Description

Live working probe rod wrench

technical field

The utility model relates to an electrical safety appliance, in particular to a probe rod wrench for live work. the

Background technique

A large number of pin insulators are installed in the distribution line. During the long-term operation, due to the vibration caused by various reasons, the nuts at the fixed parts of the insulators are easy to loosen, causing the wires to fall off. Due to the short distance between the insulator and the live parts, live fastening cannot be carried out, and power failure fastening will affect the reliability of power supply. Therefore, there is an urgent need for a special tool that can perform flexible and convenient live tightening operations on loose nuts outside a safe distance (at least 70mm), and can ensure the personal safety of the staff and improve the reliability of power supply. the

Contents of the invention

The utility model provides a probe wrench for live work to solve the technical problem of lack of long-distance operation tools when fastening the fixing nuts of the current distribution line insulators. the

The utility model is realized by adopting the following technical scheme: a probe wrench for live work, comprising a first probe rod made of insulating material, the top of the first probe rod is connected with a wrench for fastening nuts through threads; The end of the first probe rod is threaded to a first sleeve, and the lower end of the first sleeve is threaded to a second probe rod made of insulating material; the movable sleeve on the second probe rod is provided with a first Two sleeves, a booster handle perpendicular to the axis of the sleeve is provided on the second sleeve; a hole is opened on the side wall of the second sleeve, and a top wire is provided in the hole; a limit plate is provided at the end of the second probe rod; The length of the first probe rod is 120 mm, the length of the first sleeve is 20 mm, and the length of the second probe rod is 120 mm; the length of the wrench is 12 mm. the

When in use, the operator climbs to a distance of more than 1.5 meters from the fastening insulator nut, extends the wrench at the top of the probe upward to lock the insulator nut, adjusts the position of the second sleeve up and down, and tightens the second sleeve through the top wire. It is fixed on the surface of the second probe rod, and then the booster handle on the second sleeve can be turned to tighten the nut; the length of the first probe rod and the second probe rod can effectively ensure the absolute safety of the operator; the top screw The fixing and loosening of the second sleeve can be realized, and the structure is light; the power-assisted handle is conducive to exerting force, which reduces the labor intensity of the operator, and can flexibly adjust the position according to the actual working situation, which is convenient for operation; the first probe rod and the second The two probe rods are threadedly connected through the first sleeve, which can be easily disassembled and assembled to meet the requirements of carrying, storage and transportation. The limit plate limits the second sleeve to prevent it from slipping. the

The utility model can fasten the bolts of the insulator outside the safe distance, ensures the safety of the operators, effectively reduces maintenance power outages, and improves the reliability of power supply; the whole device has simple structure, easy operation, low production cost and high reliability. the

Detailed ways

A probe rod wrench for live work, comprising a first probe rod 1 made of insulating material, the top of the first probe rod 1 is threadedly connected with a wrench 2 for fastening nuts; the end of the first probe rod 1 A first sleeve 3 is threaded, and the lower end of the first sleeve 3 is threaded with a second probe rod 4 made of insulating material; the second probe rod 4 is movable sleeved with a second sleeve 5. A booster handle 6 perpendicular to the axis of the sleeve is provided on the second sleeve 5; a hole is opened on the side wall of the second sleeve 5, and a top screw 7 is arranged in the hole; a limiter is provided at the end of the second probe rod 4 Bit plate 8; the length b of the first probe rod 1 is 120mm, the length c of the first sleeve is 20mm, and the length d of the second probe rod 4 is 120mm; the length a of the wrench 2 is 12mm; the diameter of the wrench 2 is 20~ 22mm (20mm, 21mm, 22mm). The lengths of the above-mentioned probe rods are the lengths exposed after the actual connection, and the part nested in the sleeve at the connection position is not included in the calculation. the

Both the first probe rod 1 and the second probe rod 4 are made of nylon material. Nylon material has good insulation performance and is light in texture, making it easier to use. the

The surface of the second probe rod 4 is provided with a plurality of positioning holes matched with the top wire 7 along the vertical direction. The top wire 7 can be inserted into the positioning hole to fix the second sleeve 5, which is more secure. the

The wrench 2 is cylindrical, and its structure matches the insulator nut 9. The wrench 2 is set on the outside of the nut to block the nut 9, and then the wrench is turned, and the nut 9 can be tightened. the

Fig. 1 is a schematic structural diagram of the utility model, Fig. 2 is a schematic structural diagram of the utility model marked with dimensions, and Fig. 3 is a schematic diagram of an operator 10 working, the operator 10 is located on the electric pole, and holds 11 pairs of live working probe wrenches The insulator nut 9 is tightened, and the top of the head is outside the safety distance e (the distance from the insulator is greater than or equal to 70mm). Since the head of the person is at the top when working, the sum of the lengths of the first and second probe rods should be far greater than the safety distance to ensure the absolute safety of the operator; at the same time, the length of the two probe rods should not be too long to avoid Inconvenient to use and unstable when turning. The two sleeves can also be made of insulating material. the
