. Therefore, split conductors are generally used. However, split conductors often dance under the action of wind, which will produce excessive tension on the conductors, causing the conductors to short or drop due to fatigue accumulation, or cause the conductors to whip each other. In severe cases, this dancing phenomenon will cause mechanical damage to transmission equipment such as tower components and insulator strings. What's more, the dancing will cause the tower to collapse. The current effective way to prevent the dancing of transmission lines is to install spacers on the split conductors. However, traditional spacers usually need to manually lock the wire clamps of the spacers after clamping the conductors, resulting in cumbersome installation and inefficiency of the spacer operation.

[0005] Preferably, the main body is provided with a first connecting hole, the first wire clamp includes a first connecting portion, the first connecting portion is provided with a second connecting hole and a first connecting piece, and the first connecting hole, the second connecting hole and the first connecting piece are rotatably matched.

[0006] Preferably, a limiting hole is provided on the main body, the limiting hole is axially parallel to the first connecting hole, a limiting piece is provided on the first connecting portion, and when the limiting piece cooperates with the limiting hole, a movable gap exists in the limiting hole.

[0007] Preferably, the telescopic pin is arranged along the length direction of the first wire clamp.

[0008] Preferably, the telescopic latch comprises a telescopic rod and a latch block connected to each other, and a limiting protrusion is provided on the telescopic rod.

[0009] Preferably, one end of the latch block close to the fixing groove is an inclined surface.

[0010] Preferably, the telescopic rod is provided with an elastic member abutting against the limiting protrusion.

[0011] Preferably, the first wire clamp includes a second connecting portion connected to the first connecting portion, the second connecting portion has a hollow chamber, the second wire clamp is partially accommodated in the hollow chamber, and the hollow chamber is provided with a limiting boss near one end of the second wire clamp.

[0012] Preferably, a rotating arc surface is provided on the end surface of the second wire clamp close to the limiting boss.

[0013] Preferably, the first wire clamp and the second wire clamp are both provided with a grabbing clamp at one end away from the main body, and an elastic pad is provided inside the grabbing clamp.

[0014] Compared with the prior art, the spacer rod of the utility model has the following advantages:

[0015] The utility model discloses a spacer rod, comprising a main body and a wire clamp rotatably connected to the main body, the wire clamp comprising a first wire clamp and a second wire clamp rotatably connected to the main body, the first wire clamp is provided with a receiving groove, a telescopic latch is provided in the receiving groove, a fixing groove is provided at one end of the second wire clamp close to the telescopic latch, a limiting baffle is provided at one end of the fixing groove away from the first wire clamp, when the second wire clamp is rotated relative to the first wire clamp until the fixing groove is connected to the receiving groove, the telescopic latch at least partially enters the fixing groove.

[0016] It can be understood that when the first wire clamp and the second wire clamp are in the open state, the limit baffle is in abutment with the telescopic pin, compressing the telescopic pin into the accommodating groove. When the second wire clamp is rotated to clamp the first wire clamp, the fixed groove is connected with the accommodating groove as the second wire clamp rotates. At this time, the limit baffle is also separated from the abutment with the telescopic pin, so that the telescopic pin extends in the direction of the fixed groove and partially enters the fixed groove. By cooperating with the current position of the limit baffle and the telescopic pin, the second wire clamp can be limited from rotating in a direction away from the first wire clamp, so that the first wire clamp and the second wire clamp remain in a clamped state.

[0017] 2. In the spacer bar of the utility model, a first connecting hole is provided on the main body, and a first wire clamp includes a first connecting portion, and a second connecting hole and a first connecting member are provided on the first connecting portion, and the first connecting hole and the second connecting hole are rotatably matched with the first connecting member. The first wire clamp is fixed to the main body through the hole-axis matching of the first connecting hole, the second connecting hole and the first connecting member, and is rotatably connected with the main body, so as to facilitate the adjustment of the angle of the wire clamp.

[0018] 3. A limiting hole is provided on the main body of the spacer rod of the utility model. The limiting hole is axially parallel to the first connecting hole. A limiting piece is provided on the first connecting part. When the limiting piece cooperates with the limiting hole, there is a movable gap in the limiting hole, so that the wire clamp can rotate within a preset range. The cooperation between the limiting hole and the limiting piece limits the rotation angle of the wire clamp relative to the main body to a certain extent, thereby avoiding a large rotation of the wire clamp that reduces the spacing effect on the wires.

[0019] 4. The telescopic latch in the spacer bar of the utility model comprises a telescopic rod and a latch block connected to each other, and the telescopic rod is provided with a limiting protrusion and an elastic member abutting against the limiting protrusion.

[0020] It can be understood that when the telescopic pin is supported by the limiting baffle and retracted in the accommodating groove, the limiting protrusion compresses the elastic member to deform as the telescopic pin contracts. When the limiting baffle no longer supports the telescopic pin, the elastic member is not compressed and returns to its original state to push the telescopic pin to extend outward into the fixed groove.

[0021] 5. The end of the pin block in the spacer bar of the utility model close to the fixed groove is an inclined surface. During the rotation of the second wire clamp, the limit baffle plate abuts against the telescopic pin along the inclined surface, so that the second wire clamp rotates smoothly and the telescopic pin is gradually retracted.

[0022] 6. The first wire clamp in the spacer rod of the utility model includes a second connecting part connected to the first connecting part, the second connecting part has a hollow chamber, the second wire clamp is partially accommodated in the hollow chamber, and a limiting boss is provided at one end of the hollow chamber close to the second wire clamp to limit the second wire clamp from rotating too close to the first wire clamp. When the telescopic pin cooperates with the fixed groove, the pin block and the limiting boss both limit the limiting baffle, so that the wire clamp maintains the current clamping state.

[0023] 7. In the spacer bar of the utility model, a rotation arc surface is provided on the end surface of the second wire clamp close to the limiting boss to prevent the corresponding end surface of the second wire clamp from colliding with the limiting boss during rotation, thereby preventing the rotation from being interrupted.

[0024] 8. The first wire clamp and the second wire clamp in the spacer rod of the utility model are both provided with a gripping clamp at one end away from the main body, and an elastic pad is provided inside the gripping clamp, which can increase the contact area and friction with the wire when clamping the wire, facilitate the fixation of the wire and prevent the wire from falling off, and at the same time provide a certain buffering effect on the wire to avoid excessive squeezing, damage to the wire, and affect the use of the wire.

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0038] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0039] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0040] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] See also Figure 1 , Figure 2 and Figure 4 The first embodiment of the utility model provides a spacer bar 100, including a main body 1 and a wire clamp 2 rotatably connected to the main body 1, the wire clamp 2 includes a first wire clamp 21 and a second wire clamp 22 rotatably connected thereto, the first wire clamp 21 is provided with a receiving groove 211, and a telescopic pin 3 is provided in the receiving groove 211. Specifically, the telescopic pin 3 is arranged along the length direction of the first wire clamp 21, and a fixing groove 221 is provided at one end of the second wire clamp 22 close to the telescopic pin 3, and a limiting baffle 222 is provided at one end of the fixing groove 221 away from the first wire clamp 21. When the second wire clamp 22 rotates relative to the first wire clamp 21 until the fixing groove 221 is connected to the receiving groove 211, the telescopic pin 3 at least partially enters the fixing groove 221 and cooperates with the limiting baffle 222 to maintain the second wire clamp 22 in the current state.

[0042] It can be understood that when the first wire clamp 21 and the second wire clamp 22 are in the open state, the limit baffle 222 abuts against the telescopic pin 3 to compress the telescopic pin 3 into the accommodating groove 211. When the second wire clamp 22 rotates to clamp the first wire clamp 21, the fixed groove 221 is connected to the accommodating groove 211 as the second wire clamp 22 rotates. At this time, the limit baffle 222 also breaks away from the abutment against the telescopic pin 3, so that the telescopic pin 3 extends in the direction of the fixed groove 221 and partially enters the fixed groove 221. By cooperating with the current position of the limit baffle 222 and the telescopic pin 3, the second wire clamp 22 can be limited from rotating in a direction relatively away from the first wire clamp 21, so that the first wire clamp 21 and the second wire clamp 22 remain in the clamped state.

[0043] In a specific embodiment, the main body 1 is two hexagonal steel plates, which are arranged in parallel and are clamped and connected with a grabbing clip 23 at each corner.

[0044] In other feasible embodiments, the main body 1 can be one or more plates, and its shape can be a long strip, a quadrilateral or other shapes. The material can be metal or non-metal such as iron, copper, chromium, etc., as long as it can cooperate with the wire clamp 2 to space the wires. There are no excessive restrictions on its specific shape, material, etc., and it can be set according to actual conditions. In particular, the number of wire clamps 2 is usually matched with the number of high-voltage cables to be spaced, that is, two, four or six.

[0045] Furthermore, the main body 1 is provided with a first connecting hole 11, the first wire clamp 21 includes a first connecting portion 212, the first connecting portion 212 is provided with a second connecting hole 2121 and a first connecting member 2122, and the first connecting hole 11, the second connecting hole 2121 and the first connecting member 2122 are rotatably matched.

[0046] It should be noted that, in the present embodiment, the first connecting member 2122 is specifically a connecting shaft. When the first wire clamp 21 is installed with the main body 1, the first connecting hole 11 and the second connecting hole 2121 are coaxial. The first connecting member 2122 passes through the first connecting hole 11 and the second connecting hole 2121 to connect the first wire clamp 21 with the main body 1, and the hole-axis cooperation of the first connecting hole 11, the second connecting hole 2121 and the first connecting member 2122 is a rotational cooperation, so that the first wire clamp 21 can rotate relative to the main body 1, so as to adjust the angle of the wire clamp 2 and facilitate the wire clamp 2 to grab the wire.

[0047] Furthermore, a limiting hole 12 is provided on the main body 1 , and the limiting hole 12 is axially parallel to the first connecting hole 11 . A limiting member 2123 is provided on the first connecting portion 212 . When the limiting member 2123 cooperates with the limiting hole 12 , there is a movable gap between the limiting hole 12 and the limiting member 2123 .

[0048] In a specific embodiment, the limiting member 2123 is a cylinder arranged on the first connecting portion 212. After the first wire clamp 21 is connected to the main body 1, the limiting member 2123 is correspondingly arranged in the limiting hole 12, and the limiting hole 12 has a movable gap in the movable direction of the limiting member 2123. When the first wire clamp 21 rotates, it will drive the limiting member 2123 to rotate. When the limiting member 2123 rotates to abut against the inner wall of the limiting hole 12, it cannot continue to move, so that the first wire clamp 21 cannot continue to rotate.

[0049] Specifically, the inner diameter of the limiting hole 12 is larger than the outer diameter of the limiting member 2123, so that when the limiting member 2123 is installed in the limiting hole 12, there is a movable gap in the limiting hole 12 for the limiting member 2123 to move, so that the wire clamp 2 can rotate within a preset range. The cooperation between the limiting hole 12 and the limiting member 2123 limits the rotation angle of the wire clamp 2 relative to the main body 1 to a certain extent, thereby preventing the wire clamp 2 from rotating significantly and causing a reduction in the spacing effect on the wires.

[0050] Specifically, the limiting member 2123 may be in the shape of a cuboid, a truncated cone, etc. It may be integrally formed with the first connecting portion 212 or fixedly connected or detachably connected. As long as it can cooperate with the limiting hole 12 to limit the rotation of the first wire clamp 21, no excessive restrictions are imposed here.

[0051] Further, please join us Figure 3 The telescopic latch 3 includes a telescopic rod 31 and a latch block 32 connected to each other, and a limiting protrusion 311 is provided on the telescopic rod 31.

[0052] In a feasible embodiment, the accommodating groove 211 is arranged along the length direction of the first connecting part 212 and passes through the first connecting part 212, and the telescopic pin 3 is installed in the accommodating groove 211, wherein the telescopic rod 31 is arranged at the end of the accommodating groove 211 close to the main body 1, and the pin block 32 is arranged at the end away from the main body 1. Specifically, a limit block is provided on the end of the telescopic rod 31 close to the main body 1 so that the end face of the telescopic rod 31 close to the main body 1 cannot be retracted into the accommodating groove 211, thereby preventing the telescopic pin 3 from excessively extending in the direction away from the main body 1 or even detaching from the accommodating groove 211. At the same time, the limit block allows part of the telescopic rod 31 to remain outside the accommodating groove 211, so that the clamping state of the wire clamp 2 can be released by stretching this part of the telescopic rod 31.

[0053] Furthermore, the telescopic rod 31 is provided with an elastic member 312 which abuts against the limiting protrusion 311 .

[0054] Optionally, the elastic member 312 may be one or more of a coil spring, a torsion bar spring, a rubber spring, a spring sheet or other elastic parts.

[0055] It should be noted that when the limit baffle 222 is in contact with the telescopic pin 3, the telescopic pin 3 is retracted by the supporting force, so that the limit protrusion 311 on the telescopic rod 31 presses against the compressed elastic member 312 to cause it to undergo elastic deformation; when the second wire clamp 22 is rotated until the fixed groove 221 is connected to the accommodating groove 211, the limit baffle 222 is not in contact with the telescopic pin 3, that is, the telescopic pin 3 is no longer subjected to the supporting force, and the previously compressed elastic member 312 returns to its original state under the action of the elastic force, and pushes the telescopic pin 3 to extend toward the fixed groove 221 and enter the fixed groove 221 through the limit protrusion 311.

[0056] It should be understood that when the telescopic pin 3 partially enters the fixed groove 221, if the second wire clamp 22 is to be rotated relative to the opening direction of the first wire clamp 21, the limit baffle 222 will abut against the pin block 32 entering the fixed groove 221 to limit the rotation of the second wire clamp 22.

[0057] Furthermore, one end of the latch block 32 close to the fixing groove 221 is a slope 321 .

[0058] It can be understood that during the rotation of the second wire clamp 22, the limit baffle 222 abuts against the telescopic pin 3 along the inclined surface 321, and as the second wire clamp 22 rotates, the telescopic pin 3 gradually retracts. It should be understood that the inclined surface 321 can make the contact surface between the second wire clamp 22 and the telescopic pin 3 smooth when the second wire clamp 22 rotates, thereby allowing the second wire clamp 22 to rotate smoothly.

[0059] Optionally, the inclination angle of the inclined surface 321 may be 30°, 45°, 60° or other angles.

[0060] Preferably, the inclined surface 321 in this embodiment has an inclination angle of 45°, so that the telescopic latch 3 retracts at a uniform speed and is evenly stressed as the second wire clamp 22 rotates.

[0061] Further, please refer to Figure 2 and Figure 4 The first wire clamp 21 includes a second connecting portion 213 connected to the first connecting portion 212, the second connecting portion 213 has a hollow chamber 2131, the second wire clamp 22 is partially accommodated in the hollow chamber 2131, and a limiting boss 2132 is provided in the hollow chamber 2131 near one end of the second wire clamp 22.

[0062] In a specific embodiment, the second connecting portion 213 connected to the first connecting portion 212 is integrally formed, the second connecting portion 213 is provided with a third connecting hole and a second connecting piece, the second wire clamp 22 is provided with a fourth connecting hole, and the third connecting hole, the fourth connecting hole and the second connecting piece cooperate to rotatably connect the first wire clamp 21 and the second wire clamp 22.

[0063] It can be understood that when the second wire clamp 22 rotates a certain angle in the direction close to the first wire clamp 21, the limit baffle 222 will abut against the limit boss 2132 to limit the second wire clamp 22 from continuing to rotate, thereby preventing the second wire clamp 22 from getting too close to the first wire clamp 21, causing the wire clamp 2 to excessively clamp the wire and cause damage to the wire.

[0064] In particular, when the wire clamp 2 is in the clamped state, the limit baffle 222 on the second wire clamp 22 is just located between the latch block 32 and the limit boss 2132, respectively limiting the two rotation directions of the second wire clamp 22, so that the second wire clamp 22 cannot rotate, thereby firmly maintaining the current clamping state.

[0065] Please also refer to Figure 5 A rotating arc surface 223 is provided on the end surface of the second wire clamp 22 close to the limiting boss 2132.

[0066] It can be understood that the rotation arc surface 223 is provided at the position corresponding to the second wire clamp 22 and the limiting boss 2132 so that the limiting boss 2132 can be avoided during rotation, thereby allowing the second wire clamp 22 to rotate smoothly.

[0067] Furthermore, a gripping clamp 23 is disposed at one end of the first wire clamp 21 and the second wire clamp 22 away from the main body 1 , and an elastic pad 231 is disposed inside the gripping clamp 23 .

[0068] Optionally, the elastic pad 231 may be a rubber pad, a silicone pad, polyurethane, a polyester elastomer, etc.

[0069] It can be understood that the elastic pad 231 is provided inside the gripping clamp 23, so that the contact area and friction between the gripping clamp 23 and the wire can be increased when the gripping clamp 23 clamps the wire, so as to facilitate the fixation of the wire and prevent the wire from falling off, and at the same time provide a certain buffering effect for the wire to avoid excessive squeezing, damage to the wire, and affect the use of the wire.

[0070] Compared with the prior art, the spacer rod of the utility model has the following advantages:

[0071] 1. A spacer rod of the utility model comprises a main body and a wire clamp rotatably connected to the main body, the wire clamp comprises a first wire clamp and a second wire clamp rotatably connected thereto, the first wire clamp is provided with a receiving groove, a telescopic pin is provided in the receiving groove, a fixing groove is provided at one end of the second wire clamp close to the telescopic pin, a limiting baffle is provided at one end of the fixing groove away from the first wire clamp, when the second wire clamp is rotated relative to the first wire clamp until the fixing groove is connected to the receiving groove, the telescopic pin at least partially enters the fixing groove.

[0072] It can be understood that when the first wire clamp and the second wire clamp are in the open state, the limit baffle is in abutment with the telescopic pin, compressing the telescopic pin into the accommodating groove. When the second wire clamp is rotated to clamp the first wire clamp, the fixed groove is connected with the accommodating groove as the second wire clamp rotates. At this time, the limit baffle is also separated from the abutment with the telescopic pin, so that the telescopic pin extends in the direction of the fixed groove and partially enters the fixed groove. By cooperating with the current position of the limit baffle and the telescopic pin, the second wire clamp can be limited from rotating in a direction away from the first wire clamp, so that the first wire clamp and the second wire clamp remain in a clamped state.

[0073] 2. In the spacer bar of the utility model, a first connecting hole is provided on the main body, and a first wire clamp includes a first connecting portion, and a second connecting hole and a first connecting member are provided on the first connecting portion, and the first connecting hole and the second connecting hole are rotatably matched with the first connecting member. The first wire clamp is fixed to the main body through the hole-axis matching of the first connecting hole, the second connecting hole and the first connecting member, and is rotatably connected with the main body, so as to facilitate the adjustment of the angle of the wire clamp.

[0074] 3. A limiting hole is provided on the main body of the spacer rod of the utility model. The limiting hole is axially parallel to the first connecting hole. A limiting piece is provided on the first connecting part. When the limiting piece cooperates with the limiting hole, there is a movable gap in the limiting hole, so that the wire clamp can rotate within a preset range. The cooperation between the limiting hole and the limiting piece limits the rotation angle of the wire clamp relative to the main body to a certain extent, thereby avoiding a large rotation of the wire clamp that reduces the spacing effect on the wires.

[0075] 4. The telescopic latch in the spacer bar of the utility model comprises a telescopic rod and a latch block connected to each other, and the telescopic rod is provided with a limiting protrusion and an elastic member abutting against the limiting protrusion.

[0076] It can be understood that when the telescopic pin is supported by the limiting baffle and retracted in the accommodating groove, the limiting protrusion compresses the elastic member to deform as the telescopic pin contracts. When the limiting baffle no longer supports the telescopic pin, the elastic member is not compressed and returns to its original state to push the telescopic pin to extend outward into the fixed groove.

[0077] 5. The end of the pin block in the spacer bar of the utility model close to the fixed groove is an inclined surface. During the rotation of the second wire clamp, the limit baffle plate abuts against the telescopic pin along the inclined surface, so that the second wire clamp rotates smoothly and the telescopic pin is gradually retracted.

[0078] 6. The first wire clamp in the spacer rod of the utility model includes a second connecting part connected to the first connecting part, the second connecting part has a hollow chamber, the second wire clamp is partially accommodated in the hollow chamber, and a limiting boss is provided at one end of the hollow chamber close to the second wire clamp to limit the second wire clamp from rotating too close to the first wire clamp. When the telescopic pin cooperates with the fixed groove, the pin block and the limiting boss both limit the limiting baffle, so that the wire clamp maintains the current clamping state.

[0079] 7. In the spacer bar of the utility model, a rotation arc surface is provided on the end surface of the second wire clamp close to the limiting boss to prevent the corresponding end surface of the second wire clamp from colliding with the limiting boss during rotation, thereby preventing the rotation from being interrupted.

[0080] 8. The first wire clamp and the second wire clamp in the spacer rod of the utility model are both provided with a gripping clamp at one end away from the main body, and an elastic pad is provided inside the gripping clamp, which can increase the contact area and friction with the wire when clamping the wire, facilitate the fixation of the wire and prevent the wire from falling off, and at the same time provide a certain buffering effect on the wire to avoid excessive squeezing, damage to the wire, and affect the use of the wire.
