Description

Live working probe rod labor-saving wrench

technical field

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

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, it is impossible to carry out live fastening. In the case of erection of high and low voltage on the same pole, the staff need to cross the live low voltage line to fasten. The safety risk is relatively large, and the power failure will affect the reliability of power supply ; It is difficult for the remote operator to exert force, and the nut cannot be tightened. Therefore, there is an urgent need for a special tool that can tighten the loose nut with live electricity that is less labor-saving beyond a safe distance (at least 190mm) and improve the reliability of power supply.

Contents of the invention

The utility model provides a labor-saving wrench for a probe rod for live work to solve the technical problem of lack of long-distance operation tools when the fixing nuts of insulators of distribution lines are fastened.

The utility model is realized by adopting the following technical scheme: a probe rod labor-saving 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 end of the second probe rod is provided with a ratchet wrench ; The output shaft of the ratchet wrench is parallel to the axis of the second probe rod and connected to the end of the second probe rod; the length of the first probe rod is 120mm, the length of the first sleeve is 20mm, and the length of the second probe rod is 120mm ; The length of the wrench is 12mm.

When in use, the operator climbs to a distance of more than 1.9 meters from the tightening insulator nut, extends the wrench at the top of the probe rod upward to lock the insulator nut, and then can turn the ratchet wrench at the lower end of the second probe rod 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 ratchet wrench is a labor-saving tool, which reduces the labor intensity of the operator and is easy to operate; the first probe rod and the second probe rod pass through The threaded connection of the first sleeve can be easily disassembled and assembled to meet the requirements of carrying, storing and transporting.

The utility model can fasten the bolts of the insulator outside the safe distance, which ensures the safety of the operators, effectively reduces maintenance power outages, greatly reduces labor intensity, and improves the reliability of power supply; the whole device is simple in structure, easy to operate and easy to produce Low cost and high reliability.

Detailed ways

A probe rod labor-saving wrench for live work, comprising a first probe rod 1 made of insulating material, the top of the first probe rod 1 is threaded with a wrench 2 for fastening nuts; the first probe rod 1 The end is threadedly connected with a first sleeve 3, and the lower end of the first sleeve 3 is threaded with a second probe rod 4 made of insulating material; the end of the second probe rod 4 is provided with a ratchet wrench 5; The output shaft of the ratchet wrench 5 is parallel to the axis of the second probe rod and connected to the end of the second probe rod 4; the length b of the first probe rod 1 is 120mm, the length c of the first sleeve is 20mm, and the length c of the second probe rod The length d of the rod 4 is 120 mm; the length a of the wrench 2 is 12 mm; the diameter of the wrench 2 is 22 mm. 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.

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 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 6, and then the wrench is turned, and the nut 6 can be tightened.

Described ratchet wrench 5 is the product that can be purchased on the market, and its output shaft is connected with the lower end of the second probe rod 4, and the lower end of the second probe rod 4 is made into a structure that matches the output shaft of the ratchet wrench 5, both Fixed connection.

Fig. 1 is the structure schematic diagram of the present utility model, and the plane where whole ratchet wrench 5 is located is perpendicular to the second probe rod 4; Fig. 2 is the utility model structure schematic diagram marked with dimensions, and Fig. 3 is the schematic diagram of the operation personnel 7 when working, the operation The person 7 is located on the iron tower, holding the live working probe rod labor-saving wrench 8 to tighten the insulator nut 6, and the head is outside the safety distance e (the distance from the low-voltage line 9 is greater than or equal to 70mm); the distance f between the low-voltage line 9 and the insulator is 1.2m . 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.
