The invention relates to a lifting maintenance operating platform configured on a magnetic-suspension type track inspection car comprising a support frame and a lifting suspension pocket which are connected by a retractable structure and a pulley structure. The retractable mechanism of the lifting suspension pocket is sheathed in a lifting fixture of the support frame; a motor is mounted at the lower part of the support frame and is provided with a wire rope reel; the wire rope and a wire rope fixed ring are fixed by a pulley mounted on the upper part of the support frame; the wire rope fixedring and a fixed base fixed on the suspension pocket bottom plate are fixed by a pin shaft; under the synchronous rotary control of the motor, the wire rope reel receives and releases the wire rope so that the lifting suspension pocket can be lifted stably. The invention realizes the structural design of a lifting maintenance platform with the lifting height over 3m, improves the load capacity ofthe lifting maintenance platform in case of restricting the dead weight and realizes the stability and the safety of the lifting maintenance platform in the restricted minimum occupying space.
Description
technical field [0001] The invention relates to the technical field of auxiliary equipment for maglev transportation system engineering vehicles, in particular to a lifting and maintenance operation platform arranged on a maglev rail inspection vehicle. Background technique [0002] High-speed maglev transportation technology has formed a series of patent applications in my country: CN200580001016.3, CN200580001019.7, CN200580001037.5, CN200580001057.2, CN200580001058.7, CN200580001218.8, CN200720182647.6, etc. Knowing about this type of technology is no secret. [0003] A kind of engineering vehicle is needed in the high-speed maglev transportation system: a track inspection vehicle, which is used as a line track inspection before passenger trains run. The items to be inspected include whether there is any intrusion into the limit of vehicle operation, whether there are foreign objects (especially ferromagnetic metals) on the track, whether the long stator surface of the tr...
