Description

Socket wrench for insulated operating rod

technical field

The utility model relates to a live working tool for power transmission and transformation, in particular to a socket wrench for an insulating operating rod.

Background technique

The socket wrench consists of multiple sockets with hexagonal or twelve-pointed holes and is equipped with various accessories such as handles and extension rods. It is especially suitable for screwing bolts or nuts that are very narrow or deeply recessed. It is generally used for the nut end or the bolt end is completely lower than the surface to be connected, and the diameter of the concave hole cannot be used for an open-end wrench or adjustable wrench and a ring wrench, that is, a socket wrench can be used.

Due to the construction quality, running time, aging and other reasons of the current power transmission and transformation equipment, various kinds of clamp bolts loose frequently occur, especially the bolt loosening of the transmission line tension clamps, suspension clamps and other clamp hardware. It occurs frequently; during the peak summer period of electricity consumption, there will often be many over-temperature defects caused by bolt looseness in one day. important.

What needs to be pointed out in this case is that the existing tools are difficult to eliminate the defects through the ground potential operation method due to various defects, so the defect elimination work can only be carried out by the equipotential operation method, which further leads to the fact that the equipotential operation consumes a lot of personnel and The operation time is long, and it is difficult to adapt to the above-mentioned defect elimination work with many points and a wide range.

Therefore, in view of the above aspects, it is necessary to make reasonable improvements to the prior art.

Utility model content

In view of the above defects, the utility model provides a socket wrench for insulating operating rods that reduces labor intensity, improves work efficiency, reduces the number of operators on the rod, and can better deal with the characteristics of such defect-elimination work with multiple points and wide areas, so as to solve the current problems. There are many deficiencies in technology.

In order to achieve the above object, the utility model adopts the following technical solutions:

A socket wrench for an insulated operating rod, comprising a wrench body, the sleeve part of the wrench body is composed of two cylinders, the inner end of the wrench body is in contact with the inner stud of the connecting arm and the stud on the outer side of the connecting arm A nut is added at the other end; at the same time, a ratchet is provided in the inner cavity of the connecting arm and the teeth of the ratchet are in contact with the stud, and the tail of the connecting arm is connected to a section of the operating rod through a nail; the operating rod and the connecting arm are connected by It is composed of bar-shaped metal blocks, and each metal block is a hollow structure.

Correspondingly, the two ends of the metal block are respectively provided with screw holes for connecting with the connecting arm and the operating rod; a polygonal strip is added at the tail of the wrench body, and threads are left at the tail of the strip.

The beneficial effects of the socket wrench for the insulating operating rod described in the utility model are:

(1) By setting the socket wrench for the operating rod, the feasibility of live fastening the clamp bolts by means of ground potential operation is ensured, which not only reduces labor intensity, improves work efficiency, but also reduces the number of operators on the rod The quantity can better cope with the characteristics of this kind of defect elimination work with many points and a wide range;

(2) It is composed of two parts: the restructured socket wrench and the connecting arm used to connect with the operating rod. The combined design can use the same connecting arm to meet the needs of different types of nuts by designing socket wrenches of different sizes; the socket wrench The degree of loss will be far greater than that of the connecting arm, so the combined design also avoids the replacement of the whole set, and the hollow structure of the metal block reduces weight and increases economy;

(3) It is easy to adapt to the screw length of the bolt for installation. A polygonal strip is added at the end of the sleeve for connection with the connecting arm. There are enough threads at the end of the strip for fixing the nut.

detailed description

As shown in Figure 1-2, the socket wrench for the insulating operating rod according to the embodiment of the present invention includes a wrench body 1, and the inner end of the wrench body 1 is connected to the stud inside the connecting arm 6 and connected to the connecting arm 6. 6, a nut 3 is added on the outside; at the same time, a ratchet 4 is provided in the inner cavity of the connecting arm 6, and the tail of the connecting arm 6 is connected to a section of the operating rod 2 through a nail 5.

Correspondingly, the operating rod 2 and the connecting arm 6 are all made of bar-shaped metal blocks, each metal block is a hollow structure to reduce weight, and the two metal blocks are connected by piercing nails 5 to ensure their bending performance; the metal blocks Screw holes for connecting with the connecting arm 6 and the operating rod 2 are respectively provided at both ends.

The socket wrench for the insulated operating rod described in the above embodiments of the present invention is mainly composed of a reformed socket wrench and a connecting arm connected with the operating rod. Socket wrench to meet the needs of different types of nuts; the wear degree of the socket wrench will be far greater than that of the connecting arm, so the combined design also avoids the replacement of the whole set and increases the economy.

Similar to the ordinary socket wrench, but the copper pipe is deeper, so as to adapt to the length of the screw rod of the installed bolt; a polygonal strip is added at the end of the socket for connection with the connecting arm, and there is enough thread at the end of the strip for Install nuts to secure.

The socket wrench for the insulating operating rod described in the above embodiments of the present invention, when in use, the socket wrench is inserted into one end of the connecting arm, and is fixed by a nut. Corresponding to the polygonal hole, the socket wrench can be fastened and loosened by penetrating the connecting arm in different directions; the other end of the connecting arm of the combined socket wrench is connected with the tool connecting hole of the operating rod by a bolt; When the ground potential of the insulated operating rod is charged to tighten the clamp bolts, the operator holds one end of the operating rod, inserts the socket wrench into the bolt and nut to be tightened, pushes and pulls the operating rod, and achieves tightening and loosening by folding the connecting arm. The purpose of the nut.

The above description of the embodiments is for those of ordinary skill in the technical field to be able to understand and apply the technology of this case. Those skilled in the art can easily make various modifications to these examples, and apply the general principles described here to other embodiments without creative effort. Therefore, this case is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of this case should be within the scope of protection of this case.
