Description

Technical Field

[0001] This invention relates to the field of loading platform technology, and more particularly to a bulk cargo loading platform. Background Technology

[0002] Loading platforms are used to transfer goods into containers. Conventional loading platforms are usually used to transfer goods with regular shapes. First, the goods are moved to the transport rails of the loading platform by forklifts and stacked. Then, the transport rails carry the goods into the container. The stacked goods can enter the container neatly. However, when transferring bulk goods, because of their irregular shapes, they cannot be stacked. When they enter the container with the transport rails, the goods will scatter everywhere, resulting in messy goods and occupying more space. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that when bulk cargo is transferred, it cannot be stacked due to its irregular shape, and when it enters the container with the conveyor track, the cargo will be scattered everywhere, resulting in messy cargo and occupying a lot of space. The present invention provides a bulk cargo loading platform.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bulk cargo loading platform includes a conveying track, a gantry that can move along the cargo conveying direction is provided on the conveying track, a curtain assembly is installed on the gantry, the curtain assembly includes a lifting mechanism and a retractable curtain body, a first clamping mechanism for clamping the curtain body is provided at the bottom of the lifting mechanism body, and a second clamping mechanism for clamping the curtain body is provided at the front end of the conveying track.

[0005] In the initial state, the front end of the curtain body is fixed on the first clamping mechanism and can be raised and lowered synchronously with the lifting mechanism. When the gantry moves to the front end of the conveying track, the first clamping mechanism drives the curtain body to move downward and switches to the second clamping mechanism to clamp the curtain body. Then the curtain assembly moves upward and the gantry moves to the rear end of the conveying track while driving the curtain body to unroll and cover the goods on the conveying track.

[0006] The above technical solution utilizes a gantry to move the curtain body to the front end of the conveying track. The first clamping mechanism moves the curtain body downward and switches to the second clamping mechanism to clamp the curtain body. Then, the gantry moves the curtain body to the rear end of the conveying track to cover the goods on the conveying track, thereby tightly wrapping the bulk goods inside the curtain body, making them a whole before conveying them into the container, making the entire conveying process neat and orderly.

[0007] Furthermore, the curtain assembly is located at the front end of the mast along its moving direction, and the curtain assembly is provided at the rear end of the mast. The curtain assembly includes a telescopic mechanism and a curtain body installed on the telescopic mechanism. The mast has protective covers at both ends perpendicular to the cargo conveying direction. The protective covers, the curtain assembly, and the curtain assembly can form a cavity to accommodate the cargo. First, the lifting mechanism drives the curtain body to move down, and the telescopic mechanism drives the curtain body to move up. The forklift transports the bulk cargo into the cavity of the mast. After the transport is completed, the telescopic mechanism drives the curtain body to move down, and the curtain assembly and the curtain assembly surround the cargo between them. Then, the mast and the cargo move forward synchronously. After reaching the designated position, the lifting mechanism drives the curtain body to move up, and the telescopic mechanism drives the curtain body to move up. The mast moves backward over the cargo to transport the next batch of cargo.

[0008] Furthermore, the first clamping mechanism includes a pushing cylinder and a pushing groove. The output end of the pushing cylinder extends into the pushing groove to press the curtain body between its output end and the groove wall. In the initial state, the output end of the pushing cylinder extends to press the curtain body onto the groove wall, thereby clamping the curtain body. When the gantry moves to the front end of the conveying track, the curtain assembly drives the curtain body to move downward to the second clamping mechanism. Then, the output end of the pushing cylinder retracts, and the second clamping mechanism is activated to clamp the curtain body.

[0009] Furthermore, the second clamping mechanism includes a clamping cylinder and a clamping rod. The clamping rod is bent into a U-shaped structure, and a pressure block is slidably connected to the clamping rod. The pressure block and the clamping rod enclose a clamping cavity for clamping the curtain body. The clamping cylinder is used to drive the pressure block to slide on the clamping rod to control the size of the clamping cavity, thereby realizing the clamping and releasing of the curtain body.

[0010] Furthermore, both the lifting mechanism and the telescopic mechanism include an upper support, a lower support, and a scissor bracing mechanism located between them. The scissor bracing mechanism includes several pairs of arms distributed vertically. Adjacent pairs of arms in the middle are hinged to form two hinge points. One of the two hinge points is fixed to the crossbar, and the other hinge point is slidably connected to a groove on the crossbar. A first drive mechanism for driving the opening and closing of the scissor bracing mechanism is installed on the top of the upper support. The first drive mechanism includes a first motor, the output end of which is connected to a first lead screw. A first nut seat is threaded onto the first lead screw. One of the two arms at the top of the scissor bracing mechanism is hinged to the upper support, and the other arm is hinged to the first nut seat. A groove is also provided on the lower support. One of the two arms at the bottom of the scissor bracing mechanism is hinged to the lower support, and the other arm is slidably connected to the groove on the lower support. When the first motor is started, the first lead screw rotates, causing the first nut seat to move, thereby driving the scissor bracing mechanism to open and close, realizing the lifting of the lifting mechanism or the telescopic extension of the telescopic component.

[0011] Furthermore, the curtain assembly and the door curtain assembly can be close to or far from each other, and the distance between the curtain assembly and the door curtain assembly can be controlled according to the volume of the goods.

[0012] Furthermore, a second drive mechanism for driving the curtain assembly to move along the cargo conveying direction is installed on the top of the curtain assembly. The second drive mechanism includes a second motor, and the output end of the second motor is connected to a second lead screw. A second nut seat is threaded onto the second lead screw. The second nut seat is fixed to the top of the curtain assembly, and a slide rail is provided on the door frame. A slider that cooperates with the slide rail is provided on the top of the curtain assembly.

[0013] Furthermore, a third drive mechanism is installed at the bottom of the gantry to drive its reciprocating motion. The third drive mechanism includes a third motor, a gear fixed on the output end of the third motor, and a rack on the conveying track. The gear meshes with the rack. There are two sets of the third drive mechanism, located on both sides of the gantry. Rollers are installed at the bottom of the gantry, and guide rails are installed on the conveying track. When the third motor is started, it drives the gear to rotate on the rack, thereby realizing the reciprocating movement of the gantry.

[0014] Furthermore, the conveying track includes two parallel conveying lines, which can be close to or far from each other. Each conveying line is equipped with the aforementioned gantry, and the two gantry can also be close to or far from each other.

[0015] Furthermore, baffles are provided on both sides of the conveying track to prevent goods from falling off the conveying track. Rollers are installed on the baffles to reduce the friction between the baffles and the goods.

[0016] The beneficial effects of the present invention are as follows: The present invention utilizes a gantry to move the curtain body to the front end of the conveying track. The first clamping mechanism moves the curtain body downward and switches to the second clamping mechanism to clamp the curtain body. Then, the gantry moves the curtain body to the rear end of the conveying track to cover the goods on the conveying track, thereby tightly wrapping the bulk goods inside the curtain body, forming a whole, and then conveying them into the container, making the entire conveying process neat and orderly.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Example 1:

[0031] like Figures 1-9 As shown, the present invention is a bulk cargo loading platform, including a conveyor track 1. Baffles 29 are provided on both sides of the conveyor track 1 to prevent cargo from falling off the conveyor track 1 (baffles 29 in the middle of the conveyor track 1 are omitted in the figure). Rollers 30 are installed on the baffles 29 to reduce the friction between the cargo and the baffles 29 during the cargo conveying process. A gantry 2 that can move along the cargo conveying direction is provided on the conveyor track 1. A curtain assembly 3 is installed at the front end of the gantry 2 along its moving direction, and a curtain assembly 9 is provided at the rear end of the gantry 2.

[0032] The conveying track 1 includes two parallel conveying lines, which can be close to or far apart from each other. Each conveying line is equipped with the aforementioned gantry 2, and the two gantry 2 can also be close to or far apart from each other. The accompanying drawings in this invention are all schematic diagrams of a structure with two conveying lines.

[0033] The bottom of the gantry 2 is equipped with a third drive mechanism that drives its reciprocating motion. The third drive mechanism includes a third motor 25, a gear 26 fixed on the output end of the third motor 25, and a rack 27 on the conveying track 1. The gear 26 meshes with the rack 27. There are two sets of the third drive mechanism, located on both sides of the gantry 2 respectively. Rollers are installed at the bottom of the gantry 2, and guide rails are installed on the conveying track 1. When the third motor 25 is started, the third motor 25 drives the gear 26 to rotate on the rack 27, thereby realizing the reciprocating movement of the gantry 2.

[0034] The curtain assembly 3 includes a lifting mechanism 4 and a retractable curtain body 5. The curtain body 5 has a retraction mechanism 28 at its tail for retraction. The retraction mechanism 28 includes a fourth motor, and a roller is connected to the output end of the fourth motor. The curtain body 5 is wound around the roller. The curtain body 5 is located inside the lifting mechanism 4. The bottom of the lifting mechanism 4 is provided with a first clamping mechanism 6 for clamping the curtain body 5. The front end of the conveying track 1 is provided with a second clamping mechanism 12 for clamping the curtain body 5.

[0035] The curtain assembly 9 includes a telescopic mechanism 10 and a curtain body 11 mounted on the telescopic mechanism 10. The telescopic mechanism 10 can drive the curtain body 11 to rise and fall. The curtain body 11 is located inside the telescopic mechanism 10. The two ends of the gantry 2 perpendicular to the cargo conveying direction are provided with protective covers. The protective covers, the curtain assembly 3, and the curtain assembly 9 can form a cavity to accommodate cargo. When the lifting mechanism 4 drives the curtain body 5 to move downward to the bottom, the telescopic mechanism 10 drives the curtain body 11 to move downward to the bottom. The cavity formed by the curtain body 5, the curtain body 11, and the protective cover is relatively closed, so the cargo can be wrapped inside. Moreover, both the lifting mechanism 4 and the telescopic mechanism 10 have a certain rigidity, so they can support the curtain body 5 and the curtain body 11 on the inside, preventing the cargo from pushing the curtain body 5 or the curtain body 11 and falling to the outside.

[0036] The lifting mechanism 4 and the telescopic mechanism 10 both include an upper support 16, a lower support 17, and a scissor bracing mechanism 18 located between them. The scissor bracing mechanism 18 includes several pairs of arms distributed vertically. Adjacent pairs of arms in the middle are hinged and form two hinge points. One of the two hinge points is fixed to the crossbar 31, and the other hinge point is slidably connected to the groove on the crossbar 31. A first motor 19 is installed above the upper support 16. The output end of the first motor 19 is connected to a first lead screw 20, which is threaded. The first nut seat 21 is connected to the scissor bracing mechanism 18. One of the two arms at the top of the scissor bracing mechanism 18 is hinged to the upper bracket 16, and the other arm is hinged to the first nut seat 21. The lower bracket 17 is also provided with a sliding groove. One of the two arms at the bottom of the scissor bracing mechanism 18 is hinged to the lower bracket 17, and the other arm is slidably connected in the sliding groove of the lower bracket 17. When the first motor 19 is started, the first lead screw 20 rotates and drives the first nut seat 21 to move, thereby driving the scissor bracing mechanism 18 to open and close, realizing the lifting of the curtain assembly 3 or the extension of the telescopic mechanism 10.

[0037] Each crossbar 31 in the telescopic mechanism 10 is fixed with a stop bar 32 for limiting the curtain body 11. When the lifting mechanism 4 drives the curtain body 5 to move upward, the retraction mechanism 28 at the tail of the curtain body 5 synchronously retracts the curtain body 5, which can prevent the curtain body 5 from stacking. When the telescopic mechanism 10 drives the curtain body 11 to rise, the stop bar 32 can prevent the curtain body 11 from getting stuck in the telescopic scissor brace mechanism 18 when stacked.

[0038] The first clamping mechanism 6 includes a pushing cylinder 7 and a pushing groove 8. The pushing groove 8 is located on the lower support 17. The output end of the pushing cylinder 7 extends into the pushing groove 8 to press the curtain body 5 between its output end and the groove wall of the pushing groove 8. In the initial state, the output end of the pushing cylinder 7 extends out to press the curtain body 5 onto the groove wall, thereby clamping the curtain body 5. When the gantry 2 moves to the front end of the conveying track 1, the lifting mechanism 4 drives the curtain body 5 to move downward to the second clamping mechanism 12. Then, the output end of the pushing cylinder 7 retracts, and the second clamping mechanism 12 is activated to clamp the curtain body 5.

[0039] The second clamping mechanism 12 includes a clamping cylinder 13 and a clamping rod 14. The clamping rod 14 is bent into a U-shaped structure, and a pressure block 15 is slidably connected to the clamping rod 14. The pressure block 15 and the clamping rod 14 enclose a clamping cavity for clamping the curtain body 5. The clamping cylinder 13 is used to drive the pressure block 15 to slide on the clamping rod 14 to control the size of the clamping cavity, thereby realizing the clamping and releasing of the curtain body 5.

[0040] The curtain assembly 3 and the door curtain assembly 9 can move closer to or further apart from each other. The distance between the curtain assembly 3 and the door curtain assembly 9 can be controlled according to the volume of the goods. A second drive mechanism for driving the door curtain assembly 9 to move along the direction of goods transportation is installed on its top. The second drive mechanism includes a second motor 23. The output end of the second motor 23 is driven by a second lead screw 22. A second nut seat 24 is threaded onto the second lead screw 22 and is fixed to the top of the door curtain assembly 9. Figure 9 The diagram shown is of two gantry frames 2. Therefore, a transmission mechanism is provided between the second motor 23 and the two second lead screws 22. The transmission mechanism includes a transmission shaft with two first bevel gears mounted on it. Each of the two second lead screws 22 has a second bevel gear mounted on its end. The two first bevel gears mesh with the two second bevel gears respectively. The gantry frame 2 is provided with a slide rail, and the top of the curtain assembly 9 is provided with a slider that cooperates with the slide rail.

[0041] Working principle:

[0042] First, the lifting mechanism 4 moves the curtain body 5 downward, and the telescopic mechanism 10 moves the curtain body 11 upward. The forklift transports the bulk goods into the cavity of the mast 2. After the transport is completed, the telescopic mechanism 10 moves the curtain body 11 downward. The curtain assembly 3 and the curtain assembly 9 surround the goods between them. The distance between the curtain assembly 3 and the curtain assembly 9 can be adjusted according to the volume of the goods. Then, the mast 2 and the goods move forward synchronously. After reaching the designated position, the lifting mechanism 4 moves the curtain body 5 upward, and the telescopic mechanism 10 moves the curtain body 11 upward. The mast 2 moves backward over the goods to transport the next batch of goods. When the goods are transported, the mast 2 moves to the front end of the conveying track 1. The lifting mechanism 4 moves the curtain body 5 downward to the designated position. The first clamping mechanism 6 releases the curtain body 5, and the second clamping mechanism 12 clamps the curtain body 5. Then, the mast 2 moves backward while moving the curtain body 5 to unroll and cover the goods on the conveying track 1. Finally, the covered goods are transported into the container.
