Description

Technical Field

[0001] The utility model relates to the technical field of live working auxiliary tools, in particular to a lead fixing device for live working on a distribution network. Background Art

[0002] Live working on a distribution network is to ensure the normal power supply and continuous operation of the power grid. At the same time, it can repair and maintain the circuit under the condition of the power grid running. This kind of operation allows maintenance personnel to immediately handle the faults and problems in the power grid without affecting the power supply, ensuring the reliability and continuous operation of power equipment.

[0003] Application No. 202122986205.X discloses a lead fixing device for live working on a distribution network, including a fixed cylinder. The top of the fixed cylinder is symmetrically provided with a lead holder and a wire holder. The lead holder and the wire holder have the same structure. An installation plate is connected at the middle position of the fixed cylinder. Two anti-detachment components cooperating with the lead holder and the wire holder are respectively arranged at both ends of the installation plate. This lead fixing device for live working on a distribution network is convenient for rolling connection of the device with the wire and the lead by setting a fixed frame, a connecting shaft, an insulating roller and a roller groove, avoiding excessive wear of the device with the wire and the lead. The wire and the lead can be limited by setting a wire blocking groove, an installation plate, a handle, a limiting block, a second spring and a limiting groove, preventing the wire and the lead from detaching from the device. The lengths of the fixed cylinder and the second connecting rod can be adjusted by setting a height adjustment slot, a height adjustment block, a sliding groove and a first spring, expanding the application range of the device.

[0004] The above solution has deficiencies in use. When fixing the lead, it is necessary to hang the lead on the insulating roller by hand, which has a certain risk. Therefore, we propose a lead fixing device for live working on a distribution network to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lead fixing device for live working on a distribution network to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lead fixing device for live working on distribution networks, including a support plate, on which a clamping and fixing component is installed. The clamping and fixing component includes a through groove opened on the upper surface of the support plate. The inner wall of the through groove is slidably connected with two sliding plates. Each right side surface of the sliding plates is provided with a sliding hole. The inner walls of the two sliding holes are jointly slidably connected with a support rod. The left and right ends of the support rod and the upper surface of the support plate are jointly fixedly connected with two fixing plates. Two springs are sleeved on the outer surface of the support rod. One side surface of each sliding plate close to each other is fixedly connected with a clamping plate. A pushing component is installed above the support plate. The pushing component includes a U-shaped rod fixedly connected to the upper surface of the support plate. The outer surface of the U-shaped rod is rotatably connected with two L-shaped push rods.

[0008] In a further embodiment, a retaining ring is fixedly connected to the outer surface of the support rod, and the retaining ring is located between the two sliding plates.

[0009] In a further embodiment, each right side surface of the sliding plates is provided with a stabilizing hole. The inner walls of the two stabilizing holes are slidably connected with a stabilizing rod, and the top end of the stabilizing rod is connected to the bottom surface of the support plate.

[0010] In a further embodiment, one side surface of each clamping plate close to each other is fixedly connected with an anti-wear pad, and anti-slip lines are opened on one side surface of each anti-wear pad close to each other.

[0011] In a further embodiment, an insulating sleeve is sleeved on the outer part of the top end of each L-shaped push rod.

[0012] In a further embodiment, a suspension rod is fixedly connected to the left side surface of the support plate, and a suspension ring is fixedly connected to the bottom end of the suspension rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The device can push the clamping and fixing component to open through the arranged pushing component. When the pushing force applied by the pushing component to the clamping and fixing component is released, the clamping and fixing component will clamp the outside of the lead. In the whole process, the staff does not need to directly contact the lead, thus reducing the potential danger. Through the cooperation of the arranged suspension rod and suspension ring, it is convenient for the staff to connect with the wire.

[0015] Through the cooperation of the arranged U-shaped rod, L-shaped push rod, sliding plate, support rod, spring and clamping plate, the L-shaped push rod can be used to push the sliding plate to move. The sliding plate not only compresses the spring, but also drives the clamping plates to separate. Then the two clamping plates are placed outside the lead. When the pushing force applied by the L-shaped push rod to the sliding plate is released, the spring will push the sliding plate, and the clamping plates will approach each other and clamp the outside of the lead, thus forming the fixation of the lead, avoiding the contact between the staff and the lead, and improving the safety.

[0024] Please refer to Figures 1-5 , in the present invention, a lead fixing device for live working on distribution networks includes a support plate 1. A suspension rod 4 is fixedly connected to the left side surface of the support plate 1, and a suspension ring 5 is fixedly connected to the bottom end of the suspension rod 4. The suspension ring 5 is used to facilitate the connection between the staff and other wires.

[0025] A clamping and fixing assembly 2 is installed on the support plate 1. The clamping and fixing assembly 2 includes a through groove 201 opened on the upper surface of the support plate 1. Two sliding plates 202 are slidably connected to the inner wall of the through groove 201. A sliding hole 203 is opened on the right side surface of each sliding plate 202. A support rod 204 is slidably connected to the inner walls of the two sliding holes 203. The left and right ends of the support rod 204 and the upper surface of the support plate 1 are fixedly connected with two fixing plates 205. The fixing plates 205 can be used to support the support rod 204, thereby forming a suspension for the sliding plate 202.

[0026] Two springs 206 are sleeved on the outer surface of the support rod 204. Clamping plates 207 are fixedly connected to the side surfaces of the two sliding plates 202 close to each other. The elasticity of the springs 206 can push the sliding plates 202. The sliding plates 202 will then push the clamping plates 207 to approach. The clamping plates 207 can be clamped outside the lead wire to fix it.

[0027] Anti-abrasion pads 211 are fixedly connected to the side surfaces of the two clamping plates 207 close to each other. Anti-slip lines are opened on the side surfaces of the two anti-abrasion pads 211 close to each other. The provided anti-abrasion pads 211 can not only avoid abrasion to the outside of the lead wire, but also enhance the clamping stability of the clamping plates 207 on the lead wire by using the anti-slip lines on the surface of the anti-abrasion pads 211.

[0028] A retaining ring 208 is fixedly connected to the outer surface of the support rod 204. The retaining ring 208 is located between the two sliding plates 202. The provided retaining ring 208 can form a resistance to the sliding plates 202 to prevent the sliding plates 202 from sliding too far, and prevent the clamping plates 207 from applying too much extrusion force to the lead wire.

[0029] A stabilizing hole 209 is opened on the right side surface of each sliding plate 202. A stabilizing rod 210 is slidably connected to the inner walls of the two stabilizing holes 209. The top end of the stabilizing rod 210 is connected to the bottom surface of the support plate 1. The cooperation of the stabilizing hole 209 and the stabilizing rod 210 can stabilize the sliding plate 202 and ensure the smoothness of the sliding plate 202.

[0030] A pushing assembly 3 is installed above the support plate 1. The pushing assembly 3 includes a U-shaped rod 301 fixedly connected to the upper surface of the support plate 1. Two L-shaped push rods 302 are rotatably connected to the outer surface of the U-shaped rod 301. When the tops of the two L-shaped push rods 302 are held close, the bottoms of the L-shaped push rods 302 will push the sliding plates 202, and the two clamping plates 207 will move away. Then, the two clamping plates 207 are placed outside the lead wire, and the L-shaped push rods 302 are released. The clamping plates 207 will be clamped outside the lead wire to fix the lead wire, avoiding the contact between the staff and the lead wire and improving the safety.

[0031] An insulating sleeve 303 is sleeved outside the top end of each L-shaped push rod 302. The provided insulating sleeve 303 can provide secondary protection for the staff, avoiding contact between the staff's hands and the L-shaped push rod 302, and further improving safety.

[0032] The working principle of the present utility model is as follows: When it is necessary to fix the lead wire, just hold the two L-shaped push rods 302 tightly by hand. The tops of the two L-shaped push rods 302 will approach each other, and the bottoms of the two L-shaped push rods 302 will move away from each other and push the sliding plate 202. The sliding plate 202 will move on the support rod 204 and compress the spring 206. At the same time, the sliding plate 202 will drive the clamping plate 207 away. Then, place the two clamping plates 207 outside the lead wire, and then release the L-shaped push rod 302. The spring 206 will stretch and push the sliding plate 202. The sliding plate 202 will drive the two clamping plates 207 to move closer to each other, and the clamping plate 207 will clamp outside the lead wire to form a fixation of the lead wire, avoiding contact between the staff and the lead wire and reducing the risk.

[0033] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
