[0003] With the expansion of the market promotion and engineering implementation of transfer devices, air rail collection and distribution systems have been developed for loading and transferring bulk materials such as coal and other ores. However, due to the characteristics of bulk materials, the existing air rail collection and distribution systems have low transfer efficiency, which restricts the development of air rail collection and distribution systems (hereinafter referred to as transfer devices). Summary of the Invention

[0004] This application aims to solve, at least to some extent, the technical problem of low transshipment efficiency in air rail collection and distribution systems for bulk materials. To this end, this application provides a transshipment device for cargo loading.

[0008] A limiting component, two of which are spaced apart along the first direction on the top surface of the base, are used to fix the cargo loading box;

[0009] When the base is in the first position, one of the limiting components is located below the discharge port of the feeding device; when the base is in the second position, the other limiting component is located below the discharge port of the feeding device.

[0010] In some embodiments, the changing device further includes a track arranged along a first direction, and a walking mechanism is provided at the bottom end of the base, the walking mechanism being slidably engaged with the track.

[0011] In some embodiments, the track includes two parallel running rails, each with a limit plug at both ends.

[0012] In some embodiments, the base is operable to rise and fall; when the base is in the first position or the second position, the base rises to a second target height; when the base moves between the first position and the second position, the base falls to a first target height.

[0013] In some embodiments, the base includes a support platform, a plurality of telescopic support legs disposed at the bottom end of the support platform, and a drive member, wherein the bottom end of the telescopic support legs slides in engagement with the track, and the drive member drives the base to reciprocate along the track.

[0014] In some embodiments, the telescopic support leg includes a first support base, a second support base, and a telescopic mechanism disposed between the first support base and the second support base. The top end of the first support base is connected to the bottom surface of the support platform, and the bottom end of the second support base slides with the track.

[0015] In some embodiments, the telescopic mechanism includes telescopic outriggers and at least one hydraulic mechanism, the top end of the telescopic rod of the hydraulic mechanism being connected to the first support base.

[0016] In some embodiments, there are two hydraulic mechanisms, with the telescopic outrigger positioned between the two hydraulic mechanisms.

[0017] In some embodiments, a connecting longitudinal beam is provided between the second support seats of two adjacent telescopic support legs.

[0018] In some embodiments, the limiting component is characterized in that it includes at least one pair of limiting blocks, the two limiting blocks being disposed opposite to each other along a first direction.

[0019] In some embodiments, the top of each limiting block of the same pair of limiting structures is provided with an inclined surface, and the two inclined surfaces are arranged opposite to each other.

[0020] A cargo loading and transshipment system, comprising:

[0021] Two feeding devices are arranged side by side along the first direction;

[0022] A transfer device is provided between the two unloading devices;

[0023] A cargo loading container is used to hold the cargo in the unloading device;

[0024] The cargo loading and transshipment device.

[0025] A cargo loading method, applied to a cargo loading transshipment system, includes a moving operation and a transshipment operation, wherein...

[0026] The transshipment operation includes: loading goods into the empty container when there is an empty container at the discharge port and the base is at the second target height, while simultaneously setting an empty container onto another limiting component;

[0027] The mobile operation includes:

On the one hand, it can ensure that the container set in the limiting component can be accurately located below the discharge port. On the other hand, the limiting component can also prevent the container from relative displacement with the base or even detaching from the base during the base movement.

[0038] The base of the changing device in the changing system is driven by two limiting components to move alternately to below the discharge port. When the base moves, it is at the first target height. When one limiting component is below the discharge port, the base can rise to the second target height. The first target height is lower than the second target height. The first and second target heights can be customized according to the height of the discharge port to avoid the container set on the base from colliding with the discharge port during the base movement. The base can also rise to the second target height to avoid the splashing of bulk materials and reduce the potential energy of the bulk materials when they fall, thus reducing dust.

[0039] Alternating placement of empty containers on two limit components reduces the time spent loading, transshipping, and transferring bulk materials, thereby improving the efficiency of bulk material loading and transportation. Attached Figure Description

[0049] This application is described below with reference to the accompanying drawings and specific embodiments:

[0050] Example 1

[0051] like Figure 1 and Figure 2 As shown, this embodiment provides a cargo loading and unloading device, located below the unloading device 400. The top of the unloading device 400 is equipped with a hopper or a belt conveyor system for transporting bulk materials, and the bottom of the unloading device 400 is equipped with a discharge port 410. (Refer to...) Figure 1 The loading and unloading device includes a base 100 and a limiting component. The base 100 is operable to reciprocate along a first direction to switch between a first position and a second position. Two limiting components are spaced apart on the top surface of the base 100 along the first direction to fix the cargo loading container. The two limiting components are a first limiting component 210 and a second limiting component 220. Both limiting components are used to place the container 500 and limit the container 500. On the one hand, it can ensure that the container 500 placed in the limiting component can be accurately located below the discharge port 410. On the other hand, the limiting component can also prevent the container 500 from relative displacement with the base 100 or even detaching from the base 100 during the movement of the base 100.

[0052] During movement, the base 100 can stop at a first position and a second position. When the base 100 is in the first position, one of the limiting components is located below the discharge port; when the base 100 is in the second position, the other limiting component is located below the discharge port. That is, the movement of the base 100 will cause the two limiting components to move alternately to below the discharge port 410. Then the container 500 placed on the limiting components can also alternately be located below the discharge port or away from the discharge port.

[0053] Understandably, the first limiting component 210 and the second limiting component 220 on the top surface of the base 100 can both be used to place the container 500. Therefore, it is understandable that empty containers 500 can be alternately placed on the first limiting component 210 and the second limiting component 220 to shorten the time interval between loading materials into different containers 500. That is, after the empty container 500 on the first limiting component 210 is filled, the base 100 is driven so that the empty container 500 on the second limiting component 220 is located at the discharge port 410 for loading materials. At this time, the first limiting component 210... The container 500 loaded with materials is located far from the discharge port 410 and can be transported away by the transfer device. At the same time, the transfer device can also place an empty container 500 back on the first limiting component 210. After the container 500 on the second limiting component 220 is full, the empty container 500 on the first limiting component 210 can be moved to the discharge port 410. While one container 500 is being transferred, another container 500 is being loaded with materials, which reduces the time spent loading, transshipping and transferring bulk materials and improves the loading and transportation efficiency of bulk materials.

[0054] In some embodiments, the changing device further includes a track arranged along a first direction, and a traveling mechanism is provided at the bottom end of the base 100. The traveling mechanism slides with the track, limiting the direction of movement of the base 100 and improving the accuracy of the base 100's movement. Further, referring to... Figure 1 The track includes two parallel travel rails 300 to further restrict the movement path of the base 100. Of course, in order to prevent the base 100 from sliding off the track due to inertia, limit plugs (not shown in the drawings) are provided at both ends of the travel rails 300 to limit the range of movement of the base 100.

[0055] In some embodiments, the base 100 is operable to be raised and lowered; when the base 100 is in a first position or a second position, the base 100 can rise to a second target height so that the container 500 can receive materials; before the base 100 needs to move in a first direction, the base 100 is lowered to the first target height; when the base 100 moves between the first position and the second position, the base 100 lowers to the first target height, which is lower than the second target height, and the first target height and the second target height can be customized according to the height of the discharge port 410 to avoid the container 500 set on the base 100 from colliding with the discharge port 410 during the movement of the base 100, and the base 100 can rise to the second target height to avoid the splashing of bulk materials, while reducing the potential energy of the bulk materials when falling and reducing dust.

[0056] In some embodiments, the base 100 includes a support platform 110, a plurality of telescopic support legs 120 disposed at the bottom end of the support platform 110, and a driving member. The driving member drives the base 100 to reciprocate along the track. The driving member may include a motor and a drive wheel, which cooperates with the track. The base 100 may have only one driving member, or each telescopic support leg 120 may have a driving member at its bottom end. Of course, the driving member may also include a braking structure to help the base 100 brake quickly. The top surface of the support platform 110 is the top surface of the base 100, and the telescopic support legs 120 are used to drive the support platform 110 to rise and fall to change the height of the base 100.

[0057] Reference Figure 1 and Figure 2 The telescopic support leg 120 includes a first support base 121, a second support base 122, and a telescopic mechanism disposed between the first support base 121 and the second support base 122. The top end of the first support base 121 is connected to the bottom surface of the support platform 110, and the bottom end of the second support base 122 is disposed on the ground. The telescopic mechanism includes at least one hydraulic mechanism 123. The top end of the telescopic rod of the hydraulic mechanism 123 is connected to the first support base 121. The extension and retraction of the telescopic rod of the hydraulic mechanism 123 drives the lifting and lowering of the support platform 110, and the container 500 disposed on the top of the support platform 110 also lifts and lowers accordingly. Of course, the telescopic mechanism may also be a pneumatic mechanism or other devices that can achieve stable lifting and lowering of the support platform 110.

[0058] In some embodiments, the telescopic mechanism includes two hydraulic mechanisms 123 and a telescopic outrigger 124. The telescopic outrigger 124 is disposed between the two hydraulic mechanisms 123. The telescopic outrigger 124 can only extend and retract in the vertical direction. It is understood that by setting the telescopic outrigger 124, the direction of extension and retraction of the hydraulic mechanisms 123 is restricted, thereby improving the stability of the telescopic mechanism and reducing the occurrence of accidents.

[0059] Furthermore, the telescopic outrigger 124 includes a guide cylinder and a guide rod slidably disposed within the guide cylinder. The guide cylinder is connected to the second support base 122, and the guide rod is connected to the first support base 121. The axis of the guide cylinder and the axis of the guide rod are both vertical. Of course, the maximum length of the guide rod disposed within the guide cylinder is greater than the stroke of the hydraulic mechanism 123.

[0060] Reference Figure 1In some embodiments, the base 100 is provided with six telescopic support legs 120. These six telescopic support legs 120 are divided into two groups, each group comprising three telescopic support legs 120. The three telescopic support legs 120 are equally spaced along a first direction, and the two groups of telescopic support legs 120 are arranged opposite each other to improve the stability of the base 100 and provide stable support for containers 500 at different positions. To further improve the stability of the entire transshipment device, a connecting longitudinal beam 127 is provided between the second support seats 122 of adjacent telescopic support legs 120 in the same group. The connecting longitudinal beam 127 improves the strength of the base 100, extends its service life, and enables the transshipment device to maintain good transshipment efficiency for a long time.

[0061] The limiting component includes at least one pair of limiting blocks 230, which are arranged opposite each other along a first direction. The distance between the two limiting blocks 230 is the width of the container 500, and the length direction of the limiting blocks 230 is perpendicular to the first direction. This allows the container 500 to be lifted and moved out by the transfer device along the length direction of the limiting blocks 230. Considering that the dimensions of some containers 500 may change slightly during transportation, the distance between the two limiting blocks 230 of the limiting component is slightly larger than the width of the corresponding container 500, so that the container 500 can be smoothly placed between the two limiting blocks 230. Furthermore, the top of each limiting block 230 in the same pair of limiting structures is provided with a ramp 231, which is arranged opposite each other to guide the container 500. This allows the container 500 to be placed on the first platform without precise alignment, further improving the transshipment efficiency.

[0062] In some embodiments, a feeding device 400 and two transfer devices may be provided. The two transfer devices are respectively arranged in parallel on both sides of the feeding device 400. The track of the transfer device at the feeding device 400 is perpendicular to the first direction, so as to alternately feed empty containers 500 onto the first limiting component 210 and the second limiting component 220.

[0063] In some embodiments, two feeding devices 400 and a transfer device are provided. The two feeding devices 400 are arranged side by side along a first direction. The track of the transfer device is arranged between the two feeding devices 400 and is arranged below the two feeding devices 400. The two feeding devices 400 are a first feeding device 420 and a second feeding device 430. The first feeding device 420 corresponds to the first limiting component 210 and is located on one side of the transfer device. The second feeding device 430 corresponds to the second limiting component 220 and is located on the other side of the transfer device. The base 100 drives the first limiting component 210 and the second limiting component 220 to move alternately to the discharge port 410 that is on the same side and adjacent to the limiting component.

[0064] Example 2

[0065] Based on the same inventive concept, and referring to Figure 3 This embodiment also provides a cargo loading and transshipment system, including two unloading devices 400, a transfer device, a cargo loading box, and the aforementioned transshipment device, wherein the two unloading devices 400 are arranged side by side along the first direction; the transfer device is located between the two unloading devices 400; the cargo loading box is used to hold the cargo in the unloading devices 400, and the cargo loading box can be selected as a container 500.

[0066] Example 3

[0067] Based on the same inventive concept, this application also provides a cargo loading method, applied to the above-mentioned cargo loading transshipment system, including moving operations and transshipment operations.

[0068] The transshipment operation includes: loading goods into the empty container 500 when an empty container 500 is set at the discharge port 410 and the base 100 is at the second target height, while simultaneously setting an empty container 500 onto another limiting component.

[0069] The moving operation includes: lowering the base 100 to a first target height, moving the base 100 so that the empty container 500 is below the discharge port 410; and raising the base 100 to a second target height.

[0070] Repeated movement and transshipment operations can continuously and efficiently complete the transshipment and transfer of bulk materials.

[0071] Example 4,

[0072] Reference Figure 3 Applying the above-described transshipment method to the transshipment system in Example 2, i.e., the cargo loading transshipment system includes two unloading devices 400 and one transfer device. The two unloading devices 400 are the first unloading device 420 and the second unloading device 430, respectively. The specific transportation process is as follows:

[0073] Step 100: Position the base 100 at the second target height. At this time, the second limiting component 220 is located below the discharge port 410 of the second feeding device 430. Use the transfer device to place an empty container 500 on the first limiting component 210.

[0074] Step 110: Lower the base 100 to the first target height and move the empty container 500 on the first limiting component 210 to below the discharge port 410 of the first unloading device 420.

[0075] Step 120: Raise the base 100 to the second target height, and the first unloading device 420 begins to load goods into the empty container 500. At the same time, the transfer device places another empty container 500 onto the second limiting component 220.

[0076] Step 130: After the empty container 500 on the first limiting component 210 is loaded with goods, close the discharge port 410 of the first unloading device 420 and lower the base 100 to the first target height.

[0077] Step 140: Move the base 100 toward the second feeding device 430 so that the empty container 500 on the second limiting component 220 is below the discharge port 410 of the second feeding device 430.

[0078] Step 150: Raise the base 100 to the second target height, and the second unloading device 430 begins to load goods into the empty container 500. At the same time, the empty container 500 loaded with goods on the first limiting component 210 is transported away by the transfer device, and another empty container 500 is placed on the first limiting component 210.

[0079] By repeating steps 110-150, empty containers 500 can be alternately placed on the first limiting component 210 and the second limiting component 220. The time interval between loading materials into different containers 500 is short. While one container 500 is being transferred, another container 500 is being loaded with materials, which reduces the time spent loading, transshipping and transferring bulk materials, and improves the loading and transportation efficiency of bulk materials.

[0080] Example 5

[0081] Based on the same inventive concept, and referring to Figure 4 This embodiment also provides another cargo loading and transshipment system, wherein the cargo loading and transshipment device includes two transfer devices and a unloading device 400. The two transfer devices are a first transfer device 610 and a second transfer device 620. The first transfer device 610 and the first limiting component 210 are located on the same side of the unloading device 400, and the second transfer device 620 and the second limiting component 220 are located on the same side of the unloading device 400.

[0082] Reference Figure 4 If the transshipment method in Example 3 is applied to the transshipment system in Example 5, then the specific transportation process is as follows:

[0083] Step 200: Position the base 100 at the second target height. At this time, the second limiting component 220 is located below the discharge port 410 of the unloading device 400. Place an empty container 500 on the first limiting component 210 through the first transfer device 610.

[0084] Step 210: Lower the base 100 to the first target height, and move the empty container 500 on the first limiting component 210 to below the discharge port 410 of the unloading device 400. At this time, the second limiting component 220 is located below the second transfer device 620.

[0085] Step 220: Raise the base 100 to the second target height, and the unloading device 400 begins to load goods into the empty container 500. At the same time, the second transfer device 620 places another empty container 500 onto the second limit component 220.

[0086] Step 230: After the empty container 500 on the first limiting component 210 is loaded with goods, close the discharge port 410 of the unloading device 400 and lower the base 100 to the first target height.

[0087] Step 240: Move the base 100 below the first transfer device 610 so that the empty container 500 on the second limiting component 220 is below the discharge port 410 of the unloading mechanism.

[0088] Step 250: Raise the base 100 to the second target height, and the unloading device 400 begins to load goods into the empty container 500. At the same time, the empty container 500 loaded with goods on the first limiting component 210 is transported away by the first transfer device 610, and another empty container 500 is placed on the first limiting component 210.
