  7. 7. A method of constructing a rapidly returnable passenger and cargo common subway car system according to claim 6, comprising the steps of: a foldable chair column device and a detachable central quick-release handrail column device are arranged in a train carriage; When the train carriage is converted from a passenger transport mode to a freight mode, the train carriage is converted into a seat freight state by pulling out a fixed pull ring on the seat, goods to be transported are loaded into a freight box, and the freight box is placed on the seat and fixed through the fixed pull ring; When the train carriage is converted from the passenger transport mode to the freight transport mode, the passenger seat of the folding seat post device and the handrail posts at the two ends of the seat are folded and locked together so as to increase freight transport capacity and freight transport area; When the train carriage is converted from the passenger transport mode to the freight transport mode, the central quick-dismantling handrail column device is quickly dismantled through the base fixed with the carriage floor and the telescopic handrail column matched with the base, so that the freight transport capacity and freight transport area are further increased.

Description

Passenger-cargo sharing subway carriage system capable of being rapidly prepared and construction method thereof Technical Field The invention relates to the technical field of subway freight devices, in particular to a passenger-cargo sharing subway carriage system capable of being quickly prepared and a construction method thereof. Background The freight traffic of rail transit is not a fresh concept, and at present, the operation mode of subway freight can be classified into 3 types, namely, a passenger-freight mixed loading mode claims to place small cargo hold units in passenger cabins, a car escort manually unloads the cargo holds during stop of a subway train, the original structure and the driving plan of the rail transit train are not changed, and the mode is easy to realize, low in manufacturing cost, low in transportation capacity and insignificant in scale economic effect. The collinear pulling and separating are required to update the layout of subway stations and the grouping and operation of trains, and logistics equipment is required to be equipped in the stations to carry out operations such as loading and unloading of cargo hold units of independent carriages, automatic sorting, middle-dedicated warehouse and the like. The collinear pulling mode adopts the mode of adding an extra freight carriage at the tail end of the train, so that passengers can get on and off and cargo loading and unloading can be completed synchronously. The collinearly separating mode adopts independent freight and passenger trains to operate in a collinearly shift mode, and separates the passenger and freight transportation by stopping at different platforms. However, the passenger-cargo mixed-loading subway freight mode of the conventional rail delivery system cannot form scale effect, and only small articles can be transported, and the collinear-pulling subway freight mode requires frequent grouping and unhooking operations of subway vehicles, so that the time consumption is long, and the collinear-pulling subway freight mode requires independent freight by providing logistics equipment in a station, so that the cost is high. Therefore, it is desirable to provide a passenger-cargo sharing subway car system that can be quickly serviced to achieve a quick conversion between passenger-freight cars, so as to reduce the influence of the co-linear trailing grouping and unhooking operations and increase the flexibility of subway transport capacity. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide a passenger-cargo sharing subway carriage system capable of being quickly prepared and a construction method thereof, which can quickly switch freight and passenger transport modes and realize quick conversion of passenger transport and freight transport carriages. In order to solve the problems, the technical scheme of the invention is as follows: A passenger and cargo sharing subway carriage system capable of being quickly prepared comprises a carriage, a folding chair column device and a central quick-release handrail column device, wherein the folding chair column device and the central quick-release handrail column device are arranged in the carriage, the folding chair column device comprises a passenger seat and handrail columns at two ends of the seat, the passenger seat and the handrail columns at two ends of the seat are folded or restored together when a passenger mode and a freight mode of a train carriage are mutually converted, the central quick-release handrail column device comprises a base fixed with the floor of the carriage and a telescopic handrail column matched with the base, and the central quick-release handrail column device is disassembled or restored when the passenger mode and the freight mode of the train carriage are mutually converted. Preferably, the seat of the folding seat post device can be rotated to the joint of the seat back through the rotating shaft of the folding seat, and the armrest posts on two sides of the seat can be lifted upwards along with the folding of the seat and locked by means of the train wall. Preferably, the seat folding includes unlocking the set screw by viewing the operating window, pulling out the folded seat and turning up to the locked position. Preferably, the folding of the seat armrest column comprises the steps that the upper armrest and the lower armrest of the seat armrest column are locked with a locking rod groove on the ceiling of a train through a locking rod, the locking rod is connected with the locking rod groove of the ceiling in a lifting and descending mode through a long rod with a concave connector, or reset, and in the folding process, the lower armrest column is connected with a folding seat armrest connecting rotating shaft, so that folding and locking can be completed together with the folding seat. Preferably, a telescopic locking mechanism for helping the cargo transferring box to lock is further ar
