Description

Technical Field

[0001] The invention belongs to the technical field of lifting frames, and in particular relates to a load-lifting robot. Background Art

[0002] The load-lifting robot is an intelligent device that highly integrates mechanical, electronic, control and sensing technologies. It can carry and lift heavy objects safely and efficiently. It is widely used in warehouse management, production line automation, logistics and transportation, etc., effectively improving work efficiency, reducing labor costs, and ensuring the safety and accuracy of operations.

[0003] After working for a long time, the load-lifting robot needs to frequently generate friction between its lifting arm and the clamping part, which causes the height of the object to be continuously raised or lowered. However, due to the influence of the working environment and the increase of time, impurities or dust will continue to accumulate between the lifting arm and the clamping part, which will gradually reduce the flexibility of the lifting arm and even cause jamming. When jamming occurs, the displacement process of the object will be dangerous. In order to solve this kind of problem, workers will regularly lubricate and clean the lifting arm and the clamping part. However, the efficiency of manual operation is relatively low and the workload is increased. To this end, we propose a load-lifting robot. Summary of the invention

When the power mechanism is started, the lifting arm 8 will gradually approach the object to be grabbed under its action. During the vertical downward movement of the lifting arm 8, it will continuously contact the slide rail mechanism. A relative displacement occurs between the cleaning component and the lifting arm 8, and the cleaning component continuously scrapes the inner wall of the lifting arm 8 to achieve the purpose of cleaning dust and impurities, increasing smoothness. Subsequently, the brush cleaning belt 26 provided will also be started synchronously to repeatedly wipe and lubricate the inner wall of the lifting arm 8, improving the smoothness and service life of the lifting arm 8 during operation, facilitating the operation. The whole process is synchronized with the operation of the lifting arm 8, and there is no need for manual wiping and cleaning of the lifting arm 8, reducing the operation burden.

[0031] For example 2, please refer to Figures 1 to 11 On the basis of the first embodiment, the positions of the two slide rail mechanisms are far away from each other and symmetrical, the power mechanism includes a motor 4, a connecting belt 1 5 and three driving members 7, the two motors 4 are fixedly connected to one side of the base member 1, one side of the base member 1 is fixedly connected to two symmetrical and spaced-apart protective shells 2, each driving member 7 includes a shaft and a large gear, one end of the shaft is fixedly connected to one end of the large gear, one end of each shaft passes through the protective shell 1 2, the large gear is located between the protective shell 1 2 and the base member 1, one side of the protective shell 2 is fixedly connected to a protective shell 2 3, the protective shell 2 3 does not contact the boom 8, the connecting belt 1 5 is transmission-connected between the outer wall of the output shaft of the motor 4 and the outer wall of the shaft located in the middle, the outer wall of the shaft located in the middle and the outer walls of the other two shafts are transmission-connected with a connecting belt 2 6, the two connecting belts 2 6 and the connecting belt 1 5 are not in contact with each other, the connecting belt 1 5 and the two connecting belts 2 6 are located at the protective shell 2 3 Between the shell 1 and the guard 2, tooth grooves 10 are provided on the outer walls of both sides of the lifting arm 8, and the large gear is in meshing relationship with the tooth grooves 10. The clamping member 9 is fixedly connected to the outer wall of one side of the guard 2. The outer walls of both sides of the clamping member 9 are fixedly connected with two sets of symmetrical rolling members, and the rolling members include a number of supporting blocks 12 with equal spacing. The cross section of each supporting block 12 is an isosceles trapezoid. Rollers 13 are provided on the outer walls of both sides of the supporting block 12. The two rollers 13 are fixedly connected. A short rod is connected, the short rod passes through the interior of the supporting block 12 and is in a rotational connection with the supporting block 12. Through grooves are provided at both ends of the lifting arm 8. The cross-section of the lifting arm 8 is in the shape of a weight through the through grooves. Composite grooves 11 are provided at both ends of the inner walls of the two through grooves. A ball 14 is rollingly connected to the top of each supporting block 12. The roller 13 and the ball 14 are in a rolling connection with the inner wall of the composite groove 11, and the supporting block 12 is in a sliding connection with the inner wall of the composite groove 11. Through the power mechanism set up, when the two motors 4 are started together, under the connection action of the connecting belt 1 5 and the two connecting belts 2 6, the three driving parts 7 will be started synchronously, and the large gears work together to mesh the lifting arm 8 to push it and make it displace in the vertical direction. The setting of the protective shell 1 2 protects the connecting belt 1 5 and the two connecting belts 2 6. In the process of displacement of the lifting arm 8, since a number of rollers 13 and balls 14 are in a rolling connection relationship with the inner wall of the composite groove 11 opened inside the clamping member 9, the friction between the clamping member 9 and the lifting arm 8 when relative action occurs is indirectly reduced through the setting of the supporting block 12, rollers 13 and balls 14, thereby improving the smoothness of the lifting arm 8 when it is displaced along the two clamping members 9, thereby helping to improve the efficiency of the operation. The weight-type supporting block 12 increases the contact area between the clamping member 9 and the lifting arm 8, thereby improving the connection stability.

[0032] For example 3, please refer to Figures 1 to 11, on the basis of the second embodiment, one end of the clamping member 9 is provided with a first installation groove 15, a second installation groove 25, and two symmetrically arranged and mutually separated rectangular short grooves. A third connecting belt 21 is arranged inside the rectangular short grooves. A first rotating shaft 20 and a second rotating shaft are rotatably connected between the inner walls of the two rectangular short grooves. The first rotating shaft 20 and the second rotating shaft respectively pass through the inside of the first installation groove 15 and the second installation groove 25. The shovel block 16 is fixedly connected inside the first installation groove 15. The first rotating shaft 20 passes through the inside of the shovel block 16. The cross-section of the shovel block 16 is in the shape of a right trapezoid. A collecting block 17 is slidably connected inside the shovel block 16. Rubber strips 18 are fixedly connected to the outer walls on both sides of the collecting block 17. Both rubber strips 18 are in a clamping connection with the inner wall of the shovel block 16. A through-type finger-shaped groove 19 is opened at one end of the collecting block 17. The outer wall of the first rotating shaft 20 is slidably connected to the inner wall of the finger-shaped groove 19. The third connecting belt 21 is in a transmission connection with both first rotating shafts 20. A small gear 22 is fixedly connected to one end of the first rotating shaft 20. A rectangular long groove 23 is opened inside the boom 8. A plurality of equally spaced tooth blocks 24 are fixedly connected to one end of the inner wall of the rectangular long groove 23. The small gear 22 is in a meshing relationship with each tooth block 24. A square block 31 is fixedly connected to the side wall of the collecting block 17. A connecting rod 32 is fixedly connected to one end of the square block 31. A sliding groove 33 is opened inside the first installation groove 15. The square block 31 is in a clamping connection with the shovel block 16. The square block 31 is slidably connected to the inner wall of the sliding groove 33. A connecting component is fixedly connected to the top of the connecting rod 32. The connecting component includes a vertical rod 34 and a horizontal rod 35. Both the vertical rod 34 and the horizontal rod 35 are located inside the through groove. The bottom end of the vertical rod 34 is fixedly connected to the top of the connecting rod 32. The top end of the vertical rod 34 is fixedly connected to the bottom surface of the horizontal rod 35. A bottom block 36 is fixedly connected to one end of the horizontal rod 35. The bottom block 36 is clamped between the inner walls on both sides of the U-shaped block 40. Side grooves 41 are opened on both inner walls of the U-shaped block 40. The cross-section of the side groove 41 is in the shape of a sector. Rubber strips 42 are fixedly connected to both the top end and the bottom end of the inner wall of the side groove 41. A through-type side groove 38 is opened on one side of the bottom block 36. A stop member 39 is slidably connected inside the side groove 38. A vertical rod is fixedly connected to the top end of the stop member 39. The top end of the vertical rod passes through the top of the bottom block 36 and is fixedly connected to a top plate 37. The outer wall of the stop member 39 can be simultaneously clamped inside the two side grooves 41. The height of the bottom block 36 is greater than that of the U-shaped block 40. In the initial state: As shown in the attached Figure 1 of the specification, the distance between the top member 44 at the bottom end of the boom 8 and the ground, that is, the distance from the object to be grabbed, is relatively high. As shown in the attached Figure 5 of the specification and 6It can be seen that the shovel block 16 is arranged on the side of the clamping member 9 away from the object to be grasped. From this, it can be obtained that when the boom 8 moves downward, the inner walls of the boom 8, that is, the inner walls of the two through grooves, will pass over the shovel block 16. By providing the shovel block 16, since it is in a sliding connection relationship with the inner wall of the boom 8, during the vertical downward movement of the boom 8, the shovel block 16 will scrape it, thereby cleaning the dust and impurities on the inner wall of the boom 8, that is, the inner wall of the through groove. Through the collection block 17 clamped inside the shovel block 16, these scraped dust and impurities will be collected inside the collection block 17. When the operation is completed, the operator can take out the collection block 17 by first moving the connecting rod 32 upward and then displacing it to the left or right, and then process the collected dust or impurities. As for the detailed steps of taking out, the top plate 37 needs to be adjusted first. By default, the top plate 37 and the bottom block 36 are parallel to each other in the top view state. At this time, the overall formed by the top plate 37 and the bottom block 36 can be regarded as an integral rectangular block, as shown in the attached Fig.10 In the general state, at this time, under the connection of the vertical rod, the stopper 39 is clamped between the second rubber strips 42. By providing the second rubber strips 42, the friction generated when the stopper 39 rotates is increased, so that the stopper 39 will not automatically separate from between the second rubber strips 42 due to the vibration generated during the operation of the robot, improving the stability. Rotate the top plate 37 to make it perpendicular to the bottom block 36, then the stopper 39 will脱离 the inside of the two second side grooves 41 and completely come to the inside of the first side groove 38. Since the two ends of the top plate 37 are already exposed, the two ends of the top plate 37 can be pulled simultaneously to make the bottom block 36脱离 the inner wall between the U-shaped blocks 40. Under the connection of the cross bar 35 and the vertical bar 34, the collection block 17 also moves vertically synchronously, but at this time it is still inside the through groove. Then, drive the top plate 37 in the two side directions of the boom 8, and the collection block 17 can be completely pulled out. The setting of the first rubber strip 18 is also to increase the friction between the shovel block 16 and the collection block 17, improve the stability of the collection block 17, and facilitate the collection operation.

[0033] Embodiment 4, please refer to Figures 1 to 11On the basis of the third embodiment, the outer wall of the second rotating shaft is connected to the brush cleaning belt 26, the inner walls on both sides of the installation groove 25 are connected to the third rotating shaft, the outer wall of the third rotating shaft is fixedly connected to the inner wall of the brush cleaning belt 26, and a fine-porous sponge 27 is arranged at one end of the inner wall of the installation groove 25. The interior of the fine-porous sponge 27 absorbs lubricating oil, and the interior of the fine-porous sponge 27 is fixedly connected to a delivery pipe 28. One end of the delivery pipe 28 passes through the interior of the protective shell 1 2 and is fixedly connected to an oil filling port 43. The collection mechanism A temporary storage box 45 is included. A through transverse groove is provided on the top of a top member 44. The temporary storage box 45 is clamped inside the transverse groove. The height, width and length of the temporary storage box 45 are equal to the transverse groove. The outer walls on both sides of the temporary storage box 45 are fixedly connected with bending blocks 30. The cross section of the bending block 30 is L-shaped. The outer walls on both sides of the top member 44 are rotatably connected with clamping blocks 29. The clamping blocks 29 can be clamped between the bending block 30 and the temporary storage box 45. An opening is provided at the top of the temporary storage box 45. The length of the opening is greater than the distance between the two through grooves. By setting the small gear 22 and the tooth block 24, as the lifting arm 8 is displaced, the small gear 22 is stationary relative to the tooth block 24, and the plurality of tooth blocks 24 are displaced with the lifting arm 8 and continuously act on the small gear 22 meshing therewith, so that the small gear 22 rotates. Under the connection of the connecting belt 3 21, the first rotating shaft 20, the second rotating shaft and the third rotating shaft, the brush cleaning belt 26 continuously rotates and wipes the inner wall of the through groove at the same time, and at the same time presses one side of the fine-porous sponge 27. The lubricating oil inside the fine-porous sponge 27 will be contaminated onto the brush cleaning belt 26 through the above-mentioned contact process, and then wipe the inner wall of the through groove to achieve the purpose of lubrication, reduce friction, and greatly improve smoothness. Because the distance between the brush cleaning belt 26 and the object to be grasped is closer than that of the shovel block 16, As the lifting arm 8 moves downward, the cleaning operation is performed first and then the lubrication operation. The lubricating oil can be continuously added to the fine-pored sponge 27 through the provided delivery pipe 28 and the oil filling port 43. The finger-shaped groove 19 is provided so that the rotation of the first rotating shaft 20 will not affect the collecting block 17. As the lubrication operation is performed for a long time, the lubricating oil may continuously move downward and drip. Through the provision of the temporary storage box 45, since the top of the temporary storage box 45 is provided with an opening, and the length of the opening is greater than the spacing between the two through grooves, that is, the lubricating oil sliding down from the inner wall of the through groove will eventually be concentrated into the interior of the temporary storage box 45. The two card blocks 29 are simultaneously rotated and detached from the interior of the two bending blocks 30, and the temporary storage box 45 can be pushed out from the inside of the top component 44, which is convenient for subsequent processing.

[0034] In actual use, through the power mechanism set up, when the two motors 4 are started together, under the connection action of the connecting belt 1 5 and the two connecting belts 2 6, the three driving members 7 will be started synchronously, and the large gears work together to mesh with the lifting arm 8 to push it and make it displace in the vertical direction. In this process, the shovel block 16 will scrape it, and then clean the dust and impurities on its inner wall, that is, the inner wall of the through groove. The scraped dust and impurities will be collected in the collecting block 17 through the collecting block 17 that is clamped inside the shovel block 16. When the operation is completed, the operator can take out the collecting block 17 by first moving the connecting rod 32 upward and then moving it to the left or right. , and then process the collected dust or impurities. With the displacement of the lifting arm 8, the pinion 22 is stationary relative to the tooth block 24. Several tooth blocks 24 move with the lifting arm 8 and continuously act on the pinion 22 meshing therewith, so that the pinion 22 rotates. Under the connection of the connecting belt three 21, the first rotating shaft 20, the second rotating shaft and the third rotating shaft, the brush cleaning belt 26 rotates continuously and wipes the inner wall of the through groove at the same time, and presses one side of the fine-porous sponge 27 at the same time. The lubricating oil inside the fine-porous sponge 27 will be contaminated by the brush cleaning belt 26 through the above-mentioned contact process, and then wipe the inner wall of the through groove to achieve the purpose of lubrication, reduce friction, and greatly improve smoothness.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
