[0002] Guard rail refers to the inside of the rail on the track Steel rail not bearing the vertical load of the wheel. It plays a vital role in the railway system, mainly used for protecting track structure, guiding the wheel through the harmful space and preventing derailment accidents according to the different laying places. The guard rail at the turnout frog is laid on the inside of the steel rail opposite the harmful space of the frog, guiding the wheel through the harmful space to avoid hitting the tip of the frog, and the guard rail on the bridge can prevent the derailed vehicle from hitting the bridge or falling under the bridge; The guard rail is laid on the inside of the inner rail on the small radius curve, which can reduce the side wear of the outer rail;

[0003] In daily maintenance, the guard rail bolts on the guard rail need to be checked to determine whether they are loose, but the checking and tightening of the guard rail bolts face many challenges:

[0004] 1) Narrow space: due to the very narrow gap between the guard rail and the track, the traditional electric wrench cannot enter, limiting mechanized operation.

[0005] 2) Low efficiency of manual operation: At present, due to tool limitations, the maintenance of guard rail bolts mainly relies on manual use of wrenches for loosening and tightening operation, which is labor-intensive and inefficient, and is difficult to meet the maintenance needs of large-scale railway lines. At the same time, manual operation is easily affected by human factors, which may cause uneven tightening of the bolts and affect the stability of the guard rail.

[0006] 3) Safety hazards: manual operation has certain safety risks, especially in high-pressure or high-load working environments.

[0007] At present, some special tools have appeared on the market, such as long-handle wrenches, bent wrenches, etc., but these tools still have the following shortcomings:

[0008] 1) Poor adaptability: These tools can usually only be used for specific types of bolts or specific locations, and cannot meet the needs of all scenarios.

[0009] 2) Inconvenient operation: Although improved, it is still not convenient enough in actual operation, especially when the angle needs to be frequently changed.

[0010] 3) High cost: The price of special tools is usually high, increasing the maintenance cost.

[0011] Therefore, a guard rail bolt wrench is proposed to solve the existing problems. UTILITY MODEL CONTENTS
