Abstract

A special operating tool for electric power system, including an operating handle, the front end of which is a tool head connecting tenon, and the rear end is a handle. and handheld segment. There are two fixed sleeves on the body of the transition connecting section that can move axially to the hinged position respectively. The present invention designs a three-stage universal operating handle for operating tools often used in electrical equipment such as isolating switches and grounding switches. First of all, the connecting tenon of the tool head is a plug-in standard connector. Therefore, as long as the operating head matches the connecting head, it can be connected and used. Some special operating heads can also be integrated into the combination tool through customization. Secondly, under the action of the fixed sleeve, the operating handle can complete the mutual conversion of "Z-shaped", "L-shaped" and "one-shaped", and also has the functions of a rocker and a lever-type straight rod, thus solving the problem of traditional operating handles. There are many types, single form, inconvenient to carry and easy to carry by mistake.

Description

Power system special operating tools

【Technical field】

The invention belongs to a special operation tool for electric power system.

the

【technical background】

At present, the operating tools used in the power system are of various types and shapes. In particular, due to the large number of models of electrical equipment such as isolating switches and grounding switches, the operating tools mainly rely on the distribution of various manufacturers, causing operators to be at a loss for switching operations. Not strong, a little carelessness, mishandling tools, will affect the safe operation of electrical equipment.

the

【Content of invention】

In order to solve the above-mentioned technical problems, the present invention aims to provide a special operation tool for electric power system, relying on the operation tool, operators can better deal with equipment operations at key stations such as switching, so as to avoid affecting power equipment due to miscarriage of tools A phenomenon of safe operation occurs.

In order to achieve the above object, the present invention adopts the following technical solution: the special operating tool for electric power system includes an operating handle, the front end of the operating handle is a tool head connecting tenon, and the rear end is a handle. It is characterized in that: the operation The handle is composed of at least three sections of shafts that are movable and hinged, and the three sections of shafts are respectively a tool head connection section, a transition section and a hand-held section; Fixing sleeve for hinged parts.

As a preferred implementation, the two ends of the body of the transition connecting section are respectively provided with a stop marble.

As a preferred specific implementation, when the number of the transition connection sections is N sections, the number of the fixing sleeves is N+1.

the

Beneficial effects: Compared with the prior art, the present invention designs a three-stage general-purpose operating handle for operating tools frequently used in electrical equipment such as isolating switches and grounding switches. First of all, the connecting tenon of the tool head is a plug-in standard connector. Therefore, as long as the operating head matches the connecting head, it can be connected and used. Some special operating heads can also be integrated into the combination tool through customization. Secondly, under the action of the fixed sleeve, the operating handle can complete the mutual conversion of "Z-shaped", "L-shaped" and "one-shaped", and also has the functions of a rocker and a lever-type straight rod, thus solving the problem of traditional operating handles. There are many types, single form, inconvenient to carry and easy to carry by mistake.

【Description of drawings】

Fig. 1 is a schematic perspective view of an embodiment of the present invention.

FIG. 2 is a schematic structural diagram of the changing state in FIG. 1 .

In the figure: tool head connection section 1, tool head connection tenon 11, transition connection section 2, hinged part 21, hand-held section 3, hinged part 31, handle 4, pin shaft 5, pin shaft 6, fixed sleeve 7, fixed Sleeve 8, stop marble 9, stop marble 10.

【Detailed ways】

See Figure 1 and Figure 2. This operating handle is composed of three sections of movable hinged shafts, all of which are cylindrical, and are respectively a tool head connection section 1, a transition connection section 2 and a hand-held section 3. The shape of the tool head connection tenon 11 of the tool head connection section 1 is a common cube. On the body of the transition piece 2 there are two fastening sleeves 7 and 8 which can be moved axially to the articulation points 21 and 31 respectively. When the fixed sleeves 7 and 8 moved to the hinged parts 21 and 31 respectively, they were positioned by the stop marbles 9 and the stop marbles 10 respectively. At this moment, the operating handle was in a straight line. The stop pinball 9 and the stop pinball 10 are respectively installed in a radial through hole. The diameter of one end of the radial through hole is slightly smaller than the diameter of the stopper ball, and is positioned by a spring and a bolt. When only one fixed sleeve 7 or 8 was in the hinged position, the operating handle was in an "L" shape. When two fixed sleeves 7 and 8 were not at the hinged position, the operating handle was in the "Z" shape. According to needs, the number of transitional connection sections 2 can be appropriately increased. At this time, for each additional section of transitional connection section 2, a fixed sleeve is added at the same time, that is, when the number of transitional connection sections 2 is N sections, the fixed sleeve The number is N+1. One end of the hand-held section 3 is a hinged end (the structure of the two hinged parts 21 and 31 can adopt a concave-convex structure, which is hinged by the pin shaft 5 and the pin shaft 6), and the other end becomes the mandrel of the handle 4 after being extended, and the handle 4 It is a sleeve, which is movably positioned on the periphery of the mandrel by bolts, so that the handle 4 can rotate circumferentially around the mandrel to facilitate operation.

The above-mentioned embodiments are only used to explain the design concept of the present invention, and should not limit the concept of the present invention. All simple deformation structures inspired by the concept of the present invention should be regarded as falling within the scope of protection of the present invention.
