Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board transportation, and particularly to a forklift device for continuous transportation. Background Art

[0002] During the production process of gypsum boards, since gypsum boards occupy a large area, the produced gypsum boards often need to be neatly stacked to save the area of the factory area and also be more convenient for subsequent packaging and transportation. Usually, multiple gypsum boards are packaged together to form a gypsum board stack. After each stack is packaged, a forklift is used to unload one stack, and after unloading, the forklift is used to transport the stacks to the transfer area in sequence, and then a large forklift is used to transplant and store each individual gypsum board stack.

[0003] After the gypsum board stacks are completed, they are usually transplanted and stored by a forklift. However, the transportation method of the forklift going back and forth has low efficiency, and a large number of gypsum board stacks are likely to accumulate at the starting end of the gypsum board stack transportation. There is also a transportation method in the prior art that uses a gypsum board transportation line. Due to the large volume and weight of the gypsum board stacks, the flatness of the gypsum board stacks needs to meet certain conditions. Due to the inertial effect during transportation, some gypsum boards in the gypsum board stack are likely to shift on the roller conveyor line, and the stability of the gypsum board stack during transportation cannot be ensured.

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] As Figure 1 shown, the present invention provides a forklift device for continuous transportation, which includes a retractable forklift structure 1, a transportation drive structure 2, a transportation limit guide rail 3, and a self-locking limit structure 4.

[0054] Among them, a plurality of retractable forklift structures 1 are provided. The retractable forklift structure 1 is used to fork up the gypsum board stack 5 for feeding and drive the gypsum board stack 5 to transport forward. The retractable forklift structure 1 can be telescoped to perform a forking action on the gypsum board stack 5 in the extended state, and drive the gypsum board stack 5 to move to the transportation line in the retracted state.

[0055] The transportation drive structure 2 is arranged between the output end of the gypsum board stack 5 and the gypsum board stack storage. The retractable forklift structures 1 are equally spaced and installed on the transportation drive structure 2. The transportation drive structure 2 is used to drive the retractable forklift structure 1 to transport forward along the transportation line to unload the gypsum board stack 5, and drive the retractable forklift structure 1 that has completed unloading to reset to the initial position for loading.

[0056] The transportation limit guide rail 3 is arranged on the side of the transportation drive structure 2. The transportation limit guide rail 3 is used to limit the transportation trajectory of the transportation drive structure 2.

[0057] The self-locking limit structure 4 is arranged on the retractable forklift structure 1. A fixed connection point and a selectable connection point are formed on the self-locking limit structure 4. Both the retractable forklift structure 1 and the transportation drive structure 2 are connected to the fixed connection point. The self-locking limit structure 4 is used to adjust the connection relationship between the transportation drive structure 2 and the selectable connection point based on the position of the retractable forklift structure 1 on the transportation limit guide rail 3, so as to adjust the connection state between the retractable forklift structure 1 and the transportation drive structure 2.

[0058] Among them, in the double-point connection state of the retractable forklift structure 1 and the transportation drive structure 2, the self-locking limit structure 4 can adjust the angle of the retractable forklift structure 1 to adjust the angle during the transportation of the gypsum board stack 5.

[0059] In the embodiments of the present invention, by combining the retractable forklift structure 1 and the transportation drive structure 2, the transportation drive structure 2 drives a plurality of retractable forklift structures 1 to transport forward along the transportation line, realizing the transportation and blanking of the gypsum board stack 5, improving the transportation efficiency of the retractable forklift structure 1, and limiting the transportation trajectory of the transportation drive structure 2 through the transportation limit guide rail 3, establishing a double-point connection state with the transportation drive structure 2 during the linear transportation of the retractable forklift structure 1 to ensure the stability of the gypsum board stack 5 during transportation. In addition, the self-locking limit structure 4 can adjust the angle of the retractable forklift structure 1 to adjust the angle of the gypsum board stack 5 during transportation, so that the gypsum board stack 5 is limited within the retractable forklift structure 1 during transportation, further improving the stability of the gypsum board stack 5 during transportation.

[0060] In the present invention, the transportation drive structure 2 drives the retractable forklift structure 1 to transport forward along the transportation line to blank the gypsum board stack 5, and drives the retractable forklift structure 1 that has completed blanking to reset to the initial position for loading. The transportation drive structure 2 of the present invention adopts the following preferred embodiments, as Figure 2 shown, the transportation drive structure 2 includes a transportation toothed chain 21, a transmission sprocket 22 arranged inside the transportation toothed chain 21, and a first drive motor 23 arranged on the transmission sprocket 22; the transportation toothed chain 21 meshes with the transmission sprocket 22, the transmission sprocket 22 is arranged at the output end of the first drive motor 23, and the transmission sprocket 22 is arranged as at least two.

[0061] In the above embodiment, the first drive motor 23 drives the transmission sprocket 22 to rotate, thereby driving the transportation toothed chain 21 to transport forward.

[0062] The main structure of the transportation toothed chain 21 of the present invention is as follows, as Figure 2 and Figure 5 shown, the transportation toothed chain 21 is composed of a toothed chain plate group 211, a connecting plate 212, and an external meshing tooth plate 213; the toothed chain plate group 211, the connecting plate 212, and the external meshing tooth plate 213 are all arranged as multiple, adjacent toothed chain plate groups 211 are connected by the connecting plate 212, and a connecting guide shaft 214 is arranged at the connection, and the external meshing tooth plate 213 is arranged at the outer end of the connecting guide shaft 214, and the transmission sprocket 22 meshes with the external meshing tooth plate 213.

[0063] In the above embodiments, the driving sprocket 22 rotates to drive the external meshing tooth plate 213 to move forward, thereby driving the overall forward transportation of the conveying toothed chain 21. Among them, the toothed chain plate group 211, the connecting plate 212, and the external meshing tooth plate 213 are all movably arranged on the connecting guide shaft 214. Therefore, the relative states among the toothed chain plate group 211, the connecting plate 212, and the external meshing tooth plate 213 can be in relative motion. In the state where the conveying toothed chain 21 is in linear transportation, the toothed chain plate group 211 and the connecting plate 212 can be limited by the self-locking limiting structure 4, so that the toothed chain plate group 211 and the connecting plate 212 are in a relatively static state, ensuring the stable transportation of the conveying toothed chain 21 in the linear transportation state.

[0064] In order to ensure the stability of the conveying toothed chain 21, the present invention limits the transportation trajectory of the transportation driving structure 2 through the transportation limiting guide rail 3. The transportation limiting guide rail 3 of the present invention adopts the following preferred embodiments, such as Figure 3 and Figure 4 As shown, the transportation limiting guide rail 3 includes a straight limiting frame 31 and an arc limiting frame 32; both the straight limiting frame 31 and the arc limiting frame 32 are arranged on both sides of the conveying toothed chain 21 and are connected to each other. A straight limiting channel 33 is provided on the inner side wall of the straight limiting frame 31, and an arc limiting channel 34 is provided on the inner side wall of the arc limiting frame 32. The straight limiting channel 33 and the arc limiting channel 34 are connected. The connecting guide shaft 214 is slidably arranged in the straight limiting channel 33 and the arc limiting channel 34, and the widths of the straight limiting channel 33 and the arc limiting channel 34 are the same as the diameter of the connecting guide shaft 214.

[0065] During the forward transportation of the conveying toothed chain 21, the connecting guide shaft 214 slides in the straight limiting channel 33 and the arc limiting channel 34. In order to reduce the friction between the connecting guide shaft 214 and the inner parts of the straight limiting channel 33 and the arc limiting channel 34, a cloth material can be arranged in the straight limiting channel 33 and the arc limiting channel 34, so that the connecting guide shaft 214 is less obstructed during the sliding process in the straight limiting channel 33 and the arc limiting channel 34.

[0066] In addition, the present invention adjusts the connection relationship between the transportation driving structure 2 and the selected connection point based on the position of the retractable forklift structure 1 on the transportation limiting guide rail 3 through the self-locking limiting structure 4, so as to adjust the connection state between the retractable forklift structure 1 and the transportation driving structure 2. The self-locking limiting structure 4 of the present invention adopts the following preferred embodiments, such as Figure 6 、 Figure 7 and Figure 8As shown in the figure, the self-locking limit structure 4 includes a fixed connection seat 41 provided on the connecting plate 212, a fixed bolt 42 provided on the fixed connection seat 41, a driving cavity 43 provided in the fixed connection seat 41, and an adjusting bolt 44 provided in the driving cavity 43; the fixed connection seat 41 is fixedly installed on the connecting plate 212 through the fixed bolt 42, a fixed threaded hole 45 for installing the fixed bolt 42 is provided on the connecting plate 212, and an adjusting threaded hole 46 for installing the adjusting bolt 44 is provided on the tooth chain plate group 211 located on the same connecting guide shaft 214.

[0067] The above structure is the connection design at the fixed connection point. One end of the fixed connection seat 41 is installed on the connecting plate 212 through the fixed bolt 42. That is to say, the fixed connection seat 41 always moves with the connecting plate 212. Since the connecting plate 212 and the tooth chain plate group 211 are in a relative motion state, in order to ensure the stability of the linear transportation process, it is necessary to connect and limit the connecting plate 212 and the tooth chain plate group 211 during the linear transportation of the transportation tooth chain 21 driving the retractable forklift structure 1.

[0068] In order to connect the connecting plate 212 and the tooth chain plate group 211, the present invention makes the following design, as Figure 8 shown in the figure, a threaded seat 47 is provided in the driving cavity 43, the adjusting bolt 44 is threadedly connected to the threaded seat 47, a gear cap 48 is provided on the adjusting bolt 44, a gear driving bolt 49 is provided on the side of the gear cap 48, a second driving motor 410 is provided on the gear driving bolt 49, and the gear driving bolt 49 is connected to the output end of the second driving motor 410; the gear driving bolt 49 meshes with the gear cap 48.

[0069] Initially, the end of the adjusting bolt 44 is far from the adjusting threaded hole 46. The second driving motor 410 drives the gear driving bolt 49 to rotate, drives the gear cap 48 to rotate, and thus drives the adjusting bolt 44 to rotate. The adjusting bolt 44 spirals into the adjusting threaded hole 46 during rotation on the threaded seat 47, so that the adjusting bolt 44 is connected to the adjusting threaded hole 46, thereby realizing the connection between the fixed connection seat 41 and the tooth chain plate group 211. Since the fixed connection seat 41 itself is fixed to the connecting plate 212, at this time, the connecting plate 212, the fixed connection seat 41, and the tooth chain plate group 211 are all connected together and in a relatively static state. In this case, a complete connection between the retractable forklift structure 1 and the transportation driving structure 2 is achieved at the fixed connection point on the transportation tooth chain 21.

[0070] The self-locking limit structure 4 is provided with a fixed connection point and a selectable connection point. When the retractable forklift structure 1 is in a straight-line transportation state, the rotary connection point also needs to be connected to ensure the stability of the fixed connection seat 41. Otherwise, if only one end of the fixed connection seat 41 is installed on the transportation toothed chain 21, the stability is poor. In addition, the selectable connection of the selectable connection point is also to prevent the retractable forklift structure 1 from being blocked and pulled by the transportation drive structure 2 during the arc transportation process.

[0071] In order to establish the connection relationship at the selectable connection point, the present invention makes the following design, as Figure 9 shown, at one end of the fixed connection seat 41 away from the drive cavity 43, a locking cavity 411 is provided. A locking seat 412 is arranged in the locking cavity 411. A threaded locking bolt 413 is arranged on the locking seat 412 in a threaded manner. A prism barrel 414 is arranged at the end of the threaded locking bolt 413. A driving prism 415 is arranged in the prism barrel 414. A locking motor 416 is arranged on the driving prism 415. The driving prism 415 is connected to the output end of the locking motor 416; the driving prism 415 can move in the prism barrel 414. A guiding pointed head 417 is arranged at the end of the threaded locking bolt 413. Locking threaded holes 418 are arranged on both the tooth chain plate group 211 and the connecting plate 212 corresponding to the selectable connection point position on the transportation toothed chain 21. A guiding hole 419 is arranged at the bottom inside the locking threaded hole 418; the threaded locking bolt 413 is correspondingly installed in the locking threaded hole 418 in a threaded manner.

[0072] In the initial state, the guiding pointed head 417 is far away from the locking threaded hole 418. Driving the locking motor 416 drives the driving prism 415 to rotate, thereby driving the prism barrel 414 to rotate. Under the rotation action of the prism barrel 414, the threaded locking bolt 413 rotates on the locking seat 412, and the threaded locking bolt 413 gradually spirally enters the locking threaded hole 418. The guiding pointed head 417 gradually enters the locking threaded hole 418 and reaches the guiding hole 419 inside. The threaded locking bolt 413 is installed in the locking threaded hole 418, so that the other end of the fixed connection seat 41 is also installed on the transportation toothed chain 21.

[0073] When the retractable forklift structure 1 is in a straight-line transportation, a two-point connection state needs to be established. When the retractable forklift structure 1 is about to enter the arc transportation, the two-point connection state needs to be released. At this time, it is necessary to reversely drive the locking motor 416 to drive the threaded locking bolt 413 to disengage from the locking threaded hole 418 and reset. At this time, only one end of the fixed connection seat 41 is connected to the transportation toothed chain 21, and it will not cause pulling during the arc transportation process.

[0074] In the present invention, in the double-point connection state of the retractable forklift structure 1 and the transportation drive structure 2, the self-locking limit structure 4 can adjust the angle of the retractable forklift structure 1 to adjust the angle during the transportation process of the gypsum board stack 5. In order to drive the angle of the retractable forklift structure 1 to be adjusted, the present invention also makes the following design, asFigure 7 and Figure 10 As shown in Figure 10 , a rotary mounting base 420 is rotatably connected to the fixed connection base 41. A fixed shaft column 421 is provided on the rotary mounting base 420 and is rotatably mounted on the fixed connection base 41 through the fixed shaft column 421. An adjusting worm gear 422 is provided on the fixed shaft column 421. An adjusting worm 423 is meshed on the side of the adjusting worm gear 422. An adjusting motor 424 is provided on the adjusting worm 423, and the adjusting worm 423 is connected to the output end of the adjusting motor 424.

[0075] The angle adjustment process during the transportation of the gypsum board stack is as follows: The adjusting motor 424 drives the adjusting worm 423 to rotate. Under the rotation of the adjusting worm 423, the adjusting worm gear 422 is driven to rotate, thereby driving the fixed shaft column 421 to rotate. The rotation of the fixed shaft column 421 can drive the rotary mounting base 420 to rotate, so as to drive the gypsum board stack 5 to rotate through the retractable forklift structure 1.

[0076] In the present invention, the retractable forklift structure 1 can be telescoped to perform a fork-lifting action on the gypsum board stack 5 in the extended state and drive the gypsum board stack 5 to move to the transportation line in the retracted state. The retractable forklift structure 1 of the present invention adopts the following preferred embodiments, as Figure 11 shown. The retractable forklift structure 1 includes a mounting vertical frame 11 provided on the rotary mounting base 420, a retractable frame 12 provided on the mounting vertical frame 11, and a forklift fork 13 provided on the retractable frame 12. A translation side plate 14 is provided on the retractable frame 12. A driving threaded rod 15 is provided in the mounting vertical frame 11. A third driving motor 16 is connected to the driving threaded rod 15, and the translation side plate 14 is threadedly connected to the driving threaded rod 15. The third driving motor 16 is installed in the mounting vertical frame 11.

[0077] The process of the retractable forklift structure 1 forking the gypsum board stack 5 is as follows: The third driving motor 16 drives the driving threaded rod 15 to rotate. Under the rotation of the driving threaded rod 15, the translation side plate 14 moves outward, thereby driving the retractable frame 12 to move outward. Driven by the transportation of the transportation driving structure 2, the forklift fork 13 enters the bottom of the gypsum board stack 5 and forks up the gypsum board stack 5. Then, the transportation driving structure 2 drives the gypsum board stack 5 to be transported forward through the retractable forklift structure 1.

[0078] In summary, the main implementation process of the present invention is as follows:

[0079] The transportation toothed chain 21 drives the retractable forklift structure 1 for linear transportation: The first driving motor 23 drives the driving sprocket 22 to rotate, thereby driving the transportation toothed chain 21 to be transported forward and driving the retractable forklift structure 1 to be transported to the starting end of the transportation of the gypsum board stack 5;

[0080] Establish the double-point connection state of the retractable forklift structure 1 and the transportation drive structure 2: During the process of the retractable forklift structure 1 changing from arc transportation to linear transportation, the second drive motor 410 drives the gear drive bolt 49 to rotate, driving the gear cap 48 to rotate, thereby driving the adjusting bolt 44 to rotate. The adjusting bolt 44 screws into the adjusting threaded hole 46 during rotation on the threaded seat 47, so that the adjusting bolt 44 is connected to the adjusting threaded hole 46, thereby realizing the connection between the fixed connection seat 41 and the tooth chain plate group 211, and a complete connection between the retractable forklift structure 1 and the transportation drive structure 2 is achieved at the fixed connection point on the transportation tooth chain 21;

[0081] After that, the drive locking motor 416 drives the drive prism 415 to rotate, thereby driving the prism barrel 414 to rotate. Under the rotation action of the prism barrel 414, the threaded locking bolt 413 rotates on the locking seat 412, and the threaded locking bolt 413 gradually screws into the locking threaded hole 418. The threaded locking bolt 413 is installed in the locking threaded hole 418, so that the other end of the fixed connection seat 41 is also installed on the transportation tooth chain 21, completing the double-point connection;

[0082] The retractable forklift structure 1 forks up the gypsum board stack 5 for transportation: The third drive motor 16 drives the drive threaded rod 15 to rotate. Under the rotation action of the drive threaded rod 15, the translation side plate 14 moves outward, thereby driving the retractable frame 12 to move outward. Driven by the transportation of the transportation drive structure 2, the forklift forks 13 enter the bottom of the gypsum board stack 5 and fork up the gypsum board stack 5. After that, the transportation drive structure 2 drives the gypsum board stack 5 to move forward through the retractable forklift structure 1.
