Description

Technical Field

[0001] The invention belongs to the field of power grid maintenance, and in particular relates to a wire pulling device for power grid maintenance. Background Art

[0002] As the "aorta" of modern energy transmission, the power grid is constantly exposed to the elements and complex operating conditions. It is susceptible to external forces such as lightning strikes, icing, strong winds, and aging, leading to frequent failures such as line breakage. Such failures not only threaten the stability of power supply but can also cause regional blackouts. Therefore, regular maintenance and emergency repairs are crucial to ensuring the safe operation of the power grid. When a power grid line breaks, the traditional emergency repair process requires first pulling up and resetting the fallen cable, and then tensioning and connecting the lines on both sides of the break.

[0003] During this process, existing technologies face multiple challenges: first, the lifting operation mostly relies on manpower or simple pulley systems, which are complicated to operate; second, the position of the clamp needs to be frequently adjusted during the connection process, which is complicated and time-consuming, and it is difficult to meet the time requirements for emergency repairs.

[0004] Therefore, we propose a wire pulling device for network maintenance to solve the above problems. Summary of the Invention

[0005] In view of the problems in the existing technology that the pulling operation mostly relies on manpower or simple pulley sets, the operation is complicated, and the clamp position needs to be frequently adjusted during the connection process, the operation is complicated and time-consuming, and it is difficult to meet the time requirements of emergency repairs, the present invention provides a wire pulling device for power grid maintenance.

[0006] The solution adopted by the present invention to solve the technical problem is: a wire pulling device for power grid maintenance, comprising two guide rods, two sliding seats and two sets of connection units, wherein the connection units include a connecting beam and two sets of cable clamps for connecting power transmission lines, and the two sets of cable clamps are detachably mounted at both ends of the connecting beam; Through holes are respectively opened at both ends of the sliding seat, and a manual winch is fixedly installed at the bottom thereof, a cable is wound on the manual winch, and a cable fixing clamp is installed at the end of the cable; The two guide rods are respectively passed through the two through holes so that the sliding seat can slide along the guide rods. The two guide rods are fixedly installed between the two connecting beams.

[0007] Preferably, the interior of the connecting beam is hollow, and fixing nuts are respectively installed at both ends thereof.

[0008] Preferably, the cable clamp includes an adjusting nut, a connecting plate and an adjusting screw. A reserved hole is provided on the connecting plate, and a clamping block is fixedly connected to its side. One end of the adjusting screw is threadedly connected to the fixing nut, and the other end passes through the reserved hole and is fixedly connected to a U-shaped rod. The adjusting nut is threadedly connected to the adjusting screw and contacts the connecting plate to fix the transmission line between the clamping block and the U-shaped rod.

[0009] Preferably, the cable fixing clamp comprises two arc-shaped clamping plates, and the upper and lower arc-shaped clamping plates are connected by two bolts.

[0010] Preferably, the cross-section of the through hole is circular or rectangular, and the cross-section of the guide rod is circular or rectangular.

[0011] Preferably, it also includes an adjustment mechanism for adjusting the distance between the two sliding seats.

[0012] Preferably, the adjustment mechanism includes a connecting seat and a double-section threaded rod, the two sections of the threaded rod have opposite directions, and bearing seats are respectively installed at the optical axes at both ends. The bearing seats are fixedly installed on the top of the connecting beam, and the connecting seat is fixedly installed on the top of the sliding seat. A connecting nut is fixedly installed inside it, and the connecting nut is threadedly connected to the double-section threaded rod.

[0013] Preferably, a rotating disk is fixedly mounted on one end of the double-section threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a manual winch, cable, and cable clamp combination at the bottom of the sliding seat to replace the complex operation of traditional manpower or simple pulleys to pull the cable. The operator only needs to turn the manual winch to quickly pull and restore the fallen cable, greatly reducing manpower input and operating difficulty. It is particularly suitable for time-sensitive operations in emergency repair scenarios.

[0015] 2. The present invention drives the double-section threaded rod to rotate through a rotating disk, synchronously and accurately adjusting the distance between the two sliding seats. Then, under the pulling action of the manual winch, the cables on both sides are pulled closer to each other, making it easier for power workers to reconnect broken lines.

[0016] 3. The present invention connects the two sets of connection units to the other two lines respectively, and cleverly uses the other two intact lines as natural support, eliminating the trouble of building additional support structures. The installation and fixation of the device can be completed quickly, improving work efficiency, and greatly enhancing the stability of the device during the cable pulling process, preventing the device from overturning, and ensuring the smooth progress of the pulling operation.

[0017] 4. The present invention uses the coordinated design of the adjusting nut, adjusting screw, U-shaped rod and clamping block. Operators can conveniently adjust the distance between the U-shaped rod and the clamping block by screwing the adjusting nut, thereby achieving rapid clamping and fixation of the transmission line and ensuring the stability of the connecting beam during use.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and examples.

[0021] See also Figure 1-2 The present invention provides a technical solution for a wire pulling device for power grid maintenance: Example 1: according to Figure 1 and Figure 2 As shown, it includes two guide rods 22, two sliding seats 25 and two sets of connection units. The connection unit includes a connecting beam 1 and two sets of cable clamps for connecting power lines. The interior of the connecting beam 1 is hollow, and fixing nuts 33 are installed at both ends.

[0022] Two sets of cable clamps are detachably installed at both ends of the connecting beam 1. By connecting the two sets of connection units to the other two lines respectively, the other two intact lines are cleverly used as natural supports, eliminating the trouble of building additional support structures. The installation and fixation of the device can be completed quickly, which improves the working efficiency and greatly enhances the stability of the device during the cable pulling process, preventing the device from overturning and ensuring the smooth progress of the pulling operation.

[0023] The cable clamp includes an adjusting nut 34, a connecting plate 35 and an adjusting screw 36. A reserved hole is provided on the connecting plate 35, and a clamping block 31 is fixedly connected to its side. One end of the adjusting screw 36 is threadedly connected to the fixing nut 33, and the other end thereof passes through the reserved hole and is fixedly connected to the U-shaped rod 32. By rotating the adjusting screw 36, the position of the U-shaped rod 32 can be adjusted so that the U-shaped rod 32 contacts the intact line. The adjusting nut 34 is threadedly connected to the adjusting screw 36 and contacts the connecting plate 35, fixing the transmission line between the clamping block 31 and the U-shaped rod 32 to ensure the stability of the connecting beam 1 during use.

[0024] Through holes are respectively provided at both ends of the sliding seat 25, and a manual winch 4 is fixedly installed at the bottom thereof. A cable is wound on the manual winch 4, and a cable fixing clamp 5 is installed at the end of the cable. The cable fixing clamp 5 includes two arc-shaped splints, and the upper and lower arc-shaped splints are connected by two bolts. The manual winch 4 and the cable and the cable fixing clamp 5 at the bottom of the sliding seat 25 are combined to replace the complicated operation of pulling the cable by traditional manpower or a simple pulley group. The operator only needs to turn the manual winch 4 to quickly pull and reset the fallen cable, which greatly reduces the manpower input and operation difficulty. It is especially suitable for the time-sensitive operation requirements in emergency repair scenarios.

[0025] The two guide rods 22 pass through the two through holes respectively, so that the sliding seat 25 can slide along the guide rods 22. The two guide rods 22 are fixedly installed between the two connecting beams 1.

[0026] It also includes an adjustment mechanism for adjusting the distance between the two sliding seats 25. The adjustment mechanism includes a connecting seat 24 and a double-section threaded rod 21. The two sections of the thread of the double-section threaded rod 21 are in opposite directions. Bearing seats 27 are respectively installed at the optical axes at both ends. The bearing seat 27 is fixedly installed on the top of the connecting beam 1. The connecting seat 24 is fixedly installed on the top of the sliding seat 25. A connecting nut 26 is fixedly installed therein. The connecting nut 26 is threadedly connected to the double-section threaded rod 21. A rotating disk 23 is fixedly installed at one end of the double-section threaded rod 21. The double-section threaded rod 21 is driven to rotate by the rotating disk 23 to synchronously and accurately adjust the distance between the two sliding seats 25. Then, under the pulling action of the manual winch 4, the cables on both sides are pulled closer to each other, so that the power workers can reconnect the broken lines.

[0027] In specific use, the present invention is a wire pulling device for power grid maintenance. First, two intact high-voltage wires are selected as connecting lines. Then, the cable clamps of the two sets of connecting units are respectively connected to the other two intact lines, and the device is installed and fixed. Then use the two arc-shaped clamps of the cable clamp 5 to clamp one end of the broken wire that has fallen to the ground, and use bolts to connect and fix it. Then turn the crank of the manual winch 4 to reel in the cable at a constant speed, driving the broken wire to be pulled up and reset. After the two broken wires are pulled back to their original positions, the rotary disk 23 is operated to drive the double-section threaded rod 21 to rotate, thereby synchronously and accurately adjusting the distance between the two sliding seats 25. Then, under the pulling action of the manual winch 4, the cables on both sides are pulled closer to each other. After the broken wires on both sides are pulled to the appropriate position, the line connection operation is carried out. After the repair is finally completed, the device is removed from the line for next use.

[0028] Example 2: Based on the first embodiment, the differences are as follows: the cross section of the through hole is circular or rectangular, and the cross section of the guide rod 22 is circular or rectangular.
