Pulsars, as extreme celestial objects with exceptional physical properties, serve as vital tools for probing fundamental physics and astrophysical phenomena. The Nanshan 25 m Radio Telescope, a core facility of China’s Very Long Baseline Interferometry Network, possesses unique geographical and hardware advantages for pulsar observations, particularly in long-term timing monitoring and transient detection. Based on its long-term (2002–2009) timing data targeting 74 bright pulsars (δ >  −40°), the database and data retrieval environment compliant with the standards of a Virtual Observatory (VO) have been constructed in this work, which implements the functions of cone search and multi-object constraint search. The retrieval results can be transmitted to standard VO tools via the Simple Application Messaging Protocol for further data processing. For the archived pulsar data, the typical sampling rate during observations is 1 ms, and the duration of each observation is determined by the flux density of the pulsar in the corresponding observation band, generally ranging from 2 to 16 minutes. All data have undergone preprocessing using standard software packages including PSRchive and TEMPO, with the data format unified as PSRFITS and the file extension designated as .FTp. The database supports two access modes, namely web-based online retrieval and VO tool-based retrieval, facilitating flexible data access to meet diverse research requirements. As a valuable supplement to the global pulsar data resources, the dataset released in this work can be applied to carry out research on pulsar-related topics.
