Description

Special combination spanner of narrow space in rigidity contact net high altitude

Technical Field

The utility model relates to a spanner, specific theory has related to a special combination spanner in narrow space in rigidity contact net high altitude.

Background

The rigid contact net is composed of an overhead rigid bus bar, a contact line, a supporting and positioning device, an insulating part, an overhead ground wire and the like, and although the rigid contact net is simple in structure and simple in operation and maintenance, various wrenches, especially the more critical 24# and 30# wrenches, need to be carried in the maintenance and repair process, and the risk of falling off at high altitude exists. In addition, in the process of maintenance operation, due to the narrow space, the wrench operation wastes time and labor, the replacement difficulty of repeated operation is large, and a suitable wrench product is difficult to find in the market.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims at the not enough of prior art to a spanner is provided.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a special combination spanner in narrow space in rigidity contact net high altitude, includes lateral part open-ended sleeve main part and long handle, the sleeve main part includes along axial polygon nut bayonet socket, one of them side opening of polygon nut bayonet socket forms the lateral part opening, the polygon nut bayonet socket uses axial direction's central point to divide for narrow mouthful bayonet socket end and wide mouthful bayonet socket end as the boundary, lateral part open-ended width respectively with the width of narrow mouthful bayonet socket end and wide mouthful bayonet socket end suits so that the card goes into the nut.

Basically, the long handle is fixed on the opposite side of the side opening of the sleeve main body.

Basically, the included angle between the long handle fixing position and the side opening position of the sleeve main body is less than 180 degrees.

Basically, the long handle fixed position with the contained angle of the lateral part opening position of sleeve main part is 90 degrees.

Basically, a longitudinal T-shaped groove along the axial direction is formed in the side wall of the sleeve main body, a T-shaped head is arranged at one end of the long handle, and the T-shaped head of the long handle is arranged in the longitudinal T-shaped groove.

Basically, the T-shaped groove extends from the middle position of the narrow-mouth bayonet end to the middle position of the wide-mouth bayonet end.

Basically, the lateral part of T-shaped groove sets up one row of locking screw, install pretension bolt in the locking screw.

Basically, the outer diameter of the sleeve main body corresponding to the narrow-mouth bayonet end is smaller than that of the wide-mouth bayonet end.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses utilize telescopic structure, increase the long handle outside the sleeve, solved the limited problem of high altitude construction operating range in the rigidity contact net, at sleeve one side opening, it is narrow to solve operating space, and the problem that normal sleeve can't get into replaces the spanner to the sleeve, and the spanner rigidity is not enough in solving the rigidity contact net, the problem of easy slippage.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1 and 2, a special combination spanner of narrow space in rigidity contact net high altitude, includes lateral part open-ended sleeve main part and long handle, the sleeve main part includes along axial polygon nut bayonet socket, one of them side opening of polygon nut bayonet socket forms the lateral part opening, the polygon nut bayonet socket uses axial direction's central point to divide into narrow mouthful bayonet socket end and wide mouthful bayonet socket end as the boundary, lateral part open-ended width respectively with the width of narrow mouthful bayonet socket end and wide mouthful bayonet socket end suits so that the card goes into the nut.

The long handle is fixed on the opposite side of the side opening of the sleeve main body.

In other embodiments, the angle between the long handle fixing position and the side opening position of the sleeve main body is less than 180 degrees, such as 90 degrees, so that the operation in a space with a special angle is convenient.

In other embodiments, in order to ensure the balance of the application force, the side wall of the sleeve main body is provided with a longitudinal T-shaped groove along the axial direction, one end of the long handle is provided with a T-shaped head, and the T-shaped head of the long handle is arranged in the longitudinal T-shaped groove. The T-shaped groove extends from the middle position of the narrow-mouth bayonet end to the middle position of the wide-mouth bayonet end. The lateral part of the T-shaped groove is provided with a row of locking screw holes, and pre-tightening bolts are installed in the locking screw holes. The problem of the stress of the sleeve is solved, because the length of the long handle is too long, if the force is exerted in the middle of the sleeve, the angle is possibly caused to be problematic because the acting end of the bolt is close to the lower part, the clamping is not firm, the operation is not good, under the condition that the height of the long handle is adjustable, the force application point is adjustable, and the stress of the sleeve is more accurate.

The outer diameter of the sleeve main body corresponding to the narrow-opening bayonet end is smaller than that of the wide-opening bayonet end, so that the structural strength of the sleeve is considered, and one end of the wide-opening bayonet of the sleeve is prevented from being damaged due to the thin wall.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
