Abstract
The utility model belongs to the technical field of wrenches and particularly discloses a wrench for mounting and demounting screws of a positioning pin of an on-load tap changer. The technical scheme is that the wrench comprises a casing pipe with a nut sleeve fixed at the top end, wherein a connection rod is arranged on the tail portion of the casing pipe, and a torsion rod perpendicular to the connection rod is arranged on the tail portion of the connection rod. During use, the connection rod and the casing pipe extend into a barrel, the nut sleeve is sleeved on a nut, and an operator grips the torsion rod with hands and twists the torsion rod hard to screw off or screw up the nut. Arms of the operator are located outside the barrel so that the arms cannot be hurt in operation, operation is convenient and work efficiency is greatly improved.
Description
Technical field
The utility model belongs to the spanner technical field, particularly a kind of screw wrench for dismounting of on-load voltage regulating switch alignment pin.
Background technology
In maintenance process that on-load tap-changer of transformer is changed oil, switch alignment pin screw is positioned at the bottom of bucket, and motor and other parts are on the top of screw, because bucket is dark especially, is difficult to operation with common instrument, does not have this type of specific purpose tool on the market again.The main at present stubborn alignment pin of two monkey spanners that adopts, in operating process, monkey wrench and nut skid easily and drop in the oil, and operating efficiency is extremely low, and the space is limited in the bucket, and in operation, staff's arm is easy to run into a barrel wall, causes arm to scratch.
The utility model content
The technical problem that the utility model solves just provides a kind of screw wrench for dismounting of on-load voltage regulating switch alignment pin of safe and convenient to use, high efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Comprise that the top is fixed with the sleeve pipe of ut socket, be provided with connecting rod, be provided with the torsion bar vertical with said connecting rod at the afterbody of said connecting rod at the afterbody of said sleeve pipe.
The screw wrench for dismounting of the on-load voltage regulating switch alignment pin that the utility model provided is compared with prior art and is had the following advantages: owing to comprise that the top is fixed with the sleeve pipe of ut socket, be provided with connecting rod at the afterbody of said sleeve pipe, be provided with the torsion bar vertical with said connecting rod at the afterbody of said connecting rod; During use, connecting rod and sleeve pipe are stretched in the bucket, be enclosed within on the nut with ut socket; The operator grasps torsion bar, firmly twists torsion bar, and nut is backed out or tightened; Operator's arm is positioned at outside the bucket, therefore, can not damage arm in operation; And more convenient to operate, operating efficiency improves greatly.
Description of drawings
Fig. 1 is the structural representation of the screw wrench for dismounting of the on-load voltage regulating switch alignment pin that the utility model provided.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the structure of the screw wrench for dismounting of the on-load voltage regulating switch alignment pin that the utility model provided is done further detailed description.
As shown in Figure 1, the screw wrench for dismounting of this on-load voltage regulating switch alignment pin comprises that the top is fixed with the sleeve pipe 2 of ut socket 1, is provided with connecting rod 3 at the afterbody of sleeve pipe 2, is provided with the torsion bar 4 vertical with connecting rod 3 at the afterbody of connecting rod 3.During use, connecting rod 3 and sleeve pipe 2 are stretched in the bucket, be enclosed within on the nut with ut socket 1; The operator grasps torsion bar 4, firmly twists torsion bar 4, and nut is backed out or tightened; Operator's arm is positioned at outside the bucket, therefore, can not damage arm in operation; And more convenient to operate, operating efficiency improves greatly.
The foregoing description is the explanation to the utility model; Therefore; The protection domain of the utility model not only is confined to the foregoing description, as long as structure is identical with the screw wrench for dismounting of the utility model on-load voltage regulating switch alignment pin, just drops on the scope of the utility model protection.
Claims (1)
