Description

Technical Field

[0001] The present application belongs to the technical field of cargo transportation equipment, and specifically relates to a cargo transportation device. Background Art

[0002] Material warehousing is the activity of storing and preserving goods and items in warehouses. The material warehousing process includes multiple links such as receiving, shelving, and inventory management. In the existing technology, material transfer vehicles are usually used to transport materials. However, the amount of materials that can be transported by transfer vehicles at a time is small, and the transportation efficiency is low.

[0003] In order to solve this technical problem, a discharge device for cargo storage with publication number CN219155437U was proposed, which includes a storage bin and a lifting assembly. Materials are loaded through the lifting assembly, and then temporarily stored in the storage bin. After the storage bin is full of materials, the materials are transported to the warehouse in a unified manner, thereby increasing the single-time delivery volume of materials and thus improving the material transportation efficiency. However, due to the different heights of the materials, the lifting assembly needs to adjust its vertical height or deflection angle when transporting the materials, and the storage bin will also move synchronously with the movement of the lifting assembly. When there are more materials stored in the storage bin, the driving pressure of the driving components that drive the lifting assembly and the storage bin is relatively large, and is limited by the power upper limit of the driving components. Therefore, the storage bin cannot be loaded with more materials, resulting in limited improvement in the material transportation efficiency of the discharge device. Utility Model Content

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The cargo transport device of the present application includes a unloading unit and a cargo storage bin, wherein the unloading unit is used to transfer materials, carries the materials through the cargo board and dumps the materials into the transfer mechanism, and since the transfer mechanism includes a receiving state and an unloading state, when there is a lot of material in the transfer mechanism, it can switch from the receiving state to the unloading state, thereby unloading the materials in the transfer mechanism into the cargo storage bin; in this way, on the one hand, it saves the operation of dumping the materials into the cargo storage bin every time the cargo board is loaded with materials, and the materials can be dumped into the transfer mechanism for temporary storage, shortening the working stroke of the cargo board, thereby improving the unloading efficiency of the cargo transport device; on the other hand, when there is a lot of material stored in the transfer mechanism, the materials can be unloaded into the cargo storage bin by switching to the unloading state, thereby reducing the bearing pressure of the transfer mechanism, increasing the amount of materials that the cargo transport device can carry in a single unloading process, and further improving the cargo transport efficiency of the cargo transport device.

With such arrangement, when there is a lot of material in the transfer mechanism and it needs to be unloaded to the cargo holding bin, since the cargo holding bin is located below the transfer mechanism, it is only necessary to drive the movable base plate from the receiving position to the unloading position through the first drive component, and the material can fall into the cargo holding bin below under the action of its own weight.

[0043] like Figures 1 to 4 As shown, a cargo transport device includes a mounting frame 1, and a cargo storage bin 2 and a unloading unit mounted on the mounting frame 1. The unloading unit includes a cargo transport mechanism and a transfer mechanism. The cargo transport mechanism includes a cargo plate 3. The cargo plate 3 can carry materials and dump the materials into the transfer mechanism. The transfer mechanism has a receiving state for storing materials and an unloading state for delivering materials to the cargo storage bin 2. The transfer mechanism can switch between the receiving state and the unloading state.

[0044] The cargo transport device of the present application includes a unloading unit and a cargo storage bin 2, wherein the unloading unit is used to transfer materials, carries the materials through the cargo board 3 and dumps the materials into the transfer mechanism, and since the transfer mechanism includes a receiving state and an unloading state, when there are more materials in the transfer mechanism, it can switch from the receiving state to the unloading state, thereby unloading the materials in the transfer mechanism into the cargo storage bin 2; in this way, on the one hand, it saves the operation of dumping the materials into the cargo storage bin 2 every time the cargo board 3 is loaded with materials, and the materials can be dumped into the transfer mechanism for temporary storage, shortening the working stroke of the cargo board 3, thereby improving the unloading efficiency of the cargo transport device; on the other hand, when there are more materials stored in the transfer mechanism, the materials can be unloaded into the cargo storage bin 2 by switching to the unloading state, thereby reducing the bearing pressure of the transfer mechanism, increasing the amount of materials that the cargo transport device can carry in a single unloading process, and further improving the cargo transport efficiency of the cargo transport device.

[0045] As a preferred embodiment of the present application, Figure 1 、 Figure 2 、 Figure 4 As shown, as a preferred embodiment of the present application, the cargo storage bin 2 is located below the transfer mechanism, and the transfer mechanism includes a first drive component 4 and a movable cargo bin 5. The movable cargo bin 5 includes two movable bottom plates 51 connected to the first drive component 4, and the two movable bottom plates 51 have mutually abutting receiving positions and mutually separated unloading positions. The first drive component 4 can drive the two movable bottom plates 51 to switch between the receiving position and the unloading position. When the two movable bottom plates 51 are in the receiving position, the transfer mechanism is in a receiving state. When the two movable bottom plates 51 are in the unloading position, the transfer mechanism is in an unloading state. With such an arrangement, when there is a large amount of material in the transfer mechanism and it needs to be unloaded into the cargo storage bin 2, since the cargo storage bin 2 is located below the transfer mechanism, it is only necessary to drive the movable bottom plate 51 from the receiving position to the unloading position through the first drive component 4, and the material can fall into the cargo storage bin 2 below under its own weight. There is no need to set up a separate material pushing member to push the material from the movable cargo bin 5 to the cargo storage bin 2. This optimizes the structural design of the unloading device and makes the transfer of materials from the movable cargo bin 5 to the cargo storage bin 2 more convenient, reducing the difficulty of material transfer. In addition, since the number of movable bottom plates 51 is set to two, when unloading is required, the two movable bottom plates 51 move simultaneously to switch from the receiving position to the unloading position. This can reduce the movable stroke of a single movable bottom plate 51, thereby shortening the time required for the movable bottom plate 51 to switch from the receiving position to the unloading position, which helps to improve the unloading rate of the transfer mechanism.

[0046] As a preferred embodiment of this embodiment, Figure 4As shown, the first drive assembly 4 includes a first drive motor 41 and a bidirectional threaded rod 42 connected to the output shaft of the first drive motor 41, the bidirectional threaded rod 42 includes a first threaded portion 421 and a second threaded portion 422, and the thread rotation directions of the first threaded portion 421 and the second threaded portion 422 are opposite. The transfer mechanism also includes two first linking plates 52 and second linking plates 53 respectively connected to the two movable bottom plates 51, the first linking plate 52 is provided with a first rotating through hole adapted to the first threaded portion 421, and the second linking plate 53 is provided with a second rotating through hole adapted to the second threaded portion 422, the first linking plate 52 is sleeved on the first threaded portion 421 through the first rotating through hole, and the second linking plate 53 is sleeved on the second threaded portion 422 through the second rotating through hole.

[0047] Specifically, the output shaft of the first drive motor 41 can rotate in the first direction and the second direction respectively. When it rotates in the first direction, the first linkage plate 52 and the second linkage plate 53 move away from each other, thereby driving the two movable bottom plates 51 to move away from each other. When the output shaft of the first drive motor 41 rotates in the second direction, the first linkage plate 52 and the second linkage plate 53 move closer to each other, thereby driving the two movable bottom plates 51 to move closer to each other. With such an arrangement, the movable bottom plate 51 can be driven to switch between the loading position and the unloading position by the rotation of the output shaft of the first drive motor 41, so that the switching of the transfer mechanism between the loading state and the unloading state is smoother, the structural design is reasonable, and it helps to optimize the structural layout of the transfer mechanism. Preferably, the transfer mechanism includes a first supporting frame, including a frame body, and the movable bottom plate 51 is located at the bottom of the frame body and can only move in the horizontal direction under the restriction of the frame body. In this way, when the bidirectional threaded rod 42 rotates, the movable bottom plate 51 and the first linkage plate 52 and the second linkage plate 53 connected to the movable bottom plate 51 can only move in the horizontal direction and will not rotate synchronously with the rotation of the bidirectional threaded rod 42.

[0048] As a preferred embodiment of the present application, Figure 1 、 Figure 2As shown, the cargo storage bin 2 is located below the transfer mechanism and further includes a lifting assembly 6, which can drive the lifting unit to move in the vertical direction so as to approach or move away from the cargo storage bin 2. By providing the lifting assembly 6 and driving the lifting assembly 6 to move in the vertical direction, when the material in the transfer mechanism needs to be delivered to the finished cargo bin, the transfer mechanism can be driven by the lifting assembly 6 to descend in the vertical direction to approach the cargo storage bin 2, so that the material can be transferred from the transfer mechanism to the cargo storage bin 2 when the distance between the transfer mechanism and the cargo storage bin 2 is relatively close, thereby reducing the risk of material damage caused by a long falling distance during the material falling process, and providing protection for the integrity of the material. In addition, since the materials are placed at different heights and positions, it is necessary to adjust the height of the cargo board 3 in order to obtain materials at different heights. The lifting component 6 can simultaneously drive the cargo transport mechanism to achieve vertical displacement, so that the lifting component 6 not only has the function of adjusting the vertical height of the transfer mechanism to facilitate the transfer of materials from the transfer mechanism to the cargo storage warehouse 2, but also further integrates the function of adjusting the position of the cargo mechanism to facilitate the cargo board 3 to obtain materials. The functions are further integrated, which reduces the difficulty of the cargo board 3 to obtain materials and improves the adaptability of the cargo transport device to goods of different heights.

[0049] As another preferred embodiment under this embodiment, Figure 3 As shown, the lifting assembly 6 includes a second drive motor 61 and a one-way threaded rod 62 connected to the output shaft of the second drive motor 61, the one-way threaded rod 62 extends in the vertical direction, and the transfer mechanism includes a third linkage plate 7, the third linkage plate 7 is provided with a third rotating through hole adapted to the one-way threaded rod 62, the transfer mechanism is installed on the one-way threaded rod 62 through the third linkage plate 7, the second drive motor 61 can drive the one-way threaded rod 62 to rotate, so that the third linkage plate 7 drives the transfer mechanism to move in the vertical direction.

[0050] By setting up a lifting component 6 and driving the transfer mechanism to move in the vertical direction, when the material in the transfer mechanism needs to be sent to the finished goods warehouse, the lifting component 6 can drive the transfer mechanism to descend in the vertical direction to approach the goods warehouse 2, so that the material can be transferred from the transfer mechanism to the goods warehouse 2 when the distance between the transfer mechanism and the goods warehouse 2 is closer, reducing the risk of material damage caused by a long falling distance during the falling process, and providing protection for the integrity of the material.

[0051] As a preferred example under this embodiment, Figure 1As shown, the mounting frame 1 includes a top plate 11, a back plate 12 and a base 13. The back plate 12 is connected to the top plate 11 and the base 13 respectively. The cargo bin 2 is installed on the base 13. The one-way threaded rod 62 passes through the base 13 and the top plate 11 in sequence. The back plate 12 is provided with a guide rail 14 extending in a vertical direction. The transfer mechanism also includes a guide groove adapted to the guide rail 14.

[0052] By setting up the base 13, on the one hand, a mounting position is provided for the cargo bin 2, and on the other hand, the base 13 cooperates with the top plate 11 to fix the one-way threaded rod 62, so that the function of the base 13 is further integrated; in addition, in addition to the role of connecting the top plate 11 and the base 13, the back plate 12 also plays the role of taking on the guide rail 14. By setting up the guide rail 14 and the guide groove, the movement direction of the transfer mechanism is limited, and a guiding effect is provided for the movement of the transfer mechanism in the vertical direction, thereby reducing the probability of the transfer mechanism being displaced during movement, and avoiding the synchronous rotation of the transfer mechanism with the rotation of the one-way threaded rod 62.

[0053] Specifically, the base 13 includes an upper base 131 and a lower base 132 . The lower base 132 is used to support the cargo bin 2 and the second driving motor 61 . The one-way threaded rod 62 is passed through the upper base 131 .

[0054] As a preferred embodiment of the present application, Figure 4 As shown, the cargo transport mechanism includes a second drive assembly, which includes a third drive motor 110. The third drive motor 110 includes a third output shaft. The cargo plate 3 is mounted on the third output shaft. The third drive motor 110 drives the third output shaft to rotate, thereby driving the cargo plate 3 to rotate. The third output shaft driven by the third drive motor 110 drives the cargo plate 3 to rotate synchronously, thereby adjusting the position of the cargo plate 3. This helps to quickly adjust the position and angle of the cargo plate 3 according to the needs of material placement, making it easier for the cargo plate 3 to be inserted into the bottom of the cargo to achieve lifting and transportation of the materials. When the materials on the cargo plate 3 need to be transferred to the transfer mechanism, it is only necessary to control the drive motor to rotate the third output shaft to tilt the cargo plate 3 toward the transfer mechanism to achieve the dumping of the materials into the transfer mechanism, thereby improving the efficiency of material transfer.

[0055] As a preferred embodiment of this embodiment, Figure 1As shown, a rotating roller 8 is sleeved on the outer side of the third output shaft, and a connecting block 33 is provided at the bottom of the cargo plate 3. The connecting block 33 is fixedly connected to the rotating roller 8. The provision of the rotating roller 8 and the connecting block 33 increases the contact area between the cargo plate 3 and the third output shaft, thereby increasing the installation stability of the cargo plate 3 and reducing the occurrence of unstable material transportation caused by an unstable connection between the cargo plate 3 and the third output shaft when carrying materials.

[0056] Preferably, the rotating roller 8 is made of metal material, the connecting block 33 is made of metal material, and the cargo plate 3 is made of metal material. The rotating roller 8 and the connecting block 33, and the connecting block 33 and the cargo plate 3 are connected by welding.

[0057] As a preferred embodiment of the present application, Figure 1 、 Figure 2 As shown, the pallet 3 includes a load-bearing portion 31 for carrying cargo, and an insertion portion 32 located at the end of the load-bearing portion 31. The insertion portion 32 has a sharp insertion corner 321 on the side facing away from the load-bearing portion 31. Due to the placement or stacking of materials, materials are usually stacked closely together. The provision of the sharp insertion corner 321 allows the pallet 3 to more easily insert under the materials and support them, thereby achieving lifting and transport of the materials.

[0058] As a preferred embodiment of the present application, Figure 1 As shown, the bottom of the mounting frame 1 is provided with a plurality of self-locking steering wheels 9, and the mounting frame 1 is also equipped with a handrail 10. The provision of the handrail 10 and the self-locking universal wheels facilitates the transfer of materials. Workers can push the cargo transport device by holding the handrail 10 to achieve rapid transfer of materials. When the cargo transport board 3 is transporting materials to the transfer mechanism, the cargo transport device needs to remain stable. At this time, the self-locking universal wheels can lock its rotation direction, thereby maintaining the stability of the cargo transport device and providing a stable working platform for the cargo transport board 3.

[0059] Specifically, the working process of the cargo transport device of the present application is as follows: the staff pushes the cargo transport device to the unloading location through the handrail 10, drives the third output shaft to rotate through the third drive motor 110, and adjusts the inclination angle of the cargo plate 3 on the third output shaft according to the placement angle of the material. Taking the bottom plate of the material as an example, the cargo plate 3 is adjusted to the horizontal level, and the vertical height of the cargo plate 3 is adjusted by the lifting component 6 so that the insertion corner 321 of the cargo plate 3 is facing the bottom of the material, and then the cargo transport device is pushed by the handrail 10 to move towards the material until the cargo is transported. Plate 3 is inserted into the bottom of the material and completes the support of the material. The inclination angle of the transport plate 3 is adjusted by rotating the third output shaft. The material slides on the transport plate 3 under the action of its own weight and falls into the transfer mechanism. When the material is poured into the transfer mechanism many times and there is a lot of material in the transfer mechanism, the transfer mechanism is controlled to descend by the lifting component 6, and the transfer mechanism switches from the loading state to the unloading state. The material in the transfer mechanism slides into the cargo bin 2 under the action of its own weight. This is repeated many times until the cargo bin 2 is filled with materials. The staff pushes the transport device to the warehouse to unload the materials through the handrail 10.

[0060] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0061] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

For those skilled in the art, the present application may have various changes and variations.
