Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission equipment technology, specifically to a clamp device for spacers and a phase-to-phase spacer assembly. Background Technology
[0002] The composite phase spacer consists of a phase composite insulator and matching connecting hardware. It is installed between phase conductors to control the spacing between the two phase conductors. The spacer is connected to the conductor by clamping the conductor with a clamp.
[0003] Patent publication number "CN105207155A" discloses a transmission line spacer bar clamp connection structure without rigid collision, including a spacer bar connecting clamp. The spacer bar connecting clamp includes a connecting rod, a clamp, and a clamp cover plate. The connecting rod and the clamp are an integral structure. The clamp is located at the front end of the connecting rod. The front end of the clamp and the front end of the clamp cover plate are hinged through a clamp pivot. The clamp cover plate includes a clamp cover plate body and a limiting part. A limiting pin is provided at the second end of the transverse connecting part of the clamp. When the clamp cover plate body and the clamp clamp body form a closed state, the limiting pin is located outside the limiting part to form a blocking limit.
[0004] When using this connector clamp, the clamp cover must be opened at a height, the power cable placed between the clamp cover and the clamp, and the clamp cover closed. A limiting pin is then inserted at the second end to prevent the clamp cover from opening further, thus clamping the power cable between the clamp cover and the clamp. However, the insertion hole at the second end is located above the limiting part. When the limiting pin is inserted at a height, it is easy for the limiting pin to misalign with the insertion hole at the second end, causing the limiting pin to fall from a height. This is inconvenient to use, reduces work efficiency, and can lead to waste of the limiting pin if it cannot be retrieved. Summary of the Invention

The main body of the wire clamp is provided with a sliding groove, and a locking pin is slidably provided in the sliding groove. When the locking pin slides to one end of the sliding groove near the pressure cover, the locking pin abuts against the locking part when the pressure cover is closed, thereby restricting the pressure cover from rotating and opening. When the locking pin slides to the other end of the sliding groove, the locking pin separates from the locking part. The main body of the wire clamp is provided with an elastic element, and the two ends of the elastic element abut against the locking pin and the main body of the wire clamp, respectively.
[0006] Furthermore, the contact surface between the locking part and the locking pin is a wedge-shaped surface. When the locking pin abuts against the locking part under the thrust of the elastic element, the locking pin presses against the cover through the wedge-shaped surface.

[0008] Furthermore, the clamp body includes two ear plates spaced apart from each other, and the two ear plates are respectively provided with the sliding grooves, and the two ends of the locking pin are slidably disposed in the sliding grooves of the two ear plates.
[0009] Furthermore, the clamp body is provided with a guide post, and there is a clearance between the guide post and the locking pin to allow the locking pin to slide; the elastic element includes a spring, one end of which is sleeved on the guide post and abuts against the clamp body, and the other end abuts against the locking pin.
[0010] Furthermore, the guide post points to the middle of the locking pin, and the spring is sleeved on the guide post and abuts against the middle of the locking pin.
[0011] Furthermore, the spring is located on both axial sides of the locking pin and abuts against the locking pin.
[0012] Furthermore, both the pressure cap and the clamping part of the wire clamp body are provided with anti-slip blocks, and the two anti-slip blocks form the wire hole when the pressure cap and the wire clamp body are closed.
[0013] Furthermore, the two anti-slip blocks are provided with semi-circular holes on their opposing sides, and the two semi-circular holes form wire holes when the pressure cap and the wire clamp body are closed.
[0014] Furthermore, the anti-slip block is made of rubber.
[0015] Furthermore, the end of the clamp body is provided with a bolting assembly, which includes two spaced mounting plates that are fixed to the clamp body. The two mounting plates form a U-shaped structure with the end of the clamp body, and the two mounting plates are respectively provided with coaxial mounting holes for bolting through bolts.
[0016] Furthermore, anti-slip layers are provided on the opposing sides of the two mounting plates, and an installation gap is provided between the two anti-slip layers.
[0017] Furthermore, both ends of the clamp body are provided with bolting components, and the pressure cap is rotatably disposed on the clamp body between the two bolting components.
[0018] This utility model also provides a phase spacer assembly including an insulator, equalizing rings disposed at both ends of the insulator, and a clamp device provided by this utility model, wherein the clamp device is disposed at the end of the equalizing ring away from the insulator.
[0019] Furthermore, an adjustment assembly is provided between the wire clamp device and the equalizing ring. The adjustment assembly includes a first plate and a second plate. The first plate has multiple sets of adjustment holes spaced apart along its axial direction, and the second plate has multiple sets of positioning holes spaced apart along its axial direction. Each set of adjustment holes can be connected to any set of positioning holes.
[0020] Furthermore, the adjustment assembly includes two first plates and a second plate disposed between the two first plates; the multiple sets of adjustment holes on the two first plates are coaxial.
[0021] Furthermore, the end of the equalizing ring furthest from the insulator is provided with two wire clamp devices in sequence, and the two ends of one wire clamp device near the equalizing ring are provided with bolting components. The two wire clamp devices are bolted together by a connecting plate.
[0022] The beneficial effects of this utility model include: 1. The pressure cap is rotatably mounted on the clamp body to form a clamp structure. It clamps the power transmission line through the wire hole when closed. A locking pin is slidably mounted on the groove on the clamp body. When the locking pin slides to one end of the groove, it abuts against the locking part to prevent the pressure cap from rotating and opening. When it abuts against the other end, it separates from the locking part and the pressure cap can be opened. The locking pin is pushed to one end of the groove by the elastic element to abut against the locking part, which can realize the default locking state of the pressure cap. This clamp device can be assembled in the production workshop. When using the clamp device for high-altitude operations, the locking pin is moved to the other side of the groove to open the pressure cap. After the power transmission line and clamping part are inserted, the pressure cap is pressed down. Under the action of the elastic element, the locking pin moves automatically to abut against the locking part, preventing the pressure cap from rotating and opening. It is convenient to use. 2. The contact surface between the locking part and the locking pin is a wedge-shaped structure, which allows the locking pin to slide towards the pressure cover under the thrust of the elastic element and press down on the pressure cover to achieve a clamping effect. 3. Both the locking part and the locking pin are formed into a wedge-shaped surface through a chamfered structure, which is simple in structure and easy to manufacture. At the same time, it increases the contact surface and reduces the pressure on the contact surface, thus reducing wear and tear during use. 4. By setting two ear plates at intervals and corresponding sliding grooves, the two ends of the locking pin slide within the two sliding grooves, making the sliding more stable; 5. The guide post on the main body of the clamp can fix and guide the extension and retraction of the spring root to prevent the spring from deflecting to the side when compressed. There is a clearance between the guide post and the locking pin to allow the locking pin to slide and avoid interference with the locking pin. 6. The anti-slip block on the clamping part of the cover and the clamp body forms a wire hole when the cover and the clamp body are closed, which can clamp the power transmission line and prevent the clamp device from sliding along the length of the power transmission line after clamping. 7. The clamp body can be bolted to the connector of the spacer bar by means of the bolting assembly. The bolting assembly is simple. It forms a U-shaped structure with the end of the clamp body through two mounting plates. The two mounting plates are provided with coaxial mounting holes, which makes it easy to insert the connector into the U-shaped opening and then use bolts to realize the bolting. The ring bolting has higher connection strength. 8. The anti-slip layer on the opposite side of the two mounting plates allows the connector that abuts against the spacer bar to play a better fixing role. At the same time, the bottom of the U-shaped structure can abut against the connector to achieve a limiting role and prevent the connector from rotating around the bolt. 9. The bolting components at both ends of the clamp body facilitate the extension and bolting of more clamp devices to form four-split clamps, six-split clamps, and other clamp devices capable of holding multiple split wires, adapting to different application scenarios with different numbers of split wires. 10. Equalizing rings are installed at both ends of the insulator of the phase spacer assembly to avoid uneven voltage distribution on both sides. The insulator extends the distance between the transmission lines on both sides. The provided clamp device is set at the end of the two equalizing rings away from the insulator, which facilitates quick clamping of the transmission line and makes it convenient to use.
[0023] The present invention relates to a wire clamp device for spacers, which forms a wire clamp by rotating a pressure cap on the wire clamp body. A locking pin is slidably installed in a groove on the wire clamp body. An elastic element abuts and pushes the locking pin to slide to one end near the pressure cap and abuts against the locking part of the pressure cap, thereby pressing the pressure cap tightly closed. When the locking pin is moved to one end away from the pressure cap, the locking pin separates from the locking part, and the pressure cap can be rotated open to insert the wire. This avoids the problem of aligning the locking pin when inserting it at a height, is convenient to use, and has great promotional value. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0029] Example 1 The present invention relates to a spacer bar clamping device 10, which is used to clamp transmission lines on phase spacers. The pressure cap 2 is rotatably mounted on the clamp body 1 to form a clamp structure. It clamps the power transmission line through the wire hole 3 when closed. A locking pin 4 is slidably mounted on the sliding groove 121 on the clamp body 1. When the locking pin 4 slides to one end of the sliding groove 121, it abuts against the locking part 21 to restrict the pressure cap 2 from rotating and opening. When it abuts against the other end, it separates from the locking part 21 and the pressure cap 2 can be opened. The locking pin 4 is pushed by the elastic element 13 to move to one end of the sliding groove 121 to abut against the locking part 21, which can realize the default locked state of the pressure cap 2. The clamp device 10 can be assembled in the production workshop. When using the clamp device 10 for high-altitude operations, the locking pin 4 can be moved to the other side of the sliding groove 121 to open the pressure cap 2. After the power transmission line and clamping part are inserted, the pressure cap 2 is pressed down. Under the force of the elastic element 13, the locking pin 4 moves automatically to abut against the locking part 21, restricting the pressure cap 2 from rotating and opening. It is convenient to use.
[0030] A wire clamp device 10 for a spacer bar, specifically, as follows: Figure 1-6 As shown, the device includes a clamp body 1 and a pressure plate 2. One end of the clamp body 1 is used to connect a spacer bar. One end of the pressure plate 2 is rotatably mounted on the clamp body 1, so that the pressure plate 2 and the clamp body 1 form two clamping plates of the clamp. A wire hole 3 for clamping the wire when closed is provided between the pressure plate 2 and the clamp body 1. The other end of the pressure plate 2 is provided with a locking part 21. The clamp body 1 is provided with a sliding groove 121, which is located on one side of the locking part 21 of the pressure plate 2. A locking pin 4 is slidably provided in the sliding groove 121 along the length of the sliding groove 121. When the locking pin 4 is located near the end of the pressure plate 2 in the sliding groove 121, the locking pin 4 abuts against the locking part 21 when the pressure plate 2 is closed. 1. This restricts the opening of the pressure cap 2 by rotation; when the locking pin 4 slides to the other end of the slide groove 121, the locking pin 4 separates from the locking part 21; the wire clamp body 1 is provided with an elastic element 13, the two ends of the elastic element 13 abut against the locking pin 4 and the wire clamp body 1 respectively; the elastic element 13 is used to push the locking pin 4 to slide to the end of the slide groove 121 near the pressure cap 2 and abut against the locking part 21. When an external force is applied to slide the locking pin 4 in the opposite direction to compress the elastic element 13, when the locking pin 4 slides to the end of the slide groove 121 away from the pressure cap 2, the locking pin 4 separates from the locking part 21, at which time the pressure cap 2 can be opened and closed by rotation; the locking part 21 can be a plate-shaped, block-shaped or other structure.
[0031] In one implementation scheme, such as Figure 4-6 As shown, the contact surface between the locking part 21 and the locking pin 4 is a wedge-shaped surface 41. When the locking pin 4 abuts against the locking part 21 under the pushing force of the elastic member 13, it presses against the pressure cover 2 through the wedge-shaped surface 41. When the locking pin 4 slides towards the pressure cover 2 under the pushing force of the elastic member 13, it presses down on the pressure cover 2, achieving a pressing effect. The length of the locking part 21 and the slope of the wedge-shaped surface 41 can be adjusted according to the actual situation so that the locking part 21 will not loosen when it is abutted by the locking pin 4.
[0032] Since the contact surface between the locking part 21 and the locking pin 4 is a wedge-shaped surface 41, as shown in the figure... Figure 4-6 As shown, the bottom side of the locking part 21 near the locking pin 4 is chamfered to form a wedge-shaped surface 41; the top side of the locking part 21 near the locking pin 4 is also chamfered to form a wedge-shaped surface 41. Both the locking part 21 and the locking pin 4 form a wedge-shaped surface 41 through chamfering structures, which is simple in structure, easy to manufacture, and at the same time increases the contact surface and reduces the pressure on the contact surface, thus reducing wear and tear during use.
[0033] Among the optional solutions, such as Figure 2 As shown, the wire clamp body 1 includes two opposing ear plates 12, each with a corresponding groove 121. The locking pin 4 is slidably disposed within the grooves 121 of the two ear plates 12. Preferably, the grooves 121 are located on the opposite sides of the two ear plates 12 and do not penetrate the ear plates 12, meaning the depth of the grooves 121 is less than the thickness of the ear plates 12. The locking pin 4 slides against the bottom wall of the groove 121 of the ear plate 12, thus restricting the axial movement of the locking pin 4. By spaced apart and correspondingly provided with grooves 121 on the two ear plates 12, the sliding of the locking pin 4 within the two grooves 121 provides greater stability.
[0034] Preferably, such as Figure 2 As shown, the locking pin 4 is provided with limiting members on both sides to restrict the axial movement of the locking pin 4 from sliding out of the slide groove 121. The limiting members can be limiting baffles or nuts that are screwed onto the locking pin 4. When the two slide grooves 121 are blind hole type slide grooves 121 (closed at one end), the limiting member is the bottom wall of the slide groove 121.
[0035] Preferably, such as Figure 5-6 As shown, the clamp body 1 is provided with a guide post 14, and a clearance is provided between the guide post 14 and the locking pin 4 to allow the locking pin 4 to slide. The elastic element 13 includes a spring, one end of which is sleeved on the guide post 14 and abuts against the clamp body 1, and the other end abuts against the locking pin 4. The guide post 14 on the clamp body 1 can fix and guide the extension and retraction of the spring root to avoid lateral deviation when the spring is compressed. The clearance between the guide post 14 and the locking pin 4 allows the locking pin 4 to slide and avoids interference with the locking pin 4.
[0036] In a specific plan, such as Figure 1 As shown, the guide post 14 is located between the two ear plates 12; the guide post 14 points to the middle of the locking pin 4, and the spring is sleeved on the guide post 14 and abuts against the middle of the locking pin 4 to prevent the spring from generating a pushing force on one end of the locking pin 4, causing the locking pin 4 to deflect to the side.
[0037] In another preferred embodiment, the spring is located on both axial sides of the locking pin 4 and abuts against the locking pin 4; the guide post 14 is provided on the clamp body 1 and points to both ends of the locking pin 4.
[0038] In one scheme, such as Figure 1 As shown, both the pressure cap 2 and the clamping part of the wire clamp body 1 are provided with anti-slip blocks 11. When the pressure cap 2 and the wire clamp body 1 are closed, the two anti-slip blocks 11 form wire holes 3. The two anti-slip blocks 11 have semi-circular holes on their opposing sides, which also form wire holes 3 when the pressure cap 2 and the wire clamp body 1 are closed. Optionally, the anti-slip blocks 11 are made of rubber. By using the anti-slip blocks 11 on the clamping parts of the pressure cap 2 and the wire clamp body 1 to form wire holes 3 when the pressure cap 2 and the wire clamp body 1 are closed, the power transmission line can be clamped, preventing the wire clamp device 10 from sliding along the length of the power transmission line after clamping.
[0039] In some schemes, such as Figure 1-4 As shown, the end of the clamp body 1 is provided with a bolting assembly 5. The bolting assembly 5 includes two spaced mounting plates 51 that are fixed to the clamp body 1. The two mounting plates 51 form a U-shaped structure with the end of the clamp body 1, and the two mounting plates 51 are provided with corresponding coaxial mounting holes for bolting with bolts 53. The clamp body 1 is directly or indirectly bolted to the spacer bar through the bolting assembly 5 at the end. The bolting assembly 5 is simple. The two mounting plates 51 form a U-shaped structure with the end of the clamp body 1. The two mounting plates 51 are provided with corresponding coaxial mounting holes, which facilitates the insertion of connectors (such as connecting plates 9) into the U-shaped openings and then bolting with bolts 53. The circumferential bolting provides higher connection strength.
[0040] Based on the fact that the end of the clamp body 1 is provided with a bolting component 5, such as Figure 3-4 As shown, anti-slip layers 52 are provided on the opposing sides of the two mounting plates 51, and an installation gap is provided between the two anti-slip layers 52. Through the anti-slip layers 52 on the opposing sides of the two mounting plates 51, the connector that abuts against the spacer bar can play a better fixing role. At the same time, the U-shaped bottom end of the U-shaped structure can abut against the connector to achieve a limiting role and prevent the connector from rotating around the bolt 53.
[0041] Based on the fact that the end of the clamp body 1 is provided with a bolting component 5, such as Figure 4 As shown, both ends of the clamp body 1 are provided with bolting components 5, and the pressure cap 2 is rotatably mounted on the clamp body 1 between the two bolting components 5. Through the bolting components 5 at both ends of the clamp body 1, it is easy to extend and bolt more clamp devices 10 to form four-split clamps, six-split clamps, etc., which are capable of clamping multiple split wires and are suitable for different usage scenarios with different numbers of split wires.
[0042] In actual use, the clamp body 1 has a bolting assembly 5 at one end. The bolting assembly 5 includes two mounting plates 51 that are fixed to the end of the clamp body 1. The two mounting plates 51 form a U-shaped structure at the end of the clamp body 1, and coaxial mounting holes are provided on the two mounting plates 51. One end of the pressure cover 2 is hinged to the two clamping plates on the clamp body 1 to form a clamp, and the other end is a locking part 21. The clamping part of the pressure cover 2 and the clamp body 1 is provided with anti-slip blocks 11. When the pressure cover 2 and the clamp body 1 are closed, the two anti-slip blocks 11 form wire holes 3 for clamping the transmission line. The clamp body 1 has a groove 121 located on one side of the locking part 21, and a locking pin is provided in the groove 121. 4. The locking pin 4 is provided with limiting parts at both ends to prevent it from moving axially out of the slide groove 121. The clamp body 1 is provided with a guide post 14 located on the side of the locking pin 4 away from the pressure cover 2. There is a clearance gap between the end of the guide post 14 and the locking pin 4. One end of the spring is sleeved on the guide post 14 and the other end is compressed and abuts against the locking pin 4. The bottom of the side of the locking pin 4 near the pressure cover 2 and the top of the side of the locking part 21 near the locking pin 4 are both chamfered. The chamfered structure forms a wedge-shaped surface 41 that contacts the locking pin 4 and the locking part 21. Under the action of the spring, the locking pin 4 moves only one end of the slide groove 121 and abuts against the pressure cover 2 through the wedge-shaped surface 41, which can prevent the pressure cover 2 from loosening.
[0043] The spacer bar clamp device 10 of this utility model is formed by rotating the pressure cover 2 on the clamp body 1. The locking pin 4 is slidably installed in the sliding groove 121 on the clamp body 1. The elastic member 13 abuts and pushes the locking pin 4 to slide to one end close to the pressure cover 2 and abuts against the locking part 21 of the pressure cover 2, thereby pressing the pressure cover 2 tightly closed. When the locking pin 4 is moved to one end away from the pressure cover 2, the locking pin 4 separates from the locking part 21, and the pressure cover 2 can be rotated open to insert the wire. This avoids the problem of aligning the locking pin 4 when inserting it at a height. It is convenient to use and has great promotional value.
[0044] Example 2 Another aspect of this utility model provides an interphase spacer assembly, such as... Figure 7-9 As shown, the assembly includes an insulator 6, equalizing rings 7, and a clamping device 10 provided by this invention. The equalizing rings 7 are located at both ends of the insulator 6, and the clamping device 10 is installed at the end of the equalizing rings 7 furthest from the insulator 6, thus forming a two-split wire spacer assembly. The equalizing rings 7 at both ends of the insulator 6 prevent uneven voltage distribution on both sides, and the insulator 6 extends the distance between the two transmission lines. The clamping device 10, located at the end of the two equalizing rings 7 furthest from the insulator 6, facilitates quick clamping of the transmission lines, making it convenient to use.
[0045] To facilitate adjustment of the length of the phase spacer assembly to suit transmission lines with different spacings, such as... Figure 7-8As shown, an adjustment component 8 is provided between the wire clamp device 10 and the equalizing ring 7. The adjustment component 8 includes a first plate 81 and a second plate 82. The first plate 81 is provided with multiple sets of adjustment holes 811 spaced apart along its axial direction, and the second plate 82 is provided with multiple sets of positioning holes 821 spaced apart along its axial direction. Each set of adjustment holes 811 can be connected to any set of positioning holes 821. Each set of positioning holes 821 can be connected to any set of adjustment holes 811. The number of holes in each set of positioning holes 821 is the same as the number of holes in each set of adjustment holes 811, with at least one hole and preferably two holes, which can achieve a fixed anti-rotation function and adjust the overall length of the adjustment component 8.
[0046] Preferably, such as Figure 8 As shown, the adjustment assembly 8 includes two first plates 81 and a second plate 82 disposed between the two first plates 81; multiple sets of adjustment holes 811 on the two first plates 81 are coaxial. The two first plates 81 clamp the second plate 82, which can improve the strength of the adjustment assembly 8.
[0047] It is worth noting that the end of the equalizing ring 7 away from the insulator 6 may be provided with multiple clamp devices 10 in sequence, so that the interphase spacer assembly can form a spacer assembly with multiple split clamps, such as a four-split clamp or a six-split clamp, which is suitable for maintaining the fixed spacing of multiple split wires.
[0048] like Figure 9 As shown, two wire clamp devices 10 are arranged in sequence at the end of the equalizing ring 7 away from the insulator 6. The two ends of one wire clamp device 10 near the equalizing ring 7 are provided with bolting components 5. The two wire clamp devices 10 are bolted together by a connecting plate 9. The end of the connecting plate 9 is inserted into the U-shaped opening of the wire clamp body 1 and abuts against the bottom of the U. The bolt 53 passes through the two mounting plates 51 and the connecting plate 9 and then screws a nut. When bolted, the connecting plate 9 can be placed to rotate around the bolt 53.
[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
