Description

Steel rail joint is dismouting spanner for bolt

Technical Field

The utility model relates to the technical field of steel rails, in particular to a dismounting wrench for a steel rail joint bolt.

Background

The steel rail is one section, the steel rail is continuous when in use, the steel rail needs to be connected, a fishplate, a joint bolt and the like need to be used, the fishplate (rail joint clamping plate) is commonly called a rail clamping plate and plays a role in connection at a rail joint, the fishplate is a connecting fastener for connecting and using between a rail and a rail, the joint bolt adopts more square-head bolts, in the connection process, the square-head bolts are fastened and inserted to be important, so that a screw rod part of the square-head bolts needs to be fixed at one end, nuts are locked or loosened at one end, the square-head bolts are usually fixed through a common spanner, as the fishplate is provided with a concave chute, the distance between the square-head end surface of the square-head bolts and the end surface of the fishplate is small, the contact area of the spanner is small, the spanner is easy to fall off in the specific locking or nut dismounting process, in addition, as the square-head gap between the handle and the square-head bolts is large, the square head bolt is easy to rotate along with the action of locking or disassembling the nut, so that the disassembly and the assembly are not in place, and based on the defects and the shortcomings, the prior art is necessarily improved, and the disassembly and assembly spanner for the steel rail joint bolt is designed.

SUMMERY OF THE UTILITY MODEL

The utility model mainly solves the technical problem of providing the dismounting wrench for the steel rail joint bolt, which has simple structure and ingenious design, can firmly fix the bolt in the assembling and disassembling processes, avoids the falling of the wrench or the rotation of the bolt and ensures the dismounting effect.

In order to solve the technical problems, the utility model adopts a technical scheme that: the dismounting wrench for the steel rail joint bolt comprises a handle rod, a first wrench head and a second wrench head, wherein the first wrench head and the second wrench head are respectively inserted into two ends of the handle rod; and a half hexagonal wrench opening is formed in the head of the second wrench.

Preferably, the outer side surface of the connecting convex block is arc-shaped, and the connecting convex block can rotate 180 degrees in the rectangular sliding groove.

Preferably, the handle bar is of widened design, the handle bar being tubular.

Compared with the prior art, the utility model has the beneficial effects that:

the structure is simple, the design is ingenious, the bolt can be firmly fixed in the assembling and disassembling process, the spanner is prevented from falling off or the bolt is prevented from rotating, and the assembling and disassembling effect is ensured;

the wrench is multipurpose, and the head of the first wrench is used for dismounting and mounting bolts in steel rail connection; the head of the second wrench is used for locking the hexagonal nut at the other end.

Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and will thus define the scope of the utility model more clearly and clearly.

Referring to fig. 1 and 2, an embodiment of the present invention includes:

a steel rail joint bolt dismounting wrench comprises a handle rod 1, a first wrench head part 2 and a second wrench head part 3, wherein the first wrench head part 2 and the second wrench head part 3 are respectively inserted into two ends of the handle rod 1, a rectangular wrench opening 21 is formed in the first wrench head part 2, the rectangular wrench opening 21 is matched with the square head of a square head bolt, connecting lugs 22 which can be clamped in a rectangular sliding groove 00 on a fishplate are symmetrically arranged on two sides of the rectangular wrench opening 21, and opposite surfaces of the two connecting lugs 22 and the inner side surface of the rectangular wrench opening 21 are positioned on the same plane; and a half hexagonal wrench opening 31 is formed in the second wrench head 3.

The outer side surface of the connecting projection 22 is arc-shaped, and the connecting projection 22 can rotate 180 degrees in the rectangular sliding groove 00.

The handle rod 1 is designed to be widened, and the handle rod 1 is tubular.

When the disassembly and assembly wrench for the steel rail joint bolt works, the handle rod 1 of the disassembly and assembly wrench is held by a hand, the rectangular wrench opening 21 is clamped at the square head of the square head bolt, the connecting convex block 22 is inserted into the rectangular sliding groove 00 on the fishplate to ensure the contact surface of the wrench and the square head bolt, and the common wrench is held by the other hand to lock the nut on the screw rod of the square head bolt or loosen and disassemble the nut.

The dismounting wrench for the steel rail joint bolt is simple in structure and ingenious in design, the bolt can be firmly fixed in the assembling and disassembling processes, the wrench is prevented from falling off or the bolt is prevented from rotating, and the dismounting effect is guaranteed.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
