Description

Technical Field

[0001] The utility model relates to a subway inspection identification code device, belonging to the technical field of intelligent transportation. Background Art

[0002] In daily subway operation, routine inspection of equipment status is a key step to ensure train safety and operation efficiency. These devices generally include, but are not limited to, track detection systems, fire protection facilities, signal devices, communication devices, power systems, and train control systems, etc. After long-term operation, subway equipment may experience aging and wear, and these problems may not be fully detected or predicted by the sensor system. Therefore, it is necessary for inspection personnel to regularly inspect the status of subway equipment.

[0003] Currently, the traditional subway inspection method is to paste two-dimensional codes on the areas or devices that need to be inspected. The inspection personnel confirm the location by scanning the two-dimensional codes, then upload photos of the area, and fill in the inspection date, personnel information, and maintenance content. However, this method of pasting two-dimensional codes has some defects. The surface of pipelines is usually circular or irregular, which makes it difficult for two-dimensional code labels to be firmly attached to these surfaces. Especially on old pipelines or pipelines with insulation layers, the labels are prone to falling off or curling, thus affecting their service life and stability. In addition, the pasted two-dimensional code labels may not be scanned due to environmental factors (such as humidity, corrosion, etc.) or physical damage, which may lead to inaccurate uploaded information, resulting in potential equipment failures or safety hazards not being discovered and handled in a timely manner, increasing the safety risks during subway operation.

[0004] Therefore, it is necessary to design a new subway inspection identification code device that can solve the problems existing in current subway inspections, such as difficult installation and fixation of labels in special environments, low durability of labels, and reduced service life, and can prevent two-dimensional codes from being damaged, so as to meet the requirements of subway inspection identification devices in terms of installability, durability, and accuracy. Summary of the Utility Model

[0005] Therefore, the purpose of the utility model is to provide a subway inspection identification code device that is easy to install and has high durability.

[0006] To achieve the above object, a subway inspection identification code device includes a lock nut, a fixed clamping cylinder, a fixed shaft, a connecting rope, and a two-dimensional code sign. The connecting rope connects the two-dimensional code sign and the fixed half shaft. At least two ropes are required for the connecting rope, and each rope is respectively connected to the two-dimensional code sign and the fixed half shaft. The fixed half shaft includes a left fixed half shaft and a right fixed half shaft. The two fixed half shafts are buckled with each other to form the fixed shaft, and the fixed shaft can be inserted into the fixed clamping cylinder. The fixed clamping cylinder includes two parts, an external thread part at the front end and a conical surface part at the rear end. A plurality of through grooves are formed on the conical surface part. The lock nut also includes two parts, an internal thread part at the front end and a pressing part at the rear end. The inner side surface of the pressing part is a conical surface matching the conical surface part.

[0007] The fixed clamping cylinder is provided with a key in the keyway; the fixed shaft is provided with a keyway.

[0008] The fixed shaft is provided with a necking part.

[0009] The left half shaft of the fixed shaft is provided with a tenon; the right half shaft of the fixed shaft is provided with a mortise.

[0010] The connecting rope has elasticity.

[0011] The connecting rope is multiple ropes.

[0012] The two-dimensional code sign is of a plastic-sealed structure.

[0013] Adopting the above technical solution, for the subway inspection identification code device of the present utility model, the lock nut and the fixed clamping cylinder are screwed to make the device stable and firm. Cooperating with the fixed shaft, the connecting rope can be tightened and loosened, which can adapt to various devices and is convenient for installation. In addition, the two-dimensional code identification sign is of a plastic-sealed structure, which not only has a smooth and clear surface, improving the success rate of scanning, but also is dust-proof, waterproof, and sun-proof, thus reducing the risk of being damaged, extending the service life, and improving the inspection efficiency.
