Description

A kind of city check-in baggage handling platform based on empty rail
Technical field
The utility model belongs to city check-in technical field, more particularly, to a kind of city check-in row based on empty rail Lee ships platform.
Background technique
With the development of economy, more persons select the tool that aircraft is gone on a journey as middle-long distance, check-in (check-in) ring Section is since check-in process is relatively complicated, and each link expends passenger's many times, so that passenger will spend largely on ground Time, it is often necessary to mention the first two hour arrival terminal, efficiently advantage is weakened by a degree of for air travel.City Check-in just refers to the process of that passenger directly handles check-in of setting out in urban district, it is airport and airline ground service Extend.Currently, each large and medium-sized urban track traffic in China is just gradually forming networking operation, while the route on city to airport is One essential route, major urban track traffic such as Kunming, Wuhan, Beijing gradually start the check-in system that plans a city The construction of system, i.e., offer check-in business is handled in advance in Rail Transit System (not only changes neck boarding card in advance, while being passenger Handle luggage and ship formality), make comfort, convenience and the rail traffic maximum revenue of passenger, but at present in addition to Hong Kong, state Precedent of the inner orbit transportation industry also without setting city check-in point.
At this stage, city check-in is based on subway mostly, and the entrucking needs of check-in luggage are accomplished to separate with passenger flows, So the other side for being generally selected at passenger getting on/off carries out luggage entrucking, the vehicle structure of city check-in is using common rail Road vehicular traffic structure.Platform structure is common platform in existing city check-in, is divided into station layer and station hall layer, passenger and row Lee is entered after station layer is waited by station hall layer and is entered in empty rail train, the side of the luggage handling goods of traditional platform structure limitation Formula, luggage, which is packed into compartment, need to pass through two steps, and luggage first need to rise to station layer by station hall layer by elevator or other modes, In addition to this, it also needs to be loaded and unloaded by laterally disposed car door.
Existing check-in subway concourse has the following defects, and passenger and luggage do not have subregion, will cause confusion;Luggage handling need elder generation Cargo is all transported to platform to stack, after be successively transported in compartment from existing car door, loading and unloading the low efficiency of goods, time-consuming;Separately On the one hand, since luggage entrucking is in the other side of passenger loading, it is therefore desirable to the platform of two sides, the big land occupation face of platform width be arranged Product is big, at high cost.
Utility model content
Aiming at the above defects or improvement requirements of the prior art, the utility model provides a kind of city check-in based on empty rail Baggage handling platform is connected among the station hall layer with station layer, in conjunction with the luggage top that station hall layer ground is arranged at empty rail train The vertical handling that device realizes luggage are stretched, the efficiency of luggage handling is improved, reduces the occupied area of platform.
To achieve the goals above, the utility model provides a kind of city check-in baggage handling platform based on empty rail, packet The station hall layer for the station layer of empty rail parking and set on the station layer bottom is included, the station layer bi-directional symmetrical is arranged, Middle part is equipped with the empty rail vehicle of round-trip two road, and two sides are equipped with platform, and the distance between described two sky rail vehicle roads are traffic safety Distance;
The middle part of the station hall layer is connected to the bottom of the two empty rails respectively, and on the ground at the middle part of the station hall layer It is equipped at intervals with check-in sales counter and luggage cargo gear, the length phase of the luggage cargo gear and sky rail vehicle compartment described in a section Matching, the luggage cargo gear include stretching device set on the luggage top of the underface of the empty rail and stretching dress set on luggage top The baggage transport tunnel in the outside set realizes the vertical handling of baggage container.
Further, the baggage transport tunnel is equipped with luggage traffic mechanism, and the luggage traffic mechanism includes along vehicle Device setting axial transport unit is stretched on the phloem-xylem transport unit of compartment length direction transport baggage container and closely the luggage top.
Further, the axial transport unit is equipped with several round rollers, the longitudinal direction with parallel in phloem-xylem transport unit Several round rollers in delivery unit are spaced setting, several round roller longitudinal directions spacing side by side in the axial transport unit laterally side by side Setting.
Further, the bottom of the axial transport unit is equipped with chain-linked conveyer, the mobile side of the chain-linked conveyer To identical as the moving direction of the longitudinally fed unit.
Further, luggage cargo gear, adjacent luggage load and unload goods at the length setting one in 2~4 section compartments Check-in sales counter is respectively provided between mechanism.
In general, it can obtain down the above technical solutions conceived by the present invention are compared with the prior art, Column the utility model has the advantages that
(1) city check-in baggage handling platform of the utility model based on empty rail, the empty rail among station hall layer and station layer It is connected at train, stretches the vertical handling that device realizes luggage in conjunction with the luggage top that station hall layer ground is arranged in, improve luggage dress The efficiency unloaded;Safety driving distance, safety driving distance is only arranged between two empty rail vehicle roads in the platform being simultaneously bi-directionally arranged symmetrically To guarantee that the empty rail train of travel in opposite directions two column mutually will not influence, it is not necessary that platform is in addition arranged between two empty rails, station is reduced The occupied area of platform.
(2) city check-in baggage handling platform of the utility model based on empty rail, luggage cargo gear and a section compartment Length match, and the luggage cargo gear at the length in 2~4 section compartments setting one, adjacent luggage load and unload cargo aircraft It is respectively provided with check-in sales counter between structure, handles check-in procedure, luggage cargo gear and the setting of check-in sales counter interval for passenger, will be worth Machine and luggage handling are provided separately, and are guaranteed the order of check-in, are improved the efficiency of check-in.
(3) city check-in baggage handling platform of the utility model based on empty rail, the luggage that luggage cargo gear includes Axial transport unit in transport channel and phloem-xylem transport unit cooperate, realize respectively luggage along compartment direction move and Baggage container is transported to luggage top to stretch on device, realizes the automation of handling;The chain-linked conveyer being equipped with simultaneously is used for The position of baggage container on axial transport unit is finely adjusted, it is made to stretch device completely to just with luggage top.
