Description

Technical Field

[0001] The present invention relates to the technical field of loader assembly production lines, and specifically relates to a loader assembly production line with a compact layout. Background Art

[0002] A loader is an engineering machinery and equipment used for loading, handling, and transporting materials. It is usually widely used in earthwork projects, mines, construction sites, ports, etc. Loaders usually have a hydraulic transmission system, hydraulic steering, and a tire chassis, and can adapt to different workplaces and operating environments.

[0003] For example, the Chinese patent with the publication number CN210281332U discloses a loader automatic assembly production line, including a general assembly line, a rear frame sub-assembly line, a front frame sub-assembly line, an engine sub-assembly line, and a boom sub-assembly line. The general assembly line includes several workstations arranged in sequence. An empty trolley storage area is arranged at the head end of the general assembly line, and a down-line lifting platform is arranged at the tail end of the general assembly line. The engine sub-assembly line is flush with the ground, and the tail end of the engine sub-assembly line is located at the second workstation of the general assembly line.

[0004] However, the above solution has the following deficiencies: In the above patent, by setting up dedicated rear frame sub-assembly lines, front frame sub-assembly lines, engine sub-assembly lines, and boom sub-assembly lines, the assembly efficiency is improved. However, in actual use, the components used to assemble the loader are sequentially placed on the ground of the production workshop. When the loader needs to be assembled, operators need to use forklifts or overhead cranes to move the components to the assembly area of the production line, resulting in low assembly efficiency. Moreover, the stacking of loader components on the ground of the production workshop will also reduce the overall usable area of the workshop. Therefore, we introduce a loader assembly production line with a compact layout. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0023] Example 1:

[0024] A compact loader assembly production line includes a mounting base plate 19. Two groups of sliding plates 1 are fixedly connected to the upper end of the mounting base plate 19. A connecting seat 6 is movably connected between the two groups of sliding plates 1. Both ends of the connecting seat 6 are fixedly connected to a traction mechanism. The traction mechanism is arranged inside the sliding plate 1. The connecting seat 6 is driven to move by the traction mechanism. A U-shaped support plate 24 is movably connected to the upper side of the connecting seat 6. A U-shaped positioning plate 5 is movably connected to the upper end of the U-shaped support plate 24. The loader frame can be positioned and supported by the U-shaped positioning plate 5. Both ends of the U-shaped support plate 24 are fixedly connected to a first hydraulic cylinder 4. The output end of the first hydraulic cylinder 4 is fixedly connected to the U-shaped positioning plate 5. When it is necessary to adjust the distance between the frames above the two U-shaped positioning plates 5, the first hydraulic cylinder 4 is opened to drive the U-shaped positioning plate 5 connected to its output end to move, thereby controlling the distance between the two U-shaped positioning plates 5;

[0025] A number of groups of support columns 12 are provided on both sides of the mounting base plate 19. The upper ends of the number of groups of support columns 12 are fixedly connected to a cross beam 14. A traveling crane 13 is movably connected to the upper ends of the two cross beams 14. By moving the traveling crane 13 above the two cross beams 14, the loader parts can be hoisted to the corresponding positions. One end of the mounting base plate 19 is fixedly connected to a storage table 8. One end of the storage table 8 away from the mounting base plate 19 is fixedly connected to a protective box 10. A rotating column 17 is movably connected inside the upper end of the protective box 10. Storage cavities 16 are opened in the inner circumference of the outer side of the rotating column 17. A number of groups of storage plates 18 are movably connected inside the storage cavities 16. One end of the number of groups of storage plates 18 close to the storage cavity 16 is fixedly connected to a folding plate 21. The folding plate 21 is composed of a number of small metal plates. When a group of storage plates 18 moves to the lower end of the storage cavity 16, as the folding plate 21 continuously moves downward, the folding plate 21 will fold, and then the number of groups of storage plates 18 can be stacked together in sequence;

[0026] The upper end of the folding plate 21 extends out of the rotating column 17 and is fixedly connected to the winding roller 29. The winding roller 29 is fixedly connected to the output end of the second motor 23. The second motor 23 is fixedly installed at the upper end of the rotating column 17. By turning on the second motor 23, the winding roller 29 is driven to rotate. The folding plate 21 is wound or released by the rotation of the winding roller 29. A connecting wheel 30 is fixedly connected to the end of the winding roller 29 away from the second motor 23. A number of groups of limiting holes 28 are formed in the outer side of the connecting wheel 30. A limiting mechanism is clamped in the limiting holes 28. The limiting mechanism is arranged in the rotating column 17. A discharge port 9 is formed in the inner side of the protective box 10 close to the placing table 8. A feeding port 20 is formed in the inner side of the protective box 10 away from the placing table 8. When it is necessary to wind or release the folding plate 21, the clamping of the limiting mechanism to the limiting holes 28 is cancelled at this time. After the winding roller 29 winds or releases the folding plate 21, the limiting mechanism is controlled to be re-clamped into the limiting holes 28.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, in order to enable the loader to move on the production line when installing loader components, the traction mechanism includes two groups of traction ropes 2. The two ends of the connecting seat 6 are respectively fixedly connected to the traction ropes 2. The end of the traction rope 2 away from the connecting seat 6 is fixedly connected to the wire reel 7. The wire reel 7 is movably connected between the two groups of sliding plates 1. A first motor 25 is fixedly installed on one side of the sliding plate 1. The output end of the first motor 25 is fixedly connected to the wire reel 7. When it is necessary to move the loader components during the assembly process of the loader, by turning on the first motor 25, the wire reel 7 is driven to rotate. The traction rope 2 is wound or released by the rotation of the wire reel 7, so that the connecting seat 6 connected to the other end of the traction rope 2 moves back and forth;

[0029] Two groups of guide wheels 27 are fixedly connected to both sides of the connecting seat 6. The guide wheels 27 are movably connected to the guide grooves 3. The guide grooves 3 are opened in the sliding plate 1. The lower end of the U-shaped support plate 24 is fixedly connected to the output end of the second hydraulic cylinder 26. The second hydraulic cylinder 26 is fixedly installed in the connecting seat 6. When assembling the loader, by opening the second hydraulic cylinder 26, the U-shaped support plate 24 moves upward, thereby lifting the loader frame. When the loading is completed, by controlling the second hydraulic cylinder 26, the U-shaped support plate 24 moves downward to its original position. The limiting mechanism includes a T-shaped limiting rod 31. The T-shaped limiting rod 31 is slidably connected in the limiting cavity 32. The limiting cavity 32 is opened in the rotating column 17. The clamping end of the T-shaped limiting rod 31 is clamped in the limiting hole 28. A connecting spring 34 is fixedly connected in the limiting cavity 32. The other end of the connecting spring 34 is fixedly connected to the T-shaped limiting rod 31. An electromagnet 33 is arranged inside the connecting spring 34. One end of the electromagnet 33 is fixedly connected to the limiting cavity 32. By turning on the electromagnet 33, the T-shaped limiting rod 31 is disengaged from the limiting hole 28. By turning on the second motor 23, the winding roller 29 winds the folding plate 21. After the winding is completed, turn off the electromagnet 33 so that the T-shaped limiting rod 31 is re-clamped into the limiting hole 28 under the elastic force of the connecting spring 34;

[0030] A bracket 11 is arranged on the upper side of the protective box 10. The bracket 11 is fixedly connected to the protective box 10. A connecting motor 15 is fixedly installed in the bracket 11. The output end of the connecting motor 15 is fixedly connected to the rotating column 17. A number of sets of transmission rollers 22 are movably connected inside the upper ends of a number of sets of storage plates 18 and the storage table 8. Through the transmission motors connected to one ends of the number of sets of transmission rollers 22, the transmission rollers 22 can be driven to rotate. Through the rotation of the number of sets of transmission rollers 22, the storage plates 18 are moved above the storage table 8.

[0031] Working principle: When in use, turn on the second motor 23 to drive the winding roller 29 to rotate, so that a number of sets of storage plates 18 are stacked under the storage cavity 16. At this time, through an external forklift, the parts are put into the storage cavity 16 through the feeding port 20 and placed above the uppermost storage plate 18. After the placement is completed, turn on the second motor 23 again to drive the winding roller 29 to rotate, so that the folding plate 21 is wound. After the folding plate 21 is wound, it drives the storage plate 18 to move upward. When another set moves to the position of the feeding port 20, at this time, turn off the electromagnet 33 so that the T-shaped limiting rod 31 is clamped into the limiting hole 28 under the elastic force of the connecting spring 34, making the winding roller 29 unable to continue rotating. After placing another set of parts above the new storage plate 18, turn on the electromagnet 33 again so that the T-shaped limiting rod 31 is disengaged from the limiting hole 28. At this time, turn on the second motor 23 again to wind the folding plate 21 by the winding roller 29;

[0032] After all the parts are placed above several groups of storage plates 18, at this time, by turning on the connecting motor 15 to drive the rotating column 17 to rotate, another storage cavity 16 is moved to the position of the feeding port 20. At this time, another kind of parts can be placed above the new storage plate 18 in sequence according to the above method. The large front and rear vehicle frames can be placed above the two U-shaped positioning plates 5 by the traveling crane 13. By turning on the first hydraulic cylinder 4 to adjust the distance between the two U-shaped positioning plates 5, the installation of the front and rear vehicle frames can be made more convenient. When other parts need to be installed, such as the engine, tires, etc., move the traveling crane 13 above the storage table 8. By turning on the connecting motor 15 to drive the rotating column 17 to rotate, the corresponding storage cavity 16 is moved to the position of the discharging port 9. By turning on several groups of driving rollers 22, the parts are moved from the discharging port 9 to above the storage table 8. The parts above the storage table 8 are lifted by the traveling crane 13 to the loading vehicle frame for installation. After the installation is completed, by turning on the traction mechanism to drive the U-shaped support plate 24 with the loader placed on it to move to the leftmost side, and by controlling the second hydraulic cylinder 26 to make the U-shaped support plate 24 move downward. After the loader wheels contact the ground, the loaded loader can be driven away from the production line.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
