[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 making creative efforts belong to the scope of protection of the present invention.

[0043] The present invention provides a pallet robot for storing and transporting tank bodies.

[0044] First embodiment:

[0045] Please refer to Figures 1 to 6 , a pallet robot for storing and transporting tank bodies, including a pallet robot base 1, an adjusting mechanism 3 and a positioning mechanism 4;

[0046] A carrier plate 2 is installed on the top of the base 1 of the tray robot. A locking groove 8 is formed inside the carrier plate 2. The adjusting mechanism 3 includes a first gear disk 31 and a second gear disk 32. A sliding plate 33 is slidably connected inside the locking groove 8. A positioning cylinder 34 is fixedly provided at the center of the top of the sliding plate 33. A lower spring 35 is installed at the inner bottom of the positioning cylinder 34. An elevating cylinder 36 is slidably connected above the positioning cylinder 34. Spring rods 37 are installed on the upper surface of the sliding plate 33 and on both sides of the positioning cylinder 34. A top plate 38 is fixedly provided at the top of the spring rod 37. A rotating sleeve 39 is rotatably connected at the axis of the top plate 38. A key rod 310 is keyed to the axis of the rotating sleeve 39. An upper spring 311 is sleeved on the outer wall of the key rod 310;

[0047] The positioning mechanism 4 includes two first adjusting rods 41 fixedly provided on the outer wall of the first gear disk 31. First positioning plates 42 are fixedly provided at the outer ends of the two first adjusting rods 41. First elastic universal wheels 43 are installed at the bottoms of the two first positioning plates 42. First spring pins 44 arranged at equal intervals are installed on the outer walls of the two first positioning plates 42. Two second adjusting rods 45 are fixedly provided on the outer wall of the second gear disk 32. Second positioning plates 46 are fixedly provided at the outer ends of the two second adjusting rods 45. Second elastic universal wheels 47 are installed at the bottoms of the two second positioning plates 46. Second spring pins 48 arranged at equal intervals are installed on the outer walls of the two second positioning plates 46.

[0048] Please combine Figure 2 and Figure 5 : In the initial state, the first gear disk 31 and the second gear disk 32 are meshed with each other. In order to ensure that the tank body 9 can be positioned smoothly, the positioning mechanism 4 needs to be adjusted;

[0049] During adjustment, the user needs to rotate the first gear disk 31 and the second gear disk 32 respectively with force. Since the teeth between the first gear disk 31 and the second gear disk 32 are small, during the rotation process, affected by the rotational force, the tooth inclined surfaces in the first gear disk 31 and the second gear disk 32 will be stressed in the rotational direction and move up and down respectively. The first gear disk 31 rotates on the elevating cylinder 36. When the first gear disk 31 is rotated, the first gear disk 31 will continuously control the lower spring 35 to move up and down inside the positioning cylinder 34 through the elevating cylinder 36. Under the influence of the rotational force, the second gear disk 32 above will continuously control the upper spring 311 to move up and down inside the key rod 310;

[0050] Please combine Figure 3: The user needs to rotate the first gear disk 31 to rotate and adjust the first adjusting rod 41 to the 45-degree direction, and then needs to rotate the second gear disk 32 to rotate and adjust the second adjusting rod 45 to the 45-degree direction. A cross-shaped 90-degree included angle structure is formed between the first positioning plate 42 and the second positioning plate 46. Then the user can place the tank body 9 between the first positioning plate 42 and the second positioning plate 46.

[0051] The top of the first gear disk 31 meshes with the bottom of the second gear disk 32. The top of the lifting cylinder 36 is rotationally connected to the first gear disk 31 through a "T" ring.

[0052] Both the upper and lower ends of the upper spring 311 are fixedly connected to the lower surface of the rotating sleeve 39 and the upper surface of the second gear disk 32. The upper surface of the lower spring 35 is in contact with the lower surface of the lifting cylinder 36.

[0053] Please refer to Figure 5 : The bottom of the first gear disk 31 is in a limiting rotational connection with the top of the lifting cylinder 36, which can ensure that the first gear disk 31 can be lifted while rotating, so that the first gear disk 31 will not be affected by interference.

[0054] Secondly, both the first positioning plate 42 and the second positioning plate 46 are designed to be inclined, so that tank bodies 9 of different sizes can be positioned and placed. At the same time, during the positioning and lifting process of the first gear disk 31 and the second gear disk 32, the first positioning plate 42 and the second positioning plate 46 also eliminate the lifting interference during lifting on the first elastic universal wheel 43 and the second elastic universal wheel 47. And during the rotation adjustment process of the first positioning plate 42 and the second positioning plate 46, the first elastic universal wheel 43 and the second elastic universal wheel 47 roll on the carrier plate 2, ensuring the smoothness during adjustment.

[0055] In this embodiment: Compared with the traditional design, the first gear disc 31 and the second gear disc 32 with elastic design are engaged. Before adjustment, the user can rotate the first gear disc 31 and the second gear disc 32 forcefully. During the rotation of the first gear disc 31, it will drive the first positioning plate 42 to move, and the second gear disc 32 will drive the second positioning plate 46 to move. In this way, the user can rotate at any angle, and automatic elastic clamping and limiting can be achieved during the rotation. When the user rotates the first positioning plate 42 and the second positioning plate 46 by 45 degrees respectively along the horizontal direction, the positioning and limiting of the tank body 9 can be directly carried out. If the first positioning plate 42 and the second positioning plate 46 rotate and approach each other, a two-side limiting method is formed, and the user can position and limit the long tank body 9 in a lying-down position. Therefore, compared with using fasteners for installation and adjustment, this design can adjust the angle arbitrarily, can automatically engage and limit after adjustment, avoids cumbersome adjustment and debugging by the user, can achieve rapid adjustment. Secondly, different adjustment angles also have two positioning methods. Finally, after the transportation of the tank body 9 is completed, the user can also conveniently fold, store and transport it.

[0056] The second embodiment:

[0057] Please refer to Figure 3 、 Figure 5 and Figure 7 . A locking mechanism 5 is installed below the sliding plate 33 and inside the locking groove 8. The locking mechanism 5 includes clamping rods 51 fixed to the front and rear of the sliding plate 33. A bottom plate 52 is fixed to the relative side of the two clamping rods 51. Two locking plates 53 are slidably connected to the upper surface of the bottom plate 52 through dovetail-shaped sliding strips. A sliding rod 54 is slidably connected inside the sliding plate 33. A trigger rod 55 is fixed to the bottom end of the sliding rod 54. A limiting spring 56 is sleeved on the outer wall of the sliding rod 54. Two return springs 57 are fixed to the relative side of the two locking plates 53.

[0058] The upper surfaces of the two locking plates 53 are of an inclined surface structure that is high in the middle and low on both sides. The cross-section of the trigger rod 55 is of a tapered structure that is wide at the top and narrow at the bottom. The upper and lower ends of the limiting spring 56 are fixedly connected to the bottom surface of the sliding plate 33 and the upper surface of the trigger rod 55;

[0059] There is a gap between the top end of the sliding rod 54 and the lower surface of the first gear disc 31.

[0060] Please combine Figure 3 and Figure 5 : When the tank body 9 is placed, the bottom of the tank body 9 applies force downward to the upper part of the second gear disc 32. The bottom of the tank body 9 first contacts the top disc 38. The downward force continuously controls the top disc 38 to compress and lower the spring rod 37. When lowering, it controls the upper spring 311 to control the second gear disc 32 to lower continuously and engage to control the first gear disc 31 to lower. At this time, the lower spring 35 is compressed;

[0061] Please combine Figure 7 : When the first toothed disc 31 finally descends, it will control the slide bar 54 to descend and drive the limit spring 56 to extend. During the descent of the slide bar 54, the trigger rod 55 is simultaneously driven to descend. When the trigger rod 55 descends, the outer inclined surface causes the two locking plates 53 to extend and move to both sides following the conical inclination of the trigger rod 55. The movement of the locking plate 53 can form a friction force with the inner wall of the locking groove 8, thereby ensuring that the tank body 9 can be automatically locked after being placed.

[0062] See also Figure 7 : By means of the reset spring 57, after the tank body 9 is transported, when the first toothed disc 31 and the second toothed disc 32 lose force, the two locking plates 53 will automatically reset to the initial state.

[0063] It can be understood that the gap between the top of the slide rod 54 and the top of the first toothed disc 31 is greater than the tooth height of the first toothed disc 31. In this way, in the adjusted state, the first toothed disc 31 will not affect the slide rod 54 during the lifting process. Only when the tank body 9 is placed under force, the first toothed disc 31 will drive the slide rod 54 to descend.

[0064] This embodiment: Compared with the traditional design, this case is designed with a linked locking mechanism 5, which utilizes the downward pressure generated during the placement of the tank body 9. The pressure will automatically force the first gear plate 31 and the second gear plate 32 to be completely engaged and locked, and when the first gear plate 31 is in the process of descending and locking, it will link and control the conical trigger rod 55 to descend. The trigger rod 55 can control the two locking plates 53 to move away from each other and form friction force with the inner wall of the locking groove 8, so that the entire slide plate 33 can be automatically locked and stabilized. Therefore, during the placement of the tank body 9, this design can form two locking effects by utilizing the self-weight of the tank body 9. It is stable and does not require additional locking and positioning by the user. The operation is faster and more efficient.

[0065] Third embodiment:

[0066] See also Figure 1 , Figure 8 and 11 , further comprising a tank body 9, a tensioning mechanism 6 and two moving mechanisms 7;

[0067] The tensioning mechanism 6 comprises a clamping ring 61 sleeved on the top of the tank body 9, and the outer wall of the clamping ring 61 is fixed with four steel cables 62 distributed in an annular manner at equal intervals, and the tail ends of the four steel cables 62 are riveted with rivet rings 63, and the tail ends of the four steel cables 62 and below the rivet rings 63 are installed with positioning sleeves 64, and the bottom of the positioning sleeve 64 is penetrated by a fastening bolt 65, and the outer end of the fastening bolt 65 is threadedly connected with a fastening nut 66;

[0068] The moving mechanism 7 includes an installation box 71 mounted on the upper surface of the carrier plate 2. A motor 72 is mounted on the side wall of the installation box 71 through bolts. The output shaft of the motor 72 is keyway-connected to a positive and negative screw rod 73. The outer wall of the positive and negative screw rod 73 is threadedly connected to a first slider 74 and a second slider 75 respectively. A limiting groove 76 is provided on the inner wall of the installation box 71. A first groove plate 711 and a second groove plate 712 are embedded in the outer wall of the installation box 71. The outer walls of the first slider 74 and the second slider 75 are rotatably connected to a first rotating plate 77 and a second rotating plate 78 respectively. A first pull pin 79 and a second pull pin 710 are fixedly provided on the outer walls of the first rotating plate 77 and the second rotating plate 78 respectively.

[0069] Please refer to Figure 1 and Figure 8 : After the work of the first embodiment and the second embodiment is completed, in order to tighten again, the user needs to sleeved the snap ring 61 on the top of the tank body 9;

[0070] Please refer to Figure 9 and Figure 11 : Then, first pass the positioning sleeve 64 through the ring formed at the bottom of the steel cable 62 in sequence, and then the positioning sleeve 64 needs to be placed on the respective first pull pin 79 and second pull pin 710 in sequence. After the placement is completed, a fastening bolt 65 needs to be penetrated through the bottom of the positioning sleeve 64, and then the fastening nut 66 is rotated, so that the four steel cables 62 are sequentially installed with the first pull pin 79 and the second pull pin 710;

[0071] Please refer to Figure 10 and Figure 11 : Start the motor 72 to drive the positive and negative screw rod 73 to rotate. During the rotation, it will control the first slider 74 and the second slider 75 to move away from each other along the horizontal direction of the limiting groove 76. When the first slider 74 and the second slider 75 are moving, they will drive the first rotating plate 77 and the second rotating plate 78 to control the first pull pin 79 and the second pull pin 710, so that the steel cables 62 first move away from each other along the horizontal direction of the first groove plate 711 and the second groove plate 712, so as to pull the steel cables 62 apart, form an extended tension, and further stabilize the tank body 9;

[0072] When the first pull pin 79 and the second pull pin 710 move to the inclined positions of the first groove plate 711 and the second groove plate 712 respectively, the first pull pin 79 and the second pull pin 710 will flip and descend along the inclined surface. During the descending process, it will control the steel cables 62 to form a descending tension, and the tension will be conducted to the snap ring 61 at the top, thereby extending and pulling down the tank body 9 at four points.

[0073] The first pull pin 79 and the second pull pin 710 are respectively slidably connected to the first groove plate 711 and the second groove plate 712. The first slider 74 and the second slider 75 are slidably connected to the limiting groove 76. Both ends of the positive and negative screw rod 73 are rotatably connected to the installation box 71 through bearings.

[0074] In this embodiment: On the basis of the traditional fastening of the steel cable 62, four steel cables 62 are used to position the placed tank body 9 from four points, and the four steel cables 62 are in a linkage extension to form a tensile tension first. Finally, when the first pull pin 79 and the second pull pin 710 are relatively far away to the inclined plane positions of the first groove plate 711 and the second groove plate 712, the first pull pin 79 and the second pull pin 710 will each move downward. During the downward movement, they will control their respective steel cables 62 to form a downward pulling force. In this way, while the steel cable 62 is extended and tightened, it also forms a downward pulling force, which can further realize the tight positioning of the tank body 9 and ensure the further stability of the tank body 9.

[0075] Please refer to Figures 1 to 11 , the working principle of a tray robot for storing and transporting tank bodies provided by the present invention is as follows:

[0076] Step S1: Rotate the first gear disk 31 and the second gear disk 32 with force respectively. Since the teeth between the first gear disk 31 and the second gear disk 32 are small, during the rotation process, under the influence of the rotational force, the tooth inclined planes in the first gear disk 31 and the second gear disk 32 will be stressed in the rotational direction and move up and down respectively. The first gear disk 31 rotates on the lifting cylinder 36. When the first gear disk 31 is rotated, the first gear disk 31 will continuously control the lower spring 35 to move up and down inside the positioning cylinder 34 through the lifting cylinder 36. Under the influence of the rotational force, the upper second gear disk 32 will continuously control the upper spring 311 to move up and down inside the key rod 310. The user needs to rotate the first gear disk 31 to rotate and adjust the first adjusting rod 41 to the forty-five-degree direction, and then needs to rotate the second gear disk 32 to rotate and adjust the second adjusting rod 45 to the forty-five-degree direction. A cross-shaped ninety-degree angle structure is formed between the first positioning plate 42 and the second positioning plate 46. Then the user can place the tank body 9 between the first positioning plate 42 and the second positioning plate 46;

[0077] Step S2: When the tank body 9 is placed, the bottom of the tank body 9 applies a downward force to the upper part of the second gear disk 32. The bottom of the tank body 9 first contacts the top disk 38. The downward force continuously controls the top disk 38 to compress and descend the spring rod 37. During the descent, it will control the upper spring 311 to control the second gear disk 32 to descend and continuously engage to control the first gear disk 31 to descend. At this time, the lower spring 35 is compressed. Finally, when the first gear disk 31 descends, it will control the slide rod 54 to descend and drive the limit spring 56 to extend. During the descent of the slide rod 54, the trigger rod 55 is synchronously driven to descend. When the trigger rod 55 descends, the outer inclined plane causes the two lock plates 53 to move outward along the taper of the trigger rod 55. Through the movement of the lock plates 53, frictional force can be formed with the inner wall of the locking groove 8, ensuring that the tank body 9 can be automatically locked after being placed;

[0078] When the placed tank body needs to be transported, the user can set a trajectory program for the base 1 of the pallet robot. The rotation and movement of the base 1 of the pallet robot can drive the placed tank body above for transportation.

[0079] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
