Description

Technical Field

[0001] The invention relates to the technical field of electric power fittings, in particular to a lead clamp for electric power installation. Background Art

[0002] Power installation refers to the process of installing, debugging and testing various power equipment, cables, lines, etc. in accordance with the prescribed standards and requirements based on the needs and design of the power system. Power installation is not only related to the transmission and distribution of electric energy, but also directly affects the stability and safety of the power system. Among them, overhead lines are one of the main modes of power transmission, and their installation and maintenance are particularly critical. Overhead lines transmit electricity from power plants to users through towers, conductors, insulators and other components. Its advantages are low cost, fast construction speed, and easy maintenance. However, overhead lines also face challenges from the natural environment, such as wind vibration, snow pressure, lightning, etc.

[0003] As the key hardware for connecting the conductor and the tower, the wedge-shaped tension clamp has a unique design. It uses the tension of the stranded wire to lock the stranded wire in the clamp, effectively preventing the wire from loosening or falling off due to vibration. In addition, especially on the insulators of the corner or terminal tension towers, its arc-shaped structure can match the bending shape of the conductor, thereby reducing the stress concentration and wear caused by shape mismatch. At the same time, the wedge-shaped tension clamp also has the characteristics of corrosion resistance and wear resistance, and can adapt to various complex climate and environmental conditions to ensure the stability and safety of overhead lines.

[0004] However, the existing wedge-shaped tension clamps on the market are differentiated by size. Wires of different specifications require wire clamps of specified specifications and models to fix the wires, and their applicability is limited to a certain extent. In addition, when the wires are subjected to large tension and external environmental forces (such as wind), the working principle of traditional wedge-shaped tension clamps is that when the wires are subjected to external forces, these wedges will move and radially press the wires, thereby ensuring close contact and a firm connection between the wires and the clamps to prevent detachment. However, when the external environmental forces calm down, the wedges in the wedge-shaped tension clamps usually have self-locking properties, which means that once the wedges move and press the wires, they will form a locked state, making it difficult for the wedges to be pushed back to their original position by external forces, so that long-term high-intensity compression may cause fatigue of the wire material, especially near the clamping position, which may reduce the overall strength and durability of the wire.

[0017] 2. When the conductor is subjected to external environmental forces, the arc-shaped bent plate will be pressed synchronously, so that the matching clamping plate can gradually rise through the cooperation of the extrusion block and the extrusion groove, and cooperate with the wedge block body, and simultaneously radially compress the surface of the conductor to disperse the compression force. When the external environmental forces are calm, the matching clamping plate can be driven back to its original position by the spring, ensuring that a low compression force can be maintained when no external forces are applied, avoiding fatigue and damage of the conductor due to long-term high-intensity compression, and helping to improve the stability and safety of the power lines.

[0018] 3. When the conductor is subjected to external environmental forces, when the arc-shaped bent plate moves, it can synchronously drive the fitting rod 2 to move, so that through the cooperation of the gear and the ratchet, the maximum clamping force of the matching splint can be maintained unchanged, avoiding the situation that when the conductor is shaken by wind, the squeezing force of the arc-shaped bent plate changes continuously, causing the matching splint to repeat the clamping and loosening steps, resulting in unnecessary wear and fatigue on the conductor, thereby enhancing the stability of the use of the clamp.

[0021] 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.

[0022] For example, see Figure 1-Figure 9 The present invention provides a lead clamp for power installation, including a wire clamp body 1, a wedge-shaped slide groove 2 is provided at the middle position of the outside of the wire clamp body 1, a wedge block body 3 is movably installed inside the wedge-shaped slide groove 2, and an arc-shaped bent plate 4 is provided on the front inner wall of the wedge-shaped slide groove 2.

[0023] A cavity 5 is formed on the lower inner wall of the wedge-shaped slide groove 2 , and a support plate 6 is slidably connected to the inner wall of the cavity 5 .

[0024] A wire adapting component 7 is disposed on the top of the supporting plate 6 .

[0025] Further, the wire adapter component 7 includes an adjustment seat 701, and the outer wall of the adjustment seat 701 fits and slides with the inner wall of the cavity 5, the top of the adjustment seat 701 is an arc surface, and a movable groove 1 702 is opened on the top of the adjustment seat 701, the inner wall of the movable groove 1 702 is adapted to be slidably connected with a matching clamping plate 703, and the inner wall of the movable groove 1 702 is penetrated with a movable groove 2 704, and the lower surface of the matching clamping plate 703 is fixedly connected with a connecting plate 705 at an equal distance, and the outer wall of the connecting plate 705 is fixedly connected with the inner wall of the cavity 5. The inner walls of the movable groove 2 704 fit together and slide, the bottom of the adjustment seat 701 is rotatably connected with a screw rod 706, and the top of the support plate 6 is provided with a movable groove 3 707 corresponding to the screw rod 706. The bottom of the screw rod 706 passes through the interior of the wire clamp body 1 and extends to the outside of the wire clamp body 1, and the bottom of the screw rod 706 is fixedly connected with a handle 708. The outer wall of the screw rod 706 is threadedly connected to the interior of the wire clamp body 1, and a fitting rod 10 is equidistantly arranged on one side wall of the support plate 6 facing the arc-shaped bent plate 4.

[0026] In this embodiment, when installing wires of different specifications, the wires are first passed through the wedge-shaped slide grooves 2 of the wire clamp body 1 , and then the wires and the wedge body 3 are fixed to each other through the clamping blocks of the wedge body 3 .

[0027] Then, a cavity 5 is opened through the lower inner wall of the wedge-shaped slide groove 2, and the outer wall of the adjustment seat 701 slides in contact with the inner wall of the cavity 5, and the bottom of the adjustment seat 701 is rotatably connected to a screw 706, and at the same time, the bottom of the screw 706 passes through the interior of the wire clamp body 1 and extends to the outside of the wire clamp body 1, and the bottom of the screw 706 is fixedly connected to a handle 708, so that the adjustment seat 701 can be restricted by the cavity 5, so that when the handle 708 is rotated, the adjustment seat 701 can be synchronously driven to move up and down.

[0028] Then, the top of the adjustment seat 701 is curved, and a movable groove 702 is opened on the top of the adjustment seat 701, and the inner wall of the movable groove 702 is adapted to be slidably connected with a matching clamp 703, so that the adjustment seat 701 can be used to drive the matching clamp 703 to move synchronously. At this time, the matching clamp 703 and the wedge block body 3 can cooperate with each other to clamp wires of different specifications.

[0029] Furthermore, since the diameter of the wire directly determines its rigidity and the degree of deformation when subjected to force, the bending curvature of the wire with a small diameter can be larger, while the bending curvature of the wire with a large diameter is smaller. Therefore, in order to ensure that the surface of the arc-shaped bent plate 4 can fit and contact with the surfaces of wires of different diameters, a fitting rod 10 is arranged at an equal distance from the support plate 6 toward one side wall of the arc-shaped bent plate 4, and the fitting rod 10 forms a telescopic structure with the support plate 6 through a spring 802, and the other end of the fitting rod 10 is fitted to the side wall of the support plate 6 through a spring 802, and at the same time, a shaft rod 713 is fixedly connected to the interior of the arc-shaped bent plate 4, and the two ends of the shaft rod 713 are rotatably connected to the inner wall of the wedge-shaped slide 2, and the shaft rod 713 is The outer walls of the two ends of 13 are fitted with return springs 714, and one end of the return spring 714 is overlapped on the outer wall of the shaft rod 713, and the other end of the return spring 714 is overlapped on the inner wall of the wedge-shaped slide groove 2. Under normal circumstances, the return spring 714 is used to drive the arc bending plate 4, so that the other end of the fitting rod 10 is fitted to the side wall of the support plate 6 through the spring 802. When the clamping plate 703 is raised to clamp the wire with a small diameter, the fitting rod 10 will be driven to rise synchronously at this time, and the linear rise of the fitting rod 10 will cause the arc bending plate 4 to rotate clockwise, which will make the bending curvature smaller and not match the wire with a small diameter. Therefore, through the inner wall of the movable groove 702 A movable groove 2 704 is provided through it, and a connecting plate 705 is fixedly connected to the lower surface of the matching clamping plate 703 at an equal distance, and the outer wall of the connecting plate 705 fits and slides with the inner wall of the movable groove 2 704, and at the same time, a movable groove 3 707 is provided through the top of the support plate 6 corresponding to the screw 706, and a support rod 709 is fixedly connected to the top of the support plate 6 at an equal distance, and a limiting groove 1 710 is provided at the bottom of the adjustment seat 701 corresponding to the support rod 709, and at the same time, the top of the support rod 709 is T-shaped, and the top of the support rod 709 fits and slides with the inner wall of the limiting groove 1 710, and the outer wall of the support plate 6 away from the arc-shaped bent plate 4 is hinged with a pull rod 712, and the other end of the pull rod 712 is hinged to the cavity 5. The inner wall, when the clamping plate 703 is rising, can synchronously drive the support plate 6 to rise through the cooperation of the support rod 709 and the limit groove 710. At this time, through the setting of the pull rod 712, the support plate 6 will synchronously slide in the direction away from the arc-shaped bent plate 4 when rising, so that the arc-shaped bent plate 4 rotates counterclockwise, so that the bending arc becomes larger, so that it can match the wire with a small diameter. Similarly, when the clamping plate 703 is lowered to clamp the wire with a large diameter, the bending arc will become smaller, thereby realizing the synchronous adjustment of the angle of the arc-shaped bent plate 4, so that the surface of the arc-shaped bent plate 4 can keep in contact with the wires of different specifications, thereby reducing the deformation and wear of the wires when they are subjected to force.

[0030] As described above, when installing wires of different specifications, the adjusting seat 701 can be driven to move up and down by rotating the handle 708, so that it can cooperate with the wedge block body 3 to clamp wires of different specifications. At the same time, since the diameter of the wire directly determines its rigidity and the degree of deformation when subjected to force, during the clamping process, the angle of the arc-shaped bent plate 4 can be synchronously adjusted through the cooperation of the pull rod 712 and the fitting rod 10, so that the surface of the arc-shaped bent plate 4 can be kept in contact with the wires of different specifications, reducing the deformation and wear of the wire when subjected to force, thereby extending the service life of the wire and the clamp.

[0031] Embodiment 2: Based on the above embodiment, a loosening pressing component 8 is provided on the top of the support plate 6 .

[0032] Furthermore, the clamping loose component 8 includes a spring 802, a groove 801 is provided at one end of the fitting rod 10 toward the support plate 6, and the inner wall of the groove 801 fits and slides with the upper and lower surfaces of the support plate 6, one end of the spring 802 is fixedly connected to the inner wall of the groove 801, and the other end of the spring 802 is fixedly connected to the outer wall of one side of the support plate 6, the end of the fitting rod 10 away from the arc-shaped bent plate 4 is fixedly connected to a sliding rod 803, and the bottom of the sliding rod 803 fits and slides with the upper surface of the support plate 6, the top of the sliding rod 803 is fixedly connected with an extrusion block 804 at an equal distance, and the upper surface of the extrusion block 804 is in an inclined shape, the bottom of the connecting plate 705 is provided with an extrusion groove 805 at an equal distance corresponding to the extrusion block 804, and the upper surface of the sliding rod 803 away from the fitting rod 10 is fixedly connected with gear teeth 806 at an equal distance.

[0033] In this embodiment, when the wire is subjected to external force from the environment, the wire will be tightened, so that the arc-shaped bent plate 4 that is in contact with it can be squeezed, so that the movement of the arc-shaped bent plate 4 can be used to drive the fitting rod 10 to move. At this time, a sliding rod 803 is fixedly connected to one end of the fitting rod 10 away from the arc-shaped bent plate 4, and the bottom of the sliding rod 803 slides in contact with the upper surface of the support plate 6, and an extrusion block 804 is fixedly connected to the top of the sliding rod 803 at an equal distance. At the same time, the upper surface of the extrusion block 804 is in an inclined shape, and an extrusion groove 805 is provided at an equal distance from the bottom of the connecting plate 705 corresponding to the extrusion block 804, so that the fitting rod 10 can be moved. The sliding bar 803 is driven to move, and then the multiple extrusion blocks 804 are driven to extrude the extrusion groove 805 of the connecting plate 705. At this time, the outer wall on one side close to the two support rods 709 is fixedly connected to the connecting plate 705 corresponding to the limiting rod 711, and the outer walls on both sides of the connecting plate 705 are fitted and slid with the outer walls on one side close to the two limiting rods 711. Therefore, under the restriction of the limiting rod 711, the cooperation between the extrusion block 804 and the extrusion groove 805 can be used to enable the connecting plate 705 to drive the matching clamping plate 703 to rise, and form a cooperation with the wedge block body 3 that is moving itself, and simultaneously radially compress the surface of the wire to disperse the clamping force.

[0034] At this time, when the external force in the environment is calm, the wire will no longer be affected by the external force in the environment, and the squeezing force applied to the arc-shaped bent plate 4 will become smaller. At this time, one end of the spring 802 is fixedly connected to the inner wall of the groove 801, and the other end of the spring 802 is fixedly connected to the outer wall of one side of the support plate 6, so that the spring 802 can drive the matching clamping plate 703 back to its original position, ensuring that a low clamping force can be maintained when no external force is applied, thereby avoiding fatigue and damage of the wire due to long-term high-intensity compression.

[0035] As described above, when the conductor is subjected to external environmental forces, the arc-shaped bent plate 4 will be simultaneously pressed and fitted, so that the cooperation between the extrusion block 804 and the extrusion groove 805 can make the matching clamping plate 703 gradually rise and cooperate with the wedge block body 3, and simultaneously radially compress the surface of the conductor to disperse the clamping force. When the external environmental forces are calm, the spring 802 can drive the matching clamping plate 703 to return to its original position, ensuring that a low clamping force can be maintained when no external forces are applied, thereby avoiding fatigue and damage of the conductor due to long-term high-intensity compression, and helping to improve the stability and safety of the power lines.

[0036] Embodiment 3: Based on the above embodiment, an auxiliary component 9 is provided on the top of the support plate 6 .

[0037] Furthermore, the auxiliary component 9 includes a second fitting rod 901, and a second groove 902 is provided on one end of the fitting rod 901 toward the support plate 6, and the inner wall of the second groove 902 fits and slides with the outer wall of the support plate 6, the inner wall of the second groove 902 is fixedly connected with a second spring 903, and the other end of the second spring 903 is fixedly connected to the outer wall of one side of the support plate 6, the end of the fitting rod 901 away from the arc-shaped bent plate 4 is fixedly connected with a second sliding rod 904, and the bottom of the second sliding rod 904 fits and slides with the upper surface of the support plate 6, the top of the support plate 6 is equidistantly fixedly connected with a mounting plate 905, a side wall where the two mounting plates 905 are close to each other is rotatably connected with a rotating rod 906, and the outer wall of the rotating rod 906 is equidistantly fixedly connected with a gear 907, the bottom side of the gear 907 is meshed and matched with the gear teeth 806, and the outer wall of the rotating rod 906 is fixedly connected with a ratchet 908.

[0038] In this embodiment, when the wire is subjected to a relatively strong external environmental force, the wire will continue to shake, so that the squeezing force on the arc-shaped bent plate 4 will continue to change, so that under the action of the spring 1 802, the matching clamping plate 703 will continuously repeat the steps of tightening and loosening, which may cause unnecessary wear and fatigue to the wire. Therefore, a groove 2 902 is opened through the fitting rod 2 901 toward one end of the support plate 6, and the inner wall of the groove 2 902 fits and slides with the outer wall of the support plate 6, and the inner wall of the groove 2 902 is fixedly connected to the spring 2 903, and the other end of the spring 2 903 is fixedly connected to the outer wall of one side of the support plate 6, and the end of the fitting rod 2 901 away from the arc-shaped bent plate 4 is fixedly connected to the sliding rod 2 904, and the sliding rod 2 90 The bottom of 4 fits and slides with the upper surface of the support plate 6, so that under normal circumstances, the fitting rod 10 and the fitting rod 2 901 will be synchronously fitted with the surface of the arc-shaped bent plate 4, that is, when the arc-shaped bent plate 4 squeezes the fitting rod 10, it will also squeeze the fitting rod 2 901. At this time, the mounting plate 905 is fixedly connected at an equal distance through the top of the support plate 6, and the side wall where the two mounting plates 905 are close to each other is rotatably connected to the rotating rod 906, and the outer wall of the rotating rod 906 is fixedly connected with a gear 907 at an equal distance, and the bottom side of the gear 907 is meshed and matched with the gear teeth 806, so that when the fitting rod 10 moves, the gear 907 will be driven to rotate through the gear teeth 806 on the sliding rod 1 803, and then the ratchet 908 will be synchronously driven to rotate.

[0039] At this time, when the fitting rod 901 moves, the top of the support plate 6 is fixedly connected to the fixing frame 909 at an equal distance corresponding to the sliding rod 904, and the end of the sliding rod 904 away from the arc-shaped bent plate 4 passes through the side wall of the fixing frame 909 and extends to the other side wall, and the top of the fixing frame 909 is penetrated by a limiting groove 910, and the inner wall of the limiting groove 910 is fitted and slidably connected with a top block 911, and the bottom of the top block 911 is fixedly connected with a slider 912 at an equal distance, and the outer walls of both sides of the sliding rod 904 are provided with movable grooves 913 corresponding to the slider 912, and the outer wall of the side where the two sliders 912 are close to the inner wall of the movable groove 913 The walls fit and slide together, and the outer wall of the side where the two sliding blocks 912 are close to each other is fixedly connected with a sliding column 914, and the inner wall of the movable groove four 913 is provided with a guiding straight groove 915 corresponding to the sliding column 914, and the inner wall of the movable groove four 913 is provided with a guiding inclined groove 916 corresponding to the sliding column 914, and the outer wall of the sliding column 914 fits and slides with the inner walls of the guiding straight groove 915 and the guiding inclined groove 916, so that the sliding rod 2 904 can be synchronously driven to pass through the inside of the fixed frame 909 and move. At this time, through the cooperation of the sliding column 914 with the guiding inclined groove 916 and the guiding straight groove 915, the top block 911 can be lifted up first and the lifting height of the top block 911 can be maintained.

[0040] At this time, a slot 917 is provided through the top of the top block 911, and the inner wall of the slot 917 is fixedly connected to a spring three 918, and the other end of the spring three 918 is fixedly connected to a block 919, and at the same time, the outer wall of the block 919 fits and slides with the inner wall of the slot 917, so that the block 919 can be inserted into the ratchet 908 by the rising of the top block 911, thereby limiting the sliding rod 803 and making it unable to retreat. When the external force of the environment is strong, when the connecting plate 705 is at the highest point, when the arc bent plate 4 swings, since the ratchet 908 cannot rotate, the maximum clamping force of the matching splint 703 can be maintained without changing. When the arc-shaped bent plate 4 returns to its initial position, the fitting rod 2 901 will follow back to the initial position, thereby driving the top block 911 to descend under the drive of the guiding inclined groove 916, thereby releasing the lock of the ratchet 908 and allowing the ratchet 908 to rotate. At this time, the slide bar 1 803 can return to its position only under the drive of the spring 1 802, thereby avoiding the repeated tightening and loosening steps of the matching splint 703, which causes unnecessary wear and fatigue to the wire. Furthermore, during the sliding process of the slide bar 1 803, the slide bar 1 803 will be restricted by a side wall close to the mounting plate 905 and the fixing frame 909, thereby ensuring the stability of the slide bar 1 803 during the sliding process.

[0041] As described above, when the conductor is subjected to external environmental forces, when the arc-shaped bent plate 4 moves, the fitting rod 901 can be driven to move synchronously, so that the maximum clamping force of the fitting splint 703 can be maintained unchanged through the cooperation of the gear teeth 806 and the ratchet 908, thereby avoiding that when the conductor is shaken by wind, the squeezing force on the arc-shaped bent plate 4 changes continuously, causing the fitting splint 703 to repeat the clamping and loosening steps, resulting in unnecessary wear and fatigue on the conductor, thereby enhancing the stability of the clamp.
