[0025] Example 1:

[0026] This embodiment is a fast quantitative loading system for air rail freight containers, such as Figure 1 、 2 This embodiment comprises: a steel structure frame 3, the bottom of which passes through an empty rail 1 and its empty rail freight car 2. The steel structure frame is mounted, from top to bottom, with a belt conveyor head 4, at least two buffer bins 5 with discharge ports, and at least two sets of parallel weighing bins 6. Below each set of weighing bins are respectively provided a mobile buffer bucket 7 capable of alternately loading vehicles. Below each mobile buffer bucket is provided a telescopic loading chute 8 capable of moving with the mobile buffer bucket.

[0027] The sky rail is a transport facility that does not contact the ground, and the goods are hung below the sky rail. The sky rail described in this embodiment is a hanging container 9, which allows the container to be transported along the sky rail. Figure 1 Enter the loading station one by one in the direction of arrow B (due to the limitation of drawing, Figure 1 (Only one set of two containers is shown in the figure) is loaded with coal. Since aerial rail freight cars move at a high speed, while freight cars at conventional automated bulk material loading stations move at a lower speed, this embodiment primarily addresses the problem of increasing loading speed.

[0028] In order to solve the problem of the high speed of the empty rail freight car during the loading process, this embodiment is equipped with multiple weighing bins, which alternately batch and weigh materials to speed up the quantitative weighing speed. At the same time, a movable buffer bucket is provided. During the process of unloading into the container, it moves forward with the empty rail freight car to buy time for filling the container.

[0029] In this embodiment, the containers entering the loading station one by one can be divided into several groups, and a group of containers can be two or four. Figure 1The two sets of containers are shown in FIG. 1, which are 1# container and 1# container. The multiple sets of weighing bins are alternately filled and weighed, and are alternately unloaded to a few sets of containers. For example, a set of two containers is arranged opposite to four weighing bins, the first two weighing bins are filled with the first container in the set of containers, and the last two weighing bins are filled with the second container. In this way, the round trip can keep up with the fast moving pace of the overhead trolley.

[0030] To solve the problem of fast movement of the overhead trolley, the movable buffer hopper moves with the container during unloading, which is equivalent to slowing down the movement of the overhead trolley. The movable buffer hopper can have multiple movement schemes, for example, a trolley is arranged to carry a buffer hopper and move with the container. The movement speed of the movable buffer hopper should be lower than that of the overhead trolley, and the movable buffer hopper receives the unloading of different quantitative bins during movement to achieve the alternate unloading of different weighing bins.

[0031] The buffer bin in this embodiment can have multiple discharge ports to cope with multiple weighing bins. As shown in FIG. 1, Figure 1 、 2 Four weighing bins are arranged, so four discharge ports are arranged in the buffer bin, and each discharge port is provided with a batching gate.

[0032] The steel structure frame and the buffer bin described in this embodiment can be conventional, or multiple buffer bins can be arranged according to the needs to cooperate with multiple weighing bins, and multiple belt conveyors can be arranged to solve the problem of fast material conveying.

[0033] Embodiment two:

[0034] This embodiment is an improvement of the above-mentioned embodiment, which is a refinement of the movable buffer hopper of the above-mentioned embodiment. The movable buffer hopper described in this embodiment comprises a conical hopper body 701, two pairs of rollers 702 are installed on both sides of the conical hopper body, the rollers are supported by a track 703 consistent with the direction of the overhead trolley, and can move forward and backward along the track (in the direction of arrow C in FIG. 1). Figure 1 The track is supported by a track bracket 704, and the track bracket is fixedly connected with the steel structure frame.

[0035] The trolley type movement adopted in this embodiment is a very short track, and the trolley carries the hopper and moves the hopper forward and backward. The track is installed on the bracket, and the bracket is fixed on the steel structure frame.

[0036] Embodiment three:

[0037] This embodiment is an improvement of the above-mentioned embodiment, which is a refinement of the buffer bin of the above-mentioned embodiment. The buffer bin described in this embodiment is two buffer bins arranged on the same plane, each buffer bin is provided with two discharge ports, and each discharge port is provided with a respective batching gate.

[0038] The buffer bin described in the embodiment is two buffer bins arranged on the same plane. The lower half of the buffer bin is arranged as two square cones. Each square cone is equipped with a batching gate. The four batching gates are arranged on the same plane and are respectively arranged at the bottom of the four square cones and correspond to the four weighing bins below.

[0039] Embodiment four:

[0040] The embodiment is an improvement of the above-mentioned embodiment and is a refinement of the above-mentioned embodiment about the weighing bin. The weighing bin described in the embodiment is two groups, each group has two, a total of four weighing bins, and each weighing bin is respectively provided with a respective unloading gate.

[0041] The weighing bins are arranged on the same plane and their positions correspond to the batching gates of the buffer bin and the buffer bin one by one.

[0042] Embodiment five:

[0043] The embodiment is a loading method of a rapid quantitative loading system using the above-mentioned empty rail freight container.

[0044] Each two adjacent empty rail freight cars are coded as a group. Each cycle is a group of two empty rail freight cars and the containers carried by them are loaded. Each group of containers is numbered, the former is 1# container and the latter is 2# container.

[0045] Two movable buffer hoppers and telescopic loading chutes are respectively numbered as: 1# buffer hopper and 1# telescopic loading chute on the right side, 2# buffer hopper and 2# telescopic loading chute on the left side. The position of the buffer hopper when the container enters the loading position is in front of the loading position, and the position of the buffer hopper when the container leaves the loading position is behind the loading position. The loading position refers to the empty rail section that an empty rail freight car passes through for loading and unloading operation.

[0046] The weighing bins are respectively numbered according to the direction of the empty rail freight car entering as: 1 group of weighing bins on the right and 2 groups of weighing bins on the left. The front of 1 group of weighing bins is 1-1# weighing bin and the rear is 1-2# weighing bin. The front of 2 group of weighing bins is 2-1# weighing bin and the rear is 2-2# weighing bin, as shown in Figure 3 The arrow B indicates the direction of the empty rail freight car entering.

[0047] The unloading gates of the buffer bin are respectively numbered according to the direction of the empty rail freight car entering as: 1 group of gates on the right and 2 groups of gates on the left. The front of 1 group of gates is 1-1# gate and the rear is 1-2# gate. The front of 2 group of gates is 2-1# gate and the rear is 2-2# gate. Since the unloading gates of the buffer bin correspond to the weighing bins one by one, the gate numbers can refer to the positions of the weighing bins in Figure 3 .

[0048] The steps of the method are as follows, and the flow is as shown inFigure 4 as shown:

[0049] Step 1, batching: Before and during the process of entering the loading position, the batching gate of the buffer bin is opened in sequence to batch the four weighing bins, the sequence is: 1-1# weighing bin, 1-2# weighing bin, 2-1# weighing bin, 2-2# weighing bin;

[0050] The above batching process refers to the process of batching in a certain stage of the container loading process. Because in the continuous loading process of multiple containers, the containers enter the loading position one after another for continuous loading, the emptying sequence of the weighing bin is 1-1# weighing bin, 1-2# weighing bin, 2-1# weighing bin, 2-2# weighing bin, therefore, the emptying weighing bin can only be batched in this order, but when the loading process is at the beginning, all the weighing bins are empty, at this time the four gates of the buffer bin can be opened at the same time to batch the four weighing bins at the same time to improve the batching efficiency, or first load two, then load two, etc. Various sequences only need to adjust the control software to meet the various needs of the site.

[0051] Step 2, 1# container front half loading: 1-1# weighing bin is first batched and weighed, at this time 1# buffer hopper is located in front of the loading position, and then 1# container front half enters the front of the loading position; 1-1# weighing bin opens the discharge gate, 1-1# weighing bin through 1# buffer hopper and 1# telescopic loading chute to 1# container front half, at the same time 1# buffer hopper and 1# telescopic loading chute start to move to the rear of the loading position, when 1# buffer hopper and 1# telescopic loading chute reach the middle of 1# container, 1# container front half is filled with material;

[0052] When the 1-1# weighing bin discharge gate is opened, 1# buffer hopper and 1# telescopic loading chute also start to move to the rear of the loading position, at this time the empty rail freight car is also advancing, the moving speed of 1# buffer hopper and 1# telescopic loading chute is lower than that of the empty rail freight car, which is equivalent to reducing the movement speed of the empty rail freight car, thereby gaining time for unloading. If there is no movement of the buffer hopper and the telescopic loading chute, the empty rail freight car will quickly pass through the discharge port of the buffer bin, and the unloading flow speed of the material cannot keep up with the movement speed of the empty rail freight car, so that the material cannot fill the container. Therefore, the movement of the buffer hopper and the telescopic loading chute during unloading is very necessary, thereby solving the problem of too fast movement of the empty rail freight car.

[0053] Step 3, 1# container rear half loading: 1-2# weighing bin is dosed and weighed; when 1# buffer hopper and 1# telescopic container loading chute reach the middle of 1# container, 1-1# weighing bin is emptied, the discharge gate of 1-1# weighing bin is closed, and the discharge gate of 1-2# weighing bin is opened, 1-2# weighing bin is unloaded through 1# buffer hopper and 1# telescopic container loading chute to the rear half of 1# container; when the rear half of 1# container reaches the rear of loading position, 1# buffer hopper and 1# telescopic container loading chute also reach the rear of loading position, at this time, 1-2# weighing bin is emptied, the rear half of 1# container is fully loaded, the discharge gate of 1-2# weighing bin is closed, 1# container is fully loaded and leaves the loading position, and then 1# buffer hopper and 1# telescopic container loading chute return to the front of loading position;

[0054] In actual loading process, the discharge gate of 1-2# weighing bin should be opened before 1# buffer hopper and 1# telescopic container loading chute reach the middle of 1# container, that is, the opening time of discharge gate of 1-1# weighing bin and the opening time of discharge gate of 1-2# weighing bin overlap, so that the loading is more uniform, and the accumulation of bulk material in the middle of container is avoided.

[0055] After one container is fully loaded, the buffer hopper and telescopic container loading chute have reached the rear of loading position, and cannot continue to move with the empty rail freight car, and there is no need to move forward, so it needs to be reset to return to the front of loading position and wait for the arrival of the next empty rail freight car. However, resetting takes time, and at this time the next empty rail freight car has reached the front of loading position and will soon enter the loading position. If there is only one set of movable buffer hopper, it is impossible to cope with the continuous entry of the fast-moving empty rail freight car into the loading position, so two sets of movable buffer hoppers are needed to work alternately to achieve the purpose of coping with the fast-moving empty rail freight car.

[0056] Step 4, 2# container front half loading: 2-1# weighing bin is dosed and weighed; at this time, 2# buffer hopper is located at the front of loading position, and then the front half of 2# container enters the front of loading position; the discharge gate of 2-1# weighing bin is opened, and 2-1# weighing bin is unloaded through 2# buffer hopper and 2# telescopic container loading chute to the front half of 2# container, and at the same time, 2# buffer hopper and 2# telescopic container loading chute start to move to the rear of loading position, and when 2# buffer hopper and 2# telescopic container loading chute reach the middle of 2# container, the front half of 2# container is fully loaded with material;

[0057] The unloading of 2# container is actually a repetition of the unloading of 1# container, but 2# buffer hopper and 2# telescopic container loading chute are used to gain time for unloading the continuously running empty rail freight car.

[0058] Step 5, 2# container rear half loading: 2-2# weighing bin is dosed and weighed; when 2# buffer hopper and 2# telescopic container loading chute reach the middle of 2# container, 2-1# weighing bin is emptied, the discharge gate of 2-1# weighing bin is closed, and the discharge gate of 2-2# weighing bin is opened, 2-2# weighing bin is unloaded through 2# buffer hopper and 2# telescopic container loading chute to the rear half of 2# container; when the rear half of 2# container reaches the rear of the loading position, 2# buffer hopper and 2# telescopic container loading chute also reach the rear of the loading position, at this time, 2-2# weighing bin is emptied, the rear half of 2# container is fully loaded, the discharge gate of 2-2# weighing bin is closed, 2# container is fully loaded and leaves the loading position, and then 2# buffer hopper and 2# telescopic container loading chute return to the front of the loading position; then return to step 1 to load the next group of containers.

[0059] Application example:

[0060] The empty rail container coal rapid quantitative loading capacity:

[0061] 1) Double car marshalling into position (for example: 1# and 2# containers are a group, 3# and 4# containers are a group, and so on) loading interval time is 48s;

[0062] 2) 75 pairs of containers are loaded per hour, and a single container load is 32 tons, so the total amount of empty rail loading per hour is about 75x64=4800 t / h;

[0063] According to the daily running time: 21h;

[0064] Annual transportation time: 270 days;

[0065] Annual transport volume can reach: 4800x21x270=2721.6 million tons.

[0066] Loading process:

[0067] 1) Feeding: after the system starts the loading instruction, the feeding belt conveyor feeds into the loading station buffer bin, and a high-low level radar is arranged in the buffer bin to real-time feedback the material level in the bin;

[0068] 2) Buffering and weighing: when the buffer bin level reaches the dosing bin level, the weighing bin starts the weighing instruction, real-time weighing, and the total capacity of the four weighing hoppers is 20 tons, and the weighing time is about 5s.

[0069] 3) Positioning and loading: after the double car marshalling reaches the designated loading position, the system real-time starts the unloading and loading instruction, the weighing bin unloads to the material distribution device, the mobile loading material distribution device performs the loading action, and the working head stretches into the loading range of the container to unload, and at the same time, the horizontal movement of the loading device synchronously completes the horizontal movement of the material on the flat car

[0070] The moving speed range of the mobile loading and distributing device is 1.0-1.5 km / h (about 0.3-0.4 m / s), the moving horizontal distance is about 3 m, and the whole loading and distributing moving time is about 10 s.

[0071] After the loading operation is completed for about 10 s, the mobile loading and distributing device retreats to the avoiding space and waits for the next pair of vehicles to be positioned.

[0072] 4) The next weighing is completed during the waiting process, and the vehicles are unloaded and loaded after being positioned, and the cycle is repeated.

[0073] The loading station is composed of:

[0078] The structure periphery is usually surrounded by flame-retardant cold- resistant sandwich color steel plate, or other surrounding ways and materials recognized by the customer can also be used. The structure inside is provided with perfect stairs, fences and pedestrian maintenance channels.

[0079] 3) Two buffer bins:

[0080] The buffer bin capacity is not less than 300 tons, and can be increased according to the length of the feeding belt to meet the buffering demand of coal.

[0081] The bin body usually adopts square taper structure, and round structure can be used when the coal quality and moisture are large and the fluidity is poor. Wear-resistant lining plate is laid in the bin to improve the service life of the bin body, and the lining plate can be selected from 16Mn, NM400, stainless steel and other materials.

[0082] 4) Four weighing bins:

[0083] Each weighing bin is composed of two 20-ton hoppers, and six or eight weighing sensors are used in each weighing bin to improve the weighing accuracy.

[0084] Each 32-ton container is weighed by two weighing bins during loading, each weighing bin weighs 16 tons, and the two hoppers of the weighing bin alternately weigh the operation. The specific operation is matched with the mobile loading and distributing device.

[0085] The bin body usually adopts square cone structure, and round structure can be adopted when the coal quality and moisture are large and the fluidity is poor. Wear-resistant lining plate is laid in the bin to improve the service life of the bin body, and the lining plate can be selected from 16Mn, NM400, stainless steel and other materials.

[0086] 5) Hydraulic gate:

The gate plate is supported by heavy load roller bearings, and the upper surface is paved with a wear-resistant layer.

[0088] 6) Mobile buffer hopper and telescopic loading chute:

[0089] A mobile buffer hopper is arranged under the weighing bin, which comprises a buffer hopper, a gate, a mobile telescopic loading chute, a moving device, a rail and a frame.

[0090] According to the actual gap between the container and the empty rail frame beam, the opening size of the loading chute is about 1680*760mm, the hourly throughput can reach 5700 tons, the 16-ton unloading time is about 10s, and the requirement of rapid loading and material distribution can be met.

[0091] Finally, it should be pointed out that the above is only used to illustrate the technical solutions of the present application and is not limited. Although the present application has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that the technical solutions of the present application (such as the form of the loading station, the form of the empty rail, the sequence of the steps, etc.) can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.

The weighing bins are numbered according to the direction of entry of the aerial rail freight car: the right is the weighing bin of group 1, and the left is the weighing bin of group 2; the weighing bin in front of group 1 is the weighing bin 1-1#, and the weighing bin behind it is the weighing bin 1-2#; the weighing bin in front of group 2 is the weighing bin 2-1#, and the weighing bin behind it is the weighing bin 2-2#; The unloading gates of the buffer bin are numbered according to the direction of entry of the aerial rail freight car: the right is gate group 1, the left is gate group 2; the front of gate group 1 is gate 1-1#, and the back is gate 1-2#; the front of gate group 2 is gate 2-1#, and the back is gate 2-2#; The steps of the method are as follows: Step 1, batching: Before and during a group of containers enter the loading bay, the buffer bin opens the batching gates in sequence to batch the four weighing bins, in the following order: 1-1# weighing bin, 1-2# weighing bin, 2-1# weighing bin, and 2-2# weighing bin; Step 2, loading the front half of container 1#: 1-1# weighing bin first batches and weighs the materials. At this time, 1# buffer hopper is located in front of the loading position, and then the front half of container 1# enters the front of the loading position; 1-1# weighing bin opens the unloading gate, and 1-1# weighing bin loads the front half of container 1# through 1# buffer hopper and 1# telescopic loading chute. At the same time, 1# buffer hopper and 1# telescopic loading chute start to move toward the rear of the loading position. When 1# buffer hopper and 1# telescopic loading chute reach the middle of container 1#, the front half of container 1# is fully loaded with materials; Step 3, loading the back half of container 1#: 1-2# weighing bins complete the batching and weighing; when 1# buffer hopper and 1# telescopic loading chute reach the middle of container 1#, 1-1# weighing bin is emptied, 1-1# weighing bin closes its discharge gate, and 1-2# weighing bin opens its discharge gate. 1-2# weighing bin unloads the back half of container 1# through 1# buffer hopper and 1# telescopic loading chute; when the back half of container 1# reaches the rear of the loading bay, 1# buffer hopper and 1# telescopic loading chute also reach the rear of the loading bay, 1-2# weighing bins are emptied, the back half of container 1# is filled, 1-2# weighing bins close their discharge gate, container 1# is loaded and leaves the loading bay, and 1# buffer hopper and 1# telescopic loading chute return to the front of the loading bay; Step 4, loading the front half of container 2#: 2-1# weighing bin completes the batching and weighing; at this point, the 2# buffer hopper is located in front of the loading bay, and then the front half of container 2# enters the front of the loading bay; the 2-1# weighing bin opens the unloading gate, and the 2-1# weighing bin loads the front half of container 2# through the 2# buffer hopper and the 2# telescopic loading chute. At the same time, the 2# buffer hopper and the 2# telescopic loading chute begin to move toward the rear of the loading bay. When the 2# buffer hopper and the 2# telescopic loading chute reach the middle of container 2#, the front half of container 2# is fully loaded with materials; Step 5, loading the back half of container 2#: 2-2# weighing bin is loaded and weighed; when 2# buffer hopper and 2# telescopic loading chute reach the middle of 2# container, 2-1# weighing bin is emptied, 2-1# weighing bin closes the unloading gate, and 2-2# weighing bin opens the unloading gate at the same time, and 2-2# weighing bin unloads the back half of 2# container through 2# buffer hopper and 2# telescopic loading chute; when the back half of 2# container reaches the rear of the loading position, 2# buffer hopper and 2# telescopic loading chute also reach the rear of the loading position, at this time 2-2# weighing bin is emptied, the back half of 2# container is filled, 2-2# weighing bin closes the unloading gate, 2# container is loaded and leaves the loading position, and 2# buffer hopper and 2# telescopic loading chute return to the front of the loading position; then return to step 1 to enter the loading of the next group of containers.
