Technical Field
The utility model relates to a logistics storage loading and unloading technical field particularly, relates to a three flexible board-like loading and unloading platforms of taking of warehouse suitable for cold chain logistics warehouse, constant temperature warehouse or have special requirements to the leakproofness of warehouse door.
Background
The traditional interior platform handling system for warehouse cargo handling adopts a horizontally installed handling platform, the handling platform is arranged below a warehouse door, one end of the handling platform is arranged in the warehouse door and far away from one end of the warehouse door, and the other end of the handling platform extends outwards to expose the handling platform outside a warehouse, so that the handling platform can be smoothly erected on a carriage bottom plate of a transport vehicle at the warehouse door when in operation. Such conventional inner platform loading and unloading systems require a gap to be reserved between the civil work of the warehouse and the loading and unloading platform. However, when the loading and unloading platform with the same structure is used for a cold-chain logistics warehouse or a constant-temperature warehouse, the reserved gaps can form continuous cold and heat exchange inside and outside the warehouse, and the exposed loading and unloading platform forms a large cold bridge, so that great energy loss is caused.
In order to avoid unnecessary cold and heat exchange, consider all to set up whole loading platform in the warehouse, for the storage space that the minimize took, install indoor handling system and all adopt the upset to erect formula, promptly: the one end of loading platform is installed and is being close to storehouse door department and the vertical upwards extension setting of whole loading platform, and the back is opened to storehouse door when the operation, outwards overturn the loading platform to take on the carriage bottom plate of the transport vechicle of berthing at the warehouse gate can, then erect the gate department in the warehouse during not operation. But since the distance from the mounting point to the bed of the transport vehicle parked at the warehouse doorway during work increases compared to conventional structures, this increased distance is mainly due to two parts: one part is the distance from the lower part of the warehouse door to the installation point, and the other part is the thickness of a heat insulation structure which is made for preventing the indoor temperature from flowing away through a wall body during the construction of the cold-chain logistics warehouse or the constant-temperature warehouse. However, the structure of the turnover vertical loading and unloading system is arranged at the door of the warehouse and is positioned above the ground of the warehouse, so that the space of the operation area of the warehouse is still occupied; meanwhile, in order to ensure that the loading and unloading platform is horizontal to the ground during operation so as to facilitate the travelling of a transport trolley or a transport robot, a groove with a certain depth is required to be reserved at the door opening of the warehouse so as to accommodate the loading and unloading platform during operation, so that when the loading and unloading platform is folded and erected in the warehouse, a groove is reserved at the door opening, and thus the operation in the warehouse is influenced; moreover, the relatively long structure which can be overturned and moved is erected in the warehouse, and the potential safety hazard of collision and/or toppling also exists; if an additional independent protection is needed to reduce the potential safety hazard, the complexity of the operation is increased.

In addition, the same warehouse may need to dock freight refrigerated vehicles of different models according to different customer requirements. At present, the width difference of a box body between a large van vehicle and a small van vehicle of a common marine refrigeration van vehicle is up to 500 mm. If the width of the loading platform is adapted to the large van, the loading platform cannot be used for the small van; and if design loading platform with the standard of small-size van, because the loading and unloading of present goods is simultaneously through fork truck or robot realization semi-automatization even full automatization, this makes the flexible access board overlap joint of loading platform have a partial space in the carriage of large-scale boxcar both sides, and this can cause serious hourglass cold to cause energy loss to have the potential safety hazard simultaneously. In order to avoid energy loss as much as possible, the existing solution is to set a plurality of reserved foundation pits of different sizes and configure loading and unloading platforms of different sizes to meet the loading and unloading requirements of different vehicle types. However, for a cold-chain logistics warehouse or a constant-temperature warehouse, heat-proof energy conducting structures need to be arranged at each reserved foundation pit, so that the construction cost and the operation management cost are increased.
