Example (b):

referring to fig. 1 to 9, the fixed lifting type container alignment synchronous loading and unloading system in the preferred embodiment of the present invention is designed to achieve synchronous loading of a plurality of containers 1 on each loading plate of a train 15 or synchronous unloading of a plurality of containers 1 on the train 15, thereby improving the loading and unloading efficiency of the containers 1. 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 train 15 at both sides of the loading and unloading line 8 corresponding to each loading plate of the train 15, that is, the synchronous loading and unloading units are 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:

when the containers need to be loaded on the train 15, the containers 1 to be loaded are sequentially carried to the corresponding synchronous loading and unloading units by the carrying trolleys 17 before the train 15 enters the station and stops, and the corresponding containers 1 are lifted by a certain height by the synchronous loading and unloading units at the corresponding positions. The pre-storing work of each container 1 can be completed before the train 15 enters the station and stops, and then the train 15 enters the station and stops, and each loading flat plate of the train 15 is vertically aligned with the corresponding container 1. And finally, controlling each synchronous loading and unloading unit to load the containers onto the corresponding loading flat plate simultaneously, and realizing synchronous loading of the containers on the whole train. The above process can be seen in FIGS. 5-9.

Of course, when the whole vehicle is unloaded from the train 15, the operation principle is just opposite to the above process, and after the train 15 is stopped stably on the loading and unloading line 8, each synchronous loading and unloading unit simultaneously starts to operate, respectively matches the containers 1 at the corresponding positions, and lifts each container 1 for a certain distance, so that each container 1 is synchronously and quickly away from the train. The train 15 can be driven away from the loading and unloading line 8 without long-time stop, and after the train 15 is moved, the carrying trolley 17 can transfer the containers 1 to corresponding positions according to the storage or transfer requirements of the containers 1.

Specifically, the synchronized loading and unloading unit in the preferred embodiment is shown in fig. 1-4, and is positioned in correspondence with the loading decks of the train 15, i.e., one synchronized loading and unloading unit is positioned in correspondence with one loading deck. Normally, a plurality of loading plates are continuously arranged on the train 15, that is, a plurality of synchronous loading and unloading units are arranged in sequence along the loading and unloading line 8. Meanwhile, a carrying trolley 17 is pre-stored corresponding to the container 1, and a carrying rail communicated with the loading and unloading line 8 is arranged corresponding to the carrying trolley 17, so that the carrying trolley 17 can run on the carrying rail. Correspondingly, one end of the carrying track is communicated with the loading and unloading line 8, and the other end of the carrying track extends to a warehouse for storing the container 1, so that the carrying trolley can run back and forth between the loading and unloading line 8 and the warehouse.

Further, at least one lifting mechanism is respectively arranged on two sides of the synchronous loading and unloading unit in the preferred embodiment, for example, in the preferred embodiment shown in fig. 4, the lifting mechanisms arranged on two sides of the loading and unloading line 8 are symmetrically arranged, and the number of the lifting mechanisms on two sides of the loading and unloading line 8 is two respectively. The lifting mechanism shown on the left side of fig. 1 is described as an example, and includes a first lifting rod 2, a first traverse cylinder 3, a first lifting rod 4, and a first lifting cylinder 5, which are correspondingly disposed in sequence. Wherein, first lifter 4 and first a lift section of thick bamboo 5 are vertical coaxial setting, and first lifter 4 sets up in the top of first a lift section of thick bamboo 5, and its bottom activity embedding is the first a lift section of thick bamboo 5 tops of tube-shape to can follow vertical reciprocal lift under the exogenic drive.

Further, the bottom of the first lifting cylinder 5 is fixedly arranged, and in a preferred embodiment, in order to ensure the relative position of the first lifting rod 4 and the container 1, a pit with a certain depth, namely a first pit 6, is arranged beside the loading and unloading line 8, and then the bottom of the first lifting cylinder 5 is fixed on the bottom surface of the first pit 6. In order to realize the vertical lifting of the first lifting rod 4 relative to the first lifting cylinder 5, in a preferred embodiment, a lifting component is arranged corresponding to the two, for example, a first hydraulic pump 7 arranged in the first pit 6, the first hydraulic pump 7 is correspondingly matched with the first lifting cylinder 5, and the vertical lifting of the first lifting rod 4 can be correspondingly realized by changing the hydraulic pressure in the first lifting cylinder 5. However, it is obvious that the above-mentioned lifting assembly is not the only form that the first lifting rod 4 can be driven to vertically lift, and when it is actually arranged, other forms of lifting assemblies, such as a gear-driven lifting assembly, a screw-driven lifting assembly, a pneumatic-driven lifting assembly, etc., can be arranged for the first lifting rod 4 and the first lifting cylinder 5 according to actual needs.

Further, a first traverse cylinder 3 is provided on the top of the first lift lever 4, the end of which is always aligned with one side of the loading/unloading line 8, and a first horizontally movable lifting lever 2 is provided on the first traverse cylinder 3. Specifically, the first traverse cylinder 3 is of a horizontal cylindrical structure, one end of the first lifting rod 2 is coaxially embedded at the end of the first traverse cylinder 3 and can reciprocate along an axis in the horizontal direction, and the first lifting rod 2 and the first traverse cylinder 3 are preferably in matched connection in a chain transmission, gear transmission or screw transmission mode, so that the horizontal movement distance can be freely controlled to be close to or far away from the container 1 on the carrying trolley 17 or the loading flat plate. Accordingly, in practical use, the container 1 is provided with a loading and unloading slot corresponding to the loading and unloading of the container, and the first lifting rod 2 in the preferred embodiment can be matched with the loading and unloading slot of the container 1 through horizontal movement by the end part thereof, so as to lift the container 1.

Further, in order to achieve stability of pre-storage, loading and unloading of the container 1, a plurality of lifting mechanisms, for example four as shown in fig. 4, are provided corresponding to the lifting of the same container 1. Meanwhile, the lifting mechanism on the right side of the loading and unloading line 8 is as shown in fig. 1 and 2, that is, the lifting mechanism includes a second pit 10 correspondingly formed, and a second hydraulic pump 9, a second lifting cylinder 11, a second lifting rod 12, a second traversing cylinder 13 and a second lifting rod 14 correspondingly disposed in the second pit 10, and the lifting mechanisms on both sides of the loading and unloading line 8 are symmetrically disposed in a cross-sectional view. Furthermore, the number of the lifting mechanisms arranged on the two sides of the loading and unloading line 8 corresponding to the loading and unloading of the same container 1 is at least two, namely after the train 15 is stopped, the number of the lifting mechanisms corresponding to the same loading flat plate is at least 4, and the lifting mechanisms correspond to the four corners of the container 1 respectively.

Further, each lifting mechanism in the synchronous loading and unloading unit is electrically connected with the control cable in a serial connection mode, so that the first lifting rod 4 and the first lifting rod 2 in each lifting mechanism can move synchronously, and each first lifting rod 2 can be matched with or separated from the loading and unloading groove of the container 1 at the same time. Meanwhile, the synchronous loading and unloading units along the loading and unloading line 8 are all electrically communicated through a synchronous joint control cable 16, and the synchronous loading and unloading units are preferably connected into the synchronous joint control cable 16 in parallel, so that the synchronous movement of the synchronous loading and unloading units can be controlled, and the independent control of the synchronous loading and unloading units can be realized. Normally, the synchronous loading and unloading units operate synchronously to realize synchronous loading and unloading of a plurality of containers 1 on the train 15.

The working process of the fixed lifting type container arraying synchronous loading and unloading system obtained through the arrangement preferably comprises a container loading process and a container unloading process.

When the containers 1 stacked in the warehouse need to be loaded in a batch manner to the train 15, i.e., a container loading process, the control process preferably includes:

(1) before a train 15 enters a station and stops, the carrying trolley 17 is controlled to run on the carrying track, containers 1 in a warehouse are sequentially carried to corresponding positions on a loading and unloading line 8, and then synchronous loading and unloading units at the positions are controlled to work, and by means of lifting motion of the lifting rods and horizontal movement of the lifting rods, the lifting rods in the synchronous loading and unloading units are matched with loading and unloading grooves in the containers at the same time, and then the lifting rods are controlled to synchronously rise for a certain height, so that the containers 1 on the carrying trolley 17 are lifted to a preset height.

The above processes are carried out in sequence, so that the containers 1 to be loaded can be prestored above the loading and unloading line 8 in sequence. It is clear that the loading of the containers 1 in the warehouse on the carrying carriages 17 can be carried out with existing handling equipment and that the carrying carriages 17 that can run on the carrying track are one or more.

(2) Pre-storing containers 1 to be loaded in the synchronous loading and unloading units respectively, controlling a train 15 to enter the station, and accurately stopping the train 15 at a preset position of a loading and unloading line 8 to realize the alignment of each loading flat plate and the corresponding synchronous loading and unloading unit;

When the containers 1 on the train 15 need to be unloaded in batches to the warehouse, i.e. the container unloading process, the control process preferably includes:

(1) controlling the train 15 to accurately stop at a preset position of the loading and unloading line 8 to realize the alignment of each loading flat plate and the corresponding synchronous loading and unloading unit, namely realizing the alignment of each container 1 on the train and the corresponding synchronous loading and unloading unit;

(2) the synchronous loading and unloading units at each position are controlled to work simultaneously through the synchronous joint control cable 16, and by utilizing the lifting motion of the lifting rods in each synchronous loading and unloading unit and the horizontal movement of the lifting rods, each lifting rod in each synchronous loading and unloading unit is matched with the loading and unloading groove on the container at the same time, so that each lifting rod is controlled to synchronously ascend to a certain height, each container 1 on the train 15 is lifted to a preset height at the same time, the simultaneous unloading of all the containers 1 is completed, and the pre-storage of all the containers 1 on the synchronous loading and unloading unit is realized.

(3) The train 15 is controlled to leave the station without stopping for an excessively long time. After the train 15 drives away from the loading and unloading line 8, the carrying trolley 17 is controlled to run on the carrying track until the carrying trolley 17 runs to a corresponding position on the loading and unloading line 8 and is locked, each lifting rod in the synchronous loading and unloading unit at the position is controlled to descend for a certain height, each lifting rod is controlled to move away from the container, the synchronous loading and unloading unit is enabled to be matched with the container, the carrying trolley 17 is further controlled to run, and the container is carried to a warehouse to be stored. The storage of the containers pre-stored on each synchronous loading and unloading unit can be completed by sequentially carrying out the processes.

Of course, the carrying trolley 17 can carry a single carrying trolley for multiple times, and a plurality of carrying trolleys 17 can also carry simultaneously, which can be specifically preferred according to actual needs. Meanwhile, in order to realize the rapid positioning of the carrying trolley 17 and the synchronous loading and unloading unit, a positioning component, such as a laser positioning component, an electronic tag code scanning identification component and the like, can be arranged between the carrying trolley 17 and the synchronous loading and unloading unit, so that the carrying trolley 17 can conveniently and rapidly move to the corresponding position on the loading and unloading line 8 and is aligned with the synchronous loading and unloading unit.
