Example (b):
referring to fig. 1 to 8, the system for loading and unloading containers 17 in an aligned row synchronously with horizontal fork type containers in the preferred embodiment of the present invention aims to realize the synchronous loading of a plurality of containers 17 on each loading flat plate of a transport train 9 or the synchronous unloading of a plurality of containers 17 on the transport train 9, thereby improving the efficiency of loading and unloading containers 17 in an aligned row. In order to achieve the above object, in the preferred embodiment of the present invention, a plurality of synchronous loading and unloading units are sequentially provided along the loading and unloading line 8 of the transport train 9 corresponding to each flat plate packed in the transport train 9, that is, the synchronous loading and unloading units are sequentially provided in the longitudinal direction of the loading and unloading line 8.
For the container synchronous handling system in the preferred embodiment of the present invention, the principle of operation can be broadly understood as follows:

The pre-storing work of each container 17 can be completed before the transport train 9 enters the station and stops, and when the transport train 9 enters the station and stops, each flat packing plate of the transport train 9 is vertically aligned with the corresponding container 17 respectively. And finally, controlling each synchronous loading and unloading unit to synchronously load each container 17 onto the corresponding container flat plate, so as to realize synchronous loading of containers on the whole train. The above process can be seen in FIGS. 4-8.
Of course, when the entire truck is required to be unloaded from the transport train 9, the control principle is just opposite to the above process: after the transport train 9 is stopped stably on the loading and unloading line 8, the synchronous loading and unloading units simultaneously start to operate, respectively match the containers 17 at the corresponding positions, and lift each container 17 for a certain distance, so that each container 17 is synchronously and quickly away from the train. The transport train 9 can be driven away from the loading and unloading line 8 without long-time stop, and after the transport train 9 is moved, the carrying trolley 20 can transfer the containers 17 to corresponding positions according to the storage or transfer requirements of the containers 17.
Specifically, the synchronized loading and unloading unit in the preferred embodiment is as shown in fig. 1-3, and is disposed in correspondence with the boxing platform of the transport train 9, i.e., one synchronized loading and unloading unit is disposed in correspondence with one boxing platform. Normally, a plurality of flat packing plates are continuously arranged on the transport train 9, that is, a plurality of synchronous loading and unloading units are sequentially arranged along the loading and unloading line 8. Meanwhile, a carrying trolley 20 is provided corresponding to the pre-storage and transfer of the container 17, and a carrying rail communicating with the loading and unloading line 8 is provided corresponding to the carrying trolley 20, so that the carrying trolley 20 can run on the carrying rail. Correspondingly, one end of the carrying track is connected to the loading and unloading line 8, and the other end extends to the warehouse for storing the containers 17, so that the carrying trolley 20 can travel back and forth between the loading and unloading line 8 and the warehouse.

Further, the tops of two adjacent pillars are correspondingly connected by the cross beam 10, so that a stable frame structure is formed. In the preferred embodiment the bottom of each post is fixed to the ground beside the loading and unloading line 8, although the bottom of each post may also be provided with running wheels for running and locking the carriage in the longitudinal direction of the loading and unloading line 8.
Further, a pair of translation trolleys, namely a first translation trolley 6 and a second translation trolley 11, are arranged at the bottom of the cross beam 10, are oppositely arranged in the transverse direction of the loading and unloading line 8 (namely, a vertical plane where a central connecting line of the two translation trolleys is located is perpendicular to the loading and unloading line 8), and can be synchronously driven to approach or depart from each other. Further, the axis of the dolly is parallel to the longitudinal direction of the loading and unloading line 8, and the central connecting line of each cross fork unit arranged below the same dolly is parallel to the longitudinal direction of the loading and unloading line 8. Meanwhile, two translation trolleys in the same synchronous loading and unloading unit are symmetrically arranged, and the cross units on two sides of the loading and unloading line 8 are symmetrically arranged on a vertical plane where the axis of the loading and unloading line 8 is located.
Preferably, a gray bus 7 is arranged above the translation trolleys, preferably arranged at the tops of the supports, antenna boxes 18 are respectively arranged at the tops of the two translation trolleys, the mobile positioning control of the translation trolleys can be realized through the electromagnetic induction of the gray bus 7 and the antenna boxes 18, the synchronous motion of the two translation trolleys is ensured, and the container rollover accident caused by the asynchronous motion of the left translation trolley and the right translation trolley is avoided. Further, the above-mentioned dolly is suspended at the bottom of the beam 10, and obviously, in practice, the dolly may be disposed above the beam 10 and may run back and forth on the top of the beam 10.
In practice, the container 17 is provided with loading and unloading slots corresponding to the loading and unloading thereof for the matching of the lifting and unloading mechanism, and in view of this, at least two cross-fork units are provided at intervals below the two dollies in a direction parallel to the loading and unloading line 8 for the matching and lifting of the two sides of the container 17. Taking the cross fork unit shown on the left side in fig. 1 as an example for description, the cross fork unit includes a first frame 5, a first lifting screw 4 and a first nut cross fork 3 correspondingly matched with the first lifting screw 4, and a first lifting motor 2 is arranged corresponding to the rotation of the first lifting screw 4.
Specifically, the first frame 5 is vertically arranged, the top of the first frame is fixed to the bottom of the first translation trolley 6, the first lifting screw rod 4 is vertically arranged on the first frame 5, external threads are formed in the periphery of the first lifting screw rod and matched with the first nut cross fork 3 to form a screw rod pair, and reciprocating lifting of the first nut cross fork 3 in the vertical direction can be achieved by rotating the first lifting screw rod 4. Meanwhile, a transverse fork is arranged on one side, opposite to the loading and unloading line 8, of the first nut transverse fork 3, one end of the transverse fork is fixed on a nut correspondingly matched with the first lifting screw rod 4, and the other end of the transverse fork points to one side of the loading and unloading line 8 and is used for being matched with a loading and unloading groove of the container 17. Further specifically, the first lifting motor 2 is disposed at the bottom of the first frame 5, and an output shaft of the first lifting motor is correspondingly matched with an end of the first lifting screw rod 4 through a coupler so as to drive the first lifting screw rod 4 to rotate forward or backward.
Further, the cross fork unit arranged at the bottom of the second translation trolley 11 in the preferred embodiment is preferably arranged symmetrically to the cross fork unit arranged at the bottom of the first translation trolley 6, and comprises a second frame 12, a second lifting screw 13, a second nut cross fork 14 and a second lifting motor 15 which are correspondingly and matchingly arranged. Meanwhile, in the preferred embodiment, the axes of the two translation trolleys are preferably parallel to the longitudinal direction of the loading and unloading line 8, and the two cross fork units at the bottom of the same translation trolley are respectively arranged at the two ends of the translation trolley and are symmetrically arranged. Of course, the cross-member units arranged at the bottom of the same dolly may also be arranged in a plurality, for example 3, 4 or more, side by side.
Further, the lifting motors of the cross fork units in the synchronous loading and unloading units are respectively and electrically connected with the synchronous joint control cable 19, so that the lifting motors in the cross fork units can move synchronously, the nut cross forks in the cross fork units are always on the same horizontal plane, and can be matched with or separated from the loading and unloading grooves of the container 17 at the same time. Meanwhile, each synchronous loading and unloading unit along the loading and unloading line 8 is electrically communicated through a synchronous joint control cable 19, and each synchronous loading and unloading unit is preferably connected into the synchronous joint control cable 19 in parallel, so that the synchronous movement of each synchronous loading and unloading unit can be controlled, and the independent control of each synchronous loading and unloading unit can be realized. Normally, the synchronous loading and unloading units operate synchronously to realize synchronous loading and unloading of a plurality of containers 17 on the entire train of transport trains 9.
The whole-column synchronous loading and unloading system of the suspended horizontal fork type container obtained through the arrangement preferably comprises a container loading process and a container unloading process.
When the containers 17 stacked in the warehouse need to be loaded in bulk to the transport train 9, i.e., a container loading process, the control process preferably includes:
(1) before the transport train 9 stops, the two translation trolleys in the synchronous loading and unloading unit at each position are respectively positioned at the position far away from the loading and unloading line 8, the carrying trolleys 20 are controlled to run on the carrying rails, the containers 17 in the warehouse are sequentially carried to the corresponding positions on the loading and unloading line 8, and the carrying trolleys 20 are locked.
And then controlling the synchronous loading and unloading unit at the position to start working, and firstly controlling the lifting motors to synchronously run so that the nut cross forks are positioned on the same horizontal plane, and the horizontal plane where the nut cross forks are positioned is coplanar with the loading and unloading grooves of the container 17 on the carrying trolley 20.
