Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and more specifically, to a cross-ground conveying device. Background Technology

[0002] Currently, in automated production, it is often necessary to transport materials or products over long distances. However, due to the limitations of site area and production line layout, when transporting materials or products over long distances across multiple workstations, additional staff are required for transfer and transport. Since the production site is usually quite compact, it is very inconvenient for staff to move back and forth in the narrow space to transport materials, resulting in low work efficiency and easy interference with the normal work of other staff, thus affecting production efficiency. Utility Model Content

[0003] In view of this, the present invention provides a cross-ground conveying device to solve the problems existing in the background art.

[0004] The objective of this utility model is achieved through the following technical solution. A cross-ground conveying device includes a frame, and mounted on the frame: a loading module including a loading platform and a loading lifting mechanism, the loading lifting mechanism being used to drive the loading platform to move up and down; a unloading module including a unloading platform and a unloading lifting mechanism, the unloading lifting mechanism being used to drive the unloading platform to move up and down; an aerial conveying module disposed between the loading module and the unloading module, the aerial conveying module including a conveying slide rail, the conveying slide rail being inclined; and a blocking module installed at one end of the conveying slide rail near the unloading module, the blocking module including a first blocking frame, a second blocking frame and a driving lever, the first blocking frame and the second blocking frame slidingly passing through the conveying slide rail in a vertical direction, the driving lever being able to drive the first blocking frame and the second blocking frame to move in opposite directions by rotation.

[0005] In the above scheme, both the loading platform and the unloading platform are slidably mounted on the frame. During operation, the material to be transported is first placed on the loading platform, and the loading lifting mechanism raises the platform to one side of the conveyor rail. Then, the material is moved onto the conveyor rail. Since the conveyor rail is inclined, tilting downwards from the loading module side towards the unloading module side, the material can slide along the conveyor rail towards the unloading module by its own weight. A blocking module is provided at the end of the conveyor rail near the unloading module. The first blocking frame is located near the unloading module. The first and second blocking frames can extend or retract from the conveyor rail under the drive of a drive lever, and their directions of movement are opposite. Initially, the drive lever... One end of the lever lifts the first blocking frame, causing it to extend from the conveyor rail. The other end of the drive lever lowers the second blocking frame, causing it to retract under the conveyor rail. At this time, the extended first blocking frame can block the material on the conveyor rail, keeping it on the rail. When the unloading platform is raised to one side of the conveyor rail by the unloading lifting mechanism, the drive lever is rotated again to lower the first blocking frame under the conveyor rail. The material then slides onto the unloading platform under its own weight, while the second blocking frame extends from the conveyor rail to block the material behind it, achieving orderly unloading. Subsequently, the unloading platform is lowered, and the staff can remove the material, thus completing the cross-ground material transport.

[0006] In one example of this utility model, the blocking module further includes a rotating lever, which is configured to be rotatable. One end of the rotating lever extends into the movement path of the unloading platform, and the other end can apply force to the driving lever to drive the driving lever to rotate.

[0007] In the above scheme, the rotating lever is rotatably mounted on the frame, with one end located on the moving path of the unloading platform. When the unloading platform rises, it pushes the rotating lever to make it rotate, and the other end of the rotating lever drives the drive lever to rotate, forming a lever-like structure. This lowers the first blocking frame to remove the obstruction to the material on the conveyor rail, allowing the material to move from the conveyor rail to the unloading platform, thus realizing the unloading of the material.

[0008] In one example of this invention, a counterweight is mounted on the drive lever.

[0009] In the above scheme, the counterweight is installed at the end of the drive lever away from the first blocking frame, so that the drive lever maintains the tilted state of lifting the first blocking frame when it does not receive the force of the rotating lever, so as to ensure the blocking effect on the material and prevent the material from falling out.

[0010] In one example of this utility model, the loading platform includes a loading slide rail, and the loading slide rail has the same inclination angle as the conveying slide rail.

[0011] In the above scheme, the tilt angle of the feeding slide rail is the same as that of the conveying slide rail, so that the material can slide from the feeding platform onto the conveying slide rail.

[0012] In one example of this utility model, the loading platform is provided with a loading stop bar, which is slidably installed at one end of the loading slide rail in the vertical direction, and the aerial conveying module is provided with a top block on the side near the loading module.

[0013] In the above scheme, since the feeding slide rail is inclined, the feeding stop is used to block and limit the placed material. When the feeding platform is raised to one side of the conveying slide rail, the top block contacts the feeding stop and presses the feeding stop under the feeding slide rail. At this time, the material is not blocked and automatically slides onto the conveying slide rail under its own weight, thus realizing the feeding of the material.

[0014] In one example of this utility model, the feeding lifting mechanism includes a first fixed pulley and a first movable pulley. The feeding platform, the first fixed pulley, and the first movable pulley are connected by a pull rope. The pull rope is wound around the first fixed pulley and the first movable pulley, and both ends of the pull rope are connected to the feeding platform.

[0015] In the above scheme, the first fixed pulley is located above the loading platform and the first movable pulley. The two ends of the rope are connected to the loading platform, and the rest is wrapped around the first fixed pulley and the first movable pulley. When the loading platform needs to be raised, a vertical downward force is applied to the first movable pulley, so that the rope is pulled downward. The downward force is changed in direction by the first fixed pulley and becomes an upward force on the loading platform, thereby pulling the loading platform up. When the loading platform needs to be lowered, simply stop applying force to the first movable pulley. The loading platform moves down under the action of gravity, generating a downward force. The first fixed pulley changes in direction and becomes an upward force on the first movable pulley, so that the first movable pulley rises and resets.

[0016] In one example of this utility model, the feeding lifting mechanism further includes a feeding step bar and a first mounting frame. The first mounting frame is slidably mounted on the frame, and the first movable pulley is mounted on the first mounting frame. One end of the feeding step bar is rotatably mounted on the frame. The feeding step bar can apply force to the first mounting frame by rotating to drive the first mounting frame to move.

[0017] In the above scheme, the first movable pulley can move up and down through the first mounting frame, and the feeding step bar is movably installed through the first mounting frame. When it is necessary to raise the feeding platform, the feeding step bar is stepped on at the end away from the end that is rotatably connected to the frame, causing the feeding step bar to rotate. The feeding step bar drives the first mounting frame and the first movable pulley to move downward, thereby raising the feeding platform. After releasing the feeding step bar, the feeding platform descends under the action of gravity, driving the first mounting frame and the first movable pulley to rise and reset.

[0018] In one example of this utility model, the unloading platform includes an unloading slide rail, and the unloading slide rail has the same inclination angle as the conveying slide rail.

[0019] In the above scheme, the inclination angle of the unloading slide rail is the same as that of the conveying slide rail, so that the material can slide from the conveying slide rail onto the unloading platform.

[0020] In one example of this utility model, the material unloading lifting mechanism includes a second fixed pulley and a second movable pulley. The unloading platform, the second fixed pulley, and the second movable pulley are connected by a pull rope. The pull rope is wound around the second fixed pulley and the second movable pulley, and both ends of the pull rope are connected to the unloading platform.

[0021] In the above scheme, the second fixed pulley is located above the unloading platform and the second movable pulley. The two ends of the pull rope are connected to the unloading platform, and the rest is wrapped around the second fixed pulley and the second movable pulley. When it is necessary to raise the unloading platform, a vertical downward force is applied to the second movable pulley, so that the pull rope is subjected to a downward pull. The downward pull is changed in direction by the second fixed pulley and becomes an upward pull on the unloading platform, thereby pulling the unloading platform up. When it is necessary to lower the unloading platform, simply stop applying force to the second movable pulley. The unloading platform moves down under the action of gravity, generating a downward pull. The second fixed pulley changes in direction and becomes an upward pull on the second movable pulley, so that the second movable pulley rises and resets.

[0022] In one example of this utility model, the material feeding lifting mechanism further includes a material feeding pedal and a second mounting frame. The second mounting frame is slidably mounted on the frame, and the second movable pulley is mounted on the second mounting frame. One end of the material feeding pedal is rotatably mounted on the frame. The material feeding pedal can apply force to the second mounting frame by rotating, thereby driving the second mounting frame to move.

[0023] In the above scheme, the second movable pulley can move up and down through the second mounting frame, and the unloading pedal rod is movably installed through the second mounting frame. When it is necessary to raise the unloading platform, the unloading pedal rod is stepped on to the end that is rotatably connected to the frame, causing the unloading pedal rod to rotate. The unloading pedal rod drives the second mounting frame and the second movable pulley to move downward, thereby raising the unloading platform. After releasing the unloading pedal rod, the unloading platform descends under the action of gravity, driving the second mounting frame and the second movable pulley to rise and reset.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables long-distance aerial transport of materials without the need for a power unit, offering good economic efficiency and a small footprint. It effectively meets the transportation needs of various production scenarios. Furthermore, this invention is easy to operate and highly efficient, making it suitable for widespread use. This utility model is equipped with a blocking module, which can block the material on the conveyor slide rail to ensure that the material is fed out only after the unloading platform rises to a suitable height, thus preventing the material from falling out. It has high safety and reliability. In particular, by moving the lever assembly, the first blocking frame and the second blocking frame can move in opposite directions, which can allow the material in front to pass while blocking the material behind, so as to achieve orderly feeding.

Detailed Implementation

[0039] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0040] Please refer to Figures 1 to 3 In a preferred embodiment of this utility model, a cross-ground conveying device is provided, including a frame 1, and a loading module 2, an aerial conveying module 3, a blocking module 4, and a unloading module 5 disposed on the frame 1. The loading module 2 includes a loading platform 21 and a loading lifting mechanism, which drives the loading platform 21 to rise and fall; the unloading module 5 includes a unloading platform 51 and a unloading lifting mechanism, which drives the unloading platform 51 to rise and fall; the aerial conveying module 3 is disposed between the loading module 2 and the unloading module 5, and includes a conveying slide rail 31, which is inclined; the blocking module 4 is installed at one end of the conveying slide rail 31 near the unloading module 5, and includes a first blocking frame 41, a second blocking frame 42, and a driving lever 43. The first blocking frame 41 and the second blocking frame 42 slide vertically through the conveying slide rail 31, and the driving lever 43 can drive the first blocking frame 41 and the second blocking frame 42 to move in opposite directions by rotation.

[0041] Specifically, both the loading platform 21 and the unloading platform 51 are slidably mounted on the frame 1 and can slide up and down. When conveying materials, the materials are first placed on the loading platform 21, and the loading lifting mechanism lifts the loading platform 21 to one side of the conveying slide rail 31. Then the materials move onto the conveying slide rail 31. Since the conveying slide rail 31 is inclined, the materials can slide towards the unloading module 5 on the conveying slide rail 31 by their own weight. A blocking module 4 is provided at one end of the conveying slide rail 31 near the unloading module 5. The first blocking frame 41 is located on the side near the unloading module 5. When the drive lever 43 rotates, its two ends can apply force to the first blocking frame 41 and the second blocking frame 42 respectively, causing the first blocking frame 41 and the second blocking frame 42 to extend or retract from the conveying slide rail 31. In the initial state, one end of the drive lever 43 blocks the first blocking frame 41. The first blocking frame 41 is raised, causing it to extend from the conveyor rail 31. The other end of the drive lever 43 presses down the second blocking frame 42, causing it to retract under the conveyor rail 31. At this time, the extended first blocking frame 41 can block the material on the conveyor rail 31, keeping it on the conveyor rail 31. When the unloading platform 51 is raised to one side of the conveyor rail 31 by the unloading lifting mechanism, the drive lever 43 is rotated again, pressing the first blocking frame 41 down under the conveyor rail 31. At this time, the material slides onto the unloading platform 51 under its own weight, while the second blocking frame 42 extends from the conveyor rail 31 to block the material behind, achieving orderly unloading. After the material slides onto the unloading platform 51, the unloading platform 51 is lowered, and the material is removed by the staff, thus completing the cross-ground transport of the material.

[0042] It is understandable that since loading materials into the aerial conveyor module 3 requires the lifting and lowering of the loading platform 21, this process takes a certain amount of time. Therefore, there will be a certain gap between the materials in front and behind on the conveyor rail 31. In this way, when the first blocking frame 41 releases the materials, the second blocking frame 42 can block the materials behind.

[0043] It should be noted that, as Figure 5 As shown, the conveyor rail 31 consists of three parallel flow bars 311, which are spaced apart. A first blocking frame 41 and a second blocking frame 42 are slidably mounted on the frame 1 and can move up and down. Both the first blocking frame 41 and the second blocking frame 42 have two vertically arranged rods that can pass through the gaps between the flow bars 311 to block material on the conveyor rail 31. The flow bars 311 are commonly used in this field, and their specific structure and principle will not be elaborated upon here.

[0044] The blocking module 4 also includes a rotating lever 44. Both the drive lever 43 and the rotating lever 44 are rotatably mounted on the frame 1. Figure 2 and Figure 3As shown, the drive lever 43 can rotate around the first rotation fulcrum 46a, and the rotation lever 44 can rotate around the second rotation fulcrum 46b. The right end of the rotation lever 44 extends into the movement path of the unloading table 51, and the left end can apply force to the drive lever 43 to drive the drive lever 43 to rotate.

[0045] Specifically, refer to Figures 1 to 3 As shown, when the feeding platform 51 rises, the left side of the feeding platform 51 can push the right end of the rotating lever 44, causing the rotating lever 44 to rotate counterclockwise. At this time, the left end of the rotating lever 44 applies force to the drive lever 43, causing the drive lever 43 to rotate clockwise. The right end of the drive lever 43 drives the first blocking frame 41 to move down, thereby removing the obstruction of the material. At the same time, the left end of the drive lever 43 drives the second blocking frame 42 to move up, thereby blocking the material behind when the material is released for feeding. When the first blocking frame 41 moves down below the conveyor rail 31, the material slides from the conveyor rail 31 onto the feeding platform 51 under its own weight. Thus, the material is automatically fed when the feeding platform 51 rises to a suitable height, making the operation more convenient and preventing the material from falling out before the feeding platform 51 has moved to the appropriate position, thus improving safety.

[0046] Furthermore, a counterweight 45 is installed on the drive lever 43. The counterweight 45 is installed at the end of the drive lever 43 away from the first blocking frame 41 (i.e., the left end in the figure). After the material is released for feeding, the rotating lever 44 no longer applies force to the drive lever 43. Under the gravity of the counterweight 45, the drive lever 43 rotates counterclockwise to reset. The right end of the drive lever 43 lifts the first blocking frame 41 again, so that it extends onto the conveying slide rail 31, thereby continuing to maintain the tilted state of lifting the first blocking frame 41 to ensure the blocking effect on the material.

[0047] It should be noted that, in order to reduce operating costs, this embodiment uses a rotating lever 44 and a driving lever 43 to achieve automatic blocking and feeding of materials using the lever principle, eliminating the need for a power unit and thus avoiding electricity or other energy consumption. Alternatively, in other embodiments, a separate drive motor can be used to rotate the driving lever 43, or independent drive components can be provided for the first blocking frame 41 and the second blocking frame 42 to drive them up and down, achieving the same technical effect as this embodiment.

[0048] Please refer to Figures 4 to 7 The loading platform 21 includes a loading slide rail 211, which has the same inclination angle as the conveying slide rail 31, so that the material can slide from the loading platform 21 onto the conveying slide rail 31. The loading platform 21 is provided with a loading stop bar 212, which is installed on the end of the loading slide rail 211 near the conveying slide rail 31 and can slide up and down. The overhead conveying module 3 is provided with a top block 32 on the side near the loading module 2.

[0049] like Figure 5 and Figure 7 As shown, since the feeding slide rail 211 is inclined, the feeding stop bar 212 is used to block and limit the material placed on the feeding slide rail 211. The feeding stop bar 212 can slide vertically. When the feeding platform 21 is raised to one side of the conveying slide rail 31, the top block 32 can contact the feeding stop bar 212 and press the feeding stop bar 212 down below the feeding slide rail 211. At this time, the material is not blocked and can automatically slide onto the conveying slide rail 31 under its own weight, thereby realizing the automatic feeding of the material.

[0050] It should be noted that an elastic element (not shown in the figure) is provided at the connection between the feeding stop bar 212 and the feeding platform 21. When the top block 32 presses down the feeding stop bar 212, the elastic element is compressed by force. When the top block 32 separates from the feeding stop bar 212, the feeding stop bar 212 can be reset under the action of the elastic element.

[0051] Preferably, the feeding slide rail 211 consists of three parallel flow bars, which are spaced apart and correspond to the conveying slide rail 31.

[0052] Preferably, the feeding stop bar 212 has a U-shaped structure, and the two parallel side bars of the feeding stop bar 212 are used to block the material.

[0053] Please refer to Figures 4 to 9 The feeding lifting mechanism includes a first fixed pulley 22, a first movable pulley 23, a feeding step bar 24, and a first mounting frame 25. The feeding platform 21, the first fixed pulley 22, and the first movable pulley 23 are connected by a pull rope. Multiple first fixed pulleys 22 and first movable pulleys 23 are provided. The two ends of the first mounting frame 25 are slidably mounted on the frame 1 through first sliding mounting parts 251, and can slide up and down on the frame 1. The first movable pulley 23 is mounted on the first mounting frame 25. One end of the feeding step bar 24 is rotatably mounted on the first mounting shaft 11 of the frame 1, and the feeding step bar 24 can rotate around the axis of the first mounting shaft 11.

[0054] The two ends of the pull rope are connected to the loading platform 21, and the rest is wrapped around the first fixed pulley 22 and the first movable pulley 23. The loading step bar 24 is movably inserted through the first mounting frame 25, so that it can drive the first mounting frame 25 to move when rotating.

[0055] In specific operation, when it is necessary to raise the loading platform 21, the loading step bar 24 is stepped on, causing the loading step bar 24 to rotate around the first mounting shaft 11. The loading step bar 24 drives the first mounting frame 25 and the first movable pulley 23 on it to move downward, so that the pull rope is subjected to a downward pulling force. After the downward pulling force is changed in direction by the two first fixed pulleys 22 above the loading platform 21, it becomes an upward pulling force on the loading platform 21, thereby pulling the loading platform 21 upward. After releasing the loading step bar 24, the loading platform 21 moves downward under the action of gravity, generating a downward pulling force. After the first fixed pulley 22 is changed in direction, it becomes an upward pulling force on the first mounting frame 25 and the first movable pulley 23, thereby causing the first mounting frame 25 and the first movable pulley 23 to rise and return to the initial state.

[0056] Understandably, at least two first fixed pulleys 22 are located above the loading platform 21, thereby converting the downward force on the first mounting frame 25 into an upward pulling force on the loading platform 21. The remaining first fixed pulleys 22 are used to guide the pull rope, such as... Figure 9 As shown, below the loading platform 21, a first fixed pulley 22 is provided above each first movable pulley 23 to guide the pull rope, so that the pull rope connects the multiple first movable pulleys 23 on the first mounting frame 25 together.

[0057] Preferably, the end of the feeding foot pedal 24 away from the first mounting shaft 11 is provided with a feeding foot frame 241 to facilitate the worker to step on it and apply force.

[0058] The number of the first fixed pulley 22 and the first movable pulley 23 is not limited and can be adjusted according to actual needs.

[0059] Please refer to Figures 10 to 12 The unloading platform 51 includes an unloading slide rail 511, which has the same inclination angle as the conveying slide rail 31, so that the material can slide from the conveying slide rail 31 onto the unloading platform 51.

[0060] Preferably, the feeding slide rail 511 consists of two parallel flow bars, which are spaced apart.

[0061] Preferably, such as Figure 11 As shown, a baffle 512 is provided at the end of the unloading platform 51 away from the conveyor rail 31 to block the material moving onto the unloading platform 51.

[0062] Please continue to refer to Figures 10 to 12The material unloading lifting mechanism includes a second fixed pulley 52, a second movable pulley 53, a material unloading pedal 54, and a second mounting frame 55. The unloading platform 51, the second fixed pulley 52, and the second movable pulley 53 are connected by a pull rope. Multiple second fixed pulleys 52 and multiple second movable pulleys 53 are provided. The two ends of the second mounting frame 55 are slidably mounted on the frame 1 through second sliding mounting parts 551, and can slide up and down on the frame 1. The second movable pulley 53 is mounted on the second mounting frame 55. One end of the material unloading pedal 54 is rotatably mounted on the second mounting shaft 12 of the frame 1, and the material unloading pedal 54 can rotate around the axis of the second mounting shaft 12.

[0063] Similar to the loading and lifting mechanism, the two ends of the pull rope are connected to the unloading platform 51, and the rest is wrapped around the second fixed pulley 52 and the second movable pulley 53. The unloading step bar 54 is movably inserted through the second mounting frame 55, so that it can drive the second mounting frame 55 to move when rotating. In specific operation, when it is necessary to raise the unloading platform 51, the unloading pedal 54 is stepped on, causing the unloading pedal 54 to rotate around the second mounting shaft 12. The unloading pedal 54 drives the second mounting frame 55 and the second movable pulley 53 on it to move downward, so that the pull rope is subjected to a downward pulling force. After the downward pulling force is changed in direction by the two second fixed pulleys 52 above the unloading platform 51, it becomes an upward pulling force on the unloading platform 51, thereby pulling the unloading platform 51 upward. After releasing the unloading pedal 54, the unloading platform 51 moves downward under the action of gravity, generating a downward pulling force. After the second fixed pulley 52 is changed in direction, it becomes an upward pulling force on the second mounting frame 55 and the second movable pulley 53, thereby causing the second mounting frame 55 and the second movable pulley 53 to rise and return to the initial state.

[0064] Understandably, similar to the loading and lifting mechanism, at least two second fixed pulleys 52 are located above the unloading platform 51, thereby converting the downward force on the second mounting bracket 55 into an upward pulling force on the unloading platform 51. The remaining second fixed pulleys 52 are used to guide the pull rope, such as... Figure 12 As shown, below the unloading platform 51 and above the second movable pulley 53, there are multiple second fixed pulleys 52 to guide the pull rope, so that the pull rope connects the multiple second movable pulleys 53 on the second mounting frame 55 together.

[0065] Preferably, the end of the material feeding pedal 54 away from the second mounting shaft 12 is provided with a material feeding pedal frame 541 to facilitate the worker to step on it and apply force.

[0066] The number of the second fixed pulley 52 and the second movable pulley 53 is not limited and can be adjusted according to actual needs.

[0067] It is worth mentioning that the loading and unloading lifting mechanisms utilize the lever principle and pulley system to achieve cross-ground material transport without the need for a power unit. During use, no electricity or other energy consumption is generated, achieving zero operating costs and offering better economy and practicality.

[0068] In other embodiments, a separate drive device can be provided for the first mounting frame 25 and the second mounting frame 55 to drive the first mounting frame 25 and the second mounting frame 55 to move up and down, so as to replace the loading step bar 24 and the unloading step bar 54, and also realize the lifting movement of the loading platform 21 and the unloading platform 51.

[0069] Please refer to the diagram. Taking the conveying of a single material as an example, the specific working steps and principles are as follows: First, the material to be transported is placed on the loading platform 21, and the loading baffle 212 blocks the material. Then, the loading step bar 24 is stepped on, causing the first mounting frame 25 and its first movable pulley 23 to descend. Under the traction of the pull rope, the loading platform 21 rises. When the loading platform 21 rises to the height of one side of the conveyor rail 31, the top block 32 contacts the loading baffle 212, pressing it down. Then, the material slides onto the conveyor rail 31 under its own weight and continues to slide along the conveyor rail 31 to the position of the first blocking frame 41, where the first blocking frame 41 blocks the material. Finally, the material is unloaded by stepping on the step bar. Stepping on the lever 54 causes the second mounting frame 55 and its second movable pulley 53 to descend. Under the traction of the pull rope, the unloading platform 51 rises. When the unloading platform 51 rises to the height of one side of the conveyor rail 31, the unloading platform 51 contacts the rotating lever 44, causing the rotating lever 44 to rotate. The rotating lever 44 then drives the drive lever 43 to rotate, causing the first mounting frame 25 to move down. At this time, the material slides onto the unloading platform 51 under its own weight. The baffle 512 on the unloading platform 51 blocks the material. Then, the unloading stepping lever 54 is released, and the unloading platform 51 descends, allowing the staff to remove the material from the unloading platform 51.
